Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

Letter to a Young Haskell Enthusiast, by Gershom Bazerman.

Condensed from: http://comonad.com/reader/2014/letter-to-a-young-haskell-enthusiast/

The following letter is about tendencies that come with the flush of excitement of learning any new thing. It is written specifically, because if we don't talk specifics, the generalities make no sense. It is a letter full of things I want to remember.

You’ve entered the world of strongly typed functional programming, and it is great. You want to share the great things you’ve learned, and you want to slay all the false statements in the world.

big data is like teenage sex

- everyone thinks everyone else is doing it

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

	; Ruby has an awesome feature -- string interpolation. Read about it on the internet.
	; On the other hand, Clojure only has cumbersome Java string formatting, which can not be
	; used without pain after you've tried Ruby.

	; So here's this simple macro that basically allows you to do most things you could do
	; with Ruby string interpolation in Clojure.

	(ns eis.stuff
	(:require [clojure.string]))
