  • Six Hot Linux Certifications for 2019

    Linux, the most widely-used open source operating system (OS), dominates the web server market. According to IDC, commercial and non-commercial Linux deployments in the worldwide enterprise segment registered considerable growth in 2017. It is now the standard for enterprise applications.

  • Linux: Cornerstone For Software-Defined Infrastructure

    Linux is ever more prevalent in SAP and non-SAP environments. Recent figures, published by IDC, are testimony to record sales numbers. In fact, the majority of systems already come with Linux pre-installed.

    Moreover, Linux has long since established itself in SAP environments. The shift from Unix to Linux of NetWeaver-based system with Any-DBs, the Hana consolidation and the use of Hana-based SAP applications contributed to the almost fixed position of Linux.

  • Why Replace Windows® Server?

    Linux powers the servers that run 96.5% of the top web domains in the world (W3Cook) – and for good reason. Like moving to the cloud, swapping your Windows Server for a Linux one can save a tidy sum on your budget. You can say goodbye to licensing costs (i.e. CALs). Besides, many admins simply prefer working with Unix-based operating systems and many would argue Linux is more scalable and performant.

  • Security Considerations for Container Runtimes
  • Measuring container security

    There are a lot of claims regarding the relative security of containers versus virtual machines (VMs), but there has been little in the way of actually trying to measure those differences. James Bottomley gave a talk in the refereed track of the 2018 Linux Plumbers Conference (LPC) that described work that targets filling in that gap. He and his colleagues have come up with a measure that, while not perfect, gives a starting point for further efforts.

    Bottomley introduced himself as a "container evangelist" for IBM. He used to help convert businesses to becoming part of the open-source community. Working at Parallels on that is how he got involved with containers. He is also a kernel developer and maintainer.

  • A Container Hacker’s Guide to Living Off of the Land

    Sometimes as a pentester you find yourself in tricky situations. Depending on the type of engagement, you might want to try to avoid making a lot of noise on the network if possible. This blog post is going to talk about two techniques to use to gather information on your target while avoiding making too much noise as they pertain to container hacking. But for these to be useful, some other things have to have happened first.

  • Kubernetes in 2019: 6 developments to expect

    Plenty of emerging technologies get hyped. Few seem to gain the tangible kind of enthusiasm and traction that Kubernetes has enjoyed to this point. 

    Yet for all of the attention paid to the container orchestration tool, widespread usage is really just beginning. Kubernetes resides at an increasingly high-traffic intersection of legacy and modern software development. So expect 2019 to include a mix of Kubernetes-related trends as more and more companies see Kubernetes as a signpost indicating that turn toward “modern” is imminent. 

    Here are six particular developments to anticipate in the new year.

  • Why moving from a monolithic architecture to microservices is so hard, Gitlab’s Jason Plum breaks it down [KubeCon+CNC Talk]

    Last week, at the KubeCon+CloudNativeCon North America 2018, Jason Plum, Sr. software engineer, distribution at GitLab spoke about GitLab, Omnibus, and the concept of monolith and its downsides. He spent the last year working on the cloud native helm charts and breaking out a complicated pile of code.

    This article highlights few insights from Jason Plum’s talk on Monolith to Microservice: Pitchforks Not Included at the KubeCon + CloudNativeCon.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
