74,402,780 | <h1>Context:</h1>
<p>I'm currently coding a bot on Discord. The bot has a server class within it (with none of the fancy websockets and http requests) and a client class that serves as a bridge between the user and the server. The instance of the client class manages sending log messages to its corresponding user, updating its GUI (which is just an embed and a bunch of buttons attached to it which), and calling methods on the server class.</p>
<p>Currently I'm stuck on log messages. The current system is that a GUI message that contains the controls would always be the most recently sent message.</p>
<p>If another user were to join a room on the server class, this would cause the GUI message to not be updated anymore. Additionally, a log message would be sent to the user, which would cause the GUI message to not be the most recently sent message. Both problems are solved by the bot deleting the old GUI message and sending the updated one after that.</p>
<p>However, concurrent room joins may occur, so there's a chance the bot would interleave the "delete message" and "send message" parts of updating the GUI message like this:</p>
<pre class="lang-py prettyprint-override"><code>delete_message()
delete_message() # !!!
send_message()
send_message()
</code></pre>
<p>The second <code>delete_message()</code> would cause an error, since it can't find a message that has already been deleted.</p>
<p>My proposed solution would be the problem below.</p>
<hr />
<h1>Problem:</h1>
<p>Let's say I have an async function called <code>foo</code>:</p>
<pre class="lang-py prettyprint-override"><code>import asyncio
limit: int
async def foo():
print("bar")
async def foo_caller():
await asyncio.gather(foo(), foo(), foo(), foo(), foo())
await foo()
await foo()
</code></pre>
<p>This function would be called multiple times using the <code>foo_caller</code> function. Currently, this would print <code>bar</code> <strong>7 times</strong>.</p>
<p>The problem is, <strong>How to execute only one function call when <code>foo</code> is called multiple times in a short timeframe?</strong></p>
<p>The solution should print <code>bar</code> only <strong>three times</strong>. One for the <code>await asyncio.gather(foo(), foo(), foo(), foo(), foo())</code>, and one each for the <code>await foo()</code>.</p>

74,402,826 | <p>Please excuse my noobness regarding this language, I am very much a beginner. I've been tasked with creating a Quiz Maker and I'm stuck on how I am supposed to put some of my class elements into a List. The reason I need to put these into a list is because I don't want to handle each user inputted answer separately, rather in a list and have everything dependant on the list size and set a limit for how many answers I want to store in it. Any help would be hugely appreciated.</p>
<p>Here is my class:</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Quiz_Maker
{
public class QuestionAndAnswers
{
public string userQuestion { get; set; }
List<string> QnAList = new List<string>();
public string falseAnswerOne { get; set; } //TODO: this could maybe perhaps possilby be a list of string
public string falseAnswerTwo { get; set; } //TODO: this could maybe perhaps possilby be a list of string
public string falseAnswerThree { get; set; } //TODO: this could maybe perhaps possilby be a list of string
public string correctAnswer { get; set; } //TODO: this could maybe perhaps possilby be a list of string
private int correctAnswerIndex;
}
}
</code></pre>
<p>Here is my object method:</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Quiz_Maker
{
public static class UserInterface
{
public static QuestionAndAnswers GetQuestionAndAnswers()
{
QuestionAndAnswers UserQnA = new QuestionAndAnswers();
string userQuestion;
string correctAnswer;
string falseAnswerOne;
string falseAnswerTwo;
string falseAnswerThree;
Console.WriteLine("Please type your question: ");
UserQnA.userQuestion = Console.ReadLine();
Console.WriteLine("Please type the correct answer: ");
UserQnA.correctAnswer = Console.ReadLine();
Console.WriteLine("Please type your first false answer: ");
UserQnA.falseAnswerOne = Console.ReadLine();
Console.WriteLine("Please type your second false answer: ");
UserQnA.falseAnswerTwo = Console.ReadLine();
Console.WriteLine("Please type your third false answer: ");
UserQnA.falseAnswerThree = Console.ReadLine();
return UserQnA;
}
}
}
</code></pre>
<p>I've googled this topic to death and have not found anything that makes sense.</p>

74,402,881 | <p>I have a view that needs to be displayed with a slanted corner on one side. I've already done it when the view has a background color like this:</p>
<p><a href="https://i.stack.imgur.com/TbMh0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TbMh0.png" alt="enter image description here" /></a></p>
<p>But I also need it to be displayed with a clear background. After setting its background to clear and adding a border to it this is the output:</p>
<p><a href="https://i.stack.imgur.com/mAQIB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mAQIB.png" alt="enter image description here" /></a></p>
<p>Here is the code for the custom view that I'm using to create the diagonal corner:</p>
<pre class="lang-swift prettyprint-override"><code>class PointedView: UIImageView {
@IBInspectable var borderColor: UIColor = UIColor.clear {
didSet {
layer.borderColor = borderColor.cgColor
}
}
@IBInspectable var borderWidth: CGFloat = 0 {
didSet {
layer.borderWidth = borderWidth
}
}
@IBInspectable
/// Percentage of the slant based on the width
var slopeFactor: CGFloat = 15 {
didSet {
updatePath()
}
}
private let shapeLayer: CAShapeLayer = {
let shapeLayer = CAShapeLayer()
shapeLayer.lineWidth = 0
// with masks, the color of the shape layer doesn’t matter;
// it only uses the alpha channel; the color of the view is
// dictate by its background color
shapeLayer.fillColor = UIColor.white.cgColor
return shapeLayer
}()
override func layoutSubviews() {
super.layoutSubviews()
updatePath()
}
private func updatePath() {
let path = UIBezierPath()
// Start from x = 0 but the mid point of y of the view
path.move(to: CGPoint(x: 0, y: bounds.midY*2))
// Create the top slanting line
path.addLine(to: CGPoint(x: bounds.minX, y: bounds.minY))
// Straight line from end of slant to the end of the view
path.addLine(to: CGPoint(x: bounds.maxX, y: bounds.minY))
// Straight line to come down to the bottom, perpendicular to view
path.addLine(to: CGPoint(x: bounds.maxX, y: ((bounds.maxY*3)/4) + 20))
// Go back to the slant end position but from the bottom
path.addLine(to: CGPoint(x: (bounds.maxX*3)/4, y: bounds.maxY))
// Close path back to where you started
path.close()
shapeLayer.path = path.cgPath
layer.mask = shapeLayer
}
}

<p>Is there any possible solution to this?</p>

74,402,886 | <p>I have a dataframe and in one of the columns i have quite a lot of missing data, i tried to impute these values but as there is so much that is missing it doesn't do a very good job. The column in question here has a value given for roughly every 5 years, normally i would just delete it but i want to see if i can salvage something from it. What im looking to go is to carry forward the value provided, filling in the NA until a new value appears. So for example in my data provided im looking for an output like this;</p>
<pre><code>df
Country_Name year gdp_per_capita freshwaster_production_pc
Albania 1997 717.3800 4.543622e-07 #use this value
Albania 1998 813.7894 4.543622e-07
Albania 1999 1033.2425 4.543622e-07
Albania 2000 1126.6833 4.543622e-07
Albania 2001 1281.6598 4.543622e-07

Albania 2004 2373.5813 5.451047e-07
</code></pre>
<p>Im also open to ideas on better ways to deal with this so feel free to suggest anything thats better. I thought about averaging the values and using them but i think this is a better way of showing the changes in time</p>

<p>I have 2 defined records</p>
<ul>
<li>CreateObjectRequest</li>
<li>UpdateObjectRequest</li>
</ul>
<p>that must be verified by an utility method.</p>
<p>As those 2 objects have the same fields, the same verify method can be applied on both types.<br />
Right now I'm just overloading by using 2 methods, but it's verbosy.</p>
<pre class="lang-java prettyprint-override"><code>public record CreateObjectRequest (

}
public void validateRequest(UpdateObjectRequest updateObjectRequest) {
//same long body...

74,403,065 | <p>Suppose a PostgreSQL table, <code>articles</code>, contains two nullable String columns of <code>name</code> and <code>alt_name</code>.
Now, I want to find records (rows) in the table that have</p>
<ul>
<li>a <strong>combination of</strong> String <code>name</code> and <code>alt_name</code> matches another combination of the same type in the same table:
<ul>
<li>i.e., <code>[a.name, a.alt_name]</code> is equal to either <code>[b.name, b.alt_name]</code> or <code>[b.alt_name, b.name]</code></li>
</ul>
</li>
<li>where <code>name</code> or <code>alt_name</code> may be <code>NULL</code> or an empty String, and in any circumstances <code>NULL</code> and an empty String should be treated as identical;
<ul>
<li>e.g., when <code>[a.name, a.alt_name] == ["abc", NULL]</code>, a record of <code>[b.name, b.alt_name] == ["", "abc"]</code> should match, because one of them is <code>"abc"</code> and the other is NULL or empty String.</li>
</ul>
</li>
</ul>
<p>Is there any neat query to achieve this?</p>
<p>I thought if there is a way to concatenate both columns with a UTF-8 <em>replacement character</em> (<code>U+FFFD</code>) in between, where NULL is converted into an empty String, that would solve the problem. Say, if the function were <code>magic_fn()</code>, the following would do a job, providing there is a unique column <code>id</code>:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT * FROM articles a INNER JOIN places b ON a.id <> b.id
WHERE
magic_fn(a.name, a.alt_name) = magic_fn(b.name, b.alt_name)
OR magic_fn(a.name, a.alt_name) = magic_fn(b.alt_name, b.name);
-- [EDIT] corrected from the original post, which was simply wrong.
</code></pre>
<p>However, <a href="https://stackoverflow.com/q/12378904/3577922"><strike>concatnation is not a built-in function in PostgreSQL</strike></a> and I don't know how to do this.<br />
[<strong>EDIT</strong>] As commented by @Serg and in answers, a string-concatnation function is now available in PostgreSQL from Ver.9.1 (<a href="https://www.postgresql.org/docs/current/functions-string.html" rel="nofollow noreferrer">CONCAT or ||</a>); n.b., it actually accepts non-String input as long as one of them is a String-type as of Ver.15.</p>
<p>Or, maybe there is simply a better way?</p>

