How to Run Android Apps in Linux with AndroVM

You may want to run some Android applications in your computer. If you’re using Windows, there’s already a decent option with Bluestacks. If you’re using Linux, you could always install the Android SDK and run the emulator, but I don’t really like this option because of the user interface, and for people who don’t need to use the SDK it’s not really the simplest thing to install. The way to run Android apps in Linux is probably to run an x86 Android virtual machine in VirtualBox. Yesterday, I tried the latest development version of Android x86 4.2, but for some reasons I could not control the mouse, and had to perform all tasks with the keyboard. What I’m going to use today instead is AndroVM, an Android VM for x86 processor, that is even more easy to use than the Android x86 image. The instructions has been performed in a […]

Zopfli Library Improves Zlib Compression by 3 to 8%

Google developers have released a new compression library called Zopfli. This library, written in C, is compatible with zlib, yet provide a better compression, more exactly 3 to 8% according to Google. This library can be used on servers for better compression in order to save bandwidth, as well as delivering web pages faster. Since it’s fully compatible with zlib, the web browsers do not need to be changed. The only drawback is that it’s several magnitude slower than zlib, so it’s better used for static content that is compressed once, and sent over the Internet many times, and it may not be a good choice for dynamic content. The source code is available at https://code.google.com/p/zopfli/, so let’s try it. Get the code and build zopfli:

git clone https://code.google.com/p/zopfli/
cd zopfli
make

git clone https://code.google.com/p/zopfli/

cd zopfli

make

Different levels of compression are available:

./zopfli -h
Usage: zopfli [OPTION]... FILE
  -h    gives this help
  -c    write the result on standard output, instead of disk filename + '.gz'
  -v    verbose mode
  --gzip  output to gzip format (default)
  --deflate  output to deflate format instead of gzip
  --zlib  output to zlib format instead of gzip
  --i5  less compression, but faster
  --i10  less compression, but faster
  --i15  default compression, 15 iterations
  --i25  more compression, but slower
  --i50  more compression, but slower
  --i100  more compression, but slower
  --i250  more compression, but slower
  --i500  more compression, but slower
  --i1000  more compression, but slower

./zopfli -h

Usage: zopfli [OPTION]... FILE

-h gives this help

-c write the result on standard output, instead of disk filename + '.gz'

-v verbose mode

--gzip output to gzip format (default)

--deflate output to deflate format instead of gzip

--zlib output to zlib format instead of gzip

--i5 less compression, but faster

--i10 less compression, but faster

--i15 default compression, 15 iterations

--i25 more compression, but slower

--i50 more compression, but slower

--i100 more compression, but slower

--i250 more compression, but slower

--i500 more compression, but slower

--i1000 more compression, but slower

Linaro 13.02 Release with Linux Kernel 3.8 and Android 4.2.2

Linaro 13.02 is now available, and features Linux Kernel 3.8 and Android 4.2.2. The biggest news this month is probably the first release of a preliminary ARM64 Debian/Ubuntu Raring image. Other noticeable items include work on ARMv7 KVM, more improvements to OpenEmbedded ARMv8 implementation, as well as big.LITTLE MP implementation, and some modifications to the toolchain for Cortex A7 support. Origen images are not available for download this month, and there’s still no ALIP images since they have disappeared since Linaro upgraded to Ubuntu Quantal. Here are the highlights of this release: Android AOSP master build for Galaxy Nexus has been setup All the platforms have been updated to 4.2.2 Support for lava-test-shell has been added to linaro-android-build-tools. Developer Platform CI bring up: ARMv7 KVM – Add Arndale hypervisor patch to u-boot-linaro. CI bring up: Arndale – Add Arndale image reports to LAVA, Enable and verify UEFI support in the […]

