If you’re reading this, it’s running on a completely different platform than it was a few weeks ago. This blog spent its entire life on Blogger – from the first post back in September 2019 right up through early 2026. It served me well, but I’d been wanting to own more of the stack for a while. This post is the story of that migration: why I did it, how it works, and – more honestly – all the t...

Certification Authority Browser Forum (CA/Browser Forum) is “a voluntary gathering of Certificate Issuers and suppliers of Internet browser software and other applications that use certificates (Certificate Consumers).” This group has determined that SSL/TLS certificates will soon be required to expire every 47 days (or less). Compared to the industry standards of even a few years ago, this is ...

TLS It’s been 4.5 years since I last wrote about the state of TLS and secure cipher suites. A lot has changed in that time including some updates around TLS and cipher suites, so I wanted to provide an update while it has been on my mind. First and foremost – TLS 1.3 is gaining ground. Qualys’ SSL Labs shows that even as of June 2025, 75% of sites surveyed supported TLS 1.3. This is great new...

I enjoy learning about time. It’s fascinating to me how we’ve globally agreed that time will be different for various parts of the world, how we are going to represent that time difference, and making sure that we know the most accurate time possible. This isn’t just important to make sure you’re on time for an appointment, but it is surprisingly important in the technology we use every day. H...

Several years ago I had heard about the concept of a “RetroPie.” A Raspberry Pi loaded with hundreds of classic games that can be connected to custom home builds, arcade systems, or just a normal TV. The idea always interested me as I’m a fan of ’80s style arcades, but primarily from the perspective of getting this to work on a computer about the size of a credit card. I recently decided it was...
