I notice this internal tranquility seems to be related to my exodus of social media. A few months away from my online addiction has left me with two fundamental conclusions. First, My relationship with social media was “selfish”, “self-centered”, and “self-righteous” in nature. Egotistical. Next, I believe I am not alone in this experience.https://krisnova.net/tech/network-instrumentation/Mon, 22 May 2023 00:00:00 +0000https://krisnova.net/tech/network-instrumentation/Recently, I have been trying to speed up GitHub. Part of improving GitHub’s performance has involved deeply understanding how the infrastructure works. Which, is no small undertaking given the amount of uncertainty on a given day. Earlier this year I started digging into inbound connection queueing using eBPF as a means of understanding latency in our stack. You can see my public work on the topic in this article: Observing and Understanding Accept Queues in Linux.https://krisnova.net/tech/linux-accept-queues/Mon, 13 Mar 2023 00:00:00 +0000https://krisnova.net/tech/linux-accept-queues/All complex systems can, and in my opinion should, be modelled and reasoned about as a collection of queues, caches, connections, and workers. In Linux, this type of abstract modeling is not only just a good idea, it reflects quite literally how the kernel is built.

Today she works as an Engineer at GitHub. Her domain specialization is applied compute and runtime performance in the enterprise. Specifically she works with the Linux kernel, distributed runtime environments such as Aurae and Kubernetes, platform infrastructure, and open-source software engineering. In 2023 she co-founded The Nivenly Foundation to serve as a governing entity for Hachyderm Decentralied Social Media and the Aurae Runtime Project.
