Show HN: AI Physics Tutor with Free Body Diagrams

Hi HN. I built a prototype AI physics tutor that can interpret, draw, and edit free body diagrams.

Lately I've been transfixed with generating diagrams with LLMs. If you pipe generated JSON through a D3.js renderer, you can get pretty consistent SVG results with the smarter models.

This physics tutor prototype is an example of an application. For a couple premade scenes, you can ask it to make an FBD, decompose an angled force into components, run through the math of Newton's Second Law,

Show HN: Voltpeek – Vim-inspired oscilloscope software

This is software for my headless, PC based oscilloscope, which is controlled entirely via commands similar to the Vim text editor. I built this because I liked the idea of headless oscilloscopes; I always have my laptop around when I’m working on electronics anyway, and it’s very convenient to save images of captured waveforms. However, I found the software for off the shelf models to be annoying and cumbersome to work with. In my experience, this holds true both when opening the software an

 This is Microsoft's canceled Windows-based Surface Duo — the dual-screen Windows Phone from 2018 that we never got

Surface Andromeda was the successor to Windows Phone we never got. Now, we know exactly what it would have looked like thanks to leaked images of prototype hardware from 2017 and 2018.

Disk z Faistu

Unikátní předmět z minojské Kréty, starý přibližně 37 století. Tajemné znaky uspořádané do spirál fascinují. Nejspíš je to pravé. Dál nevíme a můžeme jen mapovat dobové a místní souvislosti. http://www.osel.cz/14185-disk-z-faistu.html

Show HN: NaturalCron – Human-Readable Scheduling for .NET (With Fluent Builder)

Hi HN!

I built NaturalCron because I was tired of writing and debugging CRON syntax like:

/5 * * 5

Now you can write something human-readable in .NET:

var expression = new NaturalCronExpression("every 5 minutes on friday");

Or use a Fluent Builder for strong typing and IDE support:

var expression = NaturalCronExpressionBuilder .Every().Minutes(5) .On(DayOfWeek.Friday) .Build();

Great for: - Code-based scheduling in .NET apps - Overriding schedules from confi

Radikálně překódovaná bakterie Syn57 má doposud nejmenší genetický kód

Molekulární biologové vzali E. coli a její genetický kód ořezali o celkem 7 kodonů. Namísto původních 64 jich zbylo využitých 57. Vznikl kmen Syn57 s komprimovaným genomem. Uvolněné kodony bude možné využít v biotechnologických aplikacích. Tvůrci Syn57 sázejí na to, že takové bakterie budou nepřístupné virům. Zkušenost ale říká, že to nejspíš nevydrží věčně. http://www.osel.cz/14184-radikalne-prekodovana-bakterie-syn57-ma-doposud-nejmensi-geneticky-kod.html

Show HN: Wordle-style game for Fermi questions

Some months ago @andrewrn tried to create a Wordle-style site for order-of-magnitude thinking. This was a wonderful idea, but the actual site was somewhat over-engineered and confusing. (https://news.ycombinator.com/item?id=43632278)

In the past week, I looked at this idea again and built a very simple site which gives you a new Fermi estimation question every day:
