Using AI to write code has made me realize there are two types of code I've traditionally written: 1. Code that I want to know how it works 2. Code that I want to exist but don't care how it works I delegated 100% of the second category to AI now. Maybe 50% of the first.
I revisited this yesterday, wrote a more barebones version ("three regexes in a trench coat") and turns out it works almost as well, faster, and with a very simple codebase. Garbell: skill and tooling for simple codebase exploration via progressive disclosure github.com/rberenguel/g...

Ruben Berenguel@berenguel.bsky.social · 7mo agoI wanted to play around the RLM idea, but I really, really disliked the concept of having the context in Python variables. Instead of that (or my first idea of "put it in a sqlite db and make the agent write sql"), I wrote tooling to use as skills over a running daemon github.com/rberenguel/c...

New (to me) coding agent use case: shrinking bug repros involving huge queries. Essentially: "this query reproduces a bug: please binary search to shrink it."
In 2025, I "shipped" 60 personal projects. The breakdown: 28 games, 16 creative tools, 11 Obsidian plugins, and 5 Chrome extensions, most of them things I use weekly if not daily. I did not expect how mentally taxing managing "an AI coding factory" would be, though. mostlymaths.net/2026/01/2025...
Supervising the Idea Factory: My Year of 60 Personal Projects
In 2024 I leaned on LLMs to get several personal projects done (around 20). This year I took that to 11 (60 projects).

We’ve pushed out the Pareto frontier of efficiency vs. intelligence again. With Gemini 3 Flash ⚡️, we are seeing reasoning capabilities previously reserved for our largest models. This opens up entirely new categories of near real-time applications that require complex thought. More in thread ⬇️

Simon Späti 🏔️@ssp.sh · last yr.How do you manage your todo's? Here's a brain dump of how I manage my todo's, personal and business. Usually it's not about the tool, but the constraints, and the clear rigidness, to not add more work to your plate than needed.

Yesterday I got to 180 solutions manually found (3/4 done), had an idea, convinced Gemini to code it... and now I guess I'll have to write a blog post explaining it, sigh

Ruben Berenguel@berenguel.bsky.social · last yr.177 / 240 I won't update the very long list of images thread, it's a pain in the ass. If I ever finish, I'll post them somewhere, although there is a bug in my colouring and sometimes the chiral pieces have swapped colors (it shows in some of the solutions here)
Q: My condolences on the loss of your friend Charlie Kirk. How are you holding up? TRUMP: I think very good. And by the way, right there you see all the trucks. They just started construction of the new ballroom for the White House, which is something they've been trying to get for about 150 years.
