<p>I have a page with a table and dynamic filters in it. When a filter changes, I need to redirect to the current page with a new or updated query parameter. For example, if I'm in the <code>/users</code> route and the name "John" is being searched, I need to redirect to <code>/users?name=john</code>. If I want to see all Johns with application role, I need to redirect to <code>/users?name=john&hasRole=true</code> and so on. The reason for this is that a search result must be reproducible by sharing the URL.</p>
<p>I need all query parameters as a <code>Dictionary<string, string></code>. How can I bind all query parameters to a <code>Dictionary<string, string></code> in Blazor WASM?</p>

<p>Working in Google AppsScript, specifically for an add-on, and I'm defining the SHEET_NAME as a const. Specifically:</p>
<pre><code>const SHEET_NAME="Values"
</code></pre>
<p>Since Google Sheets has a default name of "Sheet1" for all worksheets can I also make SHEET_NAME be associated to either "Values" or "Sheet1"?</p>
<p>Basically, if someone doesn't choose to name their file "Values" then the variable will still know to run SHEET_NAME without breaking.</p>
<p>Right now I have a function that is trying to use the SHEET_NAME variable, but again, trying to see if I can have it look for either "Values" or "Sheet1"</p>
<p>Is something like <code>const SHEET_NAME="Values" OR "Sheet1"</code> doable?</p>

<p>pthread_kill() funktion terminates my program every time I launch it after a creation of a thread and try to send a SIGALRM signal. By the way, it works if I add a sleep() function before pthread_kill(). Then I add sleep() function in thread, because it terminates earlier then sending a signal.</p>
<pre><code>void* funkcja_watku(){
struct sigaction new_action = {.sa_handler = obsluga};
sigaction(SIGALRM, &new_action, NULL);
sleep(2);
return 0;
}
int main(int argc, const char * argv[]) {
pthread_t watek_id;
//tworze watek
if(pthread_create(&watek_id, NULL, &funkcja_watku, NULL))
printf("Watek nie zostal utworzony\n");
sleep(1);
//wysylam sygnal
if(pthread_kill(watek_id, SIGALRM))
printf("Sygnal nie zostal wyslany\n");
//usuwam watek
if(pthread_join(watek_id, NULL))
printf("Watek nie zostal usuniety\n");
return 0;
}
</code></pre>
<p>I added the sleep function, but I dont think that It is the good way</p>

<p>I am supposed to write a program that processes a sequence of 100 positive numbers. The program should have 3 different functions, which could be chosen from a menu.</p>
<ol>
<li><p>Generate a number sequence with a random generator and print the numbers on the screen. The numbers generated should be in the range 0 ≤ n ≤ 900</p>
</li>
<li><p>I have to sort the sequence with bubble sort and then the numbers must be printed and I cannot use built-in sorting functions, such as qsort.</p>
</li>
<li><p>Quit program.
The 1 and 2 must be in own functions.
Lasly every time the program prints out the number, it should be printed as a table with ten rows and ten columns. Choice two can not be made unless choice one has been chosen.</p>
</li>
</ol>
<pre><code>#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#define SIZE 100
#define N 10
#define INVALID 0
#define VALID 1
void randomNum() {
//random number gen
int num[SIZE] = {0};
int i = 0;
srand(time(NULL));
for(i = 0; i < SIZE; i++) {
num[i] = rand() % 901;
}
for(i = 0; i < SIZE; i++) {
printf("%4d", num[i]);
if(i % 10 == 9)
printf("\n");
}
}
void sort() {
//sort of the generated number sequence
int num[SIZE] = {0};
int i = 0;
int j = 0;
int temp = 0;
for (int i = 0 ; i < SIZE; i++)
{
for (int j = 0; j < SIZE - 1; j++)
{
if (num[j] > num[j+1])
{
temp = num[j];
num[j] = num[j+1];
num[j+1] = temp;
}
}
}
for(i = 0; i < SIZE; i++) {
printf("%4d", num[i]);
if(i % 10 == 9)
printf("\n");
}
}
int main() {
randomNum();
printf("\n");
sort();
return 0;
}
</code></pre>
<p>I have figured out the solutions for how to generate a sequene and sort it and it works correct when all the code are in main() , however, when I put in in own functions above the main() it does not work. I'm stuck and don't know how to move forward. When i run the program it generates a random sequence but then the sorting function just prints out 100 zeros.</p>

<p>I want to copy specific content from the page, rather than the HTML itself.
And the execCommand method, is deprecated, I tried with useRef(), but no progress</p>
<p>How i solve this?</p>
<pre><code> const div = useRef(null);
const [copySuccess, setCopySuccess] = useState(false);
const copyToClipboard = () => {
const html = div.current.innerHTML.trim();
navigator.clipboard.writeText(html)
setCopySuccess(true);
};
<div>
{user.name && (
<button
type="submit"
style={{
margin-top: '30px',
margin-bottom: '10px',
height: '45px',
width: '85px',
background-color: '#1d71a5',
color: '#fff',
border: 'none',
border-radius: '5px',
font-size: '16px',
cursor: 'pointer',
}}
onClick={copyToClipboard}
>
Copy
</button>
)}
{copySuccess && (
<div style={{ color: 'green' }}> ✔︎ Copy with Success! </div>
)}
</div>
</code></pre>
<p>I want to copy the signature email content</p>
<p>Refrence: <a href="https://vdt-email-signature.vercel.app" rel="nofollow noreferrer">https://vdt-email-signature.vercel.app</a></p>
<p>I tried to use the hook useRef, i tried to use this method :</p>
<pre><code>const copyDivToClipboard = () => {
const range = document.createRange()
const selectedDiv = document.getElementById('generated-div')
range?.selectNode(selectedDiv as Node)
window?.getSelection()?.removeAllRanges() // clear current selection
window?.getSelection()?.addRange(range) // to select text
document.execCommand('copy')
window?.getSelection()?.removeAllRanges() // to deselect
alert('Message copied to clipboard!')
}
</code></pre>
<p>But is a deprecated method.</p>
<p>And so far I have no progress.</p>

<p>I have a 2D gaussian function <code>f(x,y)</code>. I know the values <code>x₀</code> and <code>y₀</code> at which the peak <code>g₀</code> of the function occurs. But then I want to find <code>xₑ</code> and <code>yₑ</code> values at which <code>f(xₑ, yₑ) = g₀ / e¹</code>. I know there are multiple solutions to this, but at least one is sufficient.</p>
<p>So far I have</p>
<pre class="lang-py prettyprint-override"><code>def f(x, y, g0,x0,y0,sigma_x,sigma_y,offset):
return offset + g0* np.exp(-(((x-x0)**(2)/(2*sigma_x**(2))) + ((y-y0)**(2)/(2*sigma_y**(2)))))
</code></pre>
<p><em>All variables taken as parameters are known</em> as they were extracted from a curve fit.</p>
<p>I understand that taking the derivative in <code>x</code> and setting <code>f() = 0</code> and similarly in <code>y</code>, gives a solvable linear system for <code>(x,y)</code>, but this seems like overkill to manually implement, there must be some library or tool out there that can do what I am trying to achieve?</p>

<p>I want to send ether from one walet to another…what technique to use and what is the safest method to do so?
wallet A(msg.sender)=10ether
wallet B=10ether
with the help of smart contract send 'x' ether from A to B.</p>
<p>I tried
where 'x' is the varaible ether at different times.
=>payable().transfer(msg.value);
here i am able to send ether in remix ide where i can provide the msg.value...i want to implement that it is able to change msg.value according to the value of x.</p>

<p>First, apologies if this sounds too basic. I have the following semi-structured data in text format, I need to parse these into a structured format:
example:</p>
<pre><code>Name
Alex
Address
14 high street
London
Color
blue
red
Name
Bob
Color
black
</code></pre>
<p>**Note that Alex has two colors, while Bob does not have an address. **</p>
<p>I want something that looks like this:</p>
<p><a href="https://i.stack.imgur.com/RHt45.png" rel="nofollow noreferrer">example output</a></p>
<p>I think the right way is using regular expressions, but I'm struggling to split the text properly since some fields may be missing. What's a proper clean way to do this?</p>
<pre><code>text='Name\nAlex\n\nAddress\n14 high street\nLondon\n\nColor\nblue\nred\n\nName\nBob\nColor\nblack'
profiles=re.split('(Name\n)', text, flags=re.IGNORECASE)
for profile in profiles:
#get name
name=re.split('(Name\n)|(Address\n)|(Color\n)', profile.strip(), flags=re.IGNORECASE)[0]
print(name)
#get address
#get color
</code></pre>

