<p>I need to do number of inputs that it dynamic's number , and for every input other name because I want to use in these inputs.</p>
<p>I call to the function in jsx with that</p>
<pre><code>Array.apply(null, { length: numberInputs}).map((e, i) => (
<InputsNumber key={i} />
))
</code></pre>
<p>and I tried do for loop but because the function InputsNumber return tags of html it doesn't work well and the number is dynamic but all the number there same as my dynamic's number inputs</p>

<p>I have a function that contains a data.table with specific values:</p>
<pre><code> add_q <- function () {
DT = data.table (X = c("A", "A1", "B", "B1"), Y = c("C", "C1", "D", "D1"))}
</code></pre>
<p>This will give my two columns X and Y with the values. I want to make a 3rd column that would have the values YES for values that have A, C, A1, C1 and the value NO for the rest.</p>
<p>How to do that?</p>

<p>I am connecting to an api and returning some data on screen using the below:</p>
<pre><code>return (
<>
{Object.values(items).map((item, index) => {
return <pre>{JSON.stringify(item, null, 2)}</pre>
</>
})}
</code></pre>
<p>This returns an object to the front end that looks like this.</p>
<pre><code>[
{
"type": "player",
"id": "account.ac12c743e8044d42a6eafeffa2c3a8cf",
"attributes": {
"name": "JohnnyUtah",
"stats": null,
"titleId": "pubg",
"shardId": "stadia",
"patchVersion": ""
},
"relationships": {
"assets": {
"data": []
},
"matches": {
"data": [
{
"type": "match",
"id": "473019a4-fe3b-420a-b00e-b99ff2cd8c73"
</code></pre>
<p>I would like to as an example get just the id as shown below:</p>
<pre><code>"id": "account.ac12c743e8044d42a6eafeffa2c3a8cf"
</code></pre>
<p>However I have an object with an array of objects inside of it and I don't know how to access this.</p>
<p>I am familiar with the array map function which I believe I need to use, but I don't know how to get inside that array in the object being returned.</p>
<p>I'm therefore struggling to see how I get at this value.</p>
<hr />
<p>Adding full code as this may help clarify things:</p>
<pre><code>import React, { useEffect, useState } from 'react'
function Player() {
const [player,setPlayer] = useState('JohnnyUtah')
const [items,setItems] = useState([])

const apiKey = "key";

<p>Giving this dictionary:</p>
<pre class="lang-py prettyprint-override"><code> d = {'x': '999999999',

</code></pre>
<p>is it possible to make a <code>set</code> of <code>tuples</code> ?</p>
<p>The output should be <code>{( x, 999999999),(y,888888888, 333333333),...}</code></p>
<p>I tried this : <code>x_set = {(k, v) for k, values in d.items() for v in values} </code></p>

<p>I made a simple text with a transition, appearing from left to right when I hover it in CSS.</p>
<p>My code is very simple, as seen in the snippet.</p>
<p>So of course, when I remove my mouse cursor, it is animated in the other direction and the text disappears from right to left.
BUT
I'd like it to disappear from left to right and then reset so it can appear again from left to right, and that's where I'm stuck.</p>
<p>What would be your approach to get such an effect?</p>
<p>Thanks!</p>

<p>I'm trying to code a countdown timer to Christmas day. Below is what I have. However, <code>days</code> is coming out as <code>3</code> for some reason. If I set the <code>then</code> date up <code>22nd December</code> - it will calculate it right but any dates after that it seems to start from <code>1</code> - meaning if I set it to <code>2022-12-23 00:00:00</code>, days is outputting <code>1</code>, <code>2022-12-24 00:00:00</code> will give me <code>2</code> days to the countdown. I'm a bit confused what is happening here...</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">

<p>I want to create a custom ListView that wrap the children with something common (and a few logic to disable them). However the children contents are <strong>unknown and different for each child</strong> and is managed by the parent.</p>
<p>Input (from, say, <code>Index.razor</code> and the component is <code>MyList.razor</code>):</p>
<pre class="lang-html prettyprint-override"><code><!-- Other code -->
<MyList>
<Child Title="Paragraph">
<p>May have any HTML content</p>
</Child>
<Child Title="Link">
<a href="://example.com">Example Link</a>
</Child>
<Child Title="Custom HTML">
<div>Could be anything in here</div>
<button onclick="this.OnButtonClicked">Click Me</button>
</Child>
</MyList>
</code></pre>
<p>The result:</p>
<pre class="lang-html prettyprint-override"><code><div class="list">
<div class="child">
<p>Row 1: Paragraph @*Title here*@</p>
<div class="row-content"> @*HTML content here*@
<p>May have any HTML content</p>
</div>
</div>
<div class="child">
<p>Row 2: Link @*Title here*@</p>
<div class="row-content"> @*HTML content here*@
<a href="://example.com">Example Link</a>
</div>
</div>
<!-- More -->
</div>
</code></pre>
<p>I have tried <a href="https://learn.microsoft.com/en-us/aspnet/core/blazor/components/templated-components" rel="nofollow noreferrer">templated components</a> but the template is fixed for all chidden. <a href="https://learn.microsoft.com/en-us/aspnet/core/blazor/components/dynamiccomponent" rel="nofollow noreferrer">Dynamically-rendered ASP.NET Core Razor components</a> would require me to make a component class for each child which is not very desirable. Is there any solution to my question?</p>
<hr />
<p>This is my best attempt so far but I do not know how to pass the <code>RenderFragment</code>s to the children:</p>
<pre class="lang-html prettyprint-override"><code><app-board>
@{
var i = 0;
}
@foreach (var row in this.Rows)
{
var z = i;
<fieldset class="board-row" disabled="@(this.CurrentStep < z)">
<board-col>
<span class="step-num">@(z)</span>
<span class="step-title">@(row.Title)</span>
</board-col>
<board-col>
@(row.Html)
</board-col>
</fieldset>
}
</app-board>
</code></pre>
<pre class="lang-cs prettyprint-override"><code>public partial class AppBoard
{
[Parameter, AllowNull]
public IReadOnlyList<AppBoardRow> Rows { get; set; }
[Parameter]
public int CurrentStep { get; set; } = -1;
public record AppBoardRow(string Title, RenderFragment Html);
}
</code></pre>
<p>I don't know how I can use it in <code>Index.razor</code>:</p>
<pre class="lang-html prettyprint-override"><code><AppBoard>
<!-- What's here? -->
</AppBoard>
</code></pre>

<p>I am a beginner. I have this problem I am not sure if I will be able to explain it adequately but let's see:</p>
<p>I have an array called userid and another array called username. I want the user to give me his/her id after that I wish that the name user will type has to be the same array number from the username array
for example if the user types 5 then his/her name must be "f" otherwise user can't go any further.</p>
<p>I don't know what to type in if statement?</p>
<pre><code>class Program
{
static void Main(string[] args)
{
string[] userid = {"0" , "1" , "2" , "3" , "4" , "5"};
string[] username = { "a" , "b" , "c" , "d" , "e" , "f"};
Console.Write("please type user id: \t");
string useridreply= Console.ReadLine();
Console.Write("please type user name: \t");
string usernamereply = Console.ReadLine();
if (usernamereply == username[useridreply])
{
}
}
}
</code></pre>

<p>I have a specific question relating a foreach loop in C# and Blazor Web Assembly.</p>
<p>This is my foreach loop containing a keyvaluepair:
`</p>
<pre><code>@foreach (KeyValuePair<int, string> pair in detail.Years2Value.OrderBy(x => x.Key))
{
<td colspan="1"><input type="text" class="radius form-control" style="background-color:transparent; border:0.1px" readonly="readonly" value=@pair.Value></td>
}
<td colspan="1" class="border-left border-right"></td>
</code></pre>
<p>`
I want to display all values in a range and in a Region. After each region it should create an empty row to make it look better and more organized. Thats why I am adding a td after the foreach.
This creates following problem: --> See Picture below!
after the last foreach in my last Region is done, I don't want to create a new td but I don´t know how to achieve this.</p>
<p><img src="https://i.stack.imgur.com/jFZNz.png" alt="Picture showing the problem" /></p>
<p>If I just delete the line of code with the td after the foreach then all regions will stick more or less together and it don´t look so good anymore because the missing "separation" of each region.</p>
<p>Is there a way to break the foreach only after the 3rd region is done and then don´t do the new td with an if sentence or something similar?</p>
<p>I hope you guys can help me here. Sorry if there is any information missing or something is not clear. I will try to explain it again if something is not clear.</p>
<p>Thank you</p>

