My newsletter's 9th anniversary is this weekend! Every year I offer raffle prizes and giveaways for readers. If you or your organization would like a "free" ad and offer some prizes/credits/swag, let me know! There's some really fun ones this year already, can't wait to see y'all in your inboxes.

You can now create GitHub Issues directly from Slack in natural language! Mention @GitHub in any channel and describe your work, and the app creates structured Issues in your repo (and sub-issues, too).

i don't need another mechanical keyboard or writing tool, but dang if @cassidoo.co doesn't make me want one! cassidoo.co/post/the-byok/

I've been working on my app, todometer, for nearly a decade, and took a journey down memory lane to see how the styling of the app changed over time, ultimately leading to native CSS today! cassidoo.co/post/css-tod...

Why am I only discovering @cassidoo.co s newsletter now?? 🙂

Parents of babies and toddlers FYI: The backup outfit is too small

I have a new camera setup, and I blogged about it! I've already had to refer to my own blog twice today so... mission accomplished. cassidoo.co/post/set-up-...

I am devastated

I just love surfing the web

Added some updated referral links recently to my bucket if you want some free credits (...while helping a sister out) to services like Zo Computer, Ente, Tally, Kinetic Labs, and mooore: cass.run/ref

Phil is one of my fave coworkers I've ever had and he's also incredibly British

Yesterday was my last day at Deno. From today, I'll be cheering the talented team on from outside the org. This also means that I'm now considering my next move in the DX/DevRel/Technical marketing space.

This is was intense. Seeing that bowl cut would strike fear into the heart of any CSS dev but @cassidoo.co came out swinging! What a fight!

This was perhaps the most stressful programming I've ever done, I had a BLAST competing with @joshwcomeau.com and y'all should watch me panic-sing

I can't get over how amazing this series is. Production value is off the charts! Today’s episode is the right side of the bracket. I faced @cassidoo.co and our match was settled by the closest margin in the entire bracket. 😂

Kinetic Labs just restocked my keycap design, PBT Jeju, if you're looking for a set for your latest keyboard! kineticlabs.com/keycaps/kine...

So I want to talk about AI more (or really engineering practices in an AI era). But every time I spend any reasonable time thinking about it, well, let's just say I crash out

Watched March MadCSS and thought "what if we could do this every day?" So I built it. In a day. cssdaily.dev — a daily CSS challenge. Write CSS to match a target, get pixel-diffed in real-time. New challenge every morning. Scoring adapted from @wesbos.com and @tolin.ski's open-source SynHax.

The latest episode of The Download is out! www.youtube.com/watch?v=1iG8...

I was showing devs how to run coding agents on my work livestream yesterday and asked the chat, "what do you do while your agents are running?" while I wanted for mine to run, and grand majority of the responses were just "this" lol

tech CEO in 2026: My computer has anxiety. venture capitalist in 2026: Here, have 200 billion more dollars. child in 2006: My NeoPet is angry at me. mom in 2006: No it isn't sweetie, go to bed. mom to dad in 2006: We have an idiot boy. Our boy is a little idiot person. It's too late to fix him.

I had no idea what I was getting myself into, but damn you're in for a treat. Build a Bracket before tomorrow, March 6th for the chance to win awesome prizes at madcss.com!

Issue Forms just got better! You can now let people upload files as they open an issue.
