Getting to space is easy. Staying in space is hard.

The reason it’s hard to get to orbit isn’t that space is high up. It’s hard to get to orbit because you have to go so fast.

The speed you need to stay in orbit is about 8 kilometers per second. Only a fraction of a rocket’s energy is used to lift up out of the atmosphere; the vast majority of it is used to gain orbital (sideways) speed.

RFC for HTTP 700-series errors

oh. my. god.

This is, hands down, the geekiest piece of humor I have ever seen. HT to @dmuth who now owes me a cup of coffee to replace the one I blew out my nose onto my keyboard.

If you, my dear reader, care to do the ‘what the hell?’ deep dive:

  1. What’s an HTTP header?
    (it’s the glue that makes all the interwebs parts work together)
  2. What are the actual HTTP response codes?
    (200 good, 404 bad, 759 – Unexpected T_PAAMAYIM_NEKUDOTAYIM !)
  3. What’s an RFC?
    (request for comments, i.e. “hey, uh, fellows, maybe we should do it this way…”)
  4. The HyperText Coffee Pot Control Protocol (HTCPCP/1.0)
    (ie, prior art in RFC humor. Please notice the honest-to-gawd URL on that one kids. Yes, the IETF like kinda determines how the intertubes work, and they have absolutely THE ugliest website.)
  5. An obscure HTTP response code joke
    (you do know to read the “alt-texts” on XKCD cartoons, right?)
