My favorite mnemonics for American vs British English
Use these weird tricks to remember which words are American English and which are British English. Linguists HATE them!
Mnemonics
Casting in C#: cast expression vs as and is operators
A cast expression like (string)foo throws
if the types don't match.
The as operator doesn't throw
and defaults to null.
The is operator doesn't throw
and ignores nulls.
Assume vs presume in English
Both are guesses. Assume is weaker (little or no evidence), presume is stronger (reasonable evidence). But how to remember which is which?

Mnemonic:
"a" (apply()) for an array,
"c" (call()) for commas.
But Reflect.apply() is better.
Mnemonic for Markdown's link syntax (and image syntax)
Was it [text](url) or (text)[url]?
Use this one weird trick to remember –
Markdown consultants HATE it!
Spoiler: it's the former since it looks like a function call.
