Orome1 writes with a snippet from a report at net-security.org; a hacker going by Hephaestos has shared with the world a Python script that, when put on an USB thumb drive, turns the device in an effective kill switch for the computer to which it's plugged in. USBkill, as the programmer dubbed it, "waits for a change on your USB ports, then immediately kills your computer." The device would be useful "in case the police comes busting in, or steals your laptop from you when you are at a public library," Hephaestos explained.
eldavojohn writes: A recent paper published in the Proceedings of the National Academy of Sciences turned up 2-Butoxyethanol from samples collected from three households in Pennsylvania. The paper's level headed conclusion is that more conservative well construction techniques should be used to avoid this in the future and that flowback should be better controlled. Rob Jackson, another scientist who reviewed the paper, stressed that the findings were an exception to normal operations. Despite that, the results angered the PR gods of the Marcellus Shale Gas industry and awoke beltway insider mouthpieces to attack the research — after all, what are they paying them for?
An anonymous reader writes: For over 5 years, and perhaps even longer, servers around the world running Linux and FreeBSD operating systems have been targeted by an individual or group that compromised them via a backdoor Trojan, then made them send out spam, ESET researchers have found. What's more, it seems that the spammers are connected with a software company called Yellsoft, which sells DirectMailer, a "system for automated e-mail distribution" that allows users to send out anonymous email in bulk. Here's the white paper in which the researchers explain the exploit.
An anonymous reader writes: The high-resolution images, taken by the New Solar Telescope (NST), show the atmosphere above the umbrae (the dark patches in the center of sunspots) to be finely structured, consisting of hot plasma intermixed with cool plasma jets as wide as 100 kilometers. These ground breaking images are being captured by scientists at NJIT's Big Bear Solar Observatory (BBSO). Sunspots are formed when strong magnetic fields rise up from the convection zone, a region beneath the photosphere that transfers energy from the interior of the Sun to its surface. At the surface, the magnetic fields concentrate into bundles, which prevent the hot rising plasma from reaching the surface. This energy deficit causes the magnetic bundles to cool down to temperatures about 1,000 degrees lower than their surroundings. The NST takes snapshots of the Sun every 10 seconds, which are then strung together as a video to reveal fast-evolving small explosions, plasma flows and the movement of magnetic fields.
jrepin writes: The KDE community has released Plasma 5.3, a major new version of the popular, open source desktop environment. The latest release brings much enhanced power management, better support for Bluetooth, and improved Plasma widgets. Also available is a technical preview of Plasma Media Center shell. In addition, Plasma 5.3 represents a big step towards support for the Wayland windowing system. There are also a few other minor tweaks and over 300 bugfixes. Here is the full changelog, and here's the package download wiki page.
An anonymous reader writes: A group of researchers from University of Washington have tested the security of a teleoperated robotic surgery system created by their colleagues, and have found it severely lacking. "Teleoperated surgical robots will be expected to use a combination of existing publicly available networks and temporary ad-hoc wireless and satellite networks to send video, audio and other sensory information between surgeons and remote robots. It is envisioned these systems will be used to provide immediate medical relief in under-developed rural terrains, areas of natural and human-caused disasters, and in battlefield scenarios," the researchers noted, and asked: "But what if these robotic systems are attacked and compromised?"
An anonymous reader writes: The first release candidate of Linux 4.1 is now available. Linus noted, "The merge window is pretty normal in terms of what got merged too. Just eyeballing the size, it looks like this is going to fit right in — while 4.0 was a bit smaller than usual, 4.1 seems to be smack dab in the middle of the normal range for the last couple of years." There are numerous new features in Linux 4.1, like Xbox One controller force feedback support, better Wacom tablet support, Intel Atom SoC performance improvements, Radeon DisplayPort MST support, EXT4 file-system encryption, ChromeOS Lightbar support, and ACPI for 64-bit ARM, among other additions. However, KDBUS wasn't accepted for Linux 4.1.
An anonymous reader writes: Earlier this week during Facebook's 2015 Q1 earnings call, the company seemed to suggest that a 2015 Oculus Rift release date was unlikely. At least, that's what a report about the call from Gamasutra indicated, saying, "It doesn't sound like Oculus will ship the consumer version of its Oculus Rift VR headset this year, or at least not in very large quantities." However, an equity analyst has chimed in to say that the language used during the call shouldn't be interpreted colloquially, concluding that "...there is no information here that rules out Oculus shipping in 2015."
jones_supa writes: Qt Creator 3.4.0 has been released with many new features. Qt Creator is a C/C++ IDE with specialized tools for developing Qt applications, and it works great for general-purpose projects as well. The new version comes with a C++ refactoring option to move function definitions out of a class declaration, auto-completion for signals and slots in Qt5-style connects, experimental Qt Test and Qt Quick Tests support in the Professional and Enterprise edition, support for 64-bit Android toolchains, and various other improvements. More details on the new version can be found in the official announcement and the changelog.
