TRUTH OF THE MATTER : IBM originally support SNA before TCP/IP was widely in use so when IBM finally got around to implementing TCP/IP on the mainframe (around 1996) they did a shitty job (they didn't even include function prototypes in the header files) and they charged for it. It ran poorly and many of the functions were not syntacly correct. Since then however, they have complete rehauled the TCP/IP stack, corrected their implementation to match all standards and TCP/IP is an integrated part of the OS390.
As for talking SNA to an ip farm, having supported and coded to both TCP/IP and SNA, with OS390 OpenEdition - TCP/IP is by all means the way to go. As per usage of the mainframe, trust me there are plenty.
All of the above information I hold to be true from personal experience.
It was not the geeky loners that were dangerous when I went to school. It was the pack of 4-5 steriod injecting meatheads who terrorised kids and shook them down for their lunch money but were defended by school officials because of a winning sports season. Why are people persisting to apply cures to the symptons and not the causes of problems.
Hopefully this is not too offtopic, but how do you find such a job in the first place? Are most of the positions internet related or can just a hard core C/C++/Java programmer get them?
My experience with this was a year or two ago but they did have an utility that did swap out EBCDIC and replace it with ASCII. I was also using java and did not have to recompile the code, just use their utility.
Irronically enough, I do remember reading in Dr. Dobbs Journal that it was IBM that invented (or caused to come into existance) ASCII but they didn't inform the system programmers to switch their messages and thus lost the window of opportunity to switch from EBCDIC to ASCII.
The real question about this is why? OpenEdition (one of the newer OS upgrades) has a unix shell and all of the same functionality as you would find on a unix platform. Its not AIX and perhaps might not have as fast of a response time as the Linux box sitting on your desktop (but remember the strength of a mainframe lies in Volumn - processing large amounts of data not small amounts quickly), but it is still a UNIX shell. And no need to learn COBOL - java works just fine on it : )
One problem is that people do not understand that a mainframe is like a beowulf cluster in that it is composed of multiple computers but in a mainframe the different computers are optimized for specific processes (like I/O). Considering that computers are a human artifact and that like most things created by man, they get more refine with time and usage, mainframes have evolved and solved isssues that PCs haven't yet even hit because they have been around 40+ years.
A posse has to be organized not just thrown together. As LinuxOne could be a blemish to the OpenSource community, I think we do need to respond to the LinuxOne issue. But please, I beg people, an organized well thought out plan with good leadership should be the correct way to handle this instead of getting out the torches and pitchforks and storming Frankensteins castle.
Having read the Littman book on Kevin's story, the two questions that come to mind are: 1) Can anyone seperate the myth from factuality and tell me what he really was held in prison for? 2) Why was he painted by the media as being so dangerous?
Earlier/. posted an article about several ten commandments of calling tech support and for tech support people. Every commandment seemed to be a common sense idea (such as be near your computer with it turned on and ready before calling tech support). Now as long as people don't use common sense, I think everybody should make fun of them. I think User Friendly is extremely funny because of how close it does come to situations I have personally. Besides, laughing at people who don't use common sense has a long history. (Come on isn't that what makes the three stooges so funny?) experienced.
Divine Intervention! While I will admit that the two coasts do get a larger piece of the venture capital funds, Chicago now has DI (owned by former Platinum Technology chief Flip) which is doing its utmost to make Chicago a tech hub. And its only getting easier in Chicago due to newer tech hubs developing in the city and suburbs. Beside, isn't the largest beowulf cluster (Chuba City)located just outside the city at argonne national labs?
I am a NSV (Not Silicon Valley) programmer and a former employeer told me "it was not in his best interest in letting me get married because my productivity might slip" (meanwhile he's banging his secretary and a QA person on the side). Trust me, its hard to have any kind of life at 320 hours a month.

That is one of the reasons that I quit, actually.
