74,324,633 | <p><strong>TL;DR: I try to generate large amounts of random numbers from a set of <code>[-1, 1]</code> I found out that <code>np.random.Generator.choice</code> is the worst method while the best one is to use <code>np.random.Generator.random</code> and move from boolean and to integer. Is there a better way to generate such random numbers in large amounts?</strong></p>
<p>I want to simulate the motion of <code>m</code> particles in a closed container with reflective surfaces in d-D in a mesh for <code>n</code> iterations. There is also a hitting condition that I check after every iteration. Without loss of generality, let's assume <code>d=2</code>.</p>
<p>Since I use a mesh, the movement part boils down to generating -1s and +1s. At this point, I treat each particle individually in a loop so after generating these -1s and +1s, I access them in a loop and as the number of particles still in the system decreases, I generate less numbers. This part can be improved and I am open to comments but it is not what I am asking.</p>
<p>My question is <strong>what the fastest way is to generate many random numbers from the set <code>[-1,1]</code>.</strong> I thought of five approaches, four with np and with random.</p>
<p>I firstly thought that the obvious choice was <code>np.random.Generator.choice([-1,1],size=(m,2))</code>. It took 595.6 seconds.</p>
<pre class="lang-py prettyprint-override"><code>n=int(5e6)
m=1000
rng=np.random.default_rng()
tic=time.time()
for i in range(n):
a=rng.choice([-1,1], size=(m,2))
for j in range(m): #This useless loop is here to demonstrate that I am accessing each line one by one
b=a[j]
print("choice",time.time()-tic)
</code></pre>
<p>I tried to move from uniform~[0,1) to integers -1 and +1 with code below, which took 527.6 s. Note that the +0 part converts <code>True</code> to <code>1</code> and <code>False</code> to <code>0</code>.</p>
<pre class="lang-py prettyprint-override"><code>n=int(5e6)
m=1000
rng=np.random.default_rng()
tic=time.time()
for i in range(n):
a=(rng.random(size=(m,2))>0.5+0)*2-1
for j in range(m):
b=a[j]
print("operate",time.time()-tic)
</code></pre>
<p>I tried something very similar with <code>np.sign</code>, which took 543.5 s.</p>
<pre class="lang-py prettyprint-override"><code>n=int(5e6)
m=1000
rng=np.random.default_rng()
tic=time.time()
for i in range(n):
a=np.sign(rng.random(size=(m,2))-0.5)
for j in range(m):
b=a[j]
print("sign",time.time()-tic)
</code></pre>
<p>Finally, I tried <code>np.random.Generator.integers</code> with a few extra manipulations. It took 553.8 s.</p>
<pre class="lang-py prettyprint-override"><code>n=int(5e6)
m=1000
rng=np.random.default_rng()
tic=time.time()
for i in range(n):
a=(rng.integers(2,size=(m,2))*2)-1
for j in range(m):
b=a[j]
print("integer",time.time()-tic
</code></pre>
<p>Since I access them one by one, I could also use the <code>random.random()</code> on the spot. It takes far too long (~750 s).</p>
<p>What baffles me most is that <code>rng.choice()</code> is by far the worst choice. I knew that it didn't work well for small set size, but since <code>m</code> is large, I thought it can redeem itself. I am also surprised that boolean to integer transition offers the fastest solution.</p>
<p>So, my question is, what is the fastest way to generate <code>m*d</code> random integers belonging to the set <code>[-1,1]</code>? Is it one of those that I tried or am I missing something? Or am I not even on the right track?</p>

74,324,645 | <p>I have a dataset where I will be using the FILTER formula to extract specific values relative to an individual. For each individual, I only want to be extracting the last 2 scores. The data is in descending chronological order so effectively I just need the first 2 entries that exist.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Year</th>
<th>Name</th>
<th>Score</th>
</tr>
</thead>
<tbody>
<tr>
<td>2022</td>
<td>A</td>
<td>50</td>
</tr>
<tr>
<td>2022</td>
<td>B</td>
<td>40</td>
</tr>
<tr>
<td>2022</td>
<td>C</td>
<td>60</td>
</tr>
<tr>
<td>2021</td>
<td>A</td>
<td>10</td>
</tr>
<tr>
<td>2021</td>
<td>B</td>
<td>5</td>
</tr>
<tr>
<td>2020</td>
<td>A</td>
<td>90</td>
</tr>
<tr>
<td>2020</td>
<td>B</td>
<td>76</td>
</tr>
<tr>
<td>2019</td>
<td>A</td>
<td>45</td>

<tr>
<td>2019</td>
<td>C</td>
<td>12</td>

<tr>
<td>2018</td>
<td>A</td>
<td>14</td>

<tr>
<td>2017</td>
<td>A</td>
<td>13</td>
</tr>
</tbody>
</table>
</div>
<p>Using a dataset similar to the one attached, if I wasn't interested in only the last 2 scores, I would use something like</p>
<p><code>=FILTER(A:C,B:B=B1)</code> <code>B1</code> for <code>A</code>, <code>B2</code> for <code>B</code> etc.</p>
<p>But doing that would give me <code>6</code> rows for <code>A</code>, <code>3</code> for <code>B</code> and <code>2</code> for <code>C</code>. To standardize this, I only want to consider, at max, <code>2</code> results per individual. How do I change the FILTER formula to achieve this?</p>

74,324,660 | <p>I thought I understood this, but clearly I don't.</p>
<p>I have a context manager that wraps suites of code inside some metadata handling. The details of that don't matter, suffice to say the code needs to be between a push_job() and pop_job(). That all works, so I can say:</p>
<pre><code>with JobManager(*config) as job:
<Processing Goes Here>
<Follow up processing, not connected to the job>
</code></pre>
<p>I thought it would be neat if, instead of inserting the <code>with</code> statement when an entire function needed to be in its own job context, I could just use the same class as a decorator, and say:</p>
<pre><code>@JobManager
def process_job(job, *other_args, *other_kwargs):
</code></pre>
<p>But it's not working as a decorator, and I can't see why. I get confusion of arguments between the decorator and the wrapped function.</p>
<p>Here's the code:</p>
<pre><code>class JobManager(ContextDecorator, AbstractContextManager):
"""Convenience class that provides both a context manager to surround code
suites needing a new job frame (using push_job()/pop_job()), and a
decorator to wrap functions in the current frame automagically
"""
def __init__(self, *args, **kwargs):
self._func, self._args = (
(args[0], args[1:] if len(args) > 1 else [])
if args and callable(args[0])
else (None, args)
)
self._kwargs = kwargs
def __call__(self, func):
"""Called when using JobManager as a decorator. Returns a new frame."""
@wraps(func)
def inner(*args, **kwargs):
with self._recreate_cm() as job_:
return func(job_, *args, **kwargs)
return inner
def __enter__(self):
"""Called when using JobManager as a context manager. Pushes a new
frame or creates the initial frame from the arguments.
"""
return (
push_job(*(self._args), **(self._kwargs))
if not _jobs else
push_job()
)
def __exit__(self, exc_type, exc_value, traceback):
"""Called when using JobManager as a context manager."""
pop_job()
return super().__exit__(exc_type, exc_value, traceback)

74,324,665 | <p>I have a program to update vehicle inventory. I call the updateVehicle()...it should loop through the arrayList of vehicles to look for a match based on what the user input. In the if statement, if a match is found, update the vehicle in the arrayList with what the user input, display the updated details, display a successfully updated message. If a match was not found, just display not found message.
