The Indian IT services sector may see up to five per cent layoffs -- amounting to more than one lakh job cuts -- over the next six months as companies focus more on cost-cutting due to persisting weakness in global demand, experts say.
Companies may reduce workforce in this fiscal, mostly based on stringent performance criteria, experts added.
"We expect the knowledge industry (IT) to see 3-5 per cent non-voluntary exits in the first two quarters of the financial year mainly in senior and middle levels," Deloitte Touche Tohmatsu Senior Director (Management Consultancy Services) P Thiruvengadam said.
Given the fact that more than 22 lakh people work in the IT industry, five per cent non-voluntary exits would mean more than one lakh employees being shown the door by September.
Nasscom estimates more than 22 lakh people were working in the Indian IT-BPO sector in FY2009 (till February), while indirect job creation is estimated at about eight million.
International Management Institute (IMI) Director C S Venkata Ratnam said, "The IT sector is better off but it may see up to 4-5 per cent job losses in the first two quarters of this fiscal."
I got a couple of mails last week asking me for a suitable substitute for Nero.The guy had apparently not uninstalled Nero properly n to avoid the problem he had deleted the nero directory with all its content .Now when he was reinstalling Nero it wasn’t working.I l deal this part of the problem later ,on how to make Nero work again but now the solution to the first part of the problem.,that is SUBSTITUTEFOR NERO.Well I found this amazing software called BURNAWARE
BurnAware Professional is the professional’s choice for quality CD & DVD media duplication and Blu-ray Disc recording. Apart from the standard features, such as data, audio and video burning, BurnAware Professional offers a wide scope of advanced functionality, allowing you to duplicate CDs and DVDs, make exact copies of discs on your hard drive, write to multiple drives simultaneously. Also it is permitted for commercial use.What really attracted me to this software so much are:
1. Its only 14Mb in size and you can perform all cd/dvd writing functions with it.
2. It can burn BLU-RAY Discs
3. It uses comparatyively much lesser memory resources than Nero ,like I am simultaneously writing a Movie DVD while posting in this blog using my 4 year old PC
Here are the links for downloading the software Burnaware professional with premium cd key and unlimited license

the same.
Windows 7 (formerly codenamed Blackcomb and Vienna) will be the next version of Microsoft Windows, an operating system produced by Microsoft Corporation for use on personal computers, including home and business desktops, laptops, tablet PCs, notebooks and media center PCs. Representatives of Microsoft estimated in 2007 that Windows 7 would have a three-year development time frame following the release of its predecessor Windows Vista, but that the release date would ultimately be determined by product quality.
Windows Vista flopped very badly some regarding it as the 'worlds most unstable OS'.Thus a lot is at stake for Microsoft in its new release 'se7en'.Windows 7 does away with most of Vista drawbacks .It can be called the repaired,patched up and compacted form of Vista with not only looks but also substance it has a lot of new features , such as advances in touch, speech, and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors, improved boot performance, and kernel improvements.
A new feature is called Library. Its not a folder or file but is a way to group related files and folders. If you have documents and text files in several locations like different folders on the hard drive, removable flash drive, network folder, etc. You can use a library to see all the files in those locations collectively in one Library. The files will remain in their respective location; the library contains an index to the file or folder.
The User Account Control (UAC) defaults to a moderate level so it does not constantly pop up asking about everything....I know that means decreased security but its up to you whether you want your screen space to be filled up by warning messages.
For people not having the required configuration there is a thing called windows 7 transformation pack which makes using the currently OS feel and look like windows 7.
Download windows 7 Ultimate from this link (you should have a torrent clint like bit torrent or u torrent for downloading this) http://thepiratebay.org/torrent/4835879/Windows_7_Ultimate_x64_build_7077_RC-Escrow
To NTFS or not to NTFS—that is the question. But unlike the deeper questions of life, this one isn't really all that hard to answer. For most users running Windows XP, NTFS is the obvious choice. It's more powerful and offers security advantages not found in the other file systems. But let's go over the differences among the files systems so we're all clear about the choice. There are essentially three different file systems available in Windows XP: FAT16, short for File Allocation Table, FAT32, and NTFS, short for NT File System.
FAT16 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.
FAT32 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.
