Garbage Collection: Generational? Incremental? Both!
The third Language Summit talk was brought by Mark Shannon, who is the author of the incremental garbage collector implementation shipped in Python 3.14 that was reverted back to the generational garbage collector from Python 3.13 after reports of “significant memory pressure” in production environments. The original goal of the new incremental garbage collector was to reduce maximum pause times by an order of magnitude for larger heaps.

Functional ultrasound imaging from scratch
Functional ultrasound imaging (fUSI) is a brain imaging modality that is just starting to be demonstrated in human studies. I’m sure many will be familiar with structural ultrasound imaging, which forms static images using ultrasound, as in a sonogram1. Functional ultrasound instead captures movies of brain tissue very rapidly, tracking subtle changes caused by the blood flow that follows neural activity.
