I'm taking down this post. I just posted this as a side comment to explain a sentence on my latest blog post. This wasn't meant to be #1 on HN to start a huge war on functional programming... The thoughts are not well formed enough to have a huge audience. Sorry for all the people reading this. And please, don't dig through the history...

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

This is my take on how to get up and running with NGINX, PHP-FPM, MySQL and phpMyAdmin on OSX Yosemite.

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

brew install gnupg, pinentry-mac (this includes gpg-agent and pinentry)
Generate a key: $ gpg --gen-key
Take the defaults. Whatevs
Tell gpg-agent to use pinentry-mac:
```
$ vim ~/.gnupg/gpg-agent.conf 
```

@mafintosh asks: "Does anyone have a good code example of when to use setImmediate instead of nextTick?"

https://twitter.com/mafintosh/status/624590818125352960

The answer is "generally anywhere outside of core".

process.nextTick is barely asynchronous. Flow-wise it is asynchronous, but it will trigger before any other asynchronous events can (timers, io, etc.) and thus can starve the event loop.

In this script I show a starved event loop where I just synchronously block, use nextTick and setImmediate

	// Contravariant functors usually have this shape F(a -> ConcreteType).
	// In other words, some type holding a function which is parametric on its input, but not output.
	// They don't always have that shape, but it's a good intuition
	// Covariant functors are what we're used to, which are parametric in their output
