Perl vs perl

The following discussion is an expansion on a question and answer which can be found in the perlfaq1 page of Perl's documentation, namely:
What's the difference between "perl" and "Perl"?
Sometimes you'll see "Perl" written, with a capital P, sometimes "perl", sometimes even PERL.
Confused? Not to worry, Israel.pm to the rescue :-)
The rules are actually quite simple:

• "Perl" should be used when one is writing about the language, for example:
  

  Perl is a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal).

• "perl" should be used when one is writing about the executable which interprets and compiles the Perl code, for example: the perl executable can usually be found at /use/bin/perl on Unix/Linux systems, or on c:\Perl\bin\perl.exe on Windows systems.
• The above two usage forms are not rigidly adhered to, even in Perl's documentation, but in any case you should never use "PERL".
  "PERL" is a backronym, so unless you are going to use it as a joke, don't. It is way overused and abused, and it is time to put it to rest.

There's a famous saying, attributed to Tom Christiansen, which says that Only perl can parse Perl
We'll leave you now to ponder these words of wisdom...

number sequence database for mathlover

Do you have a number sequence that came up your in your mind and think it is a unique in some way , then u have encountered into a discovery of new series of number like like prime number
1,2,3,5,7,11,13,17

The above is the series of the number are divisible by itself.

But before reporting it  and being happy for this accomplished task, do check it on number sequnce database. In integer database ,you can submit your  sequence and validate that is found or yet to be discovered.

Check out . Its is fun.

So Here I am telling the solution that worked for me.

Know Thy Complexities!!!!

Hi there!  This webpage covers the space and time Big-O complexities of common algorithms used in Computer Science.  When preparing for technical interviews in the past, I found myself spending hours crawling the internet putting together the best, average, and worst case complexities for search and sorting algorithms so that I wouldn't be stumped when asked about them.  Over the last few years, I've interviewed at several Silicon Valley startups, and also some bigger companies, like Yahoo, eBay, LinkedIn, and Google, and each time that I prepared for an interview, I thought to msyelf "Why oh why hasn't someone created a nice Big-O cheat sheet?".  So, to save all of you fine folks a ton of time, I went ahead and created one.  Enjoy!

U might have seen many of the techinical interview by Perl creator  but this interview is more about person Larry Wall u might not have heard off.

How to Write a Linux Virus in 5 Easy Steps (Courtesy Tom's Hardware)

It's easy for people to pick at Windows for being prone to virus and malware attacks. It's almost a given belief that if you're running a PC with a Windows operating system, you're much more susceptible to attacks than users with other operating systems.

But let's quickly look at the reasons for this. First, it isn't really Microsoft's fault. It isn't that Windows is technically inferior, it's that the majority of the world runs on Windows. This fact alone is very attractive for any virus coder or exploiter. As a virus writer, you'd want to attack the majority, not the minority.
