| @sonney2k | july | 09:54 |
| @sonney2k | foulwall`, you have to adjust the gp example a bit the syntax changed | 09:55 |
| foulwall` | aha? | 09:55 |
| lambday | sonney2k: looking forward to the video recording.. :) | 09:56 |

| @sonney2k | lambday, I hope we can get some equipment for that | 12:12 |
| @sonney2k | van51, did what I wrote make sense? | 12:16 |
| van51 | sonney2k: yeap | 12:17 |
| van51 | sonney2k: what I didn't quite get is for the nnz_features, why would the string length be better | 12:17 |
| van51 | sonney2k: what I was/am thinking of doing there is to use the converter to transform the document to a SGSparseVector and store it and iterate it | 12:21 |
| @sonney2k | van51, no the point is to do that on-the-fly | 12:25 |
| @sonney2k | van51, and the nnz_features was IIRC just an estimation so an upper bound is fine | 12:25 |
| van51 | sonney2k: but you can't iterate the features on the fly | 12:25 |
| van51 | the nnz* features on the fly | 12:25 |
| @sonney2k | why not? | 12:25 |
| van51 | you may get the same one again and again | 12:25 |
| @sonney2k | that is ok | 12:26 |
| van51 | and not in the correct order | 12:26 |
| @sonney2k | also ok | 12:26 |
| van51 | ok then :P | 12:26 |
| van51 | these were my arguments | 12:26 |
| @sonney2k | just think of it | 12:26 |
| @sonney2k | add_to_dense_vec | 12:26 |
| @sonney2k | will then just add the thing multiple times | 12:26 |
| van51 | sonney2k: ah wait | 12:26 |
| @sonney2k | and dense_dot same thing | 12:26 |
| van51 | sonney2k: I'm not talking about these methods | 12:26 |
| @sonney2k | ignore the feature iterators | 12:26 |
| van51 | sonney2k: but for the iterators | 12:27 |
| @sonney2k | just do SG_NOT_IMPLEMENTED | 12:27 |
| van51 | sonney2k: ok | 12:27 |
| van51 | sonney2k: although we could iterate just the sparsevector there | 12:28 |
| van51 | sonney2k: but I remember that the iterator is seldom used | 12:28 |
| van51 | sonney2k: also, how important is the dot() method? | 12:29 |
| van51 | sonney2k: should I also remove the converter from there? | 12:29 |
| @sonney2k | van51, sufficient as is | 12:30 |
| van51 | sonney2k: ok then | 12:30 |
| van51 | sonney2k: I'll update the PR soon and start working on a unit test after that | 12:30 |
| @sonney2k | van51, the iterator was intended for L1 methods | 12:31 |
| @sonney2k | van51, yeah make a toy example give reasonable results and compare to the converter | 12:31 |
| van51 | sonney2k: ok! I'll let you know how it goes | 12:32 |

| van51 | sonney2k: I realize that reviewing so many PRs and stuff may be a bit too much work for you | 12:53 |
| van51 | sonney2k: should I ask Olivier and Benoit to start reviewing my PRs, as well? | 12:53 |

| lisitsyn | gsomix: good | 20:04 |
| @sonney2k | gsomix, hey there! | 20:19 |
| gsomix | sonney2k, hey. | 20:19 |

| @sonney2k | gsomix, a village! | 20:27 |
| @sonney2k | ... with internet! | 20:27 |
| @sonney2k | van51, alright what is the status? | 20:28 |
| gsomix | sonney2k, not village, science city with MIPT. http://phystech.edu/ | 20:28 |

