The raw measurements API provides raw GNSS measurements so that somebody can implement their own position engine, and do things like RTK. The corrections mentioned in the blog post are calculated by the phone (in Google Play Services, using

Important caveat: Fourier series is a discrete sum over integer multiple of frequencies, while Fourier transform is a continuous integral over all frequencies. The former works for periodic functions, the latter for an arbitrary function. B

What I find fascinating about this equation is that is in the form of the diffusion (heat) equation. The fundamental solution to the diffusion equation is the Gaussian. So you can think of solving the equation as applying a Gaussian blur to

I just learned about this in the Mining Massive Datasets course at Stanford. The gist is that you can formulate the PageRank problem as a flow equation r = Mr, where r is a vector of PageRanks and M is a stochastic adjacency matrix, which c

Indeed. Improvements in efficiency often have the paradoxical effect of increasing resource utilization. This is known as Jevons Paradox [0], and it's been observed in many real world situations. [0] https://en.wikipedia.org

In a similar vein, I had good grades, but from a non-cs background (I studied engineering physics). A lot of recruiters were turned off immediately when they heard "physics" and not pure CS or ECE. Google was interested, though.
