WSL:Ubuntu in Visual studio code - losing connection
1 January 2026 @ 2:49 pm
I set up visual studio code to code with python using Windows 11.
I wanted to use a package for python called sage (math software), but to use it with windows I need to connect to WSL:Ubuntu.
Now, everytime I start vsc it successfully connects to Ubunute, but loses connection after 1 or 2 minutes. A window pops up saying it tries to reconnect, but this is never succesful. Only restarting helps.
Since I need to execute a program which takes more than a minute, this is a problem for me.
For the remote-connection to Ubuntu I am using the extension WSL v0.104.3, which is the newest one I could find. It also says that there are no updates for VSC.
Is anyone familiar with this problem?
Thanks in advance.

GSAP Flip animation blink/glitch only the third element works fine
1 January 2026 @ 2:26 pm
I’m using GSAP Flip to animate images from a grid of cards into a detail view by reparenting the clicked image. The animation works correctly for the 3rd but the 1st and 2nd and 4th cards show a brief blink / jump during the transition.
What’s confusing is that:
All cards use the same markup and logic
The glitch happens only on the first row
There’s no console error
The issue is visible for ~1 frame (looks like a layout or transform jump)
Environment
GSAP 3.12.x
Flip plugin
Chrome / Edge (reproducible)
CSS Grid layout

XAMPP Apache and Mariadb not starting on Windows, localhost not loading Body: [closed]
1 January 2026 @ 2:16 pm
I am using XAMPP on Windows 10. I am trying to run a local server using localhost for a basic Mariadb setup.
Issue:
XAMPP starts, but Apache and/or Mariadb fail to run consistently
When I open http://localhost, the page does not load
Sometimes Mariadb throws an “Access denied” error, other times the service does not start at all
What I’ve tried:
Restarting XAMPP as administrator
Stopping Mariadb service and starting it again
Checking port conflicts (Apache on 80, MySQL on 3306)
Errors observed:
“Access denied for user '@localhost'”
“Not enough memory resources available” (intermittent)
What could cause XAMPP services to repeatedly fail on Windows, and how can I stabilize the local server setup?
How to stop my THorse controller from executing after the middleware send a 401
1 January 2026 @ 2:13 pm
I am trying to build an api in Delphi 12 CE, using THorse.
I have setup middleware to handle the authorization, but it does not stops there.
my project file (simplyfied)
begin
dmMain := TdmMain.Create(nil);
TTokenStore.Initialize;
// Activate JSON middleware
THorse
//.Use(Jhonson())
.Use(AuthMiddleware);
RegisterAuthorizationRoutes;
TMainController.RegisterRoutes;
Writeln('Horse MVC server running on http://localhost:9000/');
THorse.Listen(9000);
TTokenStore.Finalize;
end.
my middleware
uses
Horse, System.SysUtils, TokenStore, Winapi.ActiveX, Horse.Exception, Horse.Commons;
procedure AuthMiddleware(Req: THorseRequest; Res: THorseResponse; Next: TProc);
implementation

