AppDynamics an application performance management solution for mission-critical Java applications. It can organize user requests and business transactions, monitor business transaction health, identify and diagnose slow requests, identify and diagnose errors, and drill down. It is built from the ground up for highly distributed service-oriented environments. It has fast root cause diagnostics at the method/class level, but creates no more than 2% overhead, even in high-volume production deployments. It can not only manage applications, but dynamically scale them in cloud and virtual environments.
Cyclone is a low-level network toolkit that provides support for HTTP 1.1 in an API very similar to the one implemented by the Tornado Web server. It has localization based on gettext with pluralization support, native support for XMLRPC and JSONRPC, native support for WebSockets (drafts 75 and 76), decent support for sending plain text or HTML email with TLS and attachments, built-in support for Redis, and support for HTTP authentication.
Treba is a commandline tool for training, decoding, and calculating with weighted (probabilistic) finite state automata (WFSA/PFSA). Training algorithms include Baum-Welch (EM), Viterbi training, and Baum-Welch augmented with deterministic annealing. Treba is optimized for speed and numerical stability, and training algorithms can be run multi-threaded on hardware with multiple cores/CPUs. Forward, backward, and Viterbi decoding are supported. Automata for training/decoding are read from a text file, or can be generated randomly or with uniform transition probabilities with different topologies (ergodic or fully connected, Bakis or left-to-right, or deterministic). Observations used for training or decoding are read from text files compatible with AT&T finite state tools and OpenFST.
iSAM is an optimization library for sparse nonlinear problems as encountered in simultaneous localization and mapping (SLAM) in mobile robotics. The iSAM library provides efficient algorithms for batch and incremental optimization, recovering the exact least-squares solution. The library can easily be extended to new problems, and functionality for often encountered 2D and 3D SLAM problems is already provided.
Resize Magic is an application that resizes images with a high quality algorithm, similar to the Lanczos algorithm used by other programs, with some modifications. It can be used to batch resize images, and preserves Exif data and ICC color profiles. A Photoshop plugin is also available as a commercial product.
ReplicaNet is an object oriented C++ library for developers of applications that require a stable and low maintenance middleware solution to networking. Any project that is designed to use a network of machines, such as multiplayer computer games, need to very carefully consider how to approach the design problems associated with networking. It includes support for binary difference patch creation and delivery, backend availability and TitleID verification, Internet CD/license key verification, NAT detection, advertising and querying of sessions, user accounts, friends lists, game invites, chat rooms, persistent data storage, and statistics and ranking.
