What sensors does the Model S have? I'm surprised that Tesla sold a car with enough sensors for semi-autonomous operation without the actual software until now. For those with more knowledge about cars, how does the sensor array in the

Serious question: In what ways is CS theory high-impact? I'm particularly interested in any arguments that complexity theory is high-impact (beyond the very useful insight that there are some problems for which no polynomial time algor

Middle distance runner here, disagree with most of this. I agree that there's not much point for a beginner runner to worry too much about form. However, simply running a lot does not give most people efficient form (it does prevent th

I agree that it's hard to find low-level work with equivalent pay to web development/frontend/etc. I think this is a reason that the "learn to code" movement focuses on Javascript and Python rather than C. From my l

I hugely agree with this. I first learned Java in a year long high school class. As soon as the class was over, I knew I liked programming and wanted to become a better programmer, but I also had the feeling that there had to be something l

I think the author's argument can be split into two generalizations: (1) people who know C are better programmers (2) people who learn Python first never learn C I think (1) is generally true. I would be interested to hear someone expl

I'm not very experienced in representing money in computer programs, but I thought the best practice was to store all values as integers (using either cents or smaller as your unit). Any reason you chose to use doubles instead of integ

nVidia's PTX is the most similar thing I can think of (and I know nVidia's GPGPU products pretty well right now). PTX is an ISA for a virtual machine, which makes it similar to HSAIL. PTX doesn't come with a memory model spec

Forget non-free CUDA runtime, there are larger problems with the CUDA toolchain with respect to free software. The actual instructions executed by Nvidia's chips are pretty much undocumented. Nvidia provides great documentation for PTX

Single precision is about 2.5x faster than double precision on current GPUs (for matrix multiplication, which is compute dominated). It really depends on the application, but in my experience more often than not the only reason you are usin

Julia has very little (more or less zero) symbolic manipulation library work right now. If I were to write a Wolfram Alpha alternative in Julia right now, I'd do all of the symbolic manipulation using PyCall and sympy.
