Instead of relying on my host to send an email, I was thinking of sending the email messages using my Gmail account. The emails are personalized emails to the bands I play on my show.   Is it possible to do it?

What are Null Pointer Exceptions (java.lang.NullPointerException) and what causes them?  What methods/tools can be used to determine the cause so that you stop the exception from causing the program to terminate prematurely?

I actually do want to know how to generate the multiplication inverse (M.I) table, I mean the calculation how the M.I been generated.. such as the M.I of 22 is 5A regarding to the table.. Do you know how to calculate M.I how the 22 will become 5A

I know how to do multiplication over ${\rm GF}(2^8)$:  uint8_t  gmul(uint8_t  a, uint8_t  b) {     uint8_t p=0;     uint8_t carry;     int i;     for(i=0;i<8;i++)     {         if(b & 1)             p ^=a;         carry = a & 0x80;         a = a<<1;         if(carry)             a^=0x1b;         b = b>>1;     }     return p; }   So, I tried to create a ${\rm GF}(2^8)$ multiplication table using this code. I've given below the values in the 3rd row of the table, but I don't think they're correct:      0  1  2  3  4  5  6  7   8  9  A  B  C  D  E  F 0 1 2   0  2  4  6  8  A  C  E  10 12 14 16 18 1A 1C 1E  3 . . E F   I don't know what went wrong. I built the table by multiplying the values in the first row with those in the first column.  E.g. in the third row, I multiplied 2 × 0, 2 × 1, …, 2 × E, 2 × F.  How can I create a multiplication table for arithmetic in ${\rm GF}(2^8)$?    Also, how can I find the multiplicative inverse of a number in ${\rm GF}(2^8)$?  For example, how can I determine that the inverse of 95 is 8A?  I tried to do this using the multiplication table above, but when I took 9th row and the 5th column in the multiplication table I got 2D, not 8A.


Me and my friend try to solve   $${{z}^{3}}=\overline{z}$$  where $z \in \mathbb{C}$.  My way to solve it was:  $\operatorname{cin}(\theta )=\cos(\theta)+\sin(\theta)i$  \begin{align}   & z=r \operatorname{cin}(\theta ),\overline{z}=r\operatorname{cin}(-\theta +2\pi k) \\   & {{z}^{3}}={{r}^{3}}\operatorname{cin}(3\theta ) \\   & {{z}^{3}}=\overline{z} \\   & {{r}^{3}}\operatorname{cin}(3\theta )=r\operatorname{cin}(-\theta +2\pi k) \\   & {{r}^{3}}=r\Leftrightarrow {{r}^{3}}-r=0\Leftrightarrow r({{r}^{2}}-1)=0\Leftrightarrow r=\pm 1,r=0\Leftrightarrow r=1 \\   & 3\theta =-\theta +2\pi k\Leftrightarrow 4\theta =2\pi k\Leftrightarrow \theta =\frac{\pi k}{2} \\  \end{align}  So my solution for k=0,1,2 :  $\begin{align}   & {{z}_{1}}=\cos (0)+\sin (0)i=1+0i \\   & {{z}_{2}}=\cos (\frac{\pi }{2})+\sin (\frac{\pi }{2})i=0+1i \\   & {{z}_{3}}=\cos (\pi )+\sin (\pi )i=-1+0i \\  \end{align}$  My friend on the other hand solve it like this:  $\begin{align}   & {{z}^{3}}=\bar{z} \\   & {{z}^{3}}\cdot z=\bar{z}\cdot z \\   & {{z}^{4}}=|z{{|}^{2}} \\  \end{align}$   He got the same solutions expect he got one more solution than me  ${{z}_{4}}=\cos (\pi )+\sin (\pi )i=0-i \\$   What is the right solution and why?

We have the following equation:  $$z^3 = \overline{z} $$  I set z to be $z = a + ib$ and since I know that $ \overline{z} = a - ib$. I was trying to solve it by opening the left side of the equation.  $$ z^3 = (a+ib)^3 \Rightarrow $$ $$ [a^2+b^2+i(ab + ba)](a+ib) \Rightarrow $$ $$ a^3 - b^2a - 2b^2a + i (2a^2b + b^2a - b^3) $$  but this is where I got so far and I'm not sure how continue and if my solution so far is even the right way to solve it.

Edit/Summary: I will not have physical access to the computer for the next month (it's at my parent's house and I live abroad), but from reading the comments, I believe a deep cleaning of the internals is a great suggestion, and I will as soon as I get back. I will also replace the MB battery, though the latter seems fine (read below for details). But if you have any proposed solutions that don't require physical access, please express them as I do have Teamviewer access.  I'm having a very weird issue where my computer instead of shutting down will blink for around 3-5 seconds (the sleep-state slow blink) and then it will start up/wake up again on its own. The same happens when I choose to "Sleep".  Things I have tried:   Resetting Windows 10 using the Troubleshoot at boot Resetting BIOS settings to default (disabled wake on LAN) Updating all drivers. BIOS last official update Dec. 2015. Installed since early 2016 Disallowing Wake Events to wake PC. Disabling Hibernate/Hybrid Sleep Checked all devices in Device Manager and disabled Allow device to wake computer when available (only the LAN driver had such an option). Removed all cables except mouse/keyboard/monitor. (no wifi) Checked the physical Power Button Disabled Windows Maintenance Activator and manually ran the maintenance tasks powercfg waketimers returns nothing powercfg -DEVICEQUERY wake_armed returns NONE Unfortunately I had System Restore disabled so I cannot restore to a previous point Threw away my very weak UPS and connected directly to power strip Cleaned the graphics card because its position seemed kind of odd. Rest of the insides have been last cleaned in December Checked condition of motherboard battery: it's fine (after draining the capacitors and cutting power to the PSU for a minute, system time is still correct (50ms ahead)). I will replace it anyway when I get back.   The issue still persists.  When I run powercfg /lastwake I get nothing useful (no wake source), and when browsing Event Viewer, I get Wake Source: Unknown.  Now I'm simply out of ideas. Could it be some kind of motherboard issue? This computer is 10+ years old (battery works fine), but it has been running Windows 10 fine since it came out, and the BIOS was last updated 2015.  Edit: I believe this question is not a duplicate of the one suggested because of two reasons: - I have already read the whole post and the proposed solutions did not help my case. - The duplicate answer suggested has no mention of shutdown issues: only sleep is mentioned. - My issue occurs only seconds after sleep/shutdown regardless of time, suggesting that a scheduled task is not the issue. Therefore I believe that a different answer/solution is applicable.

I have an interesting problem. I am using Windows 8.1 on my PC and I have WOL enabled from my BIOS and my LAN card settings and it works just fine.  But, since a couple of weeks back, my computer turns on by itself in the middle of the night.  Two nights ago, after it woke me up because of the noise, I removed the LAN cord and everything was well until the next morning when I powered the PC myself. I also thought it could be a peripheral, so from Device Manager I went through every device there (apart from the LAN card, which I need because of the WOL), disabling Allow device to wake the computer from "Power Management". Also, in the LAN settings, I checked and the network card can be wake the PC up just by using Magic Packet or Pattern Mach.   The problem persisted last night (it woke around 5am).  I started reading forums and saw the idea of looking what last turned on my PC, so I checked with powercfg -lastwake and it returned the following:   Wake History Count - 1 Wake History [0]  Wake Source Count - 0   Because of the answer, I couldn't find a thing, therefore I checked the Windows logs, filtering them by Power Issues. I found the last wake my PC  experienced, and the log was as it follows:   The system has returned from a low power state. Sleep Time: 2014-05-08T23:38:33.848063300Z Wake Time: 2014-05-09T01:56:48.134397800Z     Wake Source: Unknown   This is the reason I have posted the issue here, even though there are many posts about this. I didn't want to repost, but I never found this same problem (with wake source unknown) in any post or forum.  I hope someone has an idea of what may be the problem.


In the following sentence:  They can disagree.  what I want to say is that the subject, they, can possibly reach a state when they no longer agree. Of course, it can be the opposite - they can agree with each other and live happily ever after, but I'd like to specifically underline the chance for the negative outcome. So what I did is I took an antonym for verb "agree", disagree, and this was all I needed to build this very simple sentence. So far so good. But what if I have a verb that doesn't have a simple antonym (or I just forgot this antonym and I need to come up quickly with a grammatical construct to compensate this)? Such as negotiate. Obviously, I can't say "they can not negotiate", because in English, "X can not Y" doesn't mean "X can possibly reach a state when X doesn't Y". It means "X won't do Y, never ever". But what should I do, then? I can probably put a filler word between "can" and "not" to break this pattern, such as:  They can possibly not negotiate. / They can possibly not agree.  But is it correct, is it idiomatic English?

