11,917,086 | I have created a JavaScript function which will return data containing 2 URL's. And I would like to insert these into the HTML code.
e.g. the return URL values are
JavsScript file
```
http://www.domain.com/javascript.js
```
CSS file
```
http://www.domain.com/buttons.css
```
I need to insert these into the code as:
```
<link rel="stylesheet" type="text/css" href="return URL value" />
<script type="text/javascript" src="return URL value"></script>
```
How can I do that?

| You can load external css (and also js) files dynamically using javascript. Just create the appropriate `<link>` element using javascript.
```
var url = computeUrl(); /* Obtain url */
var link = document.createElement('link'); /* Create the link element */
link.setAttribute('rel', 'stylesheet'); /* Set the rel attribute */
link.setAttribute('type', 'text/css'); /* Set the type attribute */
link.setAttribute('href', url); /* Set the href to your url */
```
At the moment, we have just created element
```
<link rel="stylesheet" type="text/css" href="your url">
```
And we have stored it in the variable `var link`. It is not over, the `<link>` is not part of the `DOM` yet.
We need to append it
```
var head = document.getElementsByTagName('head')[0]; /* Obtain the <head> element */
head.appendChild(link); /* Append link at the end of head */
```
And it is done.
In the very similar way, you can dynamically add external javascript resource. Just use `<script>` tag instead of `<link>` tag. | You can easily add nodes to the head element using javascript:
```
link=document.createElement('link');
link.href= your_css_href_function();
link.rel='stylesheet';
link.type='text/css';
document.getElementsByTagName('head')[0].appendChild(link);
```
And the same for your javascript tag:
```
script=document.createElement('script');
script.src= your_javascript_src_function();
script.type='text/javascript';
document.getElementsByTagName('head')[0].appendChild(script);

6,969,482 | I got a side bar (fixed on the right side) which is made with 3 images, `Top.png`, `Mid.png`, `Bot.png`. I was wondering if there is a way to load those 3 images during runtime and create/merging into a new one (`sideBar.png`), without saving it to the HD.
The point is, as I don't know the height of the screen, I am placing the Mid image as many times as it is needed to fill the space between the `Top.png` and the `Bot.png`.
Using:
* Javascript
* HTML 5
* CSS 3
EDITED:
and the CSS, its the same for all 3 parts... it only changes the url, name and position:
```
$("#Mid").animate({right: "-230px",}, 500 );
$("#Top").animate({right: "-230px",}, 500 );
$("#Bot").animate({right: "-230px",}, 500 );
#Bot {
position: absolute;
top:495;
right:0;

| This seems truly unnecessary. I'd recommend using CSS attribute `repeat-y` and building your HTML and CSS structures in such a way the images will mesh. This is not the purpose of JavaScript. | You haven't shown the HTML markup, but I'm guessing you should put the three images in a container div and animate the container div with one animation, not three. Then, there will not be anything out of sync during the animation. |

| I have Xcode 4.3.2, which still has severe problems with undo/redo -- it will usually crash after one or two redo! Just before it crashes, it will usually do some nonsense edit.
---
*Added*:
I have experimented with the tip by Walt to turn off line numbers. However, I have not seen any significant drop in crash frequency. However, going slowly seems to at least reduce the crash frequency, but it is absolutely no guarantee -- it may crash even after an extremely simply small undo.
(I usually get anywhere from 1 to a dozen crashes a day, but since I try to avoid undo, especially several consecutive undo, the crash frequency has dropped somewhat.)
A crash may come on either undo or redo, with a slightly higher crash frequency for redo. Sometimes the crash comes after just a simple paste with no preceding undo/redo.
I have also experimented with changing font scheme to a very simple one, but it does not help.
My only tip would be: when you see that e.g a paste, or entered text, is inserted at the wrong place, try to save (or ignore that step), then chose Revert Document. Sometimes that trick works, sometimes not (and if not, it will crash). Sometimes it has helped by switching to another file and then back.
Also, if you want to undo just to inspect what the previous thing was, save before the undo, then, rather than redo, it may be slightly safer to Revert Document (but it is by no means any guarantee).
After a refactor, the window's fonts often look garbled. In this case, it has always helped to switch to another file and then back.

| I have the same issue with Xcode 4.3.2, specifically the screen starts going garbled and if you are showing line numbers in your editor those will get messed up to then click somewhere else and *crash*.
Few quick helpful tips I have found:
1. Option-Command-S *before* you Command-Z (Save All) [in case it crashes you don't lose work]
2. If you do undo and you see it's messing up, open up another text file, then click back on the messed up file and it's now all better.

| I have Xcode 4.3.2, which still has severe problems with undo/redo -- it will usually crash after one or two redo! Just before it crashes, it will usually do some nonsense edit.
---
*Added*:
I have experimented with the tip by Walt to turn off line numbers. However, I have not seen any significant drop in crash frequency. However, going slowly seems to at least reduce the crash frequency, but it is absolutely no guarantee -- it may crash even after an extremely simply small undo.
(I usually get anywhere from 1 to a dozen crashes a day, but since I try to avoid undo, especially several consecutive undo, the crash frequency has dropped somewhat.)
A crash may come on either undo or redo, with a slightly higher crash frequency for redo. Sometimes the crash comes after just a simple paste with no preceding undo/redo.
I have also experimented with changing font scheme to a very simple one, but it does not help.

