ReDos, also know as Evil Regex, is a regex that given a very
specific input can result in exponential processing time. This
exponential processing time will cause excessive CPU usage and may
block processing of other requests.
ReDoS became infamous in 2016 when a misconfigured regular
expression accidentally took down Stackoverflow.

In the evening Alice, Esme, and I watched Alien: Covenant
(2017). Adam watched at first
as well but considered the movie too scary for his taste and went up
to his bedroom to read "The Hobbit". I did like the movie and give it
a 7.5 out of 10.
