The CSMS - Roslyn is the full CSMS display with the Project Management Tool plugin and metrics side done with Roslyn for C# and VB. This is a useful tool for small businesses or groups that wish to manage projects efficiently and without spending tons of money for a similar tool.

CSS-Inspiration is a living gallery of modern CSS effects and components that highlights what’s possible with pure CSS and minimal markup. The collection ranges from micro-interactions and loaders to 3D transforms, complex backgrounds, hover states, and text effects, each presented as a small, self-contained demo. Source code is front and center, encouraging developers to study, copy, and tweak snippets for their own projects. Many examples lean on contemporary features—custom properties, filters, blend modes, gradients, and keyframes—serving as both inspiration and a practical cookbook. Because each demo focuses on a single idea, it’s an effective way to learn new techniques without wading through a full framework. The project thrives on experimentation and community interest, making it a frequent reference for designers, front-end engineers, and educators who want visually striking yet lightweight solutions.

CSS Theme Change is a small utility for managing CSS theme toggling (such as light/dark mode) in web projects, designed to be lightweight, easy to integrate, and framework-agnostic. Instead of relying on heavy JavaScript frameworks or complex state management, it offers a simple API that listens to system preferences and UI interactions to swap theme classes or variables in real time. It can react to user toggles as well as automatically adapt to the user’s OS-level dark/light mode settings, helping developers build interfaces that feel modern and responsive without writing boilerplate theme code. Because it abstracts away cross-browser quirks and standardizes how CSS variables or classes are applied, it saves time and reduces bugs related to inconsistent theme behavior. It’s also modular and tiny in size, meaning it can be dropped into static sites, component libraries, or SPAs without significantly increasing bundle size.

CSS3 GitHub Buttons provides a set of GitHub-style buttons implemented with modern CSS, showcasing how to recreate familiar UI affordances without heavy images or scripts. The components focus on semantic HTML and CSS3 features like gradients, border-radius, and shadows to achieve a polished look. Because the styles are modular and predictable, they can be dropped into many sites with minimal adjustments. The code demonstrates how to handle hover, active, and disabled states in a way that feels native to GitHub’s aesthetic. It also highlights cross-browser considerations for older engines while keeping the footprint light. For designers and front-end developers, it serves as both a ready-to-use component set and a learning example of crafting classic UI patterns with pure CSS.

Coding regular emails is hard enough by itself. Making them responsive shouldn’t add to the headache. A few simple, but solid patterns are all that’s needed to optimize emails for small screens. It’s just a few responsive email patterns that go a long way. The code blocks are compartmentalized so they may be used, removed, combined, and nested to build an email. Each template contains code comments and has good support among popular email clients. Cerberus is a small collection layout patterns for HTML email. The code is meant to be edited, adapted, and built upon. The code is compartmentalized and annotated in an effort to explain what’s happening so you can add, edit, and remove code with some confidence. This has been tested in all “popular” email clients, but not every email client out there. Good for simple layouts such as transactional and single-column emails.

The demo of the new Android Design library. This is not an exhaustive sample, but shows some of the important features in the Design library. Cheesesquare Sample provides a collapsing toolbar, a Floating Action Button, features a View Anchoring option, a NavigationView option, and a Snackbar feature, as well. As a pre-requisite, users should already have Android SDK v22, Android Build Tools v22.0.1, as well as Android Support Repository r16 (for v22.2.1), in order to work properly. Cheesesquare Sample is licensed to the Apache Software Foundation.

ClassReach is a utility to identify unused Java classes and methods. Once identified, such things can be removed from the code, hopefully simplifying the system.

CodaServer is a database that makes building business applications easy. It uses a SQL-like language that lets you describe your workflow and business processes, and uses this information to enforce your business rules and guarantee data integrity.

Code Appearance is a small application that beautify the code before you put it on a forum or a website. What it does? It adds color to the code, like the syntax highlighting of your favorite IDE. The syntax files are easily customizable. How it works? You choose a syntax file, these files can be downloaded or made by you, and write/copy/open your code and click on execute. A new window will pop up with the result. On this new window, you will be able to save or copy the code to the clipboard.