| The problem stems from the collision between Prototype and jQuery over the symbol "$". You're going to have to make one or the other of them relinquish it.
With jQuery, you do it like this:
```
jQuery.noConflict();
```
right after including the library:
```
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js'></script>
<script>jQuery.noConflict();</script>
```
Once you've done that, all the code that expects "$" to mean "jQuery" will have to explicitly use the global name "jQuery" instead of "$".
A better solution would probably be to find a way to avoid using two large JavaScript frameworks on the same page. Both of them have large ecosystems, so it's very likely you can find the tools you need and only rely on one of them. | You are using prototype.js and jQuery without using jQuery's [noConflict()](http://api.jquery.com/jQuery.noConflict/), what results in a conflict when using `$()` |
29,933,386 | I have a large mysqldump (4+ gigs), and we have an archive type table which [suffers from this bug](http://bugs.mysql.com/bug.php?id=37182) Net result is that I need to reset the AUTO\_INCREMENT counter to zero. Did manage to do the replacement, but it was ugly, involving splitting the file into smaller chunks, then grepping to find the table, looking to see the number I wanted to change and then using `sed` on the original file to replace just that match on the auto increment. Like I said, horrible, but it worked.
So - I have tried to decipher multiline sed and didn't get that far. What I want to do is to seek to the table name I'm interested in, and then from that point find the next `AUTO_INCREMENT=` , and then match the number in it, and make it zero. Here's the table: (assume there is scads of data before this point, and after it)
```
DROP TABLE IF EXISTS `archive_exported_problems`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `archive_exported_problems` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`export_id` int(11) DEFAULT NULL,
`problem_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=ARCHIVE AUTO_INCREMENT=478 DEFAULT CHARSET=latin1;
```
What I want to do, is to (automatically) scan the file until it matches
```
(?:CREATE TABLE `archive_exported_problems).*?AUTO_INCREMENT=(\d+)
```
(regex which seems to work) and then replace the capture group with 0

| If `perl` is an option then it is easier using `DOTALL` flag in `perl` like this:

`problem_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=ARCHIVE AUTO_INCREMENT=0 DEFAULT CHARSET=latin1;
```
Options used are:
```
-00 # slurps whole file
(?s) # enable DOTALL flag for regex
``` | Consider this:
```
$ sed -r '/CREATE TABLE `archive_exported_problems`/,/AUTO_INCREMENT=/ {s/(AUTO_INCREMENT)=[[:digit:]]+/\1=0/;}' file

/*!40101 SET character_set_client = utf8 */;

`export_id` int(11) DEFAULT NULL,
`problem_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=ARCHIVE AUTO_INCREMENT=0 DEFAULT CHARSET=latin1;
```
For Mac OSX (BSD), try:
```
$ sed -E -e '/CREATE TABLE `archive_exported_problems`/,/AUTO_INCREMENT=/ {s/(AUTO_INCREMENT)=[[:digit:]]+/\1=0/;}' file
```
### How it works
* `/CREATE TABLE`archive\_exported\_problems`/, /AUTO_INCREMENT=/`
This restricts the subsequent commands to ranges on lines that start with a line containing `CREATE TABLE 'archive_exported_problems'` and end with a line containing `AUTO_INCREMENT=`.
* `s/(AUTO_INCREMENT)=[[:digit:]]+/\1=0/`
This performs the substitution that you wanted.
### Limitation
This approach assumes that the `CREATE TABLE` phrase and the `AUTO_INCREMENT=` phrase will never be on the same line. If that is not true, we need to make some minor changes. |

| Okay, it looks like it was a problem with the configuration of my system. I post the answer here because it's not obvious why one progress bar animation would work but not another.
In System Properties / Performance Options, I had "Animations in the taskbar and Start Menu" disabled. This option apparently disables the "indeterminate" animation but not the regular one. By re-enabling the option, the indeterminate animation works. | This happened to me too. In the code, I have a Form A that shows a Form B (which Form B in the OnLoad event calls SetProgressState) and after that Form A calls the method Close to itself, and when it was in Indeterminate mode it didn't show anything!
Surpringsly, if I close first Form A and then show Form B, the problem is solved!

| A lot of good information from everyone, and I really do appreciate the efforts given. But not the answer i was looking for. Which maybe means, that what i want does not exist, yet.
So i may have to roll my own solution...Or maybe integrate with another existing app...

| I have been heavily using this type of a setup for several years by email only, and the last 3 years with a Bug Tracking Software.
I must say, the bug tracking software has made my life so much more peaceful. Nothing is left, forgotten, or slips through the cracks. It's easy to find trends in errors, and remember "all the times" it happened.
Our setup is like this:
**1) Coldfusion + Appropriate framework with error reporting** - It doesn't matter what you use. I have used Fusebox extensively and am making the transition to ColdBox. Both are very capable, in addition to Mach-II, FW/1, Model-Glue, etc. The key part you have to find in them is their ability to catch "onError", usualy in the application CFC.
**2) Custom OnError Script** - Wherever an error occurs, you want to capture the maximum amount of information about that error and email it in. What we do is, when an error occurs, we log the user out with a message of "oops, log in again". Before logging them out, the application captures the error and emails it to Fogbugz. Along with it, at the top we include the CGI variables for the IP address, browser being used, etc. Over time you will find the things you need to add.
**3) Routing in Fogbugz.** A 2 user version of Fogbugz is free, and hosted online. There are two main ways to submit bugs. One is to email one in at a time. So if an error happens 2000 times, you get 2000 emails, and 2000 cases. Not always the best to link them together, etc. They have a feature called BugzScout, which is essentially an HTTP address that you do a form post to with cfform with all of the same information you would have put into the email. There's plenty of documentation on this and something I've always wanted to get around to. I had a scenario of 2000 emails for the first time happen a few weeks ago so I'll be switching over to this.
Hope that helps. Share what you ended up doing and why so we all can learn too! | There are few in CF411 list: [Bug Tracking/Defect Tracking/Trouble Ticket/Help Desk Tools Written in CFML](http://www.carehart.org/cf411/#bugcfml) |

You may be able to find a hosted service and use either email or web services to create the ticket using onError. With that said, a simple issue tracking app could be created for your site using the same DB used to drive the content. 2 or 3 tables would take care of the data storage and you're already using CF so the application layer is already there.

Thank You all. | Hard question to answer not knowing what kind of restrictions are there? Do you have any permissions to install anything? Also most bug-tracking systems require some kind of database support.
I have a suggestion. You can put in place a basic bug-tracking system, that just allows people to create tickets, and allows you/someone else to close it.

| You can use UIButton instead of UIImageView in tableview cell. Use following code for getting single and double tap.
```
//add target for your UITableViewCell's button
[aBtnThumbObj addTarget:self action:@selector(btnThumbClickDouble:) forControlEvents:UIControlEventTouchDownRepeat];
[aBtnThumbObj addTarget:self action:@selector(btnThumbClickSingle:) forControlEvents:UIControlEventTouchUpInside];
-(void)btnThumbClickSingle:(UIButton*)sender
{
[self performSelector:@selector(singleTapOnButtonSelector:) withObject:sender afterDelay:0.2];
}
-(void)btnThumbClickDouble:(UIButton*)sender
{
[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(singleTapOnButtonSelector:) object:sender];
//Your implementation for double tap
}
-(void)singleTapOnButtonSelector:(UIButton*)sender
{
//Your implementation for single tap
}
``` | These two lines of code work for me:
```
tapGesture.cancelsTouchesInView = YES;
tapGesture.delaysTouchesBegan = YES;

