This is exactly what we do where I work. We send them a small problem that any competent person can solve in 15-30 mins in Python/Java/C++. It is amazing what an effective filter this is and submitted results range from fully test

Well I am not sure about Facebook but a relevant comparison might be the British newspaper the News of the World[1]. It held an (assumed) unassailable position as one of the oldest and most widely read English language newspapers. It was sh

You are only looking at the economics of accidents which are very rare. Economics also exerts a powerful influence on operations and with modern airliners with supercritical wing sections they can really only achieve optimum efficiency for

Since few accidents happen in the cruise the more useful measure is fatal accidents/1m departures rather than hours or miles. In 2013 it was 0.16/1m departures for jet airliners[1]. If you took two flights a day it would be, on av

I think that it is merely a consequence of when you have a small number of people that get a huge benefit which is paid by the rest of society contributing just a little each. It is greatly in the interest of the smaller group to continue t

I think Paul MacCready really solved a different problem. Earlier man powered aircraft (SUMPAC, Toucan, Puffin etc.) had been based on glider (sailplane) technology that emphasised the highest possible lift/drag ratio achieved by large

Cython is a code generation tool so it is often much harder to understand what the (intermediate) code is doing in more complex cases. This is especially true with numpy specific Cython code. And with Cython your debug story is more problem

I used to be a glider pilot (and an instructor). A disadvantage of a yolk is that when you are flying one handed and apply g (or encounter turbulence) the g forces on your arm induce roll inputs, a stick reduces that. As most powered aircra

I think what the author meant was that the elapsed time to sort: t = k * O(f(n)). So given two algorithms that have the same O(f(n)) then the smaller the k, the faster the sort.

OP here. You are right that C++ is moving away from the preprocessor (personally I can't wait for modules to save me from #include hell). CPIP was not intended to advocate advancements in the preprocessor but merely to make preprocessi

I doubt it. Jinja2 is a templating language for generating web pages. CPIP is a means of understanding what the C/C++ preprocessor is up to. These are unrelated.
