WR703N OpenWrt 配置流程

下载安装

访问WR703N在OpenWrt的[Wiki页][wr703n-openwrt]，然后在Flashing一节中找到下载链接：[squashfs-factory.bin][flash.bin]，下载后别忘了[比对md5][md5sum]。^[1]

进入路由器管理界面，出厂配置为http://192.168.1.1，用户名和密码均为admin，然后进入固件更新，选择下载的文件，然后更新。

ZeroRPC简介 - 轻量级分布式通信框架

概述

分布式系统的核心是分布式通信，而传统上开发一套支持上千台规模集群，可靠性非常高的分布式通信框架，需要不少的精力投入。而在多数情景下，我们（特别是时间宝贵的OP）并不是非常关注技术实现的细节，而是希望有一套成熟、轻量、可靠性高、使用方便而且易于调试的分布式通信框架，可以直接使用，从而把时间放在具体业务逻辑上。

在PyCon 2012大会上，dotcloud公司开源了一套基于ZeroMQ和MessagePack的分布式通信框架（或者说是协议+Python实现）。该框架因为基于ZeroMQ，使用方法是RPC，所以被命名为ZeroRPC。ZeroRPC的特点在其官网的介绍中一目了然[1]：

ZeroRPC is a light-weight, reliable and language-agnostic library for distributed communication between server-side processes.

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

# urandom-reads.py infile threads
# Examples:
#   time python2.6 urandom-reads.py /tmp/urandom
#   time python2.6 urandom-reads.py /dev/urandom

# R to generate a plot of the read time distribution at each level of concurrency

- 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.
