Upon further reading, the setup is so sensitive that the thermal expansion of the pedestal the telescope was mounted to could interfere with the image quality.
It takes quite a while to collect enough light from 100s of light years away in order to create a usable image.
Don't forget, you not only need a long exposure time, but you also need to account for the earth's rotation. This guy must have some sort of servo setup to automatically track the stars in ultra fine increments.
As an engineer that works with heat engines. I don't see what is so difficult about making a small heat engine. However, if one were to make a heat engine seven orders of magnitude smaller, with the same efficiency of a full sized heat engine... THAT would be an accomplishment!
Unfortunately, both the article and the summary have left out that detail...
The classic problem with selling new cars is that the people who can afford to buy them don't care about efficiency.
You are assuming that people who are careful with their money will never find it reasonable to buy a new car. This is a wrong assumption. I just did the math a year ago when my wife needed a new car. Cars that are inexpensive to operate don't depreciate as rapidly as cars that are expensive to operate, and used cars are more expensive to finance.
When you factor in the difference in interest rates, it may only cost $1000 more for a new car versus one that is two years old. For only $1000 more, you could potentially drive that car for an additional two years.
The process of converting mechanical energy to electrical energy and back isn't 100% efficient.
Neither is a traditional transmission. Mechanical transmissions can lose up to 20 percent of the power put into them to heat. As long as the electrical efficiency is equal to or lesser than 20 percent (it likely is) it's a wash.
While searching for a job, I've discovered that many companies desire this "unrealistic optimism." A recruiter I was using sent me a list of questions the company was going to ask me, and "mistakenly" included the correct answers. Questions like, "How important is it for you to be the best?" have answers listed as, "Very important to be the best, not just 'do my best.'" Another question asks, "Are you a perfectionist?" and then lists, "must say yes," as the correct answer.
I think kids have such "unrealistic optimism" because it's desired in today's society. Unfortunately for me, I found college to be a very humbling experience, and I fear these kids will too.
I think you are being a bit harsh on Linkedin. Yeah, there is some spam. Spam is everywhere. However, in this economy, corporations are turning to LinkedIn as a recruiting tool.
When a company posts a position on Monster and Careerbuilder (I get spam from both by the way), they are flooded with resumes. The situation is so bad that their human resources departments don't have the resources to sort through them all. They therefore use LinkedIn as a search tool for candidates without opening themselves up to a deluge of resumes.
Yeah there is some spam on LinkedIn. There is spam on other sites as well, but it doesn't mean those sites are worthless.
To me, it's a little close to wearing a fast food uniform. It would bug me.
I only worked one summer in IT. During that summer we were required to wear a suit and tie all day. Let me tell you, it got expensive. Think about all of the crap that people have under their desks that you have to crawl through.
We ended up asking for uniforms because they were cheaper. If you get dirty at work, get the uniforms, and get the company to pay for them. If you never get dirty, don't get uniforms.
Same here. I've been using Chromium daily builds on my Ubuntu 8.04 machine for some time now. It runs quite well, Flash works, and it even has rudimentary support for adblock plus.
My only complaint is the regressions and bugs in some of the builds, none of whom have effected stability. However, bugs are to be expected in such a release.
I think the writer of this fine article is simply too picky, and using the wrong version of Chrome in the first place.
What happens when you click the Internet Explorer icon? Does it open Firefox? What happens when you click on the Windows Media Player Icon? Does it open VLC?
My parents have a basement watchdog. My major complaint is the amount of servicing the battery requires. You have to add the acid to the battery when you first buy it, and then add water too it every six months or so. There are a million warnings all over the thing about hydrogen fires and acid burns. It's really a pain in the butt, but better than a flooded basement.

A book called Socialnomics had some impressive marketing last summer. I wonder how it compares to the book above.

It took me a couple of minutes to realize the story was not about the Television Show.
I think you have watched one too many episodes of House.

Do you honestly think people are going to pay US$30-40k for a compact car that (feature-wise) compares to a US$16k Toyota Corolla?
They already pay $28k for a car that has the same features as a Toyota Corolla. It's called a Prius.

I really like the "Google is NSA" tag. I think it's my favorite conspiracy theory yet!
Well, a dollar is a dollar, a pound is a pound and a euro is a euro... until you start measuring one against the other.
Not true. A dollar 100 years ago does not equal a dollar today. The value of money changes over time. Especially when you compare it to the goods that can be bought with it.

Exactly!
Put a small heater in the traffic signal that turns on below 0C (32F).
Or better yet, wire the heater to one of these and have someone drive around and turn them on when it snows.
Either way, if the municipalities don't solve the problem, they will get sued. How much does that cost?

They're all maniacal engineers. *rimshot*
"mismanagement".
Why do you think they changed the department name from MIS to IT years ago?

I don't know... that one guy did create a people powered plane.

I'm confused...
Do these people even know what the word "maximum" means?
They're smart engineers.
