An anonymous reader writes "Linus Torvalds has sent a lengthy statement to Ars Technica responding to statements he made in a conference in New Zealand. One of his classic comments in NZ was: "I'm not a nice person, and I don't care about you. I care about the technology and the kernel — that's what's important to me." On diversity, he said that "the most important part of open source is that people are allowed to do what they are good at" and "all that stuff is just details and not really important." Now he writes: "What I wanted to say — and clearly must have done very badly — is that one of the great things about open source is exactly the fact that different people are so different", and that "I don't know where you happen to be based, but this 'you have to be nice' seems to be very popular in the US," calling the concept of being nice an "ideology"."

An anonymous reader writes: Tests of the AMD Catalyst driver with the latest AAA Linux games/engines have shown what poor shape the proprietary Radeon driver currently is in for Linux gamers. Phoronix, which traditionally benchmarks with open-source OpenGL games and other long-standing tests, recently has taken specially interest in adapting some newer Steam-based titles for automated benchmarking. With last month's Linux release of Metro Last Light Redux and Metro 2033 Redux, NVIDIA's driver did great while AMD Catalyst was miserable. Catalyst 14.12 delivered extremely low performance and some major bottleneck with the Radeon R9 290 and other GPUs running slower than NVIDIA's midrange hardware. In Unreal Engine 4 Linux tests, the NVIDIA driver again was flawless but the same couldn't be said for AMD. Catalyst 14.12 wouldn't even run the Unreal Engine 4 demos on Linux with their latest generation hardware but only with the HD 6000 series. Tests last month also showed AMD's performance to be crippling for NVIDIA vs. AMD Civilization: Beyond Earth Linux benchmarks with the newest drivers.

An anonymous reader sends a report of a bug in Steam's Linux client that will accidentally wipe all of a user's files if they move their Steam folder. According to the bug report: I launched steam. It did not launch, it offered to let me browse, and still could not find it when I pointed to the new location. Steam crashed. I restarted it. It re-installed itself and everything looked great. Until I looked and saw that steam had apparently deleted everything owned by my user recursively from the root directory. Including my 3tb external drive I back everything up to that was mounted under /media. Another user reported a similar problem — losing his home directory — and problems with the script were found: at some point, the Steam script sets $STEAMROOT as the directory containing all Steam's data, then runs rm -rf "$STEAMROOT/"* later on. If Steam has been moved, $STEAMROOT returns as empty, resulting in rm -rf "/"* which causes the unexpected deletion.

Even Red Hat wasn't keen on it at the start, but since then it has worked its way into almost every major distro. Linux Voice talks to Lennart Poettering, the lead developer of Systemd, about its origins, its future, its relationship with Upstart, and handling the pressures of online flamewars.

An anonymous reader writes I'm in the camp that doesn't trust systemd. You can discuss the technical merits of all init solutions all you want, but if I wanted to run Windows NT I'd run Windows NT, not Linux. So I've decided to migrate my homebrew router/firewall/samba server to one of the BSDs. Question one is: which BSD? Question two: where's some good documentation regarding setting up a home router/firewall on your favorite BSD?
It's fine if the documentation is highly technical, I've written linux kernel drivers before :)

jones_supa writes A lot of development work is happening on systemd with just the recent couple of weeks seeing over 200 commits. With the most recent work that has landed, the networkd component has been improved with new features. Among the additions are IP forwarding and masquerading support (patch). This is the minimal support needed and these settings get turned on by default for container network interfaces. Also added was minimal firewall manipulation helpers for systemd's networkd. The firewall manipulation helpers (patch) are used for establishing NAT rules. This support in systemd is provided by libiptc, the library used for communicating with the Linux kernel's Netfilter and changing iptables firewall rulesets. Those wishing to follow systemd development on a daily basis and see what is actually happening under the hood, can keep tabs via the systemd Git viewer.