The code works and will update the vehicle with the correct message if there is only one vehicle in the arrayList. However, if there is more than one vehicle in the arrayList, it will update it, but still prints both messages.</p>
<pre><code>public void updateVehicle(String makeCurrent, String modelCurrent, String colorCurrent, int yearCurrent, int mileageCurrent,
String makeUpdated, String modelUpdated, String colorUpdated, int yearUpdated, int mileageUpdated) {
for (int i = 0; i < listOfVehicles.size(); i++) {
AutoInv vehicle = listOfVehicles.get(i);
if (vehicle.getMake().equalsIgnoreCase(makeCurrent) && vehicle.getModel().equalsIgnoreCase(modelCurrent)
&& vehicle.getColor().equalsIgnoreCase(colorCurrent) && vehicle.getYear() == yearCurrent
&& vehicle.getMileage() == mileageCurrent) {
vehicle.setMake(makeUpdated);
vehicle.setModel(modelUpdated);
vehicle.setColor(colorUpdated);
vehicle.setYear(yearUpdated);
vehicle.setMileage(mileageUpdated);
System.out.println("\nVehicle updated successfully!\n");
displayCurrentVehicleEntry();
// break;
}

System.out.println("\nVehicle not found in inventory!");

<p><code>result</code> is an enum where:</p>
<ul>
<li>0 = white victory</li>
<li>1 = black victory</li>
<li>2 = draw by agreement</li>
<li>3 = draw by stalemate</li>
<li>4 = draw by repetition</li>
<li>5 = draw by fifty move rule</li>
<li>6 = aborted</li>
</ul>
<p>I would like to sort players by maximum number of victories and draws to display a leader board. Is there any straightforward way to get this leader board view or are any changes required in the way the data is organized?</p>

74,324,763 | <p>I'm starting to learn how to use git and I'm very doubful with some questions about security.</p>
<p>I need to manage my codes (in the same GitHub account) between my personal computer and my computer from work, so I've installed git on both. When I clone my repository (personal or private), make changes to it, and push it back, it accepts the pushing without any verification of who is pushing it.</p>
<p>So my question is: How does git know who is pushing to my GitHub repository? If anyone uses "git clone <a href="https://github.com/username/myrepo.git%22" rel="nofollow noreferrer">https://github.com/username/myrepo.git"</a>, will them be able to push to it? How can I avoid that?</p>
<p>I read in other posts that is not possible, but I still don't understand in what step git verifies who is pushing.</p>

74,324,785 | <p>I have two datasets, one has old data and one has updated data. I'd like to create a new dataset by updating values based on if the area, date and column values match.</p>
<p><strong>Data</strong></p>
<p>df1</p>
<pre><code>area date aa bb cc
japan 10/1/2027 1 0 0
us 1/1/2022 5 5 5
fiji 11/2/2026 1 1 1
</code></pre>
<p>df2</p>
<pre><code>area date aa bb cc stat
japan 10/1/2027 0 5 5 yes
fiji 11/2/2026 0 0 10 no
</code></pre>
<p>I have two datasets. I wish to <strong>replace the values in [aa], [bb], and [cc] columns of df2 with the updated values from df1 if we have the same date and area values</strong>. The aa, bb, and cc column are replaced with the updated values.</p>
<p><strong>Desired</strong></p>
<pre><code>area date aa bb cc stat
japan 10/1/2027 1 0 0 yes
fiji 11/2/2026 1 1 1 no
</code></pre>
<p><strong>Doing</strong></p>
<pre><code>df['date'] = df.date.apply(lambda x: np.nan if x == ' ' else x)
</code></pre>
<p>I am not exactly sure how to set this up, however, I have an idea. Any suggestion is appreciated</p>

AWS support had captured the network packets, no issues were found.</p>

74,324,797 | <p>I have several thousand lines of code that all ultimately results in a few strings being printed using <code>print()</code> calls. Is there a way to, at the bottom of my code, export everything that has been printed to a text file?</p>

74,324,808 | <p>After being helped by other users’ questions uncountable times, I finally have to ask my first question.</p>
<p><strong>What I’m trying to do:</strong><br>
Running a CodeIgniter project (ver. 4.2.8) on a live server.</p>
<p><strong>Problem:</strong><br>
The URL routing is not working (400 Bad Request error).
It’s a fresh installation, so there are no pages other than the default CodeIgniter homepage (the one that says “Welcome to CodeIgniter”).</p>
<p>The welcome page displays correctly when I access it like this:</p>
<p><a href="http://www.example.com" rel="nofollow noreferrer">www.example.com</a><br>
<a href="http://www.example.com/index.php" rel="nofollow noreferrer">www.example.com/index.php</a></p>
<p>I get the Bad Request error when I try:</p>
<p><a href="http://www.example.com/home" rel="nofollow noreferrer">www.example.com/home</a></p>
<p><strong>Here's what I've done:</strong></p>
<p>Folder structure on server:<br></p>
<pre><code>root
|
+ | dir public_html
| |
+ | dir www.example.com //web root, this is where I put the files that were in the CI public folder
+ | dir exampleCI4 //here I put all the other CI files and folders app, vendor, writable...
</code></pre>
<p>I have adjusted following files:</p>
<ul>
<li>exampleCI4/app/Config/App.php</li>
</ul>
<pre><code>public $baseURL = 'http://www.example.com'
</code></pre>
<ul>
<li><a href="http://www.example.com/index.php" rel="nofollow noreferrer">www.example.com/index.php</a></li>
</ul>
<pre><code>// Load our paths config file
// This is the line that might need to be changed, depending on your folder structure.
require FCPATH . '../exampleCI4/app/Config/Paths.php';
// ^^^ Change this line if you move your application folder
</code></pre>
<p>At first I always got a 500 Internal Server error. After hours of searching for solutions I came across this post:</p>
<p><a href="https://stackoverflow.com/questions/65849139/codeigniter4-htaccess-file-wont-work-with-options-all-indexes">CodeIgniter4 htaccess won't work with Options All -Indexes</a></p>
<p>That indeed did solve the 500 Internal Server error, and the welcome page is displaying. I also confirmed with my hosting provider and it turns out that they don't allow Options All and FollowSymlinks.</p>
<p>I'm pretty sure there is something in the htaccess file that needs to be adjusted but I don't know what.</p>
