  Project mention: Good resource for learning websocket? | reddit.com/r/javahelp | 2021-09-14

  And you should be good, now if you want pure hardcore stuff, try reading the websocket doc of netty.io, an overpowered network framework, it’s how I’ve learned that subject and I definitely not recommend it.

  eBPF-based Networking, Security, and Observability

  

  Project mention: Container security best practices: Ultimate guide | news.ycombinator.com | 2021-10-13

• gRPC

  The Java gRPC implementation. HTTP/2 based RPC

  

  Project mention: grpc_bench: open-source, objective gRPC benchmark | reddit.com/r/grpc | 2021-04-20

  Small clarification (to my understanding, I'm not a Java Guru) on why Java got on top - those Java implementations use something called Direct Executor. It's super performant when there's no chance of a blocking operation. But if you are to do anything more than echo service, you might be in trouble. Other implementations probably don't suffer from the same constraint. The related discussion can be found in this PR.

• uvloop

  2 8,102 6.2 Cython

  Ultra fast asyncio event loop.

  

  Project mention: Concurrency in Python with FastAPI | dev.to | 2021-09-09

• Finagle

  3 8,066 9.4 Scala

  A fault tolerant, protocol-agnostic RPC system

  

  Project mention: Akka became the de-facto solution for Scala web development? | reddit.com/r/scala | 2021-09-18

  A Smart Ethernet Switch for Earth

  

  Project mention: Recently zerotier stopped working properly unless I manually set MTU | reddit.com/r/zerotier | 2021-10-13

  I see this issue - https://github.com/zerotier/ZeroTierOne/issues/975 - and a response that the default MTU is supposed to be 1432. But like the last person who responded, I'm seeing 2800 in reality.
