sonne|workpluskid: I was just reading your patch thx!09:10
sonne|workpluskid: to get the idea - you introduce multiclassstrategy that can be attached to any multiclass classifier and will generate configurations to be learned by some binary classifier / same with evaluation09:16
-!- n4nd0 [~nando@s83-179-44-135.cust.tele2.se] has joined #shogun09:17
pluskidsonne|work, yes09:18
sonne|workpluskid: that makes a lot of sense - only thing that might be confusing to users is that we have *true* multiclass machines09:19
pluskidsonne|work, the motivation is that blackburn suggest me to write a tree-structure training strategy09:19
sonne|worklike KNN that will directly do everything09:19
pluskidsonne|work, yes, like many MulticlassSVM09:19
pluskidthey handle training directly09:20
sonne|workI think we have only one multiclass svm - GMNP09:20
sonne|worklibsvmmulticlass is also doing OvO09:20
pluskidmaybe LaRank?09:20
sonne|workyes09:20
sonne|worktrue09:20
-!- emrecelikten [~Anubis@176.40.232.233] has joined #shogun09:20
pluskidI think either way (the old and the new) of handling multiclass strategy is OK, if we only have OvO and OvR09:21
pluskidbut if we want to introduce more, this way is more convenient09:21
pluskidespecially when we want to attach some more data to the strategy09:21
pluskidfor example, in a tree-structure training, we need the user to define a tree and attach that to the strategy object09:22
sonne|workpluskid: no your way is much better09:23
sonne|workI mean you should read the ECOC JMLR paper / code09:23
sonne|workthere are so many strategies to do so it is much nicer the new way09:23
pluskidhmm, you are right09:23
sonne|workpluskid: only thing I don't know is how to make clear in the class hierarchy that we have true multiclass machines09:24
sonne|worknot requiring any of this09:24
pluskidyes, and training and applying can also be separated09:24
sonne|workyeah only training is true multiclass for many 'true' multiclass machines09:25
pluskidsome machines use their own training, but use the generic strategy for applying09:25
sonne|workyeah09:25
sonne|worknot clear how to handle that yet09:25
sonne|workpluskid: anyway the best way to proceed is to implement other ECOC schemes from the paper - things will become clear then09:27
sonne|workpluskid: btw I added some (minor) comments to your patch - please address them and then it is ok to be merged09:27
pluskidsonne|work, yes, practicing is the best teacher :p09:27
pluskidOK, I'll look at them09:28

pluskidsonne|work, blackburn I updated the pull request10:52
blackburnyes thanks10:52
blackburnpluskid: have you seen ECOC training code in scikits learn?10:54
pluskidblackburn, no10:54
blackburnpluskid: https://github.com/scikit-learn/scikit-learn/blob/master/sklearn/multiclass.py10:54
blackburnlooks pretty easy actually10:55
pluskidhmm10:56
pluskidI think I understand the basics10:57
pluskidafter reading its comments10:57
blackburnpluskid: yes rather easy - I am also having some long discussion with v. franc about training ECOC svm in true multiclass fashion10:58
pluskidwhat does that mean? "in true multiclass fashion"10:59
blackburnpluskid: in one optimization problem11:00
blackburnimplies better normalization11:00
pluskidOK11:00
blackburnpluskid: I mean in basic ECOC with given K bits11:01
blackburnyou would need to construct K classifiers11:01
pluskidyes11:01
blackburnright?11:01
pluskidso you train the K classifiers in one time?11:01
blackburnI've been thinking about SVM (looks like SO at some place)11:01
blackburnactually I'd like to construct K classifier for each class11:02
blackburnhowever K classifiers at the same time would work too may be11:02
pluskidK classifier for each class?11:02
blackburnhmm yes if I didn't get crazy11:03
pluskidI didn't quite get you, so e.g. we have C class, K bits, then we have CK classifiers11:03
pluskidwith a test point x, how do we classify it?11:04
blackburnmax_{c\in C} \sum_{k\in K} <w_c^k, x>11:05
blackburndoes it make sense for you?11:05
blackburnI am unsure already11:05
blackburn:D11:05
pluskidlet me think11:06
blackburnit is not ECOC :D11:06
blackburndaaamn I have to think about it11:06
pluskidno, this has nothing to do with ECOC11:07
pluskidordinary one-vs-rest linear machine, haha11:07
pluskidmove the sum inside the inner product11:07
blackburnnot ovr11:07
blackburncomposition of K OvR - useless11:08
pluskidhmm, but you can move the sum into the inner product, then \sum_{k\in K}w_c^k can be treated as a single w_c11:09
blackburnah right11:09
blackburnpluskid: no, decision rule is wrong11:10
pluskidblackburn, why?11:10
blackburnshould be11:10
pluskidI don't understand11:11
blackburnshould be different I mean11:11

