QEMU is an open source emulator for complete PC systems. In addition to emulating a processor, QEMU permits emulation of all necessary subsystems, such as networking and video hardware. It also permits emulation of advanced concepts, such as symmetric multiprocessing systems (up to 255 CPUs) and other processor architectures, such as ARM or PowerPC. This article explores QEMU and its architecture and shows how to emulate a guest operating system on a Linux® host. [...]
Sometimes when you get really lazy you wish someone was there to read things from the computer screen to you. If you have Excel 2007 your wish has come true! Excel will read the cells to you! [...]
Often people are intimidated by the thought of setting up an FTP server on their own. Here are 2 surefire, quick, easy and secure ways of setting up an FTP server in UBUNTU. [...]
You’ve probably come across a document that you’ve written and then emailed to a colleague only to have them email back saying “What’s wrong with the fonts?” They don’t have the fonts that you used in your document. Sure you can search for them and hope the person not only knows how to install them, but has access on their computer to do so. Here is the easy way around that problem. [...]
Everyone knows about the Search box in Firefox and everyone knows that almost every web site has it’s own internal search engine. What would be really cool is if you could use a web site’s internal search engine in your Firefox browser to do a search and return results.

A lot of the time you want to know what is going on with your Linux box when it is booting up. Yeah you can follow the screen, but you don’t catch a lot of the stuff and going through text files is not for me to find out how long a bootup process takes. Here is how you can get a detailed graph of the boot process of your Linux box. [...]
There have been several attempts at Open Source Project Management software including kplato, taskjuggler, planner and OpenWorkBench. All of them have not been able to compete with MS Project. Recently I evaluated Openproj. A new open source Project Management Application. This application has similar features to Microsoft Project, and it can even import native Project files. One major advantage it has over MS Project is that it will run on Linux, Unix, Mac and Windows. [...]
I’m sure that everyone has noticed that every once in a while your hard drive goes berserk and start clicking along like it’s about to die. What has happened is that a background process has taken over your hard drive and is reading or writing intensively forcing it to slow to a crawl. What to do? Follow this guide. [...]
Often when you are browsing Firefox will resize large images by default to fit in the browser window. This can be really annoying if you are browsing something like an image gallery since it has the net effect of forcing you to click extra times. Here is how you change that setting. [...]
Windows uses external hard drives (both USB and FireWire) different than internal drives. The main difference being that write caching is disabled so that you can safely remove the drive at almost any time. This is fine for drives that you routinely remove from the computer and carry around, however if you have an external enclosure that you never disconnect from your computer, this same feature dramatically slows down your drive performance.
