LOL, one little edit in the Threat Driven Software Development book and I'm magically transported back to 2007 :)
Once again, I am reminded that the quickest way to turn a task from something you actively dread to something you actively look forward to is to automate it.

Not sure how we went from plain, straightforward words to LinkedIn speak but now you can use Kagi Translate to fit right into that crowd:

Playing with a cool UX approach to help you study and practice chess opening theory.

1) Click on a sentence

Ok, this is cool. You have 10 things with various features (think: price / quality / speed or CVSS / known exploited / time unpatched) and you want to use a formula to put them in order. You can compare any two and probably make a good call, but you don't want to hand-craft a formula because that introduces bias.

There is something called Bradley-Terry Logistic Regression that is designed exactly for this. Here's an implementation, even letting you compare among multiple evaluators to see where your value systems may differ.
