  • I think his point is more that you might have multiple components that need database access in your app, so those component have a connection (or reuse a central access) and for simplicity reasons, you made 1 database for the whole app, rather than one per component. Once that happens there’s a new path that could be used to pass information between the components in a way that isn’t the function interface. Much like a global variable can be used that way. And there’s a risk you start to use the database like a global variable store.

    I don’t use databases much, so I don’t have a strong opinion, but it’s an interesting thought.









  • Remember, if you got fired, you might have fucked up or failed (might, still not guaranteed). If you got laid off, then your boss’ boss or C Suite fucked up. They made bad decisions and the business revenue didn’t show up as they predicted, and you’re just paying the price instead of them. So try not to sweat it, and recognize that unlike the 70s, a lot of companies now plan to grow aggressively and layoff at the first sign of danger.

    Hopefully you got a severance large enough to give you a bit of breathing room while you look for another job without too much stress








  • I do consider the master password to my password manager as my “thing I know”, and not the randomly generated passwords it stores. But you’re saying that have-vs-know is not really important in the security space, that was mostly just a handy shorthand?

    so are passkeys just a simplified workflow version of the complicated dance I have to do on windows to get git commits to push easily with the public key from putty-gen? But also the private key is sometimes locked to the device it was generated on? I guess I should read some actual technical docs on em.


  • I have a basic question, I learned that MFA should draw from multiples of “things you have” (totp) and “things you know” (passwords). There’s all this talk of passkeys replacing passwords, but aren’t passkeys in the “thing you have” category, not the “thing you know” category? My worry is that an unlocked computer or unlocked phone will let someone access ALL of a person’s accounts because now they have the thing and don’t need you at all. Putting access to my entire digital life behind my 4-9 point lock symbol? Or worse, a fingerprint?


  • For data transfer to the display pixels, almost definitely every display uses some sort of multiplexing, but most display boards include a driver chip that does the multiplexing for you. There are a couple of persistent display techs (only send data when you want to change what is displayed) like e-ink, but there’s also a LCD version that I think Sharp just released, that doesn’t have e ink’s slow update rate or persistence tendencies. Both are much more expensive than your $free.99 display.

    Very cool that you got it working! I also found a disposed vape and ripped out the charging board with a display like that to monitor/charge some spare 18650 batteries I harvested. I hate that the standard vape is now disposable, Lotta good stuff in there!
