kludge

But I didn't do anything to the soon-to-be-mutilated MAV today. Today was all about system checks. Now that I'm back in contact with NASA, I have to go back to being all "safety first."

Usage Note: Today, kluge and kludge are often used as alternative spellings of the same word, although a distinction in usage can perhaps be detected: in the UK, the connotation of kludge is almost wholly negative (as befits its alleged derivation), while US usage of kluge, following its alleged German derivation, admits some fondness or admiration for the cleverness or functionality underlying a working klu(d)ge.
英国と米国でニュアンスが異なるのですね。ちなみに作者は米国人なので良い意味で使っているのでしょう。
