A Live CD doesn't run on anything, generally speaking. It implies a CD which you boot the entire operating system from. To the best of my knowledge there are no Live Windows Sugar CD's.

Re: [Sugar-devel] GSM/CDMA Modems support (part II)

As I mentioned in my last email to devel@lists.laptop.org, there is a real need for a GSM/CDMA usb modem support in our region since thats the most common/available service in rural locations. Have you looked at the project RapidSMS, developed with support from Unicef?

I don't know if there is a PyGTK front end.

Sugar Labs GSoC 2010 Application In
Hi all, Sugar Labs application for Google Summer of Code 2010 has been accepted. Over the course of the weekend, I'll be sending out email flyers for you to send to potential students. I'm not sure exactly on the politics of the situation, but my personal feeling is that we should be quite encouraging of supporting OLPC projects. Two requests: 1. Self-nominate yourself as a potential mentor. This involves a few hours a week could reap huge benefits for the project. 2. Please promote http://idea.sugarlabs.org/ . This means encouraging students to submit ideas then visiting back a few times over the course of the next few weeks. Please feel to contact me off the list at paperl...@timmcnamara.co.nz if you have any questions.

Re: [Sugar-devel] behaviour of F-keys on XO HS

This matches behaviour of normal laptops, including the Dell that I'm writing on. Linux already has mechanisms (once through hal, now through udev) so that when I press Fn+F8 on my Dell, X receives the volume down key press (instead of the Fn+F8 key press), matching what is printed on the keyboard. This convention appears to be changing. My very recent HP notebook requires th Fn button to be pushed to reach the function keys. Everything is reversed. While I don't have the empirical evidence to support a claim that users prefer to have quick access to volume brightness, I think this could be an argument to say that whatever the path of least resistance (in terms of developer cycles) is fine.

If you're unwilling to perform steps 1 and/or 2 as appropriate, please don't expect the bug to be fixed, or for anyone else to even know about it. I know I'm repeating myself here but I find the attitude expressed in these instructions and particularly point 3 troublesome and a continued source of frustration for me as well as other people I've talked to. Even more so I think it's a very clear symptom of the much-discussed disconnect between developers and end-users in the OLPC and Sugar Labs context. The core here is that software developers seem very reluctant to step out of their own comfort zone when it comes to processes and tools (a.k.a. point 3 a.k.a. my way or the highway) yet consistently expect teachers and other XO and Sugar users to do exactly that. I'm not sure of the wider context here, but in general I think it's entirely appropriate to expect that people asking for help do so via the correct channels. It's also appropriate for OLPC Sugar to set realistic expectations. Placing the burden on the user may be the only way to understand what's going wrong with the software. That said, the OLPC/Sugar communities should be very good at guiding new contributors to those channels. Perhaps OLPC/Sugar could create a super simple web form for problem submissions. They would then be triaged (by support gang?) and sent to the correct ticker. That way, new contributions only have a single channel for everything. This leads to the current situation in which crucial information and feedback from these users does not make it back to developers and the broader community. Therefore rather than working on things that users need or need to work reliably (e.g. the Journal) resources are spent elsewhere. This is not the only reasons why the development of pieces of Sugar moves very slowly. The datastore is a complex piece of software engineering. I have no idea how it works and don't think I'll ever able to understand it without someone next to me explaining its operation. The real problem for me, even if I wanted to help with the Journal, is that there is nearly no code documentation through Sugar's core. I find it very difficult to justify spending a few hours learning how a module operates when I want to fix a bug. Yet, this is the situation I face every time. An associated problem for me is that I don't know if my code will break things. AFAIK , there are no unit tests in Sugar's code base. Sugar is actually quite hard to test. Secondly, many of the functions methods are not designed with (unit) testing in mind, meaning it's hard to retrospectively create tests for methods. Testing side effects is annoying. Even if unit testing was integrated into Sugar's development, it's really tough to set up development test environments. sugar-jhbuild has never built correctly for me. Looking through compiler errors trying to identify what's wrong makes me feel like an idiot. The reason I don't look into the hard problems is not that I don't know they exist. It's that they're hard to even start looking into. Tim ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Not at all, but it's a significant one. In my opinion, developers of a product ought to be interested in learning about shortcomings perceived in that product by users. Looking into the original case - we had people on a public forum[1] expressing frustration that yum fails to work among other things. I hope this doesn't come across the wrong way - but are G1G1 laptop owners considered the target market? If a user installs Skype on an XO-1, only to find that it kills the sound, then I think it's okay for OLPC to abstain from taking responsibility. Fora such as olpcnews.com attracts very motivated individuals who experiment. That's great, but once they leave the realm of the product, peer support takes over. In practice, it seems that genuine issues from these comments do find their way to the surface, albeit in roundabout way. OLPC Sugar Labs are now aware that yum doesn't seem to work. Are the correct channels any different than blinders ? mikus I'm not sure I understand what you mean by blinders. Do you mean blinkers? [edit: Wikipedia says yes] In many ways that's true, but the metaphor doesn't transfer exactly. Each channel (Trac, wiki, mailing list, local user group) deals with a different type of problem. They e simply to block unintended knowledge. However, it's likely that some people will be put off - which means that they become fairly blunt filters. Where the metaphor does fit is using a system to create focus. It's important to recognise that OLPC Sugar Labs have very constrained development resources. Therefore, systems that reduce load on developers increases time on development.

After wiping the XO clean and installing 802, Speak v16 seemed to work again with no problems. However, when I closed it and restarted it, I got an error and would not start. I then erased it and reinstalled it. It started up okay with no problems but I get the same result when I close it and restart it.

When it hands the xo an ip addr it also says that it is the dns server (192.168.1.1). I'm guessing the xos can find each other, just not the server. Some wireless routers allow you to add static addresses to the dhcp/dns and some even discover them, but don't know the device name. If yours does, just add 192.168.1.100 and tell the WAP that its name is Schoolserver. If you want to use the XS as dns, I think you will need to use it as dhcp as well. I know the AU-XS folks are working on a simple way to turn this on, but I'm not sure if it is in place yet. In this case you need to turn dhcp off in your WAP. What happens if you go into the networking maintenance section on the xo and tell it that your schoolserver is 192.168.1.100 rather than giving it a name?
