<_ko10>
but only one writer thread are permitted (no-reader)
<_ko10>
yes.
<zzak>
that thing that i know very little about
<_ko10>
readers don't change status. so it is acceptable
<zzak>
where is this used?
<_ko10>
multi thread program
<_ko10>
for example:
<_ko10>
many reader threads, and rare writer threads
<zzak>
i see
<zzak>
could you show me an example in ruby?
<_ko10>
binary semaphore (mutual exclusion) stops all of threads except locking thread
<_ko10>
but reader/writer lock accept multiple reader threads
<zzak>
interesting
<_ko10>
now, i'm grepping
<_ko10>
but i can't find out...
<_ko10>
-> ruby's usage
<zzak>
so mutual exclusion is where mutex comes from?
<_ko10>
maybe yes.
<zzak>
np, this is a hard problem
<zzak>
i was going to use it for my talk, but i think its big challenge
<_ko10>
cool!
<_ko10>
at RubyKaigi?
<zzak>
yeah!
<zzak>
maybe ill just add missing overview for SecureRandom (that one is a bit easier)
