How is credit card made?

So how does it do that? Is it running a single program or is there some kind of mini-OS on it?

Your question is a bit vague; you should first define exactly what you mean by OS, otherwise I might argue that an OS is a "single program running on bare metal".

Interior please. #linux

thank you.

Just quoting the OP because nobody did it yet.
The first sentence (bolded) does not make any sense to me.
Throw in a buzzword (or buzz name in this case), you're on the road to nowhere.

1. No, that's not how things are.
2. How's that communism anyhow? Rather the opposite.

All in all, I'm thankful that you, bkbyon, took the time to formulate the longest post yet.

Nevertheless, all I can do is point you to the "Impossible Question" in the Help Vampire article in my signature.

Jethro's link in #32 is very useful if you can read it. I was not able to do so in firefox because of a blocking window that had no visible close button. If anyone else has the same problem, just use links instead.

This entire thread is a troll thread, I'm amazed it got to page 3 before someone posted the help vampire image.

This thread should be marked as solved then.

"Good luck with that"
