Perl special variable cheat sheet

Hi all,

Again this will be a post for the perl lover.
Recently I was browsing, I  came across the blog of Peteris Krumins blog. The blog has list of interesting article concerning Perl, awk and sed.

One of the article, that attracted my regex mind was his Perl special variable cheat sheet. His 4 page cheat sheet is really easy and collate all the special variable, you may  require play code golf. (I really did not know , Perl has that many special variable)
You can download the cheat sheet here  or from the original link.

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.

runtime error opening '.......'" for reading: -102 (file not found.). on virtual box

Recently I had an issue in regard to the"runtime error opening '.......'" for reading: -102 (file not found.)" on my virtual box . I did the search and could not found any proper solution in a single post..

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!

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.

zumbl - website/app to chat stranger

Hi All,

if you have some free time and really do not know what to do .... this might post  might be interesting to you.
Recently I came across an app called "zumbl" where you can "chat as stranger to a stranger".
How it is different from other web service like omegle
first it message chat so no cam required
second it has do and donot and kind of moderated chat.
So person you are chatting with can assign you "tags" and "scores" and if you accumulated too much negative score you might be even get banned for couple of day.


SO what r u waiting for ... just go ahead download this app and experience it yourself.

The case for updating ubuntu if you are a 12.04 or 12.10 user

I am a user of Ubuntu 12.10 (Quantal Quetzal) user and have been getting the usual prompts from canonical to upgrade to 13.04. Well on paper both look almost the same. So I decided to try out the latest Ubuntu named Raring Ringtail. So I took out my old but still trustworthy acer laptop (The specs are core2duo 2ghz and 4GB RAM) and updraded my linux distro. 

Well first look it looked the same but onceI clicked on the Unity icon I discovered a new set of snazzy icons. I was impressed as it gave a premium feel to the whole GUI (think apple). The laptop did respond a trifle better and over a period of few days noticed the resource usage and memory usage was improved . But then I was still facing the system errors which were a common feature in Quantal Quetzal. Some things never change so much so for being snazzy as an APPLE. But anyways I liked the latest iteration but as a general user didn't find much of improvements when it came to Quantal Quetzal.

Now comes the key question to upgrade or not? Well if its work we are talking about I would still stick to the 12.04 precise pangolin release just for the fact that it has a 5 year support cycle while Quantal Quetzal has a 18 month update cycle while the latest Raring ringtail its just 9 months. So no more security patches for raring Ringtail while precise Pangolin smokes out all the competition to all the other releases. When it came to choose between Precise Pangolin and Quantal Quetzal I was happy to upgrade because Quantal Quetzal provided way much more in terms of eye candy and some fancy packages but after the upgrade I had realised that precise Pangolin was a real good release with less memory and CPU utilization as compared to Quantal Quetzal. Well the eye candy does come at a cost.

So my verdict If you are on Precise pangolin then its a no brainer to update to the Raring Ringtail update but if on the Quantal Quetzal well its a 50-50 split opinion to upgrade or wait till september for the next iteration.

vi - opening second file in split screen

Some we get in need of comparing two different files for over the section or lines.
To open the new file in the split window all u need to follow the below steps




to open  already existing file
vi file_name

now type
:new file_name

This will split the screen horizontally 

Split the screen in vi - horitzontally or vertically

Most of us have some time in need to compare the two files to compare same file on different line or section,

then you will find 'split' can be very handy.

 the simplest usage is to type 'split' command that will split the screen horizontally.

Nostalgia in the times of Instant GRatification!!!

This week in India was an memorable one. No no strikes, no scandals, no corruption this week but rather two very important announcements cam through which kind of made me nostalgic.

The first bit of news was that Telegram would be switched off in India from July 15. Am I sad...welll not exactly. i can't remember when was the last time when i sent or received a telegram but I do remember we had to write some as part of our English syllabus in class 10. Yes I remember the last telegram which our family received was from a cousin during the Latur earthquake to tell us that he's safe. And it was exorbitantly priced even for those times. But I guess in the age of SMS and IM it was a relic of old times

The second news was closing of Music World Stores. I still remember the first music world store at Ansal Plaza at Delhi. It was the best place to be. on a hot delhi day. I could listen to all the latest tracks across genres on the listening stations and the variety was mind boggling. My firts tryst with serious english music was at the music world.  But I never realised when youtube became the primary source of music for me and then camethe online music streaming services where I could create my own playlists and won't have to worry either about carrying CD's or illegally downloading music

SO RIP two icons from different era are no more

Interval tree and next generation sequencing

Recently I was working with some genome data on my leisure project. I had some huge number of coordinate of gene and various transcription element . The task was to fetch elements name  between the coordinate given by the required inputs range of the gene.

Though, the above problem challenge can be easily solved, using various approaches, but I wanted to have it best optimized way. Little R&D and small discussion with my programer cousin Najeeb,  I came across a data structure called "interval tree" .I decided to give a try and begin my exploration for this data structure.

