I agree, there is no reason we can not setup something like LTSP[1] for a
sugar based desktop lap. NFS mount /home and run the rest from a iso. Can
you say instant dual boot without touching the hard drive.

 -mtune is designed not to break any compatibility.
 So -mtune=atom means that generated code is optimized for atom but *no
 compatibility with other CPUs is broken*.
 So -mtune=atom does not imply that gcc will spit out sse instructions
 because it feels like it. In fact, it will actively avoid generating
 sse instructions in order to maintain compatibility.

 (-march is probably what you are thinking of)

Well sort of, that sets the minimum cpu level to be compiled for, -mfpmath
has hand in the choice that is used for compiling also. I was mistaken,
guess I'll now think of -mtune as the most advanced cpu features that can
be used if present.

Just a thought, I haven't checked yet and have no plans in doing so but
compiling for i686 on a x86_64 machine might use the -mfpmath info, unless
specifically overridden, from the compiling machine where mfpmath default
is to use sse.


  This causes problems for some parts
  of sugar[3] now that java[4] is being used more and the XO-1 lacks sse.

 The WebKit issue happened because it generates its own machine code at
 runtime (not using gcc). It's definitely a bug that it dropped sse
 instructions in there without properly checking if the CPU can do sse,
 but not a common case that you will see throughout the distro.

Good that is not the whole distro it is just WebKit but someone wrote the
code with sse in mind but didn't see the need to fallback if absent.
Perhaps they were working on the assumption that all i686s had sse or
Fedora's lowest cpu supported would have sse available.


 I assume you mean javascript there, and bug #4785 does not look like a
 sse-related issue to me. That issue shows a SIGSEGV whereas if code is
 using sse instructions you would instead expect a SIGILL.

A crash is a crash, and should be fixed. What is the fix needs to be is up
to those who still care.

 I don't think Sugar Labs has lacked a long-term vision. It has been
 since Day One to provide great tools for learning to children while
 being hardware agnostic. That said, our tactics have been slowly
 evolving as the market itself evolves. We launched Sugar Labs in early
 2008 when it was clear to some of us in the community that many
 children would have access to computers other than the OLPC XO. We
 wanted to reach those children, and indeed, many Sugar users run it on
 netbooks such as the Intel Classmate. We've also continued to support
 the XO as well. There are ~3 million XOs in the field, most of which
 are still running Sugar as far as I know. (When I was in Nepal last
 year, I saw Sugar running on machines built in 2007, a testament to
 OLPC's hardware team.

It would be interesting to know what version of sugar/OS those XO-1s are
running.

 I am not sure why Sam thinks we need to discount
 those machines or the kids using them.)

I know this is not a sugar issue directly, more of an OLPC issue but since
Fedora F12 the entire i686 platform's userland is being compiled with
-mtune=atom[1] which would use sse[2]. This causes problems for some parts
of sugar[3] now that java[4] is being used more and the XO-1 lacks sse.
Fixing one package that uses sse might fix one issue but this is really a
distro wide setting and other issues may float to the top in other areas.

Just pointing out issues with XO-1s as I see it.

 Thanks, wasn't aware -mtune=atom was being used upstream.  It explains
 a lot.  First build after Fedora 11 was 11.2.0 (os874) using Fedora
 14.  So if we rebuild everything there may be an improvement?  That's
 probably something that can be set running as a test.


Wouldn't all the rpms used need to be recompiled to ensure mtune is set to
match throughout the distro?

Tall order IMHO, good luck

  Hola Walter,
  Packages and Activities are largely the same as in previous BETA3

  That is Sugar 0.94.1.

  And of course the Sugar Network which is accessible to all:
  http://network.sugarlabs.org/
 
  He have worked hard to keep all of our workflow visible upstream.
  It is always a good time to recognize alsroot's hard work in this area
 as
  the project's upstream developer for Deployment Platform and Sugar
 Network.
 
  I am having trouble finding which activity versions where initially

  OLPC-AU's OS. Maybe you or somebody on the list can provide that info?

I wonder if it's a difference between double clicking the icon or

 With old versions of Sugar, I can't remember how old, deleting the .XO 
 activity bundle from the Journal also uninstalls the Activity. Its a design 
 feature which was abandoned long ago. Are you using an old Sugar version?

 We can load a different Web browser, especially since now since saved

The biggest blocker for browse supporting HTML5 right now is that latest
urlrunner that does support HTML5 from fedora(the last update before
becoming EOL'd) is blocked from installation by olpc-os-builder by
having the rpm present in the olpc rpm repositories.[0] I'm unsure if
there are any changes done to the rpm by olpc or if this is fallout from
building the olpc rpms for both i386 and arm while arm was in
