Today was one of those days when I wished Java would support multiple return values. I had to develop a rather CPU-intensive algorithm which would compute a solution for a knotty constraint problem. Having a solution alone is sometimes not enough and you also need to add some parameters which measure the quality of the computed outcome. Most of these accompanying parameters can or have to be computed within the algorithm itself, but Java allows you to return only one value either an object or a primitive type. People working with Lisp, MATLAB or Perl, just to mention a few, don't have a problem like this at all. Functions supporting multiple return values is already implemented at the language level and frameworks make heavy use of this. But as a Java programmer you are pretty much stuck here and need to consider some other means to come out of this situation. In the following I would like to give some hints on that topic. Hopefully they are of help for anyone having the same problem every now and then.

InfoWorld's Curtis Franklin reviews the four leading contenders to supplant Microsoft Office in business and finds that, while Google Docs is not ready to take on the full mantle, OpenOffice and Zoho provide viable alternatives should IT endeavor to wean business off Office.

InfoWorld's Randall Kennedy has been using a converted Windows Server 2008 as his primary OS since hitting a wall using Vista as a Visual Studio development platform four weeks ago. According to Kennedy, the guerrilla 'Workstation' 2008 OS has turned his Dell notebook into a well-oiled machine that never gets sluggish and rarely needs to reboot. Those interested in making the switch should check out win2008workstation.com, a clearinghouse for 'Workstation' 2008 tips and techniques. Kennedy also offers a link to a Windows 2008 Workstation Converter utility for quick conversion.

Gustav Duarte has written a three part article about the computer boot up process. The series starts with the Motherboard Chipsets and the Memory Map of an Intel computer and then he covers the processes that take place from the BIOS initialization to the boot loader. The final part is the coverage of the Kernel Boot Process.

The ext3undel utility can recover accidently removed data on ext3 filesystems. Users can recover a specific file by name, or they can restore all files marked as deleted. ext3undel is a wrapper for other recovery programs such as Photorec, Foremost and SleuthKit.

A new Ubuntu-based Linux distribution has arrived, aimed at both Linux newbies and content creators. Boasting "out of the box" multimedia codecs, the freely downloadable PC/OS incorporates the lightweight XFCE desktop, and is said to offer a similar layout to the groundbreaking, but ultimately doomed BeOS.
