76387405 | 76387433 | Let's imagine a situation where we have a queue positioned before the seize block, and this queue has the timeout property activated.
In such cases, it is important to note that the seizure queue cannot be reduced to zero. The seize queue always has a minimum capacity of 1. If the seize queue capacity were set to 1, one agent would be taken out of the timeout property of the original queue and placed directly into the seize queue.
This behavior is generally not desirable, particularly when dealing with a large number of agents or running the simulation for extended periods, such as years, to collect the statistics, especially for the timeout property of the original queue.
So how can I avoid having an agent in the seize queue, or is there another way to achieve this?
| Why seize queue cant be zero in AnyLogic | You can manually avoid having agents in the Seize queue by using a Hold block upstream and only releasing agents into the Seize block if its queue is empty.

76382756 | 76385488 | I'm looking to find an efficient method of matching all values of vector x in vector y rather than just the first position, as is returned by match(). What I'm after essentially is the default behavior of pmatch() but without partial matching:
x <- c(3L, 1L, 2L, 3L, 3L, 2L)
y <- c(3L, 3L, 3L, 3L, 1L, 3L)
Expected output:
pmatch(x, y)
[1] 1 5 NA 2 3 NA
One way is to use ave() however this becomes slow and very memory inefficient as the number of groups increases:
ave(x, x, FUN = \(v) which(y == v[1])[1:length(v)])
[1] 1 5 NA 2 3 NA
Can anyone recommend an efficient way to achieve this in preferably (but not mandatory) base R?
Larger dataset for benchmarking:
set.seed(5)
x <- sample(5e3, 1e5, replace = TRUE)
y <- sample(x, replace = TRUE)
| Efficiently match all values of a vector in another vector | A variant in base using split.
split the indices of both vectors by its value. Subset the second list with the names of the first, that both have the same order. Change NULL to NA and bring the lengths of the second list to those from the first. Reorder the indices of the second list by those of the first.
x <- c(3L, 1L, 2L, 3L, 3L, 2L)
y <- c(3L, 3L, 3L, 3L, 1L, 3L)
a <- split(seq_along(x), x)
b <- split(seq_along(y), y)[names(a)]
b[lengths(b)==0] <- NA
b <- unlist(Map(`length<-`, b, lengths(a)), FALSE, FALSE)
`[<-`(b, unlist(a, FALSE, FALSE), b)
#[1] 1 5 NA 2 3 NA
I tried to exchange the part
b <- split(seq_along(y), y)[names(a)]
b[lengths(b)==0] <- NA
with
b <- list2env(split(seq_along(y), y))
b <- mget(names(a), b, ifnotfound = NA)
But it was not faster.
An RCPP version.
Store the indices of the second vector Γn a queue for each unique value in an unordered_map. Iterate over all values of the first vector and take the indices from the queue.
Rcpp::sourceCpp(code=r"(
#include <Rcpp.h>
#include <unordered_map>
#include <queue>
using namespace Rcpp;
// [[Rcpp::export]]
IntegerVector pm(const std::vector<int>& a, const std::vector<int>& b) {
IntegerVector idx(no_init(a.size()));
std::unordered_map<int, std::queue<int> > lut;
for(int i = 0; i < b.size(); ++i) lut[b[i]].push(i);
for(int i = 0; i < idx.size(); ++i) {
auto search = lut.find(a[i]);
if(search != lut.end() && search->second.size() > 0) {
idx[i] = search->second.front() + 1;
search->second.pop();
} else {idx[i] = NA_INTEGER;}
}
return idx;
}
)")
pm(x, y)
#[1] 1 5 NA 2 3 NA
A for this case specialized RCPP version.
Create a vector of the length of the maximum value of the first vector and count how many times a value is present. Create another queue vector of the same length and sore there the indices of the values of the second vector until it has reached the number of the first. Iterate over all values of the first vector and take the indices from the queue.
Rcpp::sourceCpp(code=r"(
#include <Rcpp.h>

76378680 | 76385544 | I'm trying to extract a couple of elements from XML files into an R dataframe but the parent nodes are all named the same, so I don't know how to associate child elements. I'm very new to xml (about 3 hours) so apologies if I use the wrong terminology. I did not find any R-based solutions.
This is the general structure of the xml files:
<Annotations>
<Version>1.0.0.0</Version>
<Annotation>
<MicronLength>14.1593438418</MicronLength>
<MicronHeight>0.0000000000</MicronHeight>
<ObjIndex>1</ObjIndex>
</Annotation>
<Annotation>
<MicronLength>5.7578076896</MicronLength>
<MicronHeight>0.0000000000</MicronHeight>
<ObjIndex>2</ObjIndex>
</Annotation>
</Annotations>
There are many "Annotation" nodes. There are also several other children node names in there but they don't matter as I'm just trying to extract MicronLength and ObjIndex into a dataframe. So I need to either:
Associate and get both elements from within each "Annotation" node
OR
Rename each "Annotation" based on the ObjIndex within (e.g. "Annotation 1", "Annotation 2", etc.) and then get parent name and child element into the df.
I also have several xml files so I want to iterate over each one to eventually create a DF like the example below.
| filename | ObjIndex | MicronLength |
| ------------------ | -------- | ------------- |
| examplefile1(.xml) | 1 | 14.1593438418 |
| examplefile1 | 2 | 5.7578076896 |
| examplefile2 | 1 | 12.6345661343 |
The filenames (with or without extension) will then be str_split into some more columns but I can do that myself.
Much appreciated!

76387121 | 76387471 | I want to center a text vertically such that the highest point of the text and the lowest point of text are on equal distance from the ending div that it is enclosed in.

| How to align text vertically according to the highest point of the text and lowest point? | This can only be done by adding padding at the bottom or Top and this may vary as per different Fonts. I question is why do you want to do this? As anigning center as per your way would further discurb the balance.
Also, The positioning of certain letters, such as "p," "g," "y," and "q," are lower than the center line is due to their design and the rules of typography. These letters have descenders, which are the parts of the letterforms that extend below the baseline.
Descenders are common in lowercase letters and serve to maintain the overall balance and legibility of the text. They allow for differentiation between similar letterforms and help to create a visually pleasing text block.
When aligning text vertically, the descenders are taken into account to ensure proper spacing and balance. By aligning the baseline of the text, which includes the descenders, it maintains the overall visual harmony of the text and prevents the descenders from interfering with the line spacing or overlapping other elements.
In the case of vertically aligning text to the highest point and lowest point, the descenders will naturally make the text appear lower as they extend below the baseline. This is considered the correct alignment for maintaining legibility and preserving the intended design of the typeface.
It's worth noting that the alignment of text can vary depending on the context and the specific design choices made by the typographer or designer. Different fonts may have slightly different alignments, and some artistic or decorative fonts may intentionally deviate from traditional alignment principles for creative purposes.

| Timer isn't dealing with seconds properly | You don't set the limit correctly - you set it directly to the content of the timer, which includes non numeric characters such as ":". When using parseInt on something that isn't all digits, anything after the first non numeric character is discarded. Therefore, by using anything under a minute to test with, limit will be set to 0, as "00:30" would result in 0 from parseInt, as only text from before the colon is used. To fix this, split the text at the colon and convert the minutes into seconds, as shown in the snippet

76383134 | 76385590 | The program runs multiple commands that require sudo privileges (such as sudo dnf update). Since the program should be installed using the go install command, it can't be run as sudo its self without configuration done by the user (afaik).
The program doesn't show the output to the user to keep the output clean. To show that a process is running, it uses a spinner from the spinner library.
Is it possible to do any of these things?
Obtain sudo privileges from within the program
Make the program runnable as sudo, even when installed using go install
Show the output of the sudo command (including the password request) without it being overwritten by the spinner
Here is a shortened version of what I would like my code to do:
package main
import (
"fmt"
"os"
"os/exec"
"time"
"github.com/briandowns/spinner"
)
func main() {
// Spinner to show that it's running
s := spinner.New(spinner.CharSets[14], time.Millisecond*100)
s.Start()
// Somehow execute this with sudo
_, err := exec.Command(os.Getenv("SHELL"), "-c", "dnf update -y").Output()
// Stop the spinner and handle any error
if err != nil {
fmt.Printf("Err: %s", err)
os.Exit(1)
}
s.Stop()
// Finish
fmt.Println("Success")
}
| Is it possible to run a sudo command in go without running the program itsself as sudo | _, err := exec.Command(os.Getenv("SHELL"), "-c", "sudo dnf update -y").Output()
In this exapmle, with adding sudo before the command that you want run as sudo, and after running the program, will ask password for sudo, If you apply this to your example code you can't see password request message, because the spinner graphics will overwrite it, but if you try this without spinner graphics you can see it. Even you don't see the message, if you type your correct password and press enter your commands will work as sudo. With this, you don't need run your application as sudo. I have ran similar commands with using this and they have worked.

76387474 | 76387579 | I am observing this weird behavior when I am raising an integer to the negative power using an np.array. Specifically, I am doing
import numpy as np
a = 10**(np.arange(-1, -8, -1))
and it results in the following error.
ValueError: Integers to negative integer powers are not allowed.
This is strange as the code 10**(-1) works fine. However the following workaround (where 10 is a float instead of integer) works fine.
import numpy as np
a = 10.**(np.arange(-1, -8, -1)
print(a) # Prints array([1.e-01, 1.e-02, 1.e-03, 1.e-04, 1.e-05, 1.e-06, 1.e-07])
Why is it not valid for integers? Any explanation is appreciated.
| Wierd behavior with raising intgers to the negative powers in python | This is happening because the input 10 is an integer.
10**(np.arange(-1, -8, -1))
numpy.arange() is designed such a way that that has to give 10**(np.arange(-1, -8, -1)) integers or nothing since input is an integer.
On the contrary;
a = 10.**(np.arange(-1, -8, -1)
gives results happily as 10.0 is a float
Edit: found an answer to back my point; voted for a duplicate:
Why can't I raise to a negative power in numpy?

As such, I backtracked and attempted to install scalop, like so:
remotes::install_github("jlaffy/scalop")
This is where things start to really get hairy. To install, scalop requires 95 dependencies. Upon successful installation of all 95, the installation for scalop will eventually still fail, like so:

I am writing to ask if anyone knows enough about this output to know what to do to fix the "fatal error, 'S.h' file not found" error, which ultimately kills the download.
Several people have reached out to the author, as per the issues posted on scalop; specifically issues 4 and 5, but no reply. Additionally, posting the error message into google does not return useful hits, so far as I can see.
Finally, I am happy to provide any and all necessary info; e.g. sessionInfo(), R version (4.3) Mac OS (11.7) etc.
Help me Stack Overflow-Kenobi, you're my only hope.
| Fatal error relating to "include S.h" when installing R 'scalop' package | The "S.h" headers file is from the "S" language (the precursor to R); replacing "S.h" with "R.h" fixes the 'cant find S.h' error, but causes other issues. Clearly this package is not being maintained :(
I've forked the repository and made a couple of changes to the source code (commits fe15cf9 and ab9fe5c). I successfully installed both the scalop and infercna packages via Bioconductor, but there are a lot of warnings when they compile. I used gcc to compile them, rather than Apple Clang, with these flags:

This is how I installed the packages:

library(BiocManager)
BiocManager::install("Homo.sapiens")
BiocManager::install("jpmam1/scalop") # my forked copy
BiocManager::install("jlaffy/infercna")

