Re: olpc-update and 10.1.2

It sounds like olpc-update will take a lot of flash space. Maybe the 10.1.2 notes should say how much you'll need. Will the program tell me there's not enough room? Takes about 350Mb, but it is not practical to explain exactly how much space is required, since it depends on too many factors (other previous olpc-updates in particular). Understood. I had 358MB free on my xo-1 and that wasn't enough. My first `sudo olpc-update --usb` failed with a string of errors, after it exited I had only 16MB free. BTW, Mb means Megabits, you mean MB. Yes, if there's not enough room it stops, and after clearing some room I removed the WikiBrowse activity and some large collections (maybe the release notes should have pointers for how to do this) to free up about 110 MB. it can be asked to continue from where it left off. I'm not sure what you mean, but I simply repeated the command and despite all its temp files and symlinks in /versions, it completed. Now that's good softwarin' ! The next problem is Software update wanted to install 218.8 MB of stuff and I had only 77MB free. I unchecked Wikipedia and WikipediaEN (WikiBrowse Spanish and WikiBrowse English) to save space and updated. So I think the Release notes should say [upgrade] requires roughly *450MB* of free space. And change the second part to be and if you install all the latest activities, Software update downloads about 350MB of material if that's what you are referring to. I found a few minor glitches which I'll e-mail or file Trac tickets, but the big problem I have is after Software update none of the new activities showed up in the Home screen in the Favorites ring or List view, and the List view shows the old versions for activities, e.g. Browse 102 not 110. Is this a known issue? All the new versions are sitting in ~/Activities, so I'm not sure why the Home screen has stale info.

strange behavior of 'rm'
I experiment with manually adding/deleting Activities, then restarting Sugar. Sometimes I've seen obsolete activity-versions being listed in some sort of snapshot recorded in shell.log. I've empirically found that I can lessen this by deleting ~/.sugar/default/favorite_activities - and letting the Sugar restart rebuild that file. A couple of times I've found that the 'rm' command I issue for this purpose (e.g., from Terminal, while running as root) appears not to work. [The latest occurred on os353pyg - I don't remember which earlier builds I saw it happen on.] I'm mystified: 0 [~]# rm .sugar/default/favorite_activities rm: remove regular file `.sugar/default/favorite_activities'? y 0 [~]# rm .sugar/default/favorite_activities rm: remove regular file `.sugar/default/favorite_activities'? y 0 [~]# rm .sugar/default/favorite_activities rm: remove regular file `.sugar/default/favorite_activities'? y 0 [~]# ls -la .sugar/default/ total 21 drwxr-xr-x 8 olpc olpc0 2010-08-14 12:24 . drwx-- 3 olpc olpc0 2010-08-14 12:14 .. -rw-r--r-- 1 olpc olpc 9959 2010-08-14 05:41 buddy-icon.jpg drwxr-xr-x 3 olpc olpc0 2010-08-14 05:42 cache drwxr-xr-x 2 olpc olpc0 2010-08-14 05:39 data drwxr-xr-x 5 olpc olpc0 2010-08-14 05:42 datastore -rw-r--r-- 1 olpc olpc 7792 2010-08-14 12:24 favorite_activities drwxr-xr-x 2 olpc olpc0 2010-08-14 05:42 logs drwxr-xr-x 2 olpc olpc0 2010-08-14 05:42 nm drwxr-xr-x 5 olpc olpc0 2010-08-14 05:42 org.laptop.Terminal -rw--- 1 olpc olpc 668 2010-08-14 05:42 owner.key -rw-r--r-- 1 olpc olpc 590 2010-08-14 05:42 owner.key.pub -rw-r--r-- 1 olpc olpc 218 2010-08-14 05:42 terminalrc 0 [~]# mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
NOW! Contributors Program Mtg (#olpc-meeting, 2:30PM Boston Time, Friday)
Please all join us right now reviewing the latest OLPC/Sugar community projects over IRC Live Chat: http://forum.laptop.org/chat Then type at bottom: /join #olpc-meeting AGENDA: * Fast Review of the 4 latest (greatest!) HW/Project Proposals -- please join us advocating for, and/or reviewing shortcomings of these proposals: 1. Squeakland/Etoys Testing - San Jose, CA; Hillsborough, NJ; Bigfork, MN; Champaign, IL 2. GSoC Squeakland Education - Buenos Aires, Argentina 3. Dominican College OLPC Chapter - Orangeburg/NYC, New York 4. * Which projects might you enjoy Mentoring below?! http://wiki.laptop.org/go/Projects http://rt.laptop.org/Search/Results.html?Query=Queue=%27contributors%27 * New projects libraries -- teaching them Community Outreach: http://wiki.laptop.org/go/XO_Laptop_Lending_Libraries 1. Squeakland Etoys Testing - San Jose, CA; Hillsborough, NJ; Bigfork, MN; Champaign, IL http://tracker.squeakland.org http://rt.laptop.org/Ticket/Display.html?id=65375 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 4 XO-1.5s over 3 months Project Objectives: Currently, there is no dedicated user tester group for Squeakland. The education team, being the most active in the Squeakland community have been put to task to test the Etoys program prior to its release. The main objective of this project is to do a rigorous test of the beta version of Etoys against the planned release of Sugar and XO 1.5. 