76381436 | 76381929 | I am using ST_Intersects to check if two polygons intersect. Relevant part of my query is:
SELECT entity_number
FROM coordinates
WHERE ST_INTERSECTS($1, location)
It works well to determine if one polygon crosses the other's surface:
I expected ST_Intersects to return false when two polygons share sides, but it does not:
I read about other methods like ST_Covers, ST_Contains, ST_ContainsProperly, ST_Within ,ST_DWithin. But i am not sure which one suits my needs.
Is there any method that allows two polygons to share sides?
| Is there ST_Intersects alternative that allows two(or more) polygons to share sides | You want ST_Overlaps:
Returns TRUE if geometry A and B "spatially overlap". Two geometries overlap if they have the same dimension, each has at least one point not shared by the other (or equivalently neither covers the other), and the intersection of their interiors has the same dimension. The overlaps relationship is symmetrical.

76385016 | 76385223 | I'm using React Router v6 and following are my routes:
const router = createBrowserRouter([
{
path: '/',
element: <App />,
errorElement: <ErrorPage />,
children: [
{
index: true,
element: <HomePage />,
},
{
path: '/sign-up',
element: <SignUpPage />,

{
path: '/log-in',
element: <LogInPage />,

],
},
]);
const root = ReactDOM.createRoot(
document.getElementById('root') as HTMLElement,
);
root.render(
<React.StrictMode>
<RouterProvider router={router} />
</React.StrictMode>,
);
The App component contains my app's layout and outputs the route elements using the Outlet component. But now if there's an error that bubbles up to the root route, then the ErrorPage gets displayed as expected, but it doesn't make use of the layout from App... So, how can I reuse my layout from App when the error page gets displayed?
| React Router - How can I reuse my layout for the errorElement in the root route? | When there's an error it is kind of an either or kind of scenario. Either conditions are fine and the App component is rendered or there's an error condition and the ErrorPage component is rendered.
What you could do is to abstract the layout portion of the App component into a layout component on its own that can render either a passed children prop or the Outlet component for the nested route, and render it in App and also wrap the ErrorPage component.
Example:
const AppLayout = ({ children }) => (
...
{children ?? <Outlet />}
...
);
const App = () => (
...
<AppLayout />
...
);
const router = createBrowserRouter([
{
path: "/",
element: <App />, // <-- uses Outlet
errorElement: (
<AppLayout> // <-- uses children
<ErrorPage />
</AppLayout>

76381457 | 76381967 | I'm learning flutter and I have made an app that looks like this:
I'm facing a problem as to how to fix the container fixed on a particular spot on the screen like it has to be aligned to the top center. Here's the problem I'm facing:
Here's the code:
class Program7 extends StatefulWidget {
const Program7({super.key});

76384931 | 76385224 | I have 2 data frames
df1
+--------------------+---+--------------------+--------------------+
| ID |B |C | D |

+--------------------+---+--------------------+--------------------+
| 1|100| 1.0| 100|
+--------------------+---+--------------------+--------------------+
If ID in df2 matches an ID in df1, I want to replace the row in df1 with the updated values in df2. So the new df1 looks like:
df1
+--------------------+---+--------------------+--------------------+
| ID |B |C | D |
+--------------------+---+--------------------+--------------------+
| 1|100| 1.0| 100|

| 4|4.0| 4.0| 4.0|
+--------------------+---+--------------------+--------------------+
I've been trying to figure this out with union and join and just not having any luck yet. I first created a new dataframe based on filtering for the ID of df1 and that works and I called that dataframe matchedDF that looks like:
matchedDF (dataframe based on finding a match of ID 1 in df1)
+--------------------+---+--------------------+--------------------+
| ID |B |C | D |
+--------------------+---+--------------------+--------------------+
| 1|1.0| 1.0| 1.0|
+--------------------+---+--------------------+--------------------+
But I don't know if I just want to delete the original ID 1 in df1 and add the new matchedDF or do I somehow want to update the original ID 1 with the matchedDf? Or am I approaching this all wrong?
Thanks
| How to replace a spark dataframe row with another spark dataframe's row using java | To stay computationally efficient, it's always a good idea to avoid joins/shuffles where possible.
This looks like a case where it is possible to avoid joining, have a look at the following code (it is in Scala, but the principles remain the same):
// Constructing the 2 dfs
val df = Seq(
(1, 1.0, 1.0, 1.0),
(2, 2.0, 2.0, 2.0),
(3, 3.0, 3.0, 3.0),
(4, 4.0, 4.0, 4.0)
).toDF("ID", "B", "C", "D")
val df2 = Seq(
(1, 100, 1.0, 100),
(2, 100, 1.0, 100)
).toDF("ID", "B", "C", "D")
// Collecting the IDs to be updated into a single Array
// IMPORTANT: we make the assumption that this array is not large (in your
// example there is only 1 row here, so the array only has 1 element which is
// totally fine)
val newIds = df2.select("ID").collect.map(_.getInt(0))
// Removing the original rows with the unwanted IDs and unioning the result with
// the new rows
val output = df
.filter(not(col("ID").isin(newIds: _*)))
.union(df2)
scala> output.show
+---+-----+---+-----+
| ID| B| C| D|
+---+-----+---+-----+
| 3| 3.0|3.0| 3.0|
| 4| 4.0|4.0| 4.0|
| 1|100.0|1.0|100.0|
| 2|100.0|1.0|100.0|
+---+-----+---+-----+
So basically, if we can make the assumption that df2 (with the new values) is small like in your example, you can do something like the following:
collect the ID values into a single (undistributed) Array. From your example it seems like this is OK. If the amount of new rows is really large this might not be the best approach
filter the original df using the isin method of a column and negating using not (basically removing the rows with the new IDs)
union the filtered df and df2, resulting in the rows being updated WITHOUT any expensive operation like a shuffle

76381864 | 76382001 | I have made this code to find the distance between stations but in the output, there is only one value. Can you find the error?

}
distance_df <- as.data.frame(my_points)
| Make a loop to find the distance between stations in R | There are two issues here:
Your input data frame might not look the way you expect it to - the latitude and longitude columns are recycled so you have multiple different coordinates for the same station. Try adding rep() in the lat and long columns as well as station.
In your code lat1 <- df$latitude[df$station == stations[i]] returns a vector, because there are multiple matches. I think you're expecting a single value. Use only the first matching element (since they are now all the same elements in the vector after adding rep() as above):
df <- data.frame(
station = rep(c("A", "B", "C", "D"), each = 20),
temperature = rnorm(80),
latitude = rep(c(40.7128, 34.0522, 41.8781, 39.9526), each = 20),
longitude = rep(c(-74.0060, -118.2437, -87.6298, -75.1652), each = 20)
)
stations <- unique(df$station)
my_points <- matrix(NA, nrow = length(unique(df$station)), ncol = length(unique(df$station)))
# Loop through each station combination
for (i in 1:length(stations)) {
for (j in 1:length(stations)) {
# Get temperatures for the two stations
lat1 <- df$latitude[df$station == stations[i]][1]
lon1 <- df$longitude[df$station == stations[i]][1]
lat2 <- df$latitude[df$station == stations[j]][1]
lon2 <- df$longitude[df$station == stations[j]][1]
my_points[i, j] <- as.vector(dist(matrix(c(lon1,lon2,lat1,lat2),
nrow = 2)))
}
}
distance_df <- as.data.frame(my_points)
This gives:
V1 V2 V3 V4
1 0.000000 44.73631 13.67355 1.386235
2 44.736313 0.00000 31.59835 43.480707

4 1.386235 43.48071 12.61245 0.000000
A slightly better way of finding unique stations:
unique(df[, c("station", "latitude", "longitude")])
You can then loop over those instead:
# Loop through each station combination
for (i in 1:length(stations)) {
for (j in 1:length(stations)) {
# Get temperatures for the two stations
lat1 <- unique_df$latitude[unique_df$station == stations[i]]
lon1 <- unique_df$longitude[unique_df$station == stations[i]]
lat2 <- unique_df$latitude[unique_df$station == stations[j]]
lon2 <- unique_df$longitude[unique_df$station == stations[j]]
my_points[i, j] <- as.vector(dist(matrix(c(lon1,lon2,lat1,lat2),
nrow = 2)))
}

76381890 | 76382014 | Im developing a shiny app with several features. I added a button to download a single pdf file that contains many plots. I want to save those plots in individual pages but I want to choose the size of each pdf page. Is that possible?
This is he code that have so far:
output$exportall<-downloadHandler(
filename="Allplots.pdf",
content=function(file){
withProgress(message = 'Exporting', min=0,max=1, {
pdf(file,width=8,height=11)
print(plot1())
print(histogram())
print(plots2())
print(marrangeGrob(woodsbytimepoint(), nrow=2, ncol=1))
print(digestion())
print(map())
print(marrangeGrob(allplots(), nrow=4, ncol=2, top=NULL))
dev.off()
})
}
)
The code works fine and exports all the plots that I want. However, all pages in the pdf file are 8x11. Is there a way to speciffy the size of each page? for example I want the first plot to be 7x7 and all other 8x11.
Any ideas?
| save multiple pdf pages with different sizes in Shiny R | Perhaps the simplest is to create separate PDFs (sized appropriately) and combine them with qpdf::pdf_combine.
file <- "file.pdf"
pdf(paste0(file, ".8x11"), width=8, height=11)
plot(disp ~ mpg, data = mtcars)
gg <- ggplot(mtcars, aes(disp, mpg)) + geom_point()
print(gg)
dev.off()
pdf(paste0(file, ".7x7"), width=7, height=7)
print(gg) # or anything else
dev.off()
qpdf::pdf_combine(paste0(file, c(".8x11", ".7x7")), file)
file.remove(paste0(file, c(".8x11", ".7x7")))
The resulting file.pdf pages:
If your sizes are not always in order (e.g., 8x11, 7x7, 8x11), you can either:
create three PDF files (would need an adjusted file name convention) and concatenate in order, or
create two PDF files (by dimensions), then also use qpdf::pdf_subset ... though since this creates new PDF files that you would then need to include in pdf_combine, it hardly seems the most efficient method.
I cannot test this, but I think this means your code should be
output$exportall<-downloadHandler(
filename="Allplots.pdf",
content=function(file){
withProgress(message = 'Exporting', min=0,max=1, {
pdf(paste0(file, ".7x7"), width=7, height=7)

76381693 | 76382030 | How do I correct my code to be able to order its elements according to which has the canonical vector with a value equal to 1.0 in the element closest to the beginning of its sublists (ignoring the first sublist, which is the one with the titles, although this will also change position according to the position of element 1.0 in the other remaining ones), thus remaining?
matrix = [['B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'], [8, 2.0, 1.0, -1.0, 0, 0, 1.0, 0], [2, 1.0, 1.0, 0, 1.0, 0, 0, 0], [8, 1.0, 2.0, 0, 0, -1.0, 0, 1.0]]
matrix_aux = [['X4', 'U1', 'U2'], [0, 1.0, 0], [1.0, 0, 0], [0, 0, 1.0]]
#Extract the first title sublist
titles = matrix_aux.pop(0)
#Create a list of tuples, and sort it
tuple_list = [(sublist.index(1.0), sublist) for sublist in matrix_aux]
sorted_tuples = sorted(tuple_list, key=lambda x: x[0])
#Rebuild the sorted array
matrix_aux_ord = [[titles[i] for i in range(len(titles))]] + [sublist for _, sublist in sorted_tuples]
print(matrix_aux_ord)
for row in matrix_aux_ord: print(row) #print in matrix format
the problem now with my code is that it forgets to sort the row of titles or headers ['X4', 'U1', 'U2'], incorrectly printing this matrix
[['X4', 'U1', 'U2'], [1.0, 0, 0], [0, 1.0, 0], [0, 0, 1.0]]
instead of this that if it maintains consistency
[['U1', 'X4', 'U2'], [1.0, 0, 0], [0, 1.0, 0], [0, 0, 1.0]]
Then, having these 2 matrices, build the new matrix called new_matrix, in which I would add a column in front of the matrix, that is, I would add an element to each of the sublists that make up the rows of matrix, to the first sublist of the matrix called matrix add an 'X' before it as the first element, and to the rest of the sublists of the matrix called matrix add as the first element in an ordered manner the elements of the first sublist of the matrix called matrix_aux_ord
matrix = [['B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'], [8, 2.0, 1.0, -1.0, 0, 0, 1.0, 0], [2, 1.0, 1.0, 0, 1.0, 0, 0, 0], [8, 1.0, 2.0, 0, 0, -1.0, 0, 1.0]]
#If the previous code worked, it would get this array sorted like this...
matrix_aux_ord = [['U1', 'X4', 'U2'], [1.0, 0, 0], [0, 1.0, 0], [0, 0, 1.0]]
#Add the column title or header 'X' to the front of the first sublist of matrix
matrix[0].insert(0, 'X')
So the resulting final matrix, the correct output, called as new_matrix, would look like this:
new_matrix = [['X', 'B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'], ['U1', 8, 2.0, 1.0, -1.0, 0, 0, 1.0, 0], ['X4', 2, 1.0, 1.0, 0, 1.0, 0, 0, 0], ['U2', 8, 1.0, 2.0, 0, 0, -1.0, 0, 1.0]]
What should I do to get the matrix_aux_ord correctly, and with it to be able to get the matrix new_matrix which basically consists of a way to combine amber matrices, matrix and matrix_aux_ord?
| How to sort array elements based on the closest occurrence of a sublist with a numeric value of 1.0? And then combine this sorted matrix with another | You need to sort the titles together with the other lists. You can do it with zip

matrix_aux = [['X4', 'U1', 'U2'], [0, 1.0, 0], [1.0, 0, 0], [0, 0, 1.0]]
matrix_aux_ord = list(zip(*sorted(zip(*matrix_aux), key=lambda x: x[1:].index(1.0))))
print(matrix_aux_ord)
# [('U1', 'X4', 'U2'), (1.0, 0, 0), (0, 1.0, 0), (0, 0, 1.0)]

titles = ['X'] + list(matrix_aux_ord[0])
new_matrix = [[titles[i]] + matrix[i] for i in range(len(titles))]
print(new_matrix)

