Testing 40 shades of blue – AB Testing

Iterative Path

The title refers to the famous anecdote about Marissa Mayer testing 40 shades of blue to determine the right color for the links. (Unfortunately I am colorblind, I know just one blue.)

Mayer is famous for many things at Google, but the one that always sticks out – and defines her in some ways – is the “Forty Shades of Blue” episode.

glitch and zeit node dev env gotchas

glitch and zeit node dev env gotchas that hit me today were as follows

glitch node dev

  • glitch auto recompiles after you edit every line which can get irritating

zeit node dev

  • glitch doesnt always attach to github so NEVER rereleases for you
  • SSL_ERROR_INTERNAL_ERROR_ALERT
  • SSL_ERROR_PROTOCOL_VERSION_ALERT

workaround !

  • triple check the ANAME / CNAME and TXT dns records
  • then simply wait 20 mins and they might disappear

the BIG bonus of zeit is that you can use YOUR own domain for FREE provided you can get rid of the SSL errors (BTW i hope glitch mktg are reading this)