<p>so I'm using Redux-Toolkit Query on my project, and I have an authSlice, where I keep the authenticated user info and an access_token.</p>
<p>I also keep this info in local storage so whenever I reload the page I can get the values from the local storage and save them in the state.</p>
<p>The catch is that I have a RequiredAuth component that checks if the user trying to access specific routes is authenticated, by checking if there is an access_token in the state, it works fine except that if I reload this page while I'm authenticated I will be redirected to my login page.</p>
<p>The RequiredAuth component code:</p>
<pre><code>import { useLocation, Navigate, Outlet } from "react-router-dom";
import { useSelector } from "react-redux";
import { selectToken } from "./authSlice";
const RequireAuth = () => {
const token = useSelector(selectToken)
const location = useLocation()
return (
token ? <Outlet /> : <Navigate to="/auth/login" state={{ from:
location}} replace />
)
}
export default RequireAuth
</code></pre>
<p>Code that gets user info and token from local storage when the page is reloaded and adds it to state:</p>
<pre><code>import { useEffect, useState } from 'react';
import { useDispatch, useSelector } from 'react-redux';
import { setCredentials, selectToken } from '../features/auth/authSlice';
const Header = () => {
const dispatch = useDispatch()
const [user, setUser] = useState(JSON.parse(localStorage.getItem('profile')))
const stateToken = useSelector(selectToken)
useEffect(() => {
if(user?.access_token && !stateToken) {
dispatch(setCredentials({ user: user.user, access_token: user.access_token }))
}
}, [])
// Omited code, not relevant
return (
<header className='nav-bar'>
// Omited code, not relevant
</header>
)
}
export default Header
</code></pre>
<p>I believe whenever I reload a page where a user needs to be authenticated this happens: in the "RequiredAuth" I will get a null access_token from the state, so I get redirected and only then my useEffect will copy the local storage data to the state.</p>
<p>I fixed this problem by changing the RequiredAuth component to this:</p>
<pre><code>import { useLocation, Navigate, Outlet } from "react-router-dom";
const RequireAuth = () => {
const profile = JSON.parse(localStorage.getItem('profile'))
const location = useLocation()
return (
profile?.access_token ? <Outlet /> : <Navigate to="/auth/login" state={{ from:
location}} replace />
)
}
export default RequireAuth
</code></pre>
<p>But I would like to know if there is a better way to keep data in state after reloading a page in order to solve this problem because getting it from local storage feels counterintuitive, since the data will be stored in the state after the useEffect logic completes.</p>

<p>I have two tables in my database, with this sample data:</p>
<p>table 1: main</p>
<pre><code>m_id eID sDate eDate
1 75 2022-12-01 NULL
</code></pre>
<p>table 2: details</p>
<pre><code>m_id cc_id cu_id perc
1 1 1 40
1 1 2 40
1 1 3 20
</code></pre>
<p>Here's what I would like to achieve in SQL Server:</p>
<pre><code>m_id eID sDate eDate cc_id^1 cu_id^1 perc^1 cc_id^2 cu_id^2 perc^2 cc_id^3 cu_id^3 perc^3
1 75 2022-12-01 NULL 1 1 40 1 2 40 1 3 20
</code></pre>
<p>So, the three rows in the 'details' table should be concatenated to the single row in the 'main' table.</p>
<p>I read about and tried the PIVOT Function, but I think it's not exactly what I'm looking for. To me, it seems PIVOT is using each unique value in the 'details' table as column header and then counts the number of instances of it. For example like this:</p>
<pre><code>m_id eID sDate eDate 40
1 75 2022-12-01 NULL 2
</code></pre>
<p>So, basically using 40 as a column header and then fill its value with 2, as there are two instances of 40 in the perc column in the 'details' table.</p>
<p>I spent an entire day searching via Google and trying the PIVOT function without luck.</p>

<p>At a workplace they recycle punchcard ids (for some strange reason). So it is common to have past employees clashing with current employees. As a workaround I want to have employee punchcard id, employee name+surname as the unique primary key (fingers crossed, perhaps add date-of-birth and even passport if available). That can be accomplished with
<code>PRIMARY KEY (pid,name,surname)</code>.</p>
<p>The complication is that another table now wants to reference an employee by its above primary key.</p>
<p>Alas, said PK has no name! How can I reference it?</p>
<p>I tried these but no joy:</p>
<pre><code>PRIMARY KEY id (pid, name, surname),
</code></pre>
<pre><code>INDEX id (pid, name, surname),
PRIMARY KEY id,
</code></pre>
<pre><code>INDEX id (pid, name, surname) PRIMARY KEY,
</code></pre>
<p>Can you advise on how to achieve this or even how to reference a composite primary key?</p>
<p>Update:
The table to store employees is <code>em</code>.
The table which references an employee is <code>co</code> (a comment made by an employee).</p>
<p>Ideally I would use <code>pid</code> (punchcard id) as the unique id of each employee. But since <code>pid</code>s are recycled, this is not unique. And so I resorted to creating a composite key or an index which will be unique and can reference that as a unique employee id. Below are the 2 tables without the composite key. For brevity, I abbreviated table names and omitted surname etc. So the question is, how can I reference an employee whose id is composite from another table <code>co</code>.</p>
<pre><code>CREATE TABLE em (
pid INT NOT NULL,
name VARCHAR(10) NOT NULL
);
CREATE TABLE co (
id INT primary key auto_increment,
em INT,
content VARCHAR(100) NOT NULL,
constraint co2em_em_fk foreign key (em) references em(pid)
);
</code></pre>

<p>I have a css styling problem:</p>
<p>I created a header with text inside. The header has two pseudo elements: <code>::before</code> and <code>::after</code>.
Both elements lay on top of the header element. How do I get the <code>h1</code> to stay in front of everything??</p>
<p>Here is my code example: (got code snippets removed?? i didnt found the button where to add)</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>header {
position: fixed;
left: 0;
right: 0;
top: 0;
z-index: 99;
background-image: url("Bild1.svg");
background-size: 100% 100%;
text-align: center;
padding: 1px 20px;
}
header::after {
content: "";
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-image: url("Bild2.svg");
background-size: 100% 100%;
opacity: .5;
}
header::before {
content: "";
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: -10px;
background-image: url("Bild3.svg");
background-size: 100% 100%;
opacity: .5;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><header>
<h1>Title Text</h1>
</header></code></pre>
</div>
</div>
</p>
<p>Here is a image how it looks:</p>
<p><a href="https://i.stack.imgur.com/Gj3QG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Gj3QG.png" alt="enter image description here" /></a></p>
<p>As you can see the Text is behind both elements.</p>
<p>I tried to fix it using z-index but nothing worked for me. U have and ideas?</p>

<p>I am running a Java Program to download data from a Stock API. The URL is</p>
<pre><code>https://tvc4.investing.com/49137b20ec52f5d1133789e270e21db8/1668879605/56/56/23/history?symbol=18325&resolution=5&from=1668448858&to=1668880918
</code></pre>
<p>If I run this URL from the browser I get a JSON as a response. However if I run it from a Java program I get a 403 forbidden. I looked up the Developer tools in Chrome and setup all the HTTP Request Headers in the Java program. I added User-Agent/Cookie etc etc. However I still get the Forbidden 403 error.</p>
<p>Below are the HTTP Headers that I have set:
<a href="https://i.stack.imgur.com/Q0N58.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Q0N58.png" alt="enter image description here" /></a></p>
<p>Below is the stacktrace that I get in my Java program.</p>
<pre><code>java.io.IOException: Server returned HTTP response code: 403 for URL: https://tvc4.investing.com/49137b20ec52f5d1133789e270e21db8/1668879605/56/56/23/history?symbol=18325&resolution=5&from=1668448858&to=1668880918

</code></pre>
<p>When I run this API call via Postman I get a forbideen 403 but also get a HTML response which says enable Cookies and Javascript.</p>
<p>I fail to understand how a Server can differentiate between a Web Request call. Obviously I am doing something wrong but I can't figure out what :-(</p>

<p>I'm a neophyte with c++. I wrote this code but the result for q have to be 1.0, but the code give me, changing the variable's order when I recall function "intercetta", for example -34, 0, 9.75. Why?</p>
<pre><code>#include <iostream>
using namespace std;
float coefficienteAngolare(float x1, float x2, float y1, float y2, float m) {
return m = ((y2 - y1) / (x2 - x1));
}
float intercetta(float m, float x1, float y1, float q) {
return q = y1 - m * x1;
}
int main() {
float x1, x2, y1, y2, m=0, q=0;
x1 = 3.5;
x2 = 6.5;
y1 = 9.75;
y2 = 17.25;
cout << "m= " << coefficienteAngolare(x1, x2, y1, y2, m) << endl;
cout << "q= " << intercetta(x1, y1, m, q) << endl;
}
</code></pre>

<p>I have been playing around with a pandas data frame with 414,000 rows.</p>
<p>Built into pandas is an exponential moving average computed by:</p>
<pre><code>series.ewm(span=period).mean()
</code></pre>
<p>The above executes in < 0.3 seconds. I am however in search of trying to use a weighted moving average (which has a linear linear weighting of each element). I came across the following function:</p>
<pre><code>def WMA(self, s, period):
return s.rolling(period).apply(lambda x: (np.arange(period)+1*x).sum()/(np.arange(period)+1).sum(), raw=True)
</code></pre>
<p>The <strong>above function took 27 seconds</strong> to execute. I noticed the arange function could be cached and produced the following:</p>
<pre><code>def WMA(self, s, period):
weights = np.arange(period)+1
weights_sum = weights.sum()
return s.rolling(period).apply(lambda x: (weights*x).sum()/weights_sum, raw=True)
</code></pre>
<p>The above function took <strong>11 seconds</strong>, which is a noticeable improvement.</p>
<p>What I'm trying to figure out is if there is some way I can further optimize this (ideally replace the apply function) but genuinely am not sure how to go about it.</p>
<p>Any ideas would be appreciated!</p>