<p>For example.
If i write 5 in cell B1, I want to sum range A1:A5.
If i write 10 in cell B1, I want to sum range A1:A10.
If i write 20 in cell B1, I want to sum range A1:A20.</p>
<p>And so on.</p>
<p>Does anyone know a formula for this?</p>
<p>Kind regards.</p>
<p>I tried writing( in cell B1) =SUM(A1:A(1+B1)). This didn't work at all, instead a =NAME? appeared.</p>

74,403,187 | <p>I want the image in my site to completely change when the browser is resized.
I've been using media-queries, but I can't seem to get it right. Any thoughts/tips?
The thing is I have tried the display trick with media query but its not working</p>
<p>I did this, but it's not working even when I am lowering the viewport. The image in the laptop viewport remains the same in the phone viewport.</p>

74,403,200 | <p>There are multiple parts of Compose that deal with environment variables in one sense or another. So how do I pass Environment variables in Compose ( docker-compose )</p>
<p>According to the documentation If you have multiple environment variables, you can substitute them by adding them to a default environment variable file named .env or by providing a path to your environment variables file using the --env-file command line option.</p>

74,403,222 | <p>I'am quite new to F#, and was solving some basic exercises when i stumbled upon this function</p>
<ol>
<li>Give the (most general) types of g1 and g2 and describe what each of these two functions
computes. Your description for each function should focus on what it computes, rather
than on individual computation steps</li>
</ol>
<pre class="lang-ml prettyprint-override"><code> let rec g1 p = function
| x::xs when p x -> x :: g1 p xs
| _ -> [];;
</code></pre>
<p>i don't the understand " when p x " part, or how to call the function. can someone please explain what this function takes in as an argument? as just calling the function like that " g1 [1;2;3] " gives me an error.</p>
<p>Tried calling the function, and tried reading some text books to figure it out</p>

<p><code>awk -F, 'NR==FNR {exclude[$1];next} !($1 in exclude)' old.list new.list > changes.list</code></p>
<p>the files I'm working with have been sorted numerically with -n</p>

30620,14,8729,0.021
30690,10,87,0.021
30800,20,97,1.021
</code></pre>
<p>Result</p>
<pre><code>30615,50,874,00.2
30690,10,87,0.021
30800,20,97,1.021
</code></pre>
<p>I'm looking for a way to tweak my command and make awk print lines only if $1 from new.list is not only unique but also > $1 from the last line of the old.list</p>
<p>Expected result:</p>
<pre><code>30690,10,87,0.021
30800,20,97,1.021
</code></pre>
<p>because 30690 and 30800 ($1) > 30620 ($1 from the last line of old.list)
in this case, 30615,50,874,00.2 would not be printed because 30615 is admitedly unique to new.list but it's also < 30620 ($1 from the last line of the old.list)</p>
<p><code>awk -F, '{if ($1 #from new.list > $1 #from_the_last_line_of_old.list) print }'</code></p>
<p>something like that, but I'm not sure it can be done this way?</p>
<p>Thank you</p>

A field that updates every time a row updates in the database, despite where the update comes from: through calling <code>.save()</code> or through <code>queryset.update()</code> or even when updates happen in the database directly and not from the Django app.</p>

other SO questions(like <a href="https://stackoverflow.com/questions/52159958/auto-now-field-is-not-updating-with-updating-using-filter">this</a> and <a href="https://stackoverflow.com/questions/37766018/how-to-create-a-datetimefiled-that-keeps-the-last-edited-time-in-django">this</a>) ask the same thing, update instance at every change not only <code>.save()</code></p>
<p>This problem can be solved using triggers as said <a href="https://stackoverflow.com/questions/1035980/update-timestamp-when-row-is-updated-in-postgresql">here</a> but this way we need to write the same trigger for every modifed_at field in models.</p>
<p>as discussed in <a href="https://code.djangoproject.com/ticket/15566" rel="nofollow noreferrer">this Django ticket</a> this problem will not be addressed and solved in Django. even <a href="https://gist.github.com/anonymous/1872523#L83" rel="nofollow noreferrer">the suggested patch</a> only updates the instance if it changes via Django.</p>
<p>the only way that comes to my mind is to do <a href="https://stackoverflow.com/questions/10924619/setting-database-level-defaults-for-fields-in-django">something like this</a> in a mixin. a mixin that when inherited creates a trigger for fields with auto_now=True. maybe change SQL when Django creates the model creation SQL. but I don't know how to implement this.</p>
<p>so I have two questions:</p>
<ol>
<li>what is the best way to achieve database-level updates for modified_at fields</li>
<li>If my suggested way is the best option how to implement it?</li>
</ol>
<p>I would like to have a database-agnostic solution but FYI currently I'm using PostgreSQL.</p>

74,403,293 | <p>I want to create a function to find the lowest value within a set of numbers, but I do not wish to use the Math.min(); method. Below is my code I have constructed:</p>
<pre><code>function min(arr) {
var lowest = arr.sort((x, y) => x - y);
return lowest[0];
}
</code></pre>
<p>but 'arr.sort' is not a function, as it has not been defined for obvious reasons: I want to be able to input <em>any</em> array into the 'min' function.</p>
<p>I tried creating a JavaScript function for finding the lowest value in an array of numbers, expecting to have a function that would accept any array and would output the lowest value in that array.</p>

74,403,326 | <p>I'm trying to set up a Functions class that will handle functions for my NN projects.
I've figured out I'd like the list of functions to be somewhat flexible (easily add, or remove functions used).</p>
<p>I've created a list of functions, defined a bunch of lambda functions,
added a method that adds all the functions in the body to the list.
When I try to check the length of the list it shows the correct number, but when I try to retrieve a function into a variable and pass it an argument I get an information that lambda takes 1 argument and I gave it 2. I don't understand what is the second argument.</p>
<pre><code>
import numpy as np
class Functions():
f0 = identity = lambda x: x
f1 = linear_step = lambda x: 1 if x > 0 else 0
f2 = sigmoid = lambda x: 1/(1+np.exp(-x))
f3 = tanh = lambda x: np.tanh(x)
f4 = swish = lambda x: x/(1+np.exp(-x))
f5 = absolute = lambda x: abs(x)
f6 = cubic = lambda x: x**3
f7 = square = lambda x: x**2
f8 = sinusoid = lambda x: np.sin(x)
f9 = square_root = lambda x: np.sqrt(x)
f10 = cubic_root = lambda x: np.cbrt(x)
f11 = opposite = lambda x: -x
f12 = inverse = lambda x: 1/x
f13 = exponential = lambda x: np.exp(x)
def __init__(self): #constructor
self._functions = []
self.add_functions(self.f0, self.f1, self.f2, self.f3, self.f4, self.f5, self.f6, self.f7, self.f8, self.f9, self.f10, self.f11, self.f12, self.f13)
#add a fyunction to the list, if it is not already there
def _add_function(self, function):
if function not in self._functions:
self._functions.append(function)
#print(f"Added function: {function.__name__}")
return True
else:
#print(f"Function: {function.__name__} already exists at index: {functions.index(function)}")
return False
#add multiple functions to the list
def add_functions(self, *args):
for function in args:
self._add_function(function)
#get the number of functions in the list
def number_of_functions(self):
return len(self._functions)
#return the function at the given index
def get_function(self, index):
try:
return self._functions[index]
except IndexError:
print("Index out of range");
return None
def get_all_functions(self):
return self._functions
functs = Functions()
print(f"number of functions {functs.number_of_functions()}")
iden = functs.get_function(0)
print(f"identity of one is {iden(1)}")
</code></pre>
<p>What's causing the issue? Alternatively what would be a better way to have an enumerable data structure to store and load the activation functions?</p>

74,403,337 | <p>The __index of the table originally set a meta table, and the actual access is to the function under this meta table.</p>
<p><code>setmetatable(flatTbl, {__index = metaTbl}</code></p>
<p>I want to access the function of the same name of the meta table when the field of the table is not accessible, but I have used two methods without success</p>
<pre><code>function FlatBufferTools:SetMeta(flatTbl)
setmetatable(flatTbl, {
__index = function(tbl, key)
metaTbl = getmetatable(tbl).__index
return metaTbl[key](metaTbl)

function FlatBufferTools:SetMeta2(flatTbl)
metaTbl = getmetatable(flatTbl).__index
setmetatable(metaTbl, {
__index = function(tbl, key)
return tbl[key](tbl)
end
})
end
</code></pre>
<p>The first method is to reset the <code>__index</code> of the table, but the <code>metaTbl</code> that i get is a function</p>
<p>The second method is to set <code>__index</code> to the table's meta table(<code>metaTbl</code>), but the setmetatable function skips it</p>
<p>I checked the <code>metaTbl</code> and there is no <code>__metatable</code></p>

74,403,352 | <p>I am trying to use Python to automate a number of work processes that primarily take place in an online content management system, and to access the CMS, I need to be logged into my work profile on Chrome. While I could sign in once Chromedriver is open, I would have to approve the login on my authenticator each time, somewhat defeating the purpose of automation.</p>
<p>I am using the following code for opening Chromedriver and attempting to load my regular Chrome profile. However, while the rest of the code works as intended, it does not load my profile and I am unsure why.</p>
<pre><code>from selenium import webdriver

driver.get("https://myaccount.google.com/")
while(True):
pass

74,403,355 | <p>Folks, I am new to Next.js 13.</p>
<p>I have created a project using Next.js 13 and playing around with the new <code>app</code> directory.</p>
<p>I am trying to apply styling using Tailwind CSS. I have followed the Next.js documentation below:</p>
<p><a href="https://beta.nextjs.org/docs/styling/tailwind-css" rel="nofollow noreferrer">https://beta.nextjs.org/docs/styling/tailwind-css</a></p>
<p>The documentation says to import the <code>global.css</code> stylesheet to the root layout (<code>app/layout.js</code>) in order to apply the styles to every route in your application. I tried to follow this step, but I am getting the following error:</p>
<p><a href="https://i.stack.imgur.com/gh4tv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gh4tv.png" alt="enter image description here" /></a></p>
<p>Here is my folder structure:</p>
<p><a href="https://i.stack.imgur.com/wuFUf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wuFUf.png" alt="enter image description here" /></a></p>
<p>Here are my code snippets:</p>
<p>app/layout.js</p>
<pre><code>import React from "react";
import Link from "next/link";
import "../styles/global.css";
const Layout = ({ children }) => {
return (

