I was going to spend the weekend writing, but instead ended up doing about 48 hours worth of backend maintenance and new content writing for my Primer on Bézier Curves, so: have a link! There's a new section on how to implement exact Bezier fitting (with one degree of freedom), a "what's new" section in case you've seen this thing before and just want to know what's new since the last time you looked, and of course it still has all the delicious Bézier curve content that was up already.
Questions, comments, hit me up here on HN, the disqus comment thread on the page, or file a github issue (if you find any bugs: seriously, file an issue, bugs don't benefit anyone O_O)
