QR Generator module for Titanium Appcelerator

After Appcelerator launched the Marketplace I managed to create and post an iOs only module that is able to create QR codes directly on the device without using an online service.It can generate all types of codes (from 1 to 40) and with any level of correction (L, M, Q, H). You can also customize the size of the resulting QR code and it will try to adapt itself to this size to remain perfectly sharp and fully visible.

Seven days with Titanium – day 7 – orientation and accelerometer

Most of the devices nowadays are equipped with an accelerometer that detect the orientation of the device or the movements the user is doing with it.Titanium exposes this functionality through its APIs so let's take advantage of that :)

Insights from the Titanium App Developer certification exam

Recently I became a Titanium Certified Application Developer (TCAD) and I was thinking on giving some insights on the exam for those who want to take it.

Possible new CSS features from Adobe

Inspired from the print world people from Adobe and Microsoft are coming with new features that might (or might not) be embedded into future CSS specs. These new features - CSS Regions and CSS Exclusions - will allow text to flow into webpages pretty much like they do in newspapers and magazines.

Dan Tamas speaking about Titanium Appcelerator at TheEvent 2011, Cáceres, Spain

Dan Tamas was invited to talk about Titanium Appcelerator at TheEvnt 2011 in Cáceres, Spain, May 14th and the purpose of this talk was to present the advantages of using this framework to develop applications for iPhone, iPad and Android devices.It was an introductory talk in order to present to the Spanish developers an alternative to ObjectiveC and the very popular Java.

Advanced Titanium Tutorial – Bonjour Networking

Titanium Appcelerator Mobile has implemented for iOs the Bonjour (or ZeroConf if you want) network protocol that allows you to connect to another device found in the same network.Before starting with the boring part - I mean the code - let's watch a video with a small demo showing 3 devices playing together :)

Seven days with Titanium – day 6 – animations and transforms

Almost any UI element can be animated and transformed, allowing you to add to your application some eye candy or simply take advantage of predefined elements to give them a new role. For those familiar with CSS3 animations this will come very easy as the concept it's pretty the same.

Animations

Pointless to say, an animation will change one or more properties of an element form the current stage to another (set by us) in a period of time.

Seven days with Titanium – day 5 – GPS and Maps

This doesn't need any kind of introduction. You can use the location on the devices to find the user's place and act accordingly. One thing good to know is that this needs the approval of the user, and for iOs > 3.2 you need to set a purpose property to let Apple know what you need it for.

Titanium.Geolocation.purpose = "GPS user coordinates";

How screen readers speak a page with HTML5 and ARIA

After seeing how AT reads a content generated with CSS pseudo-elements I was thinking to move on to HTML5. And since there are a lot of people saying we should mix HTML5 with ARIA in order to increase the accessibility of a website, then why not test and see what happens?

Testing the accessibility of the CSS generated content

This article is about how screen readers speak the content added with CSS pseudo-elements :before and :after (in CSS3 they are ::before and ::after).I am trying to learn to use AT when developing websites and recently I saw that no matter how W3C wants us to use a certain CSS element, there will always be developers/designers who will try to push the limits of the specification.While I do advise you to NOT use pseudo-elements to generate useful content (limit yourself to generating quotes or design elements), just in case somebody thinks that the cool resides in generating content with CSS because everything else is already old, let's see how people using screen readers will "benefit" from the idea.
