74,247,945 | <p>I'm new to Python for the last 3 months but have quite a bit of development
experience. I'm trying to figure out a good way to manage a collection of
functions and classes that are shared across several projects. I'm working on
a Windows 10 machine that I don't have admin access to, so the PATH variable is not an option. I'm using VS Code with Python 3.10</p>
<p>I have several active projects and my current working directory structure is:</p>
<p>python</p>
<ul>
<li>Project A</li>
<li>Project B</li>
<li>Project C</li>
<li>Common</li>
</ul>
<ul>
<li>
<pre><code> __init__.py (empty)
</code></pre>
</li>
<li>
<pre><code> ClassA.py
</code></pre>
</li>
<li>
<pre><code> ClassB.py
</code></pre>
</li>
<li>
<pre><code> functions.py
</code></pre>
</li>
</ul>
<p>I've added a .pth file in AppData/Local/Programs/Python/Python310/Lib/site-packages
which contains the path to the python root folder.</p>
<p>Right now I'm able to use this configuration by importing each file as a separate module:</p>
<pre><code>from Common.ClassA import ClassA
from Common.ClassB import ClassB
from Common import functions as fn
</code></pre>
<p>I would like to do something like:</p>
<pre><code>from Common import ClassA, ClassB, functions as fn
</code></pre>
<p>Just looking for some experienced advice on how to manage this situation. Thanks to any and
all who have time to respond.</p>

74,247,954 | <p>I study streams and solve various tasks with them. And I can’t cope with one, I have a map with cities and the amount of violence. I need to display only the name of the cities in descending order of the number of population.In fact, it should display the cities in this order Brest, Vitebsk,Minsk, Mogilev. No matter how I write, I can't, here's my code.</p>
<pre><code> Map<String,Integer> cities = new HashMap<>();
cities.put("Minsk",1999234);
cities.put("Mogilev",1599234);
cities.put("Vitebsk",3999231);
cities.put("Brest",4999234);
List<Integer> collect =cities.entrySet().stream()
.map(o->o.getValue())
.sorted(Comparator.reverseOrder())
.collect(Collectors.toList());
</code></pre>
<p>So far, I was able to sort by population, but I don’t understand how to display the name of the cities sorted further</p>

74,247,969 | <p>I'm learning javascript through MDN documentation. They have an example on the <a href="https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Building_blocks/Functions" rel="nofollow noreferrer">function topic</a> which apparently I'm unable to understand.</p>
<pre><code>const textBox = document.querySelector("#textBox");
const output = document.querySelector("#output");
textBox.addEventListener('keydown', (event) => output.textContent = `You pressed "${event.key}".`);
</code></pre>
<p>I've read a few documentation on<strong>key down</strong> function and I assume it is supposed to return some value for every character entered (correct me if I'm wrong); but in the example on MDN, it only returns <strong>enter</strong> when I press enter key and <strong>backspace</strong> when I press backspace (while input box has no other characters). I'm reading this example on a mobile device btw.</p>

74,248,004 | <p>I'm working on document clustering where I first build a distance matrix from the tf-idf results. I use the below code to get my tf-idf matrix:</p>
<pre><code>from sklearn.feature_extraction.text import TfidfVectorizer
vectorizer = TfidfVectorizer(stop_words={'english'})
X = vectorizer.fit_transform(models)
</code></pre>
<p>This results in a matrix of (9069, 22210). Now I want to build a distance matrix from this (9069*9069). I'm using the following code for that:</p>
<pre><code>import numpy as np
import pandas as pd
from scipy.spatial import distance_matrix
from scipy.spatial import distance
arrX = X.toarray()
rowSize = X.shape[0]
distMatrix = np.zeros(shape=(rowSize, rowSize))
#build distance matrix
for i, x in enumerate(arrX):
for j, y in enumerate(arrX):
distMatrix[i][j] = distance.braycurtis(x, y)
np.savetxt("dist.csv", distMatrix, delimiter=",")
</code></pre>
<p>The problem with this code is that it's extremely slow for this matrix size. Is there a faster way of doing this?</p>

</code></pre>
<p>this above while loop runs 60 times in 1 second after we set the frame rate limit, I want to know how does SFML internally manage to run the while loop in a controlled manner(i.e maintaining frame rate) by just using the "window.isOpen()" function in while loop condition. Or is there anything else working under the hood.</p>
<p>I am unable to understand how does setFramerateLimit works in SFML.</p>

<p>im using ngif on the spinner to clear it from the dom and show data once it fetched sucessfuly the problem is that i must open the componet then go to another component then come back to it again to show the data otherwise the data wont show... thanks in advance</p>

<p>Basically I'm trying to check if that method property exist in another object. I just want to tell the proxy to get the value from another object without passing it into the constructor.</p>

74,248,156 | <p>I have a fairly straightforward database schema. I have a list of Cemeteries, each Cemetery may have a CountryId for where it's located. The majority are currently null. I am attempting to return a paged result.</p>
<p>If I do the below, it works perfectly fine, fast and paged. If I use the <code>.Include</code>, I can see the <code>List<T></code> returned to the controller, and the controllers return sit to the API. The API however shows error 500.</p>
<pre><code>public Shared.Models.Paging.PagedResult<Cemetery> List(int page, string filter)
{
const int pageSize = 10;
var data = _ctx.Cemeteries
// .Include(p => p.Country)
.AsNoTracking()
.AsQueryable();
if (!string.IsNullOrEmpty(filter) && filter != "null")
{
data = data.Where(filter);
}
return data.GetPaged(page, pageSize);
}
public partial class Cemetery
{
public int Id { get; set; }
public string Name { get; set; } = null!;
public int? CountryId { get; set; }
public DateTime? CreatedAt { get; set; }
public DateTime? UpdatedAt { get; set; }
public virtual Country? Country { get; set; }
}
public partial class Country

public Country()
{
Cemeteries = new HashSet<Cemetery>();

public string Name { get; set; } = null!;
public DateTime? CreatedAt { get; set; }
public DateTime? UpdatedAt { get; set; }
public virtual ICollection<Cemetery> Cemeteries { get; set; }
}
</code></pre>
<p>If I place a <code>try/catch</code> in the code, all I get is an error 500, the server did not indicate success.</p>
<pre><code>public async Task<PagedResult<CemeteryModel>> List(int page, string filter)
{
var searchParams = $"/{page}?filter=";
searchParams += string.IsNullOrEmpty(filter) ? "null" : filter;
return await _httpClient.GetFromJsonAsync<PagedResult<CemeteryModel>>($"api/Cemetery/List{searchParams}");