76384846 | 76385239 | I have a React website where I have 2 toggles for different kinds of cards - one of them is Live markets (this type has a timer component).
Here is the problem- When I switch to classifieds and I switch back to live markets -
Auction timer for the first card becomes NaN. Note: this only happens to the first card, the other timers are fine.
I have a CardsLayout component, which send a request to the server for data when the above toggle is changed. And if it is in Live Markets tab, then the CardsLayout component maps each object to an AuctionCard component which has a Timer component inside it.
Here is the code for the Timer component-
import { useState, useEffect } from 'react';
export default function Timer({ id, endTime}) {
const [remainingTime, setRemainingTime] = useState(getRemainingTime());
useEffect(() => {
const interval = setInterval(() => {
setRemainingTime(getRemainingTime());
}, 1000);
return () => clearInterval(interval);
}, []);
function getRemainingTime() {
const now = new Date();
const end = new Date(endTime);
const diff = end.getTime() - now.getTime();
const days = Math.floor(diff / (1000 * 60 * 60 * 24));
const hours = Math.floor((diff / (1000 * 60 * 60)) % 24);
const minutes = Math.floor((diff / (1000 * 60)) % 60);
const seconds = Math.floor((diff / 1000) % 60);
return { days, hours, minutes, seconds };
}
console.log('endtime-',id,endTime)
console.log('remtime-',id,remainingTime.seconds)
return (
<div className={remainingTime.seconds < 0 ? 'timer-ended' : 'timer'}>
{remainingTime.seconds < 0 ? (
"Auction over"
) : (
<>
Auction time remaining: {remainingTime.days} Days {remainingTime.hours}:
{remainingTime.minutes}:{remainingTime.seconds}
</>
)}
</div>
);
}
I also have 2 console statements. The values are getting printed every second. Here is whats getting printed for the Timer with NaN-
endtime- 4 2023-06-09T20:30:00.000Z
remtime- 4 NaN
| The first timer in a react component list is getting value NaN | Since it works after you add id and endTime as dependencies to the useEffect (as mentioned in the comments of the OP), it seems that the issue is that the first render you do of the first Time is done without/or with a wrong endTime so it end up displaying NaN.
Subsequent renders, I assume after fetching the data from somewhere, provide a valid endTime value for that property.
Initially the change in that prop would not alter the functionality of the ongoing interval, since the getRemainingTime would refer to the initial value of endTime.
There are a few solutions to this problem.
Do not render the Timer component until after you have valid data to provide to it. This need to be handled at the component using the Timer and not inside it.
Provide a key for the Timer component when using it (<Timer key={/*what ever you use for id will most likely work here too*/} id={..} endTime={..} /> that is unique and would change once you get the data from the remote location.
Use correct dependencies for the useEffect.
For 3. the more correct approach is not to add id and endTime to the useEffect but to use useCallback, with endTime for the getRemainingTime and then use that as dependency for the useEffect.
const getRemainingTime = useCallback(function() {
const now = new Date();
const end = new Date(endTime);
const diff = end.getTime() - now.getTime();
const days = Math.floor(diff / (1000 * 60 * 60 * 24));
const hours = Math.floor((diff / (1000 * 60 * 60)) % 24);
const minutes = Math.floor((diff / (1000 * 60)) % 60);
const seconds = Math.floor((diff / 1000) % 60);
return { days, hours, minutes, seconds };
}, [endTime]);
useEffect(() => {
const interval = setInterval(() => {
setRemainingTime(getRemainingTime());
}, 1000);
return () => clearInterval(interval);
}, [getRemainingTime]);

76382470 | 76383422 | Can someone explain me why the following code fails for GCC 8.5 with NaNs?
bool isfinite_sse42(float num)
{
return _mm_ucomilt_ss(_mm_set_ss(std::abs(num)),
_mm_set_ss(std::numeric_limits<float>::infinity())) == 1;
}
My expectation for GCC 8.5 would be to return false.
The Intel Intrinsics guide for _mm_ucomilt_ss says
RETURN ( a[31:0] != NaN AND b[31:0] != NaN AND a[31:0] == b[31:0] ) ? 1 : 0
i.e., if either a or b is NaN it returns 0. On assembly level (Godbolt) one can see a ucomiss abs(x), Infinity followed by a setb.
# GCC8.5 -O2 doesn't match documented intrinsic behaviour for NaN
ucomiss xmm0, DWORD PTR .LC2[rip]
setb al
Interestingly newer GCCs and Clang swap the comparison from a < b to b > a and therefore use seta. But why does the code with setb returns true for NaN and why seta returns false for NaN?
| What causes the different NaN behavior when compiling `_mm_ucomilt_ss` intrinsic? | GCC is buggy before GCC13, not implementing the documented semantics of the intrinsic for the NaN case which require either checking PF separately, or doing it as ucomiss Inf, abs so the unordered case sets CF the same way as abs < Inf.
See https://www.felixcloutier.com/x86/ucomiss#operation or the nicer table in https://www.felixcloutier.com/x86/fcomi:fcomip:fucomi:fucomip . (All x86 scalar FP compares that set EFLAGS do it the same way, matching historical fcom / fstsw / sahf.)

Notice that CF is set for both the left < right and unordered cases, but not for the other two cases.
If you can arrange things such that you can check for > or >=, you don't need to setnp cl / and al, cl to rule out Unordered. This is what clang 16 and GCC 13 do to get correct results from ucomiss inf, abs / seta.
GCC8.5 does the right thing if you write abs(x) < infinity, it's only the scalar intrinsic that it doesn't implement properly. (With plain scalar code, it uses comiss instead of ucomiss, the only difference being that it will update the FP environment with a #I FP-exception on QNaN as well as SNaN.)
This requires a separate movss load instead of a memory source. But this does let GCC avoid the useless SSE4.1 insertps instruction that zeros the high 3 elements of XMM0, which ucomiss doesn't read anyway. Clang sees that and optimizes away that part of _mm_set_ss(num) but GCC doesn't. The lack of an efficient way to go from a scalar float to a __m128 with don't-care upper elements is a persistent problem in Intel's intrinsics API that only some compilers manage to optimize around. (How to merge a scalar into a vector without the compiler wasting an instruction zeroing upper elements? Design limitation in Intel's intrinsics?) A float is just the low element of a __m128.

Where $1 is the "specific column" and yourstring is the string you are searching for.
This prints each line and then checks for the occurrence of yourstring in the first column. If it finds it, it tests a variable found which we increment, to see if it hits 2. If so awk exits.
Edit: If instead you want to delete the second occurrence (as well as everything after), flipping the two blocks around will accomplish this:

The pattern is the following:
Assuming that size is the total size of the triangle (which is 19 in your case), then
line n consists of one *
followed by n-2 spaces
followed by one *
followed by (size/2) - n spaces
followed by one *
followed by (size/2) - n spaces
followed by one *
followed by n-2 spaces
followed by one *.
Note that in C, the result of 19 / 2 is 9, as the fractional part of the division is discarded.
Using this information about the pattern, you should be able to create a loop that in every loop iteration, prints one line as described above. That way, you should be able to solve the problem of printing the lines 2 to 9.
Printing the lines 11 to 19 should be easy afterwards, because these lines must only be printed in reverse order of the lines 2 to 9.
In accordance with the community guidelines for homework questions, I will not provide the full solution at this time. I can provide further information later, if necessary.
EDIT:
Since several other solutions have already been posted by other users, I will now also post my solution, which solves the problem as described above:
#include <iostream>
const int MAP_SIZE = 19;
static_assert( MAP_SIZE % 2 == 1, "MAP_SIZE must be odd" );
int main( void )
{
//print first horizontal line
for ( int i = 0; i < MAP_SIZE; i++ )
std::cout << '*';
std::cout << '\n';
//print top half of flag
for ( int i = 0; i < MAP_SIZE / 2 - 1; i++ )
{
std::cout << '*';
for ( int j = 0; j < i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < MAP_SIZE/2 - 2 - i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < MAP_SIZE/2 - 2 - i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < i; j++ )
std::cout << ' ';
std::cout << '*';
std::cout << '\n';
}
//print second horizontal line
for ( int i = 0; i < MAP_SIZE; i++ )
std::cout << '*';
std::cout << '\n';
//print bottom half of flag
for ( int i = 0; i < MAP_SIZE / 2 - 1; i++ )
{
std::cout << '*';
for ( int j = 0; j < MAP_SIZE/2 - 2 - i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < i; j++ )
std::cout << ' ';
std::cout << '*';
for ( int j = 0; j < MAP_SIZE/2 - 2 - i; j++ )
std::cout << ' ';
std::cout << '*';
std::cout << '\n';
}
//print third horizontal line
for ( int i = 0; i < MAP_SIZE; i++ )
std::cout << '*';
std::cout << '\n';
}
However, I think that this problem is easier to solve using a 2D array (which you stated that you are not allowed to use). The 2D array is initialized to spaces and then the 3 horizontal, 3 vertical and 2 diagonal lines are drawn:
#include <iostream>
const int MAP_SIZE = 19;
static_assert( MAP_SIZE % 2 == 1, "MAP_SIZE must be odd" );
int main( void )
{
char map[MAP_SIZE][MAP_SIZE];
//initialize 2D array to spaces
for ( int i = 0; i < MAP_SIZE; i++ )
for ( int j = 0; j < MAP_SIZE; j++ )
map[i][j] = ' ';
//draw the 3 horizontal lines
for ( int i = 0; i < MAP_SIZE; i++ )
{
map[ 0][i] = '*';
map[MAP_SIZE/2][i] = '*';
map[MAP_SIZE-1][i] = '*';
}
//draw the 3 vertical lines
for ( int i = 0; i < MAP_SIZE; i++ )
{
map[i][ 0] = '*';
map[i][MAP_SIZE/2] = '*';
map[i][MAP_SIZE-1] = '*';
}
//draw the 2 diagonal lines
for ( int i = 0; i < MAP_SIZE; i++ )
{
map[i][ i] = '*';
map[i][MAP_SIZE-i-1] = '*';
}
//print the result
for ( int i = 0; i < MAP_SIZE; i++ )
{
std::cout.write( map[i], MAP_SIZE );
std::cout.put( '\n' );
}
}

Consider the tables bellow:

I want to get the Value from Table2 into Table1. But for some reason when I use the built-in power query editor merge with fuzzy matching. It will match Apple Fruit A11 with Berry A11 instead of Apple A11 R/T. I've read the documentation, and it says that the built-in function works best with single words. I tried to remove spaces both from Table1[Name] and Table2[Name] but it didn't improve results.
I looked around trying to find a solution, but wasn't able to figure out yet. Is there a way to do this using python? Or is there a simpler solution?
The results that I am expecting:
Table1
Expected Result

76381116 | 76382168 | Problem: running get_pi_ij() gives the error:
Error in as.vector(x, mode) : cannot coerce type 'closure' to vector of type 'any'
Called from: as.vector(data)
The first thing this function does is to make the resulting alphas and beta_prelims into matrixes that match c so that they can be calculated together. This is where something goes wrong, and I have not been able to figure out what. If I use <<- to save the alphas and betas to the global environment in the prior functions for alphas and betas and replace that with those in the faulty function, it works. So I assume it has to do with how I call the functions inside the matrix creation.
get_pi_ij <- function() {
alphas <-
matrix(get_alpha(),
nrow = length(get_alpha()),
ncol = length(get_alpha()),
byrow = FALSE)
betas <-
matrix(get_beta_prelim,
nrow = length(get_beta_prelim()),
ncol = length(get_beta_prelim()),
byrow = TRUE)
pi_ij <- exp(alphas + betas + gamma * c)
return(pi_ij)
}
get_pi_ij()
I added the full code cause it's not too long and the first parts are just definitions. Makes it easier to test it.

| How to Fix NoMethodError Issue with Ruby Compass (1.0.0 and 1.0.3) | File.exists? was deprecated for several minor versions and existed until Ruby 2.7. And was finally removed in Ruby 3.0.
Whereas the last version of the compass gem is more than 8 years old. That means it doesn't work with current version of Ruby anymore.
You have basically three options:
Downgrade your Ruby version to, for example, 2.7.8. That version is not terrible out-dated, but keep in mind that Ruby 2.7 reached end-of-life, it will not get any security or bug fixes anymore.
Fork the compass gem and fix the usage of File.exists? with File.exist?. This seems to be a quick fix, but given that this gem didn't get any update in the last 8 years, you might discover further compatibility issues or unfixed bugs.
Search for an alternative and replace that gem.

