Linux rarely needs to be rebooted. But when it does, it’s often slow to boot. Fortunately, there are ways to speed things up. Some of these methods are not terribly difficult. (although some, unfortunately, are). Let’s take a look.
1. Disable unnecessary services
Depending upon the use of the machine, plenty of services won’t be needed. Using Linux just for a desktop? Then you won’t need sendmail, httpd, and many other services. If your server is only a Web server, you can shut off many services as well. To do this, you can go to the Administration menu and take a look at the Services entry. Just deselect all of the services you don’t want to start.
2. Disable unnecessary kernel modules
If your desktop is wired to the Ethernet, you don’t need to have a wireless kernel module loaded. This task is a bit more difficult and will require a kernel recompilation, which is not the easiest task to undertake. To do this, you will need the kernel sources. Then, follow the standard steps for compiling a kernel. The difference is that you’re going to go through your system and disable all of the modules you don’t need. Read More»

Jason Did you ever encountered any application or program which runs through command prompt only but does not work when you double click on it, this happens when you launch a program which is a console application. Instead when you try to launch it the command prompt window flashes for a second and closes automatically.
What is a Console Application?
A console application is a computer program designed to be used via a text-only computer interface, such as a text terminal, the command line interface of some operating systems (Unix, DOS, etc.) or the text-based interface included with some Graphical User Interface (GUI) operating systems, such as the Win32 console in Microsoft Windows
Console applications for windows could be some additional commands for windows which you may want to integrate with windows and some other programs which are completely console based or which does not have any GUI interface associated with them. Read More»

Deep inside the bowels of Windows Vista, there’s a secret Administrator account, and it’s different from the normal administrator account you most likely have set up on your PC. This Administrator account is not part of the Administrator group. (Confused yet? You should be.) It’s a kind of superadministrator, akin to the root account in Unix, and by default it’s turned off and hidden. (In describing this hack, we’ll always use the capital “A” for the secret Administrator account, and a lowercase “a” for a normal administrator account.)
In versions of Windows before Windows Vista, the Administrator account wasn’t hidden, and many people used it as their main or only account. This Administrator account had full rights over the computer. Read More»
