Comment Re:Sort of dumb. (Score 2) 553

The hardware knowledge argument has become virtually irrelevant in the EC2-world where you can spawn VM pretty much transparently

Right, we forgot, Amazon VMs are magical devices powered by hopes and dreams, rather than CPU cycles like old fashioned "computers" are.

Back here in reality cloud virtual machines are just a shitty containment mechanism that's sort of like an operating system process, only dramatically less efficient. Did you know that Google, not a company exactly famous for lacking clue, doesn't use VMs internally at all? Every internal program runs as a regular operating system process on top of a patched Linux kernel. The system is called Borg and they published a paper on it recently.

Why don't they use VMs, Amazon style? Because VMs suck. Running an entire OS inside another OS just to provide isolation is a great way to waste vast amounts of money and resources. It means sysadmins get to reuse their existing skillset instead of learning some new way of managing software, but that's about it as far as advantages are concerned.

Certainly your Amazon VM will suffer from cache line interference, limited resources, and other things that plague physical devices.

Hardly. AirBnb and PayPal are both good examples of this sort of thing. PayPal got raided a lot and got sent C&D letters by various state regulators when they were rolling out across the USA. Eventually they had to sell to eBay (their primary competitor) to get enough money and political immunity to survive. There's a book about it called the PayPal Wars that goes into more detail on this.

Comment Re: Why is is the material support provision bad? (Score 1) 121

lol. This is an administration that defines the word "militant" as meaning any male that isn't a child or pensioner. "Material support for terrorism" doesn't mean anything at all, given that the last 15 years have shown governments will happily label anything they don't like as terrorism. Bear in mind the primary roadblock that prevents the UN agreeing on a definition of terrorism is western nations (i.e. America's) insistence that people who resist foreign occupation of their countries must be considered terrorists, and Arab nations insistence that they mustn't.

OK, I will try to restate in my baby talk since I don't remember this correctly.

Given that you are accelerating, the appearance to you is that you are doing so linearly, and time dilation is happening to you. It could appear to you that you reach your destination in a very short time, much shorter than light would allow. To the outside observer, however, time passes at a different rate and you never achieve light speed.

Comment Where we need to get to call this real (Score 1) 480

Before we call this real, we need to put one on some object in orbit, leave it in continuous operation, and use it to raise the orbit by a measurable amount large enough that there would not be argument regarding where it came from. The Space Station would be just fine. It has power for experiments that is probably sufficient and it has a continuing problem of needing to raise its orbit.

And believe me, if this raises the orbit of the Space Station they aren't going to want to disconnect it after the experiment. We spend a tremendous amount of money to get additional Delta-V to that thing, and it comes down if we don't.

With some optimism that might only be thousands of years rather than hundreds of Millions.

But it's only necessary for Earth to be uninhabitable for a short time to end the Human race. And that can happen due to man or nature, today. If people aren't somewhere else during that process, that's the end.

Obviously I am missing something, then. Please fill me in on your better information sources. Email to bruce at perens dot com if you don't want to put them on Slashdot.

It's time to start planning another trip to Lompoc. The Motel 6 was sort of yukky last time. Maybe I'll try something else. There was an official visitor observation site that I found and got into last time, but that was for the Delta, and it was on Pad 4 if I remember correctly. This one is all the way on the other side of the base on Pad 7 or 8, isn't it? There are some farm roads that might be good observation sites if they are open.

I am not confident that the world will remain a hospitable place for life until we are ready by your standard.

Getting the resources and people there is very close to being within our technical capability. The task ourselves, if we perform it, will take care of the remaining gaps.

Creating a self-sustaining colony outside of the Earth's environment is going to need a lot of work, but it is not work that can ever be achieved on this earth. We have to actually put people in space to achieve this. Our best experience so far is with submarines. Academic research has so far yielded only farcial frauds like Biosphere II.
