TextKit 2 – The Promised Land
After 4 years with Apple's TextKit 2: The promised 'better' text engine has unstable scrolling, unreliable height estimates, and viewport issues so bad that even Apple's TextEdit suffers from them. Good architecture, but the implementation makes it frustratingly difficult for real-world apps.

Bullfrog in the Dungeon
In January of 1995, Electronic Arts bought the prestigious British games studio Bullfrog Productions for an undisclosed sum that was rumored to be in the neighborhood of $45 million.

The Timmy Trap
This is Part 2 of my LLM series. In Part 1 , I discussed how in just a few short years, we went from the childlike joy of creating “Pirate Poetry” to the despair that our jobs would disappear. My main message was to relax a bit, as companies abuse the hype cycle to distort what is actually happening.

Swiss vs. UK approach to major tranport projects
HS2 has become a case study in how not to build infrastructure. But what if we’d taken a different path entirely? In this post, I imagine how the Swiss would have done it: starting with the timetable, not the project. It’s a counterfactual, but it’s not a fantasy.

Airbrush art of the 80s (2015)
The 80’s was a decade of many things — excess, greed, and big hair, to name a few — but it was also the heyday for airbrush art. As a teenager in the late 80’s, I desperately wanted an airbrush so I could paint my favorite band logos on the back of my jean jacket, and maybe make some money on the side painting…

"Privacy preserving age verification" is bullshit
I don't think that it's impossible for politicians, even nontechnical politicians, to make good tech policy. After all, the fact that no one in Congress is a microbiologist doesn't stop federal standards from delivering potable water (and it doesn't excuse the ghastly failures, such as Flint, MI):