76383296 | 76385696 | I have searched widely but not found an answer to this question:
Is it possible to change a variable in a Jetpack compose user interface from a broadcast receiver?
| Broadcast receiver change UI | You can't modify your compose ui from Broadcast receiver directly. Instead, your Broadcast receiver should change some data in your data layer - datastore, preferences, database or just in memory in some Repository singleton class. Then you should make this data observable and observe them from your compose ui.
|
76389017 | 76389067 | I have a template function
template <typename B, typename A>
B func(A x) {/*do something*/}
And in my code I am doing something like
uint32_t a[6] = {1,2,3,4,5,6};
uint64_t b = func(a);
But this fails with
test.cxx:10:16: error: no matching function for call to 'func'
uint64_t b = func(a);
^~~~~~~~~
test.cxx:5:6: note: candidate template ignored: couldn't infer template argument 'B'
So it seems that the type of a is automatically deduced but the type of b not. I can specify it (uint64_t b = <uint64_t>func(a);), sure, but why the compiler is not able to deduce it?
EDIT
Following comments also posting the content of the function (which is actually taking 2 other parameters)
template <typename B, typename A>
B bit_slice(A words[], int start, int end) {
int wordSize = sizeof(A)*8;
B s = 0;
int n = end / wordSize;
for(int i= 0; i <= n; ++i){
s = (s << wordSize) + words[i];
}
s >>= (n+1) * wordSize - (end+1);
B mask = (((T)1) << (end - start + 1))- 1;
s &= mask;
return s;
};
So basically a bit slicing of an array (representing something).
| Automatic template argument deduction fails for return type | If the argument cannot be deduced from func(a); then it cannot be deduced. auto return type can be deduced from the return statement, but not here. What you assign the return value to is not relevant. It simply doesnt work like this.
It does work however with a templated conversion:
#include <iostream>
#include <cstdio>
template <typename A,typename B>
A the_implementation(B x) { return x*2; }
template <typename B>
struct proxy {
B b;
template <typename A>
operator A() {
return the_implementation<A>(b);
}
};
template<typename B>
proxy<B> func(B x) {
return {x};
}
int main() {
int x = 42;
int y = func(x);
}
func returns a proxy<B>, B is deduced from x. Then proxy<B> can be converted to int via its conversion operator, which calls the actual function (because only now A and B have been deduced).
However, I have doubts that the above is a good idea in your code. Consider to write instead:
auto b = func<uint64_t>(a);

76381199 | 76387620 | I am on a learning curve with Kubernetes and recently started working with K3D. I am trying to deploy my project on a local K3D cluster. When I created a pod to run an application, I saw it hang in the pending state for some time, and below is the kubectl describe pod output (events).
application.yaml file's resource requirements are as below
resources:
requests:
memory: "4Gi"
cpu: "2"
The output of kubectl decribe node is as below: I assumed this was due to the fact that my node has around 3 GB of memory and the app is requesting 4 GB. I am getting the error in Pod. I looked for an answer to increase the memory but had no luck so far.
How can I increase the memory to get the application up and running? If I reduce the app.yaml resource to --> memory: 3 Gi or 2 Gi, the app starts running, but the actual functionality of the app is not there. Whenever I try to do something in the app, it then gives me Not enough CPU and/or memory is available for error in my application.
I am running this on Linux and k3d version k3d version v5.5.1 k3s version v1.26.4-k3s1 (default)
Thanks!
| How to increase allocated memory in a k3d cluster | Assuming the machine where you are running has more than 3GB of RAM (you can check by running lsmem or free), you can try re-creating the Kubernetes cluster using k3d, by passing an explicit memory limit. E.g.
k3d cluster create --agents-memory 8G
Or if you are doing a multi-node deployment, by adding a node with sufficient memory, e.g.
k3d node create --memory 8G
But when running on Linux, you typically would not have a memory limit applied to the Kubernetes cluster, unless that limit was requested explicitly. So I would suggest checking your previous cluster creation commands, or double-check any scripts you may have used.
If you are running Linux, another option is to run k3s directly, without k3d. That is unlikely to see limits applied to it as well.
Finally, an alternative is to use an ephemeral cloud environment for this type of testing. For example, using https://namespace.so you can create a Kubernetes cluster with 8GB of RAM in a few seconds, and use it to test your application.

76382660 | 76385756 | I'm writing a small interface in PyQT5 that has a graph that I use PyQtGraph to create. The graph starts to be drawn by pressing the "Start" button, and at first everything looks fine:
But over time and an increase in the number of points, the entire graph shrinks to the width of the screen and becomes not informative:
In this regard, there are two questions:
How can I make the window not try to fit the whole graph at once, squeezing it, but rather move behind it, showing the latest data?
Now the data comes in once a second and I redraw the graph every time. Is it possible to make it a partial update so that I just pass only new data into it?

step 2: in the draw_graph function use the getData() and setData() functions of the PlotcurveItems, update them

76388928 | 76389086 | The following is a minimum example code with the problem.
struct TestView: View {
@State var text = "Hello"
let useCase = TestUseCase()
init() {
useCase.output = self
}
var body: some View {
Text(text)
.onAppear {
// β useCase.output = self
useCase.show()
}
}
}
extension TestView: TestUseCaseOutput {
func showText(text: String) {
self.text = text
}
}
class TestUseCase {
var output: TestUseCaseOutput?
func show() {
output?.showText(text: "Changed")
}
}
protocol TestUseCaseOutput {
func showText(text: String)
}
This code changes the text from "Hello" to "Changed" when the view is displayed, but the change is not reflected. The showText method was called, but it had no effect. I also found that if I set the delegate at β , the text was updated correctly.
Can anyone tell me the cause of this problem?
| Can not update @State variable via delegate set in View.init() | SwiftUI views are structs, and therefore immutable. Whenever a SwiftUI changes, a new instance of that view struct is created.
When you update text, SwiftUI needs to create a new instance of TestView. But, the new instance has text set to Hello (and it was also have a new instance of TestUseCase) so you don't see any change.
The sequence of events is:
You create an instance of TestView - This is initialised with text = "Hello"
You update text which triggers SwiftUI to recreate TestView
The newly created instance of TestView is initialised with text = "Hello"`
In SwiftUI no object should ever need to hold a reference to a View.
init() {
useCase.output = self
}
The self you store in your TestUseCase instance will be thrown away as soon as the view is updated. It simply isn't useful to try and hold references to SwiftUI views.
You should structure your code so that views respond to changes in your model (Via @Published for example). Your model should never try and update a view directly.

76387588 | 76387690 | I'm using a library which requires a function with a void* pointer as a parameter. I have a 2D string array and I want to pass that array through that parameter and extract it inside the function. I successfully passed the array as a pointer but I don't know how to convert that pointer back to my array.
This is my current code:
String str_array[100][10];
int callback(void* data) {
String* str_array_ptr[100][10] = (String* [100][10])data;
(*str_array_ptr)[0][0] = "text";
return 0;
}
void test() {
callback(&str_array);
}
However, when compiling, I obtain the following error message:
error: ISO C++ forbids casting to an array type 'String* [100][10]' [-fpermissive]
PS: I'm trying to use the SQLite library's sqlite3_exec() function and store the result of a "SELECT SQL query" into a 2D string array.
SQLite C Interface - One-Step Query Execution Interface
| Casting a void pointer to a 2D String array pointer (C/CPP) | You cannot cast a pointer to an array. Instead you access your array through another pointer. That pointer has type String (*)[10]. Like this
String str_array[100][10];
int callback(void* data) {
String (*str_array_ptr)[10] = (String (*)[10])data;
str_array_ptr[0][0] = "text"; // Note no '*'
return 0;
}
void test() {
callback(str_array); // Note no '&'
}
Both the way you create the pointer, you don't need to use &, and the way you access the pointer, you don't need to use *, are also wrong in your code. See the code above for details.
The fundamental issue here (and maybe the issue you are misunderstanding) is the difference between String *x[10]; and String (*x)[10];. In the first case x is an array of 10 pointers to String, in the second case x is a pointer to an array of ten String. It's the second option that you want.

76382813 | 76385918 | Currently transitioning from BizTalk 2013r2 to 2020, and implementing Azure Pipelines to automate deployment with BTDF.
So far, we're able to deploy our Core applications, but we've just realised there are dependencies with the 'child applications' (applications that take schemas from the Core apps).
How should I refer to the Core application within Visual Studio in our dev environment (we used to reference the .dll from the local repos solution)
How can we configure BTDF and CI/CD pipelines to point to the correct application when deploying the child?
What happens if we need to update the Core application via BTDF/Pipeline - we'll need to undeploy all child applications that reference it before we can deploy surely - can this be done via the BTDF config?
| BizTalk 2020 with BTDF & Azure Pipelines - Application dependencies | No, I don't believe that BTDF can take care of that.
You should either.
Version increase your assembly version number of your Core Application and do a side by side deployment (e.g. leave the original ones in place).
Later on when you need the newer version in the dependent application then reference the later DLL (and yes, just have the DLL as an external assembly in the solution).
Or
Have your Core Application Pipeline undeploy all the dependent applications, before undeploying the Core Application and deploying it, and then re-deploying all the dependent applications.
My preference would be for the first option, less complicated.

76387658 | 76387707 | I have used a custom DisplayConverter on some columns of my Nattable.This displayconverter shows long values as hex strings.
Whenever I scroll my Nattable horizontally, this converter shifts one/mulitple columns. This results in columns which show hex values to be shown in default numeral format. On the other hand, columns which should be showing numerals show hex values.
In the following images, the first image shows how it should be displayed, that is column number 2 and 7 should show hex values (these are just long values with my custom converter applied).
When I scroll my table to the right, this converter is then applied to column number 3 and 8.
Default (as it should be)

| Nattable Display converter shifts columns when the table is scrolled horizontally | This happens if you apply your custom labels (HEX_FORMAT in your case) on the ViewportLayer or above.

76383599 | 76386234 | Subject 1: I am using Laravel version 7 in my project, and in order to add a query to all my models in Laravel, I have added a global scope to all my models. In this way, all my models inherit from another model. The mentioned model is provided below.

Subject 2: There is a model named "user" and a model named "role", and there is a many-to-many relationship between these 2 tables. Now, imagine that I want to retrieve all the roles associated with a user in the "user" model using the belongsToMany method, based on their relationship defined in the intermediate table.
/**
* The roles that belong to the user.
*/

| Getting SQLSTATE[23000] error with Laravel global scope in many-to-many relationship | I believe you got that error because a number of your tables are having that client_token column. So when you got a database query involving multiple tables, it just doesn't know which client_token column you are talking about.
Lets create a scope class so we can access the table name of the model:
<?php
namespace App\Scopes;
use Illuminate\Database\Eloquent\Scope;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Builder;
class ClientTokenScope implements Scope
{
/**
* Apply the scope to a given Eloquent query builder.
*
* @param \Illuminate\Database\Eloquent\Builder $builder
* @param \Illuminate\Database\Eloquent\Model $model
* @return void
*/
public function apply(Builder $builder, Model $model)
{
$builder->where("{$model->getTable()}.client_token", Client::$Current_Token);
}
}
Then applying the scope in the boot method:
namespace App\Models;
use App\Scopes\ClientTokenScope;
use Illuminate\Database\Eloquent\Builder;
class Model extends \Illuminate\Database\Eloquent\Model
{
/**
* The "booting" method of the model.

