Still working on https://phrasing.app - an app for polyglots to learn over 120 languages in the most effective manner and a beautiful UI. Just finished a onboarding flow, now updating the search and create experience to fall more in line with actual usage from users, then hopefully prepping for a more public launch :) Had a fun week fixing up the application so it’s 100x faster on 5 different axes, and it’s starting…

Sounds nice! A word of advice, instead of claiming 120 languages, I feel it would be better to focus on a few an ensure that they work well with native speakers.

You are talking about a very different product :) I have spent over a year making sure everything works for many languages. The whole point is to have one interface, for all my languages, big and small.

Additionally, please try it out before assuming they’re just claims. I’ve been using it daily for 3 months in 18 languages (roughly one from each major language family), and been in pretty constant contact with native speakers.

True I cannot vouche for all 120 languages, and sure there is the occasional error in the lower resource languages. However, I have put in a lot of work to make sure I have a representivie sample, and the errors are currently well within an acceptable range — and I’m working hard to improve them!

I merged support for JavaScript object "shapes" in my Nova JavaScript engine last week; now I just have to clean up some of the ugly parts of the API (and maybe do some performance adjacent changes), and then it's time to use the shapes for property lookup caching!

This is one of the most important performance features in a JS engine, as without shapes property lookups would be terribly slow. I'm looking forward to getting this working.

Working on an web application to turn form fillable PDF's into full interactive TTRPG character sheets, with 3d dice rolling, configurable / re-usable rolls, etc...

Easiest way to explain it is something like D&DBeyond but for indie games.

Optimizing the Marginalia Search index code. The new code is at least twice as fast in benchmarks, but I can't run it in production because it turns out when you do it's four times as slow as what came before it for the queries that are the simplest and fastest to the point where queries exceed their timeout values by a lot. I'm 97% certain this is because the faster code leads to more page thrashing in the mmap-base…

I've been learning PassKeys and WebAuthn.

Getting together a very simple server (PHP), and very simple clients (UIKit and SwiftUI), and will publish a blog series on it (sort of like this[0]), once I get more used to it.

I need to really get comfortable with it before I do that, though.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

This is an interesting idea. One thing that might help targeting is to have some sort of chemical that attracts the mosquitoes. In that way you can bring your target to you.

I run a job board for Germany called Arbeitnow. It runs well without any frequent changes. Recently I've added a couple of new sources for jobs and filtering the kind of jobs that get through (relevant to my audience).

Not planning to do a lot during the promised Berlin summer though

I recently built a site for guessing house prices. I thought I'd be done with it in a week. Over a month later I still have a ton of things to work on. You can at least play some games now though: https://housepriceguess.com/roundup/v/holiday-destinations/p... Enjoy. And yes that really was my wife playing one of the games for the first time in the video ;)

One thing I will be doing this week will be to get different AIs to play the game to get an idea of how good they are. The easiest to start with will be open AI - using the new agent I should be able to record a screencast of it with explanations for each one.
