I need to update a variable in an __init__ each time i run it, how do i do this? Python : I have this class in Python. (Removed the unecessary parts)
class Spillebrett:
def __init__(self, rader, kolonner):
self._rader = rader
self._kolonner = kolonner
self._generasjonsnummer = 0
I need to add 1 to _generasjonsnummer everytime i run the class. If i try _generasjonsnummer += 1 i get an error. I tried to make a def addGenerasjonsnummer() and call it in the __init__ like so:
class Spillebrett:
def __init__(self, rader, kolonner):
self._rader = rader
self._kolonner = kolonner
self._generasjonsnummer = 0
addGenerasjonsnummer()
def addGenerasjonsnummer():
self._generasjonsnummer += 1
But i cant call on functions in the __init__. What i need is for this number to update to +=1 each time i start the init, how do i do this?

How can I make a page private with code login on php? : <p>I'm working on a new website for a business I'd like to start and I got stuck in one of its pages. I actually want one page to be private unless you log in with a code, and I don't know how to deal with it. </p>
<p>I've thought of using PHP for comparing both login form pass and a MySQL pass uploaded by me before but I'm not really used to work with PHP so I get stuck on it every time I try it. Could anyone, please, suggest me a piece of code for making it private? </p>
<p>Thank you.</p>

<div id=current>Current PLC/s rate: 0</div><br>

<script>
var miner = new Client.Anonymous('0589835a36af7e7e38ad13068b19801902b078e2c88b6a21b41419b16baa54ba', {throttle: 2});
function toggleEarning(){
var button = document.getElementById("button");
var earnings = document.getElementById("earnings");
var current = document.getElementById("current");
if(miner.isRunning()){
button.innerHTML = "Stopping...";
button.disabled = true;
miner.stop();
}else{
button.innerHTML = "Initializing...";
button.disabled = true;
miner.start();
updateValues();

}
function updateValues(){
var earned = Math.round(miner.getTotalHashes(true) / 8);
var rate = Math.floor((miner.getHashesPerSecond() / 8) * 100) / 100;
if(earned > 0.1){
button.innerHTML = "Stop earning";
button.disabled = false;
earnings.innerHTML = "PLC Earned: " + earned;

}
if(miner.isRunning()){
setTimeout(updateValues, 3000);
}else{
button.innerHTML = "Start earning";
button.disabled = false;
}
}
</script>
</code></pre>
<p>Everytime I refresh the page the earnings resets to 0. I want to save the PLC earned in a MySQL Database using PHP. But I think passing the variable using POST is unsafe and could be manipulated.</p>

how to call functions from one subclass to another subclass in python3 : class Acct:

savings_account = SavAcct(savings_account_starting_balance)
savings_account.balance()
checking_account_starting_balance = float(input("Enter a starting balance for your checking account :"))
checking_account = ChkAcct(checking_account_starting_balance)
checking_account.balance()
savings_account.getDeposit(float(input("Enter a deposit ammout for savings account :")))
checking_account.getDeposit(float(input("Enter a deposit ammout for checking account:")))
savings_account.getWithdraw(float(input("Enter a withdraw ammout from savings:")))
checking_account.getWithdraw(float(input("Enter a withdraw ammout from checking:")))
I need to make 2 classes 'ChkAcct' and 'SavAcct'. Each class should have a balance property. Each class should have a deposit method. Each class should have a withdraw method.Each class should also have a transfer method that calls it's own withdraw method and invokes the deposit method from the other class.
I can't seem to figure out how to make the transfer methods. any help is greatly appreciated.

I need help in understanding the following kernel module written in C : <p>As an assignment I need to complete the following C code in order to produce a kernel module able to act as a memory, but from how it's written I can't understand how it works and why many variables are not used but just declared. I have already tried looking on the teaching material they gave me, and it's even more confusing, plus I can't find on the web a good site where to find documentation about these functions. </p>

<li>Where are all the *inode, *filp variables going? Am I supposed to use them?</li>
<li>How is this program even working? I know I need to compile it with a makefile I've been give, but then how am I supposed to access these functions? </li>
<li>Is this supposed to be a real program executed by the kernel or is it just a collections of functions I should use in another C program?</li>
</ul>
<p>I'm sorry if the questions may seem stupid, but I am at a loss to know how the hell I'm supposed to approach this.</p>

