UEFI Secure Boot Pre-Bootloader Rewritten To Boot All Linux Versions 185

hypnosec writes "The Linux Foundation's UEFI secure boot pre-bootloader is still in the works, and has been modified substantially so that it allows any Linux version to boot through UEFI secure boot. The reason for modifying the pre-bootloader was that the current version of the loader wouldn't work with Gummiboot, which was designed to boot kernels using BootServices->LoadImage(). Further, the original pre-bootloader had been written using 'PE/Coff link loading to defeat the secure boot checks.' As it stands, anything run by the original pre-bootloader must also be link-loaded to defeat secure boot, and Gummiboot, which is not a link-loader, didn't work in this scenario. This is the reason a re-write of the pre-bootloader was required and now it supports booting of all versions of Linux." Also in UEFI news: Linus Torvalds announced today that the flaw which was bricking some Samsung laptops if booted into Linux has been dealt with.

Linux: Booting Via UEFI Can Brick Samsung Notebooks 232

wehe writes "Heise News reports today some Samsung notebooks can be turned into a brick if booted just one time via UEFI into Linux. Even the firmware does not boot anymore. Some reports in the Ubuntu bug tracker system report that such notebooks can not be recovered without replacing the main board. Other Linux distributions may be affected as well. Kernel developers are discussing a change in the Samsung-laptop driver." It appears even Samsung is having trouble tracking down the problem (from the article): "According to Canonical's Steve Langasek, Samsung developers have been attempting to develop a firmware update to prevent the problem for several weeks. Langasek is advising users to start Ubuntu installation on Samsung notebooks from an up-to-date daily image, in which the Ubuntu development team has taken precautions to prevent the problem from arising. It is, however, not completely clear that these measures are sufficient."

Ask Slashdot: Open Source Remote Application Access? 113

First time accepted submitter taikedz writes "Citrix Xenapp with Receiver/Metaframe allows publishing individual applications installed on a Windows server to users on remote machines. These applications open in their own windows, along side others as if they were installed locally. I am looking to do the same at home, with free software, publishing applications from Mac, Linux, and Windows machines (and yes, I've verified the license agreements for the apps I am going to do this with!). Up until now, the only alternatives I have found are full-on remote desktop login, not seamlessly-integrated. Can you recommend any tools that can achieve the goal of remote individual application access across platforms for free or at low-cost?"
Bug

New Secure Boot Patches Break Hibernation 196

hypnosec writes "Matthew Garrett published some patches today which break hibernate and kexec support on Linux when Secure Boot is used. The reason for disabling hibernation is that currently the Linux kernel doesn't have the capability of verifying the resume image when returning from hibernation, which compromises the Secure Boot trust model. The reason for disabling the kexec support while running in Secure Boot is that the kernel execution mechanism may be used to load a modified kernel thus bypassing the trust model of Secure Boot." Before arming your tactical nuclear flame cannon, note that mjg says "These patches break functionality that people rely on without providing any functional equivalent, so I'm not suggesting that they be merged as-is." Support for signed kexec should come eventually, but it looks like hibernation will require some clever hacking to support properly in a Restricted Boot environment.

Video LinuxFest Northwest is Coming in April (Video) 43

Jakob Perry, today's interviewee, is a volunteer who helps make LinuxFest Northwest happen. This is an event produced by the Bellingham Linux Users Group that "has been a tradition in Bellingham, WA since 2000." Bellingham is a small town about a 1.5 hour drive away from Seattle, and a shorter distance from Vancouver, Canada. Last year they had 1200 people. They have a core group of about 10 year-round volunteers, with as many as 60 participating in the event itself, many of whom are students at Bellingham Technical College, which is where LinuxFest Northwest is held.

Why a Linux User Is Using Windows 3.1 415

colinneagle writes "About two weeks back, I was using my Android tablet and looking for a good graphics editor. I wanted something with layers and good text drawing tools. That's when it hit me. We already have that. Photoshop used to run on Windows 3.1. And Windows 3.1 runs great under both DOSBox and QEMU, both of which are Open Source emulators available for Android and every other platform under the sun. So I promptly set to work digging up an old copy of Photoshop. The last version released for Windows 3.1 was back in 1996. And finding a working copy proved to be...challenging. Luckily, the good folks at Adobe dug around in their vaults and managed to get me up and running. And, after a bit of tweaking, I ended up with an astoundingly functional copy of Photoshop that I can now run on absolutely every device I own. And the entire environment (fonts, working files and all) are automatically backed up to the cloud and synced between systems. But what other applications (and, potentially, games) does this give me access to? How far can I take this?"

"Adults Only" OpenArena Now Playable On Raspberry Pi 65

hypnosec writes "The Raspberry Pi Foundation has released OpenArena – a multiplayer first person shooter game based on Quake III — for the Raspberry Pi. Available as a free download, the game has been rated 'Adults Only' because of the blood and guns. The open-source game is powered by the 'ioquake3' fork of the engine that Quake III runs on id's Tech 3 engine. Modifications have been made to the gameplay by removing the copyrighted material and adding new free content."

Alan Cox Exits Intel, Linux Development 214

judgecorp writes "Linux kernel developer Alan Cox has left Intel and Linux development after slamming the Fedora 18 distribution. He made the announcement on Google+ and promised that he had not fallen out with Linus Torvalds, and would finish up all outstanding work." Also at Live Mint, which calls Cox's resignation notice a "welcome change from the sterility, plain dishonesty of CEO departure statements." Cox says in that statement that he's leaving "for a bit," and "I may be back at some point in the future - who knows."

