Automatic Feedback Directed Optimizer Merged Into GCC
The latest merged feature for next year's GCC 5 compiler release is AutoFDO support!
AutoFDO is the Automatic Feedback Directed Optimizer. AutoFDO relies on the Linux kernel's perf framework for profiling with performance counters. AutoFDO interprets the perf output and attempts to use the FDO infrastructure to produce better optimized code generation. AutoFDO according to its Google engineers is said to be noticeably faster than traditional FDO for GCC.
Ubuntu at Suzuka, Game-Changing Frictional Games, and Linux for Privacy
Today in Linux news, Softpedia.com brings us another Ubuntu spotted-in-the-wild sighting. Hamish Wilson looks at Frictional Games' body of work and how it changed computer gaming. My Linux Rig talks to Charles Profitt about his Ubuntu setup and The New American says use Linux if you're "sick of surveillance."
5 open access journals for open source enthusiasts
The ever rising cost of academic journals is a major burden for researchers. Academic libraries cannot always keep up with increases in subscription fees causing libraries to drop journals from their collection. This makes it harder for students and professors to quickly and easily access the information they need. Inter-library loan requests are an option but they do take time. Even if it only takes a few days to fill an inter-library loan request, that is still time wasted for a researcher that has a deadline. While there is no single, quick fix to the problem with the academic journal prices, there is a movement applying the open source way to academic research in an attempt to solve the problem—the open access movement.
In wake of Anonabox, more crowdsourced Tor router projects make their pitch
Last week, Ars reported on the story of Anonabox, an effort by a California developer to create an affordable privacy-protecting device based on the open source OpenWRT wireless router software and the Tor Project’s eponymous Internet traffic encryption and anonymization software. Anonabox was pulled from Kickstarter after accusations that the project misrepresented its product and failed to meet some basic security concerns—though its developers still plan to release their project for sale through their own website.
But Anonabox’s brief campaign on Kickstarter has demonstrated demand for a simple, inexpensive way to hide Internet traffic from prying eyes. And there are a number of other projects attempting to do what Anonabox promised. On Kickstarter competitor Indiegogo there’s a project called Invizbox that looks almost identical to Anonabox—except for the approach its team is taking to building and marketing the device.
Let's Pay for Open Source with a Closed-Source Software Levy
This column has often explored ways in which some of the key ideas underlying free software and open source are being applied in other fields. But that equivalence can flow in both directions: developments in fields outside the digital world may well have useful lessons for computing. A case in point is a fascinating post by James Love, Director of Knowledge Ecology International (KEI), a non-governmental organisation concerned with public health and other important issues.
It is called "The value of an open source dividend", and is a discussion of the problems the world of pharma faces because of the distorting effect of patents - problems it shares with the world of computing...
Features Of The Linux 3.18 Kernel
With Linux 3.18-rc1 arriving one week early I didn't have a chance to write a feature overview of Linux 3.18 prior to this first development release that marked the close of the merge window. For those that didn't stay up to date with our dozens of Linux 3.18 kernel articles about changes and new features, here's a concise overview.
Norway closes its open source resource centre
The government of Norway will no longer fund its open source resource centre, Friprog. Activities are wound down and the centre will be closed at the end of the year, Friprog reports. The GoOpen conference, planned for last September but postponed to May 2015, is now cancelled.
