A toolkit for building rich-text editors on the web.

An ideal content editor produces structured, semantically meaningful documents, but does so in a way that is easy for users to understand. ProseMirror tries to bridge the gap between Markdown text editing and classical WYSIWYG editors.

It does this by implementing a WYSIWYG-style editing interface for documents more constrained and structured than plain HTML. You can customize the shape and structure of the documents your editor creates, and...

Hidden messages in JavaScript property names
Recently I came across this tweet by @FakeUnicode. It included a JavaScript snippet which looked pretty harmless but resulted in a hidden message being alerted. I took me a while to understand what's going on so I thought that documenting the steps I took could be interesting to someone.

Prepack · Partial evaluator for JavaScript
Prepack is a tool that optimizes JavaScript source code: Computations that can be done at compile-time instead of run-time get eliminated. Prepack replaces the global code of a JavaScript bundle with equivalent code that is a simple sequence of assignments. This gets rid of most intermediate computations and object allocations.

Generating fantasy maps
I wanted to make maps that look like something you'd find at the back of one of the cheap paperback fantasy novels of my youth. I always had a fascination with these imagined worlds, which were often much more interesting than whatever luke-warm sub-Tolkien tale they were attached to.

JointJS - the HTML 5 JavaScript diagramming library.
JointJS is a modern HTML 5 JavaScript library for visualization and interaction with diagrams and graphs. It can be used to create either static diagrams or, and more importantly, fully interactive diagramming tools such as workflow editors, process management tools, IVR systems, API integrators, presentational applications and more. JointJS makes it easy to create visual tools of various kinds.

The event-driven nature together with MVC architecture of JointJS makes it easy to plug-in any backend technology.

While JointJS core library is great for small open source projects, we recommend you to check out Rappid, the complete HTML 5 diagramming UI framework that is built on the strong foundation of JointJS. Rappid widely extends JointJS with about 40 UI widgets and other components that extremelly speed up the development of diagramming applications.

Genetic algorithms, Mona Lisa and JavaScript + Canvas - Nihilogic
There was an interesting article about using genetic algorithms to "evolve" images. Roger Alsing had made a small program and put it to the test by letting it make a very good approximation of the Mona Lisa with 50 layered, semi-transparent polygons. I figured I'd try to do something similar with JavaScript and Canvas.

Spidering the web with CasperJS | Blog | Plan Zero
In the past I've used the excellent PhantomJS headless webkit browser for automation, but writing complex navigation scenarios can be a bit long-winded. Enter CasperJS. Built on top of PhantomJS, it simplifies the process and provides some nice syntactic sugar to boot.

The spider I wrote grabs the first page, finds all of the links, then by pushing each URL onto a stack and shifting new URLs from the bottom, follows each link in the order in which it was found.

Project Windstorm. Terrain demo in webgl
When I tried to think of a project suitable for learning JavaScript, a terrain flyover demo came to mind. I've worked with terrain rendering in OpenGL before and using WebGL inside a Canvas element kept me pretty close to my comfort zone. Somehow, I quickly found myself also building a WebGL GUI to act as a debugging aid at first, a way to demonstrate and monitor the behavior of the terrain algorithms later.

Using the Console - Chrome Developer Tools — Google Developers
The JavaScript Console provides two primary functions for developers testing web pages and applications:A place to log diagnostic information using methods provided by the Console API, such as console.log(), or console.profile() and a shell prompt where you can enter commands and interact with the document and the Chrome DevTools. You can evaluate expressions directly in the Console, and can also use the methods provided by the Command Line API, such as $() command for selecting elements, or profile() to start the CPU profiler.

Web Cryptography API
This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Key storage is provided for both temporary and permanent keys. Access to keying material is contingent on the same origin policy. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.
