Programming as Theory Building - Peter Naur

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

For tmux configs: Merge deprecated/removed -fg, -bg, and -attr options into the -style option
#!/usr/bin/env python
# vim: set fileencoding=utf-8
#
# USAGE:
# Back up your tmux old config, run the script and redirect stdout to your conf
# file. Example:
#
# $ cp ~/.tmux.conf ~/.tmux.conf.orig
# $ python ./tmux-migrate-options.py ~/.tmux.conf.orig > ~/.tmux.conf

Falsehoods programmers believe about prices

  1. You can store a price in a floating point variable.
  2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
  3. All currencies are subdivided in decimal units (like dinar/fils)
  4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
  5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
  6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
  7. For any currency you can have a price of 1. (ZWL)
  8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)
