<p>How can I expand this to count all input boxes in a form that is <code>type="number"</code> but is currently disabled?</p>
<pre><code>let countIN = document.getElementsByTagName('input').length;
</code></pre>
<p>I can count all the input boxes (which included checkboxes) but I want to only count the specific disabled boxes only.</p>

<p>I am currently working on a huge csv file with pandas, and I need to find and print similarity between the selected row and every other row. For example if the string is "Card" and the second string is "Credit Card Debit Card" it should return 2 or if the first string is "Credit Card" and the second string is "Credit Card Debit Card" it should return 3 because 3 of the words match with the first string. I tried solving this using sets but because of sets being unique and not containing duplicates in the first example instead of 2 it returns 1. Because in a set "Credit Card Debit Card" is {"Credit", "Card", "Debit"}. Is there anyway that I can calculate this? The formula of similarity is ((numberOfSameWords)/whichStringisLonger)*100 as explained in this photo:</p>
<p><a href="https://i.stack.imgur.com/QHmJG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QHmJG.png" alt="" /></a></p>
<p>I tried so many things like Jaccard Similarity but they all work with sets and return wrong answers. Thanks for any help.
The code I tried running:</p>
<pre><code>def test(row1, row2):
return str(round(len(np.intersect1d(row1.split(), row2.split())) / max(len(row1.split()), len(row2.split()))*100, 2))
data = int(input("Which index should be tested:"))
for j in range(0,10):
print(test(dff['Product'].iloc[data], dff['Product'].iloc[j]))
</code></pre>
<p>and my dataframe currently looks like this:</p>
<p><a href="https://i.stack.imgur.com/l4vXs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l4vXs.png" alt="" /></a></p>
<p><code>print(df.sample(10).to_dict("list"))</code> returned me:</p>
<pre><code>{'Product': ['Bank account or service', 'Credit card', 'Credit reporting', 'Credit reporting credit repair services or other personal consumer reports', 'Credit reporting', 'Mortgage', 'Debt collection', 'Mortgage', 'Mortgage', 'Credit reporting'], 'Issue': ['Deposits and withdrawals', 'Billing disputes', 'Incorrect information on credit report', "Problem with a credit reporting company's investigation into an existing problem", 'Incorrect information on credit report', 'Applying for a mortgage or refinancing an existing mortgage', 'Disclosure verification of debt', 'Loan servicing payments escrow account', 'Loan servicing payments escrow account', 'Incorrect information on credit report'], 'Company': ['CITIBANK NA', 'FIRST NATIONAL BANK OF OMAHA', 'EQUIFAX INC', 'Experian Information Solutions Inc', 'Experian Information Solutions Inc', 'BANK OF AMERICA NATIONAL ASSOCIATION', 'AllianceOne Recievables Management', 'SELECT PORTFOLIO SERVICING INC', 'OCWEN LOAN SERVICING LLC', 'Experian Information Solutions Inc'], 'State': ['CA', 'WA', 'FL', 'UT', 'MI', 'CA', 'WA', 'IL', 'TX', 'CA'], 'ZIP_code': ['92606', '98272', '329XX', '84321', '486XX', '94537', '984XX', '60473', '76247', '91401'], 'Complaint_ID': [90452, 2334443, 1347696, 2914771, 1788024, 2871939, 1236424, 1619712, 2421373, 1803691]}

<p>I am new to AWS and trying to deploy a GraphQL API written in NodeJS as an AWS Lambda using Serverless. I have followed several tutorials that are close to what I am doing but cannot get the handler to work. The closest tutorial to what I am doing was using JavaScript, where I am using TypeScript. I followed closely but using TypeScript. I am getting errors that it cannot find the handler module (Error: Cannot find module 'lambda').</p>
<p>My handler file is named lambda.ts looks like this
`</p>
<pre><code>import {app} from './app';
import {serverless} from 'serverless-http';
export const handler = serverless(app);
</code></pre>
<p>`</p>
<p>My serverless.yml looks like this
`</p>
<pre><code>service: graphql-api
frameworkVersion: '3'
provider:
name: aws
runtime: nodejs12.x
region: us-east-1
functions:
serverlessApi:
handler: lambda.handler
</code></pre>
<p><code>app.ts</code></p>
<pre><code>import express from 'express';
import cors from 'cors';
import { graphqlHTTP } from 'express-graphql';
import { schema, resolvers } from './api-schema/';
import { loginMiddleware } from './login-middleware';
const app = express();
app.use(cors());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use(loginMiddleware);
app.use(
'/graphql',
graphqlHTTP({
schema: schema,
graphiql: true,
rootValue: resolvers,
})
);
export default app;
</code></pre>
<p>`
The lambda.js, app.ts, and serverless.yml files are all in the same root directory.</p>
<p>I have tried to convert the code to JavaScript and get errors that it cannot find the 'app' module. (Cannot find module './app')</p>
<p>lambda.js and looks like this
`</p>
<pre><code>const app = require('./app');
const serverless = require('serverless-http');
module.exports.handler = serverless(app);
</code></pre>
<p>`</p>
<p>I have also tried to export 'app' as default or named getting the same result. I am out of ideas. Any help is much appreciated.</p>

<p>I'm trying to come up with a function that gives me a "factorial" of a number but in a different way.
For example:</p>
<p><code>15! = 15*14/13+12-11*10/9... </code> and so on.</p>
<p>I tried doing this by first creating an array and, then, a loop to get to the result. But it doesn't work as expected. The result expected from the code below is 13.</p>
<pre><code>function createList(n) {
let input = n
let list = [input]
for(i = input-1; i >= 1; i--) {
list.push(i)
}
return list
}

<p>I want to build a self updating filter with checkboxes.</p>
<p>My Data:</p>
<pre class="lang-js prettyprint-override"><code>
const Shooting= [
{
name: "John & Johna ",
tag: ["wedding", "couple"],
img: [ src1 , src2, ...] //irrelevant
},
{
name: "Mario & Marie",
tag: ["couple", "NSFW"],
img: [ src1 , src2, ...] //irrelevant
},
];
export default Shooting;
</code></pre>
<p>how my output should look like that:</p>
<pre><code>Filter:
[]wedding
[]couple
[]NSFW
// [] are checkboxes, "couple" is a duplicate in the array
</code></pre>
<p>My code idea:</p>
<ol>
<li>Get all tags into a new array</li>
<li>Build function to remove duplicates from new array</li>
<li>list the filtered array with map-function -> Obj.map((tag))=>{...}</li>
</ol>
<p>My question:</p>
<p>How can I get all tags in a new list?</p>

<p>I have a tricky problem and I'm working on it for several hours but can't find a cause and solution of it. Hope someone help me.</p>
<p>I have to demonstrate function being called inside another function( pls see the comment in seminar.cpp)</p>
<p>Below are the files ( I have separated it into header and code files)</p>
<p><strong>main.cpp</strong></p>
<pre><code>#include <iostream>
#include <functional>
#include "seminar.h"
int main()
{
Tom::Car::Car car;
Nor::Driving drivingnow;
std::vector<uint8_t> X = car.road(drivingnow);
for(int i = 0 ; i < X.size() ; i++){
std::cout<<unsigned(X[i])<<" ";
}
return 0;
}
</code></pre>
<p><strong>seminar.h</strong></p>
<pre><code>#pragma once
#include "dist.h"
#include <vector>
#include <bits/stdc++.h>
namespace Tom
{
namespace Car
{
class Car
{
public:
std::vector<uint8_t> road(Nor::Driving &driving);
};
} // namespace Car
} // namespace Tom
</code></pre>
<p><strong>seminar.cpp</strong></p>
<pre><code>#include "seminar.h"
#include <algorithm>
#include <functional>
namespace Tom
{
namespace Car
{
std::vector<uint8_t> drive(Nor::Range &range)
{
std::vector<uint8_t> s;
s.push_back(range.z);
s.push_back(range.zz);
return s;
}
template <typename T, typename B, typename L>
std::vector<uint8_t> Content(T Sec, B Byte, L Func)
{
Nor::Range Rom;
std::vector<uint8_t> z = Func(Rom);
return z;
}
std::vector<uint8_t> Car::road(Nor::Driving &driving)
{
std::function<std::vector<uint8_t>(Nor::Range &)> Func = &drive;
return Content(driving, 1, Func); // passing drive function into content
}
} // namespace Car
} // namespace Tom
</code></pre>
<p><strong>dist.h</strong></p>
<pre><code>namespace Nor
{
class Driving{
public:
int x = 1;
};
class Range{
public:
int z = 50;
int zz = 100;
};
}
</code></pre>
<p>The above code and file structure works correctly and give me the correct expected output ie <code>50 100</code>
<strong>Live</strong> <a href="https://www.onlinegdb.com/elzbMBnYR#" rel="nofollow noreferrer">here</a></p>
<hr />
<p>Now I want to do more separation ie I want the implementation of <code>drive</code> function to move in another file ie in <code>type.cpp</code></p>
<p><strong>type.cpp</strong></p>
<pre><code>#include <algorithm>
#include "seminar.h"
#include <functional>
namespace Tom
{
namespace Car
{
std::vector<uint8_t> Car::drive(Nor::Range &range)
{
std::vector<uint8_t> s;
s.push_back(range.z);
return s;
}
} // namespace Car
} // namespace Tom
</code></pre>
<p><strong>seminar.h</strong></p>
<pre><code>#pragma once
#include "dist.h"
#include <vector>
#include <bits/stdc++.h>
namespace Tom
{
namespace Car
{
class Car
{
public:
std::vector<uint8_t> road(Nor::Driving &driving);
std::vector<uint8_t> drive(Nor::Range &range);
};
} // namespace Car
} // namespace Tom
</code></pre>
<p><strong>seminar.cpp</strong></p>
<pre><code>#include "seminar.h"
#include <algorithm>
#include <functional>
namespace Tom
{
namespace Car
{
template <typename T, typename B, typename L>
std::vector<uint8_t> Content(T Sec, B Byte, L Func)

Nor::Range Rom;
std::vector<uint8_t> z = Func(Rom);
return z;
}
std::vector<uint8_t> Car::road(Nor::Driving &driving)
{
std::function<std::vector<uint8_t>(Nor::Range &)> Func = &drive;
return Content(driving, 1, Func);
}
} // namespace Car
} // namespace Tom
</code></pre>

After doing this I am getting an below error:</p>

<p>Taking reference from <a href="https://stackoverflow.com/questions/7582546/using-generic-stdfunction-objects-with-member-functions-in-one-class">this</a> answer</p>

