Learning About Enea's Real Time Linux Embedded OS (Video) 27

Posted by Roblimo
from the not-quite-real-time-but-almost dept.
Jon Aldama is the Product Marketing Manager for Enea A.B., but he prides himself on being a developer first and a marketer second -- a point he stresses early in today's video. Enea is behind Operating System Embedded, whose Wikipedia page, some say, "appears to be written like an advertisement," which an unkind person could also say about the Enea A.B. Wikipedia page. In any case, Enea works with the Linux Foundation's Yocto Project workgroup, whose main webpage says, "It's not an embedded Linux distribution – it creates a custom one for you." This is all open source, which Jon says is a big corporate principle at Enea -- and he should know, since his previous job was as an Open Source Compliance Officer and Software Analyst at Ericsson.

Is It Time To Split Linux Distros In Two? 282

Posted by samzenpus
from the programming-of-solomon dept.
snydeq writes Desktop workloads and server workloads have different needs, and it's high time Linux consider a split to more adequately address them, writes Deep End's Paul Venezia. You can take a Linux installation of nearly any distribution and turn it into a server, then back into a workstation by installing and uninstalling various packages. The OS core remains the same, and the stability and performance will be roughly the same, assuming you tune they system along the way. Those two workloads are very different, however, and as computing power continues to increase, the workloads are diverging even more. Maybe it's time Linux is split in two. I suggested this possibility last week when discussing systemd (or that FreeBSD could see higher server adoption), but it's more than systemd coming into play here. It's from the bootloader all the way up. The more we see Linux distributions trying to offer chimera-like operating systems that can be a server or a desktop at a whim, the more we tend to see the dilution of both. You can run stock Debian Jessie on your laptop or on a 64-way server. Does it not make sense to concentrate all efforts on one or the other?"

GSOC Project Works To Emulate Systemd For OpenBSD 314

Posted by timothy
from the everyone's-idea-of-a-good-time dept.
An anonymous reader writes Through a Google Summer of Code project this year was work to emulate systemd on OpenBSD. Upstream systemd remains uninterested in supporting non-Linux platforms so a student developer has taken to implementing the APIs of important systemd components so that they translate into native systemd calls. The work achieved this summer was developing replacements for the systemd-hostnamed, systemd-localed, systemd-timedated, and systemd-logind utilities. The hope is to allow for systemd-dependent components like more recent versions of GNOME to now run on OpenBSD.

Fedora To Get a New Partition Manager 170

Posted by timothy
from the nostalgia-is-a-hard-force-to-overcome dept.
sfcrazy writes Developer Vratislav Podzimek has announced the next-gen partition manager for Fedora, blivet-gui. It is eventually going to replace GParted, the most popular GUI based partition manager, found in all major distros. The new tool is named blivet-gui after the blivet python library (originally Anaconda's storage management and configuration tool). The need of a new partition manager stems from the fact that none of the existing GUI partitioning tools supports all modern storage technologies. Fedora's Anaconda base supports all, though, and is hence chosen as the back-end for this new tool. The application is only a few months old but is already looking nice and useful. Features like RAID and BTRFS support are being worked on. Vojtech Trefny is the other developer working with Vratislav on blivet-gui. Here's the announcement.

Why Munich Will Stick With Linux 185

Posted by Soulskill
from the don't-change-penguins-in-the-middle-of-a-stream dept.
Jason Hibbets writes: "There are many solved problems in open source. Groupware is not one of them," Georg Greve, co-founder and CEO of Kolab System starts off his post highlighting recent features of the latest release of the Kolab groupware project. He calls out a few newly elected politicians that don't like the current set-up, but says that thousands of users don't have the same experience. "Until today, the city of Munich is using the same stand-alone calendaring and email systems it had used when it was still fully operating on Windows. Updating these systems had a lower priority than the migration to LiMux then. But an upgrade is underway now. And, the solution they chose is agnostic to the desktop platform and will service LiMux and Windows alike. The primary difference made by another migration would likely be due to the perils that come with any migration, such as additional costs and delays. In other words: The very problem used to criticize the LiMux desktop is already being solved."

