Is this a valid way of checking if a variadic macro argument list is empty? : <p>I've been looking for a way to check if a variadic macro argument list is empty. All solutions I find seem to be either quite complex or using non-standard extensions. </p>
<p>I think I've found an easy solution that is both compact and standard:</p>
<pre><code>#define is_empty(...) ( sizeof( (char[]){#__VA_ARGS__} ) == 1 )
</code></pre>
<p>Q: Are there any circumstances where my solution will fail or invoke poorly-defined behavior?</p>
<p>Based on C17 6.10.3.2/2 (the # operator): <em>"The character string literal corresponding to an empty argument is <code>""</code>"</em>, I believe that <code>#__VA_ARGS__</code> is always well-defined. </p>
<p>Explanation of the macro:</p>
<ul>
<li>This creates a compound literal char array and initializes it by using a string literal.</li>
<li>No matter what is passed to the macro, all arguments will be translated to one long string literal. </li>
<li>In case the macro list is empty, the string literal will become <code>""</code>, which consists only of a null terminator and therefore has size 1. </li>
<li>In all other cases, it will have a size greater than 1.</li>
</ul>

Difference between generators and functions returning generators : <p>I was debugging some code with generators and came to this question. Assume I have a generator function</p>
<pre><code>def f(x):
yield x
</code></pre>
<p>and a function returning a generator:</p>
<pre><code>def g(x):
return f(x)
</code></pre>
<p>They surely return the same thing. Can there be any differences when using them interchangeably in Python code? Is there any way to distinguish the two (without <code>inspect</code>)?</p>

Angular 2 - communication of typescript functions with external js libraries : <p>Using <a href="https://philogb.github.io/jit/" rel="noreferrer">Javascript Infovis Toolkit</a> as an external library for drawing graph and trees. I need to manipulate the onClick method of nodes in order to asynchronously sending an HTTP GET request to the server and assign the data that comes from server to the properties and variables of an Angular service class. By Using webpack for packing all the compiled typescripts to a single js file, the output file is confusing and unreadable. so calling a function which is in the compiled js file from an external js library, is not the best solution clearly.</p>
<p>I try the following solution inside my Angular service so I can access to the properties of this service without any trouble:</p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>document.addEventListener('DOMContentLoaded', function () {
var nodes = document.querySelectorAll(".nodes"); // nodes = []
for (var i = 0; i < nodes.length; i++) { // nodes.length = 0
nodes[i].addEventListener("click", function () {
// asynchronously sending GET request to the server
// and assing receiving data to the properties of this Angular service
});
}
});</code></pre>
</div>
</div>
</p>
<p>However, this solution doesn't work because in Javascript Infovis Toolkit the nodes are drawn after finishing rendering of DOM and also after <code>window.onload</code> event. This library has some lifecycle methods such as onAfterCompute() which is called after drawing tree is completed. How can I trigger a global event to inform the Angular service that the drawing of tree is completed and it can query all of the nodes?</p>

get the value of a point by interpolation in R : <p>I need to get the value of temperature in a point (latitude, longitude) using the value of temperature of others points (latitude, longitude) by interpolation... I have the temperature of some stations (for exemple, 10, 40.01, 03.00 ....) in a csv file.
I want to use only the values inside a radio from my point. How can I do that in R?</p>