74,403,374 | <p>my code looks like this:</p>
<pre><code>library(tidyverse)
df <- read.table(header=TRUE, text='
subject sex control q1 q2
1 M 7.9 1 1
2 F 6.3 2 3
3 F 9.5 3 1
4 M 11.5 7 6
')
df %>% mutate_all(~case_when(
. == 1 ~ 7,
. == 7 ~ 1,
TRUE ~ . )
)
</code></pre>
<p>I want to replace all 1 with 7 and vice versa but keep everything else.</p>
<p>The error states:</p>
<blockquote>
<p>Error: Problem with <code>mutate()</code> column <code>subject</code>.
i <code>subject = (structure(function (..., .x = ..1, .y = ..2, . = ..1) ...</code>.
x must be a double vector, not an integer vector.</p>
</blockquote>
<p>A solution indicates
<code>TRUE ~ as.numeric(as.character(.)) )</code>
works, but then the sex colum is NA</p>
<p>How can I fix this?</p>
<p>Edit (add):
A suggestion was to use nested if-else, which would work, but I really hope there is a better solution than:
<code>df %>% mutate_all(~ifelse(. == 1, 7, ifelse(. == 7, 1, .)))</code></p>
<p>imagine a long list of values to be replaced.</p>

74,403,387 | <ul>
<li>I pull data from multiple excel and write it back to an aggregated excel file</li>
</ul>
<p>so I have a list of tuples and each tuple consists of two values like this:</p>
<pre><code>tuple = (entity-ID, debitor-name)
list = [tuple1, tuple2, ..., tupleN]
</code></pre>
<p>So it can happen that there are multiple entries with the same debitor-name but with different entity-ID. I want to find all entries where the debitor-name is equal and then merge the diffrent entity-IDs into a list. Context is that there are multiple entities within my company who can all have a credit relation to the same debitor-name.
I hope this is understandable.</p>
<pre><code>for deb in debitor_list:
if deb not in agg_debitor_list:
agg_debitor_list.append(deb)
</code></pre>
<p>This already filters for double entries within a certain entity so for example my debitor_list has following entries:
<code>[("1", "X AG"), ("1", "X AG"), ("1", "Z AG"), ("2", "X AG"), ("2", "X AG")]</code>
it gives me <code>[("1", "X AG"), ("1", "Z AG"), ("2", "X AG")]</code>
as result I need something like this <code>[(["1", "2"], "X AG"), (["1"], "Z AG")]</code> to write in back in the aggregated excel file.</p>

<pre><code>v1 <- c("R", "H", "K") # * (asterisk sign)
v2 <- c("D", "E") # + (plus sign)

x2 <- "KMRDFRHRAE"

# v2_count = 2
# v3_count = 1

<p>So any character that belongs to the vector will be counted as a single count.</p>

74,403,510 | <p>I am trying to build a simple video game engine using C#. This is a long time project, which I only want to do out of interest. For the beginning I wanted to implement a math library for linear algebra. I am just a hobby programmer and I am unsure how to make my code as maintainable as possible in the long term. The following questions represent only examples of a problem, which I assume to have a lot more often in this project. <strong>I ask this question with the hope to structure my project properly from the beginning to keep it easy to test and to maintain.</strong></p>
<p><strong>What is the best way to define repeating methods like for example the dot product for vector classes of different dimensions?</strong></p>
<p>The first implementation I made was to hard code the methods for all vector classes:</p>
<pre><code>class Vector2 {
public float X { get; }
public float Y { get; }
// Operations
public static float Dot(Vector2 a, Vector2 b) => a.X * b.X + a.Y * b.Y;
...
}
class Vector3 {
public float X { get; }
public float Y { get; }
public float Z { get; }
// Operations
public static float Dot(Vector3 a, Vector3 b) => a.X * b.X + a.Y * b.Y + a.Z * b.Z;
...
}
</code></pre>
<p>The code is simple, but it doesn't take advantage of the pattern behind the dot product. I would have to do this for all the other vector operations (addition, scalar multiplication, etc.). It is redundant and opens room for errors.</p>
<p>An alternative approach would be to define the vector operations once in a base class and to put the vector values in an indexer. In this approach, I would only need to define the abstract method for the indexer in the subclasses:</p>
<pre><code>class abstract Vector {
// Indexer
public float this[int index] values { get => GetValueByIndex(index) };
protected abstract float GetValueByIndex(int index);
// Operations
public static float Dot(Vector a, Vector b) {
float DotProduct = 0;
for (int i = 0; i < values.Length; i++){
DotProduct += a[i] * b[i];
}
return DotProduct;
}
...
}
class Vector2 : Vector {
public float X { get; }
public float Y { get; }
protected override float GetValueByIndex(int index) {
if (index == 0) return X;
if (index == 1) return Y;
throw new ArgumentOutOfRangeException("index must be 0 or 1");
}
}
class Vector3 : Vector {
public float X { get; }
public float Y { get; }
public float Z { get; }
protected override float GetValueByIndex(int index) {
if (index == 0) return X;
if (index == 1) return Y;
if (index == 2) return Z;
throw new ArgumentOutOfRangeException("index must be 0, 1 or 2");
}
}
</code></pre>
<p>The hard coding approach should run faster, which is good considering it should be used for a game engine, but it is also opens more room for error. The base class approach is easier to maintain, but the for loops and conditions would make all calculations slower.</p>
<p><strong>Which approach would you prefer or is there an alternative, which allows to get fast and maintainable code at the same time?</strong></p>

74,403,513 | <p>How to sync an action of many microservices and return a single response to the client that takes into consideration each microservice's response?</p>
<p>I'm making a social network application (like Facebook) with microservices, for learning purposes. I've divided the app into following microservices, each will have its own database:</p>
<ol>
<li><p>Authentication - Login/Register, returns a JWT token.
Database stored properties are: UserName, Email, PasswordHash, PasswordSalt.</p>
</li>
<li><p>UserProfiles - Gets and Updates profiles.
Database stored properties are: UserName, FirstName, LastName, Gender, Photos</p>
</li>
<li><p>UserPosts - user can publish Posts with anything he likes, others can comment.
Database stored properties are: UserName, UserPosts, Comments</p>
</li>
<li><p>Gateway - collects http requests from clients, forwards them to correct microservices</p>
</li>
</ol>
<p>THere will be more, like Messages between users.</p>
<p>Some properties in databases will duplicate (UserName, but there can be more). I suppose I cannot avoid that if I want to make the services independent.</p>
<p>Now, what do I do if the user decides to change a shared property, like UserName? Obviously it will require every service to update its database. But what if one of services cannot connect to the database or meets some other error? The response should be 500 Internal Server Error. I can see two options for that:</p>
<ol>
<li>Make the Gateway send an HTTP request to each microservice, requesting an update. How do I pass information about an error in one of the services? This seems a bad approach</li>
<li>Publish a message (MassTransit, RabbitMQ) to all microservices with update request. This way I can await a response from each service and decide what to return to client. But who should be the publisher here? Gateway? Authentication?</li>
</ol>
<p>Is there some other way I have not thought about? I'll be thankful for any good-practice, clean-code advices.</p>
<p>Thank you</p>
<p>I tried messaging services from Authentication services, since it's the one that creates the User entity in the first place. But it doesn't feel like a good reason to make it there.</p>

74,403,545 | <p>Basically the title. Is there a relatively fast way to modify all, or a bunch of elements of a vector by a given value, for eg. 1? If not, is there some other datatype that would perform this kind of an operation better?</p>
<p>I have implemented a for loop that basically adds 1 to every element of a vector. Is there some cleaner/shorter way to go about this?</p>

for (int i = 0;i<10;i++){
vct.push_back(i);
}
for (int i = 0;i<vct.size();i++){

<p>If a new task is received for group A, the algorithm would pick John, since he has 1 task only.
If a new task is received for group B, the algorithm would pick Back, since he has 1 task only.
If a new task is received for group C, how can we pick one using order ASC since they both have 2 tasks?</p>
<p>Anybody has any idea how to do it?</p>
<p>Thank you</p>

74,403,613 | <p>I'm trying to come up with a SP that creates a certain task, appended by year, for a generic approach.
I can create the tasks outside, alone, with the $$ marks,
but I can't do it inside JS SP like this:</p>
<pre><code>CREATE OR REPLACE PROCEDURE create_exec_tasks_by_year_range()
RETURNS varchar
LANGUAGE JAVASCRIPT
EXECUTE AS OWNER
AS
$$
var return_value = "";
var range_years = Array.from(Array(new Date().getUTCFullYear() - 2006), (_, i) => (i + 2007).toString());
//CREATE a task TO CALL SP BY YEAR, FROM 2007-current year
range_years.forEach((year_elem) => {
rs = snowflake.createStatement( {
sqlText: `CREATE OR REPLACE TASK MY_TSK_YEAR_`+year_elem+`
SCHEDULE = 'USING CRON 30 22 * * SUN UTC'
AS
EXECUTE IMMEDIATE
$$
DECLARE
year_track float;
rs resultset;
BEGIN
year_track := :1;
rs := (execute IMMEDIATE 'INSERT INTO MY_TABLE VALUES(?)' using (year_track));
return TABLE(rs);
END;
$$
;`
, binds: [year_elem] }).execute();
rs.next();
//rs.getColumnValue(1);
return_value += "MY_TSK_YEAR_"+year_elem+", ";
to_exec = snowflake.createStatement( {
sqlText: `EXECUTE TASK MY_TSK_YEAR_`+year_elem+`
to_exec.next();
return_value += to_exec.getColumnValue(1)+", ";
});
return return_value;
$$;
</code></pre>
<p>because it throws me</p>
<pre><code>syntax error line ...at position 2 unexpected 'DECLARE'
</code></pre>
<p>while creating the TASK manually, works, because I don't have a conflict between $$?</p>
<pre><code>CREATE OR REPLACE TASK SHARED.SRC_EXT_WEATHER.TSK_DUMMY
SCHEDULE = 'USING CRON 30 22 * * SUN UTC'
AS
EXECUTE IMMEDIATE
$$
DECLARE
year_track float;
rs resultset;
BEGIN
year_track := 2007;
rs := (execute IMMEDIATE 'INSERT INTO MY_TABLE VALUES(?)' using (year_track));
return TABLE(rs);
END;
$$;
</code></pre>
<p>Is it possible to make the SP to work for the TASK created with EXECUTE_IMMEDIATE block and bind parameter? The problem seems to be the way I write in inside the $$ scope of the stored procedure, no?</p>

