Re: Yay!, Bee, See (ABC) software
Such a system sounds great to me! If it's similar to the widget formats supported by the Mac OS X's Dashboard, Konfabulator, and/or Opera that would be even better, since it would tie into an existing library of useful software. Basically, those use ZIP files with various custom layouts, content-types and HTML. I have constructed a widget package which worked in both Opera and Mac OS X's Dashboard, and it was not too difficult (only the Content-Type varied, which I handled using symbolic link on my Apache server.) -Ben On Sun, Jan 4, 2009 at 7:28 PM, Wade Brainerd wad...@gmail.com wrote: BTW, this activity is a perfect example of what I was talking about with my 'web-activity' and sugar.activity.activity.WebActivity class proposals.

In a same spirit, a friend of mine created jLearn: http://domosays.net/jlearn/. JLearn (JQuery learn) is a simple program that allows you to learn anything (if a quizz has been written of course!). From japanese alphabet to maths, passing by world capitals, anything can be learnt. JLearn interface is pretty simple: one box showing you the question, and one box to enter the answer. If you don't know the answer, just press the [space key] and it will be shown. Quizzes are submitted by the community, you can find some here or even write your own!

Re: Yay!, Bee, See (ABC) software
Ben -- When you're zipping up the directory, if you add a metadata file in this subpath: library/library.info and give the resulting zip file the extension .xol, you'll have an XO library bundle. Here is a sample info file, with all required fields : http://wiki.laptop.org/go/Image:Yay-bee-see-library.info Note that the 'name' field in the info file should match the name of the root directory. Our standard is to increment the version # in the metadata every time you make a change; that allows tools like Sugar's software updater know when there are newer versions of packages available to install.

Re: Yay!, Bee, See (ABC) software
Thanks! A few questions, though: 1. Is there any reason I shouldn't start with your version 2 .xol as my baseline? I'd like to update it to use the new lower-resolution, lower-quality images (which still look just fine on the XO-1 even in greyscale high-resolution mode zoomed out to the 1px = 1px scale.) 2. Is there some way to install the .xol more user-friendly than just unzipping it into the ~/Library directory? 3. I notice that in the description on the wiki for the bundle you wrote fdl text, pd, cc-by and cc-sa images. Some of the images are cc-by-sa and fdl, too. Also, the HTML text is actually pd (or at least it was in the version I released — of course you are welcome to license copyrighted derivative versions however you like.) 4. And finally, is there some reason the OLPC wiki does not work right when viewed from an XO-1? I had to go through URL-hacking contortions to open that page in Browse (it just said the page was empty otherwise.)

Yes, that's a fine baseline.

If you download an xol file onto your xo from a webserver that has mimetypes set properly (such as w.l.o) it should automatically install itself into your Library/ directory.