<p>Here's the complete htaccess file:</p>
<ul>
<li>public_html/www.example.com/.htaccess</li>
</ul>
<pre><code>#Disable directory browsing
Options -Indexes
# ----------------------------------------------------------------------
# Rewrite engine
# ----------------------------------------------------------------------
# Turning on the rewrite engine is necessary for the following rules and features.
# FollowSymLinks must be enabled for this to work.
<IfModule mod_rewrite.c>
# Options +FollowSymlinks
Options +SymLinksIfOwnerMatch
RewriteEngine On
# If you installed CodeIgniter in a subfolder, you will need to
# change the following line to match the subfolder you need.
# http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritebase
# RewriteBase /
# Redirect Trailing Slashes...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Rewrite "www.example.com -> example.com"
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]
# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to the front controller, index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\s\S]*)$ ../index.php/$1 [L,NC,QSA]
# Ensure Authorization header is passed along
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
ErrorDocument 404 index.php
</IfModule>
# Disable server signature start
ServerSignature Off
# Disable server signature end
</code></pre>
<p>If somebody could tell me what needs to be changed in order for it to work, that would be awesome.</p>

74,324,812 | <p>I have an angular application that uses two libraries locally, however, when trying to build everything ending up with an error of modules not found, but I thought it was some problems of undeclared dependencies, or imported, but everything is fine.</p>
<p>For better understanding, I have: Two local libraries that are used by a test application, where this application consumes both libs, but in the compilation it presents the error of modules not found:</p>
<p>`Error: Module not found: Error: Can't resolve '@ngx-formly/example-kendo' in 'C:\SamuelPierre\Example\Repositório\NgBibliotecas\NgBibliotecas\projects\framework-example\src\app\shared'</p>
<p>Error: projects/framework-example/src/app/app.component.ts:1:34 - error TS2307: Cannot find module '@example-library/identity' or its corresponding type declarations.</p>
<p>1 import { UserTokenService } from '@example-library/identity';
~~~~~~~~~~~~~~~~~~~~~~~`</p>
<p>This error appears for all dependencies, but my main file has all the necessary imports and declarations.</p>
<p>Also, "npm install" to install the libraries doesn't help as they are accessed locally. I've already cleaned the node modules, reinstalled npm, everything is ok, but the problem persists.</p>

74,324,853 | <p>This is what I see in an official tool, and I need to calculate the same end value:</p>
<p><a href="https://i.stack.imgur.com/MOOF0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MOOF0.png" alt="enter image description here" /></a></p>
<p>For clarification:</p>
<p>I am given the numbers 95, 3, 5, 19 and 17.15.</p>
<p>I am trying to replicate a math formula in VB.NET in order to achieve the same sum as a government financial tool that I must stay conform with.</p>
<p>The official tool's result and mine differ by 0.1 €, and I don't see what I need to do to achieve the same result.</p>
<p>The official tool states:</p>
<pre><code>A product costs 95.00 € net.
Somebody buys 3 pieces of it.
He gets a discount of 5 % (=4.75 €)
19% VAT is added: 17.15 €
The net price is then 90.25 €
The price is now 270.75 €
The resulting end price is now 322.19 €.
</code></pre>
<p>The values that I am given are these:</p>
<pre><code>net price for 1 piece: 95 €
amount: 3
discount per piece: 5%
VAT amount: 19%
VAT: 17.15
</code></pre>
<p>First, I calculate the discount like this:</p>
<pre><code>Dim amount As Integer = 3
Dim discount As Double = 5
Dim VAT As Double = 17.15
All result As Decimal
Discount = (amount * discount) / 100 = 4.75
Discounted net price per piece = 95 - 4.75 = 90.25
Discounted net price per piece plus vat = 95 + 17.15 = 107.4
Total price result = discounted net price per piece * amount = 107.4 * 3 = 322.2 €

<p>Is there anything that I'm doing wrong by choosing a wrong operator?</p>
<p>Is it even possible to get the same amount as they do with the information that I am given?</p>
<p>Thank you.</p>

74,324,862 | <p>I am pretty new to JS so please go easy on me.</p>
<p>Im trying to increment a value in a JSON file in my JS backend application. Whenever I increment the associated value by the key, it creates a new section "undefined"</p>
<p>Here is the entire application:</p>
<pre><code>const { response } = require("express");
const express = require("express");
const fs = require("fs").promises;
const path = require("path");
const app = express();
const dataFile = path.join(__dirname, "data.json");
//support POSTing form data wuth url encoded
app.use(express.json());
app.get("/poll", async (req, res) =>{
//data is now the js object of the Json data json
let data = JSON.parse(await fs.readFile(dataFile, "utf-8"));
const totalVotes = Object.values(data).reduce((total, n) => total +=n, 0);
data = Object.entries(data).map(([label, votes]) => {
return{
label,
percentage: (((100 * votes) / totalVotes) || 0).toFixed(0) // or with 0 in the even that you divide by zero
}
});
res.json(data);
});
app.use(express.urlencoded({ extended: true}));
app.post("/poll", async (req, res) => {
const data = JSON.parse(await fs.readFile(dataFile, "utf-8"));
data[req.body.add]++;
await fs.writeFile(dataFile, JSON.stringify(data));
res.json(data);
});
app.listen(3000, () => console.log("Server is running ..."));
</code></pre>
<p>Here is my JSON file before I POST</p>
<pre><code>{
"JavaScript":0,
"TypScript":10,
"Both":3}
</code></pre>
<p>Here is a picture of my POST request in Insomnia:
<a href="https://i.stack.imgur.com/LR2rC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LR2rC.png" alt="Insomnia Screenshot" /></a></p>
<p>Here is my JSON file after a Post Requests</p>
<pre><code>{
"JavaScript": 0,
"TypScript": 10,
"Both": 3,
"undefined": null
}
</code></pre>
<p>Here is is after a second POST request:</p>
<pre><code>{
"JavaScript": 0,
"TypScript": 10,
"Both": 3,
"undefined": 1
}
</code></pre>
<p>I know it might be something very simple, but I am very inexperienced so any help would be greatly appreciated!</p>
<p>I tried including some additional middleware to enable bodyParsing as I saw in other posts but that did not fix the issue.</p>
<p>I also tried</p>
<pre><code>console.logging(req.body)
</code></pre>
<p>,but that only printed "undefined".</p>
<p>EDIT:
I found the problem, I wasn't sending the information in Insomnia correctly, I need to click the form type and either format a JSON input or select the "Form URL Encoded"" Option. Otherwise it doesn't recognize the format.</p>
<p>Thank you for your help!</p>

74,324,881 | <p>I want to optionally bind a field to specific class for each profile</p>
<p>the example code is as follows ...</p>
<pre><code>spring:
config:
activate:
on-profile: test1
app:
cash:
conn:
connection-timeout: 1000
response-timeout: 2000
...
---
spring:
config:
activate:
on-profile: test2
</code></pre>
<pre class="lang-java prettyprint-override"><code>@Getter
@Validated
@ConstructorBinding
@ConfigurationProperties(value = "app.cash.conn")
@RequiredArgsConstructor
public class CashBoxConnectionProperties {
@NotNull
@Positive
private final Integer connectionTimeout;
@NotNull
@Positive
private final Integer responseTimeout;
@NotNull
@PositiveOrZero
private final Integer retryMaxAttempts;
@NotNull
@Positive
private final Integer retryMaxDelay;
}
</code></pre>
<p>When running as <code>test1</code> profile, the application runs normally because the properties value is set, but when running as <code>test2</code> profile, the error 'Binding to target...' occurs because there is no <code>app.cash.conn</code> properties.</p>
<p>The <code>CashBoxConnectionProperties</code> is not required in <code>test2</code> profile, so is there any other way than to remove <code>@NotNull</code> annotation?</p>

74,324,899 | <p>Here's the setup:</p>
<p>We have a classic <a href="https://en.wikipedia.org/wiki/Observer_pattern" rel="nofollow noreferrer">observer pattern</a>.
