74,173,079 | <p>Trying to create a small program that takes in positive integers and converts it into reverse binary.</p>
<p>I've gotten this far:</p>
<pre><code>import math
integer = int(input())
while integer > 0:
x = integer % 2
print(int(math.floor(x)), end='')
integer = integer / 2
</code></pre>
<p>The problem with this is that the output would have unnecessary trailing 0s. For example, if the input is 12, the output would be 0011000......</p>
<p>I've tried the <strong>int</strong> function to remove floats, I also tried <strong>floor</strong> function to round up(albeit I might've done it wrong).</p>
<p>Could the problem be a lack of sentinel value?</p>

74,173,089 | <p>I am trying to set/read if a user is authenticated in my application. I have things working, but as I am learning more about RxJs, I am trying to refactor things to be more declarative.</p>
<p>My code samples below are 98% working. When I log in, I am seeing my logging statement in my service as expected with the correct value(s):</p>
<blockquote>
<p>console.log('setting auth status...', status); // true</p>
</blockquote>
<p>However, I'm not seeing the logging in my component:</p>
<blockquote>
<p>console.log('reading isAuthenticated$ status... ', response) <-- not seeing this when logging in</p>
</blockquote>
<p>If I refresh my page, I am seeing <code>Hello World</code> as expected. Since I am subscribing using the <code>async</code> pipe, I thought I would see the ui update without having to refresh.</p>
<p>If I log out, (click a button). I am seeing <em>all</em> logging statements as expected every time--even without refreshing.</p>
<blockquote>
<p>console.log('setting auth status...', status); // false</p>
</blockquote>
<blockquote>
<p>console.log('reading isAuthenticated$ status... ', response) // false</p>
</blockquote>
<p>This makes me think there is something wrong how I am emitting or reading <code>isAuthenticated$</code> observable.</p>
<p>How can I read the <code>isAuthenticated$</code> observable in my template without refreshing?</p>
<p>Here is my service:</p>
<pre><code>// auth.service.ts
export class AuthService {
private readonly baseURL = environment.baseURL;
private isAuthenticatedSubject = new BehaviorSubject<boolean>(
this.hasAccessToken()
);
isAuthenticated$ = this.isAuthenticatedSubject.asObservable();
...
signInWithEmailPassword(
emailPasswordCredentials: EmailPasswordCredentials
) {
return this.httpClient
.post<Response>(
`${this.baseURL}/v1/auth/signin`,
emailPasswordCredentials
)
.pipe(
map((authResponse) => {
// set auth cookie
this.setAuthenticatedStatus(true);
})
catchError((err) => {
return throwError(err);
})
);
}
...
setAuthenticatedStatus(status: boolean): void {
console.log('setting auth status...', status);
this.isAuthenticatedSubject.next(status); // true|false
}
signOut(): void {
this.router.navigate(['/signin']).then(() => {
this.setAuthenticatedStatus(false);
});
}
}
</code></pre>
<p>Here is what my component looks like:</p>
<pre><code>// app.component.ts
isAuthenticated$ = this.authService.isAuthenticated$.pipe(
tap((response) =>
console.log('reading isAuthenticated$ status... ', response)
),
catchError((err) => {
this.message = err;
return EMPTY;
})
);
</code></pre>
<p>Finally, here is my template:</p>
<pre><code><div *ngIf="isAuthenticated$ | async">Hello World!</div>
</code></pre>
<p><strong>EDIT</strong></p>
<p>I have a <code>login.component</code> that handles the email/password button click. It looks like this:</p>
<pre><code>signInWithEmailPassword(form: FormGroup): void {
if (form.invalid) {
return;
}
...
this.authService.signInWithEmailPassword(this.form.value).subscribe({
next: (response) => {
this.router.navigate(['/dashboard']).then(() => {
// this.authService.setAuthenticatedStatus(true); // This doesn't seem to impact anything
});
},
error: (err) => {
this.handleHttpError(err);
},
complete: () => {
//...
},
});
}
</code></pre>
<p>I thought that by setting that in my <code>login.component</code> I could update that subject. It all works after I refresh the page. The nav shows...but if I just login... it's like I'm not "watching" on my <code>app.component</code> that observable or something.</p>
<p><strong>EDIT/UPDATE</strong></p>
<p>I have tried to set up a <a href="https://stackblitz.com/edit/angular-ivy-jhshqi?file=src%2Fapp%2Frouter%2Froutes.ts,src%2Fapp%2Fauthentication%2Fauth.service.ts,src%2Fapp%2Fapp.component.ts" rel="nofollow noreferrer">stackblitz</a> to help illustrate what I'm running into. I am not sure how to mock the auth part to return a dummy response, but hopefully this will help.</p>

74,173,090 | <p>I need to have in array with lat/lon points like that:</p>
<pre><code>/*
var polylinePoints = [

[37.780704, -122.403945],
[37.780012, -122.404827]
];
*/
</code></pre>
<p><strong>But I need first to sort it by third parameter which is timestamp?
How to do that? I know how to do that in PHP but not in JS</strong></p>
<pre><code>var polylineTimestamp = [
[37.781814, -122.404740, 1666543938],
[37.781719, -122.404637, 1666543938],
[37.781489, -122.404949, 1666543938],
[37.780704, -122.403945, 1666543938],
[37.780012, -122.404827, 1666543938]
];
</code></pre>
<p>Then I need to delete (trim) sorted array (delete timestamp) to have something like polylinePoints.</p>

char letter(int grade);
int main()

74,173,174 | <p>For an assignement I have to write a Greedy Algorithm using a recursive function, but I can't seem to figure out how to do this.</p>
<p>The assignement is to make a route to go from one city to another, each time going to the city with the lowest distance between them, but no visit cities multiple times.</p>
<p>For now I have the following code, which is of course far from done as it doesnt even have any recursion and simply doesn't give the right result. I wouldn't be surprised if this code is not even slightly right. The result I get is [1,2,1,1], meaning the route would be from city 0 to 1, to 2, to 1, to 1. The answer should be [1, 2, 3].</p>
<p>I've been trying this code for way too long now and I just can't seem to figure it out. I get the idea of what I have to do: take the index of the lowest distance, check if that index is already in list v, if it is, take the second lowest distance and check again. But I can't figure out how to put this into code and include recursion.</p>
<p>Is anyone able to give me any tips to help me along or link me an example code?</p>
<p>PS I am not allowed to use any import functions, this assignement is for a relatively simple (though not simple for me) programming course at my university</p>
<pre><code>v = []
def append_list_with_nearest_unvisited(visited, distances):
city = 0
for n in range(len(distances)):
if city in v:
i = min(j for j in distances[n] if j > 0) #take lowest distance
h = min(k for k in distances[n] if k > i) #take second lowest distance because the true lowest distance is a visited city
city = distances[n].index(h) #city visited is the index of the lowest distance
v.append(city)
else:
i = min(j for j in distances[n] if j > 0) #take lowest distance
city = distances[n].index(i)
v.append(city)
print(v)
append_list_with_nearest_unvisited(v, [[0,2,3,4],[2,0,4,5],[3,4,0,6],[4,5,6,0]])

