I am trying to make a card animation where a card on the top of the deck would translate upwards when hovered. Unfortunately, it seems like my card flickers if I move my mouse horizontally over the bottom part of the card. I have made some tests and it seems to be related to the translate, as increasing the translate on hover will result in having a greater area accross the flickering happens. Sorry if I explained this bad, hopefully looking at the code will show what my issue is( simply mouse over the translated area after the translate has taken place and move your mouse vertically. You can also increase the translate to see the results).
I would be looking for any suggestions regarding this and/ or any advice regarding my code.
Thank you for your time and effort!

I tried increasing modifying the translate and position properties, as well as the top and transitions, however it doesn't make much of a difference. |

I am a grad student getting my MBA with an emphasis in finance. I am struggling to answers this question as I have no experience in coding. I am supposed to work the problem using python. Any help would be greatly appreciated!
**PROBLEM**
Problem Statement: We have a project with given cashflows.
[-50, 20, 10, 30, 10, 15]
The first element is negative and represents the initial investment required for the project. The subsequent elements represent the expected cash inflows and outflows from the project over 15 periods.
We would like to calculate the Internal Rate of Return (IRR) of this project. As a reminder, the IRR is the discount rate at which the NPV of a project equals zero. Therefore, we are looking for an
such that
()=0⇒−50+201++10(1+)2+30(1+)3+10(1+)4+15(1+)5=0.
In this exercise, we will numerically solve this equation using Numpy. The idea is to calculate ()
over a grid of
, e.g., [0,0.001,0.002,0.003,…,0.199,0.200]
, and find a point on the grid where ()
is close to zero. The finer our initial grid, the closer we can get to the root of the equation above.
Your task is to:
Define the cash flows array.
Create an array of potential discount rates ranging from 0% to 20%.
Calculate the NPV for each discount rate.
Identify the discount rate at which the NPV is closest to zero. This rate is the project's approximate IRR.
**GUIDE**
Step 1:
import numpy as np
# Define the number of points on the grid
N = 10001
# Define cashflows
cash_flows = np.array([-60, 20, 10, 30, 10, 15])
# Define the array of potential discount rates
r = np.linspace(0, 0.20, N)
# Define an array to keep NPV values
npv = np.zeros((N,))
Step 2:
# Calculate NPVs for each value of the discount rate
for i in range(N):
# Calculate NPV for discount rate = r[i]
Step 3:
# Identify the discount rate at which NPV is closest to zero
index = np.argmin(np.abs(npv))
Step 4:
# Print the IRR
Step 5:
# Copy the code for N = 1001
Step 6:
# Copy the code for N = 10001

I am trying to build my object using the below Json payload(which is being fetched from external API), now when ever i use any get method(i.e: jsonObject.getString() or jsonObject.getBoolean(), jsonObject.getObject()) and
if the value present for the key is null,I am getting an exception that "the value is not a string/boolean/Jsonobject"
now how can i handle this, since if the value is present in object 1 on the above array index 0, it may/maynot present in another object at index 1
here I an apply null checks to resolve this issue, but this object has more than 40 key value pairs and add these many null checks may become cumbersome

If you create a `table` of `dice.sums`, then you will get the frequency of each possible sum. Dividing this table by its total will give you the probability of each sum. The rest is just data wrangling to get it into the correct format, for which `dplyr` will be useful:
``` r
library(dplyr)
table(dice.sums) %>%
as.data.frame() %>%
mutate(dice.sums = as.numeric(as.character(dice.sums)),
prob = Freq/sum(Freq),
floor = 10 * floor(dice.sums/10)) %>%
summarise(range = paste(min(dice.sums), max(dice.sums), sep = ' - '),
prob = round(sum(prob), 8), .by = floor) %>%
select(range, prob)
#> range prob
#> 1 10 - 19 0.00148046
#> 2 20 - 29 0.15502340
#> 3 30 - 39 0.63852791
#> 4 40 - 49 0.20207825

In my project I am trying to use `net.sf.saxon.s9api.XsltTransformer` in multiple threads using synchronization in java because as per documentation An XsltTransformer must not be used concurrently in multiple threads. It is safe, however, to reuse the object within a single thread to run the same stylesheet several times. Running the stylesheet does not change the context that has been established. Some of the public methods are synchronized: this is not because multi-threaded execution is supported, rather it is to reduce the damage if multi-threaded execution is attempted. but while trying to make stress test using JMeter by sending 100 request per second I found that `net.sf.saxon.s9api.XsltTransformer.transform()` takes more time and sometimes reach to 6 mins.
