Industries commoditize over time, delivering similar products at similar prices resulting in low profit. Like entropy, this is the inevitable fate of a company, unless it exerts intentional force to the contrary. Moats are this force, and your strategy must identify how to create...

Pretty recently, I was troubleshooting a performance issue in a production Rails app backed by Postgres. There was this one class of query that would get slower and slower over the course of about an hour. The exact pathology is a tale for another time, but the investigation led...

Indeed, there's plenty to go around, thanks largely to all of you. But the fastest way to make the numbers better is to stop feeding and sheltering people and their families. Nothing personal.

“The market is tough” is something many juniors hear today. people are frustrated. graduating after 3-4 years with a CS degree is not easy. They graduate only to find out nobody wants to hire them or even move forward beyond the initial screening.
I’ll be real with you. there’s...

Chris Wellons posted a good review of why large chunks of the C
library are terrible,
especially if you are coding on Windows - good fun if you like staring
into the abyss. He followed up with let’s write a

more positive way. I was also pleased to learn...

Polynomials can be represented in various forms. The most common ones are
those I call the "sum of powers" (for example f(x)=ax³+bx²+cx+d) and the
"root factors" (for example f(x)=(x-r)(x-s)(x-t), where r, s and t are
the roots). The process of transforming the former into the...

I've been sticking to a sketching routine recently: every day I draw at least once face.
Faces are different for me than any other kind of drawing. Somewhere in the process the face looks real enough for me to recognize it as a human being, if it's a good drawing. About 30% of...

When I wrote about App-pocalypse Now in 2014, I implied the future still belonged to the web. And it does. But it's also true that the web has changed a lot in the last 10 years, much less the last 20 or 30.
