C(++) How is argv a string array when its a char array : Why doesnt argv[0] print the first character of the filename instead of the whole filename string?
If argv is a pointer to an array of chars, then shouldnt accessing it with [n] result with a char? If its a string (as printf(argv[n]) suggests) then why doesnt argv[0][0] get me the first char of filename (compiles but crashes when started)? | 0debug |

Why android ListView displays only one row? : I have custom adapter for ListView. No matter how many items are passed to it it displays only one row.
I verified by debugging that overrided methods return correct result. For example getCount() returns: 3, getView(2, null, (ListView)rootView) returns expected view with TextView holding item name.
Anyone can help? | 0debug |

Reading response headers with Fetch API : <p>I'm in a Google Chrome extension with permissions for <code>"*://*/*"</code> and I'm trying to make the switch from XMLHttpRequest to the <a href="https://developers.google.com/web/updates/2015/03/introduction-to-fetch" rel="noreferrer">Fetch API</a>.</p>
<p>The extension stores user-input login data that used to be put directly into the XHR's open() call for HTTP Auth, but under Fetch can no longer be used directly as a parameter. For HTTP Basic Auth, circumventing this limitation is trivial, as you can manually set an Authorization header:</p>
<pre><code>fetch(url, {
headers: new Headers({ 'Authorization': 'Basic ' + btoa(login + ':' + pass) })
} });
</code></pre>
<p><a href="https://en.wikipedia.org/wiki/Digest_access_authentication#Example_with_explanation" rel="noreferrer">HTTP Digest Auth</a> however requires more interactivity; you need to read parameters that the server sends you with its 401 response to craft a valid authorization token. I've tried reading the <code>WWW-Authenticate</code> response header field with this snippet:</p>
<pre><code>fetch(url).then(function(resp) {
resp.headers.forEach(function(val, key) { console.log(key + ' -> ' + val); });
}
</code></pre>
<p>But all I get is this output:</p>
<pre><code>content-type -> text/html; charset=iso-8859-1
</code></pre>
<p>Which by itself is correct, but that's still missing around 6 more fields according to Chrome's Developer Tools. If I use <code>resp.headers.get("WWW-Authenticate")</code> (or any of the other fields for that matter), i get only <code>null</code>.</p>
<p>Any chance of getting to those other fields using the Fetch API?</p>

Need help making while loops work : I've always struggled with while loops because they barely ever work for me. They always crash my programs but in this instance I really need it to work:
void Update () {
while (!gameOver)
{
if (!spawned)
{
//Do something
}
else if (timer >= 2.0f)
{
//Do something else
}
else
{
timer += Time.deltaTime;
}
}
}
Ideally, I want those if statements to run as the game runs. Right now it crashes the program and I know it's the while loop which is the problem because it crashes anytime I comment it out. | 0debug |

why the output is not logic ? :
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
let vacationSpots = ['USA', 'UK', 'Colombia'];
for (let vacationSpotIndex = vacationSpots.length - 1; vacationSpotIndex >= 0; vacationSpotIndex-- ) {
console.log('I would love to visit ' + vacationSpots[vacationSpotIndex]);
}
<!-- end snippet -->
i suppose the lenght is 3 and we substract 1 so it equals to 2;
so the index start is 2 and we substract 1 on every loop
the probleme in the condition
vacationSpotIndex >= 0
i suppose logicly it is vacationSpotIndex <= 0

Convert date to "dd.MM.yyyy" format date in swift : I work with an API, where one of parameters is of type Date in format "dd.MM.yyyy".
I cant manage to convert it. I created an extension for Date, where I tried to implement it in next way:
extension Date {
var shortDate: Date {
let formatter = DateFormatter()
formatter.dateFormat = "dd.MM.yyyy"
let strDate = formatter.string(from: self)
let modifiedDate = formatter.date(from: strDate)
return modifiedDate!
}
}
and I call it like that:
let day = Date().shortDate
but unfortunately it doesn't work and it looks like that:

