I was reading an article the other day talking about Agile and the idea of customer driven direction. Here’s an extract:
“One of the concerns that is sometimes expressed about Agile approaches is that they are ‘too customer-driven’, implying that customers are not always the best people to define the direction of a product or a change. So is ‘the customer always right’, and is it good Agile practice to ‘give the customer what they want’?”
What struct me about this is how people view their world. The assumption above is that both parties are attempting to do the same thing. Hence the discussion about is the customer best placed to make these decisions.
So here’s my take on it. Continue reading “Agile projects and customer direction”

In an earlier post I listed my Five ways to faster learning. Now all these ideas centered around having a plan on how you are going to learn. You need to decide where you are going and how you are going to get there. All make sense?
So where are you going? Continue reading “You don’t know what you don’t know”
- Focus on what you want/need to learn now – don’t read the book from cover to cover
- Create a learning plan of what you want to achieve
- Narrow your scope and learn about that, then move on
- Learn one thing at a time
- You can learn more studying once you have some practical experience to relate to
Now the real challenge in all this is that well known saying…
If you intend to build an application designed for more than a single user then you will need to provide a means for users to authenticate themselves. Authentication is the means for a user to provide information that allows your application to identify who you are.
The application will then typically use authorisation to check which functions and information you are allowed to access. To take a look at what is involved in an authentication system lets build a simple system to get you started.

When I first started out in programming I made the same mistake as I see countless people make when starting. I wrote code for me and that worked, and that was good enough for me. As time passed and the code I produced expanded and became more ambitious so my bad habits became more ingrained. I think it is something we all do; we all go through. It is not until we encounter an issue, a reason to change, that we appreciate the error of our ways. Continue reading “Java application dynamic configuration using a properties file”
If your java desktop application needs to store data in a database between sessions then a good solution is to embed a database into your solution. What this gives you is an application which installs the database as part of the application, builds the database tables and populates it with any initial data. This approach avoids the need for the user to install a database separately from the application.
Let’s takes a look at how to you might go about this. Continue reading “Java with SQLite embedded database”
