tobeytailor’s gordon. Another Flash runtime in pure JavaScript project, released back in January. Not quite as advanced as Smokescreen yet (it doesn’t have an audio implementation) but already available as open source under an MIT license. # 29th May 2010, 11:57 am
Smokescreen demo: a Flash player in JavaScript. Chris Smoak’s Smokescreen, “a Flash player written in JavaScript”, is an incredible piece of work. It runs entirely in the browser, reads in SWF binaries, unzips them (in native JS), extracts images and embedded audio and turns them in to base64 encoded data:uris, then stitches the vector graphics back together as animated SVG. Open up the Chrome Web Inspector while the demo is running and you can see the SVG changing in real time. Smokescreen even implements its own ActionScript bytecode interpreter. It’s stated intention is to allow Flash banner ads to execute on the iPad and iPhone, but there are plenty of other interesting applications (such as news site infographics). The company behind it have announced plans to open source it in the near future. My one concern is performance—the library is 175 KB and over 8,000 lines of JavaScript which might cause problems on low powered mobile devices. # 29th May 2010, 11:32 am
Busting frame busting: a study of clickjacking vulnerabilities at popular sites (via) Fascinating and highly readable security paper from the Stanford Web Security Research group. Clickjacking can be mitigated using framebusting techniques, but it turns out that almost all of those techniques can be broken in various ways. Fun examples include double-nesting iframes so that the framebusting script overwrites the top-level frame rather than the whole window, and a devious attack against the IE and Chrome XSS filters which tricks them in to deleting the framebusting JavaScript by reflecting portions of it in the framed page’s URL. The authors suggest a new framebusting snippet that should be more effective, but sadly it relies on blanking out the whole page in CSS and making it visible again in JavaScript, making it inaccessible to browsers with JavaScript disabled. # 24th May 2010, 11:40 am
jed’s fab. Spectacular web framework for Node.js which, despite using nothing but regular JavaScript, has syntax that is easily confused with Lisp. General consensus at work is that truly understanding how this works is a crucial step on the path to JavaScript enlightenment. # 18th May 2010, 6:50 pm
Understanding node.js. A king providing orders to his army of servants is a much better analogy than my hyperactive squid. # 18th May 2010, 6:44 pm
The All-In-One Almost-Alphabetical No-Bullshit Guide to Detecting Everything. Appendix A of Dive Into HTML5. # 14th May 2010, 2:17 pm
Music Notation with HTML5 Canvas. A pretty decent effort at rendering musical notation using JavaScript and the canvas element. # 12th May 2010, 8:53 am
Realtime Election Tweets. Jay Caines-Gooby’s realtime election tweet service, using Node.js, nginx and WebSocket with a Flash fallback. # 6th May 2010, 9:20 pm
premasagar’s sandie. “Sandie is a simple method for loading external JavaScript files into a page without affecting the global scope, to avoid collisions between conflicting scripts”—works by loading the script in an invisible iframe (hence a new global scope) and then passing a reference to a callback function in the parent page. # 6th May 2010, 8:37 pm
Pure CSS3 Spiderman Cartoon w/ jQuery and HTML5. Great demo, though calling -webkit-animation HTML5 (or even CSS3) is a bit of a stretch... # 4th May 2010, 7:27 pm