| van51 | sonney2k: it's going pretty good I think | 20:34 |
| van51 | sonney2k: if you don't find something wrong with that's pushed already I just have to finish a unit test case | 20:35 |
| van51 | sonney2k: and I'll get started on an example | 20:35 |
| @sonney2k | van51, feedback send | 20:43 |
| @sonney2k | fix it and I can merge | 20:43 |
| @sonney2k | gsomix, alright so now you have time right? | 20:44 |
| van51 | sonney2k: cool, thank you | 20:44 |
| @sonney2k | gsomix, if so then please finish of your first PR.. add tests! and use van51's *Tokenizer classes! | 20:44 |
| gsomix | sonney2k, yep. now getting familiar with gmock and unit-tests. | 20:46 |
| gsomix | sonney2k, Tokenizer for what? | 20:47 |
| @sonney2k | gsomix, string splitting | 20:48 |
| gsomix | sonney2k, for LineReader and CircularBuffer? or for further readers? | 20:48 |
| @sonney2k | gsomix, for the ascii based readers it makes sense. also for .csv splitting etc | 20:52 |
| gsomix | sonney2k, ah, ok. it might be very useful. I will look into the van51's code. | 20:53 |
| @sonney2k | gsomix, alright so do the tests & get your PR ready then lets talk again :) | 21:00 |
| gsomix | sonney2k, ok | 21:01 |

| pickle27 | hey guys | 22:30 |
| pickle27 | I've got a weird bug that I haven't been able to get for a while | 22:30 |
| pickle27 | I have an eigen map that isn't working and is causing a malloc memory corruption | 22:31 |
| pickle27 | its wierd because I create an SGMatrix create a map on it, perform some math, all of which is fine | 22:31 |
| pickle27 | then I pass the SGMatrix to a function and its the eigen map inside the func which fails | 22:32 |
| pickle27 | the SGMatrix is fine though I just printed it | 22:32 |
| pickle27 | iglesiasg: lisitsyn ^ | 22:32 |
| pickle27 | any ideas? | 22:33 |
| lisitsyn | pickle27: hey | 22:33 |
| lisitsyn | can't say anything specific | 22:33 |
| lisitsyn | lets see code ;) | 22:33 |
| lisitsyn | well actually | 22:34 |
| lisitsyn | valgrind detects such things - may be we can check its output too | 22:34 |
| pickle27 | here is the code | 22:35 |
| pickle27 | http://pastebin.com/yuzxDfHP | 22:35 |
| pickle27 | um | 22:37 |
| pickle27 | so when using valgrind it works .. | 22:37 |
| pickle27 | something wierd is up because when I save the matrix to file it also worked | 22:37 |
| lisitsyn | uhh | 22:38 |
| lisitsyn | pickle27: may be remove references here | 22:38 |
| lisitsyn | SGMatrix<float64_t> tdsep(SGMatrix<float64_t> &x, SGVector<float64_t> &sel) | 22:38 |
| lisitsyn | you don't get real advantage here but it may be unsafe | 22:39 |
| lisitsyn | it shouldn't though | 22:39 |
| pickle27 | okay | 22:39 |
| pickle27 | I think I only added then to try and fix this | 22:39 |
| pickle27 | with valgrind my the map prints but then the program stalls | 22:42 |
| pickle27 | yeah this is weird, now that I can run this code (using valrind) I was able to debug the rest of it and now valgrind says no errors | 22:49 |
| pickle27 | well nvm it says no leaks but there looks like some errors | 22:50 |
| lisitsyn | pickle27: I see no reason to fail we need to force it to fail somehow | 22:50 |
| lisitsyn | pickle27: it is not reference thing I am sure | 22:51 |
| lisitsyn | pickle27: try to reproduce it under valgrind, its output could tell a lot | 22:52 |
| pickle27 | found one thing | 22:53 |
| pickle27 | lisitsyn: my SGVector was too small, silly mistake | 22:53 |
| lisitsyn | ohh yes | 22:53 |
| lisitsyn | 4 vs 3 | 22:53 |
| pickle27 | huh | 22:54 |
| pickle27 | lisitsyn: that might have been it | 22:54 |
| pickle27 | lisitsyn: strange how it manifested | 22:54 |
| pickle27 | lisitsyn: cause yeah it runs now | 22:54 |
| pickle27 | thanks! I never think to use valgrind but its pretty handy | 22:57 |
| lisitsyn | pickle27: always use it when meet segfault ;) | 22:58 |
