35,921,255 | What should ls $GOROOT and ls $GOPATH look like (not a repeat)? | This is not a repeat of this question:
http://stackoverflow.com/questions/7970390/what-should-be-the-values-of-gopath-and-goroot
I don't want to know what the values should be. I want to know what I should see when I type `ls $GOROOT` or `ls $GOPATH` into console. I'm pretty sure I set things up wrong following a tutorial almost a year ago, and I want to be able to confirm that these two are pointing to where they should be by simply checking that what they point to looks right.
Here's where I am right now. It looks like `$GOROOT` is pointing nowhere. I'm pretty sure it should be pointing at `usr/local/go`, but it would be a lot easier to confirm if I knew what the expected result of `ls $GOROOT` is supposed to be.
As for `$GOPATH` I'm not totally sure if my "workspace" is where all my go code is, or maybe just the github stuff, or maybe the particular folder I'm working within. I know it's supposed to point to my "work space," but I don't know what that work space I'm looking for looks like.

35,945,006 | Why didn't they design array index to start from 1? | <p>In many programming languages, the array index begins with 0. Is there a reason why it was designed so?</p>
<p>According to me, it would have been more convenient if the length of the array was equal to the last index. We could avoid most of the <code>ArrayIndexOutOfBounds</code> exceptions. </p>
<p>I can understand when it comes to a language like <code>C</code>. <code>C</code> is an old language and the developers may have not thought about the issues and discomfort. But in case of modern languages like java, they still had a chance to redefine the design. Why have they chosen to keep it the same?</p>
<p>Is it somehow related to working of operating systems or did they actually wanted to continue with the familiar behaviour or design structure (though new programmers face a lot of problems related to this)?</p>

35,947,602 | how can I store a variable(Int) permanently after app closes and Display it? | I am trying to store a variable named *total* which holds the number of rows in UItableView. Since the user types strings for UITableView, the variable is *listTable* which is String array.
I have my *total* as total = listTable.count
ISSUE:
Every time the app launches it displays 0 as number of rows used, however once you go to the UITableView ViewController and come back to the main ViewController it automatically corrects its self to the current amount of rows.
Code Used:
import UIKit
var listTable = [String]()
var total = listTable.count
class ViewController: UIViewController, UITextFieldDelegate {
@IBOutlet weak var numberOfRows: UILabel!
@IBOutlet weak var TypeToCreateRow: UITextField!
@IBOutlet weak var AddRow: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
total = listTable.count
NSUserDefaults.standardUserDefaults().setObject(total, forKey: "rows")
let showRow = NSUserDefaults.standardUserDefaults().objectForKey("rows")!
numberOfRows.text = "\(showRow)"
print(showRow)
// Do any additional setup after loading the view, typically from a nib.
}
@IBAction func RowAdd(sender: UIButton) {
listTable.append(TypeToCreateRow.text!)
TypeToCreateRow.text = " "
numberOfRows.text = "\(total)" }

<p>Looking around, I read about similar issues regarding bad scaling or incorrect preview in Android Studio. Well, my problem is unluckily different.</p>
<p>PROBLEM:</p>
<p>In fact, my VectorDrawable renders perfectly in the Android Studio preview but gets messed up at runtime on device (Android v. 5.1.1 and 6.0).</p>
<p>EXPORTING:</p>
<p>Starting from an SVG file (with only one compounded path), I imported it with the Android Studio tool (but I also tried many other tools to convert it).
The file was made in the same way as a bunch of others, though only some render bad.</p>
<p>WHAT I ALREADY TRIED:</p>
<p>I tried to set it in an imageview with app:srcCompat (even with src:).
I tried to use it in a menu (directly setting the icon, or using a
selector).</p>

<p>I can't really figure out what's causing the bad rendering. I'm pretty sure it's not an svg problem (correct me if I'm wrong, please) since the other drawables are rendering correctly. I wouldn't even call for a library bug since I happen to be the only one experiencing the problem. What am I doing wrong?</p>