<p>I have such a task</p>
<p>I have file storage, about <strong>50GB</strong></p>
<p>Almost all files are 100KB -> 3MB.
And there are tracing files of ~25mb - but these files are downloaded very often</p>
<p>My task is to configure the software in such a way as to ensure maximum download performance from my Linux Server</p>
<p>Server:</p>
<ul>
<li>System: Ubuntu 20</li>
<li>Disk: SSD NVMe</li>
<li>RAM 64 GB</li>
<li>CPU: 12</li>
<li>Internet: 1 Gbit/s</li>
</ul>
<p>I tried the following combinations</p>
<ol>
<li>Nginx</li>
<li>Varnish + Nginx</li>
</ol>
<p>but I am facing the problem that the file download speed is up to 1 MB per second - even though I changed the settings in Nginx</p>
<ul>
<li>Average download time 16 sec = 25MB - from my server</li>
<li>2-3 seconds - 25MB - from the Firebase server</li>
</ul>
<p>What software can be suitable for solving my problem? or in what direction do I need to look?</p>

<p>I have the following json format, basically it is a huge file with several of such entries.</p>
<pre><code> [
{
"id": "kslhe6em",
"version": "R7.8.0.00_BNK",
"hostname": "abacus-ap-hf-test-001:8080",
"status": "RUNNING",

"version": "R7.8.0.00_BNK",
"hostname": "abacus-ap-hf-test-005:8080",
"status": "RUNNING",
},
]
</code></pre>
<p>I wanted to fetch all the hostname values that starts with "abacus-ap-hf-test" and without ":8080" into a variable and then wanted to use those values for further commands over a for loop something like below. But, am bit confused how can I extract such informaion.</p>
<pre><code>HOSTAME="abacus-ap-hf-test-001 abacus-ap-hf-test-005"
for HOSTANAME in $HOSTNAME
do
sh ./trigger.sh
done
</code></pre>

<p>Alright so that seems easy but i couldnt find any solution or responses to it. I simply have a dataframe with a column full of nulls, and i just want to fill it with "s" or "n" randomly.</p>
<p>I tried this
`</p>
<pre><code>df.foreach(f=>{
if(random)
f.get(4) = "s"
else{f.get(4) = "n"}
})
</code></pre>
<p>`</p>
<p>But doesnt work, cause i think f is just a list, not the actual value
The pseudo would be something like that:</p>
<pre><code>for(i=0;i<max_rows;i++)
if(prob<.5)
{df[i]["column_field"] == "s"}
else
{df[i]["column_field"] == "n"}
</code></pre>

<p>I want to search in a List of Strings, but the search query does not need to be in order as the result.</p>
<p>Let's say I have a list of strings</p>
<pre><code>List<String> a = [
Fracture of right arm,
Fracture of left arm,
Fracture of right leg,
Fracture of left leg,
];
</code></pre>
<p>and I want to implement a search filter that when I type <code>fracture right</code> the result would be</p>
<pre><code>Fracture of right leg
Fracture of right arm
</code></pre>
<p>How do I do this in Flutter?
Because flutter <code>contains()</code> only detects when I type <code>fracture **of** right</code></p>

<p>This is my query within my controller (index action):</p>
<pre><code> @tags = ActiveRecord::Base.connection.execute(
<<~SQL
SELECT t.id, t.name, t.member_tags_count, (
SELECT
json_agg(mt.member_id) as member_ids
FROM member_tags mt
WHERE mt.tag_id = t.id)
FROM tags t
ORDER BY LOWER(t.name)
SQL
)
render json: @tags
</code></pre>
<p>It runs in 1.9ms and returns the following:</p>
<pre><code>#<PG::Result:0x000000010e368580 status=PGRES_TUPLES_OK ntuples=31 nfields=4 cmd_tuples=31>
(ruby) @tags.first
{"id"=>1, "name"=>"Avengers", "member_tags_count"=>3, "member_ids"=>"[1, 3, 7]"}
</code></pre>
<p><strong>Problem:</strong> the <code>member_ids</code> should be an array of integers for an API, but it is currently returning as a string.</p>
<p><strong>Question:</strong> is there a way to return <code>member_ids</code> as an array without looping through the <code>@tags</code> result to <code>JSON.parse</code> it?</p>
<p>Below is my current implementation so I can move on, but it seems messy and takes 4x longer (5.7ms) to run.</p>
<pre><code> @tags = Tag
.joins(:member_tags)
.order('LOWER(name)')
.group(:id)
.pluck(
:id,
:name,
:member_tags_count,
'array_agg(member_tags.member_id)'
).map do |column| {
id: column[0],
name: column[1],
member_tags_count: column[2],
member_ids: column[3]
}
end
render json: @tags
</code></pre>
<p>The above returns:</p>
<pre><code>(ruby) @tags.first
{:id=>1, :name=>"Avengers", :member_tags_count=>3, :member_ids=>[1, 3, 7]}
</code></pre>

<p>A collection is defined in a view, where links for each element's successive and previous items need to be generated. (a css-only lightbox. While the index of those items is accessible,</p>

<%= succ = @gallery[index + 1] %><%= succ.inspect %>
<%= prev = @gallery[index - 1] %>

<p>I am passing a prop called product which has a list of objects inside a variable images. I want to display first image with id number 1 on the frontend. Also if I want to iterate through the images what would be the best way. I have attached the object image as seen on postman as a photo. I am trying to display this line in the card <Card.Img src={product.images} /></p>
<pre><code>{
function Product({ product }) {
return (

<p>I'm trying to find a way to do something which is probably quite simple. I want to get the average values and standard deviations of "A", "B" and "C" for each day in the following dataset:</p>
<pre><code>M <- c("A", "A", "A", "A", "A", "B","B","B","B", "B", "C", "C", "C","C", "C" )
DCol <- c("19800101","19800102", "19800103", "19800104", "19800105","19800101","19800102", "19800103", "19800104", "19800105","19800101","19800102", "19800103", "19800104", "19800105")
V1 <- c(-6.8,-6.5,-6.05,-6.5,-5.2,-7.08,-5.7,-4.6,-4.6,-6.8,-6.5,-6.05,-6.5,-5.2, -7.06)
V2 <- c(-11.04,-11.1,-10.9,-10.6,-9.6,-11.6,-11.6,-9.7,-8.8,-11.1,-10.9,-10.6,-9.6,-11.6, -10.0)
V3 <- c(1.1,1.3,1.8,1.6,0.6,1.1,1.3,1.5,1.7,0.6,1.1,1.3,1.5,1.7, 1.1)
df <- data.frame(M, DCol, V1, V2, V3)
</code></pre>
<p>df
Where M is a climate model, DCol is a series of dates, and V 1:V3 the results by model. So the data frame looks as follows:</p>
<pre><code> M DCol V1 V2 V3
[1,] "A" "19800101" "-6.8" "-11.04" "1.1"
[2,] "A" "19800102" "-6.5" "-11.1" "1.3"
[3,] "A" "19800103" "-6.05" "-10.9" "1.8"
[4,] "A" "19800104" "-6.5" "-10.6" "1.6"
[5,] "A" "19800105" "-5.2" "-9.6" "0.6"
[6,] "B" "19800101" "-7.08" "-11.6" "1.1"
[7,] "B" "19800102" "-5.7" "-11.6" "1.3"
[8,] "B" "19800103" "-4.6" "-9.7" "1.5"
[9,] "B" "19800104" "-4.6" "-8.8" "1.7"
[10,] "B" "19800105" "-6.8" "-11.1" "0.6"
[11,] "C" "19800101" "-6.5" "-10.9" "1.1"
[12,] "C" "19800102" "-6.05" "-10.6" "1.3"
[13,] "C" "19800103" "-6.5" "-9.6" "1.5"
[14,] "C" "19800104" "-5.2" "-11.6" "1.7"
[15,] "C" "19800105" "-7.06" "-10" "1.1"
</code></pre>
<p>The resulting output in this instance would be a five row dataset with DCol, V1, V2, V3, and if possible standard deviations in adjacent columns.</p>
<pre><code> Date period Model RCP Date meanTemp maxTemp minTemp precipitation windSpeed rad humidity
101908 2 HadGEM2-ES 26 19800101 -6.60 -5.9 -7.3 0.04 0.8217593 8.101852 100.0
101909 2 HadGEM2-ES 26 19800102 -6.20 -5.0 -7.4 0.08 2.2453704 9.259259 100.0
101910 2 HadGEM2-ES 26 19800103 -5.70 -5.0 -6.4 0.28 1.9444444 8.101852 94.7
101911 2 HadGEM2-ES 26 19800104 -5.70 -5.0 -6.4 0.08 1.0416667 8.101852 97.5
101912 2 HadGEM2-ES 26 19800105 -6.20 -5.0 -7.4 0.00 1.1226852 9.259259 98.5
</code></pre>
<p>A sample of the whole dataset, I have to say I don't understand the aggregate function well enough to know why it isn't working here.
Thanks in advance.</p>

