github can be used as yum repo

[Martin Langhoff]

This might be of interest. OLPC has for a long time maintained sizable git
repos to support OOB.

For an unrelated project, I have just tested that the same thing can be
achieved with github.

For example, this repo:

  https://github.com/martin-langhoff/testfoo

can be used as a yum repo with this kind of url:

  https://raw.githubusercontent.com/martin-langhoff/testfoo/master/

note that the base URL returns 400, yum does not fetch 'index' pages from a
repo, it will request:


https://raw.githubusercontent.com/martin-langhoff/testfoo/master/repodata/repomd.xml

Re: [UKids] re:new member

[Martin Langhoff]

As Sam says xo-1 screens will work on xo-4 touch units. Disassembly and
reassembly of xo4 touch around the screen is delicate, careful with the
touchscreen data cable.

Over time we made small changes to the LCD screen but they don't make a big
difference. They all fit all production units.

XO-4s use the same screen as other XOs, but with an independent infrared
touchscreen on top of it.

There were some XO-1.75s that were modified to have more traditional
touchscreens to help with Sugar & XO-4 touch development.  These are mostly
in the hands of developers, and are rare.

Over time durability enhancements have been made to XOs.  But I don't
recall when what changes were made to the display.

In general I would recommend using a newer display with touch XO-4s to
reduce the risk of hard presses breaking the screen.

Not normal behaviour. It is consistent with a battery that has reached the
end of its usable/reliable life _or_ a battery that has unbalanced cells.

Note that this happens on almost every battery-powered device, not only
XOs, when batteries get old or their cells unbalanced.

IIRC wiki has instructions on how to try to rebalance batteries.

 Good idea; it may be the XO-4 kernel never had this feature working.
 The XO-4 with working tap-to-click have different touchpad model.

 CONFIG_MOUSE_PS2_SENTELIC=y is in .config, so this seems correct.

Re: Xubuntu on OLPC X-1

[Martin Langhoff]

Hi Hellaino,

that is a fairly complex path, there are a few dozen important tweaks and
configurations you need for it to run well.

You can probably get Fedora with XFCE, which will be very similar for end
users, by using OLPC's OS Builder (OOB) --
http://wiki.laptop.org/go/OS_Builder

If you really want Ubuntu, I suggest you first play with OOB, look at all
the tweaks it applies, plus the custom packages (olpc-utils, etc), and
study how to apply similar changes to xubuntu.

Minor changes to olpc-kbdshim and olpc-powerd

[Martin Langhoff]

From bz traffic, I think these packages are in the process of changing
to no longer auto-activate systemd services. Not sure which Fedora
versions these updates will land in.

olpc-os-builder should learn to activate them. I don't think F20
images work completely these days, I just wanted to mention this as
I'm sure it'll help.

The changed packages are in QA, so they'll land in a few days in... F20? F21?

EC, CForth exploratory commands?

[Martin Langhoff]

Hi folks!

Yesterday I ran a workshop covering some topics about hw development
and mfg. Using a lot of material from Bunnie's blog, as well as from
my time in the trenches.

As part of it I tried -- and mostly failed -- to give folks a tour of
early boot, using some old boards I have stashed. Here I got truly
lost. I could not find current useful notes on what you can do in the
early CForth env. I could also not find the commands for the EC port
in the wiki, though I do remember issuing commands on that port during
some testing...

I'm more familiar with the full OFW/Forth env so I kind of rescued my
pride there. The attendees got hooked so they're trying to drag me
into a second session in the coming weeks. It would be nice to revisit
EC port and early CForth with commands that actually work :-}

For simplicity sake, let's assume that I'm on XO-4 B1 or later. That's
what I have the most of, and what I suspect is the most interesting
anyway.

thanks in advance...

Fantastic info -- thanks!

Part of the story I am exploring is of why someone would want an EC
and a tiny early interactive runtime for debugging (i.e. during bring
up).

In related news, I'm poking around with u-boot for the Novena board
and maybe I'm missing some debugging tricks but it seems much harder
to debug. When it doesn't boot all the way to a working u-boot, well,
it doesn't and that's all you know.