2. GSoC Squeakland Education - Buenos Aires, Argentina http://www.pcs.cnu.edu/~rcaton/ESUG/ESUG.html http://groups.google.com.ar/group/squeakland-education-gsoc-project http://rt.laptop.org/Ticket/Display.html?id=65377 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 1 XOs over 4 months Project Objectives: This project involves developing tools in the Etoys/Squeak environment to aid learners, teachers and developers. I plan to use the XO to test these tools and assure they work properly in the platform. In outline, these tools will be: 1) Etoys Paint Tool: The current implementation will be improved in order to support features like zoom, multiple undo, and a select tool, among others. 2) Graphing of Data: Tiles for creating vertical and horizontal grid lines, major and minor tick marks, labels for axes, and a label for the graph will be created to allow students to graph data they acquire in science and mathematics projects. 3) Input/Output of Data From/To Files: Tiles will be created to allow data from the Etoys environment to be output to a file and for information from an external file to be imported into the Etoys environment. 4) Learner and Teacher Feedback: Tiles will be created to allow formative feedback to be provided to learners and teachers as a student progresses through a project. 5) Better Translation Support: The translation framework would be improved in order to allow different =93.po=94 files instead of one big =93Etoys.po=94 file. 6) Wider Font Support: Currently, Etoys has a set of cross-platform fonts to use. It would be desirable to enlarge this set in order to include nicer fonts. The problem is that loading lots of fonts would make the image too big. Code to address this problem already exists, but it needs to be tested and merged with current Etoys code. 7) EtoyMaker: This tool would let developers select a class name and choose the slots and commands they want for their Etoy. It would then compile all the necessary classes and methods to generate the Etoys tiles, etc. Developers will only need to implement the methods of their class, everything else will be generated automatically. 3. Dominican College OLPC Chapter - Orangeburg/NYC, New York http://acrosstheseas-irie.blogspot.com http://rt.laptop.org/Ticket/Display.html?id=65417 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 10 XOs over 12 months Project Objectives: * Establish a University Chapter in which undergraduate US and Ugandan computer science students collaborate with graduate education students (via Blackboard, wikis, email, etc.) * Collaboration will be charged with creating/programming XO activities in alignment with Ugandan National Curriculum for primary schools. 4. Roadshow In A Box Expansion - Pray, Montana; Los Angeles, California http://wiki.laptop.org/go/Roadshow_in_a_Box http://rt.laptop.org/Ticket/Display.html?id=65468 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 3-6 XO-1.5s over 24+ months Project Objectives: The purpose of the Roadshow In A Box project is to bring awareness of the XO to as many educators, developers, and people interested in deployments as possible. The machines are used for demonstrations, presentations and workshops at conferences and schools, exhibit booths at expos, and
Re: strange behavior of 'rm'
I'm mystified too. But it doesn't happen when I try it on os851 on XO-1.5 ... 1. the file can be deleted by user olpc in Terminal and stays deleted until Sugar restart, (an rm -f works, then an rm -f fails with No such file or directory), 2. the file can be deleted by user root in text console and stays deleted until Sugar restart. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
[Server-devel] Cloning
Are there any recommended ways of cloning an XS installation? We have tried Ping and Reflect but with difficulty. David Leeming ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] Cloning
Hi David, super brief - - get the machine in 'single user mode' (init 1 on the commandline will work) - plug new disk in, setup the partition table, and the filesystems - rsync / and /library to the temp mountpoints - remove hardware-specific files: /etc/udev/rules.d/70-persisntent-net.rules - fixup /etc/fstab to match the UID of the new filesystems - run grub targetting the new disk - move new disk to new machine that will _clone_ the XS so it will keep a lot of identifiers (and all the data) from the original XS. Do NOT use this technique for cloning a base install. Use kickstart/anaconda methods to automate many-machine rollouts. cheers, martin On Fri, Aug 13, 2010 at 6:22 AM, David Leeming da...@leeming-consulting.com wrote: Are there any recommended ways of cloning an XS installation?