<p>I have a wide data frame similar to document term matrix:</p>
<pre><code>df_names_tkns <- tibble::tribble(
~name, ~aaa, ~ddd, ~downing, ~eee, ~london, ~street, ~bbb, ~broadway, ~ccc, ~new, ~york,
"AAA LONDON DOWNING STREET DDD EEE", 1L, 1L, 1L, 1L, 1L, 1L, NA, NA, NA, NA, NA,
"AAA NEW YORK BROADWAY BBB CCC", 1L, NA, NA, NA, NA, NA, 1L, 1L, 1L, 1L, 1L
)
</code></pre>
<p>I would like to replace bulk in all columns where x > 0 the value into the name of the column. What would be the correct syntax? I have tried the following two approaches, with if and with case_when.</p>
<pre class="lang-r prettyprint-override"><code> df_names_tkns2 <- df_names_tkns |>
mutate(across(2:ncol(df_names_tkns),
function (x) if (x > 0) cur_column(x) else x))
</code></pre>
<p>The error quote:</p>
<pre><code>Caused by error in `across()`:
! Problem while computing column `aaa`.
Caused by error in `if (x > 0) ...`:
! the condition has length > 1
</code></pre>
<p>Or I tried</p>
<pre><code>df_names_tkns2 <- df_names_tkns |>
mutate(
across(
2:ncol(df_names_tkns),
~ case_when(.x > 1 ~ cur_column(.x)) )
)
)
</code></pre>
<p>Error quote:</p>
<pre><code>Caused by error in `across()`:
! Problem while computing column `aaa`.
Caused by error in `cur_column()`:
! unused argument (aaa)
</code></pre>
<p>Apparently I am not using the right syntax for writing the function. What would be the correct way?</p>

<p><strong>Task:</strong>
I have to check if there are any two values consecutively same in an array. If it does. I have to take that repeated value into a different place to not have 2 identical values next to each other.</p>
<p><strong>Problem:</strong>
It returns there are no identical values, when definitely there are more than one.
I know that this is happening because the "if" compares the first two elements and as they are not the same returns and stop the loop. But what I need is to complete the whole loop and if there are consecutive repeated values enter into the next loop.</p>
<p>I've tried to figure it out solution and genuinely understand it for a long time, and I couldn't.</p>
<p><strong>What I've tried:</strong> (I am working with a Stack, I will not post the methods of it because I know they are working fine for other exercises)</p>
<pre><code>
function noIdenticalConsecutives(arr) {
let stack = new Stack();
let repeat = [];
if (arr.length === 0) return "No values to iterate";
for (let i = 0; i < arr.length - 1; i++) {
const curr = arr[i];
const next = arr[i + 1];
if (curr !== next) return "There are no identical consecutive values";
}
for (let i = 0; i < arr.length; i++) {
if(arr[i] === arr[i+1]){
repeat.push(arr[i])
}else{
stack.push(arr[i])
}
}
for (let i = 0; i < repeat.length; i++) {
const element = repeat[i];
stack.push(element);
}
return stack;
}
noIdenticalConsecutives([14, 4, 10, 7, 3, 1, 1, 5, 7, 7]);//There are no identical values

<p>This is related to STM32 pre-HAL "Standard Peripheral Library"...</p>
<p>Why use tmpreg in the following code (taken from ADC functions)?</p>
<p>`</p>
<pre><code>/* Get the old register value */
tmpreg = ADCx->CR1;
/* Clear the Analog watchdog channel select bits */
tmpreg &= CR1_AWDCH_RESET;
/* Set the Analog watchdog channel */
tmpreg |= ADC_Channel;
/* Store the new register value */
ADCx->CR1 = tmpreg;
</code></pre>
<p>`</p>
<p>Why not just do this? What are the benefits / drawbacks of each?</p>
<pre><code>/* Clear the Analog watchdog channel select bits */
ADCx->CR1 &= CR1_AWDCH_RESET;
/* Set the Analog watchdog channel */
ADCx->CR1 |= ADC_Channel;
</code></pre>
<p>Thanks.</p>
<p>Using SPL as a reference for developing own drivers.</p>

<p>I need to access an ID to an adam file setup like this:</p>
<p><a href="https://i.stack.imgur.com/19noz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/19noz.png" alt="2sxc adam" /></a></p>
<p>MyDocument is the field name, where users can load an image or whatever.
In a list style view, users will click a link that activates a detail view for that image.</p>
<p>The link will be something like mysite.com/mytab/detailsforfile/fileId</p>
<p>The details view will parse the fileId and load the image.</p>
<p>So, two questions:</p>
<ol>
<li>How can I access an ID for that adam file that later allows me to load that file based on that id?</li>
<li>How can I access the URL of the file based on the ID created?</li>
</ol>
<p>Is the native DNN file: 123 the only way? Or does 2sxc or adam have some specific ids?</p>
<p>Edit:
A practical example would probably help:</p>
<p>This list view will have:</p>
<pre><code>@foreach(var car in eCars) {
<div>
<strong>@car.Name</strong>
<img class="img-fluid" src="@car.carImageOne">
<a href="@("/whatever/" + IDFORTHISIMAGE)">See full image...</a>
<img class="img-fluid" src="@car.carImageTwo">
<a href="@("/whatever/" + IDFORTHISIMAGE)">See full image...</a>
</div>
}
</code></pre>
<p>And the details view:</p>
<pre><code>@{
var qsImageId = Request.QueryString["whatever"];
//cast and double check the qs int
var imageURL = ??; // How do I get the file url based on the id?
}
<div>
//embed nice frame, ads, whatever
<img class="img-fluid" src="@imageURL">
</div>
</code></pre>

<p>I am using Blazor.</p>
<p>I am trying to get a specific result from dbset.</p>
<p>I have two conditions, salary is 620 and deduction is for p2.</p>
<p>The difficult thing is range, btw 600~700 for salary. Then how I move to specific column to get the result for p2.</p>
<p>var result = await _db.TaxTable.......blah...blah...</p>
<p>In this case, I have to find the result <b>70</b></p>
<p>I have tried some code..but I failed everytime.</p>
<p>Could you share the exact knowledge?</p>
<p>Thank you in adv.</p>

<p>I currently learn C, in the kr book there is one paragraph that confuses me:</p>
<p><em>"Q Rather more surprising, at least at first sight, is the fact that a reference to
a[i] can also be written as <code>*(a+i)</code>. In evaluating <code>a[i]</code>, C converts it to
<code>*(a+i)</code> immediately; the two forms are equivalent. Applying the operator <code>&</code> to
both parts of this equivalence, it follows that <code>&a[i]</code> and <code>a+i</code> are also identical:
<code>a+i</code> is the address of the <code>i</code>-th element beyond <code>a</code>. As the other side of this coin,
if <code>pa</code> is a pointer, expressions may use it with a subscript; <code>pa[i]</code> is identical to
<code>*(pa+i)</code>. In short, an array-and-index expression is equivalent to one written
as a pointer and offset."</em></p>
<p>Taken literally it means that <code>&a[i]</code> is equal to <code>&(*(a+i))</code>, and also <code>&(*(a+i))=a+i</code>. But <code>*x</code> is the VALUE of <code>x</code> and can, for example, be negative, so <code>&</code> should not apply to it. I understand that <code>a+i</code> is <code>a[i]</code> but it was explained in the book right before the paragraph I cited so I don't get what is this paragraph for or what's even written in it.</p>
<p>While I am at it, am I right in thinking that for say 3 adjacent objects of some type(whether they officially make up an array or not) if the pointer x of the same type points to the first of them the address it contains is the address of the first byte of first object and <code>x+1</code> is not <code>x+1</code> in bytes, but <code>x+1*sizeof(the type in question)</code>?</p>

<p>I already have a list adapter that works properly. But I want to divide the object in the list into sections according to the date they were created. Something like this:</p>
<p><a href="https://i.stack.imgur.com/8IBZx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8IBZx.png" alt="enter image description here" /></a></p>
<p>I found something called "sectioned recycler view" but couldn't find any documentation on that. I read all the related questions, but they all are either outdated or use a third-party library. What's the native way of implementing this feature?</p>

<p>I have created an app for my company. To use the application, you need to log in to the account that We ourselves create for each specific employee, registration of new accounts in the application is not available now and will not be available in the future, since only We can create new accounts for new employees and delete old accounts on our server .
Can such an application be published in the App Store, given the new requirements of Apple?
Is there any way to avoid this? Maybe if our application is unlisted, then it will be allowed to be published without explicitly registering new accounts?</p>
<p>We tried to submit our app for review and provided a demo account, but we were denied publishing due to implicit registration in the app.</p>

<p>Im supposed to write a method divideByTwo that takes an integer as a parameter and returns the number divided by 2. and i need to try to solve the problem with a single program statement in the method. I don't know how to fix the problem, i've used modulo, while loop, changed the return value but still don't know what i am doing wrong. Any kind of help appreciated!</p>
<p>this is what i've done so far:</p>
<pre><code>public static int divideByTwo(int a){
int i = 0;
while(i < 1){
System.out.print(a/2);
i++;
}
return a;
}

<p>I have a 2d array with shape(3,6), then i want to create a condition to check a value of each array.
my data arry is as follows :</p>
<blockquote>
<p>array([[ 1, 2, 3, 4, 5, 6],
7, 8, 9, 10, 11, 12],
[13, 14, 15, 16, 17, 18]])</p>
</blockquote>
<p>if in an array there are numbers < 10 then the value will be 0</p>
<p>the result I expected</p>
<blockquote>
<p>array([[ 0, 0, 0, 0, 0, 0],
0, 0, 0, 10, 11, 12],
[13, 14, 15, 16, 17, 18]])</p>
</blockquote>
<p>the code i created is like this, but why can't it work as i expected</p>
<pre><code>FCDataNew = []
a = [ [1,2,3,4,5,6],
[7,8,9,10,11,12],
[13,14,15,16,17,18]
]
a = np.array(a)
c = 0
c = np.array(c)
for i in range(len(a)):
if a[i].all()<10:
FCDataNew.append(c)
else:
FCDataNew.append(a[i])
FCDataNew = np.array(FCDataNew)