The Advantages of NTFS The NTFS file system, introduced with first version of Windows NT, is a completely different file system from FAT. It provides for greatly increased security, file–by–file compression, quotas, and even encryption. It is the default file system for new installations of Windows XP, and if you're doing an upgrade from a previous version of Windows, you'll be asked if you want to convert your existing file systems to NTFS. Don't worry. If you've already upgraded to Windows XP and didn't do the conversion then, it's not a problem. You can convert FAT16 or FAT32 volumes to NTFS at any point. Just remember that you can't easily go back to FAT or FAT32 (without reformatting the drive or partition), not that I think you'll want to.
The NTFS file system is generally not compatible with other operating systems installed on the same computer, nor is it available when you've booted a computer from a floppy disk. For this reason, many system administrators, myself included, used to recommend that users format at least a small partition at the beginning of their main hard disk as FAT. This partition provided a place to store emergency recovery tools or special drivers needed for reinstallation, and was a mechanism for digging yourself out of the hole you'd just dug into. But with the enhanced recovery abilities built into Windows XP (more on that in a future column), I don't think it's necessary or desirable to create that initial FAT partition.
When to Use FAT or FAT32 If you're running more than one operating system on a single computer , 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.

If you download many programs and files off the Internet, you've probably encountered ZIP files before. This compression system was a path breaking invention, especially for Web users, because it lets you reduce the overall number of bits and bytes in a file so it can be transmitted faster over slower Internet connections, or take up less space on a disk. Once you download the file, your computer uses a program such as WinZip or Stuffit to expand the file back to its original size. If everything works correctly, the expanded file is identical to the original file before it was compressed.
At first glance, this seems very mysterious. How can you reduce the number of bits and bytes and then add those exact bits and bytes back later? As it turns out, the basic idea behind the process is fairly straightforward. In this article, I am going to tell you about thr basic concept behind this compression technique
Most types of computer files are fairly redundant -- they have the same information listed over and over again. File-compression programs simply get rid of the redundancy. Instead of listing a piece of information over and over again, a file-compression program lists that information once and then refers back to it whenever it appears in the original program.
As an example, let's look at a type of information we're all familiar with: words.
In John F. Kennedy's 1961 inaugural address, he delivered this famous line:
"Ask not what your country can do for you -- ask what you can do for your country."
The quote has 17 words, made up of 61 letters, 16 spaces, one dash and one period. If each letter, space or punctuation mark takes up one unit of memory, we get a total file size of 79 units. To get the file size down, we need to look for redundancies.
Immediately, we notice that:
"ask" appears two times
"what" appears two times
"your" appears two times
"country" appears two times
"can" appears two times
"do" appears two times
"for" appears two times
"you" appears two times
Ignoring the difference between capital and lower-case letters, roughly half of the phrase is redundant. Nine words -- ask, not, what, your, country, can, do, for, you -- give us almost everything we need for the entire quote. To construct the second half of the phrase, we just point to the words in the first half and fill in the spaces and punctuation.
We'll look at how file-compression systems deal with redundancy in more detail in the next section.
Redundancy and Algorithms
Most compression programs use a variation of the LZ adaptive dictionary-based algorithm to shrink files. "LZ" refers to Lempel and Ziv, the algorithm's creators, and "dictionary" refers to the method of cataloging pieces of data.
The system for arranging dictionaries varies, but it could be as simple as a numbered list. When we go through Kennedy's famous words, we pick out the words that are repeated and put them into the numbered index. Then, we simply write the number instead of writing out the whole word.
So, if this is our dictionary:
ask
what
your
country
can
do
for
you
Our sentence now reads:
"1 not 2 3 4 5 6 7 8 -- 1 2 8 5 6 7 3 4"
If you knew the system, you could easily reconstruct the original phrase using only this dictionary and number pattern. This is what the expansion program on your computer does when it expands a downloaded file. You might also have encountered compressed files that open themselves up. To create this sort of file, the programmer includes a simple expansion program with the compressed file. It automatically reconstructs the original file once it's downloaded.
But how much space have we actually saved with this system? "1 not 2 3 4 5 6 7 8 -- 1 2 8 5 6 7 3 4" is certainly shorter than "Ask not what your country can do for you; ask what you can do for your country;" but keep in mind that we need to save the dictionary itself along with the file.
In an actual compression scheme, figuring out the various file requirements would be fairly complicated; but for our purposes, let's go back to the idea that every character and every space takes up one unit of memory. We already saw that the full phrase takes up 79 units. Our compressed sentence (including spaces) takes up 37 units, and the dictionary (words and numbers) also takes up 37 units. This gives us a file size of 74, so we haven't reduced the file size by very much.
