Sneakily using macros In a code golf challenge, you are tasked to use as small bytes as possible. However, it's considered unacceptable in a language like C to use macros to hide code or shorten i...
Bypassing source restrictions by storing data in the file name In some languages, like Pxem, programs are usually stored in the file name and the file's contents are irrelevant. On Somewhere Else,...
What is random defined as on this site? How are answers allowed to handle random chance?

Ruby, 56 bytes ->s,i{a=[*?a..?z].rotate(i)*"";s.tr "A-Za-z",a.upcase+a} Try it online! tr is wildly useful here. Builds the tr string manually and replaces only the alphabets.

There's another type of challenge named code bowling, and I've never heard of it, or even if I did, still don't know how it works. I'm willing to write challenges on code bowling and I want to know...