Why does closing a channel in defer statement panics? : In the following example, a go routine is pumping values into unbuffered channel and the main function is iterating over it.
```go
package main
import (
"fmt"
"strconv"
)
var chanStr chan string
func main() {
go pump()
fmt.Println("iterating ...")
for val := range chanStr {
fmt.Printf("fetched val: %s from channel\n", val)
}
}
func pump() {
defer close(chanStr)
chanStr = make(chan string)
for i := 1; i <= 5; i++ {
fmt.Printf("pumping seq %d into channel\n", i)
chanStr <- "val" + strconv.Itoa(i)
}
//close(chanStr)
}
```
The function panics with the following output:
```
iterating ...
pumping seq 1 into channel
pumping seq 2 into channel
fetched val: val1 from channel
......
fetched val: val4 from channel
pumping seq 5 into channel
panic: close of nil channel
goroutine 5 [running]:
main.pump()
C:/personal/gospace/go-rules/test.go:26 +0x1a6
created by main.main
C:/personal/gospace/go-rules/test.go:11 +0x4e
```
However if I comment the defer statement and close right after the for loop in the goroutine `pump` , the receiver doesn't panic.
*What's the difference in both the cases?* Looks like defer closes the channel before the value is received but the regular close waits.
Also when I built using the race detector on, even in the regular close it flags a potential race condition (I'm not able recreate the race every time). Does it imply that both of those ways are not right in gracefully closing the channel?

HTML horizonal aligment : I have a div in which theres an image and an text.
<div class="logo">

Right now, the logo is above the text. I want that the logo would be on left and text on right but close to each other, so I can add something else on the far side of left page.

android studio 2: Capture latitude and longitude : i know this question is repeated question, but i didn't find a clear overview. I am using Studio 2.1 and I need below information.
I am developing a app, which capture the latitude and logitude from one mobile and send those details to Master/Server Mobile, So that server mobile will show the tracking maps on server mobile.
Here i need an over all process.
1. I developed a background code in client mobile
After 1st step, i am confused how to move further. Do i need to create any website and capture the latitude and longitude.
OR
Do i need to follow any other steps.
Please guide me only on higher level steps.

Best way to check for null values using *ngFor in Angular 2 : <p>I'm showing some records coming from an <code>api</code> and some of the results are null and I would like to show a different value in case the response values are null. How would be the best way to do it?</p>
<p>Below is my code: </p>
<p>Component: </p>
<pre><code>import {Component, OnInit} from '@angular/core';
import {PerformancesService} from '../../services/performances.service';
import {Performance} from '../../common/performance';
@Component({
selector: 'performances',
templateUrl: './app/components/performances/performances.component.html'
})
export class PerformancesComponent implements OnInit{
performances: Performance[];
constructor(private _service : PerformancesService){
}
getFunds(){
this._service.getData().then(
performances => this.performances = performances
)
}
ngOnInit(){
this.getFunds();
}
}
</code></pre>
<p>template: </p>
<pre><code><h2>Performance</h2>
<table class="table table-hover">
<thead>
<tr>
<th>Fund Id</th>
<th>Country Id</th>
<th>1Mth</th>
<th>3Mth</th>
<th>YTD</th>
<th>1Yr</th>
<th>3Yrs</th>
<th>5Yrs</th>
<th>10Yrs</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let performance of performances">
<td>{{performance.id}}</td>
<td>{{performance.country_id}}</td>
<td>{{performance.OneMonthBack}}</td>
<td>{{performance.ThreeMonthsBack}}</td>
<td>{{performance.YearToDate}}</td>
<td>{{performance.OneYearBack}}</td>
<td>{{performance.ThreeYearsBack}}</td>
<td>{{performance.FiveYearsBack}}</td>
<td>{{performance.TenYearsBack}}</td>
</tr>
</tbody>
</table>
</code></pre>
<p>I don't know if I could do it in the template or I should check each value in my component. Any idea?
Thanks!</p>

AWS SSL on EC2 instance without Load Balancer - NodeJS : <p>Is it possible to have an EC2 instance running, listening on <code>port 443</code>, without a <code>load balancer</code>? I'm trying right now in my <code>Node.JS</code> app but it doesn't work when I call the page using <code>https://</code>. However, if I set it to <code>port 80</code> everything works fine with <code>http://</code>. </p>
<p>I had it working earlier with a <code>load balancer</code> and <code>route53</code>, but I don't want to pay $18/mo for an ELB anymore, especially when I only have one server running.</p>

