Events

I just pushed a minor update to the Daily Parker's blog engine, the thing that you're looking at right now. I fixed a couple of performance bottlenecks, so I hope the experience is a bit faster. (You can always check out the release notes for a summary of what I've done.)

On 28 January 1986, 40 years ago today, the Space Shuttle Challenger exploded 73 seconds after launch from Kennedy Space Center in Cape Canaveral, Fla. Six astronauts and a teacher from New Hampshire died when the crew cabin of the orbiter impacted the Atlantic Ocean more than three minutes later; most of them were likely conscious and aware at the time.

On January 27th, we still have 5 weeks until spring officially begins. The forecast doesn't predict any above-freezing temperatures as far as it can see, and we've already had 10 days below freezing in this seemingly endless cold snap.

Oh, look, the temperature is going up! It's almost all the way to -15°C (5°F).

Now that the Calendar feature works, I spent an hour today writing a utility to count all the public blog posts by month, and to give me a cumulative count. It turns out, most of my posts exhorting big milestones, like the 5,000th or, more recently, the 9,000th, were off by a few weeks.

Yesterday morning, Immigration and Customs Enforcement—who have no jurisdiction over US citizens—murdered another US citizen in what witness videos clearly show as a depraved act involving at least two shooters. Alex Pretti, the murdered ICU nurse who tried to shield other observers from being assaulted with chemical irritants, was unarmed and subdued when ICE agents shot him at least 8 times.

The temperature at Inner Drive Technology World HQ dropped below freezing at 8:52 pm last Friday and will probably not go above freezing until at least February 6th. We have had three-week stretches below freezing many times, and every one of them has sucked. I lived through the longest below-freezing stretch in Chicago history, the 43 days between 28 December 1976 and 8 February 1977. I also lived through the record low of -33°C (-27°F) on 20 January 1985, the earliest first freeze on 22 September...

After bottoming out at -21.3°C (-6.3°F) around 8:30 this morning, the temperature has skyrocketed to -18.7°C (-1.7°F) a few minutes ago. I decided to walk to my optometrist appointment, 12 minutes there and 13 minutes back thanks to a red light, which wasn't too bad in my swaddling. When I got back, Cassie lasted just over 4 minutes before bolting for my front door. Smart dog.

The temperature at Inner Drive World HQ has slid down to -20.9°C (-5.6°F), the coldest temperature we've had in two years. O'Hare shows -23.9°C (-11°F), which is colder than the low temperature in January 2024; the last day it got this cold was 31 January 2019, when it hit -29.4°C (-21°F).

In my last post on how the Daily Parker blog engine works, I talked about the fundamental abstractions that I built it around. Today I'm going to talk about the code some more, but more concretely, by explaining how the application decides who can see or do what. I'm a little proud of this design, to be honest.