Proxmate - Accessing video/music content sites exclusive to USA

How amny times it has happened that we have had to wait for latest episodes of some famous american sitcoms to available illegally on the internet? Many a times we have used the much maligned torrents to illegally download series and movies. The irony of all this is services like hulu or even youtube (For US users) has many episodes available instantly. Even CBS provides free episodes on its sites but it is not available to users outside USA?

So after much thoughts people started using proxy servers but again the age old problems started cropping up : advertisements. malware's, flash not working etc. I felt at times to pull out my hair. Why in India or in many other countries across the world we are not able to view due to some stupid licensing issues. Even if I have to access sites like pandora,turntable.fm which are indeed very good sources of music I can't.

So enough of beating around the bush and crying. I recently came across a plug-in for chrome and firefox which goes by the name of PROXMATE.  And it is simply a wonderful plugin because it uses the proxies of a US based software without the user having to do anything and magic happens. Now I have unhindred access to hulu, pandora and what not but its a amazing piece of work. Simple yet effective. Now I don't have to hunt for proxies or download stuff illegally from the torrents.
The home page of the plug-in is http://proxmate.dave.cx/  and please donate generously to keep this wonderful plug-in alive.

6 Techniques to Reduce Camera Shake - by Natalie Norton

In this post, photographer Natalie Norton explores 6 ways you can hand hold lenses at low apertures and low shutter speeds and still avoid blurry images caused by camera shake.

She says..."I’m a mover and a shaker in general, and this is particularly true when I'm on a shoot. I'm twisting and turning, climbing and jumping and to top it all off, I DO NOT have a steady hand, plain and simple."

Here are 6 options for avoiding camera shake and achieving crisp, delicious images no matter the length of the lens, no matter the shutter speed.


1. Elbows In

As often as possible pull your elbows in to your body and exhale completely before depressing the shutter. When you’re working with a wide aperture or low shutter speed (or both), even a breath can introduce shake. Pulling your elbows tight to your body can really help keep you steady. I also press my elbows firmly into my chest for even greater stability.

How to use external HDD or a Pen drive across the major OS' like Windows, OS X and Ubuntu without formatting ?

This post arises from my initial struggles of using a MAC ( At the time of writing I have managed to blow up my macbook pro and back to  linux system and an occasional Windows user). I always had a ntfs partition on my HDD's and also my pen drive because one fine day I realized that the FAT32 file system which is so popular can't handle files of sizes greater than 4 GB. Yes i know that's atrocious in this age of blue ray and HD videos. So I converted all my disks to NTFS. All was hunky dory till I met my nemesis.

I got my MAC and transferred loads of file from windows and linux to my new sweetheart. After I decided I needed to create backups of some photos and other mundane stuff and to my utter shock I couldn't write anything on my HDD. I panicked thinking my HDD's are dead and with that my data gone. But I again plugged in my HDD to the old faithful Linux system lying in the corner. and to my surprise it was working just fine. I went back to my mac (yes I am ungrateful but you got to admit mac looks cool and the hardware is the best optimized for the software) and fired up my browser and looked at the issue. NTFS being a windows proprietary file formatting system was despised by Apple and Apple used something called HFS file system . And we all know that Linux also uses ext4 file journalling system. And HFS file systems were not supported on windows . I was sad at the turn of events and then saw complicated solutions to enable ntfs mounting on MAC and they were highly unstable.

how to create a strong password that you can easily remember?

"Treat your password like your toothbrush. Don’t let anybody else use it, and get a new one every six months." ~Clifford Stoll

Information technology  has impacted more than anything else around, in the current century. Now, you can  share your thoughts without barrier and censorship, get in touch with lik- minded people and  follow your interest through these available  technological toys and sharing forum.
Same, has create a new ground and opportunity,  for few people to exploit these technology for there own malicious benefits (cyber crime) . The few things, these unethical hacker do is to guess or steel your password for identity thefts on social media or take advantage of this information hack to make monetary transaction.

So to prevent us scenario, it would be best to make strong password and keep changing it regularly (at-least twice a year) . It might be easy to create a strong one , but how to remember it can be difficult task.
While making your password always keep the following point in your mind.

sublime-text ! a fantastic programming editor for Window/Linux/Mac

Programming editors are one of the most personal thing for a coder. This choice may vary as per the language he/she be taking up for the current project. Switching of editor may be also due in availability of the same in the other OS environment.                                               I started my coding in window environment in C and in few days become the fan of Notepad++.Later on as a Bioinformatics, I had to change the Operating system environment for my project and had  to program in Linux (Ubuntu).

As the  notepad++ was not supported  (still not supported) , I started looking for a nearest option . I started with gedit (the default text editor in linux), then I switched to Kate,  to Vi and then to geany. Geany was easy and some of the feature made me very comfortable  eg displaying of all function on side bar.

(256Kb  for Rs.799 for unlimited plan) (Now the same applicable for water supply connection, if you living in some metro city) and the maximum from this speed you can manage was to do, was of make e-ticketing for railways, checking mail account and very popular social networking site orkut (still alive!) in India.
