Six months of writing, rewriting, and occasionally questioning everything I thought I knew about AI-assisted software engineering.
The result is The Second Time Is a Bug, a practical field workbook on building reliable systems around AI coding agents.
34 patterns. 26 reproducible drills. One central idea: the first mistake may be the model's, but the second deserves an engineering response.
Publishing soon.

if "don’t touch the tests" actually matters, it shouldn’t live in CLAUDE[.md]..
a PreToolUse hook that rejects writes under "tests" is like 10 lines and the agent can’t talk its way past it

trying something new... writing a book in public for the first time
it's called "the someday folder"... for anyone with a folder full of half-finished side projects, now that AI can help build almost anything.. why hold back?
first chapters go up next week, new ones every 1-2 l free while i’m writing it

Harness Engineering. That's what most of the book is about. Increasing reliability of your coding agents..

it's on leanpub, hit "notify me" and you'll get the first chapters next week: leanpub.com/thesomedayfold…
tell me where you stop reading... that's the feedback i want most :)

if you want to know whether your AI/SI reviewer actually catches stuff... plant a bug you already know about and open the PR
off by one, a missing await, a test that asserts nothing
if it says "looks good, minor nits" that’s your answer

I watched How to Live on Earth for Benedict Cumberbatch's narration. Stayed for the message.
It resonated enough that I ended up building an interactive website inspired by it.. 🌍
A little passion project about learning to live wisely on this planet.

lots of sites blocked GPTBot back in 2023 and moved on..
GPTBot is OpenAI's training crawler.
OAI-SearchBot is the one that decides if you can show up in ChatGPT search.
separate lines in robots.txt
worth checking which one you actually blocked

Every time someone says "ai can't write good code", I know that they can't write good code.

I'm creating this post only so that I can boost this post. Sorry. That's just how X works.
I released a new book... if you find the sample chapter useful.. please buy.. :)

There's a particular kind of unfinished project that keeps coming back.
You stopped working on it months ago. Then you come across something that reminds you of it. A new tool appears. Someone mentions the problem you were trying to solve.
You think: I should get back to that.
few minutes.
The project might be a half-built app, a document full of notes, or an idea you've explained to three friends. It still feels possible. You just haven't decided what to do with it.
Collect enough of these and you have what I think of as "the someday folder".
It doesn't have to be an actual folder. Some of it lives in browser tabs. Some in old repositories. Some entirely in your head.
The difficult part is deciding which ideas still deserve your time.
Try opening one this week and writing down what would make it worth returning to. What would you need to find out?
That might give you a smaller, more useful next step than "finish the project".

At this point, building your own version control system, CI/CD pipeline, and deployment stack almost feels as secure as relying on the established ecosystem.
With the growing number of attacks targeting open-source software and software supply chains, the trust we've placed in our development infrastructure deserves some serious scrutiny.
And somehow, "just shut everything down until we figure this out" is starting to sound less like a joke.

Nobody:
Absolutely nobody:
Tech folks on X: "Name one technology that does [something] better than [insert my favourite technology here]. I'll wait."
The engagement-bait template that apparently never goes out of fashion... 😂

every time my coding agent makes the same mistake twice, it goes through one loop now. walking through it with a real one from a small site I run..

prove it works. put the mistake back on purpose and check the control catches it. if you never saw it fail you don't really know it works
