An excellent discrete maths textbook for those missing the inclusion of the subject in the course: Discrete Mathematics - An Open Introduction, 3rd edition by Oscar Levin

Yeah nah, that’s not the way. Sure people can get away with it, but it’s really not eliminating the hazards.

There’s a bunch of non-obvious hazards which exist around cutting into containers which have held fuels, including but not limited to:

• An empty propane container could have an gas+air mixture inside it in proportions which could explode.
• Any liquid residue in an empty fuel container can be vapourised by the heat of the cutting, creating a fuel+air mix which can spontaneously explode from the pressure and heat, even without sparks (think: diesel engine principle but instead of a 0.25L cylinder it’s a 200L cylinder).
• An empty gas canister can be contaminated with heavier oils/waxes that could build up over the years of refilling cycles, creating the same hazard as noted for empty liquid fuel containers.

Methods to reduce the hazard include:

• Thoroughly washing the inside of the container before cutting (access can be difficult though).
• Filling with water and cutting while full of water. (Container musn’t be sealed, and the cutting method must be safe to use in a wet environment, and further hazards such as introducing oxygen into the container need to be considered).

Handy to have an offline translation dictionary. I’ve used QuickDic for languages I know how to type, but I notice there are a bunch of more specialised Japanese dictionary apps in F-Droid that can search by radical or OCR if you don’t type or understand the characters.

double-check for security vulnerabilities

triple-check is better.

Part of me thinks you’re being unreasonable, because that question did receive decent responses (1 CLI + GUI suggestion, 1 GUI suggestion, and 2 beginning to try troubleshoot the drive access problem).

But I suspect it’s just a dissonance in perspectives, maybe due to your Linux distro causing a bunch of stupid issues, which haven’t been properly noticed by anyone yet.

It’s a shame that some distros like Ubuntu have enshittified so badly that they’ve become unsupportable. (Nothing seems to work rationally – the same reason I find it impossible to support users on Windows).

Advocates and potential/new users alike, need to consider specific distributions, not just “Linux”.

I’m partial to thumbkey. It even has a Lemmy community: !thumbkey@lemmy.ml
