The Parsing Expression Grammar Template Library (PEGTL) is a C++0x library for creating parsers according to a Parsing Expression Grammar (PEG). Grammars are embedded as regular C++ code, created with template programming (not template meta programming). These hierarchies naturally correspond to the inductive definition of PEGs. The library extends on the subject of PEGs with new expression types, actions that can be attached to grammar rules, and mechanisms to ensure helpful diagnostics in case of parsing errors. PEGs are superficially similar to Context-Free Grammars (CFGs).
siwapp is a Web application meant to help manage and create invoices in a simple, straightforward way. It can manage invoices with different serial numbers (as rectification invoices), provide printable PDF versions of the invoices with a professional look & feel, save drafts of your invoices and continue editing them later, and automatically generate invoices on a periodic basis.
pymds is a simple, authoritative-only DNS server that has a simple module system for customizing how name resolution happens. The main motivation for starting this project was to create a simple system for building smarter DNS servers, capable of geography awareness, geographic load balancing, application aware load balancing, etc. Current modules implement standard behavior of using a file based DB to answer queries and to provide simple round-robin load-balancing across several servers by altering the order that IP addresses are returned.
delegate.c implements an abstract function pointer by capturing a user-specified callback signature -- delegate() -- and exposing it through a simple interface -- invoke(). It provides something loosely approximating lambda expressions; or even more analogous, C# delegates. It includes a wrapper to support libevent callbacks to functions not matching the required libevent callback signature.
Nagios 4 iPhone is a Nagios interface for the iPhone. It does not require any modifications on your Nagios servers. The server part of this software collects statistics on several Nagios servers, serves a few static files, and generates a JSON response. The client part handles the display of the data on the iPhone.
Winnow efficiently trains and operates any number of unique Bayesian (Naive Bayes) classifiers on large sets of content. It has very high performance and works with very small training and unbalanced training sets. It has been used to power an innovative Web feed reader that uses smart tags, which learn and find the content you want to see, from more sources than you can follow with traditional feed readers. It works particularly well with Ruby and Ruby on Rails.
