13:57 < Kallor> Hello, I'm new here

13:58 < Kallor> I'd like to contribute and I have good grasp on algorithms

13:58 < Kallor> But would I need specialized knowledge in machine learning to contribute?

14:09 < naywhayare> Kallor: not necessarily, but it's certainly helpful

14:09 < naywhayare> if you've downloaded mlpack and looked through the tutorials (http://www.mlpack.org/tutorial.html) and have a basic idea of how the library is laid out,

14:09 < naywhayare> you might consider looking at the Github issue tracker: https://github.com/mlpack/mlpack/issues

14:10 < Kallor> naywhayare: thank you :)

14:10 < naywhayare> most of them are marked with a difficulty, so that might help you figure out some issues that you can handle

16:56 < Charly_> Hi !

16:57 < Charly_> I'm new to mlpack and not really good with Ubuntu and I fail installing it... Someone can help ?

17:00 < Charly_> Can someone help me please ?* (sorry, I'm suite tired, my english is worst each minute passing)

17:02 < naywhayare> hi Charly_, if you are on Ubuntu why not just install it through apt?

17:03 < naywhayare> i.e. apt-get install libmlpack-dev

17:03 < Charly_> I followed instructions from the website

17:03 < naywhayare> an install through apt will be easier

17:03 < naywhayare> but if you want to compile from source I can help

17:04 < Charly_> hmm.. ok, i'll go kill myself for the last 30 minutes and retry ><

17:04 < naywhayare> but I need to know the errors that you encountered

17:04 < naywhayare> no need to kill yourself... :)

17:04 < Charly_> just joking, I'll install it with apt

17:04 < Charly_> but I'm curious

17:05 < Charly_> my error is at cmake step

17:05 < naywhayare> okay

17:05 < naywhayare> can you paste the output?

17:05 < Charly_> The CXX compiler identification is unknown

17:06 < Charly_> the entire message

17:06 < Charly_> "-- The CXX compiler identification is unknown CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name. -- Armadillo libraries: /usr/lib/libarmadillo.so CMake Warning at CMakeLists.txt:88 (message): This is a 64-bit system, but Armadillo was compiled without 64-bit index support. Consider recompiling Armadillo with ARMA_64BIT_WORD to enable 64

17:06 < naywhayare> ah, you probably don't have gcc installed

17:06 < naywhayare> or g++ or clang

17:06 < Charly_> certainly

17:06 < naywhayare> you could get that tjroug

17:06 < naywhayare> *you could get that through apt

17:07 < Charly_> it says I already have gcc

17:07 < Charly_> must be with Ubuntu now

17:08 < naywhayare> but you need g++ too

17:08 < Charly_> I test that =)

17:09 < Charly_> my hero \o/

17:09 < Charly_> thanks !

17:10 < Charly_> I work in machine learning with windows for too long I guess ^^'

17:10 < naywhayare> :)

18:31 < stephentu> naywhayare: that sounds like a lot of fun

20:19 < naywhayare> stephentu: the weird DNS issues? yeah...

20:20 < naywhayare> it looks like it's some bizarre spanning tree issue -- but I can't say more than that since it's been years since I've debugged networks and also because I'm not the one doing the debugging :)

20:20 < naywhayare> I'm waiting on a new switch to drop in place in hopes that it will resolve the issue

20:21 < zoq> I guess big is down for the same issue?

20:21 < naywhayare> yeah, I tore out all the network cables for testing

20:21 < naywhayare> it's a very odd issue... connections have no problems to systems on the 143.215.129.x and 143.215.131.x subnets

20:21 < naywhayare> but sometimes fails for the 143.215.128.x network (which is what bodyguard, the NFS server, is on)

20:26 < zoq> This random issues are hard to track down and it is even harder if you can't just debug the network by yourself

20:27 < naywhayare> apparently those particular switches are known for overheating, and maybe putting it in the middle of the stack has caused it to fail because of heat or something...

20:27 < naywhayare> maybe life would be a million times easier if we just used EC2 instances

20:27 < naywhayare> but that would be less fun :)

20:31 < zoq> Yeah :) where is the fun using this http://www.datacenterknowledge.com/wp-content/uploads/2011/04/Server-room6.jpg when you can use ... I can't find the picture from the build farm

20:32 < naywhayare> ooh man, I wish I could have stuff in a shiny server room like that

20:33 < naywhayare> I think maybe I need to graduate and save a little money up first...

20:37 < zoq> Maybe you can pick something from the list https://support.cc.gatech.edu/facilities/research-clusters :)

20:37 < naywhayare> I need to figure out what they do with those when they retire them

20:38 < naywhayare> I have an account on a few of those clusters but I doubt they'd like it if I was using all the nodes to compile mlpack every night...
