Wouldn't it be better to perform a server side lookup to avoid leaking the full list of currently used Barclays numbers in plaintext to fraudsters?
The fact that there isn't any user input sanitization makes me inclined to believe that this implementation decision may not have been well-thought-out (which I'm guessing was the author's point exactly)
Hi Andy: if you see this, I'm the other 4d polygon renderer! I read the kubernetes whitepaper after RC and ended up spending a lot of the last year on it. Maybe if I had asked you about working with Borg I could have saved myself some trouble. Glad to see you're still very active!
