You're being ridiculous. I am an energy-efficiency wonk. You can build as many nuclear power plants as you want, as long as they can compete with other forms of clean energy on price.

Once we have switched to zero-carbon electricity or at least made polluting forms of energy pay appropriate taxes to offset the damage they do, you can use as much energy as you want. That is between you and your wallet. But until then, your electricity consumption is partially paid for by me. Do not waste MY money.

She brags about her security clearance and about how she knows so much about what is going on. She may not be all that bright, but surely given that information she could figure out why they needed the server capacity.

Her defence of waterboarding shows what a disgusting person she is. I am ashamed that I was working for HP at the time.

Even if Windows was a microkernel and TrueCrypt was running without privileges and so on, I think that many users use TrueCrypt to encrypt their system partition. Once TrueCrypt is compromised, the attacker can replace e.g. SVCHOST.EXE or another critical Windows system file with anything they want. I am not aware of any security technology which can stop an attacker who has broken the file system driver for the root file system. I am not sure what that kind of technology would even look like -- all the ideas I can think of are completely impractical.

The Danish grid as of today would work just fine if you cut all the international cables. This will not be the case in the future, but right now the power plants in Denmark would be able to stabilize the grid and provide sufficient power.

I can assure you that no pumped storage exists in Denmark. When electricity prices go negative (which happens a few times a year), the large wind turbines shut down. Some power is dumped as heat in large (many MW) electric boilers for district heating, and hopefully the installation of more electric boilers will virtually eliminate negative prices.

But anyway, pumped storage is not in any way fundamentally necessary for a functioning grid. It is certainly helpful, but when your tallest hill is 173m above sea level, pumped storage sucks.

Life is basically a way to export entropy elsewhere. Life uses low-entropy energy like sunlight and turns it into high-entropy energy like deep infrared in order to stay complex and low-entropy (unusual combination) itself.

The assumption is that if you have more efficient processes, you use them to do more useful work, not to sit around singing Kumbayah. I.e. efficiency increases are offset by increased consumption. This certainly seems like a reasonable assumption for life as we know it.

You do know that HughesNet is a satellite ISP, right? There is no viable business case for unlimited satellite internet at anything more than 9600bps or so. You are sharing a much-less-than-gigabit connection between tens of thousands of users to get the average price down enough to make it affordable. A typical user who transfers 100GB a month will ruin it for everyone.

I have seen quite a few impressive graphs where business DSL lines were filled to capacity for hours after the Windows 10 release. This is great news for most ISPs -- sure it means an extra cost of bandwidth short term, but it is going to put switching to fiber (or draconian QoS, more $$$) into the minds of many managers.

Satellite ISPs are going to lose out. They make a bit of money short term because of the bandwidth charges, but they will shed customers because most customers hate unexpected bills.

They may have correctly triaged the undisclosed bugs in terms of importance until disclosure forced less important bugs to a higher urgency.

They made the assumption that undisclosed bugs are unknown to blackhats. As the breach shows, that is a pretty bad assumption.

Basing importance on the disclosure status is a horrible policy, and the only effective antidote is immediate full disclosure without grace period.

The Fedora build of Firefox is certainly built from source. It is still called Firefox.

Fedora is discussing whether it is feasible to continue with Firefox-branded Firefox due to the new signed-addon policy. But for now, you can certainly get your open source Firefox fix that way.

There is _no_ fusion technology ever tested, nor realistically proposed that does not rely on tritium.

Polywell and others propose hydrogen-boron. As for realistic, the challenges are certainly different than for deuterium-tritium. Whether they are harder is difficult to say for sure until one of the technologies start actually producing electricity.

Comment Declare SSID's expensive (Score 4, Interesting) 194

When setting up an access point, it should be possible to designate it as "expensive", and by default devices should adhere to this and try to limit unnecessary data usage. I get annoyed when I use my phone as a hot spot and discover that my computer has fetched upgrades, my other phone has downloaded a bunch of podcasts, and so on. It would also allow me to keep a backup wireless SSID running permanently, knowing that the devices will go for the cheap SSID first.

I bet that quite a bit of bandwidth usage on planes is due to phones thinking they are switching from expensive (but actually dirt cheap) 3G/4G to cheap (but actually really expensive) wifi.
