Six Electric Cars Can Power an Office Building

hrimhari Easy... (296 comments)

Next up: Why not just do this using batteries--never mind the cars?

Because they were bound to be plugged in to recharge anyway. That way they're doubling as batteries for the building.

Electric Vehicles Might Not Benefit the Environment After All

hrimhari Re:Depends on the energy source duh! (775 comments)

An electrical heater is not a system, it's just part of one. The system itself would at least involve the energy source and the transporting medium, where the losses continue to hold true the fact that there's no 100% efficiency in any system. If there were, Entropy would have no meaning.

If you take the isolated case of the heater as being 100% efficient because in itself it's able to convert 100% of its input energy into wanted heat (which itself is discutable, since there may still be losses through electro-magnetic emissions, vibrations, etc. that would not be captured by the room and transformed into heat, even though all that would be as negligible as contesting gravity acceleration as not being 9.8m/s^2 in most cases), you'd just as well pick a heat pump which, with the same amount of input energy, "produces" 3 times more heat.

Electric Vehicles Might Not Benefit the Environment After All

hrimhari Re:Depends on the energy source duh! (775 comments)

Heat pumps are 300% efficient. Maybe we should use heat pumps instead of electric cars.

Electric Vehicles Might Not Benefit the Environment After All

hrimhari Re:Depends on the energy source duh! (775 comments)

What I meant is that the fact seems to be "electricity is way more efficient than combustion" rather than "electricity is 100% efficient. Gas is not".

As far as my ignorance in the laws of Physics goes, it's simply impossible to have any system running at 100% efficiency because it automatically implies zero loss of energy.

Electric systems lose energy everywhere: conduction materials have impedance, motors have friction *and* generate inductive impedance, photons are created...

Man Of Steel Leaps Over Record With $125.1 Million To Mixed Reviews

hrimhari Re:I hated it (364 comments)

Superman is an alien, brought to Earth on a spaceship, and has super powers. WHAT DID YOU EXPECT?

How about playing the evil guy to unite the Earth governments under a single goal and thus avoid the general destruction of humanity? Hmm, that sounds familiar.

Ok, I got it! Fight AGAINST the destruction of OTHER impressive things like the Great Wall of China, the Everest, Iguassu Falls and such, instead of DESTRUCTING a Manhattan-like city while fighting the enemy.

Man Of Steel Leaps Over Record With $125.1 Million To Mixed Reviews

hrimhari Re:I hated it (364 comments)

Thank you for putting into words what I have been feeling since I watched it.

What I kept from the film was interminable mass-destruction scenes with little care to a believable script. A waste of good character canon. I can't imagine why any significant number of (new) fans would look for any other merchandising or media after that.

Volvo's Electric Roads Concept Points To Battery-Free EV Future

hrimhari Sounds expensive (216 comments)

Road maintenance is already a problem on many a government's budget. I have the impression that adding a complex system of energy delivery which includes encryption and selective power-up seems too complex.

Thousands of Whistle Blowers Vulnerable After Anonymous Hacks SAPS

hrimhari Re:Out of character... (132 comments)

I can understand why a group interested in justice and equality would expose the sensitive details of people in the databases.

I understand that as meaning "this group doesn't know how to pick their targets".

And it's not like there's not already a whole lot of danger and unfairness in South Africa -- the "net condition" will not really change.

So let's put people trying to make things better at risk?

(...)Pubic awareness and especially global public awareness will have been raised

The awareness I get from this is that hackers can give a huge blow against whistle blowers with no real "net gain" to any cause.

Physicist Proposes New Way To Think About Intelligence

hrimhari Re:when I want to maximize entropy ... (233 comments)

No, because it puts an end to "long term". To maximize entropy over time, one needs to keep as many options open as possible, so that one pushes the "end" to as far as possible.

Isn't it interesting, though, that if the Universe really follows this principle, that such a system would evolve into finite lives?

For Jane's, Gustav Weißkopf's 1901 Liftoff Displaces Wright Bros.

hrimhari Re:What? (267 comments)

he took the design of the wright flyer and bolted wheels onto the bottom of it

The only thing the two designs have in common is that they both have wings. This is the model that Santos Dumont successfully presented in 1906. And this is the model that the Wright Brothers used to be the first to fly an airplane.

Note that Santos Dumont's model takes off on its own and lands, while the Wrights' model is launched by an external device and cannot land without crashing (since it doesn't have wheels).

hrimhari Re:Gutenberg wasn't first either (267 comments)

By the time the Great War had started, European aviation was greatly ahead of the USA's efforts.

Thanks to a Santos Dumont's invention, the Demoiselle (Google translation), which was released to the public domain by the author.

Highway To Sell: AC/DC iTunes Snub Finally Over

US Puts Tariff On Chinese Solar Panels

hrimhari Sorry article, but the summary is discouraging. (311 comments)

I refuse to read an article where the summary leads me to believe that the writer doesn't understand what subsides and import taxes are for, which is, to promote local development in detriment to imports.

RIM Trying To Woo Customers With Porn, Gambling Apps?

hrimhari Re:I dunno, are they? (157 comments)

Funny that you would think every town works exactly like Minneapolis and that people having different experiences must be liars.

In Montréal, Québec, the monthly transit pass costs $ 75.50. When there's a snow storm, some buses simply disappear. It's not what I'd call a pleasant return home to wait 1h+ under -20oC for a bus that won't come. And there's no service status information for buses. When I depended on that service, I decided to walk 40 min to get to the subway instead of waiting.

On the other hand, it could have taken 40m (1h if we want to be really pessimistic) to drive back home on the same weather conditions instead of 20min under normal conditions.

Heartland Institute Threatens To Sue Anyone Who Comments On Leaked Documents

Murdoch says Amazon e-book prices kill paper books

hrimhari hrimhari writes  |  more than 4 years ago

hrimhari (1241292) writes "The settlement between Amazon and Macmillian got the attention of a known dinossaur. Consistent to his views, Mr. Murdoch wants to defend his book editors by killing the cheaper solution.

"We don't like the Amazon model of selling everything at $9.99," Murdoch said. "They pay us the wholesale price of $14 or whatever we charge," he said. "But I think it really devalues books, and it hurts all the retailers of the hardcover books."

Global Warming good to economy. So was slavery.

hrimhari hrimhari writes  |  more than 6 years ago

hrimhari (1241292) writes "Finally someone took the time to assemble parallels between the 'Global Warming, so what' trend and previous rhetorics. Marc D. Davidson of University of Amsterdam does just that using the pro-slave arguments[PDF, 205k] from the past."

Millionaires ask Congress to raise their taxes

hrimhari hrimhari writes  |  more than 3 years ago

Warren Buffet is leading the way to show Congress how to solve the budget puzzle. He published his net income and how much tax he paid, questioning why people who make money from money are taxed way less than people who make money out of real work.

The utterly trollish comment here. I guess that every commenter has a day of involuntary trolling? Maybe /. should come up with a -1 Disagree, or a moderator moderation :)

In my experience, Pair programmers are more than twice as productive as a single developer when you factor in all the errors and bugs prevented by having two sets of eyes on the same problem.

In my experience, unicorns are 2.7 times better than mermaids at debugging.
