Nope, you're still right. Assume startups fail 90% of the time. 50% of the time your coin comes up tails, and you claim the startup will fail. 50% of the time your coin comes up heads and you claim the startup will succeed. You guess c

Yup. The xadd opcode adds the two registers together and swaps them so that the previous element is always in the same register.

Agreed. The second snippet ( http://www.xorpd.net/pages/xchg_rax/snip_01.html ) is relatively simple to understand and is now my favorite two opcode program.

bcrypt and scrypt are always salted (it's part of their algorithms - there is not such thing as unsalted bcrypt/scrypt)

Incredible. Save the program to a file and run: runhaskell quine.hs | python | ruby to get the original file. If you look it through it's just a trivial extension of the "classical" quine. The function q prints it's arguments followed by pr

What the hell? Seriously. This was not a silly one line meme reminiscent of reddit. Someone posted a long, well written story questioning the social implications of a new piece of technology, which generated a huge amount of discussion. A o

How about this: http://blog.fortify.com/blog/fortify/2009/02/20/SHA-3-Round-... ? Granted, these were just candidates and not actually NIST defined algorithms, but the point stands that algorithms can be fine while standard implementations

Using a slow implementation of PBKDF2 is not going to slow down attackers who use a fast implementation.

Don't bother with the else. Just continue with your code outside a nested block since the if returns.

He didn't say the item doesn't apply, he said that it is a warning sign. Holding a contest doesn't make a product snake oil, but it certainly correlates to snake oil products.

So in the case of software, how is a patent different from a copyright on your code?

by jgeralnik 14y ago
[..] to accept that the functionality of a computer program can be protected by copyright would amount to making it possible to monopolise ideas, to the detriment of technological progress and industrial development. How are patents justi

The systems we use now use salts. If they don't they are doing it seriously wrong.

Just because supposedly a piece of software performing a critical purpose was written in lisp does not mean lisp won the war. If the software wasn't written in lisp, it would have been written in any other language. And if the software wasn
