I don't believe there should be any issues as the Mac Minis are well supported on Fedora which is what the XS is based upon. The Mac Mini servers with 2 disks would be good as they provide some resilience. The other device you may want to look at for low powered devices are the eeeBox devices which are atom based so will use even less power.

I want it on idle :-) i figured. :-) unfortunately kernel console blanking was never tied to the dcon -- i think it's one of several issues with bare console use on the XO. (the console has never been a priority.) you can install olpc-kbdshim and olpc-powerd, and adjust the powerd config to never dim and/or blank the display without ever suspending. the fedora F9 packages should work for this. paul =- paul fox, p...@laptop.org ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] Schools Wikipedia
Hi, The current Wikipedia activities already work as web servers on the XS, and require much less space due to the content being compressed -- for Spanish, 25,000 articles and 3,000 images in 100MB. David pointed out that this isn't actually documented anywhere. :) Here's the HOWTO. On a fresh XS, for English WP: $ wget http://dev.laptop.org/~cjb/enwiki/WikipediaEN-4.xo $ unzip WikipediaEN-4.xo $ cd WikipediaEN.activity/ $ python server.py en_US_g1g1/en_US_g1g1.xml.bz2 4567 .. then you can browse to http://schoolserver:4567/ on an XO or other machine. For Spanish, get http://dev.laptop.org/~cjb/eswiki/Wikipedia-11.xo and replace en_US_g1g1 with es_PE. - Chris. -- Chris Ball c...@laptop.org One Laptop Per Child ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] XS on Mac Mini
It would be interesting to hear what the remaining hurdles are. The Kirkwood ARM processor in the guruplug should be well supported by the current Fedora release --- this may be mostly a matter of moving to an F12 base. My main concern with the guruplug would be the external USB disks (overheating or disappearing). The same hardware should be available in a NAS (networked attached storage unit), wrapped around a hard drive in an enclosure --- the Marvell ARM is a popular choice. We have good relations with Marvell, and have been encouraging them to get support for their ARM processors upstream for several years now. wad On Mar 2, 2010, at 12:27 PM, Sameer Verma wrote: On Tue, Mar 2, 2010 at 6:09 AM, Caroline Meeks carol...@solutiongrove.com wrote: I was talking to Timothy Falconer who is planning deployments in Haiti and Patrick Giagnocavo founder of Zill.net our sysadmin and hosting company about this.

I installed olpc-kbdshim from the repo and then http://dev.laptop.org/~pgf/rpms/olpc-powerd-9-1.fc9.i386.rpm. Tried editing /etc/powerd/powerd.conf to make the screen blank, but I guess I don't know what I'm doing cause it's not working. In my particular situation, I usually just make sure the XS on XO is booted up and online, then ssh in from another machine. So the ability to turn the backlight off at will would be great. When I have a screen at all, that is. I've been messing around with XS on XO on a couple of XOs that have been stripped for parts cause of one issue or another. But that's another story.

[Server-devel] Manual for install XS over Debian
Somebody tell me that the developers of XS use Debian. I'm interested in a manual of how to do for use a Debian server for do a implementation in this way.

The ejabberd-xs rpm (derived from the ejabberd rpm) is arch-specific , even though the .beam files are probably right for the Erlang VM running on any supported arch.

On Tue, Mar 02, 2010 at 09:00:50PM -0600, Anna wrote: I'd appreciate a command to blank the screen. Your subject line mentions the backlight, and blanking the screen is potentially a different task. I've tested an XO-1 with build 802b1. If you mean the backlight, you can manually control this from a shell command or program like this: echo 0 /sys/class/backlight/dcon-bl/brightness or echo 0 /sys/devices/platform/dcon/backlight/dcon-bl/brightness Change the 0 to 15 for full brightness. With the backlight off, the screen image should still be visible. You can manually turn off the screen and hide the screen image with this shell command: echo 1 /sys/devices/platform/dcon/sleep But it doesn't turn back on automatically. You can appear to lose control this way; you can restore it to normal with this: echo 0 /sys/devices/platform/dcon/sleep The text console does idle blank after a while, though without turning off the backlight. It is possible to initiate screen blanking manually using code that calls ioctl with TIOCLINUX and TIOCL_BLANKSCREEN but like the idle console blanking it leaves square brackets on screen. The other three modes of VESA blanking that the kernel can do (TIOCL_SETVESABLANK) don't fare any better than the default. Two of the modes do the bit rot melt down effect on the display. It is also possible to manipulate the blanking timers using escape sequences sent to /dev/tty1 ... but again, we haven't integrated the VESA blanking feature of the kernel with our DCON and backlight. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
