One of the main reasons that stop people to write Python C extensions and even attempt to contribute to CPython is due to the fact that you need to know another programming language, C. Wait, don't go! don't be scared by the fact that you will hear about C, this talks objective is not that! but only to learn the essential bits to get more comfortable around CPython. By understanding the internals, you will feel like the same as that time in your childhood when you took something apart, then re-assemble it again and it worked (if that was not the case, this will be your first time I promise). During this talk, you will go on a journey to understand how Python works, and which are the places you can look to understand the implementation of different Python details, from the whole interpretation process, until look what's lies under the module/types functions you use everyday. You will get the power to add new functionality to Python and even how to create your first C-based extension module. If you are not familiar with C, don't worry, I will guide you every time some C code is shown, and if you know some C, then you will be able to sit back and relax during this ride.

API security sounds simple – keeping the applications and microservices that businesses rely on safe from cybercriminals and without vulnerabilities. But it is much more complicated than that in practice. Especially in the past year as traditionally brick and mortar businesses flocked to virtual environments, the sheer number of APIs in operation vastly increased – often to the point where it is difficult for a business to truly know and have visibility into every API that interacts with their organization. A recent report by Salt Security shows that 91% of organizations suffered an API-related problem in the last year, and more than half (54%) reported finding vulnerabilities in their APIs, 46% pointed to authentication issues, and 20% described problems caused by bots and data scraping tools.

Often developers design APIs that expose more than is needed – unnecessary fields, redundant relationships, and endpoints that no one asked for. These kinds of practices later on introduce communication overhead, extra maintenance costs, negative performance impacts, and waste time that could have been spent better otherwise. We'll walk through how to design minimal APIs that are straight forward to use, and that are exactly what our consumers need! ***
