Adobe's service that provides a nice array of browser screenshots of any URL entered, significantly easing cross-browser tests.

Gitbox »

"a Mac OS X graphical interface for Git version control system. In a single window you see branches, history and working directory status."

jQuery.Html5form »

HTML5 includes form validation as part of the spec, so once it's fully supported we won't need to use JavaScript to validate form input. Sadly, this is only supported by Webkit browsers at the moment (Safari & Chrome). This plugin addresses the gap for the other major browsers with a single line of code.

PaintbrushJS »

"A lightweight browser-based image processing library".

JavaScript's come a long way. This library provides a wealth of image manipulation capabilities, including tints, blur, noise, sepia and grayscale - all handled by the browser. What a sweet way to ensure you don't have to reprocess your images the next time you redesign your site.

Pictos »

Using a font instead of images for icons is an interesting concept, which ensures that the icons are infinitely scalable and that the presentation can be easily changed on the fly without any extra page weight (even more so with CSS3).

I am curious where the tipping point lies in terms of page weight and render speed - 3 icons used, five...15? Either way, this is a really good start down an innovative path.

HTML5 Boilerplate »

As noted on the site, this is "the professional badass's base HTML/CSS/JS template for a fast, robust and future-proof site" While I likely won't use this whole, there are some very interesting pieces to this worth using, especially in the style sheet and .htaccess files. I'll likely appropriate many of the concepts for my work.

This is an outstanding contribution to the Web development community by Paul Irish and Divya Manian as well as all of the people whose work they built upon.

Compass »

"Compass is a stylesheet authoring framework that makes your stylesheets and markup easier to build and maintain. With compass, you write your stylesheets in Sass instead of CSS. Using the power of Sass Mixins and the Compass community, you can apply battle-tested styles from frameworks like Blueprint to your stylesheets instead of your markup."

Ruby must be on the system in order for the style sheets to be compiled, but the output doesn't require it.

Style Guides Using Sass @extend »

via @pengwynn. This is a smart use of Sass to define a separate style guide file for key presentation elements like fonts and colors that the designer can easily modify, while ensuring that the main style sheet can inherit all of those values.

This warms my front-end developer heart as I'm not fond of breaking up a site into separate style sheets for colors, spacing, fonts and the like as it becomes unmanageable or very cumbersome as everyone has to be aware of which files reference any given element, and should a significant change need to be made to the structure of the markup, it must be reflect throughout the site.

jQuery each2 plugin vs jQuery core .each method »

via @getify. A jQuery plugin optimized to handle the use of $(this) inside an .each loop.

The HTML5 test »

This site provides "an indication of how well your browser supports the upcoming HTML5 standard and related specifications."

How FuncUnit works »

An open source JavaScript web application testing framework that combines Selenium, jQuery, QUnit and Envjs and your debugger of choice (such as Firebug). Looks interesting.

html5shiv »

I didn't realize Google hosts the HTML 5 Shiv in addition to the other JavaScript frameworks that it's kind enough to provide the community. Nice!

If you want to use HTML 5, the shiv is pretty well a requirement as Internet Explorer (up to and including IE 8) doesn't support the new elements in the spec. Plus it's easy to implement and will only be downloaded by the browsers that need it.

Web Performant WordPress »

Dave Rupert provides an excellent breakdown of how to speed up your WordPress-powered site. There's no excuse to not spend the time implementing these changes. Even if you're like me, and have already done a lot of the work, I'm willing to bet there's a step or two that will make your site even better. For me, it's the super-duper-easy cut-and-paste improvements to the htacess file to enable gzip and browser caching.
