http://www.realtransit.org/nec7.php has some interesting charts and analysis of the speed limits on the various segments of the Northeast Corridor. Note that the values shown are not necessarily what it achieves in practice, but there's seemingly potential to address that via operational changes and small, targeted capital spending.

Not a book, but https://hackattic.com/ is in this vein. It's not the standard coding challenge website it may seem to be, instead a collection of small projects representative of the core ideas underlying "real world" systems. It provides just enough scaffolding and direction to get one started down the path of autodidactic exploration; satisfying and enlightening without being frustrating.

Summit and Sierra are two planned DOE machines with hardware developed in collaboration with IBM and Nvidia. They're slated to feature Volta GPU, a generation past P100's Pascal.

To corroborate its seriousness, I actually had a ticket issued to BER in 2012 that was changed to TXL about a month before the flight.

As far as JavaScript performance goes, they seem on par according to their own benchmarks at http://arewefastyet.com/.

Another worthwhile list to look at is the Green500 [1], which ranks machines based on MFLOPS/Watt. With the exception of a few GPU and Xeon Phi heavy machines at the top, the high end is dominated by IBM's Blue Gene machines.
