  • Kubernetes Dominates in IT Job Searches

    Kubernetes was the dominant technology skill requested by IT firms in 2018, according to a new report from jobs board Dice.

    The report, which scoured the site’s job postings, found that “Kubernetes” was far and away the skill most requested by IT recruiters and hiring managers. Nate Swanner, editor of Dice Insights, noted that Kubernetes – and to a lesser extent Terraform – led the demand of skill requests toward “containerization of apps and services, as well as the cloud.” Terraform is an infrastructure as code software by HashiCorp.

    “The popularity of these two skills suggests that companies are continuing to invest in designing their own scalable stacks that use cloud services such as [Amazon Web Services] or Azure for storage and compute,” Swanner wrote.

  • The Quest to Topple Science-Stymying Academic Paywalls

    SCIENCE IS BUILT, enhanced, and developed through the open and structured sharing of knowledge. Yet some publishers charge so much for subscriptions to their academic journals that even the libraries of the world’s wealthiest universities such as Harvard are no longer able to afford the prices. Those publishers’ profit margins rival those of the most profitable companies in the world, even though research is largely underwritten by governments, and the publishers don’t pay authors and researchers or the peer reviewers who evaluate those works. How is such an absurd structure able to sustain itself—and how might we change it?

    When the World Wide Web emerged in the ’90s, people began predicting a new, more robust era of scholarship based on access to knowledge for all. The internet, which started as a research network, now had an easy-to-use interface and a protocol to connect all of published knowledge, making each citation just a click away … in theory.

    Instead, academic publishers started to consolidate. They solidified their grip on the rights to prestigious journals, allowing them to charge for access and exclude the majority of the world from reading research publications—all while extracting billions in dollars of subscription fees from university libraries and corporations. This meant that some publishers, such as Elsevier, the science, technology, and medicine-focused branch of the RELX Group publishing conglomerate, are able today to extract huge margins—36.7 percent in 2017 in Elsevier’s case, more profitable than Apple, Google/Alphabet, or Microsoft that same year.

  • Presenting the PLOS ONE Open Quantum Computation and Simulation collection

    We are pleased to present the first papers of the PLOS ONE collection on Open Quantum Computation and Simulation to the public. Quantum information and technologies have experienced an enormous boost in the last couple of years moving from a purely academic environment to new realms in advanced research centers, startups and corporate companies. This transition requires new methodologies and approaches to fruitfully achieve the challenging goals set out by this research program.

  • The Solderdoodle Open Source Iron Rides Again

    Now, [Isaac] is back with an updated version he calls the Solderdoodle Plus. It’s still based on the heating element from the Weller BP645, but now boasts twice the power, an improved 3D printed case, an intuitive touch-based user interface, and even some LED blinkenlights for good measure. As with the original Solderdoodle the hardware and software for the device are open source and you’re invited to build your own, though kits are also available through an already fully-funded Kickstarter campaign.

    [Isaac] says that the temperature control functions on traditional corded soldering irons waste energy due to the large thermal mass they have to bring up to temperature. But with less thermal mass and a system of variable duty cycle pulsed power, he says the Solderdoodle Plus can do the same work as an old-school 60 watt iron while only consuming 10 watts. This allows the iron to maintain a constant 500°C for over an hour on the dual internal Panasonic NCR18500A lithium-ion batteries, and means you can charge it up with nothing more exotic than a micro USB cable.

  • How Trulia began paying down its technical debt

    As every software company knows, over time as code ages and workarounds build on work-arounds, the code base becomes bloated. It becomes ever more difficult to get around the technical debt that you’ve built up over time. It’s really impossible to avoid this phenomenon, but at some point, companies realize that the debt is so great that it’s limiting their ability to build new functionality. That’s precisely what Trulia faced in 2017 when it began a process of paying down that debt and modernizing its architecture.

    Trulia is a real estate site founded way back in 2005, an eternity ago in terms of technology. The company went public in 2012 and was acquired by Zillow in 2014 for $3.5 billion, but has continued to operate as an independent brand under the Zillow umbrella. It understood that a lot had changed technologically in the 12 years since its inception when engineering began thinking about this. The team knew it had a humongous, monolithic code base that was inhibiting the ability to update the site.

