S3QL is a file system that stores all its data online. It supports Amazon S3, Google Storage, and OpenStack and effectively provides you with a hard disk of dynamic, infinite capacity that can be accessed from any computer with Internet access. S3QL provides a standard, full featured Unix file system that is conceptually indistinguishable from any local file system. Additional features include compression, encryption, data de-duplication, immutable trees, and snapshotting, which make it especially suitable for online backup and archiving. The design favors simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection, error handling, and extensive automated test cases are provided.
wview is an application that controls a supported weather station to retrieve archive records and current conditions. Archive records may optionally be stored in a relational database (MySQL or PostgreSQL). At a user-defined interval, wview will use the archive history and current conditions to generate weather images (buckets and graphs) and Web pages based on configurable HTML templates. It supports serial and USB data loggers, as well as connectivity with a terminal server or serial server via TCP sockets.
aime is a simple, C-like programming language and an interpreter, both designed to be embeddable in applications. The language is straightforward, trivial, and direct. Its syntax is simpler than that of C, while still providing for full object management, higher order functions, and references. The interpreter is secure and expressive, allowing comprehensive control over program execution and providing powerful methods of application integration.
SHTns is a high-performance Spherical Harmonic Transform library. It was designed for numerical simulation (fluid flows, mhd, etc.) in spherical geometries, but can be used for any kind of problem involving scalar or vector spherical harmonics. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, and flexible truncation and normalization. A Python interface is included.
CUPS is a standards-based printing system for Mac OS X and other Unix-like operating systems. It provides the System V and Berkeley command line interfaces, and uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality. CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real world printing.
