I'm working on a new type of git forge[1], optimized for speed and work with patches.

It goes to extreme lengths to ensure great performance, i.e. rewritten most server-side parts of git from scratch, so there is no "exec"-ing git nor calls to libraries like libgit2. The frontend should also be very fast thanks for HTMX.

I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made…

Wow, neat idea! Is this going to be proprietary or OSS?

Definitely open source!

I’m working on yet another cloud based coding agent https://seniordev.io/ that connects to an existing GitHub repo, spins up a feature branch, commits incremental changes, and opens a PR. You can jump into an embedded VS Code server to review and tweak the code before merging—no local setup needed. Any feedback is greatly appreciated Thanks!

Very much agree that to this is the direction data orchestration platforms should go towards - the basic DAG creation can be straightforward, depending on how you do the authoring - (parsing SQL is always the wrong answer, but is tempting) - but backfills, code updates, etc are when it starts to get spicy.

I think this is where it gets interesting. With partition dependency propagation, backfills are just “hey this range of partitions should exist”. Or, your “wants” partitions are probably still active, and you can just taint the existing partitions. This invalidates the existing partitions, so the wants trigger builds again, and existing consumers don’t see the tainted partitions as live. I think things actually get a lot simpler when you stop trying to reason about those data relationships manually!

Kind of have been wasting time with Cloudflare workers engine. Trying to build a system that schedules these workers for a lightweight alternative to GitHub actions. If you are interested in WASM feel free to reach out. Looking to connect with other developers working on the WASM space.

In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible. Our first dinner was with 13 friend…

That's such a great idea. Especially since you're also helping the restaurants out. Nowhere near that area otherwise I would've petitioned straight away

I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease. https://ovelle.bio

As someone who's dealt with this and know more people, good luck.

You're doing God's work, pun intended.
