  • Assuming you live in the United States, you need to be aware of the laws in the state you live in. Many states are one party consent when it comes to recording. Which means if you and I are having a conversation, you can record it without telling me. One party has consented.

    If on the other hand, you install a camera without your mom’s knowledge, then you are not one of the two parties. This “evidence” could be thrown out of court as it is “illegally aquired”.

    Not to say you shouldn’t do it. Protect your mom’s property. I would just suggest looking into the local laws about it. I am also not a lawyer so you should look into your local laws or consult a lawyer.



  • Depends on the kind of concentration. If I’m programming or doing some kind of math, I want fury. I’m reaching for Slayer or Megadeth or the Doom sound track. Nothing like Angel of Death to plow through something.

    If it’s more contemplative, power ballads. Something I can sing without focusing on it. I Want to Know What Love Is. Keeps pace, but it’s more emotional. Keeps me in that thoughtful place.

    Cooking, woodworking, cleaning. Something active but not on the whole fast. Heavy metal, southern rock, or blues. Kiss, CCR, Lynyrd Skynyrd, BB King. Something even tempo that can pick up and come back down. Freebird followed by Fortunate Son is a good example.




  • Unfortunately, sometimes (often) there is no man page for what you are looking for. So if you get a page not found, that’s usually the case. You can usually find associated pages all the way at the bottom. That helps when what you are looking for isn’t a command, but a reference. I don’t remember exactly where it is, but man pages are stored in a directory. Probably /etc or /usr. You can always dump that list into fzf or use grep to search to see if there is a page for what you are looking for. It’s not a perfect system by any means, but it’s a good one to have in your toolbelt.


  • I can appreciate that. Appologies if you know this already, but just don’t like them. Here are some tips.

    It helps a lot to get title/subtitle/flag highlighting. By default man pages are hard to use simply because of how dense they are. It’s much easier to skim when you can separate the parts you are looking for up front from the text.

    Don’t forget ‘/’, ‘n’, and ‘N’. First way to use man pages more effectively is to search them easily. And you can search via regex. Often I’m looking for more info on a particular flag. So I’ll press ‘/’ followed by ‘^ *-g’. For a g flag.

    Take notes on the side. It saves you time later. Your future self will thank you. And you learn a lot by skimming them.

    Man pages can be intimidating/confusing, but, imho, it’s worth training that skill. Even if you are slower up front, it’s totally worth it.
