74,224,926 | <p>When we build an executable, and it gets loaded into RAM, my understanding is that the <code>.text</code> and <code>.ro</code> setions should be loaded into read-only memory locations. With an operating system and a virtual memory controller I can understand how the different sections could get loaded to the right memory locations.</p>
<p>However, considering a bare-metal system without an operating system and an ARM chip for example. How is the read-only attribute of those sections achieved. They could be stored in ROM or Flash? But then doesn't everything get loaded into RAM anyways? Thanks in advance.</p>

74,225,012 | <p>I have an assignment for class that tasks me with creating a function in R that takes in a vector of values and converts them between Fahrenheit, Celsius and Kelvin. The example that I try to run through my code should produce a return vector that contains only 3 values, yet it is returning a vector that holds 26 values.</p>
<p>Here is my code below:</p>
<pre><code>convTemp <- function(x, from = "C", to = "F") {
newX <- vector("double", length(x))
if (from == to) {
warning("Your 'from' parameter is the same as your 'to' parameter!") # From and To are same temperature scale
}
if (from == "C" && to == "F") { # Celsius to Fahrenheit
for (i in x) {
newX[i] <- ((9/5)*x[i]+32)
}
}
if (from == "C" && to == "K") { # Celsius to Kelvin
for (i in x) {
newX[i] <- (x[i]+273.15)
}
}
if (from == "F" && to == "C") { # Fahrenheit to Celsius
for (i in x) {
newX[i] <- ((x[i]-32)*(5/9))
}
}
if (from == "K" && to == "C") { # Kelvin to Celsius
for (i in x) {
newX[i] <- (x[i]-273.15)
}
}
if (from == "F" && to == "K") { # Fahrenheit to Kelvin
for (i in x) {
newX[i] <- ((((x[i]-32)*5)/9)+273.15)
}
}
if (from == "K" && to == "F") { # Kelvin to Fahrenheit
for (i in x) {
newX[i] <- ((((x[i]-273.15)*9)/5)+32)
}
}
return(newX)
}
convTemp(c(35,40,45), from="F", to="K")
</code></pre>
<p>And here is the output I'm receiving:</p>
<pre><code> [1] 0 0 0 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
[26] NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
</code></pre>
<p>So I'm not sure why the function is returning such a large vector of missing values when it should be returning a vector of 3 Kelvin values.</p>

74,225,051 | <p>I have to implement a system where a tenant can store multiple key-value stores. one key-value store can have a million records, and there will be multiple columns in one store</p>
<p>[Edited] I have to store tabular data (list with multiple columns) like Excel where column headers will be unique and have no defined schema.
This will be a kind of static data (eventually updated).
We will provide a UI to handle those updates.
Every tenant would like to store multiple table structured data which they have to refer it in different applications and the contract will be JSON only.</p>
<p>For Example, an Organization/Tenant wants to store their Employees List/ Country-State List, and there are some custom lists that are customized for the product and this data is in millions.</p>
<p>A simple solution is to use SQL but here schema is not defined, this is a user-defined schema, and though I have handled this in SQL, there are some performance issues, so I want to choose a NoSQL DB that suits better for this requirement.</p>
<p>Design Constraints:</p>
<ol>
<li>Get API latency should be minimum.</li>
<li>We can simply assume the Pareto rule, 80:20 80% read calls and 20% write so it is a read-heavy application</li>
<li>Users can update one of the records/one columns</li>
<li>Users can do queries based on some column value, we need to implement indexes on multiple columns.</li>
<li>It's schema-less so we can simply assume it is NoSql, SQL also supports JSON but it is very hard to update a single row, and we can not define indexes on dynamic columns.</li>
<li>I want to segregate key-values stores per tenant, no list will be shared between tenants.</li>
</ol>
<p>One Key Value Store :</p>
<p><a href="https://i.stack.imgur.com/O35uG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/O35uG.png" alt="enter image description here" /></a></p>
<p>Another key value store example: <a href="https://datahub.io/core/country-list" rel="nofollow noreferrer">https://datahub.io/core/country-list</a></p>
<p>I am thinking of Cassandra or any wide-column database, we can also think of a document database (Mongo DB), every collection can be a key-value store or Amazon Dynamo database</p>
<p>Cassandra: allows you to partition data by partition key and in my use case I may want to get data by different columns in Cassandra we have to query all partitions which will be expensive.</p>

74,225,052 | <p>I have been trying to use Split and Filter to display ONLY the duplicate zip codes within a column list of zip codes. Column A shows location name (irrevelant) and column B is a comma-separated list of zips. In column C+ I want only the zip codes that are a duplicate of the entire column B to be shown.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Location Name</th>
<th>Zip Code List</th>
<th>[Output]Col C</th>
<th>Col D</th>
<th>Col E</th>
</tr>
</thead>
<tbody>
<tr>
<td>Home 1</td>
<td>37075,37066,37072</td>
<td>37075</td>
<td>37066</td>
<td>37072</td>

<tr>
<td>Home 2</td>
<td>37066,37072</td>
<td>37066</td>

<p>In this case above, Column C, D, E are the expected output.</p>
<p>I currently have the following in cell C2
<code>=filter(split(B2,","),arrayformula(countif(split(B2,","),B2)>1))</code></p>
<p>But this is not working.</p>

alt.Chart(df_avg)
.mark_line(strokeDash=[5, 5])
.encode(
x=alt.X("date:N", title="Date", sort=None),
y=alt.Y(

74,225,112 | <p>I have a table listing my todos. In the last column, I have a button to mark the todo as finished. Because I'd like to reuse this button in other tables and views, I've added it as a component that is being imported.</p>
<p>Furthermore, I'd like to use a table package such as <code>vue3-table-lite</code> so that I can have quick and easy access to 1) filtering, 2) pagination, and 3) sorting features.</p>
<p>These packages typically uses <code>:rows</code>, which is pretty straightforward if you only have text. However, I don't know how to provide Vue components, in this case <code><FinishedButton /></code> from the last <code><td></code> shown in the last code block below.</p>
<p><strong>How can I import Vue components into <code>:rows</code> of a table? Alternatively achieve filtering, pagination, and sorting without having to use <code>:rows</code> at all.</strong></p>
<hr />
<p>Here's how the button component is constructed:</p>
<pre><code><template>
<a v-show="todo.is_finishable" v-on:click="markFinished(todo.id)"
class="todo_finished btn btn-sm btn-light btn-light-border finalized_button">Finished</a>
</template>
<script>
export default {
name: 'FinishedButton',
props: ['todo',],
methods: {
remove: function () {
this.$emit("delete", this.todo);
},
markFinished: function (selected_todo_id) {
this.$http.patch('/api/todo/' + selected_todo_id + "/", {
status: 'Done'
})
.then(response => {
console.log(response);
this.remove();
})
.catch(e => {
console.log(e);
});
}
},
};
</script>
</code></pre>
<p>Here's how a simplified version of the table looks like (there's more columns in the actual table):</p>
<pre><code><table id="FOO" class="table table-hover table-sm">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Action</th>
</tr>
</thead>
<tbody>
<tr v-for="todo in todos" :key="todo.id">
<td>{{ todo.name }}</td>
<td><FinishedButton :todo=todo /></td>
</tr>
</tbody>
</table>