Note: make sure you distinguish "make suggestions" & "ask for suggestions"     -make suggestions: eg: you could stay at home if it rains      -ask for suggestion: eg: "Where shall I put the vegetables?"   It seems that some resources say ""  Eg:   What shall I do with these boxes?  Where should I put the vegetables?  But, this dictionary talks about      Could: used in speech to make a polite request or suggestion .... “Where can I stay?” “Well, you could always stay with me.”   They say "could to make suggestions" & they don't say "could to ask for suggestions"  We can use "could" to make suggestions, eg: you could try glue if tape doesn't work  So, in this example      A: “Where can I stay?”       B: “Well, you could always stay with me.”   could in "you could always stay with me.” make a suggestion, but see the “Where can I stay?”, it seems that can in this case is asking  for a suggestion.  My question is:  can we use "can", "could", "may" & "might" to ask for suggestions"?


Hello i'm still kind of new to java.. I get the concept of "this" when it comes to instance variables but when i use it in a constructor with no parameters i get a little confused. So my question is how does something like this work?   private double x; private double y;  public static final double EPSILON = 1e-5; public static boolean debug = false;   public Point(double x, double y){     this.x=x;     this.y=y;  // Done sets the x,y private types to the x,y type provided in the () }  public Point(){     this(0.0,0.0);  //Sets, x and y to doubles of 0.0,0.0??  }                   //How does this work?    Would my point() constructor create an origin of (0.0,0.0) by calling the point (x,y) constructor? Any clarification on this would help me out a lot!

Is it possible to call a constructor from another (within the same class, not from a subclass)? If yes how? And what could be the best way to call another constructor (if there are several ways to do it)?


I'm trying to vertically center the content of an inline-block and I can't figure it out. I've tried different options I've found here such as the flex and the transform but none of them worked for me. I'm probably missing something.  The idea is to have several divs (steps) with one image each on the left and some lines on the right, centered vertically.  Any help is appreciated  HTML:

1. Register
Morbi ut egestas urna, et interdum dolor. Duis fermentum orci in nisi egestas, et imperdiet mauris luctus. Praesent vulputate diam

    CSS:  .med-step-wrapper {     width: 95%;     margin: 0 auto; }      .med-step {         width: 100%;     }      .med-step-logo {         width: 33%;              display: inline-block;         padding: 3rem;     }          .med-step-logo img {         width: 100%;                 height: auto;     }         .med-step-text {         width: 66%;         display: inline-block;         font-family: 'DIN1451EngschriftRegular';     }      .med-step-text p {        }

Why won't vertical-align: middle work?  And yet, vertical-align: top does work.   span{   vertical-align: middle; }
      Doesn't work.


I'm trying to do a loop thru all the button text in a form, but i can't find any solution for Java !!  i did something like :   for(JButton temp : this)  {         if(JButton.getText() == "A")         {           JButton.enabled(false);         }  }   but no luck   p.s. my problem is not about the equals statement !! I want to loop thru all button in my window.  here is the working result thanks to MadProgrammer:  for(Component comp : jPanel2.getComponents())              {                 if(comp instanceof JButton)                 {                    JButton btn = (JButton)comp;                                           if(btn.getText().equals("A"))                     {                      btn.setEnabled(false);                     }                 }             }

I've been using the == operator in my program to compare all my strings so far. However, I ran into a bug, changed one of them into .equals() instead, and it fixed the bug.  Is == bad? When should it and should it not be used? What's the difference?


I know this has been  , but I must be missing something.  I want to put a border above all rows that contain "Monday".      The formula is =$B$3="*Monday*"  I thought it might be because the value of the cell is actually "4/18/2016" but I manually changed it to "Monday" and the rule still didn't fire.  What am I doing wrong?

Possible Duplicate:          I have a spreadsheet where I have cell within a row that will contain specific text via data validation. So for instance a cell could contain the text "Due in 7 Days", "Past Due", or "Closed".  I want the row color to change depending on the text that appears in the cell. So if the text "Past Due" appears in the cell I want that entire row to turn red, if "Due In 7 Days" appears the row should turn yellow, and if "Closed" the row would turn gray.  How can I do that?


I am trying to get all file which is reside in one folder and file name have space like  1)File Test 050791.xml   and i am fetching using below command   export srcfileTimeCheck="$(find $dir -type f -mtime +1)"   but this command give me error like   find: can not stat File find: can not stat Test find: can not stat 050791.xml   Please help me how can i find all file which having space also. Note: I Have tried  1) xrags -0 -I '{}'

Or, an introductory guide to robust filename handling and other string passing in shell scripts.  I wrote a shell script which works well most of the time. But it chokes on some inputs (e.g. on some file names).  I encountered a problem such as the following:   I have a file name containing a space hello world, and it was treated as two separate files hello and world. I have an input line with two consecutive spaces and they shrank to one in the input. Leading and trailing whitespace disappears from input lines. Sometimes, when the input contains one of the characters \[*?, they are replaced by some text which is is actually the name of files. There is an apostrophe ' (or a double quote ") in the input and things got weird after that point. There is a backslash in the input (or: I am using Cygwin and some of my file names have Windows-style \ separators).   What is going on and how do I fix it?


I am thinking, that the missing antimatter that was created at the Big Bang can be accounted for if we consider that it went the opposite direction in time (into the negatives)

While I was reading a  asking if other galaxy could be made of antimatter, to which the answer was: if they were, we should detect the radiation from matter interacting with antimatter on that sort of scale. But what if the missing antimatter lies outside the observable universe. Wouldn't that result in the matter dominated observable universe we live in, without any of the radiation from the antimatter lying outside it being detected?


Example:     I had no idea how deep the forest really was, though the people around   often used the word endless to describe it. And I believed that was   the case, for I'd never seen the end of it, not even   standing from the tallest balcony.   Will the meaning change if I use since, instead? I'm not sure why, but I feel using for will make the passage sound a bit "dated"?

I am not a native speaker. On a previous question of mine, I thanked for an answer by saying:     So the phrase is not an idiom, since it is applied in its literal sense.   I consciously chose since over because, because — well, I like that usage of since, even though I know that some (native speakers) don't like it. Nonetheless, that choice got me thinking for a while, and it occurred to me that I even could have used more alternatives, namely as or for, without changing the meaning.   So, on a general note, here are the alternatives:        Statement A (is true), because statement B (is true).   Statement A (is true), since statement B (is true).   Statement A (is true), as statement B (is true).   Statement A (is true), for statement B (is true).      Are these completely interchangeable? Or interchangeable in certain situations? Or can you point out any (not-so-)subtle differences between any of them? Are there even more synonyms?


How to find the solutions of: $$a^2 = [29]_{35}$$ ?  (Brutal) Attempt: Since $Z_{35}$ contains only 35 elements, one could just brute force the calculation of $a^2$ for every element a $\in Z_{35}$ that GCD(a,35). When you find a number that verifies the equation, automatically you find another solution which is the inverse of that solution $\in Z_{35}$.  Do you know any non brutal way?  NOTE: it doesn't have to require the quadratic congruence solving (I have only studied linear congruences)

Find out all solutions of the congruence $x^2 \equiv29 \mod 5$.  [Hint:Find the solutions of this congruence $\mod 5$ , $\mod 7$ , and $\mod 7$ , and then use the Chinese Remainder Theorem.]


I'm not English and I never encountered this saying:     In almost all cases, it is possible and within reason to write   completely portable code.       In practice, this means that you shouldn’t assume much about the host   compiler (and Visual Studio tends to be the lowest common   denominator).   What's the meaning of the "to be the lowest common denominator" in a sentence? That it is a concept that applies for all or something else?  Also: I'm not sure  answers my problem, I read it but couldn't figure out the above sentence appropriately

For example, we could say HTML is the lowest common denominator on the web", because one can be sure all web browsers are able to render HTML (but not Flash or Java). If I want my web page to show properly everywhere, I know I can use maximum set of features shared between all web browsers, i.e. HTML. Yet, we don't say HTML is the greatest common divisor, which would be a correct analogy.   Why is the mathematical term lowest common denominator misused in everyday usage?


My daughter's bike has a 20x2.25 tyre, but they are hard to come by here in NZ. More common is a 20x1.75 tyre. Will this fit? Looking at other posts, and some charts, I think it should work?

We often get questions on bicycles.stackexchange about fitting wider or narrower tires to bicycles. We have a large number of these with answers suiting the specific bike or style of bicycle in question, but I have been unable to find one that provides a generic answer covering off all things that need to be considered. For most bicycles, the answer is the same regardless of the specific style and sizes of tires in question.   This is intended as a canonical question that we can point closed questions to.


Here is my question: I want to know if there is a test that allow me to do an nonparametric ANCOVA. Let me explain: I am looking for a Mann-Whitney-U and a Kruskal-Wallis, but I want to include a categorical (not continuous) covariate into the analysis.

Hi I am trying to find the non-parametric equivalent of a two-way ANOVA (3x4 design) which is capable of including interactions. From my reading in Zar 1984 "Biostatistical analysis" this is possible using a method put forth in Scheirer, Ray, and Hare (1976), however, according to other posts online it was inferred that this method is no longer appropriate (if it ever was).  Does anyone know what method would be appropriate for doing so, and if so the corresponding functions in R or Stata?


I am looking for the solution of the following question.  Let $G ⊂ S_7$ be a subgroup of order 8. Prove that there exists $i ∈\{1,...,7\}$ such that for any $σ ∈ G$ we have $σ(i) = i$  Thank you in advance.

