Reader StreamingEagle writes (edited): Netflix conducted a large-scale study comparing x264, x265 and libvpx (Google-owned VP9), under real-world conditions, and found that x265 encodes used 35.4% to 53.3% fewer bits than x264, and between 21.8% fewer bits than libvpx, when measured with Netflix's advanced VMAF assessment tool. This was the first large-scale study to use real-world encoder implementations, and a large sample size of high quality, professional content.A Netflix spokesperson explained why they did the test in the first place; "We wanted to understand the current state of the x265 and libvpx codec implementations when used to generate non-realtime encodes optimized for OTT use case. It was important to see how the codecs performed when testing on a diverse set of premium content from our catalog. This test can help us find areas of improvement for the different codecs."

Long-time Slashdot reader JRiddell writes: A unique coming together of open source communities is happening in Berlin over the next week. QtCon brings together KDE, Qt, VLC and FSF-E to discuss free software, open development, community management and proprietary coding. Live streams of many of the talks are available now. The opening keynote spoke of open data and collaborative coding freeing accessibility information. 13 tracks of talks cover Community, Web, Best practices, Automotive, Mobile and Embedded, Let's talk business, Tooling, QtQuick, Multithreading, OpenGL and 3D.

"Europe and South America are the biggest hotspots for open-source use in government," reports Network World, while Bulgaria requires all software written for the government to be FOSS. Slashdot reader alphadogg quotes their report: It's become increasingly common over the past decade or so to see laws being passed to either mandate the use of open-source software or, at the very least, encourage people in government who make procurement decisions to do so. Here's a map of the status of open-source laws around the world.

Reader JImbob0i0 writes: After almost another year without a release and another major CVE leaving users vulnerable for that year the Chairman of the Project Management Committee has started public discussions on what it will entail to retire the project, following the Apache Board showing concern at the poor showing.
It's been a long battle which would have been avoided if Oracle had not been so petty. Did this behaviour actually help get momentum in the community underway though? What ifs are always hard to properly answer. Hopefully this long drawn out death rattle will finally come to a close and the wounds with LibreOffice can heal with the last few contributors to AOO joining the rest of the community.

Ruby on Rails Creator and founder/CTO of Basecamp, David Heinemeier Hansson has responded to questions submitted by Slashdot readers. Read on for his answers.

Slashdot reader mspohr shares an article about "General Electric 're-inventing' itself as a software start-up." Jeffrey R. Immelt, the CEO of America's largest manufacturer, describes how he realized that data collected from their machines -- like turbines, engines, and medical-imaging equipment -- could be as valuable as the machines themselves. Now G.E. is hiring software engineers and data scientists from Amazon, Apple, Facebook and Google to try to transform the company into a "124-year-old startup" to take advantage of the Internet of Things and offer futuristic new services like predictive maintenance.

The Times calls it "the next battlefield as companies fight to develop the dominant software layer that connects the machines," adding that by 2020 there will be 100 times as much data flowing from G.E.'s machines. Now G.E. Digital is using the open source PaaS, Cloud Foundry, to develop Predix, a cloud-based operating system for industrial applications like monitoring and adjusting equipment in the field, whether it's an oil-field rig or a wind-farm turbine. To help transform the company into a digital powerhouse, they're building a 1,400-employee complex in San Ramon, California "designed to suit the free-range working ways of software developers: open-plan floors, bench seating, whiteboards, couches for impromptu meetings, balconies overlooking the grounds and kitchen areas with snacks." And they've also launched the Industrial Dojo program "to accelerate the ability for developers to contribute code that enables the Industrial Internet".

Long-time Slashdot reader sfcrazy writes: During LinuxCon, Torvalds was full of praise for GNU GPL: "The GPL ensures that nobody is ever going to take advantage of your code. It will remain free and nobody can take that away from you. I think that's a big deal for community management... FSF [Free Software Foundation] and I don't have a loving relationship, but I love GPL v2. I really think the license has been one of the defining factors in the success of Linux because it enforced that you have to give back, which meant that the fragmentation has never been something that has been viable from a technical standpoint."

