"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation

Jepsen V (Kyle Kingsbury)

Talks about how Jepsen works and what systems have been tested until now, among others:

Riak: default is last-write-wins, but you should not be using it
ZK: works as advertised (!)

... But all of this is also on his blog, not anything really new.

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:

	(ns webdav
	(:require [clojure.string :as str]
	[clojure.data.xml :as xml]
	[org.httpkit.server :as hk-server]))

	;; add the XML namespace that we'll use later
	(xml/alias-uri 'd "DAV:")

	(defn dissoc-in
	"Should be in the standard library..."