Let the group $G \subset S_7$, $|G|=8$. Show that there exists $i\in{1,...7}$ such that for all $f\in G,f(i)=i$.  I have attempted this problem, but I am not entirely sure if my thinking is correct. Using orbit stabilizer theorem, I write $|G|=|orb_G(i)||stab_G(i)|$, and since $|G|=8, $ then $|stab_G(i)|$ is equal to either $1,2,4,8$ and $|orb_G(i)|$ equal to $8,4,2,1$ respectively. Now, when the order of the orbit is 8 and stabilizer 1, can I conclude that there exists a function that maps $i$ to $i$?  Any help would be appreciated!


Can anyone help creating this table,I can't figure it out.    I tried this code but got some errors:  \begin{tabular}{|c|c|c|c|c|} \hline  something & \multicolumn{4}{ c| }{something} \\  \cline{2-5} & $ t_{1} $ & $ t_{2} $ & ... & $ t_{n} $ \\  \hline \multicolumn{1}{ |c|  }{\multirow{d1} & 1 & 2 & 3 & 4 $ \\ \hline  \end{tabular}   Thanks in advance.

I'm trying to create a table which looks like    but I'm not really sure how to incorporate multiple spanning rows and columns together (to add 'Organism 1' and 'Organism 2'). I've gotten to this point so far:   \documentclass[a4paper,10pt]{article} \usepackage[utf8x]{inputenc} \usepackage{amsmath}  \begin{document} \begin{tabular}{r|c|c|} \multicolumn{1}{r}{}  &  \multicolumn{1}{c}{$S$}  & \multicolumn{1}{c}{$T$} \\cline{2-3} $S$ & $a,a$ & $b,c$ \\cline{2-3} $T$ & $c,b$ & $d,d$ \\cline{2-3} \end{tabular}  \end{document}    And it currently looks like this:    Can anyone suggest how to add the top 'Organism 2' and left 'Organism 1' row/column entries?  thanks!


Two weeks from now (Oct. 22), I will land at Narita airport at 3 P.M. and then transfer directly to Haneda airport for my connecting flight to Manila at 1 A.M. on Oct. 23; this is a 9-hour layover and I have no plan to travel outside of Tokyo for pleasure. The embassy told me to get a transit visa, but is it applicable in my situation? Is there any exemption? I am a Philippine citizen.

I'm going to the Philippines this October and would like to layover in Japan. I found a reasonably priced ticket with a 15-hour layover to Haneda, however, I have to transfer to Narita. Do I need a visa since I'm going to have to stay at a hotel and ride a bus to travel to Narita airport? Thank you!


For some reason, when I press render and I have my output folder set, it doesn't render it there. How can I save my image to the output folder?

I usually am able to render successfully to the c:\tmp folder, but when I came into work today, I rendered out the image on my work laptop, and everything seems to work, but I'm not getting an output to the tmp directory.  Does anyone know how to make this work?


The fighter's Action Surge originally stated:  Starting at 2nd level, you can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action on top of your regular action and a possible bonus action  This mention of "a possible bonus action" has been a source of confusion, as evidenced by this question  and at least four questions that have been marked as duplicates of it. This is no longer the case. Action Surge now says:  Starting at 2nd level, you can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action. Once you use this feature, you must finish a short or long rest before you can use it again.  It is now quite clear that Action Surge does not grant an additional bonus action. But when did this change occur? I have checked the  and it makes no mention of the change. So when did this change occur and was it documented?

The D&D 5e core books were updated with a new printing as of  (alongside the release of the ), as can be seen from  referencing these changes.  Some examples of the new questions:         Most of these changes are noted in the . However, frustratingly, not all of the changes are noted there. (For instance, the phrasing of the fighter's Action Surge feature was simplified, and the description of the clone spell added a significant word.)  While some of these changes have been noticed by keen-eyed readers, I have not been able to find a single place documenting all these otherwise undocumented changes to the PHB.  As such, I hope the community here is able to document all these changes in a single Q&A, hopefully serving as a valuable resource to anyone looking for a proper accounting of the changes made in the November 2018 printing of the books - since the 2018 PHB errata fails to do a sufficient job of this.  As of the November 2018 core book updates, what changes were made in the latest printings of the PHB that aren't noted in the errata document?  Given the specific focus of the question (it's not an unrestricted list, and has clear correct answers), hopefully it should not be too broad to be answerable here.


I'm desperately trying to install ubuntu 12.10 64bit on my new Ultrabook. Its a Sony T13 with 8gb ram, 256gb ssd, i7, windows 8.   I have an extra partition, D: "UBUNTU" already created with about 30gb space using FAT32. Ubuntu is MD5 checked, on a previously working USB stick using UNetBootin. Grub loads fine When I ask to test out Ubuntu ("Try ubuntu without installing") it shows the purple loading screen for a bit then brings up this error in a busybox terminal:   initramfs - Unable to find a medium containing a live file system  Things I've tried that don't work:   Different versions of Linux (Fedora, Arch, SL, even gParted) Using USB2/3 - No difference Legacy or UEFI - different interface, but same error BIOS has no option for anything "ACHI" related   I have read through tons of other people having this problem and diligently tried all the above solutions, with no luck.

Error message:  (initramfs) unable to find a live medium containing a live file system   I got this error while trying to install Ubuntu 10.10 from a bootable USB stick on to Asus X64J series laptop. After getting this error the installation fails to start.  I have used the same USB stick on some other laptops and the installation started as usual. Any help will be appreciated.


In Excel 2010 I have several columns with data.  I insert a column, and type a formula in the top cell of that column.  I want to fill the formula into the remainder of the column, down to the same row as is filled for the other columns.  Once the selection is made, I could use Paste, or Ctrl + D to fill down.  My issue is with selecting row 1-N quickly (without the mouse).    Think of a sheet with 10k rows or more.  My current inadequate solutions are:   Use the mouse by scrolling and shift clicking on the last cell Use the arrow key while holding shift until reaching the last cell Use the page down key while holding shift until reaching the last cell Double click the formula cell handle to fill down (uses mouse) Ctrl + T to make it a table, then Ctrl + Space to select the data, then have to change it back from a table   Ctrl + Shift + Down works if the column has data in it, but if the column is empty it goes to the bottom of the sheet.

I'm looking for a keyboard shortcut that will duplicate the functionality available by double-clicking the "handle" in the bottom-right corner of a cell.  Is there something that can do this, without third-party software or creating custom macros?


I'm a newcomer to Ubuntu, and have just installed version 15.10 (64 bit) alongside Windows 10.  All seems to have gone well, but I can't boot Ubuntu from Grub.  I've checked the install from a live USB, and all appears ok (to my novice eyes).  Do I have to configure Grub in anyway, or have I inadvertantly installed the boot loader on an incorrrect partition?  I would be grateful for any advice, and apologise if this topic has already been covered previously.

I installed Ubuntu on a Dell XPS 13 laptop that had Windows 10 preinstalled on it. I installed it from a USB flash drive on a partition. When I boot my computer I can only boot into Windows 10 and Ubuntu is nowhere to be seen.  If I boot into my USB then I can see that Ubuntu is installed, but I can't get to it from the BIOS boot menu.


How would one prove the following? Let $F$ and $G$ be $\sigma$-algebras on $\Omega \neq \emptyset$. Then, $F \cup G$ is a $\sigma$-algebra iff $F \subset G$ or $G \subset F$.  One implication is obvious, but the other one.. I have no clue where to even start.  Thanks for your help.

I need help to demonstrate:  Let  $F,G$  two $\sigma$-algebra in $\Omega$, if $F\cup G$ is $\sigma$-algebra in $\Omega$, show $F\subset G$ or $G\subset F$.  Thanks

I have a simple 2-column layout with a footer that clears both the right and left div in my markup.  My problem is that I can't get the footer to stay at the bottom of the page in all browsers.  It works if the content pushes the footer down, but that's not always the case.


Please explain how to solve the problem. Here's what I have done. Prove by induction the following inequality $1 + \frac{1}{\sqrt{2}} + \frac{1}{\sqrt{3}} + ... +\frac{1}{\sqrt{n}} \leq 2\sqrt{n} - 1$  Base case. For n = 1, we have 1=1 Induction hypothesis. Assume for $n = k$ the inequality is true Inductive step. Prove for $n = k+1$  the inequality is true  $1 + \frac{1}{\sqrt{2}} + \frac{1}{\sqrt{3}} + ... +\frac{1}{\sqrt{n}} + \frac{1}{\sqrt{n+1}} \leq 2\sqrt{n+1} - 1$ Now I'm stuck. I think I may use the induction hypothesis but have no idea how to do it. By the way, all the solutions for similar problems that I've searched on the internet were either too complicated or not using induction.

Prove that for any positive integer $n$, $$ 2\sqrt{n+1}-2 \leq 1 + 1/\sqrt{2} + 1/\sqrt{3} + .... + 1/\sqrt{n}\leq 2\sqrt{n}-1 $$  the middle part can be expressed as a sum. of $1/\sqrt{x}$ from 1 to $n$, which leads to a $Hn^{0.5}$. Im not sure how that helps.  I tried differentiating both end functions and found they are both increasing.. But it doesn't seem to help much... help pls


As we all know the speed of light is the limit at which energy/matter can travel through our universe.   My question being: is there a similar limit for acceleration? Is there a limit to how quickly we can speed something up and if so why is this the case?  Short question, not sure what else I can elaborate on! Thanks in advance!

