When was slashdot not for the lulz? Nerdbait + random quirky interest stories was always the formula. The quirky story selection left with CmdrTaco (heard the tragic news on the radio this morning, sad for one so young and gifted).

Comment A life without steak ? (Score 3, Informative) 189

Look you can be vegan or whatever if you want, but I think I'll take the risk and eat my juicy barbecued steak. As for the methane : it contribute only roughly 25% of the warming that CO2 does. The reason are simple : the half life of methane in the atmosphere is short and the quantity of methane are 1/200 of those of CO2. And then enteric fermentation is barely above 16% of total methane emission (all farm animals counted, not only cows). Coal mining , oil drilling and treatment is above that , about 19%. Then there are other sources, rice cultivation (12%), waste treatment and landfill (12%), burning of biomass (9%) look up wiki if you wish for more details and more importantly : the sources of citations. Sure we should keep in check, as long as we don't concentrate on "cow" and follow other venue , like reducing coal and oil CO2/Methane emissions.

US Air Force Wants To Plasma Bomb The Sky To Improve Radio Communication ( 159

An anonymous reader quotes a report from New Scientist: [The U.S. Air Force has plans to improve radio communication over long distances by detonating plasma bombs in the upper atmosphere using a fleet of micro satellites. It's not the first time we've tried to improve radio communication by tinkering with the ionosphere. HAARP, the High Frequency Active Auroral Research Program in Alaska, stimulates the ionosphere with radiation from ground-based antennas to produce radio-reflecting plasma.] Now the USAF wants to do this more efficiently, with tiny satellites -- such as CubeSats -- carrying large volumes of ionized gas directly into the ionosphere. As well as increasing the range of radio signals, the USAF says it wants to smooth out the effects of solar winds, which can knock out GPS, and also investigate the possibility of blocking communication from enemy satellites. [There are at least two major challenges. One is building a plasma generator small enough to fit on a CubeSat -- roughly 10 centimeters cubed. Then there's the problem of controlling exactly how the plasma will disperse once it is released. The USAF has awarded three contracts to teams who are sketching out ways to tackle the approach. The best proposal will be selected for a second phase in which plasma generators will be tested in vacuum chambers and exploratory space flights.]

Comment Re:Driving yes, but charging? (Score 1) 990

Errr. No.

It's 90% of the total vehicle days they included in the study (cars only - they did not mention freight?). And there is no information about the 10% that is not covered is distributed. So there is no information on whether:

* 10% of people could not use EVs.
* 100% of people could not use EVs 10% of the time.
* Somewhere inbetween.

So you are just speculating, yet you are trying to state it as fact. Do you have more information than what was available in the abstract or are you just projected your beliefs onto the story?

You do have a right to stop someone from saying things that a reasonable person would perceive as threatening.

And there's very little that someone hundreds of miles away from you can say over the internet that a reasonable person would perceive as threatening.

Someone in the same room with me, or standing in front of my house, saying "I'm going to punch you in the face for what you said!" is a true threat, the person has the imminent means and opportunity to carry it out. Someone in a different city tweeting "@tom_swiss I'm going to punch you in the face for what you said!" is not a threat. Their arms just aren't that long.

Can somebody tell me why motivation makes a difference?

Because intent matters.

Intent is a very different thing than motive. Motive, in your example is the reason why the first guy planned his murder: for gain, for the lulz, ethnic or religious or political hatred, whatever. The act is still one of deliberate intent, regardless of motive. Your second guy had no intent to kill.

Motive may matter when we turn to the question of how to rehabilitate a criminal. But it can play no rightful role in defining a crime.
