> But in any case, a missed opportunity for vectorisation is just that: a missed opportunity. It is not abstraction overhead. Does the same code implemented in C manage to vectorize? If so isn't that an actual "cost" in co

How much did making the video cost? When I first saw it I thought that commercial itself must've cost around the ballpark of the amount you were trying to raise (30k) and can't possibly be worth it. But turns out it was a brillian

How much does immutability/persistence cost in terms of performance and memory? Are there benchmarks against std::vector? E.g, are we talking about 10x or 100x slow down?

I thought the going rate for researchers is supposed to be pretty high. For example for self driving cars it's supposedly 10mil a head: http://www.recode.net/2016/9/17/12943214/sebastian-thrun-sel...

I wonder if this "hack" can be automated completely. Input a bikini pic and output a fake nude with some magical content aware fill that can stitch boobs on. It should be good enough to fool the loaner but leave you with a clothed

Standard path as of maybe half a decade ago was to do a masters or phd in financial engineering (sometimes alternatively named computational finance). I personally believe it's hard to self-study since there's many graduate-level

Because it doesn't matter with modern day CPUs with typical file sizes and typing speeds. Worst case scenario for a plain array is if you insert to the front of the array where it has to shift everything down one. But even if the file

What should I google to find out more on this topic? Why do they need double precision if they aren't doing computation? Is it actually visible to the human eye?

I wonder if facebook and google could've built a better model. Prediction based on polling doesn't seem as reliable compared to what people post to their newsfeed or search for.

Where does the selection pressure come from though? I have enough faith in our race that even if we have someone who is genetically less fit for mars we won't just let him die before he reaches a reproductive age. So will it be by thei

There are a lot of very cool math properties hidden in each of these examples so I want to start a discussion on modeling some of them: For the "memory" example, each particle is moving Uniform(-k, k) at each timestep (where k is

I am not sure if your original solution will actually work. For example an attacker can just spoof enough accounts to sample from your distribution to figure out the true center. Imagine spoofing a grid of users with let's say K fake a

Not in the robotics sense where you map out a hallway of a building or something. But it does map facial landmarks very well (and I suppose that will also give you localization relative to the face).

Google internal libraries and infrastructure are very good and way better than most "off the shelf" libraries. Any rank and file engineer can and do contribute to them. In that case I don't see why they should lower their bar