Failed to refresh gradle project in IntelliJ IDEA 2016.1: Unknown method ScalaCompileOptions.getForce() : <p>I have a Gradle-based project primarily with Java code and a small subproject with Scala (a Gatling-based performance test).</p>
<p>I recently upgraded Gradle wrapper to v2.12, which is currently the latest version.
And today I just updated IntelliJ Idea from v15 to v2016.1.</p>
<p>When I try to refresh the project from the Gradle files in Idea, I get this error.</p>
<pre><code>Error:Cause: org.gradle.api.tasks.scala.ScalaCompileOptions.getForce()Ljava/lang/String;
</code></pre>
<p>I noticed when searching on Google, that the method getForce() (returning a String) apparently has been replaced by isForce() (returning a boolean).</p>
<p>If i downgrade Gradle wrapper to v2.11 the problem disappears.
Is there anything else I can do to fix the problem?</p>

Compare multiple lists inside a list Python : <p>Is it possible to compare a list containing an unknown number of lists with equal elements in a more terse (aka shorter) manner than what I have done? Preferably an one-liner!</p>
<p>Here's an example if it's unclear what I want to do:</p>
<pre><code>a = [1, 2, 3]
b = [4, 2, 1]
c = [7, 5, 1]
d = [a, b, c]
def multiCompList(lists):
final = [i for i in lists[0] if i in lists[1]]
for i in range(2, len(lists)):
final = [i for i in final if i in lists[i]]
return final
print(multiCompList(d))
</code></pre>
<p>What I've done is to first check if the first and second list contains any equal elements and put them in a list called final. Thereafter, checking if those elements can be found in the lists after and replacing the final-list with the remaining equal elements.
The results in this case is: [1].</p>

Go channels only sending values : I am learning channels in GO and following this [tutorial][1]
When I only send value to a channel it gives error. Here is the example code.
package main
import "fmt"
func main() {
ch := make(chan int)
ch <- 1
fmt.Println("Does not work")
}
Here I am just sending value to the channel but not receiving anything. It give an error
fatal error: all goroutines are asleep - deadlock!
But when I run following code it doesn't give any error
package main
import "fmt"
func sum(s []int, c chan int) {
sum := 0
for _, v := range s {
sum += v
}
c <- sum // send sum to c
}
func main() {
s := []int{7, 2, 8, -9, 4, 0}
c := make(chan int)
go sum(s[:len(s)/2], c)
go sum(s[len(s)/2:], c)
fmt.Println("did not receive but still works")
}
and prints
did not receive but still works
I couldn't understand why it works in second case while it does not work in first case. Even though I have not received any value for the channel in both cases. Also what is causing the deadlock in first case and how it gets avoided in second case?

R, _ := strconv.Atoi(reader.ReadString(" "))
And the problem is, that strconv.Atoi expects one argument, but reader.ReadString() returns not only the string, but also the "err". Is there a way to solve this without creating variables or generally on just one line? | 0debug |
How to check if integer comes null/empty : I need to check if an input comes null/empty.
If input <= 100 And input > 0 And Not input = "" Then
subjectsInt.Add(subjects(i), input)
check = True
End If
I know in that code I am checking it as String but I already did `Not input = Nothing` and `Not input = 0` and I am getting an error:
>Run-time exception (line -1): Conversion from string "" to type 'Integer' is not valid.
>Stack Trace:
>[System.FormatException: Input string was not in a correct format.]
>[System.InvalidCastException: Conversion from string "" to type 'Integer' is not valid.]
Any suggestions? | 0debug |

