What do Etcd, Consul, and Zookeeper do?

  • Service Registration:
    • Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
  • Service Discovery:
    • Ability for client application to query the central registry to learn of service location.
  • Consistent and durable general-purpose K/V store across distributed system.
    • Some solutions support this better than others.
    • Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
  • Centralized locking can be based on this K/V store.

Netflix on Raspberry Pi (incomplete)

Note: as @clibois mentioned below, due to the DRM Netflix uses, all decoding has to be done in CPU, making it somewhat choppy.

Note 2: Even the RPi 3 suffers from these CPU limitations. There is the potentially risky option of overclocking your RPi 3, but I haven't tried this.

If you manage to get smooth playback, please contact me, or post your solution here

UPDATE: I can no longer get this method to work. I have tried using Chromium v47, and v48, and both result in Netflix error "Oops, something went wrong" / C7053-1807, for which I can find no description online. If you manage to get things up and running, please contact me!

Different Linux utility commands (e.g. top, ps, strace, lsof, netstat, ifconfig, iftop, iptraf, tcpdump, wireshark)

Start up a container (whichever Linux flavour takes your fancy):

docker run -it ubuntu /bin/bash
docker run -it centos /bin/bash
  • top: check what CPU and Memory running processes are utilising
  • ps: see what processes are running
  • strace: monitor interactions between processes
