talk given by John Ousterhout about sustaining relationships

"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

Created March 8, 2021 11:20
Annotates elements on page with their properties (e.g. font size, colour) so you don't have to open dev tools for testing/debugging
function getProp(elem, prop) {
const propValue = window.getComputedStyle(elem).getPropertyValue(prop);
return `${prop}: ${propValue}; `;
}
function annotateElements(elems) {
for (let e of elems) {
let sBuilder = "<span style='font-size: 8px;'>";
sBuilder += getProp(e, 'font-size');
//add more properties if needed e.g.:

ANY metatype for DNS queries is being phased out, so here is the reimplementation of "dig -t any domain.tld"
#! /bin/bash
# new DNS specification RFC8482 states that DNS servers do not need to respond to ANY metatype
# and can return NOTIMP (not implemented) response for such query. Many of us however, used
# `dig -t any domain.tld` command
# for various debugging purposes. Since more and more servers will be refusing such queries,
# the alternative is to query servers "manually" for every possible record type.