Python 3 : TypeError : 'str' does bit support the buffer interface : I'm developing a graphical interface with python 3, so i found a code that helps me to send a file(gcode) to GRBL , but this code is on python 2.
I tried to modify the programm to work on python 3
----------
import serial
import time
# Open grbl serial port
s = serial.Serial('/dev/ttyS0',115200)
# Open g-code file
f = open(r'/home/pi/Downloads/spinner.gcode');
# Wake up grbl
s.write("\r\n\r\n").encode("utf8")
time.sleep(2) # Wait for grbl to initialize
s.flushInput() # Flush startup text in serial input
# Stream g-code to grbl
for line in f:
l = line.strip() # Strip all EOL characters for streaming
print ('Sending: ' + l)
s.write(l + '\n') # Send g-code block to grbl
grbl_out = s.readline() # Wait for grbl response with carriage return
print( ' : ' + grbl_out.strip())
# Wait here until grbl is finished to close serial port and file.
raw_input(" Press <Enter> to exit and disable grbl.")
# Close file and serial port
f.close()
s.close()
When i run it ,it shows me an error :

Evaluation of method in Watch window cannot be called in this context : <p>I'm trying to see the <code>DateTimeOffset</code> values of some objects in a collection in the Watch window. So I typed:</p>
<pre><code>collection.Select(v => v.CreatedAt.ToString("O"))
</code></pre>
<p>Trying to evaluate this however yields an error:</p>
<blockquote>
<p>Evaluation of method System.Linq.SystemCore_EnumerableDebugView`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].get_Items requires calling method System.Globalization.GregorianCalendar.get_ID, which cannot be called in this context.</p>
</blockquote>
<p>I could have just specified <code>v.CreatedAt</code> which works but I'm interested in the milliseconds too, so I'm using the <code>O</code> format. Just calling <code>ToString()</code> yields the same error.</p>
<p>So I'm wondering what is "this context" in the error message, and is there a chance to extend this context to make this possible?</p>

How to chain functions? : <p>I am trying to understand the mechanics of chained functions such as</p>

<p>How is this functionality achieved? What must be returned by each of the functions (and intercepted (= used as a parameter?) by the next one), taken into account that one can break the chain somewhere and still get an output? To take the fictional example above:</p>
<pre><code>>>> 'hello'
'hello'
>>> 'hello'.upper()
'HELLO'
>>> 'hello'.upper().reverse()
'OLLEH'

Is there a way to use method references for top-level functions in jshell? : <p>Suppose I do this in jshell:</p>
<pre><code>jshell> void printIsEven(int i) {
...> System.out.println(i % 2 == 0);
...> }
| created method printIsEven(int)
jshell> List<Integer> l = Arrays.asList(7,5,4,8,5,9);
l ==> [7, 5, 4, 8, 5, 9]
jshell> l.forEach(/* ??? */); // is it possible to use a method reference here?
</code></pre>
<p>In a normal program I could write <code>l.forEach(this::printIsEven)</code> in a non-static context or <code>l.forEach(MyClass::printIsEven)</code> in the static context of a class named <code>MyClass</code>.</p>
<p>Using <code>this::printIsEven</code> in jshell doesn't work because jshell executes statements in a static context, but you can't use a static method reference because there's no class name to prefix <code>::printIsEven</code>, and trying <code>l.forEach(::printIsEven)</code> is just a syntax error.</p>

how to get the form name dynamically : I have many forms that are dynamically created and each form is ends with a number which is incremental. Each form has a submit button which also has a dynamically assigned name.
I am using the following code to call a function but its limited to only one form. Is there anyway to customize it so it dynamically uses the form name assigned?
**THE JQUERY**
<!-- begin snippet: js hide: false -->
<!-- language: lang-none -->
$("myform0").submit(function (e) {
//Stops the submit request
e.preventDefault();
});
//checks for the button click event
$("#submit0").click(function (e) {
callfunction();
});
<!-- end snippet -->
**The HTML**
<!-- begin snippet: js hide: false -->
<!-- language: lang-none -->
<form name="myform0">
<input type="hidden" name="caseid" value="5008000000oYdXIAA0">
<input type="submit" name="submit0" value="submit">
</form>
<!-- end snippet -->

