Proper error detection and recovery is often ignored by UNIX developers. The lack of exceptions from the C language and the rudimentary error mechanisms from the standard C library certainly contribute to this. This article familiarizes you with the UNIX standard error reporting mechanism, the errno global variable. You'll also learn about a couple of associated global variables ( sys_nerr and sys_errlist) and the standard functions that help you report errors to the user and (hopefully) encourages you to report and handle errors in a user-friendly way.

"With chip makers continuing to increase the number of cores they include on each new generation of their processors, perhaps it's time to rethink the basic architecture of today's operating systems, suggested Dave Probert, a kernel architect within the Windows core operating systems division at Microsoft."

"The city of Amsterdam has been involved for several years in building Citynet, a partnership between the city and two private investors to wire 40000 Amsterdam buildings with fiber. And it's not just fiber, it's open access fiber - any ISP can sign up to use the infrastructure and deliver ultra-fast Internet access. In 2008, the European Union ruled that the city's involvement in the project was in fact legal, and that it was not improperly interfering in the market. We asked Herman Wagter, CEO of the company that built Citynet fiber project, to talk about how he got the job done, and to explain the challenges of rolling out fiber in a densely crowded European city." In case you're wondering: no, I don't live in Amsterdam. My small hick town has plans for fibre too, however.

"In this article, the authors investigate the impact of DRM restrictions on the demand for music downloads. [A new model] estimates the impact of DRM on consumers' willingness to pay for songs (both favorites and nonfavorites) and on the producer revenues and profits. Based on two studies of more 2000 college students, the results suggest that despite the potential advantages offered by some DRM restrictions, on balance the elimination of DRM has a net positive impact on producer revenue, profit, and consumer welfare."

"By encouraging more people to post videos in Wikipedia articles, we can bring theora video played in html5 to a very large audience. Currently, there are very few wikipedia articles that have videos. We hope that this campaign will bring thousands more to the site and show people how great theora can be. HTML 5 video, which plays without Flash, is a wonderful step towards a more open web - but if it depends on proprietary codecs like h.264, we will still be stuck with a gatekeeper for online video."
