Paper: Hyperscan: A Fast Multi-pattern Regex Matcher for Modern CPUs
a software based, large-scale regex matcher designed to match multiple patterns at once (up to tens of thousands of patterns at once) and to ‘stream‘ (that is, match patterns across many different ‘stream writes’ without holding on to all the data you’ve ever seen). To my knowledge this makes it unique.

RE2 is software based but doesn’t scale to large numbers of patterns; nor does it stream (although it could). It occupies a fundamentally different niche to Hyperscan; we compared the performance of RE2::Set (the RE2 multiple pattern interface) to Hyperscan a while back.

Most back-tracking matchers (such as libpcre) are one pattern at a time and are inherently incapable of streaming, due to their requirement to backtrack into arbitrary amounts of old input.

Rudy Giuliani doesn't understand how links work
As waxy noted: 'this might be funny if he wasn't Trump's cybersecurity advisor'.
Twitter allowed someone to invade my text with a disgusting anti-President message. The same thing-period no space-occurred later and it didn’t happen. Don’t tell me they are not committed cardcarrying anti-Trumpers. Time Magazine also may fit that description. FAIRNESS PLEASE

Giuliani composed a tweet with no spaces after full stops, and a broken regexp at Twitter auto-linkified "G-20.In". An internet prankster registered this domain and Giuliani lost his shit in a spectacular display of incompetence.

The best bit? Here's a thread with the original devs: -- 'Hey @tw and @bcherry, remember all the debates we had about the linkifying regex around edge cases like this?'

(via Waxy and pretty much everyone on twitter)