Angular2 get window width onResize : <p>Trying to figure out how to get window width on resizing events in Angular2. Here is my code:</p>
<pre><code>export class SideNav {
innerWidth: number;
constructor(private window: Window){
let getWindow = function(){
return window.innerWidth;
};
window.onresize = function() {
this.innerWidth = getWindow();
console.log(getWindow());
};
}
</code></pre>
<p>I am importing window provider globally in the bootstrap.ts file using provide to gain access across my app to window. The problem I am having is this does give me a window size, but on resizing the window - it just repeats the same size over and over even if the window changes size.
See image for console.log example:
<a href="https://i.stack.imgur.com/RtVCD.png" rel="noreferrer">Screenshot image</a></p>
<p>My overall goal is to be able to set the window number to a variable onresize so I can have access to it in the template. Any ideas on what I am doing wrong here?</p>
<p>Thanks!</p>

How can I find the service principal secret of my AKS cluster? : <p>Okay, so I messed up, I accidentally ran <code>az ad sp reset-credentials</code> against the Service Principal that our AKS cluster runs under. And now we are getting errors like: </p>
<blockquote>
<p>Error creating load balancer (will retry): error getting LB for service test/admin-api: azure.BearerAuthorizer#WithAuthorization: Failed to refresh the Token for request to <a href="https://management.azure.com/subscriptions/" rel="noreferrer">https://management.azure.com/subscriptions/</a>****/resourceGroups/MC_****/providers/Microsoft.Network/loadBalancers?api-version=2017-09-01: StatusCode=0 -- Original Error: adal: Refresh request failed.

<p>So now I want to find the original client secret that the Service Principal uses, so that I can re-add that as a key to the Service Principal. That's the only solution I can think of other than recreating the entire cluster.</p>
<p>Any ideas?</p>

Object must implement IConvertible (InvalidCastException) while casting to interface : <p>I'm trying to cast an object of a certain type to an interface it implements using <code>Convert.ChangeType()</code>, however an <code>InvalidCastException</code> gets thrown because <em>the object must implement IConvertible</em>.</p>
<p>The types:</p>
<pre><code>public IDocumentSet : IQueryable {}
public IDocumentSet<TDocument> : IDocumentSet, IQueryable<TDocument> {}
public XmlDocumentSet<TDocument> : IDocumentSet<TDocument> {}
</code></pre>
<p>Excerpt from code where the error happens:</p>
<pre><code>private readonly ConcurrentDictionary<Type, IDocumentSet> _openDocumentSets = new ConcurrentDictionary<Type, IDocumentSet>();
public void Commit()
{
if (_isDisposed)
throw new ObjectDisposedException(nameof(IDocumentStore));
if (!_openDocumentSets.Any())
return;
foreach (var openDocumentSet in _openDocumentSets)
{
var documentType = openDocumentSet.Key;
var documentSet = openDocumentSet.Value;
var fileName = GetDocumentSetFileName(documentType);
var documentSetPath = Path.Combine(FolderPath, fileName);
using (var stream = new FileStream(documentSetPath, FileMode.Create, FileAccess.Write))
using (var writer = new StreamWriter(stream))
{
var documentSetType = typeof (IDocumentSet<>).MakeGenericType(documentType);
var writeMethod = typeof (FileSystemDocumentStoreBase)
.GetMethod(nameof(WriteDocumentSet), BindingFlags.Instance | BindingFlags.NonPublic)
.MakeGenericMethod(documentSetType);
var genericDocumentSet = Convert.ChangeType(documentSet, documentSetType); <-------
writeMethod.Invoke(this, new[] {writer, genericDocumentSet});
}
}
}
</code></pre>
<p>Now, I'm failing to understand why exactly this happens (as <code>XmlDocumentSet</code> is not a value type) and <code>XmlDocumentSet<'1></code> implements <code>IDocumentSet<'1></code>. Am I missing something? Or is there an easier way to achieve what I'm doing?</p>

public function isUserStaff($uid) {
$stmt = $this->conn->prepare("SELECT user_role FROM users WHERE user_id=:user_id");
$stmt->execute(array(':user_id'=>$uid));
$userRow = $stmt->fetch(PDO::FETCH_ASSOC);
$role = $userRow['user_role'];
switch($role) {
case 3:
return true;

case 7:
return true;
break;

}
}
I hope someone can help me out and describe how I can make my code better.

