Physics - awesome!
Chemistry - awesome
Biology - awesome
But I think he's wrong on some many issues. From the summary:
... he imagined laser-scanning every object in the Smithsonian for students to explore
...
Why? That's like looking at a single car from one country and claiming an "education". Think REALITY. The students could see HOW the objects were created. What tools were used. Who crafted the item. What the society was like that required it.
... and collaborating in shared virtual spaces rather than campuses.
They're called "chat rooms". Wanna "cyber"? Porn is NOT the same as education.
Looking at other students would be a distraction.
The next step past that is when you have shared space, and not only do you believe that this object is right there in front of me, but I look around and I see other people just like we see each other now, and I really, truly believe that youâ(TM)re right in front of me.
Why does it matter that you see avatars looking at the same point that you are looking at?
And he keeps going on about that. For him it is all about "seeing" other "people" (really just avatars) so it can be the same "experience" as real life.
That's stupid. They are not people. They are avatars. And knowing how people are, their avatars would be designed to be as distracting as possible.
Memory transistors are about a thousand times larger than CPU transistors. Do try to keep up.
There goes Apple, innovating, er, I mean copying Samsung again. Two or three years ago Samsung reportedly had run similar tests with sapphire screens and found large sapphire panels to be too brittle.
Incidentally, I purchased the iPhone 6 last year, when it was known as the Samsung Galaxy S4.
First, advertisers only pay if you click the on the ad.,/quote>
This is not true. Web advertising has three models, which are often used in combination:
1: Referral fee. When an ad leads to a sale, the ad hoster gets a cut.
2: Click-throughs. When an ad is clicked, the ad hoster gets a fee.
3: Impressions. When an ad is displayed, the ad hoster gets a smaller fee.
Paying for impressions is an important part of ad business - it's similar to billboard and magazine ads, in that the user don't click them, but hopefully remembers - if nothing else subconsciously, so the next time they're at the store they pick the goods with the logo and color combinations that's been impressed on them.
Actually they do and can but no one wants to listen. People just want a quick fix. It's called a well balanced diet and exercise.. Reply to This Parent Share
On the contrary, the fix is exercise and a well-balanced diet.
I've a very good idea that RAM prices are artificially inflated, that the fab plants are poorly managed, that the overheads are unnecessarily high because of laziness and the mentality in the regions producing RAM.
I'm absolutely certain that 15nm-scale RAM on sticks the same size as sticks used today would cost not one penny more but would have a capacity greater than I've outlined.
It could be done tomorrow. The tools all exist since the scale is already used. The silicon wafers are good enough, if they can manage chips 4x and 9x the size of a current memory chip with next to zero discards, then creating the far smaller dies (so you can discard more chips and still get the same absolute yield) is not an issue. It would reduce idle time for fabs, as fabs are currently run semi-idled to avoid the feast/famine cycle of prior years but 15nm would let them produce other chips in high demand, soaking up all the extra capacity.
What you end up with is less waste, therefore lower overheads, therefore higher profit. The chip companies like profit. They're not going to pass on discounts, you getting a thousand times the RAM for the same price is discount enough!
There are two ways to write error-free programs; only the third one works.
