Linux Command Line Guides

I’ve found and reshared two interesting graphical resources about the Linux command line via Google+ Linux Community, and I thought I’d also write about it here to reach a wider audience. The first graphic shows which tools to use to monitor or analyze specifics parts that may run in Linux. The command I personally run the most in the list above are iotop for disk write/read throughput, top or htop to check overall and current processes CPU usage, as well as memory usage. Ping is also an all time favorite to check network connectivity. although I sometime use mii-tool, not listed above, to check Ethernet link status. Strace can be very useful to debug binaries, but I don’t use it that often. The next picture, called “Linux Commands Cheat Sheet” is less specific, and can be interesting if you are not familiar with the Linux command line. If the resolution […]

ITEAD Studio IBOX AllWinner A20 mini PC Review

ITEAD Studio IBOX is an AllWinner A20 based mini PC currently running Android or Linux distributions currently featured on Indiegogo. I’ve already written about IBOX in a separate post, where you can get all the specifications, but the company has also sent me a unit (engineering sample) for review. Since the system is still in development, and it’s mostly a development platform, I won’t do a review with video testing, system performance, etc… as usual, but rather show the progress and current issues in terms of hardware and software, and I’ll also mention documentation, and shortly try Android 4.2 (pre-installed) and the Debian 7.0 image released by the company. IBOX Unboxing Pictures I’ve received the device in a cartoon box containing the device itself and a 9V/2A power supply. If you are or become a backer on Indiegogo you’ll also receive an add-on board providing access to a SATA connector, […]

iRobot Ava 500 Telepresence Robot Roams Autonomously, Recharges Itself

Earlier this week, I watched Edward Snowden interview at TED2014 in Vancouver. For obvious reason he was not physically in Canada, but instead used some telepresence robots that could be controlled remotely, and allowed Snowden to move around and see the audience. I thought I may have to look into this type of solutions to write in CNX Spftware, but I eventially did not need to as Linux Gizmos wrote about a similar product called iRobot Ava 500. This robot will automatically learn about its environment, roam the office or factory floor as needed for meetings, and even go back to a docking station to recharge itself when it’s needed. The pictures above show Ava 500 with Cisco Telepresence EX60 solutions that comes with the following specifications: Cisco TelePresence EX60 display 21.5″ LCD (1920 x 1080) 16:9 aspect ratio, 1000:1 contrast ratio 170° viewing angle 5ms response time Cisco TelePresence […]

OpenCL Accelerated SQL Database with ARM Mali GPU Compute Capabilities

We’ve previously seen GPU compute on ARM could improve performance for mobile, automotive and consumer electronics application. GPU compute offload CPU task that can be parallelized to the GPU using APIs such as OpenCL or RenderScript. Most applications that can leverage GPU compute are related to media processing (video decoding, picture processing, audio decoding, image reconigion, etc…), but one thing I did not suspect could be improve is database access. That’s what Tom Gall, Linaro, has achieved in a side project by using OpenCL to accelerate SQLite database operations by around 4 times for a given benchmark. The hardware used was a Samsung Chromebook with an Exynos 5250 SoC featurig a dual core Cortex A15 processor and an ARM Mali T604 GPU. CPU compute is only possible on ARM Mali T6xx and greater, and won’t work on Mali 400 / 450 GPUs. Other GPU vendors such as Vivante and Imagination […]
