ok brandon, that's a thought. build the hash on the hard drive at the time of
data creation. you mention collision resolution. so let me build my hash on the
hard drive using my 6 million buckets but increase the size of each bucket from
5 slots to 20. right? i can't exactly recreate my vector/b

alright george, i'm open to new ideas. here's what i've got going. running 64
bit linux mint OS on a 2 core laptop with 2 gb of ram. my key is 128 bits with
~256 bits per record. so my 1 gb file contains ~63 million records and ~32
million keys. about 8% will be dupes leaving me with ~30 million
+1 on George Neuner's comments about how one can do smart processing of
huge files in small space. (I almost said something about that myself,
but didn't have time to get into that kind of discussion, so I stuck to
only the simpler file concatenation question.)
BTW, students who have 8GB RAM

In my case, the default browser is Chrome, and it was alread

Awesome - thanks. I'm not sure if you meant 'insertion point is on the word
"filter" ', or not, but for fun, I hit F1 with the insertion
In DrRacket you can type f1 when your insertion point is on the word "help".

is nice and fast and easily fit into the existing code.

There's also the glob package [1], which should give the exact same API as
the shell. No need to remember the trailing "$" or specifically exclude
dotfiles.
