Words of MLK

If you don’t have anything nice to say, perhaps you shouldn’t say anything. Nevertheless…

The arc of the moral universe might bend toward justice, but that arc is evidently quite long [MLK speech, Unitarian origins]. I once lived in times in which its bending was manifest, but times have changed. 

Today plain spaces are made rough. The straight are made crooked. Valleys are filled, and hills and mountains raised [MLK speech, Isaiah 40:4-5 origins]. The twentieth century grows distant in the rear view mirror. The arc is bending the other way.

Call Me Pop

It’s not that I worked at NASA. It’s not that I was a software architect. It’s not even that I have been a teacher. The accomplishment of my life is my son, Ben. And now he and Sam are doing that themselves (despite his declarations years ago that he a “breeder” would not be).

Lila (5 pounds 10 ounces) arrived January 6. (What a riot!)

That makes me a grandfather. So just call me “Pop”.

Krugman: America Has Become a Digital Narco-State

Imagine … if the United States were to legalize … heroin… [It] would quickly become a huge, multibillion-dollar industry [and] would become a significant part of GDP, even though heroin harms and often kills those who consume it. Given the increasingly naked corruption of U.S. politics, the heroin industry would be able to purchase massive political influence, enough to block any attempts to limit the harm it does.

If this story strikes you as extreme or implausible, here’s what you should know: replace “heroin” with “social media,” and this is a description of actual events.

Or replace “heroin” with “plastics” or “fossil fuels” or “opioids” or …

Airbus vs. The Sun

Sun, 30 Nov 2025, 12:46 PM (-06:00) Creative Commons License

Search around a bit. Look for the terms “Airbus 320” and “radiation” and “grounding”. 

What you’ll find in most cases is a pseudo-technical summary of the so called “root cause” of the problem that led to the recent emergency Airbus 320 recall. It’s the sun, you see — solar radiation corrupted the flight computers. But search a bit more. What’s the prescribed fix? It’s to revert to the previous version of the flight software. 

Wait. What?

Reverting the software eliminates solar radiation corrupting the avionics!? Of course not. Reverting the software restores a capability that the avionics previously had: to be resilient to bad data. 

And so, it seems, it was not the sun. Not the radiation. Not corrupted data. These are proximate causes. The problem stemmed from a software update. Yet even that is a proximate cause. Don’t blame the update. Software mistakes happen.

No, this was a faulty update to critical flight software that didn’t get caught during testing. And so the root cause was a breakdown in the testing process.

The sun is off the hook.