How can I use `net.sf.saxon.s9api.XsltTransformer.transform()` in multiple threads without impacting performance?
I tried to make class TransformerSingleton as below
```
public class TransformerSingleton {
private static XsltTransformer transformer;
private TransformerSingleton() {
}
public static void xsltLoad() {
if (transformer == null) {
synchronized (XsltTransformer.class){
try {
Processor processor = new Processor(false);
XsltCompiler compiler = processor.newXsltCompiler();
XsltExecutable xslt = compiler.compile(new StreamSource("/my_path/"));
transformer = xslt.load();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
public static XsltTransformer getTransformer(){
if (transformer == null) {
synchronized (XsltTransformer.class) {
xsltLoad();
}
} return transformer;
}
}
```
```
public static void main(String[] args) {
XsltTransformer transformer = XsltTransformerSingleton.getTransformer();
String xml = "<Users><name>AAA</name></Users>"; // for example
try (ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(xml.getBytes())) {
synchronized (transformer){
Transformer.setSource(new StreamSource(byteArrayInputStream));
XdmDestination chainResult = new XdmDestination();
Transformer.setDestination(chainResult);
Transformer.transform();
}
}
}
```
expected to make throughput reach to 100 requests per second.
actual I reached to 60 per second. |
You are getting a blank window because you didn't call a `pack()`, `grid()` or `place()` method on the self.menu widget.
To fix this you can add `self.menu.pack()` on line 13. The full code is the following:
```python
from customtkinter import *
class app(CTk):
def __init__(self, title, size):
# main setup
super().__init__()
self.title(title)
self.geometry(f'{size[0]}x{size[1]}')
self.minsize(size[0], size[1])
# widget
self.menu = CTkFrame(self)
self.menu.pack()
# run
self.mainloop()
class Menu(CTkFrame):
def __init__(self, parent):
super().__init__(parent)
self.place(x=0, y=0, relwidth=0.3, relheight=1)
self.create_widgets()
def create_widgets(self):
heading_var = StringVar(value="Ethan")
def heading_combo(choice):
print(choice)
heading = CTkComboBox(self, values=["Ethan", "Brock", "Liam"], command=heading_combo, variable=heading_var)
self.columnconfigure((0, 1, 2), weight=1, uniform='a')
self.rowconfigure((0, 1, 2, 3, 4), weight=1, uniform='a')
heading.pack()
app('Scoring Software', (600, 600))
```
But your code seems weird, you are creating a Menu class but not using it.
If you thought doing this `class Menu(CTkFrame):` would completly overwrite the CTkFrame class, you are wrong, it just creates a new class with modified methods.
To use the Menu class you created, you should replace the 12th line by this:
```python
self.menu = self.Menu(self)
```
Hope I helped you, have a nice day |

For example, let's say there's 100 rows in task_dispersal (therefore 100 order_ids). For each of those 100 order_ids, the query will chose a random user_id in the user_table, filtering out user_id's that have already been inserted into the task_pool for that order_id.
The query above works great, but slows down as the amount of rows in users and task_pool increase (expected of course, I'd just hope to minimize the delay).
Let's say I have 985187 rows in task_pool (so 985187 task_ids), 49156 rows in user table (49156 user_ids), and 100 rows in task_dispersal (100 order_ids).
The query now takes ~9.5 seconds to complete.

I am experiencing a problem with displaying button icons in the QDialog window. This problem occurs when trying to run the window from the main file, knowing that the QDialog window file is not in the same path as the main file.
