JSLint takes a JavaScript source and scans it. If it finds a problem, it returns a message describing the problem and an approximate location within the source. The problem is not necessarily a syntax error, although it often is. JSLint looks at some style conventions as well as structural problems. It does not prove that your program is correct. It just provides another set of eyes to help spot problems.

When I asked myself why people visit my sites, and the ones that I make for other people, the answer was always for the content. Content that is almost always written words and that means type.

That is why I'm now advocating to my clients (and to you), that where feasible, not to waste hours in time and a client's money on lengthy workarounds in an unnecessary attempt at cross-browser perfection. Instead, you and I should provide simple but effectively designed HTML elements. This means great typography for headings, paragraphs, quotations, lists, tables and forms and no styling of layout.

jQuery doesn't focus on things outside of the DOM. This is one of the reasons it is so easy to learn, but it also limits the ways it can help you write JavaScript. It's just not trying to be anything other than a solid programming system for the DOM. It doesn't address inheritance nor does it address the basic utilities of all the native types in the JavaScript language, but it doesn't need to. [...]

This is where MooTools is vastly different. Rather than focusing exclusively on the DOM (though, as I'll get into in a bit, it offers all the functionality that jQuery does but accomplishes this in a very different manner), MooTools takes into its scope the entire language. If jQuery makes the DOM your playground, MooTools aims to make JavaScript your playground, and this is one of the reasons why it's harder to learn.

The ubiquity of frustrating, unhelpful software interfaces has motivated decades of research into “Human-Computer Interaction.” In this paper, I suggest that the long-standing focus on “interaction” may be misguided. For a majority subset of software, called “information software,” I argue that interactivity is actually a curse for users and a crutch for designers, and users’ goals can be better satisfied through other means.

RPX provides a fully managed sign-in interface that is quick and easy to add to your website. It helps the user choose a sign-in provider, and remembers their decision next time they visit your site, for a one-click login experience. The interface is available either as a javascript popup, or as an IFrame embeded directly into your page.

OAuth is a simple way to publish and interact with protected data. It's also a safer and more secure way for people to give you access. We've kept it simple to save you time.

This guide is intended for a technical audience with focus on implementation. I dedicate one section to the end-user perspective which is something I expect many others will address with mockups, user interface designs, best practices guides, and of course working services. To make the most out of this guide, keep the specification handy as I will be referencing it, walking you through the spec and adding color where needed. This guide does not replace the specification nor can it be used alone for implementation as it is incomplete.

Adding Facebook Share to your website is easy. However, you can enhance how the shared item appears on Facebook by configuring how it gets previewed on a user's profile and when a user tries to share it. You do this with a combination of <link> and <meta> tags. Facebook Share passes along the URL of your page to our servers, which in turn looks up certain HTML tags within it. Those tags are used to display a preview of the page. In order to provide this preview, we always look for the title of the page, a summary of the main content and an image. If there's media content on the page, those media files are also important to identify.

With OpenGL, you can control computer-graphics technology to produce realistic pictures or ones that depart from reality in imaginative ways. This guide explains how to program with the OpenGL graphics system to deliver the visual effect you want.

Did you know that all websites that you visit can find out which fonts you have installed? It's also possible to find out if you have a range of programs installed. These include Adobe Reader, OpenOffice.org, Google Chrome and Microsoft Silverlight. Perhaps even which sites you have visited lately can be detected!

When you surf around the internet your browser leaves behind a trail of digital footprints. Websites can use these footprints to check your system. BrowserSpy.dk is a service where you can check just what information it's possible to gather from your system, just by visiting a website.
