The Bochs IA-32 Emulator Project unveiled a new version of the popular Bochs emulator to the public today, improving on the stability and ground breaking improvements of Bochs 1.2. Bochs 1.3 includes many major enhancements including a powerful menu-based configuration system and networking support for Linux and Windows NT/2000. Other additions in this release include support for ISO-format disk images, improved mouse performance, physical CD-ROM support for all versions of Windows, parallel port emulation, enhanced debugger, and many cpu and device model improvements. Bochs 1.3 also adds native support for Mac OS X and Amiga MorphOS, along with improved support for BeOS.

The new version of the PHP programming language, PHP 4.1.0, includes several other key improvements: A new input interface for improved security (read below), Highly improved performance in general, Revolutionary performance and stability improvements under Windows. The multithreaded server modules under Windows (ISAPI, Apache, etc.) perform as much as 30 times faster under load! We want to thank Brett Brewer and his team in Microsoft for working with us to improve PHP for Windows. Versioning support for extensions. Right now it's barely being used, but the infrastructure was put in place to support separate version numbers for different extensions. The negative side effect is that loading extensions that were built against old versions of PHP will now result in a crash, instead of in a nice clear message. Make sure you only use extensions built with PHP 4.1.0. Turn-key output compression support. Lots of fixes and new functions.

"Obviously, Kylix OE is not a moneymaker for Borland. It is a gift to the open source community. That community does not even represent Borland's target developer market. Borland customers are, for the most part, programmers and IT shops firmly entrenched in the Windows world. It's aimed at Delphi users who are branching out from writing for the Windows platform to Linux. Not the other way around." Get the rest of the story at LinuxWorld.

In last month's column, Dr. Edward G. Bradford, senior programmer at IBM, covered synchronization primitives and gave a reprise on pipes. This month he takes a first look at communication using sockets. Ed demonstrates some techniques for writing a sockets program and shows how his programming techniques perform in various operating system environments.

With the 2.4 release of Linux come a host of new filesystem possibilities, including Reiserfs, XFS, JFS, and others. These filesystems sound cool, but what exactly can they do, what are they good at, and exactly how do you go about safely using them in a production Linux environment? Daniel Robbins answers these questions by showing you how to set up these new advanced filesystems under Linux 2.4. In this installment, Daniel takes a look at ext3, a new improved version of ext2 with journaling capabilities. Make sure you read the also incredibly interesting previous articles: Parts 1, 2, 3, 4, 5 and 6.

KDE Studio Gold is a full-fledged IDE for the development of sophisticated C++ applications - including the high utility features you expect from a modern development environment, such as code completion, dynamic syntax highlighting and popup function parameter lookup. Debugging is simplified by tight integration with kdbg in the IDE, and comprehensive documentation is provided. Version 3.0 is now available and shipping. TheKompany added a couple of new features to this final release, which includes an integrated Programmers Calculator and Font Viewer. Demo versions are also available.

"Most senior engineers understand the technical details about what it will take to move Linux or FreeBSD or NetBSD or OpenBSD to support enterprise computing environments. What we don't often understand is what the actual competitive advantages of open source systems are, and what the open source communities need to do to help maintain these advantages." The author explains how the two major open source development models work in different ways: the Linux and the *BSD. Read the editorial at BSDToday.

"Nothing determines the peculiar behavior, the feel - even the ultimate success or failure of an operating system - like its virtual memory design." A must-read article for all the Linux coders regarding the problems of the Linux VM so far and the solutions presented recently. Another good reading regarding VMs is an article about the FreeBSD VM, which is known to be one of the best VMs available.

Borland, will announce version 2 of its Kylix package Tuesday. Kylix, introduced in January, lets software developers write programs that can be used on Linux or Windows machines. The new version will add features that improve the product's support for Web services, a representative said. Web services move tasks that took place on a PC or a single server onto a network of servers, ZDNews reports. In other development news, Python 2.2b1 was released.

Following up the interview which OSNews hosted recently regarding modern journaled filesystems, here are two tutorials on how to convert your / (root) Linux partition to SGI's XFS or IBM's JFS filesystems.
