What garbage collection actually costs · Shivanshu Agrawal
Why the cost of a GC cycle is about objects and references, not bytes — and what to measure before you try to optimize it.
Two days on Opus 4.8, then 34 hours on Fable 5. Same research problem, same hardware, one model generation apart. I wanted to know what the bigger model actually fixed and whether the answer supports Anthropic’s recursive-self-improvement story. I ran these ex…
A small always-on server, dark to the internet, that keeps an Obsidian vault converging and version-controlled, hosts coding agent sessions I can drive from a phone, and — unplanned — reaches my tasks, mail, and calendar.
An interconnected-knowledge thesis: what it means for scientific breakthroughs, potential safety risks, and continual learning.
I started the same side project three times in two years. Two attempts died the same way, and it took me until the third to understand what that way was.
Three Ways to Sell the Same Software
A look at how subscription, usage and outcome pricing divide the surplus, shift performance risk, and change what a vendor is on the hook for.
Every few weeks, someone declares that coding is solved. If they mean turning a well-specified problem into runnable code, they're increasingly right. But was writing runnable code ever the whole problem?

LLMs can code, should they? OpenAI released ChatGPT on November 30, 2022. I’m writing this article in June 2026. Software engineering is different from what it was before 2022. What has happened? LLM models got larger and programs were written to make it possi…
Designing with code
Code has always felt like a natural creative medium to me. Maybe it’s that I went to school for engineering, not art or design. 0:00 /0:03 1× When an idea is defined by a set of rules, you can generate endless va…
Rails is done
The core of Rails has stood the tests of time. To this day, it is a great way to build web applications. But DHH’s view of the world is fundamentally incompatible with mine, and I’m not the only one who feels that way. About a year ago, a bunch of people, incl…
LLMs are used for any things. Learning new things is one of the top use cases.
Many tools on one WGSL core
A database write can stop after memory, a local SSD, an object PUT, or a replicated WAL. Each choice changes latency, durability, and who owns the work left for later.

Advanced AI sycophancy
Everyone knows that AI sycophancy is when the model tells you how smart you are. Wow, you’re absolutely right. That’s not just a new idea — it’s genuinely groundbreaking. You’re a very special user. Easy to spot, isn’t it?
