Transcript of Andrew Linden's office hours:

[17:04] Arawn Spitteler: Hi, Simon. I was just bemoaning, that things are textured, rather than using stained plywood.
[17:05] Sindy Tsure: heya andrew
[17:05] Arawn Spitteler still sees an awful lot of Grey.
[17:05] CloudMan Ying: yo andrew
[17:05] Patnad Babii: hello Andrew :)
[17:05] Andrew Linden: Hi everyone
[17:05] Sindy Tsure: oh! sidewinder got evicted??
[17:06] Sindy Tsure sees somebody else has moved in across the water
[17:06] Arawn Spitteler: Is his parcel missing?
[17:06] Simon Linden: He's not working at LL now
[17:06] Arawn Spitteler: He might have gotten his own sim
[17:06] Arawn Spitteler: Evicted, hten.
[17:06] Arawn Spitteler: I hope that mean he has a new job
[17:06] Sindy Tsure had not heard that
[17:07] Sindy Tsure: not like i get updates from philip & m, though..
[17:07] Simon Linden: He called me the other day, it's also on http://foo.secondlifeherald.com/slh/2008/12/sidewinder-lind.html
[17:08] Adz Childs: heh. confirmed.
[17:08] Andrew Linden: Alright... announcements.
[17:08] Sindy Tsure: "Espresso Saarinen recalled Sidewinder as an effective grown-up who delivered a much more stable sim platform and was known for working with inmate^h^h^h^h^h^hresidents... he will be sorely missed"
[17:08] Sindy Tsure: lol
[17:08] Sindy Tsure hopes he's off doing something he enjoys..
[17:08] Sindy Tsure shuts up and lets andrew talk
[17:08] Andrew Linden: I think 1.25 is on hold, unfortunately.
[17:08] Andrew Linden: Don't know when it will get out, but not by Christmas.
[17:09] Andrew Linden: There is no santa.
[17:09] CloudMan Ying: :O
[17:09] Patnad Babii: new leak were found?!
[17:09] Andrew Linden: Not new problems, but the existing problems were not satisfactorily tracked down.
[17:10] Andrew Linden: The holiday shedule makes it harder too
[17:10] Andrew Linden: so I think the #deploy team is just not going to try until Jan
[17:10] Sindy Tsure: is there some new plan of attack for 1.25 or is this just a straight delay?
[17:10] Sindy Tsure: ack!
[17:10] Sindy Tsure: hi xl
[17:10] Patnad Babii: i wanted to ask something, is it true that mesh will be added within a 6 month delay ?
[17:11] XLR8RRICK Hudson: Hello everyone
[17:11] CloudMan Ying: hi
[17:11] Simon Linden: The holidays are getting in the way ... basically if it didn't get out this week, we were going to push it to next month
[17:11] Patnad Babii: howdy
[17:11] Simon Linden: Hi
[17:11] Andrew Linden: That said, there is some chunk of code that *must* get deployed because of some deadline about a solution/fix to the openspace changes
[17:12] Andrew Linden: This was all news to me, but there was some announced deadline about early Jan something would be done
[17:12] XLR8RRICK Hudson: 1.25 is sleved till Jan
[17:12] Sindy Tsure: prospero mentioned that.. somethings about new code to let it know about more sim types
[17:12] XLR8RRICK Hudson: but 1.24 .10 is coming
[17:12] Andrew Linden: so they are trying to get that part isolated, tested, and deployed by the first week in Jan. Right
[17:12] Andrew Linden: so in the meantime we'll be working on 1.25
[17:13] Andrew Linden: and it will go out sometime afte 1.25.10
[17:13] XLR8RRICK Hudson: 1.24.10
[17:13] Andrew Linden: er... right thanks
[17:13] Andrew Linden: 1.24.10
[17:13] Andrew Linden: It won't have any bug fixes in it.
[17:13] Sindy Tsure: http://forums.secondlife.com/showpost.php?p=2258248
[17:13] Andrew Linden: all the bug fixes are tied up in 1.25
[17:13] Sindy Tsure: not to mention 64-bit sims
[17:14] Andrew Linden: yeah, we're working on installing a 64bit operating system on our simulator hosts
[17:14] Sindy Tsure: i thought they were already 64-bit debian? no?