This is the code to import the design from the `__init__.py` file inside WindowAdd
```
from PySide6.QtUiTools import QUiLoader
from PySide6.QtCore import QFile, QDate, Qt, QRect, QPropertyAnimation, QEasingCurve ,QTimer
from PySide6.QtWidgets import QApplication, QWidget, QTableWidgetItem, QPushButton, QDialog, QListWidgetItem, QCompleter
from PySide6 import QtGui, QtWidgets, QtCore
from .ui_Add_Item import Ui_Form
from Lib import database3
from datetime import datetime
from functools import partial
import random
import time
import os
import sys
class CustomListWidgetItem(QListWidgetItem):
def __init__(self, text, hidden_data):
super().__init__(text)
self.hidden_data = hidden_data
class Widgets(QDialog, Ui_Form):
def __init__(self, parent=None, page=""):
super(Widgets, self).__init__(parent)
self.setupUi(self)
if __name__ == "__main__":
app = QApplication([])
window = Widgets()
window.show()
app.exec()
```
I tried to execute a local code inside WindowAdd and the icons appeared very normally without the slightest problem, but when I exit to the main file the problem returns again.
These are the libraries and the most important codes used inside the `main.py`
```
from PySide6.QtUiTools import QUiLoader
from PySide6.QtCore import QFile, Qt
from PySide6.QtWidgets import QApplication, QWidget, QTableWidgetItem, QMenu, QGraphicsBlurEffect
from PySide6 import QtGui, QtWidgets, QtCore
from PySide6.QtGui import QBrush, QColor, QAction, QTextOption, QIcon
from ui_Style3 import Ui_Form
from WindowAdd import Widgets as WindowAdd2
from Lib import database3
from datetime import datetime
import random
import sys
class Widgets(QWidget,Ui_Form):
def __init__(self):
super(Widgets, self).__init__()
self.setupUi(self)
#Title window name and icon
self.setWindowTitle("Business record") #Name title
self.setWindowIcon(QtGui.QIcon("path30.png")) #Icon title
if __name__ == "__main__":
app = QApplication(sys.argv)
window = Widgets()
window.show()
sys.exit(app.exec())
```
Just for your information, I use the design files from the Qt Designer program to download the ready-made design files. The `main.py` file and the `__init__.py` file are files to control the design files and execute instructions. |

I am using the following snippet for preprocessing:
```
# Data augmentation
train_datagen = tf.keras.preprocessing.image.ImageDataGenerator(
rotation_range=10,
width_shift_range=0.1,
height_shift_range=0.1,
shear_range=0.1,
fill_mode='constant',
cval = 0)
```
Additionally, I am using GPU P100 on Kaggle. I was having some errors when I would run the `model.fit` method. So I was debugging.
Only untill I went through the Keras doc, I knew that the Module: tf.keras.preprocessing is deprecated. Or at least this is what I understood from this doc [link.](https://www.tensorflow.org/api_docs/python/tf/keras/preprocessing)
Also, hovering over the preprocessing header that encloses the overview, a small pop-up reads **Deprecated**.
[](https://i.stack.imgur.com/UIpXa.jpg)
I wanted to know what is the alternative now? |

The instructions you found were actually broken (missing details) and not recommended (wfastcgi was deprecated).
If you revert all changes related to FastCGI and start cleanly with HttpPlatformHandler, you will see how smooth the experience is,
``` xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" requireAccess="Script" />
</handlers>
<httpPlatform stdoutLogEnabled="true" stdoutLogFile=".\python.log" startupTimeLimit="20" processPath="C:\Users\<user name>\AppData\Local\Programs\Python\Python310\python.exe" arguments=".\mysite\manage.py runserver %HTTP_PLATFORM_PORT%">
</httpPlatform>
</system.webServer>
</configuration>
```
Python/Django still takes care of everything including static files, and IIS/HttpPlatformHandler just passes requests on.
More details can be found from [my blog post](https://docs.lextudio.com/blog/running-django-web-apps-on-iis-with-httpplatformhandler/). |
i found you need to do something like this is powershell core 7
```
terraform state rm 'resource[\"thing\"]'
```
this is doc'd with an example over at https://developer.hashicorp.com/terraform/cli/commands/state/show#example-show-a-resource-configured-with-for_each
Update 2023-01, dunno what's changed but in PS7 latest and TF latest i haven't needed the \ anymore despite the docs saying i do, this seems to work now
```

I have scaled my dataset using the standard scaler form sklearn like this:
from sklearn.preprocessing import StandardScaler
...
