Canonical Unveils Ubuntu on Tablets

Yesterday, Ubuntu.com displayed a time counter for an announcement reading “Tic Toc Tablet Time” that ended being about Ubuntu on Tablets, and not an HTC Tablet running Ubuntu as some blogs speculated, as both companies had a timer counter set to expire at the same time for separate, and unrelated, announcements. The interface looks very much like Ubuntu for Phones with a similar “Welcome Screen”, except multiple users are supported, no icons (except for apps), and you can swipe around the 4 edges to access the dash, opened applications, notifications, and more. Canonical highlights 5 key features for Ubuntu on Tablets: Real multitasking – Run mobile and tablet apps at the same time on the same screen Secure multi-user Voice controlled HUD productivity Edge magic for cleaner apps – As I said previously no buttons, you control eveything from the edges. Content focus – Messages and media are easily accessible […]

Ubuntu Linaro 12.11 with 2D/3D Mali-400 GPU Acceleration on ODROID-X Development Board

A few days ago, Hardkernel released the first version of Ubuntu 12.11 (Linaro) with Mali-400 GPU support for their ODROID boards (ODROID-X/X2, ODROID-U/U2). This is still WIP (Work in Progress), but this is one of the few boards together with Pandaboard, Origen and Snowball that can support 2D/3D GPU acceleration in Ubuntu Quantal. Since I have an ODROID-X development board, I decided to give it a try. There are different ways to install it. I chose the way that is most convenient for me (LCD display instead of HDMI), and likely to yield more performance (eMMC instead of SD Card). The current installation instructions to eMMC are extremely cumbersome and you have to go through 5 main steps: Install Android (yes, seriously) in the eMMC Install Ubuntu in the SD Card Install Ubuntu to the eMMC Upgrade Ubuntu to the latest version Install the Mali drivers In this post I’m […]

Linux 3.8 Release

Linus Torvalds has announced the release of Linux Kernel 3.8: The release got delayed a couple of days because I was waiting for confirmation of a small patch, but hey, we could also say that it was all intentional, and that this is the special “Presidents’ Day Release”. It sounds more planned that way, no? Anyway, the really good news is that things calmed down a lot on the last week. There are noticeably fewer commits, and they are also all quite small. The few commits with more than just a couple of lines tend to be due to a couple of reverts, and two architecture patches where some identifiers got renamed (tile), or some defines got moved from the uapi file to a private header (x86). And there’s one radeon patch that uses a helper function instead of reading bytes directly. And even those “bigger” patches weren’t really that […]

How to Open an Android mini PC / HDMI TV Dongle

Since I’ve been asked, I’ve done a short video showing how to open an Android mini PC, namely Droid Stick A2. As most casings are based on similar design the same method can be used for many other mini PCs that comes with a plastic casing. Some other mini PCs with a metallic casing, such as Hi802, need to be opened with a different, and IMHO easier, method as you just have to remove 2 screws. For Droid Stick A2, all you need is a flat head precision screwdriver. First look for small spaces between the two parts of the casing, insert the screwdriver where the largest space is, and gently lift it up. Watch the video below for a demo.

Weightless Overview and Neul Iceni, The First Weightless Chip

The Weightless Special Interest Group (SIG) has recently announced the world’s first transceiver chip using the Weightless Specification and operating over white space spectrum. Neul Iceni chipset makes use of the entire TV white space spectrum to provide low power connectivity for M2M and IoT applications using the Weightless Standard. Weightless Standard Overview Since this is the first time I write about the Weightless standard, let’s see what it is and what will be used for. There has been a lot of talk about the Internet of Things (IoT) and machine to machine communication (M2M), but one of the limiting factor is currently the cost of technology (and networks?) to provide communication. That is where “white space” spectrum comes into play. A large spectrum was used by analog TV channels, and since many countries have now switched to digital TV, part of this spectrum is unallocated (hence the name “white […]

PQ Labs iStick A200 Android mini PC Connects to G4 Series Multi-Touch Screens

PQ Labs iStick A200 is a Rockchip RK3066 Android 4.1.1 mini PC with 2 GB RAM, 4 GB Flash, an HDMI (female) output, a USB 2.0 Host port, and a miniUSB port for power. Pretty boring stuff if you ask me… And I would not be writing about it, if the company hadn’t interfaced their infrared touch frames to this mini PC to allow 10-point multi-touch on a large screen or projector output, making it a pretty good solution for conferences and interactive digital signage. Before going further, let’s have a look at the details of specifications for the iStick A200: SoC – ARM Cortex A9 Dual Core @ 1.6Ghz with HyperSpeed (Equivalent to 2.0Ghz Dual Core) and Quad Core Mali400 GPU (cnxsoft: It has to be Rockchip RK3066) System Memory – 2 GB DRAM chipset Storage – 4 GB NAND flash + microSD socket (Up to 32 GB) Video […]

ARM big.LITTLE Processing Demo (HMP) on ARM TC2 Test Chip

Samsung launched Exynos 5 Octa at CES 2013. This processor comes with 8 cores: 4 Cortex A15 cores and 4 Cortex A7 cores, and it’s the first processor that’s been announced to work in big.LITTLE configuration, where the big cores (A15) handle demanding tasks, and the LITTLE cores (A7) handle simpler tasks such as audio playback or background tasks. This is all done to optimize power consumption. There are 2 big.LITTLE software implementations: In-kernel switcher (IKS) and heterogeneous multi-processing (HMP). The first one is easier to implements but can only use 4 cores (in Exynos 5 Octa) at a time, and the second is more complex, but can handle all 8 cores, and assign individual tasks to a particular core. For more technical details about big.LITTLE implementations, you can read my previous post. ARM and Samsung recently uploaded a video providing an overview of big.LITTLE (but instead of IKS and […]
