| lisitsyn | thoralf: hey | 00:47 |
|---|---|---|
| thoralf | Hey lisitsyn | 00:47 |
| lisitsyn | thoralf: I see some singleton issue :) | 00:47 |
| thoralf | Yeah. :) | 00:48 |
| thoralf | I opened the battle. | 00:48 |
| thoralf | Wanna join? ;) | 00:48 |
| lisitsyn | thoralf: actually we can go ahead and just make shogun itself instantiable | 00:49 |
| lisitsyn | run multiple shoguns :D | 00:49 |
| thoralf | lol | 00:49 |
| thoralf | Yeah, that's true. | 00:49 |
| lisitsyn | well that's natural extension | 00:49 |
| thoralf | We would loose that. | 00:49 |
| lisitsyn | everything that's single will get multiple | 00:49 |
| lisitsyn | somebody wise should have said that before I bet | 00:49 |
| lisitsyn | like karl marx haha | 00:50 |
| thoralf | lol | 00:50 |
| lisitsyn | OpenSSL is written by monkeys https://www.peereboom.us/assl/assl/html/openssl.html | 00:51 |
| lisitsyn | can't resist to share | 00:51 |
| thoralf | Hahah. | 00:51 |
| lisitsyn | ah and if anybody is interested I dumped my c++ssy brain again | 00:53 |
| lisitsyn | http://sergey.lisitsyn.me/2014/04/08/actions-with-raii/ | 00:53 |
| thoralf | lisitsyn: The monkey-story is great. | 01:00 |
| thoralf | tl;sr; | 01:00 |
| lisitsyn | thoralf: yeah they sucked a big time | 01:02 |
| lisitsyn | our bugs lead to wrong nothing | 01:03 |
| lisitsyn | but their bugs are like important :) | 01:03 |
| thoralf | Yeah. :) | 01:03 |
| thoralf | But really, I still don't know why every object needs to have all this crap. I never used serialization *or* model-selection *or* parameter framework to compare objects. | 01:04 |
| lisitsyn | thoralf: they should have one thing | 01:04 |
| lisitsyn | shogun instance ;) | 01:04 |
| lisitsyn | which has vresion parallel etc | 01:04 |
| thoralf | I was about to fork shogun and rip it of. | 01:05 |
| lisitsyn | thoralf: it is a known syndrome | 01:05 |
| thoralf | Or making it de-configurable by -DDISABLE_PARAMETER and -DDISABLE_MODEL_SELECTION. | 01:05 |
| thoralf | Yeah. | 01:05 |
| thoralf | I decided against forking, because I want better code... not worse. ;) | 01:05 |
| lisitsyn | it is called shogun forking disorder | 01:06 |
| lisitsyn | :D | 01:06 |
| lisitsyn | sometimes referred as shogunophrenia | 01:06 |
| thoralf | ophrenia? | 01:07 |
| thoralf | You're suffering this as well? | 01:07 |
| lisitsyn | well I am mentally disabled since I got ill | 01:07 |
| lisitsyn | :D | 01:07 |
| lisitsyn | sometimes I walk into walls | 01:08 |
| lisitsyn | ok actually yes everybody in shogun wanted to rewrite this f'ing s't | 01:08 |
| thoralf | Hmm. So why are we (everybody except me) putting more sh't in instead of removing it? | 01:09 |
| thoralf | Well, wiking is good in consolidating I guess. | 01:10 |
| lisitsyn | have you seen my commits lately? ;) | 01:10 |
| thoralf | And cleaning up. | 01:10 |
| thoralf | lisitsyn: You're still committing? | 01:10 |
| thoralf | I thought you're just hanging up here because you're used to. :D | 01:10 |
| lisitsyn | not really :D | 01:10 |
| lisitsyn | not really to both | 01:11 |
| thoralf | Are you using shogun somewhere? | 01:11 |
| lisitsyn | no :) | 01:11 |
| lisitsyn | that's a major point | 01:11 |
| thoralf | lol | 01:11 |
| lisitsyn | thoralf: I have nothing to use it for | 01:12 |