4,505,103 | I'm wondering if there is a way to calculate arrangements for this problem without enumerating all possibilities.
There are 4 work-pieces that 4 guys A, B, C, D work on during a single day. At the end of the day each person transfers his assigned work-piece to another person. Each person works on only 1 work-piece during a day. How many arrangements of transfer are possible?
E.g. A can transfer his workpiece to C (AC), or A can transfer it to B, or A can transfer it to D, but A can't transfer it to A.
One arrangement is:
```
AC (A transfers to C)
BD (B transfers to D)
CA
DB
```
For the purposes of this question the order of transfer (e.g. whether AC is written in line above BD) doesn't matter, and the above arrangement is considered same as: `CA, BD, DB, AC`. | 2022/08/03 | [

| These are all the permutations of a set with 4 elements without fixed points. For a set with $n$ elements see: [Fixed-point-free permutations](https://math.stackexchange.com/questions/41949/fixed-point-free-permutations) or the many equations for it ($!n$) on wikipedia <https://en.wikipedia.org/wiki/Derangement>. | Alternative approach:
Person-A can transfer to anyone of three people.
So, there will be an initial factor of $(3)$.
Now, you can assume, without loss of generality, that Person-A transfers to Person-B.
Now, there are 3 people that Person-B might transfer to:
* If Person-B transfers to Person-A, then the transfers are set, since Person-C and Person-D must then exchange.
* If Person-B transfers to Person-C, then Person-C must transfer to Person-D (or else no one is transferring to Person-D).
* Similarly, if Person-B transfers to Person-D, then Person-D must transfer to Person-C.
Therefore, if you know that Person-A transferred to Person-B, then there are $(3)$ possible ways that the transfers can be completed.
Therefore, the total number of satisfying groups of transfers is
$$3 \times 3.$$ |
220,282 | In [agar.io](http://agar.io), sources of mass are abundant. The little pellets of nutrition spawn frequently. The problem is that there are no places for mass to go - which it must do otherwise the game would run out of space. Even when people log out, their cell remains stationary until it is eaten. I'm assuming then that mass must be lost in one of the following situations:
* When splitting (via space)
* When popped (via a spike)
Is this the case? If so, how much of my total mass is lost when this happens? | 2015/05/21 | [

| Thanks to [Ardaozkal](https://gaming.stackexchange.com/users/87186/ardaozkal) his comment I was able to do some research.
There are a couple of reasons why the game never runs out of space,
* When just going around not collecting any orbs you seem to lose a bit off mass. The amount of mass you lose seems to be bigger if you have a lot.
* When pressing `W` you shoot out a bit off mass, picking it back up will not give you back the amount you lost.
*Splitting up or hitting a spike does not seem to make you lose anything other then your shape.* | You eject 13 mass every time you press w or, on the mobile version, click the target button, but your cell loses 18 mass, so self feeding, or ejecting mass and then eating it again, will cause you to lose mass, not stay the same. You can eat viruses when you are split into 16 pieces, and you gain 100 mass every time you eat a virus, even if you aren't split into 16 pieces. You can eat viruses by having 2 cells that can eat the virus and running one of them into the virus, so you end up with 16 cells, and you can then go around eating viruses, but you have to be careful, since other players can eat your smaller pieces, and then eat you completely. You can make new viruses by ejecting seven times into an existing virus, and a new one will be shot out in the opposite direction of the last pellet you shot out. This is very useful for splitting bigger players so that you can eat them. Try using keyword skins, which means entering a name like Earth, which will give you a Earth skin. There are a lot more of these keyword skins, and you can make your own skin it the store or other places. It costs 90 DNA, though, so try to save up. Hope this helps! |

