Re-install/re-image, effectively the same thing in this context.
An upgrade trashing all of
The newest fun here is that Windows 7, even when sysprepped, will still occasionally barf when cloned to a computer with different hardware. An operation that is trivial in nearly every Linux-based configuration.
You'll have to wait for the next "average Linux user" there, sonny. I have been doing system administration for two decades and have seen Linux systems, yes both rpm and deb based, badly messed up from updates. Some have required several hours work to get back running again. But, repeating myself, nothing that has required a complete reinstall. And it has been several years since I have seen an update require more than a few minutes work post-install.
It's undeniable that dams have a significant environmental impact. However these are a one-off expense, an overhead. They are not dependent on the amount of energy produced so while it gives *some* argument against building new dams, existing ones should be maintained and upgraded so they can generate as much power as possible with effectively zero environmental impact per GW. or diminishing impact per GW if you factor the overheads over time.
Funnily enough I saw an article yesterday about a fish cannon, purportedly to send fish over dams to spawning areas.
I have never seen a Linux distribution where one botched update has resulted in the need to completely wipe and re-install the operating system from media.
I have seen this with Windows 7 and 8.
I have seen this to a lesser extent with Windows XP, but that at least still has the option to re-install system files without affecting the user/program environment. Not so with Windows 7 or 8.
Windows 8 has some nice recovery tools, but they are buggy as all buggery and just as likely to render your system even less usable.
And, or course, the fact that the phone was bricked for no reason. Also, the video will be recoverable.
If video is recoverable then the bricking process is defective.
I don't think they are talking about putting a button in every police car that bricks phones.
Not yet they're not.
Who actually wants a kill switch? Anyone on
This anti-feature will be used by not just government but any suffiently motivated hackers to kill your communications. The one ostensible benefit mentioned here is anti-theft, but of course that relies on the mechanism working reliably in the first place and secondly not being circumvented by a thief five minutes after they have acquired it.
Just like the idiotic remote car immobilisers that people who should know better are so quick to adopt. Just wait until some hacker gets the code to your car and holds it to ransom or worse, immobilises it on a freeway. What about when overzealous local law enforcement decides to immobilise all cars exceeding the limit by 1%.
Hi Smidge,
Do you object to such claims because you believe them to be incorrect, or just pedantic and unhelpful?
I'm with you on the second point although I do bring it up as a logical conclusion when someone tries to distinguish between generating and storing energy, since most energy generated on Earth in turn comes from the sun.
Fair enough, but if you carry that logic far enough then fossil fuels aren't an energy source either. They're temporary storage for the sun's fusion energy.
Wind power is also solar. So are fossil fuels.
To move further up the pedantry scale, all solar energy is also nuclear.
Enjoy your fusion-powered car.
Correct. To be even more pedantic you could say it's nuclear power just like every other energy system on Earth other than the odd zero-point experiment producing a few femtowatts in a laboratory..
However you can consider that gravitational potential energy as an enormous buffer, since there is absolutely no correlation between hours of sunshine and hours of available energy from the system. There's also nothing mandating that the dam has to be filled by precipitation - dams employing pumps exist.
Clearly it's the rare but apparently also invasive comma-fish, often abbreviated as the ,
Gravity, from water in upstream catchment areas and falling from the sky as rain both into the catchment areas and directly into the dam.
How did the water get "up" in the first place? Well that's solar energy if you really want to get down to it which is, in turn, of course nuclear.
I'm not really sure what answer you're looking for there.
Gravitational potential energy cannot be used as an energy source.
Several hundred million people who use hydroelectric dams as their primary power source disagree.
Still not enough for the Mythbusters.
(On a more serious note though, how on Earth do they manage to store even a few microseconds of the footage from this beast?)
I haven't seen any of the articles, but I'm guessing the news about it has been spread in this fashion:
Rocket companies hate this. NASA has built a new type of engine using a simple trick. You will NEVER believe what happened when they switched it on. When I saw it, my mind was blown!