74,403,620 | <p>I have a Google CloudRun Service, that is can be accessed either by the CloudRun URL or by a custom domain via a Load Balancer in the Google Cloud.</p>
<p>Now I am trying to setup some kind of access control, so that the Service which run the Development Stage can only be accessed by logged-in developers.</p>
<p>So far I tried to set the Trigger Configuration of the CloudRun Service to authentication required. That works for the base CloudRun URL, but on adding a path to the base URL I get a Forbidden error, even if I could access the base URL. And Accessing the Service via the LoadBalancer always gives a Forbidden.</p>
<p>Is there a way to make the CloudRun Service Accessible (including different Paths) only to LoggedIn Developers?</p>
<p>And also is there a way to make the Service only accessible by the LoadBalancer URL and not the CloudRun URL?</p>

74,403,648 | <p>I'm currently working on a project, which includes a website, built and run by Django. On this website, I'm trying to load data through fast API and try to load this data through JavaScript and the Fetch API. But I always get instead of the Data provided through the API, an [object Promise]. I've tried many different methods but none seem to work.</p>
<p>I've tried for example:</p>
<pre><code>document.getElementById("1.1").innerHTML = fetch('the URL')
.then(response => response.text())
</code></pre>
<p>or</p>
<pre><code>document.getElementById("1.1").innerHTML = fetch('the URL')
.then(response => response.text())
.then((response) => {
console.log(response)
})
</code></pre>
<p>and many other methods. I've also checked and the API request works perfectly, returning a string.</p>

74,403,684 | <p>since the last update of the Logicmonitor provider in Terraform we're struggling with a sorting isse.</p>
<p>In LogicMonitor the properties of a device are a name-value pair, and they are presented alfabetically by name. Also in API requests the result is alphabetical. So far nothing fancy.</p>
<p>But... We build our Cloud devices using a module. Calling the module we provide some LogicMonitor properties specially for this device, and a lot more are provided in the module itself.</p>
<p>In the module this looks like this:
`</p>
<pre><code>custom_properties = concat([
{
name = "host_fqdn"
value = "${var.name}.${var.dns_domain}"
},
{
name = "ocid"
value = oci_core_instance.server.id
},
{
name = "private_ip"
value = oci_core_instance.server.private_ip
},
{
name = "snmp.version"
value = "v2c"
}
],
var.logicmonitor_properties)
</code></pre>
<p>`</p>
<p>The first 4 properties are from the module and combined with anyting what is in var.logicmonitor_properties. On the creation of the device in LogicMonitor all properties are set in the order the are and no problem.</p>
<p>The issue arises when there is any update on a terraform file in this environment. Due to the fact the properties are presented in alphabetical order, Terraform is showing a lot of changes if finds (but which are in fact just a mixed due to sorting).</p>
<p>The big question is: How can I sort the complete list of properties bases on the "name".</p>
<p>Tried to work with maps, sort and several other functions and examples, but got nothing working on key-value pairs. Merging single key's works fine in a map, but how to deal with name/value pairs/</p>

74,403,748 | <p>We have a scenario where we need to migrate more than a 100 projects that are in one ADO organization to another ADO organization.</p>
<p>Is there way how to do perform this migration org to org?</p>
<p>We have tried using the Azure migration devops tool by installing it in DEV test lab in A tenant and installed the tool.
Started with workitem migration but couldn't due to the errors.
So is there a way out to directly migrate org to org in two different ADO's?</p>

74,403,756 | <p>I have created a tibble consisting of 6 columns containing 6 different variables that will be input for a user defined function. I am new to r, and I don't know how to connect the tibble with user defined function. Please help.</p>
<p>I have replaced the complex user defined function with simple <code>user_defined_function</code> for the sake of discussion.
`</p>
<pre><code>library(tidyr)
library(dplyr)
rgb_val <- seq(from=0, to=255, by=10)
rgb_grid <- expand_grid(r1 = rgb_val, g1 = rgb_val, b1 = rgb_val,
r2 = rgb_val, g2 = rgb_val, b3 = rgb_val)
user_defined_function <- function(x) {
x[,1] + x[,2] + x[,3] + x[,4] + x[,5] + x[,6]
}
rgb_grid %>% mutate(new_cols = user_defined_function ())
</code></pre>
<p>I want the results of the <code>user_defined_function</code> to be added as new column to the tibble <code>rgb_grid</code>. However, if what I have tried, unsuprisingly, throws an error.</p>

74,403,784 | <p>A <code>Collector</code> has three generic types:</p>
<pre><code>public interface Collector<T, A, R>
</code></pre>
<p>With <code>A</code> being <em>the mutable accumulation type of the reduction operation (often hidden as an implementation detail)</em>.</p>
<p>If I want to create my custom collector, I need to create two classes:</p>
<ul>
<li>one for the custom accumulation type</li>
<li>one for the custom collector itself</li>
</ul>
<p>Is there any library function/trick that takes the accumulation type and provides a corresponding Collector?</p>
<h3>Simple example</h3>
<p>This example is extra simple to illustrate the question, <strong>I know I could use <code>reduce</code> for this case, but this is not what I am looking for</strong>. Here is a <a href="https://stackoverflow.com/a/74401856/7424948">more complex example</a> that sharing here would make the question too long, but it is the same idea.</p>
<p>Let's say I want to collect the sum of a stream and return it as a <code>String</code>.</p>
<p>I can implement my accumulator class:</p>
<pre><code>public static class SumCollector {
Integer value;
public SumCollector(Integer value) {
this.value = value;
}
public static SumCollector supply() {
return new SumCollector(0);
}
public void accumulate(Integer next) {
value += next;
}
public SumCollector combine(SumCollector other) {
return new SumCollector(value + other.value);
}
public String finish(){
return Integer.toString(value);
}
}
</code></pre>
<p>And then I can create a <code>Collector</code> from this class:</p>
<pre><code>Collector.of(SumCollector::supply, SumCollector::accumulate, SumCollector::combine, SumCollector::finish);
</code></pre>
<p>But it seems strange to me that they all refer to the the other class, I feel that there is a more direct way to do this.</p>
<p>What I could do to keep only one class would be <code>implements Collector<Integer, SumCollector, String></code> but then every function would be duplicated (<code>supplier()</code> would return <code>SumCollector::supply</code>, etc).</p>

74,403,825 | <p>Sorry I'm struggling with something that should be simple.</p>
<p>I have table "Risks_For_Task_1":</p>
<pre><code>+--------------+-------------+--------------+
| RiskName | Mitigation | RiskLevel |
+--------------+-------------+--------------+
| Risk A | Mitigate#1 | Medium |
| Risk B | Mitigate#2 | Low |
| Risk C | Mitigate#3 | High |
+--------------+-------------+--------------+
</code></pre>
<p>And a table "Risks_For_Task_2":</p>
<pre><code>+--------------+-------------+--------------+
| RiskName | Mitigation | RiskLevel |
+--------------+-------------+--------------+
| Risk D | Mitigate#4 | Low |
| Risk E | Mitigate#5 | Low |
| Risk F | Mitigate#6 | Medium |
+--------------+-------------+--------------+
</code></pre>
<p>And a table "Risks_For_Task_3":</p>
<pre><code>+--------------+-------------+--------------+
| RiskName | Mitigation | RiskLevel |
+--------------+-------------+--------------+
| Risk G | Mitigate#7 | Medium |
| Risk H | Mitigate#8 | High |
| Risk I | Mitigate#9 | Medium |
+--------------+-------------+--------------+
</code></pre>
<p>And a table "Tasks":</p>
<pre><code>+--------------+-------------+
| ID | TaskName |
+--------------+-------------+
| 1 | Task#1 |
| 2 | Task#2 |
| 3 | Task#3 |
+--------------+-------------+
</code></pre>
<p>I wish to combine Risks_For_Task_1, Risks_For_Task_2, and Risks_For_Task_3, and put them into an existing table called "Task_Risks" with an extra column referencing the ID from the table Tasks. So the result should look like this:</p>
<pre><code>+--------------+-------------+--------------+--------------+
| RiskName | Mitigation | RiskLevel | TaskID |
+--------------+-------------+--------------+--------------+
| Risk A | Mitigate#1 | Medium | 1 |
| Risk B | Mitigate#2 | Low | 1 |
| Risk C | Mitigate#3 | High | 1 |
| Risk D | Mitigate#4 | Low | 2 |
| Risk E | Mitigate#5 | Low | 2 |
| Risk F | Mitigate#6 | Medium | 2 |
| Risk G | Mitigate#7 | Medium | 3 |
| Risk H | Mitigate#8 | High | 3 |
| Risk I | Mitigate#9 | Medium | 3 |
+--------------+-------------+--------------+--------------+
</code></pre>
<p>This is what I wrote:</p>
<pre><code>INSERT INTO Task_Risks (RiskName, Mitigation, RiskLevel, TaskID)
Select RiskName, Mitigation, RiskLevel, TaskID from
((Select RiskName, Mitigation, RiskLevel from Risks_For_Task_1
Full Join
Select ID from Tasks where TaskName='Task#1')
Union All
(Select RiskName, Mitigation, RiskLevel from Risks_For_Task_2
Full Join
Select ID from Tasks where TaskName='Task#2')
Union All
(Select RiskName, Mitigation, RiskLevel from Risks_For_Task_3
Full Join
Select ID from Tasks where TaskName='Task#3'));
</code></pre>
<p>Above code gives the error "invalid table name".</p>

