That's a good idea, thanks. I haven't decided what to do about OpenOffice yet -- at the moment we don't ship it, but do ship abiword and gnumeric. The options for it look something like: * just add the openoffice.org Fedora packages for GNOME. (How much disk space would that use?) To provide the somewhat equivalent programs in full version OOo in comparison to OOo4kids: openoffice.org-writer openoffice.org-calc openoffice.org-draw openoffice.org-impress a yum install takes up ~300 MB, though I believe some of that is the actual download. * just add the Ooo4Kids activity for Sugar. * just add the Ooo4Kids activity for Sugar, *and* find a way to make the same activity launchable inside GNOME. This would need Ooo4Kids to be useful for older kids as well, since they're the target audience for using GNOME instead of Sugar. The OOo4Kids activity is here: http://activities.sugarlabs.org/en-US/sugar/addon/4241 (100MB) Claudia and I have been working with OOo4kids for the past few days and I really like it in both Sugar and Gnome and on my own Mac. (It can be launched in Gnome through /home/olpc/Activities/ OOo4Kids.activity/resources/program/soffice) It has very nice icon driven interface and has much of the functionality I would expect in typical office applications. I like the idea of have a single application that is usuable in both environments to reduce the overall footprint. Could we have it linked into the Gnome Menu? The one question I have is in regards to localization. Can we have one bundle that supports localization, i.e. changes default language according sugar/OFW values, or would we need different bundles?

Re: About 8.2.2
Philipp - I would prefer not to speculate about what is happening or not happening in various locations; if small XO situations want updates they can obtain developer keys for them. I'm not aware of any requests from Cambodia for software updates they don't have, or for signed builds. It's important to remember that we added considerable support for signing autonomy to the XO-1 and OFW, in order to avoid the perpetual unfunded mandate of having OLPC provide signed builds and related signature tasks. - Ed On Dec 2, 2009, at 2:49 AM, Philipp Kocher wrote: > Hi Ed, Martin > > What is the plan for the Fedora 11 build for XO-1, will OLPC sign such a > build or is 802 the last build signed by OLPC? > > I don't think one of the two options is a good solution for small deployments > without a tech team. > > I think for the case of Cambodia with many small deployments (educational > NGOs got XOs donated from G1G1/OLPC or other donors), no signed builds > probably means that the XOs don't get updated anymore. > > Best regards, > Philipp > > On 12/01/2009 08:04 PM, Ed McNierney wrote: >> Philipp - >> >> An OS image signed by OLPC can be booted by any XO-1.0 laptop in the world, >> except for those which have been reconfigured by a deployment to only >> respect software signed by other security keys.

Daniel, I've not got such documentation, could you tell me where can I get it? "Also - what does the firmware on the card do with that? Could it be overwritten by a DCW algorythm?" -Martin Martin, No idea if that happens, I've only read such parameters since they were used also by the XO1.0 and assumed that they remained there for the XO 1.5. If I can get a copy of the documentation I may be able to understand a little bit more about this.

Ok, and what about the documentation? Are you sure that a value of 31 actually means 31 slots? On other wireless hardware I have worked with, this was not the case.

Re: XO 1.5 - CONTENTION WINDOW
Sure, I'm looking directly at the registers in the XO 1.5 B2 laptop. The process I follow is the following one: # mount -t debugfs null /mnt # cd /mnt/lbs_wireless/eth0/ To read register 0x # echo 0x > rdmac ; cat rdmac MAC[0x0] = 0x0033fa05 I've read the following registers: 0xA0A0 - CWMin queue 0 0xA0A4 - CWMax queue 0 0xA0A8 - CWMin queue 1 0xA0AC - CWMax queue 1 0xA0B0 - CWMin queue 2 0xA0B4 - CWMax queue 2 0xA0B8 - CWMin queue 3 0xA0BC - CWMax queue 3 Now, this are the four queues I've read, and they have the values: CWmax = 31 CWmin = 7 The eight registers that follow this ones have the exact same pattern (7 31 7 31). That's why I mentioned eight queues (but I might be wrong and those other "queues" could be backups of the first ones).

Re: XO 1.5 - CONTENTION WINDOW
What I was expecting was to have CWmax closer to 1024. What I think happens when you set CWmax to 31 is that -as you have more and more machines trying to compete for the medium- you could be having more colisions -since they would wait less time slots to tx and collisions would be more likely to happen. When you set CWmax to a higher value you prevent this situation. Of course this is for a higher number of machines using the medium. Maybe I'm wrong but this might be optimized for a certain number of machines. If so, could you tell me for what number? (not exactly just an estimate). Thanks Martin.
