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 ;)"

My name is Diana and I need a rich man. Any volunteers ?
Our car-manufacturing company has developed a new revolutionary business model for making cars.
We give away the cars for free and then we sell services for those cars! If you want to we can clean your car, wax it or you can use some of our other services.
We get cash from a couple of VC's, the rest of them simple don't "get it". If we need more we just call "the suits".
Jon uses Linux.
Linux itself is practically an illegal operating system. Much of its code is stolen from BSD and leaked windows source. The hierarchy of linux users is much like that of the drug trade. First there is the head leader of the organization, a member of the Russian Mafia named Linus Torvenstov. Linus gives his code to 'distributors' in the same way drug importers sell their goods to large distributors. The distributors are allowed to change the code, the same way drug dealers sometimes change and process drugs. They are also allowed to set their own prices, with low quality linux distro's going for 20$ a piece and the finest quality linux going for well over 1000$. Linux distributors have names that cater to their users, the same way designer drugs like ecstasy variants have hip names. 'Red Hat' is a version of the linux drug for communists. 'Slackware' is for people who slack off and are on welfare. 'Yellow dog' is a version of linux for alcoholics with jaundice. And the list goes on.
Linux has staked a footing in communist countries such as China and Cuba. It is popular because it does not contain the anti-terrorism features of windows XP that any honest person would want on their computer. China has successfully used linux to control their nuclear weapons aimed at Japan and america. This is extremely unsafe as linux is an unstable operating system not suitable for mission critical tasks. America's nuclear arsenal is controlled by stable pentium-4 based pc's with windows XP government edition. So far there haven't been any accidents, and it is doubtful there will be as windows has auto-update systems that keep it hacker-proof. Crackers and hackers and communist nations that needed an operating system geared at immoral terrorist activities on the other hand use Linux.
Linux is a popular OS with pedophiles. It has encryption features which make is easy for someone to hide illegal pictures of 5 year old's in horrifying situations. Fortunately, some countries such as UK have created laws that make it a crime to not reveal encryption passwords, and hopefully this will help curb the linux pedophile epidemic. Linux users have even created their own network called 'freenet' that is used almost exclusively for child porn distribution. A popular linux 'distro' for child porn is called 'Debian' which is Finnish for 'Child sodomization'. Debian was apparently developed from stolen windows 3.11 source and the developers are scattered throughout the world and haven't all been tracked down and executed by the CIA yet.

He left out the amazon 1-click patent. That certainly ranks up there. Maybe it's time to patent the 0-click mouse-over patent. "...the fool held the mouse over the image, he must have wanted to buy it..."
years ago I had a chat with some nice people in blue suits who wanted to know what I knew about an airline system in Kasnas City and what I knew about programming. Turns out that a friend of mine told the nice men in blue suits that I had taught him how to program. He was part of a group of "evil hacker" types and one of them had been running a multi channel BBS. The BBS had two lines and was running on a vic 20. Now the odd thing about this BBS is you could upload as much stuff as your 110 baud modem could choke on and weeks later it was still there. This was odd considering the best you could on a vic 20 was maybe 8 single sided floppys. It turns out that someone from this evil computer club had found out how to transfer stuff off to one of the backup mainframes and he was using that for storage and all the vic 20 was doing was multiplexing data streams and sending out ansi graphics. I still consider that one of the best all time hacks I've heard of.
I have used both Sabre and Orbitz. If you have ever used Orbitz, you know how bad it sucks. Its search engine produces wacky itineraries. Seriously, go give it a try and see for yourself. Sabre beats the hell out of Orbitz. Once again, the old-school mainframe system is superior.
Don't take my word for it. Go plug the same search into Travelocity and Orbitz and look at those results.
Wonderful Troll, and how exactly have you used SABRE??? That is the actual system, not some website and their system. Orbitz interfaces with SABRE to get information, but it is not equal to SABRE!!!!!!!!!!!!
Of course you're a troll, why do you care.