It can be done by registry by adding "%V" as argument to command to console app, for example, "C:\myfolder\myapp.exe" "%V". Hence, this %V gives folder path to argument list of main() of myuapp.exe. Easy huh!
How it can be done using shell extension menu handler? I wrote a simple shell context menu dll which works fine and do its job, except that I don't known how to get that folder path as string where user made right click in background.
I found that path comes as PCIDLIST_ABSOLUTE pidl argument in IShellExtInit::Initialize() method. But, I couldn't get it in simple string format. The code is below which crashes, of course.
HRESULT __stdcall Initialize(PCIDLIST_ABSOLUTE pidlFilder, IDataObject* pdtobj, HKEY hkeyProgID)
{
std::wstring s = L"null";
// check msg, this msgbox is shown as expected
MessageBox(NULL, L"Before", L"Initialize()", MB_OK);
//have problem in this line, I guess
SHGetPathFromIDList((LPCITEMIDLIST) pidlFilder, (PWSTR) &s);
// check msg, sometimes this msgbox is also shown as expected
MessageBox(NULL, L"After", L"Initialize()", MB_OK);
// but this msgbox is never shown. I removed it but code still crashes
MessageBox(NULL, std::wstring(s).c_str(), L"Initialize()", MB_OK);
return S_OK;
}
When I right click on folder background, it crashes and explorer restarts.
Does anyone know the problem and its solution? How to get folder path when right clicking background of folder to invoke context menu using shell extension?
In addition, how to get file/folder path when right clicking on it to invoke context menu using shell extension?
Thanks in advance
tried using this code too, still crashes
IShellFolder *sf = NULL;
STRRET pName = {};
sf->GetDisplayNameOf(pidlFilder, SHGDN_FORPARSING, &pName);
wchar_t *d = new wchar_t;
lstrcpyW(d,L"nulld");
size_t inst = MAX_PATH, outst ;
mbstowcs_s(&outst, d, inst, pName.cStr, MAX_PATH);
s = std::wstring(d);
MessageBox(NULL, std::wstring(s).c_str(), L"Initialize()", MB_OK);
| How can I obtain the folder path when right-clicking the background of a folder and invoking a context menu using a shell extension? | You are trying to make SHGetPathFromIDList() write the string data to the memory address where a std::wstring object resides, which will not work.
Use a fixed WCHAR[] array instead, eg:
HRESULT __stdcall Initialize(PCIDLIST_ABSOLUTE pidlFilder, IDataObject* pdtobj, HKEY hkeyProgID)
{
WCHAR szPath[MAX_PATH] = {};
SHGetPathFromIDList(pidlFilder, szPath);
MessageBox(NULL, szPath, L"Initialize()", MB_OK);
return S_OK;
}
Alternatively, if you want to receive the string data into a std::wstring object, then you have to pre-allocate its internal character buffer and then receive into that buffer, eg:
HRESULT __stdcall Initialize(PCIDLIST_ABSOLUTE pidlFilder, IDataObject* pdtobj, HKEY hkeyProgID)
{
std::wstring s;
s.resize(MAX_PATH);
SHGetPathFromIDList(pidlFilder, s.data() /* or &s[0] before C++17 */ );
s.erase(s.find(L'\0'));
MessageBox(NULL, s.c_str(), L"Initialize()", MB_OK);
return S_OK;
}
Otherwise, you can simply receive into a WCHAR[] and then assign that to your std::wstring, eg:
HRESULT __stdcall Initialize(PCIDLIST_ABSOLUTE pidlFilder, IDataObject* pdtobj, HKEY hkeyProgID)
{
WCHAR szPath[MAX_PATH] = {};
SHGetPathFromIDList(pidlFilder, szPath);
std::wstring s = szPath;
MessageBox(NULL, s.c_str(), L"Initialize()", MB_OK);
return S_OK;
}
Your 2nd example doesn't work for several reasons:
Your IShellFolder *sf doesn't point anywhere meaningful. Use SHGetDesktopFolder() to get the top-level IShellFolder object which you can then use to parse pidlFilder.
you are allocating only 1 wchar_t for wchar_t *d to point at, but then you are trying to copy more than 1 wchar_t into that memory. You don't really need to allocate any memory at all, as the parsed STRRET already contains the necessary string data, so just use it as-is. Otherwise, you can pass the STRRET to StrRetToBuf() or StrRetToStr() to get the data in a more usable format.
you are not paying attention to the STRRET::uType field to know what kind of string data it is holding. Don't access the cStr field unless the uType field is set to STRRET_CSTR. StrRetToBuf()/StrRetToStr() will handle this for you.
Try this instead:
HRESULT __stdcall Initialize(PCIDLIST_ABSOLUTE pidlFilder, IDataObject* pdtobj, HKEY hkeyProgID)
{
IShellFolder *sf = NULL;
if (SUCCEEDED(SHGetDesktopFolder(&sf))
{
STRRET pName = {};
if (SUCCEEDED(sf->GetDisplayNameOf(pidlFilder, SHGDN_FORPARSING, &pName))
{
WCHAR szPath[MAX_PATH] = {};
StrRetToBufW(&pName, pidlFilder, szPath, MAX_PATH);
MessageBox(NULL, szPath, L"Initialize()", MB_OK);
}
sf->Release();
}
return S_OK;
}

I know that the $?evaluates to the returned value of the last executed command.

| Bash if statement expression evaluates to FALSE but $? is 0, why? | According to man bash:

The if list is executed. If its exit status is zero, the then list is executed. Otherwise, each elif list is executed in turn, and if its exit status is zero, the corresponding then list is executed and the
command completes. Otherwise, the else list is executed, if present. The exit status is the exit status
of the last command executed, or zero if no condition tested true.

76385245 | 76385381 | I have a user-settable text, where the default one is [Log in] or [register] to view the content.
What I need, is to wrap the two words in square brackets in their respective links. But first, I need to check that the user didn't change this default text, in other words that they kept the square brackets. I won't go in great lengths in checking this. Just the existence of two sets of square brackets is enough. If that's the case, then I'll assume that the first link is for the login page, and the second is for the register-an-account page...
So, the if below does the job for me:
if ( preg_match( '/\[(.*?)\].*\[(.*?)\]/', $text ) )
Then, inside the if, my plan was to perform a str_replace() with two arrays like this:
$text = str_replace( array( '[', ']', '[', ']' ), array( '%1$s', '%2$s', '%3$s', '%4$s' ), $text );
But this doesn't work the way I thought it would. I thought that since the two arrays have equal number of elements it'd do a 1-on-1 search and replace, meaning that it would turn the text to %1$sLog in%2$s or %3$sregister%4$s to view the content, whereas it turned to %1$sLog in%2$s or %1$sregister%2$s to view the content.
Why is that? If that's not the proper way to do that (which obviously isn't), what should I do instead?
Any help would be very much appreciated. TIA.
| Strange behavior of str_replace | Try using preg_replace with your same pattern (with additional capture):
$text = preg_replace('/\[(.*?)\](.*)\[(.*?)\]/', '%1$s$1%2$s$2%3$s$3%4$s', $text);
which produces
%1$sLog in%2$s or %3$sregister%4$s to view the content
The str_replace does not work the way you intended - the first array is an array of needles which has no sense of position so the second set of [] are duplicate needles in your case.

76383155 | 76383536 | I use ListView to dynamically display items in my JavaFX app. Items are loaded through REST call to my backend app. Each item can be clicked and then product view is displayed instead of product list. That works (looks) fine until app window is resized. After resize, items look ugly and they use too much space.
The question: Is there a way to get some kind of fluid item order?
In HTML and CSS that would be Flexbox if I remember well.
All items would be the same width and the same height not giving a chance to calculate width or height for each item separately.
The only solution I found on the internet is here: https://github.com/onexip/FlexBoxFX -
but it uses FXML files only and there is no option to add items dynamically. The last project update is 6 years ago which tells me it's abandoned or poorly maintained. Their official website is dead: http://flexboxfx.io
EDIT: As James_D mentioned, I don't need ListView but any other solution that works.
Also I am aware of WebView but I would like to avoid HTML content in my app.
To make my case more clear, I made some screenshots and the first one is edited to represent the idea what I want. Numbers on edited screenshot represent desired order of items.
If window grows more in width, first row should have items 1, 2 and 3, next row 4, 5 and 6, next row 7, 8 and 9 and last row should have only one item (10). All rows should be centered and item 10 of last row should be positioned below item 8.
This is the final layout I want to get but I don't know how.
Everything is nice when window is not resized, but after resize, it looks ugly.
| Fluid nodes list layout with JavaFX | The primary purpose of a ListView is to provide virtualization; i.e. it provides an efficient mechanism to display a large number of items, letting the user scroll through them, without the overhead of UI components for the items that are not currently displayed. It also provides some additional functionality, such as selection (allowing the user to put one or more items in the list into a "selected" state which is shown visually).
If you actually need virtualization, and perhaps selection, and want a grid-like layout, then the third-party library ControlsFX provides a similarly-virtualized GridView.
However, your question appears to be only about layout and your screenshots appear to show you using a Pagination control, which would (probably) obviate the need for virtualization anyway. If you don't need the functionality of the ListView, then a standard layout pane such as FlowPane or TilePane, possibly wrapped in a ScrollPane, should provide the layout you need.

| Add New Polygon to Dash Leaflet Map via a Callback | It looks like the callback approach above is valid, I was just providing the wrong data type back to the dl.GeoJSON's data attribute .

to

76385364 | 76385392 | When upgrading AWS RDS aurora postgresql cluster from 11.17 -> 15.2, I was met with this fatal error in the pg_upgrade logs:
fatal
Your installation contains user-defined objects that refer to internal
polymorphic functions with arguments of type "anyarray" or "anyelement".
These user-defined objects must be dropped before upgrading and restored
afterwards, changing them to refer to the new corresponding functions with
arguments of type "anycompatiblearray" and "anycompatible".
AWS does not mention this in the upgrade docs, so I thought the changed may have been introduced by a system user. After a bit of digging, it seems that the aggregate functions changed the way the types are named (in postgresql version 14 to be clear). So how do I update this?
I ran a subset the query that the upgrade failed on, on each DB in the target cluster:
--find incompatibilites on each DB:
\c <DATABASE>
SELECT 'aggregate' AS objkind,
p.oid::regprocedure::text AS objname
FROM pg_proc AS p
JOIN pg_aggregate AS a ON a.aggfnoid=p.oid
JOIN pg_proc AS transfn ON transfn.oid=a.aggtransfn
WHERE p.oid >= 16384
AND a.aggtransfn = ANY(ARRAY['array_append(anyarray,anyelement)', 'array_cat(anyarray,anyarray)', 'array_prepend(anyelement,anyarray)', 'array_remove(anyarray,anyelement)', 'array_replace(anyarray,anyelement,anyelement)', 'array_position(anyarray,anyelement)', 'array_position(anyarray,anyelement,integer)', 'array_positions(anyarray,anyelement)', 'width_bucket(anyelement,anyarray)']::regprocedure[]);
objkind | objname
-----------+-------------------------
aggregate | array_accum(anyelement)
(1 row)
Okay, so now what?
| Updating "anyarray" or "anyelement" polymorphic functions when upgrading to 14.x or higher on AWS RDS aurora postgresql | Solution:
--drop aggregate from sub 14.x db
mygreatdatabase=> DROP AGGREGATE array_accum(anyelement);
DROP AGGREGATE
--upgrade to 14.x or higher, and then re-create using updated type:
mygreatdatabase=> CREATE AGGREGATE array_accum(anycompatible) (SFUNC = array_append,STYPE = anycompatiblearray,INITCOND = '{}');
My hope is that AWS adds this to the documentation on RDS Aurora PostgresQL Upgrade Pre-Checks, but this will be here until that is more clear.

| My bootstrap column not working on small screen | Instead of trying to position each button individually in the middle of the page, position the entire row of buttons. This will allow you to use Bootstrap columns better. You were also missing the the extra-small (col-12) and small (col-sm-12) column breakpoints.
Replace your HTML with this (Bootstrap 5):
<div class="row gy-3 position-absolute top-50 start-50 translate-middle w-100">
<div class="col-12 col-sm-12 col-md-4 text-center">
<button onClick="window.location.href='dothraki.html';"> Dothraki</button>

</div>
<div class="col-12 col-sm-12 col-md-4 text-center">
<button onClick="window.location.href='sindarin.html';">Sindarin</button>
</div>
</div>
And then replace your button CSS with this (removing the button positioning):
button {
font-family: 'Almendra SC', serif;
transition: 0.5s;
padding: 15px 60px;
text-decoration: none;
font-size: 2vw;

}
Also, I recommend you replace your buttons with Anchor tags if they are only going to take the user to a page.