blackburnsonne|work: which ones?11:20
sonne|workblackburn: like moving around multiclass classifiers11:20
sonne|workand multitask / domainadaptation stuff11:20
blackburnsonne|work: I still think multitask normalizers are better suited to be in transfer/multitask..11:21
sonne|workthen the only remaining intrusive stuff for this year is IMHO sgvector11:21

sonne|workblackburn: look at python_modular13:27
blackburnsonne|work: yes13:30
blackburnI'll fix once I get home13:30
blackburnsonne|work: I think that's ok to patch true multiclass machines13:35
blackburnto avoid this error we can add trained flag there13:35
blackburnso once we train machine we store number of classes13:35
sonne|workblackburn: just think of doing x-validation with Mc machines13:36
blackburnwhat is the problem?13:36
sonne|workfor some subsets you observer x for some x-1 classes or less13:36
sonne|worksame problem with sparse features btw13:36
sonne|workthere could be 1000 dims or 10013:36
wikinghey13:36
blackburn??13:36
blackburnthat is the reason to train on different number of classes?13:36
blackburnno sense for me at all13:37

sonne|workblackburn: you said you want to *infer* number of classes based on labels13:37
sonne|workthat is dangerous13:38
blackburnyes train labels should contain all possible classes13:38
sonne|workI think specifying nr classes is better13:38
sonne|workblackburn: why should they?13:38
sonne|workif you do x-val you might not have some classes13:38
blackburnbad x-val13:38
sonne|worknot bad xval13:38
blackburnbut you will get wrong results!13:39
blackburnsonne|work: how can you ignore some classes?13:40
blackburnso if you skip class C you will have zero w_c, what makes you able to use it?13:42
blackburnwiking: hey13:43
pluskidI support specifying nr classes when constructing a classifier13:43
pluskidjust a matter of taste, however13:43
blackburnpluskid: both ways are ok13:43
blackburnhowever crossvalidation with class ignores makes no sense to me13:44
blackburnthings would be totally wrong if you skip some classes13:44
pluskidI mean it would be easier to implement the code if we are given nr classes at first13:45
pluskidthen no need for a flag like m_trained or similar13:45
blackburnpluskid: where is it set?13:45
pluskidno in current code13:45
pluskidbut I think it might be needed13:45
blackburnpluskid: yes that's I am asking13:45
blackburnon which step?13:46
blackburnah13:46
blackburnnot in current?13:46
pluskidfor example, you do not know the number of machines, until it is trained13:46
blackburnhow does it work now13:46
blackburn?13:46
pluskidfor example, in MulticlassMachine13:47
pluskidget_num_machines()13:47
pluskidwill return "wrong" value, until the machine is actually trained13:47
pluskidWe need to know the state of the machine to see whether some "knowledge" is already available13:48
pluskidhere the number of classes13:48
pluskidthe same problem happens in MulticlassStrategy13:48
pluskidMulticlassStrategy::get_num_machines(int32_t num_classes)13:48
pluskidone has to pass num_classes as an argument when calling the function13:49
pluskidbut if we know num_classes from the begining, there's no need for this argument13:49
pluskidanyway, I think it is just a matter of taste, coz the current solution also works13:49
blackburnpluskid: I think we can assume no ties in labels while training13:50
blackburnhowever it looks like it would be better to store number of classes on training13:50
blackburnand obtain it while applying13:50
blackburnthis way you can be sure it works with ties in test set13:51
wikingblackburn: ho :)13:51
blackburnwiking: does it make sense to you to skip some classes in train set?13:52