74,173,218 | <p>I am using vue js with vuetify. Came across an interesting scenario .
So i have three options (radio-buttons)</p>
<ul>
<li>Left</li>
<li>Center</li>
<li>Right</li>
</ul>
<p>And i have a v-text-field with a certain text as value and readonly .
Now i want to change the position of that text inside v-text-field when option is changed/selected.</p>
<p>So for instance, upon option 1(left) text should be at moved at left inside v-text-field. Upon option 2(centre) text should be moved at center. And goes on.</p>
<p>Any suggestions for that. Also guide if you have a better approach</p>

74,173,240 | <p>I'm working on a small project where I would like to visualize a DataFrame using <code>python</code> + <code>streamlit</code>. The user should be able to filter on three different columns where the options which should be available depend on each other.
A minimal example is given by the DataFrame below.</p>
<pre><code>import pandas as pd
df = pd.DataFrame(
{
"continent": ["Asia"] * 2 + ["Europe"] * 2 + ["North America"] * 2,
"country": ["China", "Japan"]
+ ["United Kingdom", "France"]
+ ["United States", "Canada"],
"language": ["Chinese", "Japanese"]
+ ["English", "French"]
+ ["English", "English"],
}
)
</code></pre>
<p>The user should be able to select <code>continent</code>, <code>country</code> and <code>language</code>.</p>
<p>Example 1: The user selects <code>continent = North America</code> which should reduce the options for the country menu to <code>United States</code> and <code>Canada</code> and the languages to <code>English</code>.
As a next step, if the user switches from <code>continent = America</code> to <code>continent = Europe</code>, the second menu should reduce to the countries in Europe and the languages spoken in these countries.</p>
<p>Example 2: The user starts by selection <code>language = English</code>. As as a result the options for <code>continent</code> reduce to <code>North America</code> and <code>Europe</code> since the countries in which English is spoken are <code>Canada</code>, the <code>United States</code> and the <code>United Kingdom</code>.</p>
<p>The problem is, that the values depend on each other in a non-linear fashion. I've tried to solve this problem with <code>streamlit</code> and <code>callback</code> but from reading other questions my impression is that <code>streamlit</code> is not designed for complex dependencies.</p>
<p>I've not yet worked with <code>Dash</code>. Before I start working on this by copy-pasting code from the internet my question is whether it is possible to build these complex dependencies with <code>dash</code>?</p>
<p><strong>Update</strong></p>
<p>I was able to build an MVP with <code>streamlit</code> using the code at the end. The dropdown menus are dynamic which is what I was looking for (Image 1). But because the dropdown options depend on the filtered DataFrame, once a selection was made, the only way back is to use the <code>Refresh Data</code> button which is not very user friendly (Image 2).</p>
<p>Image 1: Without selection

74,173,246 | <p>I'm working with investment fund data taken from Morningstar, which provides them at share class level. For people who did not have exposure to finance/funds, no need to dive into detail, but mine is a panel data structured as following:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Fund ID</th>
<th>Sec ID</th>
<th>Net Assets</th>
<th>Return</th>
<th>Rating</th>
</tr>
</thead>
<tbody>
<tr>
<td>A</td>
<td>A1</td>
<td>100</td>
<td>1%</td>
<td>4 stars</td>
</tr>
<tr>
<td>A</td>
<td>A2</td>
<td>200</td>
<td>1,2 %</td>
<td>4 stars</td>
</tr>
<tr>
<td>A</td>
<td>A3</td>
<td>150</td>
<td>0,5 %</td>
<td>3 stars</td>
</tr>
<tr>
<td>B</td>
<td>B1</td>
<td>50</td>
<td>1,1 %</td>
<td>2 stars</td>
</tr>
<tr>
<td>B</td>
<td>B2</td>
<td>120</td>
<td>0,75%</td>
<td>3 stars</td>
</tr>
<tr>
<td>C</td>
<td>C1</td>
<td>300</td>
<td>0,4%</td>
<td>5 stars</td>
</tr>
<tr>
<td>C</td>
<td>C2</td>
<td>500</td>
<td>0,55%</td>
<td>4 stars</td>
</tr>
</tbody>
</table>
</div>
<p>What I need to achieve is to aggregate data at Fund level (Fund ID), so that the fund size will be the sum of the net assets of the different share classes (Sec ID). The return and the star rating at fund level will be the weighted average of both variables (star rating rounded). I'm using R and my dataset is made of over 8000 share classes therefore it's essential to get an easily scalable solution.</p>
<p>i.e. Fund A return would be: (0.01 * 100 + 0.012 * 200 + 0.005 * 150) / (100 + 200 + 150) = 0,92%</p>
<p>Fund B rating would be (2 * 50 + 3 * 120) / (50 + 120) = 2.70 rounded to 3</p>
<p>Any help on how to achieve such a result? How could I apply that to a panel data (with daily observation over 3 months)?</p>

<pre><code>while read -r line
do read input
if [[ -z $input ]]; then
echo $line
done < file.txt

<p>or</p>
<pre><code>while read -r line
echo | echo $line

<p>with the error:</p>
<pre><code>sh: -c: line 3: syntax error near unexpected token `done'
sh: -c: line 3: `done < file.txt'
</code></pre>
<p>update: i forgot "fi" at the end of "if". however,</p>
<pre><code>while IFS= read -r line
do
read input
if [[ -z $input ]]
then
echo $line
fi
done < filename.txt
</code></pre>
<p>This time i am not getting any error, but it does not expect my enter input and does not print anything.</p>

74,173,313 | <p>I am trying to understand memory allocations in Julia and was playing around with the following test code:</p>
<pre><code>function f()
function test(x,y)
return x-1,y+1

x1=5
y1=6
function stest(num_runs,x,y)
for i in 1:num_runs
x,y=test(x,y)
end
return x,y
end
x1,y1=stest(10,x1,y1)
println(x1,' ',y1)
end
@time begin
f()
end
@time begin
f()
end
</code></pre>
<p>When I run it, I get the following outputs:</p>
<pre><code> -5 16
0.027611 seconds (20.59 k allocations: 1.039 MiB, 92.11% compilation time)
-5 16
0.000077 seconds (18 allocations: 496 bytes)
</code></pre>
<p>Why is there a memory allocation at all? And why is that so much the first time around? I have been reading through the docs but having trouble figuring it out.</p>