I'm thinking equivalence principle, possibilities of unbounded space-time curvature, quantum gravity.


I am facing issue with LWC, probably connected to the LockerService's Proxy objects.  My code  I am getting the list of custom objects defined in one of my Apex classes by calling Apex method from LWC JS file:  getSettingsForConfigType({configType: this.codeConfigType})             .then(settings => {                 //this.fieldList = settings;                 this.prepopulateConfig(settings);             })             .catch(error => {                 this.toastError(error.body.message);             })   The problem  The problem is I need to populate the settings object returned from Apex with additional field. This field is not defined in Apex (and I don't want it to be defined, it will be used only on LWC side). Whenever I try to add new field called fieldValue either with obj.fieldValue = ... or obj['fieldValue'] = ... syntax I get forrowing error:  TypeError: 'set' on proxy: trap returned falsish for property 'fieldValue'  Question  Is there any way to overcome this limitation or maybe I am missing something here?  P.S. Dirty workaround  settings = JSON.parse(JSON.stringify(settings));  However, it seems to be a bit ugly trick. That's why I posted the question :-)

How do the developers of games "hide" textures from editing. For example in game called Faster Than Light which is made in c++ using SDL. There is no directory with graphic files. How to "hide" textures?

I'm writing a game in C++ (with OpenGL) and am getting quite far into development. Currently I'm loading the data directly from different directories.  (E.G. I load textures from a /Data/Textures/...png)  This is fine, but not preferable. Ideally I would like to protect these assets without too much of a performance hit. I looked at other games that I own, both Indie and AAA and found that the majority of them archive the data. However, I am unable to access these archives with programs like Winrar Archiver which implies that they have some level of protection.  I'm not particularly knowledgeable in the field of encryption and data storage, so I may be overlooking something obvious but I would like to know how exactly I could achieve something similar.  (I am aware that competent individuals are able to use the GPU to gain access to the data but that's not preventable)


Consider the following c snippet:  int main(){     int *a = (int *)60;     int *b = (int *)40;       cout << a - b;      return 0; }   The following code give output as 5. My understanding is int *a defines a pointer to memory address of 60, so going by this logic the output should be 20. On outputting the values of a and b, it gives the hexadecimal representation of 60 (0x3c) and 40 (0x28); still the program prints 5.  Can somebody please explain the reason behind this?

Does anyone have any good articles or explanations (blogs, examples) for pointer arithmetic?  Figure the audience is a bunch of Java programmers learning C and C++.


Hotels in Europe seem to require (or at least want to see) your passport when you check in.  What happens if I cannot (or don't wish to) give this information? For example, if I am traveling without my passport, or just wish to limit the number of places which have access to my information?  Can I show a different form of identification instead? I'm not looking to be completely anonymous here, just understand what forms of ID are required to check in.

A few years ago I've visited a hotel in Munich and was pleasantly surprised to find there was no reception as such. To get the keys you had to call a 24/7 support line, where you received a code to a locked box outside the hotel door, which contained the key to your room. It wasn't required to show any IDs or fill out any forms. Upon checkout you simply placed the key back into the box, no questions asked.  I'm not a paranoid person nor am I hiding from the law, however I find the concept of traveling anonymously appealing. Is there a way to find out in advance if the hotel in question allows for fully anonymous check-in? And is there a website which allows you to find such lodging?  See also a  about airlines.


I leaked some water in my PS2 keyboard while it was connected. I turned my keyboard upside down to let the water out and didn't think much of it. Within 15 minutes my PC hard disk starts rattling and my monitor says 'no signal'.   When I tried to reboot (multi-boot Windows 7 and 10) the first time it said 'resuming Windows 7' but my PC became so slow and there was a huge delay on typing, if any keypress came through at all.  When I rebooted again it was stuck in a loop, rebooting as soon as it passed the BIOS checks (all HDDs found, no memory problems everything seemed fine).  When I enter the BIOS to check if there is anything wrong the BIOS is almost completely unresponsive. The BIOS screen is messed up as soon as I start pressing keys. It does not respond to most keypresses and instead starts replacing the text on the screen with blank space.  Is there any chance that this is caused by the water spilled on my keyboard? What is the suggested course of action?

I've heard that spilling liquid on the (wired) keyboard of a desktop computer can cause damage to the motherboard or other parts.  Is this possible, or will only the keyboard be damaged?  How does this apply to other input devices such as mice, assuming that they are wired?


Evaluate $$\int_0^1 \frac{\ln{\left(x+\sqrt{1-x^2}\right)}}{x} \; \mathrm{d}x$$ I tried $x=\sin{t}$ the symmetry with $t=\frac{\pi}{2}-t$ to get $$\int_0^{\frac{\pi}{2}} \frac{\ln{\left(\sin{t}+\cos{t}\right)}}{2\sin{t}\cos{t}} \; \mathrm{d}x=\int_0^{\frac{\pi}{2}} \frac{\ln{\left(\sin{t}+\cos{t}\right)}}{\sin{2t}} \; \mathrm{d}x$$ This looks much nicer I think but now what...? I considered $\sin{t}+\cos{t}=\sqrt{2} \sin{\left(x+\frac{\pi}{4}\right)}$ but that doesnt help.   Any hints or suggestions please. Integral equals about 0.61685028

By integration by parts and the substitution $x = \sin t$ we can easily calculate the integral $\int_{0}^{1} \ln (x+ \sqrt{1-x^2})dx$ which equals to $\sqrt{2} \ln (\sqrt{2} +1) -1.$ I’ve tried to use the same substitution $x = \sin t$ to calculate the integral $ \int_{0}^{1} \frac {\ln (x+ \sqrt{1-x^2})}{x}dx,$ which becomes $$ \int_{0}^{\frac {\pi}{2}} \frac {\ln \sin (t+ \frac {\pi}{4})}{\sin t}dt$$ It seems difficult to solve the particular integral. Any help?


I am using Illustrator CS3 and trying to export my illustration. Problem is, I wanted to only export the illustration, no the background canvas area, how I can achieve that?  Thanks.

The title says it all, I want to know what the simplest way to export the selected objects.  In Inkscape, there is a menu option called export selected which does just this.    The aforementioned option lets you export the selection as a composite image or as a batch of individual images.  Both would be nice, but in this scenario I want to export the selected objects as a single image.  I can already create a new document, and paste in the selected items.  I am looking for a way that is easier than this.  How can I save / output / export only the objects I currently have selected, to an image file, in Adobe Illustrator CS5?


I know there exists a term for the to–too–two situation where the words are pronounced the same but spelled differently.    Is there a term for the situation of unionized /ˈjuːnɪənɑɪzd/ and un-ionized (sometimes spelled unionized) /ʌnˈaɪənaɪzd/ where the words are pronounced differently but spelled the same?    Also, since I can't find it, what is the term for the to–too–two dilemma as well?

What do you call words with identical spelling but different meaning and different pronunciation? A couple examples are bass and resume.


I have multiple domain names, currently all of them are on a single SSL certificate through Lets Encrypt. However I would like to break them off and get individual certificates for each domain. The problem I'm running into, and what I'm hoping to accomplish is this: I have several subdomains that are being reverse proxied. IE sd1., sd2., sd3.*, etc. At the moment this works fine while having a single certificate for all domains. Regardless if someone accesses sd1.domain1.com or sd1.domain3.com it uses the single certificate and all is well. I'm trying to find out if it's possible / the proper way to have the certificate be handled by the domain requested without having to create server blocks for each subdomain / domain combination. I'd like to keep sd1.* as a server block for the reverse proxy but if sd1.domain1.com is accessed have it provide the domain1 certificate and if sd1.domain2.com is accessed have it provide the certificate for domain2. Is it possible to have NGINX provide the certificate based on the host/URI that is requested rather than only by server block?

How I can use a variable name in file path ?  ssl_certificate /home/ec2-user/.certificados/$server_name.crt; ssl_certificate_key /home/ec2-user/.certificados/$server_name.key;


Under current particle theory, the four fundamental forces use a force-carrying particle. The particle for electromagnetism is the photon.  By definition a black hole is a mass from which light can not escape, so how does the photon get out of the black hole to carry the charge force?

By the "No Hair Theorem", three quantities "define" a black hole; Mass, Angular Momentum, and Charge. The first is easy enough to determine, look at the radius of the event horizon and you can use the Schwarzschild formula to compute the mass. Angular Momentum can be found using the cool little ergosphere Penrose "discovered". However, I don't know how to determine the charge of the black hole.   How can an electromagnetic field escape the event horizon of a Reissner-Nordström black hole? Is there any experiment we could theoretically do to a black hole to determine its charge?


