The Contiki Operating System 2.0

The Contiki Operating System 2.0


The Contiki Operating System is mostly known as an operating system for networked embedded systems. more>>
The Contiki Operating System is mostly known as an operating system for networked embedded systems. A few years ago, however, Contikis primary claim to fame was its Commodore 64 port.
With the help of JAC64, a Java-based C64 emulator developed by my colleague and fellow Contiki developer Joakim Eriksson, you can now experience the C64 port of Contiki 1.2-devel1 again, directly in your web browser!
Enhancements:
- Contiki now does dynamic run-time loading and linking of standard ELF files.
- Rime, a protocol stack designed for low-power radio communication, has been added.
- Cooja, a Java-based network simulator for Contiki is included.
- The build system has been reworked to allow for easy cross-compiling for many platforms.
- A new port for the Tmote Sky sensor board has been added.

J Operating System

J Operating System


J Operating System is primarily intended for programmers. more>>
J Operating System is primarily intended for programmers.
Target Users:
- Hobbiests--You used to buy computers to do programming. They didnt do much else. Windows doesnt even come with a compiler, which is ironic since Bill Gates wrote BASIC. The "J" operating system is primarily intended for programmers. Ive attempted to lower the bar, so amateurs can contribute. I hope to recreate the dynamic environment that used to exist when the Commodore 64 was around and everyone was creating odd-ball software.
- Researchers--Im sure many lab researchers still use DOS because they have to interact with hardware, which is difficult with Windows.
Main features:
- No security! You can access all ports, memory and disk blocks to your hearts content. When youre working with your own computer, security just gets in the way and makes things slow--I hate anti-virus and anti-spyware because they just slow things down. When you know you dont have a risk, have no secrets and do regular back-ups, who needs security?
- Uniformity
- There is no virtual memory and everyone is on the same address-map. You can easily communicate between tasks, passing addresses. Addresses start at a base of zero and, essentually, segment registers are not used.
- There is basically one language to learn called "C+" which is a little more than "C", but less than "C++". You dont need to learn a scripting langauge because everything uses this syntax.
- There is an extension of ASCII called "J" rich text which allows colors, links, graphics and various widgets in your documents. This format is used in source code, documents, help, menus, etc.
- Support for compressed, encrypted and contiguous files.
- FAT32, FAT12 and ISO9660 filesystems.
- Blazing-fast compiler which can recompile everything in 5 seconds. It doesnt optimize.
- All source code is included and its still around a Meg.
Hardware:
- PS/2 mouse and keyboard
- VGA graphics
- Some hard drives. Must be on the primary or secondary IDE controller and support LBA28. Drives of 120Gig are the limit.
- Some CD-ROM/DVD drives, including burning.
- Some floppies. Just 1.44Meg and not all types.
- No USB support yet
- No network support yet
- ASCII printers on the parallel port are supported.

