A String is not an Error

A String is not an Error

Why Error Handling?

  • Default behavior for programs is to terminate on an error, or enter the debugger
  • Terrible user experience

Why Handle Errors?

  • Gracefully Handle Errors (retry connections, re-prompt for user input, etc)
  • Non Local Control Flow (Display error messages and screens)

Screencapture and animated gifs

Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

  1. Launch quicktime player
  2. do Screen recording

PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Exponentiation Operator: **

Exponentiation Operator

Performs exponential calculation on operands. Same algorithm as Math.pow(x, y)

  • Commonly used in albegra, geometry, physics and robotics.
  • Nice to have "inline" operator

Prior Art

  • Python
