I don't know what it was, but this last week was completely and totally exhausting. At least I can say one thing with relative certainty: it is not physical exertion that drains me the most. (Which isn't to say it can't - but physically, the week wasn't strenuous.)

There's an expression I sometimes use, and it's some morbid dark humor though I know a lot of depressed people would understand it.

cut for morbidity )
(If you didn't click through: I've been feeling pretty badly - not suicidal, but not exactly loving life - and please remember my gift for understatement!)

Last week, I was asking myself when was the last time I didn't feel this way, and I couldn't remember. Months - since the beginning of the year for sure. It feels like eternity.

The good news is, in the short term, I now know that plenty of rest will help, and I've certainly earned some downtime. I finished up my first documentation project at AWS, and I'll see what they think, and I have some ideas for more.

It was kind of neat. I wanted to write up how to control IO on SQL Server. In RDS (where I work) we supply provisioned databases, and they have one serious weakness: they have only one volume - one pipeline for data. This isn't insurmountable, and it's not intrinsically bad, but to reduce contention on anything, the best way to do it is make more of them. With database engines, multiple data paths are considered a very good thing.

There are ways to control most IO traffic, but to explain why they're important, a person needs to know a bit about indexes and file storage in SQL Server.

Well, we have a Wiki for knowledge sharing, and Wikis are good for linking things - so I now have three articles, one on databases and file storage, one on indexing and indexes, and one on IO control. And while I'm exhausted and know I haven't got a lot of energy to spare, it feels really good. I accomplished something, and something more permanent than just helping one customer get through one question/problem/situation. So, that's something. I'm feeling a lot more positive about life and it is, thank god, the weekend.

Here's hoping life is treating you all well.
