Why the Great Glitch of July 8th Should Scare You

“I wouldn’t be surprised if there is some mainframe code from the 1960s still running part of that beast.”

Consider this verification: much of United’s code exists unchanged from the 1960s. And Sabre — the biggest airline scheduling and booking company still in independent existence, which started life as American’s reservations system — still contains code from the initial system, written on and for IBM 7090 mainframes in 1958–1960. And its output is still more or less designed for a 2260/3270 in its native mode, and its text is still all-caps fixed-column-width… and is still available in EBCDIC.

This is not to mention OAG, about whom the less said the better.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
