SDF is a language for defining syntax. It provides for an unprecedented level of conciseness in syntax definitions. First, syntax can be defined in modules. Second, lexical and context-free syntax are integrated in a single formalism in which the complete syntax of a language can be defined. Third, SDF includes declarative disambiguation constructs. Therefore, there is no need to introduce non-terminals to deal with ambiguities in a language. Some useful places to start: An overview of the unique features of SDF Pointers to SDF documentation Download the implementation of SDF Research papers about SDF Find SDF grammars for many languages here Subscribe to the mailing list for announcements and discussions.

Operational familiarity – BIND is single software system that supports both authoritative and recursive functions. While it is recommended to run authoritative and recursive functions on separate servers, you can use the same software for both functions. In an enterprise that might not need a lot of DNS servers, it can simplify operations to only have to use one system. BIND is the only DNS software that can be either authoritative or a full recursive resolver.

Agda is a dependently typed functional programming language. It has inductive families, i.e., data types which depend on values, such as the type of vectors of a given length. It also has parametrised modules, mixfix operators, Unicode characters, and an interactive Emacs interface which can assist the programmer in writing the program.

Located here is a basic decoder for Apple Lossless Audio Codec files (ALAC). ALAC is a proprietary lossless audio compression scheme. Apple never released any documents on the format. What I provide here is a C implementation of a decoder, written from reverse engineering the file format. It turns out that most of the algorithms in the codec are fairly well known. ALAC uses an adaptive FIR prediction algorithm and stores the error values using a modified rice or golumb algorithm. Further details are in alac.c.