| lisitsyn | thoralf: but I am not just hanging up I am just sloooooow | 01:12 |
| thoralf | That's a bad starting point for discussing improvements. ;) | 01:12 |
| lisitsyn | I am sloowly getting to some solution for modular shogun | 01:13 |
| lisitsyn | that's what I devote my life for hahah | 01:13 |
| lisitsyn | thoralf: I use it pretty rarely but nothing advanced | 01:13 |
| lisitsyn | well though I have some vague understanding what our users need | 01:14 |
| lisitsyn | so you are mostly right ;) | 01:14 |
| thoralf | :D | 01:15 |
| thoralf | So does it mean you're joining the battle to improve something that has no effect on you? ;) | 01:15 |
| lisitsyn | thoralf: I am pretty far away from all the battles | 01:15 |
| lisitsyn | thoralf: well I have some idea how software should look like - that's what I am based on | 01:16 |
| thoralf | A good-code based life form? :) | 01:17 |
| thoralf | I know carbon-based life forms... they don't perform well. | 01:17 |
| lisitsyn | thoralf: I am not sure what you mean ;) I don't put my opinion on things that affect user experience | 01:19 |
| lisitsyn | if someone says X would be better I would believe that | 01:19 |
| thoralf | Hmm. Interesting approach. | 01:20 |
| thoralf | Saves a lot of hassle. | 01:20 |
| lisitsyn | so I believe I am not that harmful ;) | 01:20 |

| lisitsyn | we need kaggle team | 12:54 |
| lisitsyn | :D | 12:54 |
| lisitsyn | HeikoS: wiking: besser82: lambday: sonne|work: we need kaggle team! | 12:54 |
| lambday | lisitsyn: who's competing? :-o | 12:55 |
| wiking | lisitsyn: for which task? | 12:56 |
| lisitsyn | wiking: any | 12:57 |
| wiking | https://www.kaggle.com/c/risky-business | 12:57 |
| wiking | ? | 12:57 |
| wiking | :) | 12:57 |
| wiking | we cannot do that ;P | 12:58 |
| lisitsyn | well small steps | 12:58 |
| lisitsyn | :D | 12:58 |
| lisitsyn | we can just start from these simple test tasks | 12:58 |
| wiking | https://www.kaggle.com/c/allstate-purchase-prediction-challenge | 12:58 |
| lisitsyn | that's the way we can improve our API | 12:58 |
| HeikoS1 | lisitsyn: I agree :) | 13:00 |
| wiking | lisitsyn: let's start a python notebook ;) | 13:00 |
| wiking | *ipython | 13:00 |
| wiking | for the task | 13:01 |
| wiking | ) | 13:01 |
| wiking | that would be the best i think | 13:01 |
| HeikoS1 | wiking: I agree :) | 13:01 |
| wiking | lisitsyn: new repo? | 13:04 |
| wiking | shogun-kaggle ? | 13:04 |
| lisitsyn | yes | 13:04 |
| lambday | sounds great! | 13:05 |
| lisitsyn | let me create that | 13:05 |
| lisitsyn | https://github.com/shogun-toolbox/shogun-kaggle | 13:06 |
| lisitsyn | HeikoS: wiking: besser82: lambday: sonne|work: ok and another thing - we have to get distributed | 13:06 |
| wiking | lisitsyn: hah u were faster :) | 13:06 |
| wiking | lisitsyn: what do u mean? :) | 13:06 |
| wiking | lisitsyn: btw we would need a team as well | 13:07 |
| wiking | i mean on kaggle | 13:07 |
| lisitsyn | yes | 13:07 |
| wiking | i have a kaggle account | 13:07 |
| wiking | anybody else? | 13:07 |
| lisitsyn | I have | 13:07 |
| lambday | I do | 13:07 |
| lisitsyn | hmm guys | 13:07 |
| lisitsyn | just an idea | 13:07 |
| lisitsyn | can we create some roles in our team? | 13:07 |
| wiking | like? | 13:08 |