| As a member of both communities, I think that kind of question would be better suited for Super User. Wikimedia Commons isn't a webapp *per se*, and you're asking about how to download files to the computer, which places your question more in SU's domain.
Please note that your question is more likely to be answered if you describe some of the research you have done about this problem; "gimme teh codez" posts are generally frowned upon. | The [Wikimedia Commons Help Desk](http://commons.wikimedia.org/wiki/Commons:Help_desk) is probably a better place to ask. You're guaranteed to be able to interact with experts on the software there.
If you're bound and determined to ask on a Stack Exchange site, then I think this one or [Super User](http://superuser.com) are appropriate; I just don't know that you'll get the answer you need.

``` | There is another (possibly easier) way to connect the view pager with the tab layout-
First, in your `PrefAdapter` class, override the `getPageTitle()` method and return your tab titles for the respective tab positions from there.
In your `PrefMainActivity` class, remove all the lines like-
`tabLayout.addTab(...)`
Add the following line instead-

4,940,982 | My goal is to use a [Greasemonkey-style user script](http://www.chromium.org/developers/design-documents/user-scripts) in Google Chrome to enable remembering of passwords on a specific form that has the `autocomplete="off"` attribute set.
Chrome's developer tools indicate that `autocomplete="on"` is being successfully set by the script, but this does not have the expected effect of allowing the storage of passwords on the form.
Why doesn't this work?
---
Example
-------
Chrome offers to remember passwords entered on this test page (Expected):
```
<html><body><form action="">
<input type="text" name="username" />
<input type="password" name="password" />
<input type="submit" name="submit" value="Log In" />
</form></body></html>
```
Chrome does not offer to remember passwords entered on this test page (Expected):
```
<html><body><form action="">
<input type="text" name="username" />
<input type="password" name="password" autocomplete="off" />
<input type="submit" name="submit" value="Log In" />
</form></body></html>
```
Chrome's *Inspect Element* tool reveals a successful modification of the above test page by the user script (Expected):
```
<html><head></head><body><form action="" autocomplete="on">
<input type="text" name="username" autocomplete="on">
<input type="password" name="password" autocomplete="on">
<input type="submit" name="submit" value="Log In">
</form></body></html>
```
Chrome still does not offer to remember passwords after this modification (Unexpected). | 2011/02/09 | [

| One of my favorite jQuery form validation plugins has to be [Happy.js](http://happyjs.com/). It's very lightweight and extensible, and requires very little effort to get working. | The standard way to validate with jQuery is to just use the [jQuery validation plugin](http://docs.jquery.com/Plugins/validation). It's widely used, regularly maintained, easy to use and mature. There's no point in rewriting something that's already been done. You can obviously use this plugin to control form submission. |
332,095 | I am running a MacBook Pro Early 2015 13" on High Sierra 10.13.5, and keep getting the "X disk cannot be ejected because one or more programs might be using it" message, when apparently there is no program using that disk (not even Dropbox, Preview).
It happens sometimes when I try ejecting an external thunderbolt Drive, and always when ejecting any .sparseimages
I only managed to "solve" this issue and be able to eject the disks by going into Terminal and "respringing" Finder:
```
killall Finder
```
However, I find this solution really inconvenient considering how often I use External Drives and disk images.
I would appreciate if anyone knows any other possible cause or solution, or if my solution is better than forcing the disk to eject.
Edit: After checking what processes were running, it seems there are "cloudd", "diskimage" and "QuickLookUIService" processes using a video file from the sparsedisk that are preventing me from ejecting the mounted sparseimage.

| Often when a drive is plugged in Spotlight begins to index the entire drive. While this is occurring Spotlight is "using" the drive and therefore can't be ejected.
Try adding a Spotlight exception:

I need to check if a particular textbox has the focus or not using jQuery. So my code is like this, but it is not working:
```

My use-case is this: I have a textbox which should be shown or hidden when the `#lastname` textbox gains or loses focus. However, if the `#lastname` textbox loses the focus to the other textbox, the latter should remain visible until it loses focus as well.

9,073 | **A bit of backstory**
My parents are separated and my Dad has a long-term partner who he has been with for over 10 years now. She (my Dad's partner, let's call her Eve) has a close group of friends who she sees on a regular basis. One of Eve's close friends (let's call her Annie) works at the same place as me, in different departments but we occasionally see each other at lunchtime.
Someone in my family, Adam, has a mental health condition which sometimes means the way they behave is not the most polite, can come across as rude etc. I mention this because it has caused issues in the past. Eve has found Adam's behaviour to be 'unacceptable', has told my Dad, who has then told Adam which has caused a lot of grief and loss of trust. I think this goes to demonstrate how sensitive Eve can sometimes be about a person's perceived behaviour, which is why I want to avoid as much as possible any conflict.
**My Problem**
Adam had recently been going through a 'down period', whereby I mean their mental health was not in good shape for several reasons. I would talk to my (our) Dad about this when I would see him. Sometimes Eve would be there too, but I felt like there was no reason not to trust her with the information. In essence, Adam was not sure if he wanted to go on a family holiday because he wasn't feeling great, I felt it was important to tell them because they would need to be aware and available had that been the case.
So, on a couple of occasions at work, I have bumped into to Annie at lunchtime and she has asked me about a specific 'event' that either myself or Adam would have discussed with my Dad. My Dad may have discussed this with Eve which I don't see a problem with unless it was explicitly stated to be confidential between my Dad and Adam. I do however take issue with this for several reasons:
1. The information I shared with them, was shared with confidence that it would be private between those present. It was not explicitly stated but I definitely would expect that to be the case.
2. I hardly know Annie. She is a lovely person but we are not close and she isn't a close family friend. On the contrary, she is only friends with Eve, not my family and certainly not someone who I would divulge such personal information to.
3. When Eve and Annie normally see each other it is with a large group of friends. So if Annie knows about this then it is likely that everyone else present at the time also knows. People who I don't even know. And who knows who else could have been told.
As nice as Annie is, and as much as I like her, it is not her (or any of Eve's other friends') business to know the inner workings of my family or Adam's personal information and I need to make sure that Eve doesn't do this sort of thing again.
This has only happened twice. With the example that I mentioned above and with another example.
As mentioned earlier Eve has a tendency to be very sensitive about matters such as these. How can I go about asking her not to share such information? In the meantime, I know that I can refrain from saying anything with her present, but I know that I **do** need to tell my Dad important things. But then I would have to tell him explicitly not to share this with Eve which raises the same problem.
This is especially important to me because if Adam were to find out about how Eve had been 'spreading his secrets' it would cause a lot of conflicts and unnecessary grief in our family.
How can I make Eve know that she can not be spreading personal family information such as this with strangers?