Edit: This is not a duplicate of  because that question only seems to talk about adding an image texture, not combining an image texture with additional shader effects.  Original question:  I want to make the paper you'd find in a fortune cookie. To create the shape, I extruded a bezier curve and added a Solidify modifier to it.  For the material, I tried this:   Made an image texture and added text in Photoshop Made a Principled BSDF shader with subsurface scattering Used an Add Shader to combine the other two shaders   However, the text of the image gets faded:    How would I put opaque text on translucent paper?

I am creating a model of a glass and I would like to put a drawing on it (a png picture).  I know how to do it using Blender Render, but not with Cycles Render. Help :)


How can I see how many posts I have edited on Stack Overflow? I'm trying to get 80 edits for that badge but I can't see anywhere how many I've already got.

I've found  many queries to check edit counts, and I get different results for each one. Which one is the most accurate and up-to-date query? Or is there any way to see the edit count in stats?


This might be a terrible idea, but is it possible to have non-installed packages automatically installed? That is, instead of seeing this:  $ git clone ... The program 'git' is currently not installed. To run 'git' please ask your administrator to install the package 'git'   Seeing this instead:  $ git clone ... Installing package 'git' ...

For years I have been trying to track down a film that I saw a clip of on an old BBC show called Screen Test.  They introduced the film as "having used the most scrap from scrap yards than any other film."  It was either an Australian or a New Zealand film. Post apocalyptic like Mad Max. In-fact for years I thought Mad Max would be the film, but it wasn't.  They showed one scene from the film which the contestants answered questions on.     A six wheel truck drives up to the camera. It looks like a Mad Max truck. There are at least two people in the truck, a man sits close to us with a woman next to him. He looks through binoculars (sci-fi bins). He sees a long trailer thing on rails and it has sails. Then this land ship is attacked by bandits on motorbikes or something. The sails fall and people run about panicking. Then we cut back to the truck and it drives away.   The film is not Battletruck or Damnation Alley. The truck I think had six wheels, but I could be wrong. Not evenly spaced wheels, with the second wheels set back. A gun slung at the back, like a chain gun. It was futuristic like and pointy like a Lambo, not a square truck. In black or dark grey.  Like this but with another set of wheels at the back and painted dark:    It probably wasn't a very good film and has dropped below the radar of obscurity. Anyone who could help ID this film for me would be greatly appreciated.  You can see how obsessed I am as still making models of it in Lego:    Here is a bad drawing of what I remember:

I am trying to identify a sci-fi movie from the 80's or 90's, with the following parameters:  Setting:    Scenes of a red desert planet   Culture:    Either people roam fairly solo and try to acquire resources to survive, or you live in a weird society where if a stranger is captured he needs to play in a game of fight to the death.  Mobility:      One foil character has a giant battle-bot-looking tank as his form of transportation through the desert. Protagonist has a car that has a plastic half bubble on top to look out from.   Robot:      The protagonist runs around in the beginning of the film with a female robot/android whose face is melted off after it has acid touch its face.(This scene happens next to the protagonist's rover)  Love interest:      Somehow protagonist comes across female protagonist in desert. She smells really bad and is hungry. They sleep outside, and he tells her to sleep away from him. He uses a thermal blanket(the first I ever saw in my life). She wakes up next to him, smelling horrible. He bathes her in some water hole they find(as if water were not scarce and they could just waste water.)   Pupa monsters:      Scene where they are in a building and they are trying to get out. They come across a room that is white, in which multiple giant, white, snot, pupa are hanging securely from the ceiling. Through curiosity, they disturb them, and now they have to get out of that room fast.  Boss Antagonist:      Pervert bionic man, that is actually attached to a giant robotic arm, as only form of movement. He is in black and has a pale bald head as his most human looking part.


Does asymptotic normality imply consistency?   Update: Asymptotic normality implies consistency, as proven in this quesiton:

In a statistics book i'm reading, it is postulated that asymptotic normality of an estimator implies consistency. That is $$ \hat{\theta}_n \stackrel{as}{\sim} \mathcal{N}(\theta_0, \frac{1}{n}\sigma(\theta_0)) \Rightarrow P_{\theta_0}(|\hat{\theta}_n - \theta_0|>\epsilon ) \to 0 $$ when $n\to\infty$, for all $\theta_0 \in \Theta$ and $\epsilon>0$.  I am trying to prove this, but i can't seem to get a breakthrough.   If anyone could shed some light on how this is proven, i would be very grateful.


I dread clicking on the inbox icon because clicking it means that all messages are no longer "unread" and the notification number (usually color red) will go away. It means we must wait until we am ready and expect to have the time to go over all notifications (which may not be the case, especially if we are interrupted to go do something else). Sometimes, we just don't want to look at all new messages at once, and we want to keep them unread so we know what we need to get back to later. The useful highlight on each message fades away when we click on the inbox icon. After navigating, it is no longer possible to tell which topics we have already visited because the highlights are gone. It would be great if inbox items were left unread (and still highlighted) until clicked on, and the top bar numerical indicator left with a number of how many unread are left, so that we have a clear way of knowing which items we need to get back to instead of having to check all of them to regain context of what we're doing. The following is what I see. I had many unread items, but I can not tell which ones I already visited and which ones I still have to read, which makes things more difficult. All of the following items except for two are unread. Can you tell which ones are unread?

Currently, when receiving notifications in the inbox, you get a number in the top bar on the inbox button. But when you open the inbox that number is gone and everything is marked as read. I don't think this is good behaviour.  I would suggest that only the messages that were clicked are marked as read and the number simply decrements. This would make it easier to follow-up on them. Also there can be buttons for marking individual messages as read, marking them as unread too, and a big button to "mark all as read".  A humble attempt at propagating my suggestion into a design:        I had to fake one of my notifications being unread and sorry, it's badly done. Notice the "mark all as read" conveniently placed in the top right. Notice to the bottom left of each notification the individual mark as read button, in the shape of a bold checkmark for "unread" and a lighter one for "read". This could also be an o for read and a ● for unread or anything else that the designers see fit.  Question history about this here   was already asked here but this was declined simply because it asked for a setting and SO doesn't do preferences. I'm asking to modify the default behaviour.  Then there's  but the so-called duplicate is not a duplicate at all. Also this was before the entire top bar was re-done and it was still the Stack Exchange MultiCollider SuperDropdown thing.

Microsoft is giving Windows 10 away for free to Windows 7/8/8.1 users. If one reserves Windows 10 with the new notification in the tray area, what will happen to their Windows 7/8/8.1 license?  Are you really getting Windows 10 for free, as in you upgrade from 7/8/8.1 but you still own the previous version of Windows and Windows 10, or are you really trading your old Windows license for a new one?  Basically, after upgrading to Windows 10 for free from Windows 7, will I still own Windows 7? (Will the product key for 7 still work?)

Microsoft is offering "Microsoft Windows 8 Professional Upgrade" at a discounted price compared to the OEM version. However it states:     If you currently have a personal computer running Windows 7, Windows XP or Windows Vista then you can upgrade to Windows 8 Pro (Professional).   My question is what happens to the Windows 7 key that I use to upgrade? Will it become the Windows 8 key or will it generate a new Windows 8 key?  Basically if I upgrade using my Windows 7 key from my laptop for my desktop will I be able to continue using the laptop on Windows 7 while concurrently using Windows 8 upgrade on my Desktop?


Suppose you had the prime factorization of $x = \prod_{k=1}^m p_k$. Are there any algorithms for deciding the prime factorization of $x + 1$? Are their prime factorizations related in any way at all?  EDIT: It's known that $x$ and $x + 1$ are coprime. That means that you get some amount of information about the prime factors of $x + 1$. Can the information about prime factors of $x$ be used to figure out the prime factors of $x + 1$ faster than just "prime sieve" + "filter out the factors of $x$"?

Are there any theorems that give us any information about the prime factorization of some integer $n+1$, if we already know the factorization of $n$?  Recalling Euclid's famous proof for the infinity of the set of prime numbers, I guess we know that if $n = p_1 p_2 p_3$, then $n+1$ cannot have $p_1$, $p_2$, or $p_3$ as factors. But is there any way we could use the information about $n$'s factorization to determine something more precise about the factorization of $n+1$?


For an integer number $a$  $$x^a=\{(x)(x)(x)...(x)\} (a\,times)$$  $$x^{\frac{1}{b}}=n\rightarrow\;\{(n)(n)(n)...(n)\}(b\,times)=x$$  For rational number $m=\frac{a}{b}$  $$x^m=x^\frac{a}{b}=(x^a)^\frac{1}{b}$$  And can be though of as a combination of the situations before   What about   $$x^e$$  How would one calculate or picture this from more basic operations?

The way that I was taught it in 8th grade algebra, a number raised to a fractional exponent, i.e. $a^\frac x y$ is equivalent to the denominatorth root of the number raised to the numerator, i.e. $\sqrt[y]{a^x}$. So what happens when you raise a number to an irrational number? Obviously it is not so simple to break it down like above. Does an irrational exponent still have a well formed meaning?  The only example that comes to mind is Euler's identity, but that seems likes a pretty exceptional case. What about in general?


