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 20k shipped? Doubt that. (Score 1) 67

There is a lot of dissatisfaction from many people over on the Oculus forums due to lack of information and shipping delays. Many who ordered within the first 48 hours after orders opened on March 19th have not received units or even an update other than "we're working real hard to ship orders as quickly as possible".

Based on comments from the forums, information given about how many were sold how quickly and feedback from the oculus forums, about the only way they could claim that 20k were shipped is if they were shipped from the manufacturer to the distribution centers, not the customers.

Oculus has had my money from March 20th and I'm yet to receive any kind of shipping confirmation. They did not sell 20k in the first 24 hours.

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.

I foresee the time when we dump Industrial Education and start providing kids all the education they can handle at any age and quit trying to pigeon hole them into "age" segregated classes, and start putting them into online sessions with educational peers

That's interesting, but I don't see what you rant has to do with school districts providing laptops. If the incumbents keep promoting programs like OLPC through the schools, then I can assure you that the world will actually be moving away from your vision of reformed education.

And at $200 ea. Chromebooks offer even the lowest income people a chance to own technology that can help bridge the education gap. $200 buys one, maybe two textbooks these days, something school districts have to do every year or two. Are they as capable as a Laptop? Probably not, but they are usable for 85% of what kids need in school.

Wow, I am amazed at how many people seem to lack basic reading comprehension. I explicitly had said, "I would be in favor of a program that provides these devices to low income families." I am in favor of equal access for all and huge believer in the benefits of technology. Putting a laptop into the hands of every child at school will not give them those benefits.

To be honest, I don't know whether or not to feel sorry for your kids, or you. Here we live in an age where the world is at your fingertips and you spouting off like it is a pure scam. Kind of hypocritical of you being on /. (using a computer and all) don't you think?

Your pity is adorable, and quite ignorant. I own the following devices that are available to my family of 6: Three laptops (two mac & one windows), one mac desktop, four tablets (two ipads and two kindles) and two Linux servers. My kids have every benefit, and I would advocate for that same access for all. But seeing as you have little desire to read and understand the people you argue with, it's understandable how you could hold all sorts of irrational emotions.

There is nothing that providing a laptop per child affords that can't be accomplished through classroom media presentation devices (computer & projector) and a good school computer lab.

Homework. Many poorer kids do not have a computer at home, and a smartphone is terrible for writing papers and research. The laptop/tablet is also locked down so distractions are kept to a minimum.

These devices will only be a distraction and huge expense for families and schools as millions of them are broken every year.

Hyperbole. Citation needed. Yesterday's article about iPads in Coachella said district-wide there were less than 10 lost or stolen. How does that scale up to millions?

I'm replying to comments now, and it's amazing how person after person has responded with, "but what about the poor kids?!?!" Apparently everybody has terrible reading comprehension, for I said, "I would be in favor of a program that provides these devices to low income families."

I read the iPad story on Slashdot. That is an amazing story, and it made headlines because it's [going to be] an outlier. Have you ever purchased a new piece of equipment? You baby that thing at first, then as the familiarity grows, your defenses drop and you end up making mistakes. As devices in school becomes more standard, this problem will only grow.
