Without something like that, an upgrade to a new format in a large school would swamp RF for days... Sounds good, I guess you can do the reorg with hard links in the same script where we had the metadata exported to json.

UNESCO: How Do We Guarantee the Presence of a Language in Cyberspace?
Hi Everybody, This is from the OLPC-sur list. UNESCO has recently released an English version of its publication on languages in cyberspace. It is also available in French, Spanish, Russian, and Portuguese. Here is the link to the UNESCO announcement which has a link to the PDF copy of the book. http://portal.unesco.org/ci/en/ev.php-URL_ID=28065URL_DO=DO_TOPICURL_SECTION=201.html Caryl ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Small DNS questions.
Scott, I've been conducting some thought experiments with the imaginary DNS server you describe in http://wiki.laptop.org/go/Network_principles#Name_resolution and I've developed a couple of small questions which I'd like your advice on, e.g. a) When multiple links are present, does the DNS server synthesize an RR for every link? b) Presumably the DNS server should report itself as non-authoritative for everything except the local hostname(s)? c) Presumably the synthesized RRs should be non-authoritative except when they answer the local hostname(s)? d) How should the TTL of the synthesized records be set given that the records are link-dependent? (on a mobile device?) e) When, exactly, should our DNS server synthesize RRs? Some possible choices: always, when you can't get any other results, when you didn't find NXDOMAIN, configurable __ Thanks, Michael P.S. - People who are unfamiliar with the ideas and questions in this note who would like to contribute to the conversation should probably spend some time reading RFCs 1034, 1035, and 2460 and Scott's Network Principles document. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Notes from an impromptu 8.2.1 Release Mtg.
The main conclusion that we reached after we updated http://dev.laptop.org/report/38 was that staging-9 [1] needs some testing! In particular, it's got long-awaited new wireless firmware and wifi kernel drivers which means that we need to know whether it still associates with your crazy encrypted access points. :) [1]: (http://xs-dev.laptop.org/~cscott/xo-1/streams/staging/build9/devel_jffs2) That's Build 9, 1352 from 6-Jan. What firmware should we be testing? I'm using Q2E24. There are several later versions, but I didn't see anything that looks interesting in the web pages. I don't remember any please-help-test-this messages but I could easily have missed one. The latest version is Q2E28. I'm reasonably sure that it didn't get much testing since I just fixed a typo on the wiki page in the URL to download the bits. Anyway, most of the testing below was done with Q2E24. I've updated to Q2E28 and a quick test didn't show any changes. I have an early B3 board in a B2 chassis. So any or all of this may be a wild goose chase. It used to work reasonably well. I think It was the last major release. From the bits on my hard drive, that looks like 759. -- Several quirks: 1) During setup, I normally ssh in via an USB Ethernet dongle so I can run Wpa.sh. (I have a long password so select/stuff is much more convenient than typing it in.) DHCP didn't work automagically like I expected it to. I didn't investigate. ifconfig by hand worked. 2) For me, the new wireless is a step backwards. My setup used to fail occasionally. Now it connects occasionally. After it connects it seems to work OK. I'm using WPA version 2 on a Linksys WRT54GL There are usually 2 to 4 other systems visible. There are no other XOs nearby. (At least none that I know of.) I realize that occasionally isn't very precise. I don't have hard numbers. With the old system, roughly 9 out of 10 reboots automatically connected. I had to go looking for one that failed. (Normally, I don't reboot very often.) With the new code, I've rebooted 10 times so far, but I haven't see any of them connect automatically. I have seen the icon blinking while it tries. Usually it works when I manually poke connect. I got a bit frustrated the second reboot when 3 pokes in a row didn't work. At least once, the blinking icon stuff got confused. Maybe because the underlying control code was confused. I saw Mesh-11 blinking for a long time after I did a manual connect... Is there anything I can do to collect useful debugging info? 3) I have now seen to the crazy-cursor symptoms that have been discussed here quite a bit. It's possible that it's been there all along and I just haven't noticed it before or I didn't use the cursor pad enough to tickle it. This time, I discovered the Implode activity and I have been playing with it. It uses the cursor a lot. I've seen one time where it was nasty enough to make the cursor totally unusable. The cursor just kept jumping to the upper right corner. I tried rebooting. That didn't fix it. A power cycle did. That could be a wild goose chase. Even when it isn't a total disaster, the cursor is still very hard to use. The problem seems to happen when I lift my finger off the pad so I can move it over and set it down to continue a long move. Yes, I could be being sloppy and moving before I lift, but I've been working/playing with it enough that I don't think it's me, or if it is, other normal users will be totally frustrated. Sometimes it jumps to the lower left corner. Again, this is a B2 chasis with a B3 board. If the cursor pad stuff has changed I apologize for the noise. -- These are my opinions, not necessarily my employer's.

[Server-devel] updates
Hi Martin: latest re-roll of anaconda, srpms, rpms and patch used, updated mkusbinstall for the XO at: http://members.shaw.ca/jvonau/pub/anaconda/ - finds kickstart file without asking where it is... - loader doesn't copy stage2 to RAM - fix compile error re: MD_NEW_SIZE_BLOCKS(size) - added support for method=hd:LABEL=XSRepo at the boot prompt This allows us not to ask where the install media if the usbdrive is labeled as XSRepo and passed the above string. - added support for mmc cards (for the XO) in loader. This is incomplete, loader now finds the CF card on the XO but is unavailable to partition and thus install to it. F10 has the same behavior, I filed BZ# 481441. Hope they fix the issue before I have to dig it up - updated mkusbinstall added the labeling of the usbdrive for the above method and creation of /boot/olpc.fth for the XO.
