Looks like they rushed the release or didn't let the LLM proofread: "Öffne Apps von deinem Android-Smartphone auf deinem Latop – ohne Installation"

Such a nice Latop!

This is just sick.
totallyunknown··on Linux Network Performance Ultimate Guide
What's missing a bit here is debugging and tuning for >100 Gbps throughput. Serving HTTP at that scale often requires kTLS because the first bottleneck that appears is memory bandwidth. Tools like AMD μProf are very helpful for debugging this. eBPF-based continuous profiling is also helpful to understand exactly what's happening in the kernel and user-space. But overall, a good read!

While the article provides guidance on utilizing standard software and services to construct a basic video upload platform, it lacks deeper insights into advanced scaling techniques.
totallyunknown··on Why I Left Rust
Is there already a ChatGPT Plugin out to summarise blog posts?

tl/dr: "The key message in this text is a call for accountability following the decision to downgrade JeanHeyd Meneide from keynote speaker at RustConf due to disagreements with his blog post. The decision was perceived as disrespectful and cruel, lacking in appropriate organizational procedures. This has highlighted a larger systemic problem within the Rust organization and prompted the author's resignation. They call for a full investigation, a greater focus on accountability rather than diplomacy, protection of individuals from such unjust actions, and the implementation of safeguards to prevent similar incidents in the future."

totallyunknown··on Roku devices don't support IPv6 in 2023 and it's costing ISPs
I have reviewed the logs for our video CDN and out of 150,000 sessions, only 48 were identified to be using IPv6. These sessions were identified by the user-agent Roku/DVP-12.0 (12.0.0.xxxx-xx), indicating that the recent update to the operating system now supports IPv6.

totallyunknown··on Pingora, the proxy that connects Cloudflare to the Internet
All in memory.
totallyunknown··on Pingora, the proxy that connects Cloudflare to the Internet
We can't use sendfile since all the traffic is HTTPS. Sendfile can only be used if we can use KTLS. Internally we have some kind of cache hierarchy for video objects, these files are transferred out via Sendfile, but the performance gain here is negligible.

A single node is single socket AMD EPCY node with 32 cores, 64 or 128GB RAM, 1x NIC with 2x100 GB/s. Ja, es ist waipu.tv.

A german company building an app for watching linear TV. Netflix is actually serving 400Gbit/s per node and already have 800Gbit/s ready.

I think we can scale our setup up to 200 Gbit/s but we are too small. Total traffic is ~2 Tbit/s.

Most challenging is the missing support of QUIC/http3 and KTLS in Golang. Also 100G NIC supply chain is difficult. We use NVIDIA Connect-X 6, but it's impossible to get a version with TLS offloading.

We did the same. We've replaced nginx/lua with a cache server (for video) written in Golang - now serving up to 100 Gbit/s per node. It's more CPU and memory efficient and completely tailored to our needs. We are happy that we moved away from nginx.

totallyunknown··on Without Systemd
Nice collection of Linux distributions I'd like to avoid now.

There might be some issues with systemd, but systemd is by far much better than anything else we had before.