| This is a tough one. There are no guarantees Eve will honor your request. Usually, people who spread information to others, whether you consider it gossiping or not don't realize it's a big deal and if this is how they are they will keep doing it.
**Approach Eve and tell her what her friend Annie mentioned/asked about Adam.** Ask her calmly to not share your family's private matters (e.g stuff about Adam) to anyone even Annie. You could explain what you said in your question about both Eve and Annie discussing such matters around other women who might also spread the information and so on. Depending on your relationship with Eve you could politely tell her that you don't like that this is causing problems to Adam and you wish she stopped the behavior.

You could elaborate more about the importance of confidentiality in discussing someone's mental health. Adam hasn't agreed nor given permission and he feels uncomfortable to the point his health is affected.
Keep in mind that even if Eve respects your request in theory she could still tell Annie and ask her not to mention anything to you from now on...
If you feel this is really damaging to Adam ask for your dad's help. Either don't talk about Adam when Eve is around or involve your dad in a solution by mentioning what happened with Annie. Is he able to convince Eve that she needs to keep your family's matters private?
If after asking Eve she keeps spreading information e.g about Adam, confront Eve and tell her that it has made it difficult for you to trust her and you won't be sharing personal information again. You could ask your dad to do the same but he's been with Eve for many years and it's hard to exclude her from information involving the family. | Tell Eve what you told us. There's no need to ask her to stop sharing information, merely to mention the outcome of sharing the information (ie, Adam may be upset) and that she should discuss it with Adam so he knows what she's shared, who she's shared it with, and what he'd like her to do in the future.
>
> Eve, Annie has approached me at work a few times to discuss sensitive family information, for instance Adam's mental health. I understand she's your friend and perhaps you need someone to talk to about this, but I'm concerned that if Adam knew his mental health was being discussed with others outside the three of us, even in confidence, it would be very upsetting to him.
>
>
> I'll tell Annie directly that I don't want to discuss personal family matters with her. I'd appreciate it if you would discuss this with Adam, letting him know what you've shared with others and why. I want to avoid him finding out later from someone else that his information may have spread further than he'd prefer, and he may have specific desires for how and with whom to share this information.

Your command (`sed -i -f remccoms3.sed`) leaves out the `-n` argument.
The `-n` argument to `sed` is
>
> -n, --quiet, --silent
>
>
> suppress automatic printing of pattern space
>
>
>
so without that you get the normal printing *and* the script's printing. | Don't use that script. Its cute and some people may find it interesting as a mental exercise but it's buggy (as it says itself it's been `bugfixed to some extent`!), absurdly complicated and a completely inappropriate application for sed.
To remove comments from all versions of C or C++ code just use the script at <https://stackoverflow.com/a/13062682/1745001> and pass the appropriate C or C++ version to `gcc` as one of it's arguments.
Also if you want to retain blank lines instead of having them removed (I first wrote this tool for counting NCSL so removing blank lines was desirable) along with the comments then just tweak the sed to make them not look like blank lines to gcc:
```
$ cat decomment.sh
[ $# -eq 2 ] && arg="$1" || arg=""
eval file="\$$#"
sed 's/a/aA/g;s/__/aB/g;s/#/aC/g;s/^[[:space:]]*$/aD/' "$file" |
gcc -P -E $arg - |
sed 's/aD//;s/aC/#/g;s/aB/__/g;s/aA/a/g'
$ ./decomment.sh file
#include <fstream>
#include <sstream>
#include "Data.h"
#include "utility.h"
std::ifstream input_file;
```
or if you have an ANSI C version input file where comments cannot start with `//`, just tell the tool that:
```
$ ./decomment.sh -ansi file
#include <fstream>
#include <sstream>
//Other files
#include "Data.h"
#include "utility.h"
// Open input file
std::ifstream input_file;
```
Here's an example of a C construct (the trigraph `??/` means `\`) that the enormous sed script won't handle correctly but the small sed+gcc script will handle just fine because `gcc` includes a parser for the language, not a bunch of regexp estimations for it:
```
$ cat tst.c
//C hello world example
#include <stdio.h>
/??/
* This is a comment using trigraphs */
int main()
{
printf("Hello world\n");
return 0;
}
```
.
```
$ ./remccoms3.sed tst.c
#include <stdio.h>
/??/
* This is a comment using trigraphs */
int main()
{
printf("Hello world\n");
return 0;
}
```
.
```
$ ./decomment.sh -trigraphs tst.c
#include <stdio.h>
int main()
{
printf("Hello world\n");
return 0;
}

74,256,644 | I am new to programming in C and I am doing some activities for my first year in CS. The following activity consists of calculating the sum of squares of the digits of a user input number and the output should be as follows:

Number: 1234

n=123; sum=25
n=12; sum=29
n=1; sum=30
Result: 30

I have got it for the most part, the thing that I don't understand is how to store a value in a variable, update said variable and print the result, all whilst being inside a loop.
This is what I came up with:
```
int main() {
int num,i,sum=0,result,square;
printf("Calculate the sum of the square of the digits of a number\n" );
printf("Number:");
scanf("%d", &num);
i=0;
while(num>i)
{
sum=num%10;
square=sum*sum;
printf("\nn=%d; sum= %d",num,square);
num=num/10;
}
result=sum;
printf("\nResult: %d",sum);
return 0;
}

