@ Home, done for now...and blogged about it!

Home, done for now…and blogged about it! by Caitlin ‘Caity’ Tobias, on Flickr

I seldom make it to the Open Source User Group meeting these days. Today I did today. I don’t have time to write the meeting up. But, there is some interesting information. So, I’ll post the raw log as Oz Linden doesn’t post his meeting chat logs. While I would like it if he did, there are way better things he can do with his time.

Chat Log Text
[2015/03/02 07:03]  Wolfpup (wolfpup.lowenhar): Oz im still having issues with the the new build chain in an OS build environment
[2015/03/02 07:03]  Yuzuru (yuzuru.jewell): Hello, Nalates.
[2015/03/02 07:03]  Nal (nalates.urriah): Hi Yuzuru, everyone
[2015/03/02 07:03]  Oz Linden: what sort of issues, Wolfpup?
[2015/03/02 07:03]  さくら (sakuranoel.fayray): Hello
[2015/03/02 07:04]  Wolfpup (wolfpup.lowenhar): i got my new QuickTime Variable to work but now im getting not target for LLPluginTest errors druing the configure
[2015/03/02 07:05]  Wolfpup (wolfpup.lowenhar): and the built viewer im currently running dose not have QuickTime due to a def conflict between fp.h and math.h
[2015/03/02 07:06]  Oz Linden: I’m afraid I can’t be of much help with that
[2015/03/02 07:07]  Oz Linden: The least-effort alternative is to ignore quicktime for now. We’re revamping how all that is done, so any effort spent on it now will have a very short lifetime anyway
[2015/03/02 07:07]  Oz Linden: is there something you really care about having quicktime for?  (just curious)
[2015/03/02 07:08]  Wolfpup (wolfpup.lowenhar): the thing is if i buld the viewer useing the VS2010 tool chain i get QuickTime to build just fine
[2015/03/02 07:09]  Oz Linden: a lot changed
[2015/03/02 07:09]  Wolfpup (wolfpup.lowenhar): and there are some places i use to go that have media that is .mov
[2015/03/02 07:09]  Wolfpup (wolfpup.lowenhar): and that is a QuickTime media format
[2015/03/02 07:10]  Wolfpup (wolfpup.lowenhar): as well as mp4 and m4a
[2015/03/02 07:10]  Wolfpup (wolfpup.lowenhar): /me knows this since he also dose video encodeing
[2015/03/02 07:11]  Oz Linden: we should have a public project pretty soon for our new web plugin stuff
[2015/03/02 07:11]  Yuzuru (yuzuru.jewell): Showing mp4 is very important for me..
[2015/03/02 07:12]  Oz Linden: at least in theory there should be other ways to play mp4
[2015/03/02 07:12]  Yuzuru (yuzuru.jewell): Oz, Will the html buildin viewer support HTML5?
[2015/03/02 07:12]  Nal (nalates.urriah): Is CEF going to be a plugin?
[2015/03/02 07:12]  Oz Linden: the new one will yes
[2015/03/02 07:12]  Wolfpup (wolfpup.lowenhar): i have ~600GB of mp4’s that is on my server that is being shared via torrents right now
[2015/03/02 07:12]  さくら (sakuranoel.fayray): Mac can’t see Flash ;(
[2015/03/02 07:12]  Wolfpup (wolfpup.lowenhar): well there is FFShow decoder that is OS
[2015/03/02 07:13]  Wolfpup (wolfpup.lowenhar): Media Player Home Cinema used that decoder and LAV as well which is also OS
[2015/03/02 07:14]  Yuzuru (yuzuru.jewell): About CEF, https://jira.secondlife.com/browse/OPEN-218
[2015/03/02 07:14]  Wolfpup (wolfpup.lowenhar): and those handel even the newes x265 encodeing
[2015/03/02 07:15]  Wolfpup (wolfpup.lowenhar): ok i just opend that link in the internal browser and it is not working
[2015/03/02 07:15]  Oz Linden: well, in theory the whole point of the current SLPlugin system was that people could create new media plugins and contribute them. As far as I know, that’s never actually happened.
[2015/03/02 07:16]  Martin RJ (martinrj): I had to log in to Jira first, then click the link again
[2015/03/02 07:17]  Nal (nalates.urriah): It seems everyone forgot about being able to add plugins for media.