| lisitsyn | hmm e.g. HeikoS knows about X | 13:08 |
| lisitsyn | and you wiking know about Y | 13:08 |
| lisitsyn | so we delegate responsibilitie | 13:08 |
| lisitsyn | I have vague idea but want to share | 13:08 |
| lisitsyn | :D | 13:08 |
| wiking | k | 13:09 |
| lisitsyn | wiking: ok actually may be we should denote maintainers for modules | 13:09 |
| lisitsyn | what do you think about that? | 13:09 |
| wiking | sounds like a plan | 13:09 |
| wiking | btw anybody has a fucking dashboard on kaggle? ) | 13:10 |
| lisitsyn | I mean I should be responsible for multiclass things | 13:10 |
| lisitsyn | and everybody should kick me to care about that | 13:10 |
| wiking | yeah that'd be good | 13:10 |
| lisitsyn | :D | 13:10 |
| lisitsyn | okay may be we can go on later | 13:10 |
| wiking | so that we dont have scary merges | 13:10 |
| lisitsyn | I have no clue what's the dashboard on kaggle | 13:10 |
| wiking | me neither | 13:11 |
| wiking | ok fuck | 13:12 |
| wiking | i've found it :D | 13:12 |
| wiking | anybody care to give me his kaggle account? | 13:13 |
| wiking | or rather the email addr u use for kaggle? | 13:14 |
| lambday | wiking: mine is heavensdevil6909@gmail.com | 13:14 |
| lambday | rahul-de is the username | 13:14 |
| wiking | lisitsyn: ping? | 13:14 |
| lisitsyn | my login is no-idea | 13:14 |
| lisitsyn | just a sec | 13:14 |
| wiking | lisitsyn: email u used for kaggle | 13:14 |
| lisitsyn | I feel idiot when clicking forgot username | 13:15 |
| lisitsyn | :D | 13:15 |
| wiking | lambday: u should receive an email | 13:15 |
| lambday | got it | 13:15 |
| lisitsyn | wiking: lisitsyn.s.o@gmail.com | 13:15 |
| wiking | lisitsyn: sent the invite | 13:15 |
| wiking | seems we cannot have permanent teams | 13:15 |
| wiking | only per competition teams | 13:15 |
| lisitsyn | oh | 13:16 |
| lisitsyn | really? | 13:16 |
| wiking | lisitsyn: yeah seems like | 13:16 |
| lambday | holy crap that's a long list of rules | 13:16 |
| lisitsyn | sucks | 13:16 |
| wiking | heheh accept it | 13:16 |
| wiking | :) | 13:16 |
| lambday | yeah did :D | 13:16 |
| wiking | ok so now we have a team | 13:16 |
| wiking | and we can do submissions | 13:16 |
| lambday | only the outputs are to be submitted iirc | 13:18 |
| wiking | yep | 13:18 |
| wiking | so now the task is pretty easy | 13:18 |
| lisitsyn | yeah win it | 13:18 |
| lisitsyn | that's the easy part | 13:18 |
| lambday | $50k | 13:18 |
| wiking | i mean read in file | 13:18 |
| wiking | and the output file creator | 13:18 |
| wiking | that's like step -1 | 13:18 |
| lisitsyn | ... | 13:18 |
| lisitsyn | profit | 13:18 |
| lisitsyn | :D | 13:18 |
| wiking | :D | 13:18 |
| wiking | and then we'll see the rest | 13:18 |
| wiking | btw any ideas of the structure for the repo ? | 13:19 |
| wiking | like each competition a separate directory? | 13:19 |
| lisitsyn | competition-name/... | 13:19 |
| lisitsyn | yeah | 13:19 |
| wiking | and the data should be always like | 13:19 |
| wiking | competiton-name/data directory | 13:19 |
| wiking | since we are not allowed to distribute the data | 13:19 |
| lisitsyn | uhmm github will kill us | 13:20 |
| lisitsyn | if we put data | 13:20 |
| wiking | so everybody has to download that for ourselves | 13:20 |