74,173,375 | <p>I am using C to work on a program that manages structs in a binary file.</p>
<p>I am having issues with my deleteData()function.</p>
<p>The method gets file name from user, validates file name, asks for record id to be deleted, then it copies the records except the one to be deleted from a file it is reading to a temp file.</p>
<p>The function should then close files, delete old file, and rename new file by the old file's name.</p>
<p>Everything appears to work except I can't open the new renamed file. I have checked the outcome in every step and it all appears to be ok.</p>
<p>Furthermore, when I look in my folder, I can see the renamed file and from it's byte size I can tell that a record has indeed been deleted.</p>
<p>But I can't open the file.</p>
<p>Please see my code below. I am working on a MAC, I have saved the folder that includes the code on my desktop. I am new to programming so any feedback or advise would be greatly appreciated.</p>

74,173,402 | <p>I use MongoDB to store user data. The user id goes incrementally, such as 1, 2, 3, 4 etc when new user register.</p>
<p>I have the following code to generate the user id. "users" is the name of the collection where I store the user data.</p>
<pre><code>// generate new user id
let uid;
const collections = await db.listCollections().toArray();
const collectionNames = collections.map(collection => collection.name);
if(collectionNames.indexOf("users") == -1){
uid = 1;
}
else{
const newest_user = await db.collection("users").find({}).sort({"_id":-1}).limit(1).toArray();
uid = newest_user[0]["_id"] + 1;
}
user._id = uid;
// add and save user
db.collection("users").insertOne(user).catch((error)=>{
throw error;
});
</code></pre>
<p>One concern I have now is that when two users make a request to register at the same time, they will get same maximum user id, and create the same new user id. One way to prevent it is using a locked thread. But, I think Node.js and Next.js doesn't support multi-thread.
What are some alternatives I have to solve this problem?</p>
<p>In addition, _id will be the field for uid. Will it make a difference since _id can't be duplicated.</p>

74,173,429 | <p>is there a way to plot a bar graph in <code>ggplot</code> and group the bars accordingly using a horizontal line with label. It should look something like in the image below but for multiple groups and bars in one single graph only.</p>
<p>For context, I'm planning to group three bars for each horizontal label in one graph. For example, the first 3 bars would represent my control, the next three bars would be for treatment 1, the next three would be for treatment 2, and so on.</p>
<p>Let me know if you have a template for making such a graph. Thanks!</p>

<p>Does someone please have an idea of what my be the problem?</p>

<pre><code>const Discord = require("discord.js");
const client = new Discord.Client();
var prefix = "!";
require('events').EventEmitter.defaultMaxListeners = 99;
client.login("XXX");
client.on("ready", () => {
console.log("I'm on!"); // this effectively prints in console when node starts
});
</code></pre>

74,173,461 | <p>I want to know if a method on a class gets redefined.</p>
<p>use case: in version 1 of ruby-clock, defining a method on an object was part of the API. In version 2, doing so will break behavior, and a different API should be used.</p>
<p>what I ended up doing: <a href="https://github.com/jjb/ruby-clock/pull/28/files" rel="nofollow noreferrer">https://github.com/jjb/ruby-clock/pull/28/files</a></p>
<hr />
<p>The best would be if I could use some sort of metaprogramming to notice when it happens.:</p>
<pre class="lang-rb prettyprint-override"><code># this is example code which does not work
class MyClass
def my_method
puts "hello"
end
# this is not real! it's an example of what i hope is somehow possible
def self.method_defined(m, *args, &block)
if :my_method == m
raise "you should not redefine my_method!"
end
end
end
</code></pre>
<p>Also acceptable would be if I could check back later and see if it has changed.</p>
<pre class="lang-rb prettyprint-override"><code># this is example code which does not work
class MyClass
def my_method
puts "hello"
end
@@my_method_object_id = get_method_object_id(:my_method)
end
# later, when app initialization is done, check if the user redefined the method
# this is not real! it's an example of what i hope is somehow possible
def self.method_defined(m, *args, &block)
if MyClass.get_method_object_id(:my_method) != MyClass.my_method_object_id
raise "you should not redefine my_method!"
end
end
</code></pre>
<p>n.b. that <code>MyClass.method(:my_method)</code> is a real thing in ruby, but it always produces a new object.</p>

74,173,462 | <p>I would to parse a phone field in a pandas dataframe. My phone field is named <em><strong>Phone</strong></em> and my country code field <em><strong>CountryCode</strong></em>.</p>
<p>It works but only when all the phones are filled:</p>
<pre><code>df['Test phone'] = df.apply(lambda x:phonenumbers.parse(str(x['Phone']), str(x['CountryCode'])), axis='columns')
</code></pre>
<p>OK, but how to do it only if the phone, or even the country code, are filled?
I tried a lot of <em><strong>if/else</strong></em> syntaxes in the <em><strong>lambda</strong></em> function, without success.</p>
<p>Amazing, I also tried doing it in a <em><strong>df.loc</strong></em>, it does not work neither...</p>
<p>Please, have you an idea?</p>
<p>THX</p>

74,173,467 | <p>I have 4 points marked in an equirectangular image. [Red dots]</p>
<p><a href="https://i.stack.imgur.com/sDS4R.png" rel="noreferrer"><img src="https://i.stack.imgur.com/sDS4R.png" alt="enter image description here" /></a></p>
<p>I also have the 4 corresponding points marked in an overhead image [ Red dots ]</p>
<p><a href="https://i.stack.imgur.com/ilgmn.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ilgmn.png" alt="enter image description here" /></a></p>
<p>How do I calculate where on the overhead image the camera was positioned?</p>
<p>So far I see there are 4 rays (<code>R1</code>, <code>R2</code>, <code>R3</code>, <code>R4</code>) extending from the unknown camera center <code>C = (Cx, Cy, Cz)</code> through the points in the equirectangular image and ending at the pixel coordinates of the overhead image (<code>P1</code>, <code>P2</code>, <code>P3</code>, <code>P4</code>). So 4 vector equations of the form:</p>
<pre><code>[Cx, Cy, Cz] + [Rx, Ry, Rz]*t = [x, y, 0]
</code></pre>
<p>for each correspondence. So</p>
<pre><code>C + R1*t1 = P1 = [x1, y1, 0]
C + R2*t2 = P2 = [x2, y2, 0]
C + R3*t3 = P3 = [x3, y3, 0]
C + R4*t4 = P4 = [x4, y4, 0]
</code></pre>
<p>So 7 unknowns and 12 equations? This was my attempt but doesn't seem to give a reasonable answer:</p>
<pre><code>import numpy as np

