tom__Hi all13:27
@wikinghey13:27
tom__A question about: HistogramIntersection Kernel13:28
tom__What type of features can I use with that ?13:28
tom__HashDocDot feats are derived from dot feats, does it match ?13:28
tom__HistogramIntersection should use dense features, is there any way to convert string feats, (or hashdocdot feats) into dense feats ?13:29
@wikingtom__: mmm well maybe it'd be better to convert HistogramIntersectionKernel to support other features13:37
tom__When StringFeatures refers to occurence histograms (of ngram etc ..), is it possbile to convert to dense features ?13:43
@wikingmmm13:44
@wikinghaven't been working with stringFeats ...13:44
@wikingmaybe somebody else would have an opinion on this...?13:45

[paladin]Hey. I'm interested in discussing about participating in GSoC 2014. Who do I get in touch with ?18:29
lisitsyn[paladin]: hey18:46
[paladin]hey.18:47
lisitsynI can talk about it I think :)18:47
lisitsynis there anything you want to ask?18:47
[paladin]Yeah.18:48
[paladin]One. I haven't seen any official ideas page for GSoC 2014. So I was wondering what you guys had planned ?18:49
lisitsyn[paladin]: we are working on possible ideas these days18:50
[paladin]Two: do you guys have benchmarking methods implemented ?18:50
lisitsyn[paladin]: examples of ideas are GPs, random forests, MCMC and some frameworks18:51
lisitsyn[paladin]: no not really18:51
lisitsynwe had one in dotfeatures iirc18:52
[paladin]What about an automatic benchmarking tool ?18:52
lisitsynbut not as a general practice18:52
lisitsynif you want to propose such an idea it would be welcome if we are accepted :)18:52
lisitsynhowever we need to think what is it and how should it be done18:53

[paladin]Okay so should I approach when you have a page out to officially discuss ? Later ?18:56
lisitsyn[paladin]: well some kind of18:57
lisitsynalthough it would be cool if you propose your idea in the mailing list18:57
lisitsynso we can comment etc18:58
[paladin]okay. I think that would give me more time to sort of formalise it18:58
lisitsyn[paladin]: sure!19:00
[paladin]great. thanks.19:00

@sonney2kHeikoS, internet sucks here so I am basically offline20:48
lisitsynsonney2k: where you at? ;)20:48
@sonney2kHeikoS, btw regarding funding - we had a paid developer at some stage. So I know that money is not the key to a OSS project's success20:49
@sonney2klisitsyn, Oberwiesenthal20:49
lisitsynsonney2k: is it dirk who is a paid developer?20:50
lisitsyn:P20:50
@HeikoSsonney2k: ok no worries there is still time20:50
lisitsynahh sonney2k having ski time?20:50
lisitsynI am zero-experienced but I tend to agree it is not about money, HeikoS sonney2k20:51
@HeikoSsonney2k: funding would still be nice, but yeah, money is not the thing20:51
@HeikoSbut continuity :)20:51
@sonney2klisitsyn, indeed but he wasn't the only one20:51
@HeikoSso if we could pay sergey, that would be cool20:51
@sonney2kHeikoS, money != continuity20:52
@HeikoSsonney2k: well up to some point it is20:52
@HeikoSjust hour wise20:52
lisitsynHeikoS: even in this case I could fail :D20:52