It has been stated several times here and probably elsewhere that the first population III stars were  to undergo H-to-He fusion via the CNO cycle as there was  at the point of the first stars forming, and they were stuck with the pp chain.   What I have a question about though is that it has been shown that  in primordial nucleosynthesis. This means there was around 10^65 carbon-12 nuclei already in existence which seems to indicate there would definitely be a non-zero probability of the CNO cycle being able to function in the earliest stars. It may have not been quite as dominant as it is today in high mass stars but it seems like it would have had an impact right from the beginning.    So how come it is still stated that the CNO cycle couldn't have happened in the earliest stars when it seems that the material needed for it was already present (granted not nearly in as high amount as it is today)?

CNO cycle requires the presence of carbon, nitrogen and oxygen to undergo hydrogen fusion. Does this mean that for first generation stars, no matter how big they are, can't undergo hydrogen fusion by CNO cycle because there is no carbon, nitrogen and oxygen present?   I can't seem to find any website which mentions this. All they say is if a star is large enough, it will undergo hydrogen fusion via CNO cycle, they don't specifically mention it having to be a second generation star.


With your help, I have figured out how to replace + or - in math mode with a custom macro:   Now, I need to extend this by replacing only binary - (e.g. x-y or x - y), but not unary - (e.g. x + -x or -z). Thus, I need to, in some sense, test to see whether a - is unary, or binary, which is what TeX does anyway when figuring out spacing around -.   So how does TeX do it?

I've occasionally seen a negative (when a number is simply negative, not a subtraction), typeset as negative sign that's slightly skinnier and above the centre line of text. Is this proper notation for mathematics and how would one go about typesetting this in LaTeX?   Edit  I believe that calculators were what happened to give me this idea, couldn't find it in any of my math books. Thank you all for the help, it's much appreciated.     Thank you 'Antal S-Z' for the photo link.  However, the question remains, how exactly would I typeset this?


Why is it, when I update, save and publish a landing page, that the changes are not immediately available when you request the page?   The changes to a landing page seem to go live with 5 minutes interval, despite the option at time of publishing a landing page saying 'publish immediately'.  Am I having too high expectations?

Simple question: how do you guys develop (write) a landing page and test it? Publishing and waiting for updating url and refreshing?  Isn't that a little bit "horrible"?  Any idea of developing and testing with cloudpages?  How can I see errors in my ampscript code when my landing url throws a 500 error?  Thank you!


In C# an object can be created based on knowledge of the desired type like this (among a few other ways)  public T GetInstance<T>(string type) {     return (T)Activator.CreateInstance(Type.GetType(type)); }   Is there an equivalent way of doing this in native c++?  I have a base class and a derived class. I wish to construct the proper object based on stored data. I have control over what this stored data is, but I need to know what information needs to be stored to identify the type and then how to use that data to later call a constructor.   I'm essentially looking for the c++ answer to this question:

I have a file: Base.h  class Base; class DerivedA : public Base; class DerivedB : public Base;  /*etc...*/   and another file: BaseFactory.h  #include "Base.h"  class BaseFactory { public:   BaseFactory(const string &sClassName){msClassName = sClassName;};    Base * Create()   {     if(msClassName == "DerivedA")     {       return new DerivedA();     }     else if(msClassName == "DerivedB")     {       return new DerivedB();     }     else if(/*etc...*/)     {       /*etc...*/     }   }; private:   string msClassName; };  /*etc.*/   Is there a way to somehow convert this string to an actual type (class), so that BaseFactory wouldn't have to know all the possible Derived classes, and have if() for each one of them? Can I produce a class from this string?   I think this can be done in C# through Reflection. Is there something similar in C++?


So... me and my friend have been arguing ever since Avengers: Age of Ultron was released.  He thinks that Vision is literally just Jarvis in a new body. But I disagree. I think that Vision is an entirely new entity. ...let me walk through this  So Ultron tries to make a perfect synthetic body for himself and uploads a good bit of himself into the body... then Tony and Bruce get ahold of it and try to upload Jarvis into it (they start to but it's ruined by Quicksilver). Then Thor (after seeing  visions of the future and the world being destroyed by the mind stone) brings Vision to life with an electric hammer bash.  The Vision then wakes up and is confused about where he is. After a brief fight scene he is changing his appearance...and talking.  From the :     Steve Rogers: Why does your "vision" sound like JARVIS?   Tony Stark: We... we reconfigured JARVIS' matrix to create something new.   Steve Rogers: I think I've had my fill of new.   Vision: You think I'm a child of Ultron?   Steve Rogers: You're not?   Vision: I'm not Ultron. I'm not JARVIS. I am... I am.     So... in that last line Vision stated that he is NOT Jarvis. Yet my friend still states that Jarvis is the Vision. And I have argued back as well as I can but he won't budge. But I feel that fact is...that Vision (although he has some ofJarvis that he was made up of) is an new entity and is not "controlled" by Jarvis (like the way Jarvis can control the Iron Man suits).  This is a very raging argument and im slowly being beat down by a lot of nieve people agreeing with him. And I would appreciate a lot of feedback on the matter below. So is Jarvis the Vision?

Towards the end of Avengers: Age of Ultron JARVIS uploads himself into a lifeless Virbranium android. This process creates Vision. Then before the final battle we see Tony Stark uploading a program called FRIDAY into his suit. During the battle we hear a feminine voice in The Iron Man suit instead of JARVIS'. So did JARVIS cease to exist after uploading himself into Vision? If so did JARVIS know that this would happen, or was it because of the Mindstone?


Question is to prove that :  $A_n$ contains an isomorphic  copy of $S_{n-2}$  I have no idea from where to start.  I do not even believe this can be true (expect for cardinality conditions).  But as this is an exercise.it has to be true.   please provide some hints/suggestions to attack this problem.  Thank you :)

I'm working through Rotman (1994). It's the 2nd chapter where my curiosity lead me to a question that is not from the book. Here's the problem that inspired the question:      2.8. Imbed $S_n$ as a subgroup of $A_{n+2}$, but show, for $n\ge2$, that $S_n$ cannot be imbedded in $A_{n+1}.$    Since the alternate subgroup has the property of even parity, I thought that a little investigation of parity for the second and third symmetric groups was in order. So I constructed a table for each of them, grouped by even and odd number of disjoint products.   I'll forego writing the actual table and simply provide the answers. In symmetric groups with an even idegree, two even permutations come together under composition to produce an even permutation. Two odds also make an even. Two different parities produce odd elements.   When the symmetric group has an odd degree, e.g. $S_3$, two odds make an odd, two evens make an odd, and two different parities make an even element. Exactly the opposite results from the symmetric groups with even index.   Two questions: is this enough to prove the $A_{n+1}$ case? And can this be generalized modulo 2 e.g. $A_{2n+1}$?


Since I've made small upgrades from upgrade manager, I started getting this unusual starting process (line of codes).    After that, my OS is fully loaded, but I want to make this as need.

Is there a way to easily turn on/off showing the boot messages (loading the services) when Ubuntu starts? Is it something in Grub2?  I am running 10.04.


Disclaimer: I know there's already been some discussion on this topic, but I'm going to ask the question anyway because I've never played the game before, and thus, have yet to use my copy of Power Grid in the context of actually playing the game.   What are some general tips for people who have never played before to get started and have an actual idea of what they're doing in Power Grid? Also, what are some tips for explaining the game to people who have also never played the game before?  P.S. Sorry if this question seems like it's been asked before (and thus, horribly redundant), and altogether a dumb question

Tonight I'll be playing Power Grid for the second time with my game group. It's the second time for all of us.   What key strategy or tactic should I focus on to give me the best chance of winning?


I am learning about the Inner Class in Java, but i write this code, when i compile it, i got this error: Error:(84, 23) java: non-static variable this cannot be referenced from a static context.      public class Main {      class Outer {         private String string;          Outer(String s) {             this.string = s;         }          public Inner inner() {             return new Inner();         }          class Inner {             @Override             public String toString() {                 return string;             }         }     }      public static void main(String[] args) {         Outer outer = new Outer("yang");       //  System.out.println(outer.inner().toString());     } }   I have update the Inner Class to this, and it works.  public class Main {      static class Outer {         private String string;          Outer(String s) {             this.string = s;         }          public Inner inner() {             return new Inner();         }          class Inner {             @Override             public String toString() {                 return string;             }         }     }     public Outer outer(String s){         return new Outer(s);     }     public static void main(String[] args) {       //  Main main = new Main();         Outer outer = new Outer("YANG");         System.out.println(outer.inner().toString());     } }

What is the main difference between an inner class and a static nested class in Java? Does design / implementation play a role in choosing one of these?


I'm trying to make the stairs railing poles with an Array following a Curve. Is there a way to control which way the Poles are facing? I want to point them all straight down (vertically).