74,403,919 | <p>I have a problem with sorting function.</p>
<p>I have following struct:</p>
<pre><code>struct Object {
int value, height;
Object(int v, int h) {
this->value = v;
this->height = h;
}
};
</code></pre>
<p>I am storing vector of this objects: <code>std::vector<Object> v</code></p>
<p>And I'd like to sort it such that if the height is greater than some <code>i</code> then it should go at the end, and if it is less or equal sort by value.</p>
<p>I've tried this before:</p>
<pre><code>// some value
int i = 4;
std::sort(v.begin(), v.end(), [ & ](Object a, Object b) {
if (b.height > i) {
return false;
}
if (a.height > i) {
return false;
}
return a.value > b.value;
});
</code></pre>
<p>But it does not seem to work..</p>
<p>When I have these elements:</p>
<p><code>std::vector<Object> v = {{3, 10}, {5, 2}, {3, 2}, {2, 10}, {2, 1000000000}};</code> and <code>i = 2</code></p>
<p>When I print values of v, after sorting I see that they appear in the exact same order</p>
<p>And I'd like them in the following order:
<code>{{5, 2}, {3, 2}, {3, 10}, {2, 10}, {2, 1000000000}}</code></p>

</div>
<ul>
<li>"ID" is an identity field.</li>
<li>Rank is an always increasing integer that does the same job as "Tag"</li>
<li>"Tag" groups rows together into Single or Multiple type rows: if "Tag" is blank or null the row is selected by itself (single). If 'A', 'B' 'C' or 'D' they must all be rolled up to one 'A' (Multiple) row by concatenating the "Name" fields separated by commas.</li>
<li>The "Size" value for the rolled-up rows is the value for the 'A' row. For all rows with 'B','C' or 'D' Size is zero and on rollup will take on the previous 'A' value.</li>
<li>Finally, the Seq field is a user-specified sort order value the final ORDER BY Field.</li>
</ul>
<p>So, I need the following output:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Tag</th>
<th>Name</th>
<th>Size</th>

<tr>
<td>A</td>
<td>Two,Three,Four</td>
<td>12</td>
</tr>
<tr>
<td></td>
<td>One</td>
<td>14</td>
</tr>
</tbody>
</table>
</div>
<p>I know I need sub queries and some combinations of GROUP BY and/or PARTITION BY, plus ROW_OVER to roll up the rows. I've tried all combinations I can think of with no success. There must be TSQL query to do this without resorting to cursors. Can anyone help? Thanks in advance.</p>

<p>I am having a problem where the values in my datasets are getting cut off because they are too long.

74,404,106 | <p>I have been looking through some legacy code and found this little snippet:</p>
<pre><code>std::vector<int>** grid = new std::vector<int>*[10];
for (int k = 0; k < 10; k++)
grid[k] = new std::vector<int>[10];
</code></pre>
<p>And then later on, the original developer is calling this command here:</p>
<pre><code>grid [i][j].push_back(temp);
</code></pre>
<p>I was under the impression that the <code>[i][j]</code> would return the value in the nested vector, but by using <code>push_back</code> implies that there is a pointer to a vector at that location? I'm confused where this third vector arises from.</p>
<p>Also, is there a better approach? would a triple nested vector also achieve the same results as the above code?</p>
<p>Thanks in advance!</p>

74,404,150 | <p>My GCP cloud SQL has SSL enabled. With that, my client will require the server CA cert, client cert and key to connect to the database. The client is configured to retrieve the certs and key from Secret Manager.</p>
<p>I am deploying my setup using Terraform. Once the SQL instance is created, it needs to output the certs and key so that I can create them in Secret Manager. However, Secret Manager only takes in string format but the output of the certs and keys are in list format.</p>
<p>I am quite new to Terraform, what can I do to import the SQL certs and key into Secret Manager?</p>
<p>The following are my Terraform code snippets:</p>
<p><strong>Cloud SQL</strong></p>
<pre><code>output "server_ca_cert" {
description = "Server ca certificate for the SQL DB"
value = google_sql_database_instance.instance.server_ca_cert
}
output "client_key" {
description = "Client private key for the SQL DB"
value = google_sql_ssl_cert.client_cert.private_key
}
output "client_cert" {
description = "Client cert for the SQL DB"
value = google_sql_ssl_cert.client_cert.cert
</code></pre>
<p><strong>Secret Manager</strong></p>
<pre><code>module "server_ca" {
source = "../siac-modules/modules/secretManager"
project_id = var.project_id
region_id = local.default_region
secret_ids = local.server_ca_key
# secret_datas = file("${path.module}/certs/server-ca.pem")
secret_datas = module.sql_db_timeslot_manager.server_ca_cert
}
</code></pre>
<p><strong>Terraform plan error</strong>
Error: Invalid value for input variable

74,404,167 | <p>I made a regex to extract values from a templated string. The regex is working smooth on websites like regexr.com but it's failing when I try to run in shell.</p>
<p>As example, let's use those lines:</p>
<blockquote>
<p>[2022-11-11T12:07:00.789Z] "GET /check?subject=johnbegucci HTTP/1.1" 200 - "-" 0 17 3 2 "-" "-" "4e4c4fb1-a4d8-4075-8e42-b5fb9216f863" "laundry.transaction.svc.cluster.local:4466" "172.16.107.246:4466" outbound|4466||laundry.transaction.svc.cluster.local 172.16.67.246:51630 10.100.111.246:4466 172.16.67.246:48610 - default</p>
<p>[2022-11-11T13:31:41.189Z] "GET /v1/campaign/198237-jsd-1231 HTTP/1.1" 200 - "-" 0 674 63 63 "-" "Apache-HttpClient/4.5.10 (Java/11.0.7)" "9b3afd5b-c092-4e84-9f29-6380b7f2cafc" "mkt-extractor.mkt-extractor" "172.16.108.138:80" outbound|80||mkt-extractor.mkt-extractor.svc.cluster.local 172.16.65.24:57134 10.100.19.249:80 172.16.65.24:38816 - default</p>
</blockquote>
<p>Both lines follows the pattern:</p>
<blockquote>
<p>[%START_TIME%] "%REQ(:METHOD)% %REQ(X-ENVOY-ORIGINAL-PATH?:PATH)% %PROTOCOL%" %RESPONSE_CODE% %RESPONSE_FLAGS% %BYTES_RECEIVED% %BYTES_SENT% %DURATION% %RESP(X-ENVOY-UPSTREAM-SERVICE-TIME)% "%REQ(X-FORWARDED-FOR)%" "%REQ(USER-AGENT)%" "%REQ(X-REQUEST-ID)%" "%REQ(:AUTHORITY)%" "%UPSTREAM_HOST%" %UPSTREAM_CLUSTER% %UPSTREAM_LOCAL_ADDRESS% %DOWNSTREAM_LOCAL_ADDRESS% %DOWNSTREAM_REMOTE_ADDRESS% %REQUESTED_SERVER_NAME%\n</p>
</blockquote>
<p>Based on that, I created this regex to extract values from <code>UPSTREAM_HOST</code>. Values like <code>outbound|4466||laundry.transaction.svc.cluster.local</code>:</p>
<pre><code>(\[.*\])\s(\".*\")\s([0-9]*)\s(.*)\s(\".*\")\s([0-9]*)\s([0-9]*)\s([0-9]*)\s([0-9]*)\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)+
</code></pre>
<p>I have tested this regex on website regexr.com and it displays right values as group 14 for both lines:</p>
<pre><code>outbound|4466||laundry.transaction.svc.cluster.local
outbound|80||mkt-extractor.mkt-extractor.svc.cluster.local
</code></pre>
<p>After that, I tried to execute an <code>awk -v FPAT</code> but the groups looks wrong. To get values from <code>UPSTREAM_HOST</code>, I need to change print value and it's not viable because I'm creating an automation to process log:</p>
<pre><code>echo '[2022-11-11T12:07:00.789Z] "GET /check?subject=johnbegucci HTTP/1.1" 200 - "-" 0 17 3 2 "-" "-" "4e4c4fb1-a4d8-4075-8e42-b5fb9216f863" "laundry.transaction.svc.cluster.local:4466" "172.16.107.246:4466" outbound|4466||laundry.transaction.svc.cluster.local 172.16.67.246:51630 10.100.111.246:4466 172.16.67.246:48610 - default' | awk -v FPAT='(\[.*\])\s(\".*\")\s([0-9]*)\s(.*)\s(\".*\")\s([0-9]*)\s([0-9]*)\s([0-9]*)\s([0-9]*)\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)+' -v OFS='|' '{print $15}'
# above example im using '{print $15}'
echo '[2022-11-11T13:31:41.189Z] "GET /v1/campaign/198237-jsd-1231 HTTP/1.1" 200 - "-" 0 674 63 63 "-" "Apache-HttpClient/4.5.10 (Java/11.0.7)" "9b3afd5b-c092-4e84-9f29-6380b7f2cafc" "mkt-extractor.mkt-extractor" "172.16.108.138:80" outbound|80||mkt-extractor.mkt-extractor.svc.cluster.local 172.16.65.24:57134 10.100.19.249:80 172.16.65.24:38816 - default' | | awk -v FPAT='(\[.*\])\s(\".*\")\s([0-9]*)\s(.*)\s(\".*\")\s([0-9]*)\s([0-9]*)\s([0-9]*)\s([0-9]*)\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(\".*\")\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)\s(.*)+' -v OFS='|' '{print $18}'
# above example im using '{print $18}'
</code></pre>
<p>Is there any way to make it work for both logs with same <code>print</code> position?</p>