Inferno Operating System 20060303

Inferno Operating System 20060303


Inferno is a compact operating system designed for building distributed and networked systems on a wide variety of devices. more>>
Inferno is a compact operating system designed for building distributed and networked systems on a wide variety of devices and platforms.
Inferno was originally developed at Bell Labs (the research division of Lucent Technologies).
Inferno Operating System is a well-designed, economical operating system particularly suitable for use in networked devices such as advanced telephones, hand-held devices, TV set-top boxes, and many other embedded applications.
Inferno can run in native mode on an embedded system or in emulation mode under many different operating systems. Inferno has many features in common with Plan 9.
Cross-Platform Portability
Inferno can run as a user application on top of an existing operating system or as a stand alone operating system. Most of the popular operating systems and processor architectures are supported:
Host Operating Systems:
- Windows NT/2000/XP
- Irix
- Linux
- MacOS X
- FreeBSD
- Solaris
- Plan 9
Supported Architectures:
- Intel x86 (386 & higher)
- Intel XScale
- IBM PowerPC
- ARM StrongARM (ARM & Thumb)
- Sun SPARC
Inferno also runs as a plug-in under Internet Explorer version 4 and higher. Each Inferno system presents an identical environment to the applications, irrespective of the underlying host OS or architecture, allowing the developer to work with a truly homogeneous environment across multiple different platforms.
Portable Applications
Inferno applications are written in Limbo, a modern, safe, modular, concurrent programming language with C-like syntax. It is more powerful than C but considerably easier to understand and debug than C++ or Java. Limbo code is compiled into architecture independent byte code which is then interpreted (or compiled on the fly) on the target processor. This means that any Inferno application will run identically on all Inferno platforms.
Transparent Resources
Inferno offers complete transparency of resources and data using a simple but powerful namespace system. By representing resources as files and having one standard communication protocol, resources such as data stores, services and external devices can easily be shared between Inferno systems. A resource interface may be imported to the local system and used by the applications without them knowing, or needing to know, whether it is local or remote.
Security
High level security is an important part of the Inferno system. By using one standard protocol for all network communication, security can be focused on one point and provided at a system level. Inferno offers full support for authenticated, encrypted connections using a certificate based user identification scheme and variety of algorithms including:
- IDEA, 56 bit DES, 40, 128 and 256 bit RC4 encryption algorithms
- MD4, MD5 and SHA secure hash algorithms
A Complete Solution
Inferno is not only an operating system, it is also a complete development environment, providing all the tools necessary for creating, testing and debugging the applications that run within it.
- Acme IDE: includes editor, shell, advanced pattern matching tools & more
- Fast Compiler: with full syntax and compile time type checking
- Graphical Debugger: with full stack trace for currently executing threads
- Powerful Shell: with sophisticated scripting capabilities
- UNIX like commands: including bind, grep, gzip, mount, ps, tar, yacc...
Enhancements:
- New licence terms (a `dual licence scheme allowing use as Free Software)
- Styx revision based on 9P2000, and consequent changes to Sys
- Authentication changes
- Improved colour graphics support, including compositing
- Scalable fonts using Freetype
- Revamped Tk implementation
- Window management moved out of Tk to a separate window manager in Limbo
- Limbo: exception handling and fixed-point
- Limbo: other possible changes
- Dis VM changes
- More commands and library modules
- Better network service configuration
- /net/dns served by host and native DNS resolver
- Hosted kernels configured from a parts list as for native kernels
- Signed modules
- Internet Explorer plug-in revised and in source form
- Expanded documentation

Amiga Research Operating System 20060207

Amiga Research Operating System 20060207


Amiga Research Operating System (AROS) is a portable and free desktop operating system. more>>
Amiga Research Operating System (AROS) is a portable and free desktop operating system aiming at being compatible with AmigaOS 3.1, while improving on it in many areas. The source code is available under an open source license, which allows anyone to freely improve upon it.

Goals

The goals of the AROS project is it to create an OS which:

1. Is as compatible as possible with AmigaOS 3.1.
2. Can be ported to different kinds of hardware architectures and processors, such as x86, PowerPC, Alpha, Sparc, HPPA and other.
3. Should be binary compatible on Amiga and source compatible on any other hardware.
4. Can run as a standalone version which boots directly from hard disk and as an emulation which opens a window on an existing OS to develop software and run Amiga and native applications at the same time.
5. Improves upon the functionality of AmigaOS.

To reach this goal, we use a number of techniques. First of all, we make heavy use of the Internet. You can participate in our project even if you can write only one single OS function. The most current version of the source is accessible 24 hours per day and patches can be merged into it at any time. A small database with open tasks makes sure work is not duplicated.

History

Some time back in the year 1993, the situation for the Amiga looked somewhat worse than usual and some Amiga fans got together and discussed what should be done to increase the acceptance of our beloved machine. Immediately the main reason for the missing success of the Amiga became clear: it was propagation, or rather the lack thereof. The Amiga should get a more widespread basis to make it more attractive for everyone to use and to develop for. So plans were made to reach this goal. One of the plans was to fix the bugs of the AmigaOS, another was to make it an modern operating system. The AOS project was born.

But exactly what was a bug? And how should the bugs be fixed? What are the features a so-called modern OS must have? And how should they be implemented into the AmigaOS?

Two years later, people were still arguing about this and not even one line of code had been written (or at least no one had ever seen that code). Discussions were still of the pattern where someone stated that "we must have ..." and someone answered "read the old mails" or "this is impossible to do, because ..." which was shortly followed by "youre wrong because ..." and so on.

