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...

Block was a really great place to work for the past four months. Unfortunately, I’m part of today’s 40% layoff.
If you need an old hand at web stuff, who has staff software engineering experience at multiple international corporations, hit me up. ❤️

Getting laid off sucks, but I just realized that I have never taken more than 2 weeks off between jobs before, and I’ve always juggled interviews with actually working. So, silver lining, I’ll get a nice long break for the first time ever, and I’ll be able to focus on studying for interviews

That’s the biggest bummer for me, I truly loved working at Square! I loved the amazing people, I was doing really good work, getting great perf reviews. Sadly I guess that isn’t enough these days. Time to join you in retirement maybe

I lucked out that I was able to scavenge amongst my son’s collection for the whole thing, so there are some wacky colors under the surface

THIS THIS THIS THIS THIS. not just in communities, but companies too. I have never in my long career worked with anyone who deliberately *made the choice* to be a “low performer” without curiosity/discipline/agency, it’s always been beaten out of them

Redefining the Software Engineering Profession for AI | Communications of the ACM
Props to @scott.hanselman.com for naming the elephant in the room in big tech.
AI coding tools boost senior engineers but create challenges for juniors who lack context to judge outputs. Cutting junior hiring for near-term gains weakens the future pipeline. We’ll need apprenticeship-style paths.

Accessibility: Yellow, Purple and the Myth of “Accessibility Limits Color Palettes”
I won't have time to debunk the old "yellow is not accessible" myth in my axe-con talk.
But, you are lucky: I already wrote a whole article on how accessibility does NOT limit color choices.

testing, one two - Chris Dickinson
testing
Arguing about unit tests vs. integration tests sucks. It's dogma and I feel like a heretic.
This post discusses a different way to think about a test’s scope. I love it.

JS-heavy approaches are not compatible with long-term performance goals
I’m Sérgio, and I work with Web frontend code. Sometimes I write about it here.
It's been a while since my last blog post, so I made up for it with a wall of text 😅
This article looks at why JS-heavy web apps tend to miss their performance goals over time, what you can do to somewhat mitigate that, and ends with a plea for us to move back to the server, as an industry.

They're Coming for Our Daughters
The conservative plan to shrink girls’ futures
The Heritage Foundation has released a 250-year roadmap to “save America.”
The document is a how-to guide for subjugating girls & young women: a detailed plan to push them out of college, funnel them into early marriage and motherhood, and then trap them there.