74,248,207 | <p>I am trying to read several TXT files, I make some modifications to them and then I convert them into a DataFrame with Pandas and there I also run some modification processes, so far everything is fine, everything works perfect, I do it through a for loop but at the moment of save the xlsx file and create the first sheet and it doesn't create new sheets, it just creates the first one.</p>
<p>the code is the following:</p>
<pre><code>from netmiko import ConnectHandler
from datetime import datetime
import re
from pathlib import Path
import os
import pandas as pd
ruta = Path("E:\Python\Visual Studio Code Proyects\M2M Real\Archivos")
def is_free(valor):
color = 'green' if valor == "free" else 'white'
return 'background-color: %s' % color
list_txt = [ruta/"Router_a.txt", ruta/"Router_b.txt"]
for txt in list_txt:
host = txt.stem
sheet_name=f'{host}-Gi0-3-4-2'
ruta_host = f'{ruta}\\interfaces.xlsx'
df = pd.read_fwf(txt)
df["Description"] = (df.iloc[:, 3:].fillna("").astype(str).apply(" ".join, axis=1).str.strip())
df = df.iloc[:, :4]
df = df.drop(columns = ["Status", "Protocol"])
df.Interface = df.Interface.str.extract('Gi0/3/4/2\.(\d+)')
df = df[df.Interface.notnull()].reset_index()
df = df.drop(columns = ["index"])
df['Interface'] = df['Interface'].astype(int)
df = df.set_index('Interface').reindex(range(1,50)).fillna('free').reset_index()
df = df.style.applymap(is_free)
with pd.ExcelWriter(ruta_host, mode='a') as writer:
df.to_excel(writer, sheet_name, index=False)
</code></pre>
<p>the format of the txt is as follows, it is worth clarifying that basically both txt from both routers are almost identical:</p>
<pre><code>Interface Status Protocol Description
Gi0/3/4/2 up up ENLACE A Router_X
Gi0/3/4/2.5 up up Frontera Cliente A
Gi0/3/4/2.6 up up Frontera Cliente B
Gi0/3/4/2.7 up up Frontera Cliente C
Gi0/3/4/2.8 up up Frontera Cliente D
Gi0/3/4/2.9 up up Frontera Cliente E
</code></pre>
<p>Any idea what I'm doing wrong?</p>

74,248,286 | <p>I have a something that is sending an SNMP set command to my server. I can see the packet in wireshark, and I know that I'm getting the packet. Once I get this packet I need to decode it and do an operation (using a script). I can't believe I am the first person that needs to do this, but have googled for hours and found no one else in this use case. I've seen utilities that allow me to use a get snmp, but as the set doesn't actually set anything on my server, there is no way to get it. It doesn't seem traps are helpful as that seems to find the message, as its not labeled a trap. Is there a way to convert the set to a trap once my server gets it, or is there a better method. My server is windows, but if I have to create a linux VM to make this easier I'm all ears. As of now I'm thinking powershell, but if there is an easy way in go, c#, etc I would totally do it.</p>
<p>I am attempting to get a SNMP SET to and use that as a trigger for running a script.</p>

<p>Lets say I have a header file, myHeader.h and main.c which would like to include myHeader.h. Assume they are in the same directory.</p>
<p>In main.c, I could write #include "myHeader.h". However, according to my professor the "" is permitted because gcc will check in the current directory for anything in the "". However, where I am lost is when it comes to how I could add myHeader.h to the gcc header file search path such that #include <myHeader.h> would work. I am wondering what gcc commands would work, and why they work in specific. I would love any references(that aren't super nerdy) to better understand this.</p>
<p>So far, I researched on stackoverflow and on google, and it said something about -Idir gcc command, where dir is the directory you would like to add to the header file search path, but I am confused as to why this works or how to actually implement it. Since the "path" to myHeader.h is CStuff/workspace/myHeader.h I attempted to do gcc -I/CStuff/workspace/myHeader.h but this didn't really work out. I really thought it would take that directory and add it to the header file search path, but it just gave me an error.</p>
<p>I am a very confused business major so please take it easy on me! I really would love a dumbed-down explanation or a reference to a source that is more "basic" and has more than 1-2 sentences of explanation(if possible).</p>

74,248,409 | <p>New to VBA. I have a large PPT with over 150 slides, and I have run a VBA macro to tag them (SlidesA ... SlidesF) into tag "groupings". I have a userform with a bunch of check boxes to select slide groupings the user wants keep. After selecting the groupings the user wants to keep they click an OK button. I have some code (below) to find slides that are not checked and delete them based on Tags.Value, and keep the rest. But for some reason it's not deleting all the slides, it's just deleting like 4 of them in SlidesA group.</p>
<pre><code>Private Sub btnOK_Click()
' Slide.Tag has .Name and .Value parameters
If chkSlidesA = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesA" Then
s.Delete
End If
Next i
End With
Next
Else
If chkSlidesB = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesB" Then
s.Delete
End If
Next i
End With
Next
Else
If chkSlidesC = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesC" Then
s.Delete
End If
Next i
End With
Next
Else
If chkSlidesD = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesD" Then
s.Delete
End If
Next i
End With
Next
Else
If chkSlidesE = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesE" Then
s.Delete
End If
Next i
End With
Next
Else
If chkSlidesF = False Then
For Each s In Application.ActivePresentation.Slides
With s.Tags
For i = 1 To .Count
If .Value(i) = "SlidesF" Then
s.Delete
End If
Next i
End With
Next
Else
End If
End If
End If
End If
End If
End If
Unload Me
End Sub
</code></pre>
<p>I have verified the slides are tagged with the right values by running some VBA to read the tags and display a MsgBox to display the tag value.</p>
<p>I'm trying to understand why it isn't deleting all the slides.</p>

74,248,440 | <p>Probably this is a very stupid mistake but I can't find a solution. I have the lists below:</p>
<pre><code>node_pair = [('a', 'b'), ('b', 'a')]
edge_list = [
(1, 'unuseful thing', {'orig-id': 'a'}),
(11, 'unuseful thing', {'orig-id': 'b'}),
]
</code></pre>
<p>I need to find the numeric couple in <code>edge_list</code> that is related to <code>node_pair</code>. For <code>('a', 'b')</code> I will see <code>(1, 11)</code> and for <code>('b', 'a')</code> I will see <code>(11, 1)</code>. Below my code:</p>
<pre><code>for pair in node_pair:
start_node = pair[0][0]
end_node = pair[1][0]
print(f'from {start_node} --> to {end_node}')
graph_start_end_node = []
for edge in edge_list:
edge_orig_id = edge[2]['orig-id']
if start_node == edge_orig_id:
edge_start_node = edge[0]
graph_start_end_node.append(edge_start_node)
if end_node == edge_orig_id:
edge_start_node = edge[0]
graph_start_end_node.append(edge_start_node)
print(graph_start_end_node)
</code></pre>
<p>The result is:</p>
<pre><code>from a --> to b
[1, 11]
from b --> to a
[1, 11]
</code></pre>

<p>Does anyone know how to create a grid like this using GridView.builder. Any other alternative will be much appreciated too.</p>
<p>The text in the container should be dynamic as well based on the size of the text.</p>
<p>Thank you</p>
<p>Tried using gridView but the container was always of fixed width and height. The row items was not dynamic as well</p>

74,248,480 | <p>Imagine we have a table like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>type</th>
<th>created_at</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>James</td>
<td>male</td>
<td>2022-03-02</td>
</tr>
<tr>
<td>2</td>
<td>Jane</td>
<td>female</td>
<td>2022-04-02</td>
</tr>
<tr>
<td>3</td>
<td>Kirk</td>
<td>male</td>
<td>2022-03-04</td>
</tr>
<tr>
<td>4</td>
<td>Sarah</td>
<td>female</td>
<td>2022-04-04</td>
</tr>
<tr>
<td>5</td>
<td>Jason</td>
<td>male</td>
<td>2022-03-05</td>
</tr>
</tbody>
</table>
</div>
<p>And i want to <em>group by</em> type and just get latest records based on <code>created_at</code>.<br />
So i tried this code and not bad:</p>
<pre><code>result = User.objects.values('type').annotate(
latest_date=Max('created_at'),
)
</code></pre>
<p>When print the <strong>result</strong> i face to this:</p>
<pre><code><QuerySet [
{'type': 'male', 'latest_date': '2022-03-05'},
{'type': 'female', 'latest_date': '2022-04-04'}
]>
</code></pre>
<p>My question is: Where is other fields <code>id</code> and <code>name</code>?
I expect to get:</p>
<pre><code><QuerySet [
{id: 5, name: 'Jason', 'type': 'male', 'latest_date': '2022-03-05'},
{id: 4, name: 'Sarah', 'type': 'female', 'latest_date': '2022-04-04'}
]>

