Free embedded linux software for linux

Alpine is a modular embedded linux distribution for use in small appliances such as VPN gateways, routers, and more.

The name "Alpine" stands for A Linux Powered Integrated Network Engine.
Alpine can boot from floppy/usb/cf/cd/whatever, packages are pulled into RAM, and everything runs from RAM, just like the distros found in LEAF.

This makes for very fast application load times, and provides added security if the boot media is write-protected or removed.

Design Philosophy & Goals

Security comes very high. Everything is compiled with stack smashing protection. It costs approximately 3-5% in speed and size, but we believe its worth it. We also strive to make package configurations secure by default.

Size is also very important. Its why Alpine is an embedded distribution and not a general purpose one. We use uClibc and BusyBox as our main library and shell components. We are however willing to sacrifice some size for speedier development (see below). A typical installation medium would be a small compact flash card, not a floppy.

Innovate, dont Recreate. Our goal is to to keep Alpine as easy to maintain as possible. This means we try to use the work of others as much as possible (obviously only if its open source). By doing this we free up our development time to implement new features and improve the overall product. For example, weve written stripped down shell libraries and re-use the stock Gentoo init.d scripts.

Automation is key. We try to provide automated processes (using scripts) for everything in the build process. Alpine is an extension of the Gentoo build framework. We use scripts that simply convert the Gentoo binary packages. Many things there are similar to Gentoo.

User Friendly. Our goal is to make installation and use of Alpine extremely user friendly without compromising with security. Eventually wed like all packages to be configurable via a sophisticated web interface (webconfs). This is not yet implemented. Wed also like to implement the ability to upgrade packages while maintaining a workable configuration all with minimal impact to the service being upgraded.

Scalable. It should be possible to install Alpine in 3, 300, or 3,000 locations with a similar amount of effort. We plan to write an automated installer, centralized repository manager, centralized configuration manager, and monitoring tools.

Powered by Linux is a KDM theme created after a wallpaper of the same name. It was tested on KDE 3.5.6.

Java Embedded Python embeds CPython in Java. It is safe to use in a heavily threaded environment, it is quite fast and its stability is a main feature and goal.
Main features:
- Using the native Python interpreter may mean a massive speed improvement over Java-based languages.
- Python is mature so authors neednt fear the interpreter will suddenly change widely-used features.
- Access to the high quality Python modules, both native and Python-based.
- Compilers and assorted Python tools are as mature as the language.
- Python is an ideal language for your business logic. It is easy to learn, eminently readable and generally immune to programming gotchas.
Patches, comments and other help is greatly appreciated. If you need help, post to the SourceForge mailing list or forums. Please include code snippets for the most accurate response.

Embedded Slackware is a software development kit for the automated creation of bootable embedded systems based on Slackware and Busybox. The focus is on i486 and ARM systems that use compact flash devices (handhelds and PC104 type boards). The distribution consists of a primary archive with tools, scripts, and documentation, and additional archives for the i486 and PXA250 binary components.
Enhancements:
- This update includes 2.4.34 and 2.6.20 embedded kernels.
- 44 easy-to-use burn scripts and runtime configurations are available.
- The distribution archive is an i486 working subset of the full distribution.
- The complete SDK consists of 5 base archives each for i486, uclibc_i486, pxa255, and uclibc_pxa255 architectures.
- Additional archives are also available for gcc, Wine, and Opie/Pixil LCD desktops.

X-Bone dynamically deploys and manages Internet overlays to reduce their configuration effort and increase network component sharing.
X-Bone discovers, configures, and monitors network resources to create overlays over existing IP networks.
It uses two-layer IP-in-IP tunneled overlays and supports existing applications and unmodified routing, multicast, and DNS services in unmodified operating systems. X-Bone also support IPsec within overlays.
Enhancements:
- This is an integrated distribution of FreeBSD 4.9 with X-Bone 3.2, including utilities and dependencies installed and preconfigured.
