 Hi,

 the Sucrose package of Pippy is version 25 - when I last released it
 back in August. Since then there has been some development going into
 Pippy (now version 30)
 http://dev.laptop.org/git?p=projects/pippy-activity;a=shortlog

 But none of the maintainers did follow the Sucrose release cycle, even
 though I sent a reminder
 http://lists.laptop.org/pipermail/sugar/2008-November/010021.html

 Any, specific reason for that? Pippy has not been moved to
 git.sugarlabs.org, as well.

 please indicate clearly:
 * if you still want to be part of Sucrose (including following the
 release cycle)
 * any new maintainer that is willing to do this task if you does not want to
 * any issues/reasons you have to do so

 Best,
 Simon

 To follow up on this, I mainly want to find a maintainer for Pippy for
 Sucrose. If there is no one willing to do that we drop it, which is ok -
 one can still download the xo etc, I just want a clearer situation.

 Hi,

Hi Brian,

this is awesome!

 I will maintain Pippy for Sucrose, though I may need a bit of hand holding.

Hand holding we provide as a default service, you are always welcome to 
ask if things are unclear.

 Please let me know if what I did seems correct (esp. step 2):
 
 1. l got the most recent version of Pippy from git
 git-clone git://dev.laptop.org/projects/pippy-activity
 cd pippy-activity
 
 2. ./setup.py gave a bunch of invalid entry in MANIFEST errors about
 different locales, so I ran:
 ./setup.py fix_manifest

Did you use 0.82 when doing ./setup.py dist_source?

The dist_source command uses git-ls-files to get the files it will 
package into the tarball. So only files that are in git will get into 
the source tarball.

The dist_xo command uses the manifest as a source to determine the files 
present. Only files in the manifest will be present in the bundle.

There was an error in the activitybundle code in 0.82 that tried to read 
the manifest as well in the source case - which is not needed. Hence, 
the warnings you saw about the incorrect manifest should not be seen 
when packaging the sources. This is fixed in recent code.

Hope to have explained a bit the possible story around this error.

 3. ./setup.py dist_source
 
 4. I asked a crank sysadmin to add me to the Sugar group,
 And I moved Pippy-30.tar.bz2 to:
 http://dev.laptop.org/pub/sugar/sources/Pippy/Pippy-30.tar.bz2 (805K)

The exact release process for the Sucrose release is described here: 
http://sugarlabs.org/go/DevelopmentTeam/Release#Fructose

 I will move pippy over to git.sugarlabs.org as well.

Instructions for that can be found at: 
http://sugarlabs.org/go/DevelopmentTeam/Git#Import_a_module_from_dev.laptop.org

 Thanks,
 Brian

Thank you,
Simon

 Wade, do you have maybe someone in mind?

Turning off the mesh to save battery power

hey guys, here in Nepal we are deciding whether or not to turn off the
mesh on our custom XO build in order to save power. We will leave on
regular wifi. 

Any ideas on how much power we will actually save? An extra hour of

 Hi folks,

 Kim Quirk kindly stopped by #olpc-meeting this evening and precipitated an
 impromptu discussion between herself, me, cjb, edmcnierney, mchua, and
 garycmartin on how to push 8.2.1 a few inches closer to release.

 The main conclusion that we reached after we updated

   http://dev.laptop.org/report/38

 was that staging-9 [1] needs some testing! In particular, it's got 
 long-awaited
 new wireless firmware and wifi kernel drivers which means that we need to know
 whether it still associates with your crazy encrypted access points. :)

 At any rate, the bottom line is that YOU can personally help 100k kids in
 Uruguay get access to 8.2.* faster by helping to test this build. (Guadalupe
 and Emiliano in Uruguay have already helped to test fixes for some of the
 issues they found in 8.2.0 but more (your!) testing help is still needed!)
 So, on that note, thanks very much in advance for any help that you can 
 provide.

 Voluntarily yours,

 Michael

 P.S. - Bryan -- would you please update FiT with instructions for staging-9
 wifi-testing?

 P.P.S. - I'd like to host a test party at 1cc sometime in the next two weeks 
 to
 try to do some large-scale collaboration and wifi testing such as was 
 requested
 by dsd [2] in preparation for his trip to Paraguay tomorrow [3]. Would
 interested people who might be in Boston in the next two weeks please mail me
 to let me know good days and times for them to come help test?

