Android Scores Last in Open Governance Index

Vision Mobile recently released a report about different open source projects analyzing their openness via their Open Governance Index. The full report (45-pages) examines: Open source cultural roots and working upstream vs downstream Open source licenses vs governance models Analysis and classification of governance models In-depth reviews of Android, Qt, Symbian, MeeGo, Mozilla, WebKit, Linux and Eclipse Best practices in creating an open source project The governance index is not only based on the percentage of source code that is open, but on the whole software development including the transparency of the decision making-process, the involvement of the community in all aspects of the project, compliance requirements and more. There are a total of 13 metrics accross 4 area of governance: Access: availability of the latest source code, developer support mechanisms, public roadmap, and transparency of decision-making Development: the ability of developers to influence the content and direction of the […]

List of Wireless Standards for Local and Personal Area Networks

While designing your embedded system, you may have to choose between different wireless standards to match your needs. I’ll provide a list a short and mid-range wireless standards, their description and links to open source software stacks (when available) to help you better understand the different options available. Wide Area Network wireless network such as LTE, Wimax, etc.. won’t be discussed in this blog entry. Mesh and IP Networks: Wifi (IEEE 802.11): Wifi is probably the most used wireless standard in consumer electronics devices today as it allows users to connect their device to their LAN wirelessly. An access point has a typical range of about 20 meters indoors and up to 100m outdoors. There are 4 standards 802.11a 802.11b, 802.11g and 802.11n. The latest has a theoretical throughput of 300 Mbps. Check out Wikipedia Wifi page for details. The Wi-Fi stack is part of the Linux kernel but you […]

25 USD ARM11 Linux Computer

The Raspberry Pi Foundation has designed a 25 USD Linux computer prototype for computer education in both the developing and developed worlds. The foundation, a registered British charity, plans to develop, manufacture, and distribute the USB key-sized computer within the next 12 months. Their computer has a USB key form factor and is designed to plug into a TV or be combined with a touch screen for a low-cost tablet. Provisional specifications: 700MHz ARM11 128MB of SDRAM OpenGL ES 2.0 1080p30 H.264 high-profile decode Composite and HDMI video output USB 2.0 SD/MMC/SDIO memory card slot General-purpose I/O Open software (Ubuntu, Iceweasel, KOffice, Python) This device is much cheaper than OLPC XO (target price 100 USD), however, it does not include a keyboard, display nor batteries, so the market is different as it won’t work in places where electricity is unreliable. Watch the video below of David Braben introducing the 25 […]
