So that tweet was misunderstood
I'm currently experiencing the toxic hell that is a misunderstood tweet going viral. It's a property of the social media. The more they can deliberately misunderstand you, the more they can justify the toxicity of their response. Unfortunately, I had to delete it in order to stop all the toxic crud and threats of violence.The context is how politicians distort everything. It's like whenever they talk about sea level rise, it's always about some city like Miami or New Orleans that is sinking into the ocean already, even without global warming's help. Pointing this out isn't a denial of global warming, it's pointing out how we can't talk about the issue without exaggeration. Mankind's carbon emissions are indeed causing sea level to rise, but we should be talking about how this affects average cities, not dramatizing the issue with the worst cases.
The same it true of health care. It's a flawed system that needs change. But we don't discuss the people making the best of all bad choices. Instead, we cherry pick those who made the worst possible choice, and then blame the entire bad outcome on the system.

Enforcing Network Security Policies with GitOps – Part 1
“How do I enable GitOps for my network security policies?” This is a common question we hear from security teams. Getting started with Kubernetes is relatively simple, but moving production workloads to Kubernetes requires alignment from all stakeholders – developers, platform engineering, network engineering, and security.
Most security teams already have a high-level security blueprint for their data centers. The challenge is in implementing that in the context of a Kubernetes cluster and workload security. Network policy is a key element of Kubernetes security. Network policy is expressed as a YAML configuration and works very well with GitOps.
We will do a three-part blog series covering GitOps for network security policies. In part one (this part), we cover the overview and getting started with a working example tutorial. In part two, we will extend the tutorial to cover an enterprise-wide decentralized security architecture. In the final part, we will delve into policy assurance with examples.
Note that all policies in Calico Enterprise (network security policy, RBAC, threat detection, logging configuration, etc.) are enforced as YAML configuration files, and can be enforced via a GitOps practice.
By adopting GitOps, security teams benefit in the following ways:
- Take your policies Continue reading
