Image Sensors World: Tessera Q2 2010 Results

Copyleft Hardware - 7 hours 58 min ago
Business Wire: Tessera announced its Imaging & Optics revenue was $9.5M in Q2 2010. This was up 43% compared to second quarter 2009 Imaging & Optics revenue of $6.7M.

Q3 2010 Imaging & Optics revenue is expected to be approximately $10M vs $7M in Q3 2009. Still, there is some way to go to reach Hank's EDoF revenue target of $100M in 2011.

Bunnie Studios: Name that Ware July 2010

Copyleft Hardware - 11 hours 15 min ago

The Ware for July 2010 is shown below. Click on the image for a much larger version.

This ware is not a functional ware, but rather a work of art. I’m a little worried this might be too obscure for the competition, but I did a check on google, and the right keywords produced images of this artifact. If it turns out this is too hard to guess, I’ll release some more hints over time.

Bunnie Studios: Winner, Name That Ware June 2010

Copyleft Hardware - 11 hours 16 min ago

Thanks to everyone who played last month’s Name That Ware! I was astonished at the number of people who made a huge effort to count all the vias.

Before I announce the winners, I’ll reveal the design stats on the number of vias on the PCB:

144 9-mil vias
1062 10-mil vias
13 13-mil vias
15 162-mil vias

For a grand total of 1381 vias. This would make Alex G the winner at 1379 vias. Congrats, email me to claim your prize!

Talpadk: Bleading edge the freesmartphone killer?

Planet Openmoko - 14 hours 51 min ago

Ok, maybe not the killer but then at least the delayer.
But it did get your attention right?

As usual I am struggling just to get the phone working as a receiver of SMS messages.
Trying to figure out where gsm0710muxd writes it log files by default I fetched the source.

I know it is sort of deprecated but I’m trying to get my Debian based install up and running.
And the Debian dependency graph lists it as a dependency of fso-frameworkd…

gsm0710muxd states: THIS_IS_DEPRECATED_USE_LIBGSM0710MUX
libgsm0710mux states: DEPRECATED_PLEASE_USE_CORNUCOPIA
And of course there is also
fso-abyss.git the “GSM 07.10 Multiplexer (NG)” (which is deprecated in favour of cornucopia)

To sum it up we have 4 different implementations of a GSM multiplexer… no wonder I am a bit confused which to use.

But why not just “apt-get install cornucopia” and leave the past behind?
Well I would but unfortunately it seems that the bleeding edge phone software needs a bleeding edge “valac 0.9.3-3″
which even the vala developers consider a development release which prevents it from entering the Debian unstable distro.

Being a fan of C and C++ (if you can spare the “disks” space for the std. library)
I sure would have preferred if the more proven and stable platform  C were used than this new kid on the block valac
which I did not even know existed prior to its usage on the Neo/Freerunner.
It sure would make it easier to port it to other distros than SHR.

And then there is SHR and the whole home-grown Illume 1and 2 issue, focus bugs, all new bugs in V2 (I have not tried it as the mailing list scared me away).
Being slightly conservative with regard to this whole new software ting. What is wrong with say matchbox as far as I know it mostly just works.
Okay it is not thumb friendly per standard, but a little themeing seemed to do the trick for Nokia and the 770/800/810.
And GTK seems to do the trick for my desktop PCs, and it seems slightly more stable that the fancy Enlightenment tool kit.
At least I can not remember having any problems giving focus to a text input field.

But is  SHR not the  most advances phone distro?
It is, however it lacks the diversity of available packages of Debian, and I find the the build system beaks way to easily for my taste.

Why do I believe that all this may be harmful?

  • If there are lots of things that do not work you are more tempted to not use the FSO phone this includes UI misfeatures.
    I once used it as my primary phone but have reverted back to an ancient Nokia 6100.
  • Using new tools makes it harder to gain support from the community as less people know them.
  • Lots of rewrites causes bad documentation, as no one has the time to write it.
    It also makes it harder for the occasional hacker to get anything done as everything is new at each rewrite.
    It also puts an increased strain on other distro maintainers as they have to keep up, not only with the new services but also the new dependencies.

