Barcode Writer in Pure Postscript implements the printing of many barcode formats entirely within PostScript, so that the process of converting the input string into the printed output is performed by the printer or print system. The project supports all major barcode formats including: EAN-13 (JAN-13), EAN-8 (JAN-8), UPC-A, UPC-E, EAN-5 & EAN-2 (EAN/UPC add-ons), ISBN (including legacy ISBN), ISMN (including legacy ISMN), ISSN, Code 128 (A, B & C), GS1-128, SSCC-18 (EAN-18, NVE), EAN-14, Code 39, Code 39 Extended, Code 93, Code 93 Extended, Code 32 (Italian Pharmacode), Pharmazentralnummer (PZN), Interleaved 2 of 5, ITF-14 (UPC SCS), GS1 DataBar (Omnidirectional, Stacked, Stacked Omnidirectional, Limited, Expanded, Expanded Stacked), Code 2 of 5 (Industrial, IATA, Matrix, Datalogic & COOP), Code 11 (USD-8), BC412, Codabar (NW-7), Pharmacode (including two-track), MSI, Plessey, Telepen, Channel Code, PosiCode, PDF417, Data Matrix (ECC200), QR Code (including Micro QR Code), and more.
Bibulous is a drop-in BibTeX replacement based on style templates. It provides all of the functionality of BibTeX, while adding the ability to work with large-scale databases, multilingual data, localized sorting, and a lot more. Its outstanding feature is that users can define new bibliographic styles in a matter of minutes without mastering the details of any user guide and without needing to understand the underlying code. This is possible through the use of style templates, which are ideal structures for defining the format of a bibliography.
Bike is a Web application framework that can make feature-rich applications using HTML files only. You need no database setup (by default), no scheme definition, and no command-line voodoo. Just put a good old HTML file under skin/, and your new app is already running. Bike is front-ended by Rack, back-ended by Sequel.
Binary Puzzle Solver in Ruby is an automated solver for Binary Puzzles (a kind of logic game) featured on http://www.binarypuzzle.com/. The solver contains an API and a commandline program and explains why it thinks the player should place a 0 or a 1 in the box. Although it contains only a subset of the moves the authors could think of and does not use backtracking, it was able to solve all the puzzles from binarypuzzle.com which the authors tried.
BitMagic is C++ library designed and developed to implement efficient, platform-independent bitsets. It features several types of on-the-fly adaptive compression, dynamic range of addressable space of 2^32-1 bits, efficient memory management, serialization in a platform-independent, compact format suitable for storing in files and databases, performance tuning for 32-bit and 64-bit systems, and optimization for Intel SSE2 128-bit integer SIMD.
