  • I have two key points to understand any large codebase:

    • Start with the entry point. Check the initialization process. It will most likely tell you what other parts of the code are crucial to the application. Start digging into those parts that are mentioned in the initialization process. Rinse and repeat for their dependencies which might look important. Just read and take notes if necessary. Try to understand how the application gets its stuff running. Don’t spend too much time on a specific part, just get a broad understanding and how it all flows.
    • After the first step, you should start seeing some sort of patterns to how the software is made: repeating principles, common practices, overall architecture. This is the point when you should be confident enough to introduce changes to the software, therefore you should have a build environment which guarantees the application works. If it doesn’t, have someone in the team help you to get it running without any changes to the codebase. Don’t make changes until you have a working build environment.

    With both done, you should already be comfortable enough to start modifying the application.

    I cannot stress enough how many developers I’ve seen trying to dig into random parts of the code knowing nothing where or how it all begins, making it super-problematic to add new features. Yeah they can fix a bug or two, but the biggest issues start when they try to implement something new.














  • Yeah dev home is pretty much useless at this point.

    Back when it just launched, they marketed it as it would introduce cool stuff to developers like, what I’m waiting for the most, git repositories Explorer integration. But all we have is a constantly crashing app and two extra widgets for the widget panel.

    Dev drives are also cool but they’re the part of Windows anyway, no dev home needed.