Akamai Warns: Linux Systems Infiltrated and Controlled In a DDoS Botnet 230

Posted by timothy
from the strutting-around-like-they-own-the-place dept.
An anonymous reader writes Akamai Technologies is alerting enterprises to a high-risk threat of IptabLes and IptabLex infections on Linux systems. Malicious actors may use infected Linux systems to launch DDoS attacks against the entertainment industry and other verticals. The mass infestation of IptabLes and IptabLex seems to have been driven by a large number of Linux-based web servers being compromised, mainly by exploits of Apache Struts, Tomcat and Elasticsearch vulnerabilities. Attackers have used the Linux vulnerabilities on unmaintained servers to gain access, escalate privileges to allow remote control of the machine, and then drop malicious code into the system and run it. As a result, a system could then be controlled remotely as part of a DDoS botnet. The full advisory is available for download only with registration, but the (Akamai-owned) Prolexic page to do so is quite detailed.

Bringing New Security Features To Docker 29

Posted by timothy
from the password-is-stevedore dept.
Czech37 writes SELinux lead Dan Walsh wrote last month that Docker "containers do not contain" and that the host system isn't completely protected. Today, Walsh details the steps that Docker, Red Hat, and the open source community are taking to make Docker more secure: "Basically, we want to put in as many security barriers to break out as possible. If a privileged process can break out of one containment tool, we want to block them with the next. With Docker, we are want to take advantage of as many security components of Linux as possible. If "Docker" isn't a familiar word, the project's website is informative; the very short version is that it's a Linux-based "open platform for developers and sysadmins to build, ship, and run distributed applications"; Wikipedia has a good explanation, too.

You Got Your Windows In My Linux 613

from the entirely-uncontroversial-opinions dept.
snydeq writes: Ultimately, the schism over systemd could lead to a separation of desktop and server distros, or Linux server admins moving to FreeBSD, writes Deep End's Paul Venezia. "Although there are those who think the systemd debate has been decided in favor of systemd, the exceedingly loud protests on message boards, forums, and the posts I wrote over the past two weeks would indicate otherwise. I've seen many declarations of victory for systemd, now that Red Hat has forced it into the enterprise with the release of RHEL 7. I don't think it's that easy. ... Go ahead, kids, spackle over all of that unsightly runlevel stuff. Paint over init and cron, pam and login. Put all of that into PID1 along with dbus. Make it all pretty and whisper sweet nothings about how it's all taken care of and you won't have to read a manual or learn any silly command-line stuff. Tune your distribution for desktop workloads. Go reinvent Windows."

sfcrazy (1542989) writes, based on a report from Ted T'so, that Kernel developer Dmitry Monakhov was detained for 15 days for disobeying a police officer. The debacle came about when Monakhov decided to protest the recent invasion into Ukraine by Russian armed forces. Monakhov is using Twitter to keep people informed about his experience with the Russian judicial system; a human translator can probably do a better job than Google in this case.

Ask Slashdot: Linux-Friendly Desktop x86 Motherboard Manufacturers? 294

Posted by Soulskill
from the roll-your-own dept.
storkus writes: The release of Haswell-E and a price drop on Devil's Canyon has made me itch for a PC upgrade. However, looking around I discovered a pair of horror stories on Phoronix about the difficulties of using Linux on a multitude of motherboards. My question: if MSI, Gigabyte, Asus (and by extension Asrock) are out, who's left and are they any good? I'd like to build a (probably dual-boot, but don't know for sure) gaming and 'other' high-end machine with one of the above chips, so we're talking Z97 or X99; however, these stories seem to point to the problems being Windows-isms in the BIOS/UEFI structures rather than actual hardware incompatibility, combined with a lousy attitude (despite the Steam Linux distro being under development).

MIPS Tempts Hackers With Raspbery Pi-like Dev Board 88

Posted by timothy
from the do-what-thou-will dept.
DeviceGuru (1136715) writes "In a bid to harness the energy and enthusiasm swirling around today's open, hackable single board computers, Imagination Technologies, licensor of the MIPS ISA, has unveiled the Creator C120 development board, the ISA's counter to ARM's popular Raspberry Pi and BeagleBone Black SBCs. The MIPS dev board is based on a 1.2GHz dual-core MIPS32 system-on-chip and has 1GB RAM and 8GB flash, and there's also an SD card slot for expansion. Ports include video, audio, Ethernet, both WiFi and Bluetooth 4.0, and a bunch more. OS images are already available for Debian 7, Gentoo, Yocto, and Arch Linux, and Android v4.4 is expected to be available soon. Perhaps the most interesting feature of the board is that there's no pricing listed yet, because the company is starting out by giving the boards away free to developers who submit the most interesting projects."

darthcamaro (735685) writes Since November of 2001, Brian Stevens has been the CTO of Red Hat. As of August 28, that's no longer the case. Under Stevens' tenure, Red Hat transformed its business, adding Red Hat Enterprise Linux, acquiring JBoss, Qumranet, Gluster and Ceph as well as joining (and now leading) the OpenStack Foundation. So why did he leave? No official word, but apparently it is to pursue a new opportunity that Stevens just could not pass up.

