Wouldn't it be useful if there are separate calendars for contests and streams?

(Currently, there is a single calendar for both & there is no trivial way to block emails of new streams being added in the calendar)

Also, it does not make sense to have streams in a calendar named "Programming Contests Calendar."

 #pragma GCC optimize ("trapv") // kills the program on integer overflows (but is really slow).

This helps a lot in testing. If a solution fails on a particular test case this can help in finding the bug.
This works on my computer but does not work on Codeforces.
Is there an alternative to this on online judges?
