Fe-26 is my team’s entry for Godot Wild Jam 68. I’m the coder. Made in one week. It’s our first 3D game: an endless runner where you play Felix, an iron cube trying to escape being forged.
I absolutely love Godot. Can’t wait to make the next game.

I built Pixels: disposable Linux containers for AI coding agents. Sandbox your agents on your own hardware with checkpoints, egress controls, and zero cloud costs.
MIT licensed, written in Go.

Pixels is a self-hosted, sandboxed container for agentic coding CLIs. Claude Code, OpenCode, Codex, you name it. Added session persistence using zmx.sh/, let it run overnight. 16 PRs merged while I slept. Total compute cost: $0.

Fast mode in @claudeai is great! It gives you the speed Opus had 3 months ago for more money!

I'm working on a secure #vibecoding sandbox using @TrueNAS virt instances and ZFS snapshots with my github.com/deevus/truenas-go library including checkpoints and rollbacks.
It's a CLI called "pixels". Still working on it. Stay tuned! #ClaudeCode #OpenCode #Codex

Hey #truenas people! Who likes TUIs?! I just published the first version of a TUI for TrueNAS. Read-only at the moment. Bugs expected! github.com/deevus/truenas-tu…

Over the weekend I tried Gas Town. I'm keen to see where it goes, but its likely not for me at the moment.
For me personally, Gas Town is giving too much away. I like to be more technically involved in the process of building software than Gas Town allows simonhartcher.com/posts/2026…

Is there anyone at @Steam @valvesoftware that wants to work with me to find out why Steam crashes constantly for me on Arch Linux?

Mental health can be a cruel mistress. I have so many things that I want to do, but my brain stops me. I discovered this year that I have dysthymia. It comes and goes like the tides. Sometimes low tide feels like it lasts forever. #MentalHealth

I never thought I would get on the front page of Hacker News. But last month I did! Here is my post lamenting the @FrameworkPuter 13 battery life. simonhartcher.com/posts/2025…

DAY 01 of GCAP starts! A massive congrats to @BigAntStudios on 25 years! That is huge. Man, that’s the dream right? The stories they could tell about surviving and thriving that long…!
If you’re about today, come and say hi! If you check out my full profile on the GCAP app you might find a surprise at the bottom… What? No! It’s not shameless self promotion or an offer of free things… I mean, what would I give away??
See you about!

@croloris Spent a few hours tinkering with Zine with posts coming from Notion. Pleased to report that I have been successful!
It runs a script with Bun to generate the .smd files for each post, along with saving any assets alongside the post.
Future = No more NextJS blog!

One of the snags I hit was that syntax highlighting is quite strict. I updated the renderer to just swallow those errors for now.
Why does it exit the process if highlighting fails?
