Scott Hi Scott, unfortunately, there are a few problems running existing Python code with IronPython because the glue level between Python and C library is managed in a different way. Python requires a specific C library to handle native calls, while IronPython uses PInvoke to do this. I'm now trying to implement a class library to run any mono program on Sugar, but being compatible with Python class libraries is not a priority at this time.

Im working on it in a way though to run more effficiently than running as a normal JIT and instead working on a compiler of IL that can use the mono libs. We already have quite a bit working. Sorry Chad, I don't understand what you're doing. Is it like the AOT (Ahead Of Time compiler)? If so, I know that this function works in the mono compiler. I never use it because, when you use the AOT option to compile a program, the metadata are stored the usual way, but the native code for all the functions is also included in the final binary, so the size grows. Ok, you can save the startup time the JIT compiler, but it is generally fast and called only once per each method, do I don't know how much performance improvement you get.

Re: Walter leaving and shift to XP.
With a lot of friends we are create a legal association called OLPC Italia to allow the Italian citizens to buy OLPC using G1G1. For us the most important thing is the Educational Project but sell the XO with XP is not an educational project. We accept Sugar as core of the user interface but which are the real benefits to have Sugar on Windows instead to have Sugar on Linux? If is possible to use normal windows application on top Sugar+Windows the educational project is broken because the developers what need to write a program (program not activity) write it on windows because in this manner one PC with windows can run it, and XO XPzed too so why write code for sugar? In this scenario Sugar is dead and OLPC became a Laptop organization (for me of sure). If, otherwise, Sugar XPzed is not able to run normal windows application I not understand why abandoned Linux to Windows but is the only choice to maintaining the original aim (Not a Laptop but an Educational Project). Regard the problem about flash, we need to thing that XO is not thing to be use as normal PC for normal user so we simply need to promote the creation of education website that can be viewed from the XO. Last point is the need of clarity. If OLPC turn to this direction we are not interested to sell a PC and prefer to spend our time in other manner. If OLPC not thing to became a Laptop company we ask to understand how OLPC wants to do this. P.S.

I'm seeing the same. As of 2.6.23, if the kernel is configured with support for instruction set extensions, it will refuse to boot without the presence of the flags that indicate support for those instructions. Some digging revealed a patch[1] for qemu that enables 3dnow emulation, but it hasn't been merged to qemu svn. How much do we gain from having 3DNow support turned on in the kernels? If the difference is small, perhaps we could disable it? Is booting xo images under qemu still worthwhile functionality to include, now that there are other options for running Sugar, as well higher[2] availability of XO's for developers? If this path was taken, software such as grub and additional drivers could be dropped in return for free space on the NAND. Having a linux kernel that run at the maximum speed is right for jffs2 image where the target if the real device. The ext2 image, I suppose, is oriented to be used in external device or virtualization system. If qemu, vmware and virtualbox are not able to handle 3dnow extension, since I suppose to be run on more power system like AMD64 or IntelCore3, I think that is better if this option is not enbaled on this image type. If this is wrong, I hope there is a kernel version that can be used on this virtualization tool from the GRUB menu.

I'm running Os X Leopard and want to use qemu to emulate the os and start developing. However I'm getting problems.

Me too. Fortunally I have 2 machine: one laptop with intel and a desktop with AMD so I use the desktop for my test. I already ask about this problem but seems that at the moment only one kernel is build with 3dnow extension enabled. I hope for the next build. Any suggestions? Personally I install a FC9 on my virtualizzazione system and build all the sugar environment to make my test. You can use this way but it is right only if you want develop for XO (I suppose).

767 XO image - Italian keyboard not work
Hi to all, This week I got a XO device with Italian keyboard from Florence Council. I installed the 767 kernel image on it and unfortunally it not works. I (with a lots of external help :) ) identify the problem in a symbol configuration keyboard file, so I fix it on this device. I generated a new image that I can use on my XO B4 (open with development key) but I can't apply to the offical XO (that are closed). Now I work on a script that make the same fix can be executed by the teachers because I not able to sign my image. How send the patch to fix this problem on the official build? Which time for 768?

C or Python would have been much better :-( Actually this implementation is made with mono, yes. But it is possibile to migrate to other environment like C in a second step to have better performance and lower footprint of course. This module can be used for access datastore data as file, on a normal linux box, not only on XS. I use it to get the user datafile from a soas mounting the home.img datafile. For an XS environment is it possible to get a linux executable so not all the mono stack is necessary to run it. Only few shared library need to be used. This is a cool project, and I am sure it is interesting and useful outside the Sugar stack itself. But somewhat ill-suited for building Sugar and XS tools -- maybe I had my hopes up on something it wasn't meant to be :-( This project not start to access the datastore files, but implement it was easy, so I do it. Of course the target is not XS but the normal linux desktop with soas. In this case you simply plug the stick, mount the image and access the datafile. Normally linux box have mono installed, so I think that is not a big problem. The only special dependency is mono-fuse library that can be not available on all distro.