It's causing a buffer overflow error? Pretty sure it's from strcat from searching online but I'm not sure. Any help is appreciated! Also please don't use * in your answer, because I don't know how they work, I will learn very soon. (if its required for your answer, explain how you use it in the code please)</p>
<p>heres the code:</p>
<pre><code>#include <string.h>
int findIndex(char string[], char substr) {
for (int index = 0; index < strlen(string); index++) {
if (string[index] == substr) {
return index;
}
}
return -1;
}
int main(void) {
char howAreYou[9] = "howAreYou";
char newString[9];
int index = findIndex(howAreYou, 'o');
for (int i = 0; i < 8; i++) {
if (i != index) {
strncat(newString, &howAreYou[i], 1);
}
}
printf("new string: %s", newString);
return 0;
}
</code></pre>

74,225,175 | <p>I have a data.table that I am trying to filter. Basically, for any row that has a value of "--" (they are all characters, and that was put in place of NA) in any one of about 750 columns, I want to delete that row.</p>
<p>Here is a sample dataset:</p>
<pre><code>library(tidyverse)
library(data.table)
snp <- c(1:5)
id1 <- c("AA", "AB", "BB", "--", "AA")
id2 <- c(rep("AA", 5))
id3 <- c("BB", "AB", "--", "AA", "AA")
data1 <- as.data.table(cbind(snp, id1, id2, id3))
data1
</code></pre>
<p>I also have a version of this dataset that is transposed, so I could filter out any column that has "--" in it, but I figured filtering rows would be easier.</p>
<p>Since there are hundreds of columns with strange names, I can't write out a function that includes each one with & between each one, such as:</p>
<pre><code>data2 <- data1 %>%
filter(id1 != "--" & id2 != "--" & id3 != "--")
data2
</code></pre>
<p>How can I filter based on every column at once with so many columns?</p>
<p>Thank you!</p>
<p>P.S. I know this sounds easy, but I have been searching for an answer for awhile and have come up dry.</p>

74,225,221 | <p>I came up with a solution but it does not perform well enough to pass with very large inputs. Any way of maybe doing it without iterating?</p>
<blockquote>
<p>Challange:
Given a sequence of integers as an array, determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array.</p>
<p>Note: sequence a0, a1, ..., an is considered to be a strictly increasing if a0 < a1 < ... < an. Sequence containing only one element is also considered to be strictly increasing.</p>
<p>Example</p>
<p>For sequence = [1, 3, 2, 1], the output should be
solution(sequence) = false.</p>
<p>There is no one element in this array that can be removed in order to get a strictly increasing sequence.</p>
<p>For sequence = [1, 3, 2], the output should be
solution(sequence) = true.</p>
<p>You can remove 3 from the array to get the strictly increasing sequence [1, 2]. Alternately, you can remove 2 to get the strictly increasing sequence [1, 3].</p>
<p>Input/Output</p>
<p>[execution time limit] 4 seconds (py3)</p>
<p>[input] array.integer sequence</p>
<p>Guaranteed constraints:
2 β€ sequence.length β€ 105,
-105 β€ sequence[i] β€ 105.</p>
<p>[output] boolean</p>
<p>Return true if it is possible to remove one element from the array in order to get a strictly increasing sequence, otherwise return false.</p>
</blockquote>
<p>My solution is below and it seems to work however it does not perform well enough with very large inputs to count as a solution.</p>
<p>My Solution:</p>
<pre><code>def solution(sequence):
for number in range(len(sequence)):
shortened = sequence.copy()
shortened.pop(number)
if len(shortened) == len(set(shortened)):
if shortened == sorted(shortened):
return True
return False

74,225,252 | <p>I'm a bit stuck on an exercice I have to make and I can't figure out the best way to do it.</p>
<p>I have to make a method that asks a question and expects Y or N. So I thought I would make a boolean method to return true or false, but the problem is that it would also return false if the user puts something other than Y or N. If I'm not mistaken, a boolean method cannot return null.</p>
<p>I'm very new to java and I'm not very far in my course so this problem will probably have a very simple solution. I also tried looking for an answer but didn't seem to find what I was looking for.</p>
<p>This is what I have with the boolean method but i'm not quite happy with it:</p>
<pre><code> public static boolean test() {
Scanner sc = new Scanner(System.in);
System.out.println("question");
String reponse = sc.next();
if (reponse.equalsIgnoreCase("Y")) {
return true;
}
else if (reponse.equalsIgnoreCase("N")) {
return false;
}
else {
return false;
}
}

74,225,257 | <p>The question has changed since its initial posting as I've chased down a few leads. At this point, I'd say that I'm really looking for the following answers:</p>
<ol>
<li><p>Can a significant amount of time be saved by replacing addition/multiplication followed by a modulo 2 operation with and/logical_xor (assuming that the total number of such operations is kept the same)? If not, then why not? <em>ANSWER: some time can indeed be saved, but it's arguable whether that amount is "significant"</em>.</p>
</li>
<li><p>Where can I read more about the specific approach taken by the BLAS matrix multiplication underlying numpy? Ideally, I'd like a source that doesn't require deciphering the FORTRAN code forged by the sages of the past. <em>ANSWER: The original paper proposing the BLAS matrix multiplication algorithms used today <a href="https://www.researchgate.net/publication/234792010_A_Set_of_Level_3_Basic_Linear_Algebra_Subprograms" rel="nofollow noreferrer">can be found here</a></em>.</p>
</li>
</ol>
<p>I've left my question in its original form below for posterity.</p>
<hr />
<p>The following are two algorithms for multiplying binary matrices (i.e. taking the "dot" product) modulo 2. The first ("default") approach just uses numpy matrix-multiplication, then reduces modulo 2. The second ("alternative") approach attempts to speed things up by replacing the addition operation with an xor operation.</p>
<pre><code>import timeit
import numpy as np
import matplotlib.pyplot as plt
def mat_mult_1(A,B):
return A@B%2
def mat_mult_2(A,B):
return np.logical_xor.reduce(A[:,:,None]&B[None,:,:],axis = 1)
</code></pre>
<p>Contrary to my expectations, the alternative approach seems to take about 4 times longer than the default for products of larger binary matrices. Why is that? Is there some way I could speed up my alternative approach?</p>
<p>Here's the script I used to test the above two methods</p>
<pre><code>n_vals = np.arange(5,205,5)
times = []
for n in n_vals:
s_1 = f"mat_mult_1(np.random.randint(2,size = ({n},{n}))\
,np.random.randint(2,size = ({n},{n})))"
s_2 = f"mat_mult_2(np.random.randint(2,size = ({n},{n})),\
np.random.randint(2,size = ({n},{n})))"
times.append((timeit.timeit(s_1, globals = globals(), number = 100),
timeit.timeit(s_2, globals = globals(), number = 100)))
</code></pre>
<p>and here are two plots of the results.</p>
<p><a href="https://i.stack.imgur.com/bPUXj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bPUXj.png" alt="enter image description here" /></a></p>
<hr />
<p>Minor updates:</p>
<p>I was able to test these out for larger matrices (up to 1000x1000) and get a better sense of the asymptotics here. It indeed seems to be the case that the "default" algorithm here is O(n<sup>2.7</sup>), whereas the alternative is the expected O(n<sup>3</sup>) (the observed slopes were 2.703 and 3.133, actually).</p>
<p><a href="https://i.stack.imgur.com/XjUrd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XjUrd.png" alt="enter image description here" /></a></p>
<p>I also checked how the alternative algorithm compared to the following implementation of "schoolbook" matrix multiplication followed by a mod operation.</p>
<pre><code>def mat_mult_3(A,B):
return np.sum(A[:,:,None]*B[None,:,:],axis = 1)%2
</code></pre>
<p>I was very surprised to find that this <strong>also</strong> does better than the and/xor based method!</p>
<p><a href="https://i.stack.imgur.com/dsb8l.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dsb8l.png" alt="enter image description here" /></a></p>
<p>In response to Michael's comment, I replaced <code>mat_mult_2</code> with the following:</p>
<pre><code>def mat_mult_2(A,B):
return np.logical_xor.reduce(A.astype(bool)[:,:,None]
& B.astype(bool)[None,:,:],axis = 1).astype(int)
</code></pre>
<p>This arguably still places an undue burden of type conversion on the method, but sticking to multiplication between boolean matrices didn't significantly change performance. The result is that <code>mat_mult_2</code> now (marginally) outperforms <code>mat_mult_3</code>, as expected.</p>
<p><a href="https://i.stack.imgur.com/rBLvE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rBLvE.png" alt="enter image description here" /></a></p>
<p>In response to Harold's comment: another attempt to get the asymptotics of the <code>@</code> method. My device doesn't seem to be able to handle multiplication with n much greater than 2000.</p>
<p>The observed slope here is 2.93.</p>
<p><a href="https://i.stack.imgur.com/Nx2uv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Nx2uv.png" alt="enter image description here" /></a></p>

74,225,268 | <p>I am developping a WPF application in XAML. I am a beginner and I have an issue with my button. I need to set its height as a proportion of its container which is a grid. I saw that the height can be set to a value or to "Auto", but I don't know how to say to my button that his height must be 3/4 of the height of the grid in which it is contained.</p>
<p>Does anybody know how to deal with that ? Is it possible to do that with XAML ?</p>
<p>The objective is that when the grid grows, the button grows with it.</p>
<p>Any help would be appreciate.</p>
<p>Thanks</p>

<Button Content="Button 1" FontSize="30" Height="75" Width="150"/>
</Grid>
</Grid>

<p>For the button, instead of Height="75", I would like to say Height=0.75 * Grid Height</p>

74,225,302 | <p>I'd always assumed a threading.Lock object would act as a mutex to prevent race conditions from occuring in a multithreading Python script, but I'm finding that either</p>

<li>Python itself has a bug (in, at the very least, versions 2.7-3.9) regarding this.</li>

74,225,453 | <p>I'm new to git, and I can't find an answer for that which is kind of weird.
Here is my problem:
I want to commit changes to all files within my folder called "folder1"
here is the content of "folder1":</p>
<pre><code>folder1
pyproject1.py
pyproject2.py
myimg.png
</code></pre>
<p>To do that, I commit my changes to my github repository, using the following command lines:</p>
<pre><code>git add *
git commit-m"my changes"
git push origin main
</code></pre>
<p>But if I try to remove for example the file "myimg.png" from my local folder, and execute again the following command lines:</p>
<pre><code>git add *
git commit-m"my changes"
git push origin main
</code></pre>
<p>The file myimg.png isn't removed from the github repository. How can I make sure that every time I commit a change in my local folder, every file that is not anymore in my local folder gets deleted from the repository ?</p>

74,225,466 | <p>Hope you all are doing well in these times.</p>
<p>here's my code:</p>
<pre><code>
def ab(n):
first = 0
last = -1
endprod = n[first] + n[last]
endprod2 = n[first+1] + n[last-1]
endprod3 = n[first+2] + n[last-2]
endprod4 = n[first+3] + n[last-3]
endprod5 = n[first+4] + n[last-4]
endprod100 = endprod[::-1] + endprod2[::-1] + endprod3[::-1]+ endprod4[::-1]+ endprod5[::-1]
return endprod100
</code></pre>
<p>I was able do to it, however mine isn't a loop. Is there a way to convert my code into a for loop. So, increment by 1 and decrement by 1.</p>
<p>Thanks,</p>

74,225,482 | <p>IΒ΄ve been trying to automize a list of addresses in SQL. I have multiple addresses and quantities and i need only the addresses that will fulfill the quantity i need</p>
<p>For example:</p>
<p>I have a table with</p>
<pre><code>Item A qty 20
Item B qty 5
Item C qty 23
</code></pre>
<p>And a table with addresses and units</p>
<pre><code>Address 1 item A 15units
Address 2 item A 10units
Address 3 item A 10units
Address 4 item A 13units
</code></pre>
<p>The result should show only</p>
<pre><code>Address 2 item A 10units
Address 3 item A 10units

74,225,490 | <p>My code is as follows:</p>
<pre><code>import random
players = []
def player_list(new_player):
for x in range (5):
players.append(new_player)
return players
for x in range (5):
new_player = input("Please enter your player name: ")
winner=(random.choice(players))
print("You are the winner," , winner)
</code></pre>
<p>It keeps returning the following error message:</p>
<pre class="lang-none prettyprint-override"><code>Please enter your player name: Rashida
Traceback (most recent call last):
Random Role Assignment Program.py", line 11, in <module>
mafia=(random.choice(players))
File "C:\Users\Student\AppData\Local\Programs\Python\Python310\lib\random.py", line 378, in choice
return seq[self._randbelow(len(seq))]
IndexError: list index out of range
</code></pre>
<p>The code is supposed to fill up an empty list and the return it. I checked this and it didn't work.
Then the code is supposed to randomly select a player and tell them they won.</p>
<p>How do I fix this?</p>
<p>The code may not be perfect in other aspects either.</p>

74,225,513 | <p>I'm gradually moving a RN project to typescript. I have a question about declaring types for styles that are being passed as a props to a component.</p>
<p>The Props within the component are defined as follows:</p>
<pre><code>interface Props {
children: ReactNode;
style?: ViewStyle;
}
</code></pre>
<p>It's ok if I pass just a simple styles object, eg:</p>
<pre><code><Component style={{ marginTop: 1 }}>...children...</Component>
<Component style={styleObj}>....children...</Component>
</code></pre>
<p>But it fails if I pass an array of styles:</p>
<pre><code><Component style={[styleObj, { marginTop: someVar }]}>...children...</Component>
</code></pre>
<p>What would be the best way to specify the style prop type?</p>
<p>EDIT: and the TS message is:</p>
<pre><code>TS2559: Type '({ flex: number; } | { marginTop: number; })[]' has no properties in common with type 'ViewStyle'. Component.tsx(12, 3): The expected type comes from property 'style' which is declared here on type 'IntrinsicAttributes & Props'
</code></pre>

74,225,523 | <p>I have a large csv where each row is a separate school course, each of which is tagged with one or more topics, like so:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>school name</th>
<th>department</th>
<th>course name</th>
<th>topics</th>
</tr>
</thead>
<tbody>
<tr>
<td>A</td>
<td>A1</td>
<td>X</td>
<td>1; 2</td>
</tr>
<tr>
<td>A</td>
<td>A1</td>
<td>Y</td>
<td>1; 3</td>
</tr>
<tr>
<td>B</td>
<td>B1</td>
<td>Z</td>
<td>1; 2; 4</td>
</tr>
<tr>
<td>C</td>
<td>C1</td>
<td>XX</td>
<td>1; 5</td>
</tr>
</tbody>
</table>
</div>
<p>I need to calculate the presence of each topic for each course. Each topic needs to be appended as its own column, with each row coded as either a 0 or 1 depending on whether the topic is present in the course. There are 49 topics in total, so I need to add 49 rows to the table.</p>
<p>There are 4000 rows, many of which are repeats of the same course name, so those need to be grouped as well. For example, if one instance of course name X has topics 1, 2 but another instance of the same course has topics 1, 3 the binary values for column topic 1 should be 1, topic 2 should be 1, and topic 3 should be 1, while the rest of the topic columns are coded as 0.</p>
<p>The output should look something like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>school name</th>
<th>department</th>
<th>course name</th>
<th>topic 1</th>
<th>topic 2</th>
<th>topic 3</th>
<th>topic 4</th>
<th>topic 5</th>
</tr>
</thead>
<tbody>
<tr>
<td>A</td>
<td>A1</td>
<td>X</td>
<td>1</td>
<td>1</td>
<td>0</td>
<td>0</td>
<td>0</td>
</tr>
<tr>
<td>A</td>
<td>A1</td>
<td>Y</td>
<td>1</td>
<td>0</td>
<td>1</td>
<td>0</td>
<td>0</td>
</tr>
<tr>
<td>B</td>
<td>B1</td>
<td>Z</td>
<td>1</td>
<td>1</td>
<td>0</td>
<td>1</td>
<td>0</td>
</tr>
<tr>
<td>C</td>
<td>C1</td>
<td>XX</td>
<td>1</td>
<td>0</td>
<td>0</td>
<td>0</td>
<td>1</td>
</tr>
</tbody>
</table>
</div>
<p>I have a nested loop structure that splits the topics by semicolon and then does some cleaning to standardize the topic names, but I'm stuck on how to append a new column for each topic coded as the correct binary value.</p>
<pre><code>import pandas as pd
import io
df = pd.read_csv(io.BytesIO(uploaded['courses.csv']))
df_dict = {}
result = []
topic = []
count = []
for item in df['Course ID']:
for item in df['Final Code']:
if type(item) == str:
item_list = item.split(';')
for each in item_list:
each = each.strip().lower()
if each == "[too ambigious]" or each == "too ambiguous":
each = "[too ambiguous]"
if each == "equity and equality\\":
each = "equity and equality"
if each == "[NA]" or each == "N/A":
each = "NA"
#create new column for each unique topic
for item in df['Final Code']:
result.append(item)
#1 if that topic is present in each course, else 0
if each in df_dict:
df_dict[each] = 1
else:
df_dict[each] = 0
print(df_dict)
print(result)
print(df)
</code></pre>
<p>I haven't used python for a long time, so I forget how to go about this.</p>

74,225,572 | <p>I have an html page where some words are split by <code>&#8203;</code> so they look e.g. like <code>ββFβRigβVβMβExternalβVariable</code> but in the code they are actually <code>F&#8203;Rig&#8203;V&#8203;M&#8203;External&#8203;Variable&#8203;</code>. And the problem is that when I click the word it selects only a part that is bordered by <code>&#8203;</code> while the desirable behavior is for it to select the whole word</p>
<p>How to override default double click behavior in JS so it would treat <code>&#8203;</code> not as a word boundary?</p>

74,225,641 | <p>I have read in a monthly temperature anomalies csv file using Pandas read.csv() function. Years are from 1881 to 2022. I excluded the last 3 months of 202 to avoid -999 values). Date format is yyyy-mm-dd. How can I just plot the year and only one value instead of 12 on the x-axis (i.e., I don't need 12 1851s, 1852s, etc.)?</p>
<pre><code>import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from matplotlib.dates import YearLocator, MonthLocator, DateFormatter
import matplotlib.dates as mdates
ds = pd.read_csv('path_to_file.csv', header='infer', engine='python', skipfooter=3)
dates = ds['Date']
tAnoms = ds[' Berkeley Earth 2m Air Temperature (degree C) 0N-90N;0E-360E']
fig = plt.figure(figsize=(10,10))
ax = plt.subplot(111)
ax.plot(dates,tAnoms)
ax.plot(dates,tAnoms.rolling(60, center=True).mean())
ax.xaxis.set_major_locator(mdates.YearLocator(month=1) # EDIT
years_fmt = mdates.DateFormatter('%Y') # EDIT 2
ax.xaxis.set_major_formatter(years_fmt) # EDIT 2
plt.show()
</code></pre>
<p>EDIT: adding the following gives me the 2nd plot
EDIT 2: Gives me yearly values, but only from 1970-1975. 3rd plot</p>

74,225,658 | <p>I'm making a navbar and for each button, I have a <div> and a , the div is the box and the a is the text+hyperlink.</p>
<p>I want to have my div change colors when I hover it, the problem is if I add a div :hover to my CSS it only changes colors when I hover over the , and not the div. So the box only changes colors when I hover the text.</p>
<p>I'm also having to copy everything from my normal div to the hover div because if I only change the color only the text will. (the last image is what it looks like when my div hover has only a background-color property)
The red circles on the images are where my mouse is.</p>
<p>I hope it didn't sound too confusing.
Code and example below:</p>
<pre><code>(this is inside a <nav>)
<div class="menu">
<div class="mapbox"><a class="map" href="">Erangel</a><br></div>
<div class="mapbox"><a class="map" href="">Miramar</a><br></div>

74,225,736 | <p>In Julia, I want to stack heatmaps in one plot, just how it was done with Matlab in this stackoverflow post:
<a href="https://stackoverflow.com/questions/59749646/i-need-a-function-to-display-matrices-stacked">I need a function to display matrices stacked</a>
Preferably with the same color bar for all heatmaps, and with the ability to specify the position of each plane (i.e. along the third dimension).</p>
<p>I know how to stack surface plots by adding an offset to each surface (see this page: <a href="https://plotly.com/julia/3d-surface-plots/" rel="nofollow noreferrer">https://plotly.com/julia/3d-surface-plots/</a>), but this is not what I want to achieve as a surface plot is not flat, but, as the name suggests, a <em>surface</em>. My workaround currently is to use an offset large enough that each surface <em>appears</em> to be flat, but as the third axis relates to the real world height of my measurements, I am not happy with this fix.</p>
<p>What I would prefer is a parameter <code>positions_z = [z1, z2, z3, ...]</code> that specifies the location of all heatmaps along the third axis, but I am also happy with workarounds.
Does anyone know a solution?</p>

74,225,763 | <p>I'm trying to get multiple values from different cells in a sheet in Google Sheets and add in another sheet, but I couldn't figure out how to do it with setValue and getValue functions.</p>

var arrayCells = [

dataS.getRange(dataS.getLastRow()+1,1,1,2).setValue(arrayCells.getValue());
}

<p>And if I use, I don't get any value from the variables added to Base1, only a new row:</p>
<pre><code> dataS.getRange(dataS.getLastRow()+1,1,1,2).setValue(arrayCells);
</code></pre>
<p>Before I was using <strong>appendRow()</strong> and added <strong>.getValue()</strong> after the variables in the array, but I was getting problems with the other function I create to clean all the cells after saving, using <strong>for</strong> and <strong>getRange</strong>.</p>
<p>Was something like:</p>
<pre><code> var arrayCells = [
cellNome.getValue(),
cellSobrenome.getValue()
];
dataS.appendRow(arrayCells);
</code></pre>
<p>And the function to clean the cells, but it doesn't work with variable.getValue():</p>
<pre><code> for ( var i = 0 ; i < arrayCells.length ; i++ ) {
arrayCells[i].clearContent();

