FastAPI – Building High-performing Python APIs

FastAPI – Building High-performing Python APIs

FastAPI is a fast, highly intuitive and well-documented API framework based on Starlette. Despite being relatively new, it’s gaining strong adoption by the developer community. Following the UNIX philosophy of “doing one thing, and doing it well”, separating parts of the application according to their task improves code readability

Tracing the Python GIL (Global Interpreter Lock)

Tracing the Python GIL (Global Interpreter Lock)

Why the GIL matters Edit: The original article, in its entirety appears here. There are plenty of articles explaining why the Python GIL (The Global Interpreter Lock) exists1, and why it is there. The TLDR version is: the GIL prevents multithreaded pure Python code from using multiple CPU cores. However,

Hiding execution of unsigned code in system threads

Hiding execution of unsigned code in system threads

Anti-cheat development is, by nature, reactive; anti-cheats exist to respond to and thwart a videogame’s population of cheaters. For instance, a videogame with an exceedingly low amount of cheaters would have little need for an anti-cheat, while a videogame rife with cheaters would have a clear need for an

Building a runtime reflection system for Rust (Part 3)

Introduction Welcome to the third and final installment of our series on how we implemented a runtime reflection system in Rust. So far, we’ve shown how we came up with a fairly simple Class and Instance model for thinking about runtime Rust classes. In Part 1, we used these

Building a runtime reflection system for Rust (Part 2)

Introduction This is Part 2 in our blog series on our experience building a runtime reflection system in Rust for our policy engine, oso. Part 1 can be found here. In Part 1, we built a simple class system, with a metaclass struct called Class to track type information. We

Building a runtime reflection system for Rust (Part 1)

Introduction We’re building oso, an open source policy engine for authorization. You can use oso to separate authorization logic from application code by writing policies in our declarative language, called Polar. oso is built to be embedded directly in the application, which means you can pass in application objects,
