 to have

    this big app? December 26, 2013 Developing complex web applications (not particularly Rails apps) is a tricky task. You write your models, controllers, services and optimize application architecture iteratively. But even with the great architecture when your application starts to be huge, bad things happen. Every little feature you’ll add will cost you precious time - tests must pass on your CI and workers needs to be reloaded every time you deploy. In addition, you begin to realize that mental overhead with keeping modules separated is huge - you have to remember a lot of things to keep it in right fashion. Ultimately, working on a project is hard, TDD technique is inefficient to use and you’re not happy at all with your code.

    imminent privacy overhaul means that we all have to become more diligent about what data we collect, how we collect it, and what we do with it. In our turbulent times, these privacy obligations are about ethics as well as law. Web developers have a major role to play here. After all, healthy data protection practice is as much about the development side — code, data, and security — as it is about the business side of process, information, and strategy.
