Very sad. _Prime Numbers - A Computational Perspective_ (a.k.a. "Crandall and Pomerance") is a seminal book in that field and introduced me to very useful concepts such as Montgomery multiplication.

It depends on the setup. I've seen a CMS brought almost to its knees because the previous owner of that IP had a site that had lots of distinct pages on it. Since every page in the CMS was stored in a DB it took a DB lookup to find out whet

Many, but not all, of those algorithms will work for numbers which are a product of two roughly even sized primes (depending on size). Especially the Quadratic Sieve and Number Field Sieve class of algorithms (NFS, GNFS, SNFS, etc). Size is

As someone with both a Bachelors degree in Computer Science and a Bachelors degree in Mathematics I'd agree. My CS degree was quite theoretical (completed in 1999) so it wasn't just being taught the language of the day (we did x86 assembly,

n(n+1)/2 also exists as a simple direct method of summing a series of 1..n. There's no similar (obvious) shortcut for n! (I don't count lgamma as obvious...)

Hanger Lane is scary as most drivers haven't realised that it's not really a (proper) roundabout any more. On a normal roundabout if you stay in a lane (one of the inside ones at least) you'll just keep going round and round. With the redes

The lawyer-ish response to that would be that such a change could be considered an admission that, at the time of the original campaign, the T&Cs weren't clear on this matter and that some people therefore had expectations of a guarante

Sure, but a hash collision for a specified value is still a needle in a haystack. The sheer size of the keyspace (2^128) means that rainbow tables can only ever exist for a subset of the keyspace. 1M machines running for a year each capable

Thanks for the clarification, I did say they were examples (they were the first results I found in a quick google) and that you should use epsilon values appropriate to the values you are comparing.

The + trick is becoming well known with spammers anyway. I registered with one site as "something+else@example.com" having never used the "something@example.com" address anywhere and within a few days I was getting spam to "something@exampl

That's why you don't compare floating point numbers with the = operator. You use something like: fabs( a-b ) < epsilon where epsilon is usually defined by the language as a very small quantity (example values in C are 1E-8 for
