Heh, actually rpm has had %license special file attribute since rpm 2.5.4, 
it just doesn't really do much anything at all. It also doesn't play well 
together with %doc, AND since the ancient copyright -> license tag change, 
%license as file attribute has gotten globbered with side-effect macro 
from the License: tag, so you'll have to use %%license in the %files 
section.

Other than that, making --excludedocs not affect %license files is 
literally a one-liner.

Making %license use in spec saner is somewhat more complicated (due to the 
funny little historical issues listed above). I take it you'd like it to 
behave exactly like %doc, like

%files
%doc README NEWS ChangeLog
%license COPYING
%{_bindir}/*

...which would place COPYING into the default docdir, but with the license 
attribute set. Right?

Re: [Sugar-devel] GSoC project proposal

[Jameson Quinn]

Hi Ishara.

One quick recommendation: you'll probably get more comments if you post your
proposal on the wiki and in email directly, rather than as an included file.
This is especially true when you use semi-proprietary data formats like
microsoft .doc, which many people in the open source community take a dim
view of.

As to your actual proposal, it is interesting in terms of the use cases, but
pretty weak in terms of technical detail. Particularly as you refer to
postgresql, and yet it is not clear where this would be running. Your
diagram seems to indicate that the database exists in copies both on the
teacher's machine and on the school server. Remember, Sugar activities
should try to avoid assuming good connectivity, and should work with very
limited computational resources (processor, disk, and ram). We will consider
proposals relating to the "XS" or school server, which would have slightly
higher resources; but if your idea will ony run on the XS, then how is it
different from Moodle?

Cheers,
Jameson

[Sugar-devel] GSoC idea: Chart/graph-making activity

[Garrison Benson]

My name is Garrison Benson and I'm an undergraduate computer science student
at Hope College in Holland, Michigan, USA. I'm interested in participating
in Google Summer of Code and I'd like some feedback on my idea...

I want to make a Sugar activity that will allow students to create charts
and graphs (e.g. pie charts, line graphs, etc.). I haven't been able to find
such an activity (SocialCalc can create bar graphs, but nothing else). I see
it being useful for formal science experiments, such as the classic "chart
the growth of plants over the course of time" experiment that everybody does
in primary school. It'd also be cool if it allowed students to view the
graph and the data at the same time, so they could modify the data and
immediately see the effect on the graph. (It would help students to gain a
fundamental understanding of the relationship between the graph and the
source data.) It'd also be pretty cool if it could somehow interact with
existing activities such as Measure, Ruler, Poll Builder, etc.

A traditional spreadsheet kind of interface would work (something like MS
Excel or OO.o Calc) but I think a more basic, application-specific interface
may be more accessible.

Anyway, who's got comments or suggestions? Thanks in advance!

I think that's a great idea!  Many people have started projects to create
spreadsheets for Sugar, but none have finished.

Some pointers:
http://lists.laptop.org/pipermail/sugar/2008-February/004225.html
http://lists.laptop.org/pipermail/community-news/2008-February/97.html

Three classes of approaches have been attempted, roughly:

1. Sugarize Gnumeric
2. Socialcalc
3. A python-based spreadsheet using numpy, matplotlib, pylab, etc.

This sounds great!  The biggest win is the large number of developers,
like you, who are familiar with SWF and Flash development.  Being able
to author activities and content in an already known language will
reduce the barrier to entry to new developers.

> could anyone give more info?

Tony and Bryan (CCed), both from the Nepal OLPC deployment have given
this the most thought.  I don't know if SWF will represent the final
answer to this question.  There are several other frameworks under
development.

Any progress you could make this summer, would also apply to other
frameworks if they prove more suitable.

Personally, I am betting that if Sugar Labs can raise the viability of
gnash and SWF in the education space, it won't take long for the gnash
developers to ramp up their development pace.

Gnash's challenge is that  no one _needs_ gnash.  Hard core developers
and freedom advocates can get along just fine without a SWF players.
Casual users can install Flash and it just works.

By incorporating Gnash into sugar we create a class of users
(currently 1 million students and developers) supported by a group of
admins (school IT departments) for whom downloading Flash from a third
party is 'itchy.'  Never bet against the itch:)

[Sugar-devel] Fwd: Summer of Code Proposal: Furthering Speech Recognition in Sugar.

