More tools / toys / sandboxes to play with.

Growing a coding agent as a "game": https://github.com/dhamidi/smolcode. Started with https://ampcode.com/how-to-build-an-agent and then asked the agent to modify itself. It's so much fun and hard to stop!

Since coding is cheap now, I'm building a web framework for myself, using reasonable defaults: built around the transaction log, single binary deploys, sqlite3 for everything, runtime introspection tools to make ops easier.

I want the framework to "compile itself out of the project", so that projects don't have devtime dependencies and can be easily edited by Cursor et al. It should still stick around in the form of a high-level CLI that an AI agent can leverage to fulfill common tasks (e.g. add a new UI component, query, command, etc).

Myself. Been a freelance dev for years, now going on "sabbatical" (love that word) very shortly. Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things. I'm excited. --- I posted about this on last month's thread, and mentioned in a descendant comment that I was going to PyCon US in May.…

Out of interest, how are you approaching this? Are you trying to "refactor" in specific areas, or is it somewhat more ad-lib? Do you have something in mind for the next "volume"?

I’m building a free, open-source invoice generator with live PDF preview — all browser-based, no sign-in needed.

It supports multiple languages, currencies, European VAT deductions, and more.

Originally made it for myself, so it’s a bit of a personal tool — but I hope others find it useful too :)

Inspired by Steve Brunton(on YT) and his colleague, a platform that makes working on/with dynamical systems much easier in terms of sensing, modeling and controlling the dynamics. Eventually iterating quickly using SOTA techniques(compressed sensing, super-resolution(spatial-temporal tradeoff), RandNLA, ML) without the need to understand them deeply

Sensing effectively by optimal (re)positining of the sensors (both number of sensor and physical placement) Think spatial sensor/data fusion, perhaps using more cheap sensors rather than few expensive

Building a model of the dynamics (based on both reasonable assumption about the system based on grounded physics, and dynamical interpretation of the sensor's data (PySINDy, DMD)

And eventually controlling the dynamics

Love to get your feedback, ideas, if you know about such products/business etc, how could it help any business, real life application, if it interests you, anything :)

For fun over the weekend I started an ambitious project of creating a "pocket size" space trading game, inspired by a classic BBS door game called Trade Wars that I really loved as a kid. I'm keeping a development log to keep myself motivated and wrote the first post about it here https://jarv.org/posts/stardewar-v01/.

An open-source, self-hostable app for sending out newsletter to your friends and families. I'm mostly making it for myself because I want to share what I've been up to and family photos, without uploading it to Facebook or whatnot. At the moment, the flow goes like this: 1. During the week, write posts for things that have happened. 2. Posts can be assigned to groups. (family, friends etc). 3. At the end of the week…

Once I add private blogs/post support to Pagecord, it will kinda do this automatically. Maybe. Sort of. https://pagecord.com .

Pagecord looks really cool. I was once inspired by Bear blog and thought about building something similar but ended up not going forward with it as I didn't think I could guarantee to keep the service up. Best of luck to your endeavor!
