    I honestly don’t know how tall I am. I know I’m taller than last time I was seriously measured, but I don’t know by how much and I don’t care. But everyone shrinks during the day anyway. Measuring height to precise centimeters has just a little more sense than weighing someone with precision of ⅒ of kilogram. I have basically no chance but to estimate and possibly round.



  • There are colour scales that combine colours and intensities consistently, so that if you discard (or can’t percieve) colour information, you still get a nice black to white scale. For a moment, I though the map used cviridis scale, which has this property and is designed to look as similar as possible to people with various variants of colour blindness. But then I realised that the scale used here has the brightest point in the middle, not on one side.







  • I relatively often meet 4 of these:

    • no speed limit (use the normal limit for this type of road)

    • car tires may defy laws of nature (slippery road, usually followed by a sign saying it applies during rain)

    • speed camera ahead

    • no water polluting goods (not very common, but occasionally comes up. There is also no dangerous materials with an orange trapezoid instead of an ellipse)

    I also saw don’t drive off the pier (around ferries), watch for skiers (in the mountains with cross-country skiing routes), and warning about planes, although in different design (around airports).

    That didn’t sound right, my experience that depending on luck and season, somewhere between 50 and 90 % of big mushrooms I come across in a forest are poisonous or at least disgusting. I admit it’s a very wild estimate and I’m very far from knowing all the mushroom I come across, but still, that seems like a big contradiction. So I followed your link to the primary article.

    I suspected that they might only count potentially lethal mushrooms, but no, it indeed seems they count even those that only make you nauseous. The problem is in the other number. The 100 000 means all funghi, it includes for example all yeasts. Most funghi don’t create mushrooms that anyone would consider picking. So the ratio you calculated below is WAY off.

    I would also like to note that the number 100 seems to come from a very simple PubMed search. Basically, if nobody wrote a paper about someone being sick after eating a mushroom, they wouldn’t find it. I don’t think that would mean that many foraged mushrooms would be missed, but it is a limitation worth knowing about.



  • Not so much Amanita phalloides as Amanita pantherina, that one looks much more similar. But I agree, if you know what you’re doing and don’t pick mushrooms with which you don’t have experience with and aren’t sure about, you’re good.

    I used to pick up even Amanita rubescens, an acual (although edible and tasty) Amanita, so even more similar to poisonous ones. But I didn’t have an opportunity for quite a few years and now I wouldn’t dare, until I got an opportunity to verify with someone experienced and trustworthy.




  • Also, how is the direction assigned? Especially for streets that are not straight? For example taking a beginning and end and measuring their angle wouldn’t be very representative. And how does it work with long and short streets? Are longer more heavily represented, or do they count the same? I’d like it if it took a tangent to the street every 100 m or so, but somehow I doubt that’s what they did.
