FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Regular Expression Engine Comparison Chart

Many different applications claim to support regular expressions. But what does that even mean?

Well there are lots of different regular expression engines, and they all have different feature sets and different time-space efficiencies.

Falsehoods programmers believe about addresses

This is an anchor-linked version of the excellent, amazing original opus magnum by Michael Tandy.

An address will start with, or at least include, a building number.

Counterexample: Royal Opera House, Covent Garden, London, WC2E 9DD, United Kingdom.

When there is a building number, it will be all-numeric.

Counterexample: 1A Egmont Road, Middlesbrough, TS4 2HT
