Concurrency, Closures, and SwiftUI on Mac OS X

Puzzlin’ Code

Okay, here’s some SwiftUI code: Why, why, do I need to prefix tipPercentages with ‘self.‘ once we’re in the third closure but not inside the second or even the first? What’s magical about this situation? I know there’s something, but nobody is saying what.

Harbinger, Party of Some

A friend pointed out this paper about, “harbinger ZIP codes.” It is fascinating! Geography as destiny, and the likelihood is that cranks live near each other. Wow.

Right Thing, Wrong Time

Cryptocurrency, quantum supremacy, imminent death of the Internet. So, Google recently announced that they’d achieved quantum supremacy. One of the things that quantum computers are supposed to be really good at is cracking crypto really fast. The past couple of years have seen an explosion of cryptocurrencies, which are one application of blockchain, which relies

Greatness Abides

Okay, so when I looked at Google news this morning, this story was in the “For you…based on your interests” section: Gremlin Brings Chaos Monkey Testing to Spinnaker CD Platform. Now, I’m a respecter of Dev Ops, but I’m not really a practitioner of Dev Ops. So I think this is cool, but the coolest

It Could Be Better

A long time ago, my housemate (who is one of the only people who reads this – Hi, Kurt!) had this great explanation for why his homework wouldn’t compile: “It was perfect, so I fixed it.” Man, that so describes every programmer I’ve ever worked with. (Incidentally and orthogonal to the point of this post,

Book Recommendations

My friend Matt Maxwell wrote The Queen of No Tomorrows and it got published by Broken Eye Books. It is totally worth buying and installing on your phone so you can read it in line at the grocery store, while you’re waiting at the doctor’s office, and any other time you have five seconds to

I Hate Your Bot

I dunno, something like a year ago, a guy I know started retweeting a client of his who was working on building a chatbot platform. Now, let’s be honest: in customer facing positions, a lot of interactions are going to be the same. People are way more similar than they are different, and so if one

Credit Where Credit Is Due

It seems to me that I’ve been seeing lots and lots of social media posts which assert that [artist | intellectual] predicted [dystopian future that looks just like one aspect of today’s world] and did it [years ago]. I have to wonder what that’s in aid of. I mean, the second half of the 20th century

Engage

I got totally burned out on social media by the U.S. election. Rather than textual posts with partisan argumentation (that’s how you spell, “civil discourse,”) Twitter and Facebook were awash in nasty memes. A month later it feels kind of like the morning after a killer party: I’m slowly looking around for cat videos and
