I am looking for a full-time job.
Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.
If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

tsgo is not just faster than the original @typescriptlang.org compiler. It’s also *more correct* in a bunch of places. There might still be bugs where it’s less correct, too, but that’s not what I’m finding in general working on Vanta’s codebase! It’s just real bugs. 😂 😭

We are still looking for feedback on tsgo, but it is worth calling out we expect some type-checking changes that you may need to adapt to.

really bummed that github.com/golang/go/is... was closed, sucks to get a fuzzing failure that cannot be fixed and then just, not be able to fuzz any further
cmd/go: -keepfuzzing needs renaming, does not exist · Issue #48127 · golang/go
Generally, we try to keep the flag names big-endian, so that related flags all have a common prefix, like bench, benchtime, benchmem; memprofile, memprofilerate; even fuzz, fuzzcachedir, fuzzminimi...

Email them about a bug in my Element 3 amp (randomly crashes), the CEO himself sends me firmware to try out, then when that doesn't work they 2 day air advance exchange me a new Element 4 (newer model!) at no cost to me.
