According to the Jargon File, version 4.1.2:

'''Right Thing (n.)'''

That which is compellingly the correct or appropriate thing to use, do, say, etc. Often capitalized, always emphasized in speech as though capitalized. Use of this term often implies that in fact reasonable people may disagree. "What's the RightThing for LISP to do when it sees (mod a 0)? Should it return a, or give a divide-by-0 error?"

See also WorseIsBetter, where a different definition of the RightThing is made, namely the MIT/Stanford approach as opposed to the NewJersey (C/UNIX) style pragmatism (called WorseIsBetter).  In this sense, trying to achieve the RightThing is a sort of BigDesign or BigDesignUpFront, which should be avoided (YouArentGonnaNeedIt).

''The IncompatibleTimeSharingSystem, whose PcLosering was the canonical RightThing
in RichardGabriel's GoodNewsBadNewsHowToWinBig, isn't BigDesignUpFront
by any stretch of the imagination.''

Untrue. Adding PcLosering to Unix would have meant making guarantees about the behavior of every single system call without exception, including that any partial work previously accomplished would be seamlessly tracked by the kernel. And this, on a PDP-11 whose hardware couldn't even recover from an interrupt in the middle of a partially executed instruction!

But hardware issues aside, still it '''is''' a big deal to make such guarantees for any and all current and future system calls. PcLosering is arguably the RightThing, sure, but don't gloss over the difficulties.

You can do something the quick and dirty way, or you can do the RightThing and do it properly.  Sounds like CantDoRightRightNow.

Used by the advertising campaign in Australia that ran for about 10 years and changed people's attitudes towards rubbish - Australia is much cleaner than it used to be. The advertising slogan was ''Do the Right Thing'', but without the jingle it loses something in the translation.

''So IncrementalGarbageCollection is the right thing.''