I'm trying to create a row of street lights, both the lamp pole and a spot light. Since i can't simply join these two and use an array + curve modifier to set this up (using an array modifier + a curve modifier always deforms the mesh) so i came to the conclusion that working with collections and instances would be my best bet.   To get to my current result i parented the spot to the lamp mesh. Then i parented those two objects to a plane. after that i parented the plane (and so also the lamp mesh and the spot) to a curve that i converted to a mesh. I then activated Instancing for the curve with verts which resulted in something like this:     As you can see the lamps all face the same direction, while i want them to be rotated inwards. There's an option for 'aligning the objects to vertex normal'     but enabling this exposes a multitude of problems:   Problem 1: it turns out there's two instances of every object. (i have no idea why) Problem 2: the street light meshes get deformed.      Problem 3: the actual lights all face toward the same place     (I drew over the lamp directions with blue arrows for visibility)  If anyone knows how i can get this to work i'd really appreciate it, but other techniques are welcome too.


Me and my friends were playing and I chose to destroy his creature but in response he used its ability to sacrifice it but in response I chose to use another instant of destroy target creature so my question is can I do that or no since the stack is involved and it’s not sacrificed to cast it since it’s already in play  So is it Scenario 1: I use “” to target his “” so he sacrifices it in response to deal 3 damage to my “” but in response to that I play another “Murder” that targets “Aerie Ouphes” again can I do that since by the stack my second “Murder” would go off first before his ability to sacrifice it  Also my friend thinks he can do Scenario 2: I use “Murder” to target his “Aerie Ouphes” so he sacrifices it in response to deal 3 damage to my “Vampire Nighthawk” but in response to that I play another “Murder” that targets “Aerie Ouphes” again but in response to my second “Murder” use “Aerie Ouphes” ability again choosing to sacrifice it and deal the damage to “Vampire Nighthawk” a second time but with the same card ability twice in a stack  I was thinking wouldn’t it go on the stack as  1: Murder targeting Aerie Ouphes 2: Aerie Ouphes ability to sacrifice it and deal damage to my Vampire Nighthawk 3: second Murder targeting Aerie Ouphes  Then the stack would go through with the last thing activated in the chain first

This is a broad question so for simplicity I will use  and .  Scenario 1: Common exchange- creating a baseline.   Player A uses Naturalize on Seal of Fire  Player B Sacrifices SoF in response. SoF is highest on the stack and goes off first.  This leaves Naturalize without a valid target.   Scenario 2: Complicated exchange- Is this legal?   Player B Sacrifices SoF. In response Player A targets it with Naturalize. SoF is on the stack and it's ability has not resolved. Player B (as above) sacrifices SoF in response to the Naturalize.    Can Seal of Fire be placed back on the stack by re-activating its ability, potentially with a new target?


I read a general principal of graph theory which says "A graph that can be traversed without lifting the pencil from the paper , while tracing each edge exactly once, can have not more than 2 odd vertices." Can I have any proof of it? I am new to graph theory

Is the below brief explanation correct and complete (at least in context)? Can it be improved/simplified without getting technical? I am especially concerned about the last sentence: Is that reasoning absolutely clear to a layman?            The problem can be viewed as drawing the above graph without lifting your hand and without retracing a line. Observe that each dot is connected by three lines. Also observe that you have to draw a line to arrive at a dot, and you have to draw a line to leave that dot. Because each dot is connected by three lines, each must be visited twice. But it is impossible to visit each dot twice (even number of times) and end up with each dot connected with three lines (odd number of times).


Problem: I created an input field with type text, but when page loads it is auto filled with username saved (saved for this website login page)in browsers form data. i want to show it clean when page load.  <input type="text" class="form-control search-field" placeholder="Search Item"  ng-model="vm.applyCategFoodSearch" autocomplete="off"  name="txtFieldForSearchItems">   i am unable to find solution, autocomplete='off' was suggested by many other sources, but issue not fixed. if it can be handled using html,jquery,javascript,angularjs. it will be good. I also reset the values in controller    vm.applyCategFoodSearch='';   timeout also tried but not working        $timeout( function(){          vm.applyCategFoodSearch='';     }, 5000 );   if i set time out to 10seconds, it will work, but its not the solution. i am sending ajax call for food categories,when it returns, this timeout code will run with 10second delay.it will work. other than 10second delay.it will not work.

How do you disable autocomplete in the major browsers for a specific input (or form field)?


Not sure how I report/flag a "hot network question" or even if I have the reputation to.  However, the "" question is on the "Hot Network Questions" sidebar.  However, the discussion of animal abuse in the question is somewhat macabre.  Does this qualify to be removed from Hot Network Questions?  I can't remember how to report items in the sidebar.

Part of my daily routine is to go to stackexchange.com and see the hot questions. Today this hot question was up:    The question itself seemed like it might be a problem but my curiosity got the better of me, and I was not expecting to see quite so much graphic detail about the nature of the abuse -- to the extent that it ended up giving me a panic attack.  I feel like this question (especially in detail) is likely to cause a lot of emotional grief for a lot of people, and it would be beneficial if it could be flagged with a content warning and, ideally, if questions like those would not show up on the "hot questions" list.  The question itself is legitimate and I am glad the user asked the question -- and the answers they received are, also, quite beneficial. But it certainly isn't the sort of thing I was hoping to be confronted with, especially as a "hot question."  Thus, what I am proposing:   Have the ability for the community to flag such comments with a content warning Prevent such posts from appearing on the "hot network questions" display and sidebars.   Edit: It appears that the question has since been deleted. I have mixed feelings about this (the answers which were given would have been very educational for the person asking). Regardless, I still feel like a content-warning mechanism would be helpful; sometimes there are questions that are important and valid but which are also troublesome for some people to see.  The use of CW-based partial-hiding is well-established in communities such as Mastodon, where people can put things behind a structured spoiler/CW tag that indicates what lies behind it.


The inhibitor chip ensures that Clone Troopers of the GAR will unquestioningly execute Order 66 when it is given, denying them free will in that crucial moment. How does it do it though? More specifically, does the chip execute its function via temporary mind control or a permanent change to their brains?  The implications are that, for the former, the clones will eventually regain full control of themselves, thereafter realising what they have done and will most probably regret their actions since, in such a case, the Jedi's trust in their loyalty are not unfounded in a sense. For the latter, I feel that there may be various ways it is achieved. The chip may either permanently override the clone's brain, taking control for life, or it may reconfigure the clone's brain altogether, such that while the clone is still in full control of himself, he is literally no longer the same person he was prior to the Order.  As such, how the inhibitor chip executes its intended functionality affects the nature of the chip's design and how it is implemented.

. When activated, troopers would immediately perceive Jedi as a threat and kill them.  Since Anakin was a Jedi until around the time of the Order, how did the troopers know not to kill Anakin?


From my understanding (and research) focal length affects how a face will end up looking on a photograph.  Here's an example of focal length distortion on a full-frame sensor:    My question is: will a photo taken with a 28mm focal length on an APS-C sensor look identical to a photo taken with a 40mm (28mm equivalent on a full frame sensor) on a full frame sensor? or will the levels of distortion remain the same as with a 28mm - full-frame sensor combo?

I see many posts on both this forum and elsewhere the discuss the use of a wide angle on a crop sensor.  For example, they discuss how at 14mm lens is 14mm on a 35mm film or full frame, but with a 1.6x crop sensor it is an effective 28mm.  My question is, is a 14mm on a crop sensor the same image as a 28mm on a full frame.  Or does "effective" include some other conotation.  I read that a 14mm can create distortion on a full frame and some vignette, so people seem to say using it on a crop takes out some of those edge problems. My confusion is how the lens is actually taking in the extra image.  Reading kenrockwells blog I learned that wide angle keeps lines straight, while fish eye actually skews the lines.    So with this as my understanding, I am still a bit confused how a lens that is curved in order to get a greater angle of view, will be the same as a cropped version of a less curved lens.  Or does "effective" only refer to the objects to the sides but not to the distortion of the image.  Or, if it is different, is it so small that for photography it does not matter?  A technically description would be welcome as long as a basic understanding of the situation.  Thanks!  Edit: To be more clear after the comments,  I am specifically talking about the end resulting 2d projection from 3d space.  I have read both those previous answers.  the first one is closer to what I am talking about.  However, it is still confusing for me.  I have experience with 3d modeling and projection matricies, which might be confusing me with this.  But for example, i dont understand the images having a 50 mm lens being drawn Starting from the sensor, so it shows a different fov for crop and full frame . If the lens is the same, it takes the same amount of information from the world, which makes a ray from a certain degree off the last lens projected into a smaller space, there is no projection from the sensor, so drawing the line from the sensor doesnt make sense to me.  The distance of the sensor to the rear of the lens must have some impact on the light projected but is not represented in the images.  Further, again from that first answer it says cropping is the same as zoom, but from what i understand from how perspective works, it is different, since a wide angle will project lines differently than a small fov to the same size, so cropping the center of a wide angle and zooming into something is very different.  This is easily recreated in an opengl application with varying fov projection matrix, i imagine in painting class people learn this as well.  A fisheye would be a good example, since if cropping was the same as zooming, a fish eye lens would keep the center exactly like a normal lens and then a gradient weighted towards the outside would rapidly create a warped perspective, but from what I see, it is even.  To me those images just look like its comparing cropped with full frame in regards to orthogonal projections.


I need to disable docker services when Ubuntu 18.04 starts.  I tried with:  update-rc.d -f <service> remove   but this doesn't work.