74,404,178 | <p>I'm new at python. I struggle how to count how many people have died from each country. I use pandas dataframe. 0 - means that person died, 1 - survived. I have ~2000rows.
Maybe it is not enough info, but I dont know how to solve this and from what exactly to start...</p>
<pre><code>df['survived'] = df['survived'].replace(['no'], 0)
df['survived'] = df['survived'].replace(['yes'], 1)
countries_list = list(df['country'])
survived_list = list(df['survived'])
for i in range(len(survived_list)):
print(f'{survived_list[i]}: {countries_list[i]}')
</code></pre>
<p>I only get to this point and dont know what to do. With IF statement I also get nowhere:
If i write like this (below) it shows me an error I dont know why. I hope that you get the idea what I want to do. Thank you in advance</p>

74,404,207 | <p>I have a pandas dataframe below,</p>
<pre><code>data = {'Team': ['Riders', 'Riders', 'Devils', 'Devils', 'Kings',
'kings', 'Kings', 'Kings', 'Riders', 'Royals', 'Royals', 'Riders'],
'Rank': [1, 2, 2, 3, 3,4 ,1 ,1,2 , 4,1,2],
'Year': [2014,2015,2014,2015,2014,2015,2016,2017,2016,2014,2015,2017],
'Points':[876,789,863,673,741,812,756,788,694,701,804,690]}
df = pd.DataFrame(data)
</code></pre>
<p>Here df is a Pandas dataframe.</p>
<p>I am trying to convert this dataframe to pandas API on spark</p>
<pre><code>import pyspark.pandas as ps
pdf = ps.from_pandas(df)
print(type(pdf))
</code></pre>
<p>Now the dataframe type is '<class 'pyspark.pandas.frame.DataFrame'>
'
No I am applying group by function on pdf like below,</p>
<pre><code>for i,j in pdf.groupby("Team"):
print(i)
print(j)
</code></pre>
<p>I am getting an error below like</p>
<pre><code>KeyError: (0,)
</code></pre>
<p>Not sure this functionality will work on pandas API on spark ?</p>

74,404,227 | <p>In Google Sheets I have the following formula:</p>
<pre><code>=IF(REGEXMATCH(B1;"offers");"spring";0)
</code></pre>
<p>If the cell B1 contains the text "offers" the output will be "spring", otherwise the output will be "0". This works fine but now I want the formular to look at B1 and C1 and if either of them contains "offers" the output should be "spring".</p>
<p><strong>Example Output with formula in column D:</strong></p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>B</th>
<th>C</th>
<th>D</th>
</tr>
</thead>
<tbody>
<tr>
<td>test offers test</td>
<td>lorem ipsum</td>
<td>spring</td>
</tr>
<tr>
<td>lorem ipsum</td>
<td>test offers test</td>
<td>spring</td>
</tr>
<tr>
<td>lorem ipsum</td>
<td>lorem ipsum</td>
<td>0</td>
</tr>
</tbody>
</table>
</div>
<p>I tried the obvious using</p>
<pre><code>=IF(REGEXMATCH(B1:C1;"offers");"spring";0)
</code></pre>
<p>but it gives back a <code>#VALUE!</code></p>
<p>In the second step I want to use this formula in a nested if function like here:</p>
<pre><code>=IF(REGEXMATCH(B1;"offers");"spring";IF(REGEXMATCH(B1;"shop");"summer";0))
</code></pre>

74,404,244 | <p>I have a problem
to make migration with relationship.</p>
<p>case :</p>
<ul>
<li>1 Department will have many Employees</li>
<li>1 Employee belongTo 1 Department</li>
<li>1 Department will have one manager (from employees table)</li>
</ul>
<p>Here is my migration</p>
<pre><code>Schema::create('departments', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->foreignId('manager_id')->nullable()
->references('id')->on('employees')
->nullOnDelete();
$table->timestamps();
});
</code></pre>
<hr />
<pre><code>Schema::create('employees', function (Blueprint $table) {
$table->id();
$table->string('name', 255)->nullable();
$table->string('picture', 1024)->nullable();
$table->foreignId('user_id')->nullable()
->references('id')->on('users')
->nullOnDelete();
$table->foreignId('department_id')->nullable()
->references('id')->on('departments')
->nullOnDelete();
$table->timestamps();
});
</code></pre>
<hr />
<p>when I do php artisan migrate:fresh
it show up error :</p>
<pre><code> SQLSTATE[42000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Foreign key
'departments_manager_id_foreign' references invalid table 'employees'.
(SQL: alter table "departments" add constraint "departments_manager_id_foreign" foreign key ("manager_id")
references "employees" ("id") on delete set null)
</code></pre>
<hr />
<p>This because there is no employees table when trying to create departments.
But if I trying to create employees first, then no departments tables.</p>
<p>Any suggestion for my problem ?</p>
<p>Thank you</p>

74,404,261 | <p>I have a list of strings called words such that</p>
<pre><code>words = ['house', 'garden', 'kitchen', 'balloon', 'home', 'park', 'affair', 'kite', 'hello', 'portrait', 'angel', 'surfing']
</code></pre>
<p>I have to find the most occurring letter in every position the strings,
example, let's find the most occurring first letter, so I'll check every first letter of my strings and get 'h' because is the letter that most repeat it self. (If I get two letters that repeat themselves the same amount of times I'll consider the alphabetic order), so the second letter is 'a' because is the letter that repeat itself most time at the second position of all letters, then 'r' because of every third letter in every string is the one that is repeated mostly and so on, at the end I want the string <code>maxOccurs = "hareennt"</code> that is a string that contains all the most frequent letter.
This is what I coded so far:</p>
<pre><code>maxOccurs = ""
listOfChars = []
for i in range(len(words)):
for item in words:
listOfChars.append(item[i])
maxOccurs += max(set(listOfChars), key=listOfChars.count)
listOfChars.clear()
</code></pre>
<p>It raises me and index error out of bound when <code>i == 4</code>, obviously because not every letter has the same length, but I cannot get done with it, I will appreciate any help.
P.S. I can't use any import.</p>

74,404,271 | <p>I have read almost all similar topics but haven't found a working solution for my case.
Sorry for posting similar question again.</p>
<p>Let's imagine I have two strings:</p>
<pre><code>String string1 = "this is my string ";
String string2 = "this is not my string that I want";
</code></pre>
<p>In my case I want my <em>string2</em> to be equal to <em>string1</em></p>
<p>To do so I need to remove <strong>not</strong> and <strong>that I want</strong> parts from <em>string2</em> while collecting these mismatchings.</p>
<p>As a result I would like to have something like this in my code:</p>
<pre><code>List<String> mismatchings = ...; // consists of "not" and "that I want"
String string2Adjusted = "this is my string "; // string2 after adjustment
</code></pre>
<p>Is there any util to do so, Or I might need to do some hard stuff with strings myself?</p>

74,404,354 | <p>My schema in MongoDB looks like this:</p>

<p>I am trying to include the field <code>user.phone</code> only when <code>user.highPrivacy</code> is set to False. Otherwise, I want to exclude the field.</p>
<p>For example, given the above user, I should return the phone number. But if <code>user.highPrivacy</code> was later set to True, it should not include it.</p>
<p>What I have tried so far is this:</p>
<pre><code>dbConnection.aggregate([
{"$match" :
{"_id": userId, "isDeleted" : False}
},
{
"$project" : {
"postings" : 0,
"starredPostings" : 0,

"user.phone" : { "$cond" : [{"$eq": ["$user.highPrivacy", True]}, 0, "$user.phone"] },
}
},

<p>This keep giving me the error:</p>
<pre><code>pymongo.errors.OperationFailure: Invalid $project :: caused by :: Cannot use expression other than $meta in exclusion projection

<p>But the answers that are here:</p>
<ul>
<li><a href="https://stackoverflow.com/questions/37933221/conditionally-include-a-field-id-or-other-in-mongodb-project-aggregation?rq=1">Conditionally include a field (_id or other) in mongodb project aggregation?</a></li>

<p>So where exactly is the issue in my aggregation?</p>

74,404,411 | <p>I want to create a folder and write a file in real external storage (real extern sd card).
I can write to the internal storage, the external storage, but not to the external sd card (I mean the external storage card you put into a cell phone for more space to store images, videos, ...).
The path of the external sd-card is: "/storage/1234-5678/" and it is on a samsung smartphone.
Reading from the external sd card works without problems.
I am testing with Android 8 (and later with higher versions).</p>
<p>I have searched through internet and try but not getting the result, I have added permissions in Android Manifest file as well.</p>
<pre><code><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="29"
tools:ignore="ScopedStorage" />
</code></pre>
<p>and an easy test is:</p>
<pre><code>File directory = new File("/storage/1234-5678/new_folder/");
if (!directory.exists()) {
boolean ok = directory.mkdirs();
}
</code></pre>
<p>The result to ok is always false, when I use the path to the external / removable sd card.<br />
What I am doing wrong?</p>

74,404,422 | <p>Hello I'm trying out CSS transition property, and I'm having some trouble,
when I hover the main tag, the images transitions into their respective positions which I have given, but as soon as I remove the cursor, the images disappear in an instant, without the transition property which I have set,
it works just fine when I'm using only background color instead of image,
I want the transition to be applied also when I remove the hover from the images,</p>
<p>This is the CSS code that I have written</p>

