74,120,082 | <p>I have one function <code>funA</code> on component A, <code>ComponentA</code> and another component B, <code>componentB</code>. Now, I want to <code>ComponentB</code> to use this same function, <code>funA</code>.</p>
<p>How can I share this <code>funA</code> to <code>ComponentB</code>?</p>
<p>I was thinking about <code>redux</code>, but redux doesn't suggest passing a non-serializable value, like a function, to a state.</p>
<p>What's the solution for this?</p>
<p>Edit: the <code>funA</code> persisting some states of <code>componentA</code>, I want to keeping these states when using on <code>componentB</code>. I was trying to create a custom hook, however the hook is a individual closure for each time call the hook, which means I cannot hold the state.</p>
<p>Edit: I have created a custom hook, but it's not working, maybe I should include some codes.</p>
<p>On my custom hook:</p>
<pre><code>const useActionsHook = () => {
const [action, setAction] = useState([])
const addAction = (actionNew) => {
setAction(prev=>[...prev, actionNew])
}
const getActions = () => {
return action
}
return {
getActions, addAction
}
}
</code></pre>
<p>In ComponentA, I call <code>const {addAction} = useActionsHook</code> then save the action. And on ComponentB, I call <code>const {getActions} = useActionsHook</code> then to get actions, but that <code>getActions</code> value is still the empty array.</p>

74,120,130 | <p>I'd like to use a protocol as an interface but I'm having trouble working it out in Swift. Can someone make sense of this error and point me in the right direction?</p>
<p>Maybe I'm thinking of protocols in a completely improper way.</p>
<p>Here is sample code:</p>
<pre class="lang-swift prettyprint-override"><code>protocol State {
associatedtype U: State
static func fromString(_: String) -> U
}
class ConcreteState1: State {
static func fromString(_ value: String) -> ConcreteState1 {
return ConcreteState1()
}
}
protocol Loader {
associatedtype T: State
func load(completion: (Result<T.U, Error>) -> Void)
}
extension Loader {
func load(completion: (Result<T.U, Error>) -> Void) {
let value = T.fromString("")
completion(.success(value))
}
}
class ConcreteState1Loader: Loader {
typealias T = ConcreteState1
}
// Abstraction to deal with various types of state
var mainState: (any State)?
// Needs to be an abstraction using the protocol because the specific loader is injected
// This is just a simplified reproduction of the issue
var loader: any Loader = ConcreteState1Loader()
// ERROR: Member 'load' cannot be used on value of type 'any Loader'; consider using a generic constraint instead
loader.load { result in
if let state = try? result.get() {
mainState = state
}
}

74,120,204 | <p>Consider this situation:
(undirected graph)
we dont have number of nodes but have the edges like 1<->3 , 6<->7, 3<->7. So how do we declare a graph using this?</p>
<p>Generally we have n that is no. of node and e edges but in this case we only have e edges and that too not continuous i.e. instead of 1,2,3,4(or zero indexed) we have 1,3,6,7.
I know we should use a map to convert these 1,3,6,7 values to 1,2,3,4 but how?</p>
<p>how we generally declare a graph</p>
<pre><code>vector<int> adj[100000];
for(int i=0;i<e;i++)
{
int u,v;
cin>>u>>v;
//need some mapping technique here to make this continuous
adj[u].push_back(v);
adj[v].push_back(u);
}
//iterate according to situation

74,120,217 | <p>I have implemented a CSS-based sticky header using CSS like</p>
<pre><code>nav {

<p>I implemented it just find this page in edcint.co.nz/public/data/scenery (copy and paste this link otherwise it will load a blank page)</p>
<p>But in a related page, that uses a lot of the same code and css (same lazy loading and infinite scroll), the header seems to come and go as you scroll down the page. Once you reach the bottom of page (lazy loading and infinite scroll are in play here - but same as on the page that works ok), then the header works ok.

74,120,298 | <p>I have difficulty breaking a class consisting of one method into smaller methods. I have a simple socket class that Initiate, send and receive a message in one step (one method). Now I would like to divide this into separate steps of Initialization, Send, Receive, and End as below. I have tried so many different combinations but I could not get it working.</p>
<p>My program that works fine:</p>
<pre><code>using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.IO;
namespace SocketCom
{
internal class Program
{
public class SyncSocketClient
{
public static void StartClient() \\<<-----------
{
byte[] bytes = new byte[1024];
var hostName = Dns.GetHostName();
IPHostEntry ipHost = Dns.GetHostEntry(hostName);
IPAddress ip = ipHost.AddressList[1];
IPEndPoint remoteEP = new IPEndPoint(ip, 11111);
Socket sender = new Socket(ip.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
sender.Connect(remoteEP);
sender.RemoteEndPoint.ToString();
byte[] msg = Encoding.ASCII.GetBytes("Hello");
int byteSent = sender.Send(msg);
int byteReceived = sender.Receive(msg);
Console.WriteLine($"[ECHO TEST] {Encoding.ASCII.GetString(bytes, 0, byteReceived)}");
sender.Shutdown(SocketShutdown.Both);
sender.Close();
}
}
static void Main(string[] args)
{
SyncSocketClient.StartClient();
}
}
}
</code></pre>
<p>What I would like to below (not working). I do not care about the access modifier or being static or not. I just want to break one method into three separate methods in any possible way.</p>
<pre><code>using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.IO;
namespace SocketCom
{
internal class Program
{
public class SyncSocketClient
{
public static void StartClient()\\<<-----------

byte[] bytes = new byte[1024];
var hostName = Dns.GetHostName();
IPHostEntry ipHost = Dns.GetHostEntry(hostName);
IPAddress ip = ipHost.AddressList[1];
IPEndPoint remoteEP = new IPEndPoint(ip, 11111);
Socket sender = new Socket(ip.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
sender.Connect(remoteEP);
}
public static void Send(string message)\\<<-----------
{
sender.RemoteEndPoint.ToString();
byte[] msg = Encoding.ASCII.GetBytes(message);
int byteSent = sender.Send(msg);
}
public static void Receive()\\<<-----------
{
int byteReceived = sender.Receive(msg);
Console.WriteLine($"[ECHO TEST] {Encoding.ASCII.GetString(bytes, 0, byteReceived)}");
}
public static void EndClient()\\<<-----------
{
sender.Shutdown(SocketShutdown.Both);
sender.Close();
}
}

