TagEventor is a project to enable radically simple computer usage by creating physical-object-based user interfaces. It does this using commercially available (and relatively cheap), standardized RFID technology in the form of small, simple USB connected contacted card/tag readers and small, cheap tags. The project was started based on products available from the "touchatag" company, which has clients for Windows and Mac, and run their own Web service to enable many interesting Web-based applications. However, no simple, lightweight Linux client was available, and the Web focus meant that some client-focused functionality was not possible. The software is currently a daemon that monitors the presence of one or more RFID tags on a connected reader and generates "system events" when tags are placed on it or removed from it.
dao-zero is a tiny Java bean used to reduce the source of a persistence tier based on Spring's iBatis support. The usual way to use iBatis in Spring is to write code and invoke the iBatis API explicitly. dao-zero invokes the iBatis API for the developer automatically, without the need to write implementation code. It will implement DAO interfaces automatically and invoke iBatis SQL mapped statements for you. You can use it to replace your DAO bean class directly.
System Watchdog is a program that is designed to monitor a collection of Linux systems. It is configured to collect data on each monitored system at 5-minute intervals and build historical graphs using RRDTool. By default, it will gather statistics on CPU, memory, disk, and network usage. It also will attempt to monitor temperature and power settings. System Watchdog uses the paramiko module to ssh to all monitored systems. To access monitored systems, threads are implemented to access each remote host. After all threads have completed, watchdog will build a summary landing page to display the current status of each host, with links to a hardware inventory and resource graphs of each host.
MQRC2-GUI is an application that can interpret an MQ reason code number (i.e. 2035), MQ reason code symbol (i.e. MQRC_OBJECT_IN_USE) or AMQ message number (i.e. AMQ4005) and display the relevant information from the WebSphere MQ Messages manual. MQRC2-GUI requires Java Runtime Environment (JRE) 1.4 or higher and can run on any platform that has a JRE or JDK installed.
treap.py is a treap implementation for Python. A treap is a hybrid of a binary tree and a binary heap that is self-balancing and is O(nlog2(n)) for most operations, including deleting a value, inserting a value, finding the least value, and finding the greatest value. This particular treap implementation looks like a dictionary to the caller, but it also supports getting an ordered list (forward or reverse) in O(n) time. The code is available as pure Python (should run on about any Python implementation supporting generators, but was tested on CPython 2.6) or as part Python and part Cython for performance. The version with Cython should run on CPython or Unladen Swallow, but was only tested on CPython 2.6.
Chaplin ACT is a Java class transformer which brings several modern language concepts into Java: contexts, composites, roles, traits (mixins), runtime type conversion, dynamic method signatures, method and field aggregators, etc. Using these concepts makes designing loosely-coupled applications and writing cohesive code easier. Chaplin can work either as a JVM agent or as a post-compilation class transformer. It does not introduce any new syntax. All functionality is implemented by means of the standard Java language elements.