Physics vector constructor, magnitude and unit vector functions not working c++ : <p>I am writing a class called Vector which represents a 3-dimensional vector. I need a constructor which can take a pre-existing Vector object and create a new one from it. This is the constructor:</p>
<pre><code>Vector::Vector(const Vector &v1){
for(int i = 0; i < d; i++)
components[i] = v1.components[i];
}
</code></pre>
<p>This is the note the compiler gives me:</p>
<pre><code>candidate constructor not viable: no known conversion from 'Vector *'
to 'const Vector &' for 1st argument; dereference the argument with *
Vector::Vector(const Vector &v1){
</code></pre>
<p>I also have a magnitude function:</p>
<pre><code>double Vector::magnitude(){
return std::pow(dot(this, this), 0.5);
}
</code></pre>
<p>I come from java so by the use of this I mean to say use this instance of the class and pass it in as a Vector to the dot function. I get the following error:</p>
<pre><code>error: no viable conversion from 'Vector *' to 'Vector'
return std::pow(dot(this, this), 0.5);
</code></pre>
<p>I also have a unit vector function where I try to use my constructor above to create a copy of the Vector object using <code>this</code>.</p>
<pre><code>Vector Vector::getUnitVector(){
Vector unit(this);
unit.scale(1/unit.magnitude());
return unit;
}
</code></pre>
<p>I get the following error:</p>
<pre><code>error: no matching constructor for initialization of 'Vector'
Vector unit(this);
</code></pre>
<p>How can I fix these errors? Thank you.</p>

Key Commands must all have a Title, Key and Selector : <p>I am receiving and error when trying to build, Xcode 8.0 Beta 4, and when I'm building it says "error: Illegal Configuration: Key Commands must all have a Title, Key, and Selector. Select each row in the table to check its configuration."</p>
<p>It isn't on a TableView or anything, its a UIView with a Stack View inside it and some buttons, thats about it.</p>
<p>And this is on a Storyboard file I'm getting the error</p>
<p>I can't figure out what that might be?</p>

IntelliSense for Razor Pages routes : <p>I was toying with new Razor Pages in ASP .NET Core 2.0 and noticed some problems with IntelliSense.</p>
<p>When using tag helper for MVC controller I get usual help:</p>
<p><a href="https://i.stack.imgur.com/cH6j6.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cH6j6.png" alt="MVC with IntelliSense"></a></p>
<p>However there is no such help for <code>asp-page</code> tag helper used in Razor Pages:</p>
<p><a href="https://i.stack.imgur.com/k8Ooi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/k8Ooi.png" alt="razor Pages with no help"></a></p>
<p>Is this a problem with my Visual Studio or rather Razor Pages tags do not support it yet?</p>
<p>I use ASP .NET Core 2.0 with framework 4.7 on VS 2017 15.5.5.</p>

Difference between routing inside v-btn and using router-link : <p>I am learning Vue.js, and, following a tutorial, a is used to route the page to another. He used a button wrapped by this tag, and I found that using the routing directive inside the tag.
I was wondering, what's the difference between this two ways of going from one page to another? Both of them seems to be producing the same behavior (and I am not sending or receiving any data when changing pages).</p>
<p>Codes for comparison:</p>
<p>Using <strong>v-btn</strong></p>
<pre><code><v-btn :to="{name: 'songs-create'}"
dark medium right bottom fab absolute
class="pink" slot="action">
<v-icon>add</v-icon>
</v-btn>
</code></pre>
<p>Using <strong>router-link</strong></p>
<pre><code><router-link :to="{name: 'Hello'}" tag="span" class="logo">Tab Tracker</router-link>
</code></pre>
<p>Thanks in advance!</p>

<pre><code>import requests

The ability to fight with Ad-Blocker : <p>I had searched by google and this forum-search and I didnt get any about this so I propose a new topic: WordPress with the ability to fight with Ad-Blocker.</p>
<p>I am not an IT guy (subsea engineer) but I am having <a href="http://interresults2015.in/" rel="nofollow">website</a> with about 100 - 200 unique visitor/day now (according to adsense) as hobby (1%-4% using ad-blocker - I am lucky to have these ~97% my visitors).</p>
<p>I just learn that ad-block users are about 300 mil and it is a huge problem to big publisher (they earn money from ads). Ad-blocker using bandwith, upload data to their server and some (one of them - I expect more of them) sell the data as anons.</p>
<p>In accordance to the above idea,
I have a question as a-non IT guys, is there a way to make WordPress to tackle ad-blocker (auto)?</p>
<p>It may be a way to disarm ad-blocker. My website is like my home/house. You/Visitors can visit but please consider the owner.</p>

Swift: How do I safe the value for variable? : so here is a brief explanation of my code:
var myVar = 0
if(button image is equal to "mybutton image") {
myVar = 1
print("It works")
} else {
myVar = 2
print("Not working")
}
ButtonPress {
print(myVar)
}
The problem here is that when I run the application I see in the console that it prints "it works" but when I press the button myVar is equal to 0 again so how do I make sure when I press the button myVar will be equal to 1?
Thank you!

