systemd is, to put it mildly, controversial. As a FreeBSD developer I decided I wanted to know why.

Join CS50s David J. Malan for a tour of regular expressions--pattern-matching tools that can make identifying and verifying emails, phone numbers, passwords, and so much more all the easier; in this particular stream, well explore them in the context of re, Pythons module that itself is short for «regular expressions», for some real-world utility.
Co-hosted by Colton Ogden. Join us every week live and be a part of the chat at twitch.tv/cs50tv.
In this regular expressions (regex) tutorial, were going to be learning how to match patterns of text. Regular expressions are extremely useful for matching common patterns of text such as email addresses, phone numbers, URLs, etc. Almost every programming language has a regular expression library, so learning regular expressions with not only help you with finding patterns in your text editors, but also youll be able to use these programming libraries to search for patterns programmatically as well. Lets get started…
