HN has very little understanding of networking in general.

  Programmers have very little understanding of computers, in general. They'll think hard about a beautiful unrealistic idealisation of the problem, and/or treat a software abstraction as if it's the underlying reality, e.g. (of the latter) thinking networking starts with HTTP and languages start with JavaScript.

    Agreed, except IME this is "junior web developers" rather "(real) programmers" in general.

      Mel wouldn't. But Mel isn't programmers.

      Just read the contract from the other side! If focusing on idealistic software abstractions instead of the problem is bad, the implication is that focusing on the problem is good. If treating a software abstraction as the underlying reality is bad, the implication is that looking below it to the actual underlying reality is good.

  It does seem to be a surprisingly common blindspot of programmers in general. I strongly recommend programmers learn it, it can save a lot of headaches in system architecture.

    Any recommendations on a good path to learn this — curious if you have any personal, opinionated thoughts on this.

      Buy some cheap computer, pop in a few NICs, setup a FreeBSD or OpenBSD gateway, including DNS and some other goodies. And by cheap, any $10 relic will do. You’ll find their manuals very informative.

        I'll add looking up the ipv4 and ipv6 specs on www.rfc-editor.org .

  Especially since most machines will just WORK with auto-assigned magic weird IPs and you'll actually be able to share files directly via the OS if you do this, no need for Linux netcat tricks at all. Now I still remember when target disk mode over ethernet was being talked about.
