[racket-users] Re: appending files

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

neil van dyke, i have used the system function before but had forgotten what it was called and couldn't find it as a result in the documentation. my problem with using the system function is that i need 2 versions of it: windoz and linux. the copy-port function is a write once use across

gneuner2 (george), you are over thinking this thing. my test data of 1 gb is but a small sample file. i can't even hash that small 1 gb at the time of data creation. the hashed data won't fit in ram. at the time i put the redundant data on the hard drive, i do some constant time sorting so that
