Comment Re:Jeremy Clarkson (Score 1) 639

Whoa! The summary says the person in question posted:

'You let your dad down i hope you know that.'

Which isn't nice, but by no means a threat.

My fault for not RTFA, but making a threat is a criminal offense in any country, including the United States.

Once again, another poorly written, and inflammatory summary.

Comment Re:Just a higher tech version of what cops already (Score 1) 180

Ok, so first, if the crime doesn't happen, how do you know you prevented it? Maybe it just didn't happen.

The simplest answer is a Double Blind Study

I use a similar modeling technique to tune engines. Their model must have police presence as one of its input factors, since it's the only factor the police can control directly. Before they implement this system, they should perform a "sweep" of this input to establish a correlation.(i.e. vary the amount of police presence) Once the model is created, an optimization algorithm can be used to determine the most effective use of police resources. (i.e. maximize arrests per officer)

A nice advantage of a system like this is the model can be continually updated. The more data you have, the better the model can become. If the criminals start using some sort of anti-prediction method, I would expect the police would see a drastic drop in their coefficient of determination, and the model would be useless. However, I don't think most criminals are that smart. I think most criminal activity is rooted in some basic sociological rules, too ingrained to be easily changed.

I don't see this method helping an individual cop on the street. They would do their job as usual. What will change is at police HQ in large cities. It will help them determine boundaries of precincts, staffing, and patrol routes.

Comment Engine Size (Score 1) 543

The way I figure it, sizing of the engine will be the trickiest part. Here's what I would do:

1. Figure out how much power you need to get the vehicle to go down the highway at a typical highway speed. I'm thinking 80mph is a good number, you don't want to go too low. A coast down test is the simplest way, but a rolling road wind tunnel would be the best if you can afford it. Remember to have ballast in the vehicle to simulate a fully loaded vehicle.

2. Factor in losses from your transmission type, including generator and electric motors. Plus remember to include power for air conditioning, an alternator and other power accessories you may have.

3. Select an engine. Unless you are having an engine custom made, it's not going to have the exact requirements you need. To save money, you will have to make some sacrifices. Don't forget to factor in what we engineers call "packaging". You will be installing a lot of hardware on to this vehicle and the shape of each component will become critical to ensure it all fits.

Also, it's popular to separate an engine bay into two separate sections if possible. The "hot side" is where the exhaust is. Anything that will be hot enough to fry electronics, or ignite fuel should be located on this side of the engine. The "cold side" is where your air intake is located and any sensitive electronic controllers.

I'm thinking the engine you select should have a maximum power output that is equal to the power required to drive the vehicle at 80mph (see step 1) plus any accessories. Any accelerations, or hills climbing should be performed by relying on your batteries for reserve power. Regenerative braking can be used to make up this power, as well as running the engine at maximum load while the required load to drive the vehicle is low. (i.e. the Volt's mountain mode)

Beware, diesel engines that are approved for gensets must meet different EPA requirements than those in on-road vehicles. While a genset engine is fine for your one-off vehicle, it will not be allowed in a production vehicle.

Comment Re:Not the best possible home (Score 1) 63

One thing I remember about the Intrepid was the fighter jets on the flight deck with shattered cockpits. Unfortunately, it's not been possible to date to keep vandals off of the ship. So, keep watching how they take care of the Shuttle. If there are problems, we really should start lobbying for a different home.

Although I agree it's necessary to keep the shuttle in good condition, I cringe at the thought of a "pavilion" on the deck of that historic old ship. The museum needs to decide whether the Intrepid or Enterprise is the main attraction, and get rid of the one that isn't. Enterprise was never intended to be housed on an aircraft carrier, and the Intrepid was never indented to house a shuttle. Modifying or neglecting either goes against a museum's purpose of preserving objects from the past so they may be enjoyed by others in the future.

The very definition of being an asshole is acting in a manner that the most people would find offensive, or most people would determine to be against established rules of society.

My point is, the men that assaulted Steve Mann feel he, according to your definition, is an asshole.

Disclaimer: I personally have a different definition of asshole and do not think Steve Mann is one.

A more accurate statement would be a substantial portion of people are wary of significant novelty . But that wouldn't fit your pop-psychology agenda, would it?

I think people fear those that reject their societal norms is a better way to phrase that. I also argue that this applies to everyone on some level.The only reason you haven't noticed it is because everyone around you conforms to your concept of normal. However, if someone started walking around a public place in the nude, you would call the cops. (That's not normal!)

I propose that the individuals in this story emotionally responded to this man wearing his special glasses in the same way you and I might react to some streaker. However, they didn't call the cops. They didn't avoid eye contact, or stare at him, as I imagine most people do. They instead assaulted him (which is outside of our societal norms, hence this article.)

Pushing in front of a queue does indeed violate social norms, but it's not "being unique", it's being an asshole

Why is it "being an asshole" as you put it? It sounds perfectly reasonable to me. I'm not familiar with this "queue" technique you are talking about. My culture uses a different method. *devil's advocate*

Waiting in line is entirely a custom created by our civilized society. Any parent of a preschooler will tell you that waiting in line has to be taught and doesn't come naturally. However, it is ingrained into our social norms at such an early age, that we refuse to accept anything else.

Refusing to wait in line is only "being an asshole" because you were taught that way when you were very young. Perhaps the individuals in TFA were taught wearing fancy electronic eyewear was "being an asshole".

Everyone fears what is different from themselves, or what they have accepted as a social norm. It's an evolutionary trait that allows humans to live and work in groups, and allows primitive tribes to keep sick individuals from infecting the rest of the tribe.

Eventually most of us learn to ignore this trait as our higher thinking can do a better job of perceiving what is a threat and what is not. Apparently these individuals perceived this man's uniqueness as a threat on some level, so they attacked him. It doesn't excuse this behavior, but that's what happened.

There was a very good episode of the TV show Head Games about this topic. They had some actors do things that go against our social norms, like refusing to stand in line. Those actors were nearly physically assaulted.

all I really feel the need for is some more RAM

I upgraded the RAM years ago. I've found that RAM is really cheap shortly after a computer comes out. If you wait too long though, it becomes extremely expensive as the market dries up for the old stuff.

Heck, I've got a 6 year old Core2 and I don't see a reason to upgrade. I'm not a heavy gamer, so I don't require a fast machine, and everything seems to be running fine.

PC speed improvements just aren't that noticeable these days. They are also much more reliable than they were 15-20 years ago.
