> The crew of a 99.9% lightspeed ship doesn’t experience time dilation until they return home.

That's not true. They see the universe around them moving much faster.

Time dilation has nothing to do with "returning home".

But from our perspective, the outside observers, why do black holes gain mass? It would take an infinite amount of time from our perspective for any mass to even touch the event horizon.

Your numbers are outdated. Thin film = 23%, multi-junction are 46%.

"Standard PV" is probably what's available in bulk and cheap, is around 22-25%.

That's the thing that never made sense to me about the black holes. The closer you are to the event horizon, the faster the time passes for the universe around you. So reaching the event horizon should take infinite amount of the "outside time", so right before you reach the horizon, you should see the whole future of the universe, including its end, if there's any.

So how do black holes gain any mass then?

I feel like they will get sued for that extremely quickly, considering their dominating position (Chrome) and being in the ad-serving business at the same time.

Why would any reasonable company decide to warn people of red light cameras? People who go through red lights are freaking dangerous.

Blockchain. Namecoin, in particular.

It's still extremely useful, even with those false positive rates. You will scare a few people, but they will just retest and maybe will improve their lifestyle.

Maybe even more, if they invested ALL the dollars into bitcoin since their inception. That would be smart of them in hindsight. If that's the case, they could be sitting on $5B+ worth of BTC (or maybe a basket of cryptocurrencies).

Just start an ICO, there are not that many medical ones. You already have all the right buzz words to raise a few billion ;)

I looked at the i7/16GB/512GB/UHD version, it's over $2K.

Why not get a Surface Book instead for $1600?

There's a huge difference between what evolved organisms can adapt to, and the conditions necessary to start life.

Look, humans already adapted to being in space for prolonged periods of time. We adapted to every climate. But drop a naked human in a random spot on our planet, and he will die with high degree of probability. And that's after billions of years of evolution.

It's not the noise that prevents us from seeing distant planets, but the diffraction limits.

But what a joke. Compare:

That's a good thing. Low-end GPUs suck anyway, but add so much weight and power consumption.

So is this a good PRNG?

But corporation collections as paperclip maximizers is a bad analogy. Corporations generally produce something large numbers of people want (be it solar panels or cars in his example), whereas a paperclip maximizer AI produces paperclips that only it wants, destroying everything in its path.

It works in commercial cameras like Hasselblad H4D-200MS.

Being a programmer, but not an engineer, I always wanted to try to create a camera with the ability to micro-shift the sensor in both directions, increasing the resolution. If you shift 3 times by 1/3 of the pixel on each axis, you can theoretically 9X the resolution (well, megapixels). Of course, it won't work for dynamic scenes, but could be quite useful for industrial scanning or looking for house insulation problems.

That's what I don't get.

Which websites are radically slower on iphone 6+ compared to 7+?

And the camera - what use case are you talking about? Taking family photos to post on Facebook? If so, how is that "hugely important"? Taking professional photos?

I understand it's "fast", but what do you use that speed for to justify spending so much more money? I understand if you're so wealthy, you're willing to pay $800 more to open Facebook a second faster than me, but I don't get why an average person would do something like that.

An $800 graphics card has an immediate use case: high FPS for games at high resolutions and high settings. Which is very important in competitive gaming, for instance.

I don't see such a use case for a $1000 smartphone. What important task does it solve that a $300-400 phone doesn't? A slightly better camera, slightly smoother scrolling, slightly faster web page rendering. None of that impresses me in the slightest, these improvements are marginal.

If I want a low-light camera, I will buy a DSLR/mirrorless, and no smartphone comes even close to something like Sony A7s (~$1100 used). I used to do commercial portrait photography, so I know.

I also dislike the fake background blur / bokeh trend. I understand why the companies are doing it, but it's insanely hard to implement it right, and no phone has achieved it. Every time there's hair involved, they all fail.

Which websites are you talking about? I'm yet to encounter any important ones that are really slow.

What do people buy $1000 smartphones for? For gaming I can get a pretty good gaming PC for that amount, or Xbox One X with a VR headset.

I've never seen anybody do anything really cool with their phone - everyone browses the internet, checks the email, does chats/videochats, maps, take photos, and some silly mobile gaming. I do that all on my sub $200 phone.

I'm somewhat sure we will turn trans-human in the next 50 years, and then all bets are off. There may not be humans, not because we die off, but because we turn ourselves into something better, totally different.

1000 years is a long long time to make any predictions. Predicting 10 years into the future is hard enough.