Ahem. You are casting fugly accusations, you can't stand back and
thank everyone for their valuable feedback.

 2. Martin's point about the right hand not always being aware of what
 the left hand is doing. This unfortunately seems to happen too
 frequently.

Doing is the wrong word, AFAICS. Did anyone working for OLPC _who
was a maintainer to SL's trees_ ever rejected or actively ignored
patches like what you say?

The list of candidates is very short, and they are all highly ethical
professionals.

 I don't speak on behalf of the Association, but I think your positions
 are overstated. As far as I know, the Association is still pursing
 sales of XO laptops and is still supporting XO laptops in the field.
 Granted the pace of development is slowed and there is -- to my
 knowledge -- no team in place to develop an follow up to the XO 4.0. I
 don't have a clue as to what you mean by a technical philanthropy
 but it remains a non-profit associated dedicated to enhancing learning
 opportunities through one-to-one computing. The fact that the
 Association has private-sector partners is nothing new. It has had
 such partners since its founding in 2006.

+1 on Walter's words, David's position is overstated. OLPC has shrunk
its Sugar investment, that is true. But on the other points, nothing
has changed significantly, OLPC has always had to find sources of
funding.

 Given financial constraints, these are reasonable shifts.

That's more like it ;-)

 there are ways to establish publicly disclosed and mutually beneficial
 relationships. In the meantime we are happy to provide deployments
 support while seeding and supporting projects we feel are beneficial
 to deployments such as School Server Community Edition and Sugar on
 Ubuntu.

Seeding and supporting projects is how it's done.

I object very strongly to those statements; I hope it was not under my

Sugar and OLPC in all the time I was there.

While I didn't always agree or like AC's work or strategies, I have
been, on and off the record, always in favor of having a strong
ecosystem. AC being the main player in that space, this translated in
a strong advocacy for AC.

As a professional in the foss world, this is not something I would
accept in my team, and I don't think anyone in the team had the kind
of personality to play such games.

There were times where it was easy for OLPC to integrate patches,
There were times when it was hard. I tried to signal that in advance
because I have been on both sides of the integration game (and I
continue to be -- now with Moodle) and I profoundly despise games such
as the one being suggested.

 As a more incremental approach, Activity Central will continue our

From a deploy to XOs PoV that sounds like a ton of work. You'll
grind against a lot of little problems.

Fedora is no longer behind nor problematic. That was very much true in
earlier times. Some innovative things in Fedora (ie: systemd) have
been very well integrated with the Sugar stack. And some changes in
the Ubuntu pipeline are likely to cause some havoc.

From a work for AC customers already using Ubuntu, it probably makes
more sense. Still, the odd directions Ubuntu seems to be going are a
bit of a wildcard. I honestly hope that they settle a bit and make
life for their downstreams a bit easier.

 Oh, good. That clears it then.
 Thanks for the insight :-P

Perhaps repeated torsion on the board is one of the factors at play.
You may get a longer life out of it by ensuring that the unit is
tightly assembled (specially the screen, which gives the unit a lot of
its rigidity).

If you use the unit with the screen attached with only a couple of
screws, or those screws are not firmly screwed, the mobo is likely to
be getting more than its fair share of torsion. All the main frame
deserves a good tight assembly.

One question that I have in my mind is: assuming Yioryos' unit has
only glue in the corners of the CPU, does it make sense to add some
glue with a melting glue stick around the perimeter of the CPU casing?
[ I suspect the answer is no; the cheap melting glue sticks are
entirely unlike the glue used around the perimeter of the CPU... ]

Re: Customize default language with OS Builder

[Martin Langhoff]

Hi Lionel,

the right way for this is to have the correct language set in the
manufacturing data in the XO laptops. If you have this set right (and
you probably do already), then just include french in the build, and
on first boot the laptop will pick up the right default.