[17:14] Andrew Linden: I saw an email go by yesterday saying something to the effect of:
[17:15] Andrew Linden: "server-1.26 will depend on etch (64bit debian) being deployed to all simulator hosts. No pressure."
[17:15] Sindy Tsure: lol
[17:15] Andrew Linden: that email went out to the group working on getting etch onto the hosts
[17:16] Arawn Spitteler: Could wwe have a sketch of Etch?
[17:16] Sindy Tsure: ha
[17:16] Andrew Linden: we have 64bit hardware across the board, however most of it is currently running 32bit
[17:16] Andrew Linden: 32bit operating system
[17:16] Sindy Tsure: when's the goal date for server-1.26? february or so?
[17:17] Simon Linden: Roughly ... we're gradually learning to stop thinking of dates and in versions only :)
[17:17] Sindy Tsure: :)
[17:18] Andrew Linden: I think the hopeful deploy month of 1.26 would be February
[17:18] XLR8RRICK Hudson: will it be dependant on 1.25 running stable
[17:18] Patnad Babii: i heard cg talking about 512x512 sims, is it by v1.26 its going to kick in ?
[17:18] Andrew Linden: soon after 1.25 ships we'll be branching 1.26 and testing will begin
[17:19] Patnad Babii: and are the 64bit machine going to be rebranded Class 6 ?
[17:19] XLR8RRICK Hudson: Beta Grid test ?
[17:19] Simon Linden: Big regions are still just an idea now ... not coming soon
[17:19] Andrew Linden: No, class-6 will be truly new hardware
[17:19] Andrew Linden: all of our hardware (class-3 and higher) is 64bit capable
[17:19] Patnad Babii: so class-5 will become superior then ?
[17:19] Sindy Tsure: any details you can leak on class 6 hardware?
[17:20] Andrew Linden: no rebranding of the hardware
[17:20] Andrew Linden: If I knew details about class-6 i would happily leak them.
[17:20] Sindy Tsure: we won't tell.. honest!
[17:20] Patnad Babii: or maybe you will just plug more sim into the same machine
[17:20] Sindy Tsure: ah well.. :)
[17:20] XLR8RRICK Hudson: has all the Memory upgrades been done now ?
[17:20] Simon Linden: Speaking of hardware, someone was asking me about some tests because they wanted to try running one of our hosts with a solid-state disk drive
[17:21] Andrew Linden: I haven't heard about any memory upgrades
[17:21] Simon Linden: I haven't heard the results, however
[17:21] Sindy Tsure: ooo.. SSD!
[17:21] Andrew Linden: which doesn't mean they aren't happening.
[17:21] XLR8RRICK Hudson: so it looks to me like Hardware is easy
[17:21] Sindy Tsure: there were some racks of new machines in phoenix that all had 1/2 the memory they were supposed to have.. last month i think.. took a few rounds to get them updated
[17:21] XLR8RRICK Hudson: Software is hard
[17:21] Simon Linden: I'm really curious how that would affect things ... we're a long way from updating the full grid, but it would be cool if they speed things up
[17:22] Sindy Tsure: how much disk does a sim host have now?
[17:22] Andrew Linden: yeah I think I heard that we have an SSD demo machine we were going to test out
[17:22] Patnad Babii: do you guys know anything about meshed object coming up soon?
[17:22] Andrew Linden: Sim hosts have far more HD space than they need
[17:22] Sindy Tsure: object or avatars?
[17:23] Andrew Linden: but faster IO rates would help us
[17:23] Sindy Tsure nods
[17:23] Sindy Tsure: think i read that the early ssd drives were actually slower than sata-ii.. i'm sure that's been long fixed, tho
[17:23] Simon Linden: No, I don't know about the mesh work other than casual feature discussions
[17:24] Andrew Linden: No Patnad, the meshed object project is driven primarily from the viewer side of things. Best to ask someone like Steve, Qarl, or Runitai Linden about it.
