Sounds like a fine idea to me, Martin.  Assuming we are accepted again
as a mentoring org, we should be eligible for more projects than last
year.  But do bear in mind that we may not get anyone interested in
those projects; and that a successful GSoC internship is primarily
about a good experience developing a meaningful product, and the
interns are free to define how to tackle the problem they undertake.

 GSoC

 GSoC is looming. I am thinking of putting some of the things that I
 was planning to do in the next X months as GSoC projects (and that I
 know I'm unlikely to hit).

 Ideally, I would take take 2 or 3 mentees, with a preference towards
 those who live in deployment regions...

Right now e28 is what you should be testing.  When the next f series

 Even when it isn't a total disaster, the cursor is still very hard to use.

 Sometimes it jumps to the lower left corner.
 
 Again, this is a B2 chasis with a B3 board.  If the cursor pad stuff has

In a B2 chassis you are going to see worse performance than later

And why do not have a MP (C2)?  Mail me your shipping address and I'll

Thats expected. You should not see any behavior change in the wlan by 
changing the system firmware.

The copy of the wlan firmware in the laptop system firmware is 
completely different than the copy of the wlan firmware that is in the 
OS build.

The system firmware has zero influence on how the wlan device operates 
wrt to association.  The only area where they interact at all is during 
suspend/resume and if you put the wlan into reset.

Its confusing since there are 3 different firmwares on the XO and the 
wlan is duplicated in both the system firmware and the build.  Often the 
wlan firmware in the system firmware is a different version than whats 
in the build.  The build will normally be the latest with the copy in 
the system firmware getting upgraded as necessary.

multitouch + audio feedback linux dev - XO-2?

2009-01-26 Thread Carlos Nazareno
Hi guys.

As a lot of you probably know, Intel just announced the Tablet
Classmate PC which has totally ripped off the XO's form factor 
functionality, upped the hardware specs  added touchscreen capability
(something I sorely miss when I switch from my nintendo DS touchscreen
stylus to the XO when testing stuff)
http://www.olpcnews.com/laptops/xo2/intel_beat_olpc_with_classmate_pc.html

Well, the XO still has it beat on price, low power consumption 
sunlight readability.
At $200 vs $499, I'd still take the XO any day. For $499, might as
well get a laptop with real horsepower. That's really just too
expensive for mass deployment, *ESPECIALLY* for public schools in 3rd
world countries (at least from a Filipino perspective).

Anyway, with dev on XO-2 in the works and with Pixel Qi working on
touchscreens from what I read, here are my questions:

1) Are there any existing hooks/systems for Linux for multi-touch?
That's the only proper way you can get a virtual keyboard to work for
a double-touchscreen clamshell device (the feasibility of which is not
sold to me because of the power consumption of running a 2nd screen vs
a keyboard, and mostly mostly mostly the lack of haptic feedback from
a virtual keyboard).

OT, but Honestly, as an electronic musician, the 1st thing that went
into my head when I saw the XO-2 concept shots was I could write
totally awesome DJ/live electronic software for this! because for it
to make any sense, multitouch would have to be in place. I don't have
programming experience w/ multitouch systems, but IMHO it should be
pretty easy- it would just be basically the same as simple 8-bit (or
1-bit) single color channel image recognition systems w/ pixel array
bytes substituting for pressure levels on each physical X-Y position
onscreen.

In fact, you could pretty much do multitouch systems with just a
camera (the XO's would be good enough, the machine would just need a
CPU with stronger horsepower to do the image processing :P) and any
surface where discrete image sections can be formed for img recog aid,
like using shadows from hands or maybe a color-reactive transparent
surface where if pressure or contact is applied, a particular color
shade (like a chroma key) will appear to aid img rec.

Btw, on-topic w/ multitouch, these engineering students from India
just came up with their own version of Jeff Han (NYU  Perceptive
Pixel)'s FTIR multi-touch tech, Sparsh http://www.sparsh-i.com/ -
totally awesome and they showed a DJ app too!

So back to the question: any existing Linux multi-touch hooks/drivers/APIs?

(btw, refresher on Jef Han's multitouch tech: http://www.perceptivepixel.com/)

2) Audio feedback
A big problem with touch-screen/virtual keyboards is lack of haptic
feedback (and haptic feedback would probably eat batteries a lot). A
standardized/universal audio mapping to keyboard keys similar to
QWERTY, Dvorak or Braille would help solve this. This has actually
been an interest of mine for the longest time because blind/visually
impaired computer users could have a hard time with non-haptic
keyboards or non-standard keyboard key locations. Also, this would be
a great aid for blind coders, one would be able to code  read case,
punctuation  special characters via tone-mapped keymappings and
playback. Yes, text to speech and screen readers exist, but I think
they're pretty useless for blind coders with a need for speed. Can you
imagine running PERL through a text-to-speech system?

A cool side effect of this would be that any kind of text would be
translated to music via tonemapping or whatever audio cues are used :)

(sorry guys, am a synaesthetic, all sensory data can be translated
into numbers and be remapped to any other sense :P)

Well, these 2 topics are very big undertakings but does anyone know
any good starting points? If not, are any of these being researched at
1CC/Media Lab? I'm very much interested in researching/studying these,
especially the long-term study for the HCI development/creation of a
cross-platform internationally standardized keyboard/character/unicode
tone/sound map (reconfigurable by users).

