  • Device Tree Microconference Accepted into 2016 Linux Plumbers Conference

    Device-tree discussions are probably not quite as spirited as in the past, however, device tree is an active area. In particular, significant issues remain.

  • OpenSchool 2016 in Brno

    Last week Red Hat Czech has for the first time hoster a very special event. We've called it OpenSchool and the purpose of the event was to explain to high school students trends in IT, trends in software development as well as why should they care about opensource. It was fairly tough for us to figure out the level of knowledge that these kids between 12-16 years of age know about IT now. Sure they use smart phones daily, are on most of social networks and intuitively use tons of different applications - but do they know how their favorite apps are developed and what powers their daily used social network in the back?

  • Event report: rootconf 2016

    Rootconf is the largest DevOps, and Cloud infrastructure related conference in India. This year’s event happened on 14-15th April in the MLR convention center, Bangalore. I traveled on the day one of the event from Pune. Woke up by 3AM in the morning, and then took the first flight to Bangalore. Picked up Ramky on my way to the venue. Managed to skip most of the (in)famous Bangalore traffic thanks to a govt holiday.

  • The night I became a hacker

    You may ask yourself, how does one become a hacker?

Debian

Technologic’s open-spec “TS-7680” SBC runs Debian on an ARM9 i.MX286, and offers up to 4GB eMMC, WiFi, BT, wide-range power, and -40 to 85°C.

Technologic’s TS-7680 single board computer uses the same NXP/Freescale i.MX286 system-on-chip found on last year’s TS-7670 and the TS-7400-V2 SBC that came out in 2014.

The power-sipping i.MX286 has an ARM926EJ-S core clocked from 261MHz to 454MHz, which can be adjusted on the fly on the TS-7680. There’s also a modest onboard FPGA. Like the TS7670 and TS-7400-V2, the TS-7680 is an open spec board with voluminous posted schematics and pre-installed Debian Linux.

  • Unix's file durability problem

    The core Unix API is overall a reasonably well put together programming environment, one where you can do what you need and your questions have straightforward answers. It's not complete by any means and some of the practical edges are rough as a result of that, but the basics are solid. Well. Most of the basics.

  • PCI Microconference Accepted into 2016 Linux Plumbers Conference

    Given that PCI was introduced more than two decades ago and that PCI Express was introduced more than ten years ago, one might think that the Linux plumbing already did everything possible to support PCI.

    One would be quite wrong.

    One issue with current PCI support is that resource allocation is handled on a per-architecture basis, leading to duplicate code, and, worse yet, duplicate bugs. This microconference will therefore look into possible consolidation of this code.

ROSA R7 Desktop Fresh review - Thorny fun

Filed under
Linux
Reviews

ROSA R7 Desktop Fresh is an interesting project. It has a unique spin, its own flair and identity, and it blends the old, proven - and not so proven - concepts from Mandriva with modern technology and looks. The end result is quite polar, or rather bi-polar. You will either love it or hate it. Functionality wise, most if not everything I tried worked.

While the virtual machine testing doesn't really provide the necessary confidence needed to ascertain the value of a distro, I think R7 is worth testing, provided it agrees with your hardware. I'm an unlucky one in that regard. There are lots of things that can be improved, including some real, actual functionality bugs, a more modern and streamlined installer, more intuitive package manager and system menu, and such. But then, you get classic good looks, KDE style, multimedia playback, a rich repertoire of programs out of the box, and a robust design. Perhaps one day I will be able to experience all these outside the Matrix. 6.5/10. See you around.

Finding the signal in the noise of Linux system monitoring

Filed under

Linux
Server

I'd have to say Datadog is my favorite tool at the moment! And it's not because they're my employer. It's actually the other way around. The reason I joined Datadog this past summer was due to how much I loved using their products as a customer. We're a mix of a hosted service and open source agent that runs on your servers to collect metrics. We tend to focus on environments with dynamic infrastructure (containers, cloud, and auto-scaling or scheduled workloads), as well as aggregating metrics from a number of sources including other monitoring systems.

The open source world has seen some great developments and improvements in our toolsets in recent years. While Nagios and Cacti or Ganglia have been the workhorses of the open source monitoring stack for the better part of the last 20 years, we now have a number of new tools such as Graphite and Graphana for time series data, ELK for log management, and much more.

  • Linux 4.6-rc4

    It's been a fairly calm week, and rc4 is not all that big. Nor is
    there anything particularly scary in there.

    Changes all over the tree, with drivers (40%) and architecture fixes
    (30%) being the bulk of it. The rest is scattered all over, but it's
    all pretty small. In fact, the "VM fixes" show up as 5+% of the patch,
    but that's literally just because we got rid of the conversion-time
    hack to have a couple of different calling conventions for
    get_user_pages().

