  • I was in a situation similar to this one in real life: having to adjust the salt level in a pool.

    In metric:

    The pool is 8*4 m long and 2m deep on average, the current salt level is 2g/l and the salt comes in 20kg bags.

    How many bags of salts do I need to pour in the pool to adjust the salt level to at least 3g/l ?

    Answer:

    ! The pool contains 8m4m2m= 64m³ or 64000l of water, I need an extra 1g/l of salt per litres so 64000l*1g/l = 64000g or 64 kg. So with 4 bags I’ll have enough salt.

    In imperial:

    The pool is 20*10ft long and 5ft deep on average, the current salt level is 2000ppm and the salt comes in 40lbs bags.

    How many bags of salts do I need to pour in the pool to adjust the salt level to at least 3000ppm?

    Answer:

    ! I’m just gonna drive to the store with my truck to pick up 2 bags at the time and see if it’s enough, no way I’m doing the calculation.










  • I think tailscale would fit your use case perfectly.

    You can install tailscale on your computer and your NAS. This way, there is a tunnel between your computer and your NAS. In practice you will have a separate IP address for your NAS that you can use from your computer.

    It also means that you will have secure access to your NAS from wherever in the world as long as you have internet access.

    Then, Mullvad and tailscale are integrated together. It means that from tailscale you get the Mullvad add-on that allows you to use Mullvad as exit-point. Meaning that all your traffic that is not in your tailscale network will go through Mullvad (so in your case everything except your NAS)

    It’s been two years that I am using that and it’s working great for me.