<p>I have a dataframe that has duplicates based on their identifying ID, but some of the columns are different. I'd like to keep the rows (or the duplicates) that have the extra bit of info. The structure of the df is as such.</p>
<pre><code>id <- c("3235453", "3235453", "21354315", "21354315", "2121421")
Plan_name<- c("angers", "strasbourg", "Benzema", "angers", "montpellier")
service_line<- c("", "AMRS", "", "Therapy", "")
treatment<-c("", "MH", "", "MH", "")
df <- data.frame (id, Plan_name, treatment, service_line)
</code></pre>
<p>As you can see, the ID row has duplicates, but I'd like to keep the second duplicate where there is more info in <code>treatment</code> and <code>service_line</code>.</p>
<p>I have tried using</p>
<pre><code>df[duplicated(df[,c(1,3)]),]
</code></pre>
<p>but it doesn't work as an empty df is returned. Any suggestions?</p>

<p>I have a dimensional array and I would like to order it by expiryDate ascending and keep the ones with the null value last</p>
<p>here is my array:</p>
<pre><code>$lessons = [
[
"expiryDate" => Null
],
[
"expiryDate" => "2023-11-27"
],
[
"expiryDate" => "2022-11-27"
]
];
</code></pre>
<p>What I tried :</p>
<pre><code>$price = array_column($lessons, 'expiryDate');
array_multisort($price, SORT_ASC, $lessons);
</code></pre>
<p>Its working fine, but I don't know how I can move the ones with expiryDate last</p>
<p>The expected Result :</p>
<pre><code>$lessons = [
[
"expiryDate" => "2022-11-27"
],
[
"expiryDate" => "2023-11-27"
],
[
"expiryDate" => Null

<p>I need to make a form with 2 input fields. When you press submit it should take you to a new page and display the input data.</p>
<p>This is my html code</p>

</head>
<body>
<form id="form" action="./Success.html">
<h1>Movie survey</h1>
<p>Thank you for participating in the film festival!</p>
<p>Please fill out this short survey so we can record your feedback</p>
<div>
<label for="film">What film did you watch?</label>

<div>
<input type="text" id="film" name="film" required />

<div><button class="submit">Submit</button></div>
</form>

<p>This is my js code</p>
<pre><code>const formEl = document.querySelector("#form");
formEl.addEventListener("submit", (event) => {
event.preventDefault();
const formData = new FormData(formEl);
fetch("https://reqres.in/api/form", {

})
.then((response) => {

})
.catch((error) => {
console.error(error);
});
});
</code></pre>
<p>I have a second html page called Success.html which I want to display tha data given in the form. I need to make a mock API so I tried using reqres.</p>
<p>This is my Success.html page</p>
<pre><code><!DOCTYPE html>

<p>I create different <code>numpy</code> arrays as follows:</p>
<pre class="lang-py prettyprint-override"><code>import numpy as np
a = np.array([[1,2,3],[1,2,3]]) # 2d array of integers
b = np.array([[1,2,3],[1,2,5.0]]) # 2d array of floats
c = np.array([1,2,3,4,5,6,7,8,9]) # 1d array of integers
d = np.array([10,20,30]) # different 1d array of integers
# python buffer object pointing to the start of the arrays data.
print(a.data)
print(b.data)
print(c.data)
print(d.data)
</code></pre>
<p>According to the numpy docs i expect to get a "<em>python buffer object pointing to the start of the arrays data</em>". Here is the official doc (from the numpy website): <a href="https://numpy.org/doc/stable/reference/generated/numpy.ndarray.data.html" rel="nofollow noreferrer">https://numpy.org/doc/stable/reference/generated/numpy.ndarray.data.html</a></p>
<p>So i would <strong>expect a different memory address</strong> for each array.</p>
<p>but i get this:</p>
<pre><code><memory at 0x000001EAE8B7CAD0>
<memory at 0x000001EAE8B7CAD0>
<memory at 0x000001EAE98E8A00>
<memory at 0x000001EAE98E8A00>
</code></pre>
<ul>
<li>The first two have the same memory buffer object pointer.</li>
<li>And the second two have the same memory buffer object pointer.</li>
</ul>
<p>Is <code>numpy</code> inferring the memory buffer object pointer based on the dimension of the array or if not, what is the rule that generates similar pointer addresses ?</p>

<p>I faced a problem with React CSS. My server is picking up, but my CSS properties are not working on my component. How can I fix this problem? I tried many ways to figure it out but I didn't get a good response.</p>
<p><code>App.js</code> file codes:</p>
<pre><code>import styles from "./App.module.css";
import { ReactDOM } from "react";
import { useEffect, useState } from "react";
import { init, subscribe } from "./socketApi";
import Palatte from "./components/Palatte";
function App() {
const [activeColor, setActiveColor] = useState("#282c34");
useEffect(() => {
init();
subscribe((color) => {
setActiveColor(color);
});
}, []);
return (
<div className="App" style={{ backgroundColor: activeColor }}>
<h1>{activeColor}</h1>
<Palatte activeColor={activeColor} />
</div>
);
}
export default App;
</code></pre>
<p>CSS file codes:</p>
<pre><code>.App {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
flex-direction: column;
}
.palette {
display: flex;
flex-direction: column;
margin-top: 40px;
}
.palette button {
margin-top: 10px;
}
</code></pre>
<p>I tried many ways to fix it but I didn't get a solution.</p>

<p>I am learning Java and I have some difficulties with the package mechanism. I have different classes in a package. I compiled it right but when I execute the Main file I have a different behavior. <em>Music3</em> is the file where is the main method.</p>
<pre><code>andrea@andrea:~/Documenti/java$ java -Xdiag -cp class/ source/Music3

<p>As you can see I have the right output when I execute Music3.java. What is wrong?</p>

<p>I am currently trying to finish a assignment but I am confused on how to fix this error. I am creating a program that will analyzes grades from a file and should calculate the
average score for each distinct section (given). I receive the error for</p>

else:

<p>I have 2 dataframes with same columns and indexes.</p>
<pre><code> a a
1 [] 1 [5,2,7]
2 [1,2,3] 2 [1,2,3,4]
3 [7] 3 [7,5]
</code></pre>
<p>I want to merge them using condition, when length of list is <=1 then take value and add it to 1st data frame, else left old value.</p>
<p>So after that result is:</p>
<pre><code> a
1 [5,2,7]
2 [1,2,3]
3 [7,5]
</code></pre>
<p>What is the best way to do this?</p>

echo "################################################################"
echo
if ! location=$(type -p "htop"); then

<code>location=$(type -p "htop");</code>
I need a clear explanation about this.</p>

<p>I have a JSON file. While the original file is quite large, I reduced to a much smaller reproducible example for the purposes of this question (I still get the same error no matter what size):</p>

"string_list_data": [

<p>I am attempting to convert it into a dataframe in R, which contains the values for <code>href</code>, <code>value</code>, and the <code>timestamp</code> variables:</p>
<p><a href="https://i.stack.imgur.com/Csgk9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Csgk9.png" alt="enter image description here" /></a></p>
<p>But when I run the following, which I pulled from another SO answer about converting JSON to R:</p>
<pre><code>library("rjson")
result <- fromJSON(file = "test_file.json")
json_data_frame <- as.data.frame(result)
</code></pre>
<p>I get met with this error about differing rows.</p>
<pre><code>Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 1, 0
</code></pre>
<p>How can I get what I have into the desired DF format?</p>

<p>I made some changes on my branch, I fetched changes and ran 'git merge'. I then made more local changes and wanted to amend my commit: git commit --amend.
But when trying to push I received that error:</p>
<pre><code>remote: error: GH006: Protected branch update failed for refs/heads/v1.
remote: error: This branch must not contain merge commits.
! [remote rejected] v1 -> v1 (protected branch hook declined)
error: failed to push some refs to xxx
</code></pre>
<p>I tried to abort but:</p>
<pre><code>git merge --abort
fatal: There is no merge to abort (MERGE_HEAD missing).
</code></pre>
<p>How can I cancel the merge commit without losing my local changes?</p>

<p>I need to create a code using loops to ask for user input on certain values.
Of those values I need to ask the user if they want me to find the smallest or largest number or just end the program. If the number -1000 is entered in the program the program ends. Basically how do I link my menu of options to a the actual actions per option.Here's what I have so far.</p>
<pre><code>numbersEntered = []
lengthNumbers = int(input("Please enter the length of your list/array:"))
print("Please enter your numbers individually:")
for x in range(lengthNumbers):
data=int(input())
numbersEntered.append(data)
def menu():
print("[A] Smallest")
print("[B] Largest")
print("[C] Quit")
menu()
Options=float(input(f"Please select either option A,B,or C:"))
optionA = min(numbersEntered)
optionB = max(numbersEntered)
optionC = quit
while numbersEntered != C:
if numbersEntered == A:
print("The smallest number is:", min(numbersEntered))
elif numbersEntered == B:
print("The largest number is:", max(numbersEntered) )
elif numbersEntered ==-1000:
print("Quit")
</code></pre>
<p>I tried a while loop to connect the menu to said action but that did not work and idk why. I am a beginner programer so I'm very new to this stuff.</p>

