The whole area that the ISP (or atleast the one that owns the infrastructure like the cable company) has needs to be densely populated, because otherwise rural areas need to be compensated ?
Do you think HTML5 would have existed without Mozilla.
It was Mozilla and Opera that started the WHATWG which started the work on HTML5.
Now all major browsers (IE9, Opera, Firefox, Chromium/Chrome, Safari) support large parts of the HTML5 and related specifications and are working on adding more support each release they do.
I think if people only see news about iPhone first-smartphone-with-app-x then that is a probably not good, this news might help to balance that view a little.
1. because things can conflict, for example I heared it isn't smart to install Exchange on your AD/domain controller (don't know why, just what I heared). 2. because of single point of failure and when problems arise, you can reboot one thing without affecting others
I assume ESX saves the state of the VM on the shared storage ?
The problem I see with that is that if the system crashes, you don't have the state at the time of the crash. At best you have the state that's very recent but is prior to the crash.
So you are creating a time warp for your application. I would be very careful with that.
Even the fastest methode of virtualisation is currently 10% slower for disk I/O than bare metal.
Many that have large setups with virtualisation and many databases, use shared bare metal database servers with replication or shared storage to make it HA.
I think SSD as a fast cache in front of HDD is still sounds like a great way to use them.
ZFS supports this, some RAID-array, some RAID-cards do this now and there are a number of other projects which try to do at the filesystem/OS layer like ZFS but those are not completely production ready for everyone/everything.

That was one of the questions I wanted to ask. So how open (source) is it now ?
I just know OpenJDK exists, I even know where to download it:
http://download.java.net/openjdk/jdk7/
Ten years ?
Yes, let's create more monopolies !
I'm not sure that is the solution. It could be, but have a lot of doubts.
I don't think many countries would consider that center-left.
That is a very densely populated area.
But having a 1 Gbps upload or almost any symmetric connection would be nice for a change.
I don't agree.

Sorry, I can't seem to find the article right now. Seems I didn't bookmark it.
But it was from earlier this year and an article similair the one below, but with bare metal as comparison as well.

I think he means:
A company like Amazon which people used to think is a books-company thus mostly about 'real world' things is actually a software company.
They create their software to be more efficient at what they do than their competition, thus more profitable.
OpenVZ already supports Live Migration, Virtualisation is just overhead.
Jobs ? Like processes ? OpenVZ can do live-migration and the kernel hackers are working on checkpoint/restart of process trees.
1. because things can conflict, for example I heared it isn't smart to install Exchange on your AD/domain controller (don't know why, just what I heared).
2. because of single point of failure and when problems arise, you can reboot one thing without affecting others
and so on...
OpenVZ already has live migration.
You didn't even read the summary ? Or you don't know what FreeBSD jail, OpenVZ, LXC and others are ?
It is virtualisation at the operating system level. It is like a namespace for your process. Some of the variants even support live-migration.
Virtualisation like Xen, KVM and so on add a lot of overhead, it is less efficient than OS-level virtualisation.
Obviously you can't run IIS on Linux that way, but it doesn't use more hardware as you mentioned if it happends at a different level.
"It's really, really nice to be able to move a running Linux guest with a few hundred users over to another server without a hiccup."
OpenVZ and probably some others can do that too. You can migration 'containers' just fine.
I really hope LXC (Linux Containers) will get it too soon, so it is in the mainline kernel.
A 10% I/O performance hit (with virtualisation, with many variants it is a lot more) is not for everyone.

Or in JavaScript ;-)

Silicon is just sand, right ? That is hardly rare ;-)

More like a toolchest that only has one tool, the eyelash curler.
The iPad hardware could be used for a lot more things, if only Apple allowed it.
That is interresting, how would they do that ?
Maybe just for a country-level TLD like .de But not just any domain.
That is what DNSSEC is for.
But at the moment, no-one can garantee that if you are in a hotel network you can get that DNSSEC-information.
So it is hard to deploy at the moment, a good fallback-methode is needed to get it started.
euh.. no.
You just tell the user, like in any browser. Goto Help->About
Ofcourse you are able to version check.
It just is the user-visible number in the title-bar they are removing.
That is it, that is all.