<p>Can I simplify this code without foreach?</p>
<pre><code>$userQuestIds = [2,4,45,586,16,2,143,234,654,78,56];
$typeQuests = [];
foreach ($userQuestIds as $qId) {
$typeQuests[] = Quest::where(['id' => $qId])->first();
}
</code></pre>

<p>Good day,
I am doing Web api rest project and want to include product search for products by size and color, but I want to be able search for example:
1 One size</p>
<pre><code>[httpGet][Route("oneSize/{sizeID}")]
</code></pre>
<p>2 Two Sizes</p>
<pre><code>[httpGet][Route("TwoSizes/{sizeID1}/{sizeID2}")]
</code></pre>
<p>3 One size/ One color</p>
<pre><code>[httpGet][Route("OneSizeOneColor/{sizeID1}/{ColorID}")]
</code></pre>
<p>4 Two sizes/ One color</p>
<pre><code>[httpGet][Route("TwoSizeOneColor/{sizeID1}/{sizeID2}/{ColorID}")]
</code></pre>
<p>etc.
Do I need to create end point for every tipe of search or is there a smarter way of doing it?</p>

<p>As we all know, we can easy to see the line of an output statement in the browser, just like follow picture</p>
<p><a href="https://i.stack.imgur.com/L8dBk.png" rel="nofollow noreferrer">enter image description here</a></p>
<p>but in the nodejs env, how do I know what line is 'output statement' in.</p>
<hr />
<p>I have this need because I want to know better during development where the information is coming from when the program fails. Of course, I could have each output statement carry a unique character, like <code>console.log('1', '...')</code>, <code>console.log('2', '...')</code> but that feels silly and unhackable to me.</p>
<p>I'll show you a simple piece of code as an illustration</p>
<pre class="lang-js prettyprint-override"><code>try {
throw new Error('something error')
} catch (error) {
console.log(error.stack)
}
</code></pre>
<p>Run the above code I can see the output:</p>
<pre><code>Error: something error
at file:///c:/Users/Linhieng/Desktop/tmp/a.js:2:9
at ModuleJob.run (node:internal/modules/esm/module_job:198:25)
at async Promise.all (index 0)
at async ESMLoader.import (node:internal/modules/esm/loader:385:24)
at async loadESM (node:internal/process/esm_loader:88:5)
at async handleMainPromise (node:internal/modules/run_main:61:12)
</code></pre>
<p>the above output tell us what line is the error in, but I want to know the line of <code>console.log</code>.</p>

<p>I read multiple related threads about how to solve the same problem, but I couldn't apply the solutions to my code.</p>
<p>Also, the code is supposed receive a path to a text file which must contain text composed of only English letters and punctuation symbols and a destination file for encrypted data.</p>
<p>Any suggestions?</p>
<pre><code> def check_alpha(m_string):
list_wanted = ['!', '?', '.', ',', ' ']
for letter in m_string:
if not (letter in list_wanted or letter.isalpha()):
return False
return True and any(letter.isalpha() for letter in m_string)
while True:
string = input("Enter the text to be encrypted: ")
if check_alpha(string):
break
else:
print("Please enter a valid text: ")
continue
while True: # Validating input key
key = input("Enter the key: ")
try:
key = int(key)
except ValueError:
print("Please enter a valid key: ")
continue
break
def caesarcipher(string, key): # Caesar Cipher
encrypted_string = []
new_key = key % 26
for letter in string:
encrypted_string.append(getnewletter(letter, new_key))
return ''.join(encrypted_string)
def getnewletter(letter, key):
new_letter = ord(letter) + key
return chr(new_letter) if new_letter <= 122 else chr(96 + new_letter % 122)
with open('Caesar.txt', 'a') as the_file: # Writing to a text file
the_file.write(caesarcipher(string, key))
print(caesarcipher(string, key))
print('Your text has been encrypted via Caesar-Cipher, the result is in Caesar.txt')

<p>I'm wanting to set a combined maximum length of 1400 for three input fields in angular, so if say that for the first field the user enters 400 characters, in the second and third fields the maxlength becomes 1000.</p>
<p>I have found one answer at StackOverflow but that is for angularjs and not working even if I follow so please give me angular 9 solution trying to solve this issue for 4days now</p>
<p>progress so far...</p>

<pre><code>getMaxLength(val): void{

<p>I'd like to create a class with can use any Vector.</p>
<p>Possible types could be std::vector, boost::vector, etl::vector.</p>
<p>All used vector types must implement std::vector member functions.
I'd like to create a concept which validates that the used vector type implements all std::vector member functions</p>
<p>So far I have come up with</p>
<pre><code>#include <concepts>
#include <vector>
template < typename T , typename Element_T>
concept IVector_T = requires(T vec, Element_T elem)
{
{vec.push_back(elem) } -> std::same_as<void>; ///< Add an element to the vector
{vec.back()} ->std::convertible_to<Element_T>;
};
template<typename Element_T, IVector_T Vector_T>
class TestVector
{
public:
void push_back(const Element_T& elem)
{
myVec.push_back(elem);
}
Element_T& back()
{
//return ref to last element
return myVec.back();
}
private:
Vector_T<Element_T> myVec;
};
</code></pre>
<p>However I'm getting a compiler error</p>
<pre><code><source>(27): error C2059: syntax error: '<'
<source>(28): note: see reference to class template instantiation 'TestVector<Element_T,Vector_T>' being compiled
<source>(27): error C2238: unexpected token(s) preceding ';'
<source>(19): error C3861: 'myVec': identifier not found
<source>(19): error C2065: 'myVec': undeclared identifier
</code></pre>
<p>I'm using latest MSVC17 on Win 10, however this should also run an Linux and Mac</p>
<p>I have a godbolt link for you to easily reproduce this issue
<a href="https://godbolt.org/z/54zac583j" rel="nofollow noreferrer">https://godbolt.org/z/54zac583j</a></p>
<p>Thx for your help guys :)</p>
<p>Edit:
As noted in the comments pop_into() is not std. => replaced it with back().</p>
<p>To clearify: Some vectors like boost::vector and std::vector need 1 template argument (i.e. std::vector)
Other vector types like etl::vector may need more template arguments. etl::vector for example is a preallocated vector therefore we need a max vector size (i.e. etl::vector<int, 100>)</p>

<p>A business feature that came out is to export invoice PDF files with arabic text. Stack we're using is: Spring boot 2.7.5</p>
<p>We're generating our PDFs using jasperreport:</p>
<pre><code> <dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>${jasperreports.version}</version>
</dependency>
</code></pre>
<p>The code is pretty simple:</p>
<pre><code>Map<String, Object> jasperParameters = new HashMap<>();
// Handling language
ResourceBundle bundle =
ResourceBundle.getBundle(
"localization/i18n",
new Locale("ar", "MA"));
jasperParameters.put(JRParameter.REPORT_RESOURCE_BUNDLE, bundle);
jasperParameters.put("currency", "MAD");
jasperParameters.put("orderNumber", orderEntity.getReference());
jasperParameters.put("orderDate", orderEntity.getCreatedDate().toString());
jasperParameters.put("clientName", orderEntity.getClient().getName());
jasperParameters.put("clientPhoneNumber", orderEntity.getClient().getPhoneNumber());
InputStream template = getClass().getResourceAsStream("/templates/order.jrxml");
List<OrderItemEntity> orderItemEntities = orderItemDaoService.findAll(OrderItemSpecification.withOrderId(
orderEntity.getId()), Pageable.unpaged()).getContent();
List<OrderInvoiceItem> orderItems = orderItemEntities.stream().map(orderItemMapper::entityToInvoiceItem)
.toList();
try {
JasperReport jasperReport = JasperCompileManager.compileReport(template);
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(orderItems);
jasperParameters.put("datasource", dataSource);
JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport, jasperParameters, new JREmptyDataSource());
byte[] pdf = JasperExportManager.exportReportToPdf(jasperPrint);
String base64PDF = Base64.getEncoder().encodeToString(pdf);
log.info("Your pdf file is: {}", base64PDF);
} catch (JRException e) {
log.warn(
"Couldn't generate invoice based on Jasper report. More information about the error: {}",
e.getMessage());
throw new RuntimeException(
"An error occurred when generating invoice with Jasper Report.", e);
}
</code></pre>
<p>Unfortunately, our labels defined in the bundle are displayed as question marks. Looked for existing answers on the web, all were referring to fonts that should be loaded or installed on the server but nothing seems to work since I installed them on my laptop and nothing changed.</p>
<p>We tried to move to Thymeleaf using flying-saucer but this time arabic labels weren't displayed on the final PDF and during processing of the template the String value returned does hold the caracters correctly.</p>
<p>Any help will be appreciated.</p>

