Great Inventors in Programming Language


Some of Inventor with detail below:
Dennis Ritchie C – Dennis Ritchie
Dennis Ritchie is an American computer scientist who invented the C programming language in 1972 for Bell Telephone Labs. Ritchie is co-author of the definitive book on C, The C Programming Language (also known as K&R in reference to the authors Kernighan and Ritchie). Ritchie also co-developed the Unix operating system, received the Turing Award in 1983 and the National Medal of Technology in 1998. Ritchie was head of Lucent Technologies System Software Research Department when he retired in 2007.

Bjarne StroustrupC++ – Bjarne Stroustrup
Bjarne Stroustrup is a Danish computer scientist and the Chair Professor of Computer Science at Texas A&M University. He invented C++ in 1979 (then called “C with Classes”) and wrote what many consider to be the the C++ bible, The C++ Programming Language.

James Gosling Java – James Gosling
James Gosling is a famous Canadian software developer who has been with Sun Microsystems since 1984 and is considered the father of the Java programming language, invented in 1991. Gosling did the original design of Java and implemented its original compiler and virtual machine.

Brendan Eich JavaScript – Brendan Eich
Brendan Eich is a computer programmer who created the JavaScript programming language for the Netscape Navigator web browser in 1995. He is now the Chief Technology Officer of the Mozilla Corporation.

Perl – Larry Wall
Larry Wall is a programmer and author, best known for his creation of the Perl programming language in 1987. A linguist working as a systems administrator for NASA, Wall developed Perl as a general purpose Unix scripting language to make report processing easier. Wall is also the co-author of Programming Perl (often referred to as the Camel Book), the definitive resource for Perl programmers.

PHP – Rasmus Lerdorf
Rasmus Lerdorf is a Danish-Greenlandic programmer and most notable as the creator of the PHP programming language. PHP began in 1994 as a set of Common Gateway Interface binaries that Lerdorf wrote in C to replace Perl scripts he had been using on his personal homepage. Lerdorf has been an Infrastructure Architecture Engineer at Yahoo! since 2002.

Python – Guido van Rossum
Guido van Rossum is a Dutch programmer best known as the author of the Python programming language. Python started as a hobby project: a scripting language descendant of ABC that would appeal to Unix/C hackers. In the Python community, Van Rossum is known as a “Benevolent Dictator for Life.” Van Rossum currently works at Google on Python development.

FORTRAN– John Backus
John Backus was an American computer scientist who led the team that invented FORTRAN, the first widely used high-level programming language. He also invented the Backus-Naur form (BNF), the notation used to define formal language syntax. Backus received W.W. McDowell Award in 1967, National Medal of Science Award in 1975, and the ACM Turing Award in 1977.

Tired from Coding ...Have a some fun!


A project manager, a computer programmer and a computer operator are driving down the road when the car they are in gets a flat tire. The three men try to solve the problem. The project manager said: "Let's catch a cab and in ten minutes we'll reach our destination." The computer programmer said: "We have here the driver's guide. I can easily replace the flat tire and continue our drive." The computer operator said: "First of all, let's turn off the engine and turn it on again. Maybe it will fix the problem." Suddenly a Microsoft software engineer passed by and said: "try to close all windows, get off the car, and then get in and try again." 


A Software Engineer, a Hardware Engineer and a Departmental Manager were on their way to a meeting. They were driving down a steep mountain road when suddenly the brakes on their car failed. The car careened almost out of control down the road, bouncing off the crash barriers, until it miraculously ground to a halt scraping along the mountainside. The car's occupants, shaken but unhurt, now had a problem: they were stuck halfway down a mountain in a car with no brakes. What were they to do?
"I know," said the Departmental Manager, "Let's have a meeting, propose a Vision, formulate a Mission Statement, define some Goals, and by a process of Continuous Improvement find a solution to the Critical Problems, and we can be on our way."
"No, no," said the Hardware Engineer, "That will take far too long, and besides, that method has never worked before. I've got my Swiss Army knife with me, and in no time at all I can strip down the car's braking system, isolate the fault, fix it, and we can be on our way."
"Well," said the Software Engineer, "Before we do anything, I think we should push the car back up the road and see if it happens again."


The boy is smoking and leaving smoke rings into the air. The girl gets irritated with the smoke and says to her lover: "Can't you see the warning written on the cigarettes packet, smoking is injurious to health!" The boy replies back: "Darling, I am a programmer. We don't worry about warnings, we only worry about errors."