[17:24] Simon Linden: yeah, this was some test unit from Intel, so it should be fast
[17:24] Arawn Spitteler: Disk Space is as cheap as the Desert Sands, and, how wealthy are they, who can cross the sands cheaply.
[17:24] Patnad Babii: ok well ive been asked it should be deployed within 6 months
[17:24] Patnad Babii: oops
[17:24] Patnad Babii: i mean i've heard
[17:24] Andrew Linden: another announcement before I forget: I won't be able to attend office hours next week
[17:24] Andrew Linden: neither Tues or Thurs
[17:25] Andrew Linden: Simon, are you going to be in on Tues?
[17:25] Simon Linden: I can be around on Tuesday
[17:25] Sindy Tsure: what! you're not working xmas?!?!
[17:25] Sindy Tsure: :)
[17:25] Simon Linden: They're letting me out for a furlough...
[17:25] XLR8RRICK Hudson: Happy Holidays !
[17:25] Sindy Tsure: sorry.. today was my last day of work until next year.. a bit giddy..
[17:25] Andrew Linden: Ok so sounds like Simon will attend on Tues. But no office hours on Thursday.
[17:26] Andrew Linden: That is, Thursday Dec 25th
[17:26] Simon Linden: The following week will be the same - I can cover Tuesday but we should cancel Thursday
[17:26] Sindy Tsure: national hangover day
[17:26] Andrew Linden: I should be able to attend Tuesday the 30th too.
[17:27] Arawn Spitteler has a horrble vision, of all those Christmas Computers, convincing the developers that all clients can access with Graphics Cards.
[17:27] Andrew Linden: I think last year I was going to attend office hours on the 1st, but forgot.
[17:27] Arawn Spitteler: I recall it was a tad sparse, at one point.
[17:28] Andrew Linden: Or maybe it was new years eve. In any case, I don't think I'll be able to attend office hours on Jan 1st 2009
[17:28] XLR8RRICK Hudson: to be expected
[17:28] Sindy Tsure nods
[17:28] Andrew Linden: I think we were talking about class-6 hardware and SSD drives
[17:29] XLR8RRICK Hudson: SSD
[17:29] Andrew Linden: I'll try to ask our operations team to see if they have any info on class-6
[17:29] Andrew Linden: I'm curious myself.
[17:29] Andrew Linden: er right... just SSD
[17:29] Arawn Spitteler: I wouldn't know 4 from 5
[17:29] Patnad Babii: oh and is it by 1.26 that there will be 512x512 sims ?
[17:29] XLR8RRICK Hudson: Performance
[17:30] Andrew Linden: no Patnad, the 512x512 project is vapor, blue-sky
[17:30] Patnad Babii: well Cg seemed convinced it was going to happen soon
[17:30] Andrew Linden: we've talked about it, how it might be done, but have not started, and it isn't in the schedule
[17:30] Arawn Spitteler: It might be nice, if a sim could shrink people. I recall a race track, where the drivers are almost Tiny
[17:30] Simon Linden: It's a pretty tough change, as our whole system is based on 256x256 ... just look at the map tiles, for example
[17:30] Sindy Tsure: greenies, arawn
[17:31] Andrew Linden: hrm... well maybe Cg is privy to some info that I haven't heard about.
[17:31] Sindy Tsure: there was talk of that last week, patnad.. of some of the challanges LL would have in doing it.. transcripts are usually on the wiki
[17:32] Andrew Linden: The only way I can think of doing it would be to have a simulator process that hides the fact that it is 512x512 (or some other non-legacy size)
[17:32] Andrew Linden: that is, it would communicate to the viewer and other regions as if it were several sims, but would have one big physics engine and script engine
[17:33] XLR8RRICK Hudson: oh no another Sim
[17:33] Sindy Tsure: one sim process?
