I talked with one of the 802.11 experts I know. He's quite sure that there should be no problem on Atheros hardware at least. He has no problem transmitting arbitrary packets at arbitrary times and no problem receiving packets either. The only limit is that you get just one channel at a time. I'll check with a couple of the other experts I know. The TSF stuff looks like an optimization that you don't really need, except perhaps when sending to a receiver that stops listening at certain times. Lame hardware misses out, no surprise. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Because I need it to conduct test and I want to be sure to save another instance of the project, under another name. Btw, I can confirm you renaming the project in Etoys toolbar then saving does not produce another instance everytime. The modus operendi of the journal does not looks intuitive to me, but well it does not count really as I am not the typical target audiance.

Re: Developing Applications on Sugar
I think the easiest way to get started is to modify an existing activity. The source to all of Sugar and the Sugar activities is available in our git tree: git.sugarlabs.org regards. -walter On Thu, Oct 29, 2009 at 4:01 PM, Emeka wrote: > Hello All, > > I have gone through Python langauge tutorials and books in order to be able > to write applications for Sugar.

Developing Applications on Sugar
Hello All, I have gone through Python langauge tutorials and books in order to be able to write applications for Sugar. Now, I need tutorials that based on Python that run on Sugar. I would also want to have poniters and links to the source codes of applications written for Sugar environment. Any other help that might be useful to me please don't hesitate to send across. I hope this post is in the right group, if not please let me know where to post it. Regards, Janus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

This defines the basis of the timing synchronization function (TSF) which is a core part of 802.11. Without synchronized clocks, nodes cannot communicate.

Simply click the Keep button to create a new entry in the Journal. Simply edit the name in the Etoys toolbar to rename. Or rename in the Journal. The hidden save menu options let you save to a file or upload to the Squeakland website. They do not save to the Journal.
