<p>I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work on weird ML (we'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'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&#39;ll get a Gaussian random variable, with -- expectedly -- mean of x*y, but somewhat surprisingly with variance x. It&#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.