<hr />
<p>I don't know correctly what I am doing wrong in moving the implementation of <code>drive</code> function can someone please help with implementing the corrrect way.</p>
<p>Note:: I'm fine if the solution uses another way to pass the function ie by not using <code>std::function</code> . Thanks</p>

<p>I am new to selenium, and I get the following error: <code>element click intercepted: Element is not clickable at point (774, 8907)</code> whenever I run this code on the webpage that has the show more button. My goal is to get every element of the "table" on the webpage, but in order to do so I need to click "show more" button if it is present:</p>
<pre><code>driver = webdriver.Chrome(options=chrome_options)
driver.maximize_window()
for el in states_pages:
driver.get(el)
err = False
i = 0
while not err:
try:
more_button = driver.find_element(by=By.CLASS_NAME, value='tpl-showmore-content')
more_button.click()
except selexp.NoSuchElementException as e:
err = True
print(e)
except selexp.ElementClickInterceptedException as e:
err = True
print(e)
i+=1
</code></pre>
<p>I have tried using javascript executor, waiting until the button is clickable and crolling to the button by using actions, but this didn't work at all.</p>

<p>I just started learning express but already have a problem and I can't find any fixes. Somehow the req.body variable is undefined in the post. This is going to be a login system. (Sorry for my bad english)</p>
<p>I first tried to do it like here on github: <a href="https://github.com/WebDevSimplified/express-crash-course" rel="nofollow noreferrer">https://github.com/WebDevSimplified/express-crash-course</a> but i still had the "TypeError: Cannot read properties of undefined" error in my console. So I was looking for something else and found this: <a href="https://codeshack.io/basic-login-system-nodejs-express-mysql/" rel="nofollow noreferrer">https://codeshack.io/basic-login-system-nodejs-express-mysql/</a>
My code is based on the codeshack example but I'm still getting the error.</p>

<p>I am creating a simple blogging application and would like users to be able to like a post.</p>
<p>In terms of scalability I've decided it would be best to have likes as a separate table made up of pointers to both the user and post.</p>
<p>I have managed to enable the post request adding a like to the model however the <code>likes</code> field in the post model is not incrementing.</p>
<p>I've tried using a simple <code>likes += 1</code> technique in the serializer but that made no changes and have now used an <code>F</code> string but still no changes are being made. I am still fairly new to Django and suspect it may be because I'm trying to update a field on a different model within a <code>CreateAPIView</code> serializer but I'm not sure.</p>
<p>This is what I have so far</p>
<pre><code># views.py
class LikeView(generics.CreateAPIView):
permission_classes = [
permissions.IsAuthenticated,
]
queryset = Like.objects.all()
serializer_class = LikeSerializer
def like(self, request, format=None):
serializer = self.serializer_class(data=request.data)
if(serializer.is_valid()):
user_id = serializer.data.get('user_id')
post_id = serializer.data.get('post_id')
l = Like(user_id=user_id, post_id=post_id)
l.save()
# likes field not updating with this
post = Post.objects.get(id=post_id)
post.likes = F('likes') + 1
post.save()
return Response(LikeSerializer(l).data, status=status.HTTP_200_OK)
return Response(serializer.errors(), status=status.HTTP_400_BAD_REQUEST)
</code></pre>
<pre><code>#models.py
class Post(models.Model):
id = models.CharField(max_length=36, default=generate_unique_id, primary_key=True)
title = models.CharField(max_length=50)
content = models.TextField()
likes = models.IntegerField(default=0, blank=True)
pub_date = models.DateTimeField(default=timezone.now)
def __str__(self):
return self.title
class Like(models.Model):
user_id = models.ForeignKey(User, related_name='user_id', on_delete=models.CASCADE)
post_id = models.ForeignKey(Post, related_name='post_id', on_delete=models.CASCADE)
def __str__(self):
return "%s %s" % (self.user_id, self.post_id)
</code></pre>
<pre><code>#serializers.py
class LikeSerializer(serializers.ModelSerializer):
class Meta:
fields= (
'user_id',
'post_id'
)
model = Like
</code></pre>
<p>Thank you</p>

<p>So I am getting a list of strings from a server,</p>
<pre><code>let a="18647AF0D0,59,6]1864726D1,65,5]1864726A,85,5]1864726A,75,5]";
</code></pre>
<p>and with every set of data I am adding a close bracket, which means the set of data is now complete.</p>
<p>So The data look like this</p>
<pre><code>mac = "18647AF0D0";
TTL = "59"
TIME = "6"
</code></pre>
<p>And the server continues to send the data, which is added to the variable <code>a</code></p>
<p>Now This data I need to display on the web server on a HTML site, which has already been designed.</p>
<p>So The issue is here when the server sends sometime it sends a same mac value with a updated TTL and TIME</p>
<pre><code>1864726A,85,5]1864726A,75,5]
</code></pre>
<p>Here, if you see, I am getting the same mac value, so what I want to do is if the mac value already exists, then just update the TTL and TIME values on the same position; it should not be creating another entry.</p>
<p>So I was trying to store this value into an array using a split function, but it's getting too complicated, so I am stuck here.</p>
<p>Here is my html page :- <a href="https://codepen.io/kanxababu/pen/KKeZKQZ" rel="nofollow noreferrer">https://codepen.io/kanxababu/pen/KKeZKQZ</a></p>

<p>I have written some type conversion operators which only make sense in the context of a subset of types.</p>
<p>An example is below</p>
<pre><code>explicit virtual operator DataId<float>() const
{
static_assert(std::is_same_v<T, DataId<float>>, "std::is_same_v<T, DataId<float>>");
return data; // T data
}
</code></pre>
<p>This class contains an object of type <code>T=DataId<U></code>, where <code>U=float, int, double, std::string</code>.</p>
<p><code>static_assert</code> seems to demand that the argument passed to it to create the error message is a <code>const char*</code>.</p>
<p>Is there a way to print the type of <code>T</code> in the message?</p>
<p>I tried, but failed, with this attempt:</p>
<pre><code>constexpr auto message(
(std::string("std::is_same_v<T=") + typeid(T).name() + ", DataId<float>>").c_str()
);
static_assert<..., message>;
</code></pre>

<p>I have the following query:</p>
<pre><code>MATCH (n) WHERE n.uid IN $uids
WITH n as nodes, apoc.agg.minItems(n, n.level).items as highestNode
MATCH (nodes)-[:TRANSLATES_TO]-(a) where a.tree_id = apoc.agg.first(highestNode).tree_id
return nodes, a
</code></pre>
<p>I'm getting the error <code>Aggregations should not be used like this.</code> This is happening when introducing the <code>first</code> function on the third line of the query. <code>minItems</code> returns a map with the same key for each node so I need to get the first element of the map somehow. What <code>minItems</code> returns:</p>

<h1>Problem Statement</h1>
<p>I am trying to run a JavaScript code inside Python using <a href="https://github.com/cloudflare/stpyv8" rel="nofollow noreferrer">stpyv8</a>. However, I am getting the following error:</p>
<pre><code>Traceback (most recent call last):

<p>I have a <strong>button</strong> in my Flutter project that I want the <strong>phone number</strong> to appear when it's pressed by the user, and when the number appears, the user can <strong>copy the number</strong> and use it, or when pressing the button, it goes to a <strong>direct call process</strong> with the phone number</p>
<p>Is there a way or a widget by which I can achieve this?</p>

<p>My use case is to serve response of an HTTP request after receiving another request from separate server.</p>
<p><a href="https://i.stack.imgur.com/CHQX1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CHQX1.png" alt="enter image description here" /></a></p>
<ol>
<li>I want to do this best possible way keeping scaling in mind.</li>
<li>We are using Golang 1.19 with Gin Framework.</li>
<li>Server will have multiple pods thus channels will not work.</li>
<li>There will be timeouts for all request making initial request timed out after 60 seconds.</li>
</ol>
<p>My current solution is to use a shared cache where each pod will keep checking the cache. I believe, I can optimize this with channels where rather than checking in cache one by one, system periodically checks for any completed response.</p>
<p>I would also like to know how it could have been achieved in other programming languages.</p>
<p>PS: This is design based query, I have some reputation here to share bounty thus asking here. Please feel free to edit if question is not clear.</p>

<p>When I check my mssql server I see a new db created as per the name I gave in appsettinngs.json but only with 1 table - efmigrationhistory.</p>
<p>Why such? What mistake did I make? What needs to be done to get the migration going and create the full database with aspnet identity? Please suggest the correction;
Some help needed.</p>

<p>I try to create a relation between two tables in a Spring Boot Application.
I have the following Code:</p>
<pre><code> @Entity
@Table(name = "account")
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Account {
@Id
@Column(name="ID", nullable = false, updatable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE)
private Long id;
@Column(name="NAME", nullable = false)
private String name;
@Column(name="client_id", nullable = false)
private Long clientId;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "client_id", insertable=false, updatable=false)
private Client client;
}
@Entity
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Client {
@Id
@Column(name="client_id", nullable = false, updatable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE)
private Long id;
@Column(name="NAME", nullable = false, unique = true)
private String name;
@OneToMany(mappedBy = "client", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
private List<Account> accounts;
}
</code></pre>
<p>I always get the error relation "account" does not exist. What could be wrong?</p>
<pre><code> Caused by: org.postgresql.util.PSQLException: ERROR: relation "account" does not exist
</code></pre>