And he thinks the BSD license is bad for everyone: "Over the years, I've become convinced that the BSD license is great for code you don't care about," Torvalds said.
But Linus also addressed the issue of enforcing the GPL on the Linux foundation mailing list when someone proposed a discussion of it at Linuxcon. "I think the whole GPL enforcement issue is absolutely something that should be discussed, but it should be discussed with the working title 'Lawyers: poisonous to openness, poisonous to community, poisonous to projects'... quite apart from the risk of loss in a court, the real risk is something that happens whether you win or lose, and in fact whether you go to court or just threaten: the loss of community, and in particular exactly the kind of community that can (and does) help. You lose your friends."

Continuing its rapid release cycle, ReactOS has unveiled version 0.4.2 of its free "open-source binary-compatible Windows re-implementation." Slashdot reader jeditobe reports that this new version can now read and write various Linux/Unix file systems like Btrfs and ext (and can read ReiserFS and UFS), and also runs applications like Thunderbird and 7-Zip. ReactOS 0.4.2 also features Cygwin support, .NET 2.0 and 4.0 application support, among other updated packages and revised external dependencies such as Wine and UniATA. The team also worked to improve overall user experience...

ReactOS is free. You can boot your desktop or laptop from it. It looks like Windows (a 10-year-old version, anyway), so you already know how to use it. And it'll run some Windows and DOS applications, maybe including DOS games that regular 64-bit Windows can no longer touch. These videos even show ReactOS running Elder Scrolls: Skyrim and Doom 3.

An anonymous reader quotes a report from BetaNews: Today, the first beta of Ubuntu Linux 16.10 sees release. Once again, a silly animal name is assigned, this time being the letter "Y" for the horned mammal, "Yakkety Yak." This is also a play on the classic song "Yakety Yak" by The Coasters. Please be sure not to "talk back" while testing this beta operating system! "Pre-releases of the Yakkety Yak are not encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu flavor developers and those who want to help in testing, reporting and fixing bugs as we work towards getting this bos grunniens ready. Beta 1 includes a number of software updates that are ready for wider testing. These images are still under development, so you should expect some bugs," says Set Hallstrom, Ubuntu Studio project lead. He adds: "While these Beta 1 images have been tested and work, except as noted in the release notes, Ubuntu developers are continuing to improve the Yakkety Yak. In particular, once newer daily images are available, system installation bugs identified in the Beta 1 installer should be verified against the current daily image before being reported in Launchpad. Using an obsolete image to re-report bugs that have already been fixed wastes your time and the time of developers who are busy trying to make 16.10 the best Ubuntu release yet. Always ensure your system is up to date before reporting bugs." Here are the following download links: Lubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio.

An anonymous reader quotes a report from Neowin: The open-source disk cleaning application, BleachBit, got quite a decent ad pitch from the world of politics after it was revealed lawyers of the presidential hopeful, Hillary Clinton, used the software to wipe her email servers. Clinton is currently in hot water, being accused of using private servers for storing sensitive emails. "[South Carolina Representative, Trey Gowdy, spoke to Fox News about Hillary Clinton's lawyers using BleachBit to wipe the private servers. He said:] 'She and her lawyers had those emails deleted. And they didn't just push the delete button; they had them deleted where even God can't read them. They were using something called BleachBit. You don't use BleachBit for yoga emails or bridesmaids emails. When you're using BleachBit, it is something you really do not want the world to see.'" Two of the main features that are listed on the BleachBit website include "Shred files to hide their contents and prevent data recovery," and "Overwrite free disk space to hide previously deleted files." These two features would make it pretty difficult for anyone trying to recover the deleted emails. Slashdot reader ahziem adds: The IT team for presidential candidate Hillary Clinton used the open source cleaning software BleachBit to wipe systems "so even God couldn't read them," according to South Carolina Rep. Trey Gowdy on Fox News. His comments on the "drastic cyber-measure" were in response to the question of whether emails on her private Microsoft Exchange Server were simply about "yoga and wedding plans." Perhaps Clinton's team used an open-source application because, unlike proprietary applications, it can be audited, like for backdoors. In response to the Edward Snowden leaks in 2013, privacy expert Bruce Schneier advised in an article in which he stated he also uses BleachBit, "Closed-source software is easier for the NSA to backdoor than open-source software." Ironically, Schneier was writing to a non-governmental audience. Have any Slashdotters had any experience with BleachBit? Specifically, have you used it for erasing "yoga emails" or "bridesmaids emails?"