74,248,540 | <p>I am trying to make an array store each number I type in.</p>
<p>Some like:
<strong>Enter number:687544</strong></p>
<p>And return as an array like:
<strong>6 8 7 5 4 4</strong></p>
<p>I only figure out how to store the nums in order in the "store (num) " function below:</p>
<pre><code>#include<stdio.h>
int store(int num);
int main()
{
int num;
printf("Enter number: ");
scanf("%d",&num);
return store(num);
}
int store(int num)
{
if(num!= 0)
{
int mod = num % 10; //split last digit from number
store(num/10); //recuring it back to the right order
printf("%i\n",mod); //divide num by 10. num /= 10 also a valid one
}
}
</code></pre>
<p>Following is I tried but not working code</p>
<pre><code>#include<stdio.h>
int store(int num);
int main()
{
int num,d;
printf("Enter number: ");
scanf("%d",&num);
for(d=0; num<0;d++);
{
num /= 10;
}
int a[d];
int i;
for(i=0;i<d;i++){
a[d]=store(num);
}
printf("%d \n",a[d]);
}
int store(int num)
{
if(num!= 0)
{
int mod = num % 10;
store(num/10);
return mod;
}
}
</code></pre>
<p>Unexpected Result.......</p>
<pre><code>Enter number: 123
115183680
</code></pre>
<p>Feel like I almost there but I have no idea which part goes wrong. May I ask how to fix this?</p>
<p>I only figure out how to store the nums in order in the "store (num) " function, however I tried the to expand my code that the result is not I expected.</p>

74,248,547 | <p>I am taking the Operating Systems course and trying to understand how exactly <code>fork()</code> works. I know the basic definition: "fork() creates a new process by duplicating the calling process.".</p>
<p>I was told the child process will only execute the codes below the <code>fork()</code> statement. What I don't understand is, let's say we have a 10-lined code. If line 6 is <code>fork()</code>, Will the whole code from lines 1 to 10 run in the child process or only 6 to 10 ?</p>
<p>How will this code will work:</p>
<pre><code>int main(){
pid_t smith;
int a=2; int b=3;
smith = fork();
if(smith == 0){
fork();
a++;
fork();
}
else if(smith > 0){
b++;
fork();
}
printf("%d %d",a,b);
}
</code></pre>
<p>The <code>fork()</code>s in if blocks are confusing. How will they act? When a child process is created from the fork() in the else if, what code will it run?</p>

74,248,585 | <p>Given a Mongo collection of data of the form:</p>
<pre><code>// 'Entities'
{ tags: [{ a: '1', b: '1' }, { a: '2', b: '3' }] }
{ tags: [{ a: '1', b: '2' }, { a: '2', b: '3' }] }
{ tags: [{ a: '4', b: '4' }, { a: '4', b: '5' }, { a: '6', b: '7' }] }
</code></pre>
<p>I'd like to find all documents whose 'tag' entry has any of the following objects:</p>
<pre><code>[{ a: '1', b: '1' }, { a: '4', b: '4' }]
</code></pre>
<p>With the example data, this would match the first and third elements:</p>
<pre><code>{ tags: [{ a: '1', b: '1' }, { a: '2', b: '3' }] }
{ tags: [{ a: '4', b: '4' }, { a: '4', b: '5' }, { a: '6', b: '7' }] }
</code></pre>
<p>At the moment I'm doing it with a generated query (JS):</p>
<pre><code>entities.find({
$or: tags.map(tag => ({
tags: { $elemMatch: tag },
})
})
</code></pre>
<p>But this seems very inefficient, as if the number of tags I'm searching for is large I'll be essentially running hundreds of separate queries. Is there a better way?</p>

74,248,598 | <p>I'm trying to create a plug-in system using Symfony and its bundle system. I know bundle must be independent but for my system, I know my bundle will never be used in another context.</p>
<p>I have a doctrine entity called "Mark" and I want to associate an entity from the main application called "Student" so a student can have a mark from my mark plugin.</p>
<p>For the moment, I only have an entity Mark that is really simple and I don't know how to associate a new field to my Student entity</p>
<pre class="lang-php prettyprint-override"><code>namespace Zenith\QuinzeBundle\Model;
[...]
#[ORM\Entity(repositoryClass: MarkRepository::class)]
class Mark
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
private ?string $comment = null;
public function getId(): ?int
{
return $this->id;
}
public function getComment(): ?string
{
return $this->comment;
}
public function setComment(string $comment): self
{
$this->comment = $comment;
return $this;
}
}
</code></pre>
<p>And this is my Student entity (simplified) :</p>
<pre class="lang-php prettyprint-override"><code>namespace Zenith\Entity;
[...]
#[ORM\Entity(repositoryClass: StudentRepository::class)]
class Student
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
private ?string $firstname = null;
#[ORM\Column(length: 255)]
private ?string $name = null;
public function __construct()
{
$this->userfieldValues = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getFirstname(): ?string
{
return $this->firstname;
}
public function setFirstname(string $firstname): self

$this->firstname = $firstname;

public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;

</code></pre>
<p>How can I associate this two entities that one is in an app and the other in a bundle ?</p>

74,248,609 | <p>I have two div connected to each other through svg line(implementation from d3js chart). On certain action, I want to fade/greyout some of the divs. I am able to achieve it by setting opacity 0.5. But it makes the div transparent so background svg line gets visible. I have created a jsfiddle to demo the issue.</p>
<pre><code><div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#777; position:absolute;">
<div class="child1">
text

</div>
<div id="div2" style="width: 100px; height: 100px; top:200px; left:200px; background:#333; position:absolute;">
<div class="child1">
text
</div>
<div class="child2">
</div>
</div>
<svg width="300" height="250"><line x1="50" y1="50" x2="350" y2="350" stroke="black"/></svg>
<button onclick="fade()">
fade
</button>
<button onclick="reset()">
reset
</button>
function fade () {
document.getElementById('div1').className = 'greyout';
}
.greyout {
opacity: 0.5;
}
</code></pre>
<p><a href="https://jsfiddle.net/srxoL1zj/2/" rel="nofollow noreferrer">jsfiddle link</a></p>
<p>Is there any way to hide line inside div when opacity is set to 0.5?</p>

However, whenever I do the <code>translateY</code>, my buttons move to the side instead. Here is the HTML and CSS; button-2 is the problematic one:</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>.container {

text-align: center;
text-decoration: none;
outline: none;
color: #fff;
background-color: #4CAF50;
border: ridge;
border-radius: 15px;

transform: translateY(10px);
}
#button-2 {

top: 62%;
left: 50%;
/* if i remove this line, translation works as expected
but then the button is no longer centered horizontally
consequently, keeping the line breaks the affect
but the button can be centered horizontally
*/
transform: translate(-50%, 0);
}
#button-2:hover {
background-color: cornsilk;
}
#button-2:active {
background-color: cornsilk;

transform: translateY(5px);
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><h2>Animated Button - "Pressed Effect"</h2>
<div class=container>
<button id="button-1">Btn1</button>
<button id="button-2">Btn2</button>
</div></code></pre>
</div>
</div>
</p>
<p>The problem seems to stem from <code>transform: translate(-50%, 0);</code>, which is what I have to do to center button-2 horizontally in the <code>container</code> div. I can remove that line and the effect works, but then button-2 is no longer centered horizontally. Why is it that <code>transform: translate(-50%, 0);</code> seemingly causes the subsequent <code>transform: translateY(5px);</code> not to work for button-2? Is there anyway I can horizontally (but not vertically) center button-2 while also being able to achieve the desired effect?</p>

