Black Lab Enterprise Linux 8 Service Pack 1 Supports Rebootless Kernel Installs

Filed under

Softpedia was informed by the Black Lab Linux development team about the immediate availability of the first Service Pack (SP) of the Black Lab Enterprise Linux 8 OS.

Based on the long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system, Black Lab Enterprise Linux 8 Service Pack 1 (SP1) is now powered by Linux kernel 4.4.0-45.66, the same version used upstream, which is patched against the nasty "Dirty COW" bug that could have allowed a local attacker to gain administrative privileges.

Now that Canonical is offering kernel live patch services for its Ubuntu 16.04 LTS release, Black Lab Linux developers also implemented the well-known Kspice tool for offering users rebootless kernel installs. Additionally, Black Lab Enterprise Linux 8 SP1 adds full UEFI support and the ability to install Snap packages.

"Service Pack 1 is jam packed full of innovations and features," reads the announcement. "Black Lab Enterprise Linux is the fastest growing Enterprise desktop Linux offering on the market today. Black Lab Enterprise Linux 8.0 SP1 is a hybrid operating system meaning you can deploy local applications that you need as well as the cloud-based applications that you want."

Upgrading to Yakkety

Filed under

I UPGRADED the operating system on my MacBook Air last week and I figured I ought to do the same on my Linux desktop.

Moving from Ubuntu 16.04 (Xenial Xerus) to 16.10 (Yakkety Yak) on my desktop PC was nowhere as quick and easy as it was to upgrade from OS X 10.11 to macOS 10.12, but the process was nonetheless pretty straightforward and relatively trouble-free.

While it took less than an hour to perform the upgrade on my Mac, it took several hours to download and install the latest version of Ubuntu.

Much has already been written about how Unity 8, the new converged interface being developed for mobile and desktop devices, again failed to make it to the latest version of Ubuntu—although a rough preview of it is built into Yakkety (just log out and choose Unity 8 in the log-in screen).

On the surface, Ubuntu 16.10 doesn’t look very different than previous releases, and its built-in Unity 7.5 interface features just minor improvements and a few bug fixes.

To find out what’s new about Ubuntu 16.10, you have to look inside.

LinuxAndUbuntu Review Of Gentoo Linux - A Linux Distro For Advanced Users

Filed under

Many people think that Gentoo is just another Linux distro, but it is wrong. Gentoo Linux is a special, different and powerful Linux distribution, because it isn’t like other systems that have pre-compiled software and tools for easy management, in Gentoo the user must configure everything.

  • 4 Useful Cinnamon Desktop Applets

    The Cinnamon desktop environment is incredibly popular, and for good reason. Out of the box it offers a clean, fast and well configured desktop experience.

    But that doesn’t mean that you can’t make it a little better with a few nifty extras.

    And that’s where Cinnamon Applets come in. Like Unity’s Indicator Applets and GNOME Extensions, Cinnamon Applets let you add additional functionality to your desktop quickly and easily.

  • GNOME Core Apps Hackfest

    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop.

    Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.

Onchain provides the bottom-layer framework for Ali Cloud, including its open-source blockchain capabilities, to enable any company to customize its own enterprise-level blockchain.

  • Netflix on Firefox for Linux

    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround.

    For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

  • How open access content helps fuel growth in Indian-language Wikipedias

    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.

  • Where to find the world's best programmers

    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

  • AtScale Delivers Findings on BI-Plus-Hadoop

    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries.

    As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.

  • Study Says OpenStack at Scale Can Produce Surprising Savings

    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services.

    The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.

It's been great seeing all of the independent graphics renderers/engines being tried by different individuals, tons of different Vulkan samples, and a lot of other innovative projects around Vulkan, many of which I've written about in the past few months on Phoronix. One of the projects I see being regularly updated when checking on weekends and haven't written about yet is LLGL, the Low-Level Graphics Library.

  • Spark on Kubernetes at Spark Summit EU

    I’ll be speaking about Spark on Kubernetes at Spark Summit EU this week. The main thesis of my talk is that the old way of running Spark in a dedicated cluster that is shared between applications makes sense when analytics is a separate workload. However, analytics is no longer a separate workload — instead, analytics is now an essential part of long-running data-driven applications. This realization motivated my team to switch from a shared Spark cluster to multiple logical clusters that are co-scheduled with the applications that depend on them.

    As the Internet of Things gets more popular new questions arise: which protocol will become the open standard for supporting IoT networks across a huge array of devices around the world? Today we start hearing some answers from Russia.

    Igor Shchyogolev, former Minister of Telecommunications between 2008 and 2012, is thinking about a service that involves both an Internet card and a City card for citizen to use the Internet, hence named “Internet + City card” or just “Internet + City”. Long story short, Russia is contemplating the hypothesis of domestic regulation, rather than an intergovernmental agreement between major countries involved. Testament to this intent are Russian focus towards cryptographic protection and the plan of the country to substain such autarchics drives with national production of chips and direct control of both analog and digital TV frequencies.

Remote Linux Support Software: Top Picks for Linux Support

Filed under

Having remote support for Linux work with one release, then completely stopping Linux support with the next application release is a frustrating experience. Sometime ago, we watched this happen with Splashtop. What's even lazier on their part, is that they can't be bothered to remove the obsolete Linux packages.

Then you had options like Mikogo. They went from supporting remote support for Linux users to acknowledging in a blog post that this is no longer the case. To be fair, the software is still available if you know where to look for it. However it's not a good idea to rely on unsupported software.
