@tech I enjoyed the alt-text (Achilles riding a skateboard?), but it would not help someone understand your message.
If you can update it to read: "A picture of Achilles (representing programmers) and an arrow (representing regex / regular expressions) in his heel (his proverbial one vulnerable spot)", that might be more informative.
I enjoyed the joke; just trying to share it with more people.
Reminds me of: "There are some people who, on discovering a problem, decide to solve it with regexes. Now they have two problems."