{
SyncSocketClient.StartClient();
SyncSocketClient.StartClient("Hello");
SyncSocketClient.Receive();
SyncSocketClient.EndClient();

74,120,410 | <p>I made two apps with similar code on Spring Boot.</p>
<ol>
<li>Reactive Netty spring boot webflux r2dbc.</li>
<li>Nonreactive Tomcat spring boot postgres.</li>
</ol>
I expect reactive one is faster or has the same speed. But it is slower 6th time.
I don't see any blocks there. In my opinion it is fully nonblocking app. Why so slowly?
For testing I have been using J-METER.
200 threads 200 times
getAll 400 strings
Latency of response nonreactive app - 190-240 ms.
Latency of response reactive app - 1290-1350 ms.

<p>Finally, I output the value of each position of the whole array.</p>
<p>Is there any constant optimization to speed up the intermediate modification operations?</p>

74,120,624 | <p>I am getting the points dynamically, I have to fill the area under the polyline. I have tried the <strong>fill</strong> property but that would not result in what I have expected, screenshot attached.</p>
<pre><code> <svg
viewBox={`0 0 ${points.length * 10} 100`}
height="100%"
width="150px"
>
<polyline fill="rgba(0,116,217,0.5)" stroke="#0074d9" stroke-width="5" points={points} />
</svg>
</code></pre>
<p>the output is something like this</p>
<p><a href="https://i.stack.imgur.com/vNIkc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vNIkc.png" alt="the output is something like this" /></a></p>
<p>and I want it to be something like this</p>
<p><a href="https://i.stack.imgur.com/p431U.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/p431U.png" alt="enter image description here" /></a></p>
<p>I have already tried different solutions to that, like by using a <strong>path</strong> instead of using a polyline, but It is a little bit more complex if we have dynamic co-ordinates (points).</p>

74,120,626 | <p>I'm able to compile both Tcl and Tk just fine on Windows 10 using Visual Studio 2019 developer command prompt. Both have <code>win\makefile.vc</code> file. <code>nmake -f makefile.vc</code> will build them successfully.</p>
<p>However, TkTreeCtrl source code located at the following location doesn't seem to have <code>makefile.vc</code> anywhere.</p>

74,120,636 | <p>I want to count what is the number of each age for each gender, basically to see the distribution of age and gender.</p>
<p>A sample of the data is like</p>
<pre><code>state poi_name gender age
aichi starbucks shop E 2 3
aichi starbucks shop G 0 2
aichi starbucks shop G 1 2
chiba starbucks shop A 0 1
chiba starbucks shop D 1 1
chiba starbucks shop A 0 2
tokyo starbucks shop B 2 1
tokyo starbucks shop B 1 0
tokyo starbucks shop C 2 3
tokyo starbucks shop F 1 2
aichi starbucks shop E 1 2
</code></pre>
<p>I could get the gender distribution but not the age range, how can I do this.</p>
<pre><code>SELECT
state,
poi_name,
count(gender) all_cnt,
count( gender = '0' or null) as Unknown,
count( gender = '1' or null) as Total_Male,
count( gender = '2' or null) as Total_Female,
count('gender') OVER(PARTITION BY state) AS cnt_for_state
FROM `geo_data_working.hw0160_infoDemographic`
GROUP BY state,poi_name
ORDER BY state,poi_name

<pre><code>age range:
-1:13-17
1:18-24
2:25-34

74,120,650 | <p>I'm trying to create a todolist with React which when you double click on one of the to do list that will show input that allow you to edit the value. But I want to show the before value in the input edit when user click on it and the user can erase the before value and change to new and change the value.</p>
<p>I know, my explanation is very bad. I will show the example that I want in here <a href="https://todomvc.com/examples/react/#/" rel="nofollow noreferrer">https://todomvc.com/examples/react/#/</a>.
I want to make just like this person todo mvc which when you double click the todolist the edit input value still shown the before value.</p>
<pre><code>import {useState} from 'react';
export default function App() {
const [todo, setTodo] = useState([])
const [input, setInput] = useState('')
const [edit, setEditing]= useState(null)
const [edittext , setEditingText] = useState('')
const InputHandler = (e)=>{
setInput(e.target.value)
}
const SubmitHandler = ()=>{
setTodo([...todo, {text:input, id: Math.random()*1000}])
setInput('')
}
const EditHandler = (e)=>{
setEditingText(e.target.value)
console.log(e.target.value)
}
const SubmitEdit = (id)=>{
setTodo([...todo].map((todos)=>{
if(todos.id === id){
todos.text = edittext
}
return todos
}))
setEditing(null)
setEditingText("")
}
return (
<div className="App">
<input value={input} onChange={InputHandler}/>
<button onClick={SubmitHandler}>Add</button>
{todo.map(todos =>
<div key={todos.id}>
{edit === todos.id ?
(<><input type="text" value={edittext} onChange={EditHandler}/>
<button onClick={()=>SubmitEdit(todos.id)}>Edit</button></>)
: (<p onDoubleClick={()=>setEditing(todos.id)}>{todos.text}</p>)
}
</div>
)}
</div>
);

