*Software:* Chris Ball notes some great community contributions this week: * Cortland Setlow wrote a script that allows us to support "cloaked" wireless access points without turning off the rest of our collaboration stack. Moreover, he wrote it without actually having access to such an access point himself. Kudos! * Wade Brainerd conducted a marathon coding session on the "wikiserver" work mentioned last week (http://wiki.laptop.org/go/Wiki_server), managing to port the webserver to the XO and turn it into an activity. Chris Ball produced an archive of the Spanish Wikipedia that contains the text of the top 35,000 wikipedia articles as ranked by the number of "incoming links" to each page. The full activity, containing the snapshot, is 80M in size. Wade and Chris plan to add 20M of local images before releasing the activity -- help is needed coming up with and running an algorithm to select the images to include.
Guillaume Desmottes: - Lots of improvement in Gadget. Most of the activities and buddies queries are not implemented. It properly manages presence subscription. - Started to implement pubsub notifications support. - Worked with Morgan on improving 1-1 chat support in the Chat activity. This allow conversations with non-OLPC users. Dafydd Harries: - Helped Guillaume join in on Gadget development and reviewed changes by him. - Worked on making Gadget support the kind of queries the mesh view needs. Eben Eliason: * Created preliminary mockups for a friendly Sugarized object chooser * Created preliminary mockups for the long awaited "Group" interactions * Began discussions with our Season of Usability student who will assist in designing an interaction model for handheld mode After a few more days with the mockups, Eben intends to export sequences representing some use case scenarios, which will be posted to the Designs page on the wiki for comment. Andres Salomon: - updated master to 2.6.26-rc1 - branched 'testing', merged it with 2.6.25.2 - worked more w/ upstream. worked with Richard Smith on battery issues - discovered an upstream lxfb bug, still working on it. Tomeu Vizoso: - worked on alternative implementations of Datastore features and discussed with others how we can go forward in the Datastore front. Morgan Collett: - is working on changing presence API for activities; how can we better specify the dependencies between activities and specific Sugar versions? Most activities he touches in this release cycle will then not work on older builds. Also we need an effective way to track activity release numbers (Chat-37) for stable and developer releases. Dennis Gilmore: - reports that thanks to Blake Setlow we have an image that boots and by putting an xorg.conf file in place X will start. However there the keyboard and touchpad don't work. - An external keyboard failed to work but an external mouse works. - The patches for upstart need some work. We will also want to look at initscripts and customise for our needs, hopefully starting the X Window System very early in the boot process. Going forward Dennis would like to only accept packages built in Fedora's koji. This gives us two things. - First: its easy to recreate the rpm if needed - Second: it will ensure that everything will be available to children to use on a desktop or laptop that is not an XO. - It will also make it easier for people to develop activities. sugar-jhbuild against GIT should seldom be needed, with the possible exception of core sugar developers. We should ensure that packages are in all distros and have developers use those. Fedora, Ubuntu/Debian packages are usable now. Michael Stone: * Worked with Blake, Mikus, Dennis, Marco, and Christopher Aillon on upstart and xulrunner-pyxpcom for olpc3/F-9 rebase efforts. * Released rainbow-0.7.12 for testing which should make it easier to create activities from libraries that expect $HOME to be writable. This release has also contains a work-around for #6797. * Involved Daf in "Network Principles" reviews, inquiring about the state of our Process One contract, and arranging a procedural follow-up with Robert McQueen. * Analyzed Presence Service and NetworkManager maintenance problems with Morgan, Scott, and Kim. * Supported Denver Gingerich's testing Andres' 2.6.25-series kernels with encouragement and with an account on teach. * Spent a few hours on a minimal MouseKeys jumpy-touchpad workaround which yielded excellent prior art. (Thanks, Paul Fox & "scrub" http://www.olpcnews.com/forum/index.php?topic=1996.msg19390) Simon Schampijer: - Has been working on the control panel. Checkout the branch here: http://dev.laptop.org/git?p=users/erikos/sugar;a=summary. - For the timezone feature to work you need to apply this patch to sugar-toolkit: dev.laptop.org/~erikos/001_timezone_control.patch<http://dev.laptop.org/%7Eerikos/001_timezone_control.patch> Scott Ananian: - Quanta mfg-data import actually went pretty smoothly this time; hopefully