缩微版的ruby历险记

..小场景出自“咋的就那么呛红宝石指南”

DWEMTHY'S ARRAY

窦文太的阵
吓死人嘞

简直要雷电烫我头发

它是个动脑筋的测验题
把脑袋撞出大血包

一边玩一边感到悲喜交加

你仍是只兔子, 到目前为止还是!

在这个游戏里，你是只垂死的兔子。龙也得去死。Dwemthy's Array无底的黑暗深渊。

class Dragon < Creature
life 1340 # tough scales
strength 451 # bristling veins
charisma 1020 # toothy smile
weapon 939 # fire breath
end

class 龙 < 生物
生命 1340 # 老硬的鳞片
力量 451 # 竖立着板筋
魔力 1020 # 呲牙坏笑
武器 939 # 吹气吐火
end

马上还有更多代码

拜托, 甭提谁是窦文太。显然他是个幕后操纵者从不泄露行踪和真实身份。他祖上有豪门血统。他掌握活的冒烟吃人魔兽。
各处来的马整天闻他添他。最重要的是他知晓肉体上的快乐。然后我们来思考这个...

这个是他的兵阵。

Title: Vice President Engineering

ShangBy Inc. is a US venture backed early stage company founded in November, 2006 by
Steve Bell. The Company is headquartered in Austin, TX, focused on the US market, with
the bulk of its operations in Shanghai, China. As ShangBy expands into other cities across
Asia, the Company plans to keep Shanghai as the operations center.

Basically, think "YouTube meets "QVC / eBay" (home shopping). ShangBy is creating a
new shopping category and platform - where people come to be entertained and participate
in the markets of the world. Specifically, the Company streams real time video to shoppers
in the US. A single individual or group of US located customer(s) shop as if they are “live”
in the store in Shanghai. The retailers and ShangBy hosts do the translation and buy on
behalf of ShangBy's US customer. Everyone else watching on TV or the Internet can "pileon"
and buy at the price set by the live shopper both during and after the live events.
ShangBy takes care of all technology and operational logistics and charges transaction fees.

business plan
? Drive cost from event capital and technical delivery in range of 25+% per year
? Build team recognized for superstar talent, quality opeations and technology, and
hitting the plan

Background Desired:
? 5-10 years experience in a high energy fast paced software engineering team – where
candidate distinguished self from peers
? Strong demonstrated ability to develop websites with large user traffic, critical UI
design, and rich user interaction
? 2+ years prior direct leadership responsibility for 15+ person team
? English Fluency – oral and written
? US or US Company in China work experience required

What we offer
? Fun – ShangBy is a young and fast paced environment. We work hard together and

? Change the world – ShangBy is creating a NEW shopping category – one that
exposes millions of westerers to real people in real stores across Asia. ShangBy
believes it can provide westerners an important positive experience with the people
and cultures of Asia
? Work with Great People – ShangBy hires the brightest people available across all
functions at the company. It is the “brighness” along with the can-do, positive,
action-oriented “DNA” in ShangBy’s people that make them “Great”.
? Share in the success you create – Making ShangBy big – enabling people to really
shop the world – anytime, anywhere, anyplace – will be a team effort. The equity
compensation program at ShangBy is designed so that each person shares the
wealth we all create together.
? Multi-cultural and 24 hours per day – with operations in Austin and Shanghai –
ShangBy people can work with their colleagues all day and all night should they
like (kind of kidding – but candidates need to be ready for un-orthodox work
schedules)

Edge Rails 新特性之 Easy Memoization ... 1 reply

gemstone — Wed, 16 Jul 2008 09:55:33 +0800

*要cache实例变量，以前做法：

class Person < ActiveRecord::Base
def social_security
@social_security ||= decrypt_social_security
end
end

*Edge Rails ：

class Person < ActiveRecord::Base

# Memoize the result of the social_security method after
# its first evaluation
memorize :social_security

def social_security
decrypt_social_security_for
end
end

原理：
这两种方式本质上是一样的，Edge只不过在幕后通过alias methods 做了类似于@social_security ||= decrypt_social_security的操作