  • Essential System Tools: fdupes – find or delete duplicate files

    This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at fdupes. For details of all tools in this series, please check the summary page.

    Even though the cost of storage per GB continues to fall, it’s common for users to need to find and remove duplicates files. The process of finding and removing duplicates is time-consuming. Fortunately, there are a number of tools that are designed to remove the laborious nature of finding duplicates. fdupes is a tool that we gravitate towards.

    The software finds duplicate files in a given set of directories and sub-directories. It recognizes duplicates by comparing MD5 signature of files followed by a byte-to-byte comparison. The utility offers a lot of options to list, delete and replace files.

    GNOME Release Videos Needs New Hands!

    It’s hard for me to let go, but reason tells me that it is time to pass on the torch with release video production for the time being. 10 videos is a great round number and a good place for me to step down. None of them were ever a stand-alone project and I deeply thank everyone for their contributions, small and big! I’m far from convinced that I have hit the right magic release video flavor yet, but they require a large concentration of time that I no longer have on my hands to give. That said, get in touch if you are interested in being the next video production person! I will gladly supervise, pass on necessary details and give feedback in the process of it all. I’m unfortunately hard to get hold off on IRC/matrix these days, but quiet easy to get hold of on telegram and e-mail.

  • 3 serverless platform approaches to consider

    Once you decide to move to a serverless architecture, it's important to realize this is just a place to start. Now, there are several paths you can take and lots of questions to ask yourself before you choose a specific architectural approach.  

    For example, will you choose a commercial or an open-source-based option? You can opt for loosely coupled tools or a well-integrated development platform. Will you use the serverless platform for hobby projects, or is it for serious enterprise applications?

    Serverless technologies change quickly. So, before you choose a platform, evaluate all of your options. Let's review what's available today.

  • Erase unconscious bias from your AI datasets

    Artificial intelligence failures often generate a lot of laughs when they make silly mistakes like this goofy photo. However, "the problem is that machine learning gaffes aren't always funny … They can have pretty serious consequences for end users when the datasets that are used to train these machine learning algorithms aren't diverse enough," says Lauren Maffeo, a senior content analyst at GetApp.

    In her Lightning Talk, "Erase unconscious bias from your AI datasets," at All Things Open 2018, October 23 in Raleigh, NC, Lauren describes some of the grim implications and advocated for developers to take measures to protect people from machine learning and artificial intelligence bias.

  • A message from Richard M. Stallman

    This year, I'm happy to report, the Free Software Foundation (FSF) received two large donations, each nominally a million dollars.

    The donation from the Pineapple Fund arrived in the form of Bitcoin and had gone down to around $860,000 by the time we could convert it all to dollars. Around half of the donation from Handshake is earmarked for specific software projects; some of that will go to improving Replicant, the free Android fork, but that half won't help fund the FSF's general operations.

    We will need to add part of these donations to our reserves, which are meant to enable us to keep operating in the case of a possible downturn. That still leaves enough to expand our staff by two or three positions. We will be able to do some of the work that always needed doing but that we could not undertake.

  • Lawrence Roberts, One Of Early Internet Pioneers, Dies At 81

  • Open Source Domain Controller

    Is there an open source domain controller (DC) worth considering? There are a number of open source DCs available and many of them could end up representing interesting solutions for your organization. Often, solutions pertaining to the directory services realm end up functioning as domain controllers for organizations. Many of the solutions considered are either OpenLDAP™, FreeIPA, Samba, and a slew of others.

  • Using JupyterHub as a generic application spawner

    As part of my day job I occasionally need to give workshops on using OpenShift, Red Hat's distribution of Kubernetes. The workshop notes that attendees follow to do the exercises we host using an internally developed tool called workshopper. We host the workshop notes using this tool inside of the same OpenShift cluster that users will be working in.

    To access the OpenShift cluster and do the exercises, attendees use the OpenShift command line clients oc or odo. They may also need to use kubectl. Because these are client side tools they would need to be installed somewhere where the attendees can run them, usually this is on their own local computer.

