<p>I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work on weird ML (we&#39;ll see how it goes), am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.</p><p>I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.</p><p>If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I&#39;m being inaccurate. I think

    If you perform the following procedure: 1. Draw A from Poisson with mean x. 2. Sum up A i.i.d. +1/-1 Bernoulli variables with mean y. You&amp;#39;ll get a Gaussian random variable, with -- expectedly -- mean of x*y, but somewhat surprisingly with variance x. It&amp;#39;s somewhat nice (and surprising for me) that the variance is independent of the Bernoulli distribution skew.

    I am going to CCC (#39c3). If everything works, I will be reachable by phone at 7275.

    An amusing way to explain that garbage input produces garbage output.
