mainframes are not PCs

a. b. I don't have a truck to drive into my normal case to make it look like that
c. I couldn't get that piece of shit into my house

Damn IBM makes some good shit

WTF is that

just how strong are these ibm mainframes anyway? let's say you have an airline and you're keeping track of all your flights, inventory, etc, is one machine enough or do they have several of them?

IBM mainframe

Those are not about speed but reliability. IBM has never released any benches but people are guessing that with 5+ GHz and over 250mb cache per cpu not very fast.

SCALE
I NEED SCALE

I work on Z13s at work.
They're about performance AND reliability - and more importantly, scalability.

The Z13 chips are 5GHz, 8-core processors. Each system can hold 20 of these chips.
So you buy a Z13, then when you need to scale up, you just buy a new chip, more memory, and install it.

Are they good ?
Also can you ssh to it and post screenfetch?

>Are they good ?
If you're processing a ton of data, yes.
But they have a lot of drawbacks - namely, it's hard to find qualified people to work on them.
Finding someone with 10 years as a Linux/RedHat sysadmin is easy. Finding someone comparably qualified with ZOS is a lot more difficult.

>Also can you ssh to it and post screenfetch?
I'm a programmer, not a sysadmin, so I don't have constant access to it.

This needs to happen

imagine moshe's face

because I don't care if my server is picked up by radar.

I've felt like shit today; this post made me laugh a lot harder than it really should have.

Thanks, user.

fucking ugly

I'm not a bank or hospital.

I don't have a desktop PC since 2005. Laptops only, bruh.

What should I learn to program mainframes?

I am not a show off

OP never said that, he asked why you're not using a System z chassis for your PC components.

It's a mainframe and it doesn't conform to any standards existing in the PC world. Are you daft?

COBOL and Java.
A lot of places are still running and maintaining COBOL.
A lot of places are rewriting their COBOL to Java.
Everybody writes their new applications in Java.

I never said it was a good idea

Any advice or book that you would recommend?

"Java in a Nutshell" is my personal favorite book on Java.
I haven't read any books on COBOL, so I can't really recommend one. The syntax is almost English, so it's not terrible to read.

A good book on algorithms and data structures. Study memory management and concurrency.
Businesses have mainframes because whatever they're doing is super fucking important, and it needs to be efficient.
It doesn't matter how powerful the equipment is, if you write shit code, it'll run like shit.

Thanks

I know that feel. hang in there bro- it gets better.

Oh but I have

someone hasn't worked for a defense contract
literally crash cray machines back in the day
literally write shit code cause muh clearance and unlimited black budget