@sonney2kbut then it is just work20:52
@sonney2kand you loose interest in doing it the way you did...20:52
@sonney2kbut of course there are exceptions20:52
@HeikoSsonney2k: its worth a try20:53
@HeikoSbut yeah, as you said, gsoc first20:53
@sonney2klisitsyn, you are mr. chaos(tm) anywas :)20:53
lisitsynsonney2k: sure20:53
@sonney2kHeikoS, yes indeed20:53
lisitsynsonney2k: isn't it the way everything should work?20:53
lisitsynchaotic!20:53
@sonney2kGSoC gave use much more continuity :)20:53
lisitsynI have to admit I don't get continuity word here20:53
@sonney2klisitsyn, that is how our team works :D20:54
@sonney2kall entropy maximizers!20:54
@HeikoShaha20:54
lisitsynyeah sure I thought max ent is the way20:54
lisitsyn:D20:54
@HeikoSsonney2k: still would be good to have some less new-algorithm based person working on stuff20:54
@sonney2kyeah we had that - it is boring and at some point you wish you would do sth else20:55
@sonney2kbut of course this helped20:55
@HeikoSyeah one needs a good mix20:55
@sonney2kbut not regarding continuity20:55
@sonney2kdifficult20:55
@HeikoSand change targets every now and then20:55
@HeikoSI think we can only win by this :)20:55
@sonney2kML people don't like non-new-algorithm stuff20:55
@HeikoSwiking does :)20:55
@HeikoSsergey too20:55
@sonney2kand hardcore coders get bored with lowlevel stuff20:55
lisitsynHeikoS: we are not ml people ;)20:56
@HeikoSI dont see this so pessimistic and would see its good to try things,20:56
@sonney2kHeikoS, one pressing thing is getting the money btw20:56
@HeikoSevery now and then20:56
@sonney2kHeikoS, sure do it20:56
@HeikoSsonney2k: yeah just reading your email20:56
@sonney2kHeikoS, you just should not be 100% away20:56
@HeikoSsonney2k: I need that money too, fincance is pressing here20:56
@HeikoSsonney2k: I was 100% away from everything over the last months20:56
@HeikoSbut that wont happen anymore in the near/middle future20:57
@HeikoS(I hope at least)20:57
@sonney2kHeikoS, I know20:57
@HeikoSkind of crazy period here20:57
@sonney2kjust after the summit20:57

@HeikoSman deep mind just got bought by google21:08
@wikingthat maybe the students should send in their stuff with different license21:08
@wikingHeikoS: yes21:08
@HeikoSanother scary bit in their puzzle21:08
lisitsynwiking: I vote for BSD/MIT21:08
lisitsynfor new code21:09
@wikingno it's scary how much they paid for it21:09
lisitsyn;)21:09
@HeikoSwiking: deep mind is next door here and most people from the institute go there after phd21:09

@wikingyoyo21:10
@HeikoSbesser82: hi! :)21:10
thoralfHey Bj?rn21:10
lisitsynis there anyone else (but HeikoS) who thinks we should kinda split up to a few smaller libraries?21:10
@HeikoSwiking: how much automatic would that be21:10
@HeikoSlisitsyn: is that a gsoc project?21:11
@wikingHeikoS: well i've done some basic stats by git21:11
@wikingit's doable21:11
lisitsynthis should solve licensing problem a bit21:11
lisitsynI mean we just replace parts21:11
@HeikoSwiking: ok, so maybe I will write an email and put it to disciussion this week21:11
lisitsyndo we need massive -> bsd conversion?21:11
@wikingi mean the core developers can right away assign to the right license21:11
@wikingthe problem is with contributors21:11
@wikingwho are gone21:11
@HeikoSlisitsyn: yeah I would just try things first and then see how it goes21:11
@HeikoSwiking: yep21:11
@wikingbut in worst case21:11
@HeikoSwould be good to have a map of things21:12
@wikingwe can do a rewrite of that code21:12

@HeikoSwiking: yeah maybe later, I would first change everything thats possible and start changing new stuff21:12
@wikinglisitsyn: mmm has to be followed up21:12
@HeikoSand then discuss what to do with the rest21:12
@HeikoSbut guys, what about gsoc, whats your status on that? project ideas? ideas page, proposals? application, who manages?21:13
lisitsynwiking: is it enough to have author will to change anything?21:13
@wikinglisitsyn: yes21:13
lisitsynu sure?21:13
@wikinglisitsyn: but of course if there's an institution connected21:13
@wikinglisitsyn: then u have to get the institution to sign of the change as well21:13
lisitsynhaha21:13
lisitsynthen gsoc 2011 work is kind of lost21:13
@wikingHeikoS: i've promised to write the proposal21:13
@wikinglisitsyn: y?21:13
@HeikoSwiking: on what?21:13
besser82lisitsyn:  several smaller libs / plugin-stuff 4 sure!21:13
@wikingHeikoS: for gsoc... and put in shape the whole project ideas21:14
lisitsynbesser82: good to have people on your side :D21:14
@wikingHeikoS: will do this till wednesday21:14
besser82HeikoS:  me is mentoring SVM^bright && some cmake-based stuff21:14
@wikinglisitsyn: what's the problem with 2011 contribs?21:14
@HeikoSbesser82: cool!21:14
lisitsynwiking: I mean they are all signed as berlin stuff21:14
lisitsynas soeren was in TU at the moment21:14
@wikinglisitsyn: well we can get somebody in berlin to sign it off21:14
@wikinglisitsyn: yeah but there's alex and some other guys still there21:15

