Common Lisp: Inside Sabre

bugbear writes "I just got permission from the author (Carl de Marcken of ITA Software) to publish this email, which describes the inner workings of Sabre, the flight search software that the airlines and travel agencies use. It is a case study in cheap Linux/Intel, NT/Intel and Hpux boxes replacing mainframes, and also the use of lisp and other languages in a server-based app. Update: 01/16 13:45 GMT by H :RawDigits writes "Common Lisp: Inside Sabre - correction. The Lisp engine is used by Orbitz, and not Sabre. Sabre still maintains mainframe systems for their booking. I should know, I am sitting in the Orbitz NOC right now ;)"

That is some crazy-fun processing power!
I wish I had 200 of those babies. My 3D Studio rendering would fly like nobodies business :)


Would it be fair to say that you are imagining a beowulf cluster of these?

Ahem . . . . Bad joke, I know.

Re:Sabre is its own interesting case study

It used to. I still remember the old nasty green screen dumb terminals that every airport and agency had. Nowadays, they use an emulator on a PC to get the same functionality.