VideoLan President and Lead Developer of VLC Jean-Baptiste Kempf has responded to questions submitted by Slashdot readers. Read on to find out about the upcoming VideoLAN projects; how they keep VLC sustainable; what are some mistakes they wish they hadn't made; and what security challenges they face, among others!

The creator of Linux, Linus Torvalds, posted his famous message announcing Linux on August 25, 1991, claiming that it was "just a hobby, won't be big and professional like gnu." ZDNet's Steven J. Vaughan-Nichols caught up with Linus Torvalds and talked about Linux's origins in a series of interviews: "SJVN: What's Linux real birthday? You're the proud papa, when do you think it was? When you sent out the newsgroup post to the Minix newsgroup on August 25, 1991? When you sent out the 0.01 release to a few friends?

LT: I think both of them are valid birthdays. The first newsgroup post is more public (August 25), and you can find it with headers giving date and time and everything. In contrast, I don't think the 0.01 release was ever announced in any public setting (only in private to a few people who had shown interest, and I don't think any of those emails survived). These days the way to find the 0.01 date (September 17) is to go and look at the dates of the files in the tar-file that still remains. So, both of them work for me. Or either. And, by the way, some people will argue for yet other days. For example, the earliest public semi-mention of Linux was July 3: that was the first time I asked for some POSIX docs publicly on the minix newsgroup and mentioned I was working on a project (but didn't name it). And at the other end, October 5 was the first time I actually publicly announced a Linux version: 'version 0.02 (+1 (very small) patch already).' So you might have to buy four cakes if you want to cover all the eventualities." Vaughan-Nichols goes on to pick Linus' brain about what he was doing when he created Linux. In honor of Linux's 25th birthday today, let's all sing happy birthday... 1... 2... 3...

An anonymous reader writes: Researchers at Princeton announced at Hot Chips this week their 25-core Piton Processor. The processor was designed specifically to increase data center efficiency with novel architecture features enabling over 8,000 of these processors to be connected together to build a system with over 200,000 cores. Fabricated on IBM's 32nm process and with over 460 million transistors, Piton is one of the largest and most complex academic processors every built. The Princeton team has opened their design up and released all of the chip source code, tests, and infrastructure as open source in the OpenPiton project, enabling others to build scalable, manycore processors with potentially thousands of cores.

An anonymous Slashdot reader quotes a report from fossBytes: Linux Mint 18 'Sarah' KDE Edition Beta is now available for download and testing. This release is based on the long-term supported Linux 4.4 kernel and KDE Plasma 5.6 desktop environment. The final release of this widely popular distro is expected to arrive in September... Just like MATE, Cinnamon, and Xfce releases, the KDE release is a long term release that will remain supported until 2021.

Linux Mint 18 'Sarah' KDE Edition ships with Mozilla Firefox as default web browser and LibreOffice as the default office suite. The Linux distro also features a wide range of popular KDE apps like Kontact, Dolphin, Gwenview, KMail, digiKam, KTorrent, Skanlite, Konversation, K3b, Konsole, Amarok, Ark, Kate, Okular, and Dragon Player.
"Unlike other Linux Mint editions, the KDE edition will ship with the SDDM display manager," reports the Linux Mint blog. Distrowatch notes that it's based on Ubuntu 16.04, and suggests "Mint's 'KDE' flavour might turn out to be the most interesting of the bunch, especially if the project's usually excellent quality assurance is applied to this edition in the same manner as in its 'MATE' and 'Cinnamon' variants."

