AMD's R9 Fury On Open-Source: Prepare for Disappointment, For Now 21

An anonymous reader writes: With Linux 4.3 AMD is adding the initial open-source driver for the R9 Fury graphics cards. Unfortunate for Linux gamers, the R9 Fury isn't yet in good shape on the open-source driver and it's not good with the Catalyst Linux driver either as previously discussed. With the initial code going into Linux 4.3, the $550 R9 Fury runs slower than graphics cards like the lower-cost and older R7 370 and HD 7950 GPUs, since AMD's open-source developers haven't yet found the time to implement power management / re-clocking support. The R9 Fury also only advertises OpenGL 3.0 support while the hardware is GL4.5-capable and the other open-source AMD GCN driver ships OpenGL 4.1. It doesn't look like AMD has any near-term R9 Fury Linux fix for either driver, but at least their older hardware is performing well with the open-source code.

Systemd Absorbs "su" Command Functionality 635

jones_supa writes: With a pull request systemd now supports a su command functional and can create privileged sessions that are fully isolated from the original session. The su command is seen as bad because what it is supposed to do is ambiguous. On one hand it's supposed to open a new session and change a number of execution context parameters, and on the other it's supposed to inherit a lot concepts from the originating session. Lennart Poettering's long story short: "`su` is really a broken concept. It will given you kind of a shell, and it's fine to use it for that, but it's not a full login, and shouldn't be mistaken for one." The replacement command provided by systemd is machinectl shell.

Ubuntu Is the Dominant Cloud OS 162

An anonymous reader writes: According to a new report by Cloud Market, Ubuntu is more than twice as popular on Amazon EC2 as all other operating systems combined. Given that Amazon Web Services has 57% of the public cloud market, Ubuntu is clearly the most popular OS for cloud systems. This is further bolstered by a recent OpenStack survey, which found that more than half of respondents used Ubuntu for cloud-based production environments. Centos was a distant second at 29%, and RHEL came in third at 11%. "In addition to AWS, Ubuntu has been available on HP Cloud, and Microsoft Azure since 2013. It's also now available on Google Cloud Platform, Fujitsu, and Joyent." The article concludes, "People still see Ubuntu as primarily a desktop operating system. It's not — and hasn't been for some time."

Happy Birthday, Linux! An OS At 24 152

prisoninmate writes: It has been 24 long years since the first ever release of the Linux project on August 25, 1991, which is the core component of any GNU/Linux distribution. With this occasion we want to remind everyone that Linux is everywhere, even if you don't see it. You use Linux when you search on Google, when you use your phone, when buy metro tickets, actually the whole Internet is powered by Linux. Happy Birthday, Linux!

Ubuntu Core Gets Support For Raspberry Pi 2 GPIO and I2C 57

An anonymous reader writes: Ubuntu Core is a tiny Ubuntu distribution aimed at the Internet of Things, using a new transactional packaging format called Snappy rather than the venerable Debian packaging format. It recently gained support for I2C and GPIO on the Raspberry Pi 2, and a quick demo is given here. Ubuntu's Core support site says that the support for Raspberry Pi 2 isn't yet official, but provides some handy tips for anyone who wants to try it out.

Meet Linux's Newest File-System: Bcachefs 131

An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data — but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.

City of Munich Struggling With Basic Linux Functionality 392

jones_supa writes: Just like the city planned a year ago, Munich is still calling for a switch back to Windows from LiMux, their Ubuntu derivative. The councilors from Munich's conservative CSU party have called the operating system installed on their laptops "cumbersome to use" and "of very limited use." The letter from the two senior members of the city's IT committee (PDF in German) asks the mayor to consider removing the Linux-based OS and to install Windows and Office. "There are no programs for text editing, Skype, Office etc. installed and that prevents normal use," the letter argues. Another complaint from councilors is that "the lack of user permissions makes them of limited use." These kind of arguments raise eyebrows, as all that functionality is certainly found on Linux.

Linux Foundation Project Will Evaluate Security of Open Source Software 37

An anonymous reader writes: The Core Infrastructure Initiative (CII), a project managed by The Linux Foundation, is developing a new free Badge Program, seeking input from the open source community on the criteria to be used to determine security, quality and stability of open source software. The first draft of the criteria is available on GitHub and is spearheaded by David A. Wheeler, an open source and security research expert who works for the Institute for Defense Analyses and is also coordinating the CII's Census Project, and Dan Kohn, a senior adviser on the CII.

Linus Torvalds Isn't Looking 10 Years Ahead For Linux and That's OK 108

darthcamaro writes: At the Linuxcon conference in Seattle today, Linus Torvalds responded to questions about Linux security and about the next 10 years of Linux. For security, Torvalds isn't too worried as he sees it just being about dealing with bugs. When it comes to having a roadmap he's not worried either as he just leaves that to others. "I'm a very plodding, pedestrian person and look only about six months ahead," Torvalds said. "I look at the current release and the next one, as I don't think planning 10 years ahead is sane."

Debian Founder: How I Came To Find Linux 136

An anonymous reader writes: Ian Murdock has pretty solid open source cred: in 1993 he founded Debian, he was the CTO of Progeny and the Linux Foundation, and he helped pave the way for OpenSolaris. He has published a post about how he initially joined the Linux ecosystem. Quoting: "[In 1992], I spent most evenings in the basement of the MATH building basking in the green phosphorescent glow of the Z-29 terminals, exploring every nook and cranny of the UNIX system upstairs. ... I was also accessing UNIX from home via my Intel 80286-based PC and a 2400-baud modem, which saved me the trek across campus to the computer lab on particularly cold days. Being able to get to the Sequent from home was great, but I wanted to replicate the experience of the ENAD building's X terminals, so one day, in January 1993, I set out to find an X server that would run on my PC. As I searched for such a thing on Usenet, I stumbled across something called 'Linux.'" How did you come to find Linux?

AMD Still Struggling With Linux Gaming 100

An anonymous reader writes: AMD's Linux gaming performance has been embarrassingly bad, and it doesn't look like there's any quick remedy. Virtual Programming just released Dirt: Showdown for Linux, and it's the latest example of AMD's Linux driver issues: AMD's GPU results are still far behind NVIDIA's, with even the Radeon R9 Fury running slower than NVIDIA's aging GTX 680 and GTX 760. If a racing game doesn't interest you, Feral Interactive confirmed they are releasing Company of Heroes 2 for Linux next week, but only NVIDIA and Intel graphics are supported.

"Father Time" Gets Another Year At NTP From Linux Foundation 157

dkatana writes: Harlan Stenn, Father Time to some and beleaguered maintainer of the Network Time Protocol (NTP) to others, will stay working for the NTP another year. But there is concern that support will decline as more people believe that NTP works just fine and doesn't need any supervision. NTP is the preeminent time synchronization system for Macs, Windows, and Linux computers and most servers on networks. According to IW, for the last three-and-a-half years, Stenn said he's worked 100-plus hours a week answering emails, accepting patches, rewriting patches to work across multiple operating systems, piecing together new releases, and administering the NTP mailing list. If NTP should get hacked or for some reason stop functioning, hundreds of thousands of systems would feel the consequences. "If that happened, all the critics would say, 'See, you can't trust open source code,'" said Stenn.
