[conspire] Evan Prodromou interview about Laconica (open source Twitter)

[Rick Moen]

Interview with Evan Prodromou about his open source microblogging engine
(Laconica[0]), and his Montreal-based service Identi.ca that runs it.
Laconica includes an interoperable clone of Twitter's messaging API
(i.e., prevents your Twitter "tweets" from being trapped in a Web 2.0 
roach motel).

Evan includes some surmises about Twitter's internals (using Ruby on
Rails), which are interesting.


Separately, Rasmus Lerdorf did a talk about his studies of Laconica
performance bottlenecks:  He was able to more than double performance
easily with a little work -- (mostly) making include paths fully-qualified
instead of relative.   He also set "apc.stat = Off"[1] in php.ini, used the
"inclued" PHP extension[2], cleared out some unnecessary and
performance-hogging "XMLWriter"[3] stuff that wasn't needed, deployed
strace/Valgrind/gdb/XDebug[5]/Siege[6] to spot the trouble spots, and used
APC Cache[4].
