Hot take: AI isn’t dangerous because of how intelligent it’s gotten, it’s dangerous because how cheap it is

30 years ago my game The Adventures of Lomax for the PS1 was release this day the 22th of October 1996 in the US. Great memories developing this with just 2 team members. Me doing all the artwork, game-design and world editing. Erwin Kloibhofer coding the game and editor. Time flies!

Hi, everyone! I'm still working hard on the Katana ZERO DLC. We made it bigger. It's the size of a full sequel, plus a soundtrack of over 30+ new songs. More updates to come. Thanks for your continued support!

Today in "you can just build things" I got tired of sites having terrible dark modes, so I made a claude agent plugin for chrome that lets me customize themes for any website. Now look at how good my twitter looks!

I've seen about 5 other window managers all launch around the same time as trellis, and interestingly they are all nearly identical - a single horizontal strip. Why they all converge on the same thing? I'm not complaining, gives more room for Trellis to stand out.

for a product to be truly great it needs to be idiosyncratic and reflect the builder's ethos/uniqueness if it does this, you needn't worry about competition, and there's many ways to approach distribution if you feel one avenue is no longer tenable

TrellisWM 0.9.6 is out 🌿 • New rendering engine: smoother, more reliable animations • Pinch and pan now need ⌥, so the Desk doesn't zoom or pan by accident • lots of fixes and performance improvements trelliswm.app