<li>5 second delay between "Hello" and the first "Morning".</li>

<p>My problem is that on loading the web-page, the output is:</p>
<pre><code>Hello
Morning
Evening
Morning
Morning
Morning

<p>How can I make sure that the function is ran in the order I want it to and not this mixed output? The first 3 outputs also appear instantly instead of a delay. How do I avoid that?</p>

74,248,847 | <p>I cannot understand this about C. Since every variable and function has to be unique (since they are global) then how can this be possible with a huge library like the standard C library and 3rd party libraries? Yes you could make every variable "static" but that does not seem to be the case.</p>
<p>For example I was looking and I found this <code>random_data</code> struct <code>stdlib.h</code> and I am wondering - what are the chances that another library also has a struct called <code>random_data</code>? Won't that be a clash?</p>
<p><strong>stdlib.h</strong></p>
<pre><code>struct random_data {
int32_t *fptr;
int32_t *rptr;
...
};
</code></pre>
<p>I mean what if both <code>stdlib</code> and <code>stdio</code> have a struct called <code>random_data</code> and I was to include both libraries in my program? The standard library has thousands of functions and variables and it seems impossible that they all would be unique. Also what about 3rd party libraries? What if a 3rd party library also has a struct called <code>random_data</code>?</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int main() {
}

<p>I'm trying to start my game with none of the systems in place and the only thing on the screen is some background objects and the BUTTON.</p>
<p>when I press the button, I want to instantiate all the objects that I need in the game.(which i know how to do, and isnt my problem.)</p>
<p>MY PROBLEM is that i want the button to either</p>
<ol>
<li>destroy itself or 2) Move off screen or 3) scale down so it cant be seen.</li>
</ol>
<p>the script i have in place should be doing the scale down solution as thats attached to the onpress function
but nothing seems to happen to the button on press but it does seem to manipulate the prefab of the button that isnt even on screen?</p>
<p>CAN A BUTTON NOT MANIPULATE ITSELF?</p>

<p>It is not counting by period in my real work file. I don't know why. Probably something to do with date formats? Now when I made this dummy file, I just changed names, and now it is working. The names in the real file are of people instead of fruits, like: "Doe, John", "Jane, Mary" etc. Could this be the problem and not the date format?</p>
<p>Also, I would like to have only 2 columns: one with the names of the unique items, and the 2nd with count "By Period". If I want the total count, I will just choose from the validation menu. The name's column on the left should be sorted by descending order according to the count by period.</p>
<p>Here is a file:<br/>

<p><strong>EDIT:<BR/></strong>
The expected result is below. The count would change according to the period chosen above. In this case by month:<br/></p>

74,248,882 | <p>I'm writing a program to play Chess. My <code>Game</code> class has the async function <code>play</code>. This function returns when the game ends, returning a Winner enum, which is either a stalemate or a win for some colour.</p>
<p>In my <code>main</code> fn, I want to run <code>game.play</code>, then run <code>game.render()</code> repeatedly, until <code>game.play</code> returns a Winner, at which point the loop should stop.</p>
<p>Having attempted to read the docs, I don't really understand why Pinning or Boxing is neccesary in order to poll the future, and I haven't been able to get it working.</p>
<p>The desired code for <code>main</code> should look something like this:</p>
<pre><code> let textures = piece::Piece::load_all_textures().await;
let mut game = game::Game::new(player::Player::User, player::Player::User);
let future = game.play();
while None = future.poll() {
game.render(textures).await;
next_frame().await;
}
// Do something now that the game has ended
</code></pre>
<p>I also understand that I will run into issues with borrow checking with this code, but that's a problem for me to deal with once I figure this one out.</p>
<p>What is the easiest way of attempting what I am trying to do?</p>

74,248,895 | <p>I have next big JSON...</p>
<pre><code>{
"field1": "value1",
"field2": "value2",
...
"field100": "value100",
}
</code></pre>
<p>...and appropriate POJO</p>
<pre><code>@Builder
@Data
public class BigJsonDto{
private String field1;
private String field2;
private String field100;
}
</code></pre>
<p>Let's say all fields are required and nullable except <code>field1</code> that can't have a <code>null</code> value.</p>
<p>So I want to tell Jackson (or another way) stop serialization if one or more required fields have <code>null</code> value, rather than just ignore it (with <code>@JsonInclude</code>). How can I reach it?</p>
<p>It would be nice if it's possible to use built-in <code>ObjectMapper</code>.</p>
<p>I tried to use <code>@JsonProperty(required = true)</code> annotation but as I can see this annotation is used in deserialization. So in this case, I got required fields with null values.</p>

74,248,898 | <p>I am trying to create a regular expression that will capture JavaScript object properties, but I only want top level properties.<br />
So for example I want to capture <code>this.nodeName</code> but I do not want to capture <code>this.nodeName.length</code></p>
<p>I am trying the following expression: <code>(this\.\w+)(?!\.)</code><br />
But the lookahead seems to be only working on the <code>\w+</code> and not on the whole capture group and I don't understand why this is.<br />
For example if I apply <code>this(?!\.)</code> to <code>this.</code> then it doesn't match <code>thi</code>, so I don't understand why capture groups seem to act differently.</p>
<p><a href="https://regexr.com/717lh" rel="nofollow noreferrer">Here is a demo of my expression</a></p>
<p>Perhaps someone more experienced in regular expression could help me out.</p>
<p>Thanks</p>

74,248,917 | <p>I've made a dummy project just to show what is trying to be made. I'm going for a transition on color for text without CSS (as I just can't wrap my head around CSS). In the dummy project, the text starts from red</p>
<p><a href="https://i.stack.imgur.com/qKma0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qKma0.png" alt="enter image description here" /></a></p>
<p>then goes to blue</p>
<p><a href="https://i.stack.imgur.com/Ib6Vg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ib6Vg.png" alt="enter image description here" /></a></p>
<p>Found out about <code>FillTransition</code> though that only works with shapes, so this would be a similar function. My other attempt was trying to get the RGB values of both colors then stick them in a <code>do while</code> with a new <code>Color</code> just to test it out though the transition is almost instant as the application starts so it changes the color but without transitioning effect. I'm thinking of making an <code>Timeline</code> for this similar to the <code>do while</code> but I haven't tried that yet.</p>
<p>Before going into this what are some ways to make this effect?</p>
<p>Here's the dummy code:</p>
<pre><code>package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
BorderPane root = new BorderPane();
Scene scene = new Scene(root,400,400);
StackPane stack = new StackPane();
Text text = new Text("Hello there StackOverflow, how are you? (:");
Color color1 = Color.RED;
Color color2 = Color.BLUE;
double r1 = color1.getRed();
double g1 = color1.getGreen();
double b1 = color1.getBlue();
double r2 = color2.getRed();
double g2 = color2.getGreen();
double b2 = color2.getBlue();
Color colorEffect = new Color(r1, g1, b1, 1.0);
stack.setLayoutX(200);
stack.setLayoutY(200);
text.setFont(Font.font(16));
text.setFill(colorEffect);
stack.getChildren().add(text);
root.getChildren().add(stack);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}