<p>I CANNOT USE ANY IMPORTED LIBRARY. I have this task where I have some directories containing some files; every file contains, besides some words, the name of the next file to be opened, in its first line. Once every word of every files contained in a directory is opened, they have to be treated in a way that should return a single string; such string contains in its first position, the most frequent first letter of every word seen before, in its second position the most frequent second letter, and so on. I have managed to do this with a directory containing 3 files, but it's not using any type of chain-like mechanism, rather a passing of local variables. Some of my college colleagues suggested I had to use slicing of lists, but I can't figure out how. I CANNOT USE ANY IMPORTED LIBRARY.
This is what I got:</p>
<pre><code>'''
The objective of the homework assignment is to design and implement a function
that reads some strings contained in a series of files and generates a new
string from all the strings read.
The strings to be read are contained in several files, linked together to
form a closed chain. The first string in each file is the name of another
file that belongs to the chain: starting from any file and following the
chain, you always return to the starting file.
Example: the first line of file "A.txt" is "B.txt," the first line of file
"B.txt" is "C.txt," and the first line of "C.txt" is "A.txt," forming the
chain "A.txt"-"B.txt"-"C.txt".
In addition to the string with the name of the next file, each file also
contains other strings separated by spaces, tabs, or carriage return
characters. The function must read all the strings in the files in the chain
and construct the string obtained by concatenating the characters with the
highest frequency in each position. That is, in the string to be constructed,
at position p, there will be the character with the highest frequency at
position p of each string read from the files. In the case where there are
multiple characters with the same frequency, consider the alphabetical order.
The generated string has a length equal to the maximum length of the strings
read from the files.
Therefore, you must write a function that takes as input a string "filename"
representing the name of a file and returns a string.
The function must construct the string according to the directions outlined
above and return the constructed string.
Example: if the contents of the three files A.txt, B.txt, and C.txt in the
directory test01 are as follows
test01/A.txt test01/B.txt test01/C.txt
-------------------------------------------------------------------------------
test01/B.txt test01/C.txt test01/A.txt
house home kite
garden park hello
kitchen affair portrait
balloon angel
surfing
the function most_frequent_chars ("test01/A.txt") will return "hareennt".
'''
def file_names_list(filename):
intermezzo = []
lista_file = []
a_file = open(filename)
lines = a_file.readlines()
for line in lines:
intermezzo.extend(line.split())
del intermezzo[1:]
lista_file.append(intermezzo[0])
intermezzo.pop(0)
return lista_file
def words_list(filename):
lista_file = []
a_file = open(filename)
lines = a_file.readlines()[1:]
for line in lines:
lista_file.extend(line.split())
return lista_file
def stuff_list(filename):
file_list = file_names_list(filename)
the_rest = words_list(filename)
second_file_name = file_names_list(file_list[0])
the_lists = words_list(file_list[0]) and
words_list(second_file_name[0])
the_rest += the_lists[0:]
return the_rest
def most_frequent_chars(filename):
huge_words_list = stuff_list(filename)
maxOccurs = ""
list_of_chars = []
for i in range(len(max(huge_words_list, key=len))):
for item in huge_words_list:
try:
list_of_chars.append(item[i])
except IndexError:
pass
maxOccurs += max(sorted(set(list_of_chars)), key = list_of_chars.count)

return maxOccurs

<p>A problem given by my lab professor, as the title reads:
<em>Find the largest combination given a list/array of integers.</em>
ie:</p>
<pre><code>input: {10, 68, 75, 7, 21, 12}
stdout: 77568211210
my output : 75768211210
</code></pre>
<p>The current code:</p>
<pre><code>import java.util.*;
import java.lang.*;
public class classwork6
{
static Scanner in = new Scanner(System.in);
static void sort(String[] arr)
{
for(int i=0;i<arr.length;i++)
{
for(int j=i+1;j<arr.length;j++)
{
if(arr[i].compareTo(arr[j])<0)
{
String temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
}
public static void main(String[] args)
{
int[] list = {10, 68, 75, 7, 21, 12};
String[] arr = new String[list.length];
for(int i=0;i<list.length;i++)
{
arr[i] = String.valueOf(list[i]);
}
sort(arr);
System.out.print(Arrays.toString(arr).replaceAll("[\\[\\], ]",""));
}
}
</code></pre>
<p>My first attempt was simply sorting the array, after which I quickly found out that 777568211210>75682112107</p>
<p>My latest attempt was to lexicographically compare the string values of the integers. Yet the output is still incorrect
777568211210>75768211210</p>

<p>i'm pretty new to html and css. Browsed through previously asked similar questions but non of the solutions seems to work for me. Basically I have this situation:</p>
<p><a href="https://i.stack.imgur.com/qyKKF.png" rel="nofollow noreferrer">Situation</a>.</p>
<p>The desired effect is the content to be visible through the semi-transparent header, but the header shouldn't overlap the scrollbar.</p>
<p>HTML is</p>
<pre><code><body>
<div class="flex">
<nav>
</nav>
<div class="container">
<header>
</header>
<div class="content">
some random text
</div>
</div>
</div>
<footer>
</footer>
</body>
</code></pre>
<p>CSS is</p>
<pre><code>*{
padding: 0;
margin: 0;
box-sizing: border-box;
}
.flex{
display: flex;
}
nav{
flex: 0 0 20rem;
background-color: black;
height: 90vh;
}
.container{
background-color: blue;
flex-grow: 1;
height: 90vh;
overflow-y: auto;
padding-top: 100px;
}
header{
height: 80px;
position: fixed;
top: 0;
left: 20rem;
right: 0;
z-index: 1;
background-color: rgba(0, 0, 0, 0.5);
}
.content{
height: 2000px;
color: white;
}
footer{
height: 10vh;
background-color: gray;
}
</code></pre>
<p>Only solution I've found is to put a value into header {right} equal to the width of the scrollbar, but that's of course not reliable for all browsers, so it's just a trick, not a real solution.</p>
<p>Tried using sticky but that way header doesn't overlap content as desired.</p>
<p>Tried to put header directly inside content but it doesn't work neither.</p>

<p>So I am trying to select all the rows that contains string equal to values from another table.</p>
<pre><code>SELECT q.QUERY, f.ANONID
FROM FACTS f
INNER JOIN QUERYDIM q
ON f.QUERYID = q.ID
WHERE q.QUERY IN (SELECT city FROM zipcodes);
</code></pre>
<p>q.QUERY is a string with different lengths
I want to select all the q.QUERY that contains value that is equal to any value in city</p>
<p>example</p>
<pre><code>one row:
q.QUERY = "this is a city called berlin"
</code></pre>
<p>another row:</p>
<pre><code>q.QUERY = "in cairo it is nice"
SELECT city FROM zipcodes = ("berlin","Birmingham","Huntsville",etc..)
</code></pre>
<p>so each q.QUERY loops through all the cities in the table every time</p>
<p>I am trying to find all the rows that has values of city</p>

<p>I have an array with values</p>
<pre><code>const range = [1,10,100,500,1000,2000,4000,8000]
let input = 1580
</code></pre>
<p>The expected output is 1000 because 1580 is between 1000 and 2000</p>
<p>But my code is giving wrong results and also giving incorrect for large values.</p>
<pre><code>for(i=0;i<range.length;i++)
{
if(input > range[i])
break;
}
console.log(range[i])
</code></pre>

<p>How to remove duplicate by ID. For each ID, the column Drug must have unique values. Any help is appreciated.</p>
<pre><code> dat <- read.table(text="Id Drug
A Meropenem
A Ampicillin

A Meropenem
A Ampicillin
A Augmentin

<p>I am writing shiny apps that take an object (a photograph or a matrix of numbers mostly) and making a set of plots to explore the object. I want to setup the shiny app as a function so I can call it from a command line and pass the object of interest directly to it. I would like to be able to return the name of the object in titles of the graphs and so forth. I can do this with substitute() outside of the shiny app, but when I put it in the shiny app it returns the name of object "inside the scope" of the shiny function, not the name of the objet that was passed to the shiny function.</p>
<p>Per suggestion, I used styler to improve the style of the code:</p>
<pre><code>
#this puts Children in the title of the graph which is what I want but I want a shiny app:
myPlot <- function(x) {
plot(1:10, main = substitute(x))
}
children <- "10"
myPlot(children)
#when I do it inside the shiny App
#this puts x in the title of the plot which is not what I want:
require(shiny)
app1 <- function(x) {
shinyApp(
ui = mainPanel(plotOutput("plot1")),
server = function(input, output) {
output$plot1 <- renderPlot(myPlot(x))
}
)
}
app1(children)
</code></pre>
<p>before the styler package:</p>
<pre><code>#this puts Children in the title of the graph which is what I want but I want a shiny app:
myPlot = function(x){
plot(1:10,main=substitute(x))
}
children = "10"
myPlot(children)
#when I do it inside the shiny App
#this puts x in the title of the plot which is not what I want:
app1 = function(x) {shinyApp(
ui = mainPanel(plotOutput("plot1")) ,
server = function(input,output){output$plot1 <- renderPlot( plot(1:10,main=substitute(x)) )}
)}
app1(children)
</code></pre>

<p>Hey this is my function</p>
<pre><code>function open() {
document.getElementById("main").style.marginLeft = "20%";
document.getElementById("mySidebar").style.width = "20%";
document.getElementById("mySidebar").style.display = "block";
document.getElementById("openNav").style.display = 'inline-block';
}
function close() {
document.getElementById("main").style.marginLeft = "0%";
document.getElementById("mySidebar").style.display = "none";
document.getElementById("openNav").style.display = "inline-block";
}
function Test() {
var item = document.getElementById("main").style.marginLeft ="";
if (item = "0%")
{
w3_open()
item = document.getElementById("main").style.marginLeft = "20%";
} else if (item = "20%")
{
w3_close()
}
</code></pre>
<p>}</p>
<p>First part works perfectly, but after second click none happens..</p>
<p>Idk whats wrong, can someone some suggestions?</p>
<p>///UPDATE</p>
<p>After clicking this:</p>
<pre><code><button id="openNav" class="w3-button w3-teal w3-xlarge" onclick="Test()">&#9776;</button>
</code></pre>
<p>I can open sidebar, but after clicking again i cannot close it. :/</p>

<p>I get two types of errors when I try to start or initiate the member function <code>temp_controll</code> from the subclass <code>Temperature_Controll</code>. The issue is that the while loops are started in a new thread.</p>
<p>I am having trouble passing the modbus client connection to the member function.</p>
<pre><code> AttributeError: 'ModbusTcpClient' object has no attribute 'modbus'
</code></pre>
<p>I don't understand the problem in its entirety, because I assumed I would inherit modbus.client from the main class?</p>
<p>The second problem was, when I comment out rp and want to access a member function from the main class "database_reading", I get the following error:</p>
<pre><code> AttributeError: 'str' object has no attribute 'database_reading'
</code></pre>
<p>How can I execute the subclass method via a second thread?</p>
<pre><code>class Echo(WebSocket):
def __init__(self, client, server, sock, address):
super().__init__(server, sock, address)
self.modbus = client
def database_reading(self)
do_something()
return data
class Temperature_Controll2(Echo):
def __init__(self, client):
super(Temperature_Controll, self).__init__(client)
self.modbus = client
def temp_controll(self, value):
#super().temp_controll(client)
while True:
print("temp_controll")
rp = self.modbus.read_coils(524, 0x1)
print(rp.bits[0])
self.database_reading()
def main():
logging.basicConfig()
with ModbusClient(host=HOST, port=PORT) as client:
client.connect()
time.sleep(0.01)
print("Websocket server on port %s" % PORTNUM)
server = SimpleWebSocketServer('', PORTNUM, partial(Echo, client))
control = Temperature_Controll2.temp_controll
t2 = threading.Thread(target=control, args=(client, 'get'))
t2.start()
try:
t1 = threading.Thread(target=server.serveforever())
t1.start()
finally:
server.close()
if __name__ == "__main__":
main()
</code></pre>
<p>This is a minimal example of my code, the thread t1 is executed without any problems. I have little experience with OOP programming, maybe someone here can help, thanks!</p>

