You're right, it's not official documentation, but it was the first thing I read when I decided to start learning Mongo. I've also seen 10gen hand out hard copies at meetups in NYC. Anecdotal, I know, but maybe helpful to someone. There's a

This guy only used 302 from a dump of 453,491 passwords to come to these conclusions. I can imagine no reason why he'd intentionally invalidate his analysis by using such a low sample size unless this conclusion doesn't actually hold when y

Slightly OT, but I wouldn't say that R was "built for large scale analytics." You have to go through some serious hoops to work on anything in R that takes up more than 50% or so of available RAM. Revolution Analytics's R build is designed

If you are equipped to hunt bear, you are almost certainly not using an automatic. Any caliber high enough to drop a bear in one shot (which you want to do as to not ruin the bear) would break your arm into slivers were you to fire it at au
