Access to main memory from the processor is mediated (and accelerated) by the L2 and L3 memory caches; developers working on performance-critical code quickly learn that cache utilization can have a huge effect on how quickly an application (or a kernel) runs. But, as Fenghua Yu noted in his LinuxCon Japan 2016 talk, the caches are a shared resource, so even a cache-optimal application can be slowed by an unrelated task, possibly running on a different CPU. Intel has been working on a mechanism that allows a system administrator to set cache-sharing policies; the talk described the need for this mechanism and how access to it is implemented in the current patch set.
If your familiarity with Bitcoin and Blockchain is limited to having heard about the trial of Silk Road’s Ross Ulbricht, you can be forgiven -- but your knowledge is out of date. Today, Bitcoin and especially Blockchain are moving into the mainstream, with governments and financial institutions launching experiments and prototypes to understand how they can take advantage of the unique characteristics of the technology.
Cybik comes back on how he came to know and use Linux in the first place, his gaming habits, how he got involved into the Skullgirls port, and shares with us his outlook on the Linux gaming landscape. The podcast is just an hour long and you can either download it below, and use our RSS feed (that has the additional benefit of making it easy for you to get new episodes from now on):
It’s been a while since I wrote a post here. A lot has happened since then. Now Gnome-games fully supports PlayStation games, with snapshoting capabilities. The next thing I’m working on is multi-disc support, specially for PlayStation titles. So far, there’s a working propotity although a lot needs to be re-engineered and polished. This last part of the project has involved working both in UI, persistance and logic layers.
In the not so distant past, Solus followed a static point release model. Our most current release at this time is 1.2, with a 1.2.1 planned to drop in the near future. However, we also recently announced our move to a rolling release model. As such, these two schools of thought are in contradiction of one another.
On the heels of Oracle’s July 2016 security updates for Java 8, the icedtea folks have released version 3.1.0 of their build framework so that I could create packages for OpenJDK 8u101_b13 or “Java 8 Update 101 Build 13” (and the JRE too of course).
I decided to do an update of my “pipelight” package. I had not looked at it for a long time, basically because I do not use it anymore, but after I upgraded my “wine” package someone asked if I could please write up what could be done for wine-pipelight.
As you know, pipelight is a Linux plugin wrapper for Mozilla-compatible browsers which lets you install and use Windows plugins on Linux. This configuration enables you to access online services which would otherwise be unavailable to you on a Linux platform. The pipelight plugin wrapper uses wine to load the Windows software.
Cloud computing is fast growing in the world of computer and Internet technology, many companies, organizations and even individuals are opting for shared pool of computing resources and services. For starters, Cloud computing is a type of Internet-based computing where users consume hosted services on shared server resources.
There are fundamentally three types of cloud computing available today: private, public and hybrid cloud computing.

It's been a while since we last heard something from the Deluge project, an open-source and cross-platform BitTorrent client that's available for GNU/Linux, Mac OS X, and Microsoft Windows operating systems.
Deluge is quite a popular software for downloading torrent files over the Internet, and it comes with pretty much everything you would expect from a BitTorrent client, including protocol encryption, Universal Plug and Play (UPnP), Distributed Hash Table (DHT), uTorrent Peer Exchange, wet-PMP, and, of course, the ability to manage the program remotely via a web browser.
Now that the final release of the Krita 3.0 digital painting software has been released for our personal computers, the time has come for the project's development team to concentrate their efforts on the first point release.

That's right, Docker 1.12.0 is finally here after being in development for the past two months, during which it received a total of five Release Candidate (RC) builds that have been seeded to public testers and those who wanted an early taste of what's coming to the final Docker 1.12 release.
"We wanted to thank everyone in the community for helping us achieve this great milestone of making Docker 1.12 generally available for production environments. Docker 1.12 adds the largest and most sophisticated set of features into a single release since the beginning of the Docker project," reads the release announcement.

For those playing TORCS, The Open Racing Simulator, its performance for this driving game simulator should be slightly faster if using one of Mesa's Gallium3D drivers.
AMD developer Marek Olšák has landed a complete rewrite of state atoms inside the Gallium3D Mesa state tracker.
Long story short, Marek concluded his commit message by mentioned, "torcs is 2% faster between the previous patch and the end of this series." Every little bit counts in making the open-source driver stack more competitive. With this being in the vendor-neutral Mesa state tracker code, it should presumably also help the Nouveau driver too, in addition to RadeonSI/R600g.
Credit Suisse hosted an investors’ meeting with Red Hat Inc.’s (NYSE:RHT) President of Products Paul Cormier on Thursday, this week.