74,173,484 | <p>I need to update some fields and do some login on <code>task</code> entity.
Actually based on my requirement, when the task <code>record status</code> change to <code>complete</code>(user click on <code>Mark as Complete</code>.), my logic must start.
For this reason and because of no <code>event</code> like <code>complete</code> in <code>task messages</code>, I check status of the record in <code>update message</code>.
I would like to this via <code>CRM Plugin</code>.
To achieve this I use <code>PostEntityImages</code> of task record.
I check the status of <code>PostEntityImages</code> in the code and then do my logic.
This is what happening :</p>
<pre><code> if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
currentTask = (Entity)context.InputParameters["Target"];
if (currentTask.LogicalName == "task")
{
afterUpdateTask = (Entity)context.PostEntityImages["updatedTask"];
beforeUpdateTask = (Entity)context.PreEntityImages["updatedTask"];
if (afterUpdateTask.Contains("statuscode"))
{
int statuscode = ((OptionSetValue)afterUpdateTask["statuscode"]).Value;
if (statuscode == 5)
{
</code></pre>
<p>As you see I also get the <code>PreEntityImages</code> as well.
After last if, the logic starts and some fields update; the fields of <code>PostEntityImages</code>(afterUpdateTask ).
But <code>CRM</code> returns :</p>
<pre><code>The object cannot be updated because it is read-only. If you contact support, please provide the technical details.
</code></pre>
<p>It seems CRM does not talk much off !
I also tried this with <code>PreEntityImages</code>(beforeUpdateTask), but it does not work for me.
Because it updates the fields in <code>task entity</code>, but does not change the status of record to <code>complete</code>, however in my scenario I need the <code>modifiedon</code> and <code>statuscode</code> fields of PostEntityImages.
Also tried with <code>currentTask</code> that is <code>(Entity)context.InputParameters["Target"]</code>, but it just change the <code>stauts</code> of record to <code>complete</code> without running my logic.</p>
<p>What should I do to update a task record after it change to complete?
Is it possible to do this via Plugin?</p>

74,173,541 | <p>I tried to implement a multithreading cache in C++ 11. I tried to create threads in the main function and passed the putcache function and getcache function as parameter. And I passed class object c1 to the two functions as parameters. However, I found that the complier gave me a error like this: <code>In template: no matching constructor for initialization of '_Gp' (aka 'tuple<unique_ptr<std::__thread_struct>, void (*)(LRUCache), LRUCache>')</code>
Here is my code:</p>
<pre><code>#include <iostream>
#include <unordered_map>
#include <thread>
#include <chrono>
#include <mutex>
using namespace std;
class LRUCache {
public:
class Node {
public:
int key,val;
Node* left,*right;
Node(int _key,int _val):key(_key),val(_val),left(NULL),right(NULL) {}
}*L,*R;
unordered_map<int,Node*> m;
int n;
mutex mtx;
condition_variable cv;
void insert(Node* node)
{

L->right=node;
node->right=next;
node->left=L;
next->left=node;
}
void erase(Node* node) {

}
LRUCache(int capacity) {
n=capacity;
L=new Node(-1,-1),R=new Node(-1,-1);

R->left=L;
}
int get(int key) {
if(m.count(key)==0) return -1;
mtx.lock();
Node* node=m[key];
erase(node);
insert(node);
return node->val;
mtx.unlock();
}
void put(int key, int value) {
mtx.lock();

74,173,628 | <p>I want to write a <code>pipeline</code> function which takes an abritrary number of functions and forwards the input of the first to the second and so on up until the last. The output of <code>pipeline</code> is a <code>Callable</code>. The input of that <code>Callable</code> matches the first function given to <code>pipeline</code>. The output matches the last function given to <code>pipeline</code>. I would like to add type annotations to <code>pipeline</code>. This is what I came up with so far:</p>
<pre class="lang-py prettyprint-override"><code>from typing import TypeVar
from typing_extensions import ParamSpec, Concatenate
P = ParamSpec("P")
Output = TypeVar("Output")
def pipeline(func: Callable[Concatenate[P], T], *funcs: Callable[..., Output]) -> Callable[Concatenate[P], Output]:
...
</code></pre>
<p>But this gives a <code>Union</code> of all <code>Output</code> types of <code>*funcs</code>. Example:</p>
<pre class="lang-py prettyprint-override"><code>def double(x: int) -> Tuple[int, int]:
return x, x*2
def add(x: int, y: int) -> int:
return x + y
def to_string(x: int) -> str:
return str(x)
new_func = pipeline(add, double, add, to_string)
</code></pre>
<p>With the type annotation shown above the type / signature of <code>new_func</code> results in</p>
<pre class="lang-py prettyprint-override"><code>new_func: (x: int, y: int) -> (Tuple[int, int] | int | str)
</code></pre>
<p>It's quite clear that pipeline should have the following signature:</p>
<pre class="lang-py prettyprint-override"><code>new_func: (x: int, y: int) -> str
</code></pre>
<p>Is there a way to achieve this with type annotations?</p>

74,173,630 | <p>I am displaying multiple charts in a Grid. Every chart fetches different data from my server.
When I resize the window the data is fetched again and the chart renders from scratch. I want to avoid the re-fetching.</p>
<p>I use <code>highcharts</code> as chart library, <code>useQuery</code> to fetch data (tried with <code>useEffect</code> hook aswell) and a Grid from <code>material UI</code>.</p>
<p>Update to my original question:</p>
<p>I have wrapped my <code>app.js</code> in a dashboard layout. This layout uses a MUI <code>styled</code> component. I figured when I use a normal <code>div</code> instead, the re-fetching stops. But also the <code>Outlet</code> is not displayed correctly as it's hidden behind the sidebar.</p>
<p>Here are my Components:
dashboard-layout.js</p>
<pre><code>import { useState } from 'react';
import { DashboardNavbar } from './dashboard-navbar';
import { DashboardSidebar } from './dashboard-sidebar';
import { DashboardContent } from './dashboard-content';
import { DrawerContextProvider } from "../../contexts/drawer-context";
export const DashboardLayout = (props) => {
const [isSidebarOpen, setSidebarOpen] = useState(true);
return (
<>
<DrawerContextProvider>
<DashboardContent/>
<DashboardNavbar onSidebarOpen={() => setSidebarOpen(true)} />
<DashboardSidebar
onClose={() => setSidebarOpen(false)}
open={isSidebarOpen}
/>
</DrawerContextProvider>
</>
);
};
</code></pre>
<p>DashboardContent.js</p>
<pre><code>import { Box, useMediaQuery } from '@mui/material';
import { useTheme, styled } from '@mui/material/styles';
import { Outlet } from 'react-router-dom';
import { useDrawerContext } from "../../contexts/drawer-context";
import DashboardFooter from './dashboard-footer';
export const DashboardContent = () => {
const { isOpened } = useDrawerContext();
const theme = useTheme();
const isLargeScreen = useMediaQuery(theme.breakpoints.up("md"));
const DashboardContentRoot = styled('div')(({ theme }) => ({
display: 'flex',
flex: '1 1 auto',
maxWidth: '100%',
paddingTop: 64,
paddingLeft: isLargeScreen && isOpened ? 280 : 0
}));
return (
<DashboardContentRoot >
<Box
sx={{
display: 'flex',
flex: '1 1 auto',
flexDirection: 'column',
width: '100%',
px: isLargeScreen ? 1.5 : 1,
py: isLargeScreen ? 1.5 : 1
}}
>
<Outlet/>
<DashboardFooter />
</Box>
</DashboardContentRoot>
);
};
</code></pre>
<p>The problem with re-rendering and therefore re-fetching persists even when I empty <code>DashboardContentRoot</code> like so:</p>
<pre><code> const DashboardContentRoot = styled('div')(({ theme }) => ({
}));
</code></pre>
<p>but when I use <code>div</code> instead, no refetching happens:</p>
<pre><code><div>
<Box
sx={{
display: 'flex',
flex: '1 1 auto',
flexDirection: 'column',
width: '100%',
px: isLargeScreen ? 1.5 : 1,
py: isLargeScreen ? 1.5 : 1
}}
>
<Outlet/>
<DashboardFooter />
</Box>
</div>
</code></pre>
<hr />
<p>Components for my original question:</p>
<p>Chart.js</p>
<pre><code>import React from "react";
import { useQuery } from "react-query";
import '../HighchartsStyle.css';
async function fetchData(){
const data = await (
await fetch("myserver/data")
).json()
console.log("fetching again")
return data
}
export default function Chart1(){
const {status, data, error, isLoading } = useQuery('data', fetchData);
return (
<div>
hohoho
</div>
);
}
</code></pre>
<p>Grid.js</p>
<pre><code>import React from "react";
import { Chart1 } from "../components/charts/Chart1";
export default function ChartOverviewView() {
return (
<div >
<Chart1 />
</div>
);
}
</code></pre>
<p><code>fetching again</code> is displayed every time I resize the window. I want to fetch the data once. Save it temporarily and use the already-fetched data every time I have to rerender the chart again.</p>
<p>What is the best practice to do so?</p>
<p>Thanks!</p>

