  • IBM Announces Three New Open Source Projects for Developing Apps for Kubernetes and the Data Asset eXchange (DAX), the Linux Foundation Is Having a Sysadmin Day Sale, London Launches Open-Source Homebuilding App and Clonezilla Live 2.6.2-15 Released

    IBM this morning announces three new open-source projects that "make it faster and easier for you to develop and deploy applications for Kubernetes". Kabanero "integrates the runtimes and frameworks that you already know and use (Node.js, Java, Swift) with a Kubernetes-native DevOps toolchain". Appsody "gives you pre-configured stacks and templates for a growing set of popular open source runtimes and frameworks, providing a foundation on which to build applications for Kubernetes and Knative deployments". And Codewind "provides extensions to popular integrated development environments (IDEs) like VS Code, Eclipse, and Eclipse Che (with more planned), so you can use the workflow and IDE you already know to build applications in containers."

    IBM also today announces the Data Asset eXchange (DAX), which is "an online hub for developers and data scientists to find carefully curated free and open datasets under open data licenses". The press release notes that whenever possible, "datasets posted on DAX will use the Linux Foundation's Community Data License Agreement (CDLA) open data licensing framework to enable data sharing and collaboration. Furthermore, DAX provides unique access to various IBM and IBM Research datasets. IBM plans to publish new datasets on the Data Asset eXchange regularly. The datasets on DAX will integrate with IBM Cloud and AI services as appropriate."

  • Data as the new oil: The danger behind the mantra

    Not a week goes by that I don’t hear a tech pundit, analyst, or CIO say “data is the new oil.” This overused mantra suggests that data is a commodity that can become extremely valuable once refined. Many technologists have used that phrase with little knowledge of where it originated – I know I wasn’t aware of its origin. 

    It turns out the phrase is attributed to Clive Humby, a British mathematician who helped create British retailer Tesco’s Clubcard loyalty program. Humby quipped, “Data is the new oil. It’s valuable, but if unrefined it cannot really be used. It has to be changed into gas, plastic, chemicals, etc., to create a valuable entity that drives profitable activity; so must data be broken down, analyzed for it to have value.”

  • How to explain deep learning in plain English

    Understanding artificial intelligence sometimes isn’t a matter of technology so much as terminology. There’s plenty of it under the big AI umbrella – such as machine learning, natural language processing, computer vision, and more.

    Compounding this issue, some AI terms overlap. Being able to define key concepts clearly – and subsequently understand the relationships and differences between them – is foundational to your crafting a solid AI strategy. Plus, if the IT leaders in your organization can’t articulate terms like deep learning, how can they be expected to explain it (and other concepts) to the rest of the company?

  • How to make the case for service mesh: 5 benefits

    Service mesh is a trending technology, but that alone does not mean every organization needs it. As always, adopting a technology should be driven by the goals it helps you attain or, put another way, the problems it helps you solve.

    It’s certainly worth understanding what a service mesh does – in part so you can explain it to other people. Whether or not you actually need one really depends upon your applications and environments.

Fedora Community Blog: Application service categories and community handoff

Filed under
Red Hat

The Community Platform Engineering (CPE) team recently wrote about our face-to-face meeting where we developed a team mission statement and developed a framework for making our workload more manageable. Having more focus will allow us to progress higher priority work for multiple stakeholders and move the needle on more initiatives in a more efficient manner than how we are working right now.

During the F2F we walked through the process of how to gracefully remove ourselves from applications that are not fitting our mission statement. The next couple of months will be a transition phase as we want to ensure continuity and cause minimum disruption to the community. To assist in that strategy, we analysed our applications and came up with four classifications to which they could belong.

  • IBM Takes A Hands Off Approach With Red Hat

    IBM has been around long enough in the IT racket that it doesn’t have any trouble maintaining distinct portfolios of products that have overlapping and often incompatible functions. The System/3, which debuted in 1969, is only five years older than the System/360, which laid the foundation and set the pace for corporate computing when it launched in 1964. Both styles of machines continue to exist today as the IBM i on Power Systems platform and the System z.

