Project mention: Case Study: ByteDance Uses eBPF to Enhance Networking Performance | news.ycombinator.com | 2025-01-29
I'd love to see a more complete picture of ByteDance's TikTok infra. They released "KubeAdmiral" (1) so I'm assuming they're using eBPF via a Kubernetes CNI. I see ByteDance listed on Cilium's github (2). They're also using KubeRay (3). It's annoying that a company I definitely do not want to work for has such an incredibly interesting infrastructure!

Project mention: I got OpenTelemetry to work. But why was it so complicated? | news.ycombinator.com | 2025-01-10You are generally correct but I've used https://github.com/openobserve/openobserve for several projects for dev-only complete OTel stack (dashboards included) and I liked it. There are better dashboards out there for sure, but for what I needed locally it did the job fantastically well. Zero complaints.
It's extremely easy to self-host, either on a dev machine, a VPS, or in any Docker-based PaaS.