How Red Hat Can Recapture Developer Interest 232

Posted by Soulskill
from the cookies-will-do-the-trick dept.
snydeq writes: Developers are embracing a range of open source technologies, writes Matt Asay, virtually none of which are supported or sold by Red Hat, the purported open source leader. "Ask a CIO her choice to run mission-critical workloads, and her answer is a near immediate 'Red Hat.' Ask her developers what they prefer, however, and it's Ubuntu. Outside the operating system, according to AngelList data compiled by Leo Polovets, these developers go with MySQL, MongoDB, or PostgreSQL for their database; Chef or Puppet for configuration; and ElasticSearch or Solr for search. None of this technology is developed by Red Hat. Yet all of this technology is what the next generation of developers is using to build modern applications. Given that developers are the new kingmakers, Red Hat needs to get out in front of the developer freight train if it wants to remain relevant for the next 20 years, much less the next two."

IBM Gearing Up Mega Power 8 Servers For October Launch 113

darthcamaro (735685) writes "Now that IBM has sold off its x86 server business to Lenovo, it's full steam ahead for IBM's Power business. While Intel is ramping up its next generation of server silicon for a September launch, IBM has its next lineup of Power 8 servers set to be announced in October. "There is a larger than 4U, 2 socket system coming out," Doug Balog, General Manager of Power Systems within IBM's System and Technology Group said. Can IBM Power 8 actually take on x86? Or has that ship already sailed?" At last weekend's Linux Con in Chicago, IBM talked up the availability of the Power systems, and that they are working with several Linux vendors, including recently-added Ubuntu; watch for a video interview with Balog on how he's helping spend the billion dollars that IBM pledged last year on open source development.

Choose Your Side On the Linux Divide 826

Posted by samzenpus
from the picking-a-team dept.
snydeq writes The battle over systemd exposes a fundamental gap between the old Unix guard and a new guard of Linux developers and admins, writes Deep End's Paul Venezia. "Last week I posted about the schism brewing over systemd and the curiously fast adoption of this massive change to many Linux distributions. If there's one thing that systemd does extremely well, it is to spark heated discussions that devolve into wild, teeth-gnashing rants from both sides. Clearly, systemd is a polarizing subject. If nothing else, that very fact should give one pause. Fundamental changes in the structure of most Linux distributions should not be met with such fervent opposition. It indicates that no matter how reasonable a change may seem, if enough established and learned folks disagree with the change, then perhaps it bears further inspection before going to production. Clearly, that hasn't happened with systemd."

There was a review of the city's IT systems that was called for by the mayor, but it wasn't solely just to decide on whether to move back to Microsoft. And while there have been complaints about LiMux, they mostly seem to concern compatibility with OpenOffice.org, which may well be resolved by switching to LibreOffice."

Virtual Machine Brings X86 Linux Apps To ARMv7 Devices 61

Posted by timothy
from the ever-widening-abstraction-layers dept.
DeviceGuru writes Eltechs announced a virtual machine that runs 32-bit x86 Linux applications on ARMv7 hardware. The ExaGear VM implements a virtual x86 Linux container on ARMv7 computers and is claimed to be 4.5 times faster than QEMU, according to Eltechs. The VM is based on binary translation technology and requires ARMv7, which means it should run on mini-PCs and SBCs based on Cortex-A8, A7, A9, and A15 processors — but sadly, it won't run on the ARM11 (ARMv6) SoC found on the Raspberry Pi. It also does not support applications that require kernel modules. It currently requires Ubuntu (v12.04 or higher), but will soon support another, unnamed Linux distro, according to Eltechs, which is now accepting half price pre-orders without payment obligation.

Torvalds doesn't see the desktop as being a kernel problem at this point, either, but rather one about infrastructure. While not ready to declare a "Year of the Linux Desktop" he still expects that to happen — one day.

Operating Systems Still Matter In a Containerized World 129

Posted by Soulskill
from the try-to-contain-yourself dept.
New submitter Jason Baker writes: With the rise of Docker containers as an alternative for deploying complex server-based applications, one might wonder, does the operating system even matter anymore? Certainly the question gets asked periodically. Gordon Haff makes the argument on Opensource.com that the operating system is still very much alive and kicking, and that a hardened, tuned, reliable operating system is just as important to the success of applications as it was in the pre-container data center.
