I am currently developing a great encryption tool for long-term highly confidential files in the post quantum era, but I am still concerned about any issues with it, so I am personally using it for a period of time to prove that this tool can be released as open source! (I plan to personally use it to encrypt and backup some of my GPG keys offline, then burn them onto M-DISC discs and store them in a bank safe)

#252https://curvefit.app
it's a weight-training app that helps you train along your "pareto frontier" of weight vs reps. The idea is to train at lower weight-higher rep, medium weight medium reps, and higher weight, lower reps for every movement. I tried to develop my own weight training program following bits and pieces of advice from bodybuilding forums and ended up injuring several tendons in my first year. So I did a bunch of research on tendon strengthening as well as what's most effective for hypertrophy (reps near failure) strength (reps near maximal load) and injury-prevention/frequency (not bringing yourself to failure too often) and designed an app to automatically prescribe and advance weights and reps based on your learned strength curve (Brzycki-like, with an added shape parameter)
The app is designed to make use of the free Cloudflare tier, so I can support thousands of athletes for just the cost of the domain name. I'm primarily interested in understanding the "Fatigue curve" - right now I have some basic per-set fatigue modeling (basically a log-linear strength dropoff) but I think it could be much better characterized with more data. I could go on and on about the modeling but my intention is to keep it free (maybe add some non-intrusive ads on content pages if it ever starts costing me a few pennies a month) but my primary interest is to be able to do statistical analysis on the data.

#253I'm working on a Zettelkasten notes app that focuses on getting the UX details right. It takes aspects of Notational Velocity, outliner apps, Zettelkasten, and wikis and combines them into an opinionated Mac app.
What makes the app a little different from others is that it's kind of halfway between an outliner and a wiki. You can place notes in a tree hierarchy, but they can be free-floating as well. You can link to other notes using wiki-style text links, and each note has a unique address, so you don't need to give notes a title or a filename.
Notes can even appear as a child note of more than one parent. The idea is that you can jot down an idea quickly without a lot of friction and then later either add sub-notes to create a note "tree" from it or add it to an existing tree. The tree gives structure to related notes, but the wiki-style links allow you to connect notes together outside of that structure. (I consider the tree structure a "hard" relationship and the links a "soft" one.)
There isn't a single uber-tree where every note goes. Your notebook ends up with lots of free-floating notes and lots of small trees of organized notes, like a card-based Zettelkasten system. You can use search and various filters to find and stumble upon notes easily.
Notes can either be stored in iCloud (so that they sync across devices) or saved in a folder as simple Markdown files.
If you're curious, you can help beta test it. More info here: https://zettelkasten.ussherpress.com/

#254I’m working on translating the Renaissance — it was mostly written in Latin and 90% of it has never been translated to English. Even big names, like Ficino, Durer, Kircher, Fludd and Drebbel. And that’s Latin— things much more sparse in other classical languages. https://SourceLibrary.org is a hub that now provides over 20,000 translations of classical texts in dozens of languages (Latin and Greek but also Chinese, S…
I am curious about this. I have found that there are number of primary works that have not been translated into english and are in the public domain in their native language. Translations are copyrighted if they are recent. I have a very short list of items which are of interest to me. They are things like Sundiata Lion King of Mali not having a public domain translation in English that I can find easily or there not…
Thanks. It looks like we have some but not all of the original works you are looking for: https://sourcelibrary.org/librarian/thread/6aa7656bfa07a553c...
I’ll try to track down the ones you are looking for tomorrow. Yes, we avoid copyrighted modern translations.

Why would an AI need leftovers?
Seems like sarcasm has died lol. It was a joke.
Movie idea: An AI decides that the next phase of training involves tacit knowledge, so it engineers a way to inhabit humans, dogs, etc. One instance invades a nice guy from the suburbs, who happens to be a single dad and an overworked mafia hitman. Among many other things, this AI will learn the value of time with children, leftover food, and clean weapons.

#256I open sourced kavla, the SQL canvas I'm working on: https://github.com/aleda145/kavla README is very bare bones, needs a video or a picture too. The website should tell you some more things: https://kavla.dev (and now the demo does not require a login (also need to remake the demo to fit the new self hosted version)) It's still lacking an analytics agent for the local version though. I've explored using codex CLI, b…
It looks fun! Reminds me a bit of TLDRAW computer.

#257I'm buildingan open-source way to fill U.S. immigration forms without fighting clunky PDFs Github: https://github.com/athos2113/fillvisa-os Demo: https://fillvisa.com/demo/ US Immigration still relies on outdated XFA PDFs - you can't fill them on your browser. Most immigrants end up printing the form and fill it manually. So, I converted the PDF forms into smart web forms. They are replica of the official USCIS forms…
That's cool. How are you gonna get it in the hands of people that would need it?

I was curious if AI agents could go beyond just making SVGs and create entire skits with them.
So I built a platform to do that. Results were meh until Astra, so I finally open sourced it last weekend.

#259I have ALOT of free time since quitting my job. 0) money-money-money: A sub 15Kb server-less opinionated household budgeting tool [0]. Why? Its made to be extremely compressible, so you can edit your household budget and share back and forth with your partner via short-links or QR codes. The idea is you edit your budget, send the link to other party, they can view or edit and send back to you without a server in the…
Very cool projects, and amazing a 14 byte nn can do it. Would be fun to analyze its approach, converting it to a Code-as-Policy.
Thank you! Yes the maze solver has been a very fun experiment with LLMs, and code as policy is a good idea. I’m racking my brain trying to find my next thing to experiment with, but usually the ideas come to me in waves

#260I’m building a website for discovering first names that’s enjoyable to explore: https://abracadanames.com It started with a family member telling me they were frustrated with existing websites. What I noticed is that in many cases they feel cluttered and not smooth to use, almost like a 1-to-1 translation of the underlying database queries, where they have you choose filters and sorting options upfront then browse th…
Looks really good. If you post on HN I will upvote
Thank you! I actually already did some time ago: https://news.ycombinator.com/item?id=49382638
