关注这个问题好长时间了。

自从迷上了户外活动后,装备的采购、更新也列入日程,虽然俺不是器材派。加拿大这边MEC的商品、服务、价格还是不错的,但很少减价销售,反正我看上的几件东东都从不减价,而美国的几家户外店经常有打折销售,有时网购还免邮费。每次看到REI.COM 的商品特价销售时,都心里痒痒的,多伦多这里不像温哥华的朋友们那么方便可以订货后开车过境去美国取,离多伦多最近的REI的店在底特律那边,往返要 800公里,到店里取货根本不现实。

以前我曾经在REI网上订货后邮寄到多伦多,邮费大概$30美刀,加拿大邮政局要代收custom charges ($35多加元),还要收$5的手续费,算下来,REI的折扣就没享受多少了。

而且有些商品是不能邮寄到加拿大境内的,比如始祖鸟的背包、衣服。

前几个月,猛google 了一下,发现了有几家美国公司专门提供US Shipping Address 的服务,看了网上的测评、反馈,我最后确定试试这两家的服务:

US Address:
http://www.usaddressinc.com/

CBI:
http://www.cbiusa.com/

这两家公司都是在大瀑布美国一侧,开车一个多小时就可以到。

电话与这两个公司联系,服务态度都很好,方法也简单。

我后来分几次在REI订购了背包、滑雪板、滑雪靴、衣服等物品,直接SHIPPING 到US Address Inc 的地址,随时在网上track UPS # , 看到“delivered”就可以去大瀑布那边取货了。

每次是从Lewiston 出关、进关。
这个公司就在190高速的边上,出关后5分钟就到了。
该公司不管重量每个PKG 都是手续US$5
觉得他们的服务还不错。

在美国购物后,如何进关?
我每次是上午去,下午返回,进关时如实报告物品的种类和价格,每次都很顺利,海关的工作人员简单问了下,一挥手就让我过去了。

但如果采购大件物品或价格高的物品,比如单反相机等要慎重。

EMH

有效市场假说(Efficient Market Hypothesis)又叫效率市场假说,有效市场假设。该假说认为,投资者在买卖股票时会迅速有效地利用可能的信息。所有已知的影响一种股票价格的因素都已经反映在股票的价格中,因此根据这一理论,股票的技术分析是无效的。
An investment theory that states that it is impossible to "beat the market" because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information. According to the EMH, this means that stocks always trade at their fair value on stock exchanges, making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and that the only way an investor can possibly obtain higher returns is by purchasing riskier investments.
由效率市场理论延伸发展,Fama 依市场效率性质提出弱势效率、半强势效率及强势效率,其分述如下:

弱势效率(Weak Form Efficiency)
目前股票价格已充分反应过去股票价格所提供各项情报。所以,投资人无法在运用各种方法对过去股票价格进行分析,在利用分析结果来预测未来股票价格,意即投资者无法再利用过去资讯来获得高额报酬。所以,弱势效率越高,若以过去价量为基础的技术分析来进行预测效果将会十分不准确。
One of the different degrees of efficient market hypothesis (EMH) that claims all past prices of a stock are reflected in today's stock price. Therefore, technical analysis cannot be used to predict and beat a market.

半强势效率(Semi-Strong Form Efficiency)
目前股票价格已充分反应于所有公开资讯上,所以,投资者无法利用情报分析结果来进行股票价格预测而获取高额报酬。因此,半强势效率越高,依赖公开的财务报表、经济情况及政治情势来进行基本面分析,然后再预测股票价格是徒劳无功。
A class of EMH (Efficient Market Hypothesis) that implies all public information is calculated into a stock's current share price. Meaning that neither fundamental nor technical analysis can be used to achieve superior gains.

强势效率(Strong Form Efficiency)
目前股票价格充分反应了所有已公开和未公开之所有情报。虽然情报未公开,但投资者能利用各种管道来获得资讯,所以,所谓未公开的消息,实际上是已公开的资讯且已反应于股票价格上。此种情形下,投资者也无法因拥有某些股票内幕消息而获取高额报酬。
The strongest version of market efficiency. It states all information in a market, whether public or private, is accounted for in a stock price. Not even insider information could give an investor the advantage.

Brief Portal review: JBoss, Liferay, eXo, JetSpeed 2

新浪网动态应用平台

新浪网动态应用平台是一个托管网站应用程序的大型系统平台,托管了近千个项目的程序和数据库等服务,每日总访问量达到数十亿Hits。全部系统采用分布式架构,可以通过增加服务器实现平台性能扩展,而无须修改应用程序代码。而平台通过一定程度的技术封装,使开发人员仍然象使用单台服务器一样简单。平台主要功能由5大系统和4小系统构成,5大系统为:程序运行环境(Web前端)、静态内容加速(Cache前端)、数据库集群、Memcached 集群、VFS存储系统,4小系统为:服务监控系统、文件和程序发布系统、网站内容编辑管理系统、线上测试调试系统。

全部系统都基于LAMP技术,并且大量使用了其他优秀的开源软件如:Xen、Haproxy、Heartbeat、Cfengine等。本案例的精彩演讲,将为大家提供很好的案例参考,为自己企业构建类似的平台,提供极好的参考价值。
