The Linux Kernel is the center of what makes the Linux and Unix operating systems. The kernel is the foreman or mediator over all your programs and hardware components. As the core of the operating system, the kernel has access to certain services that interact with the systems hardware which no other program has direct access to. If a program wants to carry out a special task, then it must go though the kernel first. When a program wants to run, write data to a disk, write to ce... more...

We have had some time now to get accustomed to Microsoft's latest incarnation of Windows with its release of Vista. And it seems the general consensus is....PASS! If you are considering a new computer, understand the hardware has not caught up to the physical demands set forth by Microsoft and it's newly born cash cow. The most important upgrade you could buy to make your computer experience worthwhile is more memory. In other words, the hardware needs to catch up to the ... more...

This deals with what action is to be taken (during a reboot) after a power failure or an incomplete shutdown of a Linux system due to any reason. This problem seems to be very common since many newcomers install Linux and get all the various softwares/hardwares working under Linux and suddenly one day the power fails. There are a few things that you can try to get Linux back on track.. 1. While rebooting, Linux may print a message saying that there is a problem with the file system and i... more...

Red Hat released its "Core"-less Community Linux distribution, Fedora, now on version 7. You can get the distribution via Bit Torrent, direct download or doing a network install. This is also the first release that comes in different sub-versions or spins, GNOME and KDE desktop environment based bootable live images that can be installed to a hard disk. These spins are meant for desktop users who prefer a single disk installation and for sharing Fedora with friends, family, and e... more...

The OpenMoko-based FIC Neo1973 is "the World's First Integrated Open Source Mobile Communications Platform", the smartphone is expected to compete against the Windows Mobile, Palm, Symbian and now OS X operating systems on mobile phones. Based on the initial specs, it will be released with EDGE, like the iPhone, instead of the faster 3G or HSDPA , I am having doubts if Europe and Asia will find it interesting. Also, Motorola is showcasing their MotoRIZR K6 as a mobile phone ... more...

The official name of the Mozilla Application Suite developed by the Mozilla Foundation. It is also the public and original name but got changed recently to SeaMonkey suite. In informal terms, the name found usage in combination with other phrases related to the now-defunct Netscape Communications Corporation and the various application software that were related to it. The code base for Netscape Communicator Internet suite was given the Netscape Public License, which is a free software or... more...

In spite of several other operating systems gaining a huge monopoly in the market, Linux has always has its own fan following. Even today, many people are realizing the strategic important of Linux as an operating system. There are several reasons for this - the quality is good, security is high and best of all, fixes are quick in a Linux system. More importantly, it is available for use by anyone and everyone who cares to use it because of the source code that's freely available.more...

Nine times out of ten computer problems can be resolved quickly and painlessly if you know what steps to take. As a computer repair technician the most common question I get asked is 'Why is my computer is so slow'. In this article I will talk about how to fix a sluggish computer. Every computer connected to the internet will at one time or another begin to slow down to a crawl if certain maintenance procedures are not followed. What a lot of people don't realize is that ev... more...

How will you react when you come to know you are being watched? Will there be a chill in your spine? Quite possible! But let's look at the same thing in a different way. If you have the premonition that someone is keeping an eye on you, there is a possibility that you can take steps to counter the attack. Am I right? Now wear the same spectacles and watch the spyware through your angle of vision. What do you find out? Spyware was really troublesome when you were not that awar... more...

If you should talk to a tech about Vista, most will tell you to hold off for awhile. Not that there is anything really wrong with Vista, but because there is a severe lack of driver support. Many of the devices you normally use are behind in issuing new compatible drivers. The problem affects many consumers because all the big box stores are only selling Vista loaded machines. It is not uncommon to get your new computer home only to find out printers, scanners, cameras and other accessor... more...

This year brings the long awaited release of Microsoft Vista. I know many of you received new computers or components with a coupon to upgrade. But wait before you run out and put down your money. Vista might not be the best choice for you. Vista is indeed a big step forward, but notice, I say step and not leap. It is the first next generation operating system designed to make full use of all the changes in technology over the last 10 years. Vista is also heading toward the future with some very... more...

Your Windows registry is a tool that is on every computer. The registry is a database that is consistently used by Windows every time you are using your computer. Your operating system must tap into the store of hardware and software configuration that is stored on your registry every time you call for a function. The registry is a key part of your computer and every time that you want your computer to perform an action, it will need to go to the registry information to make sure that happens... more...

The configuration and default parameter data stored in the Windows Registry controls the behavior of Windows and all hosted applications and services. Applications are able to interact directly with the Registry to add, change, or remove this data, and the Registry in turn saves altered application data to the permanent hive files from which it is built, retrieving it when the applications are launched. In this way, the Registry is continuously bombarded with changes made by ap... more...

I heard a funny story the other day that made think there is a real serious problem out there, let me explain, in my job, I meet many different people and when they ask me what I do, I tell them "I'm a computer engineer". Then it all starts, usually something like this: "my pc was running slow, so I put it into a shop, got it back cost me a fortune and 1 month later it's as bad as ever". Here's the thing, how many times have you just needed to print o... more...

Microsoft is is the process of releasing a new operating system called Vista. Windows Vista is suposedly available for businesses and schools to purchase on Nov 30th 2006, but not yet ready for home use. The home version of Vista will be released in January 2007, which makes perfect sense if you think about it. There are two levels of computer recommendations for Windows Vista, those dubbed Vista-Capable and those dubbed Premium-Ready. Microsoft has now revealed the specifics in each... more...

Since I'm going to talk about the Windows registry, it's better to give you a big picture of what it is before delving into the details. Let me put it this way, the registry is a hierarchical database in the Windows operating system, where configuration settings related to hardware, user preferences, memory setup, and applications are stored. You probably won't notice a need to fix any registry problems when your system is new, but as you use Windows for a period of time, your reg... more...

Should you stay clear of something in your computer that stirs up a bunch of hives every time you reboot? The Windows Registry is such a creature, and while it is certainly true that you can't be too cautious when accessing and editing Registry files, there are significant advantages to learning more about them. A general understanding of the Registry and how it works can help you identify and fix many of the problems commonly associated with its degradation, or safely nav... more...

In general, the occurrence of errors in a system's Registry increases over time and with the Registry's continued growth. This is because the most common and abundant errors are orphaned Registry entries created during the installation or incomplete removal of registered applications and hardware drivers, making them largely responsible for the overall degradation of database stability as the Registry is forced to grow around them. These errors usually have a minimal ... more...

The most important reason your should fix Windows Registry errors as they occur is that this the one single preventative measure can greatly increase the life-expectancy of your Windows system by stabilizing the growth of its Registry. Prevention is Key! It is a fact of Windows that trying to fix Registry problems after they occur is much more difficult than preventing their occurrence in the first place. So when it comes to the Windows Registry, the motto should always be "... more...
