I tried for a day to get Linux installed on my Mac. I thought Boot Camp would be perfect; it repartitioned the drive nicely, but I couldn't get Linux to load. I couldn't delete the Windows partition, couldn't remake it as a Linux partition. Eventually gave up. Is there a way to do this?

You can finally print mirrors with this, apparently. Quite cool

Thank you. I just couldn't understand it; although clearly the clues were there and you interpreted them correctly.

So the UV light goes through the bottom window, through the oxygen-rich zone that will not polymerize. When the light gets through that zone, it polymerizes the resin. The polymerized resin must block the light from going deeper into the liquid resin.

If you have a thick part, though, I wonder if this could work? New unpolymerized resin would have to flow into the gap between the hardened part and the window, and this 'dead zone' is only microns thick. Now, I do believe that most 3D printed parts aren't solid blocks; but this could be a limitation.

Still, looks quite cool. I am sure that I'm not alone wanting to build stuff with it!

The area of the earth is 4,000^2xpi square miles, so even with 4,000 satellites there is one for every 12,000 square miles. OK, perhaps the very high latitudes don't need to be covered, and you can get that down to 10,000 square miles. For the United States, the average population density means that on average, you'd have 500,000 people covered by one satellite. Europe, Japan, China, Indonesia, and many other countries or regions have significantly higher population density. For cities, this is just a non-starter.

Now, Musk is not a stupid guy, but I just can't see how this works.

If you read further, they talk about restrictions on mothers eating while lactating as well.

My mom ate a lot of peanuts when I was a few months old, and I almost died of peanut allergy. I question this result.

55 years later, I'm still deathly allergic to them. It does add some adventure to life.

Yes on the light-based-communication, but no on the use of frequency-shifting polymers...that's new.

It's not particularly uncommon for an article about a scientific breakthrough to be almost satirically misleading.

If this really works, for instance, it could be a revolution in television design; far better than the quantum dot technology that people are adapting now. But, if the article was about TVs then it the responses would all go in a million directions (comparisons to plasma, talking about energy star ratings, whatever).

Back in the 50's, it was pretty common for scientists doing nuclear weapons research to talk about things that would happen in stars of unconventional configurations; when they were really broadcasting to the USSR that the US scientists had solved problems with hydrogen bombs that put them far ahead.

Go to a friends house and turn on their flat-panel TV. 99% of the time, it will have frame-rate interpolation turned on; which basically means that any content they see on that TV will be at 60 or 120 Hz. Even movies shot at 24.

More and more often as I do presentations to executives, they don't understand why my TVs look so "juddery" compared to what they expect -- it's because at home they're watching everything at 120Hz.

So no -- most people are happy with high frame rate most of the time, and that percentage is getting larger quickly. I am a big 24fps fan, but I believe the days are numbered.

No, we are not doing things that are artificial at all -- we are making things that could be far more real.

The Dolby Vision TVs will have reasonable controls to set brightness and contrast, but one of the selling points to the studios is that we will strive to maintain the artistic intent of the original. The blacks will be black, the whites will be white, and there will be an unprecedented (but realistic) amount of contrast.

It turns out that in high dynamic range content creation, the most important thing is not that the picture be brighter overall; but that there is an increased range between midtones and highlights. In current production, skin tones are set to about half the maximum brightness in the scene. This means that the brightest things in the image (say, a glint off of a chrome bumper) can only be twice that bright; where in real life it's more that 100 times that bright. So, leaving the midtones about where they are, and giving brighter highlights makes the image look better in a way that you have to see to understand. Or, you can just look out the window.

As the article states, two of the most important changes in this standard are high dynamic range (HDR) and wider color gamut (Rec. 2020) images. I have been working on this with Dolby Laboratories for the last few years, and whenever we bring in movie directors, cinematographers, colorists, or studio executives to see our ridiculously HDR wide-color-gamut display, their jaws hit the floor. The ability to reproduce the dynamic range and color gamut of real life is breathtaking. One of the studio executives, when asked if she could see the difference said "Do I look like a potted palm?"

You will see the difference, and you'll be able to see it from across the room. HDR and wide color gamut combined with UHD resolution is a revolution.

I know this sounds like a sales pitch (ok, it is!) but I've been working in the film business for 30 years before I started working on this; I know what creatives want, and this is it. I spent that time working on CG visual effects, and I think that HDR will have a comparable impact on filmmaking that VFX did.

The Dolby Cinema theaters opening in the next few months will have similar extreme dynamic range and wide color gamut. They look astonishingly better as well.

Wait and see. It's coming, and it's not far away.

That is the point, of course. We're going to see more dramatic climate changes in the future, probably, and we'll be able to go back and point to these votes. Politicians can deny a lot of things, but the votes are on the record forever.
