Dewald Esterhuizen

What is ? The title actually refers to a long running inside joke. Often people pronounce my first name in such a way it ends up sounding similar to the word ‘Default’ (how would you pronounce Dewald?). Add to that earning a living as a programmer and the result becomes :)

The intention behind this website is to serve as a platform for the open source projects I’m involved in. Open source, aka free stuff! If you want to collaborate on an open source project let me know in the comments section, or contact me via twitter @DefaultSoftware

You don’t need to be a programmer to be part of an open source project. If you are knowledgeable and have experience in a specialised field, or even if you have creative/innovative ideas you can contribute to the open source community without having to write any code.

    Hi Default
    I would love to contribute to an Open Source c# project. I’m learning c# on and off at the moment but would be nice to work with others as well.
    Hope to hear from you.
    Cheers
    Matt

      Hi there Matt!

      Learning a new programming language can be a bit daunting, I remember feeling like I won’t be able to do much until I know everything. It turns out I’ll probably never be able to know everything there is to know about C#, but I can still try :)

      Depending on your current skill/experience level I would recommend http://codeplex.com or http://sourceforge.net as a good starting point when looking for open source projects to join.

      Often when reading programming books I find myself placing more importance on finishing a book as opposed to doing a thorough study of the book’s content. To ensure proper learning I’ve lately gotten into the habit of posting articles on my blog as I discover something new. When writing an article I develop sample code, do research and thus become better acquainted with the relevant topic.

      Code samples might not be fully functioning and complete applications but I consider them to still be classified as open source. Posting articles and code samples also serves as a method improving your reputation within the programming community and illustrates being knowledgeable in the topics your articles relate to.

      Greetings,
      Dewald

        Thanks Dewald. I’m just applying to join a few projects at codeplex.com to see what happens. I might start my own project though and open it up to all Developers – that would be so cool!!! Do you find that there are ever arguments if someone says that their code is not good enough or arguments of who should write which parts?

        Thanks so much for help me – you’ve been priceless

        cheers Matt

        Hi Matt,

        The project license refers to the license under which you grant users the right to use/change/distribute your software and/or source code. You can read up on it here http://opensource.org/licenses

        I prefer the Microsoft Public License: http://www.microsoft.com/en-us/openness/licenses.aspx

        What is your user/profile name at codeplex.com?

        Thanks,
        Dewald :)

        Hi

        My username is jmatty2000

        I’ve randomly picked the Microsoft public licence now. Not sure how to be in a comfortable position to upload source code though if you could advise – do I need Tortoise SVN which it seems to recommend.

        I don’t have a project at the moment – do you think I should just create a blank one and up load the folder as a starting point?

        Cheers Matt

    Which software do I use to submit some project files?
