Installing GNU Screen on OS X in Homebrew

I want to edit in one tab, run what I edit in the other. Typical multi-view stuff. I've used Terminal.app for the last few years. Lately, however, after not long enough, Terminal gets laggy when I switch between tabs.

The stutter between edit and run is annoying, an unnacceptable. One of the major reason I've chosen to work with character based UI is because it is snappy. There shouldn't be a lag while a screen of UTF-8 is rendered in a monospace font.

The lag gets progressively longer, chipping at my productivity with irritation. The only solution is to kill all my Terminals, which essentially kills my flow. Terminal.app won't remember where I was for me. I have to initialize ever tab.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

thanks 4 putting source for a noob to learn a little

简介

如今，软件通常会作为一种服务来交付，它们被称为网络应用程序，或“软件即服务”（SaaS）。“十二要素应用程序”（12-Factor App）为构建如下的SaaS应用提供了方法论：

使用标准化流程自动配置，从而使新的开发者花费最少的学习成本加入这个项目；
和操作系统之间尽可能的划清界限，在各个系统中提供最大的可移植性；
适合部署在现代的云计算平台，从而在服务器和系统管理方面节省资源；

This demonstrates that you can configure a Flask application through Flask-Script, without having to create a Flask instance or deal with circular dependencies. Note that Flask-Script's Manager accepts a factory function in place of a Flask app object.

Running:

python manage.py runserver

gives "Hello, world!" on http://localhost:5000/, while running:

python manage.py runserver -c development.cfg
