I would have much preferred to get through three levels of free content then decided the game was shithouse rather than having to learn that at the cost of $70.
Most publishers publish free demos that you can easily download.
If you have a block size of N bits, then there are 2^N possible plaintext/ciphertext blocks, but there are factorial(2^N) possible keys. Think of each key as a permutation of the blocks (which is actually what it is).
Out of those factorial(2^N) keys, only a very very very very very few are actually used, since the key size is nowhere near that large. In AES, for example, the block size is 128 bits, but the largest key size is 256 bits, even though the number of possible keys is 128!. This means that given a random plaintext/ciphertext block, it's actually very improbable that you'd find a key to generate that result.
The only reason that double encryption doesn't provide "double security", is that a meet-in-the-middle attack is possible (see other comments for more details), and that kind of attack only takes twice the time (on average) than a brute force attack on a single key. 3DES provides more security than regular DES, since a meet-in-the-middle attack on 3DES makes its security roughly equivilant to using a 112 bit key (56*2), and that's still too large to be practically broken by brute force alone.
...and also totally irrelevant to this discussion. The question was about source browsing tools, not about source editing tools. The "find" and "find in files" functions that SciTe provides don't really count as browsing tools.

"billions of states" can be achieved with ~30 bits of memory.
I believe that in order to model "any physical computation device" you're going to need many many more states (1KB RAM == 2^8192 states == ~1e2466 states).

It's not support for Wikipedia, but rather support for OpenSearch autodiscovery.
Just configure the three keys as ctrl, alt, and delete.

Maybe if we stacked them...
One can always check the resulting assembly code, if one is so concerned about this.
Though I'm pretty sure this isn't the performance bottleneck in your code (just remember - profile, profile, profile)

Nope. Just swamp gas.
Nothing to see here.
