Re: 20 Year Old technology
@yalanand, where did you see this C retirement info? That is language that i5 has compiler for, I never saw where IBM planned to retire it? I could see them stopping to enhance the compiler anymore by adding new features but can't believe IBM would hang companies out to dry who have applications written in C?
Great example though. I still use RPG on i5, which has origins back to 1960's. But the RPG today, especially the free format version, looks nothing like it did. It looks like modern language now. I use it for my server side, take AJAX calls from Extjs clients. I much prefer that over server scripting languages like PHP or using raw SQL from client side, much more secure calling compiled RPG programs. You don't buffer overflow the i5, get your code to run and then modify the o/s. As character on Living Color used to say "Homey don't play that!". :-)
Even the i5 o/s itself can hardly be labeled legacy, still the finest business o/s ever written (with apologies to MVS). They got to RISC 64 bit a decade ahead of Windows and without any of the pain. Would I implement Facebook or Natl Weather service on i5, heck no. Wrong tool for job. But any transaction based business not dealing with unstructered data, still the best and most secure server in the world.
