1. The "reverse-complement" problem here is simply about reading a file, reversing strings and mapping a small set of characters to another one and printing the result. This is rea…

This falls in the very specialized fields, but traders/brokers certainly need to be good at mental calculations.

If you want to read up more on this, look up third culture kids. The wikipedia page is a good start.

Not a single data point in this theory. The reason you sometimes wake up just before the alarm (at least I wake up before my alarm because I actually check the time) is because of …

It's a low pass filter. And I'm assuming the low-pass is used in the DAC to cut off high frequencies it cannot handle.

or just calculate the eigenvalues & eigenvectors of Q.

In this case, it makes no difference. The array is used instead of a struct to save a few lines of code and making the title of this post more impressive.

It's worth a lot. M&A or quarterly results can move stock prices quite significantly and knowing about those before they are public will allow you to bet against it on the market.

They do deprecate things, e.g. exception specification and the auto keywords was re-purposed.

copying the data was probably the bottleneck, not malloc.

Calculating greeks is not very difficult and bandwidth is going to be the bottleneck due to the high number of inputs necessary to calculate them. So no wonder that CPUs outperform…

Apple doesn't even tell you how much RAM their phone have. Or what the CPU/GPU frequencies are.
