      • Are We Watching The Internet Die? Ed Zitron warns that the proliferation of generative AI, coupled with the incentives of major tech platforms, could lead to a homogenized, centralized internet dominated by inbred AI models trained on increasingly generic, algorithm-pleasing content — a concerning future that demands skepticism and resistance from users.
      • Google has a blog up discussing their threat modeling when deploying “post-quantum” (PQC) cryptographic algorithms. “If we do not encrypt our data with a quantum-secure algorithm right now, an attacker who is able to store current communication will be able to decrypt it in as soon as a decade.”
      • Parca - Open Source infrastructure-wide continuous profiling Polar Signals just raised a round and they have an open source tool for profiling that e.g. Vercel is really happy about decreasing their infrastructure costs.

          • Bug of Week (from our Retrospectives)

          With karpenter for cost savings, we are reaching cilium API limits due to lots of pods being evicted and need to raise those limits. Pawel then managed to figure it out. NetworkPolicy Objects with CIRDs are the culprit. Without NetworkPolicy objects everything went fine. When also 500 NetworkPolicy Objects were created each with 10 random CIDRs in them, node_local identities went up to 70k, causing cilium timeouts, causing pods being stuck in ContainerCreating. Especially for single IP networks, cilium creates 31 secondary labels. Packing single IP CIDRS into slightly bigger subnets should help. We have an upstream issue for it.
