(Pyrefly dev here) As another commenter mentioned, Pyrefly is still in alpha. Sorry we don't make that more clear! While we are in alpha, and there are plenty of open issues we are…

(Pyrefly dev here) Thanks for trying it out! If you have any feedback or bug reports, please don't hesitate to file issues on GitHub or find us on Discord. We have some open issues…

Thanks for trying it out! If you run into any blockers, please let us know by filing a GitHub issue or sending us a message on Discord. Pyrefly is still alpha software, so bugs are…

Hack is quite a bit more optimized than Pyre was, but Pyrefly is at least 10x faster than Pyre on the IG codebase. I didn’t know about the Rust-based Hack checker— that’s really co…

Hey Kevin, we overlapped for a bit during your time at FB when I was working on Flow. Nice to hear from you! I’m working on Pyrefly now, but worked on Flow for many years before. F…

I don't think that's what was meant, but rather that ocamlbuild sucks. It's not the best.

I think the calculus changes when you consider teams with 1000s of programmers committing 100s of changes per day. Keeping feature branches up-to-date can pretty quickly adds up to…

I haven't taken many online courses, but here are my favorites (notice a trend): Andrew Ng's ML Class - This makes the list because it is incredibly useful. I didn't have much back…

The link you provided doesn't seem to show disjoint union support. I'm talking about this: http://flowtype.org/blog/2015/07/03/Disjoint-Unions.html

While the type annotation syntax between Flow and Typescript are mostly identical (this is intentional), there are a bunch of differences between them: * TypeScript allows unsound …

One particularly relevant feature of Flow is that it does its type checking in a server. It watches the file system and incrementally rechecks automatically when files change. With…

My approach to tight budgets is simple. There are just two rules: 1. Get to something that works ASAP 2. Always work on the most important thing Once you have something that works,…

This is bound to be a controversial opinion, but I fall down strongly on the side of time and materials billing, as opposed to fixed budget (FB). I don't hold this opinion as a way…

I have quite a lot of experience using migrations in Rails, and over time I've become just incredibly suspicious of "down migrations." I have never once been in a situation where I…

I really admire Netflix's ability to put together developer documentation for their open source projects. I think it reflects well on their engineering culture. I was similarly imp…

I've been really interested in this architecture since Jay Kreps' blog post on it. One part that I'm less clear on is how this fits in with request-response style communication bet…

Basho has experienced some MAJOR brain drain in the last year. I wonder if this re-positioning is related to that.

For sure, tooling is an area that will get better over time. I am quite happy with the very simple vim-flow, but TypeScript's tooling and overall ecosystem (tsd/definitelytyped) is…

TypeScript is great, but you might look again at flow. ES6 features are being added (I'm adding let/const support) and many already exist. Import/export (incl. types) are in, fat a…