{
parent::boot();
if(!empty(Client::$Current_Token)) {
static::addGlobalScope(new ClientTokenScope);

| Return data from database and show in calendar | You are configuring your event incorrectly - when defining event_data, you define a single event that has arrays of all of the events. For example, the first event has the date of all of them. Since there is only one, you end up with day = ["23"] instead of 23, which is breaking the calendar code. You also need to convert each element to a number, as they are currently strings. Here is the correction:
var event_data = {
"events": []
};
for (var i = 0; i < verif.length; i++) {
event_data.events.push({
"occasion": verif[i],
"invited_count": Number(verif1[i]),
"year": Number(verif2[i]),
"month": Number(verif3[i]),
"day": Number(verif4[i]),
"cancelled": true
});
}
This code adds an event to event data for each item in verif.
In addition, earlier in your code, you define Dia incorrectly, with the month rather than the day.
Correction:
var Dia = datta[0].Dia;
rather than
var Dia = datta[0].Mes;

76381797 | 76387767 | I want to get the Calendar Events of all of the members in the organization/team via Power Automate. As I see now the "Get Calendars (V2)" and the "Get Calendar View of Events (V3)" only return the corresponding values of the user itself (the one who owns the flow). I was wondering if there's a way to get the calendar events of the group members given the fact that they've given the corresponding permission to share all the calendar data with the organization members.
Any help on this will be much appreciated.
Thanks!
| Get Calendar Events of all group members via Power Automate | The built-in connector will use the current user.
I don't think you can impersonate a user this way.
The best approach or alternative is to use Graph API with a servcie account (Azure AD app registration). You can get events from anyone, so from each users part of a group.
GET /users/{id | userPrincipalName}/calendar/events
GET /groups/{id}/members
To call Graph API with Power Automate you will need HTTP connector (it's a premium connector and the connector must be enable for your environment)
You have to declare a service account in Azure AD (or Microsoft Entra):
Create a new app registration (Applications > App registrations)
Copy the client id
Copy the tenant id
Add the following permissions (Applications > App registrations > API permissions)
Graph API > Application > Calendars.Read.All
Graph API > Application > Directory.Read.All
Graph API > Application > GroupMember.Read.All
Grant admin consent for the permissions
Generate a client secret (Applications > App registrations > Certificate & secrets > Client secrets)
In Power Automate, create a new cloud flow, for example a button with the group id as input.
Declare variables:
Client ID on the app registration
Client secret for the app registration
Tenant ID
Array to store all the events
Next, call Graph API to get group members with the generic HTTP connector
Method: GET
URI: https://graph.microsoft.com/v1.0/groups/<your group id input>/members

76387472 | 76387866 | My goal is to change value 99999 with the value adjacent to it unless it's 99999 again.
I took the advice from here before, now I am having a new problem.
MRE:
'as' is a dataframe with 9 different cohort datasets; 10030 obs of 7060 variables. I am mainly (as of now) dealing with as$AS1_WEIGHT ... as$AS9_WEIGHT

colnames()
[1] "AS1_WEIGHT" "AS2_WEIGHT" "AS3_WEIGHT" "AS4_WEIGHT" "AS5_WEIGHT" "AS6_WEIGHT" "AS7_WEIGHT" "AS8_WEIGHT"
[9] "AS9_WEIGHT"
Thank you in advance!
| tidyr::pivot_longer() with duplicate problems with no apparent duplicate column names or dataset in R | I suspect you already have a column named name or value before you run pivot_longer, which by default tries to create columns with those names. As noted here, the error message isn't necessarily clear that's the problem.
Try grep("name", colnames(as)) and grep("value", colnames(as)) to find those columns.
Either rename in your data frame or use pivot_longer( ... names_to = "a_new_name_col", values_to = "a_new_value_col")

76383552 | 76386291 | I have a has_many_through association where Users have many Projects through ProjectUsers. Rails has some magic that allows updating this relationship with:
u = User.first
u.update(project_ids: [...])
Is there a clean way to do the same thing with create?
Running User.create(name: ..., project_ids: [...]) fails with Validation failed: Project users is invalid.
I suspect this is because Rails tries to create the ProjectUser record before creating the User record and has some built-in validation on join tables to validate that both sides of the join already exist. The ProjectUser model has no custom validation.
class ProjectUser < ApplicationRecord
belongs_to :project
belongs_to :user
end
Is there a simple way to get around this?
| Create Record With "has_many_through" Association β Ruby on Rails | Active Record supports automatic identification for most associations with standard names. However, Active Record will not automatically identify bi-directional associations that contain the :through or :foreign_key options. (You can check here)
So you have to define inverse_of explicitly.
class Project < ApplicationRecord
has_many :project_users, foreign_key: :project_id, inverse_of: :project
has_many :users, through: :project_users
end
class User < ApplicationRecord
has_many :project_users, foreign_key: :user_id, inverse_of: :user
has_many :projects, through: :project_users
end

76387583 | 76387869 | Can anyone explain why the SQL function (using SQL Server 2019) returns results that to me appear to be counter intuitive? Here are the queries and the scores:

I understand DIFFERENCE uses SOUNDEX to match consonants phonetically, but the results above seem very odd particularly with the second query. Is it something to do with the space and the proceeding string?
| SQL Function DIFFERENCE returns interesting scores | If you change the order of words you will see there is a bias on the first word. Then if you consider SOUNDEX you will begin to understand why. Also read the reference below.
SOUNDEX converts an alphanumeric string to a four-character code that is based on how the string sounds when spoken in English. The
first character of the code is the first character of
character_expression, converted to upper case. The second through
fourth characters of the code are numbers that represent the letters
in the expression. The letters A, E, I, O, U, H, W, and Y are ignored
unless they are the first letter of the string. Zeroes are added at
the end if necessary to produce a four-character code. For more

I would like to get, for every distances_ column, the index with the minimum value.

How could I do that ?

76381633 | 76387897 | I have a pandas dataframe which is sorted by a date column. However I wish to ensure a minimum time interval between observations. Say for simplicity this window is 10 minutes, what this means is that if my first observation occurred at 8:05 AM then the second observation must occur at at least 8:15 AM. Any observations occurring between 8:05-8:15 AM must be dropped from the dataframe. Say without loss of generality that after dropping observations the second observation occurs at 8:17 AM. Then all observations between 8:17-8:27 AM are dropped to find the third data point and this process continues.
I have a script which works but iterates over the rows one at a time and is excruciatingly slow as the dataframe has hundreds of thousands of rows. My current script (window is the minimum threshold in minutes):
cur_time = df.iloc[0].Date
for idx, row in df[1:].iterrows():
time_diff = (row.Date - cur_time).total_seconds()
if time_diff > window*60:
cur_time = row.Date
else:
trades_df.drop(idx, inplace=True)
Can anyone think of a more speed optimized way of doing this operation? If I switch to the Date column as the index are there functions readily available for performing this function?
Edit: After doing further research the function that I'm looking for is similar to df.resample(window + 'M').first(). However the issue with using this is that my data set is sparsely spaced. I.e. I don't have data for every minute, the gap between data points could be 1 second or it could be 1 month.
| Ensuring a minimum time interval between successive observations in a Pandas dataframe | With your condition mentioned in comments, I think you can't vectorize whole code. However, you can browse through the dataset faster:
window = 10
# convert date as numpy array (in seconds)
arr = df['Date'].values.astype(float) / 1e9
# compute dense matrix using numpy broadcasting
m = arr - arr[:, None] > window * 60
locs = [] # list of valid observations
idx = 0 # first date is always valid
while True:
# append the current observation
locs.append(idx)
if m[idx].sum() == 0:
# no more observations to check
break
# next valid observation
idx = np.argmax(m[idx])
out = df.iloc[locs]

I can understand that it roughly contains some major parts in order to implement a type trait such as isDefaultConstructible or hasFirst trait (isvalid1.cpp):
1. Helper functions using SFINAE technique:
#include <type_traits>
// helper: checking validity of f(args...) for F f and Args... args:
template<typename F, typename... Args,
typename = decltype(std::declval<F>()(std::declval<Args&&>()...))>
std::true_type isValidImpl(void*);
// fallback if helper SFINAE'd out:
template<typename F, typename... Args>
std::false_type isValidImpl(...);
2. Generic lambda to determine the validity:
// define a lambda that takes a lambda f and returns whether calling f with args is valid
inline constexpr
auto isValid = [](auto f) {
return [](auto&&... args) {
return decltype(isValidImpl<decltype(f),
decltype(args)&&...
>(nullptr)){};
};
};
3. Type helper template:
// helper template to represent a type as a value
template<typename T>
struct TypeT {
using Type = T;
};
// helper to wrap a type as a value
template<typename T>
constexpr auto type = TypeT<T>{};
// helper to unwrap a wrapped type in unevaluated contexts
template<typename T>
T valueT(TypeT<T>); // no definition needed
4. Finally, compose them into isDefaultConstructible trait to check whether a type is default constructible:
constexpr auto isDefaultConstructible
= isValid([](auto x) -> decltype((void)decltype(valueT(x))()) {
});
It is used like this (Live Demo):
struct S {
S() = delete;
};
int main() {
std::cout << std::boolalpha;
std::cout << "int: " << isDefaultConstructible(type<int>) << std::endl; // true
std::cout << "int&: " << isDefaultConstructible(type<int&>) << std::endl; // false
std::cout << "S: " << isDefaultConstructible(type<S>) << std::endl; // false
return 0;
}
However, some of the syntax are so complicated and I cannot figure out.
My questions are:
With respect to 1, as for std::declval<F>()(std::declval<Args&&>()...), does it mean that it is an F type functor taking Args type constructor? And why it uses forwarding reference Args&& instead of simply Args?
With respect to 2, as for decltype(isValidImpl<decltype(f), decltype(args)&&...>(nullptr)){} , I also cannot understand why it passes forwarding reference decltype(args)&& instead of simply decltype(args)?
With respect to 4, as for decltype((void)decltype(valueT(x))()), what is the purpose of (void) casting here? ((void) casting can also be found in isvalid1.cpp for hasFirst trait) All I can find about void casting is Casting to void to avoid use of overloaded user-defined Comma operator, but it seems it is not the case here.
Thanks for any insights.
P.S. For one who wants more detail could check C++ Templates: The Complete Guide, 2nd - 19.4.3 Using Generic Lambdas for SFINAE. The author also mentioned that some of the techniques are used widely in Boost.Hana, so I also listen to Louis Dionne's talk about it. Yet, it only helps me a little to understand the code snippet above. (It is still a great talk about the evolution of C++ metaprogramming)
| Have difficulty understanding the syntax of generic lambdas for SFINAE-based traits |
F is a function object callable with Args...
For the sake of mental model, picture std::declval<F>() as a "fully constructed object of type F". std::declval is there just in case F is not default-constructible and still needs to be used in unevaluated contexts.
For a default-constructible type this would be equivalent:
F()(std::declval<Args&&>()...); In essence it's a call to F's constructor and then call to its operator() with forwarded Args. But imagine one type is constructible with int, another one is default-constructible, yet another one requires a string. Without some unevaluated constructor-like metafunction it would be impossible to cover all those cases.
You can read more on that in Alexandrescu's Modern C++ Design: Generic Programming and Design Patterns Applied.
Adding && to the argument type is effectively perfect-forwarding it. It may look obscure, but it's just a shorthand for decltype(std::forward<decltype(args)>(args)). See the implementation of std::forward and reference collapsing rules for more details. Keep in mind though, that this snippet adds rvalue-reference that collapses to the correct one when combined with the original type, not a forwarding one.
As it was stated in the comments: the type is not really needed, possibilty exists it cannot be returned, its presence there is just to check expression's correctness, afterwards it can be discarded.

Remove the inline onclick and onload attributes. They are outdated and not good practice. Use addEventListener() to bind events within JS, instead of HTML.
Set points to be a numeric value, not a string. This way there's no type coercion needed when you increment its value.

