Adaptive Images detects your visitor’s screen size and automatically creates, caches, and delivers device appropriate re-scaled versions of your web page’s embeded HTML images. No mark-up changes needed. It is intended for use with Responsive Designs and to be combined with Fluid Image techniques.

Adapt.js is a lightweight (831 bytes minified) JavaScript file that determines which CSS file to load before the browser renders a page. If the browser tilts or resizes, Adapt.js simply checks its width, and serves only the CSS that is needed, when it is needed. A potential drawback of Adapt.js is the possibility of a brief flash of unstyled content as a new stylesheet is being fetched (think of it as “Ajax” for CSS). I have done my best to mitigate this by keeping CSS files small (3 KB). It is worth noting this is a proposed, not prescribed, approach to a problem with multiple solutions. Other methods include: Build a separate site for mobile. Or, use media queries to adjust layout, with a polyfill for older browser support, and conditional Internet Explorer comments for Windows phones. Also a factor is how to handle multiple image resolutions without adding file size. Filament Group is advocating context aware image sizing.

It’s a JavaScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each files into small chunks; whenever the upload of a chunk fails, uploading is retried until the procedure completes. This allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause and resume uploads without loosing state. Resumable.js relies on the HTML5 File API and the ability to chunks files into smaller pieces. Currently, this means that support is limited to Firefox 4 and Chrome 11 .

The main focus of CamanJS is manipulating images using the HTML5 canvas and Javascript. It’s a combination of a simple-to-use interface with advanced and efficient image/canvas editing techniques. It is also completely library independent and can be safely used next to jQuery, YUI, Scriptaculous, MooTools, etc. CamanJS is very easy to extend with new filters and plugins, and it comes with a wide array of image editing functionality, which is only growing as the community makes more plugins. It has a powerful layering system, much like the one present in Photoshop and GIMP, that makes the sky the limit for your creativity.

CSSrefresh is a small, unobstructive javascript file that monitors the CSS-files included in your webpage. As soon as you save a CSS-file, the changes are directly implemented, without having to refresh your browser.

PHP Bug Lost is a one-file script PHP debug and monitoring console. Include it in your script and: send log messages, view SQL queries (sends an email to the admin if there’s an error), measure times and memory usage (sends emails for long loading times or excessive memory usage), see all the vars in your scripts and view all your AJAX queries (send params and responses). PHP Bug Lost can run in a console or in a monitor. Use it like a console for developing sites to help you in your daily work, and as a monitor for production sites for controlling errors, load times and memory usage. Find those bugs! PHP Bug Lost is free, open source. At the moment I’m experimenting with it, trying new features, thinking what is good and what not… etc. let me know if you found any bug or see a better way for do anything.

Like a lot of developers, we start every HTML project with the same set of HTML and CSS files. We’ve been using these files for a long time and have progressively added bits and pieces to them as our own personal best practices have evolved. Now that modern browsers are starting to support some of the really useful parts of HTML5 and CSS3, it’s time for our best practices to catch up, and we thought we’d put our files out there for everyone to use. By no means do we see this as the One True Way to start every project, but we think it’s a good starting place that anyone can make their own.