<p>I am creating a security group that has some standard ingress rules. I also want to add additional ingress rules based on a variable.</p>
<pre><code>variable "additional_ingress" {
type = list(object({
protocol = string
from_port = string
to_port = string
cidr_blocks = list(string)
}))
default = []
}
resource "aws_security_group" "ec2" {
name = "my-sg"
description = "SG for ec2"
vpc_id = data.aws_vpc.this.id
egress {
to_port = 0
from_port = 0
protocol = "-1"
cidr_blocks = ["0.0.0.0/0"]
}
ingress {
protocol = "tcp"
from_port = 22
to_port = 22
cidr_blocks = ["10.0.0.0/8"]
}
# rdp
ingress {
protocol = "tcp"
from_port = 3389
to_port = 3389
cidr_blocks = ["10.0.0.0/8"]
}
# additional ingress rules
ingress {
for_each = var.additional_ingress
protocol = each.value.protocol
from_port = each.value.from_port
to_port = each.value.to_port
cidr_blocks = each.value.cidr_blocks
}
}
</code></pre>
<p>I am getting error</p>
<blockquote>
<p>A reference to "each.value" has been used in a context in which it
unavailable, such as when the configuration no longer contains the
value in its "for_each" expression. │ Remove this reference to
each.value in your configuration to work around this error.</p>
</blockquote>
<p>How do I add ingress rules based on variable</p>

<p>I have a vector of numbers that contain some gaps. For example,</p>
<pre><code>vec <- c(3,1,7,3,5,7)
</code></pre>
<p>So, there are 4 different values and I would like to transform it into a vector of values (without gaps) indicating the order of the entry while respecting the same position. So, in this case, I would like to obtain</p>
<pre><code>2 1 4 2 3 4
</code></pre>
<p>Indicating a sequence of between 1 and 4 and showing the orders in the original vector <code>vec</code>.</p>

<p>I have the following three dictionaries within a list like so:</p>
<pre><code>dict1 = {'key1':'x', 'key2':['one', 'two', 'three']}
dict2 = {'key1':'x', 'key2':['four', 'five', 'six']}
dict3 = {'key1':'y', 'key2':['one', 'two', 'three']}
list = [dict1, dict2, dict3]
</code></pre>
<p>I'd like to merge the dictionaries that have the same value for key1 into a single dictionary with merged values (lists in this case) for key2 like so:</p>
<pre><code>new_dict = {'key1':'x', 'key2':['one', 'two', 'three', 'four', 'five', 'six']}
list = [new_dict, dict3]
</code></pre>
<p>I've come up with a very brutish solution riddled with hard codes and loops. I'd like to employ some higher-order functions but I'm new to those.</p>

<p><strong>I have the following query:</strong> that is trying to get pt_ids that have certain diagnosis codes OR certain outcome_codes. I have accounted for these conditions by including the specific codes I'd like in the WHERE clause. However, I would like to know if I can also do this using in INNER JOIN.</p>
<pre><code>SELECT DISTINCT
pt_id
FROM #df
WHERE flag <> 1
AND (diagnosis IN
(
SELECT Code
FROM #df_codes
WHERE code_id = '20'
)
OR outcome_code IN
(
SELECT Code
FROM #df_codes
WHERE code_id = '25'
));
</code></pre>
<p>The above code is taking quite a while to run and I am wondering if writing it in the following way 1) is appropriate/viable and 2) will leader to a faster run time. I am essentially trying to join #df with #df_codes on either Code = diagnosis OR code = outcome_code</p>
<p><strong>My Solution</strong></p>
<pre><code>SELECT DISTINCT
pt_id
FROM #df a
JOIN (select * from #df_codes where code_id = '20')b ON a.diagnosis = b.Code OR
(select * from #df_codes where code_id = '25')c ON a.outcome_code = c.Code
WHERE flag <> 1
</code></pre>

<p>I am new to <code>bash</code>. I have a question about determining if all characters of one string occur within another string. For example, if the variables are:</p>
<pre class="lang-bash prettyprint-override"><code>var_1="abcdefg"
var_2="bcg"
</code></pre>
<p>Then I want to write an <code>if</code> statement of the form:</p>
<pre class="lang-bash prettyprint-override"><code>if [all characters of var_2 occur within var_1]
then
echo "All characters of var_2 occur in var_1."
else
echo "Not all characters of var_2 occur in var_1."
fi
</code></pre>
<p>In this example, the output should be <code>All characters of var_2 occur in var_1.</code> What would go in the <code>if</code> statement here?</p>
<p>This is what I tried:</p>
<pre class="lang-bash prettyprint-override"><code>if [[ $var_1 == *$var_2* ]]
</code></pre>
<p>... but I think this is only determines if <code>var_2</code> is a substring of <code>var_1</code>. What I want is to determine if the characters of <code>var_2</code> occur within <code>var_1</code> in no particular order.</p>

<p>I have a Shiny app that takes a dataset and filters it through several user inputs. To do this, I use selectizeInput functions where the user can select one or many options from a list and then these selections are run through reactive statements to get the desired final dataset. I've noticed recently that this no longer works in one of the places I have the app hosted; this app was built and deployed with Shiny 1.6.0 and it's still working in that location, but it isn't working in another spot that has Shiny 1.7.3. I'm wondering if this may be an issue with newer versions of Shiny. Here is an example where multiple selections causes the resulting table to not populate:</p>
<pre><code>library(shiny)
library(dplyr)
data <- mtcars
ui <- fluidPage(
fluidRow(
column(width = 4, wellPanel(
selectizeInput("carb", "carb:", c("All", sort(unique(data$carb))),
selected = "All", multiple = TRUE,
options = list('plugins' = list('remove_button'),
'create' = TRUE, 'persist' = FALSE)))),
column(width = 8, wellPanel(tableOutput("table")))
)
)
server <- function(input,output,session){
process <- reactive({
req(input$carb) # require some input
if(input$carb == "All"){data} #pass entire dataset if selected
else(data %>% dplyr::filter(carb %in% input$carb))}) # will not work with > 1 selected
output$table <- renderTable({process()})
}
shinyApp(ui = ui, server = server)
</code></pre>
<p>Selecting just one value allows everything to work fine, but there's an error about the condition having length > 1 if multiple values are selected. Previously when this worked, I was able to select something like 1,2, and 4 for the carb variable and the resulting table would show all rows with one of those three values. I know the input is getting passed on to the argument by adding a renderTable statement into the server:</p>
<pre><code>output$test <- renderTable({as.data.frame(input$carb)})
</code></pre>
<p>However, this isn't working when I'm trying to filter the full dataset. I can run everything when selectizeInput(multiple = FALSE), but ideally it should be equal to TRUE so the user has more functionality.</p>

<p>I have a dataframe in the following where Day_1, Day_2, Day_3 are the number of impressions in the past 3 days.</p>
<pre><code>df = pd.DataFrame({'Day_1': [2, 4, 8, 0],
'Day_2': [2, 0, 0, 0],
'Day_3': [1, 1, 0, 0],
index=['user1', 'user2', 'user3', 'user4'])
df
Day_1 Day_2 Day_3
user1 2 2 1
user2 4 0 1
user3 8 0 0
user4 0 0 0
</code></pre>
<p>Now, I need to check if a user had any impression in the past <code>n</code> days. For example, if <code>num_days = 2</code>, I need to add a new column, <code>impression</code>, where it gets 1 if sum Day_1 and Day_2 is greater than zero, and <code>0</code> otherwise. Here is what I expect to see:</p>
<pre><code> Day_1 Day_2 Day_3 impression
user1 2 2 1 1
user2 4 0 1 1
user3 8 0 0 1
user4 0 0 0 0
</code></pre>
<p>It is a straightforward process in <code>pyspark</code> and I use something like this:</p>
<pre><code>imp_cols = ['Day_'+str(i) for i in range(1, num_days+1)]
df = df.withColumn("impression",reduce(add, [F.col(x) for x in imp_cols]))
</code></pre>

