"Learn the intricacies of the AIX file system framework. Every operating system provides a native kernel framework that kernel developers have to understand and adhere to when developing a piece of a kernel component for that operating system. This article sheds some light on the AIX file system framework. You need to understand the framework in order to develop a new file system, or to port an existing file system to the AIX operating system."

IBM finally took the wraps off its much anticipated Power6 microprocessor, which company executives said will double the clock speed of its current Power5 chip, without stretching the power envelope. The Power6 processor, unveiled at an event on May 21 in London, is a dual-core chip with a top clock speed of 4.7GHz, double the 2.3GHz of the Power5+ processors. The new chip also includes 8MB of L2 cache - four times as large as the current Power5 offering - and an internal bandwidth of 300GB per second. Ars' John 'Hannibal' Stokes obviously also has his say.

"Today, IBM announced a public beta trial of a virtual Linux environment that will let x86 applications run on its System p Unix servers without modification. The new IBM System p Application Virtual Environment technology will allow x86 binaries to run as well without modification, removing the biggest barrier against effective virtualization for some companies. As a result, customers will be able to consolidate dozens, if not hundreds, of servers into one virtual environment."

IBM is not ready to guarantee that its computer programs are compatible with Oracle's recently launched version of the Linux operating system, an IBM spokesman said on Friday. This means that if IBM software programs turn out to be incompatible with Oracle Enterprise Linux, then it will be up to Oracle - and not IBM - to resolve the issue, said IBM spokesman Matthew McMahon.

In Part 1 of this series you saw how programs on the POWER5 processor work using the 64-bit PowerPC instruction set, then in Part 2 you learned how the PowerPC instruction set addresses memory, and how to do position-independent code. In this article, you learn how to use the very powerful condition and branch instructions available in the PowerPC instruction set.

"When open-source developers and IBM took gambles on each other, free software showed it can flourish in the heartland of corporate computing." This is chapter 7 (free sample, so to speak) of a book on Linux and free software's rise to fame and use in the corporate world.

IBM's Lotus Software division is taking a bigger bite of Apple's Mac OS X. The company on Dec. 28 formally rolled out the latest version of its Lotus messaging software package, dubbed Notes 7.0.2, which will include e-mail, calendar management tools and instant messaging that is specifically designed for Mac OS X users.

Today, IBM's blade servers are available with the company's PowerPC 970 processors. But the Power6 will replace those lower-end sibling in blade servers, Tim Doughtery, IBM's BladeCenter strategist, said in an interview Wednesday. The first Power6 servers are slated for delivery mid-2007, and the Power6 blades will arrive 'close to when we bring Power6 to the market', he added.

This course first presents an overview of what PHP is, how PHP programs run, and why PHP is so popular. You will also see a comparison of PHP to JavaScript, CGI, Net.Data and Java Web applications. Next, you will see how the PHP language is supported on the System IBM i5/OS platform with the Zend Corporation product suite.

"Last week at MPF, IBM unveiled some fresh details of its forthcoming POWER6 server microarchitecture. The company has been fairly stingy with POWER6 information, and most of what was released last week involved the system level. Nonetheless, there were a few interesting tidbits for those of us who are into microprocessors."

This page provides an overview for readers who would like to learn about IBM Systems, but don't know where to start. Get a brief introduction to and history of IBM servers and storage devices, and find out what skills you need to undertake systems development with the wide range of IBM hardware products and related technologies.

The POWER5 processor is a 64-bit workhorse used in a variety of settings. Part 1 of this Assembly language for Power Architecture series is an introduction to assembly language concepts and the PowerPC instruction set. The series as a whole will introduce assembly language in general, specifically language programming for the POWER5.

Lenovo and IBM have announced a battery recall of Sony-made notebook batteries. "Lenovo and IBM Corporation, in cooperation with the U.S. Consumer Product Safety Commission and other regulatory agencies, have announced the voluntary recall of certain lithium-ion batteries manufactured by Sony Corporation. In the interest of public safety, Lenovo will offer customers free-of-charge replacement batteries for all recalled batteries." Apple, Dell, and Toshiba have all also recalled Sony batteries due to fire hazards.

"The OpenPower program offers free remote access to servers running 64-bit Linux on POWER5 processors. In Part 1 of the Taking OpenPower for a spin series, author Peter Seebach introduces the process of getting access to a system and compiling applications for it, both as 32-bit and 64-bit applications. He pays particular attention to issues unique to 'guest' software development without root privileges - something most Linux users have never had to do."
