Tiny Core Linux Distribution: 10 MB Linux UI Desktop

If you are looking for a small footprint Linux distribution, you may be interested in Tiny Core Liunx. Here’s the description on Tiny Core Linux Website: Tiny Core Linux is a very small (10 MB) minimal Linux GUI Desktop. It is based on Linux 2.6 kernel, Busybox, Tiny X, and Fltk. The core runs entirely in ram and boots very quickly. Also offered are Micro Core, a 6 MB image that is the console based engine of Tiny Core, and Multi Core, which includes Tiny Core, Micro Core, networking tools and an installer. Micro Core contains CLI versions of Tiny Core’s programs allowing the same functionality of Tiny Core’s extensions, only starting with a console based system. It is not a complete desktop nor is all hardware completely supported. It represents only the core needed to boot into a very minimal X desktop typically with wired internet access. Tiny Core […]

Pandaboard Benchmark: Android (Pandroid) vs Linaro Android

Here’s a video with two Pandaboards (powered by TI OMAP 4) running Android. On the right, there’s Google’s Android, built with the gcc 4.4 toolchain provided by Google and the Pandroid kernel. On the left, there is a Linaro build, using Linaro’s gcc 4.5 toolchain and Linaro’s 3.0 kernel for the Panda board. There is a noticeable difference in the time taken by both boards to execute the demo. (Android Linaro being faster). The demo (Benchmark by 0xlab) uses software decode on both boards. They also showcase the Freescale i.MX53 and ST Ericsson Snowball development boards.

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 […]