DeviceGuru writes CompuLab has unveiled a tiny 'Fitlet' mini-PC that runs Linux or Windows on a dual- or quad-core 64-bit AMD x86 SoC (with integrated Radeon R3 or R2 GPU), clocked at up to 1.6GHz, and offering extensive I/O, along with modular internal expansion options. The rugged, reconfigurable 4.25 x 3.25 x 0.95 in. system will also form the basis of a pre-configured 'MintBox Mini' model, available in Q2 in partnership with the Linux Mint project. To put things in perspective, CompuLab says the Fitlet is three times smaller than the Celeron Intel NUC.

New submitter msubieta writes I have been developing some applications to use in small businesses using Windows and SQL Server. I would like to move on and start doing the same thing in Linux. I have looked at several Frameworks/Databases/Development environments and I really don't know what is the best/simplest/fastest to learn approach. I use VS and C# mostly, although I could easily go back to C++. I found Qt and GTK+ are the most common frameworks, but they seem to lack controls that deal with datasets and stuff (sorry, spoiled by the .net form controls), but I also know that I could use Mono in order to make the jump. I would have no problem on moving to MySQL, as I have done quite a lot of work on that side, and I would like to stick with the traditional client server application, as I find it easier to maintain, and a whole lot more robust when it comes to user interaction (web apps for POS applications don't seem to be the right way to go in my view). Any suggestions/comments/recommendations?

Now, a few months after the magazine made issue 1 freely available, they've released issue 2 under the Creative Commons for everyone to share and modify. If you've ever fancied making your own Raspberry Pi-powered arcade machine, there's a full guide in the second issue.

An anonymous reader writes: Red Star OS Desktop 3.0, the official Linux distro of North Korea, which recently found its way onto torrents and various download sites in form of an ISO image, is interesting for a number of reasons, including its attempt to look like commercial operating systems (currently OS X, earlier versions mimicked the Windows GUI). Hackers are also poking Red Star for security vulnerabilities. An pseudonymous researcher noted in a post to the Open Source Software Security (oss-sec) mailing list, that the OS has one significant security hole: Red Star 3.0 ships with a world-writeable udev rule file /etc/udev/rules.d/85-hplj10xx.rules (originally designed for HP LaserJet 1000 series printers) which can be modified to include RUN+= arguments executing arbitrary commands as root by Udev. In the post he also mentions how the older Red Star 2.0 shipped with another schoolboy mistake: /etc/rc.d/rc.sysinit was world-writeable.

jones_supa writes: Network World's analysis of publicly listed sponsors of 36 prominent open-source non-profits and foundations reveals that the lion's share of financial support for open-source groups comes from a familiar set of names. Google was the biggest supporter, appearing on the sponsor lists of eight of the 36 groups analyzed. Four companies – Canonical, SUSE, HP and VMware – supported five groups each, and seven others (Nokia, Oracle, Cisco, IBM, Dell, Intel and NEC) supported four. For its part, Red Hat supports three groups (Linux Foundation, Creative Commons and the Open Virtualization Alliance).

It's tough to get more than a general sense of how much money gets contributed to which foundations by which companies – however, the numbers aren't large by the standards of the big contributors. The average annual revenue for the open-source organizations considered in the analysis was $4.36 million, and that number was skewed by the $27 million taken in by the Wikimedia Foundation (whose interests range far beyond OSS development) and the $17 million posted by Linux Foundation.

jones_supa writes: Dave Jones from Red Hat has written a wrap-up of the strange bug that has made some machines running Linux to freeze. (Previous discussion.) Right down to his final week at Red Hat before Dave gave all his hardware back, Linus Torvalds managed to reproduce similar symptoms, by scribbling directly to the HPET timer. He came up with a hack that at least made the kernel survive for him. When Dave tried the same patch, the machine ran for three days before he interrupted it, which was a promising result. The question remains, what was scribbling over the HPET in his case? The only two plausible scenarios Dave could think of were that Trinity generated 0xFED000F0 as a random address and passed that to a syscall which wrote to it, or a hardware bug. That's where the story ends for now. Linus' hacky workaround didn't get committed, but him and John Stultz continue to back and forth on hardening the clock management code in the face of screwed up hardware, so maybe soon we'll see something real get committed on that area.

