Install the liblicense RPM at http://downloads.sourceforge.net/cctools/liblicense-0.4-1.i386.rpm (forcing the dependencies, for now; I'll build an updated RPM soon). 2. In your jhbuild (or what have you), pull my changes from my git repository.

There is a Gmail activity but no possibility of composing and viewing emails offline, which I think is important.

So while building upon Tinymail (http://wiki.laptop.org/go/Tinymail) is an idea, it makes sense to just go with Python email modules and sqlite if the next point is to be implemented :-) You suggest using sqlite for storage, and further, as I understand it, writing your own mail storage layer. But on the other hand, you could use an existing top-notch Free Software mail store, like Dovecot. Dovecot comes with full-text indexing for search of email, for example, and header caching to optimize common queries (Tell me all the From, Subject, To, and Date headers). That's my main contribution to this thread - I fear you won't re-use some already great software. The rest of your suggestions could perhaps be implemented as Dovecot plugins to minimize wasted work; for the most part, I agree with them.

I would really like your feedback especially on the fundamental idea of using Python email modules and sqlite in case I am thinking in the wrong direction, although this appears to me to be the best approach IMAP provides SEARCH TEXT, which Dovecot can now (as of 1.1.rc1) store an index for, and therefore return answers in split-second times in many cases. -- Asheesh. -- You're already carrying the sphere! ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Restarting a half-started activity
As I debug how to start my activity with an LD_LIBRARY_PATH (or for other reasons), sometimes it fails to start correctly at all. In those cases, my activity's icon just sits in the ring that shows running activities. When I move the mouse over it, Sugar tells me it is Starting..., but when I look for its process in the 'ps aux' output, the process has already terminated. How can I remove the activity from the Sugar thinks it's starting state so I can reattempt to start the activity without rebooting the laptop? (Thanks all; you've been super helpful so far.

Activity depends on Fedora-packaged binary code
My activity reads RDF files and uses libraptor.so.1 to do that. Fedora does package this in the raptor.i386 RPM. This package is not installed on the Build 650 I'm using. I also see no way to specify RPM dependencies in a .xo nor a way that deployed XOs could be guaranteed to be able to get dependencies from the RPM side of the world upon receiving a new .xo. I suppose I'll have to include a libraptor.so.1 in my own .xo's lib/ directory. Is the normal(ish) way to do this by just unpacking the RPM and yoinking the Fedora-compiled .so and jamming that file into my .xo? (I could just statically compile the libraptor dependencies into my shipped binary code also, I suppose, but I'd rather not consider that option.) I'm open to other ways of thinking about this if they would prove more productive.

First pre-release sample thing of Creative Commons' Licensing activity
I'm deeply fearful^W^Wproud to announce the first version of the CC licensing activity. Let me give you all some background, and then scar you all with a link. One of the core activities of the Creative Commons organization is getting software (apps and platforms) to support metadata showing and searching when viewing files that contain Creative Commons licenses as well as letting users CC-license their files. We have been chatting with OLPC about some sort of integration for some time; indeed, one of our summer interns was tasked with working on it. http://wiki.laptop.org/go/Creative_Commons has the old brainstorming. What we've converged on is an activity with a comic, to be translated widely, that an XO activity will show, as well as letting the kids play with a license chooser. That license chooser UI will probably show up again in the control panel; probably the license chosen there will be the default if they choose to CC license other work they create. That summer intern wrote a patch some time ago to let CC licenses be chosen in the journal, which is in the old ticket https://dev.laptop.org/ticket/3529 . ENOUGH ALREADY! WHAT IS THIS ACTIVITY? --- It's: * A first-run disclaimer, to be considered by our legal staff who have conerns like the possibility of under-18 people doing licensing, * A simple back-forward viewer of a comic, with text at the bottom, and * A license chooser widget available in the Navigation menu. * available at http://labs.creativecommons.org/~paulproteus/olpc/License_1.xo * appallingly large, which I work on soon * trackable in gitweb: http://dev.laptop.org/git?p=projects/cclicensing;a=summary KNOWN BUGS? --- Of course. The license chooser's first time loading is very slow, and it writes to ~/.license/ , which is bad news for the impending security review of activities (I'll fix both soonish). YOUR HELP? -- Two questions: 1. As you click back and forward, the screen is sort of jerky, and the text widget seems to appear on the screen twice for a moment. Is there a way to make this smoother? 2. How do I make the Navigation menu selected by default on application startup? It seems the Web activity does this, but I can't quite figure out how (indeed, I used it as a reference for making this activity). YOUR TAKE? -- Please take a look at this thing and let me know what you all think. Within the week, we're going to be putting the comics+text up on the web in a convenient format for reading and commenting; consider this a preview of that. -- Asheesh. P.S. Thanks Alex, Jon, and Rebecca for making the comic! P.P.S. The all-caps are section titles, not me shouting! P.P.P.S.

Bundling Python extensions that depend on C libraries
I'd like to bundle a Python C extension and use it from my activity. This requires Python to dlopen() a shared library whose path can change depending on where the activity is installed, but also whose path is different than on my desktop where I built the .xo. Initially I tried to set os['LD_LIBRARY_PATH'] from within Python, but I learned this would not affect the running application http://hathawaymix.org/Weblog/2004-12-30. In the Log Viewer, I read: type 'exceptions.ImportError': liblicense.so.0: cannot open shared object file: No such file or directory I tried changing my activity.info to read, in part (all on one line): exec = LD_LIBRARY_PATH=/home/olpc/Activities/License.activity/built/lib sugar-activity ccactivity.LicensingActivity -s but the error persisted.

Preferred development model [X] Central tree. Every developer can push his changes directly to the project's git tree. This is the standard model that will be familiar to CVS and Subversion users, and that tends to work well for most projects. [ ] Maintainer-owned tree. Every developer creates his own git tree, or multiple git trees. He periodically asks the maintainer to look at one or more of these trees, and merge changes into the maintainer-owned, main tree. This is the model used by the Linux kernel, and is well-suited to projects wishing to maintain a tighter control on code entering the main tree. If you choose the maintainer-owned tree model, but wish to set up some shared trees where all of your project's committers can commit directly, as might be the case with a discussion tree, or a tree for an individual feature, you may send us such a request by e-mail, and we will set up the tree for you. 8. Set up a project mailing list: [ ] Yes, named after our project name [ ] Yes, named __ [X] No When your project is just getting off the ground, we suggest you eschew a separate mailing list and instead keep discussion about your project on the main OLPC development list. This will give you more input and potentially attract more developers to your project; when the volume of messages related to your project reaches some critical mass, we can trivially create a separate mailing list for you. If you need multiple lists, let us know. We discourage having many mailing lists for smaller projects, as this tends to stunt the growth of your project community.
