  • A stretch goal might be 24/7 running a pi zero or openwrt router next to it so you can turn the machine on remotely.

    The benefit of doing your work or learning on that machine, even if your laptop is faster, is that you can offload heavy or long running things and save your laptop battery when mobile. Want to compile something? Run some local llm job? Build a new docker image? Start it, close your laptop and go about your day. Open it later to see the thing is done and your laptop still has 99% battery. (This will require, at minimum, learning about SSH, tmux, networking, wake on lan, and probably VPNs like wireguard or tailscale, or maybe dynamic DNS - lots of fun).

    You do need something running all the time to do remote WOL because those packets don’t work over the Internet, but there are lots of Linux computers that use less electricity than your typical bedside alarm clock. Even an old phone might work.







  • A paper notebook is basically the same fundamental as a password manager but with a different tradeoff. You trade cryptographic security for a reliance on physical security. Its probably a great option for a lot of older people who only log into things from home. But its just a password manager. An analogue one.

    Flashcards are dumb for this. If you are going to write it down, just secure it. Don’t have them out all the time to try to memorise it. Jese. The worst of both.



  • Plenty of research on the topic. Humans cannot remember a unique, high bit random password for each service. Using your brain means one of the following. Low bit passwords that can be cracked, memorable passwords that can be guessed via social engineering, and/or password reuse where one breached service breaches many accounts.

    The only known solutions are all based on some sort of actually random generation of passwords, combined with storage of some sort for all but a very small number of extremely important examples (typically just your password manager vaults password). I actually think a paper notebook and dice or card system is an under appreciated option for a lot of people, which falls under the above.

    There is one weird alternative, and that is deterministically generated high bit passwords (via a cryptographic hash function). Unfortunately it doesn’t work well with stupid snowflake sites that have their own “good password” rules, and falls completely flat when you have to change passwords for just a single or few sites for whatever reason.