 P.P.P.S. - The major coding work left before we can wrap up 8.2.1 is currently
 resting on Mitch Bradley's capable shoulders [4]. I'm looking forward to
 receiving a new OFW snapshot from him for testing in the not-too-distant
 future.

You've got a point about the keyboard, in my haste to rant I totally

support chords.  That said, I was reacting to the idea that Multi-Pointer X
was the way to handle the screen from a software standpoint.  Instead, if

[Server-devel] Upgrade to 0.5.1

2009-01-27 Thread Reuben K. Caron
There seems to be a differing set of instructions on how to upgrade:

from the wiki:
http://wiki.laptop.org/go/XS_Installing_Software#Upgrading_from_XS_0.4_or_earlier

If you are upgrading from XS 0.4 or earlier, the process is similar to
a new installation, with some minor changes. In the menu shown right
after booting, you should choose the (preselected) 'Install with
kickstart' option, press the Tab key, and add 'upgradeany' to the boot
configuration line. After adding that line, press enter twice.
With this extra option, Anaconda will recognise the old installation and
will offer to upgrade.

the second from server-devel:

http://lists.laptop.org/pipermail/server-devel/2008-November/002493.html

Just to make this clear, for the upgrade to work you need to select one
of the top two options, hit tab and then append upgradeany. The
default selection has the ks.cfg file which prevent the upgrade choice
from appearing as an option in anaconda. (thinks it's the partitioning
info being present)

Passing upgradeany to the kickstart option does not work. Passing
upgradeany to the top two options does work.

Two questions:

1. Which should be used.
2. If you pass upgradeany to one of the top two options that does not
use the kickstart, do you lose any functionalality?

Thanks,
Reuben

Re: Problem running Sugar on openSUSE 11.0

2009-01-27 Thread James Simmons
Jigish,

I am convinced that my installation of openSUSE 11.1 is messed up and my 
best option is to do a fresh install rather than an upgrade.  David 
Fanning had asked me to do a ./sugar-jhbuild depscheck and the only way 
I could run that was to do a git-clone of sugar-jhbuild first.  When I 
tried to do that I got a message saying that git-clone was not found, 
yet YAST and rpm -V both said that git-core (which YAST showed as 
containing that command) was installed.  The file was definitely missing 
though.  I'm guessing that something similar is happening with 
python-telepathy.  I also find that neither of the DVD burning apps that 
come with the distro can recognize my DVD burner, but I have no trouble 
mounting DVDs on it.  11.0 also had some odd problems that I thought 
upgrading to 11.1 had fixed, but apparently some problems remain.

Tonight I'll do the clean install and run your zypper commands again and 
I'll let you know how it went.  Thanks,

James Simmons

Re: Problem running Sugar on openSUSE 11.0

Tomeu,

As I have described in a previous email, I think my openSUSE 11.1 
upgrade is messed up.  Several files seem to be missing even though YAST 
and rpm -V show the packages being installed.  I plan to do a fresh 
install rather than an upgrade to see if that helps.

AMD to stop working on Geodes

AMD sees no Geode chip replacement in sight
AMD on Monday said it has no replacement for the aging Geode low-power
chips that are used in netbooks and set-top boxes.
http://www.pcworld.idg.com.au/article/274414/amd_sees_no_geode_chip_replacement_sight

Looks like AMD's going to be pulling out of the low-power computing
space because of the economic crunch.

This is completely wrong and low-power + efficiency is exactly where
all computing should go. multicore GHz monsters should be sold to
people who really need them and not to joe average who just needs to
surf and do ms office work.

sorry guys, lack sleep, thanks for all the pointers on multitouch 
audio feedback interface - I saw really amazing stuff and am tickled
pink that the precise methods I just outlined are already being worked
on :)

will reply on all these when I get back. This latest piece of news has
been an extremely frustrating development for me and goes completely
against the grain of ubiquitous sustainable computing for everyone +
bridging the digital divide. wrong wrong wrong wrong wrong

see you guys later.

