胡汉三
我胡汉三又回来了！
不过识别两年，技术前沿生疏了许多。看思归的文章犹如读字母天书，WPF, WCP横行，幸好没有WTF。
重回CSDN上混，我的账号居然还在。
现在的考量是把和.NET无关的东西放在我的blogspot英文博客上，这里放CSDN上遇到的问题和解决方法。是该重新收拾对.NET地了解了——“无他，但手熟尔”。

The Annoying Details
A dedicated QA has been testing one of my application during the past few days. The good news is that fortunately, I'm still a qualified developer: the program design is solid, there is no design flaw and there is no data damage under exceptional conditions. The bad part is, I didn't pay enough attention to those details that I should have paid attention to. Here is a list of things, check how many of them are in your program:
- While using strtol or _strtoi64 to convert a user input string to numeric value, it returns the largest possible value when the number overflows. So if you use that as a criteria for overflow, you will miss out the largest value itself.
- We know port 0 through 1024 are reserved for system use, is 1024 included?
- Do you know that fopen can't open files that is located under a directory whose name contains non-ASCII characters?
- inet_addr accepts ip addresses like 10.0.1, and converts it to 10.0.1.0.
- Under what condition is “C:Temp“ a valid directory name?

2G email account from MSN
从MSN Explorer新申请的@msn.com email账号已经升级成了2G。这个比GMail的好处是直接支持POP3收件。如果你没有安装MSN Explorer的话，可以从这里下载。

Indigo, Indigo, Indy all the way
Ok, This isn't new, just in case you haven't seen: Chris Anderson and Don Box “sing” about Longhorn at Christmas (the second half).
XML once was
A simple little hack
Now with XSD there is no turning back
SOAP can make it clean
Simplicity is near
At least until the working groups let query out next year
Oh, Indigo, Indigo, Indy all the way
Oh what fun it is to send a message on its way, hey
Indigo, Indigo, Indy all the way
Oh what fun it is to keep it HTTP at bay, hey!
Oh, schemas come and go
WSDL is okay
UDDDDI will not go away
Wire formats bring many standards fights
How do we ship before the day the profile gets it right
Oh, Indigo, Indigo, Indy all the way
Oh what fun it is to send a message on its way, hey
Indigo, Indigo, Indy all the way
Oh what fun it is to blow J2EE away

The 1 Gigabyte Maniac
Guess how much people are willing to pay for a GMail Account Invitation? You won't believe it. The concept of 1 Gigabyte drives people mad.

Cars in American Life
没想过“Under the Hood”还可能有别的比喻。我的想法和展波一样：Hood是前车盖，Hood下面便是汽车的引擎了。汽车是老美生活中最重要的一部分，大约和我们的自行车差不多，算不上奢侈品。尤其是在中西部，没有汽车可以说是寸步难行。所以也就有了不少和“车”或者“路”相关的谚语，除了上面的“Under the Hood”之外，还有比如“Behind the Wheel”，用来形容亲身实践的经验；Portal Server里面经常提到的“Dashboard”指的是汽车的仪表盘，用在这里再贴切不过了。

Joycode without Joy
Just read Saucer's blog. Can't agree more!
Something is just not worth it. Joy, back anytime and you will be more than welcome.

Sleepless in Seattle
4月3日 4:00AM 坐地铁赶哥伦比亚大学早上6点到华盛顿特区参观樱花节的专车。
4月3日 11：30AM 到达华盛顿特区，参观了Capital Hill、林肯纪念堂、华盛顿纪念碑... 当然主要是看樱花了(National Cherry Blossom Festival）。
4月3日 6：00PM 原车开始返回纽约，单程需要5个小时。
4月4日 12:00AM 回到新泽西家中。整理出一些照片。
4月4日 1:59 AM 美国切换回夏令时，直接跳到3:00AM。
4月4日 3：30AM从家里出发，感到ＪＦＫ机场乘坐７ＡＭ到西雅图的飞机。
４月４日10：00AM（太平洋时间）历经６个小时的航程，到达西雅图。在Ｈｏｔｅｌ见到Ｇｒａｃｅ、Ｓａｕｃｅｒ和唐一均。
前后近４０个小时没有合眼，并且最后到达西雅图，史称Ｓｌｅｅｐｌｅｓｓ ｉｎ Ｓｅａｔｔｌｅ。 ：）

格莱美
同事Malcolm前两天请假没有来公司。今天才知道，他是去参加格莱美颁奖——不是一般意义的“参加”——他的名字就赫然列在候选名单上（Malcolm Pollack, Best Engineered Album, Non-Classical ）。可惜没能最终获奖，不然真的替我们C#程序员们长脸了。 |

技术的头脑
上传了几张加州旅游的照片。
总觉得自己没有艺术的头脑，摄影在我的手上——至少是目前为止——变成了光圈、快门这些技术参数的简单组合。没有多少构图的精巧，更谈不上什么“意境”。“某某人于某年月日到此一游”，如是而已。
还记得在三藩的现代艺术博物馆看到的一幅展品：四四方方的一块花布，用某种颜色的涂料均匀的涂抹了一遍，镶上画框，在一旁署上某艺术大家的姓名，便堂而皇之的挂在展厅一隅。来往的观众们也似模似样的驻足观赏一番。不论别人怎样，我并不指望自己有一个能够欣赏这种艺术的头脑。
时常看到有人上纲上线的把软件设计提升到“艺术(Art)”的境界。搞不懂这样一门有着明确是否论断的学科如何能够跃出“科学”的轮回之外：算法A好过算法B，设计C优于设计D，是比较效率而言——时间效率和空间效率，开发效率和运行效率。而所有这些，都是有一个1或者0的明确答案。
万幸软件设计不是彻头彻尾的艺术，不然我这个技术的头脑也要不灵光了。

休假
- 圣诞前一天从洛杉矶到旧金山，正好赶上加州地震——可能是山路颠簸，并没有感觉。最后还是从电视新闻知道地震的消息。
- 回纽约的飞机上，一手拿着花了整整一个版面报道疯牛病的Wall Street Journal，一手拿着Continental Airline的Beef Hamburger午餐。很怀疑这是航空公司节约开支的手段——多数人连Hamburger的包装袋都没有打开。