  • Linux 4.6-rc4 Kernel Released

    Linus Torvalds just tagged the Linux 4.6-rc4 kernel release. It's been another week of many bug/regression fixes throughout the kernel's many subsystems. It will still be a few weeks before Linux 4.6 is officially christened.

  • Linus Torvalds Announces Linux Kernel 4.6 RC4, Things Are Calm for Now

    Another Sunday, another chance for us, Linux enthusiasts, to take the latest RC (Release Candidate) build of the upcoming 4.6 kernel for a test drive on our computers.

  • Mixing Linux and ZFS, LinuxFest NorthWest and More…

    It’s LinuxFest NorthWest time! I’ve never been to LFNW, but I have a soft spot in my heart for it’s hometown of Bellingham, Washington. Back in the day — we’re talking the late 1960s and early 70s — Bellingham was home to a hippie underground newspaper, Northwest Passage, that was known in counterculture circles of the day across the continent. Alas, the Passage has been gone since ’86, but its spirit seems to live on in a high techy, Linuxy sort of way at LFNW. From what I’ve seen, LFNW seems to be the most community driven and for-the–people of the major festivals in the U.S.

  • Reflections on Starting a Local FOSS Group

    Last Wednesday was no less than the third time the local FOSS group in Aalborg met. Today I’m looking back at how it all started so I thought I would share some thoughts that may help others who would like to spread free and open source software in their local area.

  • Here's An Ubuntu Kernel Build If You Want To Help Test Nouveau Boost Support

    If you have a NVIDIA GeForce 600/700 "Kepler" graphics card and wish to help out the Nouveau driver developers by testing out the experimental "boost" re-clocking patches covered yesterday on Phoronix thanks to the work by Karol Herbst, here's a 4.5-based Ubuntu kernel build to try out this weekend.

  • Nouveau "Boost" Patches Show Much Performance Potential

    Karol Herbst has been one of the independent developers leading the charge to improve Nouveau re-clocking support. Within his Git tree he's been queuing up re-clocking and voltage handling improvements for this reverse-engineered NVIDIA Linux driver. He's hoping the improved re-clocking code will be ready for the Linux 4.7~4.8 kernel, but I decided to try out his Git tree this week for some benchmarking of this experimental support.

Leftovers: OSS

Security Leftovers

  • Security updates for Thursday
  • OpenSSL patches two high-severity flaws
    OpenSSL has released versions 1.0.2h and 1.0.1t of its open source cryptographic library, fixing multiple security vulnerabilities that can lead to traffic being decrypted, denial-of-service attacks, and arbitrary code execution. One of the high-severity vulnerabilities is actually a hybrid of two low-risk bugs and can cause OpenSSL to crash.
  • Linux Foundation Advances Security Efforts via Badging Program
    The Linux Foundation Core Infrastructure Initiative's badging program matures, as the first projects to achieve security badges are announced.
  • Linux Foundation tackles open source security with new badge program
  • WordPress Plugin ‘Ninja Forms’ Security Vulnerability
    FOSS Force has just learned from Wordfence, a security company that focuses on the open source WordPress content management platform, that a popular plugin used by over 500,000 sites, Ninja Forms, contains serious security vulnerabilities.
  • Preparing Your Network for the IoT Revolution
    While there is no denying that IP-based connectivity continues to become more and more pervasive, this is not a fundamentally new thing. What is new is the target audience is changing and connectivity is becoming much more personal. It’s no longer limited to high end technology consumers (watches and drones) but rather, it is showing up in nearly everything from children’s toys to kitchen appliances (yes again) and media devices. The purchasers of these new technology-enabled products are far from security experts, or even security aware. Their primary purchasing requirements are ease of use.
  • regarding embargoes
    Yesterday I jumped the gun committing some patches to LibreSSL. We receive advance copies of the advisory and patches so that when the new OpenSSL ships, we’re ready to ship as well. Between the time we receive advance notice and the public release, we’re supposed to keep this information confidential. This is the embargo. During the embargo time we get patches lined up and a source tree for each cvs branch in a precommit state. Then we wait with our fingers on the trigger. What happened yesterday was I woke up to a couple OpenBSD developers talking about the EBCDIC CVE. Oh, it’s public already? Check the OpenSSL git repo and sure enough, there are a bunch of commits for embargoed issues. Pull the trigger! Pull the trigger! Launch the missiles! Alas, we didn’t look closely enough at the exact issues fixed and had missed the fact that only low severity issues had been made public. The high severity issues were still secret. We were too hasty.
