  • Breaking IT Down: What Is Kubernetes?

    Kubernetes is an open source tool used for automating and managing container operations. Ever since its launch as an open source platform in 2014, Kubernetes has grown to become the preferred choice for container orchestration. It has the support of tech majors and is the most popular open source project after Linux among the open source community of developers.

    Container technology enables packaging of an application together with all its dependencies, such as OS, SSL libraries, and configuration files, into a single container. This technology is not new; it has been a part of Linux operations for years.

  • Platform9 Extends Scope of Kubernetes Services

    Platform9 announced this week it is adding support for a range of complementary technologies to the managed Kubernetes service it already provides.

    Company CEO Sirish Raghuram says now that Kubernetes adoption is achieving critical mass, organizations are looking to invoke additional services. Platform9 now supports the open source Prometheus monitoring tools and an instance of the open source MySQL database to support stateful containerized applications running on Kubernetes that need access to persistent sources of data.

  • We’re talking Kubernetes at TC Sessions: Enterprise with Google’s Aparna Sinha and VMware’s Craig McLuckie

    Over the past five years, Kubernetes has grown from a project inside of Google to an open source powerhouse with an ecosystem of products and services, attracting billions of dollars in venture investment. In fact, we’ve already seen some successful exits, including one from one of our panelists.

    On September 5th at TC Sessions: Enterprise, we’re going to be discussing the rise of Kubernetes with two industry veterans. For starters we have Aparna Sinha, director of product management for Kubernetes and the newly announced Anthos product. Sinha was in charge of several early Kubernetes releases and has worked on the Kubernetes team at Google since 2016. Prior to joining Google, she had 15 years experience in enterprise software settings.

  • Should Google be a bit less like Google to succeed in cloud?

    It's also very possible that it oversteps the mark. As James Urquhart put it, "Google is the Sun Microsystems of this decade. Engineering for engineering to engineer by engineering. A phenomenal approach for discovering innovative solutions, but not necessarily a great one for product-market fit." Is Google too Googley for its own good?

  • SIM swap horror story: I've lost decades of data and Google won't lift a finger

    We pay for Google Drive, Google Fi, and Google Play Movies so I was hoping there would be some level of customer service for paying customers. There are no phone numbers available for customers who pay for services or those who only use free services. Google prides itself on collecting my information and using it to help with search results. Thus, it has all sorts of information on how I conduct my daily life, including tracking my every movement, tracking my business trips, seeing who I contact daily, and much more. You would think it would be smart enough to see when some stranger appears and completely changes my account information.

    According to Gmail, my Google account has now been deleted so I'm no longer trying to just reset the password, but instead I am trying to recover my account. I have countless PR folks, friends, family, and others who are in my long Gmail history and am currently unable to access any of that information. I also have thousands of photos that may be lost forever if Google won't work with me to get my account back.

  • The Risks Of Outsourcing

    One risk that is often underestimated is that the security of IT outsourced to a cloud provider has a single point of failure, the security of the account at the cloud provider. Brian Wilson of Backblaze pointed to the risk that the account suffers a billing problem: [...]

  • Is Hadoop Dead?

    When you hear "No one needs big data", look over the CV of the speaker. An African telecoms carrier going through amazing levels of growth is not going to reach out to a greenfield JavaScript Web Developer and ask them if they could help architect their data platform and optimise their billing calculations. You might find a lot of internally-hosted web applications in an Airline's headquarters but when it comes to analysing PBs of aircraft telemetry for predictive maintenance there might not be any PHP developers on that project.

    The above projects often aren't advertised in a way that web developers would be exposed to them. This is why someone could spend years working on new projects that are at the bottom of their S-curve in terms of both growth and data accumulated and largely never see a need for data processing outside of what could fit in RAM on a single machine.

  • NZTA open sources security tool for use by other agencies

    The New Zealand Transport Agency is open sourcing a security assurance tool it is developing with Wellington company Catalyst.
    Catalyst has been working with NZTA to open source the tool that automates aspects of the security assurance process and embeds security requirements earlier in the product development life-cycle.

    The Security Development Lifecycle Tool (SDLT), aligns with common government security classifications and risk assessment practices to deliver "security by design" across the agency's tech teams.

    NZTA opted to open source the tool so other government agencies can similarly reduce their compliance overheads and focus on core delivery.

  • 5 common open source software licenses you need to know

    There are two versions of the GNU General Public License (GPL). The terms of the latest iteration, GPL version 3, are clear and readable overall; it allows open copy, redistribution and modification. Developers who use open source code covered by GPL version 3 can choose to charge a fee for their open source software.

    However, the GPL imposes several important restrictions on developers and users. The GPL emphasizes copyleft behaviors for activities such as including linking, distribution, modification and re- or sub-licensing. Generally, copyleft clauses require that uses of the work observe the same terms and conditions to which the original code adheres. Thus, open source software obtained under GPL version 3 retains those rights indefinitely. In addition, developers must include a copy of the GNU GPL with the software as it's redistributed and within the software itself. Other restrictions exist for source and binary software distributions under the GPL.

    The GNU Lesser General Public License (LGPL) provides a slightly more permissive option than version 3. The agreement, for instance, allows linking the LGPL code with code under non-GPL licenses -- a practice prohibited under GPL version 3. Consequently, developers often use LGPL when they want to allow for the use of non-GPL open source libraries, but preserve other copyleft restrictions.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