74,248,986 | <p>I am running the following query:
(see <a href="https://learn.microsoft.com/en-us/sql/relational-databases/search/query-with-full-text-search?view=sql-server-ver16" rel="nofollow noreferrer">https://learn.microsoft.com/en-us/sql/relational-databases/search/query-with-full-text-search?view=sql-server-ver16</a>)</p>
<pre><code>SELECT KEY_TBL.RANK, FT_TBL.*
FROM dbo.Forums AS FT_TBL
INNER JOIN FREETEXTTABLE(dbo.Forums, Title,'{searchTerm}') AS KEY_TBL
ON FT_TBL.Id = KEY_TBL.[KEY]
ORDER BY KEY_TBL.RANK DESC
</code></pre>
<p>This works great when I run it in SQL Server Management Studio, but when I run it in my API, I do not get the rank. It is always 0.</p>
<p>Here is my model:</p>
<pre><code>public class Forum : BaseModel
{
public ApplicationUser? ForumAuthor { get; set; }
public string ForumAuthorId { get; set; } = "";
[Required (AllowEmptyStrings = false,ErrorMessage = "A Title is required")]
public string? Title { get; set; }
public List<Post>? Posts { get; set; }
[NotMapped]
public int RANK { get; set; }
}
</code></pre>
<p>Notice that RANK has a <code>[NotMapped]</code> attribute. I did that because I don't have a RANK field on the Forums table.</p>
<p>So I decided to create a <code>ForumViewModel</code> that has a RANK field without the <code>[NotMapped]</code> attribute.</p>
<p>Here is my query:</p>
<pre><code>List<ForumViewModel> forums = await _context.Forums.FromSqlRaw(forumSql).Select(x => new ForumViewModel()
{
ForumAuthor = x.ForumAuthor,
ForumAuthorId = x.ForumAuthorId,
Posts = x.Posts,
RANK = x.RANK,
Title = x.Title,
}).ToListAsync();
</code></pre>
<p>The result is the same. RANK = 0.</p>
<p>If I remove the <code>[NotMapped]</code> attribute, I get the rank with a valid number greater than 0. So I believe the <code>[NotMapped]</code> attribute is the problem.</p>
<p>The rank is returned by the FREETEXTTABLE. So, I am using DbContext to query my Forums table, joined to FREETEXTTABLE. This table returns the rank of the search term against all text in the title field of the Forums table. Please see the link I put in the beginning of this post.</p>
<p>How can I get the Rank without having to needlessly add the <code>Rank</code> field to my <code>Forum</code> table.</p>
<p>Edit: Solved
I figured it out. There is a data annotation for this situation:</p>
<pre><code>[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public int RANK { get; set; }
</code></pre>

74,249,054 | <p>I just upgraded to cordova-android@11.0.0 targeting API 31. This required replacing the splash screen plugin from my previous builds. I use <code>AutoHideSplashScreen = false</code> so that I can hide the splash screen after the UI is rendered. This works fine on iOS but the splash screen persists forever on Android despite calls to <code>navigator.splashscreen.hide()</code> (even with the debugger). This happened both on API 31 and older devices. I resorted to auto-hide with a long fade for now, to get something working. I tried several different config.xml variants so I'm not sure whether putting one here will be useful, but for all of them <code>AutoHideSplashScreen = false</code> on Android did not work.</p>

74,249,075 | <p>I have a single dynamodb table. One of the type records is called "Result" and one of its PK stores a composite key (class, student and exercise). This is the example design:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>PK</th>
<th>SK</th>
<th>SCORE</th>
<th>...</th>
<th>GSI PK 1</th>
<th>GSI SK 1</th>
</tr>
</thead>
<tbody>
<tr>
<td>RESULT#001</td>
<td>RESULT#001</td>
<td>90</td>
<td>...</td>
<td>CLASS#MATH#STUDENT#TOM#EXERCISE#1</td>
<td>RESULT#001</td>
</tr>
</tbody>
</table>
</div>
<p>Use cases:</p>
<ol>
<li>Find result by student (<code>gsi pk 1 = "CLASS#MATH#STUDENT#TOM#EXERCISE#1", gsi sk 1 = begins_with("RESULT")</code>)</li>
</ol>
<p>Now, there's a new use case:
2. Find all results by student</p>
<p>To meet this requirement, I could either:</p>
<ul>
<li>Add a new GSI which does not store the exercise ID. The query will look: (<code>gsi pk 2 = "CLASS#MATH#STUDENT#TOM", gsi sk 2 = begins_with("RESULT")</code>)</li>
<li>In the backend service, iterate over all exercises and execute multiple dynamo db queries re-using GSI 1</li>
</ul>
<p>First option may be performant. However, it requires to update the dynamo db table whereas second option uses same design. What's a recommended design criteria to follow?</p>

74,249,226 | <p>I am trying to write a program that will convert a Stream<String> into a String<Record> where everytime there is a comma in the string, it puts that data into one section of the data. My first thought on doing this was to use split() like so:</p>
<pre><code>return fileToStream("data.csv").forEach(s -> s.split(","));
</code></pre>
<p>The fileToStream function is simply taking the data.csv and converting it into a Stream
I don't quite understand why this is returning void, any help would be greatly appreciated.</p>
<p>I expected it to take something like 123,hello,hello,hello,123,123 and instead of it all being one string, turning it into a record of int, string, string, string, double, double, etc.</p>

74,249,262 | <p>I am trying to write a code that will work like this:</p>
<p>First function of the code is registration:
here the user will input their username and password, then the code will create a text file named after the username and it will include 2 lines:</p>
<pre class="lang-none prettyprint-override"><code>1.username
2.password
</code></pre>
<pre><code>import time
def registracia():
print ("To register you'll need to type your username and your password.")
time.sleep (1.5)
userName = input("username: ")
time.sleep (1.5)
passWord = input("password: ")
filename = userName + ".txt"
file = open(filename, "+w")
file.write (userName+"\n")
file.write (passWord)
file.close
if __name__ == "__main__":
registracia()
</code></pre>
<p>Then there's the 2nd function of the code and that will be login.
My thought for the login is that it will ask for input of the username, then it will open the file named after the username and read the 2nd line, after reading the line it will ask for input of password and then use if to check if the input is equal to the 2nd line.</p>
<p>My problem is that the readline only reads 1 letter from the username, at least that's what I think it's doing.</p>
<pre><code>import time
print ("To login you'll need to type your username first")
def login():
#time.sleep (1.5)
userName = input ("username: ")
filename = userName +".txt"
file = open(filename, "r")
#time.sleep (1.5)
realPassWord = file.readline(2)
print (realPassWord)
passWord = input ("password: ")
if passWord == realPassWord:
print ("successfuly logged in ")
elif passWord != realPassWord:
print ("incorrect password")
login()
login()
</code></pre>
<p>I'm also adding an example of input and outputs to see what's happening:</p>
<p>Registration:</p>
<p>Input:</p>
<pre class="lang-none prettyprint-override"><code>username: abc321
password: cba123
</code></pre>
<p>Output:</p>
<p>abc321.txt (a text file):</p>
<pre class="lang-none prettyprint-override"><code>abc321
cba123
</code></pre>
<p>Login:</p>
<p>Input:</p>
<pre class="lang-none prettyprint-override"><code>abc321
</code></pre>
<p>Output (the output shouldn't be really visible, output is what the code will expect for the password input, but I added the print of <code>realPassWord</code> so I can see what the code expects):</p>
<pre class="lang-none prettyprint-override"><code>ab
</code></pre>
<p>Desired output:</p>
<pre class="lang-none prettyprint-override"><code>cba123
</code></pre>

