issues showing Activities for OLPC 8.2.x from a.sl.o.

I want a long-lived URL that will list activities on
activities.sugarlabs.org that work on XO-1's running release 8.2.x,
and I'm confused on several points.

* Should I filter by "Refine Results > Compatible with > 0.82" , or by
choosing Advanced search > Platform: OLPC Software Release 8.2.0
(Build 767), or both?

* Refining results to 0.82 or choosing Sugar version 0.82 reduces the
results returned from 157 to 138, but choosing Platform: OLPC Software
Release 8.2.0 (Build 767) does nothing.  That doesn't make any sense,
implicitly OLPC 8.2.0 *is* Sugar version 0.82 (or, technically,
0.82.1).

* I'm pretty sure the filtering on version is broken.  Etoys, Read,
and Terminal seem to offer the same download regardless of version,
but I believe they have different versions for 8.2.x and later
Sucrose.
Filtering for 0.82 only seems to exclude experimental downloads like
APRS, Bundle, Frotz, etc.

* In Advanced search > Platform, there's no choice for the latest OLPC
version, OLPC 8.2.1 (Build 802). Maybe the Platform option should be
OLPC Software Release 8.2.x , and leave out "Build 767" ?

* In the Advanced search dialog, having "Sugar Platform version" and
"Platform" is confusing.  I think leave "Platform" out of "Sugar
version".

* The feedback in search results if you use Advanced is poor.  It

[server-devel] Setting up the XS

Hi,

So as per Martin's suggestion. I'm making this mail.

I don't have a spare system at my disposal right now,
so I am running XS under a VM.
But I can't figure out how to access the moodle server
outside the VM. (virtual Box)
Other than that moodle is set up.

Thanks,

Vamsi

Get Internet Archive Books Activity source code

Version 2 of Get Internet Archive Books was released this morning.  I
like this one a lot better than my first effort; it should be good
enough to use, not just criticize.  I have put the source code tar.bz
on shell.sugarlabs.org in /upload/honey/GetIABooks, for anyone wanting
to package it up for distributions.

Thanks,

James Simmons

Re: Gitorious problems

Bastien,

For what it's worth, here is my config file for read etexts:

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = gitorious <at> git.sugarlabs.org:readetexts/mainline.git
        fetch = +refs/heads/*:refs/remotes/origin/*

        remote = origin

Hope this helps.

Re: [Cs-dev] Sugar on a Stick - and OLPCsound

I've just noted that the /usr/lib/python2.6/site-packages folder does not include csnd.py. That folder also contains many fewer files that the corresponding one in python2.5.

As a matter of fact, python2.5 seems about a third the size of 2.6. Is all this correct?

Hello, Peter,

Do you know what may be happening here? (Please see error log below.)

I've no idea why the module referenced (csd.py) is not found. Please also compare the log at the very bottom of this mail; this latter log was generated when running Csound*5.08*, also with python2.6.

Thanks for any insights.

Here's the *next* chapter in the saga. Please note that this is not the *Windows* installation saga; it's the *Linux/Sugar* installation saga.

In our last episode, we noted that Csound5.08 was (apparently?) incompatible with python2.6. At least this seemed a plausible explanation from the error log we saw.

So, now Csound5.10 is available on Fedora(11) for download to SoaS.

First, I try update csound; "can't find any csound".

Second, install csound; it tries, but then says, "can't because it interferes with olpcsound" (OK, different name!)

Third, erase olpcsound; good

Fourth, install csound; good

Then I run my Activity; it now crashes with the similar, but not exact, error log below.

I thought perhaps I'd better start from scratch and did (reformat USB drive, etc). Thought probably the new SoaS iso incorporated Csound5.10. But no, I needed to essentially repeat the above steps, and ended with the same crash.

The log: (any new ideas please?)

Because the 5.10 rpm has a python2.6 dependency. But that might

be the case for 5.08 too (I am not sure).

I just noticed that the current OLPC build includes Python 2.5, whereas SoaS includes Python 2.6

Csound 5.08.91 is currently in both. Wouldn't this explain why 5.08.91 doesn't work on SoaS? And why 5.10 should?

The message is strange, but it does not say there is a Python
version mismatch. However, having said that, the 5.08.91
rpm was built with 2.5 (unless what you have there is another
build that somehow uses 2.6).

What the message says is that the library module Python
tried to load does not have one of the API functions. The
reason for this I don't know.

poor man's mmap "sliding window" on Python 2.5.x

Still working on reading and validating Canonical JSON files that are
larger than available memory.

Along the way, found that Python 2.5.x doesn't support an offset to
mmap(), which at first blush makes re-mapping with a sliding window
problematic. Well, almost. If you mmap.close(), re-create the mmap and
start reading at an offset (m[myoffset]), python knows how to DTRT.

So every N number of reads (random or linear), close and re-mmap the
fh. If the reads are short, the memory used by N reads will be roughly

   N * mmap.PAGESIZE

Where pagesize is usually, 4KB. So re-mapping every 4MB for example
keeps the whole process under 6MB while working through a file that is
183MB.

On the XO-1, it's the difference of "churning through it" and slowing
the whole OS to a crawl, and then inching towards a big OOM zap.

cheers,

martin

Release notes:
This version fixes several bugs that were in version 1, allows downloading three different ebook formats
(Color PDF, B/W PDF, and Deja Vu) instead of just Deja Vu, adds a progress bar to show how the downloading of
books is progressing, and allows entries in the search results table to wrap to more than one line if they
have long titles or lists of authors or both.  This Activity has a new icon, and works better on the XO screen
than version 1 did.

Gecko for Win32, pyjamas-desktop, python-hulahop

folks, hi, just wanted to mention a couple of things that i found.

1) you'll be pleased to know that i managed to hack pyjamas-desktop
into submission to use python-hulahop, at europython over the last
couple of days.  i managed to get window event listeners going,
element listeners _and_ XMLHTTPRequest async callbacks - all
python-based.  none of which would be possible without
hulahop.WebView.  so - thank you.

2) i found a page yesterday of a GSoc 2009 student who was proposing
to port hulahop to webkit.  i put on the "talk" page that of course
because pywebkitgtk now has python bindings to the DOM that most of
the work is now done and so his task will be made much easier.  that's
if GSoc 2009 is still going.  or if his proposal was accepted.
anyway, just mentioning it.

3) the next step is of course to have python-hulahop running on win32,
alongside python-xpcom, yippee, won't that be fun.  so, looking around
for xulrunner for win32, i find that the olpc page says "Install
Gecko: TODO" haaaaa :)  so anyway i found this:
http://www.novell.com/coolsolutions/feature/14918.html which may
contain the stuff that's needed. i.e. GRE (gecko runtime environment).
 i mean, after all, firefox compiles for win32 duh so it should be
perfectly possible to get XUL and python-xpcom, right? hmmmm :)

at least three interesting points there from walter

I'd love to hear an expansion of these positions

Also noticed recently that NN reacted against the "netbook" terminology: http://billkerr2.blogspot.com/2009/07/xo-is-not-netbook.html