Find most efficient groups of pairs : <h2>Problem</h2>
<p>I have a group of people, and I want each person to have a 1:1 meeting with every other person in the group. A given person can only meet with one other person at a time, so I want to do the following:</p>
<ol>
<li>Find every possible pairing combination</li>
<li>Group pairs together into "rounds" of meetings, where each person can only be in a round once, and where a round should contain as many pairs as possible to satisfy all possible pairing combinations in the smallest number of rounds.</li>
</ol>
<p>To demonstrate the problem in terms of desired input/output, let's say I have the following list:</p>
<pre><code>>>> people = ['Dave', 'Mary', 'Susan', 'John']
</code></pre>
<p>I want to produce the following output:</p>
<pre><code>>>> for round in make_rounds(people):
>>> print(round)
[('Dave', 'Mary'), ('Susan', 'John')]
[('Dave', 'Susan'), ('Mary', 'John')]
[('Dave', 'John'), ('Mary', 'Susan')]
</code></pre>
<p>If I had an odd number of people, then I would expect this result:</p>
<pre><code>>>> people = ['Dave', 'Mary', 'Susan']
>>> for round in make_rounds(people):
>>> print(round)
[('Dave', 'Mary')]
[('Dave', 'Susan')]
[('Mary', 'Susan')]
</code></pre>
<p>The key to this problem is that I need my solution to be performant (within reason). I've written code that <em>works</em>, but as the size of <code>people</code> grows it becomes exponentially slow. I don't know enough about writing performant algorithms to know whether my code is inefficient, or whether I'm simply bound by the parameters of the problem</p>
<h2>What I've tried</h2>
<p>Step 1 is easy: I can get all possible pairings using <code>itertools.combinations</code>:</p>
<pre><code>>>> from itertools import combinations
>>> people_pairs = set(combinations(people, 2))
>>> print(people_pairs)
{('Dave', 'Mary'), ('Dave', 'Susan'), ('Dave', 'John'), ('Mary', 'Susan'), ('Mary', 'John'), ('Susan', 'John')}
</code></pre>
<p>To work out the rounds themselves, I'm building a round like so:</p>
<ol>
<li>Create an empty <code>round</code> list</li>
<li>Iterate over a copy of the <code>people_pairs</code> set calculated using the <code>combinations</code> method above</li>
<li>For each person in the pair, check if there are any existing pairings inside the current <code>round</code> that already contain that individual</li>
<li>If there's already a pair that contains one of the individuals, skip that pairing for this round. If not, add the pair to the round, and remove the pair from the <code>people_pairs</code> list.</li>
<li>Once all the people pairs have been iterated over, append the round to a master <code>rounds</code> list</li>
<li>Start again, since <code>people_pairs</code> now contains only the pairs that didn't make it into the first round</li>
</ol>
<p>Eventually this produces the desired result, and whittles down my people pairs until there are none left and all the rounds are calculated. I can already see that this is requiring a ridiculous number of iterations, but I don't know a better way of doing this.</p>
<p>Here's my code:</p>
<pre><code>from itertools import combinations
# test if person already exists in any pairing inside a round of pairs
def person_in_round(person, round):
is_in_round = any(person in pair for pair in round)
return is_in_round
def make_rounds(people):
people_pairs = set(combinations(people, 2))
# we will remove pairings from people_pairs whilst we build rounds, so loop as long as people_pairs is not empty
while people_pairs:
round = []
# make a copy of the current state of people_pairs to iterate over safely
for pair in set(people_pairs):
if not person_in_round(pair[0], round) and not person_in_round(pair[1], round):
round.append(pair)
people_pairs.remove(pair)
yield round
</code></pre>
<p>Plotting out the performance of this method for list sizes of 100-300 using <a href="https://mycurvefit.com" rel="noreferrer">https://mycurvefit.com</a> shows that calculating rounds for a list of 1000 people would probably take around 100 minutes. Is there a more efficient way of doing this?</p>
<p>Note: I'm not <em>actually</em> trying to organise a meeting of 1000 people :) this is just a simple example that represents the matching / combinatorics problem I'm trying to solve. </p>

