Impatient? Scroll to the bottom to download. So I recently was working on a site and wanted to use CSS3 columns. But I really like how the grid system works in Bootstrap, and wanted to be able to define columns in a similar way (i.e. have different number of columns depending on the screen size). Not finding any pre-cooked versions, I decided to write my own. Strictly speaking, you don’t need Bootstrap for this to work. But I did re-use Bootstrap’s grid variables so that it breaks along the same lines that Bootstrap’s grid does. It’s also worth noting that, natively, the columns will collapse on their own if you specify a width. This method just gives you a bit more control.

Stop! Do not do this! I am leaving this here for the reference and posterity, but for a variety of reasons, I no longer recommend doing this. It is a neat hack, but tends to be a bit of a pain to live with as you end up having to troubleshoot or reinstall it every time you update pfSense or Unifi. When you can install it on a Raspberry Pi for less than $50, there's really no need to do this.I personally have switched to running this on a stock Ubuntu system that runs a few other network services in my house. This is a short tutorial on how to install the Ubiquiti Networks’ UniFi Enterprise Wifi controller software on pfSense 2.2. These directions are derived from these directions for 2.1-RC, but have been updated to work on 2.2. Note that this is a somewhat advanced tutorial. If you are not comfortable working in a Unix command line or editing system files, this is probably not the best thing you could do. But I’m putting it out here in case it will help others.

So I’ve tweaked the design of the blog a bit. There’s now a header, and all the links that were in the sidebar are now in the header. There were simply too many things being added and it was getting unwieldy having them all in the sidebar. It’s now fully responsive on all levels of mobile, tablet included! I’ve added a new page with a bunch of content I’ve been collecting on the subject of Interstellar Travel.

Here’s a tip when dealing with UILocalNotifications. If you want to schedule a notification for a specific time using fireDate, you need to apply a timeZone to the UILocalNotification object. Otherwise, iOS will intepret this as an absolute, countdown-based date based on GMT.
