sql server 2008正式版已经推出几个月了，明年也要出两本sql 2008的书，不能再偷懒继续用2005了。前几天下载了10.0.144版本的安装文件，狠狠心，把X61上的SQL 2005删除，全新装2008，结果鼓捣了两天，还是装不上，最后X61登录Windows都不行了。没办法，只能在新买的苹果机上做了，苹果机双系统启动，安装的是XP sp3，还算顺利。后来得知这个10.0.144版本的SQL Server不是正式版，又找到10.0.166的正式版，再战战兢兢的卸掉之前的pre-release版本，重新安装正式版，结果又报错说，之前的VS版本不合适，找到所有的Visual Studio，删除，再安

X61笔记本(xp sp2)安装了IBM的指纹识别程序，开机比较方便，拿手指抹一下即可登陆windows。因为要装SQL Server 2008，使用ms的软件把.net framework全部清除，结果，重启后发现指纹识别程序出错了，系统启动后无法进入windows，且无法扫描指纹，提示vrlogon.dll损坏，请重启计算机。重启后依然如故。经过google，找到解决方案。解决步骤如下：1、该问题出现后，系统无法进入正常模式，也无法进入安全模式，所以很多网上提供的资料压根无法使用（修改注册表等）。但可以进入系统控制台（老玩家们称之为dos模式，虽然和622完全不是一回事）。

It's also important to note that with C applications, main() isn't really the first function to be executed. Functions that get executed before main() include __libc_start_main(), _start(), and __libc_csu_init().-----Self-Service Linux®: Mastering the Art of Problem Determination [@more@]

今天下载了一本电子书：Pro SQL Server Disaster Recovery，其扉页上霍然写着：This book is dedicated to Ken Henderson (1967–2008)，Ken Henderson的书，我书架上放着两本：《SQL Server 2005 Practical Troubleshooting: The Database Engine》以及《The Guru's Guide to SQL Server Architecture and Internals》，光看这两个书名，就知道作者是何等人物。google一下，2008年1月27日，Ken Henderson去世。当初，还把《The Guru's Guide to SQL Server Architecture and Internals》中的序言一个一个单词打出来，当做专业英语的材料给

Bill Gates' High School Speech on The Eleven Rules of LifeSummary of the eRumor：Bill Gates spoke before a group of high school students and gave them his eleven rules of life.The Truth：This is not from Bill Gates. It's an excerpt from the book "50 Rules Kids Won't Learn in School: Real-World Antidotes to Feel-Good Education " by educator Charles Sykes. It is a list of eleven things you did not learn in school and directed at high school and college grads. A real example of the eRumor

在文中，王选院士缅怀计算机科学先驱Dijkstra的历史功绩，在技术的时空中浓缩大师的魅力、勾勒计算机科学发展的轨迹。但在缅怀的背后，更值得读者重视的，是王选老师对中国软件产业缺乏既懂管理又懂技术的“师才”的忧虑。Dijkstra被西方学术界称为“结构程序设计之父”和“先知先觉”（Oracle），他一生致力于把程序设计发展成一门科学。科学研究的帅才最重要的素质是洞察力（Vision和Insight），能够发现有前景的新领域或在新领域内发现和解决最关键的问题。下面仅举几例说明Dijkstra的洞察力。[@more@]解决编译系统中的关键问题FORTRAN

Shared memory allows an application to allocate a chunk of memory which can be viewed by other processes. Oracle uses shared memory to create the System Global Area (SGA) which all Oracle processes must be able to access.Semaphores act as flags for shared memory. Semaphores are either set on or off. When an Oracle process accesses the SGA (in shared memory) it will check for a semaphore for that portion of memory. If it finds a semaphore set on for that portion of memory that process will sleep
