rcurtinlisitsyn: I think the idea of labeling source via git blame and ordering authors by lines of code committed is really cool.  if you do this, maybe you can point me at the code you used so maybe I can do the same to our code in mlpack? :)01:33

lordonHey guys, maybe one of you guys can help me, I want to do some machine learning stuff with shoguns Ruby modular interface. Unfortunately, when I do exactly the same with Python and Ruby I get different results (The Ruby one is rather bad...) - here you can find two Jupyter notebooks with PCA as example: Python: http://bit.ly/1I9hJhP Ruby: http://bit.ly/1NTw3M3 Any idea?18:31

@besser82lordon, that might be because of the ruy-interpreter...20:02
@besser82ruby20:02

lisitsynuhm this is quite bad21:42
lordonbesser82, I'm using Ubuntu versions 14.10 and 15.04 LTS, ruby 2.2.2 MRI (using rbenv)22:35
@besser82lisitsyn, ?22:39
lisitsynfrom the example I see typemaps seem to be ok22:40
lisitsynbut somehow results differ22:40
@besser82lordon, so your Ruby interpreter is compiled from scratch?22:40
@besser82lisitsyn, mhh...  so testsuite-data is faulty, too?  :/22:41
lisitsynwhy?22:41
@besser82lisitsyn, for me ruby-tests are passing...  so the precomputed results are differing, i asume?22:42
@besser82like we compare with pickles in python-testsuite22:43
lisitsynnot sure if it is covered22:43
@besser82lisitsyn, just checked...  It isn't covered22:47
@besser82:(22:47
lisitsynI am not sure where error could happen22:47
lisitsynI mean under the hood it is the same C++ code22:47
lisitsynso typemaps?22:47
@besser82So we just check if functions in the interface are working22:47
lisitsynbut if they glitch they like explode22:48
@besser82lisitsyn, maybe some difference in float handling with ruby?22:48
@besser82like the interp handled float-precision differently22:48
lisitsynuh should not change it that much22:48
@besser82like with python between ix86 and x86_64  :/22:49
@besser82possibly it's some differnce in numpy vs. narray22:49
@besser82I'll check that tomorrow22:50
lisitsynbesser82: oh would be nice if you get some time22:50
@besser82doing some random (but similar values) float arithmetics with numpy vs. narray and see the outcome22:51
@besser82lisitsyn, I'll do my best...  :P22:51
@besser82lordon, ^ see backlog;  might be because of narray...  Needs some more investigation22:52
@besser82It's bed-time for me, now...  Godd N8, folks!  =)22:52
lordonbesser82 yes, rbenv install compiles ruby from scratch.. thank you guys! I was wondering because I thought the same C++ things were called, too...22:54
