Tizen Developer Conference 2013 Presentation Slides, Audio Recording and Videos Are Now Available

July 28th, 2013 No comments

The Tizen Developer Conference took place in San Fransisco, on May 22-24, 2013. We’e already seen a few Tizen demos from the conference, but slides and media files (mostly audio, but also some videos) are now available for keynotes and technical presentations.


As this was just the second Tizen conference, there were still many sessions dealing with overall structure of the operating system, and explaining how to get started either with native or web development, such as:

Tizen enters a mobile world dominated by Android and iOS, so several sessions targeted app developers used to work with either operating systems in order to show them how to port their existing apps to Tizen:

Of course, they were also sessions, probably a bit more technical, focused on development of specific features:

And many more, as media files and slides are available for nearly 60 sessions and keynotes.

There’s also a 2-hour developer’s lab (Devlab) session entitled “Creating a Tizen Application: Start to Finish” divided into four parts:

  • Tizen Contest Announcement overview with Brian Warner and Distribution of Tizen USB Drives with Wesley Osaze
  • Tizen Native API Overview with Hod Greeley
  • Tizen Web API Overview with Bob Spencer
  • Live Code Session Overview with Stewart Christie

Tizen Shows Up in Smartphones, Ultrabooks, and Cars

May 25th, 2013 1 comment

I’ve seen a lot of tweets about Tizen in the last fews days, mainly because Tizen Conference 2013 just took place. First there’s been Tizen 2.1 SDK release, and few demos have surfaced,  showcasing Tizen in their target devices: smartphones, tablets,smart TVs, laptops, and In-vehicle infotainment devices. Beside all the work done, the companies behind the project will also offer $4 million to developers who publish apps on Tizen store. There will be 9 categories. The best 3 games will get $200,000 each, and the best apps in the other 6 categories $120,000 each. Tizen App Challenge will start on June 3, 2013, and you can see details for this program here.

Let’s see the demos. First Tizen in Samsung developer smartphone running Qt 5.1, and the usual Qt5 Cinematic Experience demo, as well as 2 others apps, both super smooth. (via TizenExperts). You can find more information in Qt for Tizen page.

This is not the first time we see Tizen running on Samsung Developer platform, but Qt5.1 is very recent.

The next demo shows Tizen running on an Intel Core i7 Ivy Bridge UltraBook at Tizen Conference 2013 via TizenExperts. The desktop environment is based on GNOME 3 Shell, and beside the HTML5 apps, you’ll be able to run applications such as LibreOffice and Chrome, just like in any other Linux distributions. They also demo Stream in the device, running Team Fortress 2. Finally, they showed Tizen SDK, developing Tizen Apps, and running an OpenGL accelerated smartphone simulator.

Overall, I find the experience feels a little like Ubuntu. Th demo shown above runs the latest Tizen 2.1, but laptop support should be officially part of Tizen 3.0 release.

Jaguar Land Rover, Intel, and the Linux foundation collaborated to create the last demo I’ll show today (via TizenTalk). It’s an in-vehicle infotainment systems (IVI) running Tizen in a Land Rover. It features a standard car interface, support for gstreamer to play audio and video, a demo app store, and a demo GPS positioning system app. The demo is not a product per say, it’s said to be a fully open source demo, so that other people can work on it. You can find the detail on Linux Foundation Automative Grade Linux (AGL) page.

If you’re particularly interested in the work done for “alternative” mobile operating systems with project such as Sailfish, Mer, Tizen, and Qt, on ARM and x86 hardware, you may want to follow @vgrade on twitter.

$21 CARAPP APP327 Bluetooth OBD2 Car Diagnostic Scanner

February 26th, 2013 9 comments

As cars become more sophisticated, you’re now able to access all sort of data from your car and display this on a computer or tablet to diagnose problems or simply to create your own high-end dashboard. This morning, I’ve come across CARAPP APP327, a Bluetooth diagnostic scanner compatible with OBD2 standard (On-Board Diagnostic II), which could can just connect on an OBD2 connector if your car is recent enough. This has been around for many years (since 1996), but I had never heard about this technology until today.

