Imagine this: it's Sunday afternoon at 1pm, and you want to watch some live content. But you don't have a TV subscription. So you do a little Googling, and eventually you find yourself on a sketchy website where you can watch the content you're looking for. But while the website has a video player, it's surrounded by advertisements, and probably a cryptominer too. You don't want this website eating your CPU for 2 hours while you're watching your favorite Sunday afternoon content.

Wouldn't it be nice if you could watch that video in VLC instead? Then you can close the sketchy website and still watch your content. It's like having your cake and taking a bite of it too!

Here's how you do it:

Capture the m3u8 request in dev tools. Open the site (or just the iframe, if possible) in DevTools and click "play." Search the network tab for m3u8 and grab the first request.
Run VLC with command line flags to set the User Agent and Referrer. From the request body, you need to copy the requested URL,

by the time you're reading this, this probably no longer works since the policy has been removed. I reccomend you to check out https://github.com/r58Playz/uBlock-mv3 instead

How to keep using adblockers on chrome and chromium

google's manifest v3 has no analouge to the webRequestBlocking API, which is neccesary for (effective) adblockers to work
starting in chrome version 127, the transition to mv3 will start cutting off the use of mv2 extensions alltogether
this will inevitably piss of enterprises when their extensions don't work, so the ExtensionManifestV2Availability key was added and will presumably stay forever after enterprises complain enough

You can use this as a regular user, which will let you keep your mv2 extensions even after they're supposed to stop working

Introduction

In this post, I will provide the solution that worked on my system on how to install Radeon Open Compute (ROCm) on Arch (linux-6.6.7.arch1-1) for RX 6900 XT (Should work on other 6000 series). ROCm is an open-source software platform that allows GPU-accelerated computation. This tool is a prerequist to use GPU Acceleration on TensorFlow or PyTorch. In this guide I will use Paru as my AUR package helper, feel free to use any other (https://wiki.archlinux.org/title/AUR_helpers). I will assume you have a working operating system and know what you do with it (Otherwise Arch will be painfull for you).

Gitea docker (rootless) without SSH passthrough

Official gitea docs are heavily focussed on doing SSH passthrough from the host machine to the docker container. An alternative is to simply run SSH for Gitea on a different port. Though I had some problems getting this docker compose setup to run. This gist contains my setup I finally came up with: It does not require SSH passthrough from the host to the docker container but still offers support to git clone via SSH.

To check if this setup works for you simply follow these steps:

Place enclosed docker-compose.yml in a directory.
Run docker compose up
Visit http://localhost:8033/ and simply install Gitea with given defaults

preface: Posting these online since it sounds like these notes are somewhat interesting based on a few folks I've shared with. These are semi-rough notes that I basically wrote for myself in case I ever needed to revisit this fix, so keep that in mind.

I recently bought an LG ULTRAGEAR monitor secondhand off of a coworker. I really love it and it's been great so far, but I ran into some minor issues with it in Linux. It works great on both Mac and Windows, but on Linux it displays just a black panel until I use the second monitor to go in and reduce the refresh rate down to 60 Hz.

This has worked decent so far but there's some issues:

It doesn't work while linux is booting up. The motherboards boot sequence is visible just fine, but as soon as control is handed over to Linux and I'd normally see a splash screen while I'm waiting for my login window, I see nothing.
It doesn't work on the login screen. This would be fine if login consistently worked on my second screen, but I need to manually switch