<code>IObserver</code> is an interface with a <code>notify</code> method. <code>RealObserver</code> implements the <code>IObserver</code> interface. <code>Subject</code> is a class with a <code>List<Observer></code>. When <code>Subject.tick()</code> is called, it loops over its list of observers and calls <code>notify</code> on each one.</p>
<p>How should this be shown in a UML sequence diagram?</p>
<p>I had something like the following:</p>
<p><a href="https://i.stack.imgur.com/FCsZQ.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FCsZQ.jpg" alt="enter image description here" /></a></p>
<p>I was told that this was incorrect because I used <code>IObserver</code> as the type (which I incorrectly labelled <code>Observer</code> -- sorry!). I was told I should never use abstract or interface types and instead use concrete classes only.</p>
<p>Is that true? If so, how should I have made this diagram? What if there were more than one implementing class of the <code>IObserver</code> interface?</p>
<p>Thanks!</p>

74,324,901 | <p>I'm trying to get back to Python but I don't get why the following code doesn't work as intended.</p>
<pre><code>class Cat:
age = 0
class Dog(Cat):
pass
Dog.age = 1
Cat.age = 2
print(Dog.age, Cat.age)
</code></pre>
<p>My output is:</p>
<pre><code>1 2
</code></pre>
<p>But why doesn't <code>Dog.age</code> equals 2?</p>
<p><code>Dog</code> is a subclass of <code>Cat</code> and modifying the class variable of the superclass <code>Cat</code> would normally affect every subclass that inherits the variable as well.</p>

74,324,924 | <p>Is there any way in Javascript to instantly access an object value with a specific depth? </p>
<p>There is an example:</p>
<pre><code>{
"level": {
"value": "one",
"level": {
"value": "two",
"level": {
"value": "three",
"level": {
"value": "four",
"level": {
"value": "five"
}
}
}
}
}
}
</code></pre>
<p>I can do that with recursion. Check the first object value <code>level</code> and if it exists then go to the next and when depth is what I need, I need to stop. And if depth is not reached and the next <code>level</code> value does not exist, then raise some error.</p>
<p>Maybe there is some other way and approach to doing that?</p>

74,324,942 | <p>I was creating a note taking program, using the user voice command. When the file already exists, I want to show an error. It runs smoothly when the file name is different though.
When the file already exists, I have coded to open in the writing mode. It would erase the earlier file, and write new instead of adding in the append mode.</p>
<pre class="lang-py prettyprint-override"><code>elif 'note' in query:
try:
speak(" Okay master. what's the file name")
b= takecommand()
f = open(f"{b}.txt","w")
speak("Okay master. tell me what to note down")
a= takecommand()
f.write(f"{a}\n")
f.close()
except Exception as e:
speak("file name already exist")
</code></pre>
<p>Can you help me with troubleshooting the script? Like how could I first make it thrown an error when the filename is same?</p>

74,324,983 | <p>I am using Azure DevOps for some application deployment. I need to have a saved variable build number that would update every time I do a build successfully and send the apk/ipa to the store.</p>
<p>Right now, from what I read in the Azure documentation and other post on StackOverflow about this, I setup my scripts this way.</p>
<p>This is my pipeline variable
<a href="https://i.stack.imgur.com/24Iic.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/24Iic.png" alt="enter image description here" /></a></p>
<p>This is my current script
<a href="https://i.stack.imgur.com/MEBhL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MEBhL.png" alt="enter image description here" /></a></p>
<p>the output is:
<a href="https://i.stack.imgur.com/dvRxe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dvRxe.png" alt="enter image description here" /></a></p>
<p>So, it seems to update my local variable but not my pipeline variable. I am unsure why since this is the example provided EVERYWHERE.</p>
<p>Sources:</p>
<ul>
<li><a href="https://learn.microsoft.com/en-us/azure/devops/pipelines/process/set-variables-scripts?view=azure-devops&tabs=bash" rel="nofollow noreferrer">https://learn.microsoft.com/en-us/azure/devops/pipelines/process/set-variables-scripts?view=azure-devops&tabs=bash</a></li>
<li><a href="https://stackoverflow.com/questions/73113958/how-to-increment-and-save-variable-in-azure-devops-pipeline">how to increment and save variable in azure devops pipeline</a></li>
</ul>
<p>Thank you for the help!</p>
<p>Edit 1: Ok, so it seems that there is a variable/function called <code>counter</code>. I haven't figured out how to use it yet, but looking into it.</p>
<p>Edit 2:
Updated my <code>azure-pipelines.yml</code></p>
<pre><code>variables:
major: 1
minor: 0
patch: 0
build: $[counter(variables['patch'], 1)]
</code></pre>
<p>On my pipeline it looks like this
<a href="https://i.stack.imgur.com/aMt1J.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aMt1J.png" alt="enter image description here" /></a></p>
<p>and my fastlane (ruby script ) lane looks like this</p>
<pre><code>lane :tf do
`echo $major`
`echo $minor`
`echo $patch`
`echo $build` # Nothing
`echo $MAJOR`
`echo $MINOR`
`echo $PATCH`
`echo $BUILD` # Nothing
`echo $(major)` # fails
end
</code></pre>
<p>those show nothing.</p>
<p>This azure DevOps is very depressing. It says here I can do a bash call to this variable.

74,324,995 | <p>I have been writing program about dragging turtles to different designated position.</p>
<p>However, <code>turtle.ondrag(turtle.goto)</code> nor <code>at[i].ondrag(at[i].goto)</code> does not work.</p>
<p>I've been amended with the solution from here <a href="https://stackoverflow.com/questions/19867476">Python turtle.ondrag not working @ Jellominer</a>, but that's seems not working for my case (with multiple turtles). The code snippet at below.</p>
<pre><code>import turtle as t
def handler(x, y, i):
global at
curTurtle = at[i]
curTurtle.ondrag(None) # disable handler inside handler
curTurtle.setheading(curTurtle.towards(x, y)) # turn toward cursor
curTurtle.goto(x, y) # move toward cursor
print(x, y, i)
curTurtle.ondrag(handler)
at = []
for i in range(3):
at.append(t.Turtle())
# Just to seperated turtles with color
at[0].color('grey')
at[0].goto(100, 100)
at[1].color('blue')
at[1].goto(0, 100)
at[2].color('green')
at[2].goto(100, 0)
for i in range(3):
at[i].ondrag(lambda x, y: handler(x, y, i))
t.listen()
t.mainloop()
</code></pre>
<p>Only the turtle with the largest index could be dragged, as seen from the <code>print(x, y, i)</code>. It's there anyways to let the drag other turtle move as well?</p>

74,325,067 | <p>I had the following pipeline:</p>
<pre><code>from typing import Sequence, List
import apache_beam as beam
def add_type(x) -> int:
return x
# no type error with Sequence, type error with List.
def print_with_type(x: Sequence[int]):
print(x)
with beam.Pipeline(argv=["--type_check_additional", "all"]) as pipeline:
lines = (
pipeline
| beam.Create([1, 2])
| beam.Map(add_type)
# removing this line should trigger type error
# | beam.combiners.ToList()
| beam.Map(print_with_type))
</code></pre>
<p>I expected a type checking error when building the pipeline, but did not get it. Only after much debugging did I realize that I should use <code>List</code> instead of <code>Sequence</code>.</p>
<p>Is this expected, as <code>Sequence</code> is one of the supported types (<a href="https://beam.apache.org/documentation/sdks/python-type-safety/#parameterized-type-hints" rel="nofollow noreferrer">doc</a>)?