74,120,684 | <p>I have an issue with adding a point to the existing/old score value after I refresh the web page. Instead of adding a point to the existing/old score, it replaces it, which means if there's an existing/old score already, it will reset and start from 1 again. I don't want that. I want it continues.</p>
<p>Here's my current code, the localStorage code is on the bottom:</p>
<pre><code>function addPhoto(data, mode) {
// DATA
let userName = data.uniqueId;
let userAvatar = data.profilePictureUrl;
let word = ['Nice going','That’s better than ever','That’s first class work','I’m impressed','Nothing can stop you now','Well done','Good job','You did it','That’s the way','You rock','I knew you could do it','Keep up the good work','That’s clever','Way to go','Outstanding','Tremendous','Fantastic','You are amazing','No one can beat you','You are the chosen one'];
let words = word[Math.floor(Math.random()*word.length)];
if (mode == "winner") {
wins[userName] = wins[userName] || 0
wins[userName]++
addContent(
`<div style="text-align:center;font-size: .8rem;">
<div style='padding-bottom:.25rem;color:#1881FF;'> `+ words + `</div>
<div style='padding-bottom:.5rem;font-weight: bold;color:#20B601;'>`+ userName + ` ❗</div>
<div>
<img src="`+ userAvatar + `" style="width:135px;height:135px;border-radius: 30%;border: 1px solid #20B601;box-shadow: 0 0 7px 1px #20B601;"/>
<span style='color:#EA0C0C; font-weight: bold;'>&nbsp;&nbsp;&nbsp;&nbsp;Wins: x`+ wins[userName] + `</span>
</div>
</div>`
);
}
// Set
$("#lastWinner").html(`<div class="lastWinPopUp winnerpopup">
<p>Winner:</p>
</br>`+ userName + `
</br></br><img src="`+ userAvatar + `" style="width:80px;height:80px;border-radius: 10%;box-shadow: 0 0 7px 1px #000000;"/>
</br></br>Win streak:<p id="score"></p>
</div>`
);
//<span style='color:#EA0C0C; font-weight: bold;'>&nbsp;&nbsp;&nbsp;&nbsp;Wins: x`+ wins[userName] + `</span>
// Sound
playSound(3);
const username = userName;
const score = wins[userName];
localStorage.setItem(username, score)
var existing = localStorage.getItem(username);
var data = existing ? existing + score : score;
localStorage.setItem(username, data);
document.getElementById("score").innerHTML = localStorage.getItem(username);
}
</code></pre>
<p>The result from this current code is:</p>
<p>After refreshing the page, it will replace the existing/old score, and start again from 1 point. As you can see I tried adding the <code>var existing</code> an attempt to add a point to the existing/old score.</p>
<p>But instead of adding 1 point, it adds number <code>1</code> literally next to the current value which will become <code>11</code>(becomes 1 because it still replaces the existing/old score), and becomes <code>22</code>, <code>33</code>, and so on as it adds more points.</p>
<p>Could anyone modify the code for me?</p>

74,120,689 | <p>I'm trying to create a functional inheritance hierarchy. We are working with implementing our own priority queue class template, and the program includes lists such as buy orders.</p>
<p>My idea was to have "p_queue" as the base class, and let the "orders" class inherit from it, and then let subclasses such as "buy_orders" inherit from the orders class. My reasoning is that every order in this program is a priority queue, as they will be sorted by it.</p>
<p>Normally I would understand the error "type 'base_class' is not a direct base of 'sub_class'" if the derived class wasn't directly inheriting the superclass. But since the orders class inherits the p_queue class and no other class directly inherits from priority queue class, I'm confused why I get this error message.</p>
<p>Here is the code</p>
<pre><code>//main.cpp
#include "orders.h"
int main(){
return 0;
}
</code></pre>
<pre><code>//orders.h
#include "p_queue.h"
template<typename T>
struct less{
bool operator()(const T& a, const T& b){
return a < b;
}
};
template<typename T>
class Orders : public p_queue<T, decltype(less<T>())> {
private:
size_t m_Size;
std::vector<T> list;
public:
Orders(const size_t& sz, const std::vector<T>& l) : list(l), m_Size(sz),
p_queue<T>(&(*list.begin()), &(*list.end()), less<T>()){}
virtual const size_t getSize() const { return m_Size; }
virtual const std::vector<T> getList() const = 0;
};
struct buy_orders : public Orders<size_t>{
std::vector<size_t> buy_prices;
buy_orders(const size_t& sz) : Orders(sz, buy_prices) {}
};
</code></pre>
<pre><code>//p_queue.h
#include <functional>
template<typename T, typename Compare = std::less<T>>
class p_queue{
protected:
T* m_first;

74,120,694 | <p>I'm building a dynamic list of trees that starts with Oak, Pine, Aspen, Bald Cypress.</p>
<p>Which includes a button to add a 'Redwood' tree to the end of the list, and a 'Pear' tree to the start of the list.</p>
<p>I then included a button that onclick would change the strings to lowercase but I can't seem to get it right. I know the push() method will add the lowercase strings to the end of the list but I can't figure out how to get rid of the old strings with uppercase letters, and it also keeps adding more items to the list when the button is pushed again. I also tried the map method, however it did not seem to work unless created a new variable.</p>

trees.forEach(tree => {

This is just an example. In my geopandas plots I would like to customize, markers, legends, etc. How can I access the relevant matplotlib objects?</p>

