We run a big share of Xen virtual servers spanned over multiple servers and if you want to use the full or best capability of Xen, I would suggest LVM (Logical Volume Manager), it makes life a lot easier, especially for those who do not run a RAID setup (We run RAID10 on all VM nodes) as you can split the partition over multiple hard drives. I’m not going to cover setting up the LVM as there are loads of tutorials on how to do that but I will rather cover the best way to migrate a LVM volume.
Until recently, few enterprises were using open source software for back office applications, such as enterprise resource planning (ERP) and customer relationship management (CRM). But last month, an IDC survey of Western European companies found that nearly ten percent were using open source enterprise software. That's surprisingly high for a market where the industry leaders themselves have only a ten percent share. IDC also reported that the leading open source enterprise applications are growing – by 20 percent or more per year.
One of the newest fads for TV's for Christmas 2007 is 120 Hz (hertz; cycles per second; frames per second). "Everybody knows" that electricity in the U.S. is 60 Hz and many folks know that "regular" TV sets operate at 60 screen refreshes per second so jus
Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as: Finding out bottlenecks. Disk (storage) bottlenecks. CPU and memory bottlenecks. Network bottlenecks.
The truth is, most online readers don’t care much about grammar, spelling and punctuation as long as they get the information they need. With that said, good grammar does build trust in your organization. So does proper spelling — so proofread your text and ask a professional copywriter to look it over if at all possible.
So you have heard of all the advantages and geeky babble about how Linux is better and you have finally decided to try it? Just one thing, you don’t know an awful lot about Linux to get you started. How about some free downloadable ebooks to teach yourself Linux, that you can download today? Would that help? Free – you ask? Yes, free. Welcome to the world of Linux where things are free both as in free speech and also as in free beer (mostly)!
One of the great things about Linux is that there's usually more than one way to do something. Chances are, the way you are doing a particular task right now isn't necessarily the best way either. This collection of hacks is the result of a lot of effort: some are functional, some are fun, but they are all cool! So, start reading, and find out what you could be doing with Linux...
I'm on a quest to build a low-cost 8-core Linux workstation for my new company. I'm using this article to compile all of my research as I scan through the huge amounts of data on the net. Hopefully, someone else will benefit from my work here.
To provide an insight into the quality of software that is available, we have compiled a list of 8 top free Linux compilers. Hopefully, there will be something of interest here for anyone who wants to transform source code into another computer language.
To provide an insight into the quality of software that is available, we have compiled a list of 9 highly polished free Linux IDEs. Hopefully, there will be something of interest here for anyone who wants to quicken the pace of software development
Computer monitoring systems are used to gather data for the purpose of real-time incident notification, performance analysis, and system health verification. Without such a tool, a system administrator would have to login to each machine to collect information on a regular basis. This kind of repetitive task can be automated using a system monitoring tool. System monitoring can also help identify problems before they escalate to emergency status. This type of software is not only useful for network administrators. Home users with a small network or even just a single computer will benefit from advanced notification provided by system monitoring tools. Knowing that free space on the hard disk is running out, or that a particular server/daemon has gone down can be extremely useful.

XRIs are a new kind of identifier on the Internet, similar to URLs or e-mail addresses. However, a single XRI can be used for different services, such as a website, e-mail, skype, icq or any other. They are therefore neither website nor e-mail addresses a
Zenity is a tool that help you to create a common functional GTK dialogs. It have various dialogs that each of them have different ways of presenting data and acquire data from user input. We have introduce how to make use of GUI dialog box in Using GUI dialog box, where we give an example of how zenity create a question dialog box. Besides question dialog box, zenity can create more than that, such as calendar, entry, error, info, file selection, list, notification, progress, warning, scale and text info. In this tutorial, we would like to illustrate how to create every single zenity dialog by examples.
Thirty years ago, Mr. Wallach was one of a small team of computer designers profiled by Tracy Kidder in his Pulitzer Prize winning best seller, “The Soul of a New Machine.”
Bill Weihl, Google's green-energy czar, has been worrying about the environment for much of his IT career, including 10 years teaching computer science at the Massachusetts Institute of Technology and five more as a research scientist at the famed DEC Systems Research Center in Palo Alto, Calif. In 2004, he left Akamai, a content-delivery company where he was chief technology officer, to figure out how he could use his skills to help fight climate change.
One of the many ways KDE makes our lives easier is by providing graphical interfaces for many of the tasks that computer users want to perform. Web browsers typically accept certain protocols that connect them to resources, such as http, https, and ftp. In KDE, these are called KIO slaves, and nearly all KDE applications can interact with them. What makes KDE unique is that there are over 50 KIO slaves available for use. These include everything from basic file management (file:/directoryname) to remote network management (remote:/). I have selected a few notable KIO slaves to demonstrate how they are used and have also included a list of useful ones at the end of this post.
In management science and other applied disciplines, heuristic procedures serve to identify and explore relevant problem aspects, questions, or solution strategies, in distinction to deductive (algorithmic) procedures, which serve to solve problems that a

A social bookmarking web site could change the way you do your job! Bookmarking services store your saved web pages (bookmarks) on a site that you can access from any computer. These services can free you from being tied to the one computer that holds your bookmarks, or favorites, on the browser. No longer will you have to scribble web addresses on notepads or email yourself URLs to remember an interesting site from school to home. Sharing web sites and your thoughts about the sites with colleagues can be accomplished with the click of a button.
Because Today’s Great Ideas start with Yesterday’s Foolish Thinking * Home * Design Portfolio Twittering the Moon: Anyone know what that star is next to the moon? Last night (February 27th 2009) I saw a really bright "star" next to the moon and wondered what it was. I wondered if twitter would tell me, so I did a twitter search for "star next to the moon." Of course, not only did twitter have an answer verified by hundreds of people, but it beautifully illustrated the thoughts of people around the world looking up in wonder at that same bright star in the sky - an age-old philosophical musing suddenly and poignantly jolted into the realm of the tangible. For those of us who still think Twitter is a pointless waste of time, I hope this example provokes some curiosity.