[17:33] XLR8RRICK Hudson: Huge Sim
[17:33] Patnad Babii: yeh that kind of sim that can hold 400 av :)
[17:33] Andrew Linden: Yeah, one sim process but with a bigger footprint
[17:33] XLR8RRICK Hudson: Mega Sim
[17:33] Simon Linden: BAR project - Big Ass Regions :)
[17:33] XLR8RRICK Hudson: Jack will love it
[17:33] Andrew Linden: uh... it wouldn't handle any more avatars
[17:34] Sindy Tsure: could be a big win with them all sharing caches and stuff, if everything else scaled to being able to deal with 400 avatars..
[17:34] Andrew Linden: not until we overhaul a bunch of other code
[17:34] Arawn Spitteler: Sim Crosing would have to be suppressed, is the best I can imagine.
[17:34] Sindy Tsure: noo... sim crossings would rock! :)
[17:34] Patnad Babii: you know with opensim its something that is possible now to define any size of sim
[17:34] Andrew Linden: sim crossign would not happen when walking within the big region, so that problem might be reduced in some cases
[17:35] Andrew Linden: yes, opensim should be able to define any size. That is the right way to do it.
[17:35] Simon Linden: Well, we'd probably first make them isolated, like big islands so there are no neighbors (and crossings)
[17:35] Andrew Linden: Actually... if we had to overhaul the viewer so that it did not assume 256x256... so it could connect to arbitrarily sized opensim regions...
[17:36] Andrew Linden: then our problem would be half solved.
[17:36] Andrew Linden: perhaps opensim will provide the impetus we need to actually get it done
[17:36] Sindy Tsure: is there really that much code that assumes 256x256 in the viewer?
[17:36] Andrew Linden crosses his fingers that it is so simple
[17:36] XLR8RRICK Hudson: cool
[17:36] Patnad Babii: hopefully :)
[17:36] Simon Linden: Tjere
[17:36] Simon Linden: oops...
[17:37] Andrew Linden: I'm not sure how hard it would be to abstract the size of the region in the viewer.
[17:37] Simon Linden: there's going to be a lot of stuff 'around the edge' that will need fixing, like the map tiles I mentioned
[17:37] Simon Linden: We have a system that generates those, and it's built for 256x256 only
[17:38] Patnad Babii: what about the megaprims liberation will it happen any soon ?! :)
[17:38] Sindy Tsure: oh! slurl and the in-world maps finally got updated.. a big TY for whoever did that!
[17:38] Arawn Spitteler imagines 512X512 very small meters.
[17:38] Andrew Linden: Alas no Patnad. I can't speculate on a ETA for that
[17:38] XLR8RRICK Hudson: I like Open Grid and there 100 m Prim size limit
[17:38] Patnad Babii: i saw a chat recording back in 2007 that you had this project going on
[17:38] Andrew Linden: unfortunately the "absoutely necessary work" has been piling up and not getting smaller
[17:38] Andrew Linden: yeah I did
[17:39] Patnad Babii: would be nice
[17:39] Patnad Babii: in opensim its quite handy
[17:39] Andrew Linden: There is some work done that is toward that goal, done by Qarl Linden
[17:39] Sindy Tsure: andrew actually came to the forums on that one!
[17:39] Andrew Linden: it just needs a little help to get through QA and UI design
[17:39] Andrew Linden: and that would be about... 25% toward megaprim liberation
[17:40] Patnad Babii: i dont see why tho you want to make them absolutly not grieffing
[17:40] Andrew Linden: it is impossible to make anything absolutely not griefing
[17:40] Andrew Linden: however, I don't want to exacerbate the greif potentials
[17:40] Arawn Spitteler: Anything grief proofed is a source of Grief
[17:40] Sindy Tsure: "if you make something foolproof, the world will make better fools"
[17:41] XLR8RRICK Hudson: lol
[17:41] Patnad Babii: oki oki, but i mean a prim is a prim, if it have the ability to go up to 256M it doesnt mean all sudenly everyone will do grieffing
[17:42] Patnad Babii: there is a certain number of people who do that.. but they can do it with a mega prim pack they find now.. it shouldnt be different if we allow everyone doing 256x256 prim
[17:42] Arawn Spitteler: People are stupid, and some will choose to manifest this, with Mega Prims. I'd hardly try to remove all potential.
