A Mobile Developer Lab the Size of a Country!

2012-05-17T15:41:30Z

Last week we attended with Bertrand Dufresne the 2012 edition of Mobilism in Amsterdam, an awesome event set up by many great people, among them Peter-Paul Koch, Stephen Hay and Krijn Hoetmer.

One of the most inspiring and useful ideas we brought from Mobilism was the creation of a mobile testing lab, covering a wide array of devices, allowing companies of all sizes to offer access to devices from different brands and models. This idea was presented by both Remy Sharp and Jeremy Keith, and it has taken the form of a physical testing lab set up in Brighton, UK, as described by Jeremy himself.

Of course, Switzerland is a country, and slightly bigger than Brighton, but as a country, it is not that big after all. Imagine an online database of devices, including their geographical location, helping developers to share devices with each other, to reserve time slots, and this not only in Geneva or Zürich, but all over the country.

Very often we developers would love to be able to test our latest app in some weird combination of mobile OS or browser or technology, and we wonder whether someone has such a device to lend for a little while, the time of debugging our code or testing our site. That’s the whole spirit of this project.

So far the idea, thus, is to start the discussion and start collecting information. Towards this goal, I’ve opened a project site to share conversations, files and other items of interest around this idea.

If you want to join this effort, please contact me and I’ll open a account for you to the project. We would love to have a large array of devices for testing, and if we all collaborate, we could have a country-wide database of devices! I think this is a goal that will provide lots of utility for all of us.

Introducing the Henri Dès iPhone App: La Radio HD!

2012-05-14T06:20:07Z

We are extremely happy to announce the immediate availability of the Henri Dès iPhone application on the App Store. This is the result of a collaboration with our dear friends Fabien and Sena from We Studio Lausanne, and is a mobile frontend for the Radio Henri Dès website, also created by We Studio.

This application streams more than 250 songs in high definition, without ads or interruptions, non-stop 24/7! It also provides quick access to the songs by Henri Dès in your iOS device, and shortcuts to buy more from the iTunes store.

[Henri Dès][4] is a Swiss singer and songwriter immensely popular with children in francophone countries. He represented Switzerland in the 1970 Eurovision Song Contest with the song “Retour”, earning the fourth position. Publishing since 1977 under his own label, Marie-Josée Productions, he has written, recorded and released 25 records, and has toured extensively in Switzerland, France, Belgium and Canada.

This week: Mobilism 2012 Amsterdam

2012-05-07T09:22:57Z

This week we are very happy to announce that will be attending the [2012 edition of Mobilism Amsterdam][4] organized by Peter-Paul Koch (of QuirksMode fame), Krijn Hoetmer and Stephen Hay!

From the Mobilism site:

Mobile is becoming increasingly important to web designers and developers because users expect a site to work on their phones. Simultaneously, the web is becoming increasingly important to the mobile world because it is the only way to deploy an application to any phone.
Nowadays most web conferences feature a mobile session, and most mobile conferences a web session. The obvious next step is Mobilism: a conference wholly dedicated to mobile web design and development.
Just like in 2011 we’ll invite some of the best speakers from the web development and the mobile world to guide you through the confusing jumble of platforms, screen sizes, and browsers that is the mobile ecosystem.

Check out the list of speakers: Horace Dediu, James Pearce, Remy Sharp, Jeremy Keith, Brian LeRoux and more!

If you are around let’s meet and talk about the mobile web.

Introducing the Teaching Editor

2012-04-24T16:00:42Z

We are very happy to introduce our latest open source project: the [Teaching Editor][13]. This project provides an online editor that automatically reloads the contents of an iPhone-sized frame. It also provides students with a read-only mode, allowing them to follow in real time whatever code is written in the screen of the teacher, and they can also download the current state of the code at any moment.

It is built exclusively in JavaScript, using the following libraries:

Requirements

Server

Use Homebrew to install Node.js in your system. Also, install npm and install Express and Socket.IO with npm.

The install.sh script performs all the required operations to install external dependencies in your system.

Client

The client has been tested successfully on several combinations of operating systems and browsers:

Cross-platform browsers:
- Firefox 10
- Chrome 17
- Opera 11
OS X “Lion”
- Safari 5.1
Windows 7
- Internet Explorer 9
iOS
- Mobile Safari for iOS 5.1 on the iPad (in this case, however, scrolling is not possible)

Pay attention to the fact that the mobile libraries themselves might not be compatible with some of these browsers (in particular, Sencha Touch only works on Webkit-based browsers).

How to Use

./install.sh (this will download the required libraries, only required once)
./launch.js (this launches the Node.js app and opens a browser window)
Students can browse to the IP shown in the dialog of the “Project / Show Share URL” menu entry.

License

This project is released under the GPLv3 license. Please check the LICENSE file for details.

