  • Performing A Linux System Backup The Right Way

    In order to conduct a full system backup, you need to first create a directory called bin. The second step involves informing Linux that bash will be used as the interpreter with the following command.

  • Is the Switch from Windows to Linux Really That Hard? [Ed: Bogdan Popa, Microsoft "News Editor" aka Microsoft propaganda at Softpedia, now pushing a bunch of Microsoft talking points while using entities corrupted and bribed to drop Linux as "proof" GNU/Linux is "hard"]
  • This is what HoneyComb LX2K 16-core Arm Workstation Looks Like (Video)

    Back in February 2019, while referring to Arm server, Linus Torvalds famously said: I can pretty much guarantee that as long as everybody does cross-development, the platform won’t be all that stable. Or successful.

  • Huawei open-sources MindSpore, a framework for AI app development

    Huawei this week announced that MindSpore, a framework for AI app development the company detailed in August 2019, is now available in open source on GitHub and Gitee. The lightweight suite is akin to Google’s TensorFlow and Facebook’s PyTorch, and it scales across devices, edge, and cloud environments, ostensibly lowering the barrier to entry for developers looking to imbue apps with AI.

  • Open source approach for patients arriving at the clinic with Clinic Arrivals

    Video conferencing is being done through the open source OpenVidu, which means patients simply have to click on a link in the SMS and there are no apps to download.

    The SMS gateway is provided by Twilio, which lets users send and receive text messages using web service APIs.

    Mr Grieve said OpenVidu was deliberately chosen as unlike other free offerings, it does not require patients to sign up or be given an ID, and instead allows them to get straight to the appointment.

    “This is a link that takes them straight to a website and straight into the video call on the website,” he said. “There is zero impact on the patient's end and that was really important to me. There is no app, no set-up.”

  • ISTAT (Instituto Nazionale di Statistica) distributes, under the EUPL licence, their RELAIS toolkit.

    RELAIS (REcord Linkage At IStat) is a toolkit for dealing with record linkage projects.

    The purpose of record linkage is to identify the same real world entity that can be differently represented in multiple data sources, even if unique or common identifiers are not available or are affected by errors.

  • System Hackers meeting - Lyon edition

    For the 4th time, and less than 5 months after the last meeting, the FSFE System Hackers met in person to coordinate their activities, work on complex issues, and exchange know-how. This time, we chose yet another town familiar to one of our team members as venue – Lyon in France. What follows is a report of this gathering that happened shortly before #stayhome became the order of the day. For those who do not know this less visible but important team: The System Hackers are responsible for the maintenance and development of a large number of services. From the fsfe.org website’s deployment to the mail servers and blogs, from Git to internal services like DNS and monitoring, all these services, virtual machines and physical servers are handled by this friendly group that is always looking forward to welcoming new members. Interestingly, we have gathered in the same constellation as in the hackathon before, so Albert, Florian, Francesco, Thomas, Vincent and me tackled large and small challenges in the FSFE’s systems. But we have also used the time to exchange knowledge about complex tasks and some interconnected systems. The official part was conducted in the fascinating Astech Fablab, but word has it that Ninkasi, an excellent pub in Lyon, was the actual epicentre of this year’s meeting.

  • Your occasional enterprise storage digest, featuring Commvault, Nutanix, HYCU, MariaDB and more

  • DataStax launches Kubernetes operator for open source Cassandra database

    Today, DataStax, the commercial company behind the open source Apache Cassandra project, announced an open source Kubernetes operator developed by the company to run a cloud native version of the database.

  • Didn't see that coming: DataStax emits open source Kubernetes operator for Cassandra

    NoSQL slinger DataStax has released an open source Kubernetes operator for Apache Cassandra as it seeks to cosy back up to the community. Fresh from snapping up Cassandra consultancy The Last Pickle for an undisclosed amount on 3 March, the veteran NoSQL biz has rounded out the month by opening up the source to its Kubernetes operator, replete with lessons learned from its forever-in-beta hosted Cassandra product, Astra (formerly Apollo.) Operators are one way to deal with the complexities of Kubernetes, abstracting (at least in theory) the user from the grungy bits of deploying and operating an application behind familiar Kubernetes tooling. Certainly, deploying and managing something like Cassandra in such an environment can be challenging enough without having to dive elbow-deep into the guts of thing.

  • HPE, Intel and Linux Foundation team up for open source software for 5G core

    HPE announced on Tuesday it's working with Intel and the Linux Foundation on a new open source software project to help automate the roll out of 5G across multiple sites. The new partnership, which will be under the Linux Foundation umbrella, is called the Open Distributed Infrastructure Management Framework. The partnership represents HPE's move into the 5G core network space as it branches out from its enterprise roots. Other partners for the open source project include AMI, Apstra, IBM's Red Hat, Tech Mahindra and World Wide Technology. HPE will also introduce an enterprise offering, the HPE Open Distributed Infrastructure Management Resource Aggregator.

  • What Value Does Alluxio Brings To The Presto Foundation?

    Steven Mih: The Presto Foundation is a project hosted under the Linux Foundation. It was created last year by companies like Facebook, Twitter, Alibaba and Uber. Alluxio is an open source project that is commonly used with Presto, the open source distributed SQL query engine, as well as other projects like Spark and TensorFlow. We support all these different frameworks. And since this was a foundation that was open to all, we decided to join it as one of the companies involved in that foundation.

  • Automating our Vanilla releases with GitHub actions

    Vanilla framework version 2.7.1 published at the end of February was the first fully automated release. Since then we have released two more and plan to release regular updates at least after every two-week iteration. The automated release process is not only smoother and takes less time, but also much less prone to human error. But there are still areas for possible improvements. With every major release, we are sending a newsletter describing the latest changes and additions to the Vanilla framework. This is still a very manual process that involves editing an email campaign template on MailChimp. Because the content of the email is loosely based on the release notes (that are already automated with Release Drafter), we could think of pre-populating the newsletter content with release notes. Instead of triggering the release manually using GitHub UI, we could automatically release (and publish) whenever the Vanilla version is updated in the package.json file. We already have similar workflows in place for our python packages.
