Ask HN: What are you working on? (September 2026)
The app wraps whatever is playing on mac through device convolution (old radio, hifi system) - Room convolution (a bedroom, a forest) and adds ambience (rain, wind, waves) and Apples spatial processing - so it sounds like a real space.
For me - hearing the sound in a space really helps more than just the dry sound.
I remember someone saying that when you build a game, you end up building tools to help you build the game. I never really got that, but now I do. I've spent quite a bit of time working on tools to help me balance the various game mechanics.
One weird learning, it was much easier to get it on the iOS app store, than the Google Play store. Google wants you to have a closed playtest with at least 12 players, for 14 days. I did that and they said the testers weren't engaged enough.
If you want to check it out on iOS https://apps.apple.com/us/app/fairway-rogue/id6783598189, I'm still trying to get it on Android
TUI file manager with Bitwarden/SFTP/S3 support written in go.
Runs pretty much anywhere.
Current feature in the works is built-in audio player.
As someone who still likes to purchase and organize music in files and directories, I couldn't resist the itch to code a worthy competitor to Cubic Player :)

Have been running an in-school pilot over the last school term. Has been super insightful and led to a heap of changes to optimize UX. However, the biggest challenge has been delivery in this environment.
Trying to run a game in a browser on school iPads powered by really locked down networks has been challenging. Some school iPads will crash (out of memory) when launching the camera view, whilst others run flawlessly. We use a fork of Godot, and are constantly fighting to strike a balance between UX (increased parallelism) and browser device constraints i.e. a limit on how many web workers we can fit in memory.
In addition to our main (build and play your own RPG) experience, we also stream games direct to iPad. In particular a modded version of Overcooked! 2 that teaches kids to code — Overcooked itself was never even released on iPad. We've built our own Kubernetes system that spins up (a license limited number of) games/pods on demand backed by (time sliced) NVidia GPUs. This is literally running out of my home office. Despite the complexity of building all that, the Kubernetes and GPU time slicing wasn't even the largest hurdle. Turns out UDP is a no-go on the school network, so direct WebRTC was out the window. Instead we're using Cloudflare's TURN relay with TCP. Which much to my surprise, is holding up quite well.
Definitely a learning experience. However, kids are having a blast. Can't wait to roll this out further!
You would be surprised at how many over / suboptimally-provisioned dbs, idle resources, forgotten EBS snapshots, outdated / previous-gen instance types, and vestigial networking that leads to nowhere I find.

It’s been really fun working on it and especially rewarding seeing the game bring friends together.

I am building a new kind of LLM runner which lets you understand the internal reasoning process, and which can be automated to intercept hallucinations and prompt injections before they cause more damage.
(No public code yet, but I do intend to open source it)
Been working on Feedbun for a little while, Elixir/Phoenix stack, with bespoke LLM fleets for production workflows. Recently just started using React Native (Expo) for the companion mobile app so I can use it when I shop IRL.
Also started working on a 2D strategy game using Godot engine, still super early days. Been fun to experiment with different LLMs capabilities on game development.