    With the $34 billion acquisition of Red Hat, which closed last week, neither of those two legacy products are under threat and IBM does not seem to be inclined whatsoever in ceasing development of the legacy operating system and middleware stacks embodied in the IBM i and System z lines.

    As Arvind Krishna, senior vice president in charge of IBM’s cloud and cognitive software products, put it bluntly in a call after the deal closed, IBM’s customers expect for Big Blue to maintain its own operating systems, middleware, storage, databases, and security software in the IBM i, AIX, and System z lines, and that is precisely what Big Blue is going to do. Krisha estimated that there is only about 5 percent overlap in products between Big Blue and Red Hat – something we talked about at length when the deal was announced last October – and added that in many enterprise accounts that use both Red Hat and IBM platforms, companies invest in both sets of software for different purposes – perhaps using JBoss in one case and WebSphere in another, for instance.

  • Tech cos go for Edtech tie-ups to get that ready workforce

    Companies like Wipro, Accenture, IBM and others are tying up with edtech partners like upGrad, Simplilearn and Udacity to have a ready-trained workforce they can deploy on projects. Additional benefits include minimal training cost incurred post recruitment and a lesser churn as learners develop more ownership in their roles.

    The edtech firms provide campus recruits the required platform, content, assignments and project work in their last semester of college to ensure they are prepared with programming skills and emerging digital skills before they join.

  • Red Hat Enterprise Linux 8 improves performance for modern workloads

    Red Hat Enterprise Linux (RHEL) 8 can provide significant performance improvements over RHEL 7 across a range of modern workloads. To put this in context, we used RHEL 7.6 to execute multiple benchmarks with Intel's 2nd generation of Intel Xeon Scalable processors, and our hardware partners set 35 new world record performance results using the same OS version. This post will highlight RHEL 8 performance gains over RHEL 7.

    How did we get here? The performance engineering team at Red Hat collaborates with software partners and hardware OEMs to measure and optimize performance across workloads that range from high-end databases, NoSQL databases packaged in RHEL, Java applications, and third party databases and applications from Oracle, Microsoft SQL Server, SAS, and SAP HANA ERP applications.

    We run multiple benchmarks and measure the performance of CPU, memory, disk I/O and networking. Testing includes the filesystems we ship with Red Hat Enterprise Linux, such as XFS, Ext4, GFS2, Gluster and Ceph.

  • Federation V2 is now KubeFed

    Some time ago we talked about how Federation V2 on Red Hat OpenShift 3.11 enables users to spread their applications and services across multiple locales or clusters. As a fast moving project, lots of changes happened since our last blog post. Among those changes, Federation V2 has been renamed to KubeFed and we have released OpenShift 4.

    In today’s blog post we are going to look at KubeFed from an OpenShift 4 perspective, as well as show you a stateful demo application deployed across multiple clusters connected with KubeFed.

    There are still some unknowns around KubeFed; specifically in storage and networking. We are evaluating different solutions because we want to we deliver a top-notch product to manage your clusters across multiple regions/clouds in a clear and user-friendly way. Stay tuned for more information to come!

  • Duplicity 0.8.01

    Duplicity 0.8.01 is now in rawhide. The big change here is that it now uses Python 3. I’ve tested it in my own environment, both on it’s own and with deja-dup, and both work.

    Please test and file bugs. I expect there will be more, but with Python 2 reaching EOL soon, it’s important to move everything we can to Python 3.

Fedora vs. Ubuntu: Linux Distros Compared

Ubuntu

Fedora is a free and open source Linux-based operating system that has been around since 2003. Red Hat, the world’s largest open source company prior to being bought by IBM, sponsors the project. Fedora serves as the foundation for Red Hat Enterprise Linux, a version of Linux intended for companies and servers rather than personal desktop use.

