V3SP3R
AI Flipper control
V3SP3R is an experimental open-source project focused on integrating artificial intelligence with Flipper Zero control, aiming to create a more autonomous and intelligent interaction layer for hardware-based security tools. The project explores the concept of AI-assisted device control, where an intelligent system can interpret commands, automate workflows, and potentially orchestrate complex sequences of actions across Flipper functionalities. It is part of a broader ecosystem of projects by the same author that investigate prompt engineering, agent-based systems, and unconventional AI interaction paradigms. V3SP3R appears to emphasize automation and abstraction, reducing the need for manual device interaction by allowing higher-level instructions to drive hardware behavior. The project aligns with emerging trends in combining AI agents with physical tools, effectively bridging software intelligence and hardware execution. -

Vespa
The open big data serving engine
Make AI-driven decisions using your data, in real-time. At any scale, with unbeatable performance. Vespa is a full-featured text search engine and supports both regular text search and fast approximate vector search (ANN). This makes it easy to create high-performing search applications at any scale, whether you want to use traditional techniques or a modern vector-based approach. You can even combine both approaches efficiently in the same query, something no other engine can do. Recommendation, personalization and targeting involves evaluating recommender models over content items to select the best ones. Vespa lets you build applications which does this online, typically combining fast vector search and filtering with evaluation of machine-learned models over the items. This makes it possible to make recommendations specifically for each user or situation, using completely up to date information. -

google-java-format
Reformats Java source code to comply with Google Java Style
google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button. -

libsu
A complete solution for apps using root permissions
libsu is a modern Android library that provides a safe, convenient API for executing commands with root privileges and interacting with the Android shell. Instead of ad-hoc Runtime.exec calls, it offers structured sessions, proper I/O streams, and lifecycle handling that works reliably across devices. The library focuses on developer ergonomics: thread-safe helpers, Kotlin-friendly APIs, and utilities for file operations, process management, and parcelable data transfer. It’s designed to interoperate smoothly with Magisk-based root environments while degrading gracefully on non-rooted devices when possible. Attention is given to security and correctness—avoiding resource leaks, handling timeouts, and containing elevated operations to explicit scopes. For apps that legitimately need privileged automation or maintenance tasks, libsu becomes the backbone that keeps the “root” parts predictable and testable. -