74,249,478 | <p>I am creating a flutter Web application, but have issues when resizing the window with a SingleChildScrollView + ScrollController.</p>
<p>When I resize the browser window, the page "snaps" back up to the very top. Being a web app, most of the page "sections" are made from Columns with responsively coded widgets as children, with such widgets as Flexible or Expanded. From what I have read, the SingleChildScrollView widget doesn't work well with Flexible or Expanded widgets, so I thought that may be my issue.</p>
<p>For testing purposes, I created a new page with a single SizedBox that had a height of 3000, which would allow me to scroll. After scrolling to the bottom and resizing the window, I was still snapped up to the top of the page. Thus, with or without using Expanded or Flexible widgets, I have the same result.</p>
<p><strong>Test with a SizedBox only</strong></p>
<pre><code> @override
Widget build(BuildContext context) {
return Scaffold(
color: Colors.white,
body: SingleChildScrollView(
controller: controller.scrollController,
primary: false,
child: Column(
children: [
SizedBox(
width: 150,
height: 3000,
),
],
),
),
);
}
</code></pre>
<p>I am using Getx with this project to try getting a demo app up and running a bit quicker while I am still learning the core concepts. Below is my controller.</p>
<p><strong>Controller</strong></p>
<pre><code>class HomePageScrollControllerX extends GetxController {
late ScrollController scrollController;
@override
void onInit() {
super.onInit();
scrollController = ScrollController(
initialScrollOffset: 0.0,
keepScrollOffset: true,
);
}
}
</code></pre>
<p>Thank you in advance for any insight on this subject!</p>
<p><strong>EDIT</strong></p>
<p>I have added a listener on my ScrollController, which is able to print to the console that I am scrolling. However, the listener does not get called when I resize the window (tested in both Chrome and Edge).</p>
<p>Currently, I believe my only option is to use the listener to update an "offset" variable in the controller, and pass the window's width over to the controller when the widget rebuilds. If done properly, I should be able to use the controller to scroll to the saved offset. Something like this:</p>
<pre><code>if (scrollController.hasClients) {
if (offset > scrollController.position.maxScrollExtent) {
scrollController.jumpTo(scrollController.position.maxScrollExtent);
} else if (offset < scrollController.position.minScrollExtent) {
scrollController.jumpTo(scrollController.position.minScrollExtent);
} else {
scrollController.jumpTo(offset);
}
}
</code></pre>
<p>However, I feel like this shouldn't be necessary - and I bet this solution would be visually evident to the user.</p>
<p><strong>Edit 2</strong></p>
<p>While I did get this to work with adding the below code just before the return statement, it appears that my initial thoughts were correct. When I grab the edge of the window and move it, it pops up to the top of the window, then will jump to the correct scroll position. It looks absolutely terrible!</p>
<pre><code> @override
Widget build(BuildContext context) {
Future.delayed(Duration.zero, () {
controller.setWindowWithAndScroll(MediaQuery.of(context).size.width);
});
return PreferredScaffold(
color: Colors.white,
body: SingleChildScrollView(
controller: controller.scrollController,
......

74,249,488 | <p>I am fetching data from jsonplaceholder. It works correctly. But I want to add new position to the list using RTK query. Request is being submitted successfully, but the new item is not being added to my list.
What I am doing wrong?</p>
<p>That's my slice:</p>
<pre><code>import { createApi, fetchBaseQuery } from "@reduxjs/toolkit/query/react";
export const apiUsersSlice = createApi({
reducerPath: "apiUsersSlice",
baseQuery: fetchBaseQuery({
baseUrl: "https://my-json-server.typicode.com",
}),
tagTypes: ['Users'],
endpoints: (builder) => ({
getUsers: builder.query({
query: () => "/karolkproexe/jsonplaceholderdb/data",
providesTags: ['Users'],
transformResponse: (response) => {
const data = response.map((obj) => ({
id: obj.id,
name: obj.name,
username: obj.username,
city: obj.address.city,
email: obj.email,
}));
return data;
},
}),
addUser: builder.mutation({
query: (body) => ({
url: '/karolkproexe/jsonplaceholderdb/data',
method: 'POST',
body,
invalidatesTags: ['Users'],
}),
transformResponse: (response) => response.data,
}),
}),
});
export const { useGetUsersQuery, useAddUserMutation } = apiUsersSlice;
</code></pre>
<p>That's my store file:</p>
<pre><code>import { configureStore } from "@reduxjs/toolkit"
import { apiUsersSlice } from "./api/apiUsersSlice";
export const store = configureStore({
reducer : {
[apiUsersSlice.reducerPath] : apiUsersSlice.reducer,
},
middleware : (getDefaultMiddlewares) =>
getDefaultMiddlewares().concat(apiUsersSlice.middleware),
})
</code></pre>
<p>And of course the index file:</p>
<pre><code>import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
import { Provider } from 'react-redux';
import { ApiProvider } from "@reduxjs/toolkit/dist/query/react";
import { apiUsersSlice } from "./api/apiUsersSlice";
import {store} from './store';
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
<React.StrictMode>
<Provider store={store}>
<App />
</Provider>
</React.StrictMode>
);
</code></pre>
<p>If it's not possible to add new item to the list because of fake json server, what can I do to solve my problem?
I thought about saving data from rtk query to local storage and then to operate on it, but I found some answers that's not possible.</p>

74,249,547 | <p>I'm creating a booking reference for the user to download after successfully making a booking. It looks like this in the browser:
<a href="https://i.stack.imgur.com/yFbhU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yFbhU.png" alt="enter image description here" /></a></p>
<p>However, after using html2canvas to get a screenshot of the component in React, I get this:
<a href="https://i.stack.imgur.com/uadhy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uadhy.png" alt="enter image description here" /></a></p>
<p>I suspect the issue has to do with the fact that the static map's use is protected by an API key, causing issues to render the image in an external view.</p>
<p>This is the callback that fires on hitting the share button, which for now just downloads the png (which is then converted to pdf using jsPDF):</p>
<pre><code> const share = () => {
const input = document.getElementById("trip-summary");
if (input === null) return;
html2canvas(input!).then((canvas) => {
var image = canvas
.toDataURL("image/png")
.replace("image/png", "image/octet-stream");
const pdf = new jsPDF();
// @ts-ignore
pdf.addImage(image, "PNG", 0, 0);
pdf.save("download.pdf");
});
};

One being in ascending order and another in descending order and then joined together without changing their order.

74,249,585 | <p>First I think this is a complicated question to follow. Please see the Steps of my M code which I think will make it clearer.</p>
<p>So I am trying to achieve the following:</p>
<p><a href="https://i.stack.imgur.com/cgZpd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cgZpd.png" alt="enter image description here" /></a></p>
<p>The idea is any text in the input box can be limited to relevant sections using the parameters table If the Text in the parameters box is Contained in the Text being searched. For me, at least the question is more complicated than it first appears. If required /interested Please see my explanation below:</p>
<p><strong>Desired Output</strong>
Fundamentally I want a way of filtering the Input text, using the parameters box such that each line returned is <strong>contained</strong> only within the relevant sections of start1-End1, Start2-End2.</p>
<p>Ideally, you can use any part of the text to set the limits. So I could say Everything between SECTION1-2, and between lines 2 and 5. will returns lines 2-5.</p>
<p>Or you could say Everything between SECTION 1-3, lines 4-8. Will return lines 4-8. Note you could even say SECTION1-3, Lines 4 -SECTION 4 which would return lines 4 up to 14.</p>
<p>Finally you could even overlap sections and These should still be captured separately and the lines where overlap occurs should repeat in the output.</p>
<p>M Code:</p>
<p><strong>Parameters:</strong></p>