74,173,686 | <p>Shortly, when I try to use useState with useContext in one of my components, all pages just disappear. UseState in some reason block my Routers and I have no idea why... Can you tell me where is my mistake?</p>
<p>Some code below:
Index.js</p>
<pre><code>export default function App() {
const [value, setValue] = useState(false) -----> here I set the state
return (
<BrowserRouter>
<UserContext.Provider value={{ value, setValue }}>
<Routes>
<Route path='/' element={<Layout />}>
<Route index element={<Home />} />
<Route path='Home' element={<Home />} />
<Route path='Menu' element={<Menu />} />
<Route path='Story' element={<Story />} />
<Route path='Coffee' element={<Coffee />} />
<Route path='Cart' element={<Cart />} />
</Route>
</Routes>
</UserContext.Provider>
</BrowserRouter>
)
}
// ReactDOM.render(<App />, document.getElementById("root"))
const root = ReactDOM.createRoot(document.getElementById("root"))
root.render(<App />)
</code></pre>
<p>Buy.js component</p>
<pre><code>import { useState } from "react"
import { useContext } from "react"
import { UserContext } from "../../UserContext"
const Buy = () => {
const [buttonText, setButtonText] = useState("Add to cart")
const [isActive, setIsActive] = useState(false)
// const [value, setValue] = useContext(UserContext) --> after I declare state everything disappears
const addToCart = () => {
setIsActive((current) => !current)
// setValue(true)
if (isActive) {
setButtonText("Add to cart")
}
}
return (
<div>
<button
class='buy'
style={{
fontSize: isActive ? "0.8rem" : "1rem",
color: isActive ? "lightgray" : "white",
}}
onClick={() => {
addToCart()
}}
>
{buttonText}
</button>
</div>
)
}
export default Buy
</code></pre>
<p>UserContext.js</p>
<pre><code>import { createContext } from "react"
export const UserContext = createContext(null)
</code></pre>
<p>Actually, I need this Context only for routes "Coffee" and "Cart", but if I wrap only this 2 routes will be the same problem and all is disappear. Should I maybe use Context in my Layout.jsx instead of Index.js? Thank you.</p>
<pre><code>const Layout = () => {
return (
<>
<Navbar />
<Outlet />
<Footer/>
</>
);
};
export default Layout;
</code></pre>

<p>As you can see, some numbers in the header have the red color. How can I color the WHOLE column with red if the respective <code><th></code> is also red?</p>
<p>I was thinking to use js, and it would look something like this (just an idea, not the actual code lol):</p>
<pre><code>if(header(current_td).hasProperty('color: red')) {
apply(color.red);
}
</code></pre>
<p>How can I do this?</p>

74,173,781 | <p>I am new to Java Programming and was trying the string examples, found that the below code, though prints the output also prints the exception. Please let know why is it throwing an ArrayIndexOutOfBoundsException. The length of commaSeparatedString is 37. How to limit it to the stringArrayLength than the commaSeparatedString length ?</p>
<pre><code>package stringMethods;
public class stringMethods {
public static void main(String args[]) {
String text = "Hello";
//System.out.println(text.charAt(2));
//System.out.println(text.equalsIgnoreCase("hello"));
//System.out.println(text.contains("lo"));
String commaSeparatedString = "This, is, a, comma, separated, string";
String[] stringArray = commaSeparatedString.split(",");
for(int i=0; i < commaSeparatedString.length(); i++){
System.out.println(stringArray[i]);
}
}
}
</code></pre>
<p>Output :</p>

74,173,786 | <p>I have a hash in ruby like below:</p>

<p>I want to generate a bash command which can generate a json file using this json string:</p>

74,173,822 | <p>I have a Kafka Producer which is producing messages and couple of consumers(group) who are trying to consume them. I created a topic which has 3 partitions and started 2 consumers with <code>--group</code> parameter. The issue I am facing is that all the messages are being routed to a single consumer. Following are the commands which I ran to create the topic, start the producer and consumer.</p>
<p>To create the kafka topic</p>
<p><code>kafka-topics.sh --bootstrap-server localhost:9092 --create --topic logs --partitions 3</code></p>

Topic: logs Partition: 1 Leader: 0 Replicas: 0 Isr: 0
Topic: logs Partition: 2 Leader: 0 Replicas: 0 Isr: 0
</code></pre>
<p>Started the producer using the below command</p>
<p><code>kafka-console-producer.sh --bootstrap-server localhost:9092 --topic logs</code></p>
<p>and the both the consumers using this</p>
<p><code>kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic logs --group my_group</code></p>
<p>When I try to describe the group I am getting the following error.</p>

