"checked out" vs "checkouted"
View gist:7df6c8a50c04e5b80d84f28938b3e258

Should one say "Checkouted" or "Checked out"?

At the time of writing (2020), most people would agree that the latter is preferred, and that the former is either "wrong" or at best "dubious".

This will eventually change, and perhaps already has by the time you read this.

Indeed I can be fairly confident about that, much as it pains my own sense of what's "right", because there's an inevitability about regularization.

Looking back 50 years to 1970, nobody then would have even thought of saying "checkouted", much less said it out loud, for the simple reason that it was a two-word phrase, a verb and a preposition: "check out".

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

  • Plain ASCII
  • ANSI escape codes: 16 color codes with bold/italic and background
  • 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
  • 24-bit true color: "888" colors (aka 16 million)

XHow To Write Good
1. Alliterations are awkward; always avoid.
2. Prepositions are not words to end sentences with.
3. A writer needs a cliché like a fish needs a bicycle.
4. Comparisons are as bad as the clichés.
5. Be more-or-less specific.
6. All writers should never generalise.
Seven. Be consistent.
8. Don't be redundant; don't use more words than necessary; avoid being verbose, it's excessively superfluous.
9. Who needs rhetorical questions?
