Apple Security Update 2007-009 updated Ruby to 1.8.6 (patch level 111) and Rails 1.2.6
Posted by dongyi under Information Technology , Interesting StuffNo Comments
The latest Apple Security Update 2007-009 updated Ruby and Rails installed on Leopard to:
Ruby 1.8.6 (patch level 111)
Rails 1.2.6
ActiveSupport 1.4.4
ActiveRecord 1.15.6
ActionWebservice 1.2.6
ActionPack 1.13.6
ActionMailer 1.3.6
The default local gems repository is in /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/
So if you?ve got a separated gems repository created in /Library/Ruby/Gems/1.8, you won?t be affected by this update if you?ve already update your Rails to the latest 2.0.2.
This could be configured by setting:
GEM_HOME=/Library/Ruby/Gems/1.8
This means you should still get Rails 2.0.2 displayed when you issue the ?rails -v? command after the update.

That’s really fast: JetBrains Support - TeamCity 3.0!!!
Posted by dongyi under Business , Continuous Integration , Information Technology , Interesting StuffNo Comments
Congratulations!!!
JetBrains pushed out its powerful continuous integration and build management server, TeamCity 3.0, last week. TeamCity 3.0 continues to extend support of both Java and .NET software development teams: per-project roles, visual statistics reports, improved code quality maintenance, and much more. For a quick look, I did an evaluation of the very first EAP release of TeamCity 3.0 back in August:
TeamCity 3.0 comes with two editions: the free Professional edition, and the Enterprise edition. The edition comparison matrix is available from the following URL:
http://www.jetbrains.com/teamcity/buy/edition_comparison.html
The full feature list is available from the following URL:
http://www.jetbrains.com/teamcity/features/index.html
The Enterprise Server is priced at $1,999 per license. But if you own Prior TeamCity licenses, you will qualify for a free upgrade to the Enterprise Edition of TeamCity. A single Prior TeamCity license entities you to run a single instance of the TeamCity Enterprise Edition Server.
I requested my Enterprise Server License 10 minutes ago through the following web page:
http://www.jetbrains.com/eshop/assistance/displayAssistance.do?assistanceProduct=TeamCity
All they need is your customer ID and one of your Prior TeamCity licenses.
I received the License Certificate email sent by JetBrains Sales Support in just 2 minutes with the brand new License Key for TeamCity 3.0 Enterprise Edition.
That’s really, really, really fast!!!
Your Prior TeamCity licenses will serve as Agent Licenses. An Enterprise Server License will automatically grant you use of three bundled Build Agents. So I should get:
1 (my Prior TeamCity License) + 3 (bundled Build Agents per instance of TeamCity) = 4.
The Build Agents could be purchased separately for $299 per agent.
Indeed, TeamCity does have quite a few competitors in the Continuous Integration Servers market, both commercial and non-commercial.
One name I have to mention is ThoughtWorks’ CruiseControl. Currently it comes with so many ‘flavours’: CruiseControl.NET, CruiseControl.Enterprise (CCE), CruiseControl.rb, to name a few…
Probably they should re-consider their marketing strategy on all their ThoughtWorks Studios products. Take a quick look of the page below:
http://studios.thoughtworks.com/cruisecontrol/purchase
Yes, they are offering the Early Access release of the ‘overwhelming interested’ CruiseControl Enterprise. But where is it? I ‘registered my interest’ in CruiseControl Enterprise in early summer this year, but still haven’t heard anything interesting…
Maybe they’re just afraid of releasing those Early Access products… Because their EA products are really, really, really full of bugs. More importantly, they won’t fix bugs found in their ‘Early Access’ builds.
Try to google ‘Mingle Early Access’ or simply search for ‘mingle’ in my blog, you’ll know what I’m talking about:

新的口岸艾滋病防治管理条例已于12月1号起在首都国际机场实施。所有在国外居住超过1年的中国公民都被列入接受艾滋病检测的范围。
按照规定，被检测时，原则上都会使用全新不锈钢针头。什么叫原则上？这种事情难道还能商量？为什么只有中国公民？殊不知中国的艾滋病疫情已经远远超过很多欧美发达国家。
更搞笑的在后面，如果被检测愿意，可以选择与同行的家人，同事或同学等共用一只针头，但共用同一只针头的人数最多限制在4人。
有同学认为这样不仅降低了成本，也加快了检测的速度。
荒谬至极啊。
听说扎针抽血80元人民币一次，看来17大以后新上台的年轻同志们确实是敢打，敢干，不怕出风头。看来中国人民的智慧终究是无人能敌啊。
下次谁再敢说中国人缺乏创造力和创新精神，我一准儿跟你丫急。
看来以后旅行的常备物品里还要加上一次性注射器若干，世风日下啊，自给自足是不是能稍微踏实

