別人的工作總是特別容易，自己的工作總是特別艱鉅？！
別人的成果總是特別易得，自己的辛勞似是特別多付？！

開始 ohong POS

2008-10-20T09:42:00.006+08:00

收到了 J 神平日使用的出入貨，轉貨表格。很需求上，現在要考慮的是 User Interface。

從技術層面上，現在的問題是怎連接起 GWT 和 appengine。

在使用 GWT 上，應該會使用 cypal 作為在 eclipse 上的 plugins 來新增 module 和 service。

在使用 appengine 上會使用 pydev 作為在 eclipse 上的另一個 plugins 來寫 python。

GWT 所生成的 html + js 等都試過放在 ohongpos 中跑過，並出現了，在資料上的連接應該是會使用 JSON 這技術的了。問題只是未完全掌握。

CISSP Day 1: Access Control

2008-08-18T10:46:00.003+08:00

In CISSP, Access Control consider 'Avaliability', 'Integrity' and "Confidenticiality'.

To archive these 3 area, it has "Identify", "Authentication", "Authorization" and "Accountability".

In the Authentication has 3 factors. Any 2 of 3 can be including in an authentication, it will consider as 'Storng Authentication'. They are,

1. something that the person know
2. something that the person has
3. something that specific for the person

Most of time, we uses 'Logical Access Control' to do these area. In CISSP, "Logical Access Control" is equal to "Technical Access Control".

In CISSP, identification management will consider on 6 areas. They are,

1. Directory management
2. Web access management
3. Priavcy single-sign on
4. Password management
5. Account management
6. Profile update

My CISSP Studying Plan & Progress

2008-08-15T08:49:00.005+08:00

I like to have plan and finish my target slowly. Therefore, I tried to plan my CISSP studying schedule with my progress update here.

Google gadget to show my comic?

2008-08-07T10:24:00.002+08:00

yes, this may be a good idea. I'm thinking about this.

Comic creation

2008-08-07T10:23:00.002+08:00

I have an idea to draw my comic long times ago. Just don't have any topic for drawing it.

But, i found my innovation and creation on the comic topic is coming recently. All because my dearest girl friend, Helen. I love her really much.

Develop a Google gadget about my CISSP studying progress

2008-08-07T10:17:00.001+08:00

I'm thinking about develop a Google gadget for display my road to CISSP studying progress.

CISSP preparation

2008-08-05T11:12:00.003+08:00

With my girl friend, Helen, encouragement. I decided to start my CISSP exam preparation.

Yeah... It's no guarantee on the successful of exam. But, I'll try my best arrangement and study hard on this.

Firstly, I'll selected the CISSP Certification All-in-One Exam Guide 4th.Ed as my major study reference.

Secondly, I have my plan of studying according to each CBK section size in the book as this.

Next step?!

2008-06-14T23:52:00.001+08:00

Received the ITILv3 Foundation Exam result on 12 Jun. I passed it with 88% corrected answer. I was already satisfied with this result. :)

How my next move? Move to the service life cycle module study and take the corresponding 5 module exam? Complete my current XML Master exam? Start the new CISSP and CISA exam? PRINCE? or Certified Function Point Specialist (CFPS)?

From my point of view, the level of difficulty can be sort in this order.

1. XML Master basic exam (2 stars level) - 1 month (end by Aug 08')
2. XML Master prof. exam (3 stars level) - 2 month (end by Nov 08')
3. CISSP (3 stars level) - duration 3 months (end by Feb 09')
4. PRINCE (4 stars level + training course needed) - 3-4 months

5. CISA (don't know yet) - unknown
6. CFPS (4 stars level with exam location problem) - unknown

Some other my interested areas including,
- Embedded Linux Associate
- Embedded Linux Professional

Finally, the problem is how to force myself to be hard studying. But not, fall into many different entertainment and the super high pressure work environment... @_x

ITIL 3.0

2008-06-09T23:21:00.002+08:00

Finally, I take ITIL v3 Foundation for IT Service Management (3-days course) that provided by HP Education on April. It is a very expensive course ($_$)... I paid it with my money... painful...

At the end of this course, I take the ITIL Version 3 Foundations Certification Exam. I'll have the exam result on next week. If the exam passed. I will start my student on the Lifecycle modules and need to take 5 more exam at least. (if i don't need to re-take any one of these 5 exam :P ).