74,404,424 | <p>I'm setting up a new development environment (moved from Windows 7 to Lubuntu), and now I'm trying to set up a React app on it for the first time. Well, second. <code>create-react-app</code> worked, but I like to do things by hand. I finally have <code>webpack</code> and <code>webpack-dev-server</code> working, but when I go to <code>localhost:8080</code>, the React components don't render, and I get three errors relating to an invalid element type.</p>
<p>I read <a href="https://stackoverflow.com/questions/42813342/react-createelement-type-is-invalid-expected-a-string">here</a> that it's usually an import/export problem, but I haven't been able to find it, after following the suggestions given. Here's what I have:</p>
<p>index.js</p>
<pre><code>const React = require('react');
// syntax made no difference
import * as ReactDOMClient from 'react-dom/client'
const App = require('./components/App.js');
const root = ReactDOMClient.createRoot(document.getElementById('app'));
root.render(<App />);
</code></pre>
<p>index.html</p>
<pre><code><!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1.0" />
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<div id="app">This does appear</div>
</body>
</html>
</code></pre>
<p>App.js</p>
<pre><code>const React = require('react');
export default class App extends React.Component {
constructor(props) {
super(props);
console.log("App constructed?");
}
render() {
return (<h1>This should appear</h1>);
}
}
</code></pre>
<p>The three errors:</p>
<blockquote>
<p>Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.</p>
</blockquote>
<blockquote>
<p>Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.</p>
</blockquote>
<blockquote>
<p>Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.</p>
</blockquote>
<p>The only thing on the stack trace that made any sense to me (I can post the rest if you want) comes from the first warning and points to line 7 of index.js, which is <code>root.render(<App />);</code>. I'm not sure how to post my file structure neatly, but I can assure you ./components/App.js (with or without extension) is the correct relative path here.</p>
<p>Any suggestions?</p>
<p>I'm using npm, so I think I have the best versions of each module. Here is my package.json:</p>
<pre><code>{
"name": "try-word",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"dev": "webpack --mode development",
"build": "webpack",
"start": "webpack-dev-server",
"devstart": "webpack-dev-server --mode development"
},
"author": "",
"license": "ISC",
"dependencies": {
"react": "^18.2.0",
"react-dom": "^18.2.0"
},
"devDependencies": {
"@babel/core": "^7.20.2",
"@babel/preset-react": "^7.18.6",
"babel-loader": "^9.1.0",
"html-webpack-plugin": "^5.5.0",
"webpack": "^5.75.0",
"webpack-cli": "^4.10.0",
"webpack-dev-server": "^4.11.1"
}
}
</code></pre>
<p>Anything logged in index.js prints out fine, amidst the errors, but the log in the App constructor never does. It seems like App isn't getting imported correctly, but I'm not sure how to fix that.</p>
<p>EDIT</p>
<p>webpack.config.js</p>
<pre><code>const HTMLWebpackPlugin = require('html-webpack-plugin');
module.exports = {

74,404,427 | <p><strong>EDIT:</strong></p>
<p>Thank you guys for all your input, I'm not sure if the case is resolved but it seems so.</p>
<p>In my former Data preparation function I have shuffled the training sequences, which resulted in LSTM predicting an average.
I was browsing the internet and I have found by accident that other people do not shuffle their data.</p>
<p>I'm not sure if not shuffling the data is ok - it seems strange to me, and I couldn't find the 0-1 answer on this topic, but when I tried, the LSTM infact did well on test dataset:
<a href="https://i.stack.imgur.com/Wkm0H.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Wkm0H.png" alt="enter image description here" /></a></p>
<p>Can someone please elaborate why shuffling the data criplles the model?
Or not shuffling the data in case of LSTM is just as bad as in case of other models?</p>
<p>I am trying to make an LSTM to predict the next value of an indicator but it predicts mean.</p>
<p><strong>Data:</strong>
(Note: Data preparation function is on the bottom of the post so the post itself will be more readable)
I have around <code>25 000</code> entries in each data record and I have <code>14 columns</code> of characteristics.
So my main array is <code>25 000 x 14</code>.
When I prepare my data I am creating sequences in a shape of [number of sequences, samples in a sequence, features] and from then on <code>6 sets</code> of data:</p>
<ol>
<li>X_train, Y_train</li>
<li>X_valid, Y_valid</li>
<li>X_test, Y_test</li>
</ol>
<p>Where Y test is the one step ahead value of a feature I am trying to predict.
Note:
All datasets are scaled with <code>MinMaxScaler</code> in range <code>(-1, 1)</code> hence some data is below zero.</p>
<p>The value I am trying to predicts behaves in a following manner (previous values are inside X datasets):
<a href="https://i.stack.imgur.com/slvoq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/slvoq.png" alt="How data I am trying to predict looks like" /></a></p>
<p><strong>Example of the data sample:</strong>
(Hence, different level of values I've plotted some series on another chart):</p>
<p><a href="https://i.stack.imgur.com/exxVK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/exxVK.png" alt="enter image description here" /></a></p>
<p><strong>The Problem:</strong></p>
<p>The problem is that no matter how many neurons, layers, what activation functions I use it predicts the mean value of a characteristic no matter what, and basically when the neural net hits loss of value around <code>0.078</code> the loss stops decreasing, If I waint longer and give it more epochs on the same <code>learning rate</code> sometimes loss skyrockets to '<code>NaN</code> or <code>10^30</code>.</p>
<p>Here is my Model:</p>
<pre><code>X_train, Y_train, X_valid, Y_valid, X_test, Y_test, scaler = prepare_datasets_lstm_backup(dataset=dataset, samples=200)
optimizer = keras.optimizers.Adam(learning_rate=0.001)
initializer = keras.initializers.he_normal
model = keras.models.Sequential()
model.add(keras.layers.LSTM(64, activation='relu', input_shape=(200, 14), return_sequences=True))
model.add(keras.layers.LSTM(64, activation='relu', return_sequences=True))
model.add(keras.layers.LSTM(3, kernel_regularizer='l2', bias_regularizer='l2', return_sequences=False))
model.add(keras.layers.Activation('sigmoid'))
model.compile(loss='mse', optimizer=optimizer)
history = model.fit(X_train, Y_train, epochs=10, validation_data=(X_valid, Y_valid))
plt.plot(history.history['loss'], label='loss')
plt.plot(history.history['val_loss'], label='val_loss')
plt.legend()
plt.xlabel('Epochs')
plt.ylabel('loss function value')
plt.grid()
plt.show()
prediction = model.predict(X_test)
</code></pre>
<p><strong>The possible solution</strong></p>
<p>While simply increasing number of neurons and layers didn't helped I found a post on <code>CrossValidated</code> stackexchange forum:
<a href="https://stats.stackexchange.com/questions/261704/training-a-neural-network-for-regression-always-predicts-the-mean">https://stats.stackexchange.com/questions/261704/training-a-neural-network-for-regression-always-predicts-the-mean</a>
Where I've read two important things, below I will describe in short words what I've read but you can go and check out these answers:</p>
<ol>
<li>go to the @mhdadk's answer and check it out.</li>
<li>got to the Bob's answer and check it out.</li>
</ol>
<p>So the conculsion is that maybe my Neural Network is not complex enough even with <code>1000 neurons</code> in <code>two layers</code>. It would certainly be interesting to chekc out the neural net with <code>10000 neurons</code> and see if it works, but the problem is I would have to run it on Google Cloud VM, where it would propably compute for a month hence I have a limit of 8 CPU's per VM.</p>
<p><strong>The first Question:</strong></p>
<p>Is it even worth trying to build a neural net with 10k-50k neurons, since I have no idea if it would bring some positive results, and if not I would wast 500 USD or 1000 USD or even more and a month or more of time.
What do you think?</p>
<p><strong>Second Question</strong></p>
<p>If predicting the raw value seems undoable, then could the neural network actually work with classification i.e. predicting if the next value will be between certain treshold, above it or beneath it? Or would it predict mean value of class also i.e. most frequent class for all predictions?</p>
<p><strong>Third question</strong></p>
<p>Can it be the case that I am feeding a neural net with too much data and limitng the data to 5 000 or 10 000 entries would help?</p>
<p><strong>Fourth question</strong></p>
<p>Do you have any other ideas that might help with the prediction?</p>
<p>Thank you all for your time reading this and thank you for your help in advance :)</p>
<p>As I wrote above here is the data preparation function:</p>
<pre><code>def prepare_datasets_lstm(dataset : pd.DataFrame, samples : int):

74,404,433 | <p>I am VERY new to rust, and really programming in general. I am writing a rust program that will detect idle and print out the time since the last input. I am using the winapi crate. The code below returns between 0ns and 31ms, regardless of how long it's been since I pressed a key or moved the mouse. It never gets higher than 31ms.</p>
<pre><code>use winapi::um::{
winuser::{
LASTINPUTINFO,
PLASTINPUTINFO,
GetLastInputInfo
},
};
fn sleep(milliseconds: u64){
let mills = std::time::Duration::from_millis(milliseconds);
std::thread::sleep(mills);
}
fn main() {
loop {
let now = unsafe { winapi::um::sysinfoapi::GetTickCount() };
let mut last_input_info = LASTINPUTINFO {
cbSize: std::mem::size_of::<LASTINPUTINFO>() as u32,
dwTime: 0
};
let p_last_input_info: PLASTINPUTINFO = &mut last_input_info as *mut LASTINPUTINFO;
let ok = unsafe { GetLastInputInfo(p_last_input_info) } != 0;
let logvar = match ok {
true => {
let millis = now - last_input_info.dwTime;
Ok(std::time::Duration::from_millis(millis as u64))
},
false => Err(format!("GetLastInputInfo failed"))
}.unwrap();
println!("{:?}", logvar);
sleep(1000);
};
}
</code></pre>
<p>I considered that it might be some program that is keeping the PC from going idle, so using powercfg -requests, I found some audio streams open (still don't know how to fix that). I just don't know if that could be what's happening here. Community expertise requested!</p>

74,404,471 | <p>So, I don't know how can I print elements of such a list.</p>
<pre><code>list<int>* a;
a = new list<int>(4);
a[0].push_back(1);
a[0].push_back(3);
a[2].push_back(5);
a[2].push_back(7);
cout << a[0].front() << '\n';
cout << a[1].back() << '\n';
</code></pre>
<p>Firstly, I tried to print it via range-based for loop, but it didn't work either.</p>
<pre><code>for(auto element: a[0]) cout << element << '\n'; // doesn't work

<p>REQUEST (CLIENT)</p>
<pre><code> try{
const response = await axios.post("https://myUrl.com/users/login", user);

74,404,527 | <p>I'm trying to make a crossword in google sheets, and would like the clue numbers to be as far up in the top left of the cell as possible. Using the normal alignment buttons puts in in the corner, but still further away from the cell edge than I like. Is there way to specify the margins within a cell between text and the borders?</p>
<p>Thanks!</p>