MongoDB Print Pretty with PyMongo : <p>I've looked up print pretty for MongoDB, and i understand how to do it from the shell. What I can't find is how to do it with PyMongo, so that when I run it in eclipse, the output will print pretty instead of all in one line. Here's what I have right now:</p>
<pre><code> cursor = collection.find({})
for document in cursor: print(document)
</code></pre>
<p>This prints everything in my collection, but each document in my collection just prints in one line. How can i change this to get it to print pretty?</p>

Navigator.mediaDevices.getUserMedia not working on iOS 12 Safari : <p>As of iOS 12, <code>navigator.mediaDevices.getUserMedia()</code> is returning an error in Safari.</p>
<p>To recreate this, open <a href="https://developer.apple.com/library/archive/documentation/AppleApplications/Conceptual/Safari_Developer_Guide/GettingStarted/GettingStarted.html" rel="noreferrer">iPhone Web Inspector</a>, then run this snippet in the console:</p>
<pre><code>var constraints = { audio: true, video: { width: 1280, height: 720 } };
navigator.mediaDevices.getUserMedia(constraints)
.then(function() {
console.log('getUserMedia completed successfully.');
})
.catch(function(error) {
console.log(error.name + ": " + error.message);
});
</code></pre>
<p>You'll see that this runs successfully in desktop browsers, and in iOS 11 Safari, but fails in iOS 12 Safari.</p>
<blockquote>
<p>NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.</p>

<p>Any idea why?</p>
<p><em>note: This is happening prior to the user being asked if their camera can be accessed, ruling out the possibility of it being because the user denied permission.</em></p>

What is the purpose for the fallback option in ExtractTextPlugin.extract : <p>Using the example from <a href="https://github.com/webpack-contrib/extract-text-webpack-plugin" rel="noreferrer">webpack-contrib/extract-text-webpack-plugin</a>:</p>
<pre><code>const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
module: {
rules: [
{
test: /\.scss$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
//resolve-url-loader may be chained before sass-loader if necessary
use: ['css-loader', 'sass-loader']
})
}
]
},
plugins: [
new ExtractTextPlugin('style.css')
//if you want to pass in options, you can do so:
//new ExtractTextPlugin({
// filename: 'style.css'
//})
]
}
</code></pre>
<p>What is the purpose of the fallback option?</p>
<p>How I see this snippet to work is: </p>
<p>I instruct webpack to use the <code>ExtractTextPlugin</code> on every <code>.scss</code> file it encounter. I am telling <code>ExtractTextPlugin</code> to use <code>['css-loader', 'sass-loader']</code> loaders to generate the css. Webpack will then emit extra <code>style.css</code> file containing the css.</p>
<p>I can then reference this file in my index.html or if I am using html-webpack-plugin it will be added automatically to it.</p>
<p>I can remove the <code>fallback: 'style-loader',</code> option and everything continues to work.</p>
<p>What does it mean to fallback to <code>style-loader</code>?</p>
<p>How/When the fallback gets triggered?</p>
<p>I understand what <code>style-loader</code> is doing and how it is modifying the DOM with style tag if I am not using the <code>ExtractTextPlugin</code>. I just can't understand the fallback option when I am using <code>ExtractTextPlugin</code>.</p>

JavaScript Event Listeners inside methods : <p>I was hoping to be able to call object methods from an event listener, however, I am unable to access object properties on the called function:</p>
<pre><code>import {action} from '../desktopIntegration/actions.js'
class Object {
constructor() {
this.property = 2
}
addListener() {
action.on("keyup", this.printEvent)
}
printEvent() {
console.log(this.property)
}
}
</code></pre>
<p>This code gives the error:</p>
<pre><code> unable to access property of undefined
</code></pre>
<p>when addListener is called.</p>
<p>Is there a way to make this work? I want to keep the callback as a method function so that I can delete the listener on each instance of Object. </p>
<p>Thanks!</p>