| Write something like the following
```
int digit = num % 10;
square = digit * digit;
sum += square;
printf("\n=%d; sum= %d", num, sum );
```
Pay attention to that the variable i is redundant:
```
i=0;
while(num>i)
```
just write
```
while ( num != 0 )
```
Also introducing the variable `result` is redundant and does not make sense because it is used nowhere. | You need a variable, keeping track of the input number (num), a variable keeping track of the sum ('sum') and a variable with the current digit (digit). Every iteration, you can calculate the digit, square it and add it to the sum. The `a += b` operation is equivalent to `a = a + b`, in case you are wondering. The same is for `a /= b`. Also a concept you can use (but don't have to), is implicit boolean conversion. When using a comparison (like num != 0 or num > 0) you can replace it with the number itself. In C, 0 equals false and everything else equals true.
```
#include <stdio.h>
int main() {
int num, sum = 0;
printf("Calculate the sum of the square of the digits of a number\n" );
printf("Number:");
scanf("%d", &num);
while (num) { // is equal to num != 0
int digit = num % 10;
sum += digit * digit;
printf(" n=%d; sum= %d\n", num, sum);
num /= 10;
}
printf("Result: %d\n", sum);
return 0;
}
```
EDIT:
Some people prefer to use `num != 0` or `num > 0`, because it is more readable. You should stick to it too for the start, until you are paid to confuse your coworkers. |

| I had a similar problem with my GTX 1080 when installing Ubuntu 16.04. It seems that 16.04 does not support the latest Nvidia GPUs. I finally managed to install Ubuntu 16.04 along side with Windows 10 dual boot with my GTX 1080 unplugged. What I did is as follow.
1. Before you install Ubuntu, go to BIOS setting and disable the GTX GPU. You may need to go through the BIOS settings for sometime to find the right option (something like IGX?).
2. Note that before you reboot, you need to switch your monitor's cable to the motherboard video output, since after reboot, the GTX GPU would be disabled and you would not see anything.
3. After that, choose the install media with UEFI, and go through the installation procedure as usual. The display should be alright.
4. At the position where it asks on which device you want the Ubuntu installed, choose manual setting (the `something else` button?). And make partitions as you like. But remember to choose the whole device (i.e. `/dev/sda` or `/dev/sdb`) to install grub. DO NOT choose something like `/dev/sda1`.
5. After the installation finished, reboot without changing graphical output device.
6. When you are in your newly installed Ubuntu, open a terminal and install the appropriate Nvidia driver. You may check [this question](https://askubuntu.com/questions/795547/ubuntu-16-04-unable-to-boot-with-gtx-1080) for more details. It's basically `sudo add-apt-repository ppa:graphics-drivers/ppa` `sudo apt-get update` and find the right driver for you. Check [this](https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa) also.
7. Finally, reboot and change the graphical output device back to your GPU and everything should work normal. You can type `nvidia-smi` in a terminal to check if the driver is working.
One of my friend tried to install Nvidia driver from Ubuntu system setting. You may look into that as well. As for me, the above procedure works fine. | **1. Make sure that your GRUB is set right:**
---------------------------------------------
**a.For Non UEFI**, Download boot-repair-disk <https://sourceforge.net/projects/boot-repair-cd/files/> and repair the grub maybe is not installed on the GNU/Linux partition, do a repair just to be sure.
**b.For UEFI** see <http://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a-ubuntu-live-cd>.
**2. Use the latest Nvidia Proprietary Drivers IF the Free-Open-Source-Drivers not working like it should:**
------------------------------------------------------------------------------------------------------------
Go to <https://www.nvidia.com/Download/index.aspx?lang=en-us> and **download the latest Proprietary drivers** according to your Nvidia card.
Then press **Ctrl+Alt+F1**
Type your username and password
```
sudo service lightdm stop
```
`cd /home/YoUrUsErNaMe/Downloads` (or anywhere that is the Nvidia \*.run file that you have downloaded)
`sudo sh NVIDIA-Linux-x86*`(Or type `sudo sh NVIDIA-` and **press Tab** and then **Enter**)
**Choose yes to:** Automaticly nvidia drivers to stop nouveau (default driver)
```
sudo shutdown -r now
```

IF you see bad resolution is totally OK nouveau was disabled by Nvidia.