# alternatively:
# df.plot(linewidth = 3., color = 'k', markersize = 9, markeredgewidth = 1.5, markerfacecolor = '.75', markeredgecolor = 'k', marker = 'o', markevery = 32)
plt.show()
# create GeoDataFrame from df

74,120,748 | <p>I am trying to find abbreviations in a sentence with python, for example, u.s.a. equals to usa, so I want to find u.s.a. and remove the full stop in this abbreviation and get usa as the result.
'I come from u.s.a..'
Then will become 'I come from usa.'
How to do with it?
Now I can only find all the abbreviations with regex
<code>pattern = re.compile(r'(?:[a-z]\.){2,}')</code>, but cannot just remove the full stop.</p>

74,120,817 | <p>This is kind of a challenge, as I'm sure there must be a better way to do this but I'm not able to find it.</p>
<p>Given a string, I want to split it into two strings by a given index. For instance:</p>
<pre><code>input:
- string: "helloworld"
- index: 5
output: ["hello", "world"]

<p>An easy way is to make two slices, but isn't there a more direct way like splitting by a regex or something? I would like to achieve my purpose with a single instruction.</p>
<p>The non-elegant way:</p>
<pre class="lang-js prettyprint-override"><code>const str = "helloworld";
const [ str1, str2 ] = [ str.substring(0, 5), str.substring(5) ];

</code></pre>
<p>I've found a <a href="https://bugreports.qt.io/browse/QTBUG-83410" rel="nofollow noreferrer">bugreport</a> that is similar to my problem. The reporter provided the minimal code that reproduces the problem:</p>
<pre><code>#include <QCoreApplication>
#include <QJSEngine>
#include <QThread>
#include <QTimer>
int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
QJSEngine engine;
engine.installExtensions(QJSEngine::ConsoleExtension);
engine.evaluate("var iteration = 0;");
auto function = engine.evaluate(R"((
function()
{
if (++iteration % 100 == 0)
console.log(iteration);
}
))");
QThread thread;
thread.start();
QTimer timer;
QObject::connect(&timer, &QTimer::timeout, &engine, [&]{function.call();}, Qt::DirectConnection);
timer.moveToThread(&thread); // Comment it if you want to test QJSEngine in the main thread
QMetaObject::invokeMethod(&timer, "start", Q_ARG(int, 0));
return app.exec();
}
</code></pre>
<p>Doing the same thing in the main thread (thread where <code>QJSEngine</code> was created) does not crash the program.</p>
<p>Could you please tell me how to make <code>QJSEngine</code> thread-safe for this situation? The reported provided template functions <code>safeEngineCall()</code> to wrap engine calls in blocking queue but I can't understand how to use it.</p>
<p>Thanks in advance.</p>
<p><strong>UPD:</strong> I had an idea to wrap <code>QJSValue::call()</code> to a thread-safe function to force it call in the <code>QJSEngine</code>'s object thread by using <code>QMetaObject::invokeMethod()</code>:</p>
<p><strong>threadsafeqjsengine.h</strong></p>
<pre><code>class ThreadSafeQJSEngine : public QObject
{
Q_OBJECT
QJSEngine* m_engine;
public:
ThreadSafeQJSEngine(QObject *parent = Q_NULLPTR);
virtual ~ThreadSafeQJSEngine();
// ...
QJSValue call(QJSValue value, const QJSValueList& args);
// ...
private slots:
inline QJSValue call_imp(QJSValue value, const QJSValueList& args) {
return value.engine() == m_engine ? value.call(args) : QJSValue();
}
// ...
};
</code></pre>
<p><strong>threadsafeqjsengine.cpp</strong></p>
<pre><code>ThreadSafeQJSEngine::ThreadSafeQJSEngine(QObject *parent)
: QObject(parent)
{
m_engine = new QJSEngine;
}
ThreadSafeQJSEngine::~ThreadSafeQJSEngine()
{
delete m_engine;
}
QJSValue ThreadSafeQJSEngine::call(QJSValue value, const QJSValueList &args)
{
if (QThread::currentThread() != this->thread())
{
QJSValue result;
QMetaObject::invokeMethod(this,
"call_imp",
Qt::BlockingQueuedConnection,
Q_RETURN_ARG(QJSValue, result),
Q_ARG(QJSValue, value),
Q_ARG(const QJSValueList&, args)
);
return result;
}
else
{
return call_imp(value, args);
}
}
// ...
</code></pre>
<p><strong>main.cpp</strong></p>
<pre><code>int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
ThreadSafeQJSEngine engine;
// The same as before
// ...
QObject::connect(&timer, &QTimer::timeout, &engine, [&]{engine.call(function);}, Qt::DirectConnection);
// The same as before
// ...
}
</code></pre>
<p>But the problem is not gone and it crashes as usual. What am I doing wrong?</p>

74,120,913 | <p>I am observing some weired issue. I am not sure whether it is lack of my knowledge in spark or what.</p>
<p>I have a dataframe as shown in below code. I create a tempview from it and I am observing that after merge operation, that tempview becomes empty. Not sure why.</p>
<pre><code>val myDf = getEmployeeData()
myDf.createOrReplaceTempView("myView")
// Result1: Below lines display all the records
myDf.show()
spark.Table("myView").show()
// performing merge operation
val sql = s"""MERGE INTO employee AS a
USING myView AS b
ON a.Id = b.Id
WHEN MATCHED THEN UPDATE SET *
WHEN NOT MATCHED THEN INSERT *"""
spark.sql(sql)
// Result2: ISSUE is here. myDf & mvView both are empty
myDf.show()
spark.Table("myView").show()
</code></pre>
<p><strong>Edit</strong></p>
<p>getEmployeeData method performs join between two dataframes and returns the result.</p>
<pre><code>df1.as(df1Alias).join(df2.as(df2Alias), expr(joinString), "inner").filter(finalFilterString).select(s"$df1Alias.*")

