I would be extra careful about the "billions" of social fraud in France.
Wikipedia make a difference between the shortfall due to unpaid contribution (undeclared work for example) and the loss due to benefit fraud.
Different figures are given but it looks that most those "billions" are in fact shortfall and not benefit fraud.
That was a bit expected, and the reason given by Nature are not the whole story.
Some of the same authors also claimed to have found metallic hydrogen [0], which is also highly controversial since the proof hold mainly on pictures taken using a Iphone camera.
It is a very active domain, with lots and lots of techniques to do some clever approximations.
Brute forcing is not feasible, even for the simplest systems.
That is essentially the idea of Random Structure Searching [0], but the precision of quantum simulation (better known as ab initio) for solids is not perfect and very time consuming.
Same as you, but I took 90% on the time only on the last line, the first three are solved use basic swipe of two squares, as in a beginner cube method.
I understand that employers' choices are not really yours.
But why did you choose to use Sublime Text for developing and vim for the command line ?
I don't know very much of vim but I think it is very extensible and can be used as a complete IDE for most of languages. Wouldn't it be more convenient to always use vim over switching between vim and Sublime ?