Seems the ITIL v3 need many exam to be ITIL Expert. Another meaning is ... need many money to be ITIL Expert.

XML Certificates exam preparation reloaded

2008-03-29T00:18:00.003+08:00

A very suddenly workload happened in my last 2 months. It come from key men in the project team resigned; major technical feasibility decision must be confirm; Project schedule; and, office humanly problems.

Many different issues / problems happened in these 2 months. Every single issue was trouble enough to make me exhausted. With these very good reasons, my XML certification exam preparation was suspended. :)

After the technical feasibility study has good enough insight to proved that we are in the right track; partial projects off loaded to a fresh middle management; and trying to forget the office humanly problems... I think this is a good time to come back to my XML Certification exam preparation now. So, my preparation work is reloaded. ha!

Since, I'm planning to take an ITIL participators course at the end of April. I'll try to have a very active schedule to study and take exam of IBM Test 142 XML 1.1 and Related Technologies.

Good luck for me!

第一次到香港花卉展

2008-03-22T13:13:00.003+08:00

在花卉展內看到很多很美的花，有些更是從未見過的。最深刻是當中的多色蝴蝶蘭和鮮艷得不能言喻的鬱金香。我更是第一次拿著新買的D60拍下了很多花的照片，雖然拍照水準很一般，但花的美艷郤補救了我技巧的不足。

XML Master or XML Certification?!

2008-01-20T12:08:00.000+08:00

Over 2 weeks self-study for the XML Master (basic) certification. The basic syllabus contents were reviewed.

When I trying to search a test kit, I found some comments about this XML Master certification and comparison with IBM 142 XML and related technology examination in an XML certification discussion forum.

And, I have these considerations for me to take the IBM one.
1. from a laymen point of view, IBM is more famous than XML Technology Certification Committee
2. I need to only take one exam to get the IBM XML certification, but 2 in XML Master certification, seems time and cost effective
3. there has more exam kit about IBM XML cert 142 exam can be search from internet

Although, the syllabus of IBM XML certification covered more than XML Master (basic) + XML Master (prof) certs. This implied that the exam can be assumed be more difficult to pass?! And, I need longer time to prepare.

I'm changing my mind to take the IBM XML and Related technology exam 142 now. :)

XML Master cert study notes on the morning of 16 Jan 08

2008-01-16T10:12:00.000+08:00

New founding on this morning. I found the reading of Tech Yourself XML in 21 Days 3rd Edition for the XML Master (basic) Certification examination should already ended. As, I can't found any contents about XPath in the Day 14 chapter. So, the Day 14 chapter will be ignore for the exam too.

Next,I should going to clarify the areas that still mess for me tonight. ^^

XML Master cert study notes on the morning of 15 Jan 08

2008-01-16T09:56:00.000+08:00

Day 14 should be the last chapter that in syllabus for the exam. And, this chapter seems not necessary to be read completely.

According to the syllabus from XML Master certification official site, it is only the part about XLink is required in the XML Master Basic certification exam. As exam oriented, I'll going to skip other contents in this chapter.

After finished this chapter, I'm planning to clarify several area understanding. e.g.,

1. Using Axes
- definition of ancestor
- definition of descendant
- following and following-sibling
- preceding and preceding-sibling

2. the ID define and uses in an XML Schema with XSL Transform

And, thinking ...

XML Master cert study notes on 13 Jan 08

2008-01-15T09:20:00.000+08:00

Started the Day 9 contents this morning, and read once the chapter contents before fall into sleep...

To be truly understanding the contents in this chapter, you may need to have an XML transforming program for helping you to practice the XSL Transform element usage. e.g.,

xsl:apply-templates
xsl:template
xsl:value-of
xsl:choose
xsl:copy
xsl:for-each
xsl:when
xsl:if
xsl:otherwise

The chapter recommended an open source tool called, saxon [URL]. It is easy to uses, but I prefer to uses the Xalan from Apache XML [URL]. It because the Xalan is high frequency used XML transforming library for me.

I prepared a sample that with an XML file with internal DTD and a XSL file to test the ID selection in template. It seems work fine as expected.

However, the ID selection became work abnormal after I changed to uses external Schema with XML file.

