Meh.
I worked on mainframes for years and cheered when minis came along.
I worked on minis for years and cheered when PC's came along.
I worked on DOS for years and wept when Windows came along.
I worked on windows for years and sang choruses of joy when Linux came along.
I haven't moved off Linux because it just keeps getting better and better.
Would I recommend anyone go back off Linux to ye olde mainframes?
Not on yer Nelly. Never.
- slavapestov 7y agoBy "mainframe environment" the author of the article is presumably referring to IBM's zOS. Unlike minicomputers, DOS, etc, it's been continuously developed and improved over time. Other than using weird terminology for everything that comes from not being Unix-derived, nowadays it's a modern server OS.
- rbanffy 7y agoIt's fun when the terminology indicates some things used to be accomplished by reading decks of cards.
- Fomite 7y agoThe 'cards' statement is SAS remains one of my favorite ways to bring data into a program for exactly that reason.
- ndespres 7y agoThis isn't solely a mainframe thing. The pty/tty designation for terminals on Linux is a reference to when the computer had no display, but output to a typewriter (to give one such example).
- majewsky 7y agoAlso, tar is short for "tape archive".
- whatshisface 7y agoTape archives were actually cost-effective right up until a few years ago.
- DrScump 7y agoused to be being the relevant metric. Linux and UNIX used to be installed using stacks of diskettes and piles of patience.
- rbanffy 7y agoI once booted from a DAT tape.
- southern_cross 7y agoOpen a terminal session on pretty much any platform. If it defaults to being 80 columns wide, guess where that width comes from.
- fooker 7y agoWhere can I find a nice article about the design and the terminology?
- ianai 7y agoProbably a proprietary, expensive training course.
- southern_cross 7y agoPretty much all of the related documentation is publicly available, AFAIK, and freely accessible on the internet from what I can tell. This availabilty is actually a legal requirement from times past, IIRC.

- wyclif 7y agoMy cousin recently went to a weeks-long class and got zOS certified. He's been a sysadmin at a university for years, and they don't use zOS there at all. But I think he did it just to learn the system and have some career insurance. I was fascinated that people are doing this.