| lisitsyn | yeah | 13:20 |
| wiking | lisitsyn: nana we are not allowed i think | 13:20 |
| lambday | btw why notebook? I mean the data is usually *H-U-G-E*.. | 13:20 |
| lisitsyn | wiking: yeah we are not allowed as well | 13:20 |
| wiking | lambday: well the notebook was just for having a great way to present our solution already | 13:20 |
| wiking | so it's not just messy code | 13:20 |
| lambday | alrighty | 13:20 |
| wiking | but somebody can right away like check the whole solution | 13:20 |
| wiking | of course it'll make things much more complicated | 13:21 |
| wiking | so maybe it's not the good idea | 13:21 |
| wiking | as honestly coding and doing experiments with a notebook | 13:21 |
| wiking | i think is a bit pain... | 13:21 |
| lambday | we need to submit multiple solutions with different approaches.. | 13:22 |
| lambday | and the best one is our score | 13:22 |
| wiking | lambday: well that's easy | 13:22 |
| wiking | random() | 13:22 |
| wiking | :D | 13:22 |
| wiking | that'll put us somewhere on the leaderboard already :PPP | 13:22 |
| lambday | lol... | 13:23 |
| lisitsyn | ah guys | 13:23 |
| lisitsyn | language? | 13:23 |
| lambday | doesn't matter | 13:23 |
| wiking | yeah that's what i was about to ask | 13:23 |
| lisitsyn | hmm matters | 13:23 |
| wiking | go hardcore and do everything in c++ | 13:23 |
| lisitsyn | hahah | 13:23 |
| lisitsyn | no | 13:23 |
| wiking | or be more subtle and python | 13:23 |
| wiking | ? | 13:23 |
| lisitsyn | python | 13:23 |
| wiking | yeah i'm for python as well | 13:23 |
| lambday | will take ages to process GBs of data | 13:23 |
| wiking | lambday: where do u see the gigs of data? | 13:24 |
| lisitsyn | yeah | 13:24 |
| lisitsyn | 10 mb | 13:24 |
| lisitsyn | :D | 13:24 |
| lisitsyn | 5.63mb train | 13:24 |
| lisitsyn | 2.02 test | 13:24 |
| lambday | last competition I participated in had 500MB compressed data | 13:24 |
| lisitsyn | that's not big data | 13:24 |
| lisitsyn | :D | 13:24 |
| lambday | this one is easy then :D | 13:24 |
| lambday | python +1 | 13:24 |
| wiking | l-rw-r--r-- 1 wiking staff 46M Feb 18 09:37 train.csv | 13:25 |
| lisitsyn | oops | 13:25 |
| lisitsyn | I told you zip | 13:25 |
| wiking | so the first thing we need to do is fix the readline :))))) | 13:25 |
| lisitsyn | I can start with IO actually | 13:25 |
| HeikoS1 | just talked to dino, who is also interested | 13:25 |
| lisitsyn | tonight | 13:25 |
| lisitsyn | HeikoS1: are you in? | 13:26 |
| -!- sejDino [~rudo@cpc1-dals14-2-0-cust31.hari.cable.virginm.net] has joined #shogun | 13:26 | |
| lisitsyn | hey sejDino | 13:26 |
| wiking | ok please register on kaggle and give me email addr that u used for registering on kaggle.com | 13:26 |
| wiking | so i can invite u guys to the team | 13:26 |
| lambday | sejDino: hi :) | 13:26 |
| HeikoS1 | lisitsyn: yes I would like to join this stuff | 13:26 |
| sejDino | hey! | 13:26 |
| HeikoS1 | good way to make shogun more usable for some more applied things :) | 13:26 |
| lisitsyn | okay employ more guys and we will win | 13:27 |
| lisitsyn | :D | 13:27 |
| wiking | :D | 13:27 |
| HeikoS1 | I guess we will come up with a list of things that would be useful to have and discover loads of bugs ;) | 13:27 |
| lisitsyn | we need a tracker | 13:29 |
