Weird things you can buy online
It’s April Cools! It’s like April Fools, except instead of cringe comedy you make genuine content that’s different from your normal stuff.1 For example, last year I talked about owning a microscope.

Loadsharers: Funding the Load Bearing Internet People (2020)
The Internet has a sustainability problem. Many of its critical services depend on the dedication of unpaid volunteers, because they can’t be monetized and thus don’t have any revenue stream for the maintainers to live on.

Things Every Hacker Once Knew (2017)
One fine day in January 2017 I was reminded of something I had half-noticed a few times over the previous decade. That is, younger hackers don’t know the bit structure of ASCII and the meaning of the odder control characters in it.

WiFi without internet on a Southwest flight
I spent a recent flight finding out what I could do with a connection to the flight’s wifi, but without access to the internet. I was on my way home from Strange Loop, a direct flight from St. Louis to Oakland. It’s a long enough flight that I planned to purchase the $8 internet access and get some work done, but…

Why are websites requesting access to motion sensors on my desktop? (2019)
I was checking the status of a FedEx order when Brave warned me that “this site has been blocked from accessing your motion sensors”. I’m struggling to understand why a website would need that access. Do I get a different experience if I drop my device? Tip my monitor over? Spin the mouse around?

This post looks at the Closure Compiler, Google's tool from the mid-2000s for adding types to JavaScript. It looks at how its focus on minification led to very different design choices than TypeScript, and how this and a few other factors led to TypeScript becoming the ubiquitous solution for JavaScript + types.

OpenBSD PF versus FreeBSD PF
I encountered yet another discussion about OpenBSD PF versus FreeBSD PF . For those who are new to the discussion: OpenBSD developers created PF in 2001, and it rapidly improved to become the most approachable open source packet filter.

A gentle introduction to static analyzers for C
One of the great thing about C are the many fairly mature tools in the ecosystem. The bad news however is that most educational materials don't teach them and thus many beginners (and sometimes even experienced) developers have absolutely no awareness that these tools even exists.
