BD-review

July 29th, 2009 bodom_lx No comments

BD-review is a dynamic website to allow people to review releases (albums, demos, EPs, singles) of (young, unsigned) music bands. The project is the outcome of the Internet Technologies course at the Faculty of Computer Science of the Free University of Bolzano.  The requirements of the project were to build a website using a small subset of JavaEE technologies, without the use of web-frameworks.

Therefore, this project is not really meant for production use. It was made as a strong, working and correct base for studying JavaEE academically. It should be useful for every student (also non-student) willing to have an overview on JSP and study it. The code is well-written, uses MVC, and the whole project is documented in detail in a 20+ pages report.

I encourage to read the PDF report of the project. It contains detailed information about the analysis and design phases, as well as the architecture description, screenshots, problems found etc. Please read also the README file. It contains configuration instructions.

There is a running demo located on the evaluation server of the course, but I think it will be removed soon.

Vision

The aim of the project is to build a dynamic website to allow people to review releases (albums, demos, EPs, singles) of (young, unsigned) music bands. Users will be able to signal interesting materials and review them, while other users will be able to comment the reviews, too.
This web 2.0-oriented application should allow unknown talented musicians to achieve a higher notoriety but also to improve their productions.

The Future

There will not be future developments for the project. It was not a real-life project but I will be very proud if you find it an useful example for learning JSP. You can also use it as a basis for developing a real project (also a University Project). You can do anything you want with BD-review, but please respect the license. I would be happy if you send me an email about your experience in using BD-review.

Unipoli

June 11th, 2009 bodom_lx No comments

Unipoli is a simple simulation of the very popular board game Monopoly by Hasbro. Unipoli is the Java outcome of the Programming Project course I followed in Academic Year 2007 – 2008.

I don’t know for how long the official project page will stay on Unibz servers, therefore I’m keeping this page on task3.

Project Members

  • Riccardo Buttarelli
  • Daniel Graziotin
  • Martin Leitgeb
  • Massimiliano Pergher

Mission Statement

This document was the first step made in facing the project:
The project will provide a simple simulation of the very popular board game Monopoly. Unipoli will allow a multiplayer experience (up to 8 human players) on the same machine but not over a network.
We will implement the classical Standard (Atlantic City version) Monopoly game board layout, produced by Charles Darrow, and later by Parker Brothers.
However, by virtue of being a virtual implementation of the real game, Unipoli will overtake some aspects of the real Monopoly game, giving to the players unique visual experiences. As example, we will highlight owned lands with the color associated to their owners. When a player decides to sell a property, the board will be obscured, leaving the lands owned by the player well visible.
Like in the original game, the purpose is to dominate the competition against the opponents, and be the last to survive. Due to time problems, we will not implement all the rules and game features. For example, hotels will not be included in our game version.

The GUI will consist of two main components:

  • A 2D top view of the game-board, that will occupy about the 80% of the window.
  • A sidebar containing information on players and the dice.

Players will be able to buy lands and build houses in case of monopoly. The opponents have to pay rents if a land is owned. There will be both factories and railroads.
Our game implementation will also feature the so-called Chance Cards.
There wonʼt be the possibility to play as the Bank. Money will just be considered as a number which increases and decreases. Therefore, a graphical representation of paper money is not scheduled.

Unipoli

June 6th, 2008 bodom_lx No comments

We finally finished our university project, Unipoli. The Java implementation of the famous Monopoly game by Hasbro has been released under GPLv3 (yes it’s free software) . You can have a look at the source code, simple but elegant, written using coding standards, following xP practices and Scrum software development process (at least we tried to follow them).
On the project site you will find useful documentation, too: Vision Statement, User Stories, Noun Extraction, Product Backlog, UML Classes, Hierarchy and Relations, UML class diagram, Javadoc.
The game has been written for Programming Project course.

The product backlog becomes multicolored!

May 14th, 2008 bodom_lx No comments

I’m very proud of this, after so many problems encountered during the first two months of development, our product backlog begins to turn green and yellow!

Anyway, I think that Scrum Method is not the best software development process that we could have adopted, I will espress my thoughts during the exam and I will publish them

A simple, tiny, Unix Shell written in C language, opensource

May 9th, 2008 bodom_lx No comments

BD-shell is a project I started about a month ago, which aims to implement a tiny, simple, clean unix shell written in C language. It’s an academic project. The Operating Systems Course at my University requires this project as part of the assesment.
I decided to publish the source code and to release it under the GPL, for two reasons:

  1. Free software is better! Others can learn something from what I learned
  2. Free software is better! I can learn something from what others learned

As always, I accept every kind of suggestions!

Learn more about the project and download the code at this page:

BD-shell

April 21st, 2008 bodom_lx No comments

BD-shell (a.k.a. bdsh) is a tiny Unix shell written in C. It’s a project required for the Operating System Course at my University.
It is written using a clean coding style, following xP coding standard philosophy.
Version 1.0 is the release that satisfies all the course requirements!

Features

Cool Features

  • Lightweight
  • Implements real Job Control
  • Clear and understandable code, ideal for Academic (and personal) studies
  • Makes use of various system calls, signals, signal handlers, user input handling, data structures implementation
  • Free Software!

