NEX-5 Sony SEL18200 (18-200mm) Zoom lens

"The build quality of the Sony 18–200mm OSS is excellent. In a sea of cheap plastic extreme zoom lenses it really stands out with its stylish metal body and everything is tightly assembled. The focus ring operates exceptionally smooth. The lens has no focus distance indicator/window. The rubberized zoom ring turns smooth but it's also bit stiff which also helps to suppress zoom creeping. The lens has a duo–cam design so it uses two inner lens tubes to extend the lens towards longer focal lengths. The front element does not rotate so it's suitable for using polarizers. A lens hood is also part of the package. ...

The Sony E 18–200mm f/3.5–6.3 OSS is a refreshingly different approach compared to most of the competition. It's not a purposely under–designed lens for cost–cutting measurements. This is most obvious with respect to its build quality – the stylish metal body clearly stands out from the rest of the crowd and it's a joy to handle it in the field despite the somewhat unusual/odd proportions compared to the tiny NEX camera. The optical quality is on a very decent level. It is not a flawless lens, of course, but the resolution figures are very fine in the lower portion of the zoom range and still good beyond. The distortion characteristic is about average for a lens in this class. The Sony lens produces a surprisingly low amount of vignetting even at 'large' aperture settings (even in RAW images). The primary weakness of the lens are the lateral CAs at 18mm and 200mm although that's also rather typical for such lenses. The Sony lens is a pretty obvious choice for those seeking a one–lens–solution. The resulting package size may not be pocketable but, to be honest, neither is the 18–55mm f/3.5–5.6 OSS. The 18–200mm f/3.5–6.3 OSS is not a cheap lens (neither is e.g. the Panasonic 14–140mm OIS) but it's worth it ... if you can find a decent sample."

Sony NEX-5K: an exceptionally small yet powerful hybrid camera

"Sony has designed and built an exceptionally small yet powerful hybrid camera which delivers image quality to match a digital SLR's, combined with full HD movies, the excellent Sweep Panorama mode (with a 3D firmware upgrade coming soon), high–speed shooting and more. It's a great little camera"

Freedom as in what? a debate on open source vs. free culture

"What do we mean by 'freedom'? Should Free/Libre/Open Source Software (FLOSS) necessarily be powered by radical politics of ownership and collaboration? Or is the latching of 'Free Software' ideological baggage limiting the full transformative power of 'Open Source'. How are these questions informed by licenses? Are some licenses more open than others? More ethical than others? This emotional debate has been in the heart of FLOSS from its early days and has created camps and animosities within the community.

We will examine the strong ideological differences through a provocative panel discussion with Gabriella Coleman and Zachary Lieberman."

Open Source Software Movements And Communities

In the recent five years, media and industrial interest in Free, Libre– and Open Source software has grown steadily, and a substantial academic literature on the topic has emerged. Some of this research has appeared in mainstream information systems (IS) channels such as the International Conference on Information Systems (e.g. Feller and Fitzgerald 2000, Stewart and Gosain 2001), the European Journal of Information Systems (e.g Ljungberg 2000), and the Information Systems Journal (e.g. Bergquist and Ljungberg, 2001; Gallivan 2001, Koch and Schneider 2002). However, the majority of OSS research has been conducted and disseminated by the international software engineering community, and has been shaped by the “hard issues” focus characteristic of that community. Obviously there are many more perspectives on open source than the software product itself and the development process leading to it. OSS contains many socio–cultural and socio–technical issues that are at the heart of (virtual) community related research.Bergquist, M. and Ljungberg, J. 2001, The Power of Gifts: Organizing Social Relationships in Open Source Communities.
