Retrospective with Sailboat

Have you ever got bored with the Retrospective meeting? I have, sometime. Most of the times, this meeting just goes traditionally by answering three questions: "What good things have we done? What bad things have we done? And, what actions should we improve?" Ever and ever again! My team found a way to make it a little bit more exciting. The idea is that each member - not only our Scrum Master - will become a host. If a meeting is hosted by a memeber, the next meeting will be hold by another one.

Yeah, I used "Sailboat" pattern in my turn. So, I just want to share with you guys how it was.

I started the meeting by telling a short story that I hoped everyone in my team could recall the meaning behind of Retrospective meetings:

There is a group of people trying pick up trash in a park. At the first look, the park seem not to have a lot of trash because they are spread out all over the place. However, these people continuously found trash when they started. They kept picking them up until the whole park is clean.

What exactly I did mean from this story is "just keep improving". In my opition, Retrospective is the time for us to look back what "trash" are found and try to eliminate them continuously.

Next, I drew a picture about sailing boat as a metaphor for the team. (The following is my own painting; it took me nearly one hour to complete. Haha!)

All parts of this picture are numberd from 1 to 5 with my explaination below:

[1]. Sailing boat: the team

[5]. Happy island: Sprint goal (or team's goal in general)

[2]. Wind: motivator - what moves the boat forward

[3]. Anchor: impediment - what slows the boat down

[4]. Rock: pitfall - what dangerous things are able to stop the boat

Whole members thought about it in 5 minutes, then I picked a member randomly to talk about her/his own opinions. Next, this member again selected randomly another one.

Thanks to this visualized method, I saw the meeting went more exciting with a lot of issues were discussed easily.

Styling Sort Icons Using Font Awesome for Primefaces' Data Table

So far, Primefaces has used image sprites for displaying the sort icons. This leads to a problem if we want to make a different style for these icons; for example, I would make the icon "arrow up" more blurry at the first time the table loading because I want to highlight the icon "arrow down". I found a way that I can replace these icons with Font Awesome icons. We will use "CSS Pseudo-classes" to achieve it. The hardest thing here is that we should handle displaying icons in different cases. There is a case both "arrow up" and "arrow down" showing and other case is only one of these icons is shown. .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s { background-image: none; margin-left: 5px; font-size: 1.1666em; position: relative; } .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s:not(.ui-icon-triangle-1-s)::before { content: "\f106"; font-family: "FontAwesome"; position: ...

Building a Wizard with Chain of Responsibility Pattern

What is the Idea? We want to create a page that there are some steps and each step has its own business. Users are able to click on a step and its status could be changed. Primefaces owns a component " Wizard " but it it quite hard for us in order to apply our very specific and complicated business domain logic on each step; even we cannot click on a step of this component. We somehow are able to use the component " TabView " works with a strong back-end mechanism. A backend mechanism! what do I mean? Yes, we need it because we want to abstract the behaviors of each step otherwise we will get trouble with many events handling. Obviously, each step has some behaviors such as "next", "back" and "switch' are the same and they are related to each other; but the business of these behaviors can be different totally. That is where the pattern "Chain of Responsibility" can be applied. Step by Step Building It! In this simple pr...

Updates to the Scrum Guide - The 5 Scrum Values

This article is available at blog.scrum.org , here I just quote my favorite points and give my comment at the end of this post. Ken Schwaber and Jeff Sutherland, the creators of Scrum delivered a webinar on their latest update to the Scrum Guide . The update was a simple one, adding the 5 values of Scrum to the Guide: These values sound easy? Well, there are many misunderstandings and common problems when applying these values. Here are some example: Value Misunderstanding Getting the value right Commitment Committing to something that you don’t understand because you are told to by your boss. Committing yourself to the team and Sprint Goal. Focus Focusing on keeping the customer happy Being focused on the sprint and its goal. Openness Telling everyone everything about all your work Highlighting when you have challenges and problems that are stopping you from success Respect Thinking you are helping the team by being a hero Helping peop...

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...

Multiple Inheritance of State and Implementation

Today, I was just curious about why an enum can not extend anything else. I took a look on the Oracle document here , and I found the answer is below: "All enums implicitly extend java.lang.Enum. Because a class can only extend one parent (see Declaring Classes), the Java language does not support multiple inheritance of state (see Multiple Inheritance of State, Implementation, and Type), and therefore an enum cannot extend anything else." I have been learned of it before. But, wait a sec...! Why Java does not support multiple inheritance of state? Since I have worked with other programming languages like C++, I was able to make a class extend some other classes. The short answer is to avoid the issues of multiple inheritance of state . I wonder if other programming languages have these below terms but Java does. Multiple inheritance of state It is the ability to inherit fields from multiple classes. There is a problem and Java avoids it. "For exa...
