Beginer's All-purpose Symbolic Instruction Code
In computer programming, BASIC an acronym for Beginner's All-purpose Symbolic Instruction Code refers to a family of high-level programming languages. It was originally designed in 1963, by John George Kemeny and Thomas Eugene Kurtz at Dartmouth College, to provide access for non-science students to computers. At the time, nearly all computer use required writing custom software, which was something only scientists and mathematicians tended to do. The language became widespread on home microcomputers in the 1980s, and remains popular to this day.
Prior to the mid-1960s, computers were extremely expensive tools used only for special-purpose tasks. A simple batch processing arrangement ran only a single "job" at a time, one after another. During the 1960s, however, faster and more affordable computers became available. With this extra processing power, computers would sometimes sit idle, without jobs to run.
Programming languages in the batch programming era tended to be designed, like the machines on which they ran, for specific purposes (such as scientific formula calculations or business data processing or eventually for text editing). Since even the newer less expensive machines were still major investments, there was strong tendency to consider efficiency to be the most important feature of a language. In general, these specialized languages were difficult to use and had widely disparate syntax.
As prices decreased, the possibility of sharing computer access began to move from research labs to commercial use. Newer computer systems supported time-sharing, a system which allows multiple users or processes to use the CPU and memory. In such a system the operating system alternates between running processes, giving each one running time on the CPU before switching to another. The machines had become fast enough that most users could feel they had the machine all to themselves. In theory, timesharing reduced the cost of computing tremendously, as a single machine could be shared among (up to) hundreds of users.
The original BASIC language was designed in 1963 by John Kemeny and Thomas Kurtz and implemented by a team of Dartmouth students under their direction. BASIC was designed to allow students to write programs for the Dartmouth Time-Sharing System. It intended to address the complexity issues of older languages with a new language design specifically for the new class of users time-sharing systems allowed — that is, a less technical user who did not have the mathematical background of the more traditional users and was not interested in acquiring it. Being able to use a computer to support teaching and research was quite attractive enough. In the following years, as other dialects of BASIC appeared, Kemeny and Kurtz' original BASIC dialect became known as Dartmouth BASIC.
The eight design principles of BASIC were:
1. Be easy for beginners to use.
2. Be a general-purpose programming language.
3. Allow advanced features to be added for experts (while keeping the language simple for beginners).
4. Be interactive.
5. Provide clear and friendly error messages.
6. Respond quickly for small programs.
7. Not require an understanding of computer hardware.
8. Shield the user from the operating system.
The language was based partly on FORTRAN II and partly on ALGOL 60, with additions to make it suitable for timesharing. It had been preceded by other teaching-language experiments at Dartmouth such as the DARSIMCO (1956) and DOPE (1962 implementations of SAP and DART (1963) which was a simplified FORTRAN II). Initially, BASIC concentrated on supporting straightforward mathematical work, with matrix arithmetic support from its initial implementation as a batch language and full string functionality being added by 1965. BASIC was first implemented on the GE-265 mainframe which supported multiple terminals. Contrary to popular belief, it was a compiled language at the time of its introduction. It was also quite efficient, beating FORTRAN II and ALGOL 60 implementations on the 265 at several fairly computationally intensive programming problems such as maximization Simpson's Rule.
The designers of the language decided to make the compiler available without charge so that the language would become widespread. They also made it available to high schools in the Dartmouth area and put a considerable amount of effort into promoting the language. As a result, knowledge of BASIC became relatively widespread (for a computer language) and BASIC was implemented by a number of manufacturers, becoming fairly popular on newer minicomputers like the DEC PDP series and the Data General Nova. The BASIC language was also central to the HP Time-Shared BASIC system in the late 1960s and early 1970s. In these instances the language tended to be implemented as an interpreter, instead of (or in addition to) a compiler.
Several years after its release, highly-respected computer professionals, notably Edsger W. Dijkstra, expressed their opinions that the use of GOTO statements, which existed in many languages including BASIC, promoted poor programming practices.[2] Some have also derided BASIC as too slow (most interpreted versions are slower than equivalent compiled versions) or too simple (many versions, especially for small computers left out important features and capabilities).