Ronetix SAMA5D3x-CM System-on-Modules Powered by Atmel SAMA5D3 eMPUs

Earlier this month, Atmel launched SAMA5D3 Cortex A5 embedded processor family, and Ronetix recently unveiled CPU modules based on the platform. SAMA5D3x-CM are SODIMM SoM based on SAMA5D3 series processor with 512MB DDR2, 256MB NAND Flash, 4MB SPI Flash, and Gigabit Ethernet. The key features of the modules are as follows: MCU – AT91SAMA5D3x series, 536 MHz ARM Cortex-A5 @ 1.2V (SAMA5D31, SAMA5D33, SAMA5D34 or SAMA5D35) System Memory – 512 MB DDR2 SDRAM, 32-bit Storage: 256 MB NAND Flash 16 MB NOR Flash (optional) 4 MiB Atmel SPI Flash One Wire 1024-bits EEPROM and 64-bits ROM Connectivity – 10/100/1000 MBit/s Ethernet Dimensions – 67.6x40mm (SO-DIMM 200 JEDEC MO-274 module) Temperature range – 0° +70°C or -40° to +85° C SAMA5D3-CM boards support Linux 3.6.9 and Android 4.0. Those are actually the modules used in Atmel SAMA5D3 evaluation kits, so Linux and Android support, starter kits, as well as documentation (except […]

$35 expEYES Junior Transforms the Raspberry Pi, Aakash2 Tablet or any Linux Powered Device into an Electronics Lab

I remember in high school in France, our class only had 2 oscilloscopes and few other electronics equipment, needless to say I did not actually get to use an oscilloscope until I went to university. It would have been nice to be able to play around with oscilloscopes, frequency generators, etc… earlier, but due to budget constraints, this was not possible. Dr Ajith Kumar, a scientist working with the Inter University Accelerator Centre of India, has spent several years working on an ultra low cost electronics lab composed of an oscilloscope and a signal generator to provide students attending schools that cannot afford regular equipments. This learning & experimentation tool is called expEYES, and a prototype was demonstrated last year with the Raspberry Pi. At the end of last year, the final version called expEYES Junior (aka expEYES 2.0) was announced, and is now available to schools and hobbyists in […]

Sailfish OS SDK Alpha Release Is Now Available for Linux

Sailfish OS is a new mobile operating system based on the Qt platform that will soon end-up in mobile phone near you. Until now it was possible to build the SDK yourself, but it was pretty challenging since the documentation was lacking, as Jolla, the company behind Sailfish OS, focused on development. The good news is that you don’t need to build the SDK yourself anymore, since Jolla has just released Sailfish SDK Alpha for Linux 32-bit & 64-bit, and Windows & Mac OS versions will come later. You’ll need a computer that meet the following requirements: A host machine running a Linux operating system Oracle’s VirtualBox version 4.1.18 or higher pre-installed on the host machine. About 5GB of free disk space 4GB of RAM or more is recommended You can get started in two steps: Install the SDK – Download the 32 bit or 64 bit Linux installer. (~650 […]

ISEE Introduces IGEP COM CYGNUS & AQUILA Powered by TI Sitara AM335x Processor

ISEE will officially launch and showcase 2 new computers-on-module at Embedded World 2013 on February 26-28, in Nuremberg, Germany: IGEP COM CYGNUS and IGEP COM AQUILA. Both CoM shares the same characteristics except the former is powered by TI Sitara AM3352 (Cortex A8, no GPU) and the later by TI Sitara AM3354 (Cortex A8 + PowerVR GPU). This makes the CYGNUS suited for cost sensitive applications such as industrial control, home automation, and test and measurement devices, and the AQUILA for applications that requires more advanced graphics and multimedia capabilities such as gaming, auto infotainment and navigation devices. The key specifications of the 2 modules are as follows: Processor – Texas instruments Sitara AM3352 Cortex A8 @ 720 Mhz (CYGNUS) and AM3354 Cortex A8 @ 720 Mhz + PowerVR SGX GPU (AQUALIA) System memory – 256 MB DDR3 SDRAM, 303 MHz, 16-bit Storage – 128 MB SLC NAND FLASH + […]