Ubuntu became the most popular Linux-based operating system not long after launching in 2004. Billionaire Mark Shuttleworth created a company called Canonical whose purpose was to create a version of Linux for general computer users. Ubuntu was that desktop.

  • OpenShift Commons Briefing: Quay v3 Release Update and Road Map

    In this briefing, Dirk Herrmann, Red Hat’s Quay Product Manager walks through Quay v3.0’s features, and discusses the road map for future Quay releases, including a progress update on the open sourcing of Quay.

    Built for storing container images, Quay offers visibility over images themselves, and can be integrated into your CI/CD pipelines and existing workflows using its API and other automation features. Quay was first released in 2013, as the first enterprise hosted registry. Six years later, we’ve celebrated the first major release of the container registry since it joined the Red Hat portfolio of products through the acquisition of CoreOS in 2018.

Find lost files with Scalpel

Filed under
Red Hat
Software
HowTos

As a system administrator, part of your responsibility is to help users manage their data. One of the vital aspects of doing that is to ensure your organization has a good backup plan, and that your users either make their backups regularly, or else don’t have to because you’ve automated the process.

However, sometimes the worst happens. A file gets deleted by mistake, a filesystem becomes corrupt, or a partition gets lost, and for whatever reason, the backups don’t contain what you need.

As we discussed in How to prevent and recover from accidental file deletion in Linux, before trying to recover lost data, you must find out why the data is missing in the first place. It’s possible that a user has simply misplaced the file, or that there is a backup that the user isn’t aware of. But if a user has indeed removed a file with no backups, then you know you need to recover a deleted file. If a partition table has become scrambled, though, then the files aren’t really lost at all, and you might want to consider using TestDisk to recover the partition table, or the partition itself.

What happens if your file or partition recovery isn’t successful, or is only in part? Then it’s time for Scalpel. Scalpel performs file carving operations based on patterns describing unique file types. It looks for these patterns based on binary strings and regular expressions, and then extracts the file accordingly.

In my slightly infamous email to fedora-devel I stated that I would turn off the snapd support in the gnome-software package for Fedora 31. A lot of people agreed with the technical reasons, but failed to understand the bigger picture and asked me to explain myself.

I wanted to tell a little, fictional, story:

In 2012 the ISO institute started working on a cross-vendor petrol reference vehicle to reduce the amount of R&D different companies had to do to build and sell a modern, and safe, saloon car.

8 Top Ubuntu server Web GUI Management Panels

Ubuntu Server with command-line interface might sound little bit wired to newbies because of no previous familiarization. Thus, if you are new to Ubuntu Linux server running on your local hardware or some Cloud hosting and planning to install some Linux Desktop Graphical environment (GUI) over it; I would like to recommend don’t, until and unless you don’t have supported hardware. Instead, think about free and open-source Ubuntu server Web GUI Management panels. Moreover, for a moment, you can think about Desktop Graphical environment for your local server but if you have some Linux cloud hosting server, never do it. I am saying this because Ubuntu or any other Linux server operating systems are built to run on low hardware resources, thus even old computer/server hardware can easily handle it. GUI means more RAM and hard disk storage space. Read more

Ubuntu 18.10 Cosmic Cuttlefish reaches end of life on Thursday, upgrade now

Canonical, earlier this month, announced that Ubuntu 18.10 Cosmic Cuttlefish will be reaching end-of-life status this Thursday, making now the ideal time to upgrade to a later version. As with all non-Long Term Support (LTS) releases, 18.10 had nine months of support following its release last October. When distributions reach their end-of-life stage, they no longer receive security updates. While you may be relatively safe at first, the longer you keep running an unpatched system, the more likely it is that your system will become compromised putting your data at risk. If you’d like to move on from Ubuntu 18.10, you’ve got two options; you can either perform a clean install of a more up-to-date version of Ubuntu or you can do an in-place upgrade. Read more