[satya komaragiri]

Hello,

I am a final year student from India. I wish to apply to GSoC this
year by building upon my current work. I had discussed the feasibility
and advantages of having Speech Recognition for an OLPC with the devel
list [1] in September 2008 and have been working on it since then as a
part of the Sarai Fellowship. My progress on that project can be
tracked on its wiki page [2]. I am also working on a dictation
activity under it though it might take some time as I am currently
gathering the speech corpus spoken by children.

This summer, I would like to implement a generic speech library that
could be used by any activity so that children can interact with Sugar
using voice rather than typing. I spoke to Mr. Assim Deodia(cc'ed in
this mail) who developed an activity called 'Listen and Spell' in GSoC
last year and is interested in this idea.

I can showcase one of its potential usages by integrating speech
capabilities to the 'Listen and Spell' activity where the child can
spell out the word verbally. I want to let the children speak out the
spelling rather than type it out. As the alphabet of any language is
limited (26 in the case of English, extension to any language would
just mean getting a few people to read out the alphabet of that
language).

Having a generic library will make system-wide integration easier by
abstracting the interactions with the speech engine via DBUS etc.  All
the activities can use the speech capability as they see fit  (spoken
commands to control the activity is the most straightforward
application that strikes me).

It would be really nice if the community could provide us with some
feedback on this proposal. :)

Are you looking for published data, or researching this yourself? I
see publications on a wide range of languages.

Re: [Sugar-devel] Fwd: Summer of Code Proposal: Furthering Speech Recognition in Sugar.

[Sean DALY]

Greetings Satya,

In the early 1990s I did some tests for a speech recognition system
and I found a shortcut for reliably acquiring and classing words and
even phonemes: asking the subject to click the mouse or the spacebar
to mark the boundary between words. Phonemes were more difficult, but
some subjects did manage to become very proficient in demarcating
boundaries. I seem to remember reading that most of the world's
languages draw from a pool of only 50-60 phonemes. Of course machines
were many times less powerful then compared to today but this little
shortcut simplified realtime processing considerably.

As a former audio engineer I had also explored digitally-controlled
analog audio processing, in particular equalization, as another method
of reducing processing power requirements. However, my results were
inconclusive, due I believe to the slow response time of the equipment
I had available. I recall finally resorting to a first sample to
capture the speech, then conversion to analog for shaping, then
conversion to digital again for analysis. Modern realtime plugin
effects modules for recording platforms such as Pro Tools would
certainly do the job better and in a single step, but the best of
these are very highly priced proprietary closed code (example:
http://www.sonnoxplugins.com).

I did find recognition rates varied very widely with the model of
microphone used. I remember obtaining interesting results from the
proximity effect of a common studio dynamic mic, the Shure SM57; the
"colored" analog sound allowed faster transformations (this is what
led me to shaping sound in the analog domain). Recording very close in
also eliminated ambient room noise. The stumbling block I encountered
there was encouraging subjects to speak right into the mic, which some
found intrusive. I did not test with cheapo soundcard mics as
interfacing these with pro sound equipment for testing was a headache.

It's a fascinating subject

Sean

Try booting with the check button (game key above the power button) held 
down.

If that fixes the problem, the issues is that the OS is not switching 
from "pretty boot" mode to active screen mode.

You can disable pretty-boot by adding these lines to /boot/olpc.fth :

   unfreeze visible

The second line, just after the comment line, is a good place for them.

activity under it though it might take some time as I am currently
gathering the speech corpus spoken by children.

This summer, I would like to implement a generic speech library that
could be used by any activity so that children can interact with Sugar
using voice rather than typing. I spoke to Mr. Assim Deodia(cc'ed in
this mail) who developed an activity called 'Listen and Spell' in GSoC
last year and is interested in this idea.

I can showcase one of its potential usages by integrating speech
capabilities to the 'Listen and Spell' activity where the child can
spell out the word verbally. I want to let the children speak out the
spelling rather than type it out. As the alphabet of any language is
limited (26 in the case of English, extension to any language would
just mean getting a few people to read out the alphabet of that
language).

