Every day Hacker News titles, stories, and comments have acronyms and abbreviations I've never seen before, and I have to search for the term to know what it's talking about. I know what a parsec is, but I've never actually seen the pc abbreviation used before. At least I learn something new every day.

Barns was a particular favourite from my university years. Imagine my surprise encountering 'mb' and it wasn't millibars. Then again, I also had to deal with microhertz and nanohertz.

At least it wasn't megabytes...

Spoiler: "megabytes" are abbreviated as MB, but many people don't see to remember that SI units are case-sensitive.

		Also keep in mind the difference between MB and MiB. You almost never want MB. You usually either want MiB or Mb.