Any tips as to what to do with these 2 on an XO? The only thing I've  
done with .img and .crc before is copy-nand from firmware – is it  
possible to run them from a usb stick without wiping nand or effecting  
the existing nand install (so we can encourage safe(er) testing of new

Neither do Celerons ULV 900 and the current Intel Atom, just see how they
are doing. Call them the Wii of personal computers, if you may.
One of the problems with the Geode LX is that it doesn't run youtube quite
right.
As sales of the OLPC G1G1 came down to 7% of last year, it seems people
didn't like to pay more for a netbook that doesn't do youtube how a $199
EEE does. That 93% less Geodes sold sure must help AMD to not look at the
Geode the same way. A Geode shrunk to 45nm sure would help the XO, heck,
even a 65nm one would.
Perhaps time for a Get 4 Give 1 program? Where each XO sold to the public,
1/4 of it's value is for a donated XO. That could help bring mass production
closer to the desired numbers, mass public availability sure has helped that
darn Classmate.
Just my 2 cents.

Re: AMD to stop working on Geodes

2009-01-27 Thread Carlos Nazareno
it's the low power part that's very important here. it's the XO's
incredibly low power consumption that really sets it apart from any
other currently in production computer (excluding smartphones and
pdas).

I'm not really familiar with the new processors from Intel
(silverthorne, diamondville) and Via's, but can they run at as low
power consumption as the Geode and provide the same (and if not
better) MHz bang for the consumption?

Do ARM processors do these things better than anything else on the
market right now? but then you lose the X86 compatibility and this
probably breaks things for cross-platform upstream contributions for
any deved/researched write-once-run-many apps/projects. (correct me if
I'm wrong, am just speculating because I'm not a CE and as well-versed
with computer architecture)

I've always loved AMD's cool and quiet technology and am pretty much
cursing the unrelenting power draw of my core2-quad desktop coz my UPS
battery life has gone down the drain and electric bill has spiked so
high since I replaced my lowly Sempron.

(I do have the need for speed for rendering)

As for games, can we just classify the XO in the same class as
current-gen smartphones horsepower wise and not market it as anything
other than that? That's pretty much how we're running the Flash Dev
for the XO project because that's exactly how the XO performs (and
it's a hell of a lot better than any smartphone in the market for
heavier mobile computing and education!)

Of course! But, I was quite disapointed when I knew that the 0.9W they
announce for the Geode LX is only the idle power, on typical usage it's more
like:
LX 8...@0.9 W: clock speed: 500 MHz, with power consumption: 1.8 watts. (*TDP
3.6 W*)
Borrowed this line from wikipedia. Now take a look at this one:
Atom Z500, 800 MHz, 512 KiB, 0.80 - 1.1V, *0.65 W TDP, 160 mW* *idle* - $20
As much as I don't really like Intel for the Classmate, this is miles ahead
of the Geode LX. And it's not what I'd call expensive, although I don't have
an ideia of how much the Geode in the XO costs.

 Some laptop manufacturers are designing hybrid laptops with a regular x86

must not be that bad. AFAIK, ARM and Canonical will be doing a push for ARM
Linux in the coming months.

Pretty much all of Intel's power management sucks, even in laptops. Mostly
they don't allow the CPU to clock too low, for whatever reason, while AMD
can clock down to 800-1GHz almost all CPUs.
Also, do you know one thing that Celeron Ms lack is power management?
Unbelievable, given their target market.

The cost of developing and supporting a processor family is staggering.

AMD bought the Geode business from another company.  Often, when a company buys 
a business unit, that unit withers on the vine.  The new kids on the block 
have a difficult time establishing a strong place within the established 
pecking order, so in the competition for resources, the new group often comes 
up short.  When there is an economic downturn, the new group is often the first 
to go.

AMD barely has the resources to maintain a competitive stance in the part of 
the market that has traditionally been their core, especially now that the 
economy is bad.

I'm sure that AMD would be very happy if they had enough money to go after the 
low power market, but they just don't.

Every other (useful) protocol I can see in my /etc/services breaks if

We can muck with HTTP with a transparent proxy that allows us to serve

Sugar has been tested on both x86 and ARM [1].  I expect it would run
perfectly on MIPS, PPC, SPARC, Itanium, Alpha...  Linux runs on just about
every major architecture, and I expect the same of just about any
Linux-based system.

I'm not too worried about upstream support.  Our Activities are mostly
written in Python or portable C, and the underlying operating system is
typically based on Fedora, Debian[2], Gentoo[3]... which already support
all of the above architectures.

It's true that you lose the ability to run arbitrary binaries from other
platforms, but this is only important if you care about closed-source
code.  Most important open source programs are easily recompiled for any
architecture.

Re: Turning off the mesh to save battery power

2009-01-27 Thread John Gilmore
 hey guys, here in Nepal we are deciding whether or not to turn off the
 mesh on our custom XO build in order to save power. We will leave on
 regular wifi. 
 
