 Hi, everyone. I'm Julius Linus. I'm an Android developer here at NextCloud. And I'm going to give you guys an example of the effort Next Cloud has made to ensure the quality of the talk Android application. Just over all the speed here, refactoring. What is a strange word? What exactly does it mean? Well, in a nutshell, refactoring just means rewriting old code, also called legacy code, to new, modern code. So why care about refactoring? Well, if you don't refactor, tech depth happens. And tech depth is basically shortcuts, cutting corners, things we use to speed up development so that we can meet deadlines, so that our product managers are all happy, everyone's happy, people get paid. And one of the easiest ways to accumulate tech depth is through the use of third party libraries. Now, what is a library? Well, intuitively, just like how an actual library is filled with books that other people authored, a programming library is filled with programs that other people coded. And libraries speed up development time, drastically in some cases. And this app used a lot of them. And this made sense. Years ago, when the app was first being developed, and when these libraries are still fresh and new, and so still updated, it made sense to use them. They were maintained. But unfortunately, times change. Those libraries that were used at the beginning have since fallen to the state of disrepair. They're unmaintained. As you can see in that example, the last update was in 2020. Look at it. Some folders have been updated in seven years. That's not good. Not all libraries are created equal. They're only good when they're actively maintained by a third party. That's what makes open source useful, the separation of concerns. But unfortunately, because not all libraries are created equal, when they're not maintained, they just become bloat. TechDep, and TechDep needs to be repaid. Now, we at Talk and Android have a lot of TechDep to repay. And a lot of the libraries used in making the app have been outdated or abandoned. But we have made significant progress. Now, I'm not going to bore you all with the technical details of what exactly we've done. And to be honest, I'm sure you don't really care either way. But just to show you, we've done a lot, no doubt, and help by my genius co-workers, Andy and Michael. Sorry, Marcel, I'm so sorry. My genius co-workers, Andy and Marcel, who helped clear a lot of these. To do, we have practically everything. Development is pretty much never-ending. And Google doesn't help either, although you can also help us by contributing. Because it's true, we do do a lot of stuff here at Talk and Android. But this is just a small part of a bigger picture, a ground level view of the greater company-wide effort to deliver quality applications to our users, and especially to you. And you can help us too. You don't even need to learn how to code. Just by reviewing our app, notifying us of known issues, testing our bills and using it in production, you can help take NextCloud to the next level. Thank you.
