Ask HN: What are you working on? (September 2026)
Now working on releasing on steam, android, ios. Also made an ssh version you can access via your terminal [2]. Hoping could get as many downloads in native platforms.
It's mountaineering safety tool I've been making for my friends and I.
The fun part: if your browser has WebGPU, the page solves that field live as a compute shader (about 35 ms on an Apple GPU) as you scrub the timeline, and draws the flow over a 3D terrain view. Browsers without WebGPU get a precomputed field.

Ranges and uncertainty only, no go/no-go verdicts. That still requires your best judgement as a mountaineer. Next up is a free-play mode where you set the wind direction and speed yourself and watch the field re-solve.

In that project, I also proposed a tool with heavily redundant password protection that parents could use to keep kids from tampering with the service so the government can stop saying that this is for the kids. I'm planning on doing a mobile device version and/or an ID database focused version, but that's still in the planning phase.
I also want to do a Windows version when they release their 'GetUserAgeRangeAsync' API, but idk if I'll be able to. Windows is always a pain to work with.
It'd be nice if someone had advice or ideas to share, too.
I set out to solve that with https://stayupfront.com and now that the build is in a good place i’m finally having to bite the bullet and learn marketing. I’m also realising that all the advice to start with marketing first was probably good advice!
Won’t that make it difficult to rotate your keys?
Keys should be something you don’t hesitate to throw away and rotate at the first hint of a compromise.
I think this is a good balance point, and I estimate that if we want to rotate the keys completely in the future, we should start using new key algorithms. (I estimate it will take another 5-8 years)
Yes, when certain situations arise, it is necessary to rotate the keys as soon as possible, but in the absence of such situations, losing key backups can be catastrophic.
Clusters ready to deploy you applications on. It is meant for companies who want their own private infra, but do not want to maintain it. It is multi cloud, with a focus on europe.
Our secret weapon is “Menno”: an assistant which helps you setting up the cluster and deploying applications. We use the assistant for handson demo’s and workshops and got some really good feedback on it.
I started it because I wanted simple brain-training exercises that didn’t require an account, app install, or subscription.
It’s also open source: https://github.com/loethen/freefocusgames
They are sorted by predicted aesthetic rating and can be filtered by time of day, color, orientation, and park.