# create a StandardScaler object
self.scaler = StandardScaler()
# fit the scaler to the dataset
self.scaler.fit(self.X_org)
# transform dataset using the scaler
self.X_scalled = pd.DataFrame(self.scaler.transform(self.X_org), columns=self.X_org.columns)
return self.X_scalled
However, I am now using the last 10% of the entire dataset for a validation run also scaling the data with the scaler from the training dataset like so:
X_input_val_data_scalled = pd.DataFrame(self.scaler.transform(X_input_val_data), columns=X_input_tick_data.columns)
Now my challenge:
In the training X_org set I get a nicely scaled dataset from 3 to -3. In the scaled validation X dataset I get completely wired data ranging from 50 to -75...
What am I doing wrong? |
Calling Standard Scaler differes between same sets |

I'm trying to setup a report that has line item details summarized by a subgroup for each. On each line, I want to add a checkbox, with the subtotal of each group being a "master" checkbox that would change all of the corresponding checkboxes if it's clicked.
My solution is to create an individual click event for each master checkbox that updates everything with a similar name (i.e. line items have checkbox names File1_1, File1_2, and subtotal line has name Master_File1). To create each report, I run the data through a processor spreadsheet, so each of these click events needs to be added through VBA.
When I try to apply the event procedure, I get an "Event handler is invalid" error on the `.CreateEventProc` line. The first snippet below is the subprocedure to apply the macro (the proc_lines code has been tested and works how I want it to, just can't get it implemented). I originally received an error for trying to pass the worksheet name I gave it ("Ops Staff 1"), so I changed the sheet name to be the VBA type ("Sheet3")
Private Sub add_master_checkbox_module(sheet_name As String, report_book As Workbook, checkbox_name as String)
Dim VB_proj As Object
Dim VB_comp As Object
Dim code_mod As Object
Dim line_number As Long
Dim proc_lines As String
On Error GoTo Error_ClickEvent
Set VB_proj = report_book.VBProject
Set VB_comp = VB_proj.VBComponents(sheet_name)
Set code_mod = VB_comp.CodeModule
proc_lines = "Dim cbx As CheckBox" & vbLf & _
"Dim val As Long " & vbLf & _
"Dim grp As String " & vbLf & _
vbLf & _
vbTab & "grp = Application.Caller " & vbLf & _
vbTab & "val = ActiveSheet.CheckBoxes(grp).Value" & vbLf & _
vbTab & "grp = Split(grp, ""_"")(1)" & vbLf & _
vbLf & _
vbTab & "For Each cbx In ActiveSheet.CheckBoxes" & vbLf & _
vbTab & vbTab & "If cbx.Name Like grp & ""_*"" Then" & vbLf & _
vbTab & vbTab & vbTab & "cbx.Value = val" & vbLf & _
vbTab & vbTab & "End If" & vbLf & _
vbTab & "Next cbx"
With code_mod
Debug.Print checkbox_name
line_number = .CreateEventProc("Click", checkbox_name)
line_number = line_number + 2
.InsertLines line_number, proc_lines
End With
Error_ClickEvent:
MsgBox Err & ": " & Err.Description
End Sub
Below is the part of the main procedure where the checkbox is created and the above is called. `rg` refers to a range in a for loop.
With temp_sheet.CheckBoxes.Add(Left:=rg.Left + (rg.Width / 2#) - 12, Top:=rg.Top, Width:=12, Height:=rg.Height)
.Caption = ""
.LinkedCell = rg
.Name = checkbox_name
End With

I keep getting undefined when I try to destructure the body object from my `const { title, body, userId } = request.body;`
I have 2 components, a server that post data to an API endpoint and a client component that reads the server component locally and is supposed to send the body data collected from inputs to the server content. am not getting any error aside from undefined. here is the server component:
```
import { NextResponse } from "next/server"
export async function GET() {
const res = await fetch('https://jsonplaceholder.typicode.com/posts')
const data = await res.json()
// console.log({ data })
const post = data.slice(0,5)
return Response.json({ data:post })
}
export async function POST(request, response) {
const { title, body, userId } = request.body;
console.log({ title, body, userId })
const fetchResponse = await fetch('https://jsonplaceholder.typicode.com/posts', {

body: JSON.stringify({
title,
body,
userId,
})
});
const data = await fetchResponse.json();
console.log(data)
return NextResponse.json(data);
}
```
and here is the client component:
```

My Firebase Realtime Database saves each user with 4 features: name, email, password, and confirm password.
