Arbitrary Code Execution With "ldd"
pkrumins writes "The ldd utility is more vulnerable than you think. It's frequently used by programmers and system administrators to determine the dynamic library dependencies of executables.

I researched this subject thoroughly and found that it's almost completely undocumented." -
Free Online Video Education from Top Universities
pkrumins writes "Over the past few years, some of the world's top universities have started offering free video recordings of their lectures. Being a student, I have enjoyed them and collected them in my bookmarks — until recently I talked to few people, and they did not know about it! So I decided to create a blog about free video education online. I am mostly focusing on physics, mathematics and computer science video lectures."
