**Unfortunately, the Bridge Contest is no longer operational. We hope the code base will be of use to others with similar projects in mind.** A national virtual bridge engineering contest with prizes for middle and high school kids, grades 6 to 12, but anyone can enter for fun. Based on the award-wining Bridge Designer client software, now open source through this project. Web site infrastructure supports worldwide participation in qualifying and semifinal rounds with a tiny administrative staff. The new Rails back end is a RubyMine project. Thanks to JetBrains for this mega development environment!

The DkIT Bridge Designer will provide you with a realistic introduction to engineering through an authentic, hands-on design experience. This software provides you with the tools to model, test, and optimize a steel highway bridge, based on realistic specifications, constraints, and performance criteria. Supported by Dundalk Insititute of Technology and All-Island Funds, this is a virtual bridge designer that allows kids of all ages learn about engineering and compete with their classmates!

QDBM is a library of routines for managing a database. It is developed referring to GDBM for the purpose of the following three points: higher processing speed, smaller size of a database file, and simpler API..

This is a C library to check the validity of German and Austrian Bank Account Numbers. All currently defined test methods by Deutsche Bundesbank (Dec 2017: 00 to E4) are implemented. Modules for AWK, Perl, PHP, Python, Ruby, C#.net and VB.net are included too. The package includes also an IBAN converter to generate (german) IBANs and BICs from account data. All currently defined IBAN rules by Deutsche Bundesbank are implemented (Dec 2017: 57 rules) and tested against independent solutions.

The Art of Programming (Second Edition) is a curated collection of programming problems and solutions originally derived from the Microsoft 100 Interview Questions blog series, later refined into a long-running tutorial and ultimately a published book. Created by July, the series began in 2010 and has since evolved into an in-depth exploration of algorithmic thinking, data structures, and coding interview preparation. The repository brings together 42 classic programming problems from the original series, enhanced with detailed explanations, formula derivations, and optimized solutions. In July 2023, work on the second edition was announced, which expands the project with updated content, new problems inspired by recent big-tech interviews, and introductions to modern machine learning techniques such as XGBoost, CNNs, RNNs, and LSTMs. This collection serves both as a historical record of algorithm problem-solving and as a living resource for programmers preparing for interviews.
