Comment Re:Doesn't distilled water taste horrible though? (Score 3, Interesting) 167

Pure water does taste a little off, which is why bottled water companies add minerals to their product.

If this is a big concern for athletes or anyone else using this system, they could easily transport a very small amount of mineral mix to dissolve in the water to fix the problem.

Personally, I'd be shocked if this was the biggest problem. Athletes require far more fluids than this will be able to provide. I don't see this being practical.

Of course we all use available code. I would be very disappointed if my colleagues were all writing their own sorting functions when that problem has already been solved a million times.

But that's not what school is about. You need to go through the process of understanding how these algos came to be understood--not so that you can re-implement them in your job--but so that you can do two things:
1. Know which algos will work when you do have a real world problem to solve
2. Use the same process that helped you solve for a known algo when the time comes to solve for an unknown one

Please, use available libraries and stack overflow on the job. But let's not pretend that we're trying to accomplish the same things on the job and in the classroom.

1. Quantum fluctuations are not nothing, but I guess we have to sell headlines here
2. Inflation Theory seems faster than "exponential" expansion. We're talking about a theory that went from the size of a singularity to something bigger than the visible universe in 10^-32 seconds. Exponential is quite pedestrian compared to what is theorized.

That said I typically stand back aghast at today’s Republican conservatives – I may be wrong, but in general they seem mean and – yes I’ll say it – bigoted. Of course that could just be Dunning-Kruger blinding me to the brilliance of the current Republican vision.

I agree with you, but I also think the following is true too: :%s/Republican\|conservative/\={'Republican':'Democrat','conservative':'liberal'}[submatch(0)]/g;

Comment How Would Hawking Radiation Dissolve a Black Hole? (Score 2) 66

In all my years of reading and thinking about black holes, one question I've got about HR his how it would actually end up causing the decay of a black hole. From what I understand, HR is the spontaneous creation of matter and anti-matter in space that would normally annihilate itself (allowed by QM theory)--the key difference is that this event can happen at the edge of the event horizon. With some positive probability, the anti-matter will be created within the event horizon radius, but the matter will remain outside and escape. When you look at the whole system then, the anti-matter will annihilate matter within the black hole (causing it to "dissolve") and the matter will remain outside the clutches of the black hole.

I'm sure I'm describing it very simplistically, but I believe my question after that should work for all systems that are analogous:

How is the HR process not symmetric? Whatever would cause the dissolution of the black hole--how would the same process happening in reverse (matter falling into the black hole and anti-matter escaping) not cause equilibrium to be maintained?

Comment Re:Not this again. (Score 1) 637

I would disagree that C isn't good enough, but I do agree that at least a semester of asm would be helpful.

Watch out for mips though--that's what they used at my uni, and while it taught the principles that are found in all architectures, I found it discouraging that our only interaction wound up being through a vm. There was an excellent electrical and computer engineering class that used x86 assembly, and that's the one I'd recommend any CS student take (assuming your school offers something like that).

Finally, I think there is a skill for "memory management" that must be learned in Java (not letting the garbage collector ruin your day), but I'm not sure it's something you can learn through class when you're happy enough to get the proper incantations of javac and java right.

I'm curious what the interview questions were, if you wouldn't mind sharing.

I interviewed with ms back when I was in college (in the early 2000s) and remember my questions along with those of my classmates. They seemed challenging at the time but now seem trivial based on the real world experience I've gained.

Do you have some examples you'd be interested in sharing?

Comment Re:One more reason to not watch NFL (Score 2) 107

They will get used a lot. I worked on the sidelines of the Bears one season and was amazed that they could only look at still photos (though if you flip through them, it practically looks like video).

This is a very natural progression to the game, and something that should have been done long ago. The whole MS/Surface/blah stuff is obviously marketing added on (why not if the nfl can make a buck or get a discount on the devices?). But I guarantee you that players will be glued to these things. Getting real-time film feedback is going to be huge, no matter who provides the technology.

Comment Re:What do I think? (Score 1) 225

Thank you for offering a very sensible reply. I agree that the right implementation would make a difference, and I suppose part of my being upset is not trusting our school district to do it right--they certainly have not offered any indication that they will do anything novel with these laptops. They just came in to a little extra money and it's burning a hole in their pocket.

I hope they offset the cost by putting open source textbooks on them, but I'm skeptical. School districts (including mine) seem to be happy to hop into bed with lobby interests (teacher unions, publishers) and someone the kids always come last. I hope they offer programming instruction, but I'm skeptical. I still think you can offer outstanding programming courses with a good school computer lab, but honestly, our kids are going to get neither through the schools. But I find joy in supplementing at home and have already worked with my oldest to learn some logic through Scratch.

Interactive/multimedia education is largely overrated from what I've seen. Personal, relational and interactional pedagogy seems to be the most effective, but laptops will drive education further from that. The temptation will be to build curriculum that turn the classroom teacher into little more than a babysitter.