<p>I tried checking all the nodes' children to see if those were leaves and then add them to their fathers but it seems I can't get the recursion done correctly</p>
<pre><code>t = { val: 1, sx: { val: 8, sx: { val: 7, sx: {}, dx: {} }, dx: { val:

<pre><code>struct User {
var name: String?
var drink: String?
}
let u1 = User(name: "Jack", drink: "Lemonade")
let u2 = User(name: "Jill", drink: "Iced Tea")
let list = [u1, u2]
var groupingDict = Dictionary(grouping: list, by: { $0.name })
print("groupingDict-original: ", groupingDict)
for (index, dict) in groupingDict.enumerated() {
if dict.key == "Jack" {
}
}
print("groupingDict-changed: ", groupingDict)

<p>My question is :
How do I find all the running processes that end with "sh".
I know that "ps aux" lists all the processes that are running and also "grep" prints a specific named process which is written inside " ".
I know I have to combine the command "ps aux" and also "grep" with a wildcard.</p>
<p>My solution is ps aux | grep "*sh" but it does not run properly.
How could it be solved?</p>

<p>I'm using a REST API from RapidApi, and I succeded in printing the whole response, but I need only some specific parameters. Like, to print only the Deprature and Arrival times. When using params:{} it doesn't help, because that prints every parameter with the specified argument. I need the inverse, to print a specific parameter with more arguments.</p>
<pre><code>import requests

headers = {

<p>I use a coroutine to add another coroutine to the event loop multiple times but partway through I cancel the first coroutine. I thought this would mean that any coroutines already added to the event loop would complete successfully and no more would be added, however I find that coroutines that have already been added to the event loop also seem to be cancelled.</p>
<p>I'm running this script in Spyder so I don't need to call run_until_complete, etc. because the event loop is already running in the background on my environment.</p>
<p>I'm sure I'm missing something and the code is behaving exactly as it should - but I can't figure out why. I would also like to know how I might allow cancellation of runTimes but still let slowPrinter complete.</p>
<p>Thank you!</p>
<p>Code below</p>
<pre><code>import asyncio
loop = asyncio.get_event_loop()
async def runTimes(async_func, times):
for i in range(0, times):
task = loop.create_task(async_func())
await task
async def slowPrinter():
await asyncio.sleep(2)
print("slowPrinter done")
async def doStuff():
for i in range(0, 10):
await(asyncio.sleep(1))
print("doStuff done")
async def doLater(delay_ms, method, *args, **kwargs):
try:
print("doLater " + str(delay_ms) + " " + str(method.__name__))
except AttributeError:
print("doLater " + str(delay_ms))
await asyncio.sleep(delay_ms/1000)
method(*args, **kwargs)
print("doLater complete")
task = loop.create_task(runTimes(slowPrinter, 3))
loop.create_task(doLater(3000, task.cancel))
loop.create_task(doStuff())
</code></pre>
<p>Output</p>
<pre><code>doLater 3000 cancel
slowPrinter done
doLater complete
doStuff done
</code></pre>
<p>Expected Output</p>
<pre><code>doLater 3000 cancel
slowPrinter done
doLater complete
**slowPrinter done**
doStuff done
</code></pre>
<p>Edit: Part of the reason I have built the code without using things like run_later is because I need to port the code to micropython later so I am sticking to functions I can use on micropython.</p>
<p>Edit2: Interestingly, task cancellation seems to propagate to tasks created from within the coroutine as well!</p>
<pre><code>async def runTimes(async_func, times):
for i in range(0, times):
task = loop.create_task(async_func())
try:
await task
except asyncio.CancelledError:
print("cancelled as well")
</code></pre>
<p>Output</p>
<pre><code>doLater 3000 cancel
slowPrinter done
doLater complete
cancelled as well
slowPrinter done
doStuff done
</code></pre>

<p>I am facing one problem when I want to filter an array inside an array by an array. Please see the example-</p>
<pre><code>const array1 = [
{
name: "this is name1",
products: [
{ id: "4" },
{ id: "2" },
]
},
{
name: "this is name2",
products: [
{ id: "2" },
{ id: "1" }
]
}
]
const array2 = [
{ id: "1", refund: true },
{ id: "2", refund: false },
{ id: "3", refund: true },
{ id: "4", refund: false}
]
</code></pre>
<p>Here I have to filter <code>array1</code> products field. Here in <code>array1</code> products filed an array with of id. I have to filter this products field by searching same object from array2 by id and then filter when refund is true.</p>
<p>From the example I need result by this-</p>
<pre><code>const array1 = [
{
name: "this is name2",
products: [
{ id: "1" }
]
}
]
</code></pre>
<p>Here in result we can see only one object in this array. Because from <code>array1</code>, in the object's product filed have two id <code>4</code> and <code>2</code>. From <code>array2</code> we can see refund <code>false</code> for both id <code>4</code> and <code>2</code>. That's why <code>array1</code> remove first object.</p>
<p>In the second object we can see products field contain two id <code>2</code> and <code>1</code>. From <code>array2</code> we can see refund is <code>false</code> for id <code>2</code> but refund is <code>true</code> for id <code>1</code>. Hence for id <code>1</code> refund is <code>true</code> that's why it stay in products array.</p>
<p>Please help me. I hope I can clear my questions.</p>

<p>I wrote simple server running script on node.js</p>
<pre><code>const http = require('http')
let requestsCount = 0
const server = http.createServer((request, response) => {
requestsCount++
response.write(`Leo Garsia ${requestsCount}`)
})
server.listen(3005, () => {
console.info('Server is Running on port 3005')
})
</code></pre>
<p>When in the browser I typed 'localhost:3005', it works a long time, before display first result. (about 10 minutes)
Why does it huppens?</p>
<p>And then when I refresh browser it requestsCount increments twice. And displays the result like 2,4,6, and so on.
Very interesting why?</p>

<p>When testing my react native app (with expo) through the expo go IOS app the icons are not vertically centered, however when testing on web they are vertically centered. I have tried giving each icon a parent div and centering it vertically, giving it a TabBarIconStyle of textAlignVertical: center, and textAlign: center, everything I can think of to vertically align these icons.</p>
<p>My Navigator:</p>
<pre class="lang-js prettyprint-override"><code><TabNav.Navigator screenOptions={TabNavOptions}>
<TabNav.Screen
name="Home"
component={HomeScreen}
options={{
tabBarIconStyle: { textAlignVertical: "center", textAlign: "center" },
tabBarIcon: ({ color, size }) => (
<View style={{}}>
<Ionicons name="home" color={color} size={size} style={{ textAlignVertical: "center" }} />
</View>
),
}}
/>
<TabNav.Screen name="Workouts" component={HomeScreen} options={{ tabBarIcon: ({ color, size }) => <Ionicons name="barbell" color={color} size={size} /> }} />
<TabNav.Screen name="Exercises" component={HomeScreen} options={{ tabBarIcon: ({ color, size }) => <Ionicons name="bicycle" color={color} size={size} /> }} />
</TabNav.Navigator>
</code></pre>
<p>My screen options for the Navigator:</p>
<pre class="lang-js prettyprint-override"><code>const TabNavOptions: BottomTabNavigationOptions = {
tabBarShowLabel: false,
tabBarActiveTintColor: "#4B7079",
tabBarInactiveTintColor: "#FFFFFF",
tabBarStyle: { width: "90%", height: 60, position: "absolute", left: "5%", bottom: 30, borderRadius: 100, borderTopWidth: 0, backgroundColor: "#75B1BC" },
};
</code></pre>
<p>This is what it looks like on web (and what it should look like)</p>
<p><a href="https://i.stack.imgur.com/UDFW4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UDFW4.png" alt="enter image description here" /></a></p>

<p>The definition of hasNext() is "Returns true if this scanner has another token in its input. This method may block while waiting for input to scan. The scanner does not advance past any input."</p>
<p>When I put <strong>standardInput.hasNext()</strong> in for-loop, the program runs toward infinity. But if i Put it in while-loop it does not run to infinity.
Where is the differenc between these two programs and why one of them work and another not?</p>
<p>for-loop:</p>
<pre><code>
import java.util.Scanner;
public class Vocabulary {
public static void main(String[] args) {
Scanner standardInput = new Scanner(System.in);
for(int i = 0; standardInput.hasNext(); i++){
System.out.print(i);
}
}
}
</code></pre>
<p>while-loop:</p>
<pre><code>
import java.util.Scanner;
public class Sum {
public static void main(String[] args) {
Scanner standardInput = new Scanner(System.in);
double sum = 0;
while(standardInput.hasNext()) {
double nextNumber = standardInput.nextDouble();
sum += nextNumber;
}
System.out.println("The Sum is " + sum + ".");
}
}
</code></pre>
<p>I read the definition, but still cannot understand why one program works but another not</p>

<p>I have a GlideImage that is inside a Box. Inside that Box, there is also a button with an icon. I want that, when I click on the button, the image is maximized and occupies the whole screen with a button in the lower right corner where it is possible to minimize it. I would also like to zoom in on it. Does anyone know how I can do this and if it's possible in the current state of Jetpack Compose?</p>
<p>I leave you the code I have to generate the Box, with the image and the icon.</p>
<p>Thanks in advance for any help.</p>
<pre><code>@ExperimentalGlideComposeApi
@Composable
fun BuildImage(imageUrl: String) {
Box(
modifier = Modifier
.padding(vertical = 25.dp, horizontal = 25.dp)
.background(
brush = Brush.linearGradient(
listOf(
Color.Gray,
Color.White
)
),
shape = RoundedCornerShape(14.dp)
)
.clip(RoundedCornerShape(14.dp))
) {
GlideImage(
model = imageUrl,
contentDescription = null,
contentScale = ContentScale.FillBounds
)
Box(modifier = Modifier.matchParentSize(), contentAlignment = Alignment.BottomEnd) {
IconButton(
onClick = { /* TO IMPLEMENT */ },
modifier = Modifier
.padding(11.dp)
.background(Color.Blue, RoundedCornerShape(3.dp))

<p>I want to know why am i getting an error when i delete temp in this function.</p>

<p>I tried commenting this delete out and it worked but its been leaking memory a simple solution i thought was to make a *temp in constructor then deleteing it in destruction assigning NULL in every function that needs it.</p>