Difference between sprite and texture? : <p>Can you please explain the difference between texture and sprite? When we zoom in a sprite, it appears blurry because it's basically an image. Is it the same for a texture?</p>
<p>I read this comment on the image below online: </p>
<blockquote>
<p>The background layers are textures and not sprites.</p>
</blockquote>

calling specific index to add a function for that index : I have a liquidfloatingactionbutton and the way you add an action is a didselectitematindex function but how can I call certain indexes to add different function to each different index. This is what I have so far but the error I get is "cannot assign to value: 'index' is a 'let' constant".
func liquidFloatingActionButton(_ liquidFloatingActionButton: LiquidFloatingActionButton, didSelectItemAtIndex index: Int) {

Specifying multiple simultaneous output formats in knitr (new) : <p>Can I write a YAML header to produce multiple output formats for an R Markdown file using knitr? I could not reproduce the functionality described in the answer for <a href="https://stackoverflow.com/questions/25078572/specifying-multiple-simultaneous-output-formats-in-knitr">the original question with this title</a>.</p>
<p>This markdown file:</p>
<pre><code>---
title: "Multiple output formats"
output:
pdf_document: default
html_document:
keep_md: yes
---
# This document should be rendered as an html file and as a pdf file
</code></pre>
<p>produces a pdf file but no HTML file.</p>
<p>And this file:</p>
<pre><code>---
title: "Multiple output formats"
output:
html_document:
keep_md: yes
pdf_document: default
---
# This document should be rendered as an html file and as a pdf file
</code></pre>
<p>produces an HTML file (and an md file) but no pdf file. </p>
<p>This latter example was the solution given to the <a href="https://stackoverflow.com/questions/25078572/specifying-multiple-simultaneous-output-formats-in-knitr">original question</a>. I have tried knitting with Shift-Ctrl-K and with the Knit button in RStudio, as well as calling <code>rmarkdown::render</code>, but only a single output format is created, regardless of the method I use to generate the output file.</p>
<p>Possibly related, but I could not identify solutions:</p>

For If Else Statement : <p>Working on this problem and I'm stuck. I know this should be a simple fix, but I'm not sure. I believe it's stuck in a for loop so the could keep on repeating but I'm not sure how to fix it. I tried adding a printf and scanf function, That didn't work. Adding a do while. that didn't work. I'm obviously making this thing harder than it needs to be. </p>

Is it really necessary to call delete on this pointer : <p>I have a pointer to a very large static array of objects that don't have any destructors nor they inherit from any class. This array is allocated at the beginning of the program and never allocated/relocated again (by design). This array needs to be destroyed only at the very end of the program. Do I really need to call delete for the array, or is it OK to let the OS (Windows) clean up? Deleting delays exiting of program by 5-10sec. Without calling delete, OS will do that for us and program exits immediately.</p>

How to create web listing system? (like amazon, ebay) : <p>I want to create an online listing system, where people can upload there listings and customers can buy them. It's comparable with the main idea of ebay, amazon,..</p>
<p>Basic functionality:</p>
<ul>
<li>Creating listings (uploading pictures, description,..)</li>
<li>Buying-System (People can put items in their chart & and buy them)</li>
<li>Log-In System (It should be possible to login as seller or buyer)</li>
</ul>
<p>My questions: What technique should I use for developing such an online system with a lot of database-queries? Would you recommend ASP.net or Java SPRING for implementing it? </p>
<p>Or what do you think about using Wordpress and Joomla? There are some usable templates, but I would have to customize them a lot. (Is it easy to develop own things in these CMS-systems?)</p>
<p>Thank you!</p>

Visual Studio 2015 (ASP.NET 5): show 'Manage Bower Packages...' context menu : <p>In Visual Studio 2015, when I create a brand new solution with a brand new ASP.NET 5 project, I see the <code>Manage Bower Packages...</code> context menu when I right-click on the project:</p>