[2015/03/02 07:17]  Oz Linden: I should get the status of that updated… we’re farther along than it shows now
[2015/03/02 07:17]  Wolfpup (wolfpup.lowenhar): knid of likie what had happened with HACD ?
[2015/03/02 07:18]  Oz Linden: I’m not familiar with that
[2015/03/02 07:19]  Wolfpup (wolfpup.lowenhar): that was during when mesh was being introduced
[2015/03/02 07:19]  Wolfpup (wolfpup.lowenhar): it has been a few years
[2015/03/02 07:19]  Yuzuru (yuzuru.jewell): What is HACD?
[2015/03/02 07:20]  Wolfpup (wolfpup.lowenhar): and OS version of Havok’s Mesh Decomp system
[2015/03/02 07:21]  Yuzuru (yuzuru.jewell): Ah, the function to make convex hull?
[2015/03/02 07:22]  Wolfpup (wolfpup.lowenhar): yep
[2015/03/02 07:22]  Wolfpup (wolfpup.lowenhar): open-105 was the orginal issue for that
[2015/03/02 07:22]  Yuzuru (yuzuru.jewell): https://jira.secondlife.com/browse/OPEN-105
[2015/03/02 07:22]  Nal (nalates.urriah): Wolf, I would suggest you ask a Firestorm Dev about HACD. Those supporting opensim would have the most motivation to use it. – Oz, will we get any info on the development road map you adopted? Some general idea?
[2015/03/02 07:23]  Oz Linden: nope
[2015/03/02 07:23]  Oz Linden: 🙂
[2015/03/02 07:23]  Wolfpup (wolfpup.lowenhar): i knoe FS dose use it as i build that viewer more regularly
[2015/03/02 07:23]  Nal (nalates.urriah): Oooh NOoooo. We’ll have to hire spies.
[2015/03/02 07:23]  Oz Linden: We
[2015/03/02 07:24]  Wolfpup (wolfpup.lowenhar): right now im only working on the LL viewer because of the new build tool chain
[2015/03/02 07:24]  Oz Linden: We’ll talk about things as we get close enough to having them ready that it matters.
[2015/03/02 07:25]  Wolfpup (wolfpup.lowenhar): Oz the only reasin that im able to be here to day is that im on Vacation from my job that pays the bills
[2015/03/02 07:25]  Oz Linden: Vacations are good
[2015/03/02 07:25]  Nal (nalates.urriah): I understand… but, its no fun that way. 🙂
[2015/03/02 07:26]  Nal (nalates.urriah): Did we ever get any stats on how many people have ALM enabled?
[2015/03/02 07:27]  Oz Linden: No… it’s not one of the things we include in the stats data
[2015/03/02 07:28]  Oz Linden: we can approximate it by looking at settings in crash reports, but that’s a poor sample since people with underpowered systems crash much more often than those with powerful systems
[2015/03/02 07:29]  Oz Linden: so we haven’t even done that
[2015/03/02 07:29]  Wolfpup (wolfpup.lowenhar): ALM ?
[2015/03/02 07:29]  Oz Linden: I got a new Mac over the weekend… way way better frame rate now 🙂
[2015/03/02 07:29]  Nal (nalates.urriah): That makes sense. Its also one of those things we don’t seem to be able to get a handle on from general conversation for SL users. – Congrats on the new Mac
[2015/03/02 07:29]  さくら (sakuranoel.fayray): oh
[2015/03/02 07:30]  Martin RJ (martinrj): congrats
[2015/03/02 07:31]  Nal (nalates.urriah): What kind of FPS are you getting?
[2015/03/02 07:31]  Wolfpup (wolfpup.lowenhar): Oz i also have a updated system since the beginning of the year thx to fans of a fan sub group i work with
[2015/03/02 07:31]  Martin RJ (martinrj): I wish Apple would use AMD graphics chips again in their PCs (as they did until 2010), so that LL would focus more on amd-specific bugs
[2015/03/02 07:31]  Martin RJ (martinrj): 🙂
[2015/03/02 07:31]  Oz Linden: varys a lot, but it’s more than double what I was getting
[2015/03/02 07:32]  Oz Linden: my old system had an amd card, this one is an NVIDIA 750
[2015/03/02 07:32]  Nal (nalates.urriah): Do you see FPS drop by huge percentages in crowds of 20+ avatars?