74,404,561 | <p>I have two tables, <code>table_A</code> and <code>table_B</code>. I want to do a left join on both tables so that each record in table_A is matched with a record in table_B using the date as a key. However some dates in A will be missing in B and vice-versa. So my goal is to join A and B using the closest earlier date in B.</p>
<p>There is one other condition I need to join on. So take the following code for example:</p>
<pre><code> SELECT a.*, b.*
FROM table_A a
LEFT JOIN table_B b ON a.product = b.product AND a.date = b.date
</code></pre>
<p>If the dates were exactly the same, I could use the above code. However they're not, so I want the closest lesser date in table_B to use a match for table_A.</p>
<p>Based on some solutions I saw, I tried the following:</p>
<pre><code> SELECT a.*, b.*
FROM table_A a
LEFT JOIN table_B b ON a.product = b.product
AND a.date = (SELECT MAX(date) FROM table_B WHERE date <= a.date)
</code></pre>
<p>I thought this would work becuase I am searching for the max date in table_B that is still less than the date in table_A, however I returning nulls for the fields in table_B.</p>
<p>Perhaps it has to do with the other condition which is <code>a.product = b.product</code>?</p>

<pre class="lang-sql prettyprint-override"><code>drop database if exists hoteltest;

insert into Roomreservation
values

74,404,613 | <p>I'm new to React 18 and Suspense. Nearly all of my previous web development was done in asp.net mvc. I want to click a button on a form, pass the form input values to a web api HttpGet method with the [FromQuery] attribute, and render the return into a div.</p>
<p>If I were doing this in asp.net mvc, I would wire up a button click event like so in javascript:</p>
<pre><code>const btnSearch = document.getElementById('btnSearch');
btnSearch.addEventListener("click", function() {
executeMySearch();
return false;
});
</code></pre>
<p>And in the executeMySearch() method I'd grab the form input values, send them to server, fetch some html from the server and plunk it into a div like so:</p>
<pre><code>const searchresults = document.getElementById('searchresults');
let formData = new FormData(document.forms[0]);
fetch('/Index?handler=MySearchMethod', {
method: 'post',
body: new URLSearchParams(formData),
}).then(function (response) {
return response.text();
}).then(function (html) {
searchresults.innerHTML = html;
</code></pre>
<p>Of course in React the approach is completely different, I showed the code above only to demonstrate what I want to happen. I want the search to execute only when the search button is clicked. My problem is, I cannot figure out how to manage React state to make that happen. Currently, after the search button is clicked once, my search is executing every time the user changes the value of a form input. I understand why that is happening, but I can't figure out how to structure my components so that the search executes only when the search button is clicked.</p>
<p>Server-side, my web api receives a form and returns a generic list, like so. This works fine:</p>
<pre><code>[HttpGet("MySearchMethod")]
public async Task<List<MySearchResult>> MySearchMethod([FromQuery]MySearchForm mySearchForm)
{
return await _myRepository.GetMySearchResults(mySearchForm);
}
</code></pre>
<p>In my React app I have a search component. The component renders a form with the following elements:</p>
<ul>
<li>four selects, which contain the search criteria. These selects are wrapped in React components.</li>
<li>a search button</li>
<li>a component that renders the search results</li>
</ul>
<p>Each select input is a React component that contains a list of enums fetched from the web api. Each select is defined in the search component like so:</p>
<pre><code>const MyEnums = lazy(() => import('./MyEnums'));
</code></pre>
<p>Each of these React components is tied to the React state when the search component is defined, like so:</p>
<pre><code>const MySearchComponent = () => {
const [myEnum, setMyEnum] = useState(0);
function onChangeMyEnum(myEnumId : number){
setMyEnum(myEnumId);
}...
</code></pre>
<p>and I tie my search button to React state like so:</p>
<pre><code>const [isSearch, setIsSearch] = useState(false);
</code></pre>
<p>My search component returns a form with the search criteria and search button, and a div to contain the search results:</p>
<pre><code> return (
<>
<form>
<div>
<ErrorBoundary FallbackComponent={MyErrorHandler}>
<h2>My Search Criteria Select</h2>
<Suspense fallback={<Spinner/>}>
<MyEnums onChange={onChangeMyEnum} />
</Suspense>
</ErrorBoundary>
</div>
<button className='btn btn-blue' onClick={(e) => {
e.preventDefault();
setIsSearch(true);
}
}>Search</button>
</form>
<div>
{
isSearch === true ?
<ErrorBoundary FallbackComponent={MyErrorHandler}>
<Suspense fallback={<Spinner/>}>
<MySearchResults myEnum={myEnum} [..other search criteria] />
</Suspense>
</ErrorBoundary>
: <span>&nbsp;</span>
}
</div>
</code></pre>
<p>Everything works fine. The problem is, after the first time the search button is clicked (which executes "setIsSearch(true)"), every time a user alters a selection in one of the form inputs, the search executes. I understand why. My "isSearch" variable remains true, so when the state is altered by the form input changing, and the component is re-rendered, the search happens again.</p>
<p>I tried passing the "setIsSearch" method into the MySearchResults component, and calling setIsSearch(false) after the component rendered, but that of course does exactly what it is supposed to to. The React state changes, the component re-renders, it sees that "isSearch" is false, and it makes the search results disappear. When I click my search button I see the search results flicker briefly and then disappear, which is exactly what should happen.</p>
<p>I also tried calling setIsSearch(false) every time a select changes, but of course this causes my search results to disappear, which is not desired.</p>
<p>What am I missing? How do I structure this so that the search only occurs when I click the Search button?</p>
<p>P.S. the web api call is made inside of the MySearchResults component when it renders. The MySearchResults component looks like this:</p>
<pre><code>import React from 'react';
import { useQuery } from 'react-query';
import MySearchResult from './MySearchResult';
const fetchMySearchResults = async (myEnumId : number [...other criteria]) => {
let url = `${process.env.REACT_APP_MY_API}/GetMySearchResults/?myEnumId=${myEnumId}&[...other criterial]`;
const response = await fetch(url);
return response.json();
}
const MySearchResults = (props : any) => {
const {data} = useQuery(['myquery', props.myEnum,...other search criteria...]
,() => fetchMySearchResults(props.myEnun [...other search criteria]),
{
suspense:true
});
return (
<>
<table>
<thead>
<tr>
<th>My Column Header</th>
<th>...and so on</th>
</tr>
</thead>
<tbody>
{data.map((mySearchResult: {
...and so on
</tbody>
</table>
</>
);
};
export default MySearchResults;

74,404,619 | <p>I have a very large database that looks like this. For cntext, the <code>data</code> appartains to different companies with their related CEOs (<code>ID</code>) and the different years each CEO was in charge</p>
<pre><code>ID <- c(1,1,1,1,1,1,3,3,3,5,5,4,4,4,4,4,4,4)
C <- c('a','a','a','a','a','a','b','b','b','b','b','c','c','c','c','c','c','c')

data <- c(30,50,22,3,6,11,5,3,7,6,9,31,5,6,7,44,33,2)
df1 <- data.frame(ID,C,fyear, data)

<p>I need to build a code that allows me to sum up the previous 5 and 3 <code>data</code> related to each <code>ID</code> for every year. So t-3 and t-5 for each year. The result is something like this.</p>
<pre><code>ID C fyear data data3data5
1 a 2000 30 NA NA
1 a 2001 50 NA NA
1 a 2002 22 102 NA

4 c 2004 44 57 93
4 c 2005 33 84 95
4 c 2006 2 79 92
</code></pre>
<p>I have different columns of data for which I need to perform this operation, so if somebody also knows how I can do that and create a <code>data3</code> and <code>data5</code> column also for the other columns of data that I have that would be amazing. But even just being able to do the summation that I need is great! Thanks a lot.
I hav looked around but don't seem to find any similar cses that satisfy my need</p>

74,404,627 | <p>I have Invoices with many Invoice Line Items. Invoice line items point to a specific item. When creating or updating an Invoice, I'd like to validate that there is not more than 1 invoice line item with the same Item (Item ID). I am using accepts nested attributes and nested forms.</p>
<p>I know about <code>validates_uniqueness_of item_id: {scope: invoice_id}</code></p>
<p>However, I cannot for the life of me get it to work properly. Here is my code:</p>
<p><strong>Invoice Line Item</strong></p>
<pre><code>belongs_to :item
validates_uniqueness_of :item_id, scope: :invoice_id
</code></pre>
<p><strong>Invoice</strong></p>
<pre><code>has_many :invoice_line_items, dependent: :destroy
accepts_nested_attributes_for :invoice_line_items, allow_destroy: true
</code></pre>
<p><strong>Invoice Controller</strong></p>
<pre><code> // strong params
params.require(:invoice).permit(
:id,
:description,
:company_id,
invoice_line_items_attributes: [
:id,
:invoice_id,
:item_id,
:quantity,
:_destroy
]
)
// ...
// create action
def create
@invoice = Invoice.new(invoice_params)
respond_to do |format|
if @invoice.save
format.html { redirect_to @invoice }
else
format.html { render action: 'new' }
end
end
end
</code></pre>
<p>The controller code is pretty standard (what rails scaffold creates).</p>
<p><strong>UPDATE</strong> - NOTE that after more diagnosing, I find that on create it always lets me create multiple line items with the same item when first creating an invoice and when editing an invoice without modifying the line items, but NOT when editing an invoice and trying to add another line item with the same item or modifying an attribute of one of the line items. It seems to be something I'm not understanding with how rails handles nested validations.</p>
<p><strong>UPDATE 2</strong> If I add <code>validates_associated :invoice_line_items</code>, it <em>only</em> resolves the problem when editing an already created invoice without modifying attributes. It seems to force validation check regardless of what was modified. It presents an issues when using _destroy, however.</p>
<p><strong>UPDATE 3</strong> Added controller code.</p>
<p><strong>Question</strong> - how can I validate an attribute on a models has many records using nested form and accepts nested attributes?</p>
