Because ubuntu dosen't allow new major versions to be added to a distro that has already been released.

Do they allow packages to be ranamed? Then changing only 5 bits woudl rectify the situation.

If they just leave the code as-is, but change the name from "ownCloud" to "pwnCloud", then the actual functionality of the package would be clear to everyone.

Wonder if the cashiers would even be able to do that today...

They weren't able to do it back then, either.

Any large order had an almost 100% chance of having an arithmetic error. It was always unfathomable to me how more than a century after the invention of the cash register, a multi-billion dollar company could predicate all of their income on high school students' scribbling. Not to mention having to wait in line while all these errors were tediously generated by the staff then checked over by irate customers.

It was a great thing when McDonalds finally dragged themselves into the 19th century.

Second, people can read signs even after revolutions. If you put "severe radiation, stay out" on a concrete building, it'll be fine.

An additional advantage to those signs is that in a dystopian future, the terrorists are usually the good guys. The info will help direct those good guys to where they can find materials helpful in the fight against evil governments.

It's not cheating if it's part of the strategy of the event. See also: NASCAR, speed skating, bicycle racing, etc. It just means that in addition to raw speed, the runner needs to effectively manage the interactions with other runners.

At any rate, this arbitrary milestone would have been achieved long ago if the wavelength of light emitted by exited caesium 133 atoms were only a tiny fraction of a percent longer.

I can't wait for to be woken at 5 AM when the turbine generator fires up outside my bedroom window ;(

The garbage trucks active at wee hours are usually emptying dumpsters. The engine noise is least of your worries compared to the sound of them slamming a half ton steel box up over the truck then down onto the pavement.

As a former weekly 3:00am victim of this practice at an apartment I used to rent, I think that operating any garbage truck between 11:00pm and 6:00am should be made into a felony.

Python? You serious? Bye bye one liners with for loops or anything else. I really doubt anyone wants to have pretty code enforced on them for something as simple as iterating through a few numbers one time, ever.

I was looking at LED replacement bulbs at the hardware store the other day ($20 each). I am suspect as to their efficiency.

Get a Kill-A-Watt meter and test the power consumption of LEDs youself. All the ones I've checked have used just about exactly what it says on the package.

They have large heat sinks on the which get very hot. That is wasted energy.

They have heat sinks because the LEDs need to stay very cool to work properly. Incandecent bulbs don't use heat sinks because they need to heat up to thousands of degrees just to get a small fraction of the photons they emit into the visible range. Now which do you think is wasting more energy?

There is no way to pack an efficient transformer into such a small space.

I doubt that any CFL or LED on the market is using a plain 60Hz transformer. They're using switching power supplies, which can be very efficient. That's becuase they crank the frequency up to a range where a small transformer *is* efficient.

Houses need wired seperately with a lower voltage appropriate for powering LED lights.

You'd still need a switching power supply to match the low voltage to the exact needs and wiring pattern of the particular LEDs. That's why most every PC have a separate power supply on the motherboard just inches away from the main power supply to convert 5VDC to whatever the processor needs.

Not to mention the power loss of low-voltage wires. If you put 100W of LED lights (about 6 bulbs) in a room at the end of a 50-foot run at 5V, you'd be pulling 20 amps. If you used 14AWG wire, at 0.25 ohms for the 100 foot round trip, you'd have a 5V voltage drop just from the resistance of the wire. You would also be violating code, which would require you to install a dedicated 12AWG circuit just to power 100W. That's obviously completely unworkable.

In summary, all of your uninformed "gut feel" opinions on these technical issues are unsurprisingly wrong.

It says it's parabolic right in the summary.

TFA shows a parabolic dish made of smaller mirrors. Those mirrors may look flat, but there's no way that they get "2000X" solar concentration unless each individual mirror is also precisely curved.

The whole setup looks far more expensive than conventional solar panels of the same area, or even a larger set of solar collectors capable of gathering the same amount of energy.

Actually, as soon as the garbage men show up, it's the governemnt's trash. I don't see why they shouldn't be free to do whatever they want with their property.

If it's the government's trash, why are they threatening ME with a fine if THEIR trash has too much food waste in it?

Because you have an agreement with the government that they will take possession of some types of your undesirable property in exchange for fixed fee. Part of the agreement is that different types of undesirable materials have to be segregated in order to reduce overall costs, direct and external. You did not properly segregate the materials as specified under the agreement, and therefore pay a specified surcharge. Presumably, this surcharge helps the government offset the cost of having to build a new landfill earlier because the current one is filled up with your otherwise compostable food waste.

Nobody is holding a gun to your head and forcing you to segreagate your waste according to the government's specifications. You're always free to load your garbage in your car, find a privately run landfill who will accept it as-is, and bring it there.