Other the other hands, I seems missing out part of meaning of ancestor, descendant, following, preceding ... etc. when I reading the part about using axes. Specially about the different between following and following -sibling; and preceding and preceding-sibling. Need to clarify it.

XML Master Cert study notes at night on 12 Jan 08

2008-01-13T01:42:00.000+08:00

Before starting the Day 9 contents study. I read this web tutorial [URL] from W3Schools.

The web contents give me the very basic understanding the usage of XSLT.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XML/Transform" >.
...
</xsl:stylesheet>

<?xml versino="1.0" encoding="utf-8"?>
<?xsl-stylesheet type="text/xsl" href="yourstylesheet.xsl"?>
<document>
...
</document>

And then, I check the XML Master Basic Examination Guide from the XML Master official site again. I would suggest to skip the Day 10 contents, if you are exam oriented. And, my scope and reference mapping excel was updated too. [reference URL]

For the moment, I have different questions inside my head now @_@! e.g.,
- what's the different between <xsl:stylesheet ... /> and <xsl:transform ... />
- which element is the frequency used xsl element
- seems I can't clearly depicts the transformation processing.

Anyway, let's leave it on tomorrow! Good night!

XML Master cert study notes on 12 Jan 08

2008-01-12T14:56:00.000+08:00

Reviewed my studying on the last 3 days; and finished the Day 8 contents.

In the Day 8 contents, I had a feeling that it's completely a CSS tutorial. But, I still read it all. And, I got truly understanding the CSS syntax.

CSS is not some kind of XML syntax, and come with it's special kind of syntax to define it style class and style selector id that define inside a '{' and '}' with separator ':' and ';'.

I don't know how much will be including in exam. With refer to the XML Master cert scope, it should be out of syllabus. Anyway, it is not a bad idea to learn more and clear of anything in our life. ^_^

If you just want to focus on the XML Master (Basic) exam syllabus. I would suggest you to skip this Day 8 and jump to Day 9.

With the same concept of focus on the XML Master (Basic) exam syllabus, I'll only read Day 9, Day 10 and Day 14 in the coming days.

p.s.: if you are interested to download my XML Master (Basic) exam scope and reference mapping in excel file format, please feel free to visit the study group that i created for people whom are willing to take the XML Master exam. [URL]

XML Master cert study notes during 9 - 11 Jan 08

2008-01-12T14:35:00.000+08:00

Finished Day 7 studying and the Part I is completed.

Day 7 contents included more details on the XML Schema syntax.

It is including,

- using different facets with the restrictions
- define anonymous type
- create comments with <xsd:annotation .../>, <xsd:documentation .../> and <xsd:appInfo ... />
- declaring empty element and mixed-content elements
- declaring element group, attribute group and all group
- declaring choices that with the same usage as the element define in DTD <!ELEMENT document (chinesename | englishname) >
- using namespaces in schemas

As the end of this chapter reminded, contents in Day 7 only part of the complete XML Schema and more about the XML Schema inherits is not included. This caused me to thinking about what is the exactly scope of the XML Master (Basic) schema. And, I check the scope from XML Master official web site to prepare this excel.

XML Master (Basic) Cert scope and reference information mapping

In this chapter, I feel better understand the using namespaces in schemas. Specially clarified the meaning and different between qualified / unqalified local element and attributes. e.g.,

Case I:
<?xml version="1.0" encoding="utf-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamesapce="http://chanapps"
attributeFormDefault="qualified" elementFormDefault="qualified">
...
</xsd:scheme>

Case II:
<?xml version="1.0" encoding="utf-8" ?>
<xsd:schema targetNamespace="http://chanapps" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
attributeFormDefault="unqulified" elementFormDefault="unqualified">
...
</xsd:schema>

Case III:
<?xml version="1.0" encoding="utf-8" ?>
<xsd:schema targetNamespace="http://chanapps" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
attributeFormDefault="unqualified" elementFormDefault="qualified">
...
</xsd:schema>

Case IV:
<?xml version="1.0" encoding="utf-8" ?>
<xsd:schema targetNamespace="http://chanapps" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
attributeFormDefault="qualified" elementFormDefault="unqualified">
...
</xsd:schema>

XML Master exam study notes on 8 Jan 08

2008-01-09T09:28:00.000+08:00

Finished Day 6 contents.

