Research in Motion is a sort of sanctuary for Qt developers – their new platform allows to reuse existing Symbian IP.
Recently, the company has held a series of shows explaining the new operating system and development methods. In the Americas, a special talk was held for BB Java developers – European developers did not get access to this.
Fortunately, the slides of all the events are now available online. Find out more here:
Recently, users of Bogdan Vatra’s Qt port for Android have started to discuss about various legal implications of using the code provided.
Konrad Rosenbaum from silmor has now posted the following to the official Qt-on-Android mailing list:
I just checked out n0.34 – the original Qt sources inside Necessitas are under the exact same license as the unmodified Qt itself: LGPL 2.1, GPL 3.0, LGPL- Exception 1.1 (you chose whatever fits best for you or you switch to the commercial license)
Most of the added sources are public domain (i.e. no strings attached). The Android platform plugin and the special qt_main for Android are under 3-clause BSD. The latter is the most limiting factor.
* Necessitas is free of charge
* Necessitas itself is Open Source
* your software can be commercial if you like (you must stop the users from
updating the Qt libs – just keep the default using Ministro as library
provider and you’ll be fine)
* your software can be under almost any Open Source license:
– LGPL 3.0 and GPL 3.0 are ok
– putting it under BSD is also ok
– I’m not entirely certain whether GPL 2.0 and LGPL 2.1 are ok, there might
be some interference from the 3rd clause of the BSD license (I’m also not
sure whether this is intended)
– I’m unfamiliar with the details of other licenses (Mozilla, Apache,
Artistic, etc.), so I can’t tell you for each one with certainty

Nokia has finally decided to let Qt go, for the better of both. We knew it was going to happen sooner than later. Seen as a “non core” business, it was only a formal announcement that was awaited from Nokia.
Digia will acquire the Qt developer tools business from Nokia, and it will take on product development, as well as the commercial and open source licensing and services business supporting Qt.
While Qt was portrayed as missing “genetic link” between OSes, targeted mainly as the savior of developers who could easily target devices powered by both Symbian OS and MeeGo, Nokia could never fully utilize it’s potential.
But for the developer community, this transition may actually prove to save Qt. While Digia plans to quickly enable Qt on Android, iOS and Windows 8 platforms, Nokia has certainly missed to see the silver lining on the clouds – making Qt as the sole cross-platform development framework.
Tommi Laitinen, SVP of International Products at Digia was quoted saying:
Now is a good time for everyone to revisit their perception of Qt. Digia’s targeted R&D investments will bring back focus on Qt’s desktop and embedded platform support, while widening the support for mobile operating systems.
Though the price of the deal is still unknown, it is rumored that Digia will pay a fraction of the US$150 million Nokia paid to acquire Trolltech, the creators of Qt. Also, about 125 Nokia staff will transfer to Digia as a result, mainly in Norway and Germany.
For someone who has been in the mobile industry since the times when apps cost 10$ a pop and were sold from ESDs, the Freemium model has always been a bit confusing. Long-term follower Nicola Peluchetti has now shared two very interesting articles which should help shine a bit of light on the topic.
Freemium has run its course
Post number one, coming via GigaOm, provides an overview of pros and cons of the Freemium model. It is ideal for all those who are interested in the history of Freemium apps, and also want to decide whether the model makes sense for their products.
Three Steps from Paid to Freemium
Story number two hits us via Betable.com. They have a talk with a Monetization expert from Rovio who explains the actual steps needed to create a successful freemium app – hit it when you have decided that Freemium fits your business concept.
Any interesting links to share?
The following changes were highlighted in what is openly advertised as a bugfix release:
fix in Qt for text editor font rendering on Mac, which would lead to incomplete rendering updates when not using the standard font
(if you build Qt Creator yourself you’ll want to either use the Qt 4.8 branch or cherry-pick 5ac8e6ef178678f500668d67fe38d149f0821029)
fix for C++ template class completion issues
various other fixes

This one is an important heads-up to all those of you who are actively developing software (or porting existing Qt IP) for RIMs BlackBerry 10 or PlayBook platforms.
In one of its ususal emails, RIM has hidden a small announcement about an “update” to the developer tools. Of course, no further info was given on the changes – but, as they are pretty severe, they do warrant attention.
So, please head to the following URL and grab the updates:

Even though development of Symbian has all but been abandoned, the open source code still remains in public domain.
Stephane Lenclud has posted the following to the largely abandoned mailing list of the Symbian DevCo:
As Symbian based devices have more or less disappeared from the shelfs and Nokia’s stocks in free fall this mailing list is obviously gone really quiet.
I’m still working with Symbian C++ though. I’ve eventually managed to get around publishing my Symbian branch using CMake as a build system.
Get the source code form the following Mercurial repository: http://hg.slions.net/hgweb.cgi/symbian/

As of this writing, not much more is known – stay tuned for further info as we get it!

Nokia really has issues keeping its hands on its staff – after having lost a few developer facing employees, another one jumps ship.
The following post has just appeared inside the Qt Ambassadors newsgroup:
Not much to add here…except that the last one should please turn off the lights…
Some years ago, reading emails on mobile devices was an acitivity which was, at minimal, uncommon – today, one can say that a huge amount of emails gets read on the run.
This – coupled with ever-improving HTML rendering on mobile devices – makes taking a look at how people read their email on the run interesting. A mass mailing company named MailChimp has compiled a fascinating report, which makes very good late-night reading.

When Nokia first announced intent to switch over to Windows Phone 7, they offered their Symbian developers a free Nokia E7 and promised to follow it up with a free Lumia when WP7 would be “on the road”.
Sadly, it looks like the Symbian developers have done their due, and are now no longer useful – we are still waiting for our Lumias. Thus, the letter below (via wmpoweruser) is likely to annoy more than one developer – a selection of MVPs somehow related to mobile will receive free Lumias:
Given that Nokia is already loosing developer goodwill at a high speed, it is questionable if this is significant at this stage – nevertheless, it shows the deprofessionalization in a clear, black-on-white fashion.