<p>I am trying to apply the function on multiple data frames. I created a list for the data frames. If the ranking is less than 100, high performance column would be assigned values copied over from the ranking column and if the ranking is between 100 and 200, the average column would be assigned the values copied over from the ranking column. If the ranking is between 200 and 300, the lower performance column gets assigned values copied from the ranking column. I do not get any error messages when I run the script but the function does not get applied to the data frames. Any suggestions would be helpful.</p>
<pre><code>
for file in tests: #tests would be a list of data frame
def func (file):
if (file['ranking']) < 100:
(file['ranking']) == (file['High Performance'])
elif (file['ranking']) > 100 & (file['ranking'] < 200):
(file['ranking'])== (file['Average'])
elif (file ['ranking']) > 200& (file['ranking'] < 300):
(file['ranking']) == (file ['Low Performance'])
else:
return ''
file['High Performance'] = file.apply(func, axis=1)
file['Average'] = file.apply(func, axis=1)
file['Low Performance'] = file.apply(func, axis=1)

<p>I'm not asking for an answer to the question, but rather how I, on my own, could have gotten the answer.</p>
<h3><strong>Original Question:</strong></h3>
<p><strong>Does the following code cause Python to make a new list of size (len(nums) - 1) in memory that then gets iterated over?</strong></p>
<pre><code>for item in nums[1:]:
# do stuff with item
</code></pre>
<h3>Original Answer</h3>
<p>A similarish question is asked <a href="https://stackoverflow.com/questions/10079216/skip-first-entry-in-for-loop-in-python">here</a> and there is a subcomment by Srinivas Reddy Thatiparthy saying that a new sublist is created.
<strong>But, there is <em>no</em> detail given about how he arrived at this answer, which I think makes it very different from what I'm looking for.</strong></p>
<h3><strong>Question:</strong></h3>
<p><strong>How could I have figured out on my own what the answer to my question is?</strong></p>
<p><em>I've had similar questions before. For instance, I learned that if I do <code>my_function(nums[1:])</code>, I don't pass in a "slice" but rather a completely new, different sublist! I found this out by just testing whether the original list passed into <code>my_function</code> was modified post-function (it wasn't).</em>
<strong>But I don't see an immediate way to figure out if Python is making a new sublist for the <code>for</code> loop example.</strong> Please help me to know how to do this.</p>
<h4>side note</h4>
<p>By the way, this is the current solution I'm using from the original stackoverflow post solutions:</p>
<pre><code>for indx, item in enumerate(nums):
if indx == 0:
continue
# do stuff w items
</code></pre>

<p>I want to apply <code>gsub</code> on the following variables in my df:</p>
<pre><code>vars <- c("col1", "col2")
</code></pre>
<p>I want to use <code>gsub</code> to capitalize the first letter of every cell:</p>
<pre><code>df <- df %>%
as_tibble() %>%
mutate(across(vars), gsub, pattern = "^(\\w)(\\w+)", replacement = "\\U\\1\\L\\2", perl = TRUE)
</code></pre>
<p>But I'm getting the following error:</p>
<pre><code>Error in `mutate_cols()`:
! Problem with `mutate()` input `..2`.
ℹ `..2 = gsub`.
x `..2` must be a vector, not a function.
Run `rlang::last_error()` to see where the error occurred.

<p>Any guidance would be appreciated!</p>

<p>I have an edgelist in a pandas dataframe that looks like this:</p>
<pre><code> topic neighbor
0 K Kl
1 K Pr
2 Kl TS
3 Pr Kl
4 Pr Pr
</code></pre>
<p>When I turn this into a Graph (using networkx as nx) with <code>G = nx.from_pandas_edgelist(df)</code> it gives me KeyError: 'source'.</p>
<p>It works when I specify a source and target <code>G = nx.from_pandas_edgelist(df, "topic", "neighbor")</code> but this is an undirected Graph so I do not really want a source and target.</p>
<p>Is this the way it has to be done? Will specifying a source and target have implications for later calculations of degree_centrality?</p>

<p>normally we would use it like that:</p>
<pre><code>class TestClass
{
public $t;
public function set(\stdClass &$t)
{
$this->t = &$t;
}
}
$obj = new \stdClass();
$obj->fromOUTSIDE = 1;
$test = new TestClass();
$test->set($obj);
var_dump($test);
</code></pre>
<p><a href="https://onlinephp.io/c/cf4e3" rel="nofollow noreferrer">https://onlinephp.io/c/cf4e3</a></p>
<p>this results in the desired result:</p>
<pre><code>object(TestClass)#2 (1) {
["t"]=>
&object(stdClass)#1 (1) {
["fromOUTSIDE"]=>
int(1)
}
}
</code></pre>
<p>notice the & character, as its a reference. So far so good!</p>
<p>But what if the <code>__get</code> magic method creates this?</p>
<pre><code>class TestClass
{
public function __get(string $propertyName)
{
$xx = new \stdClass();
$xx->fromGET = 1;
$this->t = &$xx;
return $this->t;
}
}
$test = new TestClass();
$test->t;
var_dump($test);
</code></pre>
<p><a href="https://onlinephp.io/c/21f4f" rel="nofollow noreferrer">https://onlinephp.io/c/21f4f</a></p>
<p>the reference character disappeared!</p>
<pre><code>object(TestClass)#1 (1) {
["t"]=>
object(stdClass)#2 (1) {
["fromGET"]=>
int(1)
}
}
</code></pre>
<p>how to make it referenced? Even using the public function &__get form still no work!</p>
<p>EDIT:</p>
<p>So a basic code:</p>
<pre><code>class X
{
public \stdClass $t;
public function __construct(\stdClass &$t)
{
$this->t = &$t;
}
}
$t = new \stdClass();
$t->TTTT = 1;
$X = new X($t);
var_dump($t);echo "\r\n";
var_dump($X->t);echo "\r\n";
$t = new \stdClass();
$t->TTTT = 2;
var_dump($t);echo "\r\n";
var_dump($X->t);echo "\r\n";
</code></pre>
<p><a href="https://onlinephp.io/c/9cd7a" rel="nofollow noreferrer">https://onlinephp.io/c/9cd7a</a></p>
<p>see, it results #1, #1, #3, #1 because renewing the old object wont be affected the object inside the <code>X</code>.
If I do:</p>
<pre><code><?php
class X
{
public \stdClass $t;
public function __construct(\stdClass &$t)
{
$this->t = &$t;
}
}
$t = new \stdClass();
$t->TTTT = 1;
$X = new X($t);
var_dump($t);echo "\r\n";
var_dump($X->t);echo "\r\n";
$t = new \stdClass();
$t->TTTT = 2;
var_dump($t);echo "\r\n";
var_dump($X->t);echo "\r\n";
</code></pre>
<p><a href="https://onlinephp.io/c/8efd4" rel="nofollow noreferrer">https://onlinephp.io/c/8efd4</a></p>
<p>gives the desired result, #1, #1, #3, #3. But what if <code>$t</code> property doesn't exist? Maybe <code>__get</code> has to create it or obtain from an object-container. And this is where I can't solve it.</p>

<p>I have a bottom sheet dialog with 2 <code>nestedscrollview</code>, the outer one wrap the entire view, the inner one wrap a single <code>textview</code>, I have 2 problems:</p>
<p><em><strong>1.</strong></em>
the the inner one can scroll only down, as you can see in the gif:</p>
<p><a href="https://i.stack.imgur.com/KZCQ7.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KZCQ7.gif" alt="enter image description here" /></a></p>
<p>I need to make the inner <code>nestedscrollview</code> scrollable in both direction and the outer <code>nestedscrollview</code> scrollable when I drag outside the inner one, how can I do it?</p>
<p><em><strong>2.</strong></em>
I need to make the inner <code>nestedscrollview</code> to wrap text, tried with constraints but not working, wrap_content make the entire <code>textview</code> to be shown, making the <code>scrollview</code> a simple <code>textview</code>.</p>
<p>How can I do it?</p>
<p>This is my XML code:</p>
<pre><code><androidx.core.widget.NestedScrollView
android:id="@+id/outer_scrollview"
android:layout_width="match_parent"
android:layout_height="match_parent"

<p>I am struggling in writing a code that would produce a plot of any function with rectangle overlay of the area under the function for a specific interval. I see many examples of density functions with histograms but I want my rectangle to be bound by the function curve. We can take a function like x^2 as an example. Can someone help?
something like this:</p>

<p>I tried different codes but I am new to R.</p>

<p>I have below code :</p>
<pre><code>public async Task StartAsync(CancellationToken cancellationToken)
{
var cronExpressionVal = new Timer(async e => await GetCronExpression(cancellationToken), null, TimeSpan.Zero, new TimeSpan(0, 5, 0));
}
</code></pre>
<p>What I am trying to achieve is, <code>GetCronExpression</code> method should run at every 5 minutes.</p>
<p>But my problem is, when we first time run programme so it is coming in <code>StartAsync</code> method.</p>
<p>And it execute successfully.</p>
<p>Now it is not coming again in this method so my <code>GetCronExpression</code> method is not calling at every 5 minutes.</p>
<p>So my question is where should I put this <code>GetCronExpression</code> method call so it execute at every 5 minutes.</p>

<p>So I’m trying to create a buy and sell program and in there, I also coded the range where a random price out of a certain range will pop out. Now the problem is I can’t figure out a way on how to display a “not available today” on a 15% chance. so basically the price list will only show the price of the item OR a “not available today” note.</p>
<pre><code>this is how the code looks like now. i only inserted the price range and an srand function.
srand(time(NULL));
item1 = rand() % (1000 - 500 + 1) + 500;
item2 = rand() % (5000 - 1500 + 1) + 1500;
item3 = rand() % ( 8000 - 5000 + 1 ) + 5000;
printf("The Price of Item1 is %dG\n", item1);
printf("The Price of Item2 is %dG\n", item2);
printf("The Price of Item3 is %dG\n", item3);
</code></pre>

<p>Making a registration form for a website using Vue 3. I have a method, that gets values of password and password confirmation fields and compares it. If they're true - nothing happens, else - a red label appears and submit button gets disabled. I have implemented this in vue 3. but when passwords are equal, it dont works, but sometimes when they are not, it displays that they are.</p>
<pre><code><template>
<div>
<label for="password">Пароль</label>
<input type="text" v-model="password" name="password" id="password" placeholder="••••••••" required="">
</div>
<div>
<label for="confirm-password">Подтвердите Пароль</label>
<input @keydown="confirmPassword" type="confirm-password" v-model="confirm" name="confirm-password" id="confirm-password" placeholder="••••••••" required="">
<label for="confirm-password" v-if="invalidPasswords">Пароли не совпадают</label>
</div>
<button :disabled="submitDisabled" type="submit">Создать аккаунт</button>
</template>
<script>
export default {
name: "RegistrationView",
data () {
return {
...
password: '',
confirm: '',
invalidPasswords: false,
submitDisabled: false,
}
},
methods: {
confirmPassword() {

this.invalidPasswords = true
this.submitDisabled = true
} else {
this.invalidPasswords = false
this.submitDisabled = false
}
},

<p>I am trying to parse through a data structure and I have used a for loop initializing a variable i and using the range() function. I originally set my range to be the size of the records: 25,173 but then I kept receiving an</p>
<pre><code>---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
Cell In [63], line 41
37 input_list.append(HOME_AVG_PTS)
39 return input_list
---> 41 Data["AVG_PTS_HOME"]= extract_wl(AVG_PTS_HOME)
Cell In [63], line 28, in extract_wl(input_list)
26 if i==25172:
27 HOME_AVG_PTS[0]= HOME_AVG_PTS[0]/count
---> 28 elif int(Data(["TEAM_ID_AWAY"][i])) == const_home_team_id:
29 if type(PTS_AWAY[i]) is int:
30 count+= 1
IndexError: list index out of range
</code></pre>
<p>So I tried changing my for loop to be in the range of the function with the issue i.e.</p>
<pre><code>for i in range(len(Data["TEAM_ID_AWAY"])):
</code></pre>
<p>But I keep receiving the same error still</p>
<p>The Data variable holds the contents of a csv file which I have used the panda module to read and put into Data. You can assume all the column headers I have used are valid and furthermore that they all have range 25173.

