Nested is a jQuery plugin which allows you to create multi-column, dynamic grid layouts. Unlike other libraries and jQuery plugins similar to Nested, this is (as far I as I’ve know) the first script out there that allows you a complete gap-free layout. How is this done? Nested does three things. It creates a matrix of all elements and creates a multi column grid, similar to other libraries and scripts out there. Then it scans the maxtric for gaps and tries to fill them by reordering the elements. This is exactly how I’ve seen other newer libraries, scripts and modifications behave but if you stop here, the result will sometime leave unwanted gaps as well. That is why I added the last step, an option to resize any element at the bottom of the grid that is bigger (or smaller if you prefer) than the gap to make the grid completely gap-free.

HTML5 Canvas Heatmap Library. 🔥 JavaScript Library for HTML5 canvas based heatmaps
heatmap.js is a JavaScript library that can be used to generate web heatmaps with the html5canvas element based on your data. Heatmap instances contain a store in order to colorize the heatmap based on relative data, which means if you're adding only a single datapoint to the store it will be displayed as the hottest(red) spot, then adding another point with a higher count, it will dynamically recalculate. The heatmaps are fully customizable.
Guard skills for coding agents, quality gates that catch AI-generated failure modes in code, tests, and docs.
Focused guard skills for coding agents: second-pass quality gates that catch the systematic failure modes of AI-generated code, tests, and docs before they ship.
Best use: let your agent do the work, then invoke the relevant guard on the diff before you present, commit, or merge it. These skills can guide writing when you explicitly ask for that, but they are strongest as reactive review passes.
