Development

Jython 2.2 has been released

By Forrest Cook
August 29, 2007

Jython is a Python language implementation in Java. Jython was originally called JPython, that project was started in 1997 by Jim Hugunin at CNRI. The name was changed to adhere to the original JPython license requirements. Jython has been released under version 2 of the Python Software Foundation license.

[Jython]

The Jython project description states:

Jython is an implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform. It thus allows you to run Python on any Java platform.

the Jython FAQ explains further:

Jython implements the Python programming language on the Java(tm) Platform. It consists of a compiler to compile Python source code down to Java bytecodes which can run directly on a JVM, a set of support libraries which are used by the compiled Java bytecodes, and extra support to make it trivial to use Java packages from within Jython.

On August 23, 2007, Frank Wierzbicki announced Jython version 2.2 on his weblog. "This is the first production release of Jython in nearly six years, and it contains many new features". The Jython News page shows that Jython 2.2 has been in beta test since February, 2007.

Jython 2.2 fully implements the features of Python version 2.2. New capabilities in Jython 2.2 include: new-style classes, Java List integration, a PEP 302 implementation, iterators, generators, __future__ division, support for modern JVMs, a new installer and ssl and non-blocking support for sockets. The changelog file has a more detailed release history.

The Jython project roadmap explains the plans for the future developments. Support for Python 3000 is planned. Jython is a few steps behind Python, which is currently at version 2.5.1.

Jython 2.2 is available for download here. The installation instructions are straightforward. A test install was performed on your author's Ubuntu 6.10 (Edgy Eft) system with the Java 2 Runtime Environment, Standard Edition build 1.5.0_08-b03. The installation went smoothly and some simple Python test programs were executed with no problems. As noted in the FAQ, JPython startup was noticeably slower than regular CPython.

If you need to run Python on a variety of Java-supported platforms, or need to access Java classes under Python, give Jython 2.2 a try.

Virtualization Software

Interview with OpenVZ Project Manager Kir Kolyshkin (MontanaLinux.org)

MontanaLinux.org has an interview with Kir Kolyshkin, project manager for OpenVZ, a Linux virtualization project.

ML: Are there any areas in the OpenVZ project that you wish you had a bunch of volunteers to work on?

Kir: We have already seen some good contributions here and there, but there's always room for more! I would really like people to work more on tools, especially template tools and OpenVZ control libraries (a.k.a. vzctl-lib). A lot of people already contribute OpenVZ templates, and I'd like that to continue with not only OS templates, but also some kind of virtual appliances (i.e. a pre-installed set of applications for a specific purpose, like running a mail server).

I wish we could have some help with the mainstream integration -- if anyone would like to join the fun, start with subscribing to containers-at-linux-foundation-dot-org.

(thanks to Warren Sanders).

Science

p version 2 announced

Stable version 2 of p has been announced. "In p, a bunch of particles interact with each other according to this simple rule: every particle moves towards, away, or watches another particle(s). When the program starts, each particle chooses a random color, position, and the particle(s) it will move towards, away, or watch. As the program runs, some particles join together to form a train and journey together thereafter. Some orbit each other. Some collapse into each other. Some form swarms that split and join. One cannot predict when or where or how many of these behaviours will emerge but they usually do."

GTK support in GAMBAS coming of age ... (GnomeDesktop)

GnomeDesktop looks at new GTK support in GAMBAS, a BASIC language environment. "More recently however I've been experimenting with GAMBAS (it's *not* aimed at writing games) and found that although it sports a Qt front-end and widget set, it's very robust and provides a fantastic IDE approaching the levels of Delphi / VB. One of the new features available in the development version that has thus far been overlooked is full Gtk support!"
