It Was Trump, Not Antifa
Dear friends of mine who support Trump:
Your “it was Antifa” claims have all been disproven, but it did buy you an additional 12-24 hours to come up with some other cover.

Die Hard is anti-American propaganda
[NOTE: This is a rough draft of a rant.]
Is “Die Hard” a Christmas film? Who cares!
Die Hard is anti-American propaganda. It is full of lies that give people the impression that the U.S. government can’t do anything right. Anyone raised seeing that movie will grow up with misconceptions about the government that are harmful to our society.read more

The long road to publishing a scientific paper
Here’s an infographic from Kathryn M. Everson.
I didn’t write it, but I want to make it available outside of social media where it is hard to surface. (I hope she doesn’t mind.)
What I love about this is that it explains that real science is slow and takes time. Hollywood movies portray science as a series of overnight miracles; Star Trek shows Jordi inventing entire new categories of science by the end of a 60-minute episode. Real science takes years. Real science is boring 99.99 percent of the time, punctuated by amazing discoveries. Real scientists are underpaid and over-worked.

Refactoring a Loop That Was Trying Too Hard
I fixed bug last night.
The bug was difficult to fix because the code was so complex. I wasn’t really able to fix it until I simplified the code. Once the code was simplified the bug was easy to fix. While doing this I found an anti-pattern that I now call “One loop trying too hard”.read more

An open letter to Uncle Bob about "Defund The Police"
You’ve tweeted that you feel “defund the police” is a terrible policy. I hope to change your mind.
Ignore the name. It is imperfect. In software engineering terms, “defund the police” is similar to the strangler pattern.
For the non-engineers reading this, TSP is a reasonable, pragmatic, and down-to-earth way to slowly replacement an old system with a new system. The name is terrible… I would have called it the warm hug of gradual change.read more