HOME_AVG_PTS[0]= float(HOME_AVG_PTS[0]/count)
print(HOME_AVG_PTS)
input_list.append(HOME_AVG_PTS)
return input_list
Data["AVG_PTS_HOME"]= extract_wl(AVG_PTS_HOME)
</code></pre>
<p>Can anyone point out why I am having this error or help me resolve it? In the meantime I think I am going to just create a separate function which takes a list of all the AWAY_IDs and then parse through that instead.</p>

<p>I'm working on a canvas that allows dragging shapes like Figma. I want to draw a guideline (x, y) when shapes intersect each other, just like below.</p>
<p>I already handled when shapes are snapped, so we don't need to calculate when they snap each other, basically, we know when should draw the lines. Just couldn't figure out the calculation of lines. Also, we already know the rect values when the shapes are snapped.</p>
<p><strong>Edit:</strong></p>
<p>Here is the codepen link that you can play with it. You'll see the shapes are not always drawing correctly.</p>
<p><a href="https://codepen.io/lakers19/pen/ZEoPpKL" rel="nofollow noreferrer">https://codepen.io/lakers19/pen/ZEoPpKL</a></p>

"bottom": 325,
"top": 282,

"left": 938
}
}
</code></pre>
<p>According to these values, I want to apply styles something like this:</p>
<pre class="lang-js prettyprint-override"><code> guideLineX.style.left = `.. px`
guideLineX.style.top = `..px`
guideLineX.style.width = '1px'

<p>Reading a book about bash and it was introducing regular expressions(I'm pretty new to them) with an example:</p>
<pre><code>rename -n 's/(.*)(.*)/new$1$2/' *
'file1' would be renamed to 'newfile1'
'file2' would be renamed to 'newfile2'
'file3' would be renamed to 'newfile3'
</code></pre>
<p>There wasn't really a breakdown provided with this example, unfortunately. I kind of get what capture groups are and that .* is greedy and will match all characters but I'm uncertain as to why two capture groups are needed. Also, I get that $ represents the end of the line but am unsure of what $1$2 is actually doing here. Appreciate any insight provided.</p>
<p>Attempted to research capture groups and the $ for some similar examples with explanations but came up short.</p>

<p>I am currently struggling with moving data from a function calculation in R. I have 8 columns that have calculated a certain y value at the same point under different conditions (type), and my output looks like this:</p>
<pre><code>ydata <- output %>% select(x, type, y_a,y_b,y_c,y_d,y_e,y_f,y_g,y_h)
ydata
#> x type y_a y_b y_c ...
#> 1 1 1.3 <NA> <NA>
#> 2 1 2.7 <NA> <NA>
#> 3 1 4.4 <NA> <NA>
#> 1 2 <NA> 2.2 <NA>
#> 2 2 <NA> 3.3 <NA>
#> 3 2 <NA> 4.4 <NA>
#> 1 3 <NA> <NA> 3.3
#> 2 3 <NA> <NA> 7.6
#> 3 3 <NA> <NA> 11.3
...
</code></pre>
<p>However, my desired output would look like this, which I am unsure how to produce:</p>
<pre><code>#> x y_a y_b y_c ...
#> 1 1.3 2.2 3.3
#> 2 2.7 3.3 7.6
#> 3 4.4 4.4 11.3
...
</code></pre>
<p>I've tried using summarize() to group the variables together by x, but doing so would not shift the column's data in the desired way so that the <NA> values would not appear in the data frame.</p>

<p>I want to be able to access and modify attributes of HTML elements of a page in my server side code (I am using ASP.NET Core Razor Pages 6.0).</p>
<p>For example: a <code>.cshtml</code> file, I have a simple element like this:</p>
<pre><code><div class="mb-3 mt-3">
<label asp-for="User.firstname" class="form-label">First Name:</label>
<input asp-for="User.firstname" class="form-control" placeholder="First Name">
</div>
</code></pre>
<p>How do I access & change attributes of the above <code><input></code> element inside the <code>OnGet</code> or <code>OnPost</code> server-side methods?</p>
<p>I need to do so as I want to add a class to that <code><input></code> element, or make it read-only (depending on certain conditions in my server code).</p>
<p>In older versions of .NET, I believe this was possible by giving an HTML element an ID, and writing runat="server". Then, one could access the element in the code-behind via its ID and change its attributes. How is this done now in Razor Pages?
Should I not be able to do the same because of the asp-for tag helper which I used inn my code above? But how?</p>
<p>Thank you for your help!</p>

<p>I am trying to create a login functionality for my Reactjs Webiste using Nodejs express backend.</p>
<p>I want to set a JWT token when the user tries to log in and update that token in my mongoDB database and then verify the token on the frontend and save it to localStorage.</p>
<p>However, when the user tries to log in after registration, it returns back the result without the token, and thus not allowing the user to log in, unless he clicks the login button again, then my code would generate and update the user with the JWT token.</p>
<p>Why is this behavior happening? Why is the first response only returning the found user from the <code>findOne()</code> operation when i am resolving the result from the <code>findOneAndUpdate</code> operation?</p>
<p>Here is my code:</p>
<p>Auth Controller:</p>
<pre><code>login(params) {
params.email = params.email.toLowerCase();
return new Promise((resolve, reject) => {
db.collection("Users").findOne({ email: params.email }).then((response) => {
console.log(response)
if(response) {
bcrypt.compare(params.password, response.password, (err, success) => {
if(success) {
let token = jwt.sign({
name: response.name,
id: response._id
}, proccess.env.JWT_SECRET);
db.collection("Users").findOneAndUpdate({
email: params.email
}, {
$set: { token: token, lastLogin: new Date() },
}, function (e, s) {
if(e) {
console.log(e)
reject(e)
} else {
console.log("updated")
resolve(s)
}
})
} else {
reject({msg: 'Incorrect email or password.'})
}
})
} else {
reject({msg: 'cannot log in user'});
}
})
})
}
</code></pre>
<p>Auth Router:</p>
<pre><code>router.post('/login', (req, res) => {
let User = new models.User()
let processes = [];
processes.push(function (callback) {
User.login(req.body).then(function (response) {
callback(null, response);
}, function (error) {
console.log(error)
callback(error);
});
});
async.waterfall(processes, function (error, data) {
if (!error) {
return res.json({
statusCode: 200,
msg: 'User logged in successfully.',
result: data
});
} else {
return res.json({
statusCode: 401,
msg: 'Cannot login user.',
error: error
});
}
});
})
</code></pre>
<p>React Login.js:</p>
<pre><code>const login = () => {
axios.post('/login', data).then(async (response) => {
console.log(response)
if(response && response.data.result.value.token ) {
localStorage.setItem("authUser", JSON.stringify(response.data.result.value.token))
history.push("/")
console.log(response.data.result)
} else {
console.log("ERROR")
}
})
}
</code></pre>

<p>The context here is that I'm comparing the values of two columns—the key and the date. If the criterion is met, we will now create a new column with the flag = Y else ""</p>
<p>Condition: if key are matching and date in df1 > date in df2 then "Y" else ""</p>
<p>We will therefore iterate through all of the rows in df1 and see if the key matches in df2, at which point we will check dateF and date for that row to see if it is greater, and if it is, we will save "Y" in a new column flag.</p>
<p>Update 1:
There can be multiple rows in df1 with same key and different dates</p>
<p>Df1:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Key</th>
<th>Date</th>
<th>Another</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>2022-03-04</td>
<td>Apple</td>
<td></td>
</tr>
<tr>
<td>321</td>
<td>2022-05-01</td>
<td>Red</td>
<td></td>
</tr>
<tr>
<td>234</td>
<td>2022-07-08</td>
<td>Green</td>
<td></td>
</tr>
</tbody>
</table>
</div>
<p>Df2:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Key</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>2022-03-01</td>
</tr>
<tr>
<td>321</td>
<td>2022-05-01</td>
</tr>
<tr>
<td>234</td>
<td>2022-07-01</td>
</tr>
</tbody>
</table>
</div>
<p>Expected O/P:
Explanation: as we can see first row and 3rd row key are matching and the DateF in df1 > Date in df2 so Y</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Key</th>
<th>Date</th>
<th>Another</th>
<th>Flag</th>
</tr>
</thead>
<tbody>
<tr>
<td>123</td>
<td>2022-03-04</td>
<td>Apple</td>
<td>Y</td>
</tr>
<tr>
<td>321</td>
<td>2022-05-01</td>
<td>Red</td>
<td></td>
</tr>
<tr>
<td>234</td>
<td>2022-07-08</td>
<td>Green</td>
<td>Y</td>
</tr>
</tbody>
</table>
</div>
<p>Code to create all dfs:</p>
<pre><code>import pandas as pd
data = [[123, pd.to_datetime('2022-03-04 '),'Apple'],
[321, pd.to_datetime('2022-05-01 '),'Red'],
[234, pd.to_datetime('2022-07-08 '),'Green']]
df1 = pd.DataFrame(data, columns=['Key', 'DateF', 'Another'])
#df2
data1 = [[123, pd.to_datetime('2022-03-01 ')],
[321, pd.to_datetime('2022-05-01 ')],
[234, pd.to_datetime('2022-07-01 ')]]
df2 = pd.DataFrame(data1, columns=['Key', 'Date'])
</code></pre>
<p>Have tried this but i think i am going wrong.</p>
<pre><code>for i in df1.Key.unique():
df1.loc[(df1[i] == df2[i]) & (r['DateF'] > df2['Date]), "Flag"] = "Y"
</code></pre>
<p>Thank You!</p>

