The biggest event of this week is definitely Amazon re:Invent and so far the most exciting announcement is the Amazon Lambda cold start improvement by 90%. This was the major showstopper for many services, and now no more. Another item worth noting is the start of the Advent of Code - everyday programming tasks for the whole of December.
Synthesized.io and Testcontainers integration
We all love integration tests, and Testcontainers is an excellent tool to set up them. However, in order to have valuable tests we want to run them against the close-to-production data. This is where a Synthesized solution comes in handy. And the good news you can now use both products combined. Check out more details in the video.
Improving Kafka client performance by 40% by cleaning up unused Topic Metadata By LinkedIn 👷♂️
You might wonder how empty topics can slow down a Kafka Cluster, but they actually do: metadata is still stored in ZooKeeper, the partitions polls it etc. At scale it can be significant. LinkedIn Engineering Team came up with a TopicGC service, which will monitor for empty topics and drop them. Get more details inside.
Preparing for the Systems Design Interview 🍼
System Design interview is a common step in the hiring process in many companies. Gergely Orosz made a cool write-up half a year ago on the books, courses, prep materials and mock interview resources which can help you to prepare. I can personally help with them too :)

Create Your Distributed Database on Kubernetes with Existing Monolithic Databases 👷♂️
Kubernetes gained huge success in container orchestration. But using databases in with it is still not a completely solved problem. The article describes how you can upgrade your database to be distributed and pair it with your K8s workloads through Apache ShardingSphere that we have already spoke(in #34) before.
Discovering performance issues at Netflix 🤟
Netflix managed to triple it's RPS per VM Node. However in order to do that, they had to go way down to the JDK implementation and patch the two problems: "False Sharing" and immediately after that "True Sharing", which happened for super-class cache. A complex, but fascinating read about JVM optimization. If it was a bit hard to understand, there is an explanatory article here.

Short ML Course on GANs 🤟
Machine Learning is everywhere. I am sharing a short course from Google, which explains how GAN - Generative adversarial networks - works. Check out the relations between a generator, discriminator and loss functions there!
In search of a robust model
The only constant in IT we have - is that everything changes. Technologies come and go, architecture approaches transform, the way we work change as well. Humans need some basis to rely on; Uwe suggests that a robust change model can save our psyche. He says, let's embrace the constant change and have a process of adopting new things. The full thought journey below.
