Google Goes Funny Again! Falls Intentionally In Recursion
Google never fails to entertain us. This time when you search for Recursion on Google, it keeps on running spell check and displays Did you mean: recursion again and again.
Recursion is the term usually used in Computer Science and this word generally means – to have a activity again and again, forever because the activity itself consist of same activity. It is like two mirrors facing each other and displaying infinite trail of opposite images.
In recursion, the objects are repeated for infinite times. The iteration runs forever. Google displays this quality when you search for recursion.
Despite of clicking on recursion from spell checker – Did you mean, Google will keep on displaying it. Though the spelling is right, Google keeps on telling it again and again.

EASTER EGGS
What are Easter eggs ? You mite probably answer “ they are huge sugar laced eggs filled with chocolates or sweets that would be hidden by elders as a surprise during Easter time”
However in technical jargon ‘Easter eggs is something different .Wikipedia now defines it in this way “An Easter egg is an unintentional hidden message joke or a feature in a object movie ,book cd,dvd web page or a computer program”
Well c the last word of the above paragraph’ computer program’ .Yeah that inspired me to do a bit of research in Easter eggs hidden in computer programs .Most people think of computer engineers as serious geeks for whom Windows is even more important than well eh… wife(sorry bad joke).Nah all of them are not like that ..at least I am not like that..Well getting back to the point many coders have put great jokes up there sleeves into their programs ..its now for us to discover them..
The first easter egg I found was present in Windows 97 .if u type “Bill Clinton” and press Shift+F7 an UK Thesaurus dialogue box comes upon screen with a synonym “I would like to see her naked” .This was at the height of Monica Lewinsky scandal. To get this joke you must set your language setting in Word 97 to UK English.
Here is another one that works in almost every version of Word. Just type “=rand(5,10)” and press enter .You l get 10 paragraphs with 5 sentences each
Open word and type anything anything.Now select whatever you hav written and press control alt-+ and see the cursor change
There are a lot of easter eggs hidden in the web Browser Mozilla Firefox too .lets see some of them type in ‘about:mozilla’ and just see the magic
Or type in ‘about:robots’ and hold
or type 'about: : rights' n see for yourself
Did you know that the flight number of the plane that had hit WTC ...on
9/11 was Q33N ....Open your Notepad in
number i.e Q33N... Increase the Font Size to 72, Change the Font to
Wingdings. U will be amazed by the findings.
Here is a cool notepad secret type “Bush hid the facts “ in a notepad file and save it .then re-open it Whew!!where has the text gone
There are many other Easter eggs in other program .for example you can cheat and win in solitaire by pressing simultaneously Alt- Shift and 2 .
However one of the best is this one .navigate to www.yahoo.com. Make sure the speakers re on .Click on the dot under the exclamation mark of the mast head of Yahoo! .Enjoy
if you find any more such hidden tricks don forget to add in the comments sections
CD VS DVD
Have you ever wondered how does a combo drive play both cd and dvds .?
Why do combo drives often stop reading DVDs but are still able to read CDs?
First lets figure out the essential differnces between CD/ DVDs
DVDs can store more data than CDs for a few reasons:
- Higher-density data storage
- Less overhead, more area
- Multi-layer storage
Single-sided, single-layer DVDs can store about seven times more data than CDs. A large part of this increase comes from the pits and tracks being smaller on DVDs. Let's try to get an idea of how much more data can be stored due to the physically tighter spacing of pits on a DVD. The track pitch on a DVD is 2.16 times smaller, and the minimum pit length for a single-layer DVD is 2.08 times smaller than on a CD. By multiplying these two numbers, we find that there is room for about 4.5 times as many pits on a DVD. So where does the rest of the increase come from?
More Area
On a CD, there is a lot of extra information encoded on the disc to allow for error correction -- this information is really just a repetition of information that is already on the disc. The error correction scheme that a CD uses is quite old and inefficient compared to the method used on DVDs. The DVD format doesn't waste as much space on error correction, enabling it to store much more real information. Another way that DVDs achieve higher capacity is by encoding data onto a slightly larger area of the disc than is done on a CD.
Multiple-Layered Storage
To increase the storage capacity even more, a DVD can have up to four layers, two on each side. The laser that reads the disc can actually focus on the second layer through the first layer. Here is a list of the capacities of different forms of DVDs:
COMBO DRIVES
Every CD/DVD ROM has a lens which is used for reading Data.In case of combo Drive
The same read head lens is used to read both CD's and DVD's
There are two essential physical differences between CD and DVD disc.
First, the smallest DVD pits are only 0.44 micron in diameter; the equivalent CD pits are nearly twice as large, or 0.83 micron wide.
And DVD data tracks are only 0.74 micron apart, wherea 1.6 microns separate CD data tracks. So although a DVD is the same size as a CD,its data spiral is upward of 11 kilometers long-more than twice the length of a CD's data spiral.
To read the smaller pits, a DVD player's readout beam must achieve finer focus than a CD player's does. In order to do this, it uses a read semiconductor laser that has a wave length of 635 to 650 nanometer. In contrast, CD players use infrared laser with a longer wavelength of 780 nanometer. Also, DVD players employ a more powerful focusing lens-one having a higher numerical aperture than the lens in a CD player
In that case after a particular time if the lens weakens only CD's are read and not DVD's.
OPEN SOURCE SOFTWARES
Most software that you buy or download only comes in the compiled ready-to-run version. Compiled means that the actual program code that the developer created, known as the source code, has run through a special program called a compiler that translates the source code into a form that the computer can understand. It is extremely difficult to modify the compiled version of most applications and nearly impossible to see exactly how the developer created different parts of the program. Most commercial software manufacturers see this as an advantage that keeps other companies from copying their code and using it in a competing product. It also gives them control over the quality and features found in a particular product.
Open source software is at the opposite end of the spectrum. The source code is included with the compiled version and modification or customization is actually encouraged. The software developers who support the open source concept believe that by allowing anyone who's interested to modify the source code, the application will be more useful and error-free over the long term.
To be considered as open source software by the software development industry, certain criteria must be met:
- The program must be freely distributed (It can be part of a package that is sold though, such as Red Hat has done with Linux in the example below).
- Source code must be included.
- Anyone must be allowed to modify the source code.
- Modified versions can be redistributed.
- The license must not require the exclusion of other software or interfere with the operation of other software.
Let's take a look at a real world example of open source software. In 1991, Linus Torvalds, a student at the
A common concern for end-users who wish to use open source software is the lack of a warranty and technical support. Because the software's license encourages modification and customization, it is nearly impossible to support. This is why Red Hat Software, founded in 1994, created the "Official Red Hat Linux" and is able to sell this normally "free" software. The main value that Red Hat adds to the package is a warranty and technical support. For most businesses, the assurance of technical support has been a key factor in the decision to buy Linux instead of simply downloading it for free. In addition to Red Hat, there are several other companies that have packaged Linux, usually with additional software, for resale.
Besides Linux, Mozilla (Netscape browser core), Apache (Web server), PERL (Web scripting language) and PNG (graphics file format) are all examples of very popular software that is based on open source.