<p>I'm solving some exercises from a book and now I'm having some difficulties:
In this exercise I shall implement Card as an instance of the class Ord.
But I don't know how exactly I could implement it, so I would appreciate any help.</p>
<p>My code so far looks like this:</p>
<pre><code>data Suit = Diamond | Club | Spade | Heart
data Rank = Seven | Eight | Nine | Ten | Jack | Queen | King | Ace
data Card = Card Suit Rank
instance Ord Card where
....
</code></pre>
<p>Now I don't know how exactly to implement this and I would very much like to understand it.
Thanks in advance for the explanations.</p>

<p>I have a web story that has cencored word in it with asterix</p>
<p>right now i'm doing it with a simple and dumb str.replace</p>
<p>but as you can imagine this is a pain and I need to search in the text to find all instance of the censoring</p>
<p>here is bastard instance that are capitalized, plurial and with asterix in different places</p>
<pre><code>toReplace = toReplace.replace("b*stard", "bastard")
toReplace = toReplace.replace("b*stards", "bastards")
toReplace = toReplace.replace("B*stard", "Bastard")
toReplace = toReplace.replace("B*stards", "Bastards")
toReplace = toReplace.replace("b*st*rd", "bastard")
toReplace = toReplace.replace("b*st*rds", "bastards")
toReplace = toReplace.replace("B*st*rd", "Bastard")
toReplace = toReplace.replace("B*st*rds", "Bastards")
</code></pre>
<p>is there a way to compare all word with "*" (or any other replacement character) to an already compiled dict and replace them with the uncensored version of the word ?
maybe regex but I don't think so</p>

<p>I have this code here which supposedly builds a list from a document in firebase, which ultimately fails as it always goes to <code>return loading</code>. From what I know, it has something to do with it being a future and I think I am accessing it wrongly. I have tried getting the output as Text and it works, but as a a listview, it does not.</p>
<p>I also tried making a function with async on it but the app still outputs loading. Any help would be appreciated.</p>
<pre><code>Widget showFriend() {
CollectionReference users = FirebaseFirestore.instance.collection('todos');
return FutureBuilder<DocumentSnapshot>(
future: users.doc(documentId).get(),
builder:
(BuildContext context, AsyncSnapshot<DocumentSnapshot> snapshot) {
if (snapshot.hasError) {
return Text("Something went wrong");
}
if (snapshot.hasData && !snapshot.data!.exists) {
return Text("Document does not exist");
}
if (snapshot.connectionState == ConnectionState.done) {
Map<String, dynamic> data =
snapshot.data!.data() as Map<String, dynamic>;
List<dynamic> fren = [];
void waitList() async {
List<dynamic> temp;
temp = await (data['friends']);
fren = temp;
}
waitList();
fren = List.from(data['friends']);
print(fren);
if (fren.length > 0) {
ListView.builder(
itemCount: fren.length,
itemBuilder: (context, index) {
return ListTile(title: Text('${fren[index]}'));
});
}
}
return Text("loading");
});
}

<p>I am trying to run a Gstreamer plugin written to run <a href="https://github.com/voidmainvoid95/gst-nvmaxine" rel="nofollow noreferrer">NVIDIA Maxine filters</a> through the pipeline.</p>
<p>I keep getting <code>no element "nvmaxinevideofx"</code>, and I'm wondering if there is anything fundamentally wrong with my approach or if I'm just making a mistake somewhere.</p>
<p>I am super new to Gstreamer and any help would be much appreciated.</p>
<p>I am running on Ubuntu 20.04 through WSL.</p>
<p>I managed to build the plugin files successfully, but no matter how I add the plugin path to the build directory containing the <code>.so</code> files, it's not getting picked up by either <code>gst-launch</code> or <code>gst-inspect</code>.</p>
<p>I tried both adding to the <code>GST_PLUGIN_PATH</code> variable and as an argument to <code>gst-launch</code> with <code>--gst-plugin-path</code>.</p>
<p>I have also managed to get Maxine installed at <code>/usr/local/VideoFX</code>.</p>
<p>I have also managed to build the <code>gst-template</code> plugin from the official tutorials and run it successfully with:</p>
<pre><code>gst-launch-1.0 -v -m --gst-plugin-path=/mnt/d/projects/stream/gst-template/build/gst-plugin/ fakesrc ! my_filter ! fakesink silent=TRUE
</code></pre>
<p>But when I try to run the same thing with the appropriate parameters for this plugin it returns <code>no element "nvmaxinevideofx"</code>:</p>
<pre><code>gst-launch-1.0 -v -m --gst-plugin-path=/mnt/d/projects/stream/gst-nvmaxine/build/ fakesrc ! nvmaxinevideofx ! fakesink silent=TRUE
</code></pre>

<p>I would like to draw a line graph with multiple X-axis values, something like a dodged bar graph, but with a line graph.
The graph should look something like this:
<a href="https://i.stack.imgur.com/KJFpy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KJFpy.png" alt="Graph Image" /></a></p>
<p>My attempt until now is this:</p>
<pre><code>
df %>%
pivot_longer(ACI:SB) %>%
mutate(across(where(is.character), as.factor)) %>%
ggplot(aes(x = R, y = value, group=name)) +
geom_line()+
facet_wrap(~A, nrow=1, strip.position="bottom")
</code></pre>
<p>This code is currently outputting this:
<a href="https://i.stack.imgur.com/fTJMN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fTJMN.png" alt="Wrong Output" /></a></p>
<p>I'd greatly appreciate any help, thanks</p>

<p>I have a long string stored in a variable in Rust. I often remove some characters from its front with a <code>drain</code> method and use the value returned from it:</p>
<pre class="lang-rust prettyprint-override"><code>my_str.drain(0..i).collect::<String>();
</code></pre>
<p>The problem is, that draining from this string is done <em>really often</em> in the program and it's slowing it down a lot (it takes ~99.6% of runtime). This is a very expensive operation, since every time, the entire string has to be moved left in the memory.</p>
<p>I do not drain from the end of the string at all (which should be much faster), just from the front.</p>
<p>How can I make this more efficient? Is there some alternative to <code>String</code>, that uses a different memory layout, which would be better for this use case?</p>

<p>I want to limit number of rows in tableView say I want to show only 2 rows initially and if user clicks "See All" button then display all the rows. The data (array) for tableView is coming from CoreData. I have entered (saved) all the data in another ViewController, and fetching data on some another ViewController. There might be a case where data may be nil. Currently, I'm displaying all the rows just like --> return array.count, but I have no idea how to achieve my condition ?</p>

<p>I wrote an extension function to get an element of an JSON object by its name:</p>
<pre class="lang-kotlin prettyprint-override"><code>fun JSONObject.obj (name: String): JSONObject? =
try { this.getJSONObject(name) }
catch (e: JSONException) { null }
</code></pre>
<p>Now I want to extend this for nested JSON objects. I wrote the following:</p>
<pre class="lang-kotlin prettyprint-override"><code>tailrec fun JSONObject.obj (first: String, vararg rest: String): JSONObject? =
if (rest.size == 0)
obj(first)
else
obj(first)?.obj(rest[0], *rest.drop(1).toTypedArray())
</code></pre>
<p>But this looks quite inefficient to me.</p>
<p>What is the best way to slice a <code>vararg</code> argument?</p>

<p>hope you are doing fine
i came across to a problem of data array manipulation at starting there was not much manipulation required as work progressed now more data manipulation is required and i am running short on this(as a fresher early days of my career
problem explanation - as data i am receiving an array of object and each object contains another array of information (key-value pair) and that array also contains another array of information(key value pair ) and requirement is to i have to loop main data object-item with respect to length of deep nested array and display them on front except this i have done the most part.
i am attaching a sample code of my problem below i am requesting you guys to provide solution for this issue</p>
<p>`</p>
<pre><code>import React, { useState } from "react";
const data = [
{
id: 1,
name: "Something Goes here",
address: "Earth",
arr1: [
{
newId: 1,
title: "Title 1",
midName: "Nothing",
arr2: [
{
subId: 1,
goes: "Hello",
ollo: "Not what you think",
},
{
subId: 2,
goes: "Hello 2",
ollo: "Not what you",
},
],
},
],
},
{
id: 2,
name: "Something Goes",
address: "Mars",
arr1: [
{
newId: 3,
title: "Title sddsdsad",
midName: "Nothing",
arr2: [
{
subId: 2,
goes: "Hello adasdasdasd",
ollo: "Not what you think asdasdasdawd",
},
{
subId: 2,
goes: "Hello 2",
ollo: "Not what you asdasasd",
},
],
},
],
},
];
const App = () => {
const [dummy, setDummy] = useState([]);
let dummyArr = [],
tempObj,
temp;
const tempFunc = () => {
for (let i = 0; i < data.length; i++) {
for (let j = 0; j < data[i].arr1; j++) {
for (let k = 0; k < data[i].arr1[j].arr2; k++) {
temp = data[i].arr1[j].arr2[k];
delete data[i].arr1[j].arr2[k];
tempObj = { ...temp ,...data[i], };
dummyArr.push(tempObj);
tempObj = {};
console("tempObj -->", tempObj);
}
}
}
};
console.log("dummyArr", dummyArr);
return (
<React.Fragment>
<button>Hello oooo</button>
</React.Fragment>
);
};
export default App;
</code></pre>
<p>expected result is to have both arrays pushed into main itemObject
`</p>
<pre><code>const sampleArray = [
{
id: 2,
name: "Something Goes",
address: "Mars",
newId: 3,
title: "Title sddsdsad",
midName: "Nothing",
subId: 2,
goes: "Hello adasdasdasd",
ollo: "Not what you think asdasdasdawd",
},
];

<p>I am creating an <code>AuthGuard</code> for my app..now when i try to load the component without getting <strong>logged in</strong> it should redirect me to the login page..But i am getting an error like following
<a href="https://i.stack.imgur.com/dQvUy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dQvUy.png" alt="image error" /></a></p>
<p>and nothing happens.</p>
<p>I am throwing this error from my backend <code>{"status":401,"message":"Auth Token Not found!"}}</code>
as there is no auth token</p>
<p>The following is the code of my <code>AuthGuard</code></p>
<pre><code>export class AuthGuardService implements CanActivate {
constructor(private authService: AuthService, private router: Router) { }
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean | Observable<boolean> {
return this.authService.checkLogin().pipe(
map((data: HttpResponse) => {
if (data.status == 200) {
console.log("OUTPUT:", data)
return true
}
else return false
}),
)
}
}
</code></pre>
<p>The following is my function in <code>AuthService</code>:</p>
<pre><code> public checkLogin():Observable<HttpResponse> {
return this.http.get<HttpResponse>('http://localhost:5000/auth/check-login', { withCredentials: true })
}
</code></pre>
<p>Now how can i handle the errors like these and set a fallback value to <code>false</code> so if any error occurs then that route could not be accessed</p>

