Faster Shutdown for XP

How you can make sure that your system shuts down faster. If shutting down XP takes what seems to be an inordinate amount of time, here are a couple of steps you can take to speed up the shutdown process:

Don’t have XP clear your paging file at shutdown. For security reasons, you can have XP clear your paging file (pagefile.sys) of its contents whenever you shut down. Your paging file is used to store temporary files and data, but when your system shuts down, information stays in the file. Some people prefer to have the paging file cleared at shutdown because sensitive information such as unencrypted passwords sometimes ends up in the file. However, clearing the paging file can slow shutdown times significantly, so if extreme security isn’t a high priority, you might not want to clear it. To shut down XP without clearing your paging file, run the Registry Editor (click Start > Run, then type 'regedit' in the Run box) and navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Change the value of ClearPageFileAtShutdown to 0. Close the Registry, and restart your computer. Whenever you turn off XP from now on, the paging file won’t be cleared, and you should be able to shut down more quickly.

Note: Please be careful when editing the Registry; you can do a lot of damage here. Don’t change or delete anything unless you know exactly what it is.

The Origen of Google

key milestones in Google's development:

1996

• Larry and Sergey, now Stanford computer science grad students, begin collaborating on a search engine called BackRub. ( Larry Page and Sergey Brin called their initial search engine "BackRub," now known as Google, named for its analysis of the web's"back links.")
• BackRub operates on Stanford servers for more than a year --eventually taking up too much bandwidth to suit the university so they where asked to take data base out side university and free university bandwirth.
• BackRub is a research project of the Digital Library Project in the Computer Science Department at Stanford University.BackRub was written in Java and Python and runs on several Sun Ultras and Intel Pentiums running Linux. The primary database is kept on an Sun Ultra II with 28GB of disk.

1997

(This is from unoffical source-

-->Sean and Larry were in their office, using the whiteboard,trying to think up a good name - something that related to the indexing of an immense amount of data. Sean verbally suggested the word "googolplex," and Larry responded verbally with the shortened form, "googol" (both words refer to specific large numbers). Sean was seated at his computer terminal, so he executed a search of the Internet domain name registry database to see if the newly suggested name was still available for registration and use. Sean is not an infallible speller, and he made the mistake of searching for the name spelled as "google.com," which he found to be available .

-->This is the doctorate thesis of Sergey Brin and Lawrence Page (the founders of Google.) In it they state:We chose our system name, Google, because it is a common spelling of googol, or 10100 and fits well with our goal of building very large-scale search engines.)

•Larry and Sergey decide that the BackRub search engine needs a new name. After some brainstorming, they go with Google -- a play on the word "googol," a mathematical term for the number represented by the numeral 1 followed by 100 zeros. The use of the term reflects their mission to organize a seemingly infinite amount of information on the web.

1998-August

•Sun co-founder Andy Bechtolsheim writes a check for $100,000 to an entity that doesn't exist yet: a company called Google Inc.Larry and Sergey open a bank account in the newly-established company's name and deposit Andy Bechtolsheim's check and that happen when Bechtolsheim wrote a check in favor of Larry and Sergey and they Saied sir we dont have a bank account so Mr.Bechtolsheim Saied then go and make one and that was the first time he did something like that after seeing there demo of Search engine and its comparison with other SE.

And today Google have taken over and own Youtube, Blogger, Gmail, Google maps, Google News, Google image and viedo search, Picaso any many other.Google is home page of many browser at home and office, in fact it have lancuched its own browser called Google Chrome and compay will lanuched Google operating system in 2010 to run Windows OS out of business may be? Google get millions of hits a day which in turns can be calculated in lacks of $$$$/day.

When to Use FAT or FAT32 File System?

If you're running more than one operating system on a single computer (see Dual booting in Guides), you will definitely need to format some of your volumes as FAT. Any programs or data that need to be accessed by more than one operating system on that computer should be stored on a FAT16 or possibly FAT32 volume. But keep in mind that you have no security for data on a FAT16 or FAT32 volume—any one with access to the computer can read, change, or even delete any file that is stored on a FAT16 or FAT32 partition. In many cases, this is even possible over a network. So do not store sensitive files on drives or partitions formatted with FAT file systems.