lisitsynI have absolutely no clue how this works21:15
@wikinglisitsyn: i've checked up21:15
lisitsyncool21:15
lisitsynthen we are ok21:15
lisitsyn:)21:15
@wikingwe need basically a statement21:16
@wikingfrom the parties that they are ok with the licensing change21:16
@wikingthat's all21:16
@HeikoSlisitsyn, wiking we can just ask and see then21:16
@wikingit's not rocket science21:16
@wikingok21:16
@wikingso fucking let's go with BSD 2 liners21:16
@HeikoSnaywhayare: are you interested in having another project on this inter project comparison stuff?21:16
@HeikoSwiking: yeah I agree on that21:16
@wikingok21:17
@wikingi'll scetch up the statement for that21:17
@wikingthat we can send around to license holders in shogun21:17
@HeikoSwiking: cool, maybe use the vlc stuff as inspiration21:17
@wikingand then we are good21:17
@wikingHeikoS: indeed21:17
@wikingHeikoS: get funding :)21:17
@HeikoSwiking: important part would be to maintain answers decisions and what parts are missing21:17
@wikingif docker got 15M usd...21:17

lisitsynwiking: you got a money you can't spend? ;)21:20
@wikinglisitsyn: nono21:20
@wikinglisitsyn: it's money that i have to spend for associations/fundation, i.e. nonprofit21:20
@wikingotherwise it's lost money21:20
@HeikoSwiking: wherefrom?21:20
lisitsynheh yeah interesting ;)21:20
@wikingbecause then the state will eat that money21:20
@wikingso i rather give that money for something i know...21:20
@wikingHeikoS: have a small company that has to do taxes21:21
@HeikoSwiking: I see21:21
@HeikoSvery cool!21:21
@wikingHeikoS: and i can assign freely 1% of my tax to nonprofit shiatz21:21
@HeikoShopefully next month we are set21:21
@wikingas said if i dont assign it to somebody21:21
@wikingthen it's just lost in the big state budget21:21
@wikinganyhow21:22
@wikinglet's hope we are still in time21:22
@wikingi've talked with vojtech21:22
@wikingabout some qp project21:22
@wikingit'll be a huge project21:22
@wikingi dont know if anybody will be up for that task21:22
@HeikoSok21:22
@HeikoSthat would be cool21:22
@wikingbtw i could do gsoc this year (apparently i still have student status :DDD21:22
@HeikoShaha :)21:23
@HeikoSyou should rather mentor two students ;)21:23
@wikingyeah21:23
@wikingfigured21:23
@wikingok so lisitsyn r u going to lead the modularization ? :)21:24
@wikingi mean if we get into gsoc21:24
lisitsynwiking: yeah I think it would work for me21:24
@wikingcool21:24
@wikingthat should have a prio among the slots21:24
@wikingimho21:25
@wikingif there's a good student up for that task21:25

@wikinglisitsyn: :D21:25
@wikingbtw the whole story with dptrs would be still required even if we do modularization?21:25
lisitsynwiking: I think d-ptr stuff is useful anyways21:26
besser82wiking:  dtpr would be good in some parts, yes  ;)21:26
besser82lisitsyn:  :D21:26
@wikingi guess we would still benefit a lot from it21:26
lisitsynI believe once we get better compile time21:26
@wikingfor the swig interfaces21:26
@wikingor?21:26
lisitsynwiking: don't know21:26
lisitsynwe will see21:26
besser82wiking:  yes, swig would be a cleaner solution  then21:27
@wikinglisitsyn: yeah i think the generated cxx would be heaps smaller21:27
@wikingHeikoS: wha't swith that view thing atm?21:27
besser82wiking: and generation of them cxx wouldn't take 1.5GBytes each anymore  :-P21:27

