Software Craftsmanship by Sandro Mancuso


My first time to know about the term "Software Craftsmanship" is from Agile Tour Vietnam 2015. I finally read this book written by Sandro Mancuso who I met at this event.

Software Craftsmanship is a metaphor for software development: software as a craft and developers as blacksmiths. In other words, Software Craftsmanship is about professionalism in software development.

The Software Craftsmanship manifesto:
  1. Not only working software, but also well-crafted software: regardless how old the application is, developers can understand it easily; high an reliable test coverage, clear and simple design, business language well expressed in the code.
  2. Not only responding to change, but also steadily adding value: constantly improving the structure of the code, keeping it clean, extendable, testable, and easy to maintain; always leave the code cleaner than we found it.
  3. Not only individuals and interactions, but also a community of professionals: we are responsible for preparing the next generation of craftsmen; writing blogs, contributing to open source, making our code publicly available, becoming part of our local communities, and pair programming with other developers.
  4. Not only customer collaboration, but also productive partnership: software craftsman are not factory workers, they want to actively contribute to the success of the project, questioning requirements, understanding the business, proposing improvements and productively partnering with the customers or employers.
The Software Craftsmanship attitude:
  1. We own our career. "Who is in charge of our career and our professional future?"
  2. Keeping ourselves up to date: books, blogs, technical websites
  3. Know who to follow: help us to filter the entire amount of information we have online or in physical books.
  4. Practice, practice, practice: TDD, Katas, pet project(s), open source, pair programming
  5. Socialise: follows the manifesto "Not only individuals and interactions, but also a community of professionals"
  6. Deliberate discovery: the biggest mistake that we, software professionals, can make is not accepting that we don't know what we don't know.

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 .

Make simple music program with beep(freq, duration) with Pascal

Pascal is my first programing language when I have studied in high school. It was really exciting for me. :) The Pascal programming language was created by Niklaus Wirth in 1970. It was named after Blaise Pascal, a famous French Mathematician. It was made as a language to teach programming and to be reliable and efficient. Pascal has since become more than just an academic language and is now used commercially . I tried to make a simple music program by using Lazarus IDE on MS Window 7, 64-bit. It frustrated me a few times how difficulty to use Sound command to make a sound. Sound did not work on my compiler and my platform anymore. So far, I just could use beep(freq, duration) from window unit to implement my work. Here is my code. ;) program mysong; uses Windows, crt; const C: Integer = 512; { x = A * EXP(LN(2)/12)} C_: Integer = 542; D: Integer = 574; D_: Integer = 608; E: Integer = 644; F: Integer = 682; F_: Integer = 723; G: Integer = ...

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: ...

The HelloWorld example of JSF 2.2 with Myfaces

I just did by myself create a very simple app "HelloWorld" of JSF 2.2 with a concrete implementation Myfaces that we can use it later on for our further JSF trying out. I attached the source code link at the end part. Just follow these steps below: 1. Create a Maven project in Eclipse (Kepler) with a simple Java web application archetype "maven-archetype-webapp". Maven should be the best choice for managing the dependencies , so far. JSF is a web framework that is the reason why I chose the mentioned archetype for my example. 2. Import dependencies for JSF implementation - Myfaces (v2.2.10) into file pom.xml . The following code that is easy to find from  http://mvnrepository.com/  with key words "myfaces". <dependency> <groupId>org.apache.myfaces.core</groupId> <artifactId>myfaces-api</artifactId> <version>2.2.10</version> </dependency> <dependency> <groupId>org.apache.myfaces.core<...

  Introduction to OpenLDAP directory service "A directory is a specialized database specially designed for searching and browsing, in addition to supporting basic lookup and update functions" A directory service can be local, providing a restricted context; or global, providing service to a much broader context. Curlie is a good example of a directory service. LDAP (Lightweight Directory Access Protocol) is a protocol for accessing directory services , specifically X.500-based directory services. OpenLDAP is an open-source implementation of LDAP. Writing system software: code comments I have read Clean Code (by Uncle Bob) and I thought that I should void comments since the code it explains its implementation itself. That is right but not always true. In this post, the author categorized the comments into 9 types. Only "trivial comments" and "backup comments" are the ones that should be avoided. I myself agree with "writing good comments is harder tha...
