Data centres I used to work in back in the early 2000s had argonite gas dumps in place (prior to argonite, halon used to be popular but is an ozone depleting gas so was phased out) In the case of a fire, it would dump a lot of argonite gas

My IDE spits out a warning when I reach a certain level of complexity in a method, using Mccabe's Cyclomatic Complexity as a measure. It roughly maps with "too many if statements" in my case.

I did a very very ugly quick hack in python. Took the example JSON, made the one list entry a string (lazy hack), repeated it 56,000 times. That resulted in a JSON doc that weighed in at 10M. My initial guess at 60,000 times was a pure f
