Catching bugs with Opera Dragonfly
AN OVERVIEW OF OPERA'S DEVELOPER TOOLS

Patrick H. Lauke / RIT++ / Moscow / 3 April 2012

Opera Dragonfly
●
“HTML5 web application”
●
uses application cache (needs one-time load)
●
rapid release cycle with 3 release channels

JavaScript debugging
●
syntax errors are “simple” – throw errors
●
more insidious: logic errors
●
difficult to see what's going on inside script

What's going on?
●
throwing alerts
●
breakpoints – watches, stack, inspection
●
console API

Remote debugging
●
in Opera Dragonfly forever
●
true remote debugging (look ma', no cables)

Why emulate?
● real touch events
●
viewport
●
reacts correctly to media queries
(device-pixel-ratio, device-width, … )

Speaker: Aurelio De Rosa Language: English People don't give a f**k of JavaScript. You shouldn't either. We are here to do stuff, whether you call them websites, web applications, web services or hybrid apps. People want to perform tasks, not listen to you talking about your favorite programming language. So, use the one you're more comfortable with and just release the next big thing. But, if your favorite language is JavaScript, let's write better code. What does better mean? Better for developers, better for devices, better for users. In this talk, I'll describe some of the latest JavaScript APIs that can help you to develop great code. In a bunch of minutes, you'll see how to use: - The High Resolution Time and the User Timing APIs to help yourself testing your code performances; - The Page Visibility and the Battery Status APIs to take care of devices' resources; - The Vibration and the getUserMedia APIs to create better User Experiences. 4Developers: http://4developers.org.pl/pl/

JAVA INTRODUCTION

Prof Ansari

Java is a general-purpose; object oriented programming language developed by Sun Microsystems of USA in 1991. This language was initially called “Oak” by James Gosling, but was renamed “Java” in 1995. Java (with a capital J) is a high-level, third generation programming language, like C, Fortran, Smalltalk, Perl, and many others.Java was initially designed to solve on a small scale could also be applied to the Internet on a large scale. This realization caused the focus of Java to switch from consumer electronic to Internet Programming.Java was designed for the development of software for consumer electronic devices like TVs, VCRs, Toasters, Microwaves ovens and such other electronics devices.Java is a first programming language that is not tied to any particular hardware or operating system. Programs developed in Java can be executed anywhere on any system.

Functional Testing is system level , end-to-end testing of your app from a user's perspective. Automating the process of functional testing of your app offers several benefits – it saves time and effort, it's repeatable, simplifies regression testing, enables testing with large data sets and it can be tied into your Continuous Integration process. UI Automations is an automated functional test framework from Apple. Here, user interactions are driven by test scripts are written in JavaScript and executed using the Instruments Automation tool.

In this FITC SF 2010 session, Guilhem explains what makes development of mobile applications development so special compared to Rich Internet Applications. You will learn what it means to be "native", why it matters for performance and user experience, and how OpenPlug's ELIPS Studio turns your Flex code into a native app. You'll also hear about the bewildering diversity in mobile operating systems and how ELIPS Studio helps keeping fragmentation at bay. Taking examples from popular apps created by ELIPS Studio users and some hands-on code examples, Guilhem will take you through the entire journey of specifying, designing, developing, testing and publishing an app created in Flex with ELIPS Studio on popular devices.

At TLabs, we respect the demand of time & love to go along with it. Acknowledging the trends we serve neatly designed syllabus that explores jQuery covering the thorough fundamentals of JavaScript. Having a basic knowledge of JavaScript will go a long way in understanding, structuring, and debugging your code. After the completion of this course, you will be able to create plug-ins on top of the JavaScript library to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and web applications as well.

WCAG is supposed to give us a reasonably objective way of saying whether or not the sites we are building/auditing are "accessible" (to a particular baseline). However, they are only as useful as our understanding and interpretation of the guidelines' normative text. And, of course, it is not perfect - with some omissions, handwaving, and straight-up loopholes. So where does this leave developers and auditors? In this talk - a reprise of a previous talk, now updated to cover new SCs from WCAG 2.2 - Patrick may not have all the answers, but he'll have a good rant around the subject anyway...

Vanilla HTML is limiting and boring. Our clients demand highly engaging and interactive web experiences. And wouldn’t you know, with just a bit of HTML and JavaScript we can craft amazing custom controls, widgets and effects that go far beyond the confines of traditional static markup. But how can we ensure that these custom experiences are both understandable and usable for people with disabilities, and in particular those using assistive technologies such as screen readers? In this talk, we will look at the basics of making some common custom-built components accessible - covering how browsers and assistive technologies interact, the limitations of HTML, and how ARIA can help make interactive experiences more accessible. In addition, we will explore some of the recent additions in ARIA 1.1, as well as some particular challenges when it comes to traditional ARIA patterns and assistive technologies on mobile/tablet/touch devices.