Is it possible to have a warning in such cases?</p>

74,325,068 | <p>I'm trying to use <code>to_json</code> to create a json file with python. I have it working so far to produce the following sort of output:</p>
<pre><code>[
{
"Country": "A",
"Title": "B",
"Category": "C"
},
{
"Country": "D",
"Title": "E",
"Category": "F"
}
]
</code></pre>
<p>But I need it to create a json file that looks like this. Quite simply, to add the "data" name. Any tips on how to do so?</p>
<pre><code>{
"data": [
{
"Country": "A",
"Title": "B",
"Category": "C"
},
{
"Country": "D",
"Title": "E",
"Category": "F"
}
]
}

74,325,069 | <p>One requirement of mine is - Using windows, not use any tools not already available as part of aws cli or windows
For example, I have this json file test.json with below content:</p>
<p><code>"My number is $myvar"</code></p>
<p>I read this into a powershell variable like so:</p>
<pre><code>$myobj=(get-content .\test.json | convertfrom-json)
$myvar=1
</code></pre>
<p>From here, I would like to do something with this <code>$myobj</code> which will enable me to get this output:</p>
<pre><code>$myobj | tee json_with_values_from_environment.json
My number is 1
</code></pre>
<p>I got some limited success with iex, but not sure if it can be made to work for this example</p>

74,325,166 | <p>I am using <strong>Google Photos</strong> to host photos for a website I am managing, and accessing them via <strong>GraphQL</strong> and <strong>Gastby</strong> (gatsby-image-plugin)</p>
<p>The images are shown in a gallery, but open up in a light-box gallery slider - I'm using FancyApps/ui (v4.x). Anyway the maximum size of the images are the maximum size of the source set (i.e. 512px). This means on a big screen the full screen image looks small (only 512px wide). You can see these values on the screen-grab below:</p>
<pre><code>"original": {
"width": 512,
"height": 341
}
</code></pre>
<p>The original image is 1200px width, which is confirmed by the media metadata:</p>
<pre><code>"mediaMetadata": {
"height": "800",
"width": "1200"
}"
</code></pre>
<p>Which is the same as images > sources > sizes:
<code>"sizes": "(min-width: 512px) 512px, 100vw"</code></p>
<p>I realise I can force the value by specifying gatsbyImageSharp to have a width of 1200.</p>
<pre><code>{
allGooglePhotosAlbum(filter: {title: {eq: "assorted"}}) {
nodes {
title
photos {
file {
childImageSharp {
id
gatsbyImageData(placeholder: BLURRED, width: 1200)
original {
width
height
}
}
}
mediaMetadata {
height
width
}
}
}
}
}
</code></pre>
<p>However some of the images are not 1200px wide (i.e. the portrait images), I get the following warning:</p>
<pre><code>The requested width "1200px" for a resolutions field for the file URL_HERE was larger than the actual image width of 512px! If possible, replace the current image with a larger one.
</code></pre>
<p>I don't like the warning, but more importantly I think this might make the height of the image too large to be displayed properly (i.e. either would be cropped or larger than the screen height - 100vh).</p>
<p>Surely there, should be a way to set the largest image width/height to the heights provided by the media metadata (i.e. the full un-adulterated image).</p>

74,325,280 | <p>so I take a user input in a loop seen below</p>
<pre><code>mail_list = []
x = 0
while x >= 0:
user_input = input('enter first name, last name, ID, and email domain: ')
mail_list.append(user_input)
if user_input == 'done':
break
</code></pre>
<p>so it is supposed to add the first name, last name, and email domain together to make a full email address. not sure if lists are the best path to go or splicing the spring. The problem I ran into when trying to just splice it would only use 'done' as the last input so I assumed adding it to a list would be the best path. just lost</p>

74,325,310 | <p>I am new to postgresql and am trying to update a table based on conditions using PostgreSQL stored procedure.
The table 'pref2' looks like this:</p>
<pre><code>geneid pred_perf_r2 pred_perf_pval vers
ENSG00000107959 0.03 0.02 1.0
ENSG00000106321 0.05 0.01 1.0
ENSG00000102222 0.22 0.05 1.0
ENSG00000101111 0.11 0.03 1.0
ENSG00000102355 0.33 0.01 1.0
</code></pre>
<p>I want to create a stored procedure for updating this table for pred_perf_r2 and pred_perf_pval if the new scores are better (bigger R2 and smaller pval). My attempt:</p>
<pre><code>create or replace procedure new_version(
gene varchar(50),
new_r2 numeric,
new_p numeric,
new_v numeric
)
language plpgsql
as $$
begin
if (new_r2 > perf2.pred_perf_r2)
and (new_p < perf2.pred_perf_pval) then
update perf2 set
perf2.pred_perf_r2 = new_r2,
perf2.pred_perf_pval = new_p ,
perf2.vers = new_v
where perf2.geneid = gene;
end if;
commit;
END;$$
call new_version('ENSG00000107959',0.55,0.01,2.0);
select * from perf2;
</code></pre>
<p>It gives me this error:</p>
<pre><code>ERROR: missing FROM-clause entry for table "perf2"
LINE 1: (new_r2 > perf2.pred_perf_r2)
^
QUERY: (new_r2 > perf2.pred_perf_r2)
and (new_p < perf2.pred_perf_pval)
CONTEXT: PL/pgSQL function new_version(character varying,numeric,numeric,numeric) line 3 at IF
SQL state: 42P01
</code></pre>
<p>My desired result will look like this when calling the stored procedure:</p>
<pre><code>geneid pred_perf_r2 pred_perf_pval vers
ENSG00000107959 0.55 0.01 2.0
ENSG00000106321 0.05 0.01 1.0
ENSG00000102222 0.22 0.05 1.0
ENSG00000101111 0.11 0.03 1.0
ENSG00000102355 0.33 0.01 1.0
</code></pre>
<p>if</p>
<pre><code>call new_version('ENSG00000107959',0.02,0.05,2.0);
</code></pre>
<p>The original table should not change since R square is worse (0.02 < 0.03) and pval is larger (0.05>0.02)
It keeps giving me errors. Any ideas on how I can fix this?</p>

<p>I have a dataset like the above. Basically it's like a website session which I have a start + end activity, and in between there could be other unrelated records.</p>
<p>I need to pull the records based on:</p>
<ul>
<li>I need to report all the "end" activity from the table</li>
<li>In each "end" record, I need to find its nearest previous "start" row's "Content_ID" value. The record must also match the "Profile_ID" as well</li>
<li>The result I expected is as follows:</li>
</ul>
<p><a href="https://i.stack.imgur.com/BT9iQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BT9iQ.png" alt="enter image description here" /></a></p>
<p>May I ask how could I construct the SQL to do this?</p>
<p>Thanks so much!</p>

of keeping the pointer to the array, it keeps a copy of the word inside the queue.</p>

<pre><code>void delete(Queue *q)

74,325,368 | <p>I have a Kafka application which suffers from intermittent deserialisation errors (due to connectivity problems to the host which provides Avro schemas)</p>
<p>I would like to back off and retry serialisation exceptions, but I have not been able to figure out how to set that up.</p>
<p>Here's my test configuration:</p>
<pre class="lang-java prettyprint-override"><code>@org.springframework.context.annotation.Configuration
@EnableKafka
public class Configuration {
@Bean("myContainerFactory")
public ConcurrentKafkaListenerContainerFactory<String, String> createFactory(
KafkaProperties properties
) {
var factory = new ConcurrentKafkaListenerContainerFactory<String, String>();
factory.setConsumerFactory(
new DefaultKafkaConsumerFactory(
properties.buildConsumerProperties(),
new StringDeserializer(),
new ErrorHandlingDeserializer(new MyDeserializer())
)
);
factory.getContainerProperties().setAckMode(
ContainerProperties.AckMode.MANUAL_IMMEDIATE
);
factory.setCommonErrorHandler(new DefaultErrorHandler());
return factory;
}
// this fakes occasional errors which succeed after a retry
static class MyDeserializer implements Deserializer<String> {
int retries = 0;
@Override
public String deserialize(String topic, byte[] bytes) {
String s = new String(bytes);
if (s.contains("7") && retries == 0) {
