(09:01:31 PM) BryanWB: dan_p: welcome (09:02:24 PM) martin_xsa: anyone else? (09:02:41 PM) mvn071: http://martenvijn.nl ... (09:03:01 PM) arjs [i=Anks@221.134.239.1] entered the room. (09:03:09 PM) martin_xsa: http://wiki.laptop.org/go/XS_Roadmap (09:05:15 PM) cafl: me http://msbit.com/cafl.html -- static version of school website: http://msbit.com/robin/html/ (09:09:51 PM) olpc_wad: cafl: Any relationship with the NYC schools ? Or are they working solo ? (09:10:09 PM) BryanWB: cafl: working w/ Teaching Matters? (09:10:40 PM) cafl: I am freelancing...my daughter teaches at that school...teach for america. It is a charter (09:12:15 PM) olpc_wad: Cool. Martin and I are talking to the NYC schools tmw. as well. When does Icahn Charter School plan to deploy ? (09:12:57 PM) cafl: I am travelling there Thursday. Will be there through the next week. (09:13:38 PM) cafl: I am putting this in one class...4/20th laptop per child (09:15:22 PM) cafl: I hope success will interest the icahn foundation (09:16:47 PM) TTown: Sound is dropping out for short times (from any participant). Anybody else experience this? (09:16:57 PM) crosvera: yeah (09:18:07 PM) martin_xsa: we all like hardware ;-) (09:20:55 PM) mvn071: floss accespoint => wrap/alix/soekris performs well (09:21:15 PM) crosvera: floss? (09:21:20 PM) BryanWB: mvn: needs to be easy to set up accesspoint, i have no experience w/ this (09:21:22 PM) mvn071: opensources (09:21:29 PM) crosvera: yeah (09:21:30 PM) mvn071: linux / bsd (09:22:07 PM) mvn071: just make brigdes, or ssh configs form XS (09:22:13 PM) mvn071: from (09:23:02 PM) olpc_wad: We have noticed that OpenWRT turns cheap access points into good access points, but it adds to the installation overhead. (09:23:23 PM) TTown: Large school scenario: I hear with traditional access points 1 one server for 250 clients is normal. Using no high end servers, will server clusters be considered (--> red hat cluster management suite) (09:23:49 PM) crosvera: damn it i don't have more money (09:23:55 PM) mvn071: ack, and not very scalable hardware (redoing) (09:24:16 PM) olpc_wad: We are trying to avoid clusters if possible... (09:25:41 PM) crosvera: I am out of the conference (09:27:57 PM) BryanWB: sorry crosvera (09:28:08 PM) crosvera: np (09:28:33 PM) crosvera: then you talk me about the conference :D (09:28:41 PM) BryanWB: sure :) (09:28:59 PM) cafl: talking about taxonomy now, crosvera (09:29:09 PM) crosvera: ;) (09:29:17 PM) cafl: on wiki (09:29:24 PM) huslage: olpc_wad: the OpenWRT idea is good, but I found when doing Katrina relief that it was more of a hindrance than useful after a fashion (09:31:15 PM) olpc_wad: I agree, in terms of having to install it on the AP. Did you run into technical problems as well ? (09:31:42 PM) huslage: yeah, mostly in administration issues. (09:31:48 PM) mvn071: linksys had bad capcitors, better take smc (09:32:01 PM) huslage: olpc_wad: has the 50x15 been considered as a school server platform? (09:32:03 PM) BryanWB: huslage: I am wary of learning curve w/ OPenWRT, when we already have a lot of new tech to work w/ (09:32:13 PM) crosvera: cafl, what about backup XO's information? (09:32:18 PM) huslage: exactly BryanWB (09:32:34 PM) huslage: http://50x15.com/en-us/ (09:33:56 PM) martin_xsa: thanks for the yum comment, I'll see if I can make it more reliable (09:35:01 PM) martin_xsa: our plan is to have the same mechanism that can be deployed via USB key or internet (09:35:20 PM) martin_xsa: or mixed delivery (09:35:28 PM) mvn071: bootable usb-stick..? (09:35:36 PM) cafl: great ... easy to be blinded by being used to reliability (09:35:54 PM) martin_xsa: mvn071, the usb key just has a signed script (09:36:18 PM) martin_xsa: cafl, I'm familiar with _very_ bad connectivity areas: Pacific islands (09:36:54 PM) olpc_wad: 50x15 is not environmentally sealed, and has no WAN connection. (09:37:13 PM) huslage: what about customizations? (09:37:21 PM) cafl: I'm not...this last 3 months has been a revelation (09:37:32 PM) olpc_wad: I looked at it, but it is underpowered and doesn't get us much. AMD is suggesting a miniITX IPC if you are going to use AMD chips. (09:38:35 PM) huslage: yrsh (09:38:37 PM) huslage: yeah (09:38:47 PM) huslage: we looked at it a while back at Inveneo (09:38:49 PM) huslage: it sucked (09:38:56 PM) huslage: i didn't know if it had gotten better (09:46:20 PM) sulocha1 [n=root@124.41.199.252] entered the room. (09:47:37 PM) TTown: Birmingham scenario: 20+% of student population changed schools within the last 12 months (09:47:59 PM) mvn071: crypted backup's with user key (09:48:03 PM) mvn071: ? (09:49:04 PM) BryanWB: Yo sulo (09:49:17 PM) sulocha1: hey bryan (09:49:18 PM) sulocha1: hey guys (09:49:51 PM) mvn071: edubuntu ? (09:49:58 PM) crosvera: what are you talking about right now? (09:50:22 PM) cafl: martin_xsa: why debian instead of ubuntu which is a secondary distro in the xo context? (09:50:36 PM) BryanWB: cafl: debian more stable (09:50:45 PM) dan_p: debian longer-term? (09:51:39 PM) crosvera: yeah, Debian has several rules with the software update (09:51:43 PM) mvn071: oke (09:52:58 PM) dan_p: kernel? (09:53:10 PM) crosvera: dan_p, ah? (09:53:49 PM) dan_p: whacky hardware which might not be supported on stock debian kernels (09:54:32 PM) huslage: yes dan_p (09:55:26 PM) crosvera: but, it could be possible configure the kernel package (09:56:01 PM) dan_p: yep. Indeed/backports (09:56:26 PM) dan_p: woo for unsexy ;) (09:56:35 PM) sulocha1 left the room. (09:56:37 PM) martin_xsa: Cobol! (09:59:31 PM) cafl: martin_xsa: Consider that schools will be adding/customizing application content (e.g. websites, etc.) (10:01:24 PM) mvn071: http://reductivelabs.com/trac/puppet/wiki/PuppetOnDebian (10:04:05 PM) huslage: puppet is very nice for what martin_xsa is talking about (10:08:21 PM) mvn071: what is K<x>? (10:08:37 PM) olpc_wad: Kindergarden through <x> grade (10:08:38 PM) martin_xsa: http://moodle.org/mod/forum/view.php?f=731 (10:08:51 PM) mvn071: tnks (10:09:32 PM) dan_p: (I am a developer) and we host over 100 K6 moodles (10:09:56 PM) dan_p: But I am not clear on the pedology used in these schools (10:10:28 PM) martin_xsa: carol - thanks for waiting a sec (10:11:09 PM) mvn071: sorry_ have to show up @ dinner => bye => tnhks (10:11:11 PM) martin_xsa: carol, go ahead (10:11:14 PM) martin_xsa: please :-) (10:11:21 PM) dan_p: http://cleo.net.uk/getfile.php?src=778/CLEO_PrimaryThemesFlyer.pdf (10:12:47 PM) bemasc left the room (quit: "Quit"). (10:14:32 PM) cafl: static version of school website: http://msbit.com/robin/html/ (10:17:24 PM) BryanWB: I would like to see Moodle as the primary CMS. Has the critical mass in education. (10:20:47 PM) BryanWB: dan_p: what's your e-mail address? want to talk w/ you about moodle for k-6 kids. (10:21:01 PM) dan_p: talktodan@gmail.com (10:21:07 PM) huslage: nice (10:21:52 PM) BryanWB: dan_p: do you have examples we can look at from the regular Internet? We need a very, very simple UI for our Moodle install in Nepal. More for teachers than the kids. (10:22:43 PM) dan_p: I am not sure there are any which you'd be able to get anywhere with (they are closed environments for thes chools) (10:23:19 PM) BryanWB: dan_p: Argh. We want to use Moodle as 1) layout lesson plans for teachers so they don't feel at a loss what do to w/ the XO 2) forums for kids 3) blogging (10:23:45 PM) BryanWB: let's use Sakai! :) joking (10:27:55 PM) martin_xsa: cafl, I have to confess that you are quite an outstanding Drupal user (10:35:53 PM) martin_xsa: open questions? (10:37:03 PM) cafl: martin_xsa: getting special hardware at deployments like mine ... antenna chargers eg (10:38:30 PM) olpc_wad: cafl: antenna chargers ? (10:38:53 PM) olpc_wad: Active antennas and chargers ? Power supplies for standalone repeaters ? (10:38:58 PM) cafl: live antennas, new gang chargers (10:39:17 PM) cafl: typing one-handed (10:39:20 PM) crosvera: martin_xsa, what about XS admin interface? (10:40:07 PM) cafl: active antennas, new gang chargers (10:40:07 PM) martin_xsa: todo: moodle+Pootle (10:40:13 PM) olpc_wad: cafl: For that installation, we have to recommend conventional APs, not active antennas. (10:40:20 PM) huslage: that hurts my brain (10:40:31 PM) olpc_wad: Are you in touch with Richard Smith about gang chargers ? (10:40:55 PM) TTown: Question: Scalability for large schools - if clusters are unwanted and fairly low cost of the shelf hardware the main server resource. At what student number do we expect to hit the ceiling? (10:41:15 PM) martin_xsa: x11vnc (10:41:17 PM) martin_xsa: ? (10:41:34 PM) huslage: TTown: that depends on the hardware really (10:41:44 PM) martin_xsa: export gdm - ? (10:41:53 PM) crosvera: x11vnc?? (10:41:56 PM) cafl: olpc_wad: I am using a wap, but would be interested in the chargers. just thought it is something that should be documented (10:42:04 PM) huslage: they are talking about sharing screens, crosvera (10:42:13 PM) crosvera: aaaaa (10:42:15 PM) huslage: it is not a server activity really (10:42:24 PM) martin_xsa: crosvera, we'll talk admin UI later :-) (10:42:34 PM) crosvera: with vinagre (10:42:35 PM) BryanWB: huslage: not really a server activity but great for teacher training (10:42:40 PM) huslage: yes (10:42:43 PM) crosvera: with vinagre yo can share screens (10:42:57 PM) crosvera: *you (10:42:58 PM) huslage: i don't disagree, just telling him what we're talking about (10:43:32 PM) olpc_wad: We are working to bring up early prototypes, but need people interested in buying them to go further. You can send mail to rsmith@laptop.org to let him know you are interested. (10:43:56 PM) cafl: tx (10:46:06 PM) crosvera: another tool to share screens http://italc.sourceforge.net/ (10:46:41 PM) olpc_wad: http://wiki.laptop.org/go/Remote_display (10:46:53 PM) olpc_wad: For sharing a display between laptops (10:48:04 PM) martin_xsa: thanks all!
