Once all records are paged, the headers get dropped and my program errors out… Read More How to handle "The given header was not found" when paging records in c# API GET request?
As part of a code review a colleague recommended using a type rather than an enum. Whilst making the changes we found an issue neither of us expected.

However, after testing we… Read More Template literal throws errors in some scenarios but not others

I have an enumeration in C as follows: enum menu { PASTA, PIZZA, DIET_COKE, MOJITO, }; Since I haven’t explicitly mentioned the integer values corresponding to these elements, they are assigned values 0,1,2, and 3 respectively. Say I decide to add another 100 or so items to my enum. Then is there a way to… Read More How do I access the an element in an enumeration by the associated number in C?
I see that MDN Web Docs now lists the :has() pseudo-class among others, but is there something similar to :has-text() from uBlock Origin? span:has-text(Promoted by) { display: none; } uBlock Origin has both, so I’m wondering whether I have simply overlooked something on MDN. >Solution : Unless I’m wrong, this is not possible in CSS.… Read More Is there a native CSS replacement for :has-text()?
