BuildKit: Docker's Hidden Gem That Can Build Almost Anything

https://tuananh.net/img/apkbuild-demo.png
Most people interact with BuildKit every day without realizing it. When you run docker build, BuildKit is the engine behind it. But reducing BuildKit to “the thing that builds Dockerfiles” is like calling LLVM “the thing that compiles C.” It undersells the architecture by an order of magnitude. BuildKit is a general-purpose, pluggable build framework. It can produce OCI images, yes, but also ...

Some silly Z3 scripts I wrote

As part of writing Logic for Programmers I produced a lot of “chaff”, code samples and sections I wrote up and then threw away. Sometimes I found a better example for the same topic, sometimes I threw the topic away entirely. It felt bad to let everything all rot on my hard drive, so I’m sharing a bunch of chaff for a tool called “Z3”, which has all sorts of uses in software research. First ...