76382922 | 76386636 | I have very CPU heavy process and would like to use as many workers are possible in Dask.
When I read the csv file using the read_csv from dask and then process the dataframe using map_partitions only one worker is used. If I use read_csv from pandas and then convert the file to a Dask dataframe, all my workers are used. See code below.
Could someone explain the difference in behavior?
Ideally, I would like to use read_csv from Dask so that I dont have to have a conversion step. Could anyone help me with that?
import dask as d
import pandas as pd
def fWrapper(x):
p = doSomething(x.ADDRESS, param)
return(pd.DataFrame(p, columns=["ADDRESS", "DATA","TOKEN", "CLASS"]))
# only use 1 worker instead of the available 8
dask_df = d.dataframe('path\to\file')
dask_df.set_index(UID, npartitions = 8, drop = False)
ddf2 = dask_df.map_partitions(fWrapper, meta={"ADDRESS" : object, "DATA" : object, "TOKEN" : object, "CLASS" : object}).compute()
#uses all 8 workers
df = pd.read_csv('path\to\file')
df.set_index('UID', drop=False)
dask_df2 =d.dataframe.from_pandas(df, npartitions=dask_params['df_npartitions'], sort=True)
ddf3 = dask_df2.map_partitions(fWrapper, meta={"ADDRESS" : object, "DATA" : object, "TOKEN" : object, "CLASS" : object}).compute()
| Dask map_partition does no use all workers on client | The DataFrame.set_index method in both dask.dataframe and pandas returns the updated dataframe, so it must be assigned to a label. pandas does have a convenience kwarg inplace, but that's not available in dask. This means that in your snippet, the first approach should look like this:
dask_df = dask_df.set_index(UID, npartitions = 8, drop = False)
This will make sure that the new indexed dask dataframe has 8 partitions, so downstream work should be allocated across multiple workers.

76378627 | 76387024 | I made a program where users can keep track of their expenses by entering them into the system after creating their own account. The system requires users to fill in four fields: customer, category, price, and month. I would like the first field (customer) to automatically populate with the username of the logged-in user, so that users don't have to choose from all available customers.
However, I encountered an issue where users are unable to create objects in the system. I can only create objects through the admin dashboard. When I try to create an object on the page, it throws an error message saying,
RelatedObjectDoesNotExist at / User has no customer.
I suspect this problem is related to the fact that users are added in the authentication and authorization section under Users in the admin page, instead of being created under Customers by my app, alongside the Finance section where the objects are stored.
To summarize my two main issues:
I want the first field to automatically populate with the username of the logged-in user.

76383379 | 76387122 | I am learning x86-64 assembly with an online course and the course is horribly unclear in detail. I've searched online and read several SO questions but couldn't get an answer.
I tried to figure out how to calculate binary multiplication by hand, but I am stuck with imul .
Given this example of binary multiplication, 11111111 * 00000011, it can be viewed as 255 * 3 unsigned or -1 * 3 signed.
255*3
mov al, 255
mov bl, 3
mul bl
this is easy and here's how I calculate by hand, just like decimal multiplication:
11111111
x 00000011
--------------
11111111
11111111
--------------
1011111101
The result overflows, the upper half is 10 in ah and the lower half is 11111101 in al. My manual calculation matches the program result.
-1*3
when it comes to signed,
mov al, -1
mov bl, 3
imul bl
the program result is 11111111 in ah and 11111101 in al.
How can I calculate this result by hand? I was told that sign extension is involved in imul, but I really don't know how it works here.
I am using SASM IDE and NASM Assembler.
| How do you manually calculate imul -1 * 3? | Honestly, I can't fully understand the other two answers. It's over complicated for me. I just need a dumb, simple and universal rule.
I'd like to just pick up what works for me.
The result is equivalent to sign-extending (imul) or zero-extending
(mul) both inputs to the destination width and then doing a
non-widening multiply
@Peter Cordes
To manually compute there are several approaches: you can sign extend
both inputs to 16-bits and do 16 Γ 16 keeping only the low 16-bits
@Erik Eidt
I tried and verified and this rule works for me.
-1*3,
sign extended
11111111 11111111
x00000000 00000011
-------------------
11111111 11111111
111111111 1111111
-------------------
1011111111 11111101
keep the low 16 bits, I get the correct result 11111111(ah) 11111101(al).
Try a 4 bit example:
-2 * 3, 1110 imul 0011
sign extended
1111 1110
x0000 0011
-----------
1111 1110
11111 110
-----------
101111 1010
keep the lower 8 bits, the result is 1111 1010, -6.
Before I wasn't sure how sign extended works in imul, now I get it and it's easy to verify. Btw, if you find manual calculation tedious for some examples (e.g. 4 bit -7 * -1, 1001 x 1111, sign extended 1111 1001 x 1111 1111, many lines to add), you can use the Windows Calculator (programmer mode) and verify the result very quickly.

76387859 | 76387955 | I faced an issue when I had to terraform import some role_assignment resources, specially regarding the APP CONFIG DATA READER role assignment, in terraform.
the problem I had to solve was due to an evolution of our iac to make the terraform plan more readable and explicit.
Here is the code for role assignment that changed :
module "my_role_assignment_slot_to_app_config" {
for_each = local.map_slot_app_config
source = "../../resourceModules/role_assignment"
scope = each.value.config_id
role_definition_names = ["Reader","App Configuration Data Reader"]