NTFS VS FAT
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.

FILE COMPRESSION
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:
|
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:
|
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.

CLOUD COMPUTING
CLOUD COMPUTING
Cloud computing can be called a service, a platform, and even an operating system. Some even link it to such concepts as grid computing -- which is a way of taking many different computers and linking them together to form one very big computer.
A basic definition of cloud computing is the use of the Internet for the tasks you perform on your computer. The "cloud" represents the Internet.
Cloud Computing is a Service
The simplest thing that a computer does is allow us to store and retrieve information. We can store our family photographs, our favorite songs, or even save movies on it. This is also the most basic service offered by cloud computing.
Flicker is a great example of cloud computing as a service. While Flickr started with an emphasis on sharing photos and images, it has emerged as a great place to store those images. In many ways, it is superior to storing the images on your computer.
First, Flickr allows you to easily access your images no matter where you are or what type of device you are using. While you might upload the photos of your vacation to
Second, Flickr lets you share the images. There's no need to burn them to a compact disc or save them on a flash drive. You can just send someone your Flickr address.
Third, Flickr provides data security. If you keep your photos on your local computer, what happens if your hard drive crashes? You'd better hope you backed them up to a CD or a flash drive! By uploading the images to Flickr, you are providing yourself with data security by creating a backup on the web. And while it is always best to keep a local copy -- either on your computer, a compact disc or a flash drive -- the truth is that you are far more likely to lose the images you store locally than Flickr is of losing your images.
This is also where grid computing comes into play. Beyond just being used as a place to store and share information, cloud computing can be used to manipulate information. For example, instead of using a local database, businesses could rent CPU time on a web-based database.
The downside? It is not all clear skies and violin music. The major drawback to using cloud computing as a service is that it requires an Internet connection. So, while there are many benefits, you'll lose them off if you are cut off from the Web.
Cloud Computing is a Platform
The web is the operating system of the future. While not exactly true -- we'll always need a local operating system -- this popular saying really means that the web is the next great platform.
What's a platform? It is the basic structure on which applications stand. In other words, it is what runs our apps. Windows is a platform. The Mac OS is a platform. But a platform doesn't have to be an operating system. Java is a platform even though it is not an operating system.
Through cloud computing, the web is becoming a platform. With trends such as Office 2.0, we are seeing more and more applications that were once the province of desktop computers being converted into web applications. Word processors like Buzzword and office suites like Google Docs are slowly becoming as functional as their desktop counterparts and could easily replace software such as Microsoft Office in many homes or small offices.
But cloud computing transcends Office 2.0 to deliver applications of all shapes and sizes from web mashups to Facebook applications to web-based massively multiplayer online role-playing games. With new technologies that help web applications store some information locally -- which allows an online word processor to be used offline as well -- and a new browser called Chrome to push the envelope, Google is a major player in turning cloud computing into a platform.
Cloud Computing and Interoperability
A major barrier to cloud computing is the interoperability of applications. While it is possible to insert an Adobe Acrobat file into a Microsoft Word document, things get a little bit stickier when we talk about web-based applications.
This is where some of the most attractive elements to cloud computing -- storing the information on the web and allowing the web to do most of the 'computing' -- becomes a barrier to getting things done. While we might one day be able to insert our Google Docs word processor document into our Google Docs spreadsheet, things are a little stickier when it comes to inserting a Buzzword document into our Google Docs spreadsheet.
Ignoring for a moment that Google probably doesn't want you to have the ability to insert a competitor's document into their spreadsheet, this creates a ton of data security issues. So not only would we need a standard for web 'documents' to become web 'objects' capable of being generically inserted into any other web document, we'll also need a system to maintain a certain level of security when it comes to this type of data sharing.
Possible? Certainly, but it isn't anything that will happen overnight.
What is Cloud Computing?
This brings us back to the initial question. What is cloud computing? It is the process of taking the services and tasks performed by our computers and bringing them to the web.
What does this mean to us?
With the "cloud" doing most of the work, this frees us up to access the "cloud" however we choose. It could be a super-charged desktop PC designed for high-end gaming, or a "thin client" laptop running the Linux operating system with an 8 gig flash drive instead of a conventional hard drive, or even an iPhone or a Blackberry.
We can also get at the same information and perform the same tasks whether we are at work, at home, or even a friend's house. Not that you would want to take a break between rounds of Texas Hold'em to do some work for the office -- but the prospect of being able to do it is pretty cool.

CREATE ICONS WITHOUT NAMES
I had posted an article few days ago on filenames & I had got a cool comment from one of my friend. I had challenged him to try an create a folder named ‘con’…and here was the reply
"
Now lets analyze what is happening here when alt+255 is pressed a blank space character is created so the name of the file becomes ”(space)con” instead of “con” so u can rename it as ‘con’
..First question .
Why cant you rename a file a ‘con’ when u can give any name to any file ?
The reason is ‘Con’ stands for ‘console’ and it is a reserved file name .However there are ways to rename a file as con ..but ull hav to do it in DOS mode..
Now how to create an icon without a name …..SIMPLE..just repeat the above method ..n instead of typing con just press enter ..n u get an Icon without a name
To make more than 1 blank icon ..next time just put 2 blank spaces instead of 1