How to find common sub strings in python? : <p>I am writing a python script where I have to find common substrings in many string sequences.
For example:</p>
<pre><code>sequence1 = 'mweitngaomjksjasper;36nnG1bmaso3th7a\-'
sequence2 = 'asngiqbwebs7-236jasper;u52dsv--4512G1b'
sequence3 = 'asvjaspermininwqmamnf-121xvxnesgq232'
</code></pre>
<p>jasper occurs 3 times - one time each in sequence1,sequence2 and sequence3.
G1b occurs 2 times - one time in sequence1 and one time in sequence 2.</p>
<p>For each substring occuring two times or more, i need to add them to a dictionary as substring => count.
In this case my dictionary will be:</p>
<pre><code>dict = { 'jasper': '3', 'G1b': '2'}
</code></pre>
<p>I will be using thousands of sequences to fill up this dictionary and if one substring occurs two or more times in any of the sequences, it
needs to be added to this dictionary. What would be the best way to do it without crashing the system?</p>

So I found some html/CSS exercises online and tried to copy them and so far so good but I can't level all my content and I'm not sure what to do
[This is the original][1]
and [this is what I have][2]

perl script for mounted disk space on Temp in Linux machine : I am new to perl world. I written one perl script for calculating free disk space. But whenever output generates, it gives me different number than what actually shows using df -h command.
So my requirement is i want to show specific mounted free disk space. E.g I want to show only /boot "Use%" figure and it should match with df -h command figure.
Please find my script for reference.

An Array with multiple information per index (an array of arrays???) (OBJ-C) : I am currently making a demo app which is calling a web api (following a tutorial that uses meetup.coms API's). I am passing the information into a tableview to display it and whilst making it I was thinking about this.
Can I make an array that has multiple pieces of data per row?
Almost like an excel spreadsheet so rather than having
NSArray *sampleArray1 = @[@"Name1",@"Name2",@"Name3"];
NSArray *sampleArray2 = @[@"Age1",@"Age2",@"Age3"];
and having to return the `[indexPath row]` of each array into your table view cell, you could instead have:
NSArray *superArray = @[@"Name1"|@"Age1", @"Name2"|@"Age2",@"Name3"|@""];
which would return all of your information for the selected index at once.
I am familiar with how you could do this in swift. I would normally create a `struct` and give it a few array variables.
struct superArray {
var names = [String]()
var ages = [String]()
}`
and I could simply do `cell.myLabel = superArray.names.indexPath[row]` (I might be getting some syntax wrong, I've not ran this through xcode.
When I setup my tableview I need to return something for the number of rows the table should display. Currently in my Objc project I have just implemented dummy arrays and all the arrays are the same size, I'm returning only one of these. This in my eyes is bad because I could retrieve a dataset with incomplete parameters (maybe an age but not a name) then my table will see the wrong amount of information in my array and not display correctly.
I almost want to return the struct's array count and have NO idea how I would do this. And I don't know how to do this in swift.. and I need to do this in objective c (since i've started working on an app that uses objc so I need all the practise I can get).
Currently my tableview works and I can populate the table with a dataset pulled from the web. I'm just thinking about defending my implementation from incomplete datasets and trying to 'theorycraft' the best solution to this problem.
If anyone has any suggestions I am all ears!
I'd prefer answers in objective c, but if you can explain the concept better in swift go for it, I can always try converting it over!
Cheers :)
As an end note: I have used matlab alot and I know you can basically tell an array to have a certain number of columns. So for example your array could have 4 columns per row all with different pieces of information per indexPath row (if that makes sense). I did alot of audio in matlab so maybe this 4 column array is a BFormat impulse response with 44100 samples (datapoints) and 4 numbers per sample (for WXYZ channels).
so as an example sample(row) 1 would return [0.123,-1.230,1.765,0.873] and sample (row) [1.322,-3.478,-0.311,0.421] (all random numbers)
You can specify in matlab which row to access AND which column to access, can this principle be extended into objc/swift/ios development? | 0debug |

