Comments Off on Codes that changed the world
Growing up with the Apple II, I learned to program in BASIC. Its line numbers, GOTOs and GOSUBs, and spaghetti code were unlike anything I would encounter later in my education. Perhaps for that reason, I never mastered a language like I did BASIC. While I was able to grasp Prolog and FORTRAN, the "pointers" of C++ were so incomprehensible to me that I eventually had to change majors to get away from it.
Had I continued down that programming path, I doubtless would've faced many other challenging concepts as I attempted to master yet more languages, like C Sharp, Perl, PHP, Ruby, and more. By some estimates, there are over 20,000 languages in existence, only a fraction of which I ever could've learned on the Apple II. Some are more practical than others, while others are of more historical significance.
The podcast, which debuted this month and ran for all of five episodes, covers four languages: FORTRAN, COBOL, BASIC, and Java, with a fifth episode discussing how so many different languages are able to coexist.
Of course, you can't discuss the rise of BASIC without the role the Apple II played, and vice versa:
BASIC enabled computing as we understand it today. When Apple was a two-man band building this thing called the Apple II, there were no other computers out there like it. So they had to put something on it that would allow individuals to program it themselves. Apple just wouldn't exist without BASIC. And Microsoft! The first thing that Microsoft did as a company was selling BASIC to run on other people's computers. The two biggest names in modern computing, Apple and Microsoft, both wouldn't've happened if it wasn't for BASIC.
BASIC celebrated its 50th birthday last year, earning it a cover story in Juiced.GS:
While researching that story, author Steve Weyhrich (who also pointed me to this podcast) delved into the resources available at Dartmouth College, where BASIC was invented. As part of its "BASIC at 50" commemoration, Dartmouth produced a free 38-minute documentary, Birth of BASIC:
If you want to learn more about other programming languages, Codes that Changed the World is available in iTunes. While it's unreasonable to expect all 20,000 languages to be covered, I do lament that the podcast's scope was limited to only five episodes, as I rather enjoyed these 15-minute encapsulations of technical topics for a lay audience. If the BBC or Krotoski ever produce more, I'll be first in line to listen!