76383962 | 76385414 | I have a list of activities that is generated dynamically with javascript in the following manner:
const renderList = (activities) => {
const display = document.getElementById('task-list-display');
activities.forEach((activity) => {
console.log(activity);
display.insertAdjacentHTML('beforeend', `
<li class="task-item draggable" draggable="true">
<div class="chk-descr">
<input data-a1="${activity.index}" type="checkbox" name="completed"/>
<p data-b1="${activity.index}" class="description" contenteditable="true">${activity.description}</p>
</div>
</li>
`);
I want to have it be responsive in a way that the items can be rearranged using drag and drop. I am not able, however, to make this work. Previously I had designed the very same app but instead of having the items of the list be inserted using insertAdjacentHTML() I was creating each element using createElement() and then appending it to the corresponding HTML element using appendChild(). The drag and drop functionality on that app was fully functioning. My question is: is there some reason why drag and drop might not work with a dynamically generated list using insertAdjacentHTML?.
Here is all the relevant code:
let activities = [];
const dragstart = (element) => {
element.classList.add('skateover');
};
const dragover = (element, e) => {
e.preventDefault();
element.classList.add('dragover');
};
const dragleave = (element) => {
element.classList.remove('dragover');
};
const drop = (element) => {
const skateover = document.querySelector('.skateover');
element.before(skateover);
repopulateList();
element.classList.remove('dragover');
};
const dragend = (element) => {
element.classList.remove('skateover');
};
const repopulateList = () => {
const listItems = document.querySelectorAll('.draggable');
emptyList();
let i = 0;
listItems.forEach((listItem) => {
listItem.setAttribute('activity', i);
i += 1;
const description = listItem.getElementsByClassName('description')[0].textContent;
const completed = listItem.getElementsByClassName('completed')[0].checked;
const index = listItem.getAttribute('activity');
inputActivity(description, completed, index);
});
};
const inputActivity = (description, completed, index) => {
activities.push({ description, completed, index: parseInt(index, 10) });
};
And in the HTML file:
<ul id="task-list-display"></ul>
| Drag and drop not functioning on dynamically created list | That is not a problem. Here I add the eventlisteners to the unordered list (<ul>). So, the adding, cloning and removing of list items (<li>) is not an issue.
There is no problem in using methods like insertAdjacentHTML(). In this example I just use cloneNode() for cloning the node that is moved and then insertBefore() to insert the cloned node before the list item that is hovered/dropped on.
const aktivities = [{
index: 1,
description: "Item 1"
},
{
index: 2,
description: "Item 2"
},
{

description: "Item 3"
}
];

<input data-a1="${activity.index}" type="checkbox" name="completed"/>
<p data-b1="${activity.index}" class="description" contenteditable="true">${activity.description}</p>
</div>
</li>
`)
});

let original = document.querySelector(`li[data-id="${e.dataTransfer.getData("text/plain")}"]`);
let clone = original.cloneNode(true);
let target = e.target.closest('li.task-item');

Type 'unknown' is not assignable to type 'string'.
For some reason if my defaultValue input is undefined, it will give this error, even though I do a truthy check.
How would I fix this without using an '' as the defaultValue?
| Typescript returns unknown for generic only on undefined input | If you don't pass in a defaultValue argument to getEnvVariable, then the compiler has no inference site for the generic type parameter T. So inference fails, and T falls back to its constraint, which is implicitly the unknown type.
If you'd like T to fall back to something else, you can use a default type argument as shown here:
function getEnvVariable<T = string>(
// default type arg ----> ^^^^^^^^
name: string, defaultValue?: T
): T | string { /* impl */ }
Then you'll get the desired behavior when defaultValue isn't supplied:
const unsuppliedDefault = getEnvVariable("Y");
// const unsuppliedDefault: string
without changing the behavior when it is:
const suppliedDefault = getEnvVariable("X", Math.random());
// const suppliedDefault: string | number

76382016 | 76382233 | Task: to create a tournament bracket according to the double elimination system. For the upper bracket, there were no problems, since the teams that won in the first round meet in the second, and so on. But for the lower bracket, in addition to the games among the losers in the first round, you need to add games among the losers in the second round of the upper bracket.
For example, given an array of lower bracket games:
const games = [
{ id: 1, home_name: "Team 1", visitor_name: "Team 3", home_score: 1, visitor_score: 0, round: 2 },
{ id: 2, home_name: "Team 6", visitor_name: "Team 7", home_score: 1, visitor_score: 0, round: 2 },
{ id: 3, home_name: "Team 1", visitor_name: "Team 6", home_score: 0, visitor_score: 1, round: 3 },
{ id: 4, home_name: "Team 4", visitor_name: "Team 5", home_score: 1, visitor_score: 0, round: 3 },
{ id: 5, home_name: "Team 6", visitor_name: "Team 4", home_score: 1, visitor_score: 0, round: 4 },
];
To display the structure of the lower bracket, you need to get the following object:
{
name: "Team 6",
children: [
{
name: "Team 4",
children: [{ name: "Team 4" }, { name: "Team 5" }],
},
{
name: "Team 6",
children: [
{ name: "Team 1", children: [{ name: "Team 1" }, { name: "Team 3" }] },
{ name: "Team 6", children: [{ name: "Team 6" }, { name: "Team 7" }] },
],
},
],
}
In the parent object "Team 6" is the winner of the lower bracket, this can be understood from the last (4) round played between Team 4 and Team 6, in turn Team 4 is determined by the game between Team 4 and Team 5 in round 3.
What the lower bracket will look like for these games:
How to get such an object from the games array? The number of games may vary depending on the number of teams.
| Recursive object construction | You could use a plain object to collect subtrees keyed by the winning team's name, starting out with an empty object. Then iterate the games in order of round and look up the two team's subtrees from that object (with a default {name} object). Then construct the children property from that and wrap it into a new root node. Register that node in the collection of subtrees.
Finally retain the last object that was created which will have the whole tree:
function getTree(games) {
// Ensure the data is sorted by round -- if this is already ensured by caller, then you can drop this statement:
games = [...games].sort((a, b) => a.round - b.round);
const nodes = {}; // This will collect the subtrees, keyed by the winning team's name.
let winner;
for (const {home_name, home_score, visitor_name} of games) {
const name = home_score ? home_name : visitor_name;
winner = nodes[name] = {
name,
children: [
nodes[home_name] ?? { name: home_name },
nodes[visitor_name] ?? { name: visitor_name }
]
};
}
return winner;
}
const games = [
{ id: 1, home_name: "Team 1", visitor_name: "Team 3", home_score: 1, visitor_score: 0, round: 2 },
{ id: 2, home_name: "Team 6", visitor_name: "Team 7", home_score: 1, visitor_score: 0, round: 2 },
{ id: 3, home_name: "Team 1", visitor_name: "Team 6", home_score: 0, visitor_score: 1, round: 3 },
{ id: 4, home_name: "Team 4", visitor_name: "Team 5", home_score: 1, visitor_score: 0, round: 3 },
{ id: 5, home_name: "Team 6", visitor_name: "Team 4", home_score: 1, visitor_score: 0, round: 4 },
];
console.log(getTree(games));

Moving the value is not an option since it have to make multiple threads

76383571 | 76383624 | I wanted to perform a mathematical function on each unique item in a data frame dynamically.
Normally to perform a mathematical function, we use mutate statement and create a column and perform the mathematical function manually by writing mutate statement after mutate statement.
Which is feasible on a few columns. But what if I have 100 columns and I have to perform 2-5 mathematical function, For example: one would be 20% increase on the initial number, The other one would be to divide the initial number by 2 on each column and keep the original column as is.
Is this possible in R other than writing mutate statement for each specific item?
The data frame I am working with is:
structure(list(`Row Labels` = c("2023-03-01", "2023-04-01", "2023-05-01",
"2023-06-01", "2023-07-01", "2023-08-01", "2023-09-01", "2023-10-01"
), X6 = c(14, 16, 14, 11, 9, 9, 11, 11), X7 = c(50, 50, 50, 50,
50, 50, 50, 50), X8 = c(75, 75, 75, 75, 75, 75, 75, 75), X9 = c(100,
100, 100, 100, 100, 100, 100, 100), X11 = c(25, 25, 50, 75, 125,
200, 325, 525), X12 = c(50, 50, 100, 150, 250, 400, 650, 1050
)), class = c("tbl_df", "tbl", "data.frame"), row.names = c(NA,
-8L))
For individual cases this code would suffice:
library(readxl)
library(dplyr)
Book1 <- read_excel("C:/X/X/X- X/X/Book1.xlsx",sheet = "Sheet6")
dput(Book1)
Book1 <- Book1 %>%
mutate(`X6 20%` = X6*1.20) %>%
mutate(`X6 by 2`= X6/2)
I was thinking of running this through a loop but then selection of columns to multiple becomes a problem as we have to specify the column name in mutate statement, which I believe would not be possible here right.
Can anyone let me know if this can be achieved in a simple approach?
The expected output is given below:

76382036 | 76382266 | I have a random seed set at the start of my run for reproducibility. But there are a few sub-functions (e.g. rando) that also use random numbers. If I used a different random number seed just for those, it affects the random seed outside of the function. Is it possible to set the random seed and use it only locally inside the function and the random state outside the function does not get affected? I believe I can always get the random state, save it and restore it. Would there be an easier option? I showed an example below.
import numpy as np
def rando():
np.random.seed(420)
np.random.randint(1, 100)
np.random.randint(1, 100)
return None
np.random.seed(69)
for n in range(3):
np.random.randint(1,100) # outputs : 55,76,74
for n in range(3):
np.random.randint(1,100) # outputs : 91,56,21
Is it possible to make the function below also output the same thing?
np.random.seed(69)
for n in range(3):
np.random.randint(1,100) # outputs : 55,76,74
rando()
for n in range(3):
np.random.randint(1,100) # would like it to output : 91,56,21
| Python Local random seed | That's why there are numpy random generators and that is why they recommend using that. Just define one generator for each instance, e.g.:
def rando(rng):
print('function')
print(rng.integers(1, 100))
print(rng.integers(1, 100))
print('end of function')
return None
rng1 = np.random.default_rng(69)
rng2 = np.random.default_rng(420)
for n in range(3):
print(rng1.integers(1, 100)) # outputs : 6,58,67
rando(rng2) # outputs 62, 77
for n in range(3):
print(rng1.integers(1, 100)) # would like it to output : 53,78,86
yielding:
6
58
67
function
62

var data = { "count": 2 }

76381732 | 76382299 | I have a problem, where I have to find the optimal cost of 3 given motor.
Motor 1 has a range of 100 - 300
Motor 2 has a range of 400 - 1000
Motor 3 has a range of 50 - 250
They have a target value of 600
Motor 1 price is 5000
Motor 2 price is 5500
Motor 3 price is 5250
The equation looks like this:
Cost = Motor1 * 5000 + Motor2 * 5500 + Motor3 * 5250.
And a very important part, NOT every motor needs to run.
I have a python code, that can calculate it, but I can give it to it that not every motors needs to be inclued.
Here is the code:
from pulp import LpProblem, LpVariable, LpMinimize
def find_lowest_cost():
# Define the problem
problem = LpProblem("Motor Optimization", LpMinimize)
# Define the decision variables
x = LpVariable("Motor1", lowBound=100, cat='Integer') # Power of motor 1
y = LpVariable("Motor2", lowBound=0, cat='Integer') # Power of motor 2
z = LpVariable("Motor3", lowBound=50, cat='Integer') # Power of motor 3
# Define the objective function (cost)
problem += x * 5000 + y * 5500 + z * 5250
# Define the constraints
problem += x >= 100 # Motor 1 lower bound
problem += x <= 300 # Motor 1 upper bound
problem += y >= 350 # Motor 2 lower bound
problem += y <= 1000 # Motor 2 upper bound
problem += z >= 50 # Motor 3 lower bound
problem += z <= 250 # Motor 3 upper bound
problem += x + y + z == 500 # Total power constraint
# Solve the problem
problem.solve()
# Retrieve the optimal solution
lowest_cost = problem.objective.value()
best_combination = (x.value(), y.value(), z.value())
return lowest_cost, best_combination
cost, combination = find_lowest_cost()
print("Lowest cost:", cost)
print("Motor combination:", combination)
I tried to add 'or' to the "Define the Constraints' part, but it did not help
problem += x >= 100 or x ==0 # Motor 1 lower bound
problem += x <= 300 # Motor 1 upper bound
problem += y >= 350 or y == 0 # Motor 2 lower bound
problem += y <= 1000 # Motor 2 upper bound
problem += z >= 50 or z == 0 # Motor 3 lower bound
problem += z <= 250 # Motor 3 upper bound
problem += x + y + z == 500 # Total power constraint
So my Questions is, how to implement that 'OR' into my code.
Thank you in advance
| How to put 'or' into contraints in Pulp in python | I make some assumptions:
Continuous power of motors, not integral
Observe the minima in your variable bounds, not the redundant and inconsistent constraints added later
Use 500 as a target, not 600
You need binary selection variables, like this:

powers = (
LpVariable('Motor1', cat=LpContinuous, upBound=300),
LpVariable('Motor2', cat=LpContinuous, upBound=1000),
LpVariable('Motor3', cat=LpContinuous, upBound=250),
)
used = LpVariable.matrix(name='MotorUsed', cat=LpBinary, indices=range(len(powers)))
problem = LpProblem(name='Motor_Optimization', sense=LpMinimize)
problem.objective = lpDot(powers, (5000, 5500, 5250))
problem.addConstraint(name='target', constraint=lpSum(powers) == 500)
for power, power_min, use in zip(
powers,
(100, 0, 50),
used,
):
problem.addConstraint(power >= power_min*used)
problem.addConstraint(power <= 1000*used)
problem.solve()
combination = [p.value() for p in powers]
print('Lowest cost:', problem.objective.value())
print('Motor combination:', combination)
Result - Optimal solution found

76385395 | 76385443 | I am creating a simple search bar element in React JSX. I'm trying to render a list of elements that include whatever is in a search query. I basically take an array of all the elements and then I use .filter() function to find everything that includes the query. After that I use .map() function to loop through the results and render elements for each object. I needed to create two different functions for two different datasets as one is an array deeper.
<ul>
{
this.state.searchQuery &&
this.props.searchDB.projects.filter((project)=> {
if (this.state.searchQuery === '' || this.state.searchQuery === null) {
return project;
} else if (project.projectName.toLowerCase().includes(this.state.searchQuery.toLowerCase())) {
return project;
} else {
return null
}
}).map((project, index) => {
//THIS WORKS AS EXPECTED
return(
<li key={'project_' + index}>
{index + '_' + project.projectName}
</li>
)
})
}
{
this.state.searchQuery &&
this.props.searchDB.mentions.forEach((mentionYear) => {
mentionYear.filter((mention) => {
if (this.state.searchQuery === '' || this.state.searchQuery === null) {
return mention
} else if (mention.mentionTitle.toLowerCase().includes(this.state.searchQuery.toLowerCase())) {
return mention
} else {
return null
}
}).map((mention, mentionIndex) => {
console.log(mention.mentionTitle)
//THIS LOGS DATA AS IT SHOULD BUT DOESN'T RENDER ELEMENTS
return(
<li key={'project_' + mentionIndex}>
{mentionIndex + '_' + mention.mentionTitle}
</li>
)
})
}
)
}
</ul>
The first function works fine and returns a element as it should. For some reason the second one does not and it doesn't return any element at all, even though it is basically the same code. Strange is that the data is there, I can log it from the map function and I can see that it is filtered properly. Can someone explain to me what's wrong? I tried quite a lot of possibile mistakes I could have made but I didn't find anything.
| What could be causing my second React JSX function to fail to return elements, despite properly filtered data? | The second version never does anything with the result of .map(). It's invoked inside a forEach() callback, but its result is discarded. Contrast that to the first version where the result of .map() is part of the JSX and rendered.
Don't use forEach() for this. If the intent is that the .forEach() iteration should produce a result just like in the first version, then what you want isn't forEach(). What you want is .map().
For example:
{
this.state.searchQuery &&
this.props.searchDB.mentions.map((mentionYear) => {
return mentionYear.filter((mention) => {
// etc.
}).map((mention, mentionIndex) => {
// etc.
});
})
}
Basically, repeat the same pattern/structure you already know works when iterating over a collection in JSX to produce a rendered result.

