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 …

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:

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.

Meaningful Names - Code Review Checklist with Example

"Names are everywhere in software". "The hardest thing about choosing good names is that it requires good descriptive skills"[1]. In my previous post, I emphasized that we should take care our code, so now let's start with naming.
