Less dead than perl by far. I've seen a lot of new COBOL going into production just this year. New versions of the compiler (the IBM one, the only one that really matters for COBOL) are still being released. A while…
As somebody who likes it I think I would explain it along the lines of FreeBSD vs Linux. AIX is a complete package OS with some nice enterprise features, and it is modern and similar enough to make porting from Linux…
If POWER LPARs are the same as Z LPARs then a lot of it comes down to the difference in licensing between hard and soft partitioned VMs. On a typical VM Oracle will charge for the entire cost of the machine, even if the…
This is a key part of IBMs strategy, since it seems that LPARs on mainframes are treated as hard partitions and do not incur the same "whole machine" cost as VMs. At least that is what IBM themselves say when asked what…
I would recommend focusing on DB2 and Oracle rather than MSSQL if you are trying to learn about that. MSSQL is not particularly expensive in comparison and doesn't really try to compete in the big enterprise league.…
Which folks haven't mentioned yet, but z/OS is also a proprietary UNIX, albeit in a very strange way given that it is sorta like a subsystem/different way of looking at the same things, but is also in implemented in the…
I like it. The structure of the code you write looks much more similar to what you would write on a piece of paper than Haskell (for instance, getting rid of in, the pulling into scope at the top). Not to mention the…
The thing is, there aren't really any successful greenfield developments in these types of business spaces. So either these are industries that are exceptionally difficult to break into (which I think is at least…
