Free j gerbomb 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.

Gecode/J is a Java interface for the Gecode C++ constraint programming library. It allows you to:

model and solve
constraint problems in Java.

explore the search tree
with our tree visualization tool. Either using the built-in depth-first search strategy, or manually and interactively. Solutions and choice nodes can be inspected by clicking on them, and visualized using custom actions.

implement propagators
in Java. Whether for prototyping, for teaching, or just for fun. The propagators are integrated fully, so in your model you can mix them freely with the built-in propagators provided by Gecode.

implement branchings
for custom heuristics. Just like propagators, custom branchings fully integrate into Gecode/J.

implement search engines
using copying and recomputation. As search is fully programmable, you can write your own search engine, e.g. for LDS or A* search. In fact, the graphical Gecode.

J-EAI is the first Open Source EAI built as a free software standards-based solution.
J-EAI is built on:
- XML: XML is the new standard for data exchange between heterogeneous systems. It is normalized by the W3C.
- XMPP: XMPP stands for eXtensible Messaging and Presence Protocol. It is standardized by the IETF and is extremely extensible.
Main features:
Cross organisation integration
- J-EAI has been designed to enable applications integration in process that are not limited to the boundary of a single organisation. Its routing mechanism allows several instances of J-EAI managed by different organisation to be interconnected while keeping all the systems independant.
A J-EAI cluster can serve a single domain
- J-EAI works as a cluster to ensure scalability and high-availability. This is an important feature as organisation deploying EAI data bus become highly dependant of the system: high-availability and scalability is thus a must.
Flexible design and extensible data bus
- The J-EAI bus is entirely based on XML and is design as an extensible architecture. This makes it easy to extend and to integrate with legacy application, whatever the technology they are build-in.
Enhancements:
- This version supports collection nodes in the pub sub module.
- Node collection support increases the flexibility of the publish and subscribe model.
- Several bugs have been also fixed.

eMusic/J is an open source download manager for the eMusic.com music service written in Java and aimed at Linux users, although may be easily ported to other platforms.

It takes the .emp file that you get from the eMusic.com website, and downloads the music specified in it. eMusic/J can easily work with Firefox to make downloading songs and albums simple.

QuickFIX is a full-featured open source FIX engine, currently compatible with the FIX 4.0-4.4 spec.
QuickFIX/J runs on Windows, Solaris, Linux, FreeBSD and Mac OS X. APIs are available for C++, Java, .NET, and Python.
The Financial Information eXchange (FIX) Protocol is a "language" which defines specific kinds of electronic messages for communicating securities transactions between two parties.
FIX defines only the format of the messages and the session-level interaction between two applications.
Enhancements:
- This announcement covers both the 1.0.0 release and 1.0.1 maintenance release.
- Features include updated compatibility with QuickFIX C++/JNI, an update to MINA 0.9.x for networking, support for variables in configuration files, performance optimizations in the file message storage plugin, and new file-based message logging options.
- It also includes several bugfixes.