Last but not least:
Remember the ones writing the code is always right.
If you don not agree with them do not write blog entries, write code.

To: Michael ‘Mickey’ Lauer, the SHR and Pkg-FSO team
Keep up the good work, I can not imagine how you get any real life activities done as well as coding this much.

John Sullivan: Presentations at Debconf in NYC

Planet Openmoko - Sat, 2010-07-31 07:46

I'm excited to be giving two presentations at Debconf 10, held this year on the Columbia campus in New York City.

The first is "FSF's Campaigns for Freedom" on Sunday, August 1st, from 14:00 to 15:00 in 414 Schapiro. I'll give an overview of some of the current FSF campaigns, like the GNU Project, Working Together for Free Software, Defective by Design, PlayOgg, Windows 7 Sins, and the High Priority Projects List; and resources like the Licensing & Compliance Lab, Free Software Jobs page, Hardware Directory, and the Free Software Directory. But I'm going to save plenty of time to talk with the room about things the FSF should or could be doing.

The second is "Patent Absurdity: How software patents broke the system" on Thursday, August 5th, from 14:00 to 15:00 in the Davis Auditorium. We'll be watching the Patent Absurdity film, chatting about what's happened since, and what the Bilski decision means for the future of free software.

I'll be around the conference all week, so drop me an email at johns@fsf.org or catch me in the #debconf channel (johns) if you want to chat about the FSF or GNU.

Harald Welte: GSM Denial of Service by flooding BTS with RACH requests

Copyleft Hardware - Sat, 2010-07-31 04:00

At Blackhat US 2010, there was a Talk that (among other things) apparently included the subject of a RACH DoS on GSM base stations, implemented using my Layer1 of the OsmocomBB software.

As some news sites are covering this as "news": This vulnerability has been long known in the field and was - to the best of my knowledge - first demonstrated to a public audience by Dieter Spaar at the Deepsec 2009 conference in November 2009. You can get his slides.

The difficult part for many years has not been to know about the possibility of this weakness. Anyone who has read the GSM air interface specification will inevitably see that there is a limited number of RACH slots and a limited number of dedicated channels. Once you fill more RACH slots than the cell has dedicated channels, and you keep re-filling them at a higher rate than the cell can expire those dedicated channels, you have a DoS.

So rather, the difficult part was to implement it in practise, as traditionally all GSM baseband chipsets have been extremely closed, just like the very software (firmware) running on them. Today, starting from Q2/2010, it is very easy to do a proof-of-concept implementation, as we have created OsmocomBB: An Open Source baseband firmware.

Dieter Spaar's implementation predates OsmocomBB development by the better part of a year. At that time, he had to resort to binary-patching existing proprietary (binary-only) baseband firmware. So I think people should recognize his effort in doing the first practical implementation of that attack.

I can only hope that the author of the Blackhat presentation has given proper credits and shown that neither OsmocomBB, nor the RACH DoS attack, nor the IMSI DETACH attack he has presented have been discovered or first published by him.

Ya se que alguien se creo el suyo casero, yo me cree mi TVout casero, pero prefiero comprar uno original...

mi idea seria juntar estos dos:

http://www.hardcore-gamer.net/tienda...oducts_id/9517
http://www.hardcore-gamer.net/tienda...oducts_id/9516

para poder tener un usb host para otro mando usb y jugar a dobles, seria viable sin soldar los pins? se se tendria que soldar los pins se uno al otro, que solo sea un EXT?

a ver si sale y me los pillo y hago pruebas...

Un saludo!!!

