Who needs Git when you have 1M context windows?
Lately I’ve heard a lot of stories of AI accidentally deleting entire codebases or wiping production databases . But in my case it was the other way around. I removed some working code and the LLM helped me to recover it.

Solveit – A course and platform for solving problems with code
You can now sign up for ‘How to Solve It with Code’, which is a course in how to solve problems (including coding, writing, sysadmin, and research) using fast short iterations, and also provides a platform that makes this approach easier and more effective.

The best worst hack that saved our bacon
No-one really likes engineering war stories, but this one's relevant because there's a moral to it. I've talked before about defining technical debt as technical decisions that provide immediate value, but with long-term negative impact if they aren't cleaned up. Sometimes introducing technical debt

Unix philosophy and filesystem access makes Claude Code amazing
Build the advantage your competitors can’t buy2025414 points216 commentsAI & Machine Learning details
If you've talked to me lately about AI, you've almost certainly been subject to a long soliloquy about the wonders of Claude Code. What started as a tool I ran in parallel with other tools to aid coding has turned into my full-fledged agentic operating system, supporting all kinds of workflows.

Diff Algorithms
How I overcame copying and modifying my own diff library from project to project by diving too deep into diff algorithms and coming out at the other end with new diff library in my hand.

Designing agentic loops
Coding agents like Anthropic’s Claude Code and OpenAI’s Codex CLI represent a genuine step change in how useful LLMs can be for producing working code. These agents can now directly …

Software essays that shaped me
I started reading software blogs before I got my first programming job 20 years ago. At this point, I've read thousands of blog posts and essays, but a small handful stuck in my mind and changed the way I think about software.

Comprehension debt: A ticking time bomb of LLM-generated code
Psst. If your boss won’t invest in training you in Specification By Example (BDD, ATDD), I’m running out-of-hours workshops on May 12 and 16 specifically for self-funding learners. £99 + UK VAT. An…

What is “good taste” in software engineering?

Go ahead, write the “stupid” code
When I finished school in 2010 (yep, along time ago now), I wanted to go try and make it as a musician. I figured if punk bands could just learn on the job, I could too. But my mum insisted that I needed to do something, just in case. So I went down to the local TAFE (this is like a trade school in Australia, though…