Boot one of your XOs, press escape to get into the OFW prompt (ok),
and type .mfg-data -- what does it print out?

cheers,

your questions in recent emails lack some background -- specifically,

 I guess that the “21007xx0.img” file is the “21021o0.img” file I’m looking

Changing track

[Martin Langhoff]

Hello devel!

I haven't been posting here often enough. After a year of enormous
effort, we are approaching start of mass production with XO-4. It is
time for me to announce my departure from OLPC.

My work at OLPC has been a demanding one and I have given it all my
energy. But I have a young family in a foreign country, and I find
that I need
to take things easier and find a bit more personal time.

It has been a great run of ~7 years with OLPC, ~5 of them with a
formal position in the organization, and it has been a great pleasure
to be part of this. Hacking, disagreeing and designing... looking for
a better widget, for a different world for our children.

I continue to be amazed at how hard it is... and at how much you
accomplish on the ground. But all those accomplishments involve more
hands than the members of devel@l.l.o (and related lists). A lot more
hands. We should always remember and respect the teachers and
technicians dealing with problems every day. Problems that may seem
trivial for us while we type an email or update a wikipage, but that
are huge when you don't know the fix, or your don't have the tools or
parts handy, and you are singlehandedly supporting a school of
hundreds of kids with XOs.

John Watlington will be taking over my responsibilities. We have in
fact been working as a team covering HW and SW with our respective
strengths.. We share style and background with OLPC. There is not much
of a transition to worry about, he has been involved in all major
decisions, including hiring me back in 2008 (now you know who to blame!).

I am not completely disappearing from the scene -- I'll stay on
devel@l.l.o :-) I will continue to be involved in e-learning projects
with Moodle and to be part of OLPC's extended family. Bear in mind I
cannot promise much time involvement -- I will be starting a new job
and prioritizing personal time.

My last day with OLPC will be March 8th. After that, mar...@laptop.org
will be no more, and martin.langh...@gmail.com is where you can reach
me.

let's keep hacking together,

 Hi,
 I have a simple question:
 when I use my XO-1, if I do nothing, after 15 sec, it changes to a
 middle-suspend : only the screen isn't off.
 So what I have to enable or disable to have the same on another init mod
 (init 2 for example)?
 Because I would to have the minimum of services (with my initdefault on
 starting up), without modificate my init (5). So for the moment, I have
 modificated the inittab, but now, I would to have the middle-suspend on
 inactivited use.
 How and what I have to do?

 Thanks in advance.

Re: XO-4 not resuming after suspend

[Martin Langhoff]

Does it have an 8686 (loads libertas driver) or an 8787 (loads
mwifiex* drivers).

Does it get better if you blacklist the wlan drivers, ensuring they
don't get loaded? You won't have wlan, of course...

At this point, XO-4 with 8787 is very stable for us, so if it has
8787, your report is a surprise, and we should diagnose further.

If you have an 8686, we are hunting down some regressions which may
explain what you see -- Paul Fox is working on it right now.

Great. Also the hw team is telling me that C1 units are more stable in

We don't have any C1 units to spare, but Ceibal should have a few of

That trac entry has the details of the fix, which involves changing
the main frame of the unit, but Christoph needs the preventative
workaround, which I don't think is described there.

The workaround is to put 0.5mm cellulose tape to act as spacer so that
the camera cable does not get folded so harshly. My rule of thumb is
as follows: when you look at the mainframe on the side where the
motherboard goes, you see an circular extrusion right on the other
side of the speaker would go.

Place the spacer in the middle of that circle. Does not need to be
large in terms of surface.

Put the motherboard + camera assy into place -- when you are in that
process, observe where the camera cable meets the mainframe and check
visually that the spacer is low enough that it will not pinch the
cable.

Re: Porting Sugar on Android (Ice cream sandwich)

[Martin Langhoff]

Hi Rajiv,

your plan seems to have good goals, but is missing some understanding
of what you can and cannot do.

You cannot run Sugar (a Python-based window manager, based on
traditional Linux sw stack) on the Android stack. Way too different.

To reach your goals, however, you could try something like...

 - identify what good Android Apps exist that match Sugar Activities,
those you don' t have to port, just replace :-) (ie: don't port
Record!)