The class of users:
public class Users
{
String Username,Email,Password,ConfirmPassword;
public Users() {
}
public Users(String username, String email, String password, String confirmPassword) {
Username = username;
Email = email;
Password = password;
ConfirmPassword = confirmPassword;
}
public String getUsername() {
return Username;
}
public void setUsername(String username) {
Username = username;
}
public String getEmail() {
return Email;
}
public void setEmail(String email) {
Email = email;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
public String getConfirmPassword() {
return ConfirmPassword;
}
public void setConformPassword(String conformPassword) {
ConfirmPassword = conformPassword;
}
}
The Firebase data that i saved:
{
"user": {
"user22": {
"confirmPassword": "12345678",
"email": "user22@gmail.com",
"password": "12345678",
"username": "user22"
}
}
}
In my app I have the option to change the current password to a new password, it requires you to put in your previous password(the current one that the Firebase saved) and then put new password(the user puts the data about the passwords on UI 'EditText').
See here how it looks:
[enter image description here](https://i.stack.imgur.com/xvLcQ.png)
Then the user has to click on 'confirm button' to change the old password to a new one. But before its changes,***the computer need to check if the old password compares to the current password that is saved on Firebase*** . I don't know how to do that, please help me!!
I tried to do that code but not sure if I get the access to the variable that I want:
public void showUserName()
{
FirebaseDatabase Data= FirebaseDatabase.getInstance();
DatabaseReference myRef=Data.getReference("user");
myRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
username.setText(snapshot.child("username").getValue(String.class));
}
@Override
public void onCancelled(@NonNull DatabaseError error) {
}
});
}
It always changed even when the previous pass don't compare to the current..

Is it possible to write a Chrome/Firefox plug-in that can automatically open the dev tools for every open tab and execute code in the console?
I have already done this with Selenium, but I would like to have it as a plug-in.
Unfortunately, I haven't found a chrome api yet that allows you to automatically insert and execute code in devtools.
I would be very grateful to anyone who could help me get a step closer. |

Let's assume you have those 2 files :
layout.html
```
...imagine a plain HTML file, with the body having an id attribute set to "body"
Somehow I cannot get to get this piece of code inside the SO editor it just won't show...
```
content.htm
```
<h1>DOM content</h1>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
```
Here is the code for index.php that will insert content.htm in layout.html
```
loadHTMLFile('layout.html');
// loads the content of the document
$content = new DOMDocument();
$content->loadHTMLFile('content.htm');
// imports a copy of the content into the main document
$import = $layout->importNode($content->getElementById('content'), true);
$body = $layout->getElementById("body");
$body->appendChild($import);
echo $layout->saveHTML();
```
A few thoughts and notes :
- even if you only load a partial html document, DOMDocument::loadHTMLFile will create a complete HTML document and insert your file inside.
- for instance, this is what's inside the $content object :
```
<h1>DOM content</h1>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
```
- you cannot move nodes from one document to another, you need to import those
- once imported, the nodes will not show as they are not attached to any other nodes in the document : you have to do it manually (appendChild here). |
You should first check loki api `GET ~/loki/api/v1/rules` give the correct response.

I'm attempting to retrieve user data, but the method is returning an empty object.
bot.py
```
menuId = "id"
webapp = "https://localhost" + "/" + menuId
bot = telebot.TeleBot(API_TOKEN)
def webAppKeyboardInline():
keyboard = types.InlineKeyboardMarkup(row_width=1)
webApp = types.WebAppInfo(webapp)
one = types.InlineKeyboardButton(text="Open", web_app=webApp)
keyboard.add(one)
return keyboard
@bot.message_handler(commands=['start'])
def handle_start(message):
bot.send_message(message.chat.id, "hello!", reply_markup=webAppKeyboardInline())
bot.infinity_polling()
```
There is nothing interesting on the website, I simply get an object. But, despite the button type, it is always an empty object.