 Any ideas on how much power we will actually save? An extra hour of
 battery life would be worth it

(1) Try it and see, that's probably the easiest way.  Every laptop has
an instrument in the battery that you can measure its power draw with.
See:

  http://wiki.laptop.org/go/XO_power_draw

When I measured it on 2008-09-12, I got about 0.2w difference between 
a WiFi access point and mesh.  It probably matters how busy your mesh
is, since transmitting uses more power than just sitting there waiting
to receive.

(2) The big win in 8.2.0 from turning mesh off is that the entire WiFi
chip can be powered down when the laptop is closed and suspends.  This
stretches the suspend time from about 8 hours to at least 48 hours,
meaning the kids can just close the lid rather than power-off.  Then
the laptop will be instantly available whenever they open it (e.g. at
home).  If the mesh is still on, the WiFi chip needs power to do its
packet-forwarding job.

(3) If you want an extra hour of battery life, work on the screen
dimming algorithm, or teach kids to turn down their brightness to
increase battery life.  Summary from my results: Normal power
consumption of about 6 watts. By dimming the screen, you can save up
to a watt. By turning the screen all the way off, you can save another
0.5 watt (total 1.5 watts for screen). By turning the WiFi chip off,
you can save up to a watt.

AMD is NOT halting production of the Geode. They are not leaving the

will be kept AS IS. That's a very different statement. They're saying
that it is a mature product (a rare thing in IT).

Currently, the Geode is good enough for many applications and would be
a step up for others. The embedded world tends away from the shiny
object model of upgrades. If it worked last year, it works this year,
and it'll work next year. Changes in the product are considered
undesirable.

AMD's statement doesn't even mean there won't be a die shrink or even
a faster Geode in the future, just that they won't be updating it's
architecture.

It's not a bad decision either. There is a significant niche for the
Geode between the Atom (too hot, too power hungry) and things like the
Dragon Ball and mips (not enough power).

Geode isn't in trouble until Intel comes out with an x86 that doesn't
need a heatsink (or at least doesn't need a fan).

end quote

I've seen the Geode in action in Soekris boards
(http://www.soekris.com/) when I was doing fun Wi-Fi stuff, and used
to wonder what it would be like if we had a Geode machine running a
laptop...well that wish came true with the XO :-)

I'll also point out (peripherally) to a comment made by Jeff Bezos in
a BusinessWeek article
(http://www.businessweek.com/magazine/content/08_17/b4081064880218.htm),
where he says that frugality leads to innovation (necessity being the
mother of invention, etc.) and I think the frugality of XO's design
has definitely lead to many innovations. I for one would *not* have
thought that I would be using a 433MHz x86 laptop with 256MB RAM as my
favorite machine :-)

Hats off to the Geode!

Marvell has bought XScale from Intel. That may be the principal
alternative. The Encore Mobilis being bought by Brazil for its schools
uses an XScale processor and MontaVista Linux, so Sugar Labs should be
working on an XScale port of Sugar soon.

 I've seen the Geode in action in Soekris boards
 (http://www.soekris.com/) when I was doing fun Wi-Fi stuff, and used
 to wonder what it would be like if we had a Geode machine running a
 laptop...well that wish came true with the XO :-)

 I'll also point out (peripherally) to a comment made by Jeff Bezos in
 a BusinessWeek article
 (http://www.businessweek.com/magazine/content/08_17/b4081064880218.htm),
 where he says that frugality leads to innovation (necessity being the
 mother of invention, etc.) and I think the frugality of XO's design
 has definitely lead to many innovations. I for one would *not* have
 thought that I would be using a 433MHz x86 laptop with 256MB RAM as my
 favorite machine :-)

Alan Kay loves to ask how Doug Engelbart and his team managed to
shoehorn all of the Online System (NLS) in The Mother of All Demos
into 192K in 1968.This included realtime videoconferencing and
instantaneous, seamless crash recovery. People come up with all sorts
of technical theories, but Alan's answer is, Because they wanted to
badly enough.

 Hats off to the Geode!

 cheers,
 Sameer

 Do ARM processors do these things better than anything else on the
 market right now? but then you lose the X86 compatibility and this

 I'm wrong, am just speculating because I'm not a CE and as well-versed
 with computer architecture)

 Sugar has been tested on both x86 and ARM [1].

