Here is my massive lib db (for ctfs/wargames/blind pwns etc.). It consists of thousands of libs across over a dozen Linux distributions and architectures spanning the last 20 years. It indexes symbols & gadgets (including one gadgets AKA magic gadgets). https://github.com/0xb0bb/karkinos pic.twitter.com/T76K3lkQ3r

I created a pixel perfect Nyan Cat animation in JavaScript almost 10 years ago. The original gif is 30K while this version is exactly 1K, a reduction in size of almost 97%. If u like JavaScript compression/obfuscation and reverse engineering, have a look! https://demo.skylined.nl/2011-05-01%20Poptartcat%20(Nyan%201K)/ …

Just published a follow-up to my Adobe Reader symbols story on the Project Zero blog. Turns out there's even more debug metadata to be found in some old (and new) builds, including private CoolType symbols. Enjoy! https://googleprojectzero.blogspot.com/2020/01/part-ii-returning-to-adobe-reader.html …

The epidemic will get the travel influencers first. Then come the daily vloggers who walk around outside too much. And the last content to die out will be the gamers on Twitch. Sitting 24/7 infront of the PC doesn't seem so bad anymore!

And the answer is... "xxxx". Most libc implementations (glibc included) apply buffering to stdout. When forking, childs are exact copies of the parent, and they also inherit a copy the internal libc stdout buffer. The buffer is then flushed at exit, by each of the *four* childs.https://twitter.com/MeBeiM/status/1220057648302829570 …

Here's a question: Who is your favorite cyberpunk / sci-fi / fantasy digital painter / pixel artist? Do they do commissions? We've started looking for artists for next covers and would love your recommendations (