I've experimented with various button techniques.

I am trying to build my object using the below Json payload(which is being fetched from external API), now when ever i use any get method(i.e: jsonObject.getString() or jsonObject.getBoolean(), jsonObject.getObject()) and
if the value present for the key is null,I am getting an exception that "the value is not a string/boolean/Jsonobject"
now how can i handle this, since if the value is present in object 1 on the above array index 0, it may/maynot present in another object at index 1
here I can apply null checks to resolve this issue, but this object has more than 40 key value pairs and add these many null checks may become cumbersome, is there any better way to resolve this?

I discovered that the approach with `ForEach-Object` works (although I don't understand why), while the approach without `ForEach-Object` does not.
$obj = [pscustomobject]@{id=4444}
# doesn't work
$obj | get-process -id $_.id
# it works
$obj | foreach{get-process -id $_.id}
Apparently the "foreach" does the trick, but why?

This may be old, but I'm just doing some support on such an old system:
instead of:
public EntitiesContext()
: base("name=EntitiesContext")
just use
public EntitiesContext()
: base("EntitiesContext")
and you should be good to go. |
I'm having trouble building v8 and libv8 to use with v8js php library. I'm running `gm x64.release` on the depot_tools git repo after running `fetch v8; cd v8` and the v8 file and g8 file gets created but the problem is that i cannot find the libv8/libnode required to compile v8js using pecl (https://github.com/phpv8/v8js). Here is the tree of the build output: https://pastebin.com/WAfxFegy
I tried installing libv8-dev (on Ubuntu 22 it automatically replaces it with libnode-dev) but still nothing.
How can i solve this? Thanks a lot!
P.S: This is the output i get once i run the pecl install:
```shell
sudo pecl install v8js

**TL;DR**
```python
pl_series = [pl.Series(name, values)
for name, values in zip(features, shuffle_arr.T)]
X_train_permuted = (
X_train_permuted.with_columns(
pl_series
)
)
```
-----
Let's work with a simple example.
**X_train_permuted**
```python
import polars as pl
import numpy as np
np.random.seed(0)
data = {f'feature_{i}': np.random.rand(4) for i in range(0,3)}
X_train_permuted = pl.DataFrame(data)
X_train_permuted
shape: (4, 3)
┌───────────┬───────────┬───────────┐

└───────────┴───────────┴───────────┘
```
**Shuffle `feature_1` and `feature_2`**
Use a list to keep track of the features you are shuffling: `features = ["feature_0", "feature_1"]`.
```python
features = ["feature_0", "feature_1"]
shuffle_arr = np.array(X_train_permuted[:, features])
from sklearn.utils import check_random_state
random_state = check_random_state(42)
random_seed = random_state.randint(np.iinfo(np.int32).max + 1)
random_state.shuffle(shuffle_arr)
shuffle_arr
array([[0.71518937, 0.64589411],
[0.60276338, 0.43758721],
[0.5488135 , 0.4236548 ],
[0.54488318, 0.891773 ]])
```
**Replace associated columns in `X_train_permuted` with `shuffle_arr` values**
* Use [`pl.DataFrame.with_columns`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.with_columns.html).
* Pass a list (here: `pl_series`) with a [`pl.Series`](https://docs.pola.rs/py-polars/html/reference/series/index.html) for each shuffled feature, using a list comprehension (applying [`zip`](https://docs.python.org/3.3/library/functions.html#zip)). Make sure to transpose `shuffle_arr` to access to columns (see [`.T`](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.T.html#numpy.ndarray.T)).
```python
pl_series = [pl.Series(name, values)
for name, values in zip(features, shuffle_arr.T)]
X_train_permuted = (
X_train_permuted.with_columns(
pl_series
)
)
X_train_permuted

**Alternative (unstable!)**
You could also use [`pl.DataFrame.update`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.update.html). Note, however, the warning in the docs:
> This functionality is considered **unstable**. It may be changed at any point without it being considered a breaking change.
```python
X_train_permuted = (
X_train_permuted.update(
pl.DataFrame(shuffle_arr, schema=features)
)

Not sure that I completely understood the problem ("cant detect scroll on separate sections") but I think I got what you are trying to achieve.
Below is a generic solution that calculates the scroll percentage of each div based on its top offset and height and sets the corresponding svg path length.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
var sect1 = document.getElementById("section1Wrapper");
var sect2 = document.getElementById("section2Wrapper");
var sect3 = document.getElementById("section3Wrapper");
var path1 = document.querySelector("#vectorPath1");
var path2 = document.querySelector("#vectorPath2");
var path3 = document.querySelector("#vectorPath3");
window.addEventListener("scroll", function() {
setPathLength(path1, sect1)
setPathLength(path2, sect2)
setPathLength(path3, sect3)
});
function setPathLength(path, sect){
let scrollPercentage = getDivScrollPercent(sect)
let drawLength = 2268.36 * scrollPercentage * 3;
path.style.strokeDasharray = `${drawLength}, 2268.36`;
}
function getDivScrollPercent(sect){
let rect = sect.getBoundingClientRect()
let top = rect.top
let height = rect.height
// start calculating the scroll percentage when rect top
// is between 0 (reached viewport top and -[div height] (scrolled out of viewport)
// otherwise return 0
if (top > 0 || top < -height) return 0
return -top / height
}
<!-- language: lang-css -->
#section1Wrapper {
background-color: black;
}
#section2Wrapper {
background-color: blue;
}
#section3Wrapper {
background-color: red;
}
<!-- language: lang-html -->
<!-- Section 1 -->
<div id="section1Wrapper" class="section-wrapper">

The existing code renders. However, when I remove `Router` from line 2 as an import, even though it's not being used, it breaks.
When I compile, of course I get "Line 2:27: 'Router' is defined but never used no-unused-vars"
Why is this? Or does anyone have any insight?
```jsx
import React from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import HomePage from './HomePage';
import PlanTripPage from './PlanTripPage';
import NavBar from './NavBar';
import ItineraryPage from './ItineraryPage';
import './App.css';
function App() {
return (
<div>
<NavBar />
<Routes>
<Route exact path="/" element={<HomePage />} />
<Route path="/plan-trip" element={<PlanTripPage />} />
<Route path="/itinerary" element={<ItineraryPage />} />
</Routes>
</div>
);
}
export default App;
```
Here is my index file.
```jsx
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import App from './App';
import './index.css';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById('root')
);

I have a frame (events) which I want to join into another frame (fr), joining on Date and Symbol. There aren't necessarily any date overlaps. The date in events would match with the first occurrence only on the same or later date in fr, so if the event date is 2010-08-29, it would join on the same date or if not present then the next available date (2010-09-01).
I've tried to do this using search_sorted and join_asof but I'd like to group by the Symbol column and also this isn't a proper join. This somewhat works for a single Symbol only.
fr = pl.DataFrame(
{
'Symbol': ['A']*5,
'Date': ['2010-08-29', '2010-09-01', '2010-09-05',
'2010-11-30', '2010-12-02'],
}
).with_columns(pl.col('Date').str.strptime(pl.Date, '%Y-%m-%d')).with_row_index().set_sorted("Date")
events = pl.DataFrame(
{
'Symbol': ['A']*3,
'Earnings_Date': ['2010-06-01', '2010-09-01', '2010-12-01'],
'Event': [1, 4, 7],
}
).with_columns(pl.col('Earnings_Date').str.strptime(pl.Date, '%Y-%m-%d')).set_sorted("Earnings_Date")
idx = fr["Date"].search_sorted(events["Earnings_Date"], "left")
fr = fr.with_columns(
pl.when(
pl.col("index").is_in(idx)
)
.then(True)
.otherwise(False)
.alias("Earnings")
)
fr = fr.join_asof(events, by="Symbol", left_on="Date", right_on="Earnings_Date")
fr = fr.with_columns(
pl.when(
pl.col("Earnings") == True
)
.then(pl.col("Event"))
.otherwise(False)
.alias("Event")
) |
After searching documents and online sources, I have came to this conclusion that the `unmanaged` constraint differs from 'unmanaged resources.'
unmanaged resources refer to resources that are not collected or managed by the garbage collector, while the `unmanaged` constraint in specifies that the type parameter of a generic type should be a non-nullable unmanaged type. Additionally, types with the 'unmanaged' constraint should not contain any reference type fields at any level of nesting.