But this is only one sentence! You can imagine that if the compression program worked through the rest of Kennedy's speech, it would find these words and others repeated many more times. And, as we'll see in the next section, it would also be rewriting the dictionary to get the most efficient organization possible
Pattern Searching
In our previous example, we picked out all the repeated words and put those in a dictionary. To us, this is the most obvious way to write a dictionary. But a compression program sees it quite differently: It doesn't have any concept of separate words -- it only looks for patterns. And in order to reduce the file size as much as possible, it carefully selects which patterns to include in the dictionary.
If we approach the phrase from this perspective, we end up with a completely different dictionary.
If the compression program scanned Kennedy's phrase, the first redundancy it would come across would be only a couple of letters long. In "ask not what your," there is a repeated pattern of the letter "t" followed by a space -- in "not" and "what." If the compression program wrote this to the dictionary, it could write a "1" every time a "t" were followed by a space. But in this short phrase, this pattern doesn't occur enough to make it a worthwhile entry, so the program would eventually overwrite it.
The next thing the program might notice is "ou," which appears in both "your" and "country." If this were a longer document, writing this pattern to the dictionary could save a lot of space -- "ou" is a fairly common combination in the English language. But as the compression program worked through this sentence, it would quickly discover a better choice for a dictionary entry: Not only is "ou" repeated, but the entire words "your" and "country" are both repeated, and they are actually repeated together, as the phrase "your country." In this case, the program would overwrite the dictionary entry for "ou" with the entry for "your country."
The phrase "can do for" is also repeated, one time followed by "your" and one time followed by "you," giving us a repeated pattern of "can do for you." This lets us write 15 characters (including spaces) with one number value, while "your country" only lets us write 13 characters (with spaces) with one number value, so the program would overwrite the "your country" entry as just "r country," and then write a separate entry for "can do for you." The program proceeds in this way, picking up all repeated bits of information and then calculating which patterns it should write to the dictionary. This ability to rewrite the dictionary is the "adaptive" part of LZ adaptive dictionary-based algorithm. The way a program actually does this is fairly complicated, as you can see by the discussions on.
No matter what specific method you use, this in-depth searching system lets you compress the file much more efficiently than you could by just picking out words. Using the patterns we picked out above, and adding "__" for spaces, we come up with this larger dictionary:
ask__
what__
you
r__country
__can__do__for__you
And this smaller sentence:
"1not__2345__--__12354"
The sentence now takes up 18 units of memory, and our dictionary takes up 41 units. So we've compressed the total file size from 79 units to 59 units! This is just one way of compressing the phrase, and not necessarily the most efficient one. (See if you can find a better way!)
So how good is this system? The file-reduction ratio depends on a number of factors, including file type, file size and compression scheme.
In most languages of the world, certain letters and words often appear together in the same pattern. Because of this high rate of redundancy, text files compress very well. A reduction of 50 percent or more is typical for a good-sized text file. Most programming languages are also very redundant because they use a relatively small collection of commands, which frequently go together in a set pattern. Files that include a lot of unique information, such as graphics or MP3 files, cannot be compressed much with this system because they don't repeat many patterns (more on this in the next section).
If a file has a lot of repeated patterns, the rate of reduction typically increases with file size. You can see this just by looking at our example -- if we had more of Kennedy's speech, we would be able to refer to the patterns in our dictionary more often, and so get more out of each entry's file space. Also, more pervasive patterns might emerge in the longer work, allowing us to create a more efficient dictionary.
This efficiency also depends on the specific algorithm used by the compression program. Some programs are particularly suited to picking up patterns in certain types of files, and so may compress them more succinctly. Others have dictionaries within dictionaries, which might compress efficiently for larger files but not for smaller ones. While all compression programs of this sort work with the same basic idea, there is actually a good deal of variation in the manner of execution. Programmers are always trying to build a better system.
Have you guy ever heard the program call KGB Archiver. A few days ago I downloaded It to my surprise this program to compressed 450mb into 1.5mb. It is one of the best compression softwares in the world
DATA COMPRESSION MAY RESULT IN IRRECOVERABLE DATA CORRUPTION SO IT IS ADVISED TO USE THE SOFTWARE'S ONLY WHEN REQUIRED.THE MORE IS THE REDUCTION IN SIZE MORE ARE THE CHANCES OF ACCIDENTAL DATA LOSS