}
with the following module for role assignments :
```hcl
resource "azurerm_role_assignment" "my_role_assignment" {
for_each = toset(var.role_definition_names)
scope = var.scope
role_definition_name = each.value
principal_id = var.principal_id
}
This code would plan the following, more readable :
But as you can see, the index for the azurerm_role_assignment.my_role_assignment contains spaces.
This was preventing us to terraform import the role assignment (as it has been created manually before the iac was coded) using powershell script in an azureCli task on azure Devops :
- task: AzureCli@2
displayName: Runs tfImport.ps1
condition: and(succeeded(), eq(variables['toUpdate.scriptExists'], 'true')) # test script presence
name: tfImport.ps1
inputs:
azureSubscription: ${{ parameters.serviceConnection }}
scriptType: ps
scriptLocation: InlineScript
inlineScript: |
$Env:ARM_CLIENT_ID = "$Env:servicePrincipalId"
$Env:ARM_CLIENT_SECRET = "$Env:servicePrincipalKey"
$Env:ARM_TENANT_ID = "$Env:tenantId"
$Env:ARM_SUBSCRIPTION_ID = az account list --query "[?isDefault].id" -o tsv
$Env:TF_LOG = "${{ parameters.TF_LOG }}"
terraform init `
-migrate-state `
-backend-config="resource_group_name=${{ parameters.storageAccountResourceGroup }}"`
-backend-config="storage_account_name=${{ parameters.storageAccount}}" `
-backend-config="key=${{ parameters.storageContainer }}" `
-backend-config="container_name=${{ parameters.stateBlobContainer }}"
// runs my tfImport.ps1 script here
./tfImport.ps1
workingDirectory: $(pipeline_artefact_folder_extract)/
addSpnToEnvironment: true
failOnStderr: false
continueOnError: true
The script I used had the following terraform import line,
terraform import 'module.my_role_assignment_slot_to_app_config[\"sit03_z-adf-ftnd-shrd-npd-ew1-cfg01\"].azurerm_role_assignment.my_role_assignment[\"App Configuration Data Reader\"]' /subscriptions/**********/resourceGroups/*********/providers/Microsoft.AppConfiguration/configurationStores/z-adf-ftnd-shrd-npd-ew1-cfg01/providers/Microsoft.Authorization/roleAssignments/<role_assignment_id>
and so I've had the following error :
(id datas removed)
After some researches, I've found the following link that explains the why and give to me one start of solution :
https://github.com/hashicorp/terraform/issues/25116
But I had to go further and find a way to use my powershell script without the startProcess method.
And as I had also to get my role_assignment resourceId from its PrincipalId (as we can gets the PrincipalId of resources that have the 'App Configuration Data Reader' role on the app_config using the following)
# role assignment over a specific scope (such as app_config)
$rsRolesCfg = az role assignment list --scope /subscriptions/******/resourceGroups/*******/providers/Microsoft.AppConfiguration/configurationStores/******-cfg01 | ConvertFrom-Json
$myRole = $rsRolesCfg | Where-Object roleDefinitionName -eq 'App Configuration Data Reader' | Where-Object id -like "*<app_config_resourceId>"
## principalId is the id of the object that get the role over the scope !
# GetsresourceId from PrincipalId / ObjetcId (without the '<>' on body, off course :) ) :
$resourceId = (az rest --method POST --url 'https://graph.microsoft.com/v1.0/directoryObjects/getByIds' --headers 'Content-Type=application/json' --body '{\"ids\":[\"<PrincipalId>\"]}' | ConvertFrom-Json | Select-Object value).value.alternativeNames[1]
Solution from How to Get Azure AD Object by Object ID Using Azure CLI (thanks a lot !)
I had to test it locally in powershell terminal... So it did not work as expected.
So then, I change a little bit the script and got the solution (next post, as solution from my problem).
| Maps containing keys with spaces are not properly validated when those keys are used as resource names | So I've had to test my get_ResourceId methods in local on a powershell VSCode terminal, that does not accept the above code (as the paces wher badly interpreted by powershell)
So, after a quick search that explain to me that the "`" was the escape character for Powershell, I've tested this that works and give to me the expected resourceId for role_assignment :
$rsRolesCfg = az role assignment list --scope /subscriptions/************/resourceGroups/******/providers/Microsoft.AppConfiguration/configurationStores/<app_configuration_name> | ConvertFrom-Json
($rsRolesCfg | Where-Object roleDefinitionName -eq 'App Configuration Data Reader') | ForEach-Object {$local=$_.principalId; (az rest --method POST --url 'https://graph.microsoft.com/v1.0/directoryObjects/getByIds' --headers 'Content-Type=application/json' --body "{\`"ids\`":[\`"$local\`"]}" | ConvertFrom-Json | Select-Object value).value.alternativeNames[1] }
So, the use of "`" was the solution for my point, so I've tried to use it on my terraform import script (on first post) and it works fine also :
terraform import "module.my_role_assignment_slot_to_app_config[\`"sit03_z-adf-ftnd-shrd-npd-ew1-cfg01\`"].azurerm_role_assignment.my_role_assignment[\`"App Configuration Data Reader\`"]" /subscriptions/*****/resourceGroups/******/providers/Microsoft.AppConfiguration/configurationStores/z-adf-ftnd-shrd-npd-ew1-cfg01/providers/Microsoft.Authorization/roleAssignments/<role_assignment_id>
But I had also to change the yaml task, using pscore rather than ps, like the following :
- task: AzureCli@2
displayName: Runs tfImport.ps1
condition: and(succeeded(), eq(variables['toUpdate.scriptExists'], 'true')) # test script presence
name: tfImport.ps1
inputs:
azureSubscription: ${{ parameters.serviceConnection }}
scriptType: **pscore**
So then, the terrform import script was running with success !
I've used the same "title" for this stackOverflow question / solution as the one in the GitHub, so them peoples who are lokking for that solution could find easily the solution with the question... At least, I hope so :-P
thanks for reading !

76378706 | 76387141 | In C++, I can't find a way to appropriately terminate a WMI session with a remote server. Any attempt to release the IWbemServices pointer throws an exception; the TCP connection to the server remains established until the process exits (it's open after the last CoUninitialize call). This problem (thrown exception) does not occur when connecting to the local machine.
I've looked at a similar question asked here, but the solution from Microsoft (retrieving the IUnknown pointer and releasing it first) didn't solve the issue.
Here's the code (error checking has been omitted for readability):
HRESULT hRes = S_OK;
IWbemLocator* pWbemLocator = NULL;
IWbemServices* pWbemServices = NULL;
// these three pointers are already initialized...
PWCHAR wcUser; // L"theuser"
PWCHAR wcPass; // L"thepassword"
PWCHAR wcAuth; // L"ntlmdomain:THEDOMAIN"
std::wstring wstrNsPath = L"\\\\remoteserver\\ROOT\\CIMV2";
hRes = CoInitializeEx(NULL, COINIT_MULTITHREADED);
hRes = CoCreateInstance(CLSID_WbemLocator, NULL, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID*)&pWbemLocator);
// this returns S_OK :)
hRes = pWbemLocator->ConnectServer((BSTR)wstrNsPath.c_str(),
(BSTR)wcUser,
(BSTR)wcPass,
NULL,
WBEM_FLAG_CONNECT_USE_MAX_WAIT,
(BSTR)wcAuth,
NULL,
&pWbemServices);
hRes = CoSetProxyBlanket(pWbemServices,
RPC_C_AUTHN_DEFAULT,
RPC_C_AUTHZ_DEFAULT,
COLE_DEFAULT_PRINCIPAL,
RPC_C_IMP_LEVEL_IMPERSONATE,
RPC_C_AUTHN_LEVEL_DEFAULT,
NULL, // domain info already specified in 'wcAuth'
EOAC_NONE);
// do some queries..
// cleanup
pWbemServices->Release(); // on remote sessions, this throws an exception
pWbemLocator->Release();
CoUninitialize();
The exception is displayed in the debug output (Visual Studio):
onecore\com\combase\dcomrem\call.cxx(1234)\combase.dll!0000ABCDEFABCDEF: (caller: 0000FEDCBAFEDCBA) ReturnHr(1) tid(4321) 80070005 Access is denied.
Is this expected behavior? Should the connection between the client and server not be terminated once the session is released?
I attempted to follow MSDN's advice and added the following after the CoSetProxyBlanket() call in the code above. It didn't change anything.
IUnknown* pUnknown = NULL;
pWbemServices->QueryInterface(IID_IUnknown, (LPVOID*)&pUnknown);
if (pUnknown)
{
hRes = CoSetProxyBlanket(pUnknown,
RPC_C_AUTHN_DEFAULT,
RPC_C_AUTHZ_DEFAULT,
COLE_DEFAULT_PRINCIPAL,
RPC_C_IMP_LEVEL_IMPERSONATE,
RPC_C_AUTHN_LEVEL_DEFAULT,
NULL,
EOAC_NONE);
pUnknown->Release();
}
Any advice is greatly appreciated!
EDIT So after capturing session packets, it would appear that setting the proxy security with pAuthInfo == NULL causes the request to be made by the current logged on user of the client machine. It ignores the credentials that I provided when calling ConnectServer. I'm aware that the COAUTHIDENTITY structure allows you to pass the correct credentials to CoSetProxyBlanket, but I'd like to avoid having to input the domain as a separate variable. In other words, is there a way that this information can be extracted using the wcAuth when the request is made to a remote server? If so, how could I distinguish local vs. remote requests?
Here is the output from Wireshark that led me to believe this is the problem (see packet 1617):

| (WMI) IWbemServices::Release() throws "Access Denied" exception when connected to remote machine | I was able to resolve the issue. If you are not using the current logged-on user token, you must specify the pAuthInfo parameter of CoSetProxyBlanket to a valid COAUTHIDENITY structure pointer. The docs for IWbemLocator::ConnectServer actually state that it's best practice to include the domain in the strUser parameter... and that if you do so, you must pass the authority string as NULL.
One thing to note is that if ConnectServer succeeds, you don't have to go crazy with the sanitizing of the username string for correctness; the login either worked or it didn't (and breaks/throws an exception, depending on how you handle errors). In other words, just search the string for the domain delimiters ('\\' or '@') and split them appropriately into domain name and username.

76383760 | 76387258 | I've been going through react-router's tutorial, and I've been following it to the letter as far as I'm aware. I'm having some issues with the url params in loaders segment.
The static contact code looks like this
export default function Contact() {
const contact = {
first: "Your",
last: "Name",
avatar: "https://placekitten.com/g/200/200",
twitter: "your_handle",
notes: "Some notes",
favorite: true,
}
And when it loads, it looks like this. That works just fine, however, the tutorial then tells me to change that code so that I use data that's loaded in instead. The code now looks like this
import { Form, useLoaderData } from "react-router-dom";
import { getContact } from "../contacts"
export async function loader({ params }) {
const contact = await getContact(params.contactid);
return {contact}
}
export default function Contact() {
const { contact } = useLoaderData();
According to the tutorial, it should just load in an empty contact that looks like this but instead, every time I try to open one of the new contacts, it kicks up an error saying
React Router caught the following error during render TypeError: contact is null
The actual line of code this error points to is in the return segment of the contact component, which looks like this
return (
<div id="contact">
<div>
<img
key={contact.avatar}
src={contact.avatar || null}
/>
</div>
<div>
<h1>
{contact.first || contact.last ? (
<>
{contact.first} {contact.last}
</>
) : (
<i>No Name</i>
)}{" "}
<Favorite contact={contact} />
</h1>
{contact.twitter && (
<p>
<a
target="_blank"
href={`https://twitter.com/${contact.twitter}`}
>
{contact.twitter}
</a>
</p>
)}
{contact.notes && <p>{contact.notes}</p>}
<div>
<Form action="edit">
<button type="submit">Edit</button>
</Form>
<Form
method="post"
action="destroy"
onSubmit={(event) => {
if (
!confirm(
"Please confirm you want to delete this record."
)
) {
event.preventDefault();
}
}}
>
<button type="submit">Delete</button>
</Form>
</div>
</div>
</div>
);
}
Pretty much anywhere contacts is called gets an error. So, anyone have any idea what I'm doing wrong here? To my knowledge, I've been following their guide to the letter and it seems like it should be able to handle contacts not having any data, but it's not.
These are the pieces of my code that are supposed to be working together to render a contact, or at least the pertinent parts
The router, this is the main file, the only part missing is the part where it's rendered
import * as React from "react";
import * as ReactDOM from "react-dom/client";
import {
createBrowserRouter,
RouterProvider,
} from "react-router-dom";
import "./index.css";
import Root, { loader as rootLoader, action as rootAction } from "./routes/root";
import ErrorPage from "./error-page";
import Contact, { loader as contactLoader } from "./routes/contact"
const router = createBrowserRouter([
{
path: "/",
element: <Root />,
errorElement: <ErrorPage />,
loader: rootLoader,
action: rootAction,
children: [
{
path: "contacts/:contactID",
element: <Contact />,
loader: contactLoader
}
]
}
These are the functions in the root file that are called when a new contact is made and when it needs to be displayed
import { Outlet, Link, useLoaderData, Form } from "react-router-dom"
import { getContacts, createContact } from "../contacts"
export async function action() {
const contact = await createContact();
console.log("Contact made")
return {contact}
}
export async function loader(){
const contacts = await getContacts();
return {contacts};
}
This is the createContacts function that gets called when a contact is created, and this is the getContacts function
export async function createContact() {
await fakeNetwork();
let id = Math.random().toString(36).substring(2, 9);
let contact = { id, createdAt: Date.now() };
let contacts = await getContacts();
contacts.unshift(contact);
await set(contacts);
return contact;
}
export async function getContact(id) {
await fakeNetwork(`contact:${id}`);
let contacts = await localforage.getItem("contacts");
let contact = contacts.find(contact => contact.id === id);
return contact ?? null;
}
This is the contacts.jsx file where things are currently going wrong. When a new contact is made, it's going to be empty, which I imagine is the source of the problem, but there are checks here to deal with that, or at least there are supposed to be.
import { Form, useLoaderData } from "react-router-dom";
import { getContact } from "../contacts"
export async function loader({ params }) {
const contact = await getContact(params.contactid);
return { contact }
}
export default function Contact() {
