> Do you have a clear concept of a viable solution?

Nuclear. Solar farms take 450 times more land than nuclear to produce the same amount of energy (source: https://www.forbes.com/sites/michaelshellenberger/2018/05/08...)


Sorry, but that's just a dumb comparison. For one, solar farms don't use land the same way nuclear power plants do, in terms of effects on the environment/ecosystem (you potentially can even do agriculture on the same land ...). Then, you can't install nuclear power plants on rooftops, but you can put solar panels there, thus using no land at all. And finally, you avoid a lot of losses and don't need as much distribution infrastructure when you have solar panels within the city where the energy is being used.

Also, I don't see how you could build sufficient nuclear capacity in time to sufficiently reduce carbon emissions without compromising safety (after all, nuclear energy is inherently extremely dangerous--the fact that we so far have been able to operate it very safely does not mean that that is an inherent property of the technology that we could maintain if we tried building hundreds of gigawatts in a decade). Nuclear (fission) energy might have been a sensible route in the past, but it doesn't seem so right now.


I think nuclear is the best current solution, but it is too late to build nuclear plant now because it requires 40 years to be cost effective. I hope that solar will become better than nuclear in less than 10 years.


Solar less space efficient even at maximum capacity.


This is hilarious, thanks for sharing. I used to work at companies like this, except they weren't worth billions of dollars.


Neither was twitter in 2008, it didn't reach $1b until the end of 2009


The story is most probably not true. Love the taco tunnel though :)

Edit: apparently the stories actually are true.


You still need to know a bit of assembly to take advantage of SIMD (even when using compiler intrinsics). See for instance https://github.com/lemire/simdjson


> you input N and it will produce the Nth prime

Look for Willans' formula (there's a nice explanation in the book "Hacker's Delight").


> If an entire Sci-fi continuity were limited to just Sol and Alpha Centauri, this by itself would constitute an inexhaustible number of potential settings.

"Saturn's Children" by Charles Stross is a good one (unfortunately he had to do away with humans to keep the space opera physically realistic).


Mostly humans with radiation repair nanomachines and shielding could do just fine, I think. (Saying more would spoil Saturn's Children.) Humans commanding autonomous drones should figure more into Sci-fi. "Away teams" of drones in real life space fleets should be more prominent. Instead of a transporter shifting bodies, we could have the shifting of points of view through VR teleoperation. (Which is really what a transporter was for in the original Star Trek series: Changing locations with minimal production expense.)


Yeah, and with OpenGL ES/OpenAL support it was pretty easy to port C++ games to the iPhone, with just a thin Obj-C wrapper.


As someone living in a third world country, I can't help chuckling every time I see people discussing "poverty in America".

Perl, 7s. Looks like I arrived at the same recurrence that madars used, but I swear I didn't look at his solution...

Memoize magically turns it from exponential to polynomial.
