I work for Red Hat on the Fedora Linux distribution. Before that, I was a sysadmin in the Academic Computing group at Harvard School of Engineering and Applied Sciences. Photography is a hobby, and my main goal is simply documentation of my family life.

For some reason, most of my favorite answers here have something to with the geometry of photography, whether in composition, in exposure parameters, or angle of view. And hopefully in a way that makes it clear and interesting even to the non-geek:

But it's not all geometry!

If you're a Pentax user, you may be interested in my definitive guide to Pentax hot shoe flashes and compatible 3rd-party options. It's no longer updated, but still has lots of good information. (If you'd like to take over, let me know!)

comment What is the cause of this non-uniform bokeh effect?
So, is the characteristic cat's eye shape of the highlights due to the vignetting as explained in @MichaelT's answer? Is it possible to get the "swirly" look without vignetting — e.g. field curvature alone? Conversely, can that look occur when there's just vignetting and no field curvature?

comment Can I make my Nikon DSLR put photos in separate folders per day?
For what it's worth (not much, I suppose, but in case this is a really important feature to someone and they can't live with your suggestion for doing it on "ingestion", there's no way on this Nikon model, but it is possible on some other brands of DSLR.

That's an autocorrect error. But car or cat, the comment is the same.

revised How can I photograph a toy against a white background, leaving the toy in shadow?
This not really a still life in the traditional sense, as there is no arrangement
