Thanks, I appreciate the feedback on this question.

I did some testing with License activity a while back, and do like the

forced through all those pages of description to get to the license I 
wanted, I then named the instance 'my choice of CC license for content 
blah', and then when I resumed later to have another look, License put 
me back to the start of the whole process again – I had expected my 
choice of license to have been kept as state so I could resume later and 
check what I had chosen.

Well if you're looking for feedback ;-) the main things I'd like to see are:

1) Add the required license information into the activity.info file! ;-)


*blushes*


2) Store activity state so a kid can resume back to where they were
3) Smaller images, there are almost 4Mb of png files eating into the precious 
XO storage space, I'm sure jpg would be more than good enough.


Interesting point.  At least I could perhaps drop the resolution.

4) A leaner activity, there is a 3.5Mb 'built' directory in the bundle and 
digging down most of the is taken up by built/share/liblicense/licenses, 
could the license data be kept compressed and just unzipped when finally 
displayed, text compresses really well, and python has modules for working 
with compressed files.


Good points all around.  I'm running low on time to work on it, but I will

Allowing an activity to be launched multiple times in parallel

I have a general sugar UI question: My activity, License, a simple comic 
book reader http://wiki.laptop.org/go/License that has a license chooser

Creative Commons branch of Sugar + Journal

2008-02-26 Thread Asheesh Laroia
I've been working behind the scenes on some changes to Sugar and the 
Journal that allow storing and modifying Creative Commons license 
metadata.  It's pretty rudimentary, and it's more of a demo than code that 
should be merged the way it is, but I'd love to have some feedback on it.

http://wiki.laptop.org/go/Creative_Commons#How_to_try_it is some info. 
To summarize here:

* http://dev.laptop.org/ticket/3529 is a ticket with the history of this

* http://dev.laptop.org/git?p=users/paulproteus/journal-activity.git;a=summary 
is the gitweb of my Journal branch

* http://dev.laptop.org/git?p=users/paulproteus/sugar.git;a=summary is the 
gitweb of my Sugar branch

To make this go:

1. 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.

Sugar first:

git remote add asheesh git://dev.laptop.org/users/paulproteus/sugar.git
git fetch asheesh
git merge asheesh/master

Then the Journal:

git remote add asheesh 
git://dev.laptop.org/users/paulproteus/journal-activity.git
git fetch asheesh
git merge asheesh/master

3. Then build, and run!

I'd like feedback (mostly from laptop.org'ers, but anyone else is fine 
too!) about the UI, the implementation, the bugs, the data store 
interactions, and so forth.

You'll find that my additions are technically fairly simple.  The major 
difficulties, I think, will be working out the UI for this, which is 
something that I am not comfortable with, and maybe thinking through the 
right way to make this accessible to other activities (data store usage).

Please, please reply with either I need more instructions getting it 
going or I got it going and have this to say.  I want feedback!

 Hi,

 I would like to get the general feeling about the XO and email. There is
 a Gmail activity but no possibility of composing and viewing emails
 offline, which I think is important.

I think that might be nice also!

 - With Python, an email activity can be accomplished with the
 RFC-compliant email modules (for POP, SMTP, IMAP, MIME) and using sqlite
 for storage. 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. (-:

Once you start thinking of this in terms of interoperability with existing 
mail systems, I think you'll find you have way less work to do.  For 
example:

 - Email threading: there is some Python code at
 http://www.amk.ca/python/code/jwz, which could be adapted

Built-into IMAP, which Dovecot implements.

 - Search using sql queries

 I have a good mental picture of what I want to do - maybe I am not
 communicating it too well, but I am willing to elaborate. 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.

[ANNOUNCE] Beta release of Creative Commons licensing activity

2008-01-14 Thread Asheesh Laroia
I'm happy to announce a beta release of the Creative Commons licensing 
activity for the XO.

This activity is a comic reader that includes simple English text to 
explain the images.  This is based on a comic we published a few weeks 
back that was written with the XO audience in mind: 
http://wiki.creativecommons.org/Sharing_Creative_Works

It also includes a license chooser; right now, the results of that license 
choice aren't used by anything, but we hope to work with XO developers who 
want to integrate CC license choosing into their activities - they can 
perhaps use the license chooser we bundle, and they can perhaps use as a 
default the license chosen by the child at the end of the CC Licensing 
activity.

You can download the .xo at 
http://labs.creativecommons.org/~paulproteus/olpc/License-3.xo .  It even

I've bounced your comments on the comic to Alex Roberts and Rebecca Rojer

I think that's a great idea.

 I bought mine, showed it around my office, convinced one or two others

On Wed, 2 Jan 2008, Bernardo Innocenti wrote:

 I think we should re-enable the empty root password for
 Update.1.

 The reason why is that we have plenty of documentation in
 the wiki and elsewhere suggesting people to login as root or
 to su as root.  There should be at least a transition period
 so the support people don't get flooded with questions on how
 to login as root.

Can 'su' be replaced with a wrapper that runs 'sudo -s'?  That way, only 
the olpc user can run sudo su, but activities can't get root.

We could also have a race through the wiki to replace mentions of 'su' 
with the appropriate sudo call.

 We could also use pam_wheel to let olpc become root with
 no password using the friendlier su in addition to sudo.

 Even better, we could put

  /sbin/mingetty --noclear --autologin root tty1

 in inittab to circumvent the issue altogether.

If the OLPC security team says that's fine, then it does help avoid 
updating the documentation. (-:

Restarting a half-started activity

As I debug how to start my activity with an LD_LIBRARY_PATH (or for other

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?

Activity depends on Fedora-packaged binary code

2007-12-10 Thread Asheesh Laroia
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. (-:

 This is my understanding.  As long as it's just one library, it isn't a 
 big problem.  I have a friend who is packaging 5MB of Mono libraries for 
 an activity written in C#.

That person is still your friend? (-;

 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.

Right.  Let me note here that apt is flexible on packaging formats in the 
backend, as apt4rpm has shown.  There's no need to reinvent it, and I 
think there are some stealth Debian fans sometimes hiding in 1CC

 Static linking is being quickly phased out from all Linux
 distros.  In OS X, static linking against system libraries
 is no longer allowed.

Well, libraptor is clearly not a system library since it's not

First pre-release sample thing of Creative Commons' Licensing activity

2007-12-10 Thread Asheesh Laroia
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!

Bundling Python extensions that depend on C libraries

2007-12-07 Thread Asheesh Laroia
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.

I know this is a sort of strange thing to do, but what's a reasonable way 
to do it?  Thanks, as always!

7. 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. You can always add more lists
later.

9. Commit notifications

[ ] Notification of commits to the main tree should be e-mailed to the list
we chose to create above
[ ] A separate mailing list, projectname-git, should be created for commit
notifications
[X] No commit notifications, please

10. Shell accounts

As a general rule, we don't provide shell accounts to developers unless
there's a demonstrated need. If you have one, please explain here, and
