# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.
#
# Also see:
# - imv from renameutils
# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)

# We use PROMPT_COMMAND and the DEBUG trap to generate timing information. We try
# to avoid clobbering what we can, and try to give the user ways around our
# clobbers, if it's unavoidable. For example, PROMPT_COMMAND is appended to,
# and the DEBUG trap is layered with other traps, if it exists.

# A bash quirk is that the DEBUG trap is fired every time a command runs, even
# if it's later on in the pipeline. If uncorrected, this could cause bad timing
# data for commands like `slow | slow | fast`, since the timer starts at the start
# of the "fast" command.

Steps to Terminal Enlightenment on a Mac

Hopefully you'll Live Long and Prosper, so I don't mean terminal as in "you gonna die". This is a somewhat opinionated article on configuring a macOS machine with:

• iTerm2
• Z-shell
• Oh My ZSH! (mostly obsolete now)
• Powerlevel9k
• Nerd Fonts, which are Powerline-derived fonts, particularly my favorite - Hack Nerd

'Users hate change'

This week NN Group released a video by Jakob Nielsen in which he attempts to help designers deal with the problem of customers being resistant to their new site/product redesign. The argument goes thusly:

1. Humans naturally resist change
2. Your change is for the better
3. Customers should just get used to it and stop complaining

There's slightly more to it than that, he caveats his argument with requiring you to have of course followed their best practices on product design, and allows for a period of customers being able to elect to continue to use the old site, although he says this is obviously only a temporary solution as you don't want to support both.
