@Graham I do all my (non-DP) software updates with the CLI and looking through my shell scrollback (which I save to file) none of them have a space.
I believe OS X Server's Software Update service stores a list of all the updates since the beginning of time—I'll have a look next time I'm at my computer.
@jhfrontz The dupe you linked to isn't the best one for most of the voted posts.
Having a dozen linked questions isn't actively harmful to the site so usually we try to get things linked properly.
A quick look - we have basically the same question - why doesn't purge work on OS X as it does on Linux for 10.6 and 10.7 as well as questions that reiterate that and refine what precisely about previous answers don't help the OP.
Also, since memory management was drastically changed on 10.9 - those old questions are likely to not need new answers and we'll hopefully end up with less VM questions on the newer OS since the system takes care of itself better and is less likely to confuse people with inactive memory being replaced with memory pressure and improved swap utilization / sleep memory reductions on disk / memory compression.
@bmike -- memory management was changed or the reporting in Activity Monitor changed?
My concern about [what appear to be] repeated assertion of the same incorrect interpretation (as the basis for these questions) is that they all attract responses that include things like "use purge" and then that has to be corrected to say "you, a regular user, should never need to use purge" and explain (again) how VM works.
If they're actually performance issues stemming from different sources, I would suggest that they be edited to reflect that -- I can go around and propose edits (most notably to titles/preambles that in essence assert "I have inactive memory and that is bad") if that would be useful?
I wasn't paying attention to the dates of the original questions/responses (only to the assertions being made by folks who didn't understand how VM works).
