In my experience, in a modern server PHP uses more CPU than Java. You might be right about slow machines though. I don't understand why you make such a big deal about servlets vs jsp, as jsp is just a technology to ease the construction of servlets (every jsp gets converted into a servlet)... And I don't agree you can't compare PHP to Java, they try to serve the same purpose.
Some time ago I *had* to work with PHP. I haven't known it before that. Now I hate it =). At that time I wrote a comparison, out of anger about PHP being so much used. This is the comparison Java - PHP I have wrote.
The standard desktop is better than Google desktop. Yes, everybody says, to put Google in a good light: "standard compliant" browsers, but that means nonstandard compliant mail, nonstandard everything else. We won't own software, we'll be always customers, dumb terminals, served from huge company's "clouds". Free software will be over, irrelevant. We won't be able to improve and modify our environment, we can't improve Gmail ourselves, there's no alternative/better/innnovative client for Gmail.
Economic forces are taking technology down a terrible path. The past is better: a world of protocols, servers and clients. A common neutral space...
The "portable" desktop, having your data everywhere should be solved by other means... I don't know, perhaps we should have personal servers, or at least we should contract personal servers from some kind of "personal server providers", which should be a standard and non-monopolistic thing. The "presence providers" envisioned by the XMPP protocol comes to mind...
There's no need. There are no segementation faults in Java. There's no way you can access memory you don't own. And then, any error just provokes an exception, which can be catched.
You are right that Java model help with the need of having finer-grain-than-a-process security. It's partly because it was made for applets. Java supports running safely completely untrusted code.
And your objection to "virtualness" can be replied with an analogy of C vs assembly language. In Java you loose control, but the VM gains control to optimize... just as in C, gcc usually knows more about how to optimize. And speed-wise Java is very good, is at most 2x slower than pure C (I think it's even faster), which is a great thing actually.
Java "machine code" targets an abstract CPU which can handle "objects", "methods". You can disassemble compiled Java code and you see "invokevirtual" which means "invoke a virtual method on an object".
Then, an object in Java is a fundamental thing, there's no way to "decompose" it. There no way of getting its memory image. This has some nice properties:
The vm can reorder object fields to play nice with machine's alignment.
Security, you only can access the objects you have been given to. There's no pointer arithmetic. At all.
All objects know who they are, there are no undetected wrong casts (similar to the newer dynamic casts C++ now have)
Absurd, Marx was a "hit" well before any revolution happened. And there were lots of other "revolutionaries" in the XIX century that nobody care about now. Marx is relevant because the amazingly sharp analysis of capitalism.
What I say is it wasn't created for profit, it was created very far from the market. There were no MBAs involved, no managers. It was a community puting out software and RFCs. The corporate world, at that moment was busy creating zillions of incompatible little LANs, onthe low end, or a monstruosity (the ISO/OSI model... X.25) on the high end.
No. Sony isn't just a "media company". It's one of the big technology companies. And it's relevant that one of the biggest technology companies hate Internet.
Capitalism can't produce common goods. Internet would've never had existed if it weren't for the US government. It was created in an academic environment, by passionate people that cared about the advance of technolog (indirectly: of mankind). Internet advanced quickly, different protocols appeared, once replacing the other (Gopher, SMTP, HTTP, POP, IMAP, NNTP, etc.).
Then the companies came. Those set of protocols froze, some began to fade. Companies didn't care about "what's right". They didn't care about advance the network. The HTTP/1.0 -> 1.1 transition took years, and still hasn't finished (e.g. http pipelining). IMAP mail stalled, and got replaced by webmail. Multicast was never deployed at large. Newsgroups got replaced by phpbb.
These companies hate Internet. If they praise it, it's only when they realize they can't afford to ignore it (or destroy it).
You certainly don't sound like you know. Saying "trust me, it was my minor" is not very interesring or useful... The US has a history of messing with LA, an History other countries don't have. Nnot only private companies, but the CIA itself had participated in many LA tragedies. Go read a bit about this, very interesting.
Your message might look "Intereseing" to the Latin America history ignorant. The truth is that most of the time the money go to foreign companies, based on countries like yours.
The big question is if Oracle will keep being Oracle. This company has swallowed something bigger than him. Oracle might be more firmly sat on top of a revenue generator product, but Sun is a much larger operation, involving a dektop presence pretention, mobile, high end hardware design, high end software (Solaris), etc. (That's a reason IBM was a less conflicting buyer for Sun). In turn, Oracle sells a databse, and some enterprise programming tools, they have a much narrower scope (even the name implies this focus).
Perhaps, Oracle should rename themselves to Sun, and just sell a database called Oracle. =)
This "purpose of the bible" is a new thing. That wasn't the idea of religious people until the last few centuries. As long as science advanced, there was no other choice than fall back... And if that's the purpose of the Bible... why does it leaves so much to interpretation. According to what passage we choouse we could think that it's asking us to kill all homosexuals, or to love everybody, or that jews who don't believe in Jesus are "sons of their father the devil"....
Besides, the bible does describe in detail the creation of our world. And it tells a story that, as I said in my first message, is wrong even as a metaphor.
Christianism is really incompatible with science. In that regard, I think the real fanatics are the real honest here. Accepting both science and the birth of Jesus from a Virgin is having a big unsolved puzzled in your head, and trying hard not to ever solve it.
Evolution is compatible with your believes because you are inconsistent in them, and you choose to randomly accept or reject parts of "The Book" so as to not challenge "your believes". According to the Bible god himself created all animals at once, and presented them to Adam so that he would name them. That implies that all animals were there when the first human walked on earth, and implies that animals are separate creations. And this is only a sample of the incompatibilities...
It doesn't work like that. The kernel never uses its own filesystems' support to load itself... How could it if it hasn't been loaded yet? That's the job of a "boot loader". The most user boot loader currently is Grub, and previously was Lilo.
Grub supports some filesystems, so it can access them and load the kernel. Lilo did not support filesystem, so there was a tool that you needed to run each time you changed the kernel. That tool built a list of blocks, so that Lilo could load the kernel (from those blocks) without really understanding the filesystem.
3rd party program have installed plugins/extensions for ever...! This reminds me of a story by Asimov in which a man discovers he has something called a "skeleton" inside him. He is worried, because this thing is obviously against him. He consults a weird doctor to get this skeleton removed from him... So shut up, you, hypochrondriac computer users!

... so... wouldn't it be the same just putting your data in the body of an ICMP echo message (ping)?

Ask in Bolivia if they have forgotten.
You should read a bit about history of Latin America =). Just one example: http://en.wikipedia.org/wiki/Banana_massacre (there are more)
Of course, Bolivia doesn't have access to ocean ports because Chile took Bolivian coast by force.

And I thought the only nazis here were grammar related...
I would say that a monopoly of one is better than a monopoly of zero...

Interesting! But... what about localized builds? I like my Spanish speaking Firefox...
Couldn't they provide 64bit binaries? That would be very useful, at least to me...
Which in turn sounds pretty similar to... Java!
