Probably a lukewarm take, but I think many of us in the space around systems, especially those socio-technical systems and observability have quite a good outlook with how much "less than great" things look to be coming our way.

I have not paid a ton of attention to the uproar over RTO policies, bc we are all in on distributed teams and not going back. My impression (via social media) has been that these were shadow layoffs. Last month I asked an investor why they are doing RTO. He said: "Retention, mostly. And morale."

I gave a talk recently about how source available is thriving and open source is dying. This is an example of one of the categories of problems I pointed out. Permissive licenses are *by convention* also a collaborative culture, but they are not *necessarily* so. The difference is crucial

1. LLM-generated code tries to run code from online software packages. Which is normal but 2. The packages don’t exist. Which would normally cause an error but 3. Nefarious people have made malware under the package names that LLMs make up most often. So 4. Now the LLM code points to malware.

Kubernetes The Hard Way has been updated. I've also resolved most of the open issues and pull requests as I set the stage to add support for both ARM64 and AMD64, making the project compatible with both CPU architectures while continuing to be cloud provider agnostic.
