Mono on OLPC (One Laptop Per Child) device update

Hi guys, A new official version of the XO Operating System is came out some days ago, the 767 build. Unfortunally the mono activities doesn't work on this environment. After some work to understanding the problem (because if I try to run it from Terminal activity using sugar-launch it came up) the bug is now fixed. The problem was related to the rainbow security model implemented on XO. This version of rainbow do not create the standard input and output file handles so the application hang-up. To fix it you need to modify the script that launch the activity to add a redirection from and to /dev/null. After this you have your activity ready to run again. Here you can see the wiki page on with the script updated. Happy hacking

Mono on OLPC (One Laptop Per Child) device update

Hi guys, several months went by without any post, but I didn't remain idle. During this time I made a lots of things but now I'm glad to post an update to sugar-sharp. This update will let you to use the datastore service that Sugar makes available to store your data. The datastore data are used by the Journal and can be integrated with the school server. This version is a very low-level API because it's a one-to-one mapping with the DBUS services. In the next version I will create a new class to allow you an easier way to access to the data on the datastore. Any suggestions are welcomed. You can find the instruction about compilation of mono here, and here you can find the source code. Happy hacking to all

GBrainy for OLPC v0.50

Hi everyone, my little contribution to the OLPC and Mono is not finished yet, so in the last days I tried to port the new version of GBrainy to the OLPC Device. GBrainy is so nice that the OLPC version needs to be updated. You can find it here. The original web page can be found here. Thanks to Jordy Mas for the original code.

Mono on OLPC (One Laptop Per Child) device

After a lot of time I'm finally releasing the first version of Sugar assembly to "sugarize" a Mono application. This assembly is needed to integrate a Mono application with the Sugar environment so it can run on an OLPC device. This version allows creating applications that use GTK# forms created programmatically or by a Glade resource file. Additional work remains to be done to support new widgets and integrate with Journal/Datastore to enable using all of the OLPC resource. A specific wiki page has been created on wiki at this address. I have ported two applications to the OLPC device: GBrainy and MonkeysMemory. The first application is an interesting application to "improve" your brain, while the second one is a simple "Memory" game that I wrote to play with my children. Again I created some specific wiki page on wiki, one for MonkeysMemory and one for GBrainy. Here are some screenshots to see these applications (oops, activities) in action:
