Andrea Giammarchi has created PyramiDOM a “Spectrum DOM Analyzer”. When I first saw it, and read “Spectrum” I thought I was looking at an old 48k video game, but in fact it is showing you info on the DOM: The generated spectrum will contain every single nodeType 1 present in the document and will show Read the rest…
It would be a pretty cool hack to implement a PostScript/PDF interpreter in JavaScript wouldn’t it? That is exactly what has been done with WPS. The code takes PS and really groks it so: < View plain text > javascript /n 10 def /w 25 def 0 0 n w mul dup .gbox Read the rest…

Nicholas Zakas thinks he has the best way to load JavaScript. Steve Souders has a bunch of best practices, and it seems that there is definitely nuance that makes advice very much tailored to your circumstance. Nicholas though, has an opinion: I’ve come to the conclusion that there’s just one best practice for loading JavaScript Read the rest…

The doctor is in, and this time the specialist is Mark Boas who walks us through HTML5 Audio in various browsers and how to get audio working on the various implementations that are in the wild today.

Matt Thompson has created a fun little jQuery plugin called Chroma-Hash that “dynamically visualizes secure text-field values using ambient color bars”: Password entry can be frustrating, especially with long or difficult passwords. On a webpage, secure fields obscure your input with •’s, so others can’t read it. Unfortunately, neither can you—you can’t tell if you Read the rest…
Jonathan Snook has posted a nice nugget on text rotation with CSS that takes a nice bit of markup like this: < View plain text > HTML <div class="example-date"> <span class="day">31</span> <span class="month">July</span> <span class="year">2009</span> </div> and converts it to: all via the CSS: < View plain text > css -webkit-transform: rotate(-90deg); Read the rest…

As developers, it can be hard to get your voice heard in a company. Whilst our products depend on developers building them the right way, other people seem to call the shots about where they are going. This becomes disastrous when a company tries to reach developers with their product. Normal marketing and PR stunts Read the rest…

An interesting piece by Neil Fraser shows that using JSON-P with generated script nodes can be quite a memory leak. Normally you’d add information returned from an API in JSON-P with a generated script node: < View plain text > javascript script = document.createElement(‘script’); script.src = ‘http://example.com/cgi-bin/jsonp?q=What+is+the+meaning+of+life%3F’; script.id = ‘JSONP’; script.type = Read the rest…

Weston Ruter has created a very cool library that enables CSS gradients on non-WebKit browsers (at least, a subset). Incredibly cool: CSS Gradients via Canvas provides a subset of WebKit’s CSS Gradients proposal for browsers that implement the HTML5 canvas element. To use, just include css-gradients-via-canvas.js (12KB) anywhere on the page (see examples below). Unlike Read the rest…

Over in Geneva, they have posted on coupling PHP and Workers. They build on the great intro from John and tweak it to use simple PHP on the backend to do things such as making sure that your favourite library has been loaded into each Worker, so you can use it in your script. < Read the rest…

Ilia Draznin has been using CSS3 font face to fake font weights: The way @font-face works is that whatever font attributes you specify for a @font-face rule, they don’t determine how the font looks but rather when it’s gonna get used. For example if you have the following two rules < View plain text > Read the rest…

The Jetpack project is still a young ‘un from Mozilla Labs (disclaimer: I work for labs!) but they are moving swiftly indeed, and each new release has a wicked cool new API that let’s you do something you couldn’t easily do before. With the Jetpack 0.4 release we see two cool APIs: Audio Recording API Read the rest…

David Mandelin has generously detailed an overview of tracing and TraceMonkey in particular. He starts out by explaining the problem at hand: making a dynamic language such as JavaScript fast is hard. How do you get type info in dynamic type land? Our goal in TraceMonkey is to compile type-specialized code. To do that, TraceMonkey Read the rest…
