This reminds me of an old project. Explain all the bits that are communicated and computed across all APIs involved, when a user presses a key, and a set of pixels appear on the screen spelling "a".

Did you ever get around to finish that? I'm curious.

About twenty years ago, I was able to do something pretty much like this for typing "cat file" - e.g. syscall interface, tty drivers, network protocols, filesystems, SCSI plus pervasive things like schedulers and memory managers. I can't do that any more, though, because I've become more of a storage specialist and some of the parts I haven't kept with have changed immensely. Also, some of the implementations of those parts in Linux are frankly insane and I no longer enjoy panning through a ton of dirt for a few flecks of gold.

  I wouldn't mind seeing that, even for a 20 year old system.

    Ditto. I'd still love to see whatever tidbits are available if only for historic reasons, which in itself is quite valuable. Might be also fun to see a before and after if someone else does an up to date version too.

Could someone point to a resource that would explain what happens when Im viewing a website on my phone driving down the highway? What does my cellphone send to the nearest cell-phone tower? What does the cell-phone tower send to the phone company servers? How do they tie back together packets coming back from https://news.ycombinator.com https://news.ycombinator.com back to my phone?

  If it's you driving, you put down the phone and pay attention to the road. :)
