Development environment with Nix Flakes and Direnv

This document is targeted at those who seek to build reproducible dev environment across machines, OS, and time.

It maybe easier for remote teams to work together and not spending hours each person setting up asdf/pyenv/rbenv, LSP servers, linters, runtime/libs. Nix is probably the closest thing to Docker in terms of development environment.

Flake is used here because it provides hermetic build, with absolutely no reliance on system environment (be it Arch/Catalina/Mojave). Also it freezes dependencies in flake.lock so builds are reproducible.

This gist provides the setup to develop Java/Clojure/Python applications on Nix. But it can be easily adapted to ruby, nodejs, haskell.

I have found this interesting for debugging, but also fun to hear web pages

• any: magic, ill-behaved type that acts like a combination of never (the proper [bottom type]) and unknown (the proper [top type])
  • Anything except never is assignable to any, and any is assignable to anything at all.
  • Identities: any & AnyTypeExpression = any, any | AnyTypeExpression = any
  • Key TypeScript feature that allows for [gradual typing].
• unknown: proper, well-behaved [top type]
  • Anything at all is assignable to unknown. unknown is only assignable to itself (unknown) and any.
  • Identities: unknown & AnyTypeExpression = AnyTypeExpression, unknown | AnyTypeExpression = unknown

• Prefer over any whenever possible. Anywhere in well-typed code you're tempted to use any, you probably want unknown.

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Deprecating transferPropsTo

It's a common pattern in React to wrap a component in an abstraction. The outer component exposes a simple property to do something that might have more complex implementation details.

We used to have a helper function called transferPropsTo. We no longer support this method. Instead you're expected to use a generic object helper to merge props.

render() {
 return Component(Object.assign({}, this.props, { more: 'values' }));