35,949,554 | Invoking a function without parentheses | <p>I was told today that it's possible to invoke a function without parentheses. The only ways I could think of was using functions like <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply"><code>apply</code></a> or <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call"><code>call</code></a>.</p>
<pre><code>f.apply(this);
f.call(this);
</code></pre>
<p>But these require parentheses on <code>apply</code> and <code>call</code> leaving us at square one. I also considered the idea of passing the function to some sort of event handler such as <a href="https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout"><code>setTimeout</code></a>:</p>
<pre><code>setTimeout(f, 500);

35,950,211 | bash script to search directory only specific file types | <p>I'm trying to write a bash script that will search a folder for specific file extensions (lets say .txt and .csv). The folder can have thousands of each type of extension. If the folder has only these two extensions across all files then the script can proceed. If any other extensions are present (and the two allowed extesions may also be preset), the script copies the folder to a holding bucket and writes to a log file.
The folder that is being searched will never have subfolders.</p>
<p>So, if the folder has:
.txt and .csv, this passes
If the folder has:
.mp3, this fails
If the folder has:
.txt, .csv and .mp3, this also fails.</p>

35,950,393 | ports for openvpn and websockets | <p>this will sound a silly question....
but id like to know the following.
i was going to install a freeswitch voip server on small intel nuc and on another intel nuc (nucs are small low powered desktop like units ) i planned to install openvpn to be used as a very useful vpn for when im on a dodgy wifi connection.</p>
<p>since id like openvpn to be running on port 443 tcp and since freeswitch ideally runs on 443 tcp i figured id need two seperate computers - hence the two machines on 2 completely different remote internet connections .</p>
<p>however im rather inclined to install both openvpn port 443 tcp ( running all the time) and also freeswitch websocket server ( listening on 443 tcp) running on the same computer and behind one router on a friends broadband connection port forwarding anything coming in for 443 tcp to the same local ip add of the same server running both freeswitch websocket and openvpn - is this a good idea?</p>
<p>id sooner not change the listening port on openvpn - since the default 1194 may well be blocked from hotel wifi etc and web sockets will undoubtedly respond more reliably if its listening on 443 tcp.</p>
<p>can two services listening on the same port / protocol work ok (nat wise )behind the router ?</p>

35,952,538 | How can I disable or hide the scrollbar within an Ionic 2 <ion-content> | <p>I have an Angular 2 app wrapped in Ionic 2. I'm using <code><ion-tabs></code>, and within each tab is an <code><ion-content></code>. The content in this area needs to be scrollable, but Ionic 2 adds a scrollbar that I don't want displayed. It appears that, when compiled, an <code><ion-content></code> has a <code><scroll-content></code> injected into it. I don't want this behavior. </p>
<p>I have tried many of the solutions that <em>used to</em> work in Ionic 1, but they do not work in Ionic 2:</p>
<ul>
<li>Setting <code>scroll="false"</code> on the <code><ion-content></code></li>
<li>Setting <code>scrollbar-y="false"</code> on the <code><ion-content></code></li>
<li>Setting <code>overflow-scroll="false"</code> on the <code><ion-content></code></li>
<li><p>Setting the following in css:</p>
<p><code>.scroll-bar-indicator
{
display: none;
}</code></p></li>
</ul>
<p>etc...</p>
<p>Setting the following actually does work to remove the scrollbar, but I'd rather not hijack the browser behavior, and also it removes scrollbars from content internal to the <code><ion-content></code> tag, which I don't want. </p>
<pre><code>::-webkit-scrollbar,
*::-webkit-scrollbar {

35,953,394 | Calculating length of 95%-CI using dplyr | <p>Last time I asked how it was possible to calculate the average score per measurement occasion (week) for a variable (procras) that has been measured repeatedly for multiple respondents. So my (simplified) dataset in long format looks for example like the following (here two students, and 5 time points, no grouping variable):</p>
<pre><code>studentID week procras
1 0 1.4
1 6 1.2
1 16 1.6
1 28 NA
1 40 3.8
2 0 1.4
2 6 1.8
2 16 2.0
2 28 2.5
2 40 2.8
</code></pre>
<p>Using dplyr I would get the average score per measurement occasion</p>
<pre><code>mean_data <- group_by(DataRlong, week)%>% summarise(procras = mean(procras, na.rm = TRUE))
</code></pre>
<p>Looking like this e.g.:</p>
<pre><code>Source: local data frame [5 x 2]
occ procras
(dbl) (dbl)
1 0 1.993141
2 6 2.124020
3 16 2.251548
4 28 2.469658
5 40 2.617903
</code></pre>
<p>With ggplot2 I could now plot the average change over time, and by easily adjusting the group_data() of dplyr I could also get means per sub groups (for instance, the average score per occasion for men and women).
Now I would like to add a column to the mean_data table which includes the length for the 95%-CIs around the average score per occasion.</p>
<p><a href="http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/" rel="noreferrer">http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/</a> explains how to get and plot CIs, but this approach seems to become problematic as soon as I wanted to do this for any subgroup, right? So is there a way to let dplyr also include the CI (based on group size, ect.) automatically in the mean_data?
After that it should be fairly easy to plot the new values as CIs into the graphs I hope.
Thank you.</p>

<li>For every multiplication that results a number more than 9, add them digits. (For example, from the calculation on (no.2) we will get this :
<code>(6)+(4)+(16)+(5)</code>. So we got a number (16) which is more that 9. We need to add them <code>(1+6=7)</code>. Now the output will be like this : <code>(6)+(4)+(7)+(5)</code>.</li>
<li>Next, we add them <code>(6)+(4)+(7)+(5)=22</code></li>

35,955,946 | My C code is kinda drunk | I'm so confused here... why this code of mine doesn't work as it SHOULD be..
Here's the code:
void print(int x) {
x = 140;
int i,total, length, XLength;
if (x < 10){XLength = 0;}
else {
int sum = 1;
for (i = 0 ; i < 10 ; i++){
total = 10 * sum; sum = total; length = x / total;
if (length < 10 && 1 <= length){ XLength = i+1; break;}
}}
XLength = pow(10,XLength);
printf("%d\n",XLength);
}
Let me explain how the code should works first: It takes an integer x and print out the highest power of 10 value it can be divided by.
So if X = 80, it should print 10 and if x = 12435, it should print 10000.
But... this doesn't work with my code perfectly... if x = 140, it prints 99 but.. if x = 1400, it prints 1000.. then again, if x = 14000 it prints 9999 and if x = 140000 it prints 100000 and the sequence continues...
I've already tried exactly the same code in Java and it works perfectly!!
Why does it not works in C??

35,957,463 | Creating a Behavior for a continuously measurable phenomenon | <p>I would like to create a <code>Behavior t a</code> from an <code>IO a</code>, with the intended semantics that the IO action would be run every time the behavior is <code>sample</code>d:</p>
<pre><code>{- language FlexibleContexts #-}
import Reflex.Dom
import Control.Monad.Trans
onDemand :: (MonadWidget t m, MonadIO (PullM t)) => IO a -> m (Behavior t a)
</code></pre>
<p>I hoped I could do this by just executing the <code>measurement</code> in a <code>pull</code>:</p>
<pre><code>onDemand measure = return $ pull (liftIO measure)
</code></pre>
<p>However, the resulting <code>Behavior</code> never changes after an initial <code>measure</code>ment.</p>
<p>The workaround I could come up with was to create a dummy <code>Behavior</code> that changes "frequently enough" and then create a fake dependency on that:</p>
<pre><code>import Data.Time.Clock as Time
hold_ :: (MonadHold t m, Reflex t) => Event t a -> m (Behavior t ())
hold_ = hold () . (() <$)
onDemand :: (MonadWidget t m, MonadIO (PullM t)) => IO a -> m (Behavior t a)
onDemand measure = do
now <- liftIO Time.getCurrentTime
tick <- hold_ =<< tickLossy (1/1200) now
return $ pull $ do
_ <- sample tick
liftIO measure
</code></pre>
<p>This then works as expected; but since <code>Behavior</code>s can only be sampled on demand anyway, this shouldn't be necessary. </p>
<p>What is the correct way to create a <code>Behavior</code> for a continuous, observable-at-any-time phenomenon?</p>