74,173,861 | <p>I'm using react router dom v6. If I write routes like this:</p>
<pre><code> <Routes>
<Route path='/posts' element={<Posts/>}/>
<Route path='/posts/:id' element={<PostDetails/>}/>
<Route path='/about' element={<About/>}/>
<Route path='/' element={<Main/>}/>
<Route path='*' element={<NotFound/>}/>
</Routes>
</code></pre>
<p>it's okay, useParams returning { id: number } in the PostDetails component.</p>
<p>However If I write routes like the following:</p>
<pre><code> <Routes>
{routes.map(({path, component}) =>
<Route path={path} element={component()}/>
)}
</Routes>
</code></pre>
<p>useParams returns empty object. Why this happening?</p>
<p>PS: <code>routes</code> is an array of objects containing path & component values. The actual <code>routes</code> value is:</p>
<pre><code>export const routes = [
{
path: '/',
component: Main,
},
{
path: '/about',
component: About,
},
{
path: '/posts',
component: Posts,
},
{
path: '/posts/:id',
component: PostDetails,
},
]

74,173,918 | <p>Hey all I am trying to add to a list of <code>map<String, String></code> using the code below:</p>
<pre><code>@NonNull
public static List<Map<String, String>> mysqlSelect(@NonNull String select, String where) {
Map<String, String> info = new HashMap<String,String>();
List<Map<String, String>> list = new ArrayList<>();
int selectCnt = select.replaceAll("[^,]","").length();
final boolean[] b = {true};
new Thread(new Runnable() {
@Override
public void run(){
try (Connection connection = DriverManager.getConnection(URL, USER, PASSWORD)) {
String sql = "SELECT fb_firstname, fb_lastname, fb_id FROM fbuser";
PreparedStatement statement = connection.prepareStatement(sql);
ResultSet resultSet = statement.executeQuery();
while (resultSet.next()) {
info.put("name", resultSet.getString("fb_firstname"));
info.put("address", resultSet.getString("fb_lastname"));
info.put("phone_number", resultSet.getString("fb_id"));
list.add(info);
}
b[0] = false;
} catch (Exception e) {
Log.e("InfoAsyncTask", "Error reading school information", e);
b[0] = false;
}
}
}).start();
while (b[0]) { }
return list; //result.get("name")
}
</code></pre>
<p>As it loops in the <code>while () {..</code> part it populates the list with the needed 3 string values. However, as it does loop over and over again it seems to populate all the previous values to what was last read instead of having new data each time?</p>
<p>Example:</p>
<p>1st loop:</p>
<pre><code>name: bob barker
address: something
phone-number = 4235421212
</code></pre>
<p>2nd loop:</p>
<pre><code>name: steve jobs
address: something again
phone-number = 8546521111
</code></pre>
<p>at this point the 1st loop data turns into</p>
<p>1st loop:</p>
<pre><code>name: steve jobs
address: something again
phone-number = 8546521111
</code></pre>
<p>2nd loop:</p>
<pre><code>name: steve jobs
address: something again
phone-number = 8546521111
</code></pre>
<p>So, what am I missing here?</p>
<p><strong>UPDATE 1</strong></p>
<p>Originally I have the following:</p>
<pre><code>@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new InfoAsyncTask().execute();
}
@SuppressLint("StaticFieldLeak")
public class InfoAsyncTask extends AsyncTask<Void, Void, Map<String, String>> {
@Override
protected Map<String, String> doInBackground(Void... voids) {
Map<String, String> info = new HashMap<>();
try (Connection connection = DriverManager.getConnection(URL, USER, PASSWORD)) {
String sql = "SELECT fb_firstname, fb_lastname, fb_id FROM fbuser LIMIT 1";
PreparedStatement statement = connection.prepareStatement(sql);
ResultSet resultSet = statement.executeQuery();
if (resultSet.next()) {
info.put("name", resultSet.getString("fb_firstname"));
info.put("address", resultSet.getString("fb_lastname"));
info.put("phone_number", resultSet.getString("fb_id"));
}
} catch (Exception e) {
Log.e("InfoAsyncTask", "Error reading school information", e);
}
return info;
}
@Override
protected void onPostExecute(Map<String, String> result) {
if (!result.isEmpty()) {
TextView textViewName = findViewById(R.id.textViewName);
TextView textViewAddress = findViewById(R.id.textViewAddress);
TextView textViewPhoneNumber = findViewById(R.id.textViewPhone);
textViewName.setText(result.get("name"));
textViewAddress.setText(result.get("address"));
textViewPhoneNumber.setText(result.get("phone_number"));
}
}
}
</code></pre>
<p>But I wanted to put it into its own class file and call it from the onCreate.</p>

74,174,119 | <p>I have a controller class for the health of a GameObject. It is not a MonoBehavior but it will be used by MonoBehavior objects.</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using UnityEngine;
[Serializable]
public class HealthController{
[SerializeField]
private int max_health;
private int health;
public HealthController {
this.health = this.max_health; // this doesnt work because its called before serialisation
}
}
</code></pre>
<p>so I want to be able to set the maximum health in the unity editor: thats why <code>max_health</code> is a SerializeField. But now i also want the variable <code>health</code> initally to be set to the the maximum health without introducing a second SerializeField for it. Thats why I tried to put the line <code>this.health = this.max_health</code> to the constructor: but this doesn#t work because the constructor seems to be called before the serialisation.</p>
<p>The only solution i could think of is adding a <code>public void Initialize()</code> instead of the contructor to the HealthController and then explicitly calling this in the Start() method of the Monobehavior owning this controller.</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using UnityEngine;
[Serializable]
public class HealthController{
[SerializeField]
private int max_health;
private int health;
public void Initialize() {
this.health = this.max_health;
}
}
public class Player : MonoBehaviour
{
public HealthController health;
public void Start() {
health.Initialize();
}
}
</code></pre>
<p>But this seems too complicated to me: Is there a better solution on how to do this?</p>

74,174,246 | <p>I have a folder with files like:</p>
<pre><code>pe1_file1.txt
pe1_file2.txt
px1_file3.txt
px1_file4.txt etc
every file has lines such:
1123343 34 SDSD XV34 nameofdatabase 34 45455 4545
1145343 33 SD34 XT45 nameofdatabase 34 45455 4545
</code></pre>
<p>I would like to parse all the files of that folder (actually there are a bunch of folders) and build up a single text file that includes all the lines of all those text files that comply with a particular condition. The resulting file should only contain the first 5 values (up to nameofdatabase) AND the 3 first letters of the name of the file.</p>
<p>I tend to use the following code modified:
The following passes all the filtered lines and with all the values. I want to omit the last three numbers and add "pe1" or "px2" as first value.</p>
<pre><code>for FILE in files/*.txt;
do
firstchar=${FILE:0:4}
# how do I modify the nest line in order to add $firstchar ("pe1") and $1,$2,$3,$4,$5,$6 ???
awk '$3=="SDSD"&&$4=="cardatabase"' $FILE.txt >> TOTAL.txt
done