74,225,832 | <p>My first Flutter project, which is a tricycle booking system, has just begun. Using the ListView widget, I wanted to display all of the active passengers that are saved in my Firebase Database. However, when I attempted to display it and place it in a List, all functions are working fineΒ at first click. When you click the button to view theΒ ListView a second time, all of the saved data are replicated. The list continues after my third click and grows by three. The image below illustrates what takes place when I repeatedly click on the ListView.</p>
<p>These are the blocks of code that are utilized for this functionality:</p>
<p><strong>CODE for Functionality</strong></p>
<pre><code>retrieveOnlinePassengersInformation(List onlineNearestPassengersList) async
{
dList.clear();
DatabaseReference ref = FirebaseDatabase.instance.ref().child("passengers");
for(int i = 0; i<onlineNearestPassengersList.length; i++)
{
await ref.child(onlineNearestPassengersList[i].passengerId.toString())
.once()
.then((dataSnapshot)
{
var passengerKeyInfo = dataSnapshot.snapshot.value;
dList.add(passengerKeyInfo);
print("passengerKey Info: " + dList.toString());
});
}
}
</code></pre>
<p><strong>CODE for the UI</strong></p>
<pre><code>body: ListView.builder(
itemCount: dList.length,
itemBuilder: (BuildContext context, int index)
{
return GestureDetector(
onTap: ()
{
setState(() {
chosenPassengerId = dList[index]["id"].toString();
});
Navigator.pop(context, "passengerChoosed");
},
child: Card(
color: Colors.grey,
elevation: 3,
shadowColor: Colors.green,
margin: EdgeInsets.all(8.0),
child: ListTile(

74,225,877 | <p>When module A imports B, and B imports A, I get error:
<code>ImportError: cannot import name from partially initialized module (most likely due to a circular import)</code>.</p>
<p>However, if I merge contents of both modules into one, no error happens. Is there a reason why python does not treat circularly imported files as one big one?</p>
<p>I understand, that ambiguity arises: "Which to run first?", but that can be easily achieved by slightly adjusting syntax of imports and specifying the priority/order of import. Something like:</p>
<pre><code>from foo import A priority 2
from foo import B priority 1
</code></pre>
<p>Please provide counter-arguments, if you see any.</p>

74,225,893 | <p>I have the below code that is creating the PriortyQueue structure using Dart. But since I cannot use heapify function inside the Constructor or factory constructor I cannot initialize PQ with an existing set of List. Can somebody guide me and show me how I can use heapify while creating PQ instance so I can initialize it with an existing List? Also If you have any other suggestions against doing something like this please also help me as well. thank you</p>
<pre><code>class PriorityQueue<T extends Comparable<T>> {
List<T?> _tree;
PriorityQueue._(List<T?> tree) : _tree = tree;
factory PriorityQueue([List<T>? array]) {
List<T?> newArray = [null, ...array ?? []];
// ignore: todo
//TODO: missing heapify
return PriorityQueue._(newArray);
}
void insert(T node) {
_tree.add(node);
_swim(_tree.length - 1);
}
T getTop() {
_swap(1, _tree.length - 1);
T top = _tree.removeLast() as T;
_sink(1);
return top;
}
List<T> _heapify(List<T> array) {
int sinkNodeIndex = (array.length - 1) ~/ 2;

74,225,914 | <p>I have two datasets, one for <code>migration inflow</code> to county <code>A</code> from other counties and other for <code>migration outflow</code> from county <code>A</code> to other counties. In order to combine the two data sets as:</p>
<pre><code>County State Inflow Outflow Year
</code></pre>
<p>The common column between the two datasets are <code>Origin_Place</code>, <code>Origin_StateName</code> and <code>Year</code> in <code>migration inflow</code> and <code>Dest_place</code>, <code>Dest_StateName</code> and <code>Year</code> in <code>migration outflow</code>.</p>
<p>Part of the problem is that the common columns have unequal number of rows.</p>
<p>How can combine the two into one dataset in such a way that I don't have to hardcode each and every common county name?</p>
<p>My original migration outflow data has 517 observations and migration inflow has 441, thus different number of counties in each dataset.</p>
<p>Dummy data:</p>
<pre><code># People moving out of county A to other counties
Origin_County_Name = c("A", "A", "A", "A", "A", "A", "A")
Origin_StateName = c("FL", "FL", "FL", "FL", "FL", "FL", "FL")
Individuals = c(223, 224, 2333, 4444, 5555, 6666, 7777)
Dest_place = c("B", "C", "D", "E", "F", "G", "H")
Dest_StateName = c("BB", "CC", "DD", "EE", "FF", "GG", "HH")
Year = c(2019, 2019, 2019, 2019, 2020, 2020, 2020)
Outflow_df = data.frame(Origin_County_Name, Origin_StateName, Individuals, Dest_place, Dest_StateName, Year)
# People moving in county A from other counties
Origin_Place = c("D", "E", "F")
Origin_StateName = c("DD", "EE", "FF")
Individuals = c(111, 8888, 9999)
Dest_County_Name = c("A", "A", "A")
Dest_StateName = c("FL", "FL", "FL")
Year = c(2019, 2019, 2020)

<p>but I found that the c++standard may not be able to derive βnew (ptr) T() == static_cast<T*>(ptr)β?
So conversely, βstatic_cast<T*>(ptr) == new (ptr) T()β cannot prove</p>
<pre><code>Trait<void>* operator->(){ return static_cast<Trait<void>*>(reinterpret_cast<void*>(_buffer)); }
</code></pre>
<p>Other attempts</p>
<p>a abstruct class can't be a union member(why?),and I can't use placement new to calculate offset at compile time, because Trait is an abstract class.</p>
<p>So does the standard specify the validity of static_cast<T*>(ptr) == new (ptr) T()?</p>

<p>The naΓ―ve way, in my mind, is to do something like this:</p>
<pre><code>for id in list(df['id'].unique()):
filtered_df = df[df['id'] == id]
</code></pre>
<p>But I believe this would be looping over the same data more times than is necessary, which is inefficient. Is there a fast way of doing this?</p>
<hr />
<h2>Update</h2>
<p>Did a little software drag racing. Here are the results:</p>
<pre><code>%%timeit
[df.loc[df.id.eq(i)] for i in df.id.unique()]
</code></pre>
<p>9.96 ms Β± 1.26 ms per loop (mean Β± std. dev. of 7 runs, 100 loops each)</p>
<pre><code>%%timeit
dflist=[]
dflist2=[]
for k,v in df.groupby(['id']):
var='id'+str(k)
dflist.append(var)
globals()[var] = v
dflist2.append(v)
</code></pre>
<p>1.28 ms Β± 92.2 Β΅s per loop (mean Β± std. dev. of 7 runs, 1,000 loops each)</p>
<pre><code>%%timeit
d = {id:df[df.id==id] for id in df.id.unique()}
</code></pre>
<p>9.19 ms Β± 885 Β΅s per loop (mean Β± std. dev. of 7 runs, 100 loops each)</p>
<p>Does anyone know why the second solution would be so much faster?</p>

