Your Favorite Tech / Eng. / CS Books?

Psionicist Here are two suggestions (517 comments)

Introduction to the Theory of Computation by Sipser. This is my favorite computer science textbook together with SICP. It deals with theoretical computer science, mainly automata, computability and complexity theory. It's just 400 pages or so, but covers lots of ground.

Types and Programming Languages by Pierce. This is a very accessible introduction to the theory of programming languages and types.

Cold Boot Attack Utilities Released At HOPE Conference

Psionicist There are some ways to minimize the problem (113 comments)

The way I see this, you should simply not store keys in memory (that is have your encrypted file system mounted) when you not need access to the files. A correct program will overwrite the keys when the file system is dismounted.

The purpose of full disk encryption (or system encryption in TrueCrypt is), in my opinion, not meant as a "one password to protect everything". It's just an extra measure to secure temporary files, the swap file and other tracks the OS and applications may spread around. You should still encrypt your really secret files separately, and use basic precautions such as secure file erasure when you've used them.

That said, I still don't think this attack is so important. If you have the file system mounted, and an attacker gains access to your computer, the files are already there!

Good countries to live in for "nerds"?

Psionicist Psionicist writes  |  more than 6 years ago

Psionicist (561330) writes "What are good countries to live in for tech/science types, such as programmers, mathematicians, scientists or engineers? I'm looking for a country with libertarian tendencies, low taxes, strong protection of civil liberties and no police state laws. As I'm probably not the only slashdotter thinking of moving somewhere else, a discussion about various countries from a nerd/slashdot perspective should be very interesting. How do you like the country you live currently in? Where would you like to move to and why?"
