Automated Linux From Scratch (ALFS) is a project that creates the generic framework for an extendable system builder and package installer.

Why would I want to use ALFS?

After having gone through the LFS and BLFS books more than 2 or 3 times, you will quickly appreciate the ability to automate the task of compiling the software you want for your systems.

What can I do with ALFS?

The goal of ALFS is to automate the process of creating an LFS system. It seeks to make the process of building LFS easier and more efficient while still providing flexibility by granting the user total control and insight into the compilation and management of his LFS build.

How is ALFS implemented?

nALFS

The first ALFS implementation was nALFS by Neven Has. nALFS is a small program written in C. It first parses an XML profile that contains information concerning the LFS build process into a series of internal commands. It can then execute these at your discretion, thus automating the compilation of LFS.

jhalfs

Currently, the official implementation is jhalfs. Originally created by Jeremy Huntwork, but since developed and maintained by Manuel Canales Esparcia and George Boudreau, jhalfs has become a light-weight, practical method of automating an LFS build. jhalfs is a Bash shell script that makes use of Subversion and xsltproc to first download the XML sources of the Linux From Scratch book and then extract any necessary commands, placing them into executable shell scripts. If you do not already have the necessary source packages in place on your system jhalfs can fetch them. Finally, jhalfs generates a Makefile which will control the execution of the shell scripts, allowing for recovery if the build should encounter an error. Since jhalfs extracts its commands to run directly from the LFS book, there are no profiles to edit or maintain.

Note: The 2.2 version of jhalfs has been released. A tarball can been downloaded from http://www.linuxfromscratch.org/alfs/downloads/jhalfs/stable/.

alfs

There are many in-depth features that have been requested for future ALFS implementations. Because of this, development has been slated for an entirely new build tool which will be called alfs. To see a list of features that will appear in alfs, please read our Software Requirements Specification. If you wish to help develop this new tool, please subscribe to the alfs-discuss mailing list and leave a note there explaining your desire to help.

Arianne is a multiplayer online games framework and engine to develop turn based and real time games.

It provides a simple way of creating games on a portable and robust server architecture. The server is coded in Java and uses Python for your game description, provides a MySQL backend and uses an UDP transport channel to communicate with dozens of players.

Our reference client engines are coded using Java and the C language in order to achieve maximum portability.

Arianne has been in development since 1999 and has evolved from a tiny application written in pseudo-C++ to a powerful, expandable but simple server framework, running on the Java platform, and a portable client framework, written in bare C to allow total portability of ariannes clients. Ariannes server is totally client agnostic.

Since the beginning, the key concept at the heart of Ariannes development has been KISS: Keep it simple, stupid!

Arianne games are playable. It now hosts several games:

* a multiplayer Gladiators fighting game
* a multiplayer Pacman game

All our efforts are supported by ariannes server: Marauroa.

Marauroa is completely written in Java using a multithreaded server architecture with a UDP oriented network protocol, a MySQL based persistence engine and a flexible game system. The game system is totally expandable and modifiable by game developers and is able to run Python scripts defining the games rules.

Marauroa is based on a design philosophy we called Action/Perception. Each turn a perception is send to the clients explaining what they currently perceive. Clients can ask the server to perform any action in their name using actions. Marauroa is totally game agnostic and makes very little assumptions about what are you trying to do, allowing a great freedom to create any game type.

Bugs are facts of life, they just happen.

On Arianne we care about code quality so code is fully tested using Test Units with JUnit and cppunit, so all modules are tested for most common cases, allowing a better quality software to be deployed.

The name originated from the Greek name Ariadne. (Latin; Arianna and from French; Arianne). Ariadne is a famous character in Greek mythology. She was the daughter of King Minos of Crete and she was in love with Theseus, the Athenian hero who killed the Minotaur ( a half human, half bull creature).

Theseus married her, however, then later left her alone on the island of Naxos. Ariadne later married Dionisos the God of Wine. The name Ariadne originates from the ancient Greek words ari which means intelligent and adnis which means pure (as in a virgin). Hence, the daughters of the Romans and Greeks where often called by this name.

Linux From Scratch (LFS) is a project that provides you with the steps necessary to build your own custom Linux system.
There are a lot of reasons why somebody would want to install an LFS system. The question most people raise is "why go through all the hassle of manually installing a Linux system from scratch when you can just download an existing distribution?". That is a valid question which I hope to answer for you.
The most important reason for LFSs existence is teaching people how a Linux system works internally. Building an LFS system teaches you about all that makes Linux tick, how things work together, and depend on each other. And most importantly, how to customize it to your own taste and needs.
One of the key benefits of LFS is that you are in control over your system without having to rely on somebody elses Linux implementation. You are in the drivers seat now and are able to dictate every single thing such as the directory layout and boot script setup. You will also know exactly where, why and how programs are installed.
Another benefit of LFS is that you can create a very compact Linux system. When you install a regular distribution, you end up installing a lot of programs you probably would never use. Theyre just sitting there taking up (precious) disk space. Its not hard to get an LFS system installed under 100 MB. Does that still sound like a lot? A few of us have been working on creating a very small embedded LFS system. We installed a system that was just enough to run the Apache web server; total disk space usage was aproximately 8 MB. With further stripping, that can be brought down to 5 MB or less. Try that with a regular distribution.
If we were to compare a Linux distribution with a hamburger you buy at a supermarket or fast-food restaurant, you would end up eating it without knowing precisely what it is you are eating, whereas LFS gives you the ingredients to make a hamburger. This allows you to carefully inspect it, remove unwanted ingredients, and at the same time allow you to add ingredients to enhance the flavour of your hamburger. When you are satisfied with the ingredients, you go on to the next part of putting it together. You now have the chance to make it just the way you like it: broil it, bake it, deep-fry it, barbeque it, or eat it raw.
Another analogy that we can use is that of comparing LFS with a finished house. LFS will give you the skeleton of a house, but its up to you to install plumbing, electrical outlets, kitchen, bathtub, wallpaper, etc.
Another advantage of a custom built Linux system is added security. You will compile the entire system from source, thus allowing you to audit everything, if you wish to do so, and apply all the security patches you want or need to apply. You dont have to wait for somebody else to provide a new binary package that fixes a security hole. Besides, you have no guarantee that the new package actually fixes the problem (adequately). You never truly know whether a security hole is fixed or not unless you do it yourself.
Enhancements:
- The LFS LiveCD Team is proud to announce the release of the x86-6.2-3 version of LFS LiveCD.

The CD is also suitable as a host for building x86 and x86_64 Cross LFS systems. Other features and bugfixes: the CD supports hibernation; the CD file system can be written to; the CD contains a visually pleasing and easy-to-use window manager, XFce...

Erika Educational is a a fully fledged and fully functional real-time operating system (RTOS) for embedded devices.

Erika Educational is a reduced GPL-licensed release of Erika Enterprise: ideal for educational purposes, free software, and available for download at no cost.

Erika Educational should not be seen as a reduced set of Erika Enterprise. Therefore, please do not consider Erika Educational for evaluating the characteristics and performance of Erika Enterprise. While the two originated from the same source code base, Erika Enterprise has been completely redesigned and rewritten to meet industrial needs, whereas Erika Educational have been adapted to 8 bit educational architectures.

Impressions based on Erika Educational should not be applied to Erika Enterprise, as their feature sets are different, and they are, in practice, two different projects, with two different code bases.

yaspi (Yosis Anti-Spam POP3 fIlter bot) is a POP3 mail-scanner specifically made to combat mail bombings caused by viruses (i.e. Swen). It connects to the POP3 server, inspects the messages, and deletes the infected ones by itself automatically without ever downloading them.
yaspi most interesting feature is that it can automatically send abuse reports to the ISPs where the mails were originated. This way, most infected machines will be either disinfected or disconnected from the Internet (and so, sending infected mails!).
Main features:
- its free, distributed under the GNU GPL
- runs under Windows and Unix/Linux (maybe under Mac OS X, but untested)
- virus detecting rules are fully customizable
- integrated with Ricochet to send abuse reports
Enhancements:
- yaspi was killing its own messages, new rule added to let them pass
- new GUI available, still alfa, have several know bugs (but its not going to corrupt your mailbox, I hope!).

ggivnc project is a VNC client using libraries from the GGI project to draw graphics and handle input.

The reason this VNC client came about was to fill the need for a companion to the VNC target in libggi. All existing VNC code was at the time of writing and to the best of my knowledge GPL and originating from the original AT&T code base (either that, or hidden from sight). This VNC client is an implementation from scratch featuring the following encodings:

Raw, CopyRect, RRE, CoRRE, Hextile, Zlib, ZlibHex, ZRLE and LastRect.