74,226,092 | <p>Given an input tuple, the goal is to produce a dictionary with some pre-defined keys, e.g. in this case, we have an <code>add_header</code> lambda and use the unpacking inside when calling the function.</p>
<pre><code>>>> z = (2,1)
>>> add_header = lambda x, y: {"EVEN": x, "ODD": y}
>>> add_header(*z)
{'EVEN': 2, 'ODD': 1}
</code></pre>
<p>My question is, is there way where the unpacking doesn't need to done when calling the <code>add_header</code> function?</p>
<p>E.g. I can change avoid the lambda and do it in a normal function:</p>
<pre><code>>>> def add_header(input):
... x, y = input
... return {"EVEN": x, "ODD":y}
...
>>> z = (2, 1)
>>> add_header(z)
{'EVEN': 2, 'ODD': 1}
</code></pre>
<p>Or I could not use the unpacking and use the index of the tuple, i.e. the <code>z[0]</code> and <code>z[1]</code>:</p>
<pre><code>>>> z = (2, 1)
>>> add_header = lambda z: {"EVEN": z[0], "ODD": z[1]}
>>> add_header(z)
{'EVEN': 2, 'ODD': 1}
</code></pre>
<p>But is there some way to:</p>
<ul>
<li>Use the lambda</li>
<li>Don't explicitly use the indexing in the tuple</li>
<li>Don't unpack with <code>*</code> when calling the <code>add_header()</code> function but it's okay to be inside the lambda function.</li>
</ul>
<p>and still achieve the same <code>{'EVEN': 2, 'ODD': 1}</code> output given <code>z = (2,1)</code> input?</p>
<hr />
<p>I know this won't work but does something like this exist?</p>
<pre><code>z = (2,1)
add_header = lambda x, y from *x: {"EVEN": x, "ODD": y}
add_header(z)
</code></pre>

74,226,197 | <p>I have created an integer program in Python with GurobiPy for the 0-1 knapsack problem. However, I want to add a constraint that sais that if product x is added, then product y must also be added for some product couples.</p>
<p>My current model:
There are 2 warehouses, if products are stored in the main warehouse, the profit loss (due to delays) is 0. If the products are stored in the new warehouse, the profit loss is as presented in the dataframe. The objective is to minimize the profit loss</p>
<pre><code># Note: I run the program for the second warehouse because Xi returns values of 1 if placed in the warehouse
# so I can calculate the profit loss easier by just multiplying Xi by the profit loss
c = 1720 # total number of boxes minus capacity of the main warehouse
p = dfGurobi['profit'].tolist() # profit of each product
w = dfGurobi['boxes_required'].tolist() # weight of each product (=number of boxes required)
l = dfGurobi['profitLoss'].tolist() # profit loss of each product
n = len(p) # so determine the number of variables
assert n == len(w) # lengths of p and w should be the same
model = Model() # create a model
x = model.addVars(n, vtype=GRB.BINARY) # add variables
model.setObjective(quicksum(l[i] * x[i] for i in range(n)), GRB.MINIMIZE) # set objective to minimize the profit loss generated by placing products in the new warehouse
model.addConstr(quicksum(w[i] * x[i] for i in range(n)) >= c) # set constraint that the number of boxes in the new warehouse is at least 1720 so that the number of boxes in the main warehouse is at most 960
result = model.optimize() # optimize the model
print(result)
print("The optimal total profit loss is: %g" % model.objVal)
print(dfGurobi)
</code></pre>
<p>Also, I have a list of product couples indicating that if product 1 is placed in the main op new warehouse, the second product must also be placed in the same warehouse. This is the list:</p>

<p>How can I best add the product couples as a constraint?

My specific problem is: If product 1 is added to the warehouse (i.e. has a value of Xi = 1), then product 2 must also be added (i.e. have a value of Xi = 1). How can I do this?</p>

74,226,345 | <p>In my C++ application I configure some features in this way:</p>
<pre><code>#define LED_SIZE 113
#define SEGMENT_SIZE 3
const int LED_SEGMENTS[SEGMENT_SIZE] = {30, 70, 13};
</code></pre>
<p>I would like to check if the sum of the literal values are equal to <code>LED_SIZE</code>:</p>
<pre><code>30+70+13 = 113
</code></pre>
<p>I'm interested to do this at <strong>compile time</strong>, using a pre-processor directives.
If the sum is not correct it should not compile.</p>

74,226,359 | <p>So I have a list of index <code>close_index</code> I want to iterate over these specific index and update the column values.</p>
<pre><code>hhinc8,owncar,longitude,latitude,category
5,1,-82.99194508,40.04649963,LRLC
6,2,-82.99584706,40.03738548,LRHC
5,1,-82.99697268,40.02674247,LRLC
6,2,-82.99160441,40.03612997,LRHC
1,2,-82.994716,40.04691778,ERHC
2,1,-82.99793728,40.04385713,ERLC
3,2,-82.98986012,40.03789279,ERHC
.
.
.
</code></pre>
<p><strong>close_index =[1,3,4]</strong></p>
<p>now in my code I update the all the close_index's <code>hhinc8</code> like
<code>df.loc[close_index,'hhinc8']=2</code>
now I want to update the category of all the close_index by checking the <code>owncar</code> variable. If <code>owncar</code> is 1 category should be <code>LRLC</code> else it should be <code>LRHC</code>.</p>
<p>I thought the best way to do this is by looping over all the index in <strong>close_index</strong> and checking the <code>owncar</code> and updating the category.</p>
<p>But I am unable to figure out a way to <strong>loop over specific index</strong>.
As the dataset I have is very big, looping over the whole dataset is very inefficient.
If there is a better way to do this, Please let me know.</p>

UNWIND [197, 196, 19, 20, 191, 171, 3, 174, 194, 185] as unitID
MATCH (draft)-[:INCLUDES]->(u:Unit)

WITH count(DISTINCT u) as draftUnits
WITH COLLECT(draftUnits) as matchCounts
RETURN matchCounts

74,226,407 | <p>I have three folders on my desktop, each containing 2,000 .txt files, with files named numerically from 1.txt through 2,000.txt.
I want to use R to create data frames using the contents of the .txt files, where each line from the file is a row in the data frame. I want the columns of the data frame to be</p>
<p>Eg: Data Frame 1:</p>
<pre><code>| Folder 1 | Folder 2 | Folder 3 |
| -------- | -------- | --------
| contents | contents | contents of
| of 1.txt | of 1.txt | 1.txt
from folder from folder from folder
1. 2. 3.
Data Frame 2:
| Folder 1 | Folder 2 | Folder 3 |
| -------- | -------- | --------
| contents | contents | contents of
| of 2.txt | of 2.txt | 2.txt
from folder from folder from folder
1. 2. 3.
</code></pre>
<p>I was able to create a dataframe for one .txt from one folder using:</p>
<pre><code>setwd('/Users/name/Desktop/foldername')
txt_1 = readLines("1.txt")
df1 = data.frame(txt_1)
</code></pre>
<ol>
<li><p>How do I iterate through the folder and create separate data frames for each of the 2,000 txt files?</p>
</li>
<li><p>Additionally, how do I add the 2,000 corresponding txt files from folder 2 and folder 3 and columns 2 and 3 in each of the dataframes?</p>
</li>

<p>Thank you for the help!</p>

74,226,485 | <p>I'm working on a web scraper. Among the fields it scrapes there is a Description tag like this one, different for each product:</p>

<br>
REF.: V23T87C88EC
<br>
<br>
COMPOSIΓΓO:
<br>
90% Poliamida
</div>
</code></pre>
<p>I can get the content of the description tag without problems, but I also need to get the value of REF inside the description (V23T87C88EC for this example).</p>
<p>The problem is this description is always different for all products, HOWEVER there is ALWAYS a "REF.: XXXXXXXXX" substring in there.
The length of the REF id can change, and it can be anywhere in the string.
What's the best way to always get the REF id?</p>

