OpenZaurus
OpenZaurus is a defunct embedded operating system for the Sharp Zaurus personal mobile tool PDA. History In its original form, the project was a repackaging of the SharpROM, the Zaurus's factory supplied kernel and root filesystem image. In order to make the Zaurus's OS closer to the needs of the developer community, the SharpROM was altered through the use of bugfixes, software additions, and even removals in order to make the package more open. The OpenZaurus project was revamped completely, becoming Debian-based built from source, from the ground up. Due to the change in direction, OpenZaurus became quite similar to other embedded Debian-based distributions, such as Familiar for the iPAQ. OpenZaurus, in its current form, facilitates an easy method for users to build their own custom images. The efforts of Openzaurus, along with other embedded Linux projects, were integrated into the OpenEmbedded Project, which now provides the common framework for these projects. Variants ...

Sharp Zaurus
The Sharp Zaurus is the name of a series of personal digital assistants (PDAs) made by Sharp Corporation. The Zaurus was the most popular PDA during the 1990s in Japan and was based on a proprietary operating system. The first Sharp PDA to use the Linux operating system was the SL-5000D, running the Qtopia-based Embedix Plus. The Linux Documentation Project considers the Zaurus series to be "true Linux PDAs" because their manufacturers install Linux-based operating systems on them by default. The name derives from the common suffix applied to the names of dinosaurs. History In September 1993, Sharp introduced the PI-3000, the first in the Zaurus line of PDAs, as a follow-on to Sharp's earlier Wizard line of PDAs (the Wizard also influenced Apple's Newton). Featuring a black and white LCD screen, handwriting recognition, and optical communication capabilities among its features, the Zaurus soon became one of Sharp's best selling products. The PI-4000, released in 1994, expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ångström Distribution
The Ångström distribution is a defunct Linux distribution for a variety of embedded devices. The distribution is the result of work by developers from the OpenZaurus, OpenEmbedded, and OpenSIMpad projects. The graphical user interfaces (GUIs) available are OPIE and GPE among other options. The Ångström distribution is in "competition" witPoky Linux Ångström is based on the OpenEmbedded project, specifically the OpenEmbedded-Core (OE-Core) layer. While both Ångström and Poky Linux are based on OE-Core, mostly utilize the same toolchain and are both officially "Yocto compatible", only Poky Linux is officially part of the Yocto Project. Ångström primarily differs from Poky Linux in being a binary distribution (like e.g. the Debian, Fedora, OpenSuse or Ubuntu Linux distributions), using opkg for package management. Hence an essential part of Ångström builds is binary package feed allowing to simply install software distributed as opkg packages, without having t ...

OpenEmbedded
OpenEmbedded is a build automation framework and cross-compile environment used to create Linux distributions for embedded devices. The OpenEmbedded framework is developed by the OpenEmbedded community, which was formally established in 2003. OpenEmbedded is the recommended build system of the Yocto Project, which is a Linux Foundation workgroup that assists commercial companies in the development of Linux-based systems for embedded products. The build system is based on BitBake "recipes", which specify how a particular package is built but also include lists of dependencies and source code locations, as well as for instructions on how to install and remove a compiled package. OpenEmbedded tools use these recipes to fetch and patch source code, compile and link binaries, produce binary packages ( ipk, deb, rpm), and create bootable images. Historically, OpenEmbedded's collection of recipes was stored in a single repository, and the metadata was structured in a form now called "O ...

Familiar Linux
Familiar Linux is a discontinued Linux distribution for iPAQ devices and other personal digital assistants (PDAs), intended as a replacement for Windows CE. It can use OPIE or GPE Palmtop Environment as the graphical user interface. Technical details It is loosely based on the Debian ARM distribution, but uses the ipkg package manager. It contained Python and XFree86. History In May 2000, Alexander Guy took a kernel that had been worked on by Compaq programmers, built a complete Linux distribution around it, and released the first version of Familiar (v0.1). The first version was released in May 2000. It was developed as part of the Handhelds.org project. Reception According to a 2004 review by IBM developerWorks, Familiar Linux needed more polish and "could gain mass acceptance if a dual-boot Multi-booting is the act of installing multiple operating systems on a single computer, and being able to choose which one to boot.

Pocket PC
A Pocket PC (P/PC, PPC) is a class of personal digital assistant (PDA) that runs the Windows Mobile or Windows Embedded Compact operating system that has some of the abilities of modern desktop PCs. The name was introduced by Microsoft in 2000 as a rebranding of the Palm-size PC category. Some of these devices also had integrated phone and data capabilities, which were called Pocket PC Phone Edition or simply "Smartphone". As of 2010, thousands of applications existed for handhelds adhering to the Microsoft Pocket PC specification, many of which were freeware. Microsoft-compliant Pocket PCs can be used with many add-ons such as GPS receivers, barcode readers, RFID readers, and cameras. In 2007, with the advent of Windows Mobile 6.0, Microsoft dropped the name Pocket PC in favor of a new naming scheme: * Windows Mobile Classic (formerly Pocket PC): devices without an integrated phone; * Windows Mobile Professional (formerly Pocket PC Phone Edition): devices with an integrated ...

Embedded Systems
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is ''embedded'' as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) used m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bootstrapping
In general, bootstrapping usually refers to a self-starting process that is supposed to continue or grow without external input. Etymology Tall boots may have a tab, loop or handle at the top known as a bootstrap, allowing one to use fingers or a boot hook tool to help pulling the boots on. The saying "to " was already in use during the 19th century as an example of an impossible task. The idiom dates at least to 1834, when it appeared in the ''Workingman's Advocate'': "It is conjectured that Mr. Murphee will now be enabled to hand himself over the Cumberland river or a barn yard fence by the straps of his boots."Jan FreemanBootstraps and Baron Munchausen ''Boston.com'', January 27, 2009 In 1860 it appeared in a comment on philosophy of mind: "The attempt of the mind to analyze itself san effort analogous to one who would lift himself by his own bootstraps." Bootstrap as a metaphor, meaning to better oneself by one's own unaided efforts, was in use in 1922. This metaphor spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