How about the XScale version of the ARM architecture? Is anybody
working on that? We need it for the Encore Mobilis port, on Montavista
Linux.

It would be hilarious to me if the XO-2 had an XScale processor, and
Microsoft suddenly had to port Windows XP to it in order to stay in th
game. :-Þ

 I expect it would run
 perfectly on MIPS, PPC, SPARC, Itanium, Alpha...  Linux runs on just about
 every major architecture, and I expect the same of just about any
 Linux-based system.

None of the Geode-specific power management code would work, of
course, but that's kernel-level stuff. It doesn't go into the .xo
bundles or the distro-specific packages.

 I'm not too worried about upstream support.  Our Activities are mostly
 written in Python or portable C, and the underlying operating system is
 typically based on Fedora, Debian[2], Gentoo[3]... which already support
 all of the above architectures.

 It's true that you lose the ability to run arbitrary binaries from other
 platforms, but this is only important if you care about closed-source
 code.

That means, for us, Flash and drivers. There are Open Source BIOS
equivalents for some of these architectures.

 Most important open source programs are easily recompiled for any
 architecture.

 (1) Try it and see, that's probably the easiest way.  Every laptop has
 an instrument in the battery that you can measure its power draw with.

Re: Notes from an impromptu 8.2.1 Release Mtg.

We are definitely recommending that they stop using MPP
mode (at least an automatic one.)

 A quick side-note here - reviewing the bugs listed there, I see we
 have a fix for dnsmasq in MPP mode, presumably for Uy.

 Are we recommending Uy that they stop using MPP mode?

 I think that there is fairly good consensus on that matter -- the
 reports of very bad RF saturation have been diagnosed to be cause by
 _all_ the laptops being in MPP mode. The RF saturation problems block
 any connectivity that you could hope to extend via MPP...

 That's such good news.
 
It's a bit broken, that addition to the anaconda file is unneeded, but
it uncovered the same bug that you ran into with kickstart on a fat

Not sure what to file this one against, looks like parted to me, as one

  - finds kickstart file without asking where it is...
 
 Good - does that depend on labelling the partition too? Do we have to
 change mkusbinstall to label it appropriately?
 
  - loader doesn't copy stage2 to RAM
 
 Cool -
 
  - fix compile error re: MD_NEW_SIZE_BLOCKS(size)
 
  - added support for method=hd:LABEL=XSRepo at the boot prompt
  This allows us not to ask where the install media if the usbdrive is
  labeled as XSRepo and passed the above string.
 
   - added support for mmc cards (for the XO) in loader. This is
  incomplete, loader now finds the CF card on the XO but is unavailable to
  partition and thus install to it. F10 has the same behavior, I filed BZ#
  481441. Hope they fix the issue before I have to dig it up
 
 I've CC'd myself on the bug. The actual number is - BZ 481431 -
 
Fat fingered that, sorry.

  - updated mkusbinstall added the labeling of the usbdrive for the above
  method and creation of /boot/olpc.fth for the XO.
 
 Ah, that's what I was alluding to earlier.
 
 Is it possible to workaround the SD card issue by building an
 installer image with an older kernel? From what you said it's a
 regression with 2.6.27.x right?
 
No, the issue is that anaconda, for F9, doesn't have the kernel modules
in the initrd, F10 does. Both fail to add the CF card to the
partitioning screen, thus making them unavailable as install targets.  

 I'm wondering if we can craft a just-installed image that can be dd'd
 to SD cards.
 
That seems do-able, I'll try on the weekend to work something up.

 I guess I'll explore this tomorrow -- I'm on the road today, so
 limited in my hacking ;-)

Re: [Server-devel] Upgrade to 0.5.1

2009-01-27 Thread Martin Langhoff
2009/1/28 Reuben K. Caron reu...@laptop.org:
 1. Which should be used.

Good spotting. Initially I thought kickstart could drive upgrades. It
cannot. So it's the one of the top options path that actually works.
I'll fix the wiki...

And at some point when we get a chance to improve the sysconfig menu,
we should replace those wonky menu options with ones that make sense
for us, including onecalled upgrade from 0.4 or vanilla fedora,
which of course includes the 'upgradeany' magic word.

 2. If you pass upgradeany to one of the top two options that does not use
 the kickstart, do you lose any functionalality?

You don't lose functionality. The 0.4 install has the two key pkgs,
xs-config and xs-pkgs. Anaconda upgrades both, and those bring in
everything that makes an XS.

cheers,