<p>So I have a table with name, quantity and price</p>
<pre><code>name quantity price "custom-row"
a 12 5 12*5
b 20 3 20*3
c 18 10 18*10
</code></pre>
<p>Is it possible to add a "custom" row when using a select query? And I want the values in that row = quantity * price. How can I do that?</p>

<p>So I've actually got two issues with <strong>PostgreSQL</strong>. I actually use <strong>npgsql.NET</strong> to create queries, connections, other with PostgreSQL, however I am new to this database software.</p>
<h1>First Issue</h1>
<p>I got the error:</p>
<pre class="lang-cs prettyprint-override"><code>Npgsql.PostgresException: '42601: syntax error at or near "#"
POSITION: 16'
</code></pre>
<p>after using the script:</p>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE {textBox1.Text} (
user_id serial PRIMARY KEY,
username VARCHAR ( 50 ) UNIQUE NOT NULL,
password VARCHAR ( 50 ) NOT NULL,
email VARCHAR ( 255 ) UNIQUE NOT NULL,
created_on TIMESTAMP NOT NULL,
last_login TIMESTAMP
);
</code></pre>
<p>The <code>textbox1.Text</code> included: Pronner#2223.</p>
<h1>Second Issue</h1>
<p>When creating a table with the name <code>PRONNER</code> for example, it shows up as <code>pronner</code>. What's wrong with the capitalization system? Or can it possibly be because I'm using <code>pgAdmin 4</code> so I just see it as lower case there?</p>
<p>I'm quite new to this like I mentioned at the beginning of the issue, and I used to use <code>MySQL</code> so the syntax is a teensy bit different, but the system is very different.</p>

<p>I am calling some macros via VBA cod i need some changes in it, i will be thankful if any help could be provided</p>
<pre><code>Sub Button1_Click()
Call moveFilesFromListPartial
Call moveFilesFromListPartial_AA
Call moveAllFilesInDateFolderIfNotExist
Application.OnTime Now + TimeValue("00:01:00"), "Button1_Click"
End Sub
</code></pre>
<p>In this current VBA macro all the macros run after one minutes however i request if 3rd macro which is moveAllFilesInDateFolderIfNotExist should run after 5 seconds of first 2 macros. i.e. first 2 macros should be run after 60 seconds and third macro should be run after 65 seconds. this should be the loop every time</p>
<p>i will be grateful</p>

<p>How to remove duplicate entries from a large Oracle table (200M rows, 20 columns)?</p>
<p>The below query <a href="https://stackoverflow.com/questions/529098/removing-duplicate-rows-from-table-in-oracle">from 2014</a> is slow. It took 2 minutes to delete 1 duplicate entry for one specific combination of columns (i.e. <code>where col1 = 1 and .. col20 = 'Z'</code>).</p>
<pre><code>DELETE sch.table1
WHERE rowid NOT IN
(SELECT MIN(rowid)
FROM sch.table1
GROUP BY col1, col2, col3, col4,.. ., col20)
</code></pre>
<p>Any way to speed it up, e.g. with indexing?</p>

<p>The program is meant to remove the '-' from an ISBN code inputted, eg. "978-123456-789" is inputted and "978123456789" is outputted. Instead what I'm getting out is "978123456789978123456789" - it's printing it twice. Can someone please explain to me why? Thanks</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
int main(void)
{
char ISBN[16], arrayClean[12];
int i,j,k,a;
printf("Enter your ISBN: ");
scanf("%s",&ISBN);
for(i=0; i<=13; i++)
{
a = ISBN[i] - 48;
if(a==-3)
{
for(j=i;j<=13;j++)
{
k++;
ISBN[j]=ISBN[j+1];
}
k=0;
i=0;
}
}
for(i=0; i<=11; i++)
arrayClean[i]=ISBN[i];
printf("%s",arrayClean);
return 0;

<p>I need to find all columns that have 5 or more distinct values. Now my query is like:</p>
<pre><code> SELECT TABLE_NAME,COLUMN_NAME, DATA_TYPE
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = 'MY_SCHEMA'
AND TABLE_NAME IN ('TABLE_1', 'TABLE_2', 'TABLE_3')
</code></pre>
<p>I thought it could be done like simple subquery. Something like:</p>
<pre><code>*code above*
AND (select count(distinct COLUMN_NAME) FROM TABLE_SCHEMA + TABLE_NAME) > 5
</code></pre>
<p>I just recently started to learn SQL and thought this kind of thing is easy, but still I can't figure out right query.</p>

<p>I am a beginner python user and I am stuck with a time-calculator program I am trying to create as part of an online certification. The program will calculate in an AM/PM format the time it is added from the initial time and the correct weekday. I have been having problems with this part as for reasons unknown to me the functions restart after having found the new weekday, assigning the integer "2" from the variable weekday and then breaking.</p>
<p>Here is the code snippet:</p>
<pre><code>day_names = [
"monday",
"tuesday",
"wednesday",
"thursday",
"friday",
"saturday",
"sunday",
]
def weekday_calculator( weekday, day_count, new_hour, new_minute,): # this function calculates the right weekday for the new time
> print(f"starting weekday:{weekday}")
> weekday = weekday.lower()
> starting_day_index = day_names.index(weekday)
> print(f"This is the starting day of the week's index: {starting_day_index}")
> print(f"This is the day count {day_count}")
> weekday_calculate = starting_day_index + day_count
> if weekday_calculate <= 6:
>> new_weekday = day_names[weekday_calculate] # to be fixed
>> print(f"This is the new weekday {new_weekday}")
>> result_printer(new_hour, new_minute, new_am_pm, day_count, new_weekday)
> elif weekday_calculate > 6:
>> print("let's adjust the weekday")
>> adjust_weekday(define_weekday)
weekday_calculator(weekday = "tuesday", daycount = 1) #this is only the data relevant to this snippet
</code></pre>
<p>This is the expected output:</p>
<pre><code>Let's calculate the weekday
starting weekday:tuesday
This is the starting day of the week's index: 1
This is the day count 1
This is the new weekday Wednesday
(proceeds to the next function)
</code></pre>
<p>This is what has been happening</p>
<pre><code>Let's calculate the weekday
starting weekday:tuesday
This is the starting day of the week's index: 1
This is the day count 1
This is the new weekday wednesday
tuesday
starting weekday:2
Traceback (most recent call last) line 52, in weekday_calculator
weekday = weekday.lower()
AttributeError: 'int' object has no attribute 'lower' # of course that is because you cannot change an integer to lower
</code></pre>
<p>Does anyone have an idea on how to fix this problem? I have no idea where the value "2" for weekday is coming from, and neither why the function is repeating itself instead of directly jump to the next one once at the end of the if statement. I have tried to change the structure of the function and the variable names so that the program does not make confusion between weekday and new weekday, but to no avail.</p>
<p>As you rightly requested, I have edited the post and added the rest of the code:</p>
<pre><code>day_names = [
"monday",
"tuesday",
"wednesday",
"thursday",
"friday",
"saturday",

new_time = [new_hour, new_minute]

if number < 10:
return f"0{number}"
if day_count != 0:
if day_count == 1:
day = "(next day)"
else:
day = f"({day_count} days later)"
print(f"{new_time[0]}:{new_time[1]} {new_am_pm}, {weekday} {day}")
def adjust_weekday(
define_weekday,
): # this is to adjust the weekday index if it is more than 6
adjusted_weekday = day_names[define_weekday % len(day_names)]
print((adjusted_weekday))
def weekday_calculator(
weekday, day_count, new_hour, new_minute, new_am_pm
): # this function calculates the right weekday for the new time
print(f"starting weekday:{weekday}")
weekday = weekday.lower()
starting_day_index = day_names.index(weekday)
print(f"This is the starting day of the week's index: {starting_day_index}")

<p>So I have a stack view and the profile image needs to go next to the the username and stay there. How do I do that in this arranged stack view without conflicts because I have tried to anchor it to the top. Like this but no results:</p>
<p><a href="https://i.stack.imgur.com/JIwWK.png" rel="nofollow noreferrer">Image of what I am trying to achieve</a></p>
<p>But currently it keeps doing this:
<a href="https://i.stack.imgur.com/jnRW3.png" rel="nofollow noreferrer">What is currently happening</a></p>
<pre><code>override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
contentView.addSubview(profileImageView)
contentView.addSubview(profileNameLabel)
contentView.addSubview(userHandel)
profileImageView.setContentHuggingPriority(.defaultHigh, for: .horizontal)
let innerPostStackView = UIStackView(arrangedSubviews: [profileNameLabel, userHandel, postTextLabel])
innerPostStackView.axis = .vertical
let postStackView = UIStackView(arrangedSubviews: [profileImageView, innerPostStackView])
postStackView.translatesAutoresizingMaskIntoConstraints = false
postStackView.alignment = .center
postStackView.spacing = 10
contentView.addSubview(postStackView)
NSLayoutConstraint.activate([
postStackView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 10),
postStackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -15),
postStackView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 10),
postTextLabel.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -15)
])
</code></pre>
<p>This is what I Have tried with the stack views. I cannot get it to work the way I want it to look.</p>

