Ask HN: What Are You Working On? (March 2026)
Originally I made it for my grandpa, but I got a lot of interest so I made it into a full commercial product.
Just yesterday I published a set of 3 mini tutorials if you want to see how it works - https://youtube.com/playlist?list=PLKt1F5TvOjAHE07oBDlPXcrHc...
When training I like to have every day mapped out with how many miles to run, at what pace, etc as an event in my calendar. My actual workout gets uploaded into Garmin and Strava, but I always wanted it back in the calendar so I could see at a glance the consistency over time. It's been really fun to see other people use and get value out of something I built for myself.
also just posted a Show HN thread: https://news.ycombinator.com/item?id=47310543
- Portable Secret (https://alcazarsec.github.io/portable-secret/) - self-contained HTML files that decrypt in the browser.
- Dead Man's Switch (https://alcazarsec.com/deadmanswitch) - sends messages when you stop checking in.
- Flare (https://alcazarsec.com/) - silent alert when your device is accessed without authorization.
I ask because I was recently thinking about how to preserve information for the future like this
This seems unlikely, however, since our infrastructure costs for the dead man's switch are covered by just a handful of subscriptions. Besides, we host it next to our other more profitable main product, so it gets free maintenance.
We are up for the challenge of making this last for many decades, though. It is a beautiful mission.
It's heavily supported by Claude Code, but much fun.
Actually not built on this yet I think, but I could switch over, haven't made anything more of it since it's still a bit rough around the edges, and I keep finding various issues during actual usage: https://binschema.net/
i don't have much free time, but it's important to me to have healthy side projects, so here's what i'm working on:
- rsyncthing: A command-line CLI that lets users quickly bootstrap Syncthing fileshares to new hosts over SSH. No more "introduce devices to each other" song-and-dance.
- stringlines: i'm working on a small app for my own personal use that will help me plan transit in the NYC area better. A lot of map apps (Apple, Google, Transit, Citymapper) don't show recently-departed trips, making them much less useful for judging the feasibility of tight connections on the NJTransit rail lines. So I'm building out some infrastructure to record the GTFS-RT feeds and display them in a mobile-friendly format.
- slowly playing through all 70 the quake brutalist jam III maps to learn more about level design.
Most of these side projects are claude-free for now, mostly because I want to build domain expertise for myself before involving the agent tooling.
I've been working on a solution to automate solar+battery use to arbitrage the market. I'm on a real-time utility plan but even if you're on TOU it can save you $1+ per day by strategically planning when to use the battery and when to conserve or charge the battery. So far it's limited to a few providers and only FranklinWH batteries but I'm eagerly looking for someone to help me get Powerwall support working and other ESS. It's open-source on GitHub as well.
It’s a drop-in replacement for Redis written in Rust. Most if not all of your client code should work without issues. Outperforms in many areas and has more out of the box features like proto storage, raft/swim, and encryption at rest.
I’m pretty proud of it, and I hope you’ll give it a shot and open bug reports. :)
