ChkDB is rule-based data checking software for Oracle, plus files that define rule-sets and data domains (tables/views to be checked). The software is a PL/SQL package and some SQL scripts. There is currently no GUI front-end. For oil and gas data, there are domains and rulesets for well-header, drill-stem-test, and seismic-inventory data.
furious_tv is a PVR backend that uses an SQLite database to hold XMLTV listings data. Using that data, it can automatically execute commands to record TV shows off of a capture device (multiple capture devices are supported). If Shuriken is installed, furious_tv can also automatically power the system on/off for recordings to save power.
updyn is a shell script that updates a dynamic DNS service with the current IP address. It will work with any dynamic DNS service that allows you to call a URL to update the DNS. It works behind a router when an external IP address is different from internal IP, optional minimum time check, does not update unless your actual IP is different from your assigned IP, and can be set to update the DNS every set number of days whether or not your IP has changed.
ptr.h is a C++ smart pointer template which uses semaphores to for non-blocking thread safe reference counted memory management. It differs from many smart pointers in that the delete mechanism is a generic parameterized template, so it works for arrays and other resoures like file descriptors or database connections as well. On supported platforms, the semaphore is replaced with an unsigned long and the inline assembly necessary to atomically increment and decrement the reference.
The Reverse Trace Garbage Collector for C++ is a memory manager for C++ that automatically reclaims dynamically allocated objects that are no longer in use. The algorithm is precise and only scans memory blocks when root references are broken (as opposed to scanning the whole stack and heap for unreferenenced blocks). It also reclaims memory incrementally with separate threads so that applications are not paused when it is active.
PP3 creates celestial charts. It generates resolution-independent maps of very high graphical quality. They can be used, for example, as illustrations in books or on Web pages. It is possible to change many parameters, and arbitrary text can be placed on the maps. The output formats are EPS or PDF.
exrtools is a set of simple command line utilities for manipulating high dynamic range images in OpenEXR format. It was developed to help experiment with batch processing of HDR images for tone mapping. Each application is small and reasonably self-contained so that the source code may be of most value to others.