<p>Any simple link to an external site from my Blazor Server site works....but while the site loads the user sees the Blazor "Attempting to reconnect to the server: 1 of 8" message first.</p>
<p>How do I get rid of that and provide a more seamless experience?</p>
<p>I have tried coding my own javascript exit routine by listening to the click event and manually doing window.location.href = url; with the same results.</p>
<p>I have also tried calling Blazor.disconnect() before jumping to the external site, but again no luck.</p>
<p>I tried embedding calls to a NavigationManager in my code, but that's really ugly, and I didn't have much luck with that either.</p>
<p>...surely a very simple scenario! - my code is simply:</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-html lang-html prettyprint-override"><code><a href="https://www.google.com">Go</a></code></pre>
</div>
</div>
</p>

<p>I have two Tcl lists of equal length, <code>u</code> and <code>v</code>. Many of the entries in <code>u</code> are known to be identical. For every unique entry in <code>u</code>, I would like to average over the corresponding entries in <code>v</code>. So, if my lists are <code>{1 2 1 2}</code> and <code>{1 2 3 4}</code>, the output should be <code>{1 2}</code> (only the unique entries in <code>u</code>), and <code>{2 3}</code>, where 2 comes from <code>(1+3)/2</code>, and 3 comes from <code>(2+4)/2</code>.</p>
<p>I have tried the following:</p>
<pre><code>set unique [lsort -unique $u]
foreach i $unique {
set ave 0; set N 0
foreach j $u k $v {
if {$i == $j} {set ave [expr {$ave+$k}]}
}
lappend w [expr {$ave/$N}]
}
</code></pre>
<p>This works, but it is far too slow for larger lists. Does anyone know a more efficient way of doing this?</p>
<p>Thanks in advance!</p>

<p>I am trying to create a table of elements (structs) where each element contains a dynamic list of enums in C. However, it seems this is not possible in C as I keep getting the following error:</p>
<pre><code>error: initialization of flexible array member in a nested context
</code></pre>
<p>Here is a small sample of my code:</p>
<pre><code>#include <stdio.h>
#include <stdint.h>
typedef enum {
NET_0 = 0,
NET_1,
NET_2,
TOTAL_NETS,
} net_t;
typedef struct {
uint8_t num_nets;
net_t net_list[];
} sig_to_net_t;
sig_to_net_t SIG_NET_MAPPING[] = {
{1, {NET_0}},
{2, {NET_1, NET_2}},
{1, {NET_2}},
};
</code></pre>
<p>Any solution for this issue in C?</p>
<p>FYI, the only solution I found would be to replace the dynamic array <code>net_list</code> with a fixed-size array. However, this solution is not optimal as this code will be flashed on memory-limited devices and I have cases where the <code>net_list</code> will contain 5 elements which are only a few cases out of 1000 entries in the <code>SIG_NET_MAPPING</code> table.</p>

<p>I have two vectors and I am trying to find all unique combinations of 3 elements from vector1 and 2 elements from vector2. I have tried the following code.</p>
<pre><code>V1 = combn(1:5, 3) # 10 combinations in total
V2 = combn(6:11, 2) # 15 combinations in total
</code></pre>
<p>How to combine V1 and V2 so that there are 10 * 15 = 150 combinations in total? Thanks.</p>

<p>I am having a problem.
I have rented a revolving proxy from a web service and I want to change the IP continuously via the api. I used the requests module to get a new IP, so how can it automatically get that new IP and replace it with the old one to use? I'm a newbie and really don't know much, hope someone can help me. Thanks very much!</p>
<p>I read the instructions of the service site but they don't have a tutorial for python</p>

<p>I have a use case where depending on the argument passed in I may have to fetch and process 1) millions or records from database (read rdbms using jdbc, decode, convert to xml, convert to csv etc., a very time consuming process), and or 2) process only a few hundres or even handful of records. Please note that I do not know the volume of the data in this multi-tenant spark app until during the runtime of my app where I calculate total # of records I need to process. So I have two questions here:</p>
<ol>
<li>How do I know how many executors or cores I need to request for this spark job without knowing the data volume as I kick off the run.</li>
<li>Because I making jdbc calls on a DB table, I am using the numOfPartitions, lowerbound(0), upperBound(total#OfRecords), and partitioncolumn(ROW_NUM) to parition the SparkSQL. Now how do I calculate the numOfPartitions? In one case when I am fetching millions I want to have more paritions and less for a handful. How do I decide this number? What is the logic? Would this numOFPartition be 10-20 for 100-200? We dont want to affect transaction applications by hoggin DB resources. How do people typically decide on ths numOfPartitions?
Appreicate your help
thank you</li>
</ol>
<p>Need help deciding database numOfPartitions</p>

<p>I'm trying to concatenate all rows for same ID, the rows for a ID can have null or empty value:</p>

</div>
<p>I would like to consider this case in my query to get this result:</p>
<div class="s-table-container">

</div>
<p>We can consider to replace null value to get this result</p>
<div class="s-table-container">
<table class="s-table">

<tbody>

<p>I'm trying to create a background modal that's supposed to fill the entire height of the page.
The modal only fills about half the page, around 950px (which is the 100% viewable portion).
Tried to change the units, tried using calc, used wrapping components.</p>
<p>P.S. When the modal is called by JS the display changes from none to block</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>#modalBackground {
display: none;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgb(0 0 0 / 0.7);
z-index: 10;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><body>
...stuff
<div id="modalBackground"></div>
...stuff

<p>Create Folder for Each File in Recursive Directory, Placing File in Folder</p>
<p>On MacOS, so far I have...</p>
<pre><code>for file in $(ls -R); do
if [[ -f "$file" ]]; then mkdir "${file%.*}"; mv "$file" "${file%.*}"; fi;
done
</code></pre>
<p>This operates correctly on the top level of the nested folder, but does nothing with lower levels.</p>
<p>To isolate the error, I tried this instead, operating on rtf files . .</p>
<pre><code>for i in $(ls -R);do
if [ $i = '*.rtf' ];then
echo "I do something with the file $i"
fi
done
</code></pre>
<p>This hangs, so I simplified to . .</p>
<pre><code>for i in $(ls -R); do echo "file is $i" done
</code></pre>
<p>That hangs also, so I tried . .</p>
<pre><code>for i in $(ls -R); do echo hello
</code></pre>
<p>That hangs also.</p>
<p><code>ls -R</code> works to provide a recursive list of all files.</p>
<p>Suggestions appreciated !!</p>

<p>I have this function on my code that is supposed to read a files last line, and if there is no file create one. My issue is when it creates the files and tries to read the last line it comes up as an error.</p>
<pre><code>with open(HIGH_SCORES_FILE_PATH, "w+") as file:
last_line = file.readlines()[-1]
if last_line == '\n':
with open(HIGH_SCORES_FILE_PATH, 'a') as file:
file.write('Jogo:')
file.write('\n')
file.write(str(0))
file.write('\n')
</code></pre>
<p>I have tried multiple ways of reading the last line but all of the ones I've tried ends in an error.</p>

<p>I need to add the column for table that if the column is not existed.</p>
<p>I ran the <code>Alter Table <table> add <column_name> <type>;</code> however, it will have this error message if the column already exists.</p>
<pre><code>InvalidRequest: Error from server: code=2200 [Invalid query] message="Invalid column name <column_name> because it conflicts with an existing column"
</code></pre>
<p>Does it have a way to do a similar check on whether the column exists or not?</p>

<p>Lets say there are functions</p>
<pre><code>function a(someparams){
console.log('a called')
}
function b(){
console.log('b called')
}
...
const c (someParam) => { console.log('c called')}
</code></pre>
<p>I want to extend default function prototype something like
<code>Function.prototype.onCall = (args) => {console.log('Proxy fn called!',args)}</code>
in a very begining of a page code, so every existing and new functions, upon call, will log 'Proxy fn called!'.
There are solutions to map window.functions - but they only work for existing functions, and I want to extend prototype to let it execute my piece of code.
The goal is to automatically check if args are valid. No I don't want typescript or flow, thanks for suggestion.
Is this possible? where to look at?</p>
<p>I found</p>
<pre><code>(function() {
var call = Function.prototype.call;
Function.prototype.call = function() {
console.log(this, arguments); // Here you can do whatever actions you want
return call.apply(this, arguments);
};
}());
</code></pre>
<p>to be the closest to what I want so far, but these aren't called when calling a function normally, e.g. <code>someFunction();</code>, without explicit <code>.call</code> or <code>.apply</code>.</p>
<p>I have found maybe decorators is a way to go? the official doc said they are still not a standard <a href="https://github.com/tc39/proposal-decorators" rel="nofollow noreferrer">https://github.com/tc39/proposal-decorators</a> but there is a babel plugin <a href="https://babeljs.io/docs/en/babel-plugin-proposal-decorators" rel="nofollow noreferrer">https://babeljs.io/docs/en/babel-plugin-proposal-decorators</a> is it possible that it would do the job or am I looking into wrong direction?</p>

