Which programming language should I learn?

[NotAllThere]

Has anyone used F# much?

I have, but only when doing something major in G. (Or for minor work in B).

Java always was and always will be a steaming pile of sh*t for anything other than very simple unimportant interfaces where there is very little data.

That's even less credible than your dodgy AGW arguments. Back-end web-based systems in many sectors are built on Java, including the banking infrastructure (apart from C++ used in some specialist areas).

Actually, I read an interesting paper in CACM the other month about that.

Basically it said that although it's possible in theory for a buyer to value one of these CDO even when they don't know to what extent the seller has stuffed it full of lemons, and hence in theory the seller would have no incentive to do so, in practice a computationally constrained buyer wouldn't be able to do so hence the sellers who realized this could get one over on the market and remain undetected while doing so.

I'm not a programmer but I was I'd learn machine code, I mean, how hard can it be to learn '1' and '0' - there, I just learned it...

Well I happen to know one or two banking apps, that were a mess becuase of Java, yes they get them working in the end, but a huge pointless amount of effort it trying to make them perform. So just because a lot of banks have gone through this pointless "buy a huge machine to make it work" doesn't change it's unsuitablility for hunky dunky servers. And if it's so good why do I have to wait half-an hour for the Sun java based C++ compiler to step along the code. Java was a big mistake, the cross platfom idea is utterly pointless. How many Java apps do you know that are actually working on multiple platforms?.

By "step along the code" do you mean you are stepping through in the debugger? In that case the reason it takes half an hour to get to the next line is because the last one took half an hour to do whatever it does. That is to say, it's your C++ code that's the problem.

Oh BTW I have written one server side java app that has been deployed on windows, linux, solaris & AIX, and a couple of others that have managed 2 platforms. I also have some utilities of my own that have seen action on several platforms. Oh, and eclipse I have used on several platforms as well. So it does happen.

I bet they were a mess because the developers didn't know what they were doing, or because Java was used in a performance critical app (trading perhaps), or because a very old crappy version was used a decade ago. I've also worked on banking back-end systems and they all worked very smoothly on a Java infrastructure.

Because that application was written by useless developers, I imagine. The speed difference between C++ and Java is typically a few %, but even if we said 100%, that would not cause the problems you see. Ergo, Java is not the problem here.

• The UML tool I use is 100% Java.
• Eclipse IDE is mostly Java as far as I can tell, and is the default IDE for Java development - and doesn't suffer the issue you describe.
• OpenFire & Tigase provide ability to run an IM server for 100k users on a single server
• SmartFox can let you have 10s of thousands of simultaneous players on a single low-end server

When did you last actually use Java, like version 1?

Type "Java App slow" in Google.

I rest my case.

[d000hg]

What exactly is your case? A lot of search results? in that case, search for "global warming". Or maybe you claim if enough people spread the same misinformation that makes it true?

This thread is eye-opening into your thought processes. Unlike AGW this is hard, measurable science where we don't have conflicting, unprovable models to support our claims. Modern JIT compilers are very quick - as evidenced by recent improvements in browser JS performance as well actually - and differences are down to a small margin.

I think you're just trolling.
