| CIA-18 | shogun: Sergey Lisitsyn master * r916983d / (4 files in 2 dirs): Made SGSparseVector inherited from SGReferencedData - http://git.io/QOct9A | 12:56 |
|---|---|---|
| blackburn | sonney2k: ping | 14:07 |
| blackburn | pluskid: around? | 14:07 |
| pluskid | blackburn: yeah | 14:07 |
| blackburn | pluskid: are you familiar with sgvector, etc? | 14:07 |
| pluskid | nope | 14:08 |
| blackburn | рьь | 14:08 |
| blackburn | hmm | 14:08 |
| pluskid | strange characters :D | 14:08 |
| blackburn | do you remember we did some SGReferencedData class here? | 14:08 |
| blackburn | russian | 14:08 |
| pluskid | yeah, I remember | 14:08 |
| blackburn | I have general C++ problem | 14:08 |
| blackburn | we overrided operator= here | 14:08 |
| pluskid | then what's the problem? | 14:09 |
| blackburn | and I need array of sparsevectors (inherited from sgreferenceddata) | 14:09 |
| blackburn | when I allocate it - it contains some crap | 14:09 |
| blackburn | and operator= fails because object is not initialized | 14:09 |
| pluskid | how do you allocate an object without init it? | 14:10 |
| blackburn | SG_MALLOC | 14:10 |
| pluskid | the constructor should init the object properly | 14:10 |
| pluskid | oh, if you use SG_MALLOC | 14:10 |
| blackburn | yeah.. | 14:10 |
| pluskid | then I'm afraid you have to manually call the constructors | 14:10 |
| blackburn | probably new should be here | 14:10 |
| pluskid | you can use "inplace new" to call the constructors on pre-allocated memory | 14:11 |
| pluskid | or is it called "placement new"? I cannot remember correctly | 14:11 |
| blackburn | hmm? | 14:11 |
| pluskid | the syntax is this | 14:11 |
| blackburn | does it require to use X**? | 14:11 |
| blackburn | I have X* array | 14:11 |
| pluskid | new(addr) T(param); | 14:12 |
| blackburn | wow | 14:12 |
| pluskid | where addr is the address of the memory you allocated for T | 14:12 |
| blackburn | I didn't know about it | 14:13 |
| pluskid | it is rarely used | 14:13 |
| pluskid | when you need to use this, remember to manually call the destructors before SG_UNREF | 14:13 |
| pluskid | there seems no special syntax for calling destructors, just call them like normal functions: addr->~T() | 14:14 |
| blackburn | yeah | 14:14 |
| blackburn | pluskid: can it be just new(ptr) class? | 14:15 |
| blackburn | without left part | 14:15 |
| pluskid | yeah | 14:15 |
| pluskid | left part? | 14:15 |
| blackburn | class* x = new(ptr) class | 14:15 |
| blackburn | yeah it can be | 14:15 |
| blackburn | just tried | 14:16 |
| pluskid | :D | 14:17 |
| blackburn | uhh | 14:17 |
| blackburn | destruction could be a problem | 14:17 |
| pluskid | why? | 14:17 |
| blackburn | ah no | 14:17 |
| blackburn | pluskid: did you try shareboost already? | 14:18 |
| blackburn | they claim pretty cool performance | 14:18 |
| pluskid | I only tried on toy data | 14:18 |
| pluskid | to see the training error | 14:18 |
| pluskid | ~70% with 10 features | 14:18 |
| pluskid | haven't evaluated the test error yet | 14:19 |
| blackburn | try on MNIST | 14:19 |
| blackburn | most interesting data for that I think | 14:19 |
| pluskid | ah, yeah | 14:19 |
| pluskid | my poor laptop~~~ | 14:19 |
| blackburn | buy new ;) | 14:20 |
| blackburn | I am going to buy new one next week | 14:20 |
| pluskid | cool, what is that? | 14:20 |
| blackburn | samsung np530 | 14:20 |
| blackburn | with 128gb ssd and i5 cpu | 14:20 |
| pluskid | wow | 14:20 |
| blackburn | I am also going to install additional 4gb ram | 14:20 |
| blackburn | so would have 8 gb of ram | 14:21 |
| pluskid | and the appearance looks cool, too! | 14:21 |
| blackburn | yeah just like macbook air but much cheapier | 14:22 |

| @sonney2k | blackburn, welcome the new server :D | 21:33 |
| puffin444 | New server? | 21:36 |
| @sonney2k | puffin444, shogun-toolbox is now running on a quad-core dedicated server | 21:38 |
| puffin444 | the irc server? what server? | 21:39 |