I was trying to experiment with docker, Ubuntu 14.04, 64-bit. I managed to run an image, and I gave it the path on one of my removable drives, /media/Drive1.  Now, whenever I reboot, I see there is a /media/Drive1 with only a docker directory inside it, and the actual drive which should be Drive1 ends up mounted on /media/Drive11, and this happens every reboot - even when I unmount these drives, and do a sudo rm -rfv /media/Drive1 before rebooting!  So something probably creates /media/Drive1 before it is fully mounted, and I guess that something is docker, because when I boot, I have:  $ ps axf | grep docker  2085 ?        Ssl    0:00 /usr/bin/docker -d   So, how can I disable the docker autostart, so it doesn't interfere with the mounting of external USB drives at boot?


I must admit I'm on shaking ground here, because I haven't seen it, I've just heard this movie menioned once (about five years ago?) - or at least I think it was a movie, but since I think it's based on a book, it may be the book I've heared mentioned.  In retrospect, it may have been early talks about "The Hunger Games" - but I think not.  Some (young?) teens have been abudcted and placed on an island (or somewhere else remote and isolated).  (I assume) Only one of them will be allowed to leave, so they'll have to fight and kill eachoter.  To prevent them from co-operating - or hatching a plan to escape - they've all been collared with something aikin to shock-collars that will shock them (and possibly kill them) if they spend too much time in proximity to eachother.  I believe it's somewhat "Saw"-like...

This is something I heard mentioned in passing several (around five?) years ago, so I haven't read the book, nor have I watched the movie.  I think I heard about the movie, but I believe it's based on a book.  It's really more horror than sci-fi/fantasy, but I guess it could qualify for some sci-fi/fantasy sub-genres...  In retrospect, I've thought that what I remember is a lot like "The Hunger Games" and that I may have heard early talks about the film adaptation, but I don't really think so...

I am seeing a problem on my Drupal 7 site relating to image styles.   A bit of background - This site was built by migrating the content and config from a previous site, using the Migrate and Features modules, after the previous site fell victim to Drupalgeddon. The new site seems now to be 99% working. (After fixing a lot of stuff that wasn't properly copied across by Migrate and Features - whether that was due to my inexperience in using these modules, or shortcomings of the modules, I don't know.)  One thing that isn't working is uploading image files into fields of type Image.  The Image gets uploaded successfully and is accessible from /sites/default/files/. But no files are being created in any of the subfolders below /sites/default/files/styles. So the thumbnails don't display.  I've tried a lot of the advice I've found while Googling - the UNIX file permissions seem to be OK, the Drupal permissions seem to be correct, I can't seen anything wrong in the .htaccess files, but perhaps someone out there can give me better guidance on what to look for here.

I'm using the Insert module to allow users to insert images with a specific image style into a page. After upgrading to Drupal 7.20, the images are not stored in the files/styles folders, and the image url returns a 403 (access denied) error. I checked the folder permissions, and they are all set to 777.


In the season 8 episode, we saw the following symbol  His victims in this episode were the residents of Last Hearth—the seat of House Umber, a Northern ally of House Stark. None of them were left in the Northern fortress except for the young Lord Ned Umber, dead and nailed to the wall amidst a slew of severed limbs in a spiral pattern. Tormund and their crew find the haunting symbol when they arrive at Last Hearth. "It's a message from the Night King," Beric notes of the bloody formation. But what is the Night King saying? We have seen the same kind of symbol in Season 1, Episode 1. So what is the meaning behind those symbols?

In Game of Thrones S8E1,        Ned Umber is found pinned to a wall by the Night King with a symbolic message, which looks like tentacles coming out of the body of Ned.   Is there some meaning to that symbolic message? If yes, then what is that?


To remove all emails for all users of a Linux machine, I run:  find /var/spool/mail/ -regextype sed -regex "^.*[^/]$" -exec :> {} \;   ... however I received the following error message(s):  find: ‘:’: No such file or directory find: ‘:’: No such file or directory find: ‘:’: No such file or directory   What is wrong?

In bash:  $ type : : is a shell builtin $ type true true is a shell builtin   Looks like they are the same, but they don't give the same system trace:  $ strace : strace: :: command not found $ strace true execve("/bin/true", ["true"], [/* 82 vars */]) = 0 [snip] exit_group(0)                           = ?   I tried diffing strace bash -c : 2>:.txt and strace bash -c true 2>true.txt, but couldn't find any differences between them except for the memory locations.  In dash:  $ type : : is a special shell builtin $ type true true is a shell builtin   OK, so they are not the same. help : and help true aren't very useful, and they return the same in bash and dash. Is there any practical difference at all between them, except that : saves three bytes and makes scripts less readable?


I have an Android device that supports both 2.4 and 5Ghz bands. Also my WiFi router is dual band. I know that 5GHz band supports higher speeds but the difference isn't significant for my connection speed (50 Mbps). Does connecting to the 5GHz drain more battery than 2.4 GHz?

Are there any difference for phone battery life when connected to 5 GHz access points vs connecting to the same at 2.4 GHz?


I've been trying to obtain some turtle eggs (got silk touch on my pickaxe) to get them at my home base for my home beach, however, I keep feeding the turtles sea grass, one does get fatter and I get the XP but whenever they swim off and I follow them (and I've followed several for over an hour) they do nothing but swim aimlessly, and sometimes in circles.. it's not an area I've been before so I haven't destroyed anything and they're free to go as they please.. can someone tell me what I'm doing wrong? It's super frustrating~

I recently made a turtle breeding farm in Minecraft survival mode and when ever I bred the pair of turtles all I got was experience points and that’s it, they did not lay eggs and yes the farm was next to the ocean and there was sand for the turtles to lay their eggs.


What SSL certificate should I buy to get my domain work? I use nginx web server and want that all users requests go to https.    http://example.com -> https://example.com http://www.example.com -> https://example.com https://example.com -> https://example.com https://www.example.com -> https://example.com   Do I have to buy 2 certificates for both domains example.com and www.example.com? Or may I buy only one certificate with subdomain support? What does SAN mean in SSL-certificates and how can it help me?    What nginx config do I need to get desire redirection?  Thanks.

I have purchased an SSL certificate and I should be able to configure IIS 7 to use that certificate for both  and   I have looked online but didn't find a solution so far. Is this possible to do? According to the company that issues SSL, a single SSL can be used in both cases.  Thank you


Currently, Ctrl + ↑ / ↓ has the same effect as ↑ / ↓, it edits messages.  It would be nice, if Ctrl + ↑ / ↓ could be changed to quick-respond to other messages instead. This avoids having to switch from keyboard to mouse everytime one wants to respond to a specific message.

Yes, I know there's a script for that. But I think it's useful enough to be inserted into the live chat for everyone.  The following keyboard shortcuts are incredibly useful:   CTRLUp and CTRLDown - For replying to messages (each Ctrl+Arrow should change the :[message ID] in the chat input. CTRLSpace - For retrying a failed message, or ESC to cancel it. There should also be a keyboard shortcut to edit a failed message as per the newest functionality (Maybe the Down key?)   Using a chat with only the keyboard is very useful, it will be especially appreciated on chats with a more technical nature.


I try to make a binary logistic regression model from 85871 samples. I used enter method. There are seven explanatory variables and all of them have significant in Wald Test. But, in Hosmer Lemeshow Test also significant, so my model doesn't fit the data right? What can I do in order to make my model fit? Is there another goodness of fit test?

I built a model with 9 categorical predictor variables. Using SPSS, my omnibus test was significant ($\chi^2$=220.01), my -2loglikelihood was 1335.2 (Nagelkerke $R^2$ 0.231), but my Hosmer and Lemeshow Test was significant (chi-sqr=16.2, p=0.042). My sample size is n=1199.  Is it problematic to proceed with this model, despite lack of fit?  I tried removing one of my binary predictor variables, and noticed that in the new model my Hosmer Lemeshow Test was significant (p=0.198), but my -2loglikelihood increased to 1442.2. Is there a trade off between Hosmer Lemeshow and -2loglikelihood?  How do I decide which model is appropriate?   My method for building this model was originally entering in all my predictor variables of interest, and examining the adjusted ORs of my variable of interest. Is my model a poor fit?  Additionally, how does one go about testing for multicollinearity when your predictor variables are all categorical (in other orders, calculating VIF is not possible). I was told in class that as long as the standard errors of Beta coefficients are less than 2 there is no reason to suspect multicollinearity, but I am not sure if this is sufficient?


I have a linux system and updated alsa from 1.0.23 to 1.0.25, It works as expected.  Steps which I performed to compile:  ./configure make  make install  Now , I have 100's of client machines in which I need to deploy this ALSA update. But, these machine does not have make/setup tools install.  To deploy this update what is the best way?  I even tried creating a package using CHECKINSTALL.  So, with created package I deployed it in 5 machines, in 3 machines the driver got updated and 2 machines reports no information on soundcard.  Am i missing something.

I have always had a problem installing and removing compiled software, so I have decided I would like to build software from source into a .deb package for easier installation/removal.  I would like to know of an easy and short way to build source into a .deb package, as an end user.  I have tried:   , which did not work for me This  guide, but I found it too long
