Re:TGV unveils high-speed trains of the future on Thursday September 15, 2022 @05:10PM (#32858502)
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.
Re:Pascal GPUs on All Fronts Push Nvidia to New Highs on Monday November 14, 2016 @03:41AM (#12948384)
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.

Re:Is the Berlin Airport ready yet? on Thursday June 04, 2015 @11:22AM (#9659887)
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.

Menkes van den Briel did some work on airplane boarding. He has really nice explanations and videos here: http://leeds-faculty.colorado.edu/vandenbr/projects/boarding...
Re:Learn C The Hard Way on Saturday July 02, 2011 @10:53PM (#2722932)
The arrow operator and identifiers with leading underscores seem to be glossed over or skipped fairly often in education. It's intimidating to look at code that uses them if you don't know what they are.

I bet there's a market in the opposite, too.

Re:Ask HN: What kind of personal financial investment do you do? on Wednesday February 09, 2011 @12:48PM (#2198417)
CDARS is a simplified way to do that with CDs, essentially distributing amounts past the FDIC limits into different banks behind the scenes, so that you only have to deal with one account, but get insurance on the entire amount.

Twinings Earl Grey and San Pellegrino do it for me.
Re:Ask HN: Learning advanced math on Sunday October 03, 2010 @01:38PM (#1753138)
Michaek Spivak's "Calculus" is pretty great for learning real analysis. The other canonical text is "Principles of Mathematical Analysis" by Walter Rudin, which I've never used, but is purported to be of the same quality.
Re:LaTeX CV Template on Tuesday September 21, 2010 @08:03PM (#1714615)
I used this template when I redid my résumé a few months back. I like how it does away with those extraneous bullets and lines found on many résumés; it is uncluttered, elegant, and very readable.
