A Quick Test Drive of Tails, a Privacy Focused Linux Distribution

Tails (The Amnesic Incognito Live System) is a Linux distribution that allows you to use the Internet anonymously and circumvent censorship via the Tor network. It leaves no trace, and is said to use “state-of-the-art” cryptographic tools to encrypt files, emails and instant messages. It’s distributed as a live image that boots from a DVD drive, a USB stick, or an SD card. Tails v1.0 has recently been released. so let’s give it a quick try. Tails is currently only available for x86 (32-bit), no ARM image yet. The source code is available via a git repo. Let’s download the ISO image (mirror), and signature. Alternatively you can download both via BitTorrent. To make sure the image is not compromised it’s recommend to verify the integrity of the ISO image with the signature we’ve just downloaded. You’ll also need a signing key The are several methods, but I’ve opened a terminal, […]

XBMC 13 “Gotham” Released

After month of development, alpha releases, beta releases, RC releases, XBMC 13 “Gotham” is finally out. This is the first official release that supports hardware video decoding for ARM and x86 based Android 4.0+ devices. Support is not available for 100% of devices, as for instance, AllWinner A1X/A20 and Amlogic SoCs do not support the standard Android StrageFright or MediaCodec APIs, but most others should. There’s one XBMC Android version for ARM, one for x86. Android hardware video decoding is obviously not the only feature or improvement brought about by XBMC 13. Here are the key ones: Raspberry Pi and Android speed improvements – Overall system performance improvements, but optimizations are said to be particularly noticeable when opening and browsing libraries, loading images and starting videos. Stereoscopic 3D Rendering – SBS, TAB, anaglyph, and interlaced are supported. XBMC cannot yet support 3D blurays and cannot provide hardware acceleration for FullSBS/TAB […]

Nvidia Tegra K1 CPU/FPU Performance is Comparable to Intel Celeron “Bay Trail-D” J1900 SoC

Nvidia Jetson TK1 development board powered by Nvidia Tegra K1 quad core ARM Cortex A15 processor and a 192-core Kepler GPU has started shipping, and some people have already received theirs, including Michael Larabel (Phoronix) who ran some benchmarks on the board that comes pre-loaded with Ubuntu 14.04 LTS. We already had some benchmarks comparing Tegra K1 to ARM peers on Android, but it’s the first time Linux benchmarks are available. The benchmarks seems to only involve CPU and FPU, and probably not the GPU at this point, but the results are still interesting, and Michael also pointed links comparing Nvidia Tegra K1 development board performance to some Intel Core i5 based PCs, as well as a platform based on an Intel Celeron J1900, a quad core processor part of Bay Trail Desktop family.  The later is most interesting as we compare systems with similar power requirements. Nvidia Tegra K1 […]

HOWCHIP 5420-DVK is a Mobile Development Kit with Samsung Exynos 5420 SoC, an OLED Display

With Arndale Octa already shipping, and the upcoming ODROID-XU2, we already have two low cost boards with Samsung Exynos 5420 big.LITTLE processor for less than $200. But if you want a more complete kit, HOWCHIP 5420-DVK with a 4.65″ OLED display and capacitive touchscreen, 2GB RAM, 4GB eMMC, and various connectors, could be an option. There’s also a Lite version without the OLED display. The board is composed of a CPU module, a baseboard, and a phone like display. Here are the specifications: SoC – Samsung Exynos 5420 Octa with 4x ARM Cortex A15, and 4x ARM Cortex A7 in big.LITTLE configuration, with Mali-T628 GPU. System Memory – 2GB LPDDR3 (POP with CPU) Storage – 4GB eMMC 4GB on board, SD card Slot Video Output HDMI type A connector MIPI DSI header up to 1980×1080 eDP (Embedded Display Port) header up to 2560×1600 Display – 4.65″ OLED (1280×720) with touch […]

How to Mount Google Drive in Linux with google-drive-ocamlfuse

Ubuntu One is not included in the latest Ubuntu 14.04 LTS, and will be phased out on the 1st of July 2014, with files from users being completely wiped out by the 31st of July. I liked the service to exchange files between my Ubuntu computer and Android phones, and features like automatic upload of pictures. Luckily there are alternative such as Dropbox, Copy.com, and ownCloud, each with their own pros and cons. But today, I’ll show how to easily use your Google Drive in Ubuntu / Debian. Last year, I wrote about insync, a beta service that offers Google drive integration into Linux, but since service went out of beta, the company started to charge $15 per account for consumers (one time year), with business plans starting at $15 per year. If you are interested in this solution you can still give it a try for free for 14 […]

Yocto Project 1.6 “Daisy” Released

The Yocto Project Release 1.6 has just been announced. This release is codenamed “Daisy”, and features Poky 11.0.0, which is the reference system used by the project, but other systems could also be used. The Yocto Project is a framework that creates embedded Linux distributions, and is now being used by many Intel and ARM based embedded boards such as Wandboard, Atmel Xplained, Minnowboard MAX, and the Raspberry Pi. Some of the Yocto Project 1.6 features and updates include: Linux kernel 3.14 and 3.10 LTSI eglibc 2.19, gcc 4.8.2 Support for building Python 3 Toaster web UI for exploring build output Documentation – BitBake user’s manual improvment, and added section explaining how to “Write a New Recipe“.

Linaro 14.04 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.04 has been released with Linux Kernel 3.14 (baseline), Linux Kernel 3.10.37 (LSK), and Android 4.4.2. More work has been done on ARMv8 support, and big.LITTLE for both the Linux kernel and Android, as well as work on member hardware platforms such as Origen, Arndale, Arndale Octa, Broadcom Capri, and Hisilicon D01 boards. GCC 4.8-2014.04 Linaro is said to include performance improvements. Linaro Android engineering builds for Nexus 7 and Nexus 10 have been setup, but I can’t quite find the images. They’ve also added the BeagleBone Black to member builds. Here are the highlights of this release: Linaro Stable Kernel (LSK) 3.10.37-2014.04 Updates to Android support (from Google and Linaro) Added Big endian for ARMv7 and ARMv8 Thermal framework DT support Huge pages and transparent huge pages for ARMv8 Tagged pointers for ARMv8 Non-coherent DMA for ARMv8 Other Features big.LITTLE support – ARM MP patch set, IKS (ARMv7 […]