[17:43] Sindy Tsure: but if you drop a prim in the wrong place and walk away, it's more likely to cause problems as the max size goes up
[17:43] Arawn Spitteler: Megaprims are easier to spot.
[17:43] Andrew Linden: I can hope that we can address megaprims in 2009
[17:43] XLR8RRICK Hudson: yes had a 1024 on my sim and 15 others
[17:44] Sindy Tsure: as a mainland dweller, i'm not really excited about big megaprims being available to every newbie..
[17:44] CloudMan Ying: :D
[17:44] Sindy Tsure: up to 40x40 or so is one thing.. sim-sized prims is a different story, imo
[17:44] Arawn Spitteler: 16X32 would fit in any parcel
[17:44] Patnad Babii: well if you dont like prim on your land, don't leave permission to rez to everyone
[17:44] XLR8RRICK Hudson: I think the max size should be 32x32
[17:45] Patnad Babii: and warn your neighbour about it too
[17:45] XLR8RRICK Hudson: 16x32 is good too
[17:45] Sindy Tsure: those permissions go by the center of the prim
[17:45] Arawn Spitteler: I'd leav3e it to th4e sim owner.
[17:45] Patnad Babii: no i think 256x256 is very right
[17:45] Sindy Tsure: or center of the root prim if it's a multi-prim object
[17:45] Andrew Linden: What I'd like to do is get to a point where we can start increasing the max size of prims over a few weeks or months
[17:45] Patnad Babii: opensim use it and if you want to cover your full sim you can
[17:45] Andrew Linden: so we can get a better idea of what the real limits should be
[17:45] XLR8RRICK Hudson: true
[17:45] Sindy Tsure: great.. have fun in opensim
[17:46] Andrew Linden: however... we wouldn't be able to clamp down on the really big ones until we provide some sort of "distant horizon" feature
[17:46] Andrew Linden: where region owners could specify a "sky box" for the horizon
[17:46] XLR8RRICK Hudson: I use a 50m Dome
[17:46] XLR8RRICK Hudson: 3D Video Shows
[17:46] Sindy Tsure: oh.. i like that idea, andrew
[17:46] Andrew Linden: which is one of the "features" very large megaprims are used for
[17:47] Sindy Tsure: i've seen that.. it's a very cool effect
[17:47] Sindy Tsure: mountains off in the distant void
[17:47] Andrew Linden: I don't see why the distant horizon, or the color of the void beyond the edge of the region shouldn't be configurable by the region owner.
[17:47] Patnad Babii: there is megaprim in circulation so why not let any body create them theirself
[17:48] Sindy Tsure: you'd make a lot of people happy with that feature
[17:48] Andrew Linden: that is, no policy reason why. It's just a project that will have to get done along with all the others.
[17:48] XLR8RRICK Hudson: I display Video on the Inside of mine
[17:48] Patnad Babii: i think it will lead to less missuse of them, the big problem with megaprim is when they overlap they cause collision alot
[17:49] Andrew Linden: yes, that is one of the problems
[17:49] Andrew Linden: parcel overlap is another that is just made worse by megaprims
[17:49] Patnad Babii: so if you can adjust the size... then you will be less needed to overlap those
[17:50] Patnad Babii: well i dont see a difference if a prim overlap a parcel by 5M or by 20m
[17:50] Patnad Babii: it overlap and your inside anothers propriety
[17:50] Sindy Tsure: you will if you do it onto land i'm paying for..
[17:51] Andrew Linden: Sindy is right. Also you will realize the difference if your job is to help SL residents with their problems
[17:51] Andrew Linden: (such as our #support team)
[17:51] Sindy Tsure: i can hear the gteam crying from here..
[17:52] Andrew Linden: Oh yeah, one other thing I wanted to mention. I've got a hard stop at 18:00 -- I have to be somewhere later tonight by 19:00
[17:52] Arawn Spitteler: A cheap way to calculate when overlap happens, would be important, but any overlap is trespass.