blackburn(that are not skipped in test one)13:52
wiking??13:52
pluskidblackburn, I'm OK with this solution13:52
wikingblackburn: why would one do that?13:52
blackburnwiking: x-val13:52
pluskidthough still prefer specifying nr classes in advance :p (my taste...)13:53
blackburnpluskid: in advance?13:53
pluskidI mean when constructing the classifier13:53
blackburnwhen training or constructing?13:53
blackburnpluskid: problem is that if you have ties in labels13:54
blackburnlike test set contains only 1,2, 4 instances13:54
blackburnof classes 1,2,413:54
blackburnI mean13:54
blackburnso get_num_classes would return 313:54
blackburnand you will run only 3 of 4 machines13:55
blackburnskipping last one - it looks incorrect13:55
pluskidI mean in the constructor13:58
pluskidbefore training13:58
pluskidwhat do you mean by "ties in labels"?13:58
blackburn1,2,413:58
blackburnno 313:58
blackburnpluskid: but what if you set different labels?13:58
pluskidbut the number of labels won't change, will it?13:59
pluskidnumber of classes13:59
blackburnwhy not?13:59
blackburnyou can set features, kernel, labels - everything14:00
pluskidYou mean 1,2,4 or 2,3,4, or 1,2,3, etc?14:00
blackburnjust some missing class14:00
pluskidOK14:00
pluskidso we need set_num_classes, haha14:00
blackburnpluskid: yes we need to save num of classes on training14:00
blackburnwe can't rely only on constructor - set_labels() would make no sense then14:01
pluskidblackburn, OK, that makes sense14:01
blackburnhowever this requires to set number of classes in strategy14:02
blackburnin every true svm as well14:02
blackburntrue multiclass*14:02
pluskidyes, that's the problem14:02
blackburnnot really14:02
blackburnoneliner14:02
sonne|workblackburn: I think that is the same issue like having a linear classifier operating on sparse features - sometimes not the last dim in any of the sparse feature vectors is non-zero so you need to specify length of w of the sparse classifier or so14:03
blackburnsonne|work: are you still sure train set can contain a few classes?14:03
blackburn(not all classes)14:04
sonne|worksure14:04
blackburnsonne|work: and how would you classify class X if you haven't trained a classifier for that?14:05
sonne|workit will never predict class X but operate correctly otherwise14:06
blackburnsonne|work: it broke other class' results14:06
blackburnbreak*14:06
sonne|workwhy?14:06
blackburnsonne|work: hmm I assume it would be w=014:06
sonne|workexactly14:07
blackburnsonne|work: it can override some other class scores14:07
blackburnah damn14:07
sonne|work?14:07
blackburn0 always14:07
blackburnhah14:07
blackburnokay sorry14:07
blackburn<0,x>=014:07
blackburnsonne|work: it complicates things pretty much14:08
pluskidI think if the samples for a class is missing, the problem is not with predicting, but with training. You need a one-class algorithm to train a "classifier" :D14:09
blackburnpluskid: I am not even sure that would work with current algorithms14:09
blackburnlike gmnp/etc14:09
pluskidhowever, if this happens, it should be an error14:10
pluskidso if we are specified nr classes, we might be able to detect this kind of error14:10
pluskidbe back in a while14:10
blackburnwe need map there14:11
blackburnto avoid any errors14:11
blackburnwe can't keep things like that anymore14:11

harshit_ted__, hi ,I havn't had much experience with strings in shogun but i think you need to use CStringFeatures<char> as features .16:04
harshit_ted__, have a look at examples/documented/libshogun/features_copy_subset_string_features16:04
harshit_ted__, Also wait for a while till other members are online [blackburn, soeren] they will help you better16:05