<p>I'm reading an introducty book about C and I came across the following paragraph:</p>
<p><a href="https://i.stack.imgur.com/5QygF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5QygF.png" alt="enter image description here" /></a></p>
<p>But the following code compiles with expected output:</p>
<pre><code>#include <stdio.h>
int main()
{
for(int i = 0; i<=10; i++)
{
int val = i + 1;
int x = val * val;
printf("%d\n", x);
int y = x;
}
return 0;
}
</code></pre>
<p>I use <a href="https://www.onlinegdb.com/" rel="nofollow noreferrer">https://www.onlinegdb.com/</a> and in the above code I declared many variables after the first executable statement. And this is to me does not match what the section from the book tells.</p>
<p>Am I misunderstanding what the book is telling?</p>

<p>I am working with a number of custom classes <code>X</code> that have <code>__add__(self)</code>, and when added together return another class, <code>Y</code>.</p>
<p>I often have iterables [of various sizes] of <code>X</code>, <code>ex = [X1, X2, X3]</code> that I would love to add together to get <code>Y</code>. However, <code>sum(ex)</code> throws an <code>int</code> error, because <code>sum</code> starts at 0 which can't be added to my class <code>X</code>.</p>
<p>Can someone please help me with an easy, pythonic way to do <code>X1 + X2 + X3 ...</code> of an interable, so I get <code>Y</code>...</p>
<p>Thanks!</p>
<p>Ps it’s a 3rd party class, X, so I can’t change it. It does have <em>radd</em> though.</p>
<p>My gut was that there was some way to do list comprehension? Like += on themselves</p>

<p>It's my first post on the stackoverflow so I apologize in advance if I am doing something wrong.</p>
<p>I'm new to Cypress E2E test. Im trying to write a test for react WebApplication.
Unfortunately I am stuck on the element when the application on mobile views e.g. viewPort 360 opens in full screen. The application is doing that when I interact with the first element (login page). After filling the login field spec then stops with the message "(uncaught exception) TypeError: Fullscreen request denied".</p>
<p>Is there any way to work around this? On higher resolutions where full screen is not opened spec passes without problem.</p>
<p><a href="https://i.stack.imgur.com/CUBHg.png" rel="nofollow noreferrer">Screen with the error from Cypress</a></p>
<p>I was searching if there is a parameter in Cypress settings to disable the blocker for full screen , unfortunately I did not find anything.
The same problem occurs on Chrome and Firefox.</p>
<p>The spec code is very simple</p>
<p>I use the class from POM</p>
<pre class="lang-js prettyprint-override"><code>class Homepage_PO {
Visit_Homepage(){
cy.visit(Cypress.env('integrax_homepage'),{timeout:60000})
}
Login(login, password){
cy.get('input[name="login"]').type(login)
cy.get('input[name="password"]').type(password)
cy.get('#loginBtn').click()
}
}
export default Homepage_PO;
</code></pre>
<p>and the spec code</p>
<pre class="lang-js prettyprint-override"><code>import Homepage_PO from "../../support/pageObjects/integraX/Homepage_PO";
/// <reference types = 'cypress'/>
describe('Log in into IntegraX', () => {
const homepage_PO = new Homepage_PO()
beforeEach(() => {
homepage_PO.Visit_Homepage();
});
it.only('log in as Integra administrator', () => {
homepage_PO.Login(Cypress.env('integra_admin_login'), Cypress.env('integra_admin_password'));
});
it('log in as Car Service', () => {
});
});
</code></pre>

<p>I have a yearly table which on a monthly basis will append data from another table. However, I need to check the max date on the monthly table before appending it. If the max date on monthly is same as YTD, then do not append else append. How can I achieve this in SAS.</p>
<p>I tried using append but don't know how to check the dates before appending.</p>

<p>the goal is to move between rooms in this simplified version of a text base game. The code works exactly as planned except for if you try and input 'exit' directly after inputting 'instructions'. after inputting 'instructions' the first 'exit' get ran in the else invalid statement then the second 'exit' input exits the game as intended. If you continue at least one input after 'instructions' than exit works properly as well.</p>
<pre><code>rooms = {
'Great Hall': {'South': 'Bedroom'},
'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
'Cellar': {'West': 'Bedroom'}
}
def instruction():
"""Function to give instructions on how to play the game"""
print('Welcome to Module 6 Milestone')
print('Move commands are go North, go South, go East, go West')
print('Typing exit will exit the game')
print('Inputting instructions will remind you of the game instructions')
print('Good luck may the odds be in your favor')
def invalid():
"""Function for if an invalid input is entered"""
print('------------')
print('Whoops invalid command, try again')
print('------------')
def main():
"""Main function that runs the movement between rooms"""
current_room = 'Great Hall'
print('\nYou are starting in the', current_room)
move = input('What will you do next?\n>').split()
directions = ['North', 'South', 'East', 'West'] # directions in the dictionary
while True:
if len(move) < 2: # for one word inputs
if 'exit' in move: # exit the game
print('\nThanks for playing!')
break
elif 'instructions' in move: # reprint instructions
instruction()
print('------------')
print('\nYou are in the', current_room)
else:
invalid()
print('You are still in the', current_room)
move = input('\nWhat will you do next?\n>').split() # next move input
if len(move) == 2: # 2 word inputs
if move[1] in directions: # checks if move is a valid direction
if move[1] in rooms[current_room]: # if move is a valid direction in current room
current_room = rooms[current_room][move[1]] # changes current room if valid

<p>I am attempting to create an SQL query which will compress multidimentional data using PIVOT, but need to do some operations on the pivoted data.</p>
<p>I have coding experience but very little experience with SQL and am using SQLPathfinder3 to create and execute queries, so what I am looking for is top level approach - what order of operations should I be going for here to achieve the desired result?</p>
<p>An example of my initial result table, gotten with SELECT, is as follows:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Item</th>
<th>Property</th>
<th>Subproperty</th>
<th>Thing</th>
</tr>
</thead>
<tbody>
<tr>
<td>item1</td>
<td>propertyA</td>
<td>subproperty1</td>
<td>value1_A_1</td>
</tr>
<tr>
<td>item1</td>
<td>propertyA</td>
<td>subproperty2</td>
<td>value1_A_2</td>
</tr>
<tr>
<td>item1</td>
<td>propertyB</td>
<td>subproperty1</td>
<td>value1_B_1</td>
</tr>
<tr>
<td>item1</td>
<td>propertyB</td>
<td>subproperty2</td>
<td>value1_B_2</td>
</tr>
<tr>
<td>item2</td>
<td>propertyA</td>
<td>subproperty1</td>
<td>value2_A_1</td>
</tr>
<tr>
<td>item2</td>
<td>propertyA</td>
<td>subproperty2</td>
<td>value2_A_2</td>
</tr>
<tr>
<td>item2</td>
<td>propertyB</td>
<td>subproperty1</td>
<td>value2_B_1</td>
</tr>
<tr>
<td>item2</td>
<td>propertyB</td>
<td>subproperty2</td>
<td>value2_B_2</td>
</tr>
</tbody>
</table>
</div>
<p>By executing one pivot, assigning Subproperty as the CTHEADER, and Thing as the CTVALUE, I can create this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Item</th>
<th>Property</th>
<th>Subproperty1</th>
<th>Subproperty2</th>
</tr>
</thead>
<tbody>
<tr>
<td>item1</td>
<td>propertyA</td>
<td>value1_A_1</td>
<td>value1_A_2</td>
</tr>
<tr>
<td>item1</td>
<td>propertyB</td>
<td>value1_B_1</td>
<td>value1_B_2</td>
</tr>
<tr>
<td>item2</td>
<td>propertyA</td>
<td>value2_A_1</td>
<td>value2_A_2</td>
</tr>
<tr>
<td>item2</td>
<td>propertyB</td>
<td>value2_B_1</td>
<td>value2_B_2</td>
</tr>
</tbody>
</table>
</div>
<p>Similarly, I can pivot around "Subproperty" to get something analogous:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Item</th>
<th>Subproperty</th>
<th>Property A</th>
<th>Property B</th>
</tr>
</thead>
<tbody>
<tr>
<td>item1</td>
<td>subproperty1</td>
<td>value1_A_1</td>
<td>value1_A_2</td>
</tr>
<tr>
<td>item1</td>
<td>subproperty2</td>
<td>value1_B_1</td>
<td>value1_B_2</td>
</tr>
<tr>
<td>item2</td>
<td>subproperty1</td>
<td>value2_A_1</td>
<td>value2_A_2</td>
</tr>
<tr>
<td>item2</td>
<td>subproperty2</td>
<td>value2_B_1</td>
<td>value2_B_2</td>
</tr>
</tbody>
</table>
</div>
<p>The final result that I need is this - a combination of the above values:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Item</th>
<th>Property A</th>
<th>Property B</th>
</tr>
</thead>
<tbody>
<tr>
<td>item1</td>
<td>value1_A_1 + value1_A_2</td>
<td>value1_B_1 + value1_B_2</td>
</tr>
<tr>
<td>item2</td>
<td>value2_A_1 + value2_A_2</td>
<td>value2_B_1 + value2_B_2</td>
</tr>
</tbody>
</table>
</div>
<p>I don't know how to go about doing this in a single query, but I would very much like to, because this is something that needs to be automated.</p>
<p>I can't simply SELECT the sums that I want, because those values are on four separate lines. I could workaround in excel or python, especially if I can effect the result below, but I'm not sure how to do this.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Item</th>
<th>PropA Sub1</th>
<th>PropA Sub2</th>
<th>PropB Sub1</th>
<th>PropB Sub2</th>
</tr>
</thead>
<tbody>
<tr>
<td>item1</td>
<td>value1_A_1</td>
<td>value1_A_2</td>
<td>value1_B_1</td>
<td>value1_B_2</td>
</tr>
<tr>
<td>item2</td>
<td>value2_A_1</td>
<td>value2_A_2</td>
<td>value2_B_1</td>
<td>value2_B_2</td>
</tr>
</tbody>
</table>
</div>
<p>Any help, or pointers towards educational material would be appreciated, thanks.</p>