@wikingHeikoS: indeed21:28
@HeikoSwiking: have a look at the current PR of the guy21:28
@wikingHeikoS: will do21:28
@HeikoSwiking: and then change the x-validation class to use it as a test case (and write unit tests :)21:28
@HeikoSand then it should be ready to be used by others21:28
lisitsynI think 30gb should be the number :D21:28
@HeikoSand if you dont change the copy-by-reference objects, it is threadsafe21:29

thoralfHmm, handling of beta is quite different in libp3bm and libncbm.21:46
thoralfBut libppbm.cpp seems to suffer the same issue.21:47
thoralfline 26521:47
naywhayareHeikoS: sure; we have the framework in place and it could definitely be improved21:49
naywhayareoh, he's not even here.  I should check first ...21:49
thoralfwiking: Thanks for pointing that out.21:51
@wikingnaywhayare: which/what fw?21:54
@wikingthoralf: nw... in the past i've hacked a bit that code21:55
@wikingto make it a bit more shogun21:55
@wikingready21:55
@wiking:P21:55
naywhayarewiking: last year as a GSoC project mlpack had a student who made an automatic benchmarking system22:02
naywhayareI met HeikoS at the mentor summit and we talked about how it would be useful for both of our libraries -- or really all ML libraries in general22:02
naywhayarehere's the last run of benchmarks we had... http://www.mlpack.org/benchmark.html22:03
naywhayareanyway, it needs better documentation, better details, probably a better interface22:03
naywhayareI think HeikoS was interested in adapting the system so it could be used by shogun22:03
@wikingoh cool22:03
@wikingnaywhayare: is it hardwired with mlpack ?22:03
naywhayareI also need to rebuild the benchmarks for your latest release but a paper deadline is on the 31st so it won't be done until after that...22:03
naywhayareno, it's library-agnostic22:03
@wikinggreat22:03
naywhayarewhat the framework really is is just a big python script that runs things and compares how long they take22:04
naywhayareit has a configuration file that defines what to run, what datasets to use, and how to run it22:04
naywhayareand then it has little python scripts individually written for each library's implementation of each method22:04