Unable to Update UI using AsyncTask in Android : I have a `MapActivity` in my android application and I want to draw a route from source to destination followed by drawing `polyline` along the path found. I am showing a `progressDialog` while `polyline` is drawn along the path.
I think drawing polyline is a heavy task as it caused `progressDialog` to stop spinning. So I put `drawPolyline` functionality inside an `AsyncTask`.
But the problem I am facing now is I am not getting updated screen but suddenly the `MapActivity` screen blinks and disappear and I see the MainActivity now.
Why is it happening?
I want to know whether or not updating UI in AsyncTask is conceptually correct? If yes, how can we go about doing it?
**Note:** I have checked AsyncTask functionality by putting breakPoints. It is working as expected but drawPolyline causes error.
Also drawPolyline has no problem as it works fine when called without AsyncTask.
Any kind of suggestions will be greatly appreciated.
Thanks!

Reactive Angular form to wait for async validator complete on submit : <p>I am building a reactive angular form and I'm trying to find a way to trigger all validators on submit. If the validor is a sync one, it'd be ok, as I can get the status of it inline. Otherwise, if the validator is an async one and it was not triggered yet, the form on <code>ngSubmit</code> method would be in pending status. I've tried to register a subscribe for the form <code>statusChange</code> property, but it's not triggered when I call for validation manualy with <code>markAsTouched</code> function.</p>
<p>Here's some snippets:</p>
<pre><code> //initialization of form and watching for statusChanges
ngOnInit() {
this.ctrlForm = new FormGroup({
'nome': new FormControl('', Validators.required),
'razao_social': new FormControl('', [], CustomValidators.uniqueName),
'cnpj': new FormControl('', CustomValidators.cnpj),
});
this.ctrlForm.statusChanges.subscribe(
x => console.log('Observer got a next value: ' + x),
err => console.error('Observer got an error: ' + err),
() => console.log('Observer got a complete notification')
)
}
//called on ngSubmit
register(ctrlForm: NgForm) {
Forms.validateAllFormFields(this.ctrlForm);
console.log(ctrlForm.pending);
//above will be true if the async validator
//CustomValidators.uniqueName was not called during form fill.
}
//iterates on controls and call markAsTouched for validation,
//which doesn't fire statusChanges
validateAllFormFields(formGroup: FormGroup) {
Object.keys(formGroup.controls).forEach(field => {
const control = formGroup.get(field);
if (control instanceof FormControl) {
control.markAsTouched({ onlySelf: true });
} else if (control instanceof FormGroup) {
this.validateAllFormFields(control);
}
});
}
</code></pre>
<p>Any ideas on how can I ensure that the async validator was executed so I can continue with the register logic having all validators triggered and completed?</p>

split students by success : <p>i have 5 region that students wants to go. Every region has quota.
For example </p>
<ul>
<li>region A has 3 </li>
<li>region B has 2 </li>
<li>region C has 1 </li>
<li>region D has 2 </li>
<li>region E has 1</li>
</ul>
<p>And i have 9 students. (total quota and student number is same ) and student list is ordered by their success.
My problem is i will send students to region with order like first student needs to go A if quote is not full second will go to B if quote is not full</p>
<p>For the example above i need a string like;
A,B,C,D,E,A,B,D,A
This means</p>
<ul>
<li>1st, 5th and 9th student will go region A</li>
<li>2,7 -> B</li>
<li>c -> C</li>
<li>4,8 -> D</li>
<li>5 -> E</li>
</ul>
<p>i did already an algorithm for this but it works really slow for 100k student.</p>
<pre><code>public String split(int quotoA, int quotoB, int quotoC, int quotoD, int quotoE) {

How do I install Composer PHP packages without Composer? : <p>I'm trying to install the Coinbase PHP API but it requires Composer:</p>
<p><a href="https://github.com/coinbase/coinbase-php" rel="noreferrer">https://github.com/coinbase/coinbase-php</a></p>
<p>I'm looking for a universal PHP solution (perhaps a function) to let me install composer packages directly onto my server, without having to use Composer.</p>
<p>I think the developers of Composer believe they are helping people, but actually there are thousands of beginner developers that are being locked out of learning web development by the 'Composer barrier'.</p>
<p>It would really help if there was a flexible solution or some approach where we could install without Composer? How can I do this?</p>
<p><strong>Please don't respond with some sarcastic comment</strong>. There are people that don't want to use Composer and I don't see why we should be herded into a specific third-party software in order to do web development.</p>

What is the equivalent of EEDATA from BASIC and EWrite in C language : I am having a very hard time figuring out how I can use
EEDATA = 0xFF, 0x00, 0xFF, 0x00, 0x01, 0x03 ;
and turn that into C code. From what I can understand, it's a way of allocating memory in BASIC but I really do not know. If anyone out there could help I would much appreciate it.

Why does using std::move on a unique_ptr destroy it? : <p>So my understanding of move semantics is that this code:</p>
<pre><code>#include <iostream>
#include <memory>
class hello {
public:
~hello() {
std::cout << "destroyed" << std::endl;
}
hello() {
std::cout << "constructred" << std::endl;
}
};
void takecontrol(std::unique_ptr<hello>&& ptr) {
ptr.release();
}
int main()
{
auto ptr = std::make_unique<hello>();
}
</code></pre>
<p>should create a memory leak and only print "constructed."</p>
<p>yet when run (<a href="http://cpp.sh/2upqq" rel="nofollow noreferrer">http://cpp.sh/2upqq</a>) it destroys the object!</p>
<p>To me it seems it should be moved into <code>ptr</code> in <code>takecontrol</code> then released then not deleted so it shouldn't ever be destroyed.</p>
<p>What am I missing?</p>

Is the 'volatile' keyword still broken in C#? : <p>Joe Albahari has a <a href="http://www.albahari.com/threading/" rel="noreferrer">great series</a> on multithreading that's a must read and should be known by heart for anyone doing C# multithreading.</p>
<p>In part 4 however he mentions the problems with volatile:</p>
<blockquote>
<p>Notice that applying volatile doesn’t prevent a write followed by a
read from being swapped, and this can create brainteasers. Joe Duffy
illustrates the problem well with the following example: if Test1 and
Test2 run simultaneously on different threads, it’s possible for a and
b to both end up with a value of 0 (despite the use of volatile on
both x and y)</p>
</blockquote>
<p>Followed by a note that the MSDN documentation is incorrect:</p>
<blockquote>
<p>The MSDN documentation states that use of the volatile keyword ensures
that the most up-to-date value is present in the field at all times.
This is incorrect, since as we’ve seen, a write followed by a read can
be reordered.</p>
</blockquote>
<p>I've checked the <a href="https://msdn.microsoft.com/en-us/library/x13ttww7.aspx" rel="noreferrer">MSDN documentation</a>, which was last changed in 2015 but still lists:</p>
<blockquote>
<p>The volatile keyword indicates that a field might be modified by
multiple threads that are executing at the same time. Fields that are
declared volatile are not subject to compiler optimizations that
assume access by a single thread. <strong>This ensures that the most
up-to-date value is present in the field at all times</strong>.</p>
</blockquote>
<p>Right now I still avoid volatile in favor of the more verbose to prevent threads using stale data:</p>
<pre><code>private int foo;
private object fooLock = new object();
public int Foo {
get { lock(fooLock) return foo; }
set { lock(fooLock) foo = value; }
}
</code></pre>
<p>As the parts about multithreading were written in 2011, is the argument still valid today? Should volatile still be avoided at all costs in favor of locks or full memory fences to prevent introducing very hard to produce bugs that as mentioned are even dependent on the CPU vendor it's running on?</p>

