PLRelational: Query Optimization and Execution

October 3, 2017, by Mike Ash

We've been talking a lot about PLRelational lately and what you can do with it. Today I want to talk about some of its internals. In particular, I want to talk about how it optimizes and executes queries, which is one of the most interesting components of the framework.

Reactive Relational Programming with PLRelational

August 10, 2017, by Chris Campbell

While working on the next major version of VoodooPad [1], an observation was made: user interfaces are basically just bidirectional transformation functions, taking data from some source and presenting it to the user, and vice versa. It sounds so simple when boiled down...

Swapping PCI Option ROMs

April 6, 2013, by Landon Fuller

In my spare time in the Plausible Lab, I like to play with old Mac and video game hardware — it’s fun, appeals to my strong sense of nostalgia, and if I screw up, I won’t feel quite so terrible as I would if happened to destroy a piece of expensive modern hardware. Fortun...
