diakopter if I can find/discover an appropriate scalable queue lock, I can get rid of 5million failed CAS/s 08:56
bonsaikitten why is the locking needed? (iow, are lockless algos maybe useful here?) 08:58
diakopter the "lock" is really just access to the memory each wants to CAS. So, to remove contention on that location, a queue lock can be used. it's for implementing a lock-free algorithm 09:00
heh. 09:01
well hmm, never mind, seems I confused myself there again. a queue lock wouldn't help. sry nm 09:02
but I need something to reduce CAS contention. simple exponential backoff is helping a little, but it's constraining throughput 09:03

grondilu posted a question about style for plural form for names of variables: perlmonks.org/?node_id=1002881 11:56
^ what dyou think about this, guys? 11:57
I know it's not a big problem but it's kind of annoying me each time I have to chose a name for an array variable. 11:58
cognominal grondilu, where are you living? 11:59
grondilu France. Why?
cognominal near Paris?
grondilu No. I left Paris a few months ago. I live in Picardie, now. 12:00
cognominal do you know the mongueurs?
grondilu Not much.
cognominal ha, too bad.
I have seen you are taking over the French wp article about Perl 6. that's good because I have not updated it much the last few years 12:01
there is some crap (about history mostly) added by well intentionned people I did not remove to not discourage further collaboration that did not materialize. I hope you will be more drastic than I was. 12:03
grondilu, there is a french channel #perlfr on irc.perl.org 12:05
12:05 cognominal left
grondilu "taking over" is not the right expression. I just thought is need a sreious update indeed. But I don't have much more ideas about what to add now. 12:05

I don't think there is anything about roles because they were not implemented when I wrote the article. 12:08