[17:52] Sindy Tsure: there was a problem somebody mentioned on the forums..
[17:52] Arawn Spitteler: Overlap might be done by bounding box collisions with other parcels.
[17:52] Sindy Tsure: "I have a scripted object i've been working on a for a while now. Twice now, it's gone "corrupt", in that the prim won't rez anymore anywhere (have even tried wearing it.)... have tried clearing cache, making sure i'm even trying to rez it on the ground (as opposed to on top a mega prim), tried rezzing it in the preview grid, tried passing it to someone else to rez...."
[17:53] Patnad Babii: uhm you should just trust people making it a fair use.. if they abuse then you warn them, if they do it again you ban them
[17:53] Arawn Spitteler: He should get that to andrew.
[17:53] Sindy Tsure: i suggested he JIRA it and include the UUID.. hasn't responded, tho
[17:54] Andrew Linden: Sindy, i don't know what is going on with that "corrupt" scripted object.
[17:54] Andrew Linden: Sounds like content loss
[17:54] Andrew Linden: someone would have to investigate the logs and do some digging
[17:54] Arawn Spitteler: Content Loss, but still listed in Content.
[17:54] Sindy Tsure: if an object gets blacklisted, the sim will yell when you try to rez it, right?
[17:54] Sindy Tsure: ...give you some error message?
[17:55] Andrew Linden: yes, I think so Sindy. It sends an alert about why the rez failed.
[17:55] Sindy Tsure: or gray goo fenced
[17:55] Sindy Tsure: ok..
[17:55] Andrew Linden: the GGF only kicks in when certain rates are exceeded
[17:55] Andrew Linden: and it relaxes when the rates drop back down
[17:55] Sindy Tsure: ok.. so that's probably not it
[17:55] Andrew Linden: it has a short-term-memory
[17:55] Andrew Linden: and it also does some alerting via script errors... when it first happes
[17:56] Andrew Linden: happens
[17:56] Sindy Tsure: what's his best bet? jira? support ticket? start stalking you?
[17:56] Simon Linden: Support ticket FTW!
[17:56] Sindy Tsure: 'no opinion' is an acceptable answer.. :)
[17:56] Sindy Tsure: lol.. ok, simon :)
[17:57] Andrew Linden: Stalking me would not be very fruitful. Even a content loss problem like that would not trump the stuff I'm working on, alas.
[17:57] Sindy Tsure: d'oh
[17:57] Patnad Babii: i think ticket might be your best bet
[17:57] Sindy Tsure: mind if i quote that line in the forums, simon?
[17:58] Simon Linden: No, go ahead ... might get me some hate mail from frustrated people, tho
[17:58] Andrew Linden: A very detailed jira ticket, about some very recent events (not more than 7 days old) along with a prod of some linden who has access and know-how for troubleshooting something like that... that is the best bet.
[17:58] Sindy Tsure eeps
[17:58] Arawn Spitteler: Have we a name for this person?
[17:59] Andrew Linden: If I were in bug-fix mode I would take a swing at it if there were a detailed report
[17:59] Sindy Tsure: ok.. i'll tell him to start stalking you then
[17:59] Andrew Linden: I might be there in jan sometime.
[17:59] Sindy Tsure: http://forums.secondlife.com/showthread.php?p=2258652 , arawn
[17:59] Andrew Linden: I'm going to have to leave very soon.
[18:00] Sindy Tsure: i don't know him.. just something i noticed and thought i'd mention..
[18:00] Sindy Tsure: have awesome holidays, andrew & simon!
[18:00] XLR8RRICK Hudson: thanks for sharing your time with us
[18:00] XLR8RRICK Hudson: Happy Holidays everyone !
[18:00] Sindy Tsure: yep! ty both!
[18:00] Arawn Spitteler: It's pobably something trivial, if he doesn't know the Jira, but it could also be the kid, who noticed hte end of the world.
[18:00] Adz Childs: ;0
[18:00] Patnad Babii: yes have happy holidays everyone
[18:00] CloudMan Ying: yup cya guys
