Anti-patterns: things to avoid - Agentic Engineering Patterns
I started a new chapter of my Agentic Engineering Patternw guide about anti-patterns - things NOT to do
So far I only have one: Inflicting unreviewed code on collaborators, aka dumping a thousand line PR without even making sure it works first simonwillison.net/guides/agent...

Vera โ A language designed for machines to write
A programming language where verification is a first-class citizen. Mandatory contracts, algebraic effects, typed slot references, compiles to WebAssembly.
I built a programming language you're not supposed to read, veralang.dev. Vera is designed for machines to write. No variable names. No style choices. Compiler errors are instructions for the model, not diagnostics for you. Go and point a model at it, negroniventurestudios.com/2026/02/28/a....

I was suggesting earlier that they might have been inspired by Douglas Adams and the Disaster Area stunt ship.

Button bar screen shot from my iPad. There are a bunch of buttons on the right hand side, but they're black, on a black background ๐คฆ๐ผโโ๏ธ
Did the liquid glass people at Apple take their inspiration from Douglas Adams and the Disaster Area stunt ship?
โEvery time you try to operate one of these weird black controls that are labelled in black on a black background, a little black light lights up black to let you know youโve done it.โ

I remember my dad explaining bakelite to me as โthis is what people had before proper plasticโ. It had been around for decades before he was born in the late 30s.

When the Right Wing squeaks in, it's a mandate and a true cultural shift. When the Left wins it's an aberration that we need not pay attention to.

"Just as there are clouds and clowns, there are hyperscalers and mere scalers of hype. Amazonโs and Microsoftโs incremental CAPEX in 2025 is each roughly on par with hype scaler Oracleโs lifetime CAPEX."

Nobody knows what programming will look like in two years
Kent Beck doesn't know what programming will look like in two years, and he's been thinking about this longer than most of us.
Kent Beck at @yowconf.bsky.social Sydney: nobody knows what programming will look like in two years โ "even getting to 'it depends' would be progress."
If you're feeling anxious or grief-stricken about where our industry is heading, I wrote this for you.

Itโs kind of weird that itโs taken so long for this stuff to become mainstream.
Acunu did a flash friendly filesystem that helped make Cassandra performance more consistent, leading to an Apple acquisition in 2013 :0

Which doesn't indicate that coding agents aren't useful.
They obviously are super useful.
My read is that it indicates the obvious fact that software development velocity is dominated by factors other than the writing of code itself.

Cognitive Helmets for the AI Bicycle: Part 1
I hear people name these three fears: will developers lose their problem-solving skills, learning opportunities, and critical thinking? One science-backed area can help: better metacognitive strategie...
So many developers have sent me that Anthropic skills/mastery case study that I realized I should ungate what I *already wrote* about this: beginning principles to design workflows that work *with* your mind, not against it, & protect your problem-solving

If I was starting out again today I'd find a nice Hugo theme to publish to GitHub pages (and I have various projects that aren't my main blog where that's exactly what I've done).
Even if you decide in the future that GitHub isn't a safe home, the generated pages are entirely portable elsewhere.

GitHub Community Insights is now hidden behind a mandatory setup of discussions.
What fresh hell is this?
I'm guessing the GitHub PM for Discussions has a number to make, and the only way to do that is dark patterns ๐คฆโโ๏ธ

AI slop is ripping up the social contract between maintainers and contributors essential to open source development. Practitioners have been repeatedly assured that AI would supercharge their communities, but so far that hasnโt been the case.