Notwithstanding the language's use on several minicomputers, it was the introduction of the MITS Altair 8800 microcomputer in 1975 that provided BASIC a path to universality. Most programming languages required more memory (and/or disk space) than were available on the small computers most users could afford. With the slow memory access that tapes provided and the lack of suitable text editors, a language like BASIC which could satisfy these constraints was attractive. BASIC also had the advantage that it was fairly well known to the young designers who took an interest in microcomputers. Kemeny and Kurtz's earlier proselytizing paid off in this respect. One of the first to appear for the 8080 machines like the Altair was Tiny BASIC, a simple BASIC implementation originally written by Dr. Li-Chen Wang, and then ported onto the Altair by Dennis Allison at the request of Bob Albrecht (who later founded Dr. Dobb's Journal). The Tiny BASIC design and the full source code were published in 1976 in DDJ.
In 1975, MITS released Altair BASIC, developed by Bill Gates and Paul Allen as Micro-Soft. The first Altair version was co-written by Gates, Allen and Monte Davidoff. Versions of Microsoft BASIC soon started appearing on other platforms under license, and millions of copies and variants were soon in use; it became one of the standard languages on the Apple II (based on the quite different 6502 MPU). By 1979, Microsoft was talking with several microcomputer vendors, including IBM, about licensing a BASIC interpreter for their computers. A version was included in the IBM PC ROM chips and PCs without floppy disks automatically booted into BASIC just like many other small computers.
Newer companies attempted to follow the successes of MITS, IMSAI, North Star and Apple, thus creating a home computer industry; meanwhile, BASIC became a standard feature of all but a very few home computers. Most came with a BASIC interpreter in ROM, thus avoiding the unavailable, or too expensive, disk problem. Soon there were many millions of machines running BASIC variants around the world, likely a far greater number than all the users of all other languages put together.
There are more dialects of BASIC than there are of any other programming language. Most of the home computers of the 1980s had a ROM-resident BASIC interpreter.
The BBC published BBC BASIC, developed for them by Acorn Computers Ltd, incorporating many extra structuring keywords, as well as comprehensive and versatile direct access to the operating system. It also featured a fully integrated assembler. BBC BASIC was a very well-regarded dialect, and made the transition from the original BBC Micro computer to more than 30 other platforms.
During this growth time for BASIC, many magazines were published such as Creative Magazine that included complete source codes for games, utilities, and other programs. Given BASIC's straightforward nature, it was considered a simple matter to type in the code from the magazine and execute the program. Different magazines were published featuring programs for specific computers, though some BASIC programs were universal and could be input into any BASIC-using machine.
Many newer BASIC versions were created during this period. Microsoft sold several versions of BASIC for MS-DOS/PC-DOS including BASICA, GW-BASIC (a BASICA-compatible version that did not need IBM's ROM) and QuickBASIC. Turbo Pascal-publisher Borland published Turbo BASIC 1.0 in 1985 (successor versions are still being marketed by the original author under the name PowerBASIC).
These languages introduced many extensions to the original home computer BASIC, such as improved string manipulation and graphics support, access to the file system and additional data types. More important were the facilities for structured programming, including additional control structures and proper subroutines supporting local variables.
However, by the latter half of the 1980s newer computers were far more capable with more resources. At the same time, computers had progressed from a hobbyist interest to tools used primarily for applications written by others, and programming became less important for most users. BASIC started to recede in importance, though numerous versions remained available. Compiled BASIC or CBASIC is still used in many IBM 4690 OS point of sale systems.
BASIC's fortunes reversed once again with the introduction of Visual Basic by Microsoft. It is somewhat difficult to consider this language to be BASIC, because of the major shift in its orientation towards an object-oriented and event-driven perspective. While this could be considered an evolution of the language, few of the distinctive features of early Dartmouth BASIC, such as line numbers and the INPUT keyword, remain.