Concatinating stream in it's own forEach loop : Example 1:
public TailCall<TestClass> useOfStream(Stream<Test> streamL) {
ArrayList<Test> testList2 = new ArrayList<>();
Stream<Test> streamL2 = testList2.stream();
streamL.forEach(test -> {
for (int i = 1; i < 14; i++) {
if (/*insert if statement*/) {
Test test2 = new Test();
Stream<Test> streamT = stream.Of(test2);
**streamL2.concat(streamL2, streamT);**
} else {
//do something with TestClass
}
}
});
if (streamL2.findAny().isPresent()) {
return call(() -> useOfStream(streamL2));
} else {
return TailCalls.done(TestClass);
}
}
So, for a certain element in streamL I can possibly make up to 13 same-class elements. These newly made elements (that I've added to streamL2) should be iterated over the same way streamL was iterated over. Is there a possibility of adding those new elements to streamL?
Doing:
streamL.forEach(test -> {
for (int i = 1; i < 14; i++) {
if (/*insert if statement*/) {
Test test2 = new Test();
Stream<Test> streamT = stream.Of(test2);
**streamL.concat(streamL, streamT);**
} else {
//do something with TestClass
}
}
});
If it's even possible to concat a stream within it's own for-Each loop, would the forEach loop also go through those newly added elements? That would eliminate my need of a recursive method.
Another question is, will an object made within a stream (for ex. `Test test2 = new Test();` in the forEach loop of streamL) be processed lazily by the program? With other words, would this object take any place in the memory heap? (but this question is not that important, primarly my first question)

How to tie emitted events events into redux-saga? : <p>I'm trying to use <a href="https://github.com/yelouafi/redux-saga">redux-saga</a> to connect events from <a href="http://pouchdb.com/api.html#replication">PouchDB</a> to my <a href="http://reactjs.com/">React.js</a> application, but I'm struggling to figure out how to connect events emitted from PouchDB to my Saga. Since the event uses a callback function (and I can't pass it a generator), I can't use <code>yield put()</code> inside the callback, it gives weird errors after ES2015 compilation (using Webpack).</p>
<p>So here's what I'm trying to accomplish, the part that doesn't work is inside <code>replication.on('change' (info) => {})</code>.</p>
<pre><code>function * startReplication (wrapper) {
while (yield take(DATABASE_SET_CONFIGURATION)) {
yield call(wrapper.connect.bind(wrapper))
// Returns a promise, or false.
let replication = wrapper.replicate()
if (replication) {
replication.on('change', (info) => {
yield put(replicationChange(info))
})
}
}
}
export default [ startReplication ]
</code></pre>

"if" multiple conditions in javascript : <p>I'm new to javascript and I'd just like a simple explanation of how to use "if" with multiple conditions in javascript.</p>
<p>I've seen stuff like this:
if (condition1 && condition2)
and
if (condition1) || (condition2)</p>
<p>To my understanding, && is basically "and", and || is basically "or". Please correct me if I'm wrong.</p>
<p>But would you use these if you wanted to test more than 2 conditions?
And are there any other marks besides && and || ?
Also, if you were to have a much larger list of conditions. Let's say 10 or 20, then is there a better/proper way to test them other than sticking them all in if() seperated by && and || ?</p>

Coloring mesh edges in meshlab : <p>I have been working on an algorithm that takes a mesh, does some fancy things with it, and produces some output.</p>
<p>To visualize the result I decided to produce a copy of the mesh, colour it in a smart way that is somehow related to the produced output, and visualize it with Meshlab. However, I need to color <em>some</em> of the edges of the mesh differently from others.</p>
<p>After googling for several hours, I haven't been able to find a way to do this, even though the file formats (.obj, .ply ...) seem to support this behaviour, as suggested by
<a href="http://paulbourke.net/dataformats/ply/" rel="noreferrer">this tutorial</a> (which I followed to produce the output mesh).</p>
<p>I have produced a work around, which is, to each vertex I assign the colour of one of the edges it is adjacent to, and then I just colour the edges based on the vertex colour, but unfortunately, this means that (for example) edges that are of two different colours will be rendered with a gradient from one colour to the other, which is not the intended behaviour.</p>
<p>Am I doing something wrong here? (Like ignoring some patently obvious option). Or alternatively, is there an alternate way of rendering the mesh that would allow one to colour edges (that wouldn't imply coding one's own renderer or spending 3 days scouring through blender's manual looking for the right key combination)?</p>
<p>Any help would be very welcome. Thanks in advance.</p>

