PyramiDOM: Spectrum DOM Analyzer

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…

WPS: PostScript and PDF interpreter for HTML 5 canvas

Category: Canvas, Showcase

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: javascript < view plain text > /n 10 def /w 25 def   0 0 n w mul dup .gbox   Read the rest…

Chroma Hash: Interesting visualization of your password

Category: CSS, jQuery

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…

Text rotation for all

Category: CSS, Tip

Jonathan Snook has posted a nice nugget on text rotation with CSS that takes a nice bit of markup like this: HTML4 < view plain text > <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: css < view plain text > -webkit-transform: rotate(-90deg); Read the rest…

Developer evangelism handbook released

Category: Examples, Presentation, Workshop

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.

Dynamic script generation and memory leaks

Category: JSON, Performance

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: javascript < view plain text > 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…

To use, just include css-gradients-via-canvas.js (12KB) anywhere on the page (see examples below). Unlike Read the rest…

Multiple font weights via CSS 3 and more font fun

Category: CSS

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 css < view plain text Read the rest…

A detailed look at how tracing, and TraceMonkey works

Category: JavaScript, Performance
