Debian is Worth a Lot (Yet it’s Free) and C/C++ Language Still Rules

James E. Bromberger (JEB) , a contributor to Perl CPAN and Debian, has estimated the cost of developing Debian Wheezy (7.0) from scratch based on the the number of lines of code (LOC) counted with SLOCCount tool, the Constructive Cost Model (COCOMO) and the average wage of a developer of 72,533 USD (using median estimates from Salary.com and PayScale.com for 2011). He found 419,776,604 lines of code in 31 programming languages giving an estimated cost of producing Debian Wheezy in February 2012 of 19 billion US dollar (14.4 Billion Euros), making each package source code (out of the 17,141 packages) worth an average of 1,112,547.56 USD to produce. He also estimated the cost of Linux 3.1.8 Kernel with almost 10 millions lines of source code would be worth 540 million USD at standard complexity, or 1.877 billions USD when rated as ‘complex’. I don’t know which tool he used for […]

Cross-compiling VMWare View for ARM Linux (in Debian/Ubuntu)

Earlier this month, I wrote an article about PCoIP Technology which shows an Android application (VMWare View) running on an OMAP4 Tablet displaying a Windows 7 desktop. This remote desktop technology relies on a powerful server to do the processing and thin clients (in that case Tablets) to display the desktop. Since only pixels are transferred any OS (supported by the server) could be displayed in the thin client. That made me wonder if there was an open source PCoIP client that could run on low end Linux client such as the Raspberry Pi. VMWare View Open Client provides just what we need, but is only available in source code so we need to cross-compile it for ARM or build it in an ARM machine. Today, I’ll show the instructions I followed to cross-compile it for ARM in Debian using Emdebian Toolchain. First download and extract VMware View Open Client […]

Ziilabs Unveils HanZpad Android 4.0 Tablet Reference Design

ZiiLABS, a subsidiary of Creative Technology, has announced the HanZpad platform, a tablet reference design based on ZiiLABS ZMS-40 StemCell Media Processor (4 ARM Cortex A9 cores and 96 GPU cores) optimized for Android 4.x (ICS) and a Chinese operating system. The HanZpad platform is built around Ziilabs ZMS-40 processors with four 1.5GHz ARM Cortex-A9 CPUs and 96-core for the GPU. The ZMS-40 SoC supports H.264 HP decoding of up to 3840×1080 for true 1080p 3D stereo, and 2560×1600 (WQXGA) display resolution support. The firmware can also be upgraded to support for High Efficiency Video Coding (HEVC) aka H.265 which can increase data compression ratio by up to 2 times compared to H.264. Beyond the ZMS-40 processor, the key features of the tablet are as follows: 10.1-inch, 1,280 x 800-pixels IPS panel 1GB memory micro SDHC slot (up to 64GB) Wi-Fi and Bluetooth connectivity 22-hour battery life (~1W power consumption) […]

Wayland Library: X11 Display Server Replacement for Linux

The X Window System has been implemented in Linux since the beginning and manages the graphical user interface of most Linux distributions, although some embedded systems do without X11 and use lightweight graphics libraries such as Nano-X, SDL, DirectFB etc… X11 is invisible to the end-user but does all the hard work needed to have Gnome, KDE and Unity user interfaces work properly and smoothly. However, in recent years, GNU/Linux desktop graphics has moved from having numerous rendering APIs talking to the X server which manages everything towards putting the Linux kernel in the middle with direct rending (e.g. OpenGL, VDPAU/VAAPI) with window systems taking the backstage. This new architecture provides a much-simplified graphics system offering more flexibility and better performance. The problem is that the X Window System is highly complex, a complexity that is not really needed with the newest version of the kernel. That’s where Wayland protocol comes […]

Raspberry Pi Linux Distribution: Raspberry Pi Fedora Remix 14

Several operating systems will be able to run on the Raspberry Pi boards. However, the Raspberry Foundation had announced that they were working with Red Hat to deliver a Fedora release optimized for the board and Broadcom BCM2835 processor (ARMv6 + hard-float support). It appears the full name of this distribution is “Raspberry Pi Fedora Remix 14” most probably based on Fedora 14 (as the name implies), and not the latest Fedora 16 release. This Linux distribution will officially be launched on the 22nd of February 2012 at the Seneca Centre for the Development of Open Technology in Toronto, Canada during a 2-hour event (15:00-17:00) featuring: A hands-on opportunity to use a Raspberry Pi Live demonstrations of the Raspberry Pi Fedora Remix software Examples of the educational uses of the Raspberry Pi The 60-computer build farm used to build the Fedora ARM software on which the remix is based Information […]