This chapter depicts the basic of XML Schema (.xsd file).

To define an XML Schema, we need to have the basic declaration as this,

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
...
</xsd:schema>

The contents of <xsd:schema/> is the actual xml document definition.

The most basically, we can

- using <xsd:element name="document" ... /> to define an element.
- using <xsd:attribute name="publishing" ... /> to define an attribute.

Every element can be further define as a complex type, simple type like this.

Define element with simple type:
<xsd:element name="name" type="xsd:string" />

Define element with customised complex type:
<xsd:element name="document" type="documentType />
<xsd:complexType name="documentType">
<xsd:sequence>
<xsd:element name="title" type="xsd:string" />
<xsd:element name="author" type="xsd:string" />
<xsd:element name="publishing" type="xsd:date" />
</xsd:sequence>
</xsd:complexType>

XML Master exam study notes on 7 Jan 08

2008-01-07T09:43:00.000+08:00

This is the declaration of an xml document

<?xml version="1.0" encoding="utf-8"?>

An optional attribute "standalone" can be uses to identify whether an xml document need to reference an external reference.

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

DTD standard for Document Type Definition, it is a kind of define to verify whether an xml document is a valid xml document.

We can use a <!DOCTYPE> element to create DTD, like this

<!DOCTYPE demo [
<!ELEMENT demo (date, location)>
<!ELEMENT date (#PCDATA)>
<!ELEMENT location (#PCDATA)>
<!ENTITY kt "Kown Tong">
<!ENTITY klncity "Kowloon City">
]>

Inside the Day 5 study, it seems not much related to the namespace handling in DTD. And, the NTATION, NTOKEN, MNTOKEN ... etc. need to have more explainations.

4 Jan 2008

For the moment, I read the Day 1, 2, 3 and 4 of the Tech Yourself XML in 21 Days 3rd Edition.

It is not difficult for a developer to understanding, but only about the handling Namespace in DTDs.

I'll start the Day 5 studying tonight. It is about handling attributes and entities.

XML Master Certification group created

2008-01-01T18:52:00.000+08:00

Since, the extremely busy work... I'm being forced to hold my studying path over 3 months.

At the end of 2007, I resumed my study again in my 9 days vacation. ^^

I think there should a lots of people whom like as me, but want to share our own study materials with someone need it. Therefore i created a group in Google group for everyone whom are interesting to take the XML Master Certification examination, can share their experience and study information together.

Software Design

2007-09-28T12:20:00.001+08:00

It is some kind of difficult actually...

You need to know 'how', 'when', 'where', 'which' and 'why' the design pattern should be uses.

And, you also need to understanding and leverage the development and requirement.

Whether the software capable to be uses? ease-to-use?

People can be very easy to channellege your design and your software from a very general point of view.

However, you have hounsands or even a million concerns on one decision. You need to balance every concerns. The interesting point is ... different people has different priority on each concern. That's means you will never get everyone completely satisfy on the software design.

From a more abstract understanding on this situration. You can not difficutl to understanding and found that... Software Design just a very typical case as like as every think in our life. Is that means our life just part of software design? ops...

XML Master Exam preparation (week 5)

2007-09-24T13:53:00.000+08:00

The last week, I tried to read the XSLT and XPATH W3C specifications. However, it's really difficult to read.

I think it's really difficult and not appropriated to ask study to learn something from the abstract concept like meta structure.

I was trying to find any ease-to-read reference book to study this part.

XML Master Exam preparation (week 3 - week4)

2007-09-23T23:12:00.000+08:00

Fix AppFuse generated application that couldn't connect HSQLDB database

2007-05-13T01:34:00.001+08:00

Step 1: Enable the hibernate show sql features. This for tracing which SQL have problem to execute. If the 1st one has problem, we can going on.

Step 2: Since, the original AppFuse 1.9.x is not well prepare for the HSQLDB. We need to prepare the table creation script for the HSQLDB. i.e., hsql-create.sql, in the metadata folder of the project generated by the AppFuse.

Step 3: Using command "ant db-prepare" or click it the "db-prepare" to execute it in the Ant view of the Eclipse.

Step 4: Using command "ant compile" or click the "compile" in the Ant view of Eclipse.

Step 5: Using command "and deploy-war" or click the "deploy-war" in the Ant view of Eclipse.