Programming Languages are Like Cars Assembler: A formula I race car. Very fast but difficult to drive and maintain. FORTRAN II: A Model T Ford. Once it was the king of the road. FORTRAN IV: A Model A Ford. FORTRAN 77: a six-cylinder Ford Fairlane with standard transmission and no seat belts. COBOL: A delivery van. It's bulky and ugly but it does the work. BASIC: A second-hand Rambler with a rebuilt engine and patched upholstery. Your dad bought it for you to learn to drive. You'll ditch it as soon as you can afford a new one. PL/I: A Cadillac convertible with automatic transmission, a two-tone paint job, white-wall tires, chrome exhaust pipes, and fuzzy dice hanging in the windshield. C++: A black Firebird, the all macho car. Comes with optional seatbelt (lint) and optional fuzz buster (escape to assembler). ALGOL 60: An Austin Mini. Boy that's a small car. ALGOL 68: An Aston Martin. An impressive car but not just anyone can drive it. Pascal: A Volkswagon Beetle. It's small but sturdy. Was once popular with intellectual types. liSP: An electric car. It's simple but slow. Seat belts are not available. PROLOG/LUCID: Prototype concept cars. FORTH: A go-cart. LOGO: A kiddie's replica of a Rolls Royce. Comes with a real engine and a working horn. APL: A double-decker bus. It takes rows and columns of passengers to the same place all at the same time but it drives only in reverse and is instrumented in Greek. Ada: An army-green Mercedes-Benz staff car. Power steering, power brakes, and automatic transmission are standard. No other colors or options are available. If it's good enough for generals, it's good enough for you. Java: All-terrain very slow vehicle.

Life Before the Computer
An application was for employment
A program was a TV show
A cursor used profanity
A keyboard was a piano!
Memory was something that you lost with age
A CD was a bank account
And if you had a 3 ? inch floppy
You hoped nobody found out!
Compress was something you did to garbage
Not something you did to a file
And if you unzipped anything in public
You'd be in jail for awhile!
Log on was adding wood to a fire
Hard drive was a long trip on the road
A mouse pad was where a mouse lived
And a backup happened to your commode!
Cut - you did with a pocket knife
Paste you did with glue
A web was a spider's home
And a virus was the flu!
I guess I'll stick to my pad and paper
And the memory in my head
I hear nobody's been killed in a computer crash
But when it happens they wish they were dead!

A grade school teacher was asking his pupils what their parents did for a living. "Tim, you be first. What does your mother do all day?"
Tim stood up and proudly said, "She's a doctor."
"That's wonderful. How about you, Amy?"
Amy shyly stood up, scuffed her feet and said, "My father is a mailman."
"Thank you, Amy" said the teacher. "What does your parent do, Billy?"
Billy proudly stood up and announced, "My daddy plays piano in a whorehouse."
The teacher was aghast and went to Billy's house and rang the bell. Billy's father answered the door. The teacher explained what his son had said and demanded an explanation. Billy's dad said, "I'm actually a system programmer specializing in TCP/IP communication protocol on UNIX systems. How can I explain a thing like that to a seven-year-old?"

XML Interview Questions and Answers

1.What is XML?
XML is the Extensible Markup Language. It improves the functionality of the Web by letting you identify your information in a more accurate, flexible, and adaptable way.

It is extensible because it is not a fixed format like HTML (which is a single, predefined markup language). Instead, XML is actually a metalanguage—a language for describing other languages—which lets you design your own markup languages for limitless different types of documents. XML can do this because it's written in SGML, the international standard metalanguage for text document markup (ISO 8879).
In brief -

    * XML stands for EXtensible Markup Language
    * XML is a markup language much like HTML
    * XML was designed to carry data, not to display data
    * XML tags are not predefined. You must define your own tags
    * XML is designed to be self-descriptive
    * XML is a W3C Recommendation



 2.What are XML syntax rules?
 Ans.
   The syntax rules of XML are very simple and logical. The rules are easy to learn, and easy to use.

    * All XML elements must have a closing tag
    * XML tags are case sensitive
    * XML elements must be properly nested
    * XML document must have a root element
    * XML attribute values must be quoted
    * White-space is preserved in XML
    * XML Stores new line as LF


3.How can XML be used?
Ans.
XML is used in many aspects of web development, often to simplify data storage and sharing.

    * XML Separates Data from HTML
    * XML Simplifies Data Sharing
    * XML Simplifies Data Transport
    * XML Simplifies Platform Changes
    * XML Makes Your Data More Available
    * XML is Used to Create New Internet Languages


4.What are the difference between XML and HTML.
Ans.
XML is not a replacement for HTML.

XML and HTML were designed with different goals:

    * XML was designed to transport and store data, with focus on what data is.
    * HTML was designed to display data, with focus on how data looks.

HTML is about displaying information, while XML is about carrying information.
Why is XML such an important for development?
XML is now as important for the Web as HTML was to the foundation of the Web.

    * It is the most common tool for data transmissions between all sorts of applications, and is becoming more and more popular in the area of storing and describing information.
    * In most web applications, XML is used to transport data, while HTML is used to format and display the data.
    * XML allows the author to define his own tags and his own document structure.

XML allows the flexible development of user-defined document types. It provides a robust, non-proprietary, persistent, and verifiable file format for the storage and transmission of text and data both on and off the Web; and it removes the more complex options of SGML, making it easier to program for.
What is SGML (Standard Generalized Markup Language)?
An international standard for markup languages. The basis for HTML and XML.
How do you write comments in XML?
XML comments are written the same way as HTML comments. i.e.

< !--this is a comment-- >.
The XML processor is not required to pass this information on to the user agent, i.e. the piece of software that is converting the document into some thing useful, but XML also uses CDATA sections which is used to escape blocks of text containing mark up.
