We use binaries all the time. our web browser uses the gecko rendering engine
from Firefox and Mozilla.
and that all custom content must be Python
Most custom content, when possible, is written in Python. This is a technical
choice, as well as consistency choice. Children that want to contribute need to
learn only 1 language (and an excellent learning language we have in Python).
Most activities and Sugar, the interface of the OLPC, is written in python, for
instance.

Re: status of MANIFEST file

Currently, the MANIFEST is not consulted at all when installing or running, an activity works fine even without it. Only the bundle builder (setup.py) to package your activity uses it. The bundle builder also includes many files implicitly so they do not have to be listed in MANIFEST. The situation might change once bundles are required to be signed, but I don't know those plans. For the activity updater (trac #4951), we will need to include a 'real' manifest with file hashes; this may also be used in the activity signing code. However, I expect the bundle builder to generate this 'contents' file automatically. The short answer, I think, is that the MANIFEST is used to configure bundle-builder; it shouldn't be required in the final .xo (although a related 'contents' files will be automatically generated there). --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Restarting a half-started activity

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.

Re: Reducing pygame cpu-load to 4 %
In this case (animation), the games should go quiet, if there is no user input after a short period (say, 30 seconds).

I'd agree on using apt to get 50% of the work done. And then we could use .deb (or rpm, for what I care) to do the rest of the work. I was told the xo bundle format was invented under the assumption that most developers would have been using Windows, and a very basic zip archive with a manifest inside would have been easier for them to work with. Instead, it turns out that people now ask for specialized packaging tools to automate the process of creating manifests. For some kinds of bundles such as the library, with many small files, writing the manifest manually would have been impossible, so some degree of automation is already starting to appear. If we're going to develop a toolset, then we could have as well ported rpm (or dpkg) to Windows or use the already existing ports in Cygwin. Someone, I think Dennis, wrote an xo - rpm converter. And an xo - deb converter would be equally easy. This is necessary if we want to package popular Sugar activities for traditional Linux distros, where using two different package systems would be crazy. Oh, my... I can't remember why it wasn't crazy for us, too... Well, libraptor is clearly not a system library since it's not installed!

wow, wireless go BOOM!
today i updated my b4 to the latest firmware, then installed ship-2 via usb, then olpc-updated to the latest joyride build that i could find. [the impetus for the updates, today, beyond the RTC bug, was that the wireless on the B4 didn't seem to want to come on. Empty neighborhood screen, etc. There were some libertas error messages in the dmesg output, which were initially somewhat concerning. Now, I wish that I'd written them down. Oops.] a minute ago my ubuntu laptop (an aging dell inspiron 8200, with 802.11b truemobile mini-pci card, running 2.6.22...) started spewing error messages and the card began frequently resetting itself. LOTS of spewage. turning the b4 off seems to have eliminated the issue. huh. :-) possible complicating factors: My local network has a BUNCH of 802.11g devices on it. A d-link pci card, several different belkin and linksys usb dongles, etc. All talking to the one AP. And there are several, several, several APs RF-visible from here - typically 20-30, depending on which window of the house you happen to be closest to. There's also a B2-1 here, running 406.15, with very non-current-ish firmware on it. the AP to which the laptop and the B4 were both connected is a Netgear WGR614v6, running firmware V2.0.13_1.0.13NA. The B2-1 was disconnected and at a point where it would have liked for me to type in a WEP key. The AP is WEP, as there are several devices that don't do WPA and still need to work. This sounds a little bit like the reported WDS/frame/mesh scenarios that I've seen mentioned on a couple of occasions recently... but not exactly. I am happy to do further testing - and endure further possible crashes of my non-XO laptop - to help get this stable again. :-) --elijah ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

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. Thanks all on this list for being so pleasant and responsive to my questions over the past few weeks! -- Kindness is a language which the deaf can hear and the blind can read. -- Mark Twain ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Activity depends on Fedora-packaged binary code
This thing obviously doesn't scale and in the long term we may end up reinventing a full blown package manager with dependency tracking, plus tools like apt for downloading and installing them. It seems to me that the ideal thing would be for Sun to go ahead and get around to releasing certain bits of the OpenSolaris tree under dual GPL/CDDL, so that OLPC can merely adopt something like the Image Packaging System (IPS) being developed for the it-might-be-Solaris-11 Indiana distribution. It is even in Python :-) [and IPS packages (images) have some *distinctly* Activity or bundle-like characteristics... MANIFESTs/(prototype files)... the need for awareness of security contexts... both OLPC and OpenSolaris are definitely of like mind about a few fairly crucial things.] [[a fun project for someone would be to hack up alien to convert RPMs into images... this is all right in line with the overlay filesystems that I've seen mentioned in a couple of different OLPC contexts.]] --elijah ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: wow, wireless go BOOM!
Elijah, Thanks for this information. It would be great if you can start a bug with all this info and then we can follow the suggested steps and results.

Oops.] a minute ago my ubuntu laptop (an aging dell inspiron 8200, with 802.11b truemobile mini-pci card, running 2.6.22...) started spewing error messages and the card began frequently resetting itself. LOTS of spewage. turning the b4 off seems to have eliminated the issue. huh. :-) possible complicating factors: My local network has a BUNCH of 802.11g devices on it. A d-link pci card, several different belkin and linksys usb dongles, etc. All talking to the one AP. And there are several, several, several APs RF-visible from here - typically 20-30, depending on which window of the house you happen to be closest to. There's also a B2-1 here, running 406.15, with very non-current-ish firmware on it. the AP to which the laptop and the B4 were both connected is a Netgear WGR614v6, running firmware V2.0.13_1.0.13NA. The B2-1 was disconnected and at a point where it would have liked for me to type in a WEP key. The AP is WEP, as there are several devices that don't do WPA and still need to work. This sounds a little bit like the reported WDS/frame/mesh scenarios that I've seen mentioned on a couple of occasions recently... but not exactly.

I think we never got the information on the models of APs in use at this conference. But, we deduct by the symptoms that they were linksys wrt54g with lazywds enabled.

Re: Activity depends on Fedora-packaged binary code
This thing obviously doesn't scale and in the long term we may end up reinventing a full blown package manager with dependency tracking, plus tools like apt for downloading and installing them. But seriously, does the XO really need two package managers? What's wrong with Fedora/RPM/yum? Do people really need to spend ergs on supporting Debian? Neither APT/dpkg/deb nor yum/.rpm toolkits have, that I know of, any kind of support in them right now that would let them work safely with something like Bitfrost/Rainbow/security domains. This is, obviously, a pretty important thing for Linux in general, across all distributions, and particularly for projects like OLPC. Some wheel-reinvention may go on, possibly more than once, before dust settles and folks agree on a common solution that is more than just a one-off hack to support OLPC. [Something like Conary, or IPS, or whatever someone finally does the legwork to make extensible into bitfrost/rainbow-land I suppose there could be considered to be an arms race of getting the technology worked out to do the right things with minimal hassle :-)] --e ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
