more updates to my system tuning info. apache listenBacklog, and various useful urls added.

On a day when we release three very common package updates, we managed
to have a turned-out-to-be-minor-but-looked-grave database issue that was
causing TheReallyBigTable to miss the useful index and hit a useless one instead.
The db whiz kids seem to have found a fix thankfully.

Currently in the process of spamming (er, sending out requested opt-in notifications…)
to about a gazillion people.

I’m in the mood to make hummus again. I don’t know why.

Other than that, a boring day.
