  • 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.



  • Ah, that’s good then.

    In Australia you really only need a name and date of birth and ID such as a passport or driving license number of the owner. No physical or even photographic proof. Some phone companies send the original sim a notification before moving it, but no response is required and moving the number often only takes 10~30mins.

    Banks in Australia commonly use sms codes as 2fa.

    A large percentage (20~30%?) of adult Australians have had their ID details leaked in recent years because there are no adequately enforced security requirements or data-retention limits. One of the largest breaches was the second largest mobile phone provider…