Many BASIC dialects have also sprung up in the last few years, including Bywater BASIC and True BASIC (the direct successor to Dartmouth BASIC from a company controlled by Kurtz). Recently, the remaining community using Microsoft's pre-Visual Basic products have begun to switch wholesale to FreeBASIC, a GPLed compiler which has been in the process of moving BASIC onto a GCC backend. Many other BASIC variants and adaptations have been written by hobbyists, equipment developers, and others, as it is a relatively simple language to develop translators for. An example of an open source interpreter, written in C, is MiniBasic.
The ubiquity of BASIC interpreters on personal computers was such that textbooks once included simple TRY IT IN BASIC exercises that encouraged students to experiment with mathematical and computational concepts on classroom or home computers.

Its been more than a year I've joined the Sri Lanka Queens and Presidents Scout Guild. It is loads of fun working with elder people and so much to learn. The Guild is growing each year since its inception. Hoping to help the younger generation with the experince i gained as a cub/scout/senior scout/rower scout for 12 years. Once a Scout Always a Scout ! BE PREPARED !
Ruby is…
A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
Top Ruby Features according to Michael Neumann
interpreted
advantage:
* immediately executable (no waiting period while compiling)
disadvantage:
* execution speed much slower than with compiler (e.g. Pascal, C++)
object-oriented
In Ruby everything is an object (as in Smalltalk). Ruby did not use multiple-inheritance, but the same is possible through mix-in.
portabel
Ruby is highly portable, so that one and the same Ruby program runs without changes under UNIX, Windows, DOS, Mac, BeOS and others. Of course that's only true unless using platform-specific modules, like for example some GUI's for UNIX or WinGKR (Win32 GUI Kit for Ruby).
advantage:
* less expenditure (only one program had to be managed)
* wider distribution of the program (because it runs on serveral platforms)
untyped
Variables in Ruby have no type, such as in Smalltalk, BASIC or Python. Variables behave as placeholders, but data is typed. In C++ or Pascal, variables are typed (e.g. int / Integer), but the data in the memory is not, that is you cannot recognize if it's a String or an Integer. In C++ or Pascal the types are checked at compile-time, whereas Ruby checks the type at runtime, so if the object understands the message (method-call) is first known after a method-call. You do not have to declare variables, because they are automatically created when you use them.
automatic memory-management (garbage collection)
You do not have to release allocated memory in Ruby (as you have to do in Pascal/C++ with dispose/free). No longer used memory, i.e. memory-frames where no variable points to, are automatically freed by the garbage collector.
advantage:
* no memory leaks
* fewer crashs or errors
* more easier, faster and more uncomplicated programming, because you do not have to look after the memory management.
disadvantage:
* less speed (about 10%). But Ruby is an interpreted language, where 10% are not so much.
easy and clear syntax
Ruby is based among others on the syntax of Eiffel (Ada)
* well legible
* ease to understand
* easy to learn
* fewer errors
Ruby often offers an additional C++ similar syntax
* hardly changes for those, who come from C++ (Perl) to Ruby
* less code ==> faster
advanced OO-concepts and features
* singleton methods
* mix-in instead of multiple-inheritance
* operator overloading
* method-overloading (such as C++)
* exception handling
* iterators and closures
* meta-class
* build-in pattern-matching (like Perl)
other features
* Ruby is free, also for commercial applications
* many existing libraries make programming easy
* Ruby is permanently developed, without loosing backward-compatibility
* There are interfaces to Python, Perl and Java. Thus existing programs can be reused.
* Many important data-structures are available (such as dynamic arrays (lists), strings, bignum, complex, ....)
* Easy to extend through C/C++ with dynamic (DLL's) or static binding.

A ceremony that elicited the true meaning of freedom
National Flags fluttered proudly at Galle Face Green as the 59th anniversary of Independence dawned yesterday. The colourful National Day celebration marking Sri Lanka's liberation from foreign domination was held at Galle Face yesterday, with President Mahinda Rajapaksa participating as the Chief Guest.