harshit_blackburn, I think there might me some issue with svmlin.cpp present in shogun, I have compared the results of original svmlin and that of shogun's, they are close but not exactly similar .16:39
harshit_blackburn, have a look : http://snipt.org/uhjhh316:40
blackburnare all parameters equal?16:40
harshit_blackburn, In svmlin original library we can set lambda so I set it to 116:41
ted__sonne|work, harshit_ : sorry, was away16:41
gsomixharshit_, I think I'll drink vodka in the 17-18UTC and go to bed, aha16:41
harshit_blackburn, but in shogun internaly lambda = 1/2c so I make value of C as 0.516:41
blackburnharshit_: but other params? are there any?16:42
harshit_blackburn, only other parameter is epsilon which is 1e-5 in both16:42
ted__Let's resume: I have samples of different sizes as vectors of float , I am looking for best shogun feature structure and kernel to train multiclass svm.16:43
ted__I'll take a look at StringCharFeatures16:43
ted__what about kernels ?16:43
blackburnted__: vectors of float?16:44
ted__yes16:44
blackburnof variable size?16:44
harshit_gsomix, I think vodka is for blackburn, we should go for tequila !16:44
ted__y16:44
blackburnted__: non-trivial.. how can you compare it?16:44
ted__I know, I'm guessing stringkernel could do the work as they implement smthg like dtw distance ,16:45
ted__?16:45
gsomixharshit_, huh, I have never tried tequila.16:46
ted__It can be vectors of int but sizes are different.16:46
harshit_g2g, blackburn i'll do some more debugging and will let you know about the status !16:46
blackburnharshit_: yeah thanks16:46
blackburnted__: yes makes sense but they are for more 'finite' features like char16:47
harshit_gsomix, you should, maybe today !!16:47
ted__blackburn: and I dont want to use simple bag-of-words representation16:47
blackburnted__: what is the nature of your features?16:47
ted__blackburn: [w1,w2,w3,..] with w_iEUR[0..N] N could be 10, 100, 1000, or 1000016:48
ted__and size of the "string" is not defined16:48
blackburnted__: have you any idea of similarility function? you can create custom kernel actually16:49
harshit_ted__, what I think is that you should first use string to manipulate the words and then prepare its corresponding VSM model which you can store in a normal CSimpleFeatures16:49

ted__I thought that "string kernel" could handle features of different size ?16:52
blackburnted__: yes if they are contained with chars16:53
ted__then clustered by [0,255] ?16:54
blackburnyes would work16:54
ted__Then it could be same algo for string of cluster indices (indices btw 0 and 1000..)16:55
ted__Well, which shogun features/cluster could I overload if I want to do that ?16:56
blackburnted__: could you please clarify what exactly you need?16:56
ted__Well, which shogun features/kernel could I overload if I want to do that ?16:57
blackburnrepeating sentence is not a clarification I'd say :D16:57
ted__blackburn: sry, I just type cluster and meant kernel .16:58
blackburnaha16:58
blackburnted__: you don't really need to overload features for that16:59
ted__blackburn: So. I have a set of indices vector of different size. Let's say Indices EUR [0,100]. Each vector is associated with a label. let's say we have 10 labels.16:59

blackburnstring kernel I mean17:01

ted__LocalAlignmentString ?17:10
ted__Any advice ? :p17:10
blackburnted__: it is based on alignment - I am not sure it would work for your features17:11
blackburnted__: where these features come from?17:11
gsomixpluskid, cool pictures :]17:12
ted__spatial arrangement of my vectors are important: features extracted from video sequence, then I would like to keep the temporal info (=as in ACTCGCT)17:13
pluskidgsomix: you like them? :D17:13
gsomixpluskid, yep17:13
pluskidgsomix: thanks! haha, I like drawing17:14
blackburnted__: really non-trivial thing you do17:14
ted__I know but it seems to be a good way to keep temporal information which is lost in a bag-of-frame algo.17:22

@sonney2kgsomix, I don't know what to explain actually ... is there anything in particular that is unclear?19:18
blackburnref/unref?19:18
@sonney2kI mean just continue to use SGVector& in arguments19:18
@sonney2kblackburn, but the SGVector& stuff is not yet complete or gsomix?19:19
blackburnah this transition should be pretty clear19:19
gsomixhuh, I had planned to discuss it tomorrow. :)19:19
gsomixbut ok19:19
blackburnsonney2k: ok then19:19
@sonney2kgsomix, so please explain :)19:20
gsomixsonney2k, hmm, I already did almost work for SGVector -> SGVector& in arguments, isn't it?19:21
gsomixI am still wondering how to return SGVector from methods.19:22
@sonney2kgsomix, SGVector& except if you return a new sgvectro19:22
@sonney2kSGVector19:22
@sonney2kthen just ^19:22
@sonney2kgsomix, ok?19:23
gsomixsonney2k, it's clear for me. But I worry about how it is then transferred to ref/unref.19:24
-!- harshit_ [~harshit@182.68.43.52] has quit [Quit: Leaving]19:24
gsomixsonney2k, ok, I'll do it in the next few days.19:25
@sonney2kgsomix, we do the ref/unref business after this is done19:25
@sonney2kgsomix, note that this will likely cause some errors that we cannot fix before we have ref/unref stuff19:26
@sonney2kgsomix, if you want to know about ref/unref stuff - let us just copy the functions we have in SGObject for now19:26
gsomixsonney2k, well I think step-by-step strategy is correct.19:27
@sonney2klater on we should investigate whether we add another base class to derive SGVector / SGObject from19:27
@sonney2kgsomix, btw, the same task then for SGMatrix/SGStringList/SGSparseVector ...19:27
@sonney2kSGNDArray .. you name19:27
@sonney2kit19:27
n4nd0sonney2k: a question, why to return SGVector and not a reference?19:32
n4nd0I mean what you said to gsomix ^19:32
@sonney2kn4nd0, if he allocates a new vector within a function (as local variable) - he cannot return a reference to it19:33
@sonney2ksince the reference will be invalid19:33
@sonney2k(object de-allocated when the function returns)19:34
n4nd0wouldn't it better to create the vector to return in the heap?19:34
gsomixblackburn, check a git.19:34
gsomix*github19:34
n4nd0some stuff ... = new SGVector<...more stuff19:35
blackburngsomix: nice19:35
gsomixn4nd0, I think it's not good at now (without ref/unref).19:37
n4nd0sonney2k: well actually SGVector is kind of light, a pointer and a couple of more things so probably the return by value shouldn't be much worse than returning a reference19:37
n4nd0gsomix: do you prefer return by value as well?19:37