74,174,252 | <p>I am building a website with a container and a background image but is de client is a mobile device want to prevent the client from loading this image.
For bigger screens would I like to use +-5 images with a different resolution for every device width. But I don't find a way to use this
<code><img style="width: 100%;" src="./img/normal.png" srcset=" img/lowres.png 700w, img/normal.jpg 900w, img/highres.jpg 1100w" alt="test img"></code></p>
<p>in CSS, now I am using an regular high res image. (But it shouldn't load on mobile and be an appropriate size for every desktop)</p>
<pre><code>max-width: 2560px;
background-image: url("../img/test_image_2.jpg");
background-repeat: no-repeat;
background-attachment: fixed;}```
</code></pre>

74,174,258 | <p>What's the best approach to store multiple images in database?</p>
<p>Upon browsing and searching for solution and approaches I found 2 options</p>
<p><code>first one is take the file name and concatenate and separate them using either comma or |</code>
but I'm having doubts since I think that's messy and would produce errors later in the system</p>
<p><code>second is I make another table for images and add foreign key (post_id) to know which post it belongs.</code></p>
<p>Any suggestion will be appreciated.</p>

74,174,310 | <p>I am writing a bash script that has 1) number of lines in a file matching a pattern and 2) total lines in a file.</p>
<p>a) To get the number of lines in a file within a directory that had a specific pattern I used grep -c "pattern" f*</p>
<p>b) For overall line count in each file within the directory I used
wc -l f*</p>
<p>I am trying to divide the output from 2 by 1. I have tried a for loop</p>
<pre><code>for i in $a
do
printf "%f\n" $(($b/$a)
echo i
done
</code></pre>
<p>but that returns an error <code>syntax error in expression (error token is "first file in directory")</code></p>
<p>I also have tried</p>
<pre><code>bc "$b/$a"
</code></pre>
<p>which does not work either</p>
<p>I am not sure if this is possible to do -- any advice appreciated. thanks!</p>
<p>Sample: grep -c *f generates a list like this</p>
<pre><code>myfile1 500
myfile2 0
myfile3 14
myfile4 18
</code></pre>
<p>and wc -l *f generates a list like this:</p>
<pre><code>myfile1 500
myfile2 500
myfile3 500
myfile4 238
</code></pre>
<p>I want my output to be the outcome of output for grep/wc divided so for example</p>
<pre><code>myfile1 1
myfile2 0
myfile3 0.28
myfile4 0.07
</code></pre>

74,174,345 | <p>So I have a discord.js bot. And I want moderators to be able to run a slash command and upload an image to the bot's directory (folder on my Raspberry Pi, where my bot is hosted). So I made a command,</p>
<pre><code>const fs = require("fs");
const path = require("path");
const Discord = require("discord.js");
module.exports = {
data: new SlashCommandBuilder()
.setName("addimg")
.setDescription("Allows Moderators to add needed images.")
.addAttachmentOption((option) =>
option
.setName('image')
.setDescription('The image you want to add.')
.setRequired(true)
),
async execute(interaction, client) {
var image = interaction.options.getAttachment("image");
console.log(image)
if(path.parse(image.name).ext == ".png" || path.parse(image.name).ext == ".jpg"){
await fs.writeFileSync(`../../../imgs/${image.name}`, /*Data*/)
const embed = new Discord.EmbedBuilder()
.setTitle(`Image Added!`)
.setColor("000000")
.setDescription(`Check it out by using the /img command and choosing ${image}`)
interaction.reply({ embeds: [embed] });
}
else{
return interaction.reply({ embeds: [new Discord.EmbedBuilder()
.setTitle(`Failed to Add Image.`)
.setColor("000000")
.setDescription(`This format of image is not allowed. Try again with a .png or .jpg image.`)] })
}
}
}
</code></pre>
<p>But I don't know how/where to start with converting the Discord Attachment to binary (raw image data). And I know that the Discord Attachments have a .url which maybe should be used? But still I don't know how I would do that.</p>

return row * 0.856
elif year == "2019":
return row * 0.8566
else:
return row
final_udf = F.udf(lambda z: new_column(z), Double()) #How do I get - Double datatype here
res = res.withColumn("final_value", final_udf(F.col('value_column'), F.col('year')))
</code></pre>
<p>How can I write Double() in <code>final_udf</code>?
I see that for string we can use <code>StringType()</code>. But what can I do to return double type in the "final_value" column?</p>

74,174,413 | <p>I have the following data frame:</p>
<pre class="lang-py prettyprint-override"><code> df_test = pd.DataFrame({"f":['a', 'a', 'a', 'a', 'b', 'b', 'b', 'b'],
"d":['x', 'x', 'y', 'y', 'x', 'x', 'y', 'y'],
"low": [0,5,2,4,5,10,4,8],
"up": [5,10,4,6,10,15,8,12],
"z": [1,3,6,2,3,7,5,10]})
</code></pre>
<p>and what I first have to do is to convert the columns 'low', 'up' and 'z' to list for each (grouped by) 'f' and 'd'. so this is what I did:</p>
<pre class="lang-py prettyprint-override"><code> dff = df_test.groupby(['f','d'])[['low', 'up', 'z']].agg(list).reset_index()
</code></pre>
<p>and this is what I get:
<a href="https://i.stack.imgur.com/IXHtz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IXHtz.png" alt="enter image description here" /></a></p>
<p>Now I want to extract the last value from the lists in column 'up' and add it to the lists in column 'low'.
But this is unfortunately not working:</p>
<pre class="lang-py prettyprint-override"><code> dff['last'] = (dff['up'].apply(lambda x: x[-1])).tolist()
dff['new'] = dff['low'].append(dff['last'])
</code></pre>
<p>I get an error message "ValueError: cannot reindex from a duplicate axis".
The column 'new' should have these values:
[0,5,10], [2,4,6], [5,10,15], [4,8,12]</p>
<p>any help is very much appreciated!</p>

74,174,426 | <p>I am using temporarily a Mac (M1) with R but it runs only with one core. I am editing my question to include a reproducible example.
I would like to run functions with big data using multiple core.</p>
<p>this is the reproducible example:</p>
<pre class="lang-r prettyprint-override"><code>library(eulerr)
library(microbiome)
#devtools::install_github('microsud/microbiomeutilities')
library(microbiomeutilities)
data("zackular2014")
pseq <- zackular2014
table(meta(pseq)$DiseaseState, useNA = "always")
pseq.rel <- microbiome::transform(pseq, "compositional")
Make a list of DiseaseStates.
disease_states <- unique(as.character(meta(pseq.rel)$DiseaseState))
print(disease_states)
list_core <- c() # an empty object to store information
for (n in disease_states){ # for each variable n in DiseaseState
#print(paste0("Identifying Core Taxa for ", n))
ps.sub <- subset_samples(pseq.rel, DiseaseState == n) # Choose sample from DiseaseState by n
core_m <- core_members(ps.sub, # ps.sub is phyloseq selected with only samples from g
detection = 0.001, # 0.001 in atleast 90% samples
prevalence = 0.75)
print(paste0("No. of core taxa in ", n, " : ", length(core_m))) # print core taxa identified in each DiseaseState.
list_core[[n]] <- core_m
mycols <- c(nonCRC="#d6e2e9", CRC="#cbf3f0", H="#fcf5c7")
plot(venn(list_core),
fills = mycols)
</code></pre>
<p>I would like to run the first for loop using multiple cores but I don't know how to write the function including <code>mclapply</code>? thanks</p>

