FLOSS Impact 2006 The European Commission released a study of the economic impact of Free/Libre or Open Source Software (FLOSS) on the European ICT sector in Key findings: FLOSS potentially saves industry over 36% in software R&D investments Increased profits, or invest more usefully spent in further innovation Source:

Job demographics Only 7% of programmers in the US work in packaged software companies 30% work in sectors producing mainly custom software / integration / support Almost 60% work in the “user sector” - finance, government, manufacturing, retail, etc Source:

16% of software spending in the US is on packaged proprietary software (19% in EU) >50% is in-house software development (30% in EU) Rest is custom software Spendings Source:

68% incorporated FLOSS in their products in 2006 Rishab Aiyer Ghosh Licensed under: Creative Commons cc-nd-nc Source:

Gartner predicts 80% will include Free and Open Source software in their products in 2012

Take home You might reduce R&D investments with 34% by reusing software made by volunteers and free or dual license software companies You might increase your market opportunity with more than 50% targeting in-house and custom development with free software Source:

Stopmotion Move objects in steps, taking pictures between each move. Combine it to a movie

Built with Qt Best student project 2006

They succeeded by ● Heavy use of free software development methods and tools from the start ● Cooperation with others, interacting with real users for evaluation and feedback ● The students listened to both their internal advisor and input from OSS developers ● They used free software tools and methods ● They participated and was active at all the developer gatherings ● They showed up on appointments

Thanks Q & A

Please join us Getting experience with developing cross device, cross platform software

Free us from the silos Today many device manufactures and software developers maintain several code bases for the same application, when targeting different operating systems and devices. Qt can increase Nokia productivity and time to marked, targeting desktop, mobile and embedded platforms with a single code base. Of several benefits with Qt, speed to marked and reduced maintenance cost are great advantages for Nokia and everyone else using Qt.

Foundation for future innovation Increased use of Qt, including contributions and feedback from innovative projects, will ensure that Qt is of the highest quality possible. The widespread use of Qt both in free and proprietary projects, translates into greater richness and stability across and between platforms. A continues improvement of Qt gains both Nokia and everyone else who uses it.
