NixOS superpower: specialisations

NixOS has a lot of configurability and features. One feature that I’ve known about for a while that I think is both really cool, but also a bit lesser known is the ability to have declarative Specialisations. To me, this is a superpower of NixOS that I have a hard time to see any other Linux Distribution having. What’s a Specialisation? The name doesn’t do it justice, it’s a bit of a weird name for it.

A personal adventure with hot beverages

My history with coffee I’ve never been into coffee, every time I’ve tried them as a child or young adult they have been terrible. They have just been bitter and it’s not a taste profile I to this day enjoy at all. I have, a couple of times encountered coffee that friends have made that actually weren’t that bitter. So my reaction to it has managed to reach the level of “this isn’t terrible”.

AI should be trained with vegan values

As artificial intelligence (AI) continues to advance, concerns have been raised about the potential dangers of AI becoming too powerful and taking over human civilization. In a recent interview, entrepreneur and CEO Elon Musk expressed his concerns about the risks associated with developing super-intelligent AI. However, his views were challenged by Larry Page, co-founder of Google, who referred to Musk as a “speciesist” for not wanting AI to become a “digital god”.

Outsourcing NixOS compile time to Microsoft

NixOS is a Linux-distribution that may be source-based, but it has a binary cache that covers things so you generally don’t need to compile things, things tends to be cached. However, depending on how you configure your system, you may trigger compiles depending on what you do. So a thing I do is that I run Emacs 29 with the native-comp patches that is wayland native with the pgtk-branch. This is by no mean the stable Emacs release at the point of writing.

Keeping LG webOS Developer Mode alive with Home Assistant

For over 10 years I’ve used Kodi on a separate PC connected to a TV to play back local media. A couple of weeks ago everything changed in a matter of days. I listened to Late Night Linux – Episode 179 where they talked about Jellyfin. I have looked into Jellyfin before, however I’ve disregarded it due to the lack of app for LG webOS. This changed because the podcast episode told that there was a webOS app for Jellyfin.

First impressions of Purism Librem 5

Back in 2017, this fairly small company Purism launched a crowdfunding on their own crowdfunding platform for their future phone known as Librem 5. I went back and forth a bit, I thought through some of the history about the company and decided that I thought they may deliver some day. At least I wanted to support the effort to make a modern Linux that could fill the hole that the demise of the Nokia N900 with no worthy device following up.

Dynamic CSS color themes with similar contrasts

This blog is built with Emacs, SCSS using Nix and deployed as static files to GitHub Pages. This blog also has quite some colors due to the syntax highlighting for code that is performed using CSS rules on HTML classes. So in total I have 15 different colors defined, in which four of them is background and foreground colors, two of them is related to link and visited link colors. Then I have nine colors remaining which are related to syntax highlighting of code.

Simple deployments of NixOS machines with nixus

Since I’ve started using NixOS about four years ago I haven’t really used any tools to do central deployments of machines. But I’ve always read and known that NixOS is excellent at this. NixOS can easily build another systems configuration, then copy the system to the target systems nix store and then activate it there. Despite knowing all this, I haven’t gotten around to doing this centrally. A while ago the need for this changed because one of my VPSes started running low on RAM, low enough to not be able to build new generations of it’s own system.

NixOS: Setting up Push To Talk in Mumble on Sway

Switching to Wayland has it’s side-effects, one of which is the improved security from X11 where applications can’t just randomly spy on each other at any point. This is both good news and bad news. The good news: Applications can’t just randomly spy on each other. The bad news: Things like global hot-keys in for example Mumble won’t work. Back from complaining to actually solving the problem though. Mumble does have a patch for a future release So there’s the issue about Push to talk does not work in Wayland, this has been followed up by a patch Add DBus calls to de/-activate push to talk.