74,120,975 | <p>Is there a way to call the constructor of a class, given the pointer-type of that class type as the template parameter?</p>
<pre><code>MyClass<AnotherClass*> => how to call the default constructor of AnotherClass in MyClass?
</code></pre>
<p>This one does obviously not work (doesnt compile), because in <code>GetNew</code> the <code>new T</code> and the return type T don't fit together. What would be needed is some kind of "type dereferencing" to come to the class type, given the pointer type.</p>
<pre><code>class AnotherClass
{};
template <class T>
class MyClass
{
public:
// this does obviously not compile
virtual T GetNew()
{
return new T; // how let T be AnotherClass* and to create an AnotherClass instance here?
}
};
int main()
{
// this does not compile:
MyClass<AnotherClass*> tmp; // here, AnotherClass is **pointer** type
AnotherClass* a = tmp.GetNew();
}
</code></pre>
<p>A workaround would be to use the class type as the template parameter and use poiter types as return types. But this changes the interface, so I would still like a solution to pointer template type.</p>
<pre><code>class AnotherClass
{};
template <class T>
class MyClass2
{
public:
virtual T* GetNew()
{
return new T;
}
};
int main()
{
// this does work:
MyClass2<AnotherClass> tmp2; // here, AnotherClass is **not** pointer type
AnotherClass* b = tmp2.GetNew();
}
</code></pre>
<p>Another workaround could be to use a factory or similar, but I would like to use the default constructor without additional helping structures.</p>

<p>The <code>urlBuilder.Action("PackagesList", "Packages");</code> returns null during the test run. I am trying to fake the <code>UrlHelper</code> class with a fake return value by assigning it to the controller but it doesn't seem to work. Here is the current implementation of my test:</p>
<pre><code>private readonly PackagesController _controller_Packages;
private readonly ILMS_Service _lms_service;

// Fake session
httpContext = A.Fake<HttpContextBase>();
httpResponse = A.Fake<HttpResponseBase>();
httpSession = A.Fake<HttpSessionStateBase>();
urlBuilder = A.Fake<UrlHelper>();
//SUTs
_controller_Packages = new PackagesController(_lms_service, urlHelper);
A.CallTo(() => httpContext.Response).Returns(httpResponse);
A.CallTo(() => httpContext.Session).Returns(httpSession);
}
[TestMethod]
public void should_EditPackageDetails()

// Arrange
int packageID = 1;
string package_name = "Test package";

int unit_count = 10;
string description = "Sample test description";
int expected_statusCode = (int)HttpStatusCode.OK;

var context = new ControllerContext(new RequestContext(httpContext, new RouteData()), _controller_Packages);
_controller_Packages.ControllerContext = context;
A.CallTo(() => urlBuilder.Action("PackagesList", "Packages"))
.Returns("/Packages/PackagesList");
// Act
_ = A.CallTo(() => _lms_service.EditPackageDetails(
A<int>.Ignored,

description
) as JsonResult;
dynamic result = _editPackage.Data;
// Assert
Assert.AreEqual(expected_statusCode, result.statusCode);
Assert.AreEqual(expected_page_destination, result.redirectURL);
}
</code></pre>
<p>With this test, it is still returning null, not <code>"/Packages/PackagesList"</code>. How can I fake <code>UrlHelper</code> with it returning <code>"/Packages/PackagesList"</code> as the value with FakeitEasy? Any help would be appreciated. I have an ASP.NET MVC 4, MSTest, and FakeitEasy mocking framework. Thanks!</p>

<p>On the Jitsi Android docs they have mentioned this way <strong>but this does not imports Jitsi Android SDK to our project.</strong></p>

<p>Instead, we used to get a warning like this below while syncing the Gradle files.

string2 = "CDGIKNOP"

<p>Whenever I try to save the result into some variable, it simply stores a <code>None</code> value. Even though I tried storing the result in a text file, that also didn't work.</p>

74,121,186 | <p>For some reason Finder on Mac doesn't come with create new file functionality. The fastest way I've found to create a new file is to drag the finder path into Terminal and create a file there... which is super annoying</p>
<p>I wrote an apple script to automatically create a new file and bound it to a shortcut. It works perfectly, except that I can't figure out how to <em>open</em> the new file from within the applescript. I'm pretty sure the error stems from POSIX / UNIX paths but couldn't find a way to get this to work even when I put POSIX next to file, currentDir etc.</p>
<p>Here's my script:</p>
<pre><code>set file_name to display dialog "File Name" default answer "untitled" with icon note buttons {"Cancel", "Continue"} default button "Continue"
set file_name to (text returned of file_name)
tell application "Finder"
set theWin to window 1
set currentDir to POSIX path of (target of theWin as alias)
make new file at (the target of the front window) as alias with properties {name:file_name}
set currentPath to (currentDir & file_name) as string
open file currentPath
end tell
</code></pre>
<p>The script creates the file, then errors out saying it can't find the file to open it.</p>

