Announcing Dycapo 0.0.2

As promised, Dycapo 0.0.2 is out.

Dycapo will be an open client (mobile)/server system that will improve travel experiences of users in a city. The system will let people to define a destination on their mobile phone. DyCaPo will suggest and arrange trips by either using the Public Transport Service or Carpooling volunteers.
That is, DyCaPo will implement full Dynamic Carpooling functionalities as well as static approaches.

More information and download on the official page.

Here are the release notes and the changes since 0.0.1:

RELEASE NOTES
***************
2010-01-10 Daniel Graziotin 
Dycapo 0.0.2 is just for _showing_out_some_functionalities_ of the system and testing the underlying technologies. Dycapo 0.0.2 incorporates and shows:
* OpenTrip Core adoption and OpenTrip Dynamic data structures proposal (in Django Model format)
* Use of XML-RPC with Django (rpc4django over HTTP and HTTPS)
* (Sort of) integration of Dycapo models with Django and rpc4django
* Authentication
* Insertion of a trip by a driver
* Start of a trip by a driver
* Search of a trip by a rider
* Send a ride request to a driver
* Let the driver accept the ride request
No one exported XML-RPC function will surely be included in the final API! No one exported XML-RPC function is either optimized or completely working!
Code is (somewhat) documented. Expect a completely better work for 0.1.0 :)

CHANGES SINCE 0.0.1
***************
Some refactoring to make the code cleaner.
Lots of bugs fixed.
Test suite rewritten and (finally) fully working.

models.py:
- added utility methods (i.e. __unicode__ and to_xmlrpc)
- use of OpenTrip id proposal instead of Django id
- addition of fields to Participation model, regarding a ride request and a request accepted

trip.py:
this module has been splitted in four files:
- driver.py - holds all the XML-RPC methods that a Driver needs.
- rider.py - holds all the XML-RPC methods that a Rider needs.
- commin.py - will hold all the XML-RPC methods shared by Rider and Driver
- utils.py - holds some utility functions.

driver.py (formerly trip.py):
- added check_ride_requests(trip) - checks for ride requests
- added accept_ride_request(trip, person) - for accepting a Rider

rider.py (formerly trip.py):
- added request_ride(trip) - sends a ride request to a trip

tests/:
- Cleaner code and better organization
- Added test_all_simple.py - creates a Driver and a Rider with the same destination as target
- test_all.py - creates 3 drivers and 5 riders with random locations as target

2009 final considerations. 2010 year of the Phoenix?

About a year after the creation of bd-theme-zen Wordpress theme, I decided to switch to a new theme. The new theme is monochrome

The reasons behind are simple: unfortunately, 2009 has totally been not a Zen year for me. Many things have not gone as I thought they should have been. Many other important things have been melted. Lot of things have changed.

I hope 2010 will be the year of the Phoenix, in which everything aggressively changes again and turns better. For everyone, for sure.

Therefore, I decided to switch to a new theme, monochrome by mono-lab.net. This theme is very modern, yet minimalistic and elegant. And surely, more nice-looking than those themes written by me.
I’m still happy with bd-theme-zen, I liked its initial orange version and I appreciated the glacial blue one I decided to switch to around August (the color switch was also significant for me).

But this is not time for being Zen. It is time to be reactive.

I wish everybody a fucking explosive 2010.

For those of you asking if I was spending my time to write this post on 2009-12-31 at 00.00: I wrote this post on 2009-12-26 and scheduled the publish to the beginning of the new Year.

Dycapo, road to 0.0.1

I’m doing some refactoring to the code and writing some useful documentation for the first pre-alpha-dontuse version of Dycapo (a.k.a. DyCaPo – Dynamic CarPooling system).
Dycapo 0.0.1 will only be for illustrating some functionalities of the system and the integration of the technologies.
The following is an explanation of our version codes:

  • 0.0.x releases are all pre-alpha-dontuse releases, to only illustrate some functionalities.
    API will likely change very often.
  • 0.x.x releases are still alpha-releases, that cover some internal development cycles but have
    important features that will appear on a stable releases. API for the important parts of the
    project will likely not be changed.
  • 1.0.0 will be considered a stable release that can be used for testing in a small reality. API
    will be frozen.

Update: first UML diagrams, some implementation thoughts

My third meeting at FBK is about to end. Today we discussed about some use-case, sequence and class diagrams I wrote during the week. Obviously there were lots of changes after the discussion and I will post them as soon as I’ve updated them. For the next time I will take a look at some implementation issues. The client side could be written using Android while for the server side we are seriously looking at Python and Django. It would be very interesting! For the communication, we are reasoning about XML-RPC, SOAP or a personalized Restful API. OpenTrip protocol might not be included in our implementation, as we don’t have the time to parse non-standard XML and adapt the system to use it. But this is not a final decision.
I will also write some simple mockups to test all the possible combinations.

Introduction To Software Testing

Elements and Concepts – A brief overview

Download PDF version of the whole document. You can browse the article online but I encourage the download of the PDF since it is written with accuracy.

Introduction

This document contains some basic concepts and definitions about software testing. It has been written for studying a part of the Software Engineering Project course at my University. It is composed by a summary of the intersection of more than 10 different sources, all of which are cited. If you feel that some contents of this publication belong to your intellectual property and it is not cited, please contact the author who is willing to correct any mistake.

The first part of the paper focuses on the definition of the most important key aspects of software testing. Then some information about input partitioning are given. What follows is a research about code coverage and two useful and famous tools, Control-flow coverage and Data-flow analysis. A complete example on using those tools is then given. The second half of the document also contains the definition of the most important software testing practices.

The goal of this tiny document is to clarify key terms and therefore become a base start for the reader to go in deep with the interested topics. Another goal is to give a simple but clear example about data flow analysis, as I realized that not all the people understand the examples around the Net.

Software Testing

Software Testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test, with respect to the context in which it is intended to operate. Software Testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs. It can also be stated as the process of validating and verifying that a software program/application/product meets the business and technical requirements that guided its design and development, so that it works as expected and can be implemented with the same characteristics. 1

Finally, the site has entered top 20000 Netcraft Most Visited Web Sites

It is always a great satisfaction to reach a goal. It took me about 3 years but I finally did it!
Today bd-things.net entered top 20k in Netcraft Most Visited Websites, at position 19058!
On September I desired to re-enter top 30k in about a year after the domain name change .
8 months after I reached a even better result.

I took two screenshots of the event , because I don’t think that this will happen so much often in my life :)

bd-thingsnet_top_20k_netcraft_2

bd-things_top_20k_netcraft_1

I would like to thank all the visitors of bd-things.net for their support, even if I would be happier to see more comments that would surely help to improve my articles.

In something more than a month I will publish 3 project source codes: a C++ task manager, a simple dynamic website using Java EE5 and a C (subset) compiler. All of them started as University Projects. The first program will surely be expanded and improved after the publish of the source code. But before that time, I have to study hard for ca. 20 deadlines I must accomplish. See you again.