@wikingnaywhayare: cool it seems there'a lot of stuff we need to fix :P22:07
@wikingin shogun22:07
@wikingi'm just checking GMM results22:07
@wikingnaywhayare: do u have somewhere the code released?22:08
naywhayarewiking: yeah, here's the repo link...22:08
naywhayarehttp://svn.cc.gatech.edu/fastlab/mlpack/conf/jenkins-conf/benchmark/22:08
naywhayareit wasn't really part of mlpack so we put it in our configuration directory for our build server22:08
naywhayareand we have it all integrated with the build server so that it's easy to run tests22:08
naywhayarehere's some further documentation22:09
naywhayarehttp://www.mlpack.org/trac/wiki/AutomaticBenchmark22:09
@wikingok cool22:09
@wikingi'll try to run this myself22:09
naywhayarelike I said it's not completely polished22:10
naywhayarewe did our best to write the scripts for other libraries to use them as well as possible22:10
@wikingno worries22:10
thoralfwiking: libppbm has the same issue - just proven it in a unit test.22:10
@wikingthoralf: \o/22:10
naywhayarethe cover tree is not used for shogun k-nearest-neighbors because john langford's code has a bug he has yet to fix and it returns incorrect results (I think I mentioned this in here a while back; he still hasn't fixed it)22:11
@wikingnaywhayare: maybe we could start a separate repo for this on github?22:11
naywhayarealso, when you see '-' instead of 'failure' for the results, it means the test wasn't run for that particular dataset22:11
@wikingnaywhayare: and then we can get travis to do all the testing? :P22:11
naywhayarethat's just a configuration file issue and I'm in the process of fixing them little by little...22:11
@wikingnaywhayare: how long did it take for u to run the benchmark22:12
naywhayareheh.  the mlpack one takes two weeks22:12
naywhayarethe other libraries tend to take 3-5 days22:12
@wikingoh woah :D22:12
naywhayarewith mlpack we do memory profiling too22:12
@wikingnaywhayare: with?22:12
naywhayaremassif/valgrind22:12
@wikingnaywhayare: do u use some fancy malloc library or the base system?22:12
naywhayarejust valgrind, I'm not 100% sure on the details22:13
@wikingok22:13
naywhayareif you click the rightmost button for a method, then you can open up the 'memory results'22:13
naywhayareand it shows you memory usage for mlpack during the run of the algorithm22:13
@wikingi see22:13
@wikingcool22:13
@wikingwould be great to have that for all the libraries of coursE :P22:13
naywhayareyeah; we did what we could, but time is so little that it's really hard to keep the effort going22:14
@wikingbut then again that's future22:14
naywhayareI have enough trouble just keeping up to date with the five or six libraries we do test22:14
@wikingnaywhayare: totally understand22:14
naywhayarebecause every time a new release happens I have to recompile it on my test system, then ensure the python scripts still work22:14
naywhayare...then wait 3-5 days for the results to be done :)22:14
@wikingnaywhayare: do u think we could get a separate repo for this22:14
@wiking?22:14
@wikingso that anybody can contribute easily22:15
naywhayareyeah, I mean, it's open-source.  =)22:15
@wikingi'm sure ppl here in shogun would be keen to contribute into it22:15
naywhayareideally the student should own the github repo, since it was his work and he knows the most about it22:15
@wikingnaywhayare: yeah no i mean that we could say that we create an official repo at github for it22:15
naywhayaredefinitely22:15
@wikingand then jsut have collaborators for the same repo22:15
@wikingand then PRs can be sent etc22:15
@wikingnaywhayare: r u still in touch with the student?22:16
naywhayareI'm getting in touch with him about it (his irc nick is 'marcus_zoq' and he hangs out in #mlpack or you can pm him); I'll let you know what he says22:16
naywhayareyeah, we still talk regularly, which is good22:16