74,121,235 | <p>I am new to Django and my current task is to upload a xml file with 16 fields and more than 60000 rows to a database in PostgreSQL. I used Django to connect to the Database and was able to create a table in the database.
I also used XML Etree to parse the xml file. I am having trouble storing the data in the table that I created in the sql database.</p>
<p>This is the code that I used to parse:</p>
<pre><code>import xml.etree.ElementTree as ET
def saveXML2db():
my_file = "C:/Users/Adithyas/myproject/scripts/supplier_lookup.xml"
tree = ET.parse(my_file)
root = tree.getroot()
cols = ["organization", "code", "name"]
rows = []
for i in root:
organization = i.find("organization").text
code = i.find("code").text
name = i.find("name").text
x = rows.append([organization, code, name])
data = """INSERT INTO records(organization,code,name) VALUES(%s,%s,%s)"""
x.save()
saveXML2db()
</code></pre>
<p>the code runs without any error, but I am unable to store the data into the table in the SQL database.</p>

<p>It works for names without middle names. But I need this to work for names with middle names too. When I try to concat <code>middleName</code>, I get an error because the path <code>middleName</code> does not exist on all documents. I could not implement <code>$cond</code> and <code>$exists</code> operators properly make this work. Any kind of help is highly appreciated. Thanks!</p>

1 2022-10-13 two 77123
2 2022-10-13 three 451

<p>The data for reasons <strong>one</strong> and <strong>three</strong> needs to be scaled by 100 as it is stored in a minimized way on the database.</p>
<p>Is there a way to traverse the cells and add '00' to the counts or multiply by 100 where reason is not equal to two? And end up with something like this:</p>
<pre><code> date reason count
0 2022-10-13 one 12300
1 2022-10-13 two 77123
2 2022-10-13 three 45100
3 2022-10-13 three 7700

74,121,290 | <p>I have the following scenario:</p>
<ul>
<li>An organization has an internal application, X, which is registered under the 'main' tenant, allowing employees to utilize it.</li>
<li>App X has an API exposed for other applications (which are also registered under the main organization tenant) to used, and thus, this is all setup in AD.</li>
<li>A new B2C tenant has been created, where another public facing application, Y, will be registered.</li>
</ul>
<p>How do I allow my App Registration for Y in my B2C tenant to use the exposed API of X?</p>
<p>Any feedback would be appreciated.</p>
<p><strong>Edit 1:</strong></p>
<p>I'm assuming I'd need to setup a <a href="https://learn.microsoft.com/en-us/azure/active-directory/develop/authentication-flows-app-scenarios#daemon-app-that-calls-a-web-api-in-the-daemons-name" rel="nofollow noreferrer">Daemon auth flow</a>, as the backend of Y will be authenticating with X as the app itself, and not as or on behalf of the user logged into Y.</p>
<p><strong>Edit 2:</strong></p>
<p>After some looking into this today, I'm considering creating an AD App Registration for Y in the main organization of X, allowing me to set up any connections that need to be made there, and I'd update the backend of Y to make a call as a Daemon to X, passing all the relevant information and client secret.</p>
<p>Seems a bit unusual, so will look for alternatives, but would also appreciate some feedback from someone who has more experience :)</p>
<p><strong>Edit 3:</strong></p>
<p>To clarify, I am looking to facilitate the communication between <em>backend</em> applications between two tenants, where one is a B2C tenant, and the other is an internal organization tenant.</p>

74,121,308 | <p>I am delivering data from PLC Siemens S7 through node-red installed on IoT edge device to the cloud storage.</p>
<p>In the node-red I receive data as a JSON object with several properties every second from PLC node. The JSON object (or data) has the same properties every second.</p>
<p>Some properties change every second, some change in five minute, some remain constant for several hours.</p>
<p>To handle data to the cloud the JSON object is handled to the IoT hub node in the node-red.</p>
<p>I would like to process this JSON object before handling to the IoT hub node in a way that the JSON object has only the properties which changed from previous state (a second ago). It means that I want to compare an input object at the moment <code>t</code> with the object at <code>t-1</code> and generate a new object with properties of the object at <code>t</code> which differ from those of the object at <code>t-1</code>.</p>
<p>The new object will be handled further. The object processing is expected to be done in the function node in the node-red. From PLC node the JSON object is received as the <code>msg.payload</code>.</p>
<p>Could you please help me to script in (javascript) the process I have described?</p>
<p>msg.payload to the function node is json object:</p>
<pre><code>{"Zone0": 200,
"Wire_tension": 2.5}
</code></pre>
<p>UPD: Since it was not clear what I have tried, here is the code. Sorry for not providing it, I thought it was clear.</p>
<pre><code>var state = {}; // this state will be messaged further
var prev_state = {
"Zone0": 0,
"Wire_tension": 0
}; // initially zeros are assigned
var current_state = msg.payload; // has these two properties and updated every second
// comparison of properties
if (current_state.Zone0 != prev_state.Zone0) {
state["Zone0"] = current_state.Zone0;
prev_state["Zone0"] = current_state.Zone0;
}
if (current_state.Wire_tension != prev_state.Wire_tension) {
state["Wire_tension"] = current_state.Wire_tension;
prev_state["Wire_tension"] = current_state.Wire_tension;
}
msg.payload = state;
return msg;
</code></pre>
<p>It looks like when the flow in the node-red starts the function node runs the code every time. Therefore prev_state is assigned every time. I understand that I need to somehow handle initial state which is updated further.</p>
<p>UPD2:
I also tried using the following code (also with <em>context</em> feature). The example is with my real data:</p>
<pre><code>var state = {}; // this state will be messaged further
flow.set(["Zone0", "Wire_tension"],[0,0]); // initially zeros are assigned
var current_state = msg.payload; // has these two properties and updated every second
// comparison of properties
if (current_state.Zone0 != flow.get("Zone0")) {
state["Zone0"] = current_state.Zone0;
flow.set("Zone0", current_state.Zone0);
}
if (current_state.Wire_tension != flow.get("Wire_tension")) {
state["Wire_tension"] = current_state.Wire_tension;
flow.set("Wire_tension", current_state.Wire_tension);
}
msg.payload = state;
return msg;

74,121,374 | <p>Is it possible to use CSS grid to auto-fit the columns in a row to always take up the whole width?</p>

list_names = ['Richard White', 'Susan Pierce', 'Kim Note', 'John Lee', 'Jennifer Six', 'Maria Cruz', 'Martin Lewis']
list_grades = ['100', '46', '76', '74', '50', '67', '79']
</code></pre>
<p>What I'd like to receive as a result:</p>
<pre><code>list_final = ['55900 Richard White 100', '44560 Susan Pierce 46', '49510 Kim Note 76', '49509 John Lee 74', '49519 Jennifer Six 50', '49556 Maria Cruz 67', '49586 Martin Lewis 79']

74,121,466 | <p>For typing practice purpose, I'm trying to apply the following typing to get the first element of an array :</p>
<pre><code>type First<T extends unknown[]> = T extends [infer P, ...unknown[]] ? P : never
</code></pre>
<p>I have the following implementation :</p>
<pre><code>const getFirstOrThrow = <T extends unknown[]>(arr: T): First<T> => {
if(arr.length === 0) {
throw new Error("Empty array")
}
return arr[0]; // Type 'unknown' is not assignable to type 'First<T>'.(2322)
}
</code></pre>
<p>For some reason typescript is not able to understand that the array should have at least 1 element.</p>
<p>I tried with the following type too :</p>
<pre><code>type First<T extends unknown[]> = T["length"] extends 0 ? never : T[0];
type A = First<[]> // never
type B = First<[1]> // 1
type C = First<[1,2]> // 1
</code></pre>
<p>Is something like this possible with typescript ?</p>
<p>This typing seems ok to me :</p>
<pre><code>declare function getFirst <T extends unknown[]>(arr: T): First<T>;
const A = getFirst([]) // never
const B = getFirst([1]) // number
const C = getFirst([1, 2]) //number

<p>so i type a script to convert this file into JSON:</p>
<pre><code>import json

fields =['name', 'date', 'time', 'info']
with open(filename) as fh:
l = 1
for line in fh:
description = list( line.strip().split("|", 4))
print(description)
sno ='name'+str(l)
i = 0
dict2 = {}
while i<len(fields):
dict2[fields[i]]= description[i]
i = i + 1
dict1[sno]= dict2
l = l + 1
out_file = open("json_file.json", "w")
json.dump(dict1, out_file, indent = 4)
out_file.close()
</code></pre>
<p>and output looks like this:</p>
<pre><code>{
"name1": {
"name": "red",
"date": "2022-09-29",

This script should now be started several times in the Linux terminal at the same time. Does this work with a normal script without multithreading or _threads or do I need something like this? If yes, which library do you recommend?</p>

74,121,537 | <p>I have a strange json, which:</p>
<ul>
<li>I can not change it, it is from a third party</li>
<li>It can have up to 75 properties</li>
</ul>
<p>A simple example of the json:</p>
<pre class="lang-json prettyprint-override"><code>{
"bookingcode":["ABC","DEF", "GHJ", "TEST"],
"referencenumber":[123, 456]
"bookingdate":["22-07-2022T14:00:30", "23-11-2022T17:00:25"]
}
</code></pre>
<p>I am only interested in the last value of the array and want to deserialize into a class called Booking, so in this case <code>bookingcode="TEST"</code> and <code>bookingdate="23-11-2022T17:00:25"</code>.</p>
<p>A solution would be define a model:</p>
<pre><code>public class Booking
{
public string BookingCode { get; set; }
public int ReferenceNumber { get; set; }
public DateTime BookingDate { get; set;}
}
public class BookingInput
{
public List<string> BookingCode { get; set;}
public List<int> ReferenceNumber { get; set; }
public List<DateTime> BookingDate { get; set; }
}
var bookinginput = JsonSerializer.Deserialize<BookingInput>(jsonString);
var booking = new Booking
{
BookingCode = bookinginput.BookingCode.Last(),
ReferenceNumber = bookinginput.ReferenceNumber.Last(),
...
}
</code></pre>
<p>I think it is very tedious to write out all 75 properties in code like this. Is there a better solution in Json.net or System.Text.Json for this?</p>

<p>i need to pass 1075 to backend api, that is mean i need the number.</p>
<p>How can I do that?</p>

74,121,636 | <p>I need to convert a CSV document to another one in XML format.
This is what I have in my CSV file:</p>
<p>level;1;2;49;50;51;
Position;8455;8930;9405;9880;10355;11015;11490;11965;12440;12915;13575;14050;14525;15000</p>
<p>So, for each level, I should have the same positions described in the field Position
The output format should be like that:</p>
<p><a href="https://i.stack.imgur.com/KxRgA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KxRgA.png" alt="Code description" /></a></p>
<p>And so on..until I fill all values from the Position table
How can this be achived?
Any example?
Thanks.</p>

74,121,671 | <p>For my master thesis i downloaded a ton of finance related files. my objective is to find a specific set of words ("chapter 11") to flag all companies that have gone through the debt restructuring process.
The problem is that i have more than 1.2 milion little files that makes the search really inefficient. For now i wrote very basic code and i reached a velocity of 1000 documents every 40-50 seconds. i was wondering if there are some specific libraries or methods (or even programming languages) to search even faster. this is the function i'm using so far</p>
<pre><code>def get_items(m):
word = "chapter 11"
f = open(m, encoding='utf8')
document = f.read()
f.close()
return (word in document.lower())
# apply the function to the list of names:
l_v1 = list(map(get_items,filenames))
</code></pre>
<p>the size of the files varies between 5 and 4000 KB</p>

