Last two years were 775 kWh and 740 kWh. This month’s bill is for 480 kWh. Down 295 since 2007, 260 since last year. Total savings from last year for the June bill is $17.22. I have the windows to thank for this, I think. I need to make a few more tweaks to the attic (insulation) and a replacement for my aged sliding glass door, and I’ll be even more efficient. I’m also considering replacing my washer and dryer with a Thor all-in-one device that will shave my wattage as well.

Say it takes 5 parameters. Through analysis tools, you find out you’re always calling four parameters the same way, and only the 5th changes. Let us also assume that the code is not under your control.

Would you:

  1. turn the parameters in your calls into constants
  2. mass search-replace throughout your project when the owner of the function changes its behavior or inputs
  3. “wrap” the function in your own, renamed function to future-proof your project and mitigate change