naywhayareI just did, don't worry =)22:16
@wikingcool great!22:16
naywhayarereally github is a better place anyway than hidden somewhere inside our jenkins configuration22:16
@wikingheheh yeah22:16
@wikingjust with a small link to that page in README.md22:17
@wikingand that's all22:17
@wikingafter that issues and PRs will fly anyways22:17
naywhayarewe submitted the project to the MLOSS workshop but the reviewers bashed it because they were more interested in comparing the accuracy of algorithms instead of the runtime22:17
naywhayarewhereas for the most part we try to ensure that we are benchmarking the exact same algorithms against each other22:17
@wikinghehehh yeah man22:17
@wikingi mean reviewers are like a joke sometimes22:17
@wikingi mean there's like 8 out of 10 papers22:18
naywhayarenah, it wasn't a bad review, his points were valid, but sort of missed the point of what we were doing a bit22:18
@wikingwhere they compare algos22:18
@wikingbut then u know that they fine tuned the last bit of their algo in the paper22:18
@wikingwhile the ones they used for comparison22:18
@wikingjust used as is (default parameters etc)22:18
naywhayareyeah, naturally.  it's really difficult to get a clear picture like that22:18
@wikingso really a thing like this would be great to have22:18
@wikingjsut would be great to automate a lot of part of it22:19
@wikingi mean the test generation22:19
naywhayareso you can use kernel PCA for denoising and alex smola's big paper on it from 1999 has some awesome results... but that paper doesn't mention that when you do image denoising with kpca you still end up with outliers that have incredibly poor quality22:19
@wiking:P22:19
@wikingalex alex22:19
@wikingi wonder where's he now22:19
naywhayarethat was a thing I learned this weekend.  overall, the average reconstructed image quality is great!  but there are just some terrible outliers sometimes.  I wonder if anyone's investigated that22:19
@wikingused to be in canberra22:19
naywhayareeither CMU or Google or Yahoo22:19
naywhayareI met him at ICML... his poster was next to mine22:20
naywhayareI thought that would be great for the publicity of my poster22:20
naywhayarebut actually everyone just talked to him and not me :(22:20
@wikingheheheheheh22:20
@wikingyeah usual22:20
@wikingsorry to hear that though22:20
@wikingbtw how to u store the results?22:20
@wikingi mean is it stored in a db or something?22:20
naywhayareyeah, sqlite db22:20
@wikingok cool22:20
@wikingso basically on the end u can generate historical data as well22:21
@wikingright?22:21
naywhayareyeah, although I don't think we have the support to do that well22:21
naywhayarenot right now at least22:21
@wikingyeah sure22:21
naywhayarebut it can be done; there's just nothing in there that will generate those graphs22:21
@wikingbut if it's stored with a timestamp22:21
@wikingit's really just up to a php/python script to do that22:21
naywhayarehttp://big.cc.gt.atl.ga.us/ there's our build server.  if you open the 'z benchmark' category then you can see each job that we run22:21
naywhayareso when a new release happens, I update it on the system that will be running on the benchmarks (compile with -O3 and whatever), then click 'start job' on jenkins22:22
@wikingcool22:22
@wikinggreat stuff22:22
@wikingi think there's a lot of great stuff that can be done with this22:22
@wikingi mean on the end if u think about it... if this benchmark gets more wide22:23
@wikinglibrary releasers will themselves generate the output22:23
@wikingof their new release22:23
naywhayareyeah, I agree22:23
naywhayarebut again it gets really difficult to compare algorithms sometimes22:23
naywhayareI can compare nearest-neighbor pretty easily because it's exact, but... do I compare it with kd-trees, or with the library's default trees?22:24
@wikingwell of course22:24
naywhayareis the goal of the benchmark to show what a typical user might actually write in code, or to show the actual capabilities of the library?  it gets difficult to answer the question cleanly22:24
@wikingbut there's always going to be problems like that22:24
naywhayarebecause it may be that while I can use mlpack's AllkNN object, it's 5x as fast if I write a far more complex use of some other class22:24
@wikingbut we dont want to solve everything with this benchmark22:25
@wikingrather to show at least basic stuff22:25
@wikingand compare them22:25
naywhayareyeah.  I see those types of problems as a potential source of arguments that I really want to avoid.  I don't want to hurt anyone's feelings :)22:25
@wikingnono i mean i think everybody understands this22:25
naywhayarethere definitely needs to be a lot of clarification on what exactly each benchmark is doing, because it's unclear right now (for instance it just says "ALLKNN")22:25
@wikingbut this is good for everybody both users and library developers22:25
@wikingat least get the bigger picture22:25
naywhayareit's super useful for an internal mlpack development tool, though22:25
naywhayaretrue22:26
@wikingso it's really good ... only that we need to get some more people on board22:26
@wikingbut i think that will not be a problem22:26
naywhayareyeah.  I haven't had the time that I really need to put into this to make it as nice as I'd like it to be22:27
naywhayareanyway a few good GSoC students can get a lot done :)22:27
@wikingwell dont try to do all yourselves :)22:27
@wikingjust put together a repo for it22:27
@wikingand fire up the issues22:27
naywhayareyeah22:27
@wikingi think things will get started22:27
naywhayaremy hope is that Marcus will want to run that22:27
naywhayareafter all, it's his work :)22:28
@wikingheheh yeah22:28
@wikingnaywhayare: the good thing would be to generate a standard API where u can submit your results22:28
@wikingvia http22:28
naywhayareI haven't yet approached the scikit-learn guys.  I told myself I'd do that when I had time but it looks like I'll never actually have time ever again22:28
naywhayareyeah, but the benchmarks aren't useful if they're not run on the same system22:28
@wikingyeah22:29
naywhayarewhich is why we limit our runs to one specific system22:29
@wikingbut one can run the whole test22:29
@wikingon another system22:29
naywhayareah, yeah22:29
@wikingthat's useful as well22:29
@wikingthen u see what's the difference between machine A and machine B22:29
@wikingthere's tons of things that could be done with this22:30
@wikingso let's get marcus on board :)22:30
naywhayareyeah.  making a good interface to be able to actually parse all that data is the really tricky part22:30
naywhayareor, I'm bad at interfaces :)22:30
@wikinghehehe22:30
@wikingi mean honestly it'll be a great thing if this gets picked up around 201522:31
@wikingthat's my optimistic opinion :P22:31
naywhayare:)22:31
@wikingthere's still a lot to work on, but i believe everybody would be interested in this if it would get a little bit more attention22:31
@wiking:P22:31
naywhayaresonney2k pointed out that they tried a similar thing some years ago with http://www.mldata.org but did not see widespread adoption22:32
@wikingone never knows when things go haywire :P22:33

