April 13, 2024 I recently received an issue report that ijq was performing slowly. The issue claimed that, when used on a large (16 MB) JSON file, ijq was “too slow to be usable”. I downloaded the test file which was (helpfully) provided in the issue and tried it myself. Even using the most charitable definition, I ...

Instead, its given me motivation to finally write up my feelings on the issue. I've been a systems programmer for a long-time and at this point, and I'...

Back in 2019, we started thinking about how allow Lambda customers to use container images to deploy their Lambda functions. In theory this is easy enough: a container image is an image of a filesystem, just like the zip files we already supported. The difficulty, as usual with big systems, was performance. Specific...

The wrong way to speed up your code with Numba
