@mattpocock.com in your capacity as typescript whisperer, have you blogged about "function parameter bivariance"? I'd be curious if you have practical advice how to avoid the problem I describe in this gist gist.github.com/pesterhazy/4...

I could use a nice trip to somewhere in Europe or the UK. I'd like to sponsor my trip by doing useful work with your company. I have a lot of skill and experience in software delivery, code craft, and team management. Consider contracting me for a few days. I would love to help.

Today should a node project use ESM (rather than commonjs) and {"type": "module"}? Just spent half a day fighting with node's module resolution and --experimental-strip-types

Zod v4 is marketed as having 20x fewer instantiations of tsc... While it's great to see progress, this news makes me hesitant to use it. Why was it doing so much in the first place? All that type-level complexity must have a cost

Teamwork makes the dream work… Along with good architecture, agility, frequent communication (“Yes chef!”), domain driven thinking, a ton of collective experience, knowledge sharing and a lot of passion. But 10x developers? Nah. That’s just over-reliance on one point of failure.

I'm, *sigh*, going to get better at llm-assisted development. But I want to treat it as a tool to learn, not a short cut. Where should I start? What are the best guides, preferably from people who understand the limitations as well as the upsides?

Instead of asking “When is all this going to be done?”, consider asking: “Why can't we release what we have now?”.

I was tired of slow #Emacs lsp completions, which locked up my editor for up to 5s. So I switched to lsp-bridge and now I don't know why I didn't try it earlier. It's so fast, so good, I want to scream it from the rooftops!

For the second time, in two very different jobs, I'm encountering unexpected HTTP 502 errors in a backend API. In each case, the symptom is the reverse proxy reporting "Connection closed unexpectedly" or similar. I suspect the problem in each case to be HTTP keep-alive. Is it just me?

And if a test is broken, you have nothing more important to do than figure out why it broke unexpectedly, then make sure the tests & system are in sync and the tests remain predictive & inspiring.

TIL that #JavaScript .getDay() (a better name would be: day of week) returns a different int value for Sunday (-> 0) than ISO 8601 standard (-> 7). Countless bugs must have emanated from this design decision (I'm responsible for a few).

Today, we're making Zero available for the first time in alpha. If you're building a new SaaS web app in 2025 and considering sync, you should try Zero. We're moving quickly toward beta and I think you'll move much faster riding with us than going it alone.

The most annoying problem for Zero's launch was what bug tracker to use. GitHub is way too slow, and Linear doesn't have public bugs or permissions – both required for OSS projects. This was driving me nuts, until I realized the only possible solution… ⏩ bugs.rocicorp.dev/issue/0
