The first thing we wish to discuss is on how to speedup windows 7 boot times. For booting, this operating system uses one core. To lower the boot time you can increase the amount of cores. Don’t understand how to do that? The process is very simple. Click Start and then click ‘run.’ Type ‘msconfig’ in the dialog box. Next click on the tab ‘boot’ and click on ‘advanced options,’ check ‘number of processors’ and enter the number of cores your processor has. Typically, this is 2, 4 or 8. Next, click ‘OK’ and ‘Apply’ and then reboot. You will experience a much faster boot.

For faster performance, you should also remove unwanted fonts out of your computer. There are lots of TrueType fonts which use quite a little bit of system resources. To find the best performance, you have to trim your fonts down. Keep only those fonts that you need to use on a daily basis. To do this, open Control Panel and open fonts folder. Then you need to move those fonts that you don’t have to a temporary directory.

Windows perform Search Indexing so that when you search for any particular file you are able to instantly get it. But when you don’t make use of the search option regularly, then there is no utilization of this Search Indexing feature. Rather, by disabling this feature you are able to increase the performance of the computer. To disable Search Indexing feature just click on Start and type in services.msc, and then find and right-click ‘windows Search.’ Next in the startup type field, choose ‘disabled.’

You may also speedup windows 7 shutdown time just by doing some simple registry change. Click on Start and type in regedit and click Enter. Then, Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl and right-click on waittokillservicetimeout and alter and lower the value. The default value is 12000 (12 seconds) and you will lower this to the number. After completing, click ok and restart pc.

Another very useful strategy is to remove unwanted Startup programs. There are lots of programs start automatically with Windows like Java, Acrobat, Quicktime, and iTunes, etc. How to stop them autostarting? Go to Start and enter ‘msconfig,’ and click on the startup tab and uncheck the programs that you don’t need on startup.

Unix systems have core kernel that is responsible for managing core system operations, such as logical devices for input/output (/dev/pty for example) and allocating resources to user and system services.

Originally designed like a text-processing system, Unix systems share many tools that manipulate and filter text in various ways. In addition, small utilities can be easily combined to form complete applications in rather sophisticated ways. Output from one application can be redirected to some file or any other application. Combining applications with redirects allows creation of simple or more complex scripts which are capable of performing complicated and automated operations on text and files. These applications and scripts are executed from a user shell, which defines the user interface towards the kernel.

Unix is multiprocess, multiuser, and multi-threaded system. This means that more than a single user can execute a shell and applications concurrently, and that each user can execute applications concurrently from within a single shell. Each of those applications can then create and take away lightweight processes as required. Because Unix was created by active developers, rather than operating system administrators, it is best suited to fit programmers needs.

The upcoming Canonical release, which is code-named Karmic Koala, is the latest version of the popular flavor of the Linux OS. The development release on Thursday pushed the OS one step closer to final release, which is due on Oct. 29, according to the company’s release schedule Web page.

An image of the OS is available for download on Ubuntu’s Web site. Test versions of Karmic Koala RC available for download include the server, desktop and netbook versions. The desktop version can also be installed on standard laptops. In testing by IDG News Service, attempts to download the installation file stalled, possibly because of traffic to the server.

Linux could be making headway against Windows in netbooks, which are low-cost mobile devices designed for those who rely on the Web for computing. Canonical has seen some traction in the netbook market, with companies such as Dell offering devices with a customized version of the netbook OS, which is called Ubuntu Netbook Remix. Ubuntu is also competing in the standard PC space with Microsoft’s Windows, which goes on more than 90 percent of computers worldwide.

Beyond Microsoft, Canonical has to battle other Linux distributions such as Intel’s Moblin, which is vying for a place in netbooks and PCs, and Google’s Chrome OS, a netbook OS due for release in the second half of 2010. Many PC makers plan to test Chrome OS with their systems.

Ubuntu 9.10 RC is an upgrade from the previous version, Ubuntu 9.04, which carried the code name Jaunty Jackalope. Built on the latest Linux 2.6.31.1 kernel, Ubuntu 9.10 offers faster boot times, an improved user interface and programming tools for easier software development, according to Canonical. The company is offering different versions of the OS with a variety of graphical desktop environments. The environments integrate everyday applications including instant-messaging software, Web browser, document viewers and multimedia software.

Canonical is offering versions of the OS with a variety of desktop environments, including Gnome, KDE and XFCE. These environments, built on top of the Linux kernel, have unique graphical user interfaces and integrated software.

Karmic Koala includes a new “Ubuntu Software Center” from which users can easily add or remove programs, similar to a feature available in Windows. It improves on an earlier feature for adding and removing programs. The OS also fixes many bugs from previous Ubuntu editions and builds in driver support for more hardware.

Canonical is also offering its online storage and file-sharing service, called Ubuntu One, by default in Ubuntu 9.10. Users can back up, share or sync data with others through the Ubuntu One Web site. The service gives 2GB of online storage free to Ubuntu users, with an additional 50GB costing US$10 a month.

Earlier development of Ubuntu 9.10 releases — including the most recent beta edition — have received mixed reviews on the Web. Some cautioned users to wait until beta testers work out the kinks before installing the OS. Some complained of applications not working, while other disagreed with user interface changes. But some were thrilled by the OS improvements.

“What I have is a remarkably fast and powerful machine built using some inexpensive software and hardware,” wrote a poster going by the name of Liberty in response to a blog entry. Using a test release of Karmic Koala, the poster said setting up an Internet connection on an Intel dual-core Atom system was a breeze. Networking an all-in-one printer was a “piece of cake,” Liberty wrote.
