Software development: Glossary 3-tier application a program that is organized into three major parts: the workstation or presentation interface; the business logic; and the database and related programming. Each of these is distributed to one or more separate places on a network. agile software development calls for keeping code simple, testing often, and delivering small, functional bits of the application as soon as they're ready. Amdahl's law stipulates that, in a program with parallel processing, a relatively few instructions that have to be performed in sequence will have a limiting factor on program speedup such that adding more processors may not make the program run faster. amelioration pattern a design pattern that describes how to go from a bad solution to a better one. antipattern a frequently used, but largely ineffective solution to a problem. API (application programming interface) application integration application program aspect-oriented programming (AOP) best practice bug a coding error in a computer program.

The Latest Updates to jQuery Mobile Not too long ago, the jQuery team released jQuery Mobile 1.2. This new release has some fantastic changes! In this article, we're going to review some of the new widgets available to developers, take a look at changes made to existing widgets, and glance over a few impactful enhancements that could affect your jQuery Mobile application. Firstly, we'll need to download the bits and bytes. Additionally, now might be a good time to quickly discuss the Download Builder that the jQuery Mobile team is building. Widgets The beating heart of any jQuery Mobile application are its widgets. Popups A popup modal is a small section of the page that overlays other parts of the page. A quick note, for the sake of brevity: all of the code samples below will use the following boilerplate HTML. Adding a popup to a page in your application is a two-step process. Second, you need the content to be displayed. What you'll see on the page should look something similar to this: Tooltips Menus And the results: Forms
Avoiding common HTML5 mistakes Between curating sites for the HTML5 gallery and answering readers’ questions here at HTML5 Doctor, I see a host of HTML5 sites and their underlying markup. In this post, I’ll show you some of the mistakes and poor markup practices I often see and explain how to avoid them. Don’t use section as a wrapper for styling One of the most common problems I see in people’s markup is the arbitrary replacement of <div>s with HTML5 sectioning elements — specifically, replacing wrapper <div>s (used for styling) with <section>s. In XHTML or HTML4, I would see something like this: <! Now, I’m instead seeing this: <! Frankly, that’s just wrong: <section> is not a wrapper. With that in mind, here’s the correct way to mark up the above example using HTML5 and a couple of ARIA roles. <body> <header> <h1>My super duper page</h1> <! If you’re not quite sure which element to use, then I suggest you refer to our HTML5 sectioning content element flowchart to guide you along your way. Ah, <figure>. <! Summary
HTML5 HTML5 is a markup language used for structuring and presenting content for the World Wide Web and a core technology of the Internet. It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML 4 as of 1997)[2] and, as of December 2012[update], is a candidate recommendation of the World Wide Web Consortium (W3C).[3] Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.[2] History[edit] The Web Hypertext Application Technology Working Group (WHATWG) began work on the new standard in 2004. While HTML5 is often compared to Flash, the two technologies are very different.

Dive Into HTML5 Kinect for Windows Blog BUILD—Microsoft’s annual developer conference—is the perfect showcase for inventive, innovative solutions created with the latest Microsoft technologies. As we mentioned in our previous blog, some of the technologists who have been part of the Kinect for Windows v2 developer preview program are here at BUILD, demonstrating their amazing apps. In this blog, we’ll take a closer look at how Kinect for Windows v2 has spawned creative leaps forward at two innovative companies: Freak’n Genius and Reflexion Health.

Freak’n Genius is a Seattle-based company whose current YAKiT and YAKiT Kids applications, which let users create talking photos on a smartphone, have been used to generate well over a million videos. Mercredi notes that YAKiT is already being used for storytelling, marketing, education reports, enhanced communication, or just having fun. The Kinect for Windows Team