Cox posted comments to his Google+ page saying 'Fedora 18 seems to be the worst Red Hat distro I've ever seen.' He encountered numerous problems with Fedora 18 and then decided to switch to Ubuntu."

Open Source ExFAT File System Reaches 1.0 Status 151

Titus Andronicus writes "fuse-exfat, a GPLv3 implementation of the exFAT file system for Linux, FreeBSD, and OS X, has reached 1.0 status, according to an announcement from Andrew Nayenko, the primary developer. exFAT is a file system designed for sneaker-netting terabyte-scale files and groups of files on flash drives and memory cards between and among Windows, OS X, and consumer electronics devices. It was introduced by Microsoft in late 2006. Will fuse-exfat cut into Microsoft's juicy exFAT licensing revenue? Will Microsoft litigate fuse-exfat's developers and users into patent oblivion? Will there be a DKMS dynamic kernel module version of the software, similar to the ZFS on Linux project? All that remains to be seen. ReadWrite, The H, and Phoronix cover the story."

The Road To KDE Frameworks 5 and Plasma 2 89

jrepin wrote in with a link to an article about the steps being taken toward a Qt5 based KDE 5 and Plasma Workspaces 2. From the article: "KDE's Next Generation user interfaces will run on top of Qt5. On Linux, they will run atop Wayland or Xorg as display server. The user interfaces move away from widget-based X11 rendering to OpenGL. Monolithic libraries are being split up, inter-dependencies removed, and portability and dependencies cut by stronger modularization. For users, this means higher quality graphics, more organic user interfaces and availability of applications on a wider range of devices. Developers will find an extensive archive of high-quality, libraries and solutions on top of Qt."

Arch GNU/Linux Ported To Run On the FreeBSD Kernel 79

An anonymous reader writes "The Arch Linux distribution has been modified to run off the FreeBSD 9.0 kernel as an alternative to using Linux. The developer of Arch BSD explained his reasoning as enjoying FreeBSD while also liking the Arch Linux philosophy of a 'fast, lightweight, optimized distro,' so he sought to combine the two operating systems to have FreeBSD at its core while being encircled by Arch. The Arch BSD initiative is similar to Debian GNU/kFreeBSD."

LTSI Linux Kernel 3.4 Released 61

hypnosec writes "The Linux Foundation has announced the release of Linux 3.4 under its Long Term Support Initiative (LTSI), which will be maintained for the next two years with back-ported features from newer Linux kernels. Based on Linux 3.4.25, the LTSI 3.4 is equipped with features such as Contiguous Memory Allocator – which is helpful for embedded devices with limited hardware resource availability; AF_BUS – a kernel-based implementation of the D-Bus protocol; and CoDel (controlled delay) – a transmission algorithm meant for optimization of TCP/IP network buffer control."

Canonical Could Switch To Rolling Releases For Ubuntu 14.04 and Beyond 222

massivepanic writes "For the longest time Canonical has slapped an LTS ("long term support") moniker on some of their Ubuntu releases. Currently, a new major release of the operating system happens every six months, and is supported for 18 months after release. Whereas in the past when LTS versions received two years support or more, the current model — starting with 12.04 — supports new LTS releases for five years. However, a recent public Google Hangouts session revealed that Canonical has been thinking about switching from the venerable LTS model to a rolling release, starting with version 14.04."

MS Won't Release Study Disputing Munich's Linux-Switch Savings 268

itwbennett writes "As previously reported on Slashdot, in November of last year, the city of Munich reported savings of over €10 million from its switch to Linux. Microsoft subsequently commissioned a study (conducted by HP) that found that, in fact, 'Munich would have saved €43.7 million if it had stuck with Microsoft.' Now, Microsoft has said it won't release the study, saying that '[it] was commissioned by Microsoft to HP Consulting for internal purposes only.'"

Ask Slashdot: Best Webcam To Augment Impaired Vision? 63

mynamestolen writes "In order to read paper-based books many visually impaired people want to attach a webcam to a computer and attach the computer to a TV. Some Electronic Magnifiers are purpose-built to provide a similar solution. Different organisations around the world (such as in the UK) have help pages. But I have not been able to find a guide to set up my own system. So I'm asking Slashdot readers how to go about it. What is the best camera to use if I want to hold the camera in my hand and point it at book or magazine? What parameters should I adjust, either in the software or on the camera? Depth of view, refresh rates, contrast, color balance and resolution might be key problems. My system is Linux and getting drivers for a good camera might also be a problem."

Fedora 19 Nixing MySQL in Favor of MariaDB 116

An anonymous reader writes "Red Hat developers are planning to replace MySQL with MariaDB in Fedora 19. For the next Fedora update, the MariaDB fork would replace MySQL and the official MySQL package would be discontinued after some time. The reasoning for this move is the uncertainty about Oracle's support of MySQL as an open-source project and moves to make the database more closed." Update: 01/22 13:47 GMT by T : Note: "Nixing" may be a bit strong; this move has been proposed, but is not yet officially decided.

Fedora 18 Installer: Counterintuitive and Confusing? 458

An anonymous reader writes "Igor Ljubuncic, former physicist and current IT Systems Programmer and blogger, reviews Fedora 18 with its new installer. In his role as alter ego Dedoimedo, the self proclaimed 'king of everything', Igor's Linux distro and DE reviews are often wry and biting and this review is no exception: 'You enter a world of smartphone-like diarrhea that undermines everything and anything that is sane and safe. In all my life testing Linux and other operating systems, I have never ever seen an installer that is so counter-intuitive, dangerous and useless, all at the same time.'" The non-linear installer interface does look like kind of confusing, at least from the screenshots posted.
