A web app (PWA) for logging tinnitus episodes - Mimi Memo: https://mimimemo.com/

Developed for my personal use but publicly available and open source. I’m pretty happy with the current state so don’t expect a lot of updates and features, but hopefully others might find it helpful.

Not quite.

- The 43% is peak drag reduction in the transition zone only, the bit between laminar and turbulent flow, not across all flight conditions.

- Aerodynamic drag is one part of fuel burn, not a 1:1 proxy. There's also engine efficiency, etc.

- This is skin friction drag on a wind tunnel model, not a full aircraft which has extra bits like windscreen wipers.

I still think it's exciting but I reckon fuel savings would amount to a few percent (aeronautical engineers, please correct me if I'm wrong).

Ménière Memo, a web app for logging and reviewing Ménière's Disease episodes:

https://menierememo.com/

Intended for an audience of one so still a bit rough around the edges, but the intended audience said “excellent” and is actually using it.

Mostly AI-built. Source code is here:

> Data centers can inadvertently pollute water through chemical runoff from evaporative cooling systems, including biocides, corrosion inhibitors, and heavy metals that accumulate at scale when facilities discharge up to 5 million gallons daily.

The knot codes are beautiful but the ones in the article all seem to be repeating patterns, so I wonder if you could take a 60° slice of each one and save space without losing information.

If you're in the north of England the Derby Computer Museum is nicely maintained and presented. Exhibits are pre-2000.