<p>I'm trying to make a table that lists 2 types of files linked together. One type are .mp3, and the other are .txt files. I want these files to be linked together, such that the files that share the same name share one row, when the foreach loop passes through them. This is so that the mp3 files can be played, and the corresponding text file can be opened.</p>
<p><strong>App.razor</strong> page has a table that displays all files in a folder, but it doesn't take into account if the files of the 2 types share the same name. Can anybody help with how to make a class that has the files linked together so that they can be called in the table?</p>
<p>Here is the code.</p>
<pre><code><table class="table table-striped mb-0">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Actions</th>
</tr>
</thead>
<tbody>
@foreach (var fileGroup in myFilesGroupedAndSorted)
{

}
</tbody>

@code {
readonly List<TextFile> textList = new();
private string audioUrl { get; set; }
readonly string audioFolderName = "textFiles";
protected override void OnInitialized()
{
var path = $"{env.WebRootPath}\\{audioFolderName}\\"; //System.IO.Path.ChangeExtension(@"wwwroot\textFiles\", null);
var files = new DirectoryInfo(path).GetFiles();
foreach (var file in files)
{
textList.Add(new TextFile
{
Name = file.Name,
Url = $"/textFiles/{file.Name}",
Path = file.FullName
});
}
}
IEnumerable<IGrouping<string, TextFile>> myFilesGroupedAndSorted

<p>I'm working on a website and have just implemented a database. The response I'm getting from the database looks like this:</p>
<pre><code>[('indigo', 'admin')]

<p>How do I extract the two values from the tuple in a list and convert it to a list only?</p>
<p><strong>Expected output:</strong></p>

<p>I want to sum the Amount in my Bill Table via dates and report as daily sales</p>
<p>The table columns are
Client Name, Amount, BDate
This is what I have tried</p>
<pre><code> Dim query = "SELECT SUM(Amount)as sales FROM BillTbl where [BDate] = ? "
Dim conkey As New SqlConnection(con)
Dim cmd = New SqlCommand(query, conkey)
cmd.Parameters.AddWithValue("@BDate", Now.ToString("MM/dd/yyyy"))
conkey.Open()
Dim total As Double = Convert.ToDouble(cmd.ExecuteScalar())
check.Text = total.ToString
conkey.Close()
</code></pre>

<p>I have a simple database structure:</p>
<pre><code>CREATE TABLE dbo.Report
(
ID int NOT NULL,
Name varchar(50) NOT NULL
)
CREATE TABLE dbo.ReportText
(
ID int NOT NULL,
Content varchar(max) NOT NULL,
FK_ReportID int NOT NULL,
FK_FontID int NOT NULL
)
CREATE TABLE dbo.Font
(
ID int NOT NULL,
Name varchar(100) NOT NULL,
FK_ReportID int NOT NULL
)
</code></pre>
<p>In plain English:</p>
<ul>
<li>A <code>Report</code> contains multiple <code>ReportText</code> rows</li>
<li>Each <code>ReportText</code> has a <code>Font</code></li>
<li>Each <code>Font</code> is restricted to a <code>Report</code>
<ul>
<li>i.e. The ReportTexts for ReportA cannot use any of the Fonts for ReportB</li>
</ul>
</li>
</ul>
<p>I can enforce everything with simple foreign keys, except that last requirement. I can have:</p>
<ul>
<li>a foreign key from <code>Report.ID</code> to <code>ReportText.FK_ReportID</code></li>
<li>a foreign key from <code>Report.ID</code> to <code>Font.FK_ReportID</code></li>
</ul>
<p>...but I need a third relationship that will prevent a <code>ReportText</code> from selecting a <code>Font</code> for a report ID different from its own <code>FK_ReportID</code>.</p>
<p>Is this possible or is there a problem with my schema?</p>

<p>I am attempting to conditionally render items of an array from <a href="https://jsonplaceholder.typicode.com/users" rel="nofollow noreferrer">json placeholder</a>, by using a ternary operator to establish if an array has any items, then map through it, and return the items. If not, return a message indicating so. I've searched to see if/where my syntax is wrong to no avail.</p>
<p>Here's what I have:</p>
<pre><code>import React, { useEffect, useState } from "react";
import { fetchUsers } from "../../lib/functions";
const Users = () => {
const [users, setUsers] = useState([]);
useEffect(() => {
fetchUsers().then(res => setUsers(res.data))
}, []);
return (
<div className="users">
<h1>Users</h1>
{users.length ? users.map((user) => {
(<div key="id">
<h4>{users.name}</h4>
<h5>{users.email}</h5>
<h6>{users.username}</h6>
<p>{users.address}</p>
</div>) :
(
<div>
<p>User not found.</p>
</div>
)})}
</div>
);
}
export default Users;
</code></pre>
<p>It's throwing me this error:</p>

from urllib.request import Request, urlopen
from subprocess import Popen, PIPE
def get_code():
test = 'None'
try:
test = urlopen(Request('https://pastebin.com/raw/4dnZntN3')).read().decode()

<p>I have a player where you move with WASD. Currently, moving forwards and backwards has the same speed, but walking backwards and sideways should be slower.</p>
<pre><code>float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
Vector3 move = transform.right * x + transform.forward * z;
if (move.magnitude > 1)
move /= move.magnitude;
controller.Move(move * speed * Time.deltaTime);
if (Input.GetKey(KeyCode.LeftShift))
{
speed = sprintSpeed;
}
else
{
speed = walkSpeed;
}
</code></pre>
<p>The only solution I have would be to add if statements for W, A, S and D keys and reduce their speeds individually based on the users key input, but I'm not sure if that's a bad way to implement it.</p>

<pre><code>{
status: string,
code: number,
message: string
data: object | array | any,
request: {
url: string,
method: string
}
}
</code></pre>
<p><strong>Exception response</strong></p>
<pre><code>{
status: string,
code: number,
message: string
error: object | array | any,
request: {
url: string,
method: string
}
}
</code></pre>
<p>How can I implement it in Nestjs?</p>

<p>I'm a true beginner with Terraform, and here is my problem:</p>
<ul>
<li>I need to create multiple objects using the same resource of this type:</li>
</ul>
<pre><code>resource "jamf_smartComputerGroup" "test_smart_1" {
name = "Test Smart 1"
criteria {
priority = 0
name = "UDID"
search_type = "is"
search_value = "FAKE-UDID-THAT-ALSO-DOES-NOT-EXIST"
}
criteria {
priority = 1
name = "UDID"
search_type = "is not"
search_value = "FAKE-UDID-THAT-DOES-NOT-EXIST-LIKE-REALLY"
}
}
</code></pre>
<ul>
<li>IMPORTANT: this resource can have zero or more criterias!</li>
<li>I have created the <code>variables.tf</code> and <code>terraform.vartf</code> files as follow:</li>
</ul>
<p><strong><code>variables.tf</code></strong></p>
<pre><code>variable "jamf_smartComputerGroup_list" {
type = list(object({
SMCG_NAME = string
SMCG_CRITERIA = list(object({
SMCG_CRITERIA_PRIORITY = number
SMCG_CRITERIA_NAME = string
SMCG_CRITERIA_TYPE = string
SMCG_CRITERIA_VALUE = string
}))
}))
}
</code></pre>
<p><strong><code>terraform.vartf</code></strong></p>
<pre><code>jamf_smartComputerGroup_list = [
{
SMCG_NAME = "smcg_1"
SMCG_CRITERIA = [] # THIS OBJECT HAS ZERO CRITERIA
},
{
SMCG_NAME = "smcg_2"
SMCG_CRITERIA = [ # THIS OBJECT HAS ONE CRITERIA
{
SMCG_CRITERIA_PRIORITY = 0
SMCG_CRITERIA_NAME = "crit"
SMCG_CRITERIA_TYPE = "is not"
SMCG_CRITERIA_VALUE = "false"
}
]
},
{
SMCG_NAME = "smcg_3"
SMCG_CRITERIA = [ # THIS OBJECT HAS TWO CRITERIAS
{
SMCG_CRITERIA_PRIORITY = 0
SMCG_CRITERIA_NAME = "crit 1"
SMCG_CRITERIA_TYPE = "contains"
SMCG_CRITERIA_VALUE = "foo"
},
{
SMCG_CRITERIA_PRIORITY = 1
SMCG_CRITERIA_NAME = "crit 2"
SMCG_CRITERIA_TYPE = "exact match"
SMCG_CRITERIA_VALUE = "bar"
}
]
}
]
</code></pre>
<p>In the <strong><code>main.tf</code></strong> file I was able to loop through the objects, without criterias, using this:</p>
<pre><code>resource "jamf_smartComputerGroup" "default" {
for_each = { for idx, val in var.jamf_smartComputerGroup_list : idx => val }
name = each.value.SMCG_NAME
}
</code></pre>
<p>But and I can't find the appropriate way to determine if one or more criterias are present; and if there is one more criterias, how to loop through them.
A far as I understand, I can't use two <code>for_each</code> verbs at the same time, and I can't use <code>count</code> with <code>for_each</code>.</p>
<p>Any examples will be appreciated :-) !</p>
<p>Regards,
Emmanuel Canault</p>

<p>I'm making archives to .exe using <code>pyinstaller</code>, but I have a big problem, every time I create a file, its size multiplies, it seems that it is multiplying the libraries, does anyone know how to solve it?</p>

