The threat of AI to search says more about search than it does about AI.

My static micro blog experiment is going better than expected. Generation is still around 25 seconds hot on my old laptop as like the last time. Well… sneakily it’s closer to a semi–constant 5~10 seconds by tricking hugo into outputting empty base templates which “can” result in mostly reads by writing files that have changed (might make a blog post about this).

This blog becomes mostly complete (minus the sharp edges) when there’s an archiving strategy on the paginator — basically a ghetto queue.

The Enhance Framework looks compelling. Personally, web components and more particularly the shadow DOM are not very appealing but… the template structure looks clean for drawing up components/layouts super fast while still being primitive enough to not lose transposability between different environments.

It seems like there’s an uptick in discussions online around web components but maybe that’s just the typical developer marketing/advocating. Web components have been around for a bit.

Look at this Makefile — then look at this NixOS package derivation. Appears simple but I couldn’t for the life of me divine how to quickly compile a custom/patched kernel module on NixOS. Abstractions… are very magical. The guide is cool and all, but it’s a better time investment to guesstimate the relationship between the higher/lower layer. This friendly example looks more like this in reality though ;-)

Then build it as a extra/custom kernel module. The results of stumbling upon yet another troublesome device…

  
  
    nix
  
  
  { pkgs, ... }:

{
  boot = {
    extraModulePackages = [
      (pkgs.callPackage ../packages/snd-hda-cs8409/default.nix {
        kernel = pkgs.linux_5_15;
      })
    ];
  };
}

Bots are ≈ 80% noise. It’s funny that in general analytics are not needed anymore. 80% noise and 20% signal. 80:20. It’s safe to turn off the computer and head outside — you’re not missing much when not on the Internet (it’s smaller than you’d think signal–wise).

I had some time to futz about updating my Isso setup and forgot that a while back they added Atom Feeds. It’s also neat that it uses Atom Threading (an example). Installation from source is easier too.