| puffin444 | The webpage? | 21:39 |
| @sonney2k | puffin444, website, buildbot, etc | 21:39 |
| @sonney2k | 100Mbit connection | 21:39 |
| @sonney2k | 1 TB harddrive | 21:39 |
| puffin444 | nice! | 21:39 |
| blackburn | sonney2k: cool | 21:39 |
| puffin444 | Hey just a question: What do you guys think about solid state hds? | 21:40 |
| @sonney2k | they are expensive :D | 21:40 |
| blackburn | I'm going to buy a notebook with ssd on tuesday | 21:40 |
| puffin444 | My box may joint laptop heaven by the end of next year. Just wondered if you had any experience with ssds | 21:41 |
| puffin444 | *join | 21:42 |
| blackburn | I'll have some next week | 21:42 |
| @sonney2k | puffin444, my mac has one | 21:42 |
| @sonney2k | but it is probably too old | 21:42 |
| puffin444 | Do you think they are worth it? | 21:42 |
| blackburn | puffin444: what is cost of macbook air in usa? | 21:43 |
| @sonney2k | puffin444, mine is a bit slow when compiling | 21:43 |
| blackburn | sonney2k: do you have two drives in there? | 21:44 |
| @sonney2k | so compiling with >1 CPU is slow | 21:44 |
| puffin444 | A quick google such suggests they range from 600-1600 american dollars | 21:44 |
| puffin444 | I have two drives, dual core. | 21:44 |
| @sonney2k | blackburn, I replaced the useless dvd drive with a 1 TB hd | 21:45 |
| blackburn | sonney2k: cool | 21:45 |
| blackburn | didn't know it is possible | 21:45 |
| blackburn | do they provide SATA for dvd drive? | 21:45 |
| @sonney2k | all sata yes | 21:46 |
| blackburn | crazy | 21:46 |
| @sonney2k | but recall my machine is a bit old now | 21:46 |
| blackburn | however useless | 21:46 |
| @sonney2k | 4 (?) years | 21:46 |
| blackburn | 4 years and has ssd? | 21:46 |
| blackburn | 64gb? | 21:46 |
| @sonney2k | 512 | 21:46 |
| blackburn | 512gb ssd?? | 21:46 |
| @sonney2k | y | 21:46 |
| blackburn | ?!! | 21:46 |
| blackburn | how can that be | 21:47 |
| blackburn | :) | 21:47 |
| blackburn | it was very expensive 4 years before I guess | 21:48 |
| @sonney2k | err 256GB | 21:48 |
| @sonney2k | sry | 21:48 |
| blackburn | yeah.. 256 is very expensive still | 21:48 |
| blackburn | but 512 is nearly unavailable | 21:49 |
| blackburn | sonney2k: do you have 17"? | 21:49 |
| blackburn | or 15.6" one? | 21:49 |
| puffin444 | Does it boot up in ten seconds? | 21:50 |
| blackburn | yeah I'm interested too | 21:51 |
| blackburn | sonney2k: ah btw did you optimize your debian for SSDs? | 21:51 |
| blackburn | google told me there are some options | 21:51 |
| blackburn | to make experience better | 21:51 |
| blackburn | puffin444: macbook is more expensive there than in usa:( | 21:53 |
| puffin444 | :( | 21:54 |
| blackburn | I would buy it for 1.2K$ for sure I think | 21:55 |
| blackburn | puffin444: I am going to buy 5 series samsung | 21:56 |
| blackburn | should be cool still | 21:56 |
| blackburn | :) | 21:56 |
| blackburn | puffin444: do you have some old box? | 21:57 |
| @sonney2k | puffin444, what ssd's are good at is low latency | 21:57 |
| @sonney2k | so basically no more seeking | 21:57 |
| @sonney2k | this really speeds up starting of apps | 21:58 |
| puffin444 | I guess it depends on your perspective. I have an HP HDX dragon from 2008. She has served me well, but she is showing her age. | 21:58 |
| puffin444 | The keys are falling off, lots of the button don't work any. No more battery. It weights 20 lbs or ~10 kilos | 21:59 |
| puffin444 | *any more | 21:59 |
| blackburn | ~10 kg??! | 21:59 |
| puffin444 | yes. | 21:59 |
| blackburn | really | 22:00 |
| blackburn | ? | 22:00 |
| blackburn | :D | 22:00 |
| blackburn | you should love new ultrabooks | 22:00 |
| blackburn | with weight sth like 1.1-1.5 kg | 22:00 |
| blackburn | puffin444: I broke keys in my notebook two times - shopped new ones at ebay | 22:01 |
| puffin444 | hmmm... may I should do that. | 22:01 |
| @sonney2k | blackburn, how old is yours? | 22:01 |
| blackburn | sonney2k: jan of 2010 | 22:01 |
