(*) Keep in mind that I'm critiquing the course, and not Professor Koller.

Are you sure? Why not? Presenting anything by reading the slides is terrible. People read faster than they speak, so while the presenter drones on, the audience has already read the slide and is just awkwardly sitting there waiting for the presenter to shut up and get on with it.

People have muddied the water about what terrorism actually is.

Terrorism is not simply doing something scary. Terrorism is causing harm, often grievous harm, to people in order to make them do something. NOT just to scare them.

Varies by company and time. I've had Radio Shack refuse to sell me stuff without a phone number. That was probably in the 90s. Lately, Sears has been getting aggressive about it. I got lectured with some crap about Sears becoming a "member oriented" company by some college educated sales guy who couldn't get a real job, when I politely declined to give them my phone number.

Good for you, Sears. Keep the merch. I'll buy it from someone else.

Ever check your bag as you walk out to make sure you have all your goods?

Yes, I check MY bag. I check MY wallet to make sure I put my credit card back. I don't go rummage through the store's storeroom to make sure my stuff isn't there.

It's implied when you walk into a store that they have the right to protect their stuff (security cameras or whatever else)

No, you think it's implied. I don't, and I never steal and hate being treated like I might have. It's also not their stuff once I've purchased it, and I don't like being asked to prove that my stuff is really mine.

That usually works painlessly not, but back in Ye Olde Daye I had Radio Shack refuse to sell me things (batteries, of course) because I wouldn't give them a phone number. As you might expect, that led to a good many years where I couldn't think of a good reason to enter their stores.

Funny coincidence, them going bankrupt and all.

We have a thing called the Supreme Court which decides such things. They did make such a decision, and it is not "Any law which does so is automatically void."

We have pictures of 5000m wide lava tubes on the moon? Link, please? I never heard of that. Pretty cool if it's true.

You have it exactly backwards. We don't know that they're there at all. All the study claims is that it's possible for them to exist because gravity alone wouldn't collapse them. GP is right, there are other things that might collapse them. You're also sort of right. IF they exist after all this time, it's pretty darn certain they're structurally sound.

Do they exist, though? We don't know.

Foolish, IMO. My ex has a friend who was about to cross the street, made eye contact with an older gentleman who motioned to her that it was ok to cross, then promptly hit her when she tried. Turns out he never saw her and the gesture she thought was telling her it was ok to cross had nothing to do with her at all.

IF self-driving cars work as planned, they'll always notice you. They'll never (ok, nearly never, aka less than a comparable human driver) hit you. If they aren't provably better than human drivers, they shouldn't be allowed on the roads, and I daresay in this litigious society, never would be.

Anti: blah, blah, blah, self-driving cars will never be good enough, they're unsafe, they don't think!!!!!1111 Panic!!!1111
Pro: Yes, they're wonderful and never distracted and will be better than puppies and rainbows!!!!!11111

It's really simple. People who want it to work are trying to make it work. If you antis are right, they won't be good enough and they'll never be much more than a curiosity. If you pros are right, they'll be provably better and the anti argument will be simply refuted by saying "Look at the data."

Really? It needs an iPhone?! That's comical. I don't want an iWatch (or whatever they call it) because I already have an iPhone and it's in my hands often enough that I don't need to strap a small one around my wrist. I don't even like the iPhone much anymore. It was outstanding when it was the new kid on the block, but now there are others just like it (and in some ways better) and iPhones have developed their own stupid, annoying problems, just like every other piece of technology.

I'm expecting a flop, too. Don't need, don't want, won't buy.

The turbocharger doesn't extract energy and turn it into shaft power. The turbocharger uses energy in the exhaust to spin a compressor (aka turbocharger) which shoves more air into the engine, which lets you burn more gasoline. That's where the power comes from.

Try it. I have. Yes, there's thinking. You have a toolbox of techniques, and so does your opponent. During the fight, you're testing what in your toolbox works against them, and learning what they have that works against you, then you're trying to compensate. You're trying to deceive, making your opponent try to defend the wrong shot so the one you actually throw hits them.

Yeah. There's thinking. It's not exactly chess, but it's far from two guys just punching each other.

I trained in boxing for a year and a half. I've been a runner for 20+. The cardio output required in boxing is significantly higher than running. That's where the "healthy" bit comes in. If you've never tried it, you have absolutely no idea what incredibly good shape you have to be in to compete.

Yes, I grant that getting punched in the head hard is not good, but other spotrs have their risks as well. I used to rock climb a lot. The risk profile there is that you're pretty likely to never get injured, but if you do, there's a decent chance it's going to be really bad.

Everything has risks. I'm against decrying one activity because YOU don't like it's risk profile. If you don't find it acceptable, don't do it. I loved rock climbing tremendously, and I'd have hated for someone to take it away from me because they thought it too risky. Certainly, I talked to enough people who felt it was too risky. I'm not going to take boxing or MMA from those who find it an acceptable risk, and neither should you. We should, however, be up front with people about the risks and let them make an informed choice.

No, I don't.

Then again, dropping my kid off at school this morning I saw one parent almost crash into another at 5mph because they weren't paying attention. It's not like I feel safe now.