Cool Features NOT present (but may be in future)

  • No command history present
  • No command/filename auto completion
  • No wildcars
  • No command piping, just a single command can be launched at a time
  • Put everything else here.
These are the requirements asked by the teaching professor. The complete project description page is located at http://www.inf.unibz.it/~david/os/project.html
The shell must be able to do the following:

  1. to read commands from standard input and execute them in a loop until a
    built-in command exit is issued (we call these processes the foreground processes; there is always at most one of these at any particular time);
  2. be able to redirect the standard input and output of commands by prefixing them with built-in commands in file and out file;
  3. be able to terminate (involuntarily) the foreground process when user presses ^C and return back to the mini-shell;
  4. be able to interrupt the foreground process temporarily, when user presses ^Z, returning to the mini-shell;
  5. be able to execute any number of processes in background (i.e., in parallel with the foreground process), including in particular, the ability to start another process while a process has been temporarily suspended;
  6. inform the user when the background process finishes or is
    waiting for an input from the terminal;
  7. be able to inform the user what commands are executing in the background by issuing the built-in command jobs, this should include information about the state of the process (i.e., suspended, background, waiting for input, etc.) and about what file(s) is the background process using for standard input and output);
  8. be able to terminate involuntarily a background processes by issuing the built-in command kill job-number.
  9. to be able to resume a process or to make a background process into the foreground process (i.e., the one that currently interacts with the terminal) by issuing the fg job-number command.

Download:

  • 2008-09-14 – version 1.0.0.
    • fixed synchronization bug in putJobBackground() that made not notify background processes requesting input (in some situations)

    Known Bugs:

    • Lots of! I consider bdsh-1.0.0 stable because it covers ALL requirements of the course and does them whell on various Unix systems. So it works, but commands like “in non_existent_file cat” won’t work and will crash it!

    What will be next?

    • I don’t know. I may consider a 1.0.1 release to fix future bugs. I may also think to add cool features to make the shell complete. I hope I will have the time for it. You can also do it by yourself and send me the code
  • 2008-09-13 – version 1.0.0 Release Candidate 2.
    Changes from beta 1 / release candidate 1

    • removed gcc O3 flag from makefile
    • lots of bugs fixed in functions operating on the list of jobs
    • improvements in launchJob() when dealing with background commands
    • bug in putJobBackground() that made the shell crash has been fixed
    • killJob() now sends a SIGKILL
    • bugs fixed in signalHandler_child()
    • Code formatted using astyle (linux style)
    • A couple of variables renamed
    • Various usleep() removed

    Known Bugs:

    • So many =) This is a shell made for Academic purposes, not for production use!
  • 2008-07-30 – version 1.0.0 beta1.
    Characteristics:

    • First beta release of the final version
    • Every requirement has been covered
    • Real Job-Control implemented
    • About every function of bdsh.c has been rewritten
    • New source directory layout, very clean
    • Some documentation and makefile
    • IMPORTANT! this has to be considered a bug hunting release! Please report me any bugs
  • 2008-06-05 – version 0.7.1, corrects the linked list bug of version 0.7.0
  • 2008-05-09 – version 0.7.0.
    UPDATE 2008-06-05: there is a bug in the list handling, the shell crashes when using the standard input redirection. Please download version 0.7.1, which corrects the problem.
    Characteristics:
    • Cleaner code!
    • Lots of bugs fixed!
    • reads commands from standard input and executes them in a loop until a built-in command exit is issued
    • redirects STDIN and STDOUT of commands by prefixing them with built-in commands in file and out file
    • terminates (involuntarily) the foreground process when user presses ^C and return back to the shell
    • executes any number of processes in background (i.e., in parallel with the foreground process)
    • informs the user when the background process finishes
    • informs the user what commands are executing in the background by issuing the built-in command jobs
    • terminates involuntarily a background processes by issuing the built-in command kill job-number.
  • Due to a lots of compatibility issues with Gnu/Linux (the shell has been developed under Mac Os X), the final released has been delayed to mid-September. Sorry for this, I encountered so many problems the day before project presentation, that I decided to present it during the next exam session. I switched back to Gnu/Linux, too :)
  • Final release is scheduled on 2008-06-26, as the project deadline is 2008-06-25. The release will
    satisfy all the requirements, and as addition:

    • Execution system totally rewritten (e.g. one single short function that handles everything)
    • A Job Control will be implemented
    • Processes in foreground will really be in foreground, there are a lot of things that we did not learn during the course, like tcsetpgrp()
    • Some functions in utils.h will be deleted and optimized
    • Cleaner and clearer code!
  • 2008-04-21 – version 0.0.1
    Characteristics:
    • Modular code, divided in 3 files: bdsh.c, utils.h, headers.h
    • Clean user input from a char buffer to an array of strings
    • Built-in commands: exit (exits from the shell), cd (changes directory), in <filename> command (redirects STDIN of command from <filename>), out <filename> command (redirects STDOUT of command to <filename>)
    • Makes use of fork() to read commands from standard input and execute them