Iterating over a two level structure using nested iterators : <p>I have the following two level <code>XML</code> structure. A list of boxes, each containing a list of drawers.</p>
<pre><code><Boxes>
<Box id="0">
<Drawers>
<Drawer id="0"/>
<Drawer id="1"/>
...
</Drawers>
</Box>
<Box id="1">
...
</Box>
</Boxes>
</code></pre>
<p>I'm parsing it using <code>StAX</code> and exposed the structure through two <code>Iterators</code>:</p>
<ol>
<li><code>BoxIterator implements Iterator<Box>, Iterable<Box></code></li>
<li><code>Box implements Iterable<Drawer></code></li>
<li><code>DrawerIterator implements Iterator<Drawer></code></li>
</ol>
<p>I can then do the following:</p>
<pre><code>BoxIterator boxList;
for (Box box : boxList) {
for (Drawer drawer : box) {
drawer.getId()
}
}
</code></pre>
<p>Under the hood of those <code>Iterators</code> I'm using <code>StAX</code> and both of them are accessing the same underlying <code>XMLStreamReader</code>. If I call <code>BoxIterator.next()</code> it will influence the result that will be returned on subsequent calls to <code>DrawerIterator.next()</code> because the cursor will have moved to the next box.</p>
<p>Does this break the contract of <code>Iterator</code>?
Is there a better way to iterate over a two level structure using <code>StAX</code>?</p>

Reminder of 28 / 8 is 3 .
3 comes in the range of 1 to 4. so print the number 5959 and go to next number. if reminder is not in the range of 1 to 4 ignore and go to next number.
So far i have tried this. but not happening
count = 0
lower = 5959
while (count<1000):
sum_digit= lower%8
count+=1
lower+=1
if 1<=sum_digit<=4:
print lower

Variable usage in C : <p>I'm a novice in C and came across code that seemed peculiar to me,</p>
<pre><code>extern int num;
int counter;
void init_counter() {
counter = 0;
}
int return_position() {
int pos = counter;
counter = counter * num;
return pos;
}
</code></pre>
<p>What is the point of the pos variable?
why can't I just do:</p>
<pre><code>extern int num;
int counter;
void init_counter() {
counter = 0;
}
int return_position() {
counter = counter * num;
return counter;
}
</code></pre>
<p>any help is appreciated</p>

IntelliJ - Import configuration from old version after first run : <p>I recently installed version 2017.2 of IntelliJ IDEA. I would like to keep my settings from my old 2017.1 version. IntelliJ's <a href="https://www.jetbrains.com/help/idea/install-and-set-up-intellij-idea.html#r_Install_and_set_up__product_.xmld320216e288" rel="noreferrer">support site</a> shows the following dialog box that is supposed to show up when you run the newly installed version for the first time.</p>
<p><a href="https://i.stack.imgur.com/gLJa2.png" rel="noreferrer"><img src="https://i.stack.imgur.com/gLJa2.png" alt="Complete Installation Dialog"></a></p>
<p>However, neither when I was installing the new version, nor when I ran the new version for the first time, was I ever shown this dialog box. I attempted to import settings from my old version via the <code>File | Import Settings</code> menu option, but it expects a <code>.jar</code> file that would have been exported from an old version by going to <code>File | Export Settings</code>, which I did not do in the old version before installing the new one.</p>
<p>I do still have all of the config from my old version in <code>%MY_HOME_DIR%/.IntelliJIdea2017.1</code>.
How can I import those settings in the same way that the above dialog box would have done had it shown up when I opened the new version for the first time?</p>

PHP - Anti mitm attack idea : <p>I've got an idea against mitm(man-in-the-middle) attacks that i'd like to implement to my site, so i decided to ask you how secure this is. First i'd get 10 page loading times from the client computer in seconds. Then i'd calculate the standard with all those loading times. Then each time the user loads a new page i check if his/her ip address has changed and if it has i recalculate that standard and compare it to the previous standard. If this standard is 1 or 2 bigger that doesn't really matter, but if it's 4 i can log out the user. Then if the attacker has a slower internet connection he would get logged out. I'm sure i'm not the only one who has thought of this, but i don't know if this is used.</p>
