I'm also interested in what they did to kube-scheduler. They say that the scheduler is a big source of latency because of its "one-pod-at-a-time" behaviour, and that this doesn't work for "ultra-scale" or big ML workloads. But then they say,

"However, we achieved consistently a high throughput of 500 pods/second even at the 100K node scale by carefully tailoring scheduler plugins based on the workload and optimizing node filtering/scoring parameters."

How does this work??? What did they do??? Again, frustratingly light on details.

Start with the Jar: How to understand your capacity via Turtle’s Pace [Shared]

Optimism is dangerous, especially when it comes to planning our goals. If we underestimate the effort of an endeavor, we set ourselves up for failure. When we fail to meet our expectations, we can succumb to cynicism.
We must learn how much we can process to avoid the hope trap.

Imagine you have thousands of marbles to carry on a plane, and airport security released a new regulation that limits an individual to one jarful. If you don’t know the jar's capacity, you won’t know how many marbles you can bring and could risk losing your precious orbs!

Let's talk about how to choose the right scheduler? What is the workload constraint? Is scheduling a bottleneck? Is the system mostly idle? What are the latency vs. throughput requirements? What is the hardware topology?

These all sound like questions that ~nobody is asking about the Kubernetes scheduler.

I dunno if anybody besides me needs this, but I just published a simple Google Apps script to keep events synced across all of my different calendars.

(I'm aware that you can share calendars, but you can't---as far as I know---have events on a calendar that is shared with you show up when _other_ people are trying to schedule something with you. This is exactly what Cal.com et al try to solve, but I can't tell everyone at organizations X, Y, and Z to not use their normal scheduling process for the one weird contractor dude).

Anyways it's here if you want it, YMMV, standard disclaimers apply, may cause the universe to explode (which would be a massive relief, tbh).
