Turning off the mesh to save battery power

2009-01-27 Thread Bryan Berry
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

You've got a point about the keyboard, in my haste to rant I totally
sidestepped that :)  A piano keyboard would be pretty lame if it didn't
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
the hardware supports multitouch, a custom API should be developed just for
the keyboard based on instantaneous pressure.  Multi-pointer would be
overkill to a simple solution.

[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

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

2009-01-27 Thread Carlos Nazareno
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.

Cool.

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
processor and an ARM to boot a small linux distribution from flash, so it
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.


 As for games, can we just classify the XO in the same class as

 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!)

Right you are, I love this little piece of hardware.
Best regards,
 Tiago Marques

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.

For example, the kind of behaviour that you see when connecting to

Every other (useful) protocol I can see in my /etc/services breaks if
you try this stuff. Maybe some limited interactions work -- like with
SMTP -- but overall, it just doesn't work.

We can muck with HTTP with a transparent proxy that allows us to serve
some remote URLs locally. I want to avoid it, but if we have to do
it, we will. Every other protocol - I plan to leave alone :-)

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.

From the comment:


begin quote

AMD is NOT halting production of the Geode. They are not leaving the
market (RTFM!). They have decided that it serves it's niche AS IS and
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).

(http://www.soekris.com/) when I was doing fun Wi-Fi stuff, and used

I'll also point out (peripherally) to a comment made by Jeff Bezos in

(http://www.businessweek.com/magazine/content/08_17/b4081064880218.htm),
where he says that frugality leads to innovation (necessity being the

has definitely lead to many innovations. I for one would *not* have

 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 
filesystem.

Not sure what to file this one against, looks like parted to me, as one
of the booty functions import parted.


  - 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,
