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.

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.

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 that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.

I appreciate it if my grammar or style is corrected (in any of the languages I use here).

@fafo What's the deal with the delay(?)? Is the location unchanged?

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

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

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'll get a Gaussian random variable, with -- expectedly -- mean of x*y, but somewhat surprisingly with variance x.

It's somewhat nice (and surprising for me) that the variance is independent of the Bernoulli distribution skew.

The implementation of USB-PD (fast charging) has solved the issue of differing rail power standards across Europe.

At the cost of allowing only one train per catenary segment. :)

@phos@not.an.evilcyberhacker.net If it's in a different location for this night, it's a significant piece of evidence: it's carried by someone who spent each of these nights in a different place, which is atypical. Similarly, it would be interesting to note that it's moving at night: this means it's with someone (or something) that travels at night, which is also atypical. Did you explicitly ask that driver about potential shift changes at HBF? (I would not assume that drivers and conductors have same shifts.)

@phos@not.an.evilcyberhacker.net Where is it at night? If it doesn't ping at night, is the area where it's in the evening somewhat consistent? Whom do you mean by the driver? Driver of the train you lost it on, or a driver of one of the trains it was on? I see that others already mentioned the possibility of it being the same train, but serving different services. How do you know what service it was on board of? (I don't know how often trains that pass through a station but don't have a stop there actually stop for a short while somewhere nearby anyway, or drive through very slowly in Austria.)

@gabrielesvelto Tangentially: I would really appreciate it if Firefox didn't look at how low the _system_ is on memory, but (on OSes where this is a thing) look at the cgroup/other resource allocation process group it's in. (e.g. I run Firefox in a cgroup with a memory limit, so that I can leave some memory aside for everything else in a guaranteed fashion.)

@gabrielesvelto How does this relate to unload-tabs-on-memory-pressure mechanism? (I would naively expect that to always run out of unloadable tabs first; is that the case?)