| blackburn | very young | 22:02 |
| blackburn | but I am pretty inaccurate hehe | 22:02 |
| @sonney2k | I always had mine for 4-5 years | 22:02 |
| puffin444 | Here's a description: http://www.pcmag.com/article2/0,2817,2127420,00.asp | 22:03 |
| blackburn | I am going to give this one to my parents and enjoy faster and lighter | 22:03 |
| puffin444 | It's more like 7kg | 22:03 |
| blackburn | 20"?? | 22:03 |
| blackburn | omfg | 22:03 |
| puffin444 | yes | 22:03 |
| blackburn | puffin444: do you carry it? | 22:03 |
| puffin444 | yes. It's good exercise :) | 22:04 |
| puffin444 | Can't really take it into a lecture though. | 22:04 |
| blackburn | I feel myself bad then carrying on mine 2.5 kg notebook + some papers whole day long | 22:04 |
| puffin444 | I strap it on my back sort of like a farmer/ | 22:04 |
| blackburn | it is damn huge | 22:04 |
| blackburn | puffin444: you should get something smaller :D | 22:06 |
| puffin444 | At its prime the battery lasted 45 mins :) | 22:06 |
| @sonney2k | haha | 22:06 |
| blackburn | it is just like some huge TV | 22:06 |
| blackburn | http://www9.pcmag.com/media/images/159275-hp-pavilion-hdx9000-right-angle.jpg | 22:06 |
| blackburn | could be node of some cluster | 22:06 |
| blackburn | puffin444: have you ever broke table with it? | 22:07 |
| blackburn | I am still impressed | 22:08 |
| blackburn | :D | 22:08 |
| @sonney2k | blackburn, any ideas how to fix the build? | 22:08 |
| blackburn | is it broken? | 22:08 |
| puffin444 | No but it was too large for some of the lecture desks | 22:08 |
| blackburn | haha | 22:08 |
| blackburn | professor can lost you behind this book | 22:09 |
| puffin444 | yes. It was a major distraction in the lectures. It has really functioned more like a portable desktop for me. | 22:09 |
| blackburn | sonney2k: what is broken exactly? | 22:10 |
| puffin444 | I got it a year after release at a great price because noone wanted to buy such a large laptop. | 22:14 |
| blackburn | puffin444: anyway I'll tell you my experience with latest SSD | 22:15 |
| blackburn | but it should be great I believe | 22:15 |
| blackburn | latency and speed | 22:15 |
| blackburn | less heat | 22:15 |
| puffin444 | yes please tell me when you get it | 22:16 |
| blackburn | puffin444: this one you have should be very warm guy, right? | 22:18 |
| puffin444 | Yes, and what worries me is that the fans are starting to go out | 22:18 |
| puffin444 | Sounds like a helicopter | 22:19 |
| blackburn | hahah | 22:19 |
| blackburn | yeah I think same engine here | 22:19 |
| puffin444 | It's a tragedy for HP. I can't believe it first sold at that outrageous price in that article. | 22:19 |
| blackburn | 4000??? | 22:22 |
| blackburn | puffin444: what was price for you? | 22:22 |
| blackburn | for 4K one can buy some car | 22:23 |
| blackburn | :D | 22:23 |
| puffin444 | Yes that is rediculous. They slashed it by roughly half, which is still pretty expensive but worth it considering its horsepower | 22:23 |
| puffin444 | No one wanted a tank for laptop. | 22:24 |
| blackburn | puffin444: well probably latest macbook pro has similar power now | 22:25 |
| puffin444 | Yes, and probably at a better price. | 22:25 |
| blackburn | heh right | 22:25 |
| blackburn | but not of bus size | 22:26 |
| blackburn | I consider my 15.6" display as big - feel too close | 22:26 |
| blackburn | however you can split your screen | 22:27 |
| blackburn | and edit 8 files simultaneously | 22:27 |
| blackburn | hehe | 22:27 |
| puffin444 | Yeah the view is nice, and it has doubled as a TV for my dorm. | 22:29 |
| puffin444 | It even comes with a remote | 22:29 |
| blackburn | heh | 22:29 |
| puffin444 | I also can't have it as a carry-on in an airplane. | 22:32 |
| blackburn | lol | 22:32 |
| puffin444 | So it gets beat up with the checked in luggage. I managed to get it on the plane once but I was scared because it exceeds the size and weight restrictions. | 22:32 |