const { contact } = useLoaderData();
return (
<div id="contact">
<div>
<img
// these next two lines are where the errors typically start,
// although it seems to extend down to any instance where contact
// gets called.
key={contact.avatar}
src={contact.avatar || null}
/>
</div>
<div>
<h1>
{contact.first || contact.last ? (
<>
{contact.first} {contact.last}
</>
) : (
<i>No Name</i>
)}{" "}
<Favorite contact={contact} />
</h1>
{contact.twitter && (
<p>
<a
target="_blank"
href={`https://twitter.com/${contact.twitter}`}
>
{contact.twitter}
</a>
</p>
)}
{contact.notes && <p>{contact.notes}</p>}
<div>
<Form action="edit">
<button type="submit">Edit</button>
</Form>
<Form
method="post"
action="destroy"
onSubmit={(event) => {
if (
!confirm(
"Please confirm you want to delete this record."
)
) {
event.preventDefault();
}
}}
>
<button type="submit">Delete</button>
</Form>
</div>
</div>
</div>
);
}
| Going through the react-router tutorial and rather than using default or null values when loading an empty object, it kicks up an error | There are some subtle, but detrimental, casing issues in the route path params.
The Contacts component's route path param is declared as contactID.
const router = createBrowserRouter([
{
path: "/",
element: <Root />,
errorElement: <ErrorPage />,
loader: rootLoader,
action: rootAction,
children: [
{
path: "contacts/:contactID", // <-- "contactID"
element: <Contact />,
loader: contactLoader,
},
],
},
]);
The contact loader is referencing a contactid path parameter.
export async function loader({ params }) {
const contact = await getContact(params.contactid); // <-- "contactid"
return { contact };
}
As such, the loader function is unable to find a match and returns null to the Contact component. An error is thrown in the UI when attempting to access properties of the null reference.
Any valid Javascript identifier will work as the name of the route path parameter, but they should all be in agreement. Casing matters in variable names in Javascript. The common convention in variable names is to use camelCasing, e.g. contactId.
const router = createBrowserRouter([
{
path: "/",
element: <Root />,
errorElement: <ErrorPage />,
loader: rootLoader,
action: rootAction,
children: [
{
path: "contacts/:contactId",
element: <Contact />,
loader: contactLoader,
},
],
},
]);
export async function loader({ params }) {
const contact = await getContact(params.contactId);
return { contact };

76387927 | 76387999 | I would like to display either one of two images in a modal based on an API response...unfortunately, the API returns a long string array. I need to be able to determine if the word "Congratulations" is in this array. So far, I've tried a couple basic things:

{
id: 12,
message: ["1 bonus point!", "Congratulations", "You have leveled up!"]
}
console.log(response) // the full response prints to the console, no problem
console.log(response?.message) //undefined

I have two main tasks.
1-Generate token at interval of 10 mins

| PostgreSQL - Get value from from the same table | First of all, you need to fix your flaws in your table schema design, and declare:
dates with the "DATE" type (instead of VARCHAR(50))
week values with the INT type (instead of VARCHAR(5))
traffic values with the DECIMAL type (instead of FLOAT)
CREATE TABLE tab(
DATE DATE,
Tname VARCHAR(50),
Week INT,
Traffic DECIMAL(4,2)
);
Once you've carried it out, you can solve this problem by:
creating a ranking value for each day of the week in your weeks, using EXTRACT on your date
extracting your traffic value from previous week with LAG, by partitioning on your ranking created at previous step, and ordering on the week_number.
WITH cte AS (
SELECT date, Tname, Week, Traffic,
ROUND(AVG(Traffic) OVER(PARTITION BY Week), 2) AS AVGTraffic,
EXTRACT(ISODOW FROM date) - 1 AS week_day
FROM tab
)
SELECT date, Tname, Week,
LAG(Traffic) OVER(PARTITION BY week_day ORDER BY Week) AS prevweek_traffic,
AVGTraffic
FROM cte
ORDER BY Week, week_day
And if you realize that you may have holes among your weeks (..., week 17, week 18, week 20, week 21, ...) and specifically want values from the exact previous week (that may be missing), you can add a filter on the LAG function, that checks if week and previous week are consecutive:
...
CASE WHEN LAG(Week) OVER(PARTITION BY week_day ORDER BY Week) = Week-1
THEN LAG(Traffic) OVER(PARTITION BY week_day ORDER BY Week)
END
...
(in place of LAG(Traffic) OVER(...) only)
Output:

No, unless you save the MD5 as a field inside the database. If you do that, you'll be able to query using the MD5. Your schema should look like this:
db

|
--- email: "[email protected]"

There are two databases DB1 and DB2. In each of them there are tables "users" and "cities" with the names of cities. Users and city names are the same in both databases. But the city ID values are different in the two databases. In the first DB1 database, the "users" table contains the city IDs from the "cities" table.
I need to update the city data in the second DB2 database. For each "users" value from DB1, find the name "cities" and update the values in DB2.users. The problem is that the city ID values are different in the two databases. Only the names are the same.
| Update + join from two databases | Use an update with join:

76382701 | 76388249 | I've been using the Bitmap-class and it's png-ByteStream to deal with images in my WPF-application, mostly with reading/writing files, getting images from native cam libs and showing them in the UI.
Lately I've got some new requirements and tried to upgrade some of that to deal with 64 bit deep images (or 48 bits, I don't need an alpha channel). In pretty much every operation bitmap is converting my image back to 32bppArgb. I've figured out deepcopying and am currently looking into Image.FromStream(), but needing to deal with this got me wondering:
Is there a way to properly deal with non 32bppArgb-images within a C#-application (including true greyscale)? Or does microsoft just neglect the need for it? I've found some related questions, but mostly with 10 year old hacks, so I'd expect there to be a proper way by now...
Edit: As requested, I'm gonna show some code. It's running on .netStandard2.0 to be used mostly inside .net6.0 apps; with System.Drawing.Common on Version 5.0.2 (I don't think it matters but would be willing to upgrade if that's the case). Imagine nativeImage to be a struct from some cameraLib, so we want a deepcopy to get away from the shared memory:
using Bitmap bitmap = new(nativeImage.Width, nativeImage.Height, nativeImage.stride, PixelFormat.Format64bppArgb, nativeImage.DataPtr);
using Bitmap copy = bitmap.DeepCopy(); //custom function
using MemoryStream stream = new();
copy.Save(stream, ImageFormat.Png);
byte[] byteStream = stream.ToArray(); //Saving this to file shows it's really 64 bit
//These bits are stitched together for testing, normally this byte-Array might get passed around quite a bit
using MemoryStream ms = new(byteStream);
using Image image = Image.FromStream(ms, true); //this suddenly is 32bppArgb
with:
public static Bitmap DeepCopy(this Image original)
{
// this just copies the code of the Bitmap(Image)-constructor but uses the original pixelFromat instead of 32bppArgb
var result = new Bitmap(original.Width, original.Height, original.PixelFormat);
using (Graphics g = Graphics.FromImage(result))
{
g.Clear(Color.Transparent);
g.DrawImage(original, 0, 0, original.Width, original.Height);
}
return result;
}
| How to deal with 48 or 64bit images in C# | I do not think you will have much success with System.Drawing.Bitmap. In my experience these just have poor support high bit depths. I would instead take a look at the corresponding System.Windows.Media classes. I know PngBitmapEncoder/decoder at least support 16 bit grayscale, but I suspect 48/64 bit works fine as well.
For display I would expect that you would want to do your own tone mapping, since I have never seen any builtin method do a particular good job.
If you want a format for interchange I would suggest creating your own. Any image is essentially represented using just a few properties:
Width
Height
Stride - The number of bytes on a row. This must be at least large enough to fit a row of pixels, but may be larger for alignment reasons.
PixelFormat
Pixel Data - This can essentially anything representing binary data. Byte[], a pointer, a stream, Memory<T> etc. The total size of the data should be Height * Stride.
Most image processing libraries should have methods accepting raw image data. You might need to jump thru some hoops to get it to work, like using unsafe code or doing a blockCopy. You also likely need some mapping code to convert between all the various PixelFormat enums.
Libraries typically provide Bitmap access for convenience, but convert this data to some internal format as soon as possible. You should be able to do the same.

76387881 | 76388086 | The Ansible documentation has a list of Variable precedence
Some of them are clear to me but I wonder whether anybody coulde kinkdy shed some light on those 2.
20. role (and include_role) params
21. include params
usage, location, syntax.
I am trying to get Variable declaration a little further to the surface inside a little more complex playbook utilizing 2 roles I am currently working on.
concrete ... some values inside task files of a role should rather be declared as variables in a single location.
| Ansible Variable precedence - what are 'role params' & 'include params' | In a nutshell examples:
role params
(full playbook)
- name: I'm a dummy play
hosts: localhost
roles:
- role: somerole
vars:
param1: "I'm a role param"
Include role params
(task only)
- name: Including role somerole
ansible.builtin.include_role:
name: somerole
vars:
param1: "I'm an include role param"
Include params
(task only)
- name: Including a task file
ansible.builtin.include_tasks: sometasks.yaml
vars:
param1: "I'm an include param"
As a fictive and (most probably bad practice) example: if you include a role passing a parameter and later include a task file in that role passing that same parameter with a different value, the include param will take precedence over the role param.

76389245 | 76389353 | I came across this code somewhere when practicing basic C questions:
int func(num) {
if (num > 0) {
return (num + func(num - 2));
}
}
int main() {
printf("%d\n", func(5));
return 0;
}
The code when executed returns 8 as the answer. But I think that the answer should be "cannot be determined".
The recursive calls in my head looks like this:
5 + func(3) => 5 + (3 + func(1))
3 + func(1) => 3 + (1 + func(-1))
1 + func(-1) => 1 + (?)
For the ? symbol, I think reading the return value for func(-1) is undefined behavior. I'm basing this on the assumption that for func(-1) no explicit int value is being returned. So reading from func(-1) in the expression (1 + func(-1)) should produce some garbage result + 1 in my opinion.
Why is that the code is returning 8 as the answer and not something garbage?
When I explicitly pass a negative number to func and read the result I do get the garbage value, such as in this code;
int main() {
printf("%d\n", (1 + func(-1))); // returns garbage result and not 0
return 0;
}
Why is that in the recursive call (1 + func(-1)) is being evaluated to 0 value?
I compiled the code on a 64-bit machine with gcc as gcc myfile.c. Compiling the code as gcc -W -Wall -ansi -pedantic myfile.c gives warning about the func function, but that's not the point. I am unable to figure out how 8 is the answer.
| Why garbage value is not being returned in a recursive call to a function with undefined behavior? |
Why garbage value is not being returned in a recursive call to a function with undefined behavior?
Because "garbage" does not mean what you think it means in this context. In particular, "garbage" does not mean "random". (Or if it does, it's more in the sense of xkcd 221.)
Computers are usually deterministic. You have to work pretty hard to get truly random behavior. Even a program that contains the worst kind of undefined behavior will quite often return exactly the same strange and indeterminate number every time you run it.
I have used this analogy:
Suppose you go to the store and buy a brand-new garbage can. But it's completely clean! There's no garbage in it at all! It's so clean you could eat out of it! Was this false advertising? Did the store fraudulently sell you a non-garbage can?
See more discussion at these previous questions:

(Most of those are talking about the values of uninitialized local variables, not the values of functions that fail to execute a proper return statement, but the arguments are the same.)

76382933 | 76388472 | I am on thin ice both syntax-wise and English-wise here, apologise if my way of expressing maths here is a rambling of a mad-man.
I have two sequences/"functions" f(n) and g(n). They are technically not functions, I have them just defined as a sequence of repeating modulus of 9 and 10.
n = 0,1,2,3,...
f(n): nMOD9={0,3,4,6}
g(n): nMOD10={0,3,4,5,8,9}
This means that f(n) is will go 0,3,4,6,9,12,13,15,18,ect. Just repeating the four numbers in the brackets of modulus of 9.
g(n) will be 0,3,4,5,8,9,10,13,14,15,18,19,20,ect. Repeating the six numbers in brackets of modulus of 10.
Now I wonder, can I express h(n) which is the list of numbers that is both present in f(n) and g(n)? This will be 0,3,4,9,13,15,18,ect. Either as a function or as some nMODx={a,b,c}? Or some other genius way I have not thought about.
Currently I do a manual check of both list, and I wonder if can be done more elegant.
| How to express h(n) which is the "union" of the two sequences f(n) & g(n) | One possible solution would be to find all values of h(n) up to 90, then h(n) will be those nMOD90, so
h(n): nMOD90={0,3,4,9,13,15,18,24,30,33,39,40,45,48,49,54,58,60,63,69,75,78,84,85}

76389296 | 76389365 | According to this statement, pygame.time.Clock().tick() should be called at the end of the main loop. However, I couldn't see any differences on my screen display regardless where I executed that method within the loop. Could someone please give some clarification on this? Thanks
| Where should pygame.time.Clock().tick() be called in the script | The documentation say :
A call to the tick() method of a Clock object in the game loop can
make sure the game runs at the same speed no matter how fast of a
computer it runs on
So it is better to call it at the end of the loop because if you do it in the middle of your display fonction, a part of the element will be refresh before the wainting and a part after.You should call pygame.display.update() before that otherwise you refresh the screen after the "frame wait time".

