The 2015 Linux hacker board survey has arrived. In its second year, this collaboration between Linux.com and LinuxGizmos.com has collected 53 open-spec, community backed SBCs that run Linux and/or Android. Please take a few minutes to fill out our short SurveyMonkey SBC Survey, and select your favorite SBCs, then enter a drawing to become one of 20 randomly chosen participants who receive a free Linux SBC. Farther below, we offer brief summaries of the 53 boards, with links to product pages.
Linux desktop users have two main sets of utilities: KDE's and GNOME's. The GNOME utilities are found in GNOME, MATE, Cinnamon and Unity. Neither KDE nor GNOME has any objective advantage over the other, but the user experiences are so different that they could almost be two different operating systems.
Both utility sets have the same basic features, but each starts with its own concept of what users want. As I have said before, GNOME's utilities are exercises in minimalism, generally designed only for the most common use cases. By contrast, KDE's utilities are completist, typically cramming every possibly related feature into their windows, as well as every possible opportunity for customization.
On May 20, Canonical published a new Ubuntu security notice where they've informed users about the immediate availability of a new kernel update for its Ubuntu 14.04 LTS (Trusty Tahr) operating system.
When TrackingPoint first showcased its Linux-powered scopes with tracking assistance that substantially improved rifle accuracy, even in the hands of untrained hunters, it kicked off a controversy over what level of technology was appropriate for hunting or home defense, and whether the company encouraged irresponsible behavior. Now, it seems that debate is coming to an end thanks to imminent financial failure. While the company’s website remains online for now, there’s a new header that notes: “Due to financial difficulty, TrackingPoint will no longer be accepting orders. Thank you to our customers and loyal followers for sharing our vision.”
Dan Berrange, creator of libvirt, sums it up nicely on the Fedora Devel list:
"While you might be able to crash the QEMU process associated with your own guest, you should not be able to escalate from there to take over the host, nor be able to compromise other guests on the same host. The attacker would need to find a second independent security flaw to let them escape SELinux in some manner, or some way to trick libvirt via its QEMU monitor connection. Nothing is guaranteed 100% foolproof, but in absence of other known bugs, sVirt provides good anti-venom for this flaw IMHO."
At the start of 2014, attackers' favorite distributed denial of service attack strategy was to send messages to misconfigured servers with a spoofed return address – the servers would keep trying to reply to those messages, allowing the attackers to magnify the impact of their traffic.
Another HTTPS vulnerability has started to make its rounds earlier this morning. Dubbed Logjam by its researchers, the vulnerability stems from the US's encryption export mandate back in the 1990s. This particular vulnerability, in the transport-layer security layer protocol, breaks the Diffie-Hellman perfect forward-secrecy. Susceptibility to the vulnerability is depended on servers and clients supporting the DHE_EXPORT encryption scheme, or using a key less-than-or-equal to 1024 bits.
Linux containers have been around for several years, but have come back into vogue recently with the growing popularity of Docker containers.
Docker containers launched with the aim of making it easy for developers to test and distribute applications and have taken off with a bang: Amazon, Google, Microsoft and Joyent have all announced ways to integrate and manage multiple Docker containers into their offerings.
One of the most crucial pieces of any UNIX-like operating system is the init dæmon process. In Linux, this process is started by the kernel, and it's the first userspace process to spawn and the last one to die during shutdown.
During the history of UNIX and Linux, many init systems have gained popularity and then faded away. In this article, I focus on the history of the init system as it relates to Linux, and I talk about the role of init in a modern Linux system. I also relate some of the history of the System V Init (SysV) scheme, which was the de facto standard for many Linux distributions for a long time. Then I cover a couple more modern approaches to system initialization, such as Upstart and systemd. Finally, I pay some attention to how things work in systemd, as this seems to be the popular choice at the moment for several of the largest distributions.
Among other OpenGL 4.x extensions, one of the more recent additions to OpenGL being tackled by open-source developers is ARB_shader_storage_buffer_object.
Besides Intel DRM updates landing today in DRM-Next for eventual merging into the Linux 4.2 kernel, AMD landed some changes to their HSA kernel driver named AMDKFD.
