I guess I have not posted anything tacky on G+ in a longer while. To make up for this:

Poland is an ancient country whose history is deeply intertwined with that of the western civilization. In its glory days, the Polish-Lithuanian Commonwealth sprawled across vast expanses of land in central Europe, from Black Sea to Baltic Sea. But over the past two centuries, it suffered a ...

Tacky?  Pfft.  An awesome personal story with plenty to ponder over.

Why should I care? If someone doesn't want to see me, please just don't look at my window :)

Fuzzing is one of the most powerful strategies for identifying security issues in real-world software. Unfortunately, it also offers fairly shallow coverage: it is impractical to exhaustively cycle through all possible inputs, so even something as simple as setting three separate bytes to a ...

I originally released afl-fuzz in November of 2013. Back then, it was simply another take on an idea I first toyed with in 2007, inspired in large part by the work on corpus distillation done by Tavis Ormandy. It almost ended up in the dustbin of history: early on, the project had many ...

This is an interesting demonstration of the capabilities of afl; I was actually pretty surprised that it worked! $ mkdir in_dir $ echo 'hello' >in_dir/hello $ ./afl-fuzz -i in_dir -o out_dir ./libjpeg-turbo-1.3.1/djpeg. In essence, I created a text file containing just "hello" and asked the ...

Fuzzing on Edison: field report. When Intel Edison came out in September 2014, it caught my eye not only because of my unhealthy obsession with robotics, but also because it seemed like an interesting platform for security enthusiasts to perform hobby fuzzing work. For those of you not familiar ...

It's interesting though.. I mean - even if we assume that for a 1U server (let's say it's 100x faster than Edison with multi-core multi-CPU setup) we can pack like 500 of such boards, nobody really does that for CPU farms (to maximize space/speed ratio). Maybe the heat dissipation would be a problem, maybe the supporting infr. (power, network).
