17:10 < vss> hi , for getting the line number in backtrace i found a gnu tool that converts address to file name and line no . So maybe we can use this for #891 ?

17:10 < vss> take a look at this http://www.linuxcommand.org/man_pages/addr2line1.html

17:41 < rcurtin> vss: please take a look at the backtrace code that we already have in mlpack

17:46 < vss> i looked at it

17:46 < vss> both log and backtrace

18:21 < ironstark> I had a question regarding the weka benchmark files. When I run the weka block on my terminal I get an error message that the command could not be executed. How do I run that on my local system

18:22 < rcurtin> ironstark: do you have weka installed on your system, and is the weka jar in your default java classpath?

18:22 < rcurtin> if not you may have to set one of the configuration options in the makefile

18:23 < rcurtin> I dunno if you saw the PR I just submitted, hopefully that should make things a bit easier in the future

18:23 < ironstark> Yes I saw that

18:23 < ironstark> I am working on implementing the same for annoy

18:25 < ironstark> Yes weka is installed. I'll take a look at whether it is in my default classpath or not

18:28 < rcurtin> yeah, if not, maybe the Makefile can be modified

19:37 < zoq> ironstark: You also have to compile the java files for the weka methods either via: javac -cp $(shell echo $(WEKA_CLASSPATH)) -d methods/weka methods/weka/src/*.java or 'make scripts' should also work.

19:40 < zoq> rcurtin: The install script looks great.

20:04 < rcurtin> zoq: if you like it, go ahead and merge it, and I'll start working towards getting Jenkins to use those scripts automatically

20:07 < zoq> rcurtin: done

20:55 < rcurtin> zoq: done with the rmsprop PR? if so I'll hit 'merge'

20:56 < zoq> rcurtin: hit 'merge'

20:57 < rcurtin> easy enough :)

21:27 < rcurtin> ok, finally collector.mlpack.org, the third sparc64 build system, is online and set up in jenkins

21:27 < rcurtin> that one was hard to install because the cd drive was failing, but I did not have any other way to install it

21:28 < rcurtin> so I had to use the existing OS to copy a prepared image from aunty (one of the other sparc64 systems) and then set it up, install the bootloader, etc.

21:32 < rcurtin> not much point in sparc64 build slaves, which is why it hasn't been a big priority, but still fun to have :)

21:45 < zoq> Who could say "hey the code is tested on sparc64" :) and of course we could add a new batch to the readme https://img.shields.io/jenkins/s/http/masterblaster.mlpack.org/job/mlpack%20-%20git%20commit%20test.svg?label=sparc64%20build just because ...

21:53 < rcurtin> hah! yeah we could add another badge I suppose :)

21:53 < rcurtin> someday I will get a MIPS and ARM system online too

21:53 < rcurtin> but there is no way I'll be able to get enough cores of those for a matrix build

22:12 < zoq> ah forgotten to look up collector: http://madmax.wikia.com/wiki/The_Collector here we go

22:28 < rcurtin> zoq: I think it was easier to come up with hostnames from 'Live and Let Die', I think Mad Max has fewer named characters :)
