Install NoScript and enable scripts globally in its options. I do this and it's like it's not even there, but once in a while when I'm on a shady website, it'll pop up and say that it blocked a suspected malicious script or XSS attack. Better than nothing.

I got my Arduino Uno a few weeks ago and have had a similarly positive experience. You do need additional components to if you want it to do anything cool (LEDs, sensors for sound/light/movement, motors, buttons, etc. Think input/output.) You could get an "Arduino Uno starter kit" that includes everything you need to start having fun, but it's probably cheaper to buy the components down at RadioShack or your local electronics store.

Benoit Mandelbrot practically invented a new field of mathematics that we now use for everything from measuring the size of forests to identifying cancer in its early stages. He was the best of mathematicians.

Eight months ago he gave a ted talk describing his work. If you want to explore fractals for yourself, I recommend GNU XaoS for all platforms.

Has she played Minecraft yet? Not only does it not tell you how to play (or what the goal is), but you can't tell someone how to play it.

Every weekday at exactly 11:00 AM, the UPS truck drives past my house. Whenever I purchase goods online, the UPS truck drops it off at 11:00 AM. What's the carbon footprint of my order? I would have to guess virtually zero.

Exactly.

I once asked a young child who was smart in math what 4÷3 was. When he gave the answer 1.333, I said I would check it on my calculator. I punched 4/3 into my TI-89, hit =, and got 4/3 as an answer. The boy said that's not the answer and was confused that the calculator would say that. I argued that 4/3 did indeed equal 4/3, so it's a perfectly fine answer.

A calculator usually gives you an answer with a denominator of 1. For example, say a car is traveling 40 meters per 5 seconds. Enter 40/5 in a calculator, in it will tell you that it's traveling 8 meters per 1 second. It could have told you that it's traveling 80 meters per 10 seconds, and that answer would have been just as correct.

Knowing the calculator's logic is useful, because you can now enter "5 seconds / 40 meters" to know that the car is takes 0.125 seconds per 1 meter.

Actually, 75,000% of the original cost would be a 74,900% markup.

Python has a human-centric method of working with floating-point numbers: the Decimal class.

This is a perfect example of the Dunning–Kruger effect: People tend to overestimate their own level of skill and fail to recognize genuine skill in others.

"The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt." — Bertrand Russell

If I write a document in Microsoft Word, does Microsoft own my paper? If I use Photoshop, does Adobe own my image? If I Auto-Tune my song, does Antares own it?

I thought there was a law that prevented the makers of the tool from grabbing the rights to its user's creations.

Being in or on the water in a thunder storm increases your chance of being injured or killed by lightning. When it strikes water, the current spreads out in all directions and dissipates within about 20 feet. And as the highest object on the water, you increase your risk. 13 percent of all lightning fatalities nationwide involve boats and water.

Still, the chance of injury or death is tiny. So why do people take all these precautions? The answer lies in just who these people are. If someone does get injured by lightning while swimming and the people who own or protect the beach or pool hadn't taken any precautions, they could be sued. So these people aren't taking precautions for your safety, they're taking precautions for their own good.

For example, I wrote a free Gimp script for web design that helps create (what I call) a website window. I doubt it has an official name.

I would use these terms for those who create a website:
Front-End Web Developer (HTML/JavaScript)
Back-End Web Developer (server-side scripts)
Web Designer (graphics)
