Service Guardian aims to protect servers against various things such as resource exhaustion and connection floods

Service Guardian aims to protect servers against various things such as resource exhaustion and connection floods. It can measure the number of connections to servers' ports and, after a grace time period, compares and sees if the host is still in violation of the specified settings. If a host is in violation of the settings, it will be filtered out and dropped via netfilter/iptables.

The Android Scripting Environment (ASE) brings scripting languages to Android

The Android Scripting Environment (ASE) brings scripting languages to Android by allowing you to edit and execute scripts and interactive interpreters directly on the Android device. These scripts have access to many of the APIs available to full-fledged Android applications, but with a greatly simplified interface that makes it easy to handle intents, start activities, make phone calls, send text messages, scan bar codes, poll location and sensor data, use text-to-speech, and more. Scripts can be run interactively in a terminal, started as a long running service, or started via Locale. Python, Perl, JRuby, Lua, BeanShell, and Bourne shell are currently supported.