So applying the `unmanaged` constraint to a generic type parameter does not exclude instances of that generic type from being managed by the garbage collector. The unmanaged constraint only specifies certain characteristics that the type argument passed to the generic type parameter must satisfy. |

I have started making a 3D Tile based farming game in Godot (inspired from Homegrown). I managed to make the Random Terrain and Camera systems on my own but am now struggling to make the terrain editing thing.
So the world is generated in tiles of primarily Grass, Farm and Pavement. Now I need a way to edit these tiles in the game by clicking on it. Although I have a logic in my mind, I am unable to implement it.
I need the access the tile by clicking on it with a mouse (I am a super beginner).
I am using this code to generate the world:
```
extends Node3D
var world_tile_array = []
@export var world_size = 10
var space_between_tile = 1
var generate_modes = ["Grass", "Pave", "Farm"]
func world_tile_array_generate(world_size):
var soil_tiles = load("res://scenes/tiles.tscn")
var tiles = []
for i in range(world_size):
for j in range(world_size):
var tile = soil_tiles.instantiate()
tile.position.x = i
tile.position.z = j
tile.set_mode(generate_modes.pick_random())
tiles.append(tile)
return tiles
func world_generate(tiles):
for i in tiles:
$Tiles.add_child(i)
func _ready():
world_tile_array = world_tile_array_generate(world_size)
world_generate(world_tile_array)
```
In the comments is the logic which I came up with and the world which is generated.
Please reference the video. How can I get a similar result?

How to edit tiles in a Godot game? |
this error can happen for a number of reasons but one way or another what's happening is that your PHP can't find your database to connect, here's a few suggestions on how you can troubleshoot this issue.
1 - verify the database exists
------------------------------
make sure that you have created your database before trying to reference in your .env file, sometimes we can get ahead of ourselves and end up skipping steps.
2 - verify the name of your database
------------------------------------
most likely in your .env file you are giving the wrong reference to the database and that's why you won't be able to connect, check for typos and make sure that the name on your .env is EXACTLY the same name as your database, note that this is case-sensitve.
these are the most common reasons to this type of error but if this doesn't help on your case please share a little more information, specially how you're trying to connect on the .env file of your laravel project. |

Why when we call a function in 'onclick' in the html document, that function is not read in a JavaScript Module file if there is an 'import'?
Is there a solution to use 'onclick' again in this case?
For example, 'onclick' calls the following:
`<input type="button" value="-" class="dark" onclick="mathfa('-')">`
This function:
```
function mathfa(ma) {
if (ma == "Percent") {
varable.po = false;
varable.eva = false;
varable.per = true;
if (varable.box.value.indexOf("^") == -1
&& varable.box.value.indexOf("+") == -1
&& varable.box.value.indexOf("-") == -1
&& varable.box.value.indexOf("*") == -1
&& varable.box.value.indexOf("/") == -1
&& varable.box.value.indexOf("%") == -1) {
varable.box.value += "%*";
} else {
varable.box.value = varable.box2.value + "%*";
}
} else if (ma == 'pow') {
per = false;
eva = false;
po = true;
if (varable.box.value.indexOf("^") == -1
&& varable.box.value.indexOf("+") == -1
&& varable.box.value.indexOf("-") == -1
&& varable.box.value.indexOf("*") == -1
&& varable.box.value.indexOf("/") == -1
&& varable.box.value.indexOf("%") == -1) {
varable.box.value += "^";
} else {
varable.box.value = varable.box2.value + "^";
}
} else {
varable.po = false;
varable.per = false;
varable.eva = true;
varable.box.value += ma;
}
}
```
In a JavaScript Module file:
` <script type="module" src="http://localhost:8080/scripts/script.js"></script>
`
I even put this function in another file and imported it in the main JavaScript file, but it didn't work.
In addition, I know that if I call that function by 'addeventlistener', it works, but as I mentioned, my problem is using 'onclick'. |
