Where did all the HTTP referrers go?
Good (and bad news): the general consensus in the web developer community is that any and every website should be HTTPS by default. Why? HTTP by itself isn't encrypted, leaving it open to eavesdropping, message tampering, and man-in-the-middle attacks. HTTPS, if you use it consistently , prevents these issues.

Solving my truck’s TPMS sensor problem with the help of an RTL-SDR dongle
This post is going to be a bit different from my usual posts. It’s still about computers, but it’s about a different type of computer: the computer modules in my 2009 Dodge Ram 1500 pickup.