@sonney2kn4nd0, too bad - that's really something we should have if we have multiclass enabled QDA20:05
n4nd0sonney2k: just for completeness or is there something else?20:06
@sonney2kn4nd0, multiclass LDA is certainly much more robust than QDA :)20:07
@sonney2kso it is really a very useful baseline method20:07
@sonney2kmuch faster than SVM on low-dim data sets and even optimal when you can assume gaussian distribs20:07

n4nd0sonney2k: I quite don't understand why QDA may fail somewhere LDA successes20:14
n4nd0I thought of QDA as a generalization, within class covariances need not to be equal, so I assumed it would give better results20:15

blackburnfollowers?20:42
n4nd0yeah, I don't know :P20:42
n4nd0I thought you were all waiting for GSoC's answer20:43
PhilTilletn4nd0, GSoC answer? What are you talking about? :p20:43
wikinghahah the crowd gets excited ... ;)20:43
PhilTilletwhat is GSoC? :o20:43
wikingi bet gsoc site will be flooded20:43
PhilTilletlike last year20:43
PhilTilletbut as far as I remember the result is also send by mail20:44
wikinghehehe i wonder why don't they do a caching20:44
wikingand just do a simple precompiled html and that's it20:44
* emrecelikten starts biting nails20:44
n4nd0sonney2k: oh wait, maybe I was handling wrong SG_UNREF in my example20:45
blackburnare you fskin' ready? ;)20:49
PhilTilletf5 spree20:50
blackburnno way to see that even after 5 minutes of deadline20:51
n4nd0haha20:52
PhilTilletyes I know20:52
PhilTillet:p20:52
PhilTilletat first not all the names are loaded anyway20:52
harshit_Is it gonna be same as the organizations names were released ?20:53
PhilTilletno20:53
PhilTilletin principle there's also an e-mail20:53
blackburnemail is pretty late20:54
PhilTilletlast year I had the e-mail 5mins before the deadline20:54
PhilTillet:p20:54
PhilTilletbut I guess it was some bug20:55
@sonney2kn4nd0, can you be more specific?20:55
@sonney2kor attach a gdb bt20:55
@sonney2kI cannot make sense of that20:55
n4nd0sonney2k: I think the double free was caused by SG_UNREF I am doing and shouldn't be done20:56
@sonney2kwhich one?20:56
n4nd0in any case I think that to use more SG_UNREF shouldn't cause that20:56
n4nd0in the example classifier_multiclasslinearmachine20:57
n4nd0the one with which I detected those memory leaks20:57
emreceliktenThe emails are going out20:57

PhilTilletwiking, well, seems like i've loaded everything though21:27
wikingPhilTillet: yeah 774 and it gets stuck21:27
PhilTilletI think we'll have to wait some additional time21:27
blackburnlets have some vodka instead21:27
blackburnwho's in?21:28
karlnapflol, not me :)21:28
PhilTilletI don't drink :p21:28

puffin444Well this is quite suspensful21:30
PhilTilletit's beyond suspens21:31
PhilTillet^^21:31
karlnapfhey guys, i will check back later in an hour or so21:31
puffin444Yeah it's sort of torturous :)21:31
puffin444I wonder how google updates these. Do you think my dashboard/email would tell me first?21:32
blackburnpuffin444: IIRC that list is first21:32
wiking774 is the magic number :D21:33

emreceliktenYep, I'm stuck at 774 too21:34
puffin444I suspect they haven't released all of them at the same time for some reason.21:35
puffin444They did the same thing with the sponsoring organizations21:35
puffin444Some didn't pop up until days after the release data :o21:35
blackburnpuffin444: no with orgs the reason was different21:35
blackburnorganizations had to complete their profiles21:35
PhilTilletI think it's just a bug of theirs21:35
blackburnnot a bug21:36
PhilTilleta feature?21:36
blackburnwith orgs - yes21:36
PhilTilleti was talking about the students :p21:37

PhilTilletblackburn, why so?21:57
wikingsince i'm going to use it and michal as well21:57

wikingso i've started to talk with sonney2k about how to refactor some stuff21:57
blackburnPhilTillet: no real mentor for that21:57
blackburnand no base for that actually21:57

blackburnharshit_: your contributions are welcome too I hope you are not very frustrated!22:01
PhilTilletblackburn, I'll probably do the project on my own :) that's why I sent only one application, there's no point in working in something i'm not fully interested in ;22:02
PhilTillet:)22:02
gsomixhey, congrats guys22:02
harshit_blackburn, no, actually a lil. but still can work on NN for shogun , and my research22:02
@sonney2kPhilTillet, harshit_ let me explain a bit22:03
blackburnyou all have done really a lot of work22:03
harshit_blackburn, but summer could be better with gsoc22:03
@sonney2kI am/was the only mentor for your projects and the one we selected gsomix for22:03
@sonney2kI would have loved to take you both too but I simply cannot handle >1 student22:04
@sonney2kso we decided for the task we needed most - and that is some restructuring / accessibility cleanups22:04
@sonney2kthere was nothing wrong with your proposal or involvement or anything22:04
PhilTilletsonney2k, we know :)22:05
@sonney2kit really is about being at our capacity limits22:05
PhilTilletsonney2k, nothing prevents us from contributing without being paid I guess :)22:05
harshit_sonney2k, no worries :)22:05
@sonney2kand there is nothing I could do about it so late22:05
@sonney2kin the end I *never* expected that we get 9 slots22:05
@sonney2kif I knew that beforehand I would have asked a lot more people :)22:06
PhilTillet:p22:06
@sonney2kanyways whole wikimedia foundation has 8 (or 9?) slots22:06
puffin444Wow22:06
@sonney2kso just to give you some impression how many we received22:06
blackburnwe keep receiving strong gsoc support :)22:07
@sonney2kPhilTillet, harshit_ of course we welcome your contributions22:07
harshit_sonney2k, sure ..!22:07
@sonney2kkarlnapf, do you have a homepage I can link to22:08
@sonney2kpuffin444, ^ ?22:08
@sonney2kand does any of the students here blog? I can put you on shogun planet if you want...22:09
puffin444sonney2k: Not at the current moment. I might be able to make one if you need one though.22:09
blackburnsonney2k: do you think introduction @ mailing list is a good idea?22:09
@sonney2knot required - I just wanted to give it some traffic - hehe22:09
@sonney2kblackburn, I think so22:09
n4nd0sonney2k: I want to take advantage of gsoc and start doing it22:09
blackburnhey guys22:10
@sonney2kblackburn, I totally forgot how we did it last year22:10
blackburnsonney2k: just some introduction mail nothing special I think22:10
@sonney2kblackburn: every student had to send some short email introducing himself + project right?22:10
blackburnyeap22:10
blackburnn4nd0: puffin444: wiking: karlnapf: gsomix: could you please do this ^?22:10
blackburnkarlnapf: however you are well-known22:10
@sonney2kbut still22:11
blackburnyes there is a need to introduce your project22:11
@sonney2kyou can look up in the mailinglist archive how these things look like22:11
n4nd0all right22:11
blackburnjsut some short introduction22:11
puffin444blackburn: Yeah sure.22:11
@sonney2kthe other more annoying job is to send a weekly update (from the official beginning to end of gsoc)22:11
blackburnand some feature plan would be nice22:11
@sonney2kso another short email22:12
@sonney2k*short*22:12