It's obviously that there has another process occupied the port 8080 or 8009. I uses the command, "lsof -i | grep LISTEN" to check the PID of the process that using the port.

imachome:/usr/local/apache-tomcat-5.5.20/logs chanapps$ lsof -i | grep LISTEN
java 298 chanapps 11u IPv6 0x2e2e3a0 0t0 TCP *:http-alt (LISTEN)
java 298 chanapps 18u IPv6 0x2e2ec50 0t0 TCP *:8009 (LISTEN)

And then, kill the process with "kill -9 298" command. Now, the tomcat recover!

Eclipse plugins for HSQLDB

2007-05-08T23:55:00.001+08:00

When I trying to compare and select between HSQLDB and Apache Derby as the database for my mini application.

I found the Apache Derby has an interesting Eclipse Plugins can help to start and stop the Derby easily.

It caused me going to check any similiar plugins for HSQLDB. Finally, i found a project in source forge web site. I'm exciting and start to try it. However, it disappointed me that the plugins seems couldn't be uses directly extract to the eclipse plugins directory.

I had to agree that i like HSQLDB much more than Derby (just feeling). So, I try to fix it and have this workable version even the official project site is not active since 2004.

This plugin is good and easy enough for development.

You can add nature of HSQLDB in your project by right click on the project and select "HSQLDB > Add Database Engine nature"

And then, start / stop the HSQLDB for your project by right click on the project like this.

If you are interesed about it, just following these procedures to install it in your Eclipse.

1. download it from here

2. cd to ECLIPSE_HOME/plugins/

3. extract the hsqldb eclipse plugins.zip contents in the directory. The "hsqldb.ui" and "hsqldb.core" directories should be extracted into the ECLIPSE_HOME/plugins/ direcotry, like this:

ECLIPSE_HOME/plugins/hsqldb.ui/
ECLIPSE_HOME/plugins/hsqldb.core/

And then, the next time you start Eclipse, everything should work.

Configure the HSQLDB server to store data in datafile

2007-04-26T00:33:00.001+08:00

After you started the HSQLDB in server mode, it stores the data in memory by default. You have necessary to amend the properties file to change the hsqldb.default_table_type value to use cached as below.

With reference to my previous article, the property file name should be, "My-db.properties".

hsqldb.default_table_type=cached

Start HSQLDB server in my eclipse project folder

2007-04-25T22:59:00.001+08:00

After successfully created my first application with AppFuse on MacOSX, I'm wonder how to make it work work with HSQLDB.

I found this wiki reference is really good as it simple but detail enough for the setup. I put this command in a file with the following contents; and then name it as "startHSQLDB.sh".

java -cp ~/dev/hsqldb/lib/hsqldb.jar org.hsqldb.Server -database.0 ./My-db -dbname.0 MyDB

Then, I change it's execution mode to 755 with following command.

> chmod 755 startHSQLDB.sh

Now, i can start it anytime when i need to have the development.

Setup environment variable for the AppFuse on MacOSX

2007-04-22T16:06:00.001+08:00

Edit the ".bash_login" file and add these environment variables before use start to use 'ant new' with Appfuse.

export CATALINA_HOME=/usr/local/apache-tomcat-5.5.20
export ANT_HOME=/Developer/Java/Ant

And then, copy the "junit.jar" file from the "lib/junit3.8.1/" folder inside the AppFuse directory to the ANT home "lib" folder.

And then, you can start to new a project with the "ant new" command. Just enter 3-4 simple information. Your application is created.

Using AppFuse in Mac OSX

2007-04-22T16:00:00.001+08:00

Software development, Java programming ... etc. are keeping evolution and growth. Inside there, it has many compartively dummy and repeadly works. Why it is comparively dummy? It is simple under a condition, that is "You have experince to use it".

I always thinks how to avoid this kinid of works. Now, i'm trying a framework + tool, Appfuse 1.9.4. It seems can help to start a java web-based application in a short time. This is some of my experince of using it on Mac OSX.

糖糖派完糖，你滿意嗎？感覺上好似係放粒方糖落你果大碗苦茶，仲話要分開粒方糖幾小塊，每隔幾個月先放落去苦茶到，會甜得持久些... 到底係咪真係有甜味真係得佢知囉。或者真係會甜到唔知講咩好...
