BitKeeper and SCCS

BitKeeper is based on SCCS, a very old, free software version control system. In fact, most of tridge's 'reverse engineering' of BitKeeper consisted of reading the docs to SCCS. Notably, SourcePuller (which tridge wrote) can validate the integrity of the history of a tree many times faster than BitKeeper can.

SCCS was never free software, although the sources to it were available. CSSC is a free-software reimplementation of SCCS.

'bk check' verifies a bunch of properties of the repo, and is IO limited (given at least 256MB of memory). I doubt that SP could make the same integrity guarantees in significantly less time.

we all know tridge is a (reverse-engineering) genius =)

how do i contact you? i was wondering...

i was wondering what you thought of a proposed fair use copyright loophole and if you/someone can implement/integrate/add it into bittorrent.

Here is an idea for legally file sharing: Fair Use.

More specifically, "a quotation from copyrighted material when the excerpt is used for teaching, research, news reporting, comment, criticism or parody."
(http://www.riaa.com/issues/copyright/laws.asp)

For example, a 3 minute song distributed over the internet from one location may violate the copyright law.

But what about a 3 minute song divided into 3 second clips, accompanied by a news report, comment, or criticism, distributed from 60 different locations?
