Advocating the use of appropriate AI and data standards for fighting financial crime: https://soteria-initiative.org/

Financial institutions and governments don’t spot crime because of incomplete information at individual firms. We help them understand federated learning and how to effectively collaborate and not just talk about it. All code is open source, so you can always help out ;-)

Some industry players are coming around: https://www.swift.com/news-events/press-releases/swift-ai-in...

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…

That’s so great, good luck with your project!

Currently working on an open-source agent for privilege access management (PAM) and just-in-time access (JIT) to cloud infrastructure, SaaS applications and local systems. It's using serverless workflows (https://serverlessworkflow.io/) and https://www.temporal.io to guarantee robust deterministic workflow execution. Temporal is used to orchestrate elevations across environments and systems. It tasks “agents” to grant access where it needs to be rather than centralising permission stores. It guarantees execution and revocation of permissions. Run it locally for sudo, UAC. Or in the cloud for IAM or for individual applications. Check it out: https://github.com/thand-io/agent

Currently working on my resume website to make it easier to get a sense of what type of developer I am: https://www.terwiel.io/ Also working on a GxP-compliant, offline-first, real -time synced QMS, but I’ve put that on hold in favor of optimizing my resume.

Your resume web is awesome! Congrats!

I am wrapping up https://github.com/zby/DayDreamingDayDreaming - it is a project to show that https://gwern.net/ai-daydreaming can work.

It is hard to show that AI can reimplement for example special relativity - because we don't even have enough text from 19th century to train an LLM on it - so we need a new idea something that was invented after an LLM was trained. I took the Gwern's essay and checked with deep search and deep research which ideas from that essay are truly novel and apparently there are some so reinventing them seemed like a good target: https://github.com/zby/DayDreamingDayDreaming/blob/main/repo... https://github.com/zby/DayDreamingDayDreaming/blob/main/repo...

So here it is - a system that can reliably churn essays on daydreaming AIs. On one level it is kind of silly - we already knew that infinite monkeys could write Shakespeare works. The generator was always theoretically possible, the hard part is the verifier. But still - the search space in my system is much smaller than the search space of all possible letter sequences - so at least I can show that the system is a little more practical.

Here are some results: https://github.com/zby/DayDreamingDayDreaming/tree/main/data...

You can modify it to reinvent any other new idea - you just need to provide it the inspirations and evals for checking the generated essays.

I am thinking about next steps - maybe I could do it a little bit more universal - but it seems that to build something that would work as needed would require scale.

I kind of like the software framework I vibe coded for this. It lets you easily build uniform samples where you can legitimately do all kinds of comparisons. But I am not so sure about using Dagster as the base for the system.

I am working on the little book of algorithms: https://github.com/little-book-of/algorithms A project to implement 1000 algorithms. I have finished around 400 so far and I am now focusing on adding test cases, writing implementations in Python and C, and creating formal proofs in Lean. It has been a fun way to dive deeper into how algorithms work and to see the differences between practical coding and formal reasonin…

Great idea. I had been thinking about pretty much the same but perhaps targeted at executives and perhaps including AI/Cloud.

I usually feel to many people wildly through around terms they hardly understand, in the belief they cannot possibly understand. That’s so wrong, every executive should understand some of what determines button line. It’s not like people skip economics because it’s hard.

Would love to perhaps contribute sometime next year. Stared and until then good luck - perhaps add a donation link!

I'm still working on the Mint programming language ( https://mint-lang.com/ ) and DevBox ( https://www.dev-box.app/ ) which is a desktop application/browser extension/web application with a bunch of small tools.

I have been following Mint for a while and it feels like a project that truly focuses on making developers happy. The mix of Elm style structure, strong typing, and builtin tools like testing and formatting makes it really enjoyable to use. Keep up your great works!

Thank you!

Working away at https://TempMailDetector.com , a privacy focused disposable email detection API which only requires the domain part and not the user part of the email. The service is able to determine if a domain is likely a disposable email, a forwarding service, and actively crawls for new domains.

> privacy focused

You're hurting people who are using disposable email addresses because they are privacy focused though.

Currently a one-man side project: https://laboratory.love Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard. That seemed solvable. Laboratory.love lets you crowdfund independent lab testing of the specific p…

On https://laboratory.love/faq you say: "We never accept funding from companies whose products we might test. All our funding comes from individual contributors." On https://laboratory.love/blog you say: "If you're a product manufacturer interested in having your product tested, we welcome your participation in funding."

Bit confused as to your position on funding.
