I would be happy if I was good enough to submit a patch that caused Linus to be rude to me - if it was really terrible, he would ignore it - if it was spot on, he would simply put it in the next kernel.
Java is fine for heavy number crunching, so long as you program accordingly.
The JIT (Just-in-Time Java Compiler) that is part the JRE (Java Runtime Environment) JVM (Java Virtual Machine) is quite vicious at run time optimisation. Using the usage profile at run time, it compiles frequently used code into optimised machine code. It will even in-line methods calls that are at the end of long pointer chains (or more formally: at the end of a chain of object references)!
Java has facilities for using multiple cores for parallel execution, essential for effective concurrent programming. The JVM can also effectively use gobs of memory, using a Terrabyte is not unheard of.
If you are doing heavy number crunching: deal directly in double & int primitives, and avoid doing arithmetic using classes like Double, Integer, & BigDecimal - or unboxing & boxing will kill your performance. Sensible algorithms and other appropriate coding practices, are also needed for good performance, as well as choosing good libraries for heavy lifting in things like matrix operations.
Java also scales well in terms of complicated logic that needs to programmed by teams of people, in a way that is relatively easy to maintain.
I find Java the best language for most of what I want to do, though there are several aspects that cause me a lot of frustration, and (to my mind) unnecessary work.
No language is perfect, chose one that is best overall for your situation!
If you subscribe to JBoss from Red Hat for your enterprise Java needs, you will get very good support - for a lot less than Oracle is likely to charge. see: http://www.jboss.org/
There is a very active community for supporting OpenJdk, which is the code base for Oracle's Java offering. see: http://openjdk.java.net/
Java Enterprise Edition 7, has support for web sockets & HTML5, and many other related goodies.
Version 8 of the open source AppServer WildFly (JBoss community driven version), should be production ready before the end of the year: http://wildfly.org/
They will still keep the platinum second - but it won't need as much cleaning, as it will not have to be brought out so often for calibration purposes...
America has problems with its 'democracy', quite horrifying - especially as it claims to be the leader of the 'free' world!
Both China & America spy extensively on their own citizens and practice censorship, although the American forms are normally more subtle - neither is 'free' & 'democratic'. Possible the Americans are more hypocritical?

