As has become abundantly clear recently, COVID-19 isn't going away; in fact, it's striking more and more of my friends and family who had successfully avoided it for years. At this point, we have ample evidence that masks work to drastically reduce the spread of COVID; however, none of the local, state, or federal governments are willing to take the low-cost, high-return step of requiring mask usage in public settings, so most people just don't bother. The fact that I'm usually the only one wearing a mask in any given space, combined with the increased contagiousness of the Omicron family …

After more than two years of successfully dodging it, COVID-19 finally hit my family the week. On Tuesday my wife woke up with a migraine, which isn't unusual for her; on Wednesday morning, she woke up with a low (100.4°F fever) and we belatedly realized that she might be sick. She took an antigen test¹ and the TEST line turned blue basically instantly.

Shit.

Quarantine ensued. Isaac (our son) has been home from school² and we've all been cooped up on the property for the past few days.

So far, Isaac and I have continued to …

Yesterday, California released their Digital Vaccine Record system for securely verifying residents' COVID-19 vaccination status. I took a look at it and thought I'd write up my findings here. At a high level, the DVR consists of a QR code which contains a cryptographically-signed assertion in JSON Web Token (JWT) format. I'll walk you through how to get one, how to decode it, and what it contains in the rest of this article.

Getting one of the tokens is pretty easy; you just go to the Digital Vaccine Record website and put in your name, date of birth, and the …

• I was maybe a little tired yesterday afternoon
• Yesterday evening I had an elevated temperature of 99.7°F, but no clinical fever
• This morning my arm feels like I lost a really intense game of Punch Buggy

I know the pandemic is nowhere near over and people are dying by the thousands around the world, but …

As of yesterday morning, I've gotten my first shot of the ModeRNA¹ COVID-19 vaccine!

I'd been trying to get an appointment since Berkeley opened them up to all adults on April 9th, and had no luck until 3am on Friday morning, when I managed to get one of the spots released by the CVS near my house (they were all gone a few minutes later). I was surprised to find when I arrived at CVS that, despite the intense competition to get vaccinated, supply is so tight that they were only being issued 10 doses (one vial) per day …

There are trees growing out out of the sand at the park near my house, closed for the last few months due to COVID-19. What a weird world.