| lisitsyn | to distribute tasks and so on | 13:29 |
| lisitsyn | who's up to use github? | 13:29 |
| wiking | lisitsyn: github/issues and create a new label called kaggle? | 13:30 |
| wiking | or since it's a different repo | 13:30 |
| wiking | we can do that there | 13:30 |
| wiking | https://github.com/shogun-toolbox/shogun-kaggle/issues | 13:30 |
| lisitsyn | created milestone | 13:30 |
| lisitsyn | and label | 13:30 |
| wiking | and if we need to fix a bug within shogun because we found it because of kaggle task we can still label it kaggle | 13:31 |
| wiking | so that we know what might be a priority bug to fix | 13:31 |
| wiking | and for later statistics | 13:31 |
| wiking | to see how many bugs we actually found/fixed because of kaggling | 13:31 |
| wiking | lisitsyn: sounds like a plan | 13:31 |
| sejDino | so is the plan to go for allstate challenge or risky business or both? :) | 13:32 |
| wiking | sejDino: we cannod to risky business | 13:32 |
| wiking | as it's only for master members of kaggle | 13:32 |
| wiking | and none of us has that XP points on kaggle :P | 13:33 |
| wiking | sejDino: but we can do other 'educational' task as well | 13:33 |
| sejDino | I see - oh, well - now we'll start building those XP pts quickly :) | 13:33 |
| wiking | just to promote shogun | 13:33 |
| lisitsyn | https://github.com/shogun-toolbox/shogun-kaggle/issues | 13:33 |
| wiking | lisitsyn: is on fire | 13:33 |
| sejDino | that sounds like a good idea as well | 13:33 |
| lisitsyn | https://github.com/shogun-toolbox/shogun-kaggle/issues/2 | 13:34 |
| lisitsyn | dump your mind here | 13:34 |
| lisitsyn | who's up describing the input /output data? | 13:34 |
| lisitsyn | in the #2 | 13:34 |
| lisitsyn | sooo whoo | 13:35 |
| lisitsyn | do we need a cluster? | 13:35 |
| wiking | lisitsyn: no ... worst case we use fatbot :P | 13:36 |
| wiking | teh amount of data is really not so much | 13:36 |
| lisitsyn | wiking: want to describe dataset? | 13:36 |
| wiking | 665250 data/train.csv | 13:36 |
| wiking | -1 because it has header | 13:36 |
| wiking | lisitsyn: yeah sure i'm up for that | 13:36 |
| lisitsyn | wiking: https://github.com/shogun-toolbox/shogun-kaggle/issues/3 | 13:37 |
| lisitsyn | sejDino: HeikoS: HeikoS1: you are scientific guys | 13:38 |
| lisitsyn | so waiting your input https://github.com/shogun-toolbox/shogun-kaggle/issues/2 | 13:38 |
| lisitsyn | ;) | 13:38 |
| HeikoS1 | lisitsyn: happy to do :) Ill talk to sejDino a bit later today and then well give some output | 13:39 |
| lisitsyn | HeikoS: assigned you responsible for this issue ;) | 13:39 |
| sejDino | lisitsyn: yep, will work on it :) | 13:39 |
| lisitsyn | ok that's going much funny now | 13:40 |
| lisitsyn | :D | 13:40 |
| sejDino | it seems like an interesting problem actually - each customer samples a bunch of these "options" and then they pick one of those (or a new one) | 13:41 |
| lisitsyn | HeikoS1: okay lets organize it this way | 13:41 |
| sejDino | so it's not really a standard classification/regression task | 13:41 |
| lisitsyn | we discuss it in #2 | 13:41 |
| lisitsyn | then everything that is worth trying | 13:41 |
| lisitsyn | is forked to a new task | 13:41 |
| lisitsyn | agree? | 13:42 |
| sejDino | lisitsyn: sounds good | 13:42 |
