THE TWITTER SEMINAR ON THE DEVELOPMENT OF ERROR FREE SOFTWARE HAS BEGUN

HAS A MAJOR ERROR FREE SOFTWARE APPLICATION BEEN DEVELOPED?

When was the last time that a computer error created a real problem for you?

An ATM failure occurred when I was transferring $1000. It took the bank 5 hours to find it.

Have you heard that the development of error-free software was economically unachievable?

Would you believe it if I told you that a major error-free application was developed in 1968.

IBM developed the PL/1 compiler in 1968. It was error-free.  Unlike Fortran, it had no bug list.

How did IBM do it?  They developed it in strict compliance with the principles of simple-precedence.

WHATIFWE developed other applications in strict compliance with principles of simple-precedence?  Can we do it?
