Use Proxy for Git/GitHub

Generally, the Git proxy configuration depends on the Git Server Protocol you use. And there're two common protocols: SSH and HTTP/HTTPS. Both require a proxy setup already. In the following, I assume a SOCKS5 proxy set up on localhost:1080. But it can also be a HTTP proxy. I'll talk about how to set up a SOCKS5 proxy later.

SSH Protocol

When you do git clone ssh://[user@]server/project.git or git clone [user@]server:project.git, you're using the SSH protocol. You need to configurate your SSH client to use a proxy. Add the following to your SSH config file, say ~/.ssh/config:

ProxyCommand nc -x localhost:1080 %h %p

GSBASE and FSBASE

When you're running out of registers while writing a JIT, you might resort to more unconventional methods for memory access. You might choose to resort to segment registers if you need a fixed register for memory offsets.

Instructions such as:

lea    rax,gs:[rcx+rdx*8]
mov    rax,gs:[rcx+rdx*8]

would then be available for your use.

浏览器内核/渲染引擎/排版引擎/解释引擎/Rendering Engine

渲染引擎主要是负责HTML, CSS以及其他一些东西的渲染.
有时, 浏览器内核, 除了渲染引擎, 也悄悄包含了javascript引擎. 如: WebKit, 它由渲染引擎WebCore和Javascript引擎JSCore组成.
IE: Trident
Safari: WebKit(KHTML分支) -> WebKit2
Chrome/Chromium: Chromium引擎(WebKit分支) -> Blink引擎(基于WebKit2)
Opera: Elektra -> Presto -> Chromium引擎 -> Blink引擎

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
