    Not too bad but the "rednecks" depiction reeks of class contempt.

    It would not even get close to a finding any kind of optima, but you could.

    I'm wouldn't be so sure about that:

    Here we demonstrate they can: we evolve the weights of a DNN with a simple, gradient-free, population-based genetic algorithm (GA) and it performs well on hard deep RL problems, including Atari and humanoid locomotion. The Deep GA successfully evolves networks with over four million free parameters, the largest neural networks ever evolved with a traditional evolutionary algorithm.

    And some of the more advanced evolution strategies algorithm are really good and are well understood (iirc CMA-ES has a proof of global convergence for example).

    I've been using the Victorinox for like 5 years and it still cuts very well. I love the handling too, definitively made cooking more enjoyable.

    It's not really about zombies, it's more about the interaction with the other humans. It's definitely a landmark in adventure games. It is gory at times though.

    Kinda, although the left version basically means democracy (in a more direct sense that is most representative governments). This issue is very pressing in some country like Switzerland where direct democracy is under pressure from the EU. The left doesn't have a very good story or vision on sovereignty, while the far right has a much easier job with their nationalism.

    In Europe sovereignty is something that the right portrays to promote, while some part of the left has abandoned or forgot the concept (popular sovereignty is a left-wing concept historically). The right however will often use "national sovereignty" instead of "popular sovereignty".

    I watched Leave No Trace from Debra Granik (that also did Winter's Bone), it's about a broken veteran that try to live out of society with his daughter. It's based on a book and some reals stories. It's in the social realism vein, trying to depict these type of people accurately, while still being aesthetically pleasant and avoiding pathos. The actors are really good (the young kiwi girl playing the daughter is amazing for her first movie), the pace is slow, the story subdued, but I wasn't bored.

    I'm quite desperate with US movies (too many super heroes & bad SF) but that's a movie that gave me back a bit of hope.

    I use it for scientific computing mostly, biology, statistics, machine learning, etc.

    I think it's better than R for statistics, for example if you want to compute the density of a Poisson distribution at the value x you do:

    pdf(Poisson(5), x)
    

    At value 0 to 100:

    pdf.(Poisson(5), 0:100)
    

    If you want to take the quantile your do:

    quantile(Poisson(5), q)
    

    If you want to fit it to data you do:

    fit(Poisson, data)
    

    Integrate it between 0 and 100:

    sum(pdf(Poisson(5),k) for k in 1:100)
    

    You can probably guess how you draw random numbers from a Normal. In R you have your dpois (or ppois, I never remember which is which), qpois methods and a plethora of function with random names that don't compose into anything,

    Scipy is nicer than R (being object oriented), but it's also pretty slow, so doing your own sampling, optimization or integration can be a pain.

    What's great with Julia is the you are not forced to vectorize your code for performance, so when it makes sense or you feel like it you can just write for loops. You can also use a more functional style without penalties, so it's quite freeing.

    I love the broadcast syntax too:

    julia> (x->x^2).(1:8)
    8-element Array{Int64,1}:
      1

    Julia, for multiple dispatch, performance and generally elegant design. It just feels more fun to code with it. If only they could magically fix the loading/compilation times.
