ARX – a Mach-like operating system written in Modula-2+[3] developed by Acorn Computers Ltd. ARX is a comprehensive OS going beyond UNIX but backwards compatible is expected to be provided with a layer on top. Lightweight processes, share a common address space, amounts to little more than multiple program pointers with no mutual protection. Obviously this means that switching between such processes (called threads) is extremely fast.

ARX it has written in Modula 2 and is reputed to UNIX like. An interesting point for RISC haters is that the code compiled for the Archimedes is less than twice the size of the same code compiled for the 32016, which is very definately a CISC (Complex Instruction Set .. Computer).

Apparantly Acorn are not releasing details of the ARX operating system because they do not want to “confuse the market”. Even software houses, as a whole, have not been told about ARX. Whilst this may be just because ARX isn’t ready for release yet my paranoid brain worries about it’s price.

It was not finished in time to be used in the Acorn Archimedes range of computers, which shipped in 1987 with an operating system named Arthur, later renamed RISC OS.

Genera – a proprietary, commercial operating system and integrated development environment for Lisp machines created in 1982 by Symbolics. It is a fork of an operating system created on the Massachusetts Institute of Technology (MIT) AI Lab’s Lisp machines which Symbolics had used in common with Lisp Machines, Inc. (LMI), and Texas Instruments (TI).

Symbolics is currently a privately held company which acquired the assets and intellectual property of the old public company called Symbolics, Inc. The old Symbolics was the premier producer of special-purpose computer systems for running and developing state-of-the-art object-oriented programs in Lisp. It designed and built workstations as well as writing a fully object-oriented operating system and development environment called “Genera” to run on those workstations. Symbolics also created a number of software tools to work with Genera. The new Symbolics continues to sell and maintain these products, along with Open Genera which runs on Alpha processor based workstations running Tru64 Unix.

JX – a Java operating system that focuses on a flexible and robust operating system architecture.

The JX system architecture consists of a set of Java components executing on the JX core that is responsible for system initialization, CPU context switching and low-level domain management. The Java code is organized in components which are loaded into domains, verified, and translated to native code.

Main-stream operating systems and traditional microkernels base their protection mechanisms on MMU-provided address space separation. Protection in JX is solely based on the type safety of the intermediate code, the Java bytecode.

The system runs either on off-the-shelf PC hardware (i486, Pentium, and embedded PCs, such as the DIMM-PC) or as a guest system on Linux. Many of the JX Java components, for example the file system, also run on an unmodified JVM. When running on the bare hardware, the system can access IDE disks , 3COM 3C905 NICs, and Matrox G200 video cards. The network code contains IP, TCP, UDP, NFS2 client and server, SUN RPC. Applications that run on top of JX include an Ext2 file system, a window manager, and a database system.

The JX system is developed as an open source system by the University of Erlangen (Friedrich-Alexander-Universität Erlangen-Nürnberg, FAU), a public research university in the cities of Erlangen and Nuremberg in Bavaria, Germany.

VeraCrypt RescueDisk – a live CD disk which features the VeraCrypt encryption software and lets you boot your computer to repair it.

VeraCrypt is a free open source disk encryption with strong security software for the Paranoid brought to you by IDRIX and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt.

VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.

During the process of preparing the encryption of a system partition/drive, VeraCrypt requires that you create a so-called VeraCrypt Rescue Disk (USB disk in EFI boot mode, CD/DVD in MBR legacy boot mode).

If the VeraCrypt Boot Loader screen does not appear after you start your computer (or if Windows does not boot), the VeraCrypt Boot Loader may be damaged. The VeraCrypt Rescue Disk allows you restore it and thus to regain access to your encrypted system and data (however, note that you will still have to enter the correct password then). For EFI boot mode, select Restore VeraCrypt loader binaries to system disk in the Rescue Disk screen. For MBR legacy boot mode, select instead Repair Options.

JavaOS – a closed source, based on a Java virtual machine, and written in Java operating system developed by Sun Microsystems. JavaOS is a highly compact operating system designed to run Java applications directly on microprocessors in anything from net computers to pagers.

JavaOS brings the design advantages of the Java™ programming language to an operating system. As perhaps the smallest and fastest OS that runs Java, JavaOS enables Java on a broad range of devices. JavaOS will run equally well on a network computer, a PDA, a printer, a game machine, cellular telephone, or countless other devices that require a very compact OS and the ability to run Java.

In addition, JavaOS has been built to be fully ROMable for embedded applications, and can run with as little as 512K ROM and 256K RAM. For network computers, an entire system with JavaOS, the HotJava™ Browser and space for downloading Web content and applets requires only 3MB ROM and 4MB RAM. JavaOS can be this small because it is almost completely written in Java.

JavaSoft, headquartered in Cupertino, CA, is an operating company of Sun Microsystems Inc. The company’s mission is to develop, market and support the Java technology and products based on it. Java supports networked applications and enables developers to write applications once that will run on any machine. JavaSoft develops applications, tools and systems platforms to further enhance Java as the programming standard for complex networks such as the Internet and corporate intranets.

LOCUS – a UNIX-like distributed operating system developed at UCLA (University of California, Los Angeles, USA) between 1980 and 1983.

LOCUS is a distributed operating system which supports transparent access to data through a network wide filesystem, permits automatic replication of storaget supports transparent distributed process execution, supplies a number of high reliability functions such as nested transactions, and is upward compatible with Unix. Partitioned operation of subnetl and their dynamic merge is also supported.
The system has been operational for about two years at UCLA and extensive experience in its use has been obtained.

LOCUS is a Unix compatible, distributed operating system in operational use at UCLA on a set of 17 Vax/750’s connected by a standard Ethernets. The system supports a very high degree of network transparency, i.e. it makes the network of machines appear to users and programs as a single computer;
machine boundaries are completely hidden during normal operation. Both files and programs can be moved dynamically with no effect on naming or correct operation. Remote resources are accessed in the same manner as local ones. Processes can be created locally and remotely in the same manner, and process interaction is the same, independent of location. Many of these functions operate transparently even across heterogeneous cpus.

LOCUS also provides a number of high reliability facilities, including flexible and automatic replication of storage at a file level, a full implementation of nested transactions[MEUL 83], and a substantially more robust data storage facility than conventional Unix systems. All of the functions reported here have been implemented, and most are in routine use.

An important part of the LOCUS research concerns recovery from failures of parts of the system, including partition of a LOCUS system into separated but functioning subnetworks.