Team 116 at Herndon High School in Virginia. He's here to tell us about the new embedded Linux controller FIRST is using this year. It is apparently a bit short of documentation at this stage, so team 116 and others have been posting what they learn at Chief Delphi, which is 'the' FIRST online discussion forum (and fun to read to keep up with all things FIRST). We've talked about FIRST before. We've taken you to FIRST competitions, and looked behind the scenes at the building of a FIRST robot, and will no doubt keep covering a selection of FIRST activities in the future.
An anonymous reader writes: AMD has made available its new AMDGPU Linux graphics driver comprised of a brand new DRM/KMS kernel driver, a new xf86-video-amdgpu X11 driver, and modifications to libdrm and Gallium3D. This new AMDGPU driver is designed for supporting AMD's next-generation hardware with no support differences for currently supported Radeon GPUs. While yet to be released, this new AMDGPU driver is the critical piece to the new unified driver strategy with Catalyst where their high performance proprietary driver will now become limited to being a user-space binary component that uses this open-source kernel driver.
An anonymous reader writes "After nearly two years of waiting for Mojang to fix a security vulnerability that can be used to crash Minecraft servers, programmer Ammar Askar has released a proof of concept exploit for the flaw in the hopes that this will force them to do something about it. "Mojang is no longer a small indie company making a little indie game, their software is used by thousands of servers, hundreds of thousands people play on servers running their software at any given time. They have a responsibility to fix and properly work out problems like this," he noted." Here is Askar's own post on the exploit, and his frustration with the response he's gotten to disclosing it to the developers.
jones_supa writes: The KDE project today announced the release of KDE Plasma 5.3 beta. It brings better power management, improved Bluetooth support, improved widgets, Wayland support, new media center, and nearly 350 bugfixes. The power management improvements include settings that can be independently configured per activity, there is a new energy usage monitor available in KInfoCenter, and a battery applet identifies applications that hog power. Bluetooth applet brings added support for blocking and unblocking devices. New touchpad module has been added as well. The combined window manager and compositor KWin is now able to start a nested XWayland server, which acts as a bridge between the old X11 and the new Wayland world.
An anonymous reader writes: The Nouveau driver developers working on open-source support for the GeForce 900 Maxwell graphics cards have found this new generation to be "very open-source unfriendly" and restricting. NVIDIA began requiring signed firmware images, which they have yet to provide to Nouveau developers, contrary to their earlier statements. The open-source developers have also found their firmware signing to go beyond just simple security precautions. For now the open-source NVIDIA driver can only enable displays with the GTX 900 series without any hardware acceleration.
192_kbps writes: NASA published today the first color image of Pluto and Charon captured by the New Horizons probe, revealing a reddish world. "The fastest spacecraft ever launched, New Horizons has traveled a longer time and farther away - more than nine years and three billion miles - than any space mission in history to reach its primary target. Its flyby of Pluto and its system of at least five moons on July 14 will complete the initial reconnaissance of the classical solar system. This mission also opens the door to an entirely new "third" zone of mysterious small planets and planetary building blocks in the Kuiper Belt, a large area with numerous objects beyond Neptune's orbit." The picture is blurry, but far better than the few pixels Hubble can resolve, the image whets the appetite for New Horizon's closest approach on July 14th."
An anonymous reader writes Are the days of Microsoft's proprietary compiler over? Microsoft has announced they've started work on a new .NET compiler using LLVM and targets their CoreCLR — any C# program written for the .NET core class libraries can now run on any OS where CoreCLR and LLVM are supported. Right now the compiler only supports JIT compilation but AOT is being worked on along with other features. The new Microsoft LLVM compiler is called LLILC and is MIT-licensed.
jones_supa writes: A massive x86 assembly code spring cleaning has been done in a pull request that is to end up in Linux 4.1. The developers have tried testing the code on many different x86 boxes, but there's risk of regression when exposing the code to many more systems in the days and weeks ahead. That being said, the list of improvements is excellent. There are over 100 separate cleanups, restructuring changes, speedups and fixes in the x86 system call, IRQ, trap and other entry code, part of a heroic effort to deobfuscate a decade old spaghetti assembly code and its C code dependencies.
An anonymous reader writes "The Linux 4.0 kernel has been released. Linux 4.0 brings many features including live patching, Radeon DisplayPort Audio, RadeonSI fan control improvements, new OverlayFS functionality, Intel Quark SoC support, and a heck of a lot more. Linus's release announcement reads in part: "So I decided to release 4.0 as per the normal schedule, because there really weren't any known issues, and while I'll be traveling during the end of the upcoming week due to a college visit, I'm hoping that won't affect the merge window very much. We'll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously 'small' is all relative. It's still over 10k non-merge commits. But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones)."
StartsWithABang writes: The accelerated expansion of the Universe — and hence, dark energy — was discovered by taking the well-understood phenomenon of type Ia supernovae and measuring them out to great distances. The results indicated that they were fainter than expected, and hence more distant, and hence the Universe's expansion must be accelerating. But new results have just come out, showing that supernovae may not be standard after all. Does this mean dark energy may not be real, or that it may just be slightly weaker than we previously thought?