 - those Sugar Activities that don't have an Android counterpart,
reimplement them as Android apps

 - Implement a shell -- replacing the standard Android shell -- that
has the main features of Sugar shell

 - Implement some of the key services that make Sugar special: ad-hoc
auto-networking, collaboration stack, the Journal. The most important,
IMO, is the Journal, as Android's handling of my files is extremely
poor. All these services will need integration into the shell and
apps.

Alternatively, you can wait for Android/Linux stack convergence
projects (see Jolla / Sailfish) to mature. Maybe in a year or two
there are ways to run Sugar inside Android or Android Apps on a Linux
stack.

hth,

 Same is the case when the XO is rebooted, while the modem is inserted. Upon

 I don't remember such issues in 12.1.0; there, the icon appeared whenever it

Interesting! If you remove the power plug, remove the battery and then
put the battery back in... the moment the battery connectors make
contact, the power LED should blink very quickly.

Does it happen in your unit?

Installed, quick test. You're right, the ebook trigger isn't
happening. And I cannot type with it -- Write won't show input from
the OSK, home view search box won't show input from OSK.

The touchscreen scale_{x,y} defaults are killing me. They make the UI
_very_ awkward to use -- I average 2.5 touches before I can hit a
moderately large button (next, or the stop icon). This is because
the offset the driver applies shifts in every spot of the screen, it's
a devilish thing.

Paul, can we crank those defaults way down? Or add a dampening / ramp
up effect to the offset that is flat in most of the screen, but
quickly ramps up near edges? (If you don't believe me, install OS5 and
use Sugar with the touchscreen for a while).

In summary... first step in a longish road. All ARM SoCs are quirky
and non-discoverable (no PnP-style bus architecture). The path leads
to a generic kernel that can read a list of known platforms, each of
those with its quirks and configurations listed.

The configuration-and-quirks facilty is known as DeviceTree.

We are definitely working hard in that direction, all our new kernel

qemu wine experiments on ARM

[Martin Langhoff]

Just a quick outline of one experiment to see if simple Win32
content-ware apps can be run. Commands may be missing switches,
options and steps. Caveat reader. BYO smarts.

On x87 host F17
 - install livecd-tools spin-kickstarts
 - copy fedora-live-mini.ks, add wine -- remove some stuff
 - sudo setarch i686 livecd-creator fedora-live-mini.ks
 - wait
 - copy resulting iso to ext disk
 - yumdownloader sgabios-bin-0-0.20110622SVN.fc17.noarch
seabios-bin-1.7.0-1.fc17.noarch -- they are noarch but missing from
arm repos. copy to ext disk

On ARM XO F17
 - install seabios-bin sgabios-bin rpms
 - yum -ty install qemu-system-x86 qemu-user
 - qemu-386 -m 512 -cdrom /some/media/fedora-mini.iso
   inside of the qemu window, in the live cd boot text menu press tab
to remove rhbg and quiet. boot slowly. Probably. Eventually.

Clearly, qemu can emulate x86 on ARM. Slowly. This is of course
impractical, mainly because you need to get through a bootprocess
before you can run an app and the app is not in a transparently shared
environment (it's in qemu's odd fb window).

Qemu's user-mode is a lot more practical. We would need a minimal
fedora x86 chroot that has wine, and use qemu over that. After a bit
of googling, I found PRoot, which seems to provide the right glue to
make qemu's user mode actually usable.

http://cedric-vincent.github.com/PRoot/
http://adt.cs.upb.de/quf/quf11/quf2011_13.pdf

For a truly minimal rootfs, mock is likely to be more useful than livecd-tools.

mock -r fedora-17-i386 --install wine

then tar up /var/lib/mock/fedora-17-i386/root, untar on your XO.

upowerd mystery of the day

[Martin Langhoff]

Hi Daniel, folks,

weird question of the day -- in the 12.1.0 series, have we fixed
anything that should affect how upower works indirectly?

