ogd: if your c++ experiment succeeds i'm assigning the libutp bindings to you

mafintosh: that does not motivate me

o/ from the lbfs paper (http://cis.poly.edu/cs623/lbfs.pdf)

ogd: oh ok - then what i said about you having to do a table probably isnt true

mafintosh: we should probably read that whole paper btw

e.g. "The maximum chunk size is 64K. If the file contents does not produce a breakpoint every 64K, LBFS will artificially insert chunk boundaries. "

ogd: yea i agree

ogd: still wanna do a js version at some point as well for the browser

mafintosh: that'd be great one day

ogd: (thats gonna be way easier with the c++ reference impl working from js though)

karissa: im tackling the file chunking stuff jsut to get it out of the way. writing a c++ module hehehe

ogd: oh wow!

karissa: i think its gonna be pretty easy actually

ogd: great

ogd: point me to the repo!

karissa: check otu thi spaper http://cis.poly.edu/cs623/lbfs.pdf

karissa: https://github.com/maxogden/rabin

ogd: got it

mafintosh: also check out this guys papers https://pdos.csail.mit.edu/~benjie/

ogd: lol at the massive relevance of all those papers!

mafintosh: http://calagator.org/events/1250469319

karissa: clone https://github.com/maxogden/rabin

karissa: run npm link

karissa: then run node test.js some-file-that-is-at-least-10kb-of-plaintext.txt

karissa: then go into that file in an editor and add some letters in the middle of the file

karissa: then run the test.js command again and compare the hashes with the previous one

ogd: nice testing after din

L* https://pdos.csail.mit.edu/~benjie/papers/podc0...

do any of you have recomendations on materials for learning how to work on and write native addons for node?

karissa: did you get the rabin module working?

ogd: totally forgot was just working on the cli

ogd: i'll do it in a min

karissa: im just curious if it will work on another computer lol

ogd: for sure

uhhyeahbret: some good modules to look at are mknod, fuse-bindings

ogd: yeah it worked

karissa: woot

ogd: :)

dat/new-dat 983f143 Karissa McKelvey: 1.0 roundup

mafintosh: ogd: what do you think about this as a first list of things to do before we can do a resonable demo ? https://github.com/maxogden/dat/blob/983f1436a0...

mafintosh: ogd names/workflows will likely change

karissa: that seems about right

maxogden/dat - 1.0 roundup - failed - https://travis-ci.org/maxogden/dat/builds/89497105

ogd: its easy if the problem is constrained to reasonably sized files, but the workflow very Very Large Files is still a big question mark.

karissa: oh yea good point.
