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 well.

Writing my own (concise, simple) programming language was a dream for me since I'm 20 or so. Feedback would be great!

Tanstack DB - a new client side store for web apps, with transactions, optimistic state, and live queries spanning multiple collections. It's designed for sync, so rather than fetching you can hook it up to a sync engine (any!) to keep your front end in sync with your backend. It's built on Tanstack Query, making the sync engine optional, and a great path for incremental adoption. The query engine uses a typescript i…

Very excited for this. Current client-side DB implementations are hard to work with. Will it support IndexedDB?

We are building a social network that makes it simple for people all over Africa (Niger) to find, organize, and share events, such as underground music performances, street festivals, local markets, and cultural gatherings. We are creating something that is accessible to all, supports grassroots communities, and honors local culture.

This platform is entirely self-funded and was created with passion, hard work, and faith in our goal. However, at this point, even modest assistance, such as paying for our internet, can have a significant impact on future advancement.

Find me on LinkedIn if this speaks to you or if you would like to work with me, grow together, or just have a conversation. Connecting would be wonderful.

One community at a time, we can work together to illuminate Africa's events landscape.

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…

There's an awful lot of complex navigation, signal processing and trigonometry required here, good luck.

What's the fidelity of the sonar in detection of flying mosquitoes?

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…

This is basically what everyone that tries to use mmap in their database realizes.

I have been unemployed for the last few months, and there's only so much TV and YouTube I can watch without going utterly insane between interviews, Since WGU just started doing masters degrees in CS, I decided it would be a way to kill large amounts of time while getting at least a little out of it, so I registered for it. I've been a professional software person for like fourteen years, so I was able to knock it ou…

Best of luck on your job search, hope you land something soon!

I am finishing mobile UI for Gethly(sales and hosting platform for digital content creators - paywalled content hosting). It is taking a bit longer than I wanted but it will be done soon. But I am looking forward to August because I will be implementing a new feature - Paywall As A Service, which will allow content creators signed up with Gethly to host their content remotely and Gethly will manage finances and content access. Due to the way Gethly is set up, it supports micropayments, so people can charge merely 1 cent for access, which should satisfy both - creators and consumers. It is a feature I am really excited to work on and I expect it to take no more than two weeks to implement and deploy.