74,121,675 | <p>I want to navigate through my ListView only with two buttons, not with the fingers and scroll so: <code> physics: const NeverScrollableScrollPhysics(),</code>.
here is a picture, the problem is below:</p>
<p><a href="https://i.stack.imgur.com/Dl2sV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Dl2sV.png" alt="enter image description here" /></a></p>
<p>when I open the keyboard, it looks like this: <a href="https://i.stack.imgur.com/Ozqls.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ozqls.png" alt="enter image description here" /></a></p>
<p>So my Input Fields are obscured behind the keyboard. With an active scroll physics, this wouldn't happen because it resizes the screen so that it fit. Is there a way to move the End of my scaffold to the end of the keyboard, e.g.? Or a workaround like to activate the scrolls physics only when the keyboard appears?
I also have a</p>
<pre><code> ScrollConfiguration(
behavior: MyBehavior(),
class MyBehavior extends ScrollBehavior {
@override
Widget buildOverscrollIndicator(
BuildContext context, Widget child, ScrollableDetails details) {
return child;
}
}
</code></pre>
<p>but I think this is not important for my problem</p>

74,121,693 | <p>I have a dataset of NYC taxi data that I am trying to filter through. The dataset has the schema like this:</p>
<pre class="lang-none prettyprint-override"><code>root
|-- medallion: string (nullable = true)
|-- hack_license: string (nullable = true)
|-- vendor_id: string (nullable = true)
|-- rate_code: integer (nullable = true)
|-- store_and_fwd_flag: string (nullable = true)
|-- pickup_datetime: timestamp (nullable = true)
|-- dropoff_datetime: timestamp (nullable = true)
|-- passenger_count: integer (nullable = true)
|-- trip_time_in_secs: integer (nullable = true)
|-- trip_distance: double (nullable = true)
|-- pickup_longitude: double (nullable = true)
|-- pickup_latitude: double (nullable = true)
|-- dropoff_longitude: double (nullable = true)
|-- dropoff_latitude: double (nullable = true)
</code></pre>
<p>I want to filter the dataset so that any entries which have pickup and dropoff times not between the hours of 9am to 5pm are excluded. But I am having trouble writing a helper method to use within a <code>withColumn</code> function. Here is what I have for the <code>withColumn</code> calls:</p>
<pre class="lang-py prettyprint-override"><code>from pyspark.sql.window import Window
from pyspark.sql import functions as fun
taxi_raw.withColumn("pickup_datetime", remove_pickup_times(fun.col("pickup_datetime"))
taxi_raw.withColumn("dropoff_datetime", remove_dropoff_times(fun.col("dropoff_datetime"))
</code></pre>
<p>And here is what I have for the helper methods so far:</p>
<pre class="lang-py prettyprint-override"><code>import datetime
def remove_pickup_times(pickup_datetime):
time_start = datetime.time(9,0,0)
time_end = datetime.time(17,0,0)
if(pickup_datetime.time() >= time_start and pickup_datetime.time() <= time_end):
//insert code to remove entry from dataset
def remove_dropoff_times(dropoff_datetime):
time_start = datetime.time(9,0,0)
time_end = datetime.time(17,0,0)
if(dropoff_datetime.time() >= time_start and dropoff_datetime.time() <= time_end):
//insert code to remove entry from dataset

74,121,696 | <p>I have a project in C# language. which should take the name of a folder and a file. If the file does not exist in the folder, <code>the file not exist</code> will be printed. If there is a file, based on the file creation date, determine how many files have a creation date smaller than this file.
My code is as follows:</p>
<ol>
<li><p>First, it is checked if the file does not exist in the folder, <code>the file not exist</code> is printed</p>
<pre><code>DirectoryInfo dir = new DirectoryInfo(@"c:\mydirectory");
string fileName = "myfile.png";
FileInfo[] files = dir.GetFiles("*.*");
Boolean fileFound = false;
for(int i=0; i<files.Length; i++)
{
if(files[i].Name == fileName)
{
fileFound = true;
break;
}
}
if(fileFound==false)
{
Console.WriteLine("the file not exist");
return;
}
</code></pre>
</li>
</ol>
<ol start="2">
<li><p>The files are then sorted by creation date:</p>
<pre><code> for (int i = 0; i < files.Length; i++)
{
for (int n = i; n < files.Length; n++)
{
if (files[n].CreationTime < files[i].CreationTime)
{
var temp = files[i];
files[i] = files[n];
files[n] = temp;
}
}
}
</code></pre>
</li>
</ol>
<p>3.Finally, I find the index of the file in the list and it is printed:</p>
<pre><code> for (int i = 0; i < files.Length; i++)
{
if (files[i].Name == fileName)
{
Console.WriteLine("index of this file is: " +i);
break;
}
}
</code></pre>
<p>My project works fine, but I think there must be an easier way with fewer lines. Can anyone guide me?</p>

74,121,748 | <p>I have some struggles with assigning a type to filter function with TypeScript.
So, when I'm building the app, it says like:</p>
<blockquote>
<p>Parameter 'item' implicitly has an 'any' type.</p>
</blockquote>
<p>And function looks like:</p>
<pre><code>allowedProductPaymentMethods?.filter(item => item.id !== paymentItem.id && item.balance > 0)
</code></pre>
<p>So I tried adding like <code>(item: any)</code>, but it's not recognizing the typing. Any ideas how to fix it?</p>