In the winter of 1995, Aaron Digulla got fed up with this situation and posted an RFC (request for comments) to the AOS mailing list in which I asked what the minimal common ground might be. Several options were given and the conclusion was that almost everyone would like to see an open OS which is compatible to AmigaOS 3.1 (kickstart 40.68) on which further discussions could be based upon to see what is possible and what is not.

So the work began and AROS was born.

KIWI Image System rev435

KIWI Image System rev435


KIWI Image System provides a complete operating system image solution for Linux supported hardware platforms. more>>
KIWI Image System provides a complete operating system image solution for Linux supported hardware platforms as well as for virtualisation systems like Xen Qemu or VMware. The KIWI architecture was designed as a two level system. The first stage, based on a valid software package source, creates a so called physical extend according to the provided image description. The second stage creates from a required physical extend an operating system image. The result of the second stage is called a logical extend or short an image.
A normal installation process is starting from a given installation source and installs single pieces of software until the system is complete. During this process there may be manual user intervention required. However an operating system image represents an already completed installation encapsulated as a file and optionally includes the configuration for a specific task. Such an operating system starts working as soon as the image has been brought to a system storage device no matter if this is a volatile or non volatile storage. The process of creating an image takes place without user interaction.
This means all requirements of the encapsulated system has to be fulfilled before the image is created. According to this the so called image description tree stores all the information needed to create an image.
Main features:
- Distribution independent
- Support for virtualisation systems like Xen
- Support for deploying images over the network
- Support for VMware / Qemu images
- Support for USB-Stick systems
- Support for LiveCD/DVD systems
- Centralized image description based on XML
- Prebuild boot images for SUSE systems
- Prebuild PXE configuration usable with kiwi netboot images
- SUSE Linux on a 128MB flash card.. yes thats possible

Fastdeploy 0.3 Beta

Fastdeploy 0.3 Beta


Fastdeploy is a Web-based system that works with various operating systems automated installer scripting and/or semantics. more>>
Fastdeploy is a Web-based system that works with various operating systems automated installer scripting and/or semantics (e.g., Kickstart, Preseeding, Windows Unattended, etc.) to completely automate the process of installing operating systems and related server software.

The project is designed to work using PXE network booting rather than CD/DVD based solutions so you can fully automate your infrastructure without needlessly burning CDs.

How does it work?

FastDeploy focuses most of its efforts at supporting the automation capabilities inherent with the installer mechanisms available with each operating system. This means we support Kickstart, Preseeding, and the unattended features of Windows. Its highly probable just about any other automated scripting can be supported.

Using a Web-based interface you can choose the options you want to automatically install (e.g., hostname, domain, IP address, server software to install/configure, etc.) then you PXE boot off your network card and the installation process occurs automatically, without user intervention.

Sys::Hostname::Long 1.4

Sys::Hostname::Long 1.4


Sys::Hostname::Long is a Perl module to try every conceivable way to get full hostname. more>>
Sys::Hostname::Long is a Perl module to try every conceivable way to get full hostname.

SYNOPSIS

use Sys::Hostname::Long;
$host_long = hostname_long;

How to get the host full name in perl on multiple operating systems (mac, windows, unix* etc)

DISCUSSION

This is the SECOND release of this code. It has an improved set of tests and improved interfaces - but it is still often failing to get a full host name. This of course is the reason I wrote the module, it is difficult to get full host names accurately on each system. On some systems (eg: Linux) it is dependent on the order of the entries in /etc/hosts.

To make it easier to test I have testall.pl to generate an output list of all methods. Thus even if the logic is incorrect, it may be possible to get the full name.

Attempt via many methods to get the systems full name. The Sys::Hostname class is the best and standard way to get the system hostname. However it is missing the long hostname.