OBD2 Connector (Left) - CARAPP APP327 Bluetooth Scanner (Right)

OBD2 Connector (Left) – CARAPP APP327 Bluetooth Scanner (Right)

Wikipedia OBD2 page explains the OBD2 connector (16-pins) should be within 2 feet (0.61 m) of the steering wheel according to the standard, which also specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, and the messaging format. After you connect the Bluetooth adapter, you just need to install the applications needed for your platform (e.g. Android, Windows, iOS, etc…) which you can get from an installation CD, or download an application that supports OBD2 standard such as Torque Pro or Torque Lite for your Android device.


Torque Pro User Inteface

Let’s go back to CARAPP APP123 and its key features:

  • Function – Read trouble codes, check trouble codes, display current sensor data, calculate fuel oil consumption.
  • Wireless – Bluetooth with a transmission range up to 10 m
  • Interface – 16-pin OBD2
  • Software Platforms – Android, Win XP / Win 7 / PPC (Windows Mobile)
  • Protocols Supported – ISO15765-4 (CAN), ISO14230-4(KWP2000), J1850 PWM, J1850 VPW, ISO9141-2
  • Output Protocol – OBD2 @ 115.2Kbps
  • Power – 12 V / 35 mA working current

The device can report the engine and vehicle speed, load values, the temperature of the cooling liquid, the fuel system status, short-term fuel adjustment, long-term fuel trim, the air flow rate, oxygen sensor voltages, fuel pressure and more. Since it follows OBD2 standard I would think it’s compatible with Torque Pro/Lite, but could not find specific demo videos for this particular device.

CARAPP APP12 costs $21 on Dealextreme, but other cheaper and more popular ODB2 Bluetooth diagnostic scanners are also available such as Soliport ELM 327.

A Selection of FOSDEM 2013 Events

February 1st, 2013 No comments

FOSDEM is a 2-day (or 3 if you include Friday beer event) event where over 5,000 members of open source communities meet, share ideas and collaborate. It’s free to attend, and there’s no registration, so you just show up to attend. FOSDEM 2013 takes place on Feb 2-3 (yep, this week-end) in Brussels

There are 7 main tracks where sessions are organized:

  • fosdem logoOperating systems
  • Open source challenges
  • Security Janson
  • Beyond operating systems
  • Web development
  • Miscellaneous
  • Robotics

There are also keynotes and devroom for a total of 488 sessions. Developers rooms that may particularly be of interest to readers of this blog are:

All in all that’s a lot of sessions, and even though I won’t attend, I’m going to select a few from the main tracks:

This talk introduces the Fedora ARM Project and in particular the work we are doing to bring Fedora to emerging 64-bit ARM server systems.

Where are we today, one year after the unveiling of the Lima driver. This talk will cover the Lima driver (ARM Mali 200/400), but also other open source GPU driver projects such as the freedreno driver (Qualcomm Adreno), open source driver for Nvidia Tegra, etnaviv project (Vivante GC) and cover the status for Broadcoms Videocore and Imaginations PowerVR GPUs.

Based on the speaker’s experience of getting the support for the new Armada 370 and Armada XP ARM processors from Marvell into the mainline Linux kernel, this talk will detail the most important steps involved in this effort, and through this, give an overview of those changes and summarize the new rules for ARM Linux support.

  • Sunday 11:00 – 11:50 – Firefox OS by Jonas Sicking

Firefox OS is the next product being developed by Mozilla. It’s an open source OS based on the web and following the principals which have made the web a success. A phone running recent builds of Firefox OS (it’s not a finished product yet) will be demoed, and  the technologies and ideas behind Firefox OS will be discussed.

The systemd project is now two years old (almost three). It found adoption as the core of many big community and commercial Linux distributions. It’s time to look back what we achieved, what we didn’t achieve, how we dealt with the various controversies, and what’s to come next.

How Aldebaran Robotics is using open source on their NAO robot.

This talk will provide an overview of the Robot Operating System (ROS), an open software integration framework for robots.

This talk describes how the automotive industry has moved to embedded Linux and Open Source to develop the next generation of In-Vehicle Infotainment (IVI) and how it has met the challenges along the way.

What, why, when, where and how SecureBoot changes the way we build F/LOSS