How should I fix it?
| Is there a way to get the key at a specified position? | First off, you probably shouldn't do this, because this is not how dictionaries were intended to be accessed.
But if you really need to do this, probably the most straightforward way is to get the list of keys from the dictionary, and then access the dictionary using the first key.
Something like:
list_of_keys = [key for key in Hobbies.keys()]
key_of_interest = list_of_keys[0]
value_of_interest = Hobbies[key_of_interest]
Or as a one-liner:
value_of_interest = Hobbies[[key for key in Hobbies.keys()][0]]
This may also work, but I'm not sure if the order of values is guaranteed the same way the order of keys is. It probably is, but I can't say for sure:
value_of_interest = [value for value in Hobbies.values()][0]

76383370 | 76383691 | I've been learning Vue 3 for the past month or so and have gotten quite far but I can't fix this no matter what I've tried. I know I'm losing reactivity but I can't figure out how and it's driving me nuts. I am using the Composition API and script setup with a simple Pinia store. I created a github repo for it here: https://github.com/thammer67/vue3-reactivity-problem
I have a view (ProjectsView.vue) of project elements that loops through a pinia store array of projects using v-for and passing the array object as a prop. ProjectsView.vue uses a hidden form component (ProjectForm.vue) that I use for adding new projects. Each project in the loop is another component (ProjectItem.vue) with a click handler to a route that loads ProjectDetail.vue. ProjectDetail.vue has a click handler that also uses ProjectForm.vue for editing the item.
Everything works great.

I have also tried the regex with .*key[0-9A-Za-z_]{18}.*, tried to escape - as \\- but it doesn't seems to be working as well.
| Elastic Search Regex are not working as expected | You need to run the regexp query against the content.keyword field
curl -XGET 'https://localhost:9200/_search?pretty' -H 'Content-Type: application/json' -H 'Authorization: Basic redacted' -k -d '{
"query": { "regexp": { "content.keyword": "key[0-9A-Za-z_]{18}" } }
}'
PS: easier to test and provide feedback with real content and real queries ;-)

76380607 | 76382427 | I have this situation:
I'm building a .net Maui smartphone sports app that grabs a list of latitude and longitude (new Location class) of a running activity and draws a line (polyline) in the map to display the route. I can grab the list of exercises from the database and I can draw a polyline in the map, the problem is that I can't do both together because I don't know how to databind the Map functionalitys in my ViewModel class.
Here is my xaml code for the ExercisePage.xaml:
<?xml version="1.0" encoding="utf-8" ?>

As you can see I have my map name declared as routeMap and the first location just to start in somewhere. I also has my model and viewmodel declared for DataBinding of the exercise list in the CarouselView. The tap feature works fine and take me to a new view called ExerciseDetailsPage.
This is the code behind ExercisePage.xaml.cs
using DoradSmartphone.Models;
using DoradSmartphone.ViewModels;
using Microsoft.Maui.Controls.Maps;
using Microsoft.Maui.Maps;
namespace DoradSmartphone.Views;
public partial class ExercisePage : ContentPage
{
public ExercisePage(ExerciseViewModel exerciseViewModel)
{
InitializeComponent();
BindingContext = exerciseViewModel;
}
private void OnTapGestureRouteUpdate(object sender, EventArgs e)
{
var route = new Polyline
{
StrokeColor = Colors.Red,
StrokeWidth = 12,
Geopath =
{
new Location(38.70061856336034 , -8.957381918676203 ),

}
};
routeMap.MoveToRegion(
MapSpan.FromCenterAndRadius(
new Location(38.93479161472441, -8.865352563545757), Distance.FromMiles(1)));
// Add the polyline to the map
routeMap.MapElements.Add(route);
}
}
If I change the actual tap functionality to this tap event, I can drawn any line and other stuffs with in the Map because I can read the map name defined in the xaml code. But in this codebehind class I can't reach my ViewModel, Services or Model class.

This class inherits the BaseViewModel that inherits ObservableObject and has some common properties for all others classes. In the ExerciseViewModel I have my RelayCommand related to the tap feature that grabs the exercise object and add the route, but I cant access the routeMap object. I've tried also to declare a Map class in my viewmodel class, but I get the error all the time that I can't create a instance of a static class.
This is my MauiProgram.cs just in case there's something wrong:

using DoradSmartphone.ViewModels;
using DoradSmartphone.Views;
namespace DoradSmartphone;
public static class MauiProgram

Thank you in advance!
| .Net Maui Google Maps Polyline drawning route feature | unfortunately, MapElements is not a bindable property. However, you can work around that in a couple of ways
for example, create a public method in your VM that returns the route data
public Polyline GetRouteData()
{
var polylines = new Polyline
{
StrokeColor = Colors.Red,
StrokeWidth = 12,
};
foreach(var route in routes)
{
polylines.Geopath.Add(route);
}
return polylines;
}
then in your code behind, first create a class reference to the VM
ExerciseViewModel ViewModel;
public ExercisePage(ExerciseViewModel exerciseViewModel)
{
InitializeComponent();
BindingContext = ViewModel = exerciseViewModel;
}
then your code behind can get the data from the VM that it needs to update the map
routeMap.MapElements.Add(ViewModel.GetRouteData());

76385151 | 76385493 | In column X are those variables that will have values in each column j, in this case only U1, X4 and U2 have values, the rest of the variables belonging to the list ['B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'] will all have their values 0
#example matrix
new_matrix = [[ 'C', 'X', 'B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'],
[ 0.0, 'U1', 8, 2.0, 1.0, -1.0, 0, 0, 1.0, 0],
['+M', 'X4', 2, 1.0, 1.0, 0, 1.0, 0, 0, 0],
['+M', 'U2', 8, 1.0, 2.0, 0, 0, -1.0, 0, 1.0]]
variables = ['X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2', 'B'] #select the first row (only variables)
variables_j_col_values = [[variables.pop(variables.index('B'))] + variables, []] # --> ['B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2']
The problem with this is that I need create the following matrix of values of the variables (without using libraries) where I would have the following:
variables_j_col_values = [['B', 'X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2'],
[ 0 , 0, 0, 0, 2, 0, 8, 8], #column new_matrix[][2]
[ 0 , 0, 0, 0, 1.0, 0, 2.0, 1.0], #column new_matrix[][3]
[ 0 , 0, 0, 0, 1.0, 0, 1.0, 2.0], #column new_matrix[][4]
[ 0 , 0, 0, 0, 0, 0, -1.0, 0], #column new_matrix[][5]
[ 0 , 0, 0, 0, 1.0, 0, 0, 0], #column new_matrix[][6]
[ 0 , 0, 0, 0, 0, 0, 0, -1.0], #column new_matrix[][7]
[ 0 , 0, 0, 0, 0, 0, 1.0, 0], #column new_matrix[][8]
[ 0 , 0, 0, 0, 0, 0, 0, 1.0], ] #column new_matrix[][9]
After create the variables_j_col_values, go replacing the values of the rows (except for row 0 of the variables_j_col_values array because it is a header) in the string inside funcion_obj_z
The logic would be to use a loop that goes through the rows, and does a
.replace(new_matrix[][n], this_element)
funcion_obj_z = 'Z = 3 * X1 + 2 * X2 + 0 * X3 + 0 * X4 + 0 * X5 + M * U1 + M * U2'
In this way, using said string as an expression, it would obtain these prints in the console if it printed the value of j_func in each j iteration. These would be the desired correct output:
#for loop, print the j string replacement the values in the string
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 2 + 0 * 0 + M * 8 + M * 8' #iteration 1
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 1.0 + 0 * 0 + M * 2.0 + M * 1.0' #iteration 2
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 1.0 + 0 * 0 + M * 1.0 + M * 2.0' #iteration 3
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 0 + 0 * 0 + M * -1.0 + M * 0' #iteration 4
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 1.0 + 0 * 0 + M * 0 + M * 0' #iteration 5
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 0 + 0 * 0 + M * 0 + M * -1.0' #iteration 6
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 0 + 0 * 0 + M * 1.0 + M * 0' #iteration 7
j_func = 'Z = 3 * 0 + 2 * 0 + 0 * 0 + 0 * 0 + 0 * 0 + M * 0 + M * 1.0' #iteration 8
| Replacing values in a string expression based on a matrix and iterating over columns | Albeit an ugly solution, this should give you the transformation you need:

['+M', 'U2', 8, 1.0, 2.0, 0, 0, -1.0, 0, 1.0]]
variables = ['X1', 'X2', 'X3', 'X4', 'X5', 'U1', 'U2', 'B']
# create empty matrix
variables_j_col_values = [[0 for _ in range(len(variables))] for _ in range(len(new_matrix[0])-1)]
# replace first row with sorted variables based on new_matrix headers
variables_j_col_values[0] = sorted(variables, key=lambda x: new_matrix[0].index(x))
# loop over all value rows
for row in new_matrix[1:]
# get correct column in variables_j_col_values based
col = variables_j_col_values[0].index(row[1])

76382456 | 76383719 | I wanted to write a query that would allow me to calculate deviations by the number of created orders.
Task: the query should look back 7 days and based on this data build a minimum allowable threshold (MAT). If the number of orders for a minimum period of time (5 minutes) is less than MAT, then an alert will be generated.
Features: The number of orders directly affects the time of day and seasonality.
Having searched the Internet, I found information about so-called Poisson distribution, and tried to apply it to the problem, but it didn't work.
In prometheus there are such functions as day_of_week(), avg_over_time() and stddev_over_time.
From what I was able to do:
The difference between the number of orders in the last 5 min.
sum(delta(my_search_counter{service_name="car.book.v1"}[5m])
Five-minute average time variation over the last 30 minutes with a resolution of 5 minutes
avg_over_time(sum(delta(my_search_counter{service_name="car.book.v1"}[5m]))[1w:5m])
Mean square deviation:
stddev_over_time(sum(delta(my_search_counter{service_name="car.book.v1"}[5m]))[1w:5m])
This is where I'm stuck and can't figure out how to build a proper query. Maybe there is another way, simpler, but I haven't found it.
I tried to combine these queries with each other using addition, subtraction and division.
| How can i create a deviations query? | I'm not sure what statistics is this, and how adequate this is as a threshold, but here is query you described.
sum(increase(my_search_counter{service_name="car.book.v1"}[5m]))
< sum(increase(my_search_counter{service_name="car.book.v1"}[5m] offset 1w))
- stddev_over_time(sum(increase(my_search_counter{service_name="car.book.v1"}[5m] offset 1w))[1d:5m])
It returns value if number of oreder over last 5 minutes is less then number of orders over same 5 minutes 1 week ago minus standart deviation of orders number over 24 hours presiding current moment 1 week ago.
You might need to play a little with multiplier for stddev part, to get a reasonable percent of alerts.

76383416 | 76383740 | In a Java 17 project, I have a collection of objects with a String field propGroupName representing the group this object belongs to and a Boolean field propValActive representing whether this object is flagged as active internally.
I want to aggregate these objects by the string field into a Map<String, Boolean> with the key being the String field and the Boolean being false if all the booleans in the group are false and true if 1 or more of the booleans in the group are false. I have a working implementation with a simple for loop, but I want to know if there is a way to do this grouping through the Java Stream API, preferably in a way that short circuits? The goal is that I want to know of every group whether there are any objects in that group flagged as active.
I currently have this implementation which doesn't use the Streams API and doesn't short circuit:
public Map<String, Boolean> determineActiveGroups(
HashMap<String, PropertyValueDefinitionGroupView> standardPvdgMap) {
Map<String, Boolean> activeGroupsMap = new HashMap<String, Boolean>();
for (PropertyValueDefinitionGroupView pvdgView : standardPvdgMap.values()) {
if(pvdgView.getPropGroupOid() == null) {
continue;
}
activeGroupsMap.putIfAbsent(pvdgView.getPropGroupName(), false);
if(pvdgView.getPropValActive()) {
activeGroupsMap.put(pvdgView.getPropGroupName(), true);
}
}
return activeGroupsMap;
}
I have a different bit of code somewhere else that does something similar, but it retains the lists, and I managed to adapt something similar for what I need but I don't know what predicate I can use to finish it with. I assume it's going to use anyMatch, but I have no idea how to integrate it:
Map<String, Boolean> activeGroups = standardPvdgMap.values().stream()
.collect(Collectors.groupingBy(PropertyValueDefinitionGroupView::getPropGroupName, ???????));
| Group list of objects into Map with value being true if any object in group has field set as true using Java stream API | groupingBy is such a powerful collector :
public Map<String, Boolean> determineActiveGroups(Map<String, PropertyValueDefinitionGroupView> standardPvdgMap) {
return standardPvdgMap.values()
.stream()
.filter(pvdgView -> pvdgView.getPropGroupOid() != null)
.collect(Collectors.groupingBy(
PropertyValueDefinitionGroupView::getPropGroupName,
Collectors.mapping(
PropertyValueDefinitionGroupView::getPropValActive,
Collectors.reducing(false, (a, b) -> a || b))
));
}
The trick is knowing that you can apply further collectors on the downstream. In this case I map to the flag, and then reduce the flags using the logical or.

