sonne|workblackburn: agreed16:24
blackburnI wrote too much to understand what is you agree with :)16:25
sonne|workit is bad to do d[i,j] and d[j,i] in the same time16:25
blackburnah yes16:25
sonne|workdid you write more than that?16:25
blackburnwell yes, for last two days16:25
blackburn;)16:26
blackburnsonne|work: I can hardly wait to release16:26
blackburncause I can't post on mloss and submit paper16:27
blackburnblocks me a little16:27
sonne|workheikos stuff needs testing before we can16:27
sonne|workthen do a snapshot16:27
blackburnof current version?16:27
blackburnhow&16:27
sonne|workIIRC make release SNAPSHOT=yes16:28
blackburnhmm makes sense16:28
blackburnsonne|work: have you seen I did integrate covertree?16:31
blackburnI know you probably not a big fan of std things but it works smooth, that's definitely better than nothing16:31
sonne|workno havent seen it16:31
sonne|workno time now16:31
blackburnsonne|work: well then you know it now :)16:32
sonne|workwhere is it?16:32

@sonney2kblackburn, what should index_t be?16:57
blackburnsonney2k: unsigned?16:57
@sonney2kwell possible if you are carefull with signedness everywhere16:58
@sonney2kwould probably be a big change16:58
blackburnI think we should -> to unsigned some day16:58
@sonney2kblackburn, do you know whether gsoc got announced already?16:58
blackburnsonney2k: not yet16:58
@sonney2kthen things like for int i=0 i< size ; ... won't work16:59
blackburnsonney2k: why?16:59
@sonney2kwe would have to go through all loops and convert them to for index_t i=0 ...16:59
blackburnhmm yes, but not a big change16:59
@sonney2ksome of these are doing plus minus operations like17:00
blackburncan be done gradually17:00
@sonney2ki-j17:00
@sonney2kand check if things are >017:00
@sonney2kcan be done but lot of work17:00
blackburnsonney2k: it leaves room for optimization I think, i.e. when compiler knows i is unsigned17:00
@sonney2k?17:00
@sonney2kwhat does it help?17:00
blackburnI'm not sure though17:01
blackburndon't you think it would be better for compiler17:01
blackburn?17:01
@sonney2kunderneath (machine language) signed / unsigned is no difference17:01
blackburnwell, for example loop to zero is faster17:02
@sonney2kno17:03
@sonney2ksame thing17:03
blackburnsonney2k: I am not sure, zero test could be faster :)17:05
blackburnsonney2k: have you seen my benchmark vs scikits?17:05
@sonney2kunsigned int u=0 ====== int u=0 :-)17:05
blackburnfinal one17:05
@sonney2kall bits 017:05
@sonney2kno17:05
blackburnyou could check if you want17:05
@sonney2kwhere?17:05
