    I have the HP Color LaserJet Pro M255dw I love it. I got it new last year. Sure its been complaining about low toner for 90% of that time but it still prints and they look great. I don’t have hp software installed, I have the wifi turned off and just use the ethernet hookup. airprint from my phone works great also. Its never once refused to print because one of the toner colors are empty. Sure it complains but it still prints. I can’t say the same for any inkjet I have ever owned.

    Never buy consumer grade printers. If the ink is more expensive than the printer you are going to get hosed in the long run.

    I had a brother laser before but it pulled so much current at warm up that it caused a brown out that tripped all the ups’s in the house.

  • Any time you need different behavior between static type checking and runtime.

    in 3.10 I’m using it to work around issue with NamedTuple generics. typing_extensions.NamedTuple allows Generics at runtime but typing.NamedTuple doesn’t. But the type checker we are using doesn’t support typing_extensions.NamedTuple like it does for the typing version so we lie at type checking time to get the typing to make sense but have different runtime type because otherwise its a TypeError




  • Yeah zero downtime. You ship out the new features but gate them using some system you can control. When all the new features are shipped you turn up the new features until it gets to 100%. This lets you observe the real world behavior of the new features if they don’t cache well or cause 500s or what have you you can turn it off without having to ship new code.

    Also if you keep all these feature flags, if you have a situation where you have capacity problems you can turn down features for the survival of the service as a whole.
