Show HN: Interactive Version of “Programmer's Competency Matrix”

This is... humbling. I have a range of experience programming (Web backend, frontend, DBs, GUI, embedded HAL and bare metal), and get Level 0 on most of these.

Examples - Don't know what a linked list is - Look up documentation frequently - Don't understand defensive coding - Usually ops test instead of unit test - Don't know what virtual memory / paging is - Don't know about upcoming tech - Don't know what a platform internal is - Haven't heard of any of the books - Don't read blogs

Is this geared towards programming-language designers?

There is a typo in the headerbar: "Programmes's Competency Matrix", should be Programmer's.
