Re: Devel Digest, Vol 53, Issue 56
HI, I was wondering if there was a way to have a different resolution on the screen of the XO 1.5. I know that due to the DCON chip the res cannot be changed to other value that 1200x900, and have been told about Xephyr ( http://dev.laptop.org/ticket/10210). Does anyone have any thoughts/experiences on this? Thanks. Cheers Franco ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Collection key vs Q2E44 (and Q3A41?)
Martin - We've done some quick testing here in the office. It appears that collection keys on Q3A40, Q3A42, and Q3A46 work, provided the laptop is secure-booting. If your machines are not secured, you need to hold down the x game key while booting. Remember that with prettyboot enabled, an unsecured machine may look like it's secure at boot time. Richard and I just tested a SKU99 XO-1.5 (Q3A40 and Q3A42) and a SKUC2 XO-1.5HS machine (Q3A46), all with security disabled. Nothing happened on a normal boot with the collection key, and all worked (stored data on the collection key) if the x game key was held at powerup. - Ed On Jul 30, 2010, at 2:09 PM, Martin Langhoff wrote: Hi Mitch, wasn't aware you were on vacation.

Re: Collection key vs Q2E44 (and Q3A41?)
Martin - Just another note of advice - I discovered a normal-looking USB key that *wasn't* working had a single FAT partition on it, but it had been erased on a Mac and had a GUID partition table. Reformatting with an MBR fixed it. - Ed On Jul 30, 2010, at 2:09 PM, Martin Langhoff wrote: Hi Mitch, wasn't aware you were on vacation.

Re: [Server-devel] Configuration Management Automation : cfpull
Hi Mike, good to see you are thinking along this lines. How advanced are you down this specific track with cfpull? For XS, several deployments are using Puppet, and after a bit of review, I am extremely happy with Puppet, to the extent that expect that (when time allows) we'll have whatever's needed to make Puppet easy to run for XSs. Puppet comes from the hands of a veteran of many 'automatic configuration' tools (Luke Kaines) who's hacked plenty on ISConf (my favourite) and cfengine (my not-favourite ;-) ). He soaked the good and the bad of both, and wrote Puppet. http://madstop.com/2008/11/01/a-short-history-of-puppet-pt1/ http://madstop.com/2008/11/06/a-short-puppet-history-pt-2-cfengine/ Project homepage http://projects.puppetlabs.com/projects cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

[Server-devel] Server performance feedback and testing suggestions
In our PNG deployment we have only just got the system up for testing due to late delivery of most of the infrastructure eqt (we had the laptops so were able to complete the initial training); - 250 XOs divided into six classes G3A - G5B and all 15 teachers - One eBox fanless VIA server with 1GB RAM (non-expandable). We had planned two (one for G3-4 and one for G5+) but vital eqt did not show up in time so we are managing with one. - Campus wide wireless network, solar powered, using a ratio of less than 30 XOs per AP. - 1Gb switches used throughout - 1:1 use of 15W thin film (GoldPeak) panels with DC Share cables for the laptops. No power in this school. I have questions about power management for the server, and feedback on server performance. Layout is 3 x single storey double classrooms (G3A, 3B... 4A, 4B...etc) in line, separated by about 15m. The server is situated in a parallel line of classrooms about 6m to one side. We use some centrally located solar power supplies with POE. The whole system is DC powered and we use digital; timers to turn things off when not needed to save power. However the system provides good access for at least 15 hrs per day. (Advice on power management): I would like suggestions how the server can be safely turned on and off automatically. I guess auto off at an agreed time would be easy, turning on might be hardware dependent. Or can we put it into sleep mode when not needed (10pm-7am) and have it running 24/7? With solar power one has to be efficient as possible. If it is run 24/7, we'd like to know how a timed daily reboot can be activated, and whether that is a good idea or just leave it on. (Advice on server performance and testing suggestions): We only have 2 days to test the full system due to the crazy logistical issues that have plagued us. Yesterday we had it all running with the students in the classrooms, logged on to the server OK. They are segregated into 3 courses at the moment (G3, G4, G5) with about 60 students per course. However in the test yesterday it was out of school hours and only maybe 30 students per course (Grade) were present. We observed that browsing the server, both with site files and public folders (such as Schools Wikipedia and the heavier UNESCO ASEAN SchoolNet series of flash animations) was generally working good and the server as responsive. Moodle admin (such as adding users to courses) was working very responsively. So generally the impression was that networking was functioning well over the entire campus. However, we noticed that collaboration was not working well. XOs could not see all members of their course in neighbourhood view - it seemed to be taking a long time to populate the view, and you could see some dropping out occurring - XOs that were on and connected, suddenly disappearing from view on a neighbouring XO. Likewise, sharing activities was almost universally not working - no icon displayed on the course members neighbourhood view. This contrasts with the good responsive and reliable browsing. In this test, we were using presence service split by course, with the students added as students and the teachers of those grades added as teachers. No-one was given site roles. The teachers were also members of another course teachers intended to allow collaboration between the teachers in different grades. We would like some feedback on what could be the issue. Is it the low power server with only 1GB RAM? But we only had a maximum of about 90 students divided into the three courses online yesterday. Could it be some inefficiency in the networking? But browsing was working well. Could it be that Moodle is broken in some respect? But during training we were experiencing no issues with collaboration with the teachers. What data , logs can we collect to analyse the performance and feed back to this list? Thanks.

Re: [Server-devel] Turn Editing On missing and joining multiple courses
Martin, My request is about the Front Page. In courses it is clear how to manage editing. On the Front Page only the first XO seems to be able to create global links to public folders and site resources (the menus that become editable through Turn Editing On). It may seem a point of detail but what happens if the first admin XO becomes unavailable for any reason? We are told that logging on as administrator is at your own risk as it might break Moodle. As the persons who would be required to log on as administrators would be the teachers only newly introduced to computers, I think we need to follow safe guidelines.