74,226,542 | <p>I have an application in react native where i'm developing a search feature like Instagram.
It is like if user stop typing show him his query result.
my current approach is messing up redux. And sometimes it returns same element multiple times or sometime random elements which are irrelevant of that query.
right now. I'm calling search api immediately as use start typing in searchbar.</p>
<p>here is code below of my component.</p>
<pre><code>import { getSearchDataApi } from "../../api/search/search";
import { clearSearchData, setSearchData } from "../../redux/action/search";
const SearchScreen =(props)=>{
const [autoFocus,setAutoFocus] = useState(true)
const [keyWord,setKeyWord] = useState(null)
const [isLoading,setIsLoading] = useState(false)
const [isError,setIsError] = useState(false)
const [pageNumber,setPageNumber] = useState(1)
const [loadMore,setLoadMore] = useState(true)
const loadMoreDataFunc =()=>{
if (pageNumber <= props.totalSearchPage) {
setPageNumber(pageNumber+1)
}
else {
setLoadMore(false)
}
}
const searchData = async(keyWord)=>{
console.log(keyWord,pageNumber)
try {
setIsLoading(true)
var searchResponse = await getSearchDataApi(keyWord,pageNumber)
props.setSearchData(searchResponse.data)
setIsLoading(false)
}
catch (e) {
setIsError(true)
console.log("Error --- ", e.response.data.message)
showMessage({
message: e.response.data.message,
type: "danger",
});
}
}
return (
<View>
....
</View>
)
}
const mapStateToProps = (state)=>({
searchData: state.searchReducer.searchData,
totalSearchPage: state.searchReducer.totalSearchPage,
})
export default connect(mapStateToProps,{setSearchData,clearSearchData})(SearchScreen);
</code></pre>
<p>I will really every thankful to someone how can help me in fixing. Appreciation in advance!</p>
<p><em><strong>GOAL :</strong></em>
The goal that i want to achieve is when user stop typing then i call searchAPI with the keyword he/she entered in searchBar that's all.</p>
<p>I have also tried setTimeOut but that made things more worse.</p>

74,226,582 | <p>I have a templated class:</p>
<pre><code>template<Vector T>

<p>Now, I want to create a <code>concept DiagonalMatrix</code> for all of templated class versions. So:</p>
<pre><code> DiagonalMatrix<diagonal_matrix<std::vector<double>>> == true
DiagonalMatrix<diagonal_matrix<std::array<float, 4>>> == true
DiagonalMatrix<diagonal_matrix<std::span<int, 10>>> == true
DiagonalMatrix<diagonal_matrix<my::random_access_container_view<unsigned int>>> == true
DiagonalMatrix<other_matrix> == false
</code></pre>
<p>Keep in mind that <code>diagonal_matrix</code> has a subset of <code>other_matrix</code> functionality.</p>
<p>Is there a way to create a <code>concept DiagonalMatrix</code> which only accepts <code>struct diagonal_matrix<?></code> without tagging the struct with a <code>static constexpr bool I_am_a_diagonal_matrix = true;</code>?. I don't care for implementations other than <code>struct diagonal_matrix<?></code>.</p>

74,226,625 | <p>If a function <code>f: (X => Y) | undefined</code> is possibly undefined, and <code>x: X</code> is defined, then we can use optional-chaining operator <code>?.</code> to apply <code>f</code> to <code>x</code>:</p>
<pre class="lang-js prettyprint-override"><code>f?.(x) // ok, no problem if `f` is undefined
</code></pre>
<p>But when <code>f: X => Y</code> is defined and <code>x: X | undefined</code> is possibly undefined, there does not seem to be any syntax to "map" the <code>f</code> over the "optional" <code>x</code>:</p>
<pre><code>f(?.x) // not valid syntax; Unclear what to do when `x` is undefined
</code></pre>
<p>I could try to implement <code>pipeTo</code> to swap the order of <code>f</code> and <code>x</code>, and then make it work with <code>?.</code> again, as follows:</p>
<pre class="lang-js prettyprint-override"><code>function opt<X>(x: X | undefined): { pipeTo<Y>(f: (a: X) => Y): Y } | undefined {
return typeof x === 'undefined' ? undefined : {
pipeTo<Y>(f: (a: X) => Y): Y {
return f(x)
}
}
}
</code></pre>
<p>which I could then use as <code>opt(x)?.pipeTo(f)</code>, for example:</p>
<pre><code>function square(n: number): number { return n * n }
for (const x of [42, undefined, 58]) {
console.log(opt(x)?.pipeTo(square))
}
</code></pre>
<p>Is there any less cumbersome standard solution for applying a certainly existing <code>f</code> to a possibly undefined <code>x</code>?</p>
<hr />
<p>Clarification: <em>"cumbersome"</em> := anything that forces me to write down the subexpression <code>x</code> twice, or to clutter the scope with meaningless helper-variables.</p>

74,226,657 | <p>When I use the <code><Link></code> tag in NextJs to navigate between pages it doesn't rerun my scripts after changing pages. It only runs the scripts after the first page load or when I press reload. When using plain <code><a></code> tags instead, it works fine because the page reloads after each navigation. As far as I can tell this happens because the <code><Link></code> tag makes it a Single-Page Application and doesn't refresh the page when navigating between pages.</p>
<p>I would greatly appreciate anyway to have it rerun the scripts when navigating between pages or to have it refresh the page without using just plain <code><a></code> tags and losing the Single-Page Application functionality.</p>
<p>This code doesn't refresh the page</p>
<pre><code> <Link href="/page1">
<a>Page 1</a>
</Link>
<Link href="/page2">
<a>Page 2 </a>
</Link>
</code></pre>
<p>This code does refresh the page</p>
<pre><code> <a href="/page1">Page 1</a>
<a href="/page2">Page 2 </a>

onReady={() => {
console.log("Ready")

/>
)
}
</code></pre>
<p>One thing I've noticed is that the above <code>onReady</code> function fires each time I change pages. Maybe someone knows how to run the <code>myScript.js</code> from the <code>onReady</code>.</p>

74,226,662 | <p>I am trying to write a Python script that more or less mimics the New York Times game Spelling Bee (if you've played it). I have a code that prints out all the words from a list of letters, but I want to be able to repeat letters. For example, <code>fsde</code> produces nothing, but I want <code>feed</code> to be part of the results. Another example is the letters <code>etmxr</code> to produce <code>extreme</code> (Basically any letter can be repeated as many times as possible if the language has a word that allows it). Here is the code I have using <code>itertools</code> so far:</p>
<pre><code>import itertools
import enchant
d = enchant.Dict("en_US")
answer = []
user_input = input("Input letters here: ")
center = input("Input center letter here: ")
while len(center)>1 or center not in user_input:
center = input("Either you entered a letter not in the first input, or you entered more than one letter. Try again: ")
letters = [x.lower() for x in user_input]
words = d
for t in range(4, len(user_input)):
for m in itertools.permutations(user_input, t):
a = "".join(m)
if center in a:
if d.check(a):
answer.append(a)
print(answer)
</code></pre>
<p>Right now you just enter letters and get all the words from them, and that's all I want right now. If there's any way to get a double or triple letter I would really appreciate it.</p>
<p>I have scoured google and stackoverflow to no avail, I got the original code from a video but it doesn't have repeated letters and even though I now fully understand <code>permutations</code> I can't get multiple letters haha. I've tried <code>product</code> and <code>combination</code> with no luck, and a lot more but I think it's just a methodology thing I have wrong.</p>