896,555 | Today I tried several times to install Ubuntu but I have some GPU problems.
I have a bootable stick. When I boot in UEFI mode all its normal but the installer isn't able to install the boot loader.
When I boot in leagacy mode I'm able to install Ubuntu but only when I unplug my GPU GTX 1070.
When I don't do that, I get an this initialization error from the installer:
```
3.021954] nouveau 0000:01:00.0: unknown chipset (134000a1)
```
I installed Ubuntu normally without the GPU. I installed the drivers, rebooted, shut down, pluggeed in the GPU and tried to boot but it got stuck at:
```
/dev/mapper/isw_bdifbbjbai_Raid0p3: clean, 191449/8855552 files, 1677252/34500448 blocks

What should I do? When I unplug the GPU I can boot easily, but I need my GPU! :D

65,056 | I am having trouble inserting pictures into my latex document at a specific point. Currently I have the two figure environments in the text but they are printed at the back of the document, after the bibliography. Am I missing something?
The pictures are both supposed to be full page-sized rather than a traditional smaller figure or float. I might be wrong in using the figure environment in this case, but I am not sure.
```
\documentclass[12pt, a4paper, twoside]{article}
\usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}

| Since the images must go at a specific position, it's not convenient to use a floating environment; you can use `\captionof` from the [`capt-of`](http://www.ctan.org/pkg/capt-of) or [`caption`](http://www.ctan.org/pkg/caption) packages to give your figures a caption:
```
\documentclass[12pt, a4paper, twoside]{article}
\usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}
\usepackage[T1]{fontenc}
\usepackage[demo]{graphicx}
\usepackage{caption}
\begin{document}
I have some text here. Then pics.
\clearpage
{
\centering
\includegraphics[scale=0.75, angle=90, width=\textwidth]{hamlet.jpg}
\captionof{figure}{cool picture}
\clearpage
\includegraphics[scale=0.75, angle=270, width=\textwidth]{kinglear.jpg}
\captionof{figure}{cool picture 2}
}
\clearpage
some more text here
\end{document}
```
The `demo` option for `graphicx` simply replaces actual figures with black rectangles; do *not* use that option in your actual document.
Depending on how tou are controlling the size for the images, you could additionally wrap each image and its caption using a `minipage` to prevent an undesired page break; something like
```
\clearpage
\noindent\begin{minipage}{\textwidth}
\centering
\includegraphics[scale=0.75, angle=90, width=\textwidth]{hamlet.jpg}
\captionof{figure}{cool picture}
\end{minipage}
\clearpage
\noindent\begin{minipage}{\textwidth}
\centering
\includegraphics[scale=0.75, angle=270, width=\textwidth]{kinglear.jpg}
\captionof{figure}{cool picture 2}
\end{minipage}
\clearpage
``` | You're not doing anything wrong by using the `figure` environment. Since you mention that the figures are meant to take up a full page, you could load the `afterpage` package and use its `\afterpage` command to defer typesetting the figures until the next page break occurs anyway; this will relieve you from having to figure out when to issue a `\newpage` or `\clearpage` command. Here's what I'd do:
```
\documentclass[12pt, a4paper, twoside]{article}
\usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}
\usepackage[T1]{fontenc}
\usepackage[demo]{graphicx} % delete 'demo' option in real document
\usepackage{afterpage}
\begin{document}
I have some text here. Then pics. some more text here
\afterpage{
\clearpage % flush any pending floats
\begin{figure}[p] % use [p], not [ht!]
\centering
\includegraphics[scale=0.75, angle=90, width=\textwidth]{hamlet.jpg}
\caption{cool picture}
\end{figure}
\clearpage
\begin{figure}[p] % use [p], not [ht!]
\centering
\includegraphics[scale=0.75, angle=270, width=\textwidth]{kinglear.jpg}
\caption{cool picture 2}
\end{figure}
\clearpage % force both floats to be typeset
} % end of scope of \afterpage instruction
some more text here
% this may or may not be typeset on the page prior to
% the two floats-only pages, depending on how much
% space was left on the page when \afterpage is
% encountered.

74,310,316 | I'm learning C++ and I want to know if there is a way you can use variables defined in a class's constructor in a member function. I've tried looking online and in my textbook but I can't find a definitive answer. For example:
```
class Item {
public:
Item(std::string str) {
std::string text = str;
int pos = -1;
}
void increment() {
// how would I reference pos here?
pos++;
}
};
```

No, you can't. Variables defined in the constructor goes out of scope at the end of the constructor.
The normal way is to initialize *member variables* in the constructor. These can then be accessed in the member functions:
```cpp
class Item {
public:
Item(std::string str) : // colon starts the member initializer list
text(std::move(str)),
pos{-1}
{
// empty constructor body
}
void increment() {
pos++; // now you can access `pos`
}
private:
// member variables
std::string text;
int pos;
};
``` | You need to turn `text` and `pos` into private data members of the `Item` class.
*Private* because, if declared public, they could be easily overwritten making, for instance, redundant the `increment()` function, which is an undesirable side effect.
```
class Item {
public:
Item(std::string str): text{str}, pos{-1} {}
void increment() {
pos++;
}
/* text and pos are now private data members, hence need 'get' functions
in order to access their current value */
std::string& getText() {
return text;
}
int getPos() {
return pos;
}
private:
// text and pos made private members
std::string text;
int pos;
};

