Comment Re:Guarantees (Score 1) 260

Where I work, a year of advanced education is treated as a year of experience. You can pay enormous sums of money to go to school, or you can keep working and make money to achieve the same end result. It really doesn't give you any incentive to get an advanced degree.

If you want to move into management, you really need an MBA, not an MS or PhD. However, many technology companies don't acknowledge the fact that scientists and engineers with MBA's command a much higher pay scale. There is a big demand in the financial industry for people with those skills. (i.e. Knight Capital Group, etc.)

The real advantage to an advanced degree is the thesis. If you write an excellent thesis that gets people's attention, through a combination of hard work and luck (i.e. researching an emerging technology), you can land an interesting job. It has happened to some coworkers of mine. However, you can publish great work, while getting paid, if you have the right job. My advice is to find a new job that is pushing the limits of current technology and get published. That will open some doors.

Comment Re:But how smart? (Score 2) 465

Google deliberately avoids the more challenging situations, and a LOT of those miles are highway

I work in the auto industry and have seen miles used as a metric in a number of tests. The problem with using miles as a measurement in an automotive test is that highway miles are inherently different than city miles. A manager always says, "this vehicle needs to last X miles. Get the verification data as quickly as possible." The product validation team immediately goes out and puts X highway miles on the vehicle because highway miles are the quickest way to rack up miles.

Later on in those programs, we usually find some issues when the product operates in a city or low speed environment. I've been pushing for vehicle hours as a replacement every chance I get, but people don't listen...

Comment Digital World (Score 1) 1086

In a digital world, classical calculus isn't used very often. To be honest, I forgot most of it. The big thing you should know how to do is integrate. Instead of an integral, you will typically use a Riemann sum in programming. However, Riemann sums are taught in most calculus classes, and you should be aware of how it works in comparison to an integral.

I'm not a software engineer, but I do a lot of programming for data analysis purposes. Yes, I think you should take calculus. Not because you will use it directly, but because of the more abstract concepts you will learn while taking the class.

Comment Re:MATLAB (Score 4, Informative) 477

Python + Numpy + Scipy + matplotlib tends to do the job the same, if not better, all whilst being easier to write and debug.

Sorry, but MATLAB is the industry standard. As big of a pain as it is, we have a huge repository of functions already written in it. There's just too much momentum to change. Believe me, I tried!

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.
