Hi! My name is TwilightSparkle, sometimes called Radioactive. The only thing I'm proud of are my friends. I will devote my life to the art of finding unnoticed but interesting things. My pronoun is she/her, though no one refers to me.

Here are some answers that might actually be worth reading, sorted in rough order of interestingness and effort put in:

• Which character to change (Cops)
• Implement a Truth-Machine
• Print X Without X (Cops), a series of answers
• Reverse stdin and place on stdout
• Tex Quotes(UVa272)
