Nobody said Java was better for those applications. Just that it's extremely widely used there, along with Linux - and based on my experience I'd tend to agree.
You'll lose that bet. I keep my Hotmail address as quiet as possible (in particular it isn't mentioned on any web pages that I know of), and haven't had a single piece of spam there yet (unless you count mail from Hotmail, that is...)
Ironic, really, since WineX makes Ports less likely...

Java Faster Than C++?

If that's the approach you're going to take, though, then you might as well just code in assembly - cut out the middle man. Benchmarks like this are entirely worthless - the main thing they do is stir up the rabid language zealots out there, 5% of whom will be crying from the rooftops that it's all a lie and C++ is better, 2% of whom will be insisting that the results cast Java in a bad light and that it should be seventeen times faster than C++, the other 93% will be pimping their own language of choice.
At the end of the day, the real question that I should be asking myself is which language gives me the best balance of maintainability, ease of development and elegance of expression. I don't care if you can shave two instructions from your generated assembly code at the cost of making your code ugly as hell and impossible to maintain. This is a bad trade-off that only matters to the most anal of benchmarkers and those rare few who really do need the absolute maximum performance from a (typically small) segment of their code. I want to know which language is going to make me most productive, and there's no objective measure of that which I trust as far as I can throw it.
I seem to remember that you could not start doing even simple input in Java without covering exception handling.
This is true - as a result, in our beginner Java courses we covered exception handling fairly early and I/O fairly late.
If you want to use I/O earlier, then the obvious solution is to create an I/O class that beginners can use with a series of simple methods for reading in data (text, numbers, whatever) that traps exceptions internally. Then you can move them on to the right way of doing things once they're familiar with exceptions. You can probably find any number of these available online, or write one yourself in a couple of minutes.
I find Java to be far from ideal for beginners, and I'm largely a fan of the language (and have been working as a Java developer and trainer for the last six years or so, including teaching it to complete beginners with varying degrees of success...) There's so much that you have to do just because before you can start writing code. Not to mention the complexity of the actual process of compiling and launching the code.
I'd much prefer a purely interpreted language that can give immediate feedback as you enter your commands. Oh for the good old days of BBC BASIC...
There's no disable-ware on Mandrake that I've ever come across. I'm currently unable to join the club, and I'm able to run a full version of 9.2 at home.
I remember reading about converting 2D movies to 3D when I was at primary school. Since then I've been through secondary school, two university courses and two jobs, and I'm still no closer to being able to watch the things.
Still, I look forward to being able to read ten years down the line about an amazing new device that can display current 2D movies in 3D.
To correct some of the misconceptions, though, it's the GS that's handed its ass by ATI and nVidia, not the EE. Sony's record for designing things with developer considerations is actually pretty good - witness the original PSX, and the changes they've made to the hardware spec of the PSP to satisfy developer requirements. I'll let the 'PS2 is a nightmare to code for' comment slide, because I don't have any experience of it myself, but I know a few people who don't find it much of a problem...
Depends. I use a partial number-for-letter replacement system in my passwords, but I don't use the standard translation system you describe above. As a trivial example of how you might use a non-standard mapping, how about this one - substitute each letter with the number that appears at the top of the diagonal row it maps to on the keyboard, so that qaz are 1, wsx are 2, edc are 3 and so on. Pick a pattern for which letters to substitute, (or substitute the letters in your mnemonic phrase that you think should be emphasised if you're going for that little bit more security). Got that in your dictionary attack? I hope you've got the equivalent for reading the rows the other way (esz to 4, rdx to 5 and so on). Both easy for any user to work with, because the translation is right in front of you on the keyboard. And there are countless other techniques available, especially for those of us who can remember what order the letters come in.:)
Even if you're just using the standard l33t-5p34k translations, you're massively boosting the number of checks that need to be made. Your examples didn't change all the letters that could have been changed. So now as well as security I need to check 5ecurity, 53curity, 5ecur1ty, 53cur1ty, and doubtless others. That's a substantial increase in the size of my dictionary...
It's not quite as neat, though. Hydra had many heads, Shiva had many ARMs. The videogaming geek in me is desperate to suggest Goro as an alternate name if Shiva was already gone.:)
Ah, brings back memories of the Hydra processor board for the Risc PC (which was never actually available, was it?) - I always felt Shiva would have been a more appropriate name, though, for obvious reasons...

Apologies for any errors - my technical Russian's a little rusty.:)
That's nice for you. I've tried (and been using) OOffice for over a year now both at home and at work, and it has met my requirements perfectly adequately. For some of that time I used it alongside MS Office, and I found in a number of cases that OO handled large documents (particularly page numbering and footers in those documents, coincidentally) better than MS Office.
I guess we've had different experiences of the software, but in my experience, for the uses I've put it to, OO has been the better package, and if the price on both packages were the same I wouldn't hesitate to choose OO over MS Office.
I see that process as more likely to work the other way round, and I'm sure I've seen cases of this reported on Slashdot and elsewhere - OpenOffice (sorry, OSOffice) running under Windows is the first step towards change - when the application software has been gradually phased over to open source, there's no point in paying the premium for Windows licenses when there's no software left that requires Windows to run.
To what extent do you believe Windows binary compatibility on Linux could stifle development of native Linux solutions that compete with those Windows applications?

A better reason to learn ARM assembly would be that it's actually really rather pleasant. Very simple, very consistent, very powerful.
Nobody said Java was better for those applications. Just that it's extremely widely used there, along with Linux - and based on my experience I'd tend to agree.

Unfortunately, the price is in dollars, not yen.

The site does mention this, and says that where there are conflicts, repeated information takes precedence over one-offs.
Try removing the crack-smoking package.

Insightful? Well, whatever floats your boat.

Yes. It's a nice operating system you've got there. Be a shame if anything were to happen to it.

Personally I take offence at your narrow typecasting of Slashdot users.
Some of us use wireless mice, and would have to resort to hanging ourselves with VGA cables.
