If you haven’t read this book, I highly recommend it. I discovered it in high school and finally purchased my first copy at the now-gone Duthie Books in Kitsilano. Without going into the details of the book, the author uses a simple Peano arithmetic called Typographical Number Theory (TNT) to illustrate some of his points. An example…
I’ve been interested in HTML parsing for a while now. There are a number of reasons to do this, such as: Validating that what claims to be HTML, is HTML Finding every style sheet and script in an HTML file Pretty-printing Syntax highlighting Linting Translating between markup languages, for example generating JSPs from PHP, or…

I got interested in building my own wireless point after seeing some of the wireless firmware issues like this. Besides, I’ve always been interested in embedded devices and FreeBSD. So, the first step was a device. I chose to use a Wandboard. I’m a committer to Crochet-FreeBSD, so I built out the device support for…
