Controlling your Caps

leave a comment »

I’m not sure when I started using my Caps Lock as a third Control key.  I seem to have had a registry file to do so for quite some time, so it probably dates from before I started using Linux as my primary OS.  The keymaps file that switches it on my LFS console is at least seven years old.  The file backing Gnome’s control panel setting has been stored in one of my home directory repositories for over four years.  It’s been long enough that I honestly get surprised when I try to use someone else’s keyboard and find that a shortcut doesn’t work.

Stacking Considerations

leave a comment »

I’ve mentioned RPL before, as the language of my high-school calculator.  For some odd reason, I didn’t mention that it’s a stack-based language, like Forth.  I’m now dealing with another stack-based language, which makes me wonder whether that high school experience is helping me keep it all straight.

Cooking as the Third Party

leave a comment »

An obscure bug with an obscure solution was brought to our attention one weekend.  The next weekend, we were informed that the same symptoms were displayed by another browser.  Safari rejects our third-party session cookies even with a P3P header, requiring much more drastic measures.  So drastic that I’m not sure which route we’ll take.

Test-Driven Goals

leave a comment »

At one point, I was asked to give a talk about goals.  I don’t set personal goals very often, and until this blog, hadn’t deliberately followed through on many, so it took me a bit to find something to honestly say.  That’s when I realized that unit tests, like the ones I had been writing for both personal and work projects, are themselves a kind of goal.

Virtual Apache

leave a comment »

I feel foolish.

I spent far too long setting up a virtual host on a new Apache server.  I’ve maintained such a system before, so it shouldn’t be a problem, right?  But my new site file simply wasn’t working:

Obviously Controllable

leave a comment »

Think about your shower head.  Is it adjustable?  If so, is it obviously so?  Most shower heads need adjustment only when moving in, so designers frequently prioritize aesthetics, minimizing or hiding the ability to do so.  However, a few are destined for hotel rooms or other places where they could be used by a wide variety of people, but only a few times each; for those cases, having an oversized knob makes the whole thing much friendlier to use, even if it doesn’t look quite as fancy.
