Chef is a systems integration framework, built to bring the benefits of configuration management to your entire infrastructure. With Chef, you can manage your servers by writing code, not by running commands (via Cookbooks), integrate tightly with your applications, databases, LDAP directories, and more (via Libraries), and easily configure applications that require knowledge about your entire infrastructure ("What systems are running my application?" "What is the current master database server?").
Graylog2 is an syslog implementation that stores logs in MongoDB. Messages are accepted via TCP or UDP. A Web interface allows you to view the log messages. It also implements GELF, the Graylog Extended Log Format, which is a simple JSON string that allows you to send long and structured syslog messages, which is very useful for customized application log monitoring.
LaunchControl is a fully-featured launchd(8) frontend allowing you to manage and debug system and user services on your Mac. It provides everything you need to load, unload, start, create, edit, remove, or troubleshoot launch services. It supports all documented features of launchd, reports potential problems before a job is even started, and makes sure you always create valid configurations. It supports user LaunchAgents and Global and System LaunchAgents/Daemons. It shows all services and their status at a glance, and misconfigured services are highlighted. You can enable or disable services, and find them with a job filter. Not just a plist editor, it provides a dedicated interface for every configuration key with an adaptive interface that displays only information relevant for the selected job.
Mole (Mobile Organic Localization Engine) provides room-level geoposition estimates using existing WiFi infrastructure. When you create an entry in the database by naming a room, your and other users' mobile devices will recognize when they are in that room. Other applications can poll or monitor the current room estimate and act accordingly, with context aware behavior. Because too much WiFi scanning drains batteries, it uses accelerometers and other tricks to keep scanning to a minimum while keeping update latency reasonable.
Multi Threaded Daemon - enhanced is a class that implements a daemon that can spawn multiple parallel threads. It includes a sample app to monitor a "queue" directory on the filesystem, and spawns up to "N" child processes to parse individual files from it. It is an enhanced version of the original Multithreaded Daemon class written by Benoit Perroud. This version provides several robustness improvements, adds support for handling signals (SIGTERM, SIGHUP), and a unique PID file to avoid starting multiple instances.
The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example.
