For example, I've read on some math-programming forums that by using the Quadratic Sieve or the General Number Field Sieve, one can factor a 256 bit number with relative ease on commercially available hardware. How does this translate to being able to b...
So, I've got a query that looks something like this: SELECT id, DATE_FORMAT(CONVERT_TZ(callTime,'+0:00','-7:00'),'%b %d %Y') as callDate, DATE_FORMAT(CONVERT_TZ(callTime,'+0:00','-7:00'),'%H:%i') as callTimeOfDay, SEC_TO_TIME(callLength) as callLength FROM cs_calldata WHERE customerCode='999999-abc-blahblahblah' AND ...