74,249,613 | <p>I'm trying to have a function use the autokey cipher to encrypt a message. The function has an <code>if</code> statement telling it whether to use the uppercase ASCII letters or lower case. I do not understand why that <code>if</code> statement is not working. If the letter getting ciphered is lowercase, it should use the lowercase list, but that is not the case and it keeps using the upper case list to try to cipher it, which gives me an error since the letter is not an element in the list.</p>
<pre><code>import string
# This is the variable that will hold the list of the alphabet
alphau = list(string.ascii_uppercase)
alphal = list(string.ascii_lowercase)
punctuation=list(string.punctuation)
# This is the encryption function
def encrypt(plaintext,key):
enc = ''
i = 0
for letter in plaintext:
if letter == ' ':
enc += ' '
elif letter =='\n':
enc += '\n'
else:
if letter in alphal:
x = (alphal.index(letter)+alphal.index(key[i]))%26
i += 1
enc += alphal[x]
x = ''
if letter in alphau:
x = (alphau.index(letter)+alphau.index(key[i]))%26
i += 1
enc += alphau[x]
x = ''
if letter not in alphal or alphau:
enc += letter
return enc
msg=encrypt("MyNameIsMhegazy","jMiXMyNameIsMahm")
print(msg)
</code></pre>
<pre class="lang-py prettyprint-override"><code>Traceback (most recent call last):

x = (alphau.index(letter)+alphau.index(key[i]))%26

</code></pre>
<p>I have tried using the lists in other <code>if</code> statements and they are working fine. Also tried putting strings and having a <code>for</code> loop separate upper from lower case letters using the lists and that has also worked fine. I am not sure what the problem is with the code posted above. Thanks For Your Help!</p>

74,249,617 | <p>So I'm a trying to create a function which first flips an unbiased coin but if the result is heads it flips a biased coin with 0.75 probability of heads. If it shows tails then the next flip is unbiased. I've tried the following code but I can only run this flow once i.e., if it's a head, then only the next one flip is biased and then the flow is returning to the top of the 'for' loop. Is there any recursion that I can do which can keep it inside the loop?</p>
<pre><code>def prob1():
choices = []
for _ in range (1,501):
x = random.choice(Toss_list)
if x == 0:
y = random.choices(Toss_list, weights=(0.75,0.25))
else:
y = random.choices(Toss_list, weights=(1,1))
choices.append(x)
choices.append(y)
heads = choices.count([0])+choices.count(0)
tails = choices.count([1])+choices.count(1)
return print(f'Count of heads = {heads} and count of tails = {tails}' )

<p>There is probably a simpler way to make polygons that can be subtracted from one another, but <code>sp::Polygon</code> doesn't work with <code>rgeos::gDifference</code>, so I convert to <code>SpatialPolygons</code></p>

WCGPoly<-Polygon(as.matrix(cbind(WCG$Lon,WCG$Lat)))
statesPoly<-Polygon(as.matrix(cbind(states$long,states$lat)))

p2 <- SpatialPolygons(list(Polygons(list(statesPoly), "p2")),proj4string=crdref)

<p>To visualize the difference we are trying to keep:</p>

<p><a href="https://i.stack.imgur.com/xvQSx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xvQSx.png" alt="enter image description here" /></a></p>
<p>We want to keep the red that is off the west coast (not overlapped by the states).</p>
<pre><code>library("rgeos")
Real <- gDifference(p1,p2)
</code></pre>
<p>Here I get a huge output, with errors:</p>

<p>I am assuming this is because the state polygon isn't one cohesive polygon (state borders are intact somehow and lines intersect one another, even though I only fed Lat/Lon to <code>Polygon</code>.</p>

<p>I've tried combining the "states" polygon with various forms of "union" functions (<a href="https://gis.stackexchange.com/a/63696/171788">https://gis.stackexchange.com/a/63696/171788</a>, <a href="https://gis.stackexchange.com/a/385360/171788">https://gis.stackexchange.com/a/385360/171788</a>), but this doesn't really make sense to me because most examples are using two distinct polygons, not a polygon with multiple "separated" areas like these states.</p>
<p>Trying this different answer (<a href="https://gis.stackexchange.com/a/169597/171788">https://gis.stackexchange.com/a/169597/171788</a>):</p>
<pre><code>x<- p1-p2
x<- erase(p1,p2)
</code></pre>
<p>I get the following error:</p>
<pre><code>x is invalid
Attempting to make x valid by zero-width buffering
Warning message:
In RGEOSUnaryPredFunc(spgeom, byid, "rgeos_isvalid") :
Self-intersection at or near point -122.33795166 48.281641190312918
</code></pre>
<p>Which again is telling me that my states polygon has a self-intersection. Is there a better way to trim my original polygon by the North American continent?</p>
<p>I've posted another (related) question here (<a href="https://stackoverflow.com/q/74249819/9096420">How to use `polyclip::polysimplify` on a polygon</a>) to understand how I might get rid of this self-intersection and create a solid polygon.</p>
<p>Any pointers would be greatly appreciated.</p>

74,249,761 | <p>I'm working on a C project, the goal is to reach a web server, read the data inside a file (example.com/shellcode.bin for example) and store it inside an array.</p>
<p>Currently, I managed to make the necessary GET requests, i can find my shellcode, insert it into an array (mycode) but when I return it, it sends me the wrong size.</p>
<p><strong>For example, if sizeof(mycode) return 270, sizeof(PE) return 8.</strong></p>
<p><strong>Is it possible to find the total size of the PE variable ?</strong></p>
<pre class="lang-c prettyprint-override"><code> size_t size = sizeof(mycode);
char* PE = (char*)malloc(size);
for (int i = 0; i < sizeof(mycode); i++) {
PE[i] = mycode[i];
}
printf("Shellcode size before return : %ld\n", sizeof(PE));
return PE;
</code></pre>
<p>I tried different format string outputs (%s with strlen, %d, %ld, %zu ....) all of them returned 8.</p>

74,249,764 | <p>I want to script behavior when people insert event in my calendar.
(e.g. when they add something into my "focus time"). I was able to connect an appscript "trigger" to call <code>onEventUpdate</code>. Sadly AppScript does not give you the event id for the event that was modified... (can you confirm the API does not offer this?).</p>
<p>So I tried to fetch the "last updated" events instead:</p>
<pre><code>function getOptions() {
var now = new Date();
var yesterday = new Date();
yesterday.setDate(now.getDate() - 1);
console.log(yesterday.toISOString())
return {
updateMin: yesterday.toISOString(),
maxResults: 2,
orderBy: 'updated',
singleEvents: true,
showDeleted: false
}
}
function onEventUpdate() {
var options = getOptions();
var calendarId = Session.getActiveUser().getEmail();
// var calendar = CalendarApp.getCalendarById(calendarId);
// console.log(calendar.getName());
var events = Calendar.Events.list(calendarId, options);
if(!events.items) return
for (var i = 0; i < events.items.length; i++) {
var event = events.items[i];
console.log(event.summary + " @ " + event.start['dateTime']);
}
}
</code></pre>
<p>Yet, I have just modified an event, but instead I am getting events from the past (i.e. August, 2mo ago...):</p>
<pre><code>5:11:21 PM Notice Execution started
5:11:21 PM Info 2022-10-29T00:11:21.826Z

74,249,808 | <p>See for the invoice page I have BlocBuilder wrapped in a scaffold of statful page, inside that body under several widgets is a call to future void in seperate file call to create a dialog widget. And inside the dialog method is a call to create an invoice form which is in a seprate file and is stateful class displayed to be displayed on the dialog screen. In this form the user will be able to add and delete UI elements from a list view what I need to do is rebuild the widget either dialog screen/form or the list view/ to reflect the changes made by the user</p>

