- Artificial Intelligence is increasingly integrated into various applications, particularly by corporations with significant financial resources.
- On-device AI models enhance user experience by providing fast, offline access for tasks like photo filtering and object detection.
- Microsoft's Seeing AI app serves as a notable example, offering accessibility features, including currency detection for visually impaired users.
- Android apps are packaged as APK files, which contain all necessary components, including AI model files.
- The currency detection model within Seeing AI appears to be encrypted, presenting challenges for direct access and analysis.
- Tools like apktool can be used to decompile APKs and inspect their contents, revealing encrypted files and potential AI models.
- TensorFlow Lite is identified as the framework used for running AI models in the Seeing AI app, which facilitates model loading and inference.
- Frida is introduced as a dynamic instrumentation toolkit that allows for the alteration of app behavior and method tracing.
- By using Frida, the author successfully extracted the currency detection model from the app, validating its contents with a neural network visualization tool.
- The article emphasizes the importance of intellectual property rights regarding AI models, advising users to obtain permission before using or modifying extracted models.

When people say Rust is a “safe language”, they often mean memory safety. And while memory safety is a great start, it’s far from all it takes to build robust applications.

I write type safe generic data structures in C using a technique that I haven't seen elsewhere. It involves unions and typeof, but we'll get to that. My approach works for any type of data structure: maps, arrays, binary trees… but for this article I illustrate the ideas by implementing a basic linked list.

This tech demo explores creating a destructible, procedurally generated spherical world with Minecraft-style blocks in the Unity engine. The central challenge involves mapping a cubic grid onto a sphere without major distortion, which is solved using a "quad sphere" technique that projects a cube's faces outward. To handle distortion at varying depths, the planet is built from concentric shells, where outer layers have more blocks than inner ones to keep block size consistent. The project also required developing custom player gravity that pulls towards the planet's core, using 3D noise for seamless terrain generation, and creating a system for placing structures that can navigate the complex geometry between the planet's different sectors and shells.