76381701 | 76382431 | I need to have a MS Word Macro check upon file exit or file close, that certain specified text fields (legacy form fields, not content control) are empty.

76383035 | 76383754 | I am facing an issue with Typescript generics.
I have a function which must be called with a type and some attributes depending on this type.
Typescript does not manage to infer the type of attributes when inside an if guarding the type to TYPES.ME:
enum TYPES {
ME = 'me',
YOU = 'you'
}
type Attributes<T extends TYPES> = T extends TYPES.ME ? {keys: true} : {hat: true}
const func = <T extends TYPES>(type: T, attr: Attributes<T>) => {
if(type === TYPES.ME) {
attr.keys // error Property 'keys' does not exist on type '{ keys: true; } | { hat: true; }'
}
}
Playground link
I would like to have your opinions on this matter and see if there is a nice workaround.
Cheers!
| Type inference on function parameters with nested generics? | Currently, TypeScript is unable to re-constrain generic type parameters as a result of control flow analysis. Inside the body of func(type, attr), you check that type === Types.ME. This can narrow the type of type from T to something like T & Types.ME. But it cannot do anything to T itself. The type parameter T stubbornly stays the same; it is not constrained to Types.ME. And thus the compiler cannot conclude that attr is of type Attributes<Types.ME>.
And it is technically correct for the compiler to refuse to change T. That's because, while individual values like type can only be one thing at a time, a type argument like T can be a union. Indeed, you can call func() with a T equal to the full Types.ME | Types.YOU union, like so:
func(
Math.random() < 0.999 ? Types.ME : Types.YOU,
{ hat: true }
) // compiles without error
If you inspect that, you'll see that T is inferred as Types (the full union of Types.ME | Types.YOU, and therefore attr is allowed to be {hat: true} even in the 99.9% likely event that type is Types.ME.
There is a longstanding open feature request at microsoft/TypeScript#27808 which asks for a way to say "T will be exactly one of Types.ME or Types.YOU; it cannot be a union". And then, maybe inside the function body, checking type === Types.ME would allow T itself to be constrained to Types.ME, and things would work as expected. And presumably the call with Math.random() < 0.999 would be rejected.
But for now it's not part of the language.
You might consider taking the approach where instead of having func be generic, you make it similar to an overloaded function, where it has one call signature per member of Types. You can write that as a function with a rest parameter whose type is a discriminated union of tuple types, and the compiler will treat it as such inside the function body.
Perhaps like this:
type FuncArg =
[type: Types.ME, attr: { keys: true }] |
[type: Types.YOU, attr: { hat: true }];
const func: (...args: FuncArg) => void = (type, attr) => {
if (type === Types.ME) {
console.log(attr.keys) // this works
}
}
And now you can't make the invalid call:
func(
Math.random() < 0.999 ? Types.ME : Types.YOU,
{ hat: true }
) // error, type 'Types.ME' is not assignable to type 'Types.YOU'
Everything works because now type and attr are bound together as desired in FuncArg; it's like imagining T were constrained to be just one member of Types at a time, and walking through the possibilities. Note that FuncArg could, if necessary, be computed from the Attributes type given in the question, or from another mapping interface, but that is out of scope for the question as asked.

76383892 | 76385502 | I'm developing a car rental automation system in SQL, and I'm seeing unwanted data in my table that I've received and constantly updated. The query I need to write is as follows: 'Write a query that retrieves information about the last rented car for customers who have rented cars with the feature of a sunroof at least once.' I've been struggling with it for hours and couldn't solve it. Can you help me?
select * from car a
where exists(
select * from car a2
inner join customer m on m.customer_id=a2.customer_id
inner join rent k on k.customer_id=m.customer_id
inner join car_rent ak on ak.rent_id=k.rent_id
inner join package_package_option pk on pk.package_id=a2.package_id
where pk.option_id=2 and a.rent_sell=1
group by ak.date
having ak.date = max(ak.date)
| SQL query for last rented car with sunroof feature in car rental system | The solution has two steps:
Identify all customers who have ever rented a car with a sunroof, and
For each such customer, look up the latest rental for each such customer.
The first step is pretty straight forward - Filter the rentals for sunroof and select distinct customer IDs.
The second step can be done a couple of ways. One is to feed the customer IDs into a CROSS APPLY (SELECT TOP 1 ... ORDER BY RentalDate DESC) construct to select the latest rental for each selected customer one at a time. Another is to lookup all rentals for the selected customers, assign sequence numbers using the ROW_NUMBER() window function OVER(... ORDER BY RentalDate DESC), and then filtering for row-number = 1.
Something like (pseudocode):
SELECT *
FROM (
SELECT DISTINCT customer_id
FROM rentals
WHERE has-a-sunroof
AND is-a-rental
) C
CROSS APPLY (
SELECT TOP 1 rental-info
FROM rentals R
WHERE R.customer_id = C.customer_id
AND is-a-rental
ORDER BY R.Rentaldate DESC
) R
or
SELECT *
FROM (
SELECT rental-info,
ROW_NUMBER() OVER(PARTITION BY R.customer_id ORDER BY R.Rentaldate DESC) RowNum
FROM rentals R
WHERE R.customer_id IN (
SELECT DISTINCT customer_id
FROM rentals
WHERE has-a-sunroof
AND is-a-rental
)
AND is-a-rental
) A
WHERE A.RowNum = 1
You might try both to compare performance with large data sets. I recommend also ensuring that you have an index on the rental that includes both customer_id and rental date for best performance.

76382019 | 76382608 | I am trying to read a value from a sensor, BMP280 over SPI on a Raspberry Pi Pico. But I am getting an unexpected value.
I created a new repo based on the rp2040-project-template and modified it to add SPI functionality.
I added these imports:
use embedded_hal::prelude::_embedded_hal_spi_FullDuplex;
use rp_pico::hal::spi;
use rp_pico::hal::gpio;
use fugit::RateExtU32;
Then I setup SPI in the bottom of main function:
let _spi_sclk = pins.gpio2.into_mode::<gpio::FunctionSpi>();
let _spi_mosi = pins.gpio3.into_mode::<gpio::FunctionSpi>();
let _spi_miso = pins.gpio4.into_mode::<gpio::FunctionSpi>();
let mut spi_cs = pins.gpio5.into_push_pull_output_in_state(PinState::Low); // initial pull down, for SPI
let spi = spi::Spi::<_, _, 8>::new(pac.SPI0);
let mut spi = spi.init(
&mut pac.RESETS,
clocks.peripheral_clock.freq(),
10.MHz(), // bmp280 has 10MHz as maximum
&embedded_hal::spi::MODE_0,
);
spi_cs.set_high().unwrap(); // pull up, set as inactive after init
delay.delay_ms(200); // some delay for testing
Then I try to read the ID registry
spi_cs.set_low().unwrap();
let res_w = spi.send(0xd0 as u8); // 0xd0 is address for ID, with msb 1
let res_r = spi.read();
spi_cs.set_high().unwrap();
// check results
match res_w {
Ok(_) => info!("write worked"),
Err(_) => info!("failed to write")
}
match res_r {
Ok(v) => info!("read value from SPI: {}", v),
Err(_) => info!("failed to read SPI")
}
With this code, the SPI read fails. Why is that?
Perhaps it is necessary to set a mode on the sensor, before reading the ID. I can add this code above the read, to set forced mode.
spi_cs.set_low().unwrap();
spi.send(0xf4-128 as u8).expect("failed to send first byte"); // registry 0xf4 with msb 0
spi.send(0x1 as u8).expect("failed to send second byte");
spi_cs.set_high().unwrap();
Now the read of ID registry works, but I get value 255 and not the expected 0x58.
What am I doing wrong?
I have also tried with transfer using this code:
let mut data: [u8; 2] = [0xd0, 0x0];
let transfer_success = spi.transfer(&mut data);
match transfer_success {
Ok(v) => info!("read data {}", v),
Err(_) => info!("failed to read")
}
But I read the values as [255, 255] with this code, not the expected 0x58.
| Read value from SPI on Raspberry Pi Pico using Rust | read() is probably not the function you want to use here; it doesn't acutally perform any bus action but only gives you the byte that was read during the last send().
The function you actually want to use is transfer(). On a full-duplex SPI bus, a "read" action is always also a "write" action, and transfer performs both. Be aware that if you only want to read, you need to write the same amount of zeros, because only the bus master can provide the clock to do anything.
So if you want to write 0xd0, followed by reading a single byte, you need to transfer() the values [0xd0, 0x00]. The same array that you use to put your sent data into transfer() will then contain the received data; most likely [0x00, <data>] (or [0xff, <data>], not sure. Probably 0xff, as you already mentioned that you read a 255).
The implementation of transfer shows how read() is actually supposed to be used:
fn transfer<'w>(&mut self, words: &'w mut [W]) -> Result<&'w [W], S::Error> {
for word in words.iter_mut() {
block!(self.send(word.clone()))?;
*word = block!(self.read())?;
}
Ok(words)
}
Note the block!() here - in embedded, asynchronous calls usually return an error indicating that the operation would block, until it is finished. The block!() macro converts an asynchronous call to a blocking call, which is most likely where your error comes from.
Either way, I would recommend deriving your code from the official example, those are usually pretty good at demonstrating the intended way an object should be used.

The font color does not seem to work but the font size does change.
Also, I do understand that explicit font description is expiring and we should be using the CSS styling. If you could suggest that option,okay to use that option as well.
| Font Color does not update | Using HTML elements and classes is the better option although I do admit some might seem overly complicated.
For my answer, first I give the paragraph a class. Inside of it, I'm aligning the text left and bolding EVERYTHING in it.
Next, spans are by default inline (meaning they show inline with the text, but you don't have control over the spacing). You could also use a div. So every span in the paragraph tag, I'm setting to inline block so I can control the spacing around it while keeping the text inline.
Next each part of the content gets wrapped in its own span.
Since earlier I already set all content to bold, I'm only going to give the title span a margin to the right to space it out and change the font size.
Next for the rest I wrapped that content in another span and changed the color to blue (hex is #Red Green Blue) and I changed the font size also.

1-) Add the following line of code at the beginning of your class:
import { useParams } from 'react-router-dom';
2-) Then add this function above your class (copy it exactly):
export function withRouter(Children){
return(props)=>{
const match = {params: useParams()};
return <Children {...props} match = {match}/>
}
}
3-) Next, change your class definition to this:

76383738 | 76383823 | Novice trying to simplify my jQuery, to avoid repetition
I am a novice with Javascript and jQuery, but have written some code to display a tooltip on a form depending on the answer selected to a dropdown. Right now I am repeating the steps twice:
Once to check the dropdown on page load, in case it has reloaded due to a submission error - in this case, if an answer has been selected to that question, it will persist, and I need the tooltip to remain.
Once to check whenever the dropdown value changes.
The value of the dropdown is a number, so I've used that in the div classes to show the appropriate div. This is the code which is working fine:
$(document).ready(function(){
var service = "";
var otherservice = "";
// Check for select value on page load, in case it has refreshed due to a form error
service = '.v' + $('select#989022_58716pi_989022_58716 option:selected').val();
otherservice = '#form-tooltips div:not('+service+')';
$('#form-tooltips div'+service).show();
$(otherservice).hide();
// Check again for select value, every time that selection changes
$('select#989022_58716pi_989022_58716').on('change', function(){
service = '.v' + $('select#989022_58716pi_989022_58716 option:selected').val();
otherservice = '#form-tooltips div:not('+service+')';
$('#form-tooltips div'+service).show();
$(otherservice).hide();
});
});
//The tooltips for display
$("<div id='form-tooltips'><div class='v1381962'>Tooltip 1</div><div class='v1381965'>Tooltip 2</div></div>").insertAfter(".add-tooltip-after");
What I would like to do is create a function - checkTooltip - so that I do not have to repeat those tooltip instructions the second time. I have tried the following:
$(document).ready(function(){
var service = '';
var otherservice = '';
function checkTooltip({
service = '.v' + $('select#989022_58716pi_989022_58716 option:selected').val();
otherservice = '#form-tooltips div:not("+service+")';
$('#form-tooltips div'+service).show();
$(otherservice).hide();
});
checkTooltip();
$('select#989022_58716pi_989022_58716').on('change', checkTooltip());
});
$("<div id='form-tooltips'><div class='v1381962'>Tooltip 1</div><div class='v1381965'>Tooltip 2</div></div>").insertAfter(".add-tooltip-after");
However this is not working. In the Chrome console, it says Uncaught SyntaxError: Unexpected token ';' on the 5th line. I have tried removing that semicolon but then it gives me Unexpected identifier 'otherservice' instead.
Am I completely misunderstanding how this works or making some kind of syntax error? Many thanks in advance to anyone who can help!
| How can I simplify my jQuery code to avoid repeating instructions? | The syntax is definitely wrong, but in the function definition. It should look like this. No guarantees on whether the functionality is correct.:
$(document).ready(function(){
let service = '';
let otherservice = '';
const checkTooltip = () => {
service = '.v' + $('select#989022_58716pi_989022_58716 option:selected').val();
otherservice = '#form-tooltips div:not("+service+")';
$('#form-tooltips div'+service).show();
$(otherservice).hide();
}
checkTooltip();
$('select#989022_58716pi_989022_58716').on('change', checkTooltip);
});
Note the change in the on.change handler at the end too.
Also its out of scope for your question but 989022_58716pi_989022_58716 probably could be rewritten with a more human-readable id or class.