Having a generic library will make system-wide integration easier by
abstracting the interactions with the speech engine via DBUS etc.  All
the activities can use the speech capability as they see fit  (spoken
commands to control the activity is the most straightforward
application that strikes me).

It would be really nice if the community could provide us with some
feedback on this proposal. :)

i only realized recently that the final unfreeze of the screen
is not done in bootanim, as i expected, but by way of sugar installing
a g_idle callback that sends a message to ohmd to do the unfreeze.  so
if either sugar or ohmd don't start correctly, the screen will stay
frozen.  this doesn't seem optimal to me.  (and it may be that i have
it wrong, and there's another unfreeze mechanism as well.)

(when powerd replaces ohmd, it simply does the unfreeze after 10 seconds
have passed.  also sub-optimal.)

I tried it with no keys presed and it says

Boot Failed

Shut down in 30 secs

Maybe I have a bad image?

Very good. I just got sugar-jhbuild to compile and run for the first
time on Intrepid, and I am trying to see whether I can understand and
help with Debian packaging, with Jonas Smedegaard's help.

Re: [Sugar-devel] SWF Sugar

[Bryan Berry]

Better integrating GNASH w/ Sugar would be great but I argue that time
spent on integrating javascript +html5 w/ Sugar would get a many times
higher rate of return.

A lot of work is being done to develop filesystem API and network API's
for javascript by the Titanium team and the Google Gears folks. Palm is
betting the company on its new WebOS for the Palm Pre where are all
"activities" (ironic they use that name) are done w/ js + html5. 

Conversely, to my knowledge there is not the same momentum w/in the
open-source community to extend gnash or swfdec access to the filesystem
and network resources. I have also talked w/ the Adobe AIR project
manager and he was not interested in extending the proprietary Adobe AIR
to work w/ Sugar. 

In short, there are a lot more open-source projects working on extending
the javascript API on linux than those extending the Flash API.

Here is a detailed project plan for creating a proof-of-concept Sugar
activity w/ Javascript and html5. I personally prefer using titanium
over embedding all of mozilla for the sake of running a relatively small
activity. I like Titanium because it is a collection of existing
open-source projects: webkit, v8 javascript compiler, google gears, plus
a few others. I have yet to run titanium on the XO, so I may actually
find that it is less resource efficient than firefox. I will have to
see.


http://wiki.sugarlabs.org/index.php?title=Development_Team/Project_Ideas#AJAX_Sugar_aka_Karma

copy&paste:

Create a proof-of-concept learning multimedia Sugar activity using
javascript and html5 (for instance, Titanium-made apps). This activity
should have animation, audio, persistent storage of user progress, and
at least basic integration with the Sugar environment. 

JavaScript/Python Communication through the following strategies:
PyXPCom, hulahop, xulrunner or Titanium. see also the mailing list
discussion. The preferred solution should use a minimalist rendering
engine like Webkit and a toolset for local file access like Google
Gears. Such a solution would have much less overhead than embedding all
of mozilla.

  * Ideally, develop a demo activity which could be used as a
template for sugarizing AJAX activities. The GSoC participant
doesn't have to create her own activity but could simply
recreate an existing activity such as one of OLE Nepal's flash
activities. 
  * This demo should have the following features: 
  * Simple interactive animation and audio using html5 tags
like  and 
  * An assessment section that stores results of student's
progress and gives them suggestions on improvement.
Assessment info should be persistent. 
  * Has embedded pdf for lesson plan that can be viewed w/in
the activity
  * Integrates with datastore
  * Navigation and Help elements, ideally reusing widgets
from popular javascript libraries like Jquery,
Prototype, Mootools
  * Some element of collaboration using telepathy (This
could be really hard, depending on the state of
javascript bindings to dbus)

There is some discussion of the prior work on this question at
User:Wade/Web_Activity_Spec.

  * Priority for Sugar: Very High ("never bet against the browser")
  * Difficulty (as a GSoC project): medium/hard Note: integrating w/
the datastore likely won't be too hard but utilizing Sugar's
collaboration features could be very hard
  * Skills needed: Javascript/Python integration (PyXPCom, hulahop),
CSS, knowlege of SQL
  * potential mentors: Wade Brainerd (wadetb at gmail dot com),
Bryan Berry (bryan at olenepal dot org) can serve as project
manager, define requirements and project deliverables