[2015/03/02 07:33]  Wolfpup (wolfpup.lowenhar): Nvidia is more OS frindly than AMD
[2015/03/02 07:33]  Yuzuru (yuzuru.jewell): New iMac have NVIDIA 750M.
[2015/03/02 07:33]  Oz Linden: well, I’m going to tell IT to give my AMD system to QA
[2015/03/02 07:33]  Oz Linden: I haven’t experimented much yet, Nal
[2015/03/02 07:33]  Martin RJ (martinrj): my laptop also has a NVIDIA gpu
[2015/03/02 07:33]  Oz Linden: but I’m using the new settings for limiting avatar impact, so I don’t expect it will be too bad
[2015/03/02 07:34]  Martin RJ (martinrj): I can’t stand those generalizations about gpus hehe
[2015/03/02 07:35]  Wolfpup (wolfpup.lowenhar): at least with this new system i can build the LL stock viewer in less than an hour where as before it would take a few hours
[2015/03/02 07:36]  Martin RJ (martinrj): do you have any framerate drops when the content of  a region is still loading, Oz?
[2015/03/02 07:36]  Nal (nalates.urriah): I saw someone asking about Lab generated GPU performance tables… Is the Lab going to publish one? I think GPU alone would be misleading.
[2015/03/02 07:36]  Oz Linden: I don’t keep the stats floater up routinely, so I don’t notice Martin
[2015/03/02 07:36]  Martin RJ (martinrj): I notice that on my laptop every time I log in to a region with lots of textures
[2015/03/02 07:36]  Martin RJ (martinrj): e.g. a forest
[2015/03/02 07:37]  Oz Linden: that would make sense – there’s a lot of texture decoding to do
[2015/03/02 07:37]  Wolfpup (wolfpup.lowenhar): i see high data traffic but no real FPs drop on my new system
[2015/03/02 07:37]  Nal (nalates.urriah): When textures and mesh are loading I lose FPS. GTX560
[2015/03/02 07:38]  Nal (nalates.urriah): What is your new system Wolf?
[2015/03/02 07:38]  Oz Linden: not too surprising, Nal… the viewer is usually cpu bound, so if it’s doing one thing it’s not doing another
[2015/03/02 07:38]  Wolfpup (wolfpup.lowenhar): with where i log in at since there is alot of sculpties
[2015/03/02 07:39]  Wolfpup (wolfpup.lowenhar): CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (3400.07 MHz)
Memory: 8074 MB
OS Version: Microsoft Windows 7 64-bit Service Pack 1 (Build 7601)
Graphics Card Vendor: NVIDIA Corporation
Graphics Card: GeForce 9500 GT/PCIe/SSE2
[2015/03/02 07:39]  Wolfpup (wolfpup.lowenhar): and that is from the SL about floater
[2015/03/02 07:39]  Nal (nalates.urriah): How many cores, Wolf?
[2015/03/02 07:40]  Wolfpup (wolfpup.lowenhar): quad with speed steping and hyper threading
[2015/03/02 07:41]  Nal (nalates.urriah): That’s almost an 8 core. Is the 9500GT an old card?
[2015/03/02 07:41]  Wolfpup (wolfpup.lowenhar): yes it is
[2015/03/02 07:41]  Wolfpup (wolfpup.lowenhar): the vid card was from my old system
[2015/03/02 07:41]  Nal (nalates.urriah): Wow. What range of FPS do you get?
[2015/03/02 07:42]  Wolfpup (wolfpup.lowenhar): infact i still have those parts laying around here some where
[2015/03/02 07:42]  Wolfpup (wolfpup.lowenhar): well right now im getting 16FPS but i have been upto ~50FPS
[2015/03/02 07:43]  Wolfpup (wolfpup.lowenhar): but i do have mutiple browsers open and other things going on as ell
[2015/03/02 07:43]  Nal (nalates.urriah): All the textures have loaded and I’m getting 29 w/GTX560
[2015/03/02 07:43]  Wolfpup (wolfpup.lowenhar): and SL is full screen right now
[2015/03/02 07:44]  Nal (nalates.urriah): Multiple browsers will slow things down. Do you have any more occurrences of texture thrashing with multiple browsers open?