| getting rid of bold characters in a filename | You can use the PHP iconv function to convert the string from one character encoding to another. In this case, you can try converting the string from UTF-8 to ASCII//TRANSLIT, which will attempt to transliterate any non-ASCII characters into their closest ASCII equivalents.
Here's an example:
function sanitize_string($input_string) {
$sanitized_string = iconv("UTF-8", "ASCII//TRANSLIT", $input_string);
return $sanitized_string;
}
$filename = "4 𝘽𝘼𝙉𝘿𝙀 𝘼𝙉𝙉𝙊𝙉𝘾𝙀 - TV.mp4";

| How to get variable from component for put on the App.js | You want to extend your InputField component to accept a callback function, that can be passed by your app:
export default function InputField({onSubmit}) {
function handleSubmit(e) {
// Prevent the browser from reloading the page
e.preventDefault();
// Read the form data
const form = e.target;
const inputVal = form.myInput.value;
console.log(inputVal);
onSubmit(inputVal)
}
...
}
And in your App you need to pass that callback to your component:
<div className="adress-search">
<InputField onSubmit={handleSearchSubmit} />
</div>
Note: Components are not consumed by calling them like functions.
In your App logic, you'll need another state to hold your search value:
...
const [searchValue, setSearchValue] = useState(null);
const handleSearchSubmit = (val) => {
setSearchValue(val);
}
useEffect(() => {
setLoading(true)
fetch(`https://api.multiversx.com/accounts/${searchValue}/tokens`)
.then(response => response.json())
.then(json => setTockens(json))
.finally(() => {
setLoading(false)
});
console.log(tockens);
}, [searchValue])
...

Hi,
I have a TypeScript project where I am trying to instantiate a class which was the default export of a different package. I am writing my project in ESM syntax, whereas the package it's dependent upon has CJS output. The issue I am running into is that at runtime, when the flow reaches the point of class instantiation I am getting the following error -
new TestClass({ arg1: "Hello, World!" });
^
TypeError: TestClass is not a constructor

new TestClass({ arg1: "Hello, World!" });