retries = 1;
throw new RuntimeException();
}
retries = 0;
return s;
}
}
}
</code></pre>
<p>and my consumer:</p>
<pre class="lang-java prettyprint-override"><code>@Component
public class StringListener {
@KafkaListener(
topics = {"string-test"},
groupId = "test",
batch = "true",
containerFactory = "myContainerFactory"
)
public void listen(List<String> messages, Acknowledgment acknowledgment) {
for (String s: messages) {
System.out.println(s);
}
acknowledgment.acknowledge();
}
}
</code></pre>
<p>At present the <code>ErrorHandlingDeserializer</code> just returns <code>null</code>.</p>
<p>Do I need to implement a <code>failedDeserializationFunction</code>, or is there a there a simple way to configure the factory so that my deserialiser is called again, after a configurable wait, for some configurable number of times?</p>

74,325,370 | <p>I have a table "store" and a table "product". Each store has multiple products but a product only has one store ( one to many relationship ). The tables might look something like:</p>
<p>store: id, name<br />
product: id, name, store_id</p>
<p>when querying the store and its products using supabase I simply do:</p>
<pre><code> .from("store")
.select(
id
name,
product(name)
)
</code></pre>
<p>which would return</p>
<pre><code> id: "some_id",
name: "some_name",
products: [
{...},
{...}
]
}
</code></pre>
<p>or something along those lines depending on what data I want. However, I need to run this query in pure SQL and I can't seem to figure it out.</p>
<p>I tried to JOIN the tables together but it leads to a lot of duplicated data since the store's data is in all the rows</p>

74,325,399 | <p>Currently I have 2 array lists showing words and their frequency. So "the" has a frequency of 1, "I" has a frequency of 10 and so on.</p>
<pre><code> ArrayList<String> words = new ArrayList<>(Arrays.asList("the", "I", "false","too"));
ArrayList<Integer> frequency = new ArrayList<>(Arrays.asList(1, 10, 5, 7));
Collections.sort(frequency, Collections.reverseOrder());
</code></pre>
<p>What I want to do is sort them from highest word frequency to lowest, so I used Collections.sort to sort frequency from highest values to lowest. This gives me the expected result of</p>
<p>[10, 7, 5, 1]</p>
<p>But now I'm at a complete standstill has to how to sort the words ArrayList so that the indexes of each list still correspond to each other.</p>
<p>My desired output would be for the words arraylist would be.</p>
<p>["I", "too", "false", "the"]</p>
<p>Is there some kind of method within Collections that can accomplish this?</p>

74,325,524 | <p>I am trying to solve this problem on HackerRank and I am having a issue with my logic. I am confused and not able to think what I'm doing wrong, feels like I'm stuck in logic.</p>
<p>Question link: <a href="https://www.hackerrank.com/challenges/game-of-thrones/" rel="nofollow noreferrer">https://www.hackerrank.com/challenges/game-of-thrones/</a></p>
<p>I created a dictionary of alphabets with value 0. And then counting number of times the alphabet appears in the string. If there are more than 1 alphabet characters occurring 1 times in string, then obviously that string cannot become a palindrome. That's my logic, however it only pass 10/21 test cases.</p>
<p>Here's my code:</p>
<pre><code>def gameOfThrones(s):
alpha_dict = {chr(x): 0 for x in range(97,123)}
counter = 0
for i in s:
if i in alpha_dict:
alpha_dict[i] += 1
for key in alpha_dict.values():
if key == 1:
counter += 1
if counter <= 1:
return 'YES'
else:
return 'NO'
</code></pre>
<p>Any idea where I'm going wrong?</p>

74,325,565 | <p>This maybe a simple question but I couldn't figure it out myself nor could I find an online resource for it.</p>
<p>I have to develop a REST API using spring boot. I see two options to accept the json payload (max payload size 3 MB in some cases)</p>
<p><strong>Option 1: Ask clients to send json in request body. Let Jackson convert it to Java object</strong></p>
<pre><code>@RestController
public class EmployeeController {
@PostMapping
public void createEmployees(@RequestBody List<Employee> employees) {
// do something with employees
}
}
</code></pre>
<p><strong>Option 2: Ask clients to upload a json file and let the controller accept Multipart payload</strong></p>
<pre><code>@RestController
public class EmployeeController {
@PostMapping(consumes = { MediaType.MULTIPART_FORM_DATA_VALUE })
public void createEmployees(@RequestParam(name = "file") MultipartFile file) {
// convert multipart file data to List of Employee objects
//do something with employees
}
}
</code></pre>
<p>Which option is better and why?</p>

74,325,613 | <p>What would be considered best practice for implementing a persistent shopping cart in an ASP.net Web Forms(*) based application? The only built-in way seems to be involving the Session state, which is not ideal because once you close the browser... it's gone. One way seems to be involving the localStorage via Javascript, but that creates awkward client/server mixups, as the data processing is meant to be done server side.</p>
<p>(* please pay attention to that part - MVC or Blazor based solutions will not work for this particular case)</p>

74,325,669 | <p>I'm trying to create a POST call using HttpClient that I have fully working in Postman. Here is the body I'm sending in Postman:</p>
<pre><code>{
"searchType": "games",
"searchTerms": [
"mario"
],
"searchPage": 1,
"size": 20,
"searchOptions": {
"games": {
"userId": 0,
"platform": "",
"sortCategory": "popular",
"rangeCategory": "main",
"rangeTime": {
"min": 0,
"max": 0
},
"gameplay": {
"perspective": "",

"genre": ""
},
"modifier": ""
},
"users": {
"sortCategory": "postcount"
},
"filter": "",
"sort": 0,
"randomizer": 0
}
}
</code></pre>
<p>I have this written as the following in C#:</p>
<pre><code>var client = _httpClientFactory.CreateClient(HttpClients.HowLongToBeat.ToString());
var request = new HowLongToBeatRequest
{
SearchType = "games",
SearchTerms = searchTerm.Trim().Split(" "),
SearchPage = 1,
Size = 20,
SearchOptions = new SearchOptions
{
Games = new SearchOptionsGames
{
UserId = 0,
Platform = "",
SortCategory = "popular",
RangeCategory = "main",
RangeTime = new SearchOptionsGamesRangeTime
{
Min = 0,
Max = 0
},
Gameplay = new SearchOptionsGamesGameplay
{
Perspective = "",
Flow = "",
Genre = ""
},
Modifier = ""
},
Users = new SearchOptionsUsers
{
SortCategory = "postcount"
},
Filter = "",
Sort = 0,
Randomizer = 0
}
};
//var json = JsonSerializer.Serialize(request);
//var content = new StringContent(json, Encoding.UTF8, "application/json");
//var response = await client.PostAsync("api/search", content);
var response = await client.PostAsJsonAsync("api/search", request, new JsonSerializerOptions
{
PropertyNamingPolicy = JsonNamingPolicy.CamelCase
});
return new HowLongToBeatResponse();
</code></pre>
<p>I have this set up as</p>
<p>The url I'm hitting is: <code>https://www.howlongtobeat.com/api/search</code> and I'm setting it up like so in my Startup.cs</p>
<pre><code>services.AddHttpClient(HttpClients.HowLongToBeat.ToString(), config =>
{
config.BaseAddress = new Uri("https://www.howlongtobeat.com/");
config.DefaultRequestHeaders.Add("Referer", "https://www.howlongtobeat.com/");
});
</code></pre>
<p>I am passing this Referer header in my Postman collection as well.</p>
<p>Basically, I can't figure out why this code gets a 403 in C# but the Postman that I think is exactly the same is getting a successful response. Am I missing something?</p>
<p>Let me know if there's any missing info I can provide.</p>

74,325,685 | <p>It will take two keys as input key1 and key2 and finds the node with key1, then changes it
to key2. This may disturb the BST property (of having smaller things to the left and bigger
to the right); this function should make appropriate changes in tree so that it becomes BST
again.</p>