Recompile JSP files for Blackboard
Posted by dongyi under Information Technology , Interesting Stuff , Playing with BlackboardNo Comments
Specification:
- IDE: All major IDEs.
- JDK: Java SDK 1.5.
- External Tools: Apache Ant (if not bundled with IDE).
- Dependent Blackboard SDK:
- Standard bb-platform.jar
- Standard bb-taglibs.jar
- bb-portal.jar (this has to be created manually)
1. How to create bb-portal.jar
bb-portal.jar is required to compile various Blackboard internal JSPs. This is not stored in the standard location:
/usr/local/blackboard/systemlib
Please use the following command to create bb-portal.jar file. Please note this file should be created after each major or minor system upgrade.
cd /usr/local/blackboard/webapps/portal/WEB-INF/classes
# ls -ltra
total 8
drwxrwxr-x 4 bbuser other 512 Aug 9 2005 blackboard
drwxrwxr-x 3 bbuser other 512 Aug 10 2005 com
drwxrwxr-x 4 bbuser other 512 Aug 10 2005 .
drwxrwxr-x 6 bbuser other 512 Aug 4 09:08 ..
# jar cvf bb-portal.jar ./blackboard/
After this, bb-portal.jar should be created:
# ls -ltra
total 3640
drwxrwxr-x 4 bbuser other 512 Aug 9 2005 blackboard
drwxrwxr-x 3 bbuser other 512 Aug 10 2005 com
drwxrwxr-x 6 bbuser other 512 Aug 4 09:08 ..
drwxrwxr-x 4 bbuser other 512 Nov 26 13:13 .
-rw-r–r– 1 root other 1850469 Nov 26 13:13 bb-portal.jar
Copy this file to your local machine.
2. Compile JSP files using NetBeans IDE (recommended)
NetBeans IDE provides built-in support to test compile all JSP files during builds. In this case, no extra configuration is needed to pre-compile JSP files for Blackboard.
Create a new ‘Web Application’ or check out the ‘BlackboardFrame’ project on SVN.
Open the ‘BlackboardFrame’ project in NetBeans IDE. All the JSP files should be stored in ‘web’ directory and can be seen under the ‘Web Pages’ section of the project.
Open ‘Project Properties’ window by right-clicking the project and choosing ‘Properties’ in the context menu. Navigate to ‘Compiling’ section, make sure the ‘Test compile all JSP files during builds’ is checked.
Build the project by right-clicking the project and choosing ‘Build’ in the context menu.
The output message from the project build process could be viewed by pressing ‘Ctrl-4’ or choosing from Window -> Output -> Output from the toolbar.
If the build is successful, the output messages should look like:
After the build, all the generated Java source files would be stored in the following location:
Project\build\generated\src\org\apache\jsp
Please copy the required Java source files to the appropriate location (please refer to the package and folder structure of the original JSP files).
Change the package name of the generated Java source files from org.apache.jsp to the appropriate ones (please refer to the folder structure of the original JSP files).
Build the project again by right-clicking the project and choosing the ‘Build’ in the context menu.
After the successful build, please copy the Java source files, class files, and JSP files to the appropriate locations on the server.
The location of final Java class files:
Project\build\web\WEB-INF\classes\path\of\package
The location of final Java source files:
Project\src\path\of\package
3. Compile JSP files using other IDEs (using Apache Ant).
Other IDEs, including Eclipse and Intellij IDEA, do not have built-in support to test compile JSP files during builds. However, we could use Apache Ant and Tomcat container to achieve this.
Please make sure the Apache Tomcat container 5.5.x is properly installed on your local machine. I will assume that Apache Tomcat 5.5.x is installed in the following location:
C:\apache-tomcat5
If your local Tomcat container is installed in a different location, please modify the following line in the Ant buildfile build.xml:
Check out the project using the instructions mentioned above. The Ant buildfile build.xml should be already in the top level of the project structure.
The dedicated target for compiling JSP files is called ‘compile-jsp’. This is an independent target and should only be called if it is necessary.
The default Java source file output location for test compile JSP files is:
Project\web\WEB-INF\src\org\apache\jsp
Run the ‘compile-jsp’ target, and the output messages should look like:
Copy the generated Java source files to the appropriate locations and change the package name of each file according to the folder structure of the original JSP files.
Rebuild the project and you should get the JSP pre-compiled.

iPhone automatically restarted while playing ‘Bleeding Love’?!
Posted by dongyi under Information Technology , Interesting StuffNo Comments
My iPhone automatically restarted just now while I was listening Leona Lewis’ Bleeding Love…
The screen just suddently went black, and the silver Apple logo appeared…
The actual restarting time seems shorter than the normal shutdown/restart (by holding the sleep button)…
It’s really weird… Anybody got any idea?