An anonymous reader writes: Fedora 25 will finally be the first release for this Linux distribution -- and the first tier-one desktop Linux OS at large -- that is going ahead and using Wayland by default. Wayland has been talked about for years as a replacement to the xorg-server and finally with the upcoming Fedora 25 release this is expected to become a reality. The X.Org Server will still be present on Fedora systems for those running into driver problems or other common issues.
Fedora's steering committee agreed to the change provided the release notes "are clear about how to switch back to X11 if needed." In addition, according to the Fedora Project's wiki, "The code will automatically fall back to Xorg in cases where Wayland is unavailable (like NVIDIA)."

Microsoft announced on Thursday that it is open sourcing PowerShell, its system administration, scripting, and configuration management tool that has been a default part of Windows for several years. The company says it will soon release PowerShell on Mac and Linux platforms. PCWorld reports: The company is also releasing alpha versions of PowerShell for Linux (specifically Ubuntu, Centos and Redhat) and Mac OS X. A new PowerShell GitHub page gives people the ability to download binaries of the software, as well as access to the app's source code. PowerShell on Linux and Mac will let people who have already built proficiency with Microsoft's scripting language take those skills and bring them to new platforms. Meanwhile, people who are used to working on those platforms will have access to a new and very powerful tool for getting work done. It's part of Microsoft's ongoing moves to open up products that the company has previously kept locked to platforms that it owned. The company's open sourcing of its .NET programming frameworks in 2014 paved the way for this launch, by making the building blocks of PowerShell available on Linux and OS X. By making PowerShell available on Linux, Microsoft has taken the skills of Windows administrators who are already used to the software, and made them more marketable. It has also made it possible for hardcore Linux users to get access to an additional set of tools that they can use to manage a variety of systems.

"The first release candidate for the upcoming FreeBSD 11.0 is ready for testing," reports Distrowatch, noting various changes. ("A NULL pointer dereference in IPSEC has been fixed; support for SSH protocol 1 has been removed; OpenSSH DSA keys have been disabled by default...") Now an anonymous Slashdot reader writes: Sunday Phoronix performed some early benchmark testing, comparing FreeBSD 10.3 to FreeBSD 11.0 as well as DragonFlyBSD, Ubuntu, Intel Clear Linux and CentOS Linux 7. They reported mixed results -- some wins and some losses for FreeBSD -- using a clean install with the default package/settings on the x86_64/amd64 version for each operating system.

FreeBSD 11.0 showed the fastest compile times, and "With the SQLite benchmark, the BSDs came out ahead of Linux [and] trailed slightly behind DragonFlyBSD 4.6 with HAMMER. The 11.0-BETA4 performance does appear to regress slightly for SQLite compared to FreeBSD 10.3... With the BLAKE2 crypto test, all four Linux distributions were faster than DragonFlyBSD and FreeBSD... with the Apache web server benchmark, FreeBSD was able to outperform the Linux distributions..."

An anonymous reader quotes The Verge: GoldenEye: Source received its first update in more than three years this week. It's free to download and it features 25 recreated maps, 10 different multiplayer modes, and redesigned versions of the original game's 28 weapons. It was created using Valve's Source engine, the same set of tools used to create Counter Strike and Half-Life games. So it's a massive step up in both visuals and performance for one of the more drastically dated gaming masterpieces of the last 20 years...

GoldenEye 007, the beloved N64 first-person shooter, has been recreated in high-definition glory by a team of dedicated fans over the course of 10 years...the attention to detail and the amount of effort that went into GoldenEye: Source make it one of the most polished HD remakes of a N64 classic.
With 8 million copies sold, Wikipedia calls it the third best-selling Nintendo 64 game of all-time (although this version doesn't recreate its single-player campaigns). Anyone have fond memories of playing Goldeneye 007?

VLC remains one of the most popular applications. First released over 15 years ago, VLC is open-source, and is available across multiple platforms including Windows, OS X, Linux, Android, ChromeOS, iOS, and it's coming to the Xbox One later this year. We thought it would be great to have Jean-Baptiste Kempf, President of VideoLAN non-profit organization (the maker of VLC media player). In addition, he is also a lead developer of VLC.