Hyperic SIGAR 1.4

Hyperic SIGAR 1.4


Hyperic SIGAR is a System Information Gatherer and Reporter. more>>
Hyperic SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.
Hyperic developed SIGAR to overcome the lack of portable access to low-level hardware and operating system metrics found in the Java platform. Its now a key component of the Hyperic HQ management platform since it provides HQ with visibility into things that are otherwise impossible to get to through the standard Java API.
Over the last four years of development, weve enhanced SIGAR to support multiple language bindings and operate on more than 10 OS/hardware combinations.
We think other applications would benefit from the type of information SIGAR provides. We also want to create and foster a community of users who will help us push this technology forward and incorporate it into both open source and commercial applications. So we decided to make this technology open source to give others the ability to enhance their applications.
Main features:
- System memory statistics - total, free, shared
- CPU statistics - load averages, user cpu, system cpu
- Process level statistics - process arguments, memory consumption, cpu consumption, credential info, state, environment, open file descriptors
- File system level statistics - local and remote mounted file systems (NTFS, ext, SMB, NFS, etc), capacity, utilization
- Network interface level statistics - all available network interfaces detected and monitored for bytes received/transmitted, packets received/transmitted, collisions, errors, dropped packets
Enhancements:
- Improved performance and efficiency.
- A bug with User Mode Linux VMs where SIGAR acquired incorrect CPU info has been fixed.

File::SmartNL 0.05

File::SmartNL 0.05


File::SmartNL is a slurp text files no matter the New Line (NL) sequence. more>>
File::SmartNL is a slurp text files no matter the New Line (NL) sequence.

SYNOPSIS

#####
# Subroutine Interface
#
use File::SmartNL qw(config fin fout smartnl);

$old_value = config( $option );
$old_value = config( $option => $new_value);
(@all_options) = config( );

$data = smart_nl($data);
$data = fin( $file_name, @options );
$char_count = fout($file_name, $data, @options);

######
# Object Interface
#
use File::SmartNL;

$default_options = File::SmartNL->default(@options);

$old_value = $default_options->config( $option );
$old_value = $default_options->config( $option => $new_value);
(@all_options) = $default_options->config( );

$data = File::SmartNL->smart_nl($data);
$data = File::SmartNL->fin( $file_name, @options );
$char_count = File::SmartNL->fout($file_name, $data, @options);

Generally, if a subroutine will process a list of options, @options, that subroutine will also process an array reference, @options, [@options], or hash reference, %options, {@options}. If a subroutine will process an array reference, @options, [@options], that subroutine will also process a hash reference, %options, {@options}. See the description for a subroutine for details and exceptions.

Different operating systems have different sequences for new-lines. Historically when computers where first being born, one of the mainstays was the teletype. The teletype understood ASCII. The teletype was an automated typewriter that would perform a carriage return when it received an ASCII Carriage Return (CR), 15, character and a new line when it received a Line Feed (LF), 12 character.

After some time came Unix. Unix had a tty driver that had a raw mode that sent data unprocessed to a teletype and a cooked mode that performed all kinds of translations and manipulations. Unix stored data internally using a single NL character at the ends of lines. The tty driver in the cooked mode would translate the New Line (NL) character to a CR,LF sequence. When driving a teletype, the physicall action of performing a carriage return took some time. By always putting the CR before the LF, the teletype would actually still be performing a carriage return when it received the LF and started a line feed.

After some time came DOS. Since the tty driver is actually one of the largest peices of code for UNIX and DOS needed to run in very cramp space, the DOS designers decided, that instead of writing a tailored down tty driver, they would stored a CR,LF in the internal memory. Data internally would be either text data or binary data.

Needless to say, after many years and many operating systems about every conceivable method of storing new lines may be found amoung the various operating systems. This greatly complicates moving files from one operating system to another operating system.

The smart NL methods in this package are designed to take any combination of CR and NL and translate it into the special NL seqeunce used on the site operating system. Thus, by using these methods, the messy problem of moving files between operating systems is mostly hidden in these methods. By using the fin and fout methods, text files may be freely exchanged between operating systems without any other processing.

The one thing not hidden is that the methods need to know if the data is text data or binary data. Normally, the assume the data is text and are overriden by setting the binary option.

Perl 5.6 introduced a built-in smart nl functionality as an IO discipline :crlf. See Programming Perl by Larry Wall, Tom Christiansen and Jon Orwant, page 754, Chapter 29: Functions, open function. For Perl 5.6 or above, the :crlf IO discipline my be preferable over the smart_nl method of this program module.
