Agile Tour Vietnam 2015 in HCMC

I had a chance to join this event today. It was great!

For who don’t know Agile Tour, the following is the basic information from http://at2015.agiletour.org/

“Agile Tour has been a way for enthusiasts of Agile to spread the word about Agile practices and to share their experiences, both good and bad, within their local community. These non-profit events occur every year in October and November in several cities.”

Many valuable topics were shared to the community. The topic I like best is “Software Craftsmanship” from Mr. Sandro Mancuso. “Software craftsmanship” is an approach to software development that emphasizes the coding skills of the software developers themselves (wikipedia). I would like to share with you my notes about it:

Agile is actually “a quick feedback loop”. For example, we review the user stories after 2 weeks, we will get feedback; we apply TDD, we will get feedback immediately, etc.
Scrum, a Agile framework, is one main stream of Agile’s framework had a big issue that is technical debt. This is a reason why we should apply XP Practices such as TDD, Pair Programming, Automated Test, etc,… in order to improve the quality of products.
“If you want to go fast, you need to go well”. The reason is that we maybe build the project fast at the beginning if we don’t care too much about the quality of code, structure of project, technical, etc. And then, we will be slow down later on when project is bigger. Because we did not do well before and a lot of bugs occur.
“Building the right thing right”, that means Agile is somehow the “right thing” and we should build it right. According to that statement, we have the manifesto for Software Craftsmanship that is extended from Agile manifesto:

Not only working software but also well-craft software.
Not only responding to change but also steadily adding value.
Not only individual and interaction but also community of professional.
Not only customer collaboration but also productive partnership.
Best practices ever: continuous improvements and finding a better way than the old one.

Here is some pictures were take from this event.

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent"> <div id="child"> </div> </div> And, CSS: #parent{ position: relative; overflow:hidden; } #child{ position: absolute; top: -1; right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-positi...

JSF 2 - Dynamically manipulating the component tree with system events

Let's suppose we want to modify the metadata (attributes) of elements such as render , requried , maxlength but we do not define in JSF tags. The manipulating components can be conducted in Drools files, for example. How could we do? I think that is what we need to change something of component tree during JSF life-cycle. JSF supports event handling throughout the JSF life-cycle. In this post, I use two events: postAddToView for scanning components tree and preRenderView for manipulating the meta of components before rendering to GUI. I modified my own project from previous post for this example. This is my first further JSF trying out with the project as I said before. :) We define the tags f:event below the form - a container component of the components which we want to work on. The valid values for the attribute type for f:event can be found from tag library document of JSF 2. <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" x...

BIRT - Fix the size of an image

I use a dynamic image as a logo my report in pdf. At the beginning, I use table to align the logo in left or right. I meet a problem with some images with a large width or height. My customer requires that the logo should be displayed in original size. These following steps solves my problem: 1. Use Grid instead of Table 2. Set Grid "Height" is 100% and "Width" is blank 3. Set "Fit to container" for images are "true". Download the the template here .

Junit - Test fails on French or German string assertion

In my previous post about building a regex to check a text without special characters but allow German and French . I met a problem that the unit test works fine on my machine using Eclipse, but it was fail when running on Jenkins' build job. Here is my test: @Test public void shouldAllowFrenchAndGermanCharacters(){ String source = "ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ"; assertFalse(SpecialCharactersUtils.isExistSpecialCharater(source)); } Production code: public static boolean isExistNotAllowedCharacters(String source){ Pattern regex = Pattern.compile("^[a-zA-Z_0-9_ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ]*$"); Matcher matcher = regex.matcher(source); return !matcher.matches(); } The result likes the following: Failed tests: SpecialCharactersUtilsTest.shouldAllowFrenchAndGermanCharacters:32 null A guy from stackoverflow.com says: "This is probably due to the default encoding used for your Java source files. The ö in the string literal in the J...
