A First Look At Red Hat Developer Studio 149

Posted by kdawson from the ides-of-august dept.
juanignaciosl writes "The first beta of Red Hat Developer Studio was published yesterday. RHDS seems promising. This IDE is a bunch of Eclipse plugins that comes from the fusion of JBoss IDE and Exadel Studio. The main advantages it offers are: JSF development improved, in particular integrating RichFaces and Ajax4JSF libraries; Seam (next J2EE middleware standard?) integration; and plugins for JBoss, Hibernate... Here are my first impressions."

Submission + - An Optical Solution For an NP-Complete problem? (opticsexpress.org)

Submitted by 6
6 writes: Tobias Haist and Wolfgang Osten have proposed a novel idea for solving the traveling salesman problem...

We introduce an optical method based on white light interferometry in order to solve the well-known NP-complete traveling salesman problem. To our knowledge it is the first time that a method for the reduction of non-polynomial time to quadratic time has been proposed. We will show that this achievement is limited by the number of available photons for solving the problem. It will turn out that this number of photons is proportional to NN for a traveling salesman problem with N cities and that for large numbers of cities the method in practice therefore is limited by the signal-to-noise ratio. The proposed method is meant purely as a gedankenexperiment.

Submission + - Microsoft sneaking up on the graphics market? (computerworld.com)

Submitted by
Ian Lamont
Ian Lamont writes: "Microsoft has quietly been building up graphics-related R&D, reports Computerworld, noting that Microsoft employees will be presenting one out of every eight papers at SIGGRAPH 2007. And it's not a fluke — other recent Microsoft graphics-related developments include Photosynth, which has been discussed on Slashdot several times, as well as the Silverlight/Expression Studio graphics suite, which will compete with Adobe's Flash/Illustrator/Lightroom/Dreamweaver offerings. At SIGGRAPH, Microsoft will supposedly have demos of some new software including image deblurring tools and Soft Scissors, which "solves the vexing problem of how to cut and paste an image from one background to another if the image's edges — hair blowing in the wind, blades of grass — are very complex." Microsoft's competitors aren't sitting down. Adobe's CEO, calling Microsoft a "$50 billion monopolist," has questioned whether Silverlight will be compatible with non-Windows operating systems, and Google has also been building up its own graphics-related software products, such as the 3D modeling tool SketchUp, and Google Earth."

Submission + - Court convicts Skype for breaching GPL

Submitted by terber
terber writes: In Munich a German court once again upheld the GPL2 and convicted Skype (based in Luxembourg) of violating GPL by selling the Linux-based VoIP phone "SMCWSKP 100" without proper source code access. Skype later on added a flyer to the phones with an URL where to obtain the sources, but the court found this insufficient as this was in breach of GPL section 3. Plaintiff was once again Netfilter developer Harald Welte, who runs http://gpl-violations.org/. The decision is currently only available in German at http://www.ifross.de./ News source (German): www.golem.de/0707/53684.html

Submission + - Why Linux has failed on the desktop: Con Kolivas (apcmag.com)

Submitted by

SlinkySausage writes: "Linux is burdened with "enterprise crap" that makes it run poorly on desktop PCs, says kernel developer Con Kolivas who recently walked away from years of work on the kernel in despair. APCmag.com has a lengthy interview with Kolivas, who explains what he sees is wrong with Linux from a performance perspective and how Microsoft has succeeded in crushing innovation in personal computers."

Submission + - Vista use grows as Mac OS X stays flat (computerworld.com)

Submitted by

jdelator writes: "Windows Vista's share of online users has increased every month this year, while rival Mac OS X — to which Vista has often been compared — has shown little, if any, growth, a metrics company reports. According to Net Applications, in June Windows Vista accounted for 4.52% of all systems that browsed the Web, up from January's 0.18%. Vista has grown its usage share each month since its release to consumers Jan. 30, hitting 0.93% in February, 2.04% in March, 3.02% in April and 3.74% in May. Apple Inc.'s Mac OS X, meanwhile, accounted for 6.22% in January and hit its high point of 6.46% in May, but it slipped back to 6% in June. If Vista's uptake trend continues, it should pass Mac OS X in Web usage share by the end of August."