class TestClass {

}
}
exports.default = TestClass;
Things work fine if I remove "type": "module" from my package.json. They also work fine if the class is a named export instead of a default export in the dependency's code. Is this a known incompatibility when trying to import CJS into ESM or am I doing something incorrectly here?
Note - If I set "moduleResolution": "nodenext" in my tsconfig.json then the error is generated at compile time itself -

~~~~~~~~~
Found 1 error in src/index.ts:3
| Default class instantiation results in TypeError (ESM/CJS interop) | There are known compatibility issues between CommonJS (CJS) and ECMAScript modules (ESM). In ESM, default exports of CJS modules are wrapped in default properties instead of being exposed directly. On the other hand, named exports are unaffected and can be imported directly.
If you specify "type":
Specifying "module" in package.json makes Node.js treat the .js file as her ESM. Therefore, you must import the module using the ESM import statement. However, if the module you are trying to import is in CJS format, you will run into compatibility issues.
There are several options to fix this.
Access the class through the default property as described above.
import Test from 'package-name';
const TestClass = Test.default;
To avoid problems caused by mixing the two module formats, convert all code to use either ESM or CJS.
Load the CJS module using the Node.js createRequire function.
import { createRequire } from 'module';
const require = createRequire(import.meta.url);
const TestClass = require('package-name');

How to resolve this?
| Extract href from string and again bind the updated data to the element in Angular | I'm not sure to understand all but below might help you :
String character escaping
var testString="<p>some info, email <a href="mailto:[email protected]">[email protected]</a> info </p>";
There is a quote issue : a double-quoted string cannot contain double-quotes unless escaped by the \ character (cf. https://www.w3schools.com/js/js_strings.asp -> Escape Character section)
You may fix this issue by replacing some double quotes by simple quotes :
"<p>some info, email <a href='mailto:[email protected]'>[email protected]</a> info </p>"
Regular expression
var href = datar!.match!(/href="([^"]*)/)![1];
Not sure this is the pattern you need. Try instead :
var href = datar!.match!(/href=\'mailto:([a-z@.]+)'/)![1];
DOM element manipulation
About adding the aria-label attribute to the , you would better go with Angular nativeElement.setAttribute(key, value) native javascript querySelector
(cf. https://indepth.dev/posts/1336/how-to-do-dom-manipulation-properly-in-angular and https://angular.io/guide/property-binding)
Finally I would highly recommend the use of RegExr to test your regular expressions https://regexr.com/7ep0u
as well as jsfiddle.net to test your javascript in a safe environment : https://jsfiddle.net/nkarfgx3/

The Donations one will redirect to Stripe without issue; however, the registration one, if a pricing selected is greater than 0, it will then attempt to initiate a Stripe Checkout.

on both of the views, the Stripe API Javascript is included just above the submit button:
= javascript_include_tag "https://js.stripe.com/v3"
Since I copied the code over from the donations controller, I'm not seeing what my error is.
I haven't updated the success_url yet as I'm trying to first get redirected to Stripe. The name and unit_amount are right now hard coded in case my variables aren't working.
| One instance of Stripe Checkout works, the other gives a Preflight response code of 403 | The code you shared is a simple HTTP redirect server-side in Ruby and shouldn't cause a CORS error in the browser unless your client-side code is making an ajax request instead of a page/form submit.
Alternatively, it's possible your form submission is mis-configured and Rails turns this in a turbo request. Adding data-turbo=false to your form might solve that problem.

What could cause this error ? What is wrong with what I've implemented ?
| Problem passing an async function item as parameter in Rust | I found the answer here: How to bind lifetimes of Futures to fn arguments in Rust
The problem as I understand it is this:
From https://rust-lang.github.io/async-book/03_async_await/01_chapter.html:
Unlike traditional functions, async fns which take references or other non-'static arguments return a Future which is bounded by the lifetime of the arguments
So I had to force the Fut lifetime to be shorter than the input parameters lifetime.
The syntax won't let me simply force this by using Higher Ranked Lifetime bounds (as explained in the answer linked above) so I had to use the pattern proposed there: generate a meta trait linking lifetimes as this:
trait XFn<'a, T, S> {
type Output: Future<Output = ()> + 'a;
fn call(&self, this: T, services: S) -> Self::Output;
}
impl<'a, T: 'a, S: 'a, F, Fut> XFn<'a, T, S> for F
where
F: 'static + Copy + FnOnce(T, S) -> Fut,
Fut: Future<Output = ()> + 'a,
{
type Output = Fut;
fn call(&self, this: T, services: S) -> Fut {
self(this, services)
}
}
Then I can use this trait to constraints lifetime on arguments and Future like this:
fn record_callback<F>(callback: F)
where
for<'a> F: XFn<'a, &'a mut FirstTestComponent, &'a mut Services> + 'static + Copy,
{
}

76383199 | 76383930 | My routes are working and accessing components and loader functions. I'm trying now to pass variable filmsPerPage (which is defined once) to both Home component and the loader function in

}

return defer({
loaderData: loadPosts(null, 1, 12, null)
})
}
The prop filmsPerPage is passing correctly to Home.js component and while it's passing to the loader function, the useLoaderData() in Home.js is returning null which means that although the code in the loader function is working properly, it's not returning a loader object to the component. If I do this in App.js, the useLoaderData() function (in Home.js) will get the data but now the loader function doesn't have the prop:
children: [
{
index: true,
element: <Home {...{filmsPerPage}} />,
loader: loaderHome
},
How could I pass the filmsPerPage prop to the loader function which will then return loader data to Home.js?
| Passing a prop/variable to react router 6 loader function | The loader function isn't returning anything. Perhaps reformatted to a more readable format will make this more apparent:
{
index: true,
element: <Home {...{filmsPerPage}} />,
loader: () => {
loaderHome(filmsPerPage); // <-- not returned!!
},
}
The loader should still return the result of calling loaderHome.
Examples:
{
index: true,
element: <Home {...{filmsPerPage}} />,
loader: () => {
return loaderHome(filmsPerPage); // <-- explicit return in function block
},
}
{
index: true,
element: <Home {...{filmsPerPage}} />,
loader: () => loaderHome(filmsPerPage), // <-- implicit arrow function return
}
You could even rewrite loaderHome to curry, e.g. close over in function scope, the filmsPerPage argument.
export function loaderHome(filmsPerPage) {
console.log(filmsPerPage); --> printing out 12
// Return loader function
return (loaderArgs) => {
return defer({
loaderData: loadPosts(null, 1, filmsPerPage, null);
});
};
}
{

/**
* Perform a {@link MessageGroupStore#expireMessageGroups(long)} with the provided {@link #expireTimeout}.
* Can be called externally at any time.
* Internally it is called from the scheduled task with the configured {@link #expireDuration}.

* Used on startup and when an {@link #expireDuration} is provided, the task for running
* {@link #purgeOrphanedGroups()} is scheduled with that period.

76381843 | 76382973 | I'm importing a .csv file which I'm then modifying using calculated properties in a PSCustomObject.
I'm stuck on one calculation where I'm attempting to lookup a value from a datarow object using one of the .csv values.
We receive data with the supplier Part No and I need to lookup our corresponding Part No.
Would you be able to suggest how best to do this please?
The csv content looks like this:
Vendor Code,Part No,Part Description,Bonded,Quantity,PO No,Vendor Ref
TEZ,ABC1234,Dark Blue,No,50,4378923,ORD089234
TEZ,BBC1256,Orange,No,20,4378923,ORD089234
TEZ,ACD1349,Green,No,10,4378923,ORD089234
The SQL query $SKUs returns this as datarows:
ITEMNO VALUE
TYP-5063 ABC1234
TYP-5037 BBC1256
TYP-8069 ACD1349
So I'm looking to use the 'Part No' field from the .csv file to run a lookup against $SKUs.VALUE and return the matching $SKUs.ITEMNO.
The output .csv will then include a column called 'OUR_SKU' containing the $SKUs.ITEMNO value.
Here is my code so far:
$Files = Get-ChildItem -Path "D:\Imports\Test\INVENTORY_HUB_RECEIPTS"
$ProcessingPath = "D:\Imports\Test\INVENTORY_HUB_RECEIPTS\Processing\"
$UKEntity = "TESTTRG"
$HUB_ID = "TEST"
$SKUs = Invoke-Sqlcmd -ServerInstance "localhost" -Database "XXXX" -Query "SELECT RTRIM(ITEMNO) AS ITEMNO, RTRIM(VALUE) AS VALUE FROM [XXXX].[dbo].[ICITEMO] WHERE OPTFIELD = 'CUSTITMNO' AND VALUE <>''"
foreach ($file in $Files) {
$Content = (Import-Csv -path ($ProcessingPath + $file.Name)) |
Select-Object @{n='HUB_ID'; e={ $HUB_ID }},
@{e={$_.'Part No'}; l='PART_NO'},
@{e={$_.Quantity}; l='QTY_RECEIVED'},
DATE,
@{n='ENTITY'; e={ $UKEntity }},
@{e={$_.'Vendor Ref'.Substring($_.'Vendor Ref'.Length -8)}; l='ORDER_ID'},
@{n='OUR_SKU'; e={ $SKUs | Where-Object {$($_.VALUE) -eq '123ABC'} | Select-Object -ExpandProperty ITEMNO}},
@{n='OUR_SKU_X'; e={ $SKUs | Where-Object {$($_.VALUE) -eq $_.'PART_NO'} | Select-Object -ExpandProperty ITEMNO}}
if ($Content.Count -eq 0) {Remove-Item ($ProcessingPath + $file.Name)} else {$Content | Export-Csv -Path ($ProcessingPath + $file.Name) -Not -Force}
}
I've tried two examples for the new property 'OUR_SKU' this works but is obviously a static value.
The property 'OUR_SKU_X' is my attempt to use the supplied $.'PART_NO' and this currently returns a blank field.
The variable $SKUs does contain data and so does $.'PART_NO'.
I'm thinking it's either a simple syntax error or it's not possible to use $_.'PART_NO' in the script block?
Thanks
Colin
| Powershell - PSCustomObject with Calculated Property | Per comments, inside the where-object scriptblock on the line:
$SKUs | Where-Object {$($_.VALUE) -eq $_.'PART_NO'}
the automatic variable $_ relates to the individual items piped in from $SKUs, which hides the outer $_ from the $Content = (Import-Csv ...) | Select-Object ...
If you want to be able to access the outer $_ inside the where-object you'll need to capture it into a temporary variable like this:
e={ $tmp = $_; $SKUs | Where-Object { $_.VALUE -eq $tmp.PARTNO } | Select-Object -ExpandProperty ITEMNO}}
Here's a cut-down example:
$parts = @"
Vendor Code,Part No,Part Description,Bonded,Quantity,PO No,Vendor Ref
TEZ,ABC1234,Dark Blue,No,50,4378923,ORD089234
TEZ,BBC1256,Orange,No,20,4378923,ORD089234
TEZ,ACD1349,Green,No,10,4378923,ORD089234
"@ | ConvertFrom-Csv
$skus = @"
ITEMNO,VALUE
TYP-5063,ABC1234
TYP-5037,BBC1256
TYP-8069,ACD1349
"@ | ConvertFrom-Csv
$results = $parts | select-object @(
@{l="PART_NO"; e={ $_."Part No" } },
@{l="DESC"; e={ $_."Part Description" } },
@{n='OUR_SKU'; e={ $part = $_; $skus | where-object { $_.VALUE -eq $part."Part No" } | Select-Object -ExpandProperty ITEMNO} }
)
Note the $part = $_; and $_.VALUE -eq $part."Part No" inside the definition of the third calculated property.
The output from the above is:
$results
PART_NO DESC OUR_SKU
------- ---- -------
ABC1234 Dark Blue TYP-5063
BBC1256 Orange TYP-5037
ACD1349 Green TYP-8069

76381780 | 76383057 | I want to visualize a pre-formatted text (with YAML format and indent). It seems that the <|{text}|> markdown pattern and the state representation removes intents from the text, i.e. all becomes a long mashed text. Here is an example output.
version: '3.1' stories: - story: 06a6e2c5e8bd4058b304b4f23d57aa80 steps: - intent: bot_capabilities user: What can you do
Correct is this:
version: '3.1'
stories:
- story: 06a6e2c5e8bd4058b304b4f23d57aa80
steps:
- intent: bot_capabilities
user: What can you do
Is there a way to keep preformatted text especially with indents?
I could not yet find a fitting property for the "text" control. Raw does not seem to solve the issue. If I print the string before assigning it to a state variable, the output format is correct. Therefore, I assume the stripping of empty space happens automatically afterwards.
| How to visualize formatted text without removing empty space? | The most straightforward way is to use an input visual element with multiline property turned on.
main.py:
from taipy.gui import Gui
#with open("file.yaml", "r") as f:
# yaml_text = f.read()
yaml_text = """

stories:
- story: loferum ipsi

<|{yaml_text}|input|multiline|not active|label=Inactive input|>
<|{yaml_text}|input|multiline|not active|label=Inactive white input|id=yaml|>
"""
Gui(page).run()
Here is the result:
The first input is editable
The second is not editable and grey
The third is not editable and white
For the last element, I added a bit of CSS to make the inactive input white:
main.css:
#yaml.Mui-disabled{
color: white !important;
-webkit-text-fill-color: white !important;
}
An issue has been created on GitHub to improve text visual elements directly.

76383189 | 76383961 | I am trying to search a given directory for a specific file, and if that file does not exist I would want the code to say "File does not exist". Currently with os.walk I can get this to work, however this will hit on every single file that isn't the specified file and print "File dos not exist". I know that this is how os.walk functions, but I was not sure if there is a way to make it only print out once if it is found or not found.
Folder structure:
root folder|
|Project Folder
|file.xml
|other files/subfolders
How I would want the code to work is to go inside of "Project Folder", do a recursive search for "file.xml", and once it is found print out once "Found", otherwise prints out once "Not found".
The code is:
def check_file(x): #x = root folder dir
for d in next(os.walk(x))[1]: #if I understand correctly, [1] will be Project Folder
for root, directories, files in os.walk(x):
for name in files:
if "file.xml" not in name:
print("found")
else:
print("File Missing")
If I change the code to
for name in files:
if "file.xml" in name:
print("found")
else:
pass
The code technically works as intended, but it doesn't really do much to help point out if it isn't there, so this isn't a good solution. It would be easier if I was able to give the code a specific path to look in, however as the user is able to place the 'root folder' anywhere on their machine as well as the 'project folder' would have different names depending on the project, I don't think I would be able to give the code a specific location.
Is there a way to get this to work with os.walk, or would another method work best?
| How can I limit os.walk results for a single file? | The glob module is very convenient for this kind of wildcard-based recursive search. Particularly, the ** wildcard matches a directory tree of arbitrary depth, so you can find a file anywhere in the descendants of your root directory.
For example:
import glob
def check_file(x): # where x is the root directory for the search
files = glob.glob('**/file.xml', root_dir=x, recursive=True)
if files:
print(f"Found {len(files)} matching files")
else:
print("Did not find a matching file")

You are looking for a so called Function Import.
This allows you to define custom functions next to the predefined CRUDQ (Create, Read, Update, Delete, Query) functions. This custom function can have custom input parameters and return values as simple types or Complex Types (=Structures/Entities)
As stated also in SAP Help this should be only used if it does not fit into the CRUDQ methods for your entities.

For other approaches, e.g. RESTful ABAP Programming Model (RAP), it would be Actions and Validations but cannot generally be answered without details of the scenario.

76383470 | 76383965 | My project is located here:
D:/WorkSpace/PuzzleApp
but when I am calling
new File(".").getAbsolutePath();
I get:
D:\!Documents\Desktop\.
Why? And how to fix this?
I'm using Eclipse.
| Why by calling new File(".").getAbsolutePath() I get completely different path from my project's location? | When you open File with relative path "." this path is relative to the current process' working directory.
Usually, the process working directory is inherited from the parent process (e.g. if you run your app with Terminal - the current terminal's working directory will be your process' working dir).
Using a relative path inside your application is considered a bad idea because you can not control this process' working directory.
But using an absolute hardcoded path also goes with some problems and can't be called a good practice.
There are several ways to solve the issue:
Use a path relative to some NOT hardcoded absolute path. This absolute path should be externalized to environment variables, properties files, etc.
//Getting the directory path from the external system variable
String myAbsoultePath = System.getenv("LOCAL_STORAGE_DIR");
Use a path relative to your application root. It allows you to READ files even located inside .jar or .war archives.
//This path looks absolute, but the path's root is your project's root
InputStream stream = MyClass.class.getResourceAsStream("/dir/another/file.txt");
But you should understand, that your application won't run inside your IDE project folder. It will be deployed in a production server/user's desktop/android device environment and usually, it is packed in a jar/war/ear/... archive. It means that you won't have access to your src folder or something like this.

This is my closest attempt, yet it weighs to the total population:
figure1 <- ggplot(data = DS, aes(x = X))+ geom_freqpoly(aes(colour = type, y= after_stat(count / sum(count)))) + ...
Its not surprising that this normalizes to the entire dataset, but I wouldnt know how to get it such that it only normalizes to a subset.
Using dput(), I generate the following example dataframe:
DS <- structure(list(X = c(0, -0.01, 0.042944432215413, 0.0431301011419889, 0.042944432215413, 0.0424042102083902, 0.2100000012 , 0.13513333335333), TimePoint = c("early", "early", "late", "mid", "mid", "early", "late", "early")), row.names = c(NA,8L), class = "data.frame")
In which 'X' is the continous value and 'TimePoint' is the factor which can be either 'early', 'mid' or late.
| How can I create a frequency plot/histogram in R using ggplot2 while normalizing to the total of a factor? | One option would be to use e.g. ave() to compute the count per group or Timepoint:
library(ggplot2)
ggplot(data = DS, aes(x = X)) +
geom_freqpoly(
aes(
colour = TimePoint,
y = after_stat(count / ave(count, group, FUN = sum))
)
)
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

76385118 | 76385549 | So I was trying to write a quick Batch file but it only did half the code, so I switched it to PowerShell because I remembered a while back I was able to get it to work and turns out this did work.
My issue is essentially I have a handful of users I want to have access to this "it just closes a program and reopens". They're familiar with Batch files (which I couldn't get to reopen the program) but would not be used to using a PowerShell script and having to right click to run as PowerShell which I'm expecting will cause issues and many of the users to not use the script in the first place.
Is there either something I did wrong on the batch file for it not to reopen or is there a way to change the left click option on the PowerShell(currently left click opens the script in notepad; ideally it would just run as PowerShell on left click)
The code is the same for both PowerShell and CMD copied and pasted directly to.
taskkill /IM ADM.TrayApp.exe /F
Start-Process "C:\Program Files (x86)\athenahealth, Inc\aNetDeviceManager\3.1.4.0\TrayApp\CoreModule\ADM.TrayApp.EXE"
| Powershell/CMD issue |
You cannot use PowerShell's Start-Process directly in a batch file - you'd have to call via powershell.exe, the Windows PowerShell CLI or pwsh, the PowerShell (Core) CLI).
However, as Stephan points out, cmd.exe's internal start command provides similar functionality, so its use should be sufficient in your case (as Stephan notes, some window title enclosed in "..." is needed as the first argument if the executable to launch is enclosed in "..." too; "" will do):
start "" "C:\Program Files (x86)\athenahealth, Inc\aNetDeviceManager\3.1.4.0\TrayApp\CoreModule\ADM.TrayApp.EXE"
It is possible to make PowerShell scripts execute by default when (double-)left-clicked from File Explorer or the desktop, but requires nontrivial setup on each machine:
See this answer.
The linked answer also describes an alternative technique of providing simple companion batch files whose sole purpose is to execute an associated PowerShell script.

What is correct formula or way to get all text content in the above mentioned xpaths ?
| What is the best way to find text content under relatively indistinguishable tags by Selenium-webdriver? | Not very clear what you want: If you want all elements that contain direct text you could use:
/html/body[1]//*[text()[normalize-space()]]
this will return all elements with direct text()-nodes that after filtering unnecessary whitespace, have character-data.
meaning XPath-parts:
// = any descendant; see this info on axes
* = any element
[some filter] = predicate to filter on direct previous node.
[#number] = the position within its siblings. body[1] maybe seems redundant, but can help the XPath-engine not to look any further for other body elements
text() = node of type text
normalize-space() = strips white-space according this rules

76384278 | 76385594 | I'm moving from a SQL Server database to a DB2 database. I'm trying to compare the primary key of the SQL Server database with the DB2 database and if its the same primary key values then do an update if they are not the same do an insert.
My problem is when I use a lookup for the primary key (first four columns) it only returns the first four columns, I need someway of getting the other two columns so I can run a OLE DB command and do the update.
I want to compare the four primary keys columns (FISCAL_YR, LOC_CODE, SYSTEM_ID, SYSTEM_CODE) and see if they exist in the destination table if they do I want to update two other columns (LOC_NAME, ALIAS_NAME) and if they don't match I want to do an insert.
This is what I have for the lookup currently but it matches all the columns I just want to do the first four (FISCAL_YR, LOC_CODE, SYSTEM_ID, SYSTEM_CODE) but output 6 columns (FISCAL_YR, LOC_CODE, SYSTEM_ID, SYSTEM_CODE, LOC_NAME, ALIAS_NAME) to OLE DB Command so I can do an update:
SELECT
FISCAL_YR, LOC_CODE, SYSTEM_ID,
SYSTEM_CODE, LOC_NAME, ALIAS_NAME
FROM
LC1U1.Location_Supertbl1;
This is the update command I want to execute:
UPDATE LC1U1.Location_Supertbl1
SET ALIAS_NAME = UPPER('test')
WHERE FISCAL_YR = ?
AND LOC_CODE = ?
AND SYSTEM_ID = ?
AND SYSTEM_CODE = ?
How do I do this with a Lookup transformation in SSIS?
Thank you.
| How to do a lookup for the four primary keys columns yet output 6 columns to OLE DB Command | I think the issue you're not asking for the columns from the lookup component.
In the UI, you drag lines between the left (Source) and right (Lookup) side. This defines the equality match for the lookup.
What you want to do is check the 2 additional columns in that menu, something like the following image. This will add LOC_NAME and ALIAS_NAME as new columns, after the Lookup Component, into my data flow

76383537 | 76383985 | I want to validate document before it is inserted into the database. I know that I can set static validator, but I would prefer to have a file with the validation schemas that I could modify at any time.
//example schema
const userCreateValidationSchema = {
bsonType: 'object',
required: ['username', 'password'],
properties: {
username: {
bsonType: 'string',
maxLength: 16,
},
password: {
bsonType: 'string',
maxLength: 64,

},
additionalProperties: false,
};
//example document
const document = {

password: "passwd",
};
Then I would do something like validate(document, userCreateValidationSchema).
Thanks for any thoughts.
I have tried looking for the answer in the documentation but unfortunatelly didn't find the solution.
| How can I validate a MongoDB document using a validation schema from a file? | To perform login validation using the npm package Joi :-
npm install joi
Import Joi and Define Validation Schema :-
const Joi = require('joi');
const loginSchema = Joi.object({
email: Joi.string().email().required(),
password: Joi.string().min(6).required(),
});
In the above example, the validation schema requires the email field to be a valid email address and the password field to have a minimum length of 6 characters.
Perform Validation:
Now you can use the validate() method provided by Joi for the validation.
function validateLogin(loginData) {
const { error, value } = loginSchema.validate(loginData);
return error ? error.details[0].message : null;
}
Usage Example:
Here's an example of how you can use the validateLogin() function to validate the login data:
const loginData = {
email: '[email protected]',
password: 'password123',
};
const validationError = validateLogin(loginData);
if (validationError) {
console.log('Login validation failed:', validationError);
} else {
console.log('Login data is valid.');

76384287 | 76385632 | I am using ggplot2 to visualise map-related data. I have coloured regions according to a continuous value, and I would like to add a legend with colors and region names. My own data is a bit cumbersome to share, but I have recreated the scenario with public data (Mapping in ggplot2). The following code creates the included map:
library(ggplot2)
library(sf)
# Import a geojson or shapefile
map <- read_sf("https://raw.githubusercontent.com/R-CoderDotCom/data/main/shapefile_spain/spain.geojson")
ggplot(map) +
geom_sf(color = "white", aes(fill = unemp_rate)) +
geom_sf_text(aes(label = name), size = 2)
Instead of the continuous default legend, I would like to have a legend with names, numbers and colors. Basically, a legend that shows the name and unemp_rate columns of the data with colors matching the map (eg. unemp_rate). Somewhat like the legend of the second included picture (but the colors are not right).
