一个数学家的自白(ZT)
    摘要： 一个数学家的自白(ZT) 假如真的能把我的雕像塑在伦敦纪念碑上的话，我是希望这座碑高耸入云，以至人们见不到雕像呢，还是希望纪念碑矮得可以使人们对雕像一目了然呢？我会选择前一种，而斯诺博士可能会选择后一种。     （全文共62547字）——点击此处阅读全文

揭开人类思维之谜 三个特定场景最易引发灵感
    摘要：人的创造性是什么？它来自何处？过去25年来，一大批心理学家、社会学家、人类学家和神经学家对人的创造性思维问题做了大量深入的研究工作。但关于这一神秘精神过程的任何观点，都不如美国华盛顿大学的心理学者R.基思·索耶的观点新颖。据《时代》周刊报道，索耶写了一本解释人的创造性的新书《人类创新的科学》。该书的普及版将于2007年面世。 在人类的创造性上，索耶教授在他的新书提供一些增强人们创造性的方法，这些方法不仅在艺术、科学和商务领域是可行的，一般日常生活中也可以使用。     （全文共3642字）——点击此处阅读全文

Peter F. Drucker-------- MANAGING YOURSELF
    摘要：We live in an age of unprecedented opportunity: If you've got ambition and smarts, you can rise to the top of your chosen profession, regardless of where you started out. But with opportunity comes responsibility. Companies today aren't manag? ing their employees' careers; knowledge workers must, effectively, be their own chief executive officers. It's up to you to carve out your place, to know when to change course, and to keep yourself engaged and productive during a work life that may     （全文共47370字）——点击此处阅读全文

帝国主义春苗——在美国作医生的经历 （转贴）
    摘要：行医指南是医学标准化。标准化可以使国家法制，市场规范透明，工业自动化，然而也可以使医生赤脚化，因为行医一旦有准则可寻，也就有了靠背书吃饭的天地。标准化的作用如此之大，一个病例一旦有了诊断，好比产品送上了流水线，人和机器的作用区别不是很大，仿佛人人都有雷锋精神甘当螺丝钉。证据行医原则对行医方式的影响在Ｄ先生病例中处处可见。Ｒ医生处处是指南挥手我前进，而Ｔ医生则大概根本没想过他是在一条错误的流水线上操作。换句话，如果Ｄ先生持续高热，最终导致诉讼，Ｔ医生是肯定没事，因为传染科的责任是帮着选择抗菌素，而Ｄ先生病例中抗菌素的选择无可挑剔，虽然药不对症反而添病。Ｒ医生如果不坚持ＰＡＮ诊断大约也不会有事，因为她既有病理诊断为凭，又有指南可循。但停了药，如果高热不退或是Ｄ先生病情恶化，从而导致诉讼，要捍卫停药人的职业道德和专业能力，不定因素就很多，因为无据可凭，谁也没有把握。     （全文共6687字）——点击此处阅读全文

Comparison of different SQL implementations

Comparison of different SQL implementations

The goal of this page — which is a work in progress — is to gather information relevant for people who are porting SQL from one product to another and/or are interested in possibilities and limits of 'cross-product' SQL.

The following tables compare how different DBMS products handle various SQL (and related) features. If possible, the tables also state how the implementations should do things, according to the SQL standard.

I will only write about subjects that I've worked with personally, or subjects which I anticipate to find use for in the near future. Subjects on which there are no significant implementation variances are not covered. Beta-versions of software are not examined. Furthermore, I will not mention all the cases of MySQL not supporting standard SQL features.

I'm sorry about the colors. They are a result of wanting to mark each DBMS differently and at the same time wanting to be relatively nice to printers.

Standard	The latest official version of SQL is SQL:2003. I don't have access to the official ISO standard text, but Whitemarsh Information Systems Corporation provides a rather final draft as a zip-archive, containing several files. Most important to this page is the file 5WD-02-Foundation-2003-09.pdf. SQL:2003 is very new, and the only book currently covering the subject is in German which I was never any good at. Therefore, I also use the following book as reference: Jim Melton and Alan Simon: SQL:1999—Understanding Relational Language Components (ISBN 1-55860-456-1).
PostgreSQL	PostgreSQL 8.0.0 on Fedora Core Linux. Documentation
DB2	DB2 Universal Database Personal Edition v. 8.1FP7 (AKA v. 8.2) on Fedora Core Linux. Note that there are differences between various DB2 UDB flavors; this page is about DB2 for "LUW" (Linux/Unix/Windows). Documentation (takes a while to render properly)
MS SQL Server	MS SQL Server 2000 SP3a on Windows Server 2003. Microsoft's SQL implementation is sometimes named Transact-SQL. In this document, I'll generally write MSSQL as a short-hand for Microsoft's SQL Server product. Documentation (takes a while to render properly)
MySQL	MySQL Database Server 4.1.9 on Fedora Core Linux (i.e. MySQL AB's "classic" DBMS product—not MaxDB). Documentation
Oracle	Oracle Database 10g Release 1 Standard Edition on Fedora Core release 1 (Linux). The tables should hold for version 9i, as well (Oracle 10g contains remarkably few improvements/changes in Oracle's SQL standard compliance). Documentation (requires OTN-membership)

《学哲学 用哲学》：李瑞环语录 http://news3.xinhuanet.com/book/2005-11/07/content_3745488.htm

一个普通的木匠，是怎样一步步走到党和国家最高领导层？——在老百姓眼里， 这充满了传奇色彩。从李瑞环已经公开的简历来看，他1934年出生于天津宝坻的农民家庭，年少时学了一手木匠功夫，此后背着木匠工具只身闯荡北京城，18 岁时成为第三建筑公司工人。24岁时已经是人民大会堂建筑工地上的突击队队长。 不过在新书中，李瑞环并没有对人生经历作描述，而是围绕哲学讲述他的心得。 新书收录了李瑞环1981年以来在天津和中央工作期间的有关文章和讲话，记录了李瑞环学习和运用马克思主义哲学的体会，其中不乏对当代中国现实的思索和感 悟。新华网读书频道特地选载该书上册内容《处处都有辩证法》，以飨读者！