How to set LZ4_NBWORKERS?
1 January 2026 @ 1:44 pm
I am using LZ4 v1.10.0 - Multicores edition. I would like to set LZ4_NBWORKERS to take advantage of multi-core CPUs:
import subprocess, time, platform, sys, os
# Information of the system
print('OS:', platform.platform())
print('CPU:', platform.processor())
print('Number of logical cores:', os.cpu_count())
print('Python:', platform.architecture()[0], platform.machine(), sys.version)
# Paths
tarPath = "tar" # Windows 11 has tar.exe on PATH
lz4Path = r"C:\Users\Akira\Downloads\Compressed\lz4_win64_v1_10_0\lz4.exe"
srcDir = r"E:\Personal Projects\tmp"
filesToArchive = ["chunk_0.ndjson", "chunk_0.ndjson"]
outLz4 = r"E:\Personal Projects\tmp\test.tar.lz4"
# Version of lz4
print()
result = subprocess.run([lz4Path, "-V"], capture_o
Lifetime of temporary to which a local reference is bound in a c++ coroutine
1 January 2026 @ 11:41 am
On cppreference (which I understand is not the c++ standard itself) I have read that the coroutine state contains "local variables and temporaries whose lifetime spans the current suspension point.", (emphasis mine) but I don't think I understand how this works.
Suppose I have a coroutine that looks something like this:
/*...*/ SomeCoroutine()
{
const auto& ref = std::string("abc");
co_yield ref.size(); // assume the coroutine really does suspend
co_return ref.size();
}
Before the coroutine is suspended, is ref a local variable on the stack, or is it really a member of the coroutine state (in which case I doubt it can actually be a reference)?
After the coroutine is resumed, is ref a local variable on the stack, or is it really a member of the coroutine state? If it is still a reference, is it dangling now, or did the string get
PySide6 QOpenGLWidget flickers even with minimal example inside a layout
1 January 2026 @ 11:25 am
I am experiencing flickering when using QOpenGLWidget with PySide6,
even with a minimal setup.
Environment:
- PySide6 (tested with 6.5 / 6.6)
- Python 3.x
- OS: Linux / Windows (happens on multiple systems)
- GPU drivers: standard system drivers
Minimal reproducible example:
import sys
from PySide6.QtWidgets import (
QApplication, QMainWindow, QWidget, QVBoxLayout
)
from PySide6.QtOpenGLWidgets import QOpenGLWidget
from PySide6.QtGui import QSurfaceFormat
from PySide6.QtCore import Qt
class GLWidget(QOpenGLWidget):
def initializeGL(self):
pass
def resizeGL(self, w, h):
pass
def paintGL(self):
# No dibujamos nada a propósito
pass
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
central = QWidget()
layout = QVBoxLayout(central)
self.gl = GLWidget()
layout.addWidget(self.gl)
self.setCentralWidge
lambda boolean equality operator usage without outer triger mechanism
1 January 2026 @ 10:09 am
I'm just hanging out and trying freecodecamp lambda built-in function for code exercise using Learn Lambda Functions by Building an Expense Tracker python course section...
lambda expense: expense['amount'], expenses)`
So, lambda x: x * 2 is an example which is obvious...
then
lambda expense: expense['category'] == category is a usage for filtering out mechanism usage scenario as an example:
expense1 = {'amount': 10, 'category': 'Food'}
expense2 = {'amount': 20, 'category': 'Travel'}
category = 'Food'
check = lambda expense: expense['category'] == category
print(check(expense1)) # True → true
print(check(expense2)) # False → exact violation and filtering out

2026 Predictions: The Next Big Shifts in Web Accessibility
22 December 2025 @ 11:22 pm
I’ve lived long enough, and worked in accessibility long enough, to have honed a healthy skepticism when I hear about the Next Big Thing. I’ve seen lush website launches that look great, until I activate a screen reader. Yet, in spite of it all, accessibility does evolve, but quietly rather than dramatically. As I gaze […]

Accessibility by Design: Preparing K–12 Schools for What’s Next
30 July 2025 @ 5:51 pm
Delivering web and digital accessibility in any environment requires strategic planning and cross-organizational commitment. While the goal (ensuring that websites and digital platforms do not present barriers to individuals with disabilities) and the standards (the Web Content Accessibility Guidelines) remain constant, implementation must be tailored to each organization’s needs and context. For K–12 educational agencies, […]
Up and Coming ARIA
30 May 2025 @ 6:19 pm
If you work in web accessibility, you’ve probably spent a lot of time explaining and implementing the ARIA roles and attributes that have been around for years—things like aria-label, aria-labelledby, and role="dialog". But the ARIA landscape isn’t static. In fact, recent ARIA specifications (especially ARIA 1.3) include a number of emerging and lesser-known features that […]
