Lots of awesome OS for the PDS posts flying around today, but what about a PDS in the OS? Here's a peek at the native Linux rewrite of @aetheros.computer, built on NixOS with PDS backed user accounts and experimental support for spaces. Still WIP, but stay tuned for more info later this year...

Got my Retroid Pocket Nova yesterday and it’s def become my favorite handheld for retro gaming. It has a 4:3 OLED screen and emulates everything from 8-bit to 128-bit consoles flawlessly. It’s also android based and incredibly easy to hack on 🤩

Having so much fun messing around with this. I wanted to stress test the 3d editor for @brickster.at and ended up making a Death Star trench diorama. The editor has a bunch of new builder tools and you can now invite up to 12 people to edit together using your atproto handles.

New atproto app idea I demoed yesterday where you record what you’re grateful for and tag someone. Each orb is a recording, and is used to power a generative synth for a dynamic ambient soundscape. Definitely zoned out to this last night 👽

That's a dope idea. You'd only have to create the record with a couple of required fields for it to display correctly, most important ones being lat/long and venueUri. venueUri uses openstreetmap IDs to keep track of venues and group their check-ins. lexicon.garden/lexicon/did:...
{
  $type: "app.beaconbits.beacon",
  venueUri: "osm://way/123456",
  venueName: "Example Event Venue",
  visibility: "public",
  location: {
    $type: "community.lexicon.location.geo",
    latitude: "49.2606",
    longitude: "-123.2460",

Here’s another #screenshotsaturday gamedev log for my Godot voxel game. Today I added settlements with trade routes, sky islands with airships, and a sweet selfie debug camera. The game now also has a dynamic music system with some of the first VGM I’ve composed in a long ass time. Sound on 🎼

Taking time this holiday weekend to work on my Godot voxel game prototype some more. Already added some cool new features like traversal by foot, a dynamic skybox with weather, more lush biomes and a bubble shield for combat. #screenshotsaturday #gamedev