@wiking2 more years and there's gonna b like usa intranet and rest of the world internet if it continues like this22:36
naywhayareI'd like to hope Edward's Snowden's revelations will cause some kind of useful reforms.  but I'm cynical and I doubt it...22:38
@wikingehehhe22:38
@wikingnaywhayare: yeah like with obama and change, right? :D22:38
@wikingin retrospect that was like one of the biggest scam of the states :)22:39
naywhayarein a country as big as ours (or really any big country) it's very easy to be cynical about politics because a single person's opinions can't really effect any change.  which is very frustrating22:40
@wikingehheheh22:40
naywhayareon a very local level, though, like a neighborhood / city level, I've had good interactions with local politicians22:40
@wikingwell things are everywhere the same...22:41
@wikingi bet there's no one single person here who could tell the opposite22:41
naywhayarehah, probably22:41
@wikingwhenever i meet somebody from another country22:42
@wikingthere's one single thing that everybody has in common22:42
@wikingthings are not going well in politics :)22:42
naywhayarehah22:42
@wikingi remember meeting this guy from brasil tell me stories of his own politicans, and in the meanwhile i was like 'yeah i know the story, they did the same...'22:43
@wikingso it's all the same imo22:43
@wikingi bet iglesiasg could share some very positive stuff from the royal family of spain :PPPPP22:44
naywhayareI was in spain recently, I thought it was really nice :)22:44
@wikingheheheheh22:44
naywhayarebut I didn't deal with the politics at all... :)22:44
@wikingyeah that's the rule i always follow when i'm abroad22:44
@wikingignore local politics22:44
@wikingthings are just heaps better then :)22:44
@wikingso lately i follow that rule for my own country's politics... so far so good :22:45
@wiking:)22:45
naywhayareheh22:45
@wikingman i fucking hate hadoop sometimes :)22:46
@wikingthe moment when your 4th job out of 5 jobs dies...22:46
@wikingafter 12 hours :)22:46
@wikingof running time22:46
naywhayareoops22:47
@wikingwith a big fat exception22:47
@wikingthat basically doesn't really say anything22:47
@wikingeven an OOM would be more meaningful22:47

thoralfwiking: Err.  I found a funny bug, that actually has no effect, but maybe you've got an idea how to fix it:23:23
thoralfevery lib*bm defines a BufSize23:23
thoralfWhen calling any solver, the "local" version is used.23:24
thoralfBut when calling libbmrm::clean_icp() and adding an assertion there, the libbmrm-version is used, no matter from which solver it's been called.23:24
@wikingmmm23:31
@wikingthat's most probably a bug introduced by me23:31
@wikingbecause before that the code was just copy pasted among the 3 .cpp23:31
thoralflol23:31
@wikingso i wanted to remove some redundancy23:31
@wikingbut then i guess i've made there a mistake23:32
thoralfActually is has no effect, but it's irritating as soon as you use BufSize from somewhere else. ;)23:32
@wikingsorry for that23:32
-!- shogun-notifier- [~irker@7nn.de] has quit [Quit: transmission timeout]23:33
thoralfCan it be fixed by using the right qualifiers for BufSize?  Something like extern uint BufSize instead of static?23:34
@wikingmmm nasdaq is down 3 days in a row :<23:34
@wikingthoralf: yeah that should work23:34
thoralfI'll check.23:35
thoralfwiking: Err.  NASDAQ?  What happened?23:38
thoralfDidn't read news for days...23:39
@wikingthoralf: mmm well since friday some countries' market is under siege23:39
@wikingso it's all down now :)23:39
@wikingbut mainly it's FED's fault.... they are starting to pull the plug :)23:40
@wikingtapering started basically :)23:41