<p>I have written the following code to read a csv file into a multidimensional list which is working fine. The problem arise when I created a function to calculate the total of 2D list. This is happening because the numbers are in string inside the 2D list i.e.</p>
<p>[['0', '0', '30', '2', '21', '13', '23'], .....,['8', '25', '1', '6', '21', '23', '0']].</p>
<p>What would be the simplest way to convert the string elements into integers in a 2D list such as</p>
<p>[[0, 0, 30, 2, 21, 13, 23],.....,[8, 25, 1, 6, 21, 23, 0]]</p>
<p><strong>My code so far</strong></p>
<pre><code>rows = 52
cols = 7
def populate2D():
with open("rainfall.csv","r") as file:
lineArray = file.read().splitlines()
matrix = []
for line in lineArray:
matrix.append(line.split(","))
return matrix
def display(matrix):
print(matrix)
def yearly(matrix):
total = 0
for row in matrix:
for value in row:
total += value
return total
matrix = populate2D()
display(matrix)
total = yearly(matrix)
print()
print("Total rainfall for the year is " + str(total))

<p>Why is R complaining about an error when my function already handles errors?</p>
<p>I've created a function to grab the parent element of an href attribute which invariably is "<a>". The function has some error handling to return NA if it can't find the href attribute.</p>
<p>The function works just fine in isolation, but not in combination with dplyr::mutate. I can't figure out why that is.</p>
<p>Minimal reproducible example:</p>
<pre><code># Create html doc
html.test <- "<a href=\"hello\"</a><a id=\"ctl00_ctl00_btnSearch\" data-action=\"search\" class=\"go\" href=\"javascript:__doPostBack('ctl00%24ctl00%24btnSearch','')\"><span>GO</span><i class=\"fal fa-search\"></i></a>" %>%
minimal_html()
# Create function
fun.get.node.name <- function(href.target){
# treat warnings as errors
options(warn=2)
xpath <- paste0("//a/@href[.= \'", href.target, "\']/..")
res <- try({
node_name <- html_nodes(x = html.test, xpath = xpath) %>% html_name()
}, silent = TRUE)
if (inherits(res, "try-error")) {
# print warnings as they occur
options(warn=1)
return(NA)
} else {
# print warnings as they occur
options(warn=1)
return(node_name)
}
}
</code></pre>
<p>Now, if I apply the function to the attribute href = "hello", it works fine both in isolation and when applied within dplyr::mutate:</p>
<pre><code>href.target <- "hello"
fun.get.node.name(href.target)
[1] "a"
data.frame(href = href.target) %>% mutate(node_name = fun.get.node.name(href.target = href))
href node_name
1 hello a
</code></pre>
<p>But, if I apply the same function to the attribute href = "javascript:__doPostBack('ctl00%24ctl00%24btnSearch','')" (which for some reason can't be found) then the function works only in isolation and NOT when applied within dplyr::mutate:</p>
<pre><code>href.target <- "javascript:__doPostBack('ctl00%24ctl00%24btnSearch','')"

<p>Recently I started to learn Cassandra. I needed to design the database for my web application. So, I prepared conceptual data model as well as application workflow, and currently I’m stuck on something…</p>
<p>Let me provide you with some details of the issue. Well, I want to show all friends of currently logged-in user WITH PROFILE PICTURES AND THEIR FULL NAME.</p>
<p>So I probably need two tables:</p>
<p><a href="https://i.stack.imgur.com/sjtXo.jpg" rel="nofollow noreferrer">Fragment of Application Workflow</a></p>
<pre><code>**users_by_id**
- user_id PARTITION KEY
- email
- password
- profile_image
- full_name
</code></pre>
<pre><code>**friends_by_user_id**
- user_id PARTITION KEY (whose friend is it)
- friend_id (user id of the friend)
etc.
</code></pre>
<p>And now let’s say I want to display all friends in a list, but the problem is the user expects the app to show <strong>their profile pictures and their full name (not just the friend‘s user id), so the user can recognize who is who</strong> (pretty logical, right?).
So, how do I do that? I mean I could get the users id and then query the users table to finally get the full name and profile picture individually. Although, I don’t think it would be very efficient (because what if the user have hundreds of friends?!).</p>
<p>What is the right way to solve this problem? Thanks in advance!</p>

<p>i have an interface(IDomainService) and a (lot) like it in my app which i mark more interfaces with it(IProductionLineTitleDuplicationChecker ) like what u will see in the rest:</p>
<pre><code>public interface IDomainService
{
}
</code></pre>
<pre><code>public interface IProductionLineTitleDuplicationChecker : IDomainService
{
///
}
</code></pre>
<p>and the implementation like this:</p>
<pre><code>public class ProductionLineTitleDuplicationChecker : IProductionLineTitleDuplicationChecker
{
private readonly IProductionLineRepository _productionLineRepository;
public ProductionLineTitleDuplicationChecker(IProductionLineRepository productionLineRepository)
{
_productionLineRepository = productionLineRepository;
}
public bool IsDuplicated(string productionLineTitle)
{
///
}
}
</code></pre>
<p>right now im using the <strong>built-in DI-container</strong> to <strong>resolve and register</strong> the services but i want to change it and use <strong>scrutor</strong> instead</p>
<p>how can i resolve and register my <strong>Services</strong> using <strong>scrutor</strong>?</p>

<p>I always get the output <code>None</code> instead of <code>False</code></p>
<p>My code:</p>
<pre><code>def bi_search(elements: list, x) -> bool:
i = len(elements)/2-1
i = int(i)
print(i)
if i == 0:
return False
elif x == elements[i]:
return True
elif x < elements[i]:
e = elements[0:i + 1]
bi_search(e, x)
elif x > elements[i]:
e = elements[i+1:len(elements)]
bi_search(e, x)
</code></pre>
<p>commands:</p>
<pre><code>my_list = [1, 2, 5, 7, 8, 10, 20, 30, 41, 100]
print(bi_search(my_list, 21))
</code></pre>
<p>Output:</p>
<pre><code>4
1
0
None
</code></pre>
<p>I don't get it, it even says that is i = 0 right before the statement, so why do I not get False as a result?</p>

<p>I have a little doubt. How can I make the marker parameter change to marker1, marker2, marker3 depending on how many elements are in the map?</p>
<p>i have this but i want that for each element of the map there is a +1 for each marker</p>
<pre><code> {teams.map((team) =>
<pointer
marker={marker1}
</code></pre>
<p>for example, that the first element of the .map has the parameter {marker1}, the second {marker2}, the third {marker3} and so on</p>

<p>I developed a Rest API with some logs (requests, responses, more info and errors)</p>
<p>I saw that if there are simultaneous requests, logs mix and you cant follow the execution in logs because you dont know which request was used for that log line.</p>
<p>Is there any execution id that can be added at the beginning of every log line so I can follow the execution of that request?.</p>
<p>I'm using Log4j</p>

<p>I am a newbie with this. I have created a database of hundreds of proverbs and their MEANING, as well as Headwords and their definitions (MEANS).</p>
<p>I would like to generate a graph of a random Proverb, but with the related words and definitions.</p>
<p>My current cypher query that does return some interesting data looks as so:</p>
<pre><code>MATCH p=()-[:MEANS]-(a:Headword)-[:USED_IN]-(d:Proverb)-[:MEANING]-()
RETURN p, rand() as r
ORDER BY r
LIMIT 1
</code></pre>
<p>I am getting a random Proverb, but the USED_IN and MEANS relations are also limited to 1.<br />
I am wanting to produce something like below where there is a single Proverb and its MEANING (Orange), but there are relations to the words USED_IN (yellow), and the defintions (MEANS) of those words. How can I attain that?</p>
<p>Just an FYI for the image below I bumped up the LIMIT in the cypher query to 3. But this may also produce 3 Proverbs etc.</p>

<p>Imagine a parent class which has a mangled attribute, and a child class:</p>
<pre class="lang-py prettyprint-override"><code>class Foo:
def __init__(self):
self.__is_init = False
async def init(self):
# Some custom logic here, not important
self.__is_init = True
class Bar(Foo):
...
# Create class instance.
bar = Bar()
# How access `__is_init` of the parent class from the child instance?
</code></pre>
<p>How can I get a <code>__is_init</code> value from a parent (<code>Foo</code>) class?</p>
<hr />
<p>Obviously, I can <code>bar._Foo__is_init</code> in this example, but the problem is that class name is dynamic and I need a general purpose solution that will work with any passed class name.</p>

<p>I was able to shuffle through my deck of cards (array of objects), but now I'm trying to pull out/remove the first 25 cards(objects) and place them into their own stored array. However, my code is returning undefined when I try to reference the new deck cards var player1Deck = shuffledCards.splice(25); is returning as not a function. Is there anyway to remove the first 25 cards/object from this new shuffled array that I created?</p>

<p>My aim is to create my own analogue of <code>std::basic_string</code> but with some additional conditions. I want my <code>AnyString<CharType, Traits></code> to be convertible from <code>std::basic_string<CharType, AnyOtherTraits, AnyAlloc></code> but I want to disable this constructor for some CharType such that <code>basic_string<CharType></code> does not exist (compile).</p>
<p>I tried to do something like that:</p>
<pre><code> template<typename OtherTraits, typename Alloc, typename =
std::enable_if_t<!std::is_array_v<char_type> &&
std::is_trivial_v<char_type> &&
std::is_standard_layout_v<char_type>>>
AnyString(const std::basic_string<char_type, OtherTraits, Alloc>&);
</code></pre>
<p>And I have <code>ColouredChar</code>, which does not meet the conditions listed inside <code>enable_if_t</code>.</p>
<p>Now, when I'm trying to call the disabled constructor :</p>
<pre><code>std::basic_string<ColouredChar> de("string"_purple);
ColouredString d(de);
</code></pre>
<p>I do not only get the compile errors from <code>basic_string</code> but also very strange one, telling me that completely different PRIVATE constructor constructor cannot convert its parameter from <code>basic_string</code>.</p>
<p>Is there any way to make these compile errors more readable? Or at least explain whether there's anything here to worry about.</p>