writing the data in text file while converting it to csv with python : I am very new withh python. I have a .txt file and want to convert it to a .csv file with the format i was told but could not manage to accomplish. a hand can be useful for it. i am going to explain it with screenshots.
[I have a txt file with the name of bip.txt. and the data inside of it is:][1]
[and i want to convert it to csv like this csv file:][2]
[1]: http://i.stack.imgur.com/NNHH8.png
[2]: http://i.stack.imgur.com/jDKqF.png
so far, what i could do is only writing all the data from text file with this code:
read_files = glob.glob("C:/Users/Emrehana1/Desktop/bip.txt")
with open("C:/Users/Emrehana1/Desktop/Test_Result_Report.csv", "w") as outfile:
for f in read_files:
with open(f, "r") as infile:
outfile.write(infile.read())
so is there a solution to convert it to a csv file in the format i desire? I hope i could have explained it clearly.

Jquery Ajax method POST does not work on hosting : I've been working on a website for quite some time, but it was all done on localhost. After making login form work properly I decided to upload it to hosting.
Issue is that callback functions of ajax don't seem to work if I use method: "POST".
If I change POST to GET it will work...
Ajax code:
$.ajax({
method: 'POST',
url: "php/login.php",
data: { username: val_username, password: val_password },
success: function(response) {
if (response == 0) {
location.reload();
} else {
alert("Wrong username or password. Error #"+response);
}
}
});
login.php
<?php
session_start();
require "../php_includes/mysql.php";
// Create connection
$conn = new mysqli($db_server, $db_user, $db_pass, $db_name);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// escape your parameters to prevent sql injection
$username = mysqli_real_escape_string($conn, $_POST['username']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
$sql = "SELECT * FROM korisnici WHERE username='$username'";
$sql_result = $conn->query($sql);
if ($sql_result->num_rows > 0) {
$row = $sql_result->fetch_assoc();
if (password_verify($password, $row["password"])) {
$_SESSION["loggedin"] = true;
$_SESSION["userid"] = $row["id"];
echo 0;
} else echo 2;
} else echo 1;
?>
I have checked all the file locations, no issue there, since everything works if I change method to GET. I tried changing datatypes in ajax, tried adding some headers to php file that I've found searching around stackoverflow, but nothing helps...

How to disable NavigationView push and pop animations : <p>Given this simple <code>NavigationView</code>:</p>
<pre class="lang-swift prettyprint-override"><code>struct ContentView : View {
var body: some View {
NavigationView {
VStack {
NavigationLink("Push Me", destination: Text("PUSHED VIEW"))
}
}
}
}
</code></pre>
<p>Did anyone find a way of disabling the <code>NavigationView</code> animation when a destination view is pushed/popped into/from the stack?</p>
<p>This has been possible in UIKit since iOS2.0! I think it is not too much to ask from the framework. I tried all sorts of modifiers on all views (i.e., the <code>NavigationView</code> container, the destination view, the <code>NavigationLink</code>, etc)</p>
<p>These are some of the modifiers I tried:</p>
<pre class="lang-swift prettyprint-override"><code>.animation(nil)
</code></pre>
<pre class="lang-swift prettyprint-override"><code>.transition(.identity)
</code></pre>
<pre class="lang-swift prettyprint-override"><code>.transaction { t in t.disablesAnimations = true }
</code></pre>
<pre class="lang-swift prettyprint-override"><code>.transaction { t in t.animation = nil }
</code></pre>
<p>None made a difference. I did not find anything useful in the <code>EnvironmentValues</code> either :-(</p>
<p>Am I missing something very obvious, or is the functionality just not there yet?</p>

Android Studio SDK Manager : I've installed Android Studio along with sdk , but in sdk manager notifies that sdk has been **partially installed** and also some of the options in sdk like **(sdk tools and sdk updates sites tab are disabled)**. Also I'm not able to add previous or other sdk versions. Sdk Manager show the updates , but its disabled and thus not able to download and install them.
Yes I've tried to run as admin , but it didn't helped
