Hey! I saw this has been indexed by the search engines. It is a first draft of a post I ended up publishing on my blog at: Scaling PostgreSQL With Pgpool and PgBouncer

Thanks for stopping by!

通过本机的81号端口访问测试服务器89的我的私人apache目录(端口为11063)

使用本地转发，在本机上输入

ssh -L 81:210.32.200.89:11063 [email protected]

这时候打开浏览器,输入地址127.0.0.1:81 我同时也试验了

ssh -L 81:127.0.0.1:11063 [email protected]

ssh -L 81:localhost:11063 [email protected]

Intercepts HTTPs Traffic with Python & mitmproxy

Warning

This Gist is created in 2014, and it's highliy outdated now, according to one of mitmproxy's manjor contributor (check his comment below). Thanks for letting us know, @mhils!

Introduction

Modern applications usually make use of back-end API servers to provide their services. With a non-transparent HTTPs proxy, which intercepts the communication between clients and servers (aka the man-in-the-middle scheme), you can easily manipulate both API requests and responses.

5 entertaining things you can find with the GitHub Search API

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].

Today we're looking for:

• The hottest repositories created in the last week.
• The oldest user accounts with zero followers. (So sad.)
• Issue trends by language.
• Clojure projects defying convention.
