After years of using ORMs, my latest project is using raw SQL. I've written SQL before, but never for stuff quite as complex as this and, I have to say, I think I finally understand JOINs. 😂

After 10 years of moderating r/lfg, we’ve learned that finding a game isn’t the hard part. Finding the right game is. That’s why we’re building RollTogether: structured listings that make it easy to find games that fit your system and schedule. Follow for updates. #TTRPG #LFG #RPG

Writing a backend in #golang after coming from #django / #python is quite a shift. On one hand, there’s a ton I can (and am recommended to) do with just the standard library. On the other hand, testing requires a lot more boilerplate. Learning how to do that and be DRY is a challenge.

As someone who normally lives in the backend, I’m enjoying @svelte.dev quite a bit, especially the way routing works. 🙌

Ford has rehired hundreds of senior engineers after replacing them with AI backfired and has cost the company billions of dollars. AI adoption is blamed for Ford being the most recalled automaker in the U.S. with 51 recalls covering over 11 million vehicles in the first half of 2026 alone.

I'm currently #coding a #mud and am thinking about secret doors. I want both the kind that can be found by manipulating the environment ("pull sconce" or "push bookshelf") but also the ones like a passage hidden behind a waterfall. Supporting both will be a fun challenge. #indiegames #oldschoolgames

Had an idea for a kinda simple web app to help with something I wanted to do the other day. No auth needed. Landing page, creation page, and view page. Hardest part would be some CSS animations. Going to try to get it implemented this weekend. Stay tuned. #flask #python

Read a post where an #sre discovered a recent incident had the same root cause as an earlier incident. Someone chimed in that they didn't have the same root cause: the root cause of the second incident was not prioritizing the fix from the first incident. #postmortem items need due dates!

I've been playing with Java over the past week. After years of semi-colonless languages, it feels a little strange, but there are parts of it I am really enjoying. Having a solid IDE which reminds me of features which I've forgotten--or which have been introduced between Java 8 and now--is nice.

One of my favorite ways to learn a new framework is to follow a tutorial for another language or version and try to make it work. When I was learning Django 2.x, I followed a tutorial for 1.x and became VERY familiar with the docs. Now, I’m following a C# microservices course, but writing it in Go.

Quickly burned through the Grafana Cloud free tier, so decided to stand up my own LGTM stack. Ended up trying out VictoriaMetrics and VictoriaLogs instead of Mimir and Loki. Not quite as good of an integration with Grafana, but amazing performance which is killer for a scrappy side project.

One of my favorite practices in MR review is emoji-based. - When someone requests review in Slack, react with 👀 once you start looking at it. - If you find something needing changes or discussion, react with 💭. - When you approve it, react with ✅. And, of course, thank the reviewer with a :ty:
