Mort d’une cycliste en 2025 – Montréal devrait créer un « lien cyclable » sur l’avenue du Parc, conclut une coroner.

Sur l'article, la photo du « die in » de la @MasseCritiqueMTL@jasette.facil.services de septembre dernier.

@cigitalgem @rasterweb @vees Il have to try that receptionist thing! My way of dealing with known scammers so far was to just leave my phone on mute and continue with my work. Most calls I receive don't connect the scammer until I press a key, so I'm certain it's a scam and every second they wait for an answer is a second they're not trying to scam someone else...

@TimWardCam @GossiTheDog For some additional context the whole point of downloading every time is so they can track the CVEs, I'm basically mirroring stuff between two systems and every build gets everything for dev, QA and prod. There's a tool to track and block builds and whatnot, but they decided on going a more drastic route. But the cherry on top was even the latest version still had CVEs, because X (an oss app release) bundles lots of software and apparently just can't keep up themselves.

@TimWardCam @GossiTheDog For us the deadlines are not so much a problem, we have them but what I work on RN is all internal apps on a secured network, not the risk exposure of online web apps fortunately. But being told I have to stick to an older version with CVEs because the latest version (which fixes at least one of said CVEs) still has open CVEs is mind blowing. Like, can't we at least make progress!?

Windows Subsystem for Linux: Process Architecture

Once we had a better architectural understanding of how the whole Windows Subsystem worked, I thought we should get more into how processes actually run in this new context. It turns out to be way more interesting than I would have otherwise thought thanks to our resident superhero Nick Judge. He dives into a new kind of process called a "PicoProcesses" which are a brand new lightweight, secure process infrastructure coming to Windows 10. I thought this sounded a little scary until Nick explaine

Windows Subsystem for Linux: Architectural Overview

In this video Deepu Thomas lays down the real scoop behind the Windows Subsystem for Linux. There was a lot of speculation surrounding how this feature actually worked so I decided to find out. This architectural overview gets into exactly how an operating system separates functionality into user and kernel mode. Deepu then uses that understanding to show how this new subsystem works in that context. The whole explanation is thoroughly enlightening and often stretched my understanding of how the

Windows Subsystem for Linux: Networking Overview

Exploring the Windows Subsystem for Linux, we have looked at the architectural overview, the Pico Processes, syscalls and filesystem. In this video we focus on the networking layer. Sunil Muthuswamy discusses some of the differences between Windows and Linux networking and where the translation happens. Sunil will also walk us through the translation of typical TCP and UDP calls as well as touch on how Unix sockets are used by Linux for inter process communication.

@hailey Is this like CoLinux? It was running User Mode Linux as a Windows process on XP, no virtualisation needed. Basically WSL2 way ahead of it's time! The only caveat is that it relied on both arches having compatible pointer sizes which excluded 64bit, so it was never ported to win7. On a technical aspect though WSL1 is IMHO even better than it's successor, it's literally implementing POSIX and Linux on the NT microkernel. After all NT was supposed to also run OS/2 and Xenix...

Exploring the Windows Subsystem for Linux, we have looked at the architectural overview and deep dived into the Pico Processes. In this video we focus our attention on the way the subsystem redirects system calls. Stephen Hufnagel will explain how system calls work in general on Windows and Linux, then dive into the mechanics of WSL's translation. He'll discuss system calls which are easily mapped, as well as some which are a little more difficult. The more I get to dive into this awesome techno

@mirabilos @hailey Well, that said WSL1 didn't come without any drawback:

  • Slower local file access (files were stored natively on NTFS, even trough a VM Linus on ext4 is faster)
  • Cross-os file changes caused weird permission/ACL issues
  • Not all Linux ABI / interfaces were implemented (and this is a moving target!)

That last point is important, for ex. Debian Trixie fails on WSL1 because new passwd locking isn't implemented in the NT kernel. New interfaces would require support too.

Since then, we have explored an architectural overview, how Pico Processes work, System Calls redirection and File System support. Today we explore a new WSL feature: the ability for WSL to call Windows executables, and for Windows to call Ubuntu binaries. Ben Hillis will deep dive into the inner workings of our most requested feature and show how these two environments can complement each other in some very interes

@mirabilos @hailey They actually fixed it, you can use host networking in recent versions. That matter a lot for me as I prefer using Vcxsrv for the X server. Theirs is broken on non-US keyboards and I don't need 3D. And besides, I've been using X apps long before WSL "supported" them. IIRC initially we could use the resolver's IP but they locked out down, and then whatever solution caused X apps to randomly disconnect. But I have it 100% stable again. Happy to share my setup when I'm home...

Windows Subsystem for Linux: File System

One of the key goals for the Windows Subsystem for Linux is to allow users to work with their files as they would on Linux, while giving full interoperability with files the user already has on their Windows machine. Unlike a virtual machine, where you have to use network shares or other solutions to share files between the host and guest OS, WSL has direct access to all your Windows drives to allow for easy interop. Windows file systems differ substantially from Linux file systems,. In this vid

When your case has no PC speaker... A breadboard and a couple LEDs to see the beeps! 😀

It turns out no my clumsy CPU installation method did not break the motherboard. A DIMM was badly seated and popped out during the CPU replacement process. Rush mobo replacement order cancelled in time...

Who's the idiot that decided a PC speaker was optional?!?!?

And TIL "Speaker Out" is actually a sink, has to connect with +5v...
