使用 Python 内置的 defaultdict
,我们可以很容易的定义一个树形数据结构:
def tree(): return defaultdict(tree)
就是这样!
class Graph: | |
def __init__(self): | |
self.nodes = set() | |
self.edges = defaultdict(list) | |
self.distances = {} | |
def add_node(self, value): | |
self.nodes.add(value) | |
def add_edge(self, from_node, to_node, distance): |

Hamming and Manchester Encoding example | |
Author: Joel Addison | |
Date: March 2013 | |
Functions to do (7,4) hamming encoding and decoding, including error detection | |
and correction. | |
Manchester encoding and decoding is also included, and by default will use | |
least bit ordering for the byte that is to be included in the array. |
The plan is to create a pair of executables (ngrok
and ngrokd
) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok
to connect to this ngrokd
, and vice versa.
Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com
, you'll need a record for that and for *.domain.com
.
good, 你已经有了一个自己的shadowsocks代理了,现在想要把这个代理公布出去给所有人分享。 | |
但是没有两个小时,代理就没法使用了,为什么?因为你需要额外注意以下事项(以下步骤需要比较高的linux技能) | |
本文只关注于确保shadowsocks服务还“活着”,如果你希望让其跑得更快,请参考 | |
https://github.com/clowwindy/shadowsocks/wiki/Optimizing-Shadowsocks | |
1、 shadowsocks的timeout设置 | |
超时时间越长,连接被保持得也就越长,导致并发的tcp的连接数也就越多。对于公共代理,这个值应该调整得小一些。推荐60秒。 | |
2、 检查操作系统的各种限制 | |
对于openvz的vps,特别需要检查一下 |