If we really want a sustainable presence on Mars, we have no choice but to obtain at least bulk materials from the Moon - such as fuel & shielding - later more refined structural components.
In the longer term we will need to be able to manufacture Hi-Tech stuff off Earth, but that will take a while - but we need to start NOW!
The fastest way to get a human on Mars is to launch from Earth.
The fastest way to get a sustainable human presence on Mars is to build a base on the Moon, and use its raw materials for shielding, fuel, etc., and only getting the hi-tech & wet-ware from Earth. Why lift a lot of mass off the Earth when it is is a lot cheaper to do so from the Moon, in the medium to longer term?
It is only cheaper from Earth for a one-off mission, or at most a small number of Mars missions.
For sustainable transport between the Earth and the Moon, you want at least 5 structures, 4 of which would be easy to reuse - in order to minimise cost: (1) Earth-LEO shuttle - the most difficult to reuse (2) LEO station - for transfer of men & material (3) LEO-LMO shuttle (4) LMO station - for transfer of men & material (5) Moon-LMO shuttle
LEO: Low Earth Orbit LMO: Low Moon Orbit
Similar reasoning applies to Moon-Mars transport, as there is no point in landing a craft capable of going between the Moon & Mars on the surface of Mars, or the Moon for that matter - though the Mars landing is the most technically challenging.
Obviously you have no clue about his workload, competence, effective leadership, his genuinely caring nature, nor his wonderful sense of humour.
I having been reading stuff he has written and seen videos of him over a period of 20 years - I would love to have him as a friend, colleague, or manager!
I think either you are very superficial, and/or a paid Microsoft troll.
You are truly clueless - I've just read what he actually said, he was actually giving a very mild rebuke in a humours way - and considering the situation, he was more than justified to be harsher!
You obviously don't appreciate his sense of humour.
If you think he puts other people down, he can do worse to himself. I remember reading emails years ago when he released a kernel update saying in very picturesque language that he stuffed up the previous release.
He has also found being polite, can be worse for people.
I wish I was good enough for him to insult me! However, I am not a kernel hacker, so fat chance.
If someone sends a patch which is terrible from an unknown, he is likely just to ignore it, but a good patch that did the job would go into the kernel with no fuss. If someone competent sends in a patch he doesn't like, with something he thinks is really bad, he will say so in no uncertain terms.
I have been reading what he has written and seeing videos of him, from time to time for over 20 years, so I understand where he is coming from and have immense respect for him.
He is neither a smarmy politician or a hypocritical religious evangelist - he is extremely honest, competent, & caring. Don't judge him by such superficial considerations that you seem to use.
When I went looking on Google, I saw lots of stuff about running Linux on the wii, but the following is the only thing I found about the wii running Linux as delivered!
About 6 years ago, I was meant to use Microsoft Office at work on a Microsoft box, but I found it easier to use OpenOffice. No one complained that they couldn't read my documents, nor about anything other than possibly the content.
My mother who is in her 80's finds LibreOffice easier to use than Microsoft Office.
Well I have used them, and know several people happy with them!
You obviously have not used a Microsoft O/S much, or you would know how difficult they are to use, let alone how insecure they are. I lost 4 full days due to malware, in a place were Microsoft boxen were setup by a special technical group. I've never lost time due to malware, when I've used Linux.
There is no one O/S that is best in all situations, if you prefer Microsoft, then go for it - just don't go claiming it is better than Linux.
I can do things in Linux, I would not attempt on Microsoft boxen, probably you can say the same in the opposite direction.
But not Microsoft currently only dominates the desktop, it has lost out in the mobile, embedded, and server markets.
Have you looked at Gnumeric (built by people who do some very fancy financial analysis, MIcrosofts Excel was too inaccurate - I read an in depth assessment by a maths professor, some of the mathematical functions he compared I had not heard of, and I've done stage III university Math!).
But a lot depends on how you use spreadsheets.
For what _I_ do, Linux is far superior to anything Microsoft has to offer, and I don't need to worry about viruses. When I was forced to use Microsoft in one company, I lost 4 full days of work (over a 2 year contract) due to malware, and the anti-virus slowed things down to a crawl. Java development can be done on either, but Linux is better suited - having 16 or more virtual desktops is a great way to organise your work, especially as I often stay logged in for more than 10 days at a time (9 & 21 days for the 2 Linux desktops in my office at home).
Well I don't spend much time playing games. It is much more fun writing software, and I get paid to do that. I've done it using various Microsoft O/S's, I've also used mainframes, minicomputers, Atari, Commodore, Amega, Apple, and various Acorn computers (the BBC model B was my favourite! - 6502 8bit 32KB ran BASIC 5 times faster than an Apple II) - I've missed a few. My first paid work was to use FORTRAN IV on a minicomputer, later COBOL on a mainframe, now Java on Linux. The first micro computer I used, ran MS-DOS.
Professionally, and also out of interest, I keep an eye on a lot of different computing platforms. My least favourite are those from Apple & Microsoft.
Embedded systems (including eBooks & smart TV's), mobile devices (tablets & phones included), servers, and supercomputers, are dominated by Linux & Apple (but mainly by Linux). Microsoft still dominates the desktop, but its market share there is decreasing. My current & previous jobs involved using Linux desktops.
How about growing up and realizing the world no longer revolves around Microsoft!
If you call me a rabid Linux fanboy, I suppose you should be called a Rabid Microsoft fanboy?:-)
I spend about 8 to 12 hours in front of a computer most days, so using an O/S that suits _MY_ style of working is important, so I use Linux - if a Microsoft O/S suits you, then so be it.
GNOME 3 is putting fashion ahead of functionality, try mate on Linux:http://mate-desktop.org

No problems.

A few months ago, I had a ten year old boy phone me up, to ask me to coach him in Java programming - his choice of language.
His parents are pleased with his progress, and so am I.
My own youngest some did a little bit of HTML, Java, & SQL at a younger age. He is now 15, and has since moved on to other things.
Both youngsters are in top classes and doing well at school.
People often grossly underestimate what young children can achieve.

the Postgres database is free & sufficient for a lot of enterprise work...
Eclipse is a very good free IDE, that runs on Linux as well as other Operating Systems (including those peddled by Microsoft)
Linux is free and powers most servers
most mobile devices use Linux
The need for Microsoft software is declining!
Microsoft is finding new ways of encouraging Developers to leave them.
