如何學習 Meteor.js (第一階段)

Meteor 是一個 full-stack 的開發框架 (或者該說是平台)，它可以利用一種語言 (JavaScript) 來輕鬆完成前後端的開發。是目前前景看好的選擇。

本階段的目標是：

• 了解 Meteor 是什麼樣的平台，基本架構，可以做到什麼樣的事情 (2.5 hr)
• 能夠自己獨立完成一個 Meteor 的 ToDo App (不斷的練習一樣的 App，直到完全熟悉，+10 hr)

這階段大約花 10-20 hr，可以利用一個週末的兩天時間，或是一個禮拜的晚上來完成。

Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