Getting the Next and the Previous NSIndexPath Instances

2012-04-20T10:44:02Z

Very often, when you work with UITableViewControllers driven by NSFetchedResultsControllers, that you want to get the “previous” or the “next” elements in the results controller. Visually, this operation corresponds, from the point of view of the user, to select the cell that sits immediately above or below from the currently selected one.

Of course, you can’t just ++ on the current NSIndexPath, because these objects have both a section and a row component, and the math required to jump from one to the other can be quite cumbersome; instead, it would be useful to have a reusable set of methods, and avoid the clutter in our controllers.

I have created a very simple category on the NSFetchedResultsController class that retrieves the “next” and the “last” NSIndexPath given any other NSIndexPath; this can be dropped and reused in your projects and is very simple to use.

Interface

#import 
@interface NSFetchedResultsController (AKOLibrary)
- (NSIndexPath *)ako_incrementIndexPath:(NSIndexPath *)oldIndexPath;
- (NSIndexPath *)ako_decrementIndexPath:(NSIndexPath *)oldIndexPath;
@end

Implementation

#import "NSFetchedResultsController+AKOLibrary.h"
@implementation NSFetchedResultsController (AKOLibrary)
- (NSIndexPath *)ako_incrementIndexPath:(NSIndexPath *)oldIndexPath
{
    NSIndexPath *nextIndexPath = nil;
    id  sectionInfo = [[self sections] objectAtIndex:oldIndexPath.section];
    NSInteger rowCount = [sectionInfo numberOfObjects];
    NSInteger nextRow = oldIndexPath.row + 1;
    NSInteger currentSection = oldIndexPath.section;
    if (nextRow < rowCount)
    {
        nextIndexPath = [NSIndexPath indexPathForRow:nextRow inSection:currentSection];
    }
    else
    {
        NSInteger sectionCount = [[self sections] count];
        NSInteger nextSection = currentSection + 1;
        if (nextSection < sectionCount)
        {
            nextIndexPath = [NSIndexPath indexPathForRow:0 inSection:nextSection];
        }
    }
    return nextIndexPath;
}
- (NSIndexPath *)ako_decrementIndexPath:(NSIndexPath *)oldIndexPath
{
    NSIndexPath *previousIndexPath = nil;
    NSInteger nextRow = oldIndexPath.row - 1;
    NSInteger currentSection = oldIndexPath.section;
    if (nextRow >= 0)
    {
        previousIndexPath = [NSIndexPath indexPathForRow:nextRow inSection:currentSection];
    }
    else
    {
        NSInteger nextSection = currentSection - 1;
        if (nextSection >= 0)
        {
            previousIndexPath = [NSIndexPath indexPathForRow:0 inSection:nextSection];
        }
    }
    return previousIndexPath;
}
@end

How to use

To use this class, just do the following:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:19 inSection:4];
NSIndexPath *next = [controller ako_incrementIndexPath:indexPath];
NSIndexPath *previous = [controller ako_decrementIndexPath:indexPath];

If the NSIndexPath (19,4) was the last of whole table, next would be nil. The same, if NSIndexPath was the first (0, 0), then previous would be nil. In all other situations, the next and previous index paths will correspond to the cells immediately above or below from the current table.

Hope this helps!Similar Posts:

Third Edition of the Mobile Web Training in Zürich

2012-04-16T06:48:45Z

Simplificator and akosma software are thrilled to announce the third edition of our successful three day training about mobile web app development using jQuery Mobile, Sencha Touch and PhoneGap in Zürich on May 16th, 17th and 18th!

Today, having a mobile application online is a must. But there are multiple platforms to write for, each with their own language, idioms and pitfalls. Luckily there is a simple solution that allows to write once and deploy on all modern mobile devices: HTML5 and JavaScript.

What others have been saying

“Die Inhalte wurden lebendig und Step-by-Step präsentiert”
“Merci, das war ein sehr lehrreicher Kurs”

Easy, quick dev of “native” applications

This three day intensive course takes you from being a web developer to being a mobile developer. We take you through the basics of writing HTML5 applications for mobile devices, cover the additional APIs that allow you to access the functions of the devices (like storage, geo-location, accelerometers) and put you in control of deploying an application to either iOS or Android devices.

What

Overview over what HTML5 brings for mobile development
Overview over options for bringing web apps to a mobile device
In depth review of jQuery Mobile and Sencha Touch
JavaScript best practices
Bundling your app for the device with PhoneGap
Accessing your devices sensors and special features from JavaScript

There will be lots of hands-on working building an application from scratch and bringing it to life on your mobile device. We will build two applications – one with jQuery Mobile, one with Sencha Touch and bring them to “life” as native applications on a mobile device.

Prerequisites

HTML / CSS
Basic JavaScript skills
Programming experience
Laptop with either iOS SDK (Mac OSX with XCode) or Android SDK (Mac, Windows, Linux) installed and running
Mobile device (iOS, Android)

Class Size

Learning and working is best done in a relative small group. We plan on having maximum 9 people in this class so that we can spend enough time with each of our students.