74,226,681 | <p>I have a class that wraps an array. It inherits from an abstract base class defining one <code>virtual constexpr</code> method for the function-call operator. In the child class, I override said method and access the internal array:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <cstddef>
#include <array>
#include <initializer_list>
template <typename T, std::size_t N>
class ContainerBase {
public:
virtual constexpr const T& operator()(std::size_t i) const = 0;
};
template <typename T, std::size_t N>
class Container : public ContainerBase<T, N> {
public:
constexpr Container(std::initializer_list<T> data) {
std::copy(data.begin(), data.end(), _items.begin());
}
constexpr const T& operator()(std::size_t i) const override {
return _items[i];
}
private:
std::array<T, N> _items;
};
int main () {
constexpr Container<int, 3> C = {2, -91, 7};
constexpr int F = C(1);
static_assert(F == -91);
}
</code></pre>
<p>Here is the <a href="https://godbolt.org/z/roe36E7P4" rel="nofollow noreferrer">godbolt link</a>.</p>
<p>To the best of my understanding, this is all legal code in C++20, which allows <code>virtual constexpr</code>. G++ 10.3 and Clang 12 both accept this as valid code, however MSVC 19.33 does not accept it, claiming that variable <code>F</code> is not a constant expression:</p>
<pre><code>msvc_buggy_constexpr.cpp(29,21): error C2131: expression did not evaluate to a constant
msvc_buggy_constexpr.cpp(21,16): message : a non-constant (sub-)expression was encountered
msvc_buggy_constexpr.cpp(31,5): error C2131: expression did not evaluate to a constant
msvc_buggy_constexpr.cpp(21,16): message : a non-constant (sub-)expression was encountered
</code></pre>
<p>What gives? This looks like a compiler bug in MSVC to me. I would investigate further but MSVC on godbolt.org seems to be down right now.</p>
<p>I should add, the issue only presents itself when the function call operator method is <code>virtual</code> βwhen it is not, the issue does not occur.</p>
<p>Can anyone advise?</p>

74,226,682 | <p>I have a bunch of files names as such:</p>
<pre><code>Belinda Carlisle - Mad About You-Xmdtjwmr9zq.mp4
Air Supply - All Out of Love-Jwdzeumnrmi.mp4
Blue Savannah Song - Erasure-Wxoutwk8jv8.mp4
Breathe - How Can I Fall (1988)-Pwz4erdjzra.mp4
</code></pre>
<p>I would like to be able to trim out the suffix of random characters. I got some help with formulating a regex, and I slapped together a two-liner in PowerShell, and it works. The only caveat is that I have to first filter by the regex before piping it to 'rename-item', otherwise, it adds two extensions to the filename like
Belinda Carlisle -Mad About You.mp4.mp4 for the filenames that are 'clean' - aka without the extraneous suffix.</p>
<p>Can this be done another way so that I don't have to filter by matching regex and achieve the same thing? Not being nitpicky, just curious.</p>
<p>Here's the expression I cobbled together.</p>
<pre><code>Get-ChildItem $targetpath -file |
where-object {$_.name -match "-[a-z\d]+(?=\.[^.]+$)"} |
ForEach-Object {
Rename-Item -Path $_.FullName -NewName ('{0}{1}' -f ($_.Name -replace "-[a-z\d]+(?=\.[^.]+$).*","$1"), $_.Extension )
}

<p><strong>Note</strong>: if I put technician with value "battery" on the top then it will only work remaining 2 will not work.</p>
<p>My <strong>ultimate goal</strong> is make all the technicians work so I can put condition on them.</p>
<p><em>For example</em> if My agent <strong>customer</strong> have parameter called "battery" is true then technician with value "battery" will work on it and on remaining customers remaining 2 technicians work.</p>
<p>Something like that:</p>
<pre><code>if (agent.batteryProb == true){
((technician)unit).problemsSolved.equals("battery");}
else{
((technician)unit).problemsSolved.equals("batter");
((technician)unit).problemsSolved.equals("batte");}

74,226,691 | <p>I want to use different IWebDrivers For My Method. For that I use different public IWebDrivers. So far no problem. However I would like to use a variable whenever I for example want to search for a specific element.</p>
<p>For Illustration: <code>driver.Navigate.GoToUrl("https://www.google.com"); </code> So, how would I know use a not yet defined variable? In my method I will use an if statement in connection with an else if statement, so depending on which if statement is used, a specific driver should be used.</p>
<p>For Illustration: <code>if (...) a = driver1 else if (...) a = driver2</code>. Since the driver would only defined whenever one of the if-statements or if-else statements has been initialized, it tells me that I can't use .Navigate with a. Is there a way to solve this? Otherwise I would have a lot of duplicate code</p>

74,226,704 | <p>Good afternoon,
Here is my problem: I have a Pandas dataframe that looks like it:</p>
<pre><code>Birth_Year Name
1964 [X, Y]
1965 [A, B]
1964 [F, G, H]
</code></pre>
<p>I need to transform it to the following:</p>
<pre><code>Birth_Year Name_1 Name_2 Name_3
1964 X Y
1965 A B
1964 F G H
</code></pre>
<p>So I need to get the max length of lists in column 'Name', create the datafame with column for each item in the list, and populate it with the values from the list.</p>
<p>Would really appreciate an advice on how to handle this problem.</p>
<p>I have no good solution for it.</p>

74,226,724 | <p>I am currently utilizing a hold block to restrict agent of type <code>Patient</code> passing to a seize block. Upstream in the model, <code>Patient</code> are assigned only 1 unit of <code>Doctor</code> that it will interact with downstream in the model every time is seizes <code>Doctor</code> (This is shown in photo one, in the <code>Doctor</code> resource pool).</p>
<p>The problem is that I would like to access this particular unit of <code>Doctors</code> in a function that I have, in order to check if that specific unit of <code>Doctor</code> is idle. Photo 2 is the function im using at the moment, and I would like to add this solution as the third condition in the if statements. It already checks if an Surgeon is available, but I need to add a check to see if their specific <code>Doctor</code> is available.</p>

</div>
<p>So I want to write a SQL query that allows me to result with the records associated with payIDs 90,91,94 and 95 because I want records associated with multiple paydates of the same category within the same userclass.</p>
<p>--
So far I can get the entirety of the queried results as show in the example above</p>
<p>With my structure being something like:</p>
<pre><code>
SELECT
p.payID,
p.userclass,
pc.category,
p.paydate
FROM
pay p
INNER JOIN paycategory pc
ON p.categoryID = pc.categoryID
</code></pre>
<p>Which shows everything but not filtered down to the 4 records I want to be output.<br />
i.e</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>PayID</th>
<th>userclass</th>
<th>category</th>
<th>paydate</th>
</tr>
</thead>
<tbody>
<tr>
<td>90</td>
<td>111</td>
<td>7</td>
<td>1/1/2022</td>
</tr>
<tr>
<td>91</td>
<td>111</td>
<td>7</td>
<td>3/1/2022</td>
</tr>
<tr>
<td>94</td>
<td>444</td>
<td>9</td>
<td>3/15/2022</td>
</tr>
<tr>
<td>95</td>
<td>444</td>
<td>9</td>
<td>4/1/2022</td>
</tr>
</tbody>
</table>
</div>
<p>I think I need to use the count function or something along that line but I'm having trouble understanding it.</p>