[2015/03/02 07:45]  Wolfpup (wolfpup.lowenhar): im talaking external browsres
[2015/03/02 07:45]  Nal (nalates.urriah): Duh.. I was thinking viewers and saying browsers… sorry
[2015/03/02 07:47]  Wolfpup (wolfpup.lowenhar): I have Chrome open with 8 tabs and FF open with 4 tabs plus 2 differnt irc clients Cwgyn64 notepad++ with multiple docs open
[2015/03/02 07:47]  Nal (nalates.urriah): Oz how are the stats on CDN and CDN in genreal?
[2015/03/02 07:47]  Oz Linden: The CDN is doing an excellent job
[2015/03/02 07:48]  Yuzuru (yuzuru.jewell): Hello, Mona.
[2015/03/02 07:48]  Nal (nalates.urriah): Mona poofed….
[2015/03/02 07:48]  Oz Linden: we’re continuing to experiment with different configurations, but the performance results we’re seeing are great and the load reductions on the sim hosts are very significant
[2015/03/02 07:49]  Nal (nalates.urriah): Are you experimenting with different CDN hosts? Do you get stats from the CDN people?
[2015/03/02 07:50]  Nal (nalates.urriah): people=companies
[2015/03/02 07:51]  Oz Linden: We have experimented with more than one provider, and we do get stats from each, though mostly we rely on our own measurements
[2015/03/02 07:52]  Oz Linden: I need to wrap up a few minutes early today – any last minute issues?
[2015/03/02 07:52]  Nal (nalates.urriah): Can you tell how long the CDN caches live? I seem to hit a lot of regions and get what I think is a cold CDN cache load.
[2015/03/02 07:53]  Oz Linden: yes, some of them age out more quickly than we’d like
[2015/03/02 07:53]  Martin RJ (martinrj): do you have news on the recent reports of failing group chats (particularly after the last LL changes)?
[2015/03/02 07:53]  Oz Linden: of course, if you just log in to SL constantly, you’d help us to keep the caches warm 🙂
[2015/03/02 07:53]  Martin RJ (martinrj): many Firestorm-users reported that the Firestorm-Support group chat fails to load
[2015/03/02 07:54]  Nal (nalates.urriah): 🙂
[2015/03/02 07:54]  Oz Linden: I saw some reports, Martin, but we have not had a chance to do a post-mortem on them yet
[2015/03/02 07:54]  Oz Linden: it’s still early in California :-_)
[2015/03/02 07:55]  Oz Linden: time for me to go
[2015/03/02 07:55]  Nal (nalates.urriah): Are you going to be doing any work on the viewer caching system?
[2015/03/02 07:55]  Oz Linden: thanks for coming all
[2015/03/02 07:55]  Martin RJ (martinrj): I always suspect it’s a Firestorm-specific thing : )
[2015/03/02 07:55]  Nal (nalates.urriah): OK, thanks Oz
[2015/03/02 07:55]  Martin RJ (martinrj): goodbye Oz!
[2015/03/02 07:55]  Yuzuru (yuzuru.jewell): Thank you, Oz.
[2015/03/02 07:55]  さくら (sakuranoel.fayray): Thank you Oz.
[2015/03/02 07:56]  Wolfpup (wolfpup.lowenhar): nal whein i un maximized the viewer my FPS doubled
[2015/03/02 07:57]  Nal (nalates.urriah): I get some improvement when I go from Full Screen to about 1/3 screen. But, not double.
[2015/03/02 07:58]  Nal (nalates.urriah): About 1/3 better
[2015/03/02 07:59]  Nal (nalates.urriah): As people leave my FPS goes up
[2015/03/02 08:00]  さくら (sakuranoel.fayray): bye bye
[2015/03/02 08:00]  Nal (nalates.urriah): Thanks for the info on your computer Wolf. I”m starting to buy parts for a new computer.
[2015/03/02 08:00]  Nal (nalates.urriah): Bye all
[2015/03/02 08:00]  Yuzuru (yuzuru.jewell): See you!
[2015/03/02 08:00]  Nal (nalates.urriah): 🙂
