Re:Launch HN: Issen (YC F24) – Personal AI language tutor

Portuguese should have the flag of Brazil.
Don’t dim screen on iPhone during conversation.
The tutor should terminate the lesson when its goals are achieved and do a warm handoff.
Overall it’s quite good.

Same way to write self referential structs - use index types into the whatever arena you are using. Indexes are usually 32 bit so they are a bit faster than pointers.
If you are building one off trees such as for parsing and ast transforms, bumpalo is your friend.
In your case, you can look into generational arenas and slabs which are useful for graphs.

Continuous profiling for Linux. It uses ebpf to sample running programs and unwinds the stack, then uploads to server so you know why it look 10 seconds to process that customer’s request last Christmas. :)
Currently supports x86-64 and ARM64

This still makes no sense at all. Self hosting means running a program on your own machine instead of on a cloud platform such as cloudfalre.

Have you tried DuckDB? It’s the columnar version of SQLite.

DuckDB is also great for stuff like this. You can replace a MapReduce cluster with a single SQL.

RawStr Notes solved a personal pain point with all the cloud-based notebook currently. Hopefully this could be of use to other software developers. Please let me know what you think. Thanks!
Show HN: RawStr Notes – The missing notebook for developers
Hi HN,I built RawStr Notes(https://rawstr.com/) as a replacement for Google Keep, Apple Notes, Evernote, etc.. It's an executable notebook based on VSCode's Monaco editor where everything can be scripted.1. My typical workflow is copying text out of $NOTE_TAKING_APP to VS Code(for Vim) and back. RawStr saves the roundtrip by integrating VSCode's Monaco editor in the browser.2. I save a list of...

You are correct. It is indeed possible to use dynamic programming. For more info check out [0]. OP’s project probably takes too long on nontrivial merges in its current state.

I agree with the article you linked.
Mathematical knowledge is about compression. Most if not all of these formulae are just specializations of known formulae. So the value of this approach is questionable. Generating these forms can possibly be done in a much simpler way.
