It's a slower-moving site with lots of CompSci and programmer-focused stuff. People also regularly share what projects they work on, what's going on in their life, or maybe what they're reading. Still has a small community feel despite over 10,000 views a day.
Lobsters and Hacker News are my must reads each day. They're both great. :)
(I'd appreciate an invitation, too: <hnname>@secure.mailbox.org)
Checking now, fro added a paper on fuzzing for side channels in CPU's 30 min ago. Might have missed it if I just looked at morning feed but not later in day.