What is FAT32 File System?

The FAT32 file system, originally introduced in Windows 95 Service Pack 2, is really just an extension of the original FAT16 file system that provides for a much larger number of clusters per partition. As such, it greatly improves the overall disk utilization when compared to a FAT16 file system. However, FAT32 shares all of the other limitations of FAT16, and adds an important additional limitation—many operating systems that can recognize FAT16 will not work with FAT32—most notably Windows NT, but also Linux and UNIX as well. Now this isn't a problem if you're running FAT32 on a Windows XP computer and sharing your drive out to other computers on your network—they don't need to know (and generally don't really care) what your underlying file system is.

What and Why is FAT16 File system

The FAT16 file system was introduced way back with MS–DOS in 1981, and it's showing its age. It was designed originally to handle files on a floppy drive, and has had minor modifications over the years so it can handle hard disks, and even file names longer than the original limitation of 8.3 characters, but it's still the lowest common denominator. The biggest advantage of FAT16 is that it is compatible across a wide variety of operating systems, including Windows 95/98/Me, OS/2, Linux, and some versions of UNIX. The biggest problem of FAT16 is that it has a fixed maximum number of clusters per partition, so as hard disks get bigger and bigger, the size of each cluster has to get larger. In a 2–GB partition, each cluster is 32 kilobytes, meaning that even the smallest file on the partition will take up 32 KB of space. FAT16 also doesn't support compression, encryption, or advanced security using access control lists.So now we have moved to advanced file system like FAT32 and NTFS.

What is Autorun.inf ? Find out here

Autorun.inf is the primary instruction file associated with the Autorun function. Autorun.inf itself is a simple text-based configuration file that tells the operating system which executable to start, which icon to use, and which additional menu commands to make available. In other words, autorun.inf tells Windows how to deal open the presentation and treat the contents of the CD.

The entire sequence is initiated when the "disk change notifcation" polling discovers a new disk in the CD or DVD ROM drive. Then, if the "Auto insert notification" feature is enabled (it is by default), Windows checks in the new disk's root directory for the existence of an "autorun.inf" file. If found, Windows then reads and follows the specific instructions this file defines. If no autorun.inf file is found, then Windows refers to the new disk by its serial number and executes the default actions associated with the (data or audio) content on the disk.

What Is SEO?

Introduction to Search Engine Optimization

Search Engine Optimization (SEO) is often considered the more technical part of Web marketing. This is true because SEO does help in the promotion of sites and at the same time it requires some technical knowledge – at least familiarity with basic HTML. SEO is sometimes also called SEO copyrighting because most of the techniques that are used to promote sites in search engines deal with text. Generally, SEO can be defined as the activity of optimizing Web pages or whole sites in order to make them more search engine-friendly, thus getting higher positions in search results.

One of the basic truths in SEO is that even if you do all the things that are necessary to do, this does not automatically guarantee you top ratings but if you neglect basic rules, this certainly will not go unnoticed. Also, if you set realistic goals – i.e to get into the top 30 results in Google for a particular keyword, rather than be the number one for 10 keywords in 5 search engines, you will feel happier and more satisfied with your results.

Although SEO helps to increase the traffic to one's site, SEO is not advertising. Of course, you can be included in paid search results for given keywords but basically the idea behind the SEO techniques is to get top placement because your site is relevant to a particular search term, not because you pay.

SEO can be a 30-minute job or a permanent activity. Sometimes it is enough to do some generic SEO in order to get high in search engines – for instance, if you are a leader for rare keywords, then you do not have a lot to do in order to get decent placement. But in most cases, if you really want to be at the top, you need to pay special attention to SEO and devote significant amounts of time and effort to it. Even if you plan to do some basic SEO, it is essential that you understand how search engines work and which items are most important in SEO.
