Exploring Jquery Mobile 1.4.0

    The Jquery Mobile team released a new stable version 1.4.0 on December 23, 2013, an early Christmas gift for all the Jquery Mobile fans including myself. The main thing that people noticed in this version was the change in the default theme and design. Jquery Mobile has gone flat with version 1.4.0, some believe that this change has been inspired by the flat metro design style Apple adopted for iOS 7. However, there have not been just cosmetic changes, but many more changes and we will take a look at these today.

Default theme (Swatch A)

    Version 1.4.0 is focused on performance improvements and reviewing widgets. A new default theme has been introduced with SVG icons. A few new widgets have been introduced with this version which include a flipswitch widget, a generic filter widget named "filterable", popups with arrows, tooltips for sliders and 2 new Jquery UI widgets have been intergrated - the Tabs widget and the Date Picker widget. The filterable widget can be used with listviews, collapsibles, tables, controlgroups, select and even a simple paragraph of plain text.

    As compared to the earlier versions, in the current version of Jquery Mobile, DOM manipulations have been reduced to improve performance. Generation of inner markup for elements styled as buttons has been completely removed and in many cases, the frameworks just adds classes to the native element during enhancement and even the number of classes have been reduced.

    A new default theme with a flat, more modern design has been introduced in this version. Also the number of swatches has been reduced from 5 to 2; a light "A" swatch and a dark "B" swatch. The new theme also includes a completely new icon set which has vector-based SVG icons. A fallback to external PNG icons on browsers that don't support inline SVG and also been included.

    In this version of Jquery Mobile, the slider and the range slider widgets have been deprecated. These widgets will be worked on and supported again in the future versions. Data-role="fieldcontain" has also been deprecated and has been replaced by class ui-field-contain. Several other classes like ui-icon-shadow have also been deprecated in this version.

    2 new events - "Swipe to Delete" and "Swipe to navigate" have been introduced with this version. Many developers, I am sure must have been very happy to see these 2 features included in this release. These are very popular events that are a common requirement of most mobile web applications.

    With all these new changes introduced in this version and many more new interesting features proposed for the future releases, Jquery Mobile is becoming one of the most prominent mobile web framework looking at the current market trends. Jquery Mobile is enhancing its existing framework by making it lighter and at the same time loading it with several features.

    Drop a line to share your experiences with the new version of this exciting mobile web framework. Feel free to suggest any new features that I missed to cover in this post. Till next time, have fun exploring the new Jquery Mobile.

Geodesic Polyline

Today we will have a look at a very interesting polyline example - "The geodesic polyline". Now the first question that will pop is "What is geodesic?". Mathematically, geodesic means the shortest line between two points on a mathematically defined surface, as a straight line on a plain or an arc of a great circle or sphere.

    The next question after reading the above definition is clearly, "Why do we need geodesic polylines?" and that would be followed up with "What is this Great Circle?". We will discuss this first, before we move on to the actual example today. The example is very very similar to the normal polyline example, with just a small change.

    Having said so, I will now try to explain why we need a geodesic polyline? The shortest distance between two locations on the earth is rarely a straight line as the earth is roughly spherical in nature. So any two points on the earth, even if they are very close lie on a curve and not …

Difference between word-break: break-all versus word-wrap: break-word

The 2 CSS properties word-break: break-all and word-wrap: break-word appear to work in the same way or generate the same output, but there is a slight difference between the 2 and we will be discussing these differences today.



    Take a look at the example above. The difference is quite evident, however I will try to explain it further.

word-break: break-all Irrespective of whether it’s a continuous word or many words, break-all breaks them up at the edge of the width limit even within the characters of the same word
word-wrap: break-word This will wrap long words onto the next line.break-word adjusts different words so that they do not break in the middle.
    So if you have many fixed-size spans which get content dynamically, you might just prefer using word-wrap: break-word, as that way only the continuous words are broken in between, and in case it’s a sentence comprising many words, the spaces are adjusted to get intact words (no break within a word).     In case you want to exp…

Where does Google get it's live traffic data from?

Referring to a post that I wrote earlier, Google’s - Live traffic Layer, ever wondered how Google collected this data? I was wondering the other day, how Google received live data to display it on their maps as a layer! I looked up the web and found something very interesting and am sharing the same with you all.As we all know, the traffic layer is available most accurately in several states in USA. Most major metro areas in the US have sensors embedded in their highways. These sensors track real time traffic data. Easy to miss at high speeds (hopefully anyway, traffic permitting), more commonly noticed may be the similar sensors that often exist at many busy intersections that help the traffic lights most efficiently let the most amount of people through. The information from these tracking sensors is reported back to the Department of Transportation (DOT). The DOT uses this data to update some of the digital signs that report traffic conditions in many metro areas. They also…

Ground Truth - How Google Builds Maps

Todays's article is cross posted from The Atlantic's Tech section. The article was posted by Alexis Madrigal who is a senior editor at The Atlantic, where he oversees the Technology channel. So, thanks to The Atlantic and Alexis Madrigal, we will have an exclusive look inside Ground Truth, the secretive program to build the world's best accurate maps.


    Behind every Google Map, there is a much more complex map that's the key to your queries but hidden from your view. The deep map contains the logic of places: their no-left-turns and freeway on-ramps, speed limits and traffic conditions. This is the data that you're drawing from when you ask Google to navigate you from point A to point B -- and last week, Google showed me the internal map and demonstrated how it was built. It's the first time the company has let anyone watch how the project it calls GT, or "Ground Truth," actually works.
    Google opened up at a key moment in its evolution. The co…