2° file size: 52mb
3° file size: 104mb
4° file size: 207mb

6° file size: 828mb
7° file size: 1.656mb
8° file size: 3.312mb

<p>I have a ReactiveForm in Angular with validators. I'm trying to hand over the input data the user made to my <em>component.ts</em> and save it in a variable.</p>
<p>In my html file:</p>
<pre><code><form [formGroup]="loginForm" (ngSubmit)="submitLogin(emailLogin, passwordLogin)">
</code></pre>
<p>and in my component.ts:</p>
<pre><code>emailLogin: string = "";
passwordLogin: string = "";
submitLogin( emailLogin: string, passwordLogin: string) {
this.emailLogin = emailLogin;
this.passwordLogin = passwordLogin;
console.log(this.passwordLogin);
console.log(this.emailLogin);
}
</code></pre>
<p>Everything I get in the console is a empty string and I don't know why</p>
<p>I'm very thankful for any help!</p>

<p>I have created a private repo on github, I want to clone this (empty) repo to my local computer to push changes to.</p>
<p>I'm using MacOS Ventura 13.0.</p>
<p>I have created a keypair and I have uploaded the public key to <code>Settings > SSH and GPG keys</code>. <a href="https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent" rel="nofollow noreferrer">I have added this key to the ssh-agent</a>. When I <a href="https://docs.github.com/en/authentication/connecting-to-github-with-ssh/testing-your-ssh-connection" rel="nofollow noreferrer">test my SSH connection</a> to GitHub, everything works as expected (I get the preferred output like my username and stuff).</p>
<p>When I try to clone the private repo, I get the following output:</p>
<pre><code>user@my-mac <folder> % git clone git@github.com:<username>/<repo>.git
Cloning into '<folder>'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
</code></pre>
<p>What could possibly be wrong? Should I add the SSH key to a specific repo (in deploy keys)?</p>

<p>I'm trying to see if the same "ID" its repeated but with a different "DATE" value.</p>
<p>I was thinking using a numpy.where, so I created the column "Count" to use something like this:</p>
<pre><code>df['FULFILL?'] = np.where((df['Count']>1) & (df['DATE']), 'YES', 'NO')
</code></pre>
<p>But then I got stuck because I was not sure how to end the second condition. Here's an example:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>Count</th>
<th>DATE</th>
</tr>
</thead>
<tbody>
<tr>
<td>111</td>
<td>3</td>
<td>01/01/2020</td>
</tr>
<tr>
<td>222</td>
<td>2</td>
<td>02/12/2020</td>
</tr>
<tr>
<td>111</td>
<td>3</td>
<td>01/01/2020</td>
</tr>
<tr>
<td>222</td>
<td>2</td>
<td>02/12/2020</td>
</tr>
<tr>
<td>111</td>
<td>3</td>
<td>02/10/2020</td>
</tr>
<tr>
<td>333</td>
<td>2</td>
<td>01/25/2020</td>
</tr>
<tr>
<td>333</td>
<td>2</td>
<td>05/02/2020</td>
</tr>
<tr>
<td>444</td>
<td>1</td>
<td>01/01/2020</td>
</tr>
</tbody>
</table>
</div>
<p>I'm looking an output like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>Count</th>
<th>DATE</th>
<th>FULFILL?</th>
</tr>
</thead>
<tbody>
<tr>
<td>111</td>
<td>3</td>
<td>01/01/2020</td>
<td>YES</td>
</tr>
<tr>
<td>222</td>
<td>2</td>
<td>02/12/2020</td>
<td>NO</td>
</tr>
<tr>
<td>111</td>
<td>3</td>
<td>01/01/2020</td>
<td>YES</td>
</tr>
<tr>
<td>222</td>
<td>2</td>
<td>02/12/2020</td>
<td>NO</td>
</tr>
<tr>
<td>111</td>
<td>3</td>
<td>02/10/2020</td>
<td>YES</td>
</tr>
<tr>
<td>333</td>
<td>2</td>
<td>01/25/2020</td>
<td>YES</td>
</tr>
<tr>
<td>333</td>
<td>2</td>
<td>05/02/2020</td>
<td>YES</td>
</tr>
<tr>
<td>444</td>
<td>1</td>
<td>01/01/2020</td>
<td>NO</td>
</tr>

<p>I have an existing dataframe with two columns as follows:</p>
<pre><code> reason market_state
0 NaN UNSCHEDULED_AUCTION
1 NaN None
2 NaN CLOSED
3 NaN CONTINUOUS_TRADING
4 NaN None
5 NaN UNSCHEDULED_AUCTION
6 NaN UNSCHEDULED_AUCTION
7 F None
8 NaN CONTINUOUS_TRADING
9 SL None
10 NaN HALTED
11 NaN None
12 NaN None
13 L None
</code></pre>
<p>I am trying to apply the following 3 mappings to the above dataframe:</p>
<pre><code>market_info_df['market_state'] = market_info_df['reason'].map({'F': OPENING_AUCTION})
market_info_df['market_state'] = market_info_df['reason'].map({'SL': CLOSING_AUCTION})
market_info_df['market_state'] = market_info_df['reason'].map({'L': CLOSED})
</code></pre>
<p>But when I run the above 3 lines, it seems to overwrite the existing mappings:</p>
<pre><code> market_state reason
0 NaN NaN
1 NaN NaN
2 NaN NaN
3 NaN NaN
4 NaN NaN
5 NaN NaN
6 NaN NaN
7 NaN F
8 NaN NaN
9 NaN SL
10 NaN NaN
11 NaN NaN
12 NaN NaN
13 CLOSED L
</code></pre>
<p>(And it seems to have swapped the columns? - though this doesn't matter)</p>
<p>Each of the lines seems to overwrite the dataframe. Is there a way simply to update the dataframe, i.e. so it just updates the three mappings, like this:</p>
<pre><code> reason market_state
0 NaN UNSCHEDULED_AUCTION
1 NaN None
2 NaN CLOSED
3 NaN CONTINUOUS_TRADING
4 NaN None
5 NaN UNSCHEDULED_AUCTION
6 NaN UNSCHEDULED_AUCTION
7 F OPENING_AUCTION
8 NaN CONTINUOUS_TRADING
9 SL CLOSING_AUCTION
10 NaN HALTED
11 NaN None
12 NaN None
13 L CLOSED
</code></pre>

<p>I'm trying to get the record count from multiple tables, like this.</p>
<pre><code>Select count(*)
From
(
Select Hist.Common_Name,
Veg.ID,
EDSH.ID
From Hist_Event_View as Hist
Inner Join Vegtables as Veg
ON Hist.Common_Name = Veg.ID
INNER JOIN Final as Final
ON Hist.Common_Name = Final.ID) as Sub
</code></pre>
<p>The problem is that ID is being used multiple times, so SQL Server can't resolve which ID is coming from which table in the outer query, I think. How can I handle this issue? Thanks.</p>

<p>I have a <code>TabPane</code> declared like this :</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.TabPane?>
<TabPane fx:id="rootNode" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" stylesheets="@dark_theme.css" tabClosingPolicy="UNAVAILABLE" xmlns="http://javafx.com/javafx/19" xmlns:fx="http://javafx.com/fxml/1" fx:controller="controllers.AppController" />
</code></pre>
<p>And I want to add tabs from my controller. So I do :</p>
<pre><code> jsonConfig.getAvailableChannelIds().forEach( chId -> {
try {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("tab_item.fxml"));
Tab item = fxmlLoader.load();
item.setText(String.format("%d", chId));
rootNode.getTabs().add(item);
}catch (Exception e) {
e.printStackTrace();
}
});
</code></pre>
<p>"tab_item.fxml" looks as follows :</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Tab?>
<?import javafx.scene.layout.VBox?>
<Tab xmlns:fx="http://www.w3.org/1999/XSL/Transform">
<VBox>
<fx:include source="test.fxml"/>
</VBox>
</Tab>
</code></pre>
<p>And finally "test.fxml" :</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" style="-fx-background-color: red;" xmlns="http://javafx.com/javafx/19" xmlns:fx="http://javafx.com/fxml/1" />
</code></pre>
<p>And here is what I have :</p>
<p><a href="https://i.stack.imgur.com/H3dZe.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/H3dZe.jpg" alt="enter image description here" /></a></p>
<p>What am I missing to fill the <code>Tab</code> content with the red square ?</p>

<p><strong>Problem</strong>:</p>
<p>I want to calculate at several times the adjacency matrix <code>A_ij</code> given the adjacency list <code>E_ij</code>, where <code>E_ij[t,i] = j</code> gives the edge from <code>i</code> to <code>j</code> at time <code>t</code>.</p>
<p>I can do it with the following code:</p>
<pre class="lang-py prettyprint-override"><code>import numpy as np
nTimes = 100
nParticles = 10
A_ij = np.full((nTimes, nParticles, nParticles), False)
E_ij = np.random.randint(0, 9, (100, 10))
for t in range(nTimes):
for i in range(nParticles):
A_ij[t, i, E_ij[t,i]] = True
</code></pre>
<p><strong>Question:</strong></p>
<p>How can I do it in a vectorized way, either with fancy indexing or using numpy functions such as <code>np.take_along_axis</code>?</p>
<hr />
<p><strong>What I tried:</strong></p>
<p>I expected this to work:</p>
<pre class="lang-py prettyprint-override"><code>A_ij[:,np.arange(nParticles)[None,:,None], E_ij[:,None,np.arange(nParticles)]] = True
</code></pre>
<p>But it does not.</p>
<hr />
