Free operate software for linux

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.

PowerMail provides a redundant and distributed system for receiving and storing mail.
PowerMail is a redundant and distributed system for receiving mail via SMTP and storing it for users to access with POP. The way PowerMail works is quite unorthodox, and its design emphasizes speed and efficiency.
Modified Maildir mailboxes allow PowerMail to employ hardlinks to save diskspace and deliver messages with thousands of recipients instantly.
PowerMail can operate self-sufficiently or cooperate with a regular MTA to support mail forwarding.
Enhancements:
- fixes for older gcc compilers (Ruben dArco)
- pptool ignored SYSCONFDIR and only did /etc/powermail (Ruben dArco)
- added ldap-forwarding-attribute
- --help display was somewhat screwed (Ruben dArco)
- run-as-uid/run-as-gid broken (Ruben dArco)
- TOP cleaned up (Ruben dArco)

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

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.

ost is a simple yet powerful tool providing mechanisms to automatically audit, maintain and backup systems customizations. ost is particularly well suited to environments where most systems are similarly configured, but will operate just as well if each system is unique.
ost uses at least one of the following two sets of input:
- the systems file catalog if it exists
- user defined "templates" to override the systems catalog
These allow ost to build a virtual image of what the local filesystem is supposed to look like. This image is then compared to the actual state of the local filesystem to obtain the following information about the system:
- List of intact files
- List of modified files
- List of missing files
- List of additional files

mp3cleanup is used to tidy up various aspects of MP3 files, including filenames, ID3 tags, path, m3u playlists, and bitrate.
This is particularly useful for hardware MP3 players that sometimes have arbitrary limitations on the files they work (well) with.
It can operate on single files or on all the files contained in a directory.
Enhancements:
- The -k option was added to check MP3s for bad frames before processing.
- The -D option was added to increase search depth.
- The -b option was added to create DOS format .m3u playlists.
- The -C option was added to copy rather than move.
- The (experimental) -g option was added to set the genre.
- Type "list" or "l" to get a list of genre numbers.
- Support for Ogg Vorbis files was added.
- The default maximum filename length was reduced to 52 chars (for iRiver).
- eyeD3 is used as well as id3tag to set tags, since sometimes tags were left inconsistent.