76382654 | 76388806 | I'm trying to implement on-behalf-of user flow for Microsoft Graph API. I'm using Microsoft Graph .NET SDK and I'm encountering Access Denied (status code 403) for my requests. I'm not sure how to correctly set up permissions for users of my organization in Active Azure Directory. I'm trying to implement SharePoint / OneDrive file operations like list files/download/upload etc. with on-behalf-of flow. I want to be able to access any drive/site files and be able to upload/download/list.
The way my application is designed is like this:
But instead of Desktop WPF app, I have next.js website using next-auth. This is how I define my Azure Active Directory provider to sign-in in my next.js application using next-auth:
providers: [
AzureADProvider({
clientId: process.env.AZURE_AD_CLIENT_ID, // NextAuth client id in AAD
clientSecret: process.env.AZURE_AD_CLIENT_SECRET, // NextAuth client secret value in AAD
tenantId: process.env.AZURE_AD_TENANT_ID,
authorization: {
params: {
scope: "openid email profile offline_access api://NextAuthAPI/.default",
prompt: "consent",
}
},
}),
]
In my AAD I registered my frontend app and web api as NextAuth and NextAuthAPI, generated client secret for both of them. For the NextAuthAPI (webAPI) I created a scope:
and added these permissions:
For the NextAuth (next.js) app I added this permission:
After signing in my next.js frontend application, I'm able to receive an access token with:
"aud": "api://NextAuthAPI",
"scp": "access_as_user"
....
Then I provide this access_token to the webAPI and create client like this:
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "c0dc-------------------5ce7";
var clientId = "087e66-----------------------b5";
var clientSecret = "p5Q8Q-----------------------JddpK";
// using Azure.Identity;
var options = new OnBehalfOfCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
var oboToken = /* HERE I PASTE ACCESS_TOKEN FROM NEXTJS APP */;
var onBehalfOfCredential = new OnBehalfOfCredential(tenantId, clientId, clientSecret, oboToken, options);
m_GraphClient = new GraphServiceClient(onBehalfOfCredential, scopes);
Now, when I have the m_GraphClient initialized, I'm trying to make some requests. This request works for me:
var response = await m_GraphClient.Me.GetAsync();
But something like this:
var response2 = await m_GraphClient.Sites.GetAllSites.GetAsync();
throws an ODataError exception with status code 403 and message "Access denied".
Packages I use:
Microsoft.Graph 5.11.0 (backend)
Azure.Identity 1.9.0 (backend)
Next.JS 13.4.5-canary.2 (frontend)
next-auth 4.22.1 (frontend)
| Microsoft Graph .NET SDK on-behalf-of flow returns Access Denied 403 for Sites/Files | You want to be able to access any drive/site files and be able to upload/download/list. Then on-behalf-of flow isn't suitable for you. OBO flow will generate access token with Delegated API permission, which can't be used to access any others' drive/site files. We need to use access token with Application API permission.
Then in this scenario, we can only use client credential flow so that we can generate access token with Application API permission. First, grant application API permission in Azure portal. For example, we are trying to use this Graph API.
Then in your API application, your code should look like this which used ClientSecretCredential instead of your OnBehalfOfCredential:
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "tenant_id";
var clientId = "client_id";
var clientSecret = "client_secret";
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);

I can't make changes to inner sql query as the source table is of clob data type. What changes should I make to outer query.
| Clob Issues- Splitting a clob column to multiple rows | The code you posted will get that error if the source text is a CLOB, whatever the length. The problem isn't the length itself, it's that each split row value is also a CLOB, and you can't use distinct with CLOBs.
The use of distinct is often a sign that there's a deeper problem that's just covering up. Without it you do get duplicates, but that's a well-known issue with connect-by queries against multiple source rows, and will get progressively worse with more rows.
You need to limit the connect-by to the same source row, which is simple assuming keyvalue is unique; but you also need to introduce a non-deterministic function call to prevent it ballooning the results, for example:
CONNECT BY instr(text, 'Customer Input', 1, level - 1) > 0
AND keyvalue = PRIOR keyvalue
AND PRIOR dbms_random.value IS NOT NULL

76383547 | 76389112 | On an isolated network (without internet access to do public IP address lookups), I want to run a playbook from a controller against a number of target hosts where one of the tasks is to download a file via HTTP/HTTPS from the controller without hard-coding the controller IP as part of the task. E.g.
Controller: 192.168.0.5
Target 1: 192.168.0.10
Target 2: 192.168.0.11
Target 3: 192.168.0.12
The controller can have different IPs configured via DHCP, and there could be multiple network interfaces listed in ansible_all_ipv4_addresses (some of which may not be available to the target hosts) so it may not be straight forward to determine which network interface the target hosts should use from ansible_facts on localhost without exploring the idea of looping through them with a timeout until the file has been downloaded. It seems as though the most robust way to determine the public IP of the controller (assuming the web server is listening on 0.0.0.0) would be to determine the originating IP of the established connection (192.168.0.5) from the target host - is there a way to do this?
The motivation for downloading the file from the controller rather than sending it to remote hosts is that some of the target hosts are running Windows and the win_copy module is incredibly slow via WinRM so the Ansible documentation includes the following note:
Because win_copy runs over WinRM, it is not a very efficient transfer
mechanism. If sending large files consider hosting them on a web
service and using ansible.windows.win_get_url instead.
| How can I get Ansible client IP from target host? | Limited test on my machine which has a single ip and with a single target. But I don't see why it would not work in your scenario.
Given the following inventories/default/hosts.yml
all:
hosts:
target1:
ansible_host: 192.168.0.10
target2:
ansible_host: 192.168.0.11
target3:
ansible_host: 192.168.0.12
The following test playbook should do what you expect. Replace the dummy debug task with get_url/uri to initiate the download.
Notes:
this playbook infers you have access to the ip command line tool on the controller.
I took for granted that the controller IP used to connect to target is the one that the target has access to in the other direction. If this isn't the case then the below will not work in your situation.

I want to map through the array, checking if the data key contains more than 4 numbers and if so, I want to extract the first 4 numbers (each data key is the same in all objects) and put it into a new object key "data" and the date key should look like the first item of the original array. The rest of the data key (in this example [4,2] should go into a new array that will be filled up with 0s until the data's length is 4. The date key of this should contain the date in 4 weeks starting from the first date.
I want to modify it so the result will be like this:
[{
data: [ 5, 2, 7, 2 ],
date: {
begin: '29.05.',
beginYear: '2023',
end: '05.06.',
endYear: '2023',

}
},
{
data: [4, 2, 0, 0 ],

beginYear: '2023',
end: '03.07.',
endYear: '2023',
timestamp: 1687730400000
}
}
]

76382277 | 76389186 | I am using PHP 8.2 to read our JFrog Artifactory API and this works fine. Now I am in the need to either create or update some of the properties on an artifact - so either create it if it does not exists, and update it if it does exists.
For example I can read all properties for a specific artifactory with this code:
<?PHP
// The full URL for the specific artifact and its "properties"
$api = "https://mysrv/api/storage/TestProduct/TestComponent/1.0.0/?properties";
$ch = curl_init($api);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"X-JFrog-Art-Api: ". $artifactoryKey,
));
// Execute the request to retrieve existing properties
$response = curl_exec($ch);
echo "<pre>";
var_dump($response);
?>
This will dump something like this:
string(123) "{
"properties" : {
"ComponentName" : [ "TestComponent" ],
"ContactEmail" : [ "[email protected]" ],
"ContactName" : [ "John Doe" ],
"VersionNumber" : [ "1.0.0" ]
},
"uri" : "https://mysrv/api/storage/TestProduct/TestComponent/1.0.0"
}"
Now I want to create a new key/value pair inside the properties.
For example if I want to create a new key named MyKey with a value of False then I would like to see this result:
string(123) "{
"properties" : {
"ComponentName" : [ "TestComponent" ],
"ContactEmail" : [ "[email protected]" ],
"ContactName" : [ "John Doe" ],
"VersionNumber" : [ "1.0.0" ]
"MyKey" : [ "False" ]
},
"uri" : "https://mysrv/api/storage/TestProduct/TestComponent/1.0.0"
}"
I have of course tried various solutions like:
// Define the new key/value pair
$newProperty = array(
'key' => "MyKey",
'value' => "False"
);
// Prepare the JSON payload
$payload = json_encode(array("properties" => array($newProperty)));
// Initialize cURL to update the properties
$ch = curl_init($api);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'X-JFrog-Art-Api: ' . $artifactoryKey
));
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
// Execute the request to update the properties
$response = curl_exec($ch);
echo "<pre>";
var_dump($response);
... and various tweaks to this but I cannot get it to work. Doing the above solution will give me this error:
string(98) "{
"errors" : [ {
"status" : 400,
"message" : "Properties value cannot be empty."
} ]
}"
My account should have anough access to write/modify (I am not the admin but have been told so) but the error message does not look like it is related to permissions either, so any help on this would be appreciated - I expect this may be a simple fix as I have not much experience with handling Artifactory stuff :-)
| How to create/update key/value pair in JFrog Artifactory with PHP and cURL? | Actually I did figure out this myself and it was a stupid/simple mistake. I easily solved this after finding the right help page - I should probably have invested more time in finding this in the first place :-)
Let me show the solution first:
<?PHP
// Full URL for specific artifact and the property to create/update
$api = "https://mysrv/api/storage/TestProduct/TestComponent/1.0.0/?properties=MyKey=False";
// Initialize cURL to create/update the properties
$ch = curl_init($api);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json",
"X-JFrog-Art-Api: ". $artifactoryKey
));
// Execute the cURL request
$response = curl_exec($ch);
// Dump the result
echo "<pre>";
var_dump($response);
// Check if the request was successful
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
var_dump($httpCode);
// Close the cURL session
curl_close($ch);
?>
This code will result in a HTTP Status 204 (No Content) which equals a success and it will create the new propery named MyKey with the value of False. The cURL PUT command will work for both creating it or updating the value.

76387987 | 76388168 | Imagine I have the following SQL table:
| id | price | start_time |
---------------------------
| 1 | 0.1 | 2023-01-01 |
| 2 | 0.3 | 2023-03-01 |
| 3 | 0.2 | 2023-02-01 |
But then I want to query the prices in that table in a way that I can also get the end time as the start time of the next in time column. So, as an example, if I want to query all the entries in the table I would get something like this:
| id | price | start_time | end_time |
----------------------------------------
| 1 | 0.1 | 2023-01-01 | 2023-02-01 | // end_time = start_time of the next entry
| 3 | 0.2 | 2023-02-01 | 2023-03-01 |
| 2 | 0.3 | 2023-03-01 | |
But, I would also like to query that table with others filters, as an example, all entries whose prices are lower than 0.25, then I expect:
| id | price | start_time | end_time |
----------------------------------------
| 1 | 0.1 | 2023-01-01 | 2023-02-01 |
| 3 | 0.2 | 2023-02-01 | 2023-03-01 | end_time = start_time of entry with id 2
So even that the entry with id 2 is filtered out, its start_time is still used as end_time of one of the entries.
Is this possible to achieve with one single query? I am bit lost on how to solve this approach without doing multiple queries.
| Get the end_time in a query using the start time of the next sorted column | This can be done using the window function lead() to get the which follows the current row :

Image of the Result:
| useState() not updated when state is used in a loop | In React, components have a lifecycle that is based around the idea of preserving state. When you update a value in a component we effectively trigger a re-render of the component. So if you have a variable at the top of your component with a certain value and try to update this value inside a function, you'll find that this value gets reset. React is replacing the component including the JavaScript variables inside it.
In order to preserve any variables we use useState to persist the state of the component between re-renders. However, in a function, using useState does not save the value to state immediately. useState is an instruction that is sent to React that tells it that when the component re-renders, we need to save that value. If you try to access the value in state before your re-render has begun you will be using the "previous" value instead. In your case, your component will not re-render until the calling function has been completed.
So how do you listen for changes?
UseEffect is a special hook that takes an array of dependencies as "listeners". When we use useEffect and give it a value in state as a dependency, it's telling it to run the code inside the useEffect if there is a mutation to that value.
useEffect(() => {
rolesData.map((item, index) => {
console.log(item.checked + " ^ " + item.name);
});
}, [rolesData]);
This code will run every time myState is changed, including on component initialisation. So we can use useEffect to process logic that requires the newly updated stateful values.

76389309 | 76389422 | I am trying to write a Python regex pattern that will allow me to capture words in a given text that have letters separated by the same symbol or space.