<p>I tried making links of the new data with links of the older node to be replaced with ,but I can organize my tree precisely.</p>

74,325,702 | <p>Let's say I have a a <code>vector<vector<int>></code>. I want to use <code>ranges::transform</code> in such a way that I get</p>
<pre class="lang-cpp prettyprint-override"><code>vector<vector<int>> original_vectors;
using T = decltype(ranges::views::transform(original_vectors[0], [&](int x){
return x;
}));
vector<int> transformation_coeff;
vector<T> transformed_vectors;
for(int i=0;i<n;i++){
transformed_vectors.push_back(ranges::views::transform(original_vectors[i], [&](int x){
return x * transformation_coeff[i];
}));
}
</code></pre>
<p>Is such a transformation, or something similar, currently possible in C++?</p>
<p>I know its possible to simply store the <code>transformation_coeff</code>, but it's inconvenient to apply it at every step. (This will be repeated multiple times so it needs to be done in <code>O(log n)</code>, therefore I can't explicitly apply the transformation).</p>

74,325,767 | <p>I am trying to build an ASP.NET Core hosted Blazor web app. I have two entities with a one-to-many relationship.</p>
<p>There is one portfolio that has many securities.</p>
<p>Portfolio entity</p>
<pre><code>public class Portfolio
{
[Key]
public int PortfolioId { get; set; }
[Required]
public string NameOfPortfolio { get; set; }
public string Description { get; set; } = string.Empty;
public DateTime DateTimeCreated { get; set; } = DateTime.UtcNow;
public virtual ICollection<Security>? Securities { get; set; }
}
</code></pre>
<p>Security entity</p>
<pre><code>public class Security
{
[Key]
public int Id { get; set; }
[Required]
public string SecurityName { get; set; } = string.Empty;
[Required]
public float Price { get; set; }
[Required]
public int StockesOwned { get; set; } = 0;
[Required]
public float StocksValue { get; set; }
public DateTime DateTimeObtained { get; set; } = DateTime.UtcNow;
public string? Description { get; set; } = string.Empty;
public Portfolio Portfolio { get; set; }
}
</code></pre>
<p>The <code>Security</code> must have a <code>Portfolio</code>, but a portfolio may not have a security.</p>
<p>I am trying whenever I want to add a security I must specify the portfolio that contains that security. I am trying to bind the <code>security.Portfolio</code> to a <code>Portfolio</code> and I can not implement it correctly.</p>
<p>Whenever I try to bind it that way</p>
<pre><code><div class="row w-100">
<div class="col-6">
Portfolio
</div>
<div class="col-md-4">
<select class="form-control" >
<option value="" bind=@Security.Portfolio>Select Portfolio</option>
@foreach (var portfolio in Portfolios)
{
<option value="@portfolio.PortfolioId">@portfolio.NameOfPortfolio</option>
}
</select>
</div>
</div>
</code></pre>
<p>It returns an error 400 and it mentions that the portfolio is required</p>
<p>Also here is the service in the client</p>
<pre><code>public async Task CreateSecurity(Security security)
{
var response = await _http.PostAsJsonAsync("api/security", security);
if (response.IsSuccessStatusCode)
{
var result = await response.Content.ReadFromJsonAsync<ServiceResponse<int>>();
if (!(result?.Success ?? false))
{
}
}
}
</code></pre>
<p>The controller</p>
<pre><code>[HttpPost]
public async Task<ActionResult<ServiceResponse<int>>> CreateSecurity(Security security)
{
var result = await _securityService.CreateSecurityAsync(security);
return Ok(result);
}
</code></pre>
<p>The service in the server</p>
<pre><code>public async Task<ServiceResponse<int>> CreateSecurityAsync(Security security)
{
_context.Securities.Add(security);
int result = await _context.SaveChangesAsync();
return new ServiceResponse<int>
{
Data = result,
Success = result > 0,
Message = "The" + security.SecurityName + "has been saved!"
};
}
</code></pre>
<p>Sorry if I misspelled something or did something wrong. I am new to this. Thanks in advance.</p>

<pre><code>itemPrices: [{regionId: "A", price: "200"},{regionId: "B", price: "100"}]
</code></pre>
<p>As the user presses add button new input fields get added. <br>
For this I have taken an empty array=> <code>itemPrices: [],</code> inside vue app data.
<br>Now Inside table element I have this code:<br></p>
<pre><code><vs-tr v-for="n in num" v-bind:key="n">
<vs-td
><vs-input
v-model="itemPrices[n].regionId"
placeholder="Region Name"
/></vs-td>
<vs-td>
<vs-input
placeholder="price"
v-model="itemPrices[n].price"
/>
</vs-td>
</vs-tr>
</code></pre>
<p>Here 'num' is just an integer which decides how many rows should be there. But this is not working... What is a possible solution for this task?</p>

74,325,916 | <p>I do get a warning whenever I throw an exception in my code without explicitly stating it in the docblocs:
<a href="https://i.stack.imgur.com/I4Kse.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/I4Kse.png" alt="enter image description here" /></a></p>
<p>I know this can be fixed by adding <code>@throw</code> tags, but the warning is actually not 100% true, as I do handle the exception in <code>/app/Exceptions/Handler.php</code>. I would like to disable the warning for this single exception. Is this possible in PHPStan? I have not found anything in the docs, but in this blog post <a href="https://phpstan.org/blog/bring-your-exceptions-under-control" rel="nofollow noreferrer">https://phpstan.org/blog/bring-your-exceptions-under-control</a> it seems that one can have unchecked & checked exceptions, and I believe unchecked exceptions do not need to be declared. However, marking my exception unchecked in <code>phpstan.neon</code> does not get rid of the error:</p>
<pre><code> exceptions:
uncheckedExceptionClasses:
- 'app\Exceptions\AuthenticationException'
</code></pre>
<p>I also noticed that the <code>Symfony\Component\HttpKernel\Exception\NotFoundHttpException</code> exception does not trigger the warning. I am not sure why, but it seems there is already a set of exceptions where no <code>@throw</code> is needed.</p>
<p><a href="https://i.stack.imgur.com/xDJI5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xDJI5.png" alt="enter image description here" /></a></p>

74,325,929 | <p>When I try to specify the parameter names when calling a function from inside a JavaScript class constructor, I get a <code>ReferenceError</code>.</p>
<p>I will show the problem based on a simplified example:</p>
<p>Suppose I have an object and methods like so:</p>
<pre><code>class Person {
constructor(name, age) {
this.name = name,
this.age = age
}
addYear() {
this.age++;
}
changeName(newName) {
this.name = newName;
}
changeAge(newAge) {
this.age = newAge;
}
changeAgeAndName(newName, newAge) {
this.changeName(newName=newName);
this.changeAge(newAge=newAge);
}
}
</code></pre>
<p>All works fine if I instanciate it, and if mingle with it a bit this is the code and output:</p>
<pre><code>let p1 = new Person('George', 20);
console.log(p1);
p1.changeName(newName='Robert');
console.log(p1);
p1.changeAgeAndName(newName='Joe', newAge=23);
console.log(p1);
</code></pre>
<pre><code>Person { name: 'George', age: 20 }
Person { name: 'Robert', age: 20 }
Person { name: 'Joe', age: 23 }
</code></pre>
<p>Now, let's say I want to use changeAgeAndName inside the constructor like so (specifying the parameter names for the variables):</p>
<pre><code> constructor(name, age) {
this.changeAgeAndName(newName=name, newAge=age);
}
</code></pre>
<p>I get an error:</p>
<pre><code>this.changeAgeAndName(newName=name, newAge=age);
</code></pre>
<pre><code>ReferenceError: newName is not defined
</code></pre>
<p>But if I don't specify the parameter names, all is fine:</p>
<pre><code> constructor(name, age) {
this.changeAgeAndName(name, age);
}
</code></pre>
<p>Eventual Output:</p>
<pre><code>Person2 { name: 'Mike', age: 40 }
</code></pre>
<p>If I specify the parameter names outside the constructor, all is fine as well.