    Requiring that attendees install a client on their own local computer can often be a challenge. This is because when dealing with enterprise customers, their employee's computers may be locked down such that they are unable to install any additional software.

    A solution one often sees to this problem is to enhance the tool used to host the workshop notes to embed an interactive terminal which is then used through the web browser. Behind the scenes that terminal would be connected up to some backend system where a shell environment is run for the specific user accessing the workshop. Finally, in that shell environment they would have access to all the command line tools, as well as other files, that may be needed for that workshop.

  • Host your website safely and avoid website cross-contamination issues

    This article discusses the hidden pitfalls of hosting multiple websites on one hosting account, and how you can remediate the consequences of website cross-contamination.

    The structure of virtual hosting (also known as shared hosting) can be illustrated by a bee hive: each website (bee) has its own folder (cell). At the same time, all bees share the same hive (hosting account resources, such as disk space, database, RAM, CPU, etc.).

    In most cases, hosting companies do not provide resource isolation for shared hosting accounts (plans that let you host multiple websites on one account). In practice, that means that all website files are owned by the same system user, and server scripts (using PHP, Python, Perl, etc.) on each website on the account run with equal access rights. So, we get into a situation where the scripts of one website on the account may create, remove or modify any file on any other website hosted on the same shared hosting account.


    I hope this information helps you to avoid mass infection or hacking issues with your websites, or, if this has already happened, effectively resolve the incident. Along with professional security advice, a comprehensive security solution such as Imunify360 is essential to keep such incidents from happening in the first place.

  • Best of 2018: 5 Open Source SIEM Tools Worth Checking Out

    Security information and event management (SIEM) is the cornerstone of IT security. All other network solutions are merely data flows that feed into an organization’s SIEM. Not all SIEMs are created equal, and their capabilities can vary wildly. Choosing the right one for your needs can mean the difference between detecting a security weakness and becoming just another statistic.
    A SIEM solution is a combination of a security event management (SEM) system and a security information management (SIM) system. SEMs monitor servers and networks in real time, while SIMs store the data.

  • Europe Speeds Ahead on Open Access: 2018 in Review

    Open access is the common-sense idea that scientific research (especially scientific research funded by the government or philanthropic foundations) should be available to the public—ideally with no legal or technical barriers to access and reuse. EFF is a longtime supporter of the open access movement: we think that promoting broad access to knowledge and information helps to ensure that everyone can speak out and participate in society.

    For over five years now, EFF and our allies in the open access world have been campaigning for the Fair Access to Science and Technology Research Act (FASTR, S. 1701, H.R. 3427). Despite broad support from both parties and barely any opposition from anyone besides major publishers, Congress continues to snooze on FASTR year after year.

    While Congress dragged its feet on important legislative fixes, the most exciting changes came in Europe and at the state level.

    This year, though, something changed. Europe soared ahead of the United States with the Plan S initiative, a plan to require government-funded research to be made available to the public on the date of publication by the year 2020. Thirteen government agencies that fund research have endorsed Plan S, as well as a few foundations.

Out-Of-The-Box 10GbE Network Benchmarks On Nine Linux Distributions Plus FreeBSD 12

Last week I started running some fresh 10GbE Linux networking performance benchmarks across a few different Linux distributions. That testing has now been extended to cover nine Linux distributions plus FreeBSD 12.0 to compare the out-of-the-box networking performance. Tested this round alongside FreeBSD 12.0 was Antergos 19.1, CentOS 7, Clear Linux, Debian 9.6, Fedora Server 29, openSUSE Leap 15.0, openSUSE Tumbleweed, Ubuntu 18.04.1 LTS, and Ubuntu 18.10. All of the tests were done with a Tyan S7106 1U server featuring two Intel Xeon Gold 6138 CPUs, 96GB of DDR4 system memory, and Samsung 970 EVO SSD. For the 10GbE connectivity on this server was an add-in HP NC523SFP PCIe adapter providing two 10Gb SPF+ ports using a QLogic 8214 controller. Read more