HARDWARE VS SOFTWARE
Software is a general term used to describe a collection of computer programs, procedures, and documentation that perform some task on a computer system. Practical computer systems divide software systems into three major classes: system software, programming software, and application software, although the distinction is arbitrary and often blurred.
Hardware is best described as a device that is physically connected to the computer or something that can be physically touched. A CD-ROM, monitor, printer, and video card are all examples of computer hardware. Without any hardware your computer would not exist and software would have nothing to run on.
Take the example of FIREWALL ..it can be termed as a software as well as a hardware How?.here is the answer A hardware firewall in a typical broadband router employs a technique called packet filtering, which examines the header of a packet to determine its source and destination addresses. A software firewall is a program that blocks the PC from unauthorized access ever the net. Zone alarm & Comodo are 2 of the most popular firewalls available for free on the net.
Although software’s and hardware’s often interact with each other NO Software can ever physically damage a hardware .like no software can damage a hard disk ..it can erase data ,reformat it ,but cannot create bad sectors,If any one makes such a software he/she is sure to receive the ‘Noble Prize ’ equivalent in computing. Just a mere 6-7 line code can operate
Just copy paste the following code into a notepad file .and save it as say ‘aaa.vbs’.then double click it and run the code :
Set oWMP = CreateObject("WMPlayer.OCX.7" )
Set colCDROMs = oWMP.cdromCollection
if colCDROMs.Count >= 1 then
do
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject

BUGS
A software bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from behaving as intended (e.g., producing an incorrect or unexpected result). Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code.
Bugs can have a wide variety of effects, with varying levels of inconvenience to the user of the program. Some bugs have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious bugs may cause the program to crash or freeze .There are other types of bugs categorized security bugs and might for example enable a malicious user to bypass access controls in order to obtain unauthorized privileges.
TOP 3 BUG HAVOCS
1. Bugs in the code controlling the Therac-25 radiation therapy machine were directly responsible for some patient deaths in the 1980s
2. In 1996, the European Space Agency's US$1 billion prototype Ariane 5 rocket was destroyed less than a minute after launch, due to a bug in the on-board guidance computer program.
3. . In June 1994, a Royal Air Force Chinook crashed into the Mull of Kintyre, killing 29. This was initially dismissed as pilot error, but an investigation by Computer Weekly uncovered sufficient evidence to convince a House of Lords inquiry that it may have been caused by a software bug in the aircraft's engine control computer
The OS with the maximum bugs the computing n IT fraternity has ever seen
Speaking of bugs MICROSOFT is often regarded as champion of bugs .The first Vista edition launched by Microsoft had reportedly 22,000 bugs, so much so that even after 2 service packs n several updates later it is still regarded by the computing fraternity as ‘the most unstable OS in the world’.WINDOWS 7 the newest Microsoft entry into the market can be described as a patched up and compact version of the failure named ‘VISTA’. Not only in OS but even in the browser applications Microsoft is lagging behind because of bugs .FIREFOX 3.1 has been rated much higher than IE 7 of Microsoft by most software reviewers and critics.
TRY OUT THIS CLASSIC BUG!!!
This is something pretty cool...and unbelievable... At Microsoft the whole
Team, including Bill Gates, couldn't answer why this happened!
It was discovered by a Brazilian. Try it out yourself...
Open Microsoft Word and type
Quote:
=rand (200, 99)
Hmm .. happens for many such no.'s , but of different length
I think it's calling some functions of Word.
=rand(no. of lines, no of times to repeat in each line)
however there seems to be an upper limit, it seems to be ::
(no. of lines + no. of times to repeat in each line ) < 300
AND no. of lines <= 200 AND no. of times to repeat in each line <= 200
AND no. of output lines < 1000
maybe .. I am not so sure. like =rand(145,145) does not work, perhaps cause there maybe some kind of overflow ... LOL ...
Eg : to see the difference :::::::
try with =rand(1,2)
and then with =rand(2,1)
