Adding TLS to your S3 static site with Cloudfront

Step n+1 in the process of moving to a static site (steps 0 through n are right here) was to enable TLS encryption. Gone are the days when you had to fork out squillions of dollars for an SSL certificate if you wanted that fancy padlock in the address bar; these days, Amazon Certificate Manager hands them out for free. If you’re not wedded to the AWS ecosystem, the good folks at Let’s Encrypt hand out free certs as well, with their Clarkes-Third-Law-level magic configuration software.

The Old New Thing: Turning Static

Fifteen years ago, when I spun up what became, Movable Type was the de rigeur blogging platform, the CMS before any of us even really knew what a “CMS” was.

That… well, that didn’t go so well, did it? Now that I’ve finished the book project (of which more later), I decided to pick up The Party Decides to see how well it held up after Trump.

40-Times-Leveraged Short Volatility Trade Goes Horrifically Wrong For Everyone Involved