<p>I'm trying to create <code>Match</code> between two <code>User</code>'s. However i'm getting this error</p>
<pre><code>Microsoft.EntityFrameworkCore.DbUpdateException: An error occurred while saving the entity changes. See the inner exception for details.
---> Microsoft.Data.SqlClient.SqlException (0x80131904): Violation of PRIMARY KEY "PK_Users" constraint. Cannot insert duplicate key into object 'dbo.Users'. Duplicate key value: (0c7a0cdc-a7ba-4cf8-ade2-0cef44761597).

<p>I have this entities</p>
<pre><code>public class Match

await _unitOfWork.SaveChangesAsync(cancellationToken);
return matchId;

<p>MatchRepository</p>
<pre><code>public async Task<Guid> CreateAsync(Match match)

<p><strong>What am I trying to do</strong></p>
<p>I have 3 tables which are being joined to create a desired output.</p>
<p>Table 1 (800K records) : This is a partitioned hive external table by date (parquet file structure ). The schema is deeply nested. Following is a portion of the schema</p>
<pre><code>root
| - uuid
| - data
| - k1 - string
| - k2 - string
| - ...
| ….
| - dt - string (partition column)
</code></pre>
<p>Table 2 (0.5 million records) /Table 3 (31K records) : metadata tables</p>
<pre><code>root
| - insert_date
| - k_sub
| - action_date
| ….
</code></pre>
<p>SQL being executed (Generated by a internal library)</p>
<pre><code>SELECT input_file_name() as filename, uuid, data.k1, data.k2, dt
FROM table_1
WHERE NOT EXISTS(SELECT 1 FROM table_2 WHERE (k_sub = data.k1) AND dt > action_date)
AND EXISTS(
SELECT 1 FROM table_3 WHERE (k_sub = data.k1) AND (dt < action_date OR dt < DATE_ADD(CURRENT_DATE(), -1460))
</code></pre>
<p>Spark settings</p>
<pre><code>Num of executors = 50
Executor memory = 10g
Driver memory = 10g
</code></pre>
<p>The query runs very slow runs for 1.1 hrs and fails. Looking into the sparkUI (SQL table).</p>
<p>I increased the num of executors to 100 and the job completed but I'm not confident. The plan looks like this</p>
<p><a href="https://i.stack.imgur.com/oOHcN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oOHcN.png" alt="enter image description here" /></a></p>
<p>Based on my research, <code>BroadcastNestedLoopJoin</code> is not good to have. As it is SQL, I tried adding /* +BroadcastJoin */ hint but still did not help. Anyone has thoughts of how I could approach this problem and improve the performance?</p>

<p><a href="https://i.stack.imgur.com/fqPQU.png" rel="nofollow noreferrer">The primary style is showing correctly as seen here when I change my code</a></p>
<p>I checked the DOM and the css also shows the color to appear this way.
<a href="https://i.stack.imgur.com/qB57Z.png" rel="nofollow noreferrer">Screenshot from the inspect developer tool</a></p>
<p>Thank you for reading and I would really appreciate it if you could help. P.S. How do I make it so that my pictures appear instead of links to click. I pasted them in so if there is another way please advise. Again, thank you.</p>
<p>I checked over my code and made sure nothing was overriding the styles. There is nothing that I noticed. It is a very small project.</p>
<p>I also tested the other default button styles, and they appeared as shown on the bootstrap documentation page.</p>
<p>I tested my code in the Chrome Browser and it also is appearing this way.</p>

<p>On my midterm there was a question that I believe has two correct answers, A and B. The question states:</p>
<blockquote>
<p>Which of the following sets of operators is composed only of comparative operators?<br />
A) >, <, >=, <=<br />
B) ==, !=<br />
C) &&, ||, !<br />
D) None of the above.</p>
</blockquote>
<p>Page 235 of my textbook (Computer Science: A Structured Programming Approach Using C by Forouzan and Gilberg) states,</p>
<blockquote>
<p>C provides six comparative operators. … The operators are shown in Figure 5-4.</p>
</blockquote>
<p>Figure 5-4 shows the operators <, <=, >, >=, ==, and !=. I emailed this to my lecturer and she responded with:</p>
<blockquote>
<p>I understand the point you made in your submitted paper, but the best course of action is to stick to CS159 notes packet rather than Forouzan's textbook, as the textbook is considered a supplemental resource for this course.</p>
</blockquote>
<p>Page 119 of my notes packet (Purdue University's CS159 notes packet) says that comparative operators are == and !=. So does comparative operator have two definitions? Even in that case the question would have two correct answers.</p>

<p>I want to generate a dataframe with pandas where one of the columns is filled with all mondays between to dates. But I need to exclude some mondays that are in a specific list. I could generate the column with the mondays, but I could find how to remove that mondays in the given list.</p>
<p>I generate the mondays using:</p>
<p>import pandas as pd</p>
<p>st=pd.to_datetime('8/22/2022')
ed=pd.to_datetime('12/22/2022')</p>
<p>a1=pd.date_range(start=st,end=ed, freq='W-MON')</p>
<p>But I would like to exclude the mondays that are in this list</p>
<p>fer=pd.to_datetime(['09/07/2022','10/12/2022','10/15/2022','10/28/2022','11/01/2022','11/14/2022','11/15/2022','11/20/2022'])</p>
<p>I was not able to find the solution online.</p>

<pre><code>query(meetingsCollection, where("start", "in", today), orderBy("start", "asc")
</code></pre>
<p>I'd like a Firestore query, so that I can fetch all documents between 02/12/2022 - 00:00:00.000 && 03/12/2022 00:00:00.000, ordered by the Date property start, so that I can bucketsize my firestore data request and limit overreads, then use said documents to visually filter accordingly via the front-end.</p>
<p>Can you assist me with this?</p>

<p>I have a client server that has limited rights (no internet or many install priveleges), but it contains a version of TFS. Is there any way possible to get the data and history to bring down to my local computer to put into GIt?</p>
<p>I have tried Git-TFS but cannot get it installed on the server and tried running the source code.</p>
<p>Any ideas besides me downloaded the code for each branch and then adding them in branch by branch and ignoring the previous commits of each branch?</p>

<p>At the moment I'm hacking away at swift to learn the language and I'm coming at it from a java/C++ perspective. I'm trying to make an app for a game I play called World War II Online. However I can't get my head around why I'm getting a binding error when trying to code in the toggle for remembering a password. Below is my code for the landing page for my app.</p>
<pre><code>struct ContentView: View {
@State private var empty_field = ""
@State private var passwordState = false
let userfieldTitle : String = "username"
let passwordFieldTitle : String = "password"
let landingPageTitle = "World War II Online"
let toggleName = "remember password"
var body: some View
{
Text(landingPageTitle).font(.largeTitle)
Section {
Form{
VStack
{
TextField(userfieldTitle,text : $empty_field)
TextField(passwordFieldTitle,text : $empty_field)
Toggle(toggleName, isOn: $passwordState){
print("hello world")
}
}
.padding()
}
}
}
</code></pre>
<p>I'm getting the error:</p>
<p><strong>Cannot convert value of type 'Binding' to expected argument type 'KeyPath<(() -> ()).Element, Binding>'</strong></p>
<p>I'm really bad in understanding bindings and properties. Is there something I've been code blind to ?</p>

