Qhub is a simple way to create a Q&A website. While other Q&A websites are great for information sharing and communities, Qhub offers a more targeted community managed by the people that are interested in that particular subject area.

Each group is set up and started by an owner. Friends, colleagues, club members and more are invited to join and the questions can begin. Qhub offers the ability to customize each site. There is full management of your site, its members and content. It also offers the ability to use your own domain name.

If someone asking you a question and you have the answer, why not open up that knowledge to the web community for their and your benefit?

New York Times online had an article which showed a road in Brooklyn that had been reconstructed to make it safer and more pleasing to the eye. To show the difference in the reconstruction project, they showed a before and after picture using Flash that let the visitor drag a slider over the images, which were sandwiched with one on top of the other, so that you could easily see how dramatic the changes were.

CatchMyFame found this very useful and immediately created Before/After jQuery Plugin for the same purpose. The possibilities for this plugin are endless. Doctors can have before and after images of patients, Photoshop users can show the before and after differences between images, remodelers can show the before and after images of projects and on and on. This plugin weighs in at only 7K and can be used multiple times on a page.

Highcharts JS is a charting library written in pure JavaScript, offering an easy way of adding interactive charts to your web site or web application. Highcharts JS currently supports line, spline, area, areaspline, column, bar, pie and scatter chart types.

It works in all modern browsers including the iPhone and Internet Explorer from version 6. Setting the Highcharts configuration options requires no special programming skills. The options are given in a JavaScript object notation structure, which is basically a set of keys and values connected by colons, separated by commas and grouped by curly brackets.

On hovering the chart, Highcharts JS can display a tooltip text with information on each point and series. By zooming in on a chart you can examine an especially interesting part of the data more closely. Zooming can be in the X or Y dimension, or both. Highcharts is licensed under a Creative Commons Attribution-NonCommercial 3.0 License.

Because web type renders differently with only subtle CSS adjustments, seeing it exercised in a variety of ways can help web designers typeset – and also help them decide which typefaces to purchase for their projects.

Therefore, Tim Brown has designed Web Font Specimen, which presents real web type in real web context, and released it under a Creative Commons license for the betterment of typographic style and practice.

The Any+Time JavaScript Library includes an easy-to-use, easy-to-customize calendar widget (date and/or time picker) and a powerful Date/String parse/format utility. ATWidget is the AJAX-capable JavaScript GUI component. It is easy to add to a page and even easier to use! Unlike most date/time selection tools, nearly every field in an ATWidget control can be chosen with a single mouse click.

The ATWidget date/time control is attached to any input (text) field with a single line of JavaScript code. It can be placed as a popup or inline. The appearance of the ATWidget calendar tool can be customized by modifying or supplementing the included CSS stylesheet. All labels, as well as month, weekday and era names and abbreviations, are also easy to change.