<p>Edit 2: Made the follwoing changes to bloc per Mostafa answer as best I could, getting pressed against a deadline here so really need some help:
These changes were to main page calling the show dialog passing bloc.</p>
<pre class="lang-dart prettyprint-override"><code>showDialog(
context: context,
builder: (context) => BlocProvider.value(
value: blocController,
child: InvoiceDetailsDialog(
screenWidth: screenWidth,
screenHeight: screenHeight),
),
);
</code></pre>
<p>This file was the original place where showdialog was called and was custom Future return showDialog.
Results: showDialog takes enitre screen. Rendering Invoice form reulsts in error being displayed in place of the form:</p>
<pre class="lang-dart prettyprint-override"><code>No Material widget found.
</code></pre>
<p>Edit 3: fixed previous error but back where i started bloc is still being called succesfully but no changes to the ui:</p>
<pre class="lang-dart prettyprint-override"><code>Widget build(BuildContext context) {
final blocController = BlocProvider.of<InvoiceBlocController>(context);
return Center(
child: Material(color: Colors.red,
borderRadius: BorderRadius.circular(50),
child: SizedBox(
width: screenWidth / 2, height: screenHeight / 2,
child: Padding(padding: const EdgeInsets.all(20),
child: Column(children: [
Expanded(child: ListView(children: [
Text('Invoices',
style: Theme.of(context)
.textTheme.bodyLarge?.copyWith(color: Colors.white)),
InvoiceForm()
]))])))));
}
</code></pre>
<p>As form nothing changed except instead of passing the blocController through a method I am now calling it like:</p>
<pre class="lang-dart prettyprint-override"><code>class _InvoiceFormState extends State<InvoiceForm> {
final _formKey = GlobalKey<FormState>();
late final InvoiceBlocController blocController;
@override
void initState() {
blocController = BlocProvider.of<InvoiceBlocController>(context);
super.initState();
}
</code></pre>
<p>Still nothing changes.</p>
<p>Edit 4: Set state does work and leaving in bloc code was excuting and if I clicked add two items would be added or delete would remove two items. But with setstate commented out it went back to not rebuilding. Using setstate for now but not preffered.</p>
<p>Edit 5: Don't if thiss is still being paid attention to hopfully is. Can I keep add add events like: add(NewItem), add(deleteItem),add(GeneratePDF). Without changing state. currently I have done that once so far. Is this bad practice</p>

74,249,995 | <p>Very new to coding. I have 2 tables, zips_usa which includes all properly formatted zips (zipcode, lat / lon / city / state etc) in the US, and table ageus which includes columns such as first name, last name, category, comments. It took 3 weeks to write the zipcode radius search but I got there, mainly due to answers I found on this site. Thanks.
I now need help dealing with the output. I think I need a join statement between the tables and cannot get my head around the logic. Any help would be appreciated.</p>
<p>sql statement for zip radius search runs error free. Input is performed by a html form.</p>
<pre><code> $sql = "SELECT latitude, longitude FROM zips_usa WHERE zipcode = '$zipcode'";
</code></pre>
<p>Table ageus column details (where users post to)</p>
<p>id first_name last_name dog_type comments city state entered gender category zipcode</p>
<p>How do I join the two tables so I can select output that includes all info from table ageus that includes zip codes found within the X mile radius?</p>

74,250,107 | <p>My code obtains certain paragraphs from a textbook. I would like the code to spit out several versions of this paragraph using some sort of paraphrasing tool, automatically. The code is written mostly in Python, but also uses Js (and Ts) for certain aspects.</p>
<p>I tried implementing several completed models, including;
(python) Pytorch, parrot, scpn, and others, but it quickly became too complicated for me. Can someone help me write a better way, or help me use an already made model? Thank you <3</p>

74,250,115 | <p>When I add or edit a customer in Customer table, it does not appear in customer filed of Sales table, so I have to destroy the window and open it again manually or with refresh button.
The refresh button also work 1 time, means when I add or edit another customer in Customer table, then click the refresh button just the window destroy.
How to solve this problem without a refresh button means when I add or edit a customer in Customer table Immediately appear in customer filed of Sales table?</p>

74,250,127 | <p>As soon as I try to access a folder/file containing an emoji in its name from my Lua 5.2 script, for example like this:</p>
<pre><code>os.execute('start "" "' .. path .. "\\scripts\\menu\\ My Scripts" .. '"')
</code></pre>
<p>The Windows' Command Prompt simply refuses to open it with the following error message:</p>
<p><a href="https://i.stack.imgur.com/KnHpT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KnHpT.png" alt="CMD and emoji in path issue" /></a></p>
<p>I'm aware Windows' Command Prompt doesn't support emojis and therefore is not possible to make it work just like that, but my doubt is if won't exist some workaround or whatever I can do to ensure any Windows/Unix user is going to able to get the folder open by my Lua script without any problem.</p>
<p>I have tried i.e. things like use the codes instead (1246 and U+1F4F0 in this <em>page facing up</em> case) without success. Couldn't I for example simply use some kind of "wildcard" instead? I mean, knowing it's always going to be the very first character in the name. Or, well, any other ideas will be welcomed, cause nothing I'm trying really seems to work...</p>
<p>Of course if it's going to represent any problem I'll simply refuse to use them, but it came in handy for some "first sight" folder distinction and, if possible, I'd like to can count this little visual resource </p>

74,250,142 | <p>How do you rename any response/value to 1 and any NA to 0?</p>
<p>Sample Dataframe:</p>
<pre><code>Dataframeexample <- data.frame(Q5 = c("potato", "chips", "chips", "chips,potato","icecream,chips,potato", "icecream,potato", "chips", "NA", "NA"))
</code></pre>
<p>My actual dataframe has hundreds of potential combinations, so renaming each potential value individually isn't feasible.</p>

74,250,159 | <p>I have a payload like below:</p>
<pre><code>{
"data": [
{
"id": "f251f05f-038c-4c26-bf7c-3b2fc47210e6",
"specialtyIds": [
"20c5f3f0-54c9-4779-b1a3-19baeee91b4a"
]
},
{
"id": "61d34a84-940d-4556-9c4b-ef7bede9caca",
"specialtyIds": [
"20c5f3f0-54c9-4779-b1a3-19baeee91b4a",
"9834e1cf-94c4-4188-83e6-867ac1d60017",
"30d6g4d3-54c9-4779-b1a3-19baeee92cdc"
]
}
]
}
</code></pre>
<p>and want to return an array like:</p>
<pre><code>[
{
id: "20c5f3f0-54c9-4779-b1a3-19baeee91b4a"
},
{
id: "9834e1cf-94c4-4188-83e6-867ac1d60017"
},
{
id: "30d6g4d3-54c9-4779-b1a3-19baeee92cdc"
}
]
</code></pre>
<p>I've used the following dataweave which works fine when <code>specialtyIds</code> is only one element. But the second there's more than one element it breaks:</p>
<pre><code>payload.data map {
id: $.specialtyIds joinBy(",")
} distinctBy $
</code></pre>
<p>if the array has more than two elements the script returns:</p>
<pre><code>[
{
id: "20c5f3f0-54c9-4779-b1a3-19baeee91b4a"
},
{
id: "20c5f3f0-54c9-4779-b1a3-19baeee91b4a,9834e1cf-94c4-4188-83e6-867ac1d60017"
}
]
</code></pre>
<p>I am relatively new to dataweave, but have explored pluck and reduce to iterate over the arrays but haven't had much luck. I feel like there is probably a simpler way to tackle this structure.</p>