| lisitsyn | sejDino: cool thanks | 13:42 |
| lisitsyn | lambday: mind to start notebook? | 13:43 |
| lisitsyn | or other words | 13:44 |
| lisitsyn | want to be responsible for notebook? | 13:44 |
| lisitsyn | ;) | 13:44 |
| lambday | lisitsyn: what should we start with? | 13:44 |
| lambday | yeah I can do that | 13:44 |
| lisitsyn | lambday: hmm okay actually | 13:44 |
| lisitsyn | you could create some draft | 13:44 |
| lisitsyn | and make sure everybody can work on notebook in one click | 13:45 |
| wiking | lambday: use the template and put it in shogun-kaggle/allstate | 13:45 |
| lisitsyn | so makefile or sth like that | 13:45 |
| wiking | lambday: and u can have the assumption that the data is in shogun-kaggle/allstate/data | 13:45 |
| lisitsyn | I want to organize it that way | 13:45 |
| lisitsyn | so we have some 'library' | 13:45 |
| lisitsyn | that is used in notebook | 13:46 |
| wiking | lisitsyn: yeah | 13:46 |
| lisitsyn | so we can hide some routine things | 13:46 |
| lisitsyn | load_dataset() | 13:46 |
| lisitsyn | that's it | 13:46 |
| wiking | lisitsyn: yeah i think all the .py + ipynb should be in shogun-kaggle/allstate | 13:46 |
| lisitsyn | yes | 13:46 |
| wiking | and then u can from . import load_dataset | 13:46 |
| lisitsyn | okay will be back a bit later | 13:47 |
| wiking | in the notebook | 13:47 |
| lisitsyn | yes | 13:47 |
| wiking | lisitsyn: thing is though | 13:47 |
| wiking | lisitsyn: this dataset is more or less a timeline | 13:47 |
| wiking | lisitsyn: so actually a pandas dataframe would be the best option to store the data ;) | 13:47 |
| wiking | not CFeatures of any kind | 13:48 |
| wiking | although this is just the first thought i had now looking at the dataset | 13:48 |
| wiking | bbl | 13:48 |

| pl8787 | I think add a subclass of CFeatures may solve this problem. Such as CIndexFeatures | 13:53 |
| pl8787 | If CIndexFeatures pass in CCustom::init, we just change the subset of the kernel matrix, and then get_kernel_matrix will return the right value. | 13:55 |

| sunil1337 | lambday: hey! | 21:30 |
| lambday | sunil1337: hi! | 21:31 |
| sunil1337 | lambday: please review https://github.com/sunil1337/shogun/commit/ef30f622df44ab51cb97c4a66c5ea3a673348dfe | 21:31 |
| lambday | sunil1337: checking | 21:32 |
| sunil1337 | lambday: okay! fails at compiling class_list.cpp because we have 3 defs of eigen3 and naive. need a work around there | 21:32 |
| lambday | 3 defs of eigen3 and naive? | 21:33 |
| sunil1337 | lambday: partial specialization they py scripts adds them to class_list.cpp | 21:33 |
| sunil1337 | lambday:*the | 21:33 |
| lambday | sunil1337: you could have just left the sparse thing for now | 21:34 |
| lambday | the code won't be same for dense and sparse | 21:34 |
| lambday | as in, we can't use map | 21:34 |
| sunil1337 | lambday: yeah.. i just called existing sparse_dot for now | 21:34 |
| sunil1337 | lambday: i've commented the problem please take a look | 21:35 |
| lambday | okie | 21:35 |
| lambday | sunil1337: could you please split the definition and declarations? | 21:36 |
| lambday | into separate .h and .cpp | 21:36 |
| lambday | each class - one .h one .cpp | 21:37 |
| sunil1337 | lambday: sure.. | 21:37 |
| wiking | btw u could use macros | 21:37 |
| sunil1337 | wiking: for new calls ? | 21:38 |
| lambday | sunil1337: umm you didn't need to add VectorDotOperator already... first just VectorDotProduct and Eigen3DotProduct which would work independently | 21:39 |
| lambday | then we would add CLinearAlgebra factory class | 21:39 |
| lambday | after that we'll add VectorDotOperator | 21:39 |
| lambday | under LinearOperator interface | 21:39 |
| lambday | this iterative approach makes it easy to find bugs | 21:40 |
| lambday | Naive - we don't really need.. I just added in the gist for demonstration purpose | 21:40 |
| sunil1337 | lambday: okay! :) | 21:40 |
| lambday | this looks good :) | 21:41 |
| lambday | good work :) | 21:41 |
| sunil1337 | lambday: thanks :) naive is already there in existing SGVector class... | 21:41 |
| lambday | but if you could please send patches containing those two first | 21:41 |
| lambday | it would make it so much easier | 21:41 |
| sunil1337 | lambday: will do.. :) | 21:41 |
| lambday | yeah - no one needs a sophisticated interface to do naive things ;) | 21:41 |
| sunil1337 | lambday: :) | 21:42 |
| lambday | sunil1337: we *don't* need to put VectorDotProduct under SGObject | 21:45 |

| thoralf | lisitsyn: Awake? | 22:57 |
| lisitsyn | thoralf: yes | 22:57 |
| thoralf | Hello :) | 22:57 |
| thoralf | I just realized we're having global variables anyway and are just copying them to each object. | 22:57 |
| thoralf | So it does means we cannot have multiple shoguns even right now. | 22:58 |
| thoralf | And the difference between global variables and singletons is artificial for this discussion. ;) | 22:58 |
| lisitsyn | yeah | 23:00 |
| lisitsyn | we have it tied together already | 23:00 |
| thoralf | We're doomed anyway. So let's change it while everybody is sleeping. :D | 23:04 |
| lisitsyn | thoralf: what exactly? | 23:10 |
| lisitsyn | I am completely lost in discussions | 23:10 |
| lisitsyn | :D | 23:10 |
| thoralf | Removing SGIO, Version, Parallel members from CSGObject. | 23:11 |
| lisitsyn | thoralf: want to do that? | 23:12 |
| lisitsyn | ;) | 23:12 |
| thoralf | Wrong question. | 23:13 |
| thoralf | Want to write a ticket for that? :D | 23:13 |
| lisitsyn | ahh students | 23:13 |
| lisitsyn | thoralf: that's the same thing happens at my job | 23:13 |
| lisitsyn | constantly forgetting I have 3 programmers to delegate job | 23:14 |
| lisitsyn | :D | 23:14 |
| thoralf | lisitsyn: To me honest, I'm a bit lost how to improve this "thing" and I want to discuss which options we have (without making it worse by adding another 1000 classes). | 23:15 |
| thoralf | Changing it would only be the technical part. | 23:16 |
| lisitsyn | thoralf: I think making SGContext a singleton first | 23:16 |
| lisitsyn | would work | 23:16 |
| thoralf | I have no concerns about this. | 23:18 |
| thoralf | Putting Version, Parallel, SGIO into it. | 23:18 |
| thoralf | Most functionality on these things is based on macros, so easy to change without touching many classes. | 23:19 |
| lisitsyn | yeah | 23:21 |
| thoralf | And then we would naturally lose the duplication of SG_SINFO/SG_INFO, etc., because everything is depending on the singleton. | 23:21 |
| lisitsyn | uh | 23:22 |
| thoralf | What? Did I miss something? | 23:22 |
