Re: from Peru, sugar in DEBIAN
You can also try to download activities from activities.sugarlabs.org. Many will work without recomipiling, just by installing the packages within sugar. Since the debian package for Browse is broken you need to download the file with wget or from GNOME, etc. and then install it within sugar using the terminal activity using sugar-install-bundle.

Re: TamTam
Since TamTam uses Csound internally it is actually easier to use a MIDI keyboard than the QWERTY keyboard. It shouldn't be hard to add, but who is maintaining TamTam currently (and where?). I could help with this. Cheers, Andrés 2009/2/25 Caryl Bigenho cbige...@hotmail.com: Hi Aaron and other music enthusiasts... Aaron asked for info on how to use TamTam.

There are other videos on YouTube you might check also. We really need to do a FLOSS manual for the entire TamTam suite during the BookSprint next August. How about it? We really need someone to do the programming to interface an electronic keyboard to the XO. Shouldn't be hard to do since the XO already can recognize usb keyboards...just something that will convert the signal from the music keyboard to what it would be if the corresponding XO key were pressed. This is such a powerful program with a lot of educational potential. We really need to give it more attention.

Re: How to set up your XO to swap to an SD card
Hi John, Thanks for the info. Are there noticeable performance gains/losses when using an external SD swap partition? Won't adding a line to /etc/fstab make the swap partition be used on startup automatically? Cheers, Andrés On Sun, Aug 10, 2008 at 4:21 AM, John Gilmore [EMAIL PROTECTED] wrote: Have you tried with a swap partition? Swap is robust now on a SD card, immune to suspend/resume and power cycle. External swap area sounds cool. How does one set it up? I'll give it a whirl. Use a recent joyride. Get a throwaway 1GB SD card. Available for $3-$20 depending where you go. I say throwaway because swapping to it will tend to burn it up faster than its usual lifetime for photos and such. You will still be able to use half a gig on the card for file storage; the other half will be for swap space. Plug it into the SD card slot on the XO. You'll have to keep it plugged in the whole time while you're swapping to it; you can't remove it the way you remove a USB stick or a non-swap SD card. If/when it starts to fail after a few years, you can copy any still-interesting user files off it, throw it away, and put in a new $1 1GB SD card (or something larger). Go to a terminal (either the activity, or Ctrl-Alt-F1). Become root. Type mount, make sure the SD card is mounted at /dev/mmcblk0p1, in a vfat filesystem. Go into the Journal, find the SD card hiding behind the Frame at the bottom, hover over it, pick Unmount. Go back to the terminal. Type mount, make sure /dev/mmcblk0p1 is not mounted any more. Type yum install parted since the partition editor is not in the distro any more. Run /sbin/parted /dev/mmcblk0. Type print to see the current configuration. On mine it looked like this: Number Start EndSizeType File system Flags 1 127kB 1018MB 1018MB primary fat16 Type resize 1 0 512 to shrink this filesystem down to 512MB. If it asks you whether to use FAT32, just say no. Then type mkpartfs primary linux-swap 512 1018. That'll make a second partition for swapping to, and format it as a Linux swap partition. Type print and it should look roughly like this: Number Start End Size Type File system Flags 1 32.3kB 512MB 512MB primary fat16 2 512MB 1018MB 506MB primary linux-swap Type quit. Now you're back to the shell. Type /sbin/swapon /dev/mmcblk0p2. You're done. The Hal daemon is smart enough to mount filesystems when it sees an SD card appear, but it's not smart enough to start using freshly available swap space. For the moment, you'll have to do /sbin/swapon /dev/mmcblk0p2 each time after you reboot the XO. Similarly, it won't do the /sbin/swapoff if you want to eject it. I'm sure somebody will eventually come up with a Hal script or something to automate that part. You can see how much swap space you have / are using by running top in a terminal window; it's about the fourth line down.

Re: Questions, OLPC-Caldas
Hola Carlos, man is man. You can install it with yum install man For ssh you can set the password using passwd (either for root or for the user). ifconfig is ifconfig, but on fedora, the /sbin directory is not on the ordinary user path, so you must use /sbin/ifconfig, or be root and use ifconfig.

Since the OLPC uses the float build it uses a different file (this setup allows a system to have both floats and doubles version of csound without conflicts). Hardcoded paths starting with /home/olpc were changed too but it still does not play any sound - the graphics are stunning though! :) The version of csound for the XO is a modified version which among other things uses the alsa output module by default. The normal version defaults to portaudio. You would need to check whether csound is actually producing sound on your machine. You can use many of the manual examples (e.g. oscil.csd), which are configured for realtime audio. If csound is producing output tamtam should too. I tried it some time ago on a debian machine, and it worked fine. csound is 5.08.0 do you know if that should be OK? yes, the current version of OLPCsound is a cvs version a little later than the official 5.08, but there should be no important changes.

I tried a while ago and it worked and from pippy as well, but the latest package does not. So it is may not be a tamtam issue after all. New packages have made into debian testing. You might want to try those. Also remember you need to set the OPCODEDIR (OPCODEDIR64 in your case) so the csound library can find the plugins (plugins in csound include opcode plugins and realtime output modules).

Activity Icons gone
Hi all, I've suddenly lost all the icons for activities, after trying to update the Develop Activity. I deleted the entry for the older version from the journal, and then fired up the newer version. I did notice before firing up the new version that the icon for the develop activity was not there but the space for it was there and if I hovered over it, it was still called Develop. When I installed the new one, there were two icons for develop, but everything seemed normal, and the Develop activity ran OK. After reboot, I have no icons for activities. Any ideas?

Re: Why can't i access /dev/dsp or /dev/snd on my XO
How about just reenabling OSS emulation? It's included in alsa, so it should be no problem, maybe it's just a case of modifying modprobe.conf. I second Victor's suggestion for the csound api, though. I wonder if there is a major impact on performance by using it? Cheers, Andrés On Jan 18, 2008 5:24 PM, victor [EMAIL PROTECTED] wrote: What exactly is the problem with the alsa driver? Csound works OK with it. Replacing it with OSS will require us to write a new IO module for Csound. Without Csound, audio and music on the XO will have to be completely re-written. IMHO, developers wanting to use audio on the XO should ideally use Csound and its Python API. That's why it's there. As far as I am concerned, having developed audio apps for Linux for several years, Alsa is much better and more reliable than OSS.
