It may be very out of date, partially or totally incorrect. I may even no longer agree
with this, or might approach things differently if I wrote this post today. I rarely edit
posts after writing them, but if I have there'll be a note at the bottom about what
I changed and why. If something in this post is actively harmful or dangerous please get in
touch and I'll fix it.