| lisitsyn | well if we don't want multiple contexts | 23:22 |
| lisitsyn | it should work | 23:22 |
| lisitsyn | I overlooked the SG_SINFO/SG_INFO thing | 23:22 |
| lisitsyn | thoralf: if we use the singleton in SG_INFO | 23:23 |
| lisitsyn | this member of SGObject makes no sense | 23:23 |
| lisitsyn | won't be used | 23:23 |
| thoralf | Yes. | 23:24 |
| thoralf | So we can remove it. Hooray :) | 23:24 |
| lisitsyn | this denies multiple contexts | 23:25 |
| lisitsyn | I would be ok with multiple contexts | 23:25 |
| lisitsyn | so that's disputable | 23:25 |
| thoralf | Okay, how would it work with multiple contexts? | 23:25 |
| thoralf | Lets say, you have machine1 from context1 and machine2 from context2. How would each machine create a new CLabel of the right context? | 23:26 |
| lisitsyn | we should ask for labels in context | 23:28 |
| lisitsyn | :D | 23:28 |
| lisitsyn | that sounds like a factory | 23:28 |
| thoralf | Yeah. | 23:28 |
| thoralf | Sounds like JavaEE | 23:28 |
| thoralf | CLabels l = context.register(new CLabels); | 23:29 |
| thoralf | vs | 23:29 |
| thoralf | CLabels l = context.getInstanceOf(class CLabels); | 23:29 |
| lisitsyn | thoralf: actually there is a lot of beauty in that :D | 23:32 |
| lisitsyn | makes things really extensible | 23:32 |
| lisitsyn | thoralf: if we go modular | 23:33 |
| lisitsyn | we'd need factories anyway | 23:33 |
| thoralf | Correct me if I'm wrong, but this doesn't make things simpler. ;) | 23:33 |
| lisitsyn | thoralf: this makes things extensible ;) | 23:33 |
| thoralf | Correct me if I'm wrong, but this doesn't make things simpler. ;) | 23:33 |
| thoralf | lol, okay. | 23:34 |
| thoralf | No free lunch. | 23:34 |
| lisitsyn | well the simplest thing is no objects | 23:34 |
| lisitsyn | ;) | 23:34 |
| lisitsyn | but the issue is that we really need factories to go modular | 23:34 |
| lisitsyn | say I wrote SuperSVM | 23:34 |
| lisitsyn | how do I spawn it? | 23:35 |
| lisitsyn | there is no SuperSVM in headers/interfaces | 23:35 |
| lisitsyn | I can only ask for SVM | 23:36 |
| lisitsyn | (effectively) | 23:36 |
| thoralf | Damn. | 23:39 |

| thoralf | You're playing in the opposite team. | 23:39 |
| thoralf | I'm on simplification (white circle on white background) | 23:39 |
| thoralf | You're on, well, you're on maximum extensible. ;) | 23:40 |
| lisitsyn | thoralf: we need plugins | 23:41 |
| lisitsyn | to not wait \infty before it compiles | 23:41 |
| lisitsyn | and to use only what you want :) | 23:41 |
| lisitsyn | plugins are not only about extensibility but to put development on speed | 23:42 |
| thoralf | Hmm. | 23:43 |
| thoralf | But this involves *many* design decisions that haven't been met. For example: simple "data" classes like vectors, matrices, etc. that need to be fast. No need to ask daddy every time you want to create an instance. | 23:44 |
| lisitsyn | but they are not sgobjects, right? | 23:45 |
| thoralf | Hmm. | 23:45 |
| thoralf | Hmm! | 23:45 |
| thoralf | Yes. | 23:45 |
| lisitsyn | I am talking only about sgobjects because they are not lightweight | 23:45 |
| lisitsyn | and never been :) | 23:45 |
| thoralf | I got your point. | 23:47 |
| lisitsyn | okay destination bed | 23:50 |
| thoralf | Good night. | 23:52 |