jones_supa writes: As you may have heard, the NSA has had some success in cracking Secure Shell (SSH) connections. To respond to these risks, a guide written by Stribika tries to help you make your shell as robust as possible. The two main concepts are to make the crypto harder and make stealing keys impossible. So prepare a cup of coffee and read the tutorial carefully to see what could be improved in your configuration. Stribika gives also some extra security tips: don't install what you don't need (as any code line can introduce a bug), use the kind of open source code that has actually been reviewed, keep your software up to date, and use exploit mitigation technologies.

jones_supa writes: After nearly two years since the previous release, the Fluxbox team has released version 1.3.6 to start off the new year. Like most Linux geeks already know, Fluxbox is the long-standing X window manager derived from Blackbox. The new version (announcement) puts emphasis on quality assurance and takes care of fixing a bunch of critical bugs: clocktool problems, rendering long text, race condition on shutdown, lost keypresses after workspace switch, corruption of fbrun-history, and resize and move problems. The two new features are an ArrangeWindowsStack action and treating Windows with a WM_CLASS as DockApp as DockApps. Translations for Bulgarian, Hebrew and Japanese also got updates. The Fluxbox project sends many thanks to all the contributors.

Steve Parrish writes: I needed a new laptop and found a great deal on an Asus Transformer TP500L. It's one of the laptops where you can flip the screen back and use it as a tablet. I'd like to replace Windows 8.1, and I'm having a difficult time finding a Linux distro that will work on it. I'm familiar with Mint, SolydX, and older Ubuntu versions. I tried the latest Ubuntu with Unity and didn't like it, but the OS installed with only a few minor issues. Has anyone tried any other distros on a hybrid laptop with a touchscreen? I've used Linux for several years, but I'm no guru -- I'm not comfortable with the command line or other advanced workings. Any suggestions would be appreciated.

An anonymous reader writes: Along with the open-source AMD Linux driver having a great 2014, the AMD Catalyst proprietary driver for Linux has also improved a lot. Beyond the open-source Radeon Gallium3D driver closing in on Catalyst, the latest Phoronix end-of-year tests show the AMD Catalyst Linux driver is beating Catalyst on Windows for some OpenGL benchmarks. The proprietary driver tests were done with the new Catalyst "OMEGA" driver. Is AMD beginning to lead real Linux driver innovations or is OpenGL on Windows just struggling?

jones_supa writes: Siddhesh Poyarekar from Red Hat has taken a professional look into mathematical functions found in Glibc (the GNU C library). He has been able to provide an 8-times performance improvement to slowest path of pow() function. Other transcendentals got similar improvements since the fixes were mostly in the generic multiple precision code. These improvements already went into glibc-2.18 upstream. Siddhesh believes that a lot of the low hanging fruit has now been picked, but that this is definitely not the end of the road for improvements in the multiple precision performance. There are other more complicated improvements, like the limitation of worst case precision for exp() and log() functions, based on the results of the paper Worst Cases for Correct Rounding of the Elementary Functions in Double Precision (PDF). One needs to prove that those results apply to the Glibc multiple precision bits.

jfruh writes Heartbleed, Shellshock, Poodle — all high-profile vulnerabilities in widely used libraries that rocked the software industry in 2014. Sadly, experts are now beginning to believe that these aren't the only bugs lurking out there in widely used open source code, just the ones that grabbed the most attention. It's beginning to look like one of the foundation concepts of open source — that with enough eyes, all bugs are shallow — is a myth. Of course, probably no one believes that all bugs are instantly shallow, no matter how open is the source, or that open source software is immune from bugs -- particularly ESR, coiner of the phrase.