Harald "LaF0rge" Welte: A real-world practical A5/1 attack using airprobe and Kraken

Planet Openmoko - Fri, 2010-07-30 04:00

At Blackhat USA 2010, Karsten Nohl has been presenting on a practical real-world A5/1 cracking attack. For recent years, Karsten, myself and others have been speaking at various opportunities, indicating that a practical attack using readily-available information and tools from the Internet is very possible, and that it is only a matter of time for somebody actually does it.

While Karsten has focused on the actual cryptographic attack, I've been putting in some time in projects like airprobe (a GSM receiver/decoder).

Now finally, a team of friends at the new Security Research Labs (founded by Karsten) in Berlin has put the pieces of the puzzle together.

Airprobe has been extended to fully support decoding of TCH/F (FACCH, SACCH and traffic), as well as SDCCH/SACCH control channels, and to specify the timeslot and physical channel configuration from the command line. Using this, you can

  • decode the AGCH, wait for an IMMEDIATE ASSIGNMENT of a SDCCH
  • decode that very SDCCH and wait until encryption is turned on
  • dump an encrypted burst where you have sufficient known plaintext
  • use a different program to actually recover the A5/1 ciphering key
  • feed that key into airprobe and decrypt+decode the ASSIGNMENT COMMAND of the TCH
  • use airprobe to decrypt+decode that assigned TCH/F

The external program to recover the A5/1 ciphering key is called Kraken and is also available from the SRLabs website.

So what are the limitations? Well, so far this only works on non-hopping cells with a single ARFCN. The limitations are those of the receiver hardware (and SDR software), and not really limitations of the airprobe GSM decoder or the actual software tools.

In the past I would have assumed that non-hopping and/or single-ARFCN cells are rare, but in fact we can find them even inside a big city like Berlin, from at least two of the four German GSM operators. So that's why this attack is very practical, no matter what the GSMA might say.

Comisiones que voy a pagar de mi bolsillo para el concurso

Foro GP2X the Wiz de gp32spain - Thu, 2010-07-29 22:52
Buenas:

Estoy haciendo recuendo de las donaciones recibidas, para ver si hay algún error (falta alguno o he puesto alguna cantidad mal) y me sale que de mi bolsillo voy a tener que poner 201,77€ (sin contar los 600€ que doné) por las comisiones que me ha clavado paypal en cada donación recibida. Viene a ser un 10% de todo lo donado.

Si hago algún otro concurso en el futuro (estoy algo escarmentado), tendré que poner en las condiciones que del total donado se restarán total las comisiones cobradas por Paypal, porque esto es una sangrada.

Encima, cuando haga las transferencias a los ganadores, a ellos volverán a cobrarles una comisión. Menudo negociaco tienen montados estos tios...

Chris Lord: Pill popping and happy wombats

Planet Openmoko - Thu, 2010-07-29 12:29

Damien, Neil and I gave our joint talk about doing interesting and unusual things in Clutter yesterday. I think it went down alright, hopefully we can give more of this kind of talk in the future, showing people how you can use Clutter in cool ways.

For my part of the talk, I spoke about developing small, fun games. I intended the advice I gave to apply to developing any small game with anything, though it definitely applies to making games in Clutter. You can find the text and slides for my talk here. Like Neil and Damien (and the rest of the Intel OTC crew), I wrote my talk in pinpoint, pippin's excellent, new, Clutter-based presentation tool.

I wrote two games before the talk:

Both of these games are available from my git repository. Pill-popper works with any recent version of Mx and Clutter, Happy Wombats currently requires master clutter-box2d and the 'kinetic-scrolling' branch of Mx (which should shortly be merged - I'll update this post when it is). When these games are more complete, I hope to submit them to the MeeGo garage, and perhaps suggest their inclusion for gnome-games.

Happy Wombats includes an editor, so I'd love to receive some levels at some point. I'll be improving things soon, but it's already quite easy to use. Guadec has been great so far, I hope we can keep up the momentum of awesome developments until the next one :)