While I was looking at our battery icon in Gnome, ~4 months ago, I
spotted upower spamming our logs because it could not find
/proc/timer_stats, with 6 messages per second.

Filed bug upstream, and upstream has now fixed it. Except that... the
spam disappeared from our logs before 12.1.0 went gold.

 - upower is unchanged from my report to 12.1.0 release.

 - We have some tweaks to /etc/UPower/UPower.conf that get applied
from OOB. Reverting those tweaks does not bring the spam back.

Do you have any idea of what may have affected upower?

It may still be platform-specific (I cannot recall what platform I
spotted this on, I just assumed it would not be platform-specific).
And if I really want it, I can try to bisect it, rolling back to
whatever build was latest in May 29th.

I've just checked with 1.5 and 1.75, which were the models I was
focussing on when we thought we had a video driver bug that didn't
update the battery icon. Also tested with low battery levels.

OS 12.1.0 does not have it. Very very odd.

I think it was /var/log/messages, but I've scanned lsof output there
is nothing suspicious. upowerd is logging to /var/log/messages, and
writing its own data files in /var/lib/upower -- those don't show any
errors.

I also observe that how do I return to Sugar? used to be visibly
obvious, and now it is fairly hidden.

 But its not clear to me if we want to do that by default (is that what

Yes, that's what I am proposing, and yes, I think we want it.

We will also need to tweak the height of top and bottom bar (and of
the buttons therein) to make them useful in a Touch UI.

Should be ok, as long as you're comfortable with the validity period

 2. Why is the XO adding this .asc extension or how can it be avoided?

As Sam mentions, it is MIME-Types. Perhaps this helps: set the mime
types in your webserver so that .sig files are served as
application/octet-stream (something that I believe sugar will not mess
with).

You can check what mimetype is being set on a transfer with wget --
during download, it'll print a message about Length, that same line
shows the mime-type.

If that doesn't help, let us know.

Glad that we found the reason. We should add an explicit check in OOB
that gives you a more useful error msg.

Compared with x86 builders, an XO-1.75 is fairly slow, and getting
fast ARM machines has been almost impossible. This seems to be
changing luckily. XO-4s will be fairly good builders I hope :-) and we
are trying to get our hands on early units of Kontron KTT30, which is
the only other ARM board we have seen that has CPU power and good disk

Others (like the ODROID Exynos boards) seem to have fantastic CPUs

 Instead, you should fix OOB so it works to cross-compile.

Unfortunately, OOB is just a nice wrapper around anaconda and rpm. You
cannot cross-build because

 - The anaconda toolchain does not have a good separation of
environment arch vs target arch, because you run the installer on the
target machine. This may be fixable with some effort.

 - rpm does not install cross arch because scripts (%pre/%post, etc)
often run binaries within the target fs. This is not fixable, unless
you run the rpm stage in an emulator. If you are going to invite an
emulator to the party, just do it around the whole process.

 - You don't invite an ARM emulator to the party because you want to
complete the build this year. ARM HW is slowish but bearable (build
time is ~1hr).

In practical terms, anyone building an OS image for an XO deployment
has access to an ARM-based XO. That drops the priority of
cross-building consistently.

TBH, I have never seen any OS image builder / composer in the Linux
world that works cross platform.

 Have anyone actually tried to emulate?

Not that I know. But I would expect it to be ~10x slower than on an
XO-1.75. And better hw should be available in the coming months, and
affordable ($200).

 Anyway, a load of work landed in Linux 3.6 to address this, to make
 the EHCI driver more resilient to odd hardware. Backporting to 3.3 is
 very simple, and fixes the problem. The commits in question are:

+1, though IANAKD so dilute it appropriately...

Re: Shipping bigger fonts by default for greater glyph coverage

Yes please! I made a half-hearted attempt at pushing for this in
12.1.0 cycle, and dropped the ball halfway.

 This will increase the base uncompressed OS size by about 6mb.

IMHO, this is tiny compared to the tradeoff at hand.

I mean tiny compared to the benefit. The tradeoff is completely desirable...

Fix the packaging, and don't use --force.
