When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers

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 |

While attempting to explain JavaScript's reduce
method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.
JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List
is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu
