To: Dextrose Mailing List , OLPC Devel
, Sugar Devel



Hi,

This mail is a notification of the international release for
Dextrose-2 non-gnome builds for the XO-1 and XO-1.5 laptops.

Among new additions to this release is the automatic crash reporting
and manual feedback feature. Users can click the 'submit a report'
icon in the frame and submit feedback reports which will be visible to
the dextrose team. Feedback submits will not include any personal
information such as user's nick and laptop serial number. This release
also includes nearly complete Spanish translations for many new
components added recently to the build. On the server side, we have
setup yum testing repositories, and a feedback daemon service to
accept all submitted reports and the capability to parse these
feedback submits and send it to a mailing list.

Thanks to extensive testing, many interesting bugs were reported and
fixed in this development cycle. The current list of bugs and
enhancement requests (including closed tickets) is here [1]. To enable
us to effectively track and fix bug reports, please add 'dx2' to the
keywords list and '[dx2]' to the title when opening a ticket [2].

In an effort to make it easier for users to know about and use the new
enhancements, a few single page documents have been created
[3][4][5][6]. We hope to keep adding such documents in the future, the
links for which will be available in the wiki [7].

The non-gnome builds can be downloaded from here [8][9]. I can
generate the gnome versions if requested (and really needed).

   Project Objectives: (excerpt)
   The new computer curriculum aims to give the children basic computing
   literacy, including the skills they will need in high school (for
   example, touch typing, word processing, email and Internet research
   techniques) to place them on a more level playing field with their more
   privileged classmates and to ensure that they have a solid foundation to
   build on in their high school classes. OLPC’s XO laptops are especially
   good for this purpose due to their portability, ease of charging, and
   simple interface. More specifically, since our summer program ends with
   a final exam, we aim to have at least 90 percent of our students pass
   the exam on the computer curriculum. We are starting literally at the
   beginning with these kids - most have never used a mouse - so the
   outcomes will be especially visible not only in hard outcomes like their
   test scores, but also in soft outcomes like quality of school projects,
   and general readiness for school.

   Project Objectives:
   Friends Academy is seeking to establish a long-term partnership with
   Ecole Mixte Choubert Alexis in Gonaives, Haiti, an accredited school
   that was devastated in the 2010 earthquake. The school would be one of
   several schools in our network. Our objective is to collaborate with
   students around the world on the kinds of projects that require 
teamwork,

   complex communication, creativity, technical competence, and other 21st
   century skills. These projects can take many forms. Imagine students at
   one school creating storyboards, students at another school designing
   the artwork, students at a third school composing the music, a forth
   class producing the final video. This kind of project and those like it
   differ from the usual correspondences and pen pal exchanges that 
teachers

   initiate with their international partners. We will also have these
   initial exchanges, but expect more out of these partnerships in the
   long-term. The projects we propose provide students with genuine
   learning experiences. They also build friendships, cement relationships,
   and bridge cultures. They require intense and sustained collaboration.
   Apps like[ http://translate.google.com/ ] translate.google.com can help
   with the language barrier. Email, wikis, and blogs allow us to network,
   share and collaborate. These projects allow children to share their
   stories, experiences, culture, values, ideas, and dreams. We believe
   projects like these can be powerf

Well, I tried it for Etoys. On a ca. 1968 terminal it's way to slow. But the XO 
is way more powerful (in particular the 1.5) so this is worth pursuing, IMHO:

Yes, power consumption has been one of our greatest concerns as the pixel to
semicolon bump causes some serious strain.

The XO tablet's gpu will probably handle this going forward.

Muchas Gracias Rodolfo

Lo he instalado en un XS acá en Nicaragua, por lo general nosotros usamos
openDNS, pero en esta escuela se me hizo imposible, ya que ellos cuentan con
un modem 3G.

Al parecer el filtro está funcionando...

Possible XO Graphics Optimization Technique

2011-04-01 Thread Samuel Greenfeld 
Hello all:

As many of you are aware, work is being done to improve the graphics
performance of various XO laptop platforms.

So in an attempt to improve things further, I looked into optimizing the
data Sugar sends to the video subsystem itself.

I think I have made some improvements, and put up some samples of my Sugar
interface work at http://www.greenfeld.org/1April2011/ .  Feedback is
welcome.

But while I have drastically reduced the amount of bandwidth required to
display the Sugar interface, I fear I have significantly increased the
amount of power required for optimal rendering.

I've seen the 0x41/0x3432 before on a Kingston card, and this looks
like an improper OEM ID because it's not actually letters in ASCII.
Kingston was not able to confim this card to be either authentic
or fake, but measurements have shown that it has the same flawed
GC algorithm as the others (only one allocation unit open at a time,
no random write optimizations).

I've seen the 0x1d/0x4144 ID on cards with very different characteristics,
a very good one branded "Microcenter" and a rather bad one branded
"Extrememory Performance Class 6". Note that 0x4144 is "AD" in ASCII,
so that is likely to actually stand for A-DATA, who would produce
the controllers and sell them to the other OEMs.

The Transcend controller is new to me, the few other transcend ones
I've seen were using Samsung (0x1b/0x534D, "SM"). 0x5356 is "SV", which
I have never seen before, it could plausibly stand for "Sunvision Co.",
who are listed as a SD licensee but not a brand name.

If you want to do more tests, please get the flashbench source code from
"git clone git://git.linaro.org/people/arnd/flashbench.git" and send your
results (one mail per card) to flashbench-resu...@lists.linaro.org.

The data should include:
* The contents of all sysfs files
* The exact size of the card in kb
* The output of "flashbench -a --blocksize=1024", which is needed to guess
  the erase block size. The README file tells you how to interpret the
  results, ask me if you're not sure.
* When you have the erase block size, the results of
  "flashbench --open-au --open-au-nr=${NUMBER} --erasesize=${ERASESIZE}"
  for the correct erase block size and a varying number of erase blocks.
  Try different numbers until you find the highest one that is fast
  and the lowest one that is slow (one more than the first).
* The the --open-au test with and without "--random". The Kingston card
  will always be slow with --random, so no need for that. For cards that
  are fast with --random, always use that, in orer to get more accurate
  numbers.
* Use the '--findfat --random' test with the correct erase block size to
  determine if the card has any areas optimized for random access that
  can be used to store the FAT. On the Kingston card, this will be the
  second 4 MB erase block.