33,416,021 | I have been using Mendeley's Microsoft Word plugin to easily reference papers in my Mendeley Desktop library.
However, I've noticed that the IEEE format for the bibliography/citation is incorrect with regards to referencing conference proceedings and theses.
On the IEEE citation guide: <http://www.ieee.org/documents/ieeecitationref.pdf>
It shows that the city of the conference should be included in the citation of a conference paper. However, Mendeley's IEEE CSL file does not include this detail.
```
<macro name="event">
<choose>
<if type="paper-conference speech" match="any">
<choose>
<!-- Published Conference Paper -->
<if variable="container-title">
<group delimiter=", ">
<group delimiter=" ">
<text term="in"/>
<text variable="container-title" font-style="italic"/>
</group>
<text variable="event-place"/>
</group>
```
Should be changed to:
```
<macro name="event">
<choose>
<if type="paper-conference speech" match="any">
<choose>
<!-- Published Conference Paper -->
<if variable="container-title">
<group delimiter=", ">
<group delimiter=" ">
<text term="in"/>
<text variable="container-title" font-style="italic"/>
</group>
<text variable="publisher-place"/>
</group>
```
Since event-place is not a keyword that maps to the "city" field in Mendeley; the correct variable is "publisher-place". | 2015/10/29 | [

| Two options, use this formatted one that I just made, or follow the steps I did to make this change in the CSL Visual Editor.
**Just use the corrected file**
1. While in Mendeley Desktop, go to View menu, "Citation Style ->" and click "More Styles..."
2. Click on the tab "Get More Styles", and enter the following link into the "Download Style:" text box, then click Download
<http://csl.mendeley.com/styles/451326401/ieee-CS-edited>
Done!
**Make your own corrections**
1. While in Mendeley Desktop, go to View menu, "Citation Style ->" and click "More Styles..."
2. Right Click on IEEE and choose "Copy Style Link"
3. Open up a web browser, and paste the link and hit enter, it should download a file called "ieee.csl"
4. Open up a web browser that isn't Chrome, as this doesn't work in Chrome, and go to the page <http://csl.mendeley.com/visualEditor/>
5. Login using your Mendeley credentials
6. Click on the "Visual editor" tab at the top if it's not already selected.
7. Hover over "Style" and choose "Load Style..."
8. Browse and select the "ieee.csl" file that was downloaded earlier.
9. Under "STYLE INFO" and "Info", rename the Title to something new.
10. Navigate to the following

2,316 | There are some hadith listing Mubah actions that involve khayr. These are; flirting with the spouse, horse racing and marksmanship. I would like to know if marksmanship encompasses javelin throwing or not. Maybe someone can find and check the Arabic original of the hadith and share here the meaning(s) of the word used.
This might not look so important, but I believe if we could shift our Mubah activities to the ones mentioned in the hadith, we would kill two birds with one stone.

| The Arabic word *rimaya* رماية literally means *throwing*, but when it is unqualified it is used as a synonym for *shooting*, which at the time meant archery. In modern usage this has been extended to marksmanship in firearms.
But getting back to the hadith itself, looking at the context we can deduce that the *throwing* in question is of the martial kind (i.e. to aid in war). So at the time of the prophet that meant archery, since it was one of the most effective weapons of war at the time.
Applying this hadith in modern times, we find that archery (and javelin throwing) are no longer contemporary battle skills. So we have to assume that it now encompasses their modern equivalent, which is (as I stated earlier) firearm marksmanship. | Perhaps it becomes clear if we look at Volume 5, Book 58, Number 156:
>
> Talha was a strong, experienced archer who used to keep his arrow bow strong and well stretched. On that day he broke two or three arrow bows.

This seems to make it clear that this is referring to regular bow-based archery, suggesting that "throw" in the translation is being used simply to describe the flight of the arrow (which might more familiarly termed: to "loose" an arrow). |
64,039,448 | I was implementing the Oauth2.0 authentication using Google. I used react-google-login npm on the frontend to authenticate the user using Google Oauth2.0. I successfully created the CLient-id and secret under google cloud platform for my project, along with the URI as needed.
The frontend is running on default localhost:3000 and backend (node/express) running on localhost:9001 with proxy enabled on frontend to redirect the request to backend.
I was able to authenticate using Google more than 2 dozen times last night as i was working on the backend siginIn contoller. I was also able to add the user to my Mongodb after successful authentication from Google.

| In standard cosmology, the answer to the bolded question is "yes", while the answer to the second one is "no".
There is a way to define an absolute reference frame, in that any observer can measure the dipole moment of CMB radiation and determine the velocity with which they are moving through it (see section 2.1 in [this Planck paper](http://arxiv.org/abs/1807.06205), for example).
What this means is that the universe is not invariant with respect to Lorentz boosts, but it *is* ([at large enough scales](https://en.wikipedia.org/wiki/Cosmological_principle)) invariant with respect to rotations and shifts, so there is no center or preferential direction to speak of.
The existence of this "preferential" frame does not invalidate the general principle of relativity --- physics can be described in other frames just as well if we do a coordinate transformation. However, this particular one is interesting in that we can unambiguously refer to it from anywhere in the universe. | Is there a well-defined “speed relative to the universe" and is there a well-defined "central point" of the universe are 2 different questions.
As far as central point is concerned, there is indeed no such point.
Speed relative to the universe is also strictly not well-defined, but the frame of the cosmic background radiation is sometimes considered as some kind of stationary rest frame of the universe, relative to which other events can be described. But this is not a "privileged" frame of reference, just a convenient frame of reference to describe any kind of events anywhere in the universe. |

| Something no one else has mentioned yet: the **class** keyword has two different uses.

and indicating a class literal:
```

``` | The "extends" keyword can be for single inheritance (either implementation or "pure abstract class" aka "interface inheritance" in Java).
The "extends" keyword can also be used for multiple (interface) inheritance.
The ones who always argue that Java doesn't support multiple inheritance will hence have a hard time arguing that "extends" in those two cases is doing exactly the same thing.
Now I'm in the other camp: I consider that multiple interface inheritance is multiple inheritance and that implementation inheritance is just an OOP detail (that doesn't exist at the OOA/OOD level) and hence I consider that "extends" is really doing the same thing in both case and that hence my answer doesn't answer the question :)
