Here I was thinking this was some sort of urban myth caused by superstitions in an age with less abundance of easily accessible tech information. Guess I owe my dad an apology now.

It looks like you're not the only one! From the comments on the top response: > "If true, I owe some baby boomers apologies for things I said about 20 years ago"

I'm in your situation, I'm so impressed!

Me too. What a humbling slap-in-the-face, no? Sometimes when an idea sounds silly, and comes from a less technical person, one might disregard it even though it's easily testable/provable.

    One thing about the famous "500 miles" post that I realized doesn't make sense: ---- An odd feature of our campus network at the time was that it was 100% switched. An outgoing packet wouldn't incur a router delay until hitting the POP and reaching a router on the far side. So time to connect to a lightly-loaded remote host on a nearby network would actually largely be governed by the speed of light distance to the destination rather than by incidental router delays. Feeling slightly giddy, I typed into my shell: $ units 1311 units, 63 prefixes You have: 3 millilightseconds You want: miles * 558.84719 / 0.0017893979 ---- But surely for Sendmail to register a "connect" with a remote SMTP server would require at least one (or many?) round trips to the remote server, so one-way speed of light time doesn't seem like it would really be relevant. Am I missing something?

      Possibly the introduction wherein the author says: "The story is slightly altered in order to protect the guilty, elide over irrelevant and boring details, and generally make the whole thing more entertaining." If memory serves he goes into further detail about the alterations and some common objections to the story in his FAQ: https://www.ibiblio.org/harris/500milemail-faq.html https://www.ibiblio.org/harris/500milemail-faq.html

      I believe one version of this story explains that the math (and the situation) has been simplified for the sake of this story in order to make it readable. Makes sense, I can share this story to people without any computer knowledge, but something explaining how connections are established would be wholly incomprehensible to them.

      The speed of electricity in copper is lower than the speed of light in a vacuum. The speed of light in fiber optics seems to be even lower.

  On that subject, don't make fun of people who paste screenshots into Word docs and email them. On Windows 95, that was a really good idea! MS Word was one of the few ubiquitous tools that would compress images, and certainly one of the few that people could be counted on to know. MS Paint didn't support PNG until Win98, and even then wouldn't do it by default. If you didn't go via Word, chances are you'd be emailing a 900kB BMP at a time when people used 28.8k modems to access Hotmail accounts with 2MB caps.

    Also, MSPaint on Windows XP adds ".PNG" extension in uppercase which is also annoying.
