Working on https://openreaders.com – a platform with free graded readers, starting with Spanish (my native language).

When learning a new language, it’s surprisingly hard to find free, engaging reading content at your level. Even paid options often aren’t that great. I’m trying to solve this by leveraging LLMs, building useful features for learners, and focusing on user experience.

Just launched the beta yesterday on Reddit: https://www.reddit.com/r/dreamingspanish/comments/1matsp6/fr...

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…

I guess you already researched this topic: would laser turret work for killing mosquitos? And if no, why not? Seems more reliable.

I just discovered the formulas Excel library for Python, and I have about two dozen ideas for things that you could do with it. It turns out they already implemented the first dozen in the library itself, but the possibilities that come from extracting the computational graph out of a workbook are huge.

What ideas haven't been implemented that you're going to work on?

At the top of my list is taking unstructured workbooks and adding a sheet to tabulate inputs and outputs. A lot of spreadsheet models are not set up for bulk evaluation or retaining old results, and the peculiar arrangement of cells constitutes an ad hoc user interface for the model. I want to take that seriously as a programming environment for subject matter experts and give them an extra tool for working with their models. As programmers, we give spreadsheet authors far too little credit for intelligence and skill, and often blame them for the faults of their platform. This is unproductive, and we can do better.

I'm trying to get the word out that: The judges are the top lawyers and the lawyers are pieces of shit.

The US domestic (family) court system, in Ohio in particular, has become functionally corrupt.

The Ohio bar association has co-opted the domestic court system for their own revenue generating stream. The judges profit from kickbacks in the form of campaign contributions every four years from the very attorneys are supposed to be judging against, this is not just the appearance of corruption it is a system built on it.

On top of that, all the judgments are sealed and secret, meaning that there's zero records and zero accountability for any judges or lawyers in the system. This means the judges only incentive is to judge in a way that is most in line with his best interest. In practice this means that what little data we have shows that almost every time the judge finds in favor of whichever attorney donated the most money to his campaign.

This has been going on for the better part of 20 years and is the reason that 85% of divorces end with single parent custody in Ohio, it's because the judges are getting paid off.

I'm blowing the whistle, working on websites, printing signs, sending out mailers, Court watching and taking notes on these corrupt evil fucks, doing anything and everything I can to get the word out that the Franklin County Ohio domestic court system in particularly has been corrupted by a small group of judges, mainly Judge James Brown. I'm doing everything I can to get the word out about these evil and corrupt judges, the biggest hurdle seems to be how much money they are making and that people believe that once a lawyer gets rich and powerful enough they're uncorruptible, which is the exact opposite of the truth. The judges are the ones running a corrupt, pay to play, system of kickbacks with themselves at the top. The judges are the top lawyers and the lawyers are pieces of shit.

They are literally horse trading children like they're chips at the casino and what they've done to a generation of young people and millennial fathers is pure evil.

I'm working on a new memory-safe systems programming language that is supposted to be (almost) as fast as C, Rust etc, but as simple and concise as Python: https://github.com/thomasmueller/bau-lang There is a playground which is using a C compiler and WASM, and so is quite fast, while running fully in the browser. Theres also a (online) conversion tool to convert and compare source code. There are some benchmarks as…

I like the idea of compile-time asserting that no runtime check is needed for array access!

Thanks! I know Rust, Java etc do a good job of array bound check elimination, but I prefer a way to _ensure_ there is no check. I felt this was missing.

We're working on brief.audio, looking at taking the concept of personal podcasts (sort of introduced by NotebookLM) into its natural conclusion by thinking more about what content should be included and how to tailor the outputs into something that is really nice to listen to. Make it a truly slick mobile experience.

https://www.brief.audio -> Have a go, we're primarily testing internally atm, will look to make it more available and a bit more polished next week.

Primary focus is getting the content right this week with the audio script and hosts being user & content dependent. :)

Especially interested in hearing what content to pipe in (we're looking to put in our hackernews.coffee as a feed for example, but also other key news sources).

why spend the scarce energy of the battery in addition what's already being spent spinning the propellers

I'm working on pact[0], a tool to enable developers and hopefully less technical users to interact with Playwright and perform actions and tests on web-based user interfaces and applications using either a YAML file or a simple DSL (in a .pact file). Initially this started off as a feature for a PR on venom[1], an integration testing tool, but as I thought about it more - it made sense to maybe make a standalone tool…

Might be worth considering a different name before you get too big. There's already pact.io, which will be the first result any time anyone searches for pact testing.

Thanks for the heads up! I don't know how i missed pact.io - interesting that both are about testing. Will try to think of a different name :_)

Unfortunately it won’t. an eye that collimates light is much more fragile to laser than a mosquito.
