pickle27 | its 5:21 according to google | 17:22 |
pickle27 | i was trying to figure out whats up too | 17:22 |
pickle27 | can't tell if the dimension reduction talk is over or starting | 17:22 |
pickle27 | also all I hear is a buzz | 17:22 |
vikram360 | same here. | 17:22 |
vikram360 | :) | 17:22 |
pickle27 | well I guess we'll stay tuned | 17:23 |
vikram360 | Looks like other people in the audience are waiting for it too. So I guess it's safe to assume that it's yet to begin :) | 17:23 |
pickle27 | what browser slash OS are you using? | 17:23 |
vikram360 | I hope the audio feedback doesn't continue when it starts | 17:23 |
vikram360 | Win XP/FiF 22 | 17:24 |
vikram360 | And you? | 17:24 |
pickle27 | linux and chrome | 17:24 |
vikram360 | I'm not a dinosaur, FYI. I'm using my home PC which, for my parents' convenience is still on XP. | 17:25 |
vikram360 | I just thought I'd clear that up. | 17:25 |
pickle27 | okay we've got 2 very different setups giving the same result | 17:25 |
pickle27 | haha | 17:25 |
vikram360 | I hope tihs audio feedback doesn't persist when the talk starts | 17:26 |

@wiking | :( | 17:29 |
pickle27 | oh | 17:29 |
pickle27 | so we can't really watch the stream then | 17:29 |
vikram360 | Oh, okay. You guys plan on turning it back on when the session starts, I hope? | 17:30 |
@wiking | yes | 17:30 |
@wiking | within seconds | 17:30 |
pickle27 | ahh kk | 17:30 |
vikram360 | :) | 17:30 |
@wiking | lisitsyn: is talking now | 17:31 |
@wiking | if u have problesm with the audio | 17:31 |
@wiking | let me knwo | 17:31 |
vikram360 | There's a bit of a buzz on there. pickle27 you hear it too? | 17:32 |
vikram360 | It's not too bad though. | 17:32 |
@wiking | yeah unfortunately we have a little bit of static noise :( | 17:32 |
@wiking | we couldn't fix it | 17:32 |
thoralf_ | sonney2k: Some other usability issue is IDE (Eclipse, Netbeans, Slickedit). | 17:32 |
pickle27 | its not too bad | 17:33 |
thoralf_ | sonney2k: The current build configuration is hard to integrate into IDE workflows. | 17:33 |
thoralf_ | sonney2k: Especially that most of the code requires that you have run "(sudo) make install" after "make all". | 17:34 |
@sonney2k | thoralf_, where are you ? | 17:35 |

van51 | gsomix_: hey | 20:03 |
gsomix_ | van51, hey. | 20:03 |
van51 | gsomix_: can I ask you something? | 20:03 |
gsomix_ | yep | 20:03 |
van51 | gsomix_: I was using your LineReader before it was merged | 20:03 |
van51 | gsomix_: to read a binary file that had text delimited by \0 | 20:04 |
van51 | gsomix_: but after the merge it has stopped working | 20:04 |
van51 | gsomix_: actually it is reading stuff but it stops prematurely | 20:04 |
van51 | gsomix_: I had the same problem with using basic c++ I/O | 20:04 |
van51 | gsomix_: do you have any suggestion? or could you tell me what did you change? | 20:04 |
gsomix_ | van51, hm. can you send me your code and text file? I'll check. | 20:05 |
van51 | gsomix_: give me a moment to cut a bit of the file because it's huge :P | 20:06 |
gsomix_ | ok | 20:06 |
gsomix_ | >> before it was merged | hipster-programmer | 20:12 |
van51 | gsomix_: haha | 20:14 |
van51 | gsomix_: here is the file : https://dl.dropboxusercontent.com/u/23851310/webspam_train_first200.txt | 20:14 |
van51 | gsomix_: it's actually binary | 20:14 |
van51 | gsomix_: and here is my code | 20:14 |
van51 | https://gist.github.com/van51/5938097 | 20:14 |
gsomix_ | van51, ok. | 20:18 |
-!- gsomix_ is now known as gsomix | 20:18 | |
van51 | gsomix: thx for offering to look at it | 20:19 |
van51 | gsomix: but don't spend too much time on it | 20:19 |
van51 | gsomix: I'm sure you have other stuff to do as well :) | 20:19 |
van51 | gsomix: I was just wondering if you could think of something | 20:19 |

gsomix | van51, hey. how many parts are delimited by \0 in your file? | 21:15 |
van51 | gsomix: in the one I send you I think there is only one \0 | 21:15 |
gsomix | van51, and where reading stops? | 21:17 |
van51 | gsomix: it stops at "<area shape="RECT" coords="7,86,110,100"" | 21:17 |
-!- thoralf [~thoralf@91.102.9.98] has quit [Ping timeout: 276 seconds] | 21:17 | |
van51 | gsomix: while it should have stopped at a </html> | 21:17 |
gsomix | van51, it works fine for me. I just replace SG_SPRINT("%s\n") by for (bla_bla) { SG_SPRINT("%c"); }. | 21:20 |
gsomix | do I miss something? | 21:20 |
van51 | gsomix: give me a moment to check | 21:20 |
van51 | gsomix: hmm indeed | 21:21 |
van51 | gsomix: I was just getting a seg fault in the beginning and I assumed it was from there | 21:21 |
van51 | gsomix: and the print statement didn't help :) | 21:22 |
gsomix | btw can you use has_next_line() for checking? I found some bad behavior in my code - need to fix. | 21:23 |
van51 | gsomix: ok I'll use it | 21:24 |
van51 | gsomix: thanks for your time :) | 21:24 |
van51 | gsomix: what was the bad behavior btw? | 21:26 |
gsomix | van51, unlimited decrease the internal counter in CircularBuffer when you try read nothing. nevermind. :) | 21:27 |
gsomix | just use has_next_line, I'll fix this thing little late. | 21:27 |
gsomix | *later | 21:28 |
van51 | gsomix: cool | 21:28 |
gsomix | >> thanks for your time | now I need YOUR time. a little. I'm writing CSV reader now. | 21:29 |
gsomix | how do you think what's better solution: templated CSV reader class with SGVector<T> readVector() and SGMatrix<T> readMatrix() methods | 21:30 |
gsomix | or not templated class with many methods like SGVector<int32_t> readIntVector(), SGVector<int64_t> readLongIntVector()... | 21:31 |
gsomix | and so on | 21:31 |
gsomix | ? | 21:31 |
van51 | gsomix: hmm | 21:31 |
van51 | gsomix: I think I would prefer the first one | 21:32 |
van51 | gsomix: is there a change the csv file could have vectors of different types? | 21:32 |
van51 | chance* | 21:32 |
gsomix | yeah, maybe. I still didn't figured out how work with it. btw quoting is pain with only DelimiterTokenizer. | 21:35 |
gsomix | now I want just write reader for one-typed csv files | 21:35 |
van51 | gsomix: what exactly is pain? | 21:36 |
van51 | gsomix: reading between quotes? | 21:36 |
gsomix | yeah | 21:38 |
gsomix | I think I should split line with " delimiter first, and then analyze each token | 21:39 |
van51 | gsomix: you use multiple delimiters? | 21:40 |
gsomix | nope | 21:40 |
van51 | gsomix: then repeated calls to get next_token wouldn't give you the thingy between quotes? | 21:42 |
gsomix | there are some exotic examples, like delimiters and \n between quotes, that shouldn't be delimiters because it's quoted. | 21:43 |
van51 | gsomix: aaah I see | 21:44 |
van51 | gsomix: yeah that would be an issue | 21:44 |
gsomix | but I don't really think this is common for ML data sets. need consult with sonney2k | 21:44 |
van51 | gsomix: I don't know about that, but if it's required I could add support for it in the delimiter class | 21:46 |
gsomix | van51, I don't think that it's really needed. | 21:46 |
gsomix | van51, ok, thanks for advice. I should continue my work. | 21:47 |
gsomix | ah, and cool video at the end! http://www.youtube.com/watch?v=eGimzB5QM1M | 21:48 |
gsomix | :) | 21:48 |
van51 | gsomix: I hadn't even considered escaped delimiters | 21:48 |
van51 | gsomix: maybe it's something that needs to be supported | 21:48 |
van51 | gsomix: anyway, discuss it with sonney2k and let me know :) | 21:48 |
van51 | gsomix: nice vid :) | 21:50 |
gsomix | yeah, SpaceX is great aerospace company. I would work in it, but I'm not rocket scientist, huh. | 21:54 |
van51 | gsomix: you could learn how to handle a camera :p | 21:54 |
gsomix | hmmm... | 21:55 |