The arrival of President Rajapaksa and First Lady Shiranthi Rajapaksa was heralded by the blowing of trumpets by the Sri Lanka Army. They were received by Prime Minister Ratnasiri Wickramanayake, Public Administration Minister Karu Jayasuriya, Home Affairs Minister R. Gajadeera, Western Province Governor Alavi Moulana and Western Province Chief Minister Reginald Cooray.
The Chief of Defence Staff, the three Services Commanders and the IGP conducted the President to the Main Flag Post where he hoisted the National Flag, amidst the beating of Magul Bera and the blowing of Conch Shells by Artists of the Ministry of Cultural and National Heritage. This was followed by a 21 Gun Salute to the President, who later addressed the Nation.
The National Anthem was sung by a bevy of 100 schoolgirls representing seven Girls' Schools in Colombo - Vishaka Vidyalaya, Sirimavo Bandaranaike Vidyalaya, Devi Balika Vidyalaya, St. Bridget Convent, Janadhipathi Vidyalaya, Ramanathan Hindu Balika Vidyalaya, Muslim Ladies College and three from outstations - Kurunegala Maliyadeva Balika Vidyalaya, Debarawewa National School and Dehiathakandiya National School.
Jayamangala Gathas and "Devo Vassathu Kalena" was also sung by 25 school girls of seven selected schools from these 10 schools.
The colourful pageant ended with a 'March Past' by the Army, Navy, Air Force, Police, STF and the Civil Security Forces who portrayed their strength and dexterity. Naval offshore patrolling and surveillance crafts, Sayura, Sagara, Nandimithra, Samudura, Shakthi and Udara, displayed their manoeuvrability skills in the sea off Galle Face Green, while Kfir and MiG fast-attack aircraft of the Air Force displayed their air power.
This was followed by 'Group Performances' including 'Ves Netum' and traditional drums.
Yesterday's ceremony reflected the will of the Nation to face the myriad challenges of the present and the future as one, devoid of any ethnic, religious or political differences.

'You've got to find what you love,' Jobs says
This is the text of the Commencement address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, delivered on June 12, 2005.
I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I've ever gotten to a college graduation. Today I want to tell you three stories from my life. That's it. No big deal. Just three stories.
The first story is about connecting the dots.
I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out?
It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course." My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college.
And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting.
It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example:
Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer, was beautifully hand calligraphed. Because I had dropped out and didn't have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and san serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating.
None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, its likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backwards ten years later.
Again, you can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
My second story is about love and loss.
I was lucky — I found what I loved to do early in life. Woz and I started Apple in my parents garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation — the Macintosh — a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating.
I really didn't know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down - that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me — I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over.
I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.
During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the worlds first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple's current renaissance. And Laurene and I have a wonderful family together.
I'm pretty sure none of this would have happened if I hadn't been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don't settle.
My third story is about death.
When I was 17, I read a quote that went something like: "If you live each day as if it was your last, someday you'll most certainly be right." It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "No" for too many days in a row, I know I need to change something.
Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.
About a year ago I was diagnosed with cancer. I had a scan at 7:30 in the morning, and it clearly showed a tumor on my pancreas. I didn't even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor's code for prepare to die. It means to try to tell your kids everything you thought you'd have the next 10 years to tell them in just a few months. It means to make sure everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes.
I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endoscope down my throat, through my stomach and into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated, but my wife, who was there, told me that when they viewed the cells under a microscope the doctors started crying because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and I'm fine now.
This was the closest I've been to facing death, and I hope its the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept:
No one wants to die. Even people who want to go to heaven don't want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life's change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960's, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: it was idealistic, and overflowing with neat tools and great notions.
Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its course, they put out a final issue. It was the mid-1970s, and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath it were the words: "Stay Hungry. Stay Foolish." It was their farewell message as they signed off. Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you.
Stay Hungry. Stay Foolish.
Thank you all very much.

I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I've ever gotten to a college graduation. Today I want to tell you three stories from my life. That's it. No big deal. Just three stories.
The first story is about connecting the dots.
I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out?
It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course." My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college.
And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting.
It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example:
