Data over radio. That I can't hear. But just... exists. In the air. We're surrounded by it. Even when there is near silence. Like invisible 0s and 1s just flying every which way.

Radio waves in general as a science concept, let alone a computer science concept, is absolutely miracle shit.

@nixCraft

#OOP... because I never got around to learning it in the 90s & naughties, and it now seems to be somewhat deprecated in newer languages.

The hype train isn't kind to its older destinations. 😅

@nixCraft Given how fast modern computers are, they are still impossibly slow for big problems.

Ex: Traveling Salesman problem, cracking a 16 digit password, etc...

It's more or less this fault that makes passwords and cryptography useful.

@nixCraft #DOCSIS #HFC #CableModem

It took a SINGLE copper wire surrounded by dielectric and a wire mesh which was originally designed to carry analog audio signals. Now with #DOCSIS4 we can get 10GBps of degrees and ~7GBps ingress. That same Layer 1 single wire can now care thousands of audio streams, video, data, etc

@nixCraft

That after clicking to open a web page that request went from my computer across the globe to the destination server and back in basically less than 1 second.

@nixCraft Abstraction.

I am equally amazed by the graceful simplicity that results from a good abstraction and by the horrible mess that results from a bad one.