35,957,842 | Working with Logical And and multiple return values Ruby | I'm trying to check multiple conditions in a function.
So i have written following code
def validate
value,message = check_length(name) && is_valid(id)
end
check_length and is_valid returns 2 values. so i store these values in value and message.
Now if check_length returns value as false, it shouldn't evaluate second method is_valid. Ideally with logical and, if first condition fails, it doesn't execute other method. But for above code even if check_length returns value as false, it evaluates is_valid and value is overridden by return value of is_valid.
How can we break if first condition value is false and return from validate function?

I've already made a program that does it but I just recently found at that we need to use procedures and functions, this is what I've done so far.So what i want to do is take 1/3 of the value of outputgrade and add it with 2/3 of the value of outputgrade2, I tried midterm1=(outputgrade()*1/3)+(outputgrade2*2/3) but I receive an error which is "Not an allowed type". Please somebody help me on what to do.

35,962,372 | Return pointer to a structure - C | i have this program, where you enter two dates into two structures (same type), and then I want a function to find which date i entered is the later date. It compares only year and month. Once the later date is found, i want the function to return a pointer to the structure with the later date. I then want to print out the later date.

35,962,754 | GIT: How can I prevent foxtrot merges in my 'master' branch? | <p>A foxtrot merge is a merge where 'origin/master' merges in as a 2nd (or later) parent, like so:</p>
<p><a href="https://i.stack.imgur.com/yZMCS.png"><img src="https://i.stack.imgur.com/yZMCS.png" alt="Commit 'D' is a foxtrot merge because 'origin/master' is its 2nd parent."></a></p>
<p><sup><i>Commit 'D' is a foxtrot merge because 'origin/master' is its 2nd parent. Notice how first-parent history from 'origin/master' contains commit 'B' at this moment. </i></sup></p>
<p>But in my git repo I need all merges involving 'origin/master' to keep 'origin/master' as the 1st parent. Unfortunately git doesn't care about parent-order when it evaluates whether a commit is eligible for fast-forward. This causes the first parent history on my master branch to sometimes lose commits that used to be there (e.g., output of "git log --first-parent").</p>
<p>Here's what happens when commit 'D' from the earlier diagram is pushed:</p>
<p><a href="https://i.stack.imgur.com/ACgpr.png"><img src="https://i.stack.imgur.com/ACgpr.png" alt="How can I prevent this push? First-parent history of 'origin/master' no longer contains commit 'B' after the foxtrot merge is pushed!"></a></p>
<p><sup><i>How can I prevent this push? First-parent history of 'origin/master' no longer contains commit 'B' after the foxtrot merge is pushed!</i></sup></p>
<p>Obviously no commits or work are actually lost, it's just that in my environment I really need "git log --first-parent" to be a stable accumulative record of commits - if you like, a kind of "Write-Once Read-Many" (WORM) database. I have scripts and processes that use "git log --first-parent" to generate changelogs and release notes, as well as to manage ticket transitions in my ticketing system (JIRA). Foxtrot merges are breaking my scripts!</p>
<p>Is there some kind of pre-receive hook I could install in my git repositories to prevent foxtrot merges from getting pushed?</p>

Take under consideration `clear: both;` to start new line.** Vertical alignment woudl be nice but is not necessity. Number of words (lines) and letters vary depeneding on situation.
All the guides i have found about centering tell about centering multiple divs but they are in one line or are centered after free break line (there is no space for next div in line so it takes next line with remaining divs and center the line).