For example, in the text "This is s u p e r and s.u.p.e.r and sπuπpπeπr and s!u.p!e.r", my goal is to extract the words "s u p e r", "s.u.p.e.r", and sπuπpπeπr. However, I want to exclude "s!u.p!e.r" because it does not have the same consistent separating symbol within the word.
I'm currently using the following:
x="This is s u p e r and s.u.p.e.r and sπuπpπeπr and s!u.p!e.r"

final multiplier = (translate > 0 ? 1 : -1);
final goal = _calculateGoal(mediaWidth, multiplier);
final Tween<double> tween = Tween(begin: translate, end: goal);
final animation = tween.animate(animationController);
animation.addListener(() {
setState(() {
translate = animation.value;
});
});
} else {
final animation = Tween<double>(begin: translate, end: 0).animate(animationController);

}

}
void reveal(RevealSide direction) {
// can only reveal when showing main
if (translate != 0) {
return;
}
final mediaWidth = MediaQuery.of(context).size.width;
final multiplier = (direction == RevealSide.left ? 1 : -1);
final goal = _calculateGoal(mediaWidth, multiplier);
final animationController = AnimationController(vsync: this, duration: const Duration(milliseconds: 200));
animationController.addStatusListener((status) {
if (status == AnimationStatus.completed) {
_onApplyTranslation();
animationController.dispose();
}
});
final animation = Tween<double>(begin: translate, end: goal).animate(animationController);

animationController.forward();
}
void onTranslate(double delta) {
setState(() {
final translate = this.translate + delta;
if (translate < 0 && widget.right != null || translate > 0 && widget.left != null) {
this.translate = translate;
}
});
}
@override
Widget build(BuildContext context) {
return Stack(children: [
Offstage(
offstage: translate < 0,
child: widget.left,
),
Offstage(
offstage: translate > 0,
child: widget.right,
),
Transform.translate(
offset: Offset(translate, 0),
child: widget.main,
),
widget.allowSidePanel
? GestureDetector(
behavior: HitTestBehavior.translucent,
onHorizontalDragUpdate: (details) {
onTranslate(details.delta.dx);
},
onHorizontalDragEnd: (details) {
_onApplyTranslation();
},
)
: SizedBox(),
]);
}
}
Now you can use also the variable 'allowSidePanel' in your code. And If you update your code to:
class TestScreen extends StatefulWidget {
const TestScreen({super.key});
@override
State<TestScreen> createState() => _TestScreenState();
}
class _TestScreenState extends State<TestScreen> {
ScrollController controller = ScrollController();
bool allowScroll = false;
@override
void initState() {
super.initState();
// Setup the listener.
controller.addListener(() {
if (controller.position.atEdge) {
bool atBegin = controller.position.pixels == 0;
if (atBegin) {
/// here you can later allow left panel later
} else {
/// here allow sidepannel
setState(() {
allowScroll = true;
});
}
}
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: MyOverlappingPanels(
allowSidePanel: allowScroll,
right: Builder(builder: (context) {
return Text("right");
}),
main: Builder(
builder: (context) {
var items = ["item1", "Item2", "Item3", "Item4", "Item5", "Item6", "Item7"];
return Container(
width: double.infinity,
height: 200,
color: Colors.blue,
child: ListView.builder(
controller: controller,
scrollDirection: Axis.horizontal,
itemCount: items.length,
itemBuilder: (BuildContext context, int index) {
return Container(
width: 150,
margin: const EdgeInsets.all(8),
child: Container(
padding: EdgeInsets.all(8),
color: Colors.red,
child: Center(
child: Text(
items[index],
style: const TextStyle(color: Colors.black, fontSize: 18),
),
),
),
);
}));
},
),
onSideChange: (side) {
setState(() {
if (side == RevealSide.main) {
/// here deaktivate ssidepannel again
allowScroll = false;
} else if (side == RevealSide.left) {
// show something
}
});
},
),
);
}
}
this will work.

76390731 | 76390810 | I'm parsing a list of emails in a text file and I need to parse dates in the email headers. The dates are in a multitude of formats and languages:
sexta-feira, 26 de agosto de 2022 16:41
viernes, 26 de agosto de 2022 19:24
2022/08/26 13:30:56
26 de agosto de 2022 13:32:49 BRT
Mostly portuguese, spanish, italian and english.
What would be the best aproach? I have tried Babel but the date parsing is very basic. For now I only have access to the text files exported from Outlook not the smpt sources.
| Parsing multiple date string languages and formats | The dateparser package provides modules to parse localized dates in most string formats.
The following snippet successfully retrieves all dates in the given example:
import dateparser
text_dates = [
"sexta-feira, 26 de agosto de 2022 16:41",
"viernes, 26 de agosto de 2022 19:24",
"2022/08/26 13:30:56",
"26 de agosto de 2022 13:32:49 BRT",
]
datetimes = [dateparser.parse(line) for line in text_dates]
print(datetimes)
>>> [datetime.datetime(2022, 8, 26, 16, 41),
datetime.datetime(2022, 8, 26, 19, 24),
datetime.datetime(2022, 8, 26, 13, 30, 56),
datetime.datetime(2022, 8, 26, 13, 32, 49, tzinfo=<StaticTzInfo 'BRT'>)]

76389259 | 76389434 | Consider the MWE below
WITH samp AS (
SELECT '2023-01-01' AS day, 1 AS spent UNION ALL
SELECT '2023-01-02' AS day, 2 AS spent UNION ALL
SELECT '2023-01-03' AS day, 3 AS spent
)
SELECT day,
spent
, ARRAY_AGG(spent) OVER(ORDER BY day BETWEEN '2023-01-02' AND '2023-01-03') ss
FROM samp
ORDER BY day
I cannot figure out what the order by clause is doing here. I'd expect to restrict the entries to those of the selected dates, but dates outside it also have a contribution? E.g., outcome of the above
day
spent
ss
'2023-01-01'
1
[1]
'2023-01-02'
2
[1,2,3]
'2023-01-03'
3
[1,2,3]
| Window function, order by clause, between operator | The clause
day between '2023-01-02' and '2023-01-03'
is a boolean expression, and will only evaluate to two possible values, true or false (1 or 0). Therefore, your window function array_agg(spent) will compute using an order where dates other than 2023-01-02 and 2023-01-03 will be ordered first, followed by these dates next.
Here is your updated output showing the ordering logic:
day spent ss order (day between ...)
'2023-01-01' 1 [1] 0
'2023-01-02' 2 [1,2,3] 1
'2023-01-03' 3 [1,2,3] 1

76389304 | 76389435 | The username is in column one and PID in column two of ps gaux, so I have:
ps gaux | awk '{print $2;}' | while read line ; do grep -i umask /proc/$line/status ; done
but is there a way to print the username as well?
| How do I print the user and umask for all running processes? | I hope this helps
ps gaux | awk '{printf $1 " " ; system("grep Umask /proc/"$2"/status | tr -dc [:digit:]"); printf "\n"}'
Explanation:
get output from ps
print first column (username) and space
run the grep and remove everything except the actual umask, which is a number (awk does not print the command output, it gets just printed directly from the subshells stdout)
print a new line

76383190 | 76390828 | I am getting this error:
IntegrityError at /register/
null value in column "total_daily_mission_progress" violates not-null constraint
DETAIL: Failing row contains (363, 0, 374, free, 0, null, unranked, 0, , [email protected], 0, f, [], 0, {}, {}, t, null, null, null, null, null, {}, null, null, No phone number set, This user has not set a description yet., /static/images/profilepictures/defaultavatar.png, {}, {}, {}, {}, {}, 0).
However, the column total_daily_mission_progress no longer exists in my UserDetail model. I deleted it a while ago and migrated. However, this issue comes up every time I try to create a new UserDetail model.
Why is this occuring? I don't have the total_daily_mission_progress anywhere in my code. And how can I fix it?

76389341 | 76389488 | I am trying to do some text processing and was interested to know if I can have a common/unified regex for a certain pattern. The pattern of interest is strings that ends with {string}_{i} where i is a number, on the second column of test.csv. Once the regex is matched, I wish to replace it with {string}[i].
For now the python script works as expected for the strings for which I explicitly mention the regex pattern. I want to have a more generic regex pattern that will match all the strings that have {string}_{i} instead of writing a regex for all the patterns (which is not scalable).

76390640 | 76390875 | I have two 3D masked arrays (netCDF4 files output from climate model) that I want to add together. I followed this thread and got the following (simplified) code out of it:

I have also tried to add the arrays together using a for-loop, but somehow couldn't get that to work without losing a dimension and the majority of the array elements of the data.

I don't understand, why I am getting the compiler error, when the code is functionally the same?
Consider this case:
public struct Awkward : IMyInterface
{
}
...
Mock<Awkward> mock = MockFactory.CreateMock<Awkward>();
That satisfies the constraint you've put on CreateMock - but Awkward is a value type. Mock<T> requires T to be a reference type.
You need to constrain the T type parameter in your method to be a reference type that implements the interface:

| How to copy from byte[] to new byte[] with some changed element item? | You should perform the operations the other way round. First copy then change the value in the copied data. This way the original will stay unchanged.
Efficient:
var original = new byte[]{1,2,3};
var result = new byte[original.Length];
Array.Copy(original, result, original.Length); //first make a copy
result[2] = 42; //then set your new value
//result is now [1, 2, 42]
Simple with LINQ:
//do not forget using System.Linq;
var original = new byte[]{1,2,3};
var result = original.ToArray(); //first copy
result[2] = 42; //then set your new value
//result is now [1, 2, 42]
For small data there will be no difference in performance. For large arrays the direct copy should perform a bit better. See this answer for further alternatives regarding the copy part.

76387972 | 76388288 | I want to use clip-path to implement effect like: svg with text clip-path, but open in browser it just display an empty
svg. I wrap the path with <g> tag, then it failed.

</g>
<style>
text {dominant-baseline: hanging;font-size: 8px;font-weight: bold;}
</style>
</svg>
it should be displayed in browser.
| How can I use clip-path to achieve a text effect on my SVG in the browser? | In your example (above) you may remove the wrapping group around the 2 paths and the text and it would work.
<clipPath id="text-path">
<!-- <g clip-rule="evenodd" fill-rule="evenodd"> -->
<path d="M0 0H14V2H2V13H22V10H24V13H32V27H24V32H0V0ZM2 30V27H22V30H2Z"/>
<path d="M16 0L24 8H16V0Z"/>
<text x="7.5" y="23">PDF</text>
<!-- </g> -->
</clipPath>
However you won't see the text.
If what you need is to see the text as a hole in the shapes you will need a mask where the text is black and the 2 paths are white. In the case of the mask you can use a group if you think you need it.

76390686 | 76391032 | <template>
<v-list-item v-for="(category, i) in categories" :key="i">
<v-item-group multiple @update:model-value="selectedChanged(category)">
<v-item></v-item>
</v-item-group>
</v-list-item>
</template>
<script>
function selectedChanged(category) {
return function(items) {
console.log(`select ${items} from ${category}`);
}
}
</script>
I hope that, in function selectedChanged, I can know which category was selected. But it doesn't work. Vue just called selectedChanged with parameter category.
The reason why I want to do this is that, if I define selectedChanged as follows:
function selectedChanged(items) {
console.log(items);
}
I don't know which category was selected.
How to impelement function selectedChanged so that I can know which category was selected?
| Vuejs. is it possible to pass a function returned from another function to event handler? | Like Estus said in the comments, it looks like what you want can probably be achieved by explicitly passing $event as one of your event handler arguments. (Here is a link to the relevant Vue 3 documentation on $event.) The code would look something like this:
<template>
<v-list-item v-for="(category, i) in categories" :key="i">
<v-item-group multiple @update:model-value="selectedChanged(category, $event)">
<v-item></v-item>
</v-item-group>
</v-list-item>
</template>
<script>
function selectedChanged(category, items) {
console.log(`select ${items} from ${category}`);
}
</script>
Of course, this solution assumes that the items you're looking for are emitted by the update:model-value call in (what I assume to be) Vuetify. You might need to do some destructuring or refactoring to get precisely what you want.

76389651 | 76389684 | I am trying to implement Job Shop Scheduling with CP-SAT, but I have more than 20000 tasks to schedule and finding optimal solution will take too much time. I'm using solver time limit, but sometimes it gives me feasible solution in assumed time and sometimes not. Could anyone show how to limit solver to find the first feasible solution?
https://developers.google.com/optimization/scheduling/job_shop
I know that I should use SolveWithSolutionCallback, but I don't know how.

76387879 | 76388302 | Using JSONATA, is it possible to exclude certain fields that are nested in a deep structure without using object construction? For example, with the following object
{
"collection": [
{
"id": "ABC",
"learningunit": {
"metadata": {
"show": true,
"unitType": {
"code": "U",
"value": "Unit"
}
}
}
},
{
"id": "UYE",
"learningunit": {
"metadata": {
"show": false,
"unitType": {
"code": "C",
"value": "COURSE"
}
}
}
}
]
}
can we exclude the field "show" and "value" in order to get the following result.
{
"collection": [
{
"id": "ABC",
"learningunit": {
"metadata": {
"unitType": {
"code": "U"
}
}
}
},
{
"id": "UYE",
"learningunit": {
"metadata": {
"unitType": {
"code": "C"
}
}
}
}
]
}
FYI, the following object construction expression does the job but it is cumbersome to write if the object is complex.
{"collection":collection.
{
"id": id,
"learningunit": learningunit.
{
"metadata": metadata.
{
"unitType": unitType.
{
"code": code
}
}
}
}
}
| Is it possible to exclude certain fields using JSONATA? | You can make use of the transform operator and remove all 'value' and 'show' fields from the nested structure:
$$ ~> | ** | {}, ['show', 'value'] |
See it on the live Stedi playground: https://stedi.link/Usc1tpg
Note that if you need to clear those on a specific path only, you can also do it more surgically:
$$
~> | *.learningunit.metadata | {}, ['show'] |
~> | *.learningunit.metadata.unitType | {}, ['value'] |