the surprises will stop or slow down to allow for autmoation. - Wrote down how Olpcfs interacts with external storage devices. - Clarified some confusion on network principles; worked out some special cases with wad to add to the documentation. - There's a number of initramfs-related things to do: * customization key should support .i18n, .kbd, activation/developer keys * build quanta .img from customization key (hopefully using same codebase); we need to document a checksum procedure for them as well * modprobe usb-storage to allow modular USB. * bundle olpcrd w/ kernel (build system integration) * partition support Scott is hoping to tackle all of these in a batch while the code is in my head; if you've got additional desiderata, tell him while he's knee-deep in it. *Power:* Richard Smith: - Assembled a working multi-battery charger with enough parts for 9 functional channels. This includes modifications to the battery retention snap that solves the "too hard to remove" battery problem. Starting next week it will be placed out in the 1CC garden for people to use. Richard would like as many people as possible to use it to charge their batteries so he can begin to gather performance data. - The next issue is to decide what to do for fixing the retention snap on the upcoming test build of 50. Make the parts and then hand modify them or re-open the tooling. A new tool will mean a 4 week delay. *School Server:* John Watlington: - Released a new build of XS School Server software (build 163) this week which fixes some problems with an earlier bug-fix release (build 161). - Build 163 is recommended for all new installations. *Testing:* Gainnis Galanis: - has developed several Network testing scripts to collect and display information about the network configuration, telepathies and their status, the neighbor XOs and the forwarding tables. For details see http://wiki.laptop.org/go/Network_Resources. With the help of Michael Stone these scripts will be in the next joyride. Some of the data was taken from http://wiki.laptop.org/go/Test_Network_Configuration, which he also updated. - Yanni and Kim have also been working with the NYC team to try to meet their short term needs. Yanni created a script for associating to a cloaked AP. The script is available at http://wiki.laptop.org/go/Network_Resources. Polychronis Ypodimatopoulos: - reports the latest results from his Cerebro's (http://cerebro.mit.edu) scaling properties. A 65-node testbed was used with build 703, Q2D14. The NetworkManager had to be disabled in order to stabilize the behavior of each XO's wireless interface. - Results look very promising and can be found here: http://wiki.laptop.org/go/Simple_mesh_test_%28Cerebro%29. He was able to share a chat session with 65 laptops. *Support:* Adam Holt: - continues to work donor services questions as well as helping out those who are building up repair shops and repair skills such as Cortland Setlow (NYC) and Mel Chua (Cambridge/Boston area). - interviewed and hired two temporary support specialists to take on the final weeks of G1G1 calls and emails as we start to close down this program. Sara Lesko and Michael Taylor are now in Adam's office, which is the temporary location for the 'call center'. - re-initiated a project to build an asterix based call center with an automated response system. Emily Smith: - worked on about 75 new tickets this week, closing out 95% of the 90 that were open from previous weeks. - continues working the replacement, reshipment and refund requests. Kim Quirk: - worked with various deployment teams to address their longer term feature requests - provided activation server management to allow deployments to get their own developer and activation keys - continues to work on issues with the Spare parts program with Brightstar; as well as in discussions with volunteers to help create more business-like model for repairs. - answering pre-sales requests for technical information, network configuration, as well as bug fix requests from Peru - Urdu keyboard change requests, and on-going discussions to get a new Turkey keyboard into production. - Production issues from Quanta required testing and debug for Haiti and Ethiopia laptops. Thanks to Arjun Sarwal and Bernie Innocenti for their help. *Sysadmin:* Henry Hardy and Dennis Gilmore have installed the 9 new disks in the Coraid 1521 disk system and built a RAID5 array on the new disks. The parity disk is still being created. The new filesystem is mounted on grinch as /mnt/filer2. Henry and Richard Smith are continuing recovery efforts on the OLPC server in China. The file system was apparently damaged in a power outage severely enough that it is questionable if it is bootable in its current degraded state. We have ordered and will be building a replica of the server at 1cc in order to construct a bootable image we can physically mail to China so the server can be safely rebooted.
