  • Vi is meant for old school and modern terminals. Ctrl+S or Ctrl+C had very particular purposes in software control flow. With Vi you can communicate via SSH on almost any unix file system. It’s basically a universal editor that doesn’t require a mouse or a lot of keys on a keyboard. You can get away with just a subset of the ASCII set.

    So for one, it’s kind of like having a backwards compatible piece of software that exists on almost any system you might need to remotely control via a keyboard with no GUI.

    For two, once you do learn how to use Vi/Vim/Emacs, you’ll be far faster at typing. It has several useful tricks for automating typing (faster copy/paste, copy/paste n-times, jump around lines/chars, go-to lines, search via Regex, etc.) which are particularly useful in a programming context.

    Generally, it’s worth a developer spending at least a day or a week typing only in Vi for programming. Yes, you’ll be slow and clunky. But the moment you have to SSH into a server and make meaningful changes to a file, you’ll be happy you spent the time.




  • It’s pretty simple. Medical devices should have certain expectations for time and support. This happens in other industries all the time. Product support has to be guaranteed. And if you can’t guarantee product support, make your software open source. That’s not a law, just a “I’m not an asshole” placeholder. Open source schematics and software won’t fix everything, but it shows good faith effort to help people fucking not go blind.



  • Time is relative. So, the electrons might experience a different “time” because they are moving closer to the speed of light, but they cannot traverse further in time. The twin paradox is interesting because humans change as time goes on. The internal changes a human experiences as they experience time dilation is what we really are measuring. If the twins were both frozen in time, we wouldn’t really care that they experienced different time references during their trip.

    The electrons are basically “frozen in time” in this regard. The information they carry isn’t changing in their relative frame. So the end result isn’t super interesting. If the electron changed over time - and we moved it close to the speed of light - that change would be relative. The information we sent would be different than when it arrived.

    In other words, they do experience different time frames than something 0.00000001c, but since they don’t change at all it’s not really meaningful that they are - perhaps - less “aged” by the time they reach their destination than we are.
