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:

;; -*- mode: lisp -*-
;;
;; A quick and dirty tree shaker for SBCL.  Basically, it destroys the
;; package system and does a gc before saving the lisp image.  Gives
;; about a 40% reduction in image size on a basic hello world test.
;; Would like to hear how it works on larger projects.
;;
;; Original idea from: https://groups.google.com/d/msg/comp.lang.lisp/6zpZsWFFW18/WMy4PyA9B4kJ

Around 2006-2007, it was a bit of a fashion to hook lava lamps up to the build server. Normally, the green lava lamp would be on, but if the build failed, it would turn off and the red lava lamp would turn on.

By coincidence, I've actually met, about that time, (probably) the first person to hook up a lava lamp to a build server. It was Alberto Savoia, who'd founded a testing tools company (that did some very interesting things around generative testing that have basically never been noticed). Alberto had noticed that people did not react with any urgency when the build broke. They'd check in broken code and go off to something else, only reacting to the breakage they'd caused when some other programmer pulled the change and had problems.

Principles of Adult Behavior

1. Be patient. No matter what.
2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
3. Never assume the motives of others are, to them, less noble than yours are to you.
4. Expand your sense of the possible.
5. Don’t trouble yourself with matters you truly cannot change.
6. Expect no more of anyone than you can deliver yourself.
7. Tolerate ambiguity.
8. Laugh at yourself frequently.