Many thanks!

 feedback (and haptic feedback would probably eat batteries a lot). A
 standardized/universal audio mapping to keyboard keys similar to

I have some insight into this topic from experience in the cell phone
industry. There are several ways to do haptic responses: linear vibrators,
piezo-electric elements, speakers. Localized haptics are best (the vibration
comes from the area on the screen that has been touched), but that's still
an emerging technology. The challenge with your idea is latency. For
applications like typing, the haptic response must happen very quickly to
trick the brain into thinking it is related to the press. I think I've heard
the number 25 ms before, but don't quote me on that. A quick google search
couldn't confirm or deny this. I did find an interesting paper (
http://aig.cs.man.ac.uk/people/jayc/jay_quantifying_latency.pdf) that stated
100-200 ms was the limit, but I don't think the results apply to typing. The
game in their experiment took a second to complete, which is way longer than
a keystroke takes. If you don't care about typing repeatedly, the latency is
less important. But for typing quickly with a  limit of 25 ms, it will be
hard to interrupt the processor, load a sound file, and play it in time. A
dedicated microprocessor might be up to the task though.

Also, I'm not sure if a speaker would draw significantly less power than a
piezo or linear vibrator. I don't remember hard numbers for either use case.

Thanks,
Nate

Re: multitouch + audio feedback linux dev - XO-2?

2009-01-26 Thread Wade Brainerd
My (unasked for) opinion is that multitouch should not be a focus of OLPC's
development efforts.  The real benefit will just come from being able to
touch the screen in the first place.

Writing a decent multitouch interface requires massive UI design and coding
efforts that we frankly cannot muster right now, and the concept is so
immature in the Linux world that we cannot rely on someone else to do it for
us.  A real multitouch device would require a development effort similar to
what Apple put into the iPhone, that is hundreds of engineers over several
years with absolute control over the software stack.  Given financial
realities that's just not going to happen with XO-2.

That said, here's hoping the final solution is pressure sensitive!  The
Nintendo DS gets all kinds of wonderful features out of that, and it's
already part of XInput.

  That's the only proper way you can get a virtual keyboard to work for
  a double-touchscreen clamshell device (the feasibility of which is not
  sold to me because of the power consumption of running a 2nd screen vs
  a keyboard, and mostly mostly mostly the lack of haptic feedback from
  a virtual keyboard).

  So back to the question: any existing Linux multi-touch
 hooks/drivers/APIs?

 there has been some discussion on the kernel mailing list recently. they
 are still hammering out what reasonable APIs will be (different
 multi-touch systems provide different capabilities)

Re: multitouch + audio feedback linux dev - XO-2?

 My (unasked for) opinion is that multitouch should not be a focus of OLPC's
 development efforts.  The real benefit will just come from being able to
 touch the screen in the first place.

 Writing a decent multitouch interface requires massive UI design and coding
 efforts that we frankly cannot muster right now, and the concept is so
 immature in the Linux world that we cannot rely on someone else to do it for
 us.  A real multitouch device would require a development effort similar to
 what Apple put into the iPhone, that is hundreds of engineers over several
 years with absolute control over the software stack.  Given financial
 realities that's just not going to happen with XO-2.

 That said, here's hoping the final solution is pressure sensitive!  The
 Nintendo DS gets all kinds of wonderful features out of that, and it's
 already part of XInput.

 Imagine the possibilities of a screen that can become any kind of keyboard
 you can imagine (computer, piano, drum, painting canvas, etc).

 Here's to staying focused,

agreed, but I don't see how you can do a keyboard and not have some 
multi-touch stuff (shift keys to start with)

I am in the group that has serious doubts about the current XO-2 design. I 
suspect that when push comes to shove the idea of the second screen being 
the keyboard will go the way of the crank in the XO-1

Thanks for the pointer.

When using those functions I receive the following error message:
RuntimeError: To make asynchronous calls, receive signals or export

be attached to a main loop by passing mainloop=... to the constructor  
or calling dbus.set_default_main_loop(...)

It seems like a code fragment was missing from the file,
and in my particular application, I wouldn't mind if those calls were  
synchronous --- how do I do so ?

Re: [Server-devel] GSoC 2009?

2009-01-26 Thread Samuel Klein
Sounds like a fine idea to me, Martin.  Assuming we are accepted again
as a mentoring org, we should be eligible for more projects than last
year.  But do bear in mind that we may not get anyone interested in
those projects; and that a successful GSoC internship is primarily
about a good experience developing a meaningful product, and the
interns are free to define how to tackle the problem they undertake.

 GSoC

 GSoC is looming. I am thinking of putting some of the things that I
 was planning to do in the next X months as GSoC projects (and that I
 know I'm unlikely to hit).

 Ideally, I would take take 2 or 3 mentees, with a preference towards
 those who live in deployment regions...

Who handles that stuff (application as an org, etc)? Have we applied,
do we need to apply? IOWs, who do I hound?

For good or bad, I'm a veteran mentor of 2 GSoCs, I hope that some of
the subprojects I'm thinking of are compelling :-)

Most of this year I've been doing the unsexy, burdensome plumbing,
deferring the fun stuff. If GSoC'ers grab the fun stuff, more power to
them.

 latest re-roll of anaconda, srpms, rpms and patch used, updated
 mkusbinstall for the XO at:

 http://members.shaw.ca/jvonau/pub/anaconda/

That's such good news.

 - 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 -

 - 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?

I'm wondering if we can craft a just-installed image that can be dd'd
to SD cards.

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