74,174,429 | <p>I have been been reading a lot of about SwiftUI architecture. I read about MVVM, TCA, MVC etc. I am writing an app, where I have to get data from the JSON API and display it on the screen. I am following Apple's code samples and here is what I am doing.</p>
<p>For that I created a NetworkModel.</p>
<pre><code>class NetworkModel {
func getPosts() async throws -> [Post] {
let (data, _) = try await URLSession.shared.data(from: URL(string: "https://jsonplaceholder.typicode.com/posts")!)
let posts = try JSONDecoder().decode([Post].self, from: data)
return posts
}
}
</code></pre>
<p><strong>Post.swift</strong></p>
<pre><code>struct Post: Decodable {
let id: Int
let title: String
let body: String
}
</code></pre>
<p><strong>PostListView</strong></p>
<pre><code>struct PostListView: View {
@State private var posts: [Post] = []
let networkModel = NetworkModel()
var body: some View {
List(posts, id: \.id) { post in
Text(post.title)
}.task {
do {
await networkModel.getPosts()
} catch {
print(error)
}
}
}
}
</code></pre>
<p>Everything works. Is this the right approach? I come from React background so in React if there is a component that is using state and that state will only be used for that component then we simply use private/local state.</p>
<p>I did not create any View Models etc for this app. Are VM's going to benefit me in someway?</p>

74,174,476 | <p>Given the following inputs that simulate a grid with the respective dimensions:</p>
<pre class="lang-py prettyprint-override"><code>totLines = int(input("Indicate the number os lines: "))
totColunms = int(input("Indicate the number of columns: "))
</code></pre>
<p>I want to check whether the input is valid or not (every digit must be between 0 and 20). The code should check each line of the grid and tell the user if the input is valid and if not ask for another input. The problem is that my code only checks the first digit of line1, the second digit of the line2, and so on. For instance, in a 3x3 grid, if I input the following numbers for line1 (separated by spaces) - 21 10 10 - the code is gonna tell me that the input is not valid, but if I put the incorrect digit in position 2 - 10 21 10 - the code is not gonna find any problem. I know the problem must be related to how I´m doing the loop but I can´t understand how to solve this. This is something easy to do but It´s my first time learning a programming language and I still have a lot to learn. Thanks!</p>
<pre class="lang-py prettyprint-override"><code>for lin in range (1, totLines+1):
print("Line", str(lin))
while True:
sMoves = input("Movement for this line: ")
listMoves = sMoves.split()
listMovesINT = list(map(int, listMoves))
if listMovesINT[lin-1] > 0 and listMovesINT[lin-1] <= 20:
break
else:
print ("Not a valid integer")
continue

74,174,604 | <p>Trying to take the odd positions from a vector and merge it with another vector in which I'm taking the even ones. (sorry if this is a bit wordy) This is what I've done so far</p>
<pre><code>Numbers = c(10,20,30,40,50,60,70,80,90,100,110,120)
x3=c(10,20,30,40,50,60,70,80,90)
MV <- function(x) { seq(1,length(x),2) }
MV(x3)
#[1] 1 3 5 7 9
MV2 <- function(x) { seq(1,length(x),1) }
MV2(x3)
MV3 <- function(x) { c(MV,MV2) }
MV3(x3,Numbers)
</code></pre>
<p>I got a result I don't understand. I feel like I'm missing something here.</p>
<p>I want the function to return the odd position from x3 and the even from Numbers.<br />
The goal would be</p>
<pre><code>#[1] 10 20 30 40 50 60 70 80 90 100 120
</code></pre>
<p>Sorry if confusing because Numbers and x3 are basically</p>

74,174,606 | <p>I have a python dataframe (df) created from a csv. I want to take every column name that contains 'PHONE' (or 'phone' or 'Phone') and change all their rows to be in the format of 5555555555. So:</p>
<p>(555) 555-5555 would be 5555555555,</p>
<p>555-555-5555 would be 5555555555,</p>
<p>and so on.</p>
<p>I tried the following, but got a syntax error. Hopefully I was at least kinda-sorta close:</p>
<pre><code>phone_format = df.loc[:, df.columns.str.contains('PHONE')]
for col in phone_format:
df['col'] = df.['col'].map(lambda x: x.replace('.', '').replace(' ', '').replace('-', '').replace('(', '').replace(')', ''))

74,174,622 | <p>Is there any way to convert the resulting days into INT without pandas? Or use the number of days to do "for" loop?</p>
<pre><code>from datetime import datetime, timedelta

print(date)

<p>Result:</p>
<pre><code>10 days, 0:00:00

<p>If I try for loop, it doesn't work.</p>
<pre><code>for days in range(date):

74,174,623 | <p>i am a little confused on how to generate with the ramdom function in python a list of length 10000 that randomly repeats the same 2 variables. Suppose once the randomly generated list is [a,b,a,a,a,a,b,b....] and the next time it renders [b,a,b,b,a,a,b,b...]. Can anyone help me on this one?</p>

74,174,637 | <p>Basic python learning:</p>
<p>I am asked to write a program that makes a list of 15 integer entries (size) the user inputs. For each input, the program should give the number of integers remaining to input. In the end, the program should list the 15 entries, and tell the user he is done.
With the code below, I get the list and the final report, but can't really figure out how to count down, print the remaining entries, and tell the user he is done.</p>
<pre><code>my_list = []
for _ in range(15):
try:
my_list.append(int(input('Enter size: ')))
except ValueError:
print('The provided value must be an integer')
print(my_list)

74,174,712 | <p>I found a formula for getting the angle between two 3D vectors (e.g. as shown in <a href="https://stackoverflow.com/a/12230083/6607497">https://stackoverflow.com/a/12230083/6607497</a>).</p>
<p>However when trying to implement it in PostScript I realized that PostScript lacks the arcus cosinus function needed to get the angle.</p>
<p>Why doesn't PostScript have that function and how would a work-around look like?</p>
<p>In <a href="https://en.wikipedia.org/wiki/Inverse_trigonometric_functions#Relationships_between_trigonometric_functions_and_inverse_trigonometric_functions" rel="nofollow noreferrer">Wikipedia</a> I found the formula
<code>$\arccos(x)={\frac {\pi }{2}}-\arctan \left({\frac {x}{\sqrt {1-x^{2}}}}\right)}$</code>, but that looks a bit complicated; and if it's not: Why didn't they add <code>acos</code> (arcus cosinus) using that definition?</p>
<p>Did I miss something obvious?</p>
