Canvas LMS is a full-featured learning management system designed for K–12, higher-ed, and professional training, with a strong emphasis on usability and openness. Instructors build courses from modular content—pages, assignments, discussions, quizzes—and organize them into learning paths with prerequisites and due dates. Rich grading tools like SpeedGrader streamline assessment with rubrics, inline annotations, and audio/video feedback, while the gradebook supports weighting, outcomes, and late/missing policies. A robust API, standards like LTI/IMS Common Cartridge, and SIS integrations make it straightforward to connect Canvas with publisher content, analytics tools, proctoring, and institutional systems. Role-based permissions, accommodations, and accessibility features support diverse learners at scale, and mobile apps keep students engaged on the go.

*** Bridge Designer has been replaced with the web app ASCE Bridge Designer, Cloud Edition (Google this term to find the app)! Binaries posted here will go away on 1 July 2026. The source repo will remain. The contest is no longer active. *** 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.

Welcome to the second edition of the Pro Git book. The entire Pro Git book, written by Scott Chacon and Ben Straub and published by Apress, is available here.

What is “version control”, and why should you care? Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. For the examples in this book, you will use software source code as the files being version controlled, though in reality you can do this with nearly any type of file on a computer. If you are a graphic or web designer and want to keep every version of an image or layout (which you would most certainly want to), a Version Control System (VCS) is a very wise thing to use.

analyze is a collection of in-depth source code analyses of popular open source projects, primarily focused on programming languages, compilers, operating systems, and distributed systems. Maintained as a knowledge repository, it contains detailed write-ups that explain the internal mechanisms of complex software systems. The project is designed for developers and researchers who want to deepen their understanding of how widely used technologies are built and maintained. Each analysis breaks down design choices, implementation details, and architectural patterns, making difficult topics more approachable. The repository emphasizes clarity and structured explanations, serving both as a study resource and a reference for engineers exploring system internals. By gathering analyses of diverse projects in one place, analyze helps learners and practitioners bridge the gap between theory and large-scale production code.

Magic of CSS is an open source educational project by Adam Schwartz that explores advanced CSS concepts through practical lessons. It is structured as a series of chapters that cover topics like the box model, layouts, positioning, typography, and animations. The repository is designed to go beyond basic CSS tutorials, teaching how to harness the language for complex, responsive, and visually appealing designs. Each lesson is supported by examples and code that demonstrate real-world use cases. The project emphasizes both the technical and creative potential of CSS, showing how small details can greatly improve user experience. It has become a valuable reference for developers aiming to deepen their front-end skills.

Main goals: * Prepare operating system based on Linux kernel and free software for use at home from scratch by building sources. Binary packages/images are also available. * Each package is installed in separate directory, so you can use different versions of applications and libraries by design. * There is only one user 'kanapi' with root permissions, so you don't have to login, remember passwords, etc. * Simple configuration * Automatic compilation.

VirtualX is an open source online examination system and can be used across organization types such as Colleges/Universities, Schools etc. This tool allows Administrators, Examiners, and Question Setters to add/edit/delete questions and schedule tests, quizzes, exams and generate reports.

This is a modified version of the CRC algorithms by Lammert Bies. It supports more algorithms and has been ported to several languages. It's also useful for learning how to do hexadecimal calculations and bitwise operations in various programming languages. Disclaimer: These test programs demonstrate the calculation of CRC. I made these translation with a basic knowledge of each language. They may or may not be appropriately formatted / secured / robustified / idiot proofed or any similar programming issues.