I like to be as explicit as possible when coding, so I was wondering what I may be doing wrong. Also, I was curious about perhaps yet another example of peculiar JS behavior. Thank you!</p>

74,325,947 | <p>Hi StackOverFlow community,
that's my first question here and I'm glad to be part of this community as it already helped me in plenty of things. I looked on this topic and didn't manage to find anything.
I would like to redirect the DefaultTabController to the new tab created after waiting that it's loaded and built.
I managed to find a workaround with the awaiting a Future.delayed wrapping setState but I don't think it's the best solution out there.
When not using this FutureDelayed I get an error due to the fact that the button function is trying to redirect to a tab not yet crated as the DefaultTabController has not been yet rebuilt.</p>
<p>Function for adding a new tab inside a bottomSheet</p>
<pre><code>Future<int> _addNewTab() async {
await showModalBottomSheet(
...
...
IconButton(
onPressed: () {
final isValid =
_formKey.currentState!.validate();
if (!isValid) {
return;
}
Navigator.pop(context);
setState(() {
_tabs
.add(_newTab.text);
});
}
return _tabs.lenght-1;
</code></pre>
<p>Widget inside which I call the function</p>
<pre><code>return DefaultTabController(
...
...
floatingActionButton: Padding(
//button to add a new tab
padding: const EdgeInsets.only(bottom: 25.0),
child: IconButton(
icon: Icon(
Icons.add_circle,
size: 55,
),
onPressed: () async {
var page = await _addNewTab();
//awaiting this future delayed because we can't show a page which is not built yet
await Future.delayed(const Duration(milliseconds: 10),
() {
setState(() {});
});
//moving to the new tab built after awaiting it
if (mounted) { //checking that context is still alive and usable
DefaultTabController.of(context)!.animateTo(page);
}
},
</code></pre>
<p>Thanks a lot for your help in advance :)</p>

74,325,983 | <p>I am trying to understand how first class functions work in R. I had understood that functions were first class in R, but was sorely disappointed when applying that understanding. When a function is saved to a list, whether that be as an ordinary list, a vector or a dictionary style list or vector, it is no longer callable, leading to the following error:</p>
<pre><code>Error: attempt to apply non-function
</code></pre>
<p>e.g.</p>
<pre><code>print_func <- function() {
print('hi')
}
print_func()
[1] "hi"
my_list = list(print_func)
my_list[0]()
Error: attempt to apply non-function
my_vector = c(print_func)
my_vector[0]()
Error: attempt to apply non-function
my_map <- c("a" = print_func)
my_map["a"]()
Error: attempt to apply non-function
</code></pre>
<p>So why is this? Does R not actually treat functions as first class members in all cases, or is there another reason why this occurs?</p>
<p>I see that R vectors also do unexpected things (for me - perhaps not for experienced R users) to nested arrays:</p>
<pre><code>nested_vector <- c("a" = c("b" = 1))
nested_vector["a"]
<NA>
NA
nested_vector["a.b"]
a.b
1
</code></pre>
<p>Here it makes sense to me that "a.b" might reference the sub-member of the key "b" under the key "a". But apparently that logic goes out the window when trying to call the upper level key "a".</p>

74,326,008 | <p>i try to create linear function in an interval and the other interval is 0. and add it to an array</p>
<p>so i tried this code</p>
<pre><code>import numpy as np
import sympy as sp
import matplotlib as plt # This is all the library's i need
import mpmath
x = sp.symbols('x')
n = 10
xx = (np.array([np.linspace(0, 1, n+1)]))
i = 0
N = []
N[0] = sp.Piecewise( ((xx[0, i + 1] - x) / (xx[0, i + 1] - xx[0, i]), xx[0, i] <= x),
((xx[0, i + 1] - x) / (xx[0, i + 1] - xx[0, i]), x <= xx[0, i + 1]),
(0, True)
)
</code></pre>
<p>and it always returns</p>
<pre><code> line 511, in __bool__
raise TypeError("cannot determine truth value of Relational")
TypeError: cannot determine truth value of Relational
</code></pre>
<p>EDIT: after i add x is positive to symbol
i try to make a vector of linear function in the intervals in a loop and i don't know why it refuses to determine the the truth value even tough in the line above it succeed:</p>
<pre><code>import sympy as sp
import matplotlib as plt # This is all the library's i need
import mpmath
x = sp.symbols('x', positive=True)
n = 10
xx = (np.array([np.linspace(0, 1, n+1)]))
i = 0
N = []
a = sp.Piecewise(
((xx[0, i + 1] - x) / (xx[0, i + 1] - xx[0, i]), (xx[0, i]) <= x),
((xx[0, i + 1] - x) / (xx[0, i + 1] - xx[0, i]), (x <= (xx[0, i + 1]))),

<p>Here is the php</p>

<p>Yes it is just this 1 line of code.</p>
<p>for some reason the output would be "else" instead of my expected "if"</p>

<p>I tried putting other words instead of success but it resulted in the same problem. Which is it goes to the else statement.</p>
<p><strong>I found the answer</strong></p>
<p>data is literally equals to "success" with double quotation on them.
To fix it I had to do this.</p>
<pre><code>String success = "\"success\"";

74,326,251 | <p>Please excuse how utterly "noobish" I am, I'm trying to learn as I go along but I'm <em>very</em> new.</p>
<p>I have the below code which I'm trying to use for a Discord bot. For the most part it works, however the @ "ping" simply returns "@undefined" as opposed to the values I've set in the consts.</p>
<p>Would anyone be so kind as to point me in the right direction on this?</p>
<pre><code> const ping = {
roleID: function() {
return this.role;
}
}
const John = {
role:"abc"
}
const Mary = {
role:"123"
}
function pingSubbed() {
let pingID = message.author.username;
if (pingID == "John") {
ping.roleID.call(John);
}
if (pingID == "Mary") {
ping.roleID.call(Mary);
}
}
yield hook.send(`**${message.author.username}**\n` + " " + messageContents + " " + "@"+pingSubbed());
</code></pre>
<p>I'm expecting the function pingSubbed() to determine the username of the person who posts in Discord, for example John, reference the above ping.roleID.call(John) and then take the appropriate role (in this case John = abc) and sending this information as a message itself - @123 - as in the last line "@"+pingSubbed()</p>

<p>Basically, the code above will adjust the "printarea" if it has crossed the limit I have set, but I want to add an "Exit for" command to stop the loop after the "If-then" criteria is met.`</p>
<p>I already tried to make</p>
<pre><code>If po.Range("M4") + 2 > po.Range("O6") Then
po.PageSetup.PrintArea = "$B$1:$L$43
Exit for

<p>but the "Exit for" code will run along with the printarea change, so my last page has not been printed yet. What I want is for the loop to stop after my last page is printed (where my last page will always be related to the "if then" above).</p>

<p>My program is very simple : a process is forked; the child process reads 4 characters from <em>stdin</em> and when it finishes, the parent process reads 4 characters from <em>stdin</em>.</p>
<p>Normally, if I write characters in <em>stdin</em> (before the fork) the child process should read the first 4 characters and then the parent process should read the next 4 characters. It seems quit logical as <em>fork()</em> duplicates the parent process, including the file descriptors and opened files.</p>
<p>But, when I execute
<code>echo 'aaaaaaaaa' | ./my_program</code>
I get
<code>Child : aaaa Parent : eof = 1</code></p>
<p>It seems that <em>stdin</em> has been emptied by the child process when it finished.
I having hard time explaining this behavior.</p>
<p>Can you help me ? :)</p>
