Red Hat: Xen Not Ready for Prime-Time

A senior Red Hat executive today maintained the Xen open source virtualisation environment was not yet ready for enterprise use, despite "unbelievable" customer demand and the fact rival Novell has already started shipping the software. While rival Novell this month started shipping the software with version 10 of its SUSE Linux Enterprise Server environment, Red Hat continues to have a lack of confidence in the virtualisation newcomer.

Review: Xandros 4 Home Edition Premium

"It's been a while since I looked at Xandros. True to form, it has remained one of the easiest to use and flat out slickest Linux distributions available. This version of Xandros focuses on the 'digital lifestyle' and includes wireless network profiles, a music manager with iPod and MP3 support, photo manager, video players and internet telephone via Skype, among other things. This version also provides good security tools such as a built-in firewall and anti-virus."

Microsoft Recalls Small-Business Product

Microsoft is recalling an update to its Small Business Server product because of a glitch found late in the manufacturing process. They found a problem with Windows Small Business Server 2003 R2 after the product was released to computer makers but before it was made broadly available. "Recently, and during a regular audit as part of our software production process, Microsoft became aware of an issue with the final software containing nonfinal versions of a few core components," Microsoft said in a statement.

Retool Your Linux Skills for Commercial UNIX

Examine how to best migrate your Linux skills to take advantage of AIX and Solaris. Linux is all the rage, but what if you have experience in Linux and need to apply it to a commercial UNIX environment? UNIX and Linux are similar, and many of the same principles exist; there is a shell, root is still all powerful, and many of the tools and applications are the same. This tutorial will show you how to cope and understand the nuances and differences.

Introduction to User Mode Linux; Linux Performance

This chapter provided a summary of the present state of User Mode Linux (UML) and its user community. It contrasts UML with other visualization technologies, and discusses a bit of UML's history and purpose. Also, this chapter covers basic concepts of SCSI over Fibre Channel Protocol (FCP) using raw/block device files and volume managers. In addition, it covers block size, multipath I/O drivers, and striping with a volume manager, and concludes with a discussion of filesystem performance and CPU loading. Examples are included for each topic throughout the chapter.

Understanding Strings and Regular Expressions in C++, C#

Regardless of what type of data you're working with or what kind of application you're creating, you will undoubtedly need to work with strings. No matter how the data is stored, the end user always deals in human-readable text. As such, knowing how to work with strings is part of the essential knowledge that any .NET developer needs to make rich and compelling applications. In addition to showing you how to work with strings in the .NET Framework, this chapter will also introduce you to regular expressions. Also, Jeff Cogswell explains how to use regular expressions to simplify and enhance the power of your programmatic string searching, matching, and replacing.

Should ICANN Open up?

This week, The Register ran a story on how the US supposedly had given up its 'control' over ICANN. ICANN, the body which assigns IP addresses and domain names worldwide, currently falls under the US Commerce Department via a contractual agreement; this means the US government can control ICANN. El Reg claimed the US had given up this control; Ars was quick to respond, stating that "the existing arrangement was likely to continue, at least for another year." Since the US had stated that it wanted to fully privatise ICANN by 2000, we'll have to wait and see what ICANN looks like in a year. In the meantime, do we really want the US to open up ICANN?

5 Ways to Get Vista’s Security Now

"Millions of Windows users run the OS with an administrator account because Microsoft's never made it easy to do anything different. In fact, you have to work a lot harder to run with fewer rights. Microsoft will push Vista as the solution to the ever-increasing number and ingenuity of attacks. But why wait? With our five strategies, you can give Windows XP a taste of Vista's UAC protection."

Open Source and Services

Red Hat's Havoc Pennington wrote a very interesting article on his blog about open source, services and GPLv3. In the piece Havoc argues that sometimes having open and unrestricted services is more important than having the actual source code. He raises the question about how the open source community can move towards a model of open services; he specifically wonders how to finance the associated deployment and maintainance costs. Havoc believes that the GPLv3 fails to address the issue of data access and focuses too much on source access, which he thinks becomes somewhat irrelevant in the growing "software as a service" world.

SymphonyOS: Plea for Help

SymphonyOS, one of the more refreshing Linux distributions, is in trouble, since its lead developer is in financial troubles. "Core symphony development is currently stalled as I am without electricity in my apartment. I need to raise some money this week in order to have electric restored and cover some expenses. Project donations are greatly appreciated and any referral for paying projects are greatly appreciated as well. I have really big plans for symphony in the near future that will hopefully blow some larger distros out of the water. I cant wait to share them all with you."

Fresh Concerns Over Vista Release

Microsoft shares fell on Thursday after it declined to dampen rumours that its new Windows Vista operating system might face fresh delays. Its shares closed down 2% after a Microsoft executive appeared to avoid confirming the current January 2007 Vista release data for consumers. Instead, Microsoft's Kevin Johnson said Vista would be shipped "when it is available".