<p>So by far whenever I had a dataframe that has a column of list such as the following:</p>
<pre><code>'category_id'
[030000, 010403, 010402, 030604, 234440]
[030000, 010405, 010402, 030604, 033450]
[030000, 010403, 010407, 030604, 030600]
[030000, 010403, 010402, 030609, 032600]
</code></pre>
<p>Usually whenever I want to make this category_id column become like:</p>
<pre><code>'category_id'
030000
010403
010402
030604
234440
030000
010405
010402
030604
033450
</code></pre>
<p>I would usually use the following code:</p>
<pre><code>df2 = df.explode('category_id')
</code></pre>
<p>But whenever my data size gets really big, likes the sales data over the course of an entire month, .explode() becomes extremely slow and I am always worried whether I would encounter any OOM issues related to memory leaks.</p>
<p>Is there any other alternative solutions to .explode that would somehow perform better?
I tried to to use flatMap() but I'm stuck on how to exactly turn a dataframe to rdd format and then change it back to dataframe format that I can utilize.</p>
<p>Any info would be appreciated.</p>

<p>I was curious about how I can implement the Fibonacci sequence for summing the last n elements instead of just the last 2. So I was thinking about implementing a function <code>nBonacci(n,m)</code> where n is the number of last elements we gotta sum, and m is the number of elements in this list.</p>
<p>The Fibonacci sequence starts with 2 ones, and each following element is the sum of the 2 previous numbers.</p>
<p>Let's make a generalization: The nBonacci sequence starts with n ones, and each following element is the sum of the previous n numbers.</p>
<p>I want to define the nBonacci function that takes the positive integer n and a positive integer m, with m>n, and returns a list with the first m elements of the nBonacci sequence corresponding to the value n.</p>
<p>For example, <code>nBonacci(3,8)</code> should return the list [1, 1, 1, 3, 5, 9, 17, 31].</p>
<pre><code>def fib(num):
a = 0
b = 1
while b <= num:
prev_a = a
a = b
b = prev_a +b
</code></pre>
<p>The problem is that I don't know the number of times I gotta sum. Does anyone have an idea and a suggestion of resolution?</p>

</code></pre>
<p>here's my code.
I've seen many codes that calculate the days between two dates, but they didn't use class Date.
how can i solve this problem? could you guys help me please.I'm sorry i'm new in c++ so, my problem might be so basic.</p>

<p>It is necessary for me at a choice chekboksom that the Page2 component was drawn. I created a <code>useState</code> where I keep track of the value of the checkbox, but I don't know how to navigate programmatically when the checkbox is selected. How can I do this?</p>
<pre><code>export default function Home() {
const [checked, setChecked] = useState(false);
const navigate = useNavigate();
const handleChange = () => {
setChecked(!checked);
};
return (
<>
<input type="checkbox" onChange={handleChange}></input>
</>
);
}
</code></pre>

<p>I am learning JS prototype, and I got the following code, all is clear except the output of <code>console.log(myObj.name)</code>. How come it gives the name of the object itself, which is <code>myObj</code>? Doesn't it need to find the prototype from its upper-level object?</p>
<pre><code>const myObj = function () {}
myObj.prototype.name = 'prototype.name'
myObj1 = new myObj()
console.log(myObj.name) // => myObj
console.log(myObj1.name) // => 'prototype.name'
console.log(myObj.prototype.name) // => prototype.name
</code></pre>
<p>I was expecting the same output as <code>myObj1</code> and their prototype.</p>

<p>I have seen may tutorials on making the first row the column names, but nothing explaining how to do the reverse. I would like to have my column names as the first row values and change the column names to something like var1, var2, var3. Can this be done?</p>
<p>I plan to row bind a bunch of data frames later, so they all need the same column names.</p>
<pre><code>q = structure(list(shootings_per100k = c(8105.47466098618, 6925.42653239307
), lawtotal = c(3.00137104283906, 0.903522788541896), felony = c(0.787418655097614,
0.409578330883717)), row.names = c("mean", "sd"), class = "data.frame")
</code></pre>
<p><strong>Have:</strong></p>
<pre><code> shootings_per100k lawtotal felony
mean 8105.475 3.0013710 0.7874187
sd 6925.427 0.9035228 0.4095783
</code></pre>
<p><strong>Want:</strong></p>
<pre><code> var1 var2 var3
var shootings_per100k lawtotal felony
mean 8105.475 3.0013710 0.7874187
sd 6925.427 0.9035228 0.4095783
</code></pre>
<p><strong>edit:</strong> I just realized that since I plan to row bind several data frames later, it may be best for them to all have the same column names. I changed the 'want' section to reflect the desired outcome.</p>

<p>I have the following dataset:</p>
<pre><code> Letter ID Number
A A1 1
A A2 2
A A3 3
B B1 1
B B2 2
B B3 3
B B4 4
</code></pre>
<p>My aim is first to create all possible combinations of IDs within the same "Letter" group. For example, for the letter A, it would be only three combinations: A1-A2,A2-A3,and A1-A3. The same IDs ordered differently don't count as a new combination, so for example A1-A2 is the same as A2-A1.</p>
<p>Then, within those combinations, I want to add up the numbers from the "Number" column associated with those IDs. So for the combination A1-A2, which are associated with 1 and 2 in the "Number" column, this would result in the number 1+2=3.</p>
<p>Finally, I want to place the ID combinations, added numbers and original Letter in a new data frame. Something like this:</p>
<pre><code>Letter Combination Add.Number
A A1-A2 3
A A2-A3 5
A A1-A3 4
B B1-B2 3
B B2-B3 5
B B3-B4 7
B B1-B3 4
B B2-B4 6
B B1-B4 5
</code></pre>
<p>How can I do this in R, ideally using the package dplyr?</p>

<p>I am making a simple game with multiple players, which each player can insert their first name, last name and each player is assigned 100 poins at the begging. In my code once I am done with coding the "essential" information, but when it comes to user input it does not work.</p>
<p>The "base" for the player class: (this part works)</p>
<pre><code>class Players():
def __init__ (self, firstname, lastname, coins): #initialising attributes
self.firstname = firstname
self.lastname = lastname
self.coins= coins
def full_info(self):
return self.firstname + self.lastname + self.coins
</code></pre>
<p>This is the second part where the problem is, the input is not stored in the attributes</p>
<pre><code> def get_user_input(self):
firstname= input("Please enter your first name:")
lastname= input ("Please enter your second name: ")
coins= 100 #they are assigned automatically
return self(firstname, lastname, coins)
</code></pre>
<p>I would appriciate any suggesting regarding the user input.</p>

<p>I am new to typescript and converting my jsx to tsx files. How can I define the type for a redux dispatch for my <code>onPress</code> prop? I tried using "Function" and the "AppDispatch". Thanks in advance</p>
<pre><code>import { AppDispatch } from "../redux/store"
interface ItemProps {
item: Custom_date,
onPress: AppDispatch, //What should I put here?
backgroundColor: any,
textColor: any
}
const Item = ({ item, onPress, backgroundColor, textColor }: ItemProps) => (
<TouchableOpacity onPress={onPress} style={[styles.item, backgroundColor]}>
<Text style={[styles.dateTitle, textColor]}>{item.title}</Text>
</TouchableOpacity>
);
export const DateHeader = () => {
const { date } = useSelector((store: RootState) => store.nutrition)
const dispatch = useDispatch()
const renderItem = ({ item }) => {
const backgroundColor = item.id === date.id ? "#033F40" : "#BDF0CC";
const color = item.id === date.id ? '#BDF0CC' : '#033F40';
return (
<Item
item={item}
onPress={() => dispatch(setDate(item))}
backgroundColor={{ backgroundColor }}
textColor={{ color }}

