Charles Choi has been writing a bunch of nice little apps lately—more than I can cover. His latest, Aquí, is sort of a niche application but is potentially useful for more than just its intended use.
The back story is that Choi really likes the sunrise-sunset command in Emacs that tells him the times that the sun rises and sets. The problem is that sunrise-sunset requires that you first specify the latitude and longitude of where you want to know the times. The standard way of doing that is to record them in your init.el, which is what I do. Choi, however, travels with his laptop but still wants to know when the sun is coming up or going down. There’s no automatic way of setting the information so he wrote Aquí to provide it. The only downside is that it works exclusively on the Mac platform.
Once installed, all you need do is call aqui to set all the appropriate information. I hardly ever travel these days so I wasn’t going to bother but it’s easy to use and can give you your current latitude and longitude as well as your address so I thought, “Why not?”. After I installed and ran it, it gave me my exact address as well as my latitude and longitude. That might sometimes vary a bit depending on the vagaries of GPS but it’s certain to be close.
If you decide to try it out, be sure to take a look at the user manual so see what commands are available. Mostly, though, you’ll just need to run aqui. Also be sure to check out the installation section because you need to install a shortcut. That’s just a matter of clicking on a link in the manual but Aquí won’t work until you do.