<p>I was curious on how wheel spinning based of chances algorithm would work so I wrote this code</p>
<p>I created an object with each prize and its probability</p>
<pre><code>const chances = {
"Apple" : 22.45,
"Peaches" : 32.8,
"Grapes" : 20,
"Bananas" : 6.58,
"Strawberry" : 18.17
}
</code></pre>
<p>then I generate a random number and check if its within the prize's winning ranges</p>
<pre><code>const random = Math.floor((Math.random() * 10000) + 1);
var rangeStart= 0;
for (var key in chances){
var rangeEnd= rangeStart+ chances[key];
if (rangeStart*100 < random && random <= rangeEnd*100){
console.log(rangeStart*100+" < "+random+" <= "+rangeEnd*100);
console.log("You won a "+key)
break;
}
rangeStart+= chances[key];
}
</code></pre>
<p>you can check the code <a href="https://jsfiddle.net/5h9tygkd/1/" rel="nofollow noreferrer">here</a></p>
<p>am I in the right path?</p>

<p>I'm quite new to SQL so bare with me. What I'm trying to do is return the value closest to another value in a different table for every record.</p>
<p>I'll show a simplified example of my two tables for clarification</p>
<p>First table is the one that I want the value ENTRY_YEAR matched to:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>ENTRY_VALUE</th>
</tr>
</thead>
<tbody>
<tr>
<td>1001</td>
<td>1900</td>
</tr>
<tr>
<td>1002</td>
<td>2000</td>
</tr>
</tbody>
</table>
</div>
<p>And the second table:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>ENTRY_VALUE</th>
<th>STATUS</th>
</tr>
</thead>
<tbody>
<tr>
<td>1001</td>
<td>1880</td>
<td>SUCCES</td>
</tr>
<tr>
<td>1001</td>
<td>1930</td>
<td>FAIL</td>
</tr>
<tr>
<td>1001</td>
<td>1940</td>
<td>SUCCES</td>
</tr>
<tr>
<td>1002</td>
<td>1960</td>
<td>SUCCES</td>
</tr>
<tr>
<td>1002</td>
<td>1980</td>
<td>FAIL</td>
</tr>
</tbody>
</table>
</div>
<p>So the end result I'm looking for is:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>ID</th>
<th>ENTRY_VALUE</th>
<th>STATUS</th>
</tr>
</thead>
<tbody>
<tr>
<td>1001</td>
<td>1880</td>
<td>SUCCES</td>
</tr>
<tr>
<td>1002</td>
<td>1980</td>
<td>FAIL</td>
</tr>
</tbody>
</table>
</div>
<p>I have currently only managed to link the id's together but can't find a way to compare the ENTRY_VALUE in both tables and return the one closest to the Table1 entry.</p>
<p>So only this:</p>
<pre><code>SELECT * from Table2
INNER JOIN Table1 ON (Table2.ID = Table1.ID)
</code></pre>
<p>Once again my bad for the basic question, I have googled right about everything but can't get it to work so any help is very welcome!</p>

<p>I was going through this question on leetcode: <a href="https://leetcode.com/problems/determine-if-two-strings-are-close/solutions/935916/c-o-nlogn-sort-hash-table-easy-to-understand/" rel="nofollow noreferrer">https://leetcode.com/problems/determine-if-two-strings-are-close/solutions/935916/c-o-nlogn-sort-hash-table-easy-to-understand/</a></p>
<pre><code>class Solution {
public:
bool closeStrings(string word1, string word2) {
if(word1.size()!=word2.size())
return false;
int n = word1.size();
vector<int>freq1(26,0);
vector<int>freq2(26,0);
for(int i= 0 ; i < n ; ++i){
freq1[word1[i]-'a']++;
freq2[word2[i]-'a']++;
}
sort(freq1.rbegin(),freq1.rend());
sort(freq2.rbegin(),freq2.rend());
**if(set(word1.begin(),word1.end())!=set(word2.begin(),word2.end()))**
return false;
for(int i= 0;i<26;++i){
if(freq1[i]!=freq2[i])
return false;
}
return true;
}
};
</code></pre>
<p>I am not understanding what does <code>set(word1.begin(),word1.end())</code> mean over here, I tried to search on the internet for answer but I didn't got any satisfying answer, if someone can explain it would be very helpful. Thanks in advance!</p>

<p>Today we used the consult for recive a pattern of data, and, with this pattern select the results:</p>
<pre><code>SELECT
pm.meta_value, MONTH(RTRIM(LTRIM(SUBSTRING(pm.meta_key,23,10)))) as month
FROM wp_postmeta pm
</code></pre>
<p><strong>The problem is</strong>: The consulting are stay slowed, and, we cant change the database.
How i can make this consult stay more speed? I'm yet trying put the index, but, not solved.</p>
<p>The pattern is filter the string in wp_postmeta and retry get the month.</p>
<p><strong>For example</strong>:</p>
<ul>
<li>string-with-any-name-of-day-2022-01-32, so, we filtering this string with rtrim and substring for get the month.</li>
</ul>
<p>I'm tryed put the index in table wp_postdata in column meta_key and meta_value, but this not solved my problem.</p>
<p>I yet think in create other table for storage this meta data, but, the problem is gonna continue.</p>

</script>
<a href="/" onclick="location.href=this.href+firstpath;return false;">
<img />
</a>

<p>I am creating a form that allows the user to select from a group of checkboxes for automotive services. In the form, the user selects from a list of priced services and a final total is calculated based on what is selected.</p>
<p>The logic of the selected services being added up is
placed within a method that returns the total.</p>
<p><img src="https://i.stack.imgur.com/hR4ZX.png" alt="photo of form" />.</p>
<p>Once the user clicks on the calculate button, all selected prices will be added up and displayed by the total fees label.</p>
<pre><code> public partial class Automotive_Shop : Form
{
const int salesTax = (6 / 100);
// prices for services
const int
oilChange = 26,
lubeJob = 18,
radiatorFlush = 30,
transissionFlush = 80,
inspection = 15,
mufflerReplacement = 100,
tireRotation = 20;
int total = 0;
public Automotive_Shop()
{
InitializeComponent();
}
private int OilLubeCharges()
{
if (oilChangeCheckBox.Checked == true)
{
total += oilChange;
}
if (lubeJobCheckBox.Checked == true)
{
total += lubeJob;
}
return total;
}
private void calculateButton_Click(object sender, EventArgs e)
{
totalFeesOutput.Text = OilLubeCharges().ToString("C");
}
private void exitButton_Click(object sender, EventArgs e)
{
// close application
this.Close();
}
}
</code></pre>
<p>The total should only be added once.</p>
<p>For instance:
if the "oil change" check box is selected,
then the total should be $26.</p>
<p>if the "lube job" check box is selected,
then the total should be $18.</p>
<p>And if both check boxes are selected,
then the total should be $44.</p>
<p>What ends up happening is that after the first check box is selected and the calculate button is clicked,
the "total" variable value continues to be added up.</p>
<p>So if i select "oil change" then click calculate, I get $26.
if I deselect it and select "lube job" the total doesn't equal $18, but $44.</p>

<p>I plotted this pairplot correlating only one features with all the others, how can i visualize it in a better way? I need to visualize 4 columns. In the official documentation of pairplot i can't find the option.</p>
<p>This is the df:
<a href="https://i.stack.imgur.com/6CB4L.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6CB4L.png" alt="This is the df" /></a></p>
<p>This is the part of the code:</p>
<pre><code>sns.pairplot(data=dftrain,
y_vars=['medv'],
x_vars=dftrain.columns[:-1])
</code></pre>
<p>This is the plot:
<a href="https://i.stack.imgur.com/F3aFh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/F3aFh.png" alt="This is the plot" /></a></p>

<p>I have this pattern thats composed by a quantity, a description and a price. Please not that the numbers and text can change everytime.</p>
<p>I need to use powershell to find and save the results. So far I got this... the pattern format is what is driving me crazy.</p>
<pre><code>$example_line = '3.00 CEBICHE CORVINA PI 26,805.00'
$pattern= '\d.\d\d \D'
$results = $example_line | Select-String $pattern -AllMatches
$results.Matches.Value
</code></pre>
<p>Any help is appreciated.</p>
<p>Thanks in advance !</p>
<p>EDIT. After seeing the answers Im trying regex to build the array.</p>
<p>I dont know why its not working for me... Im reading the txt file and I get results, but when I want to see the array I dont get any data in it.</p>
<p>So for example Im using this to save all matching lines into the array</p>
<blockquote>
<p>function pasar_a_word($archivo) {</p>
<pre><code>$content = Get-Content $root\UNB\FACTURA_FINAL\$archivo
$pattern = '(\d\.\d\d) (\D+?) (\d+,\d\d\d\.\d\d)'
Write-Host "FUNCION PASAR A WORD"
for($i = 0; $i -lt $content.Count; $i++){
$line = $content[$i]
$results = ([regex]::Matches($line, $pattern)).Value
}
Write-Host $results[1] }
</code></pre>
</blockquote>
