  • How to manage a 24×7 private cloud with one engineer

    In the last several years, we have witnessed the creation of many technologies, starting with the cloud and going further to machine learning, artificial intelligence, IoT, big data, robotics, automation and much more. The more the tech evolves, the more organizations thrive to adopt these technologies seeking digital transformation and disrupting industries along their journey, all for the benefit of better serving their consumers.

    With every technology having its own requirements, costs and benefits, the only common aspect between any technology you decide to invest in is one thing: it is all based on achieving a business goal that will help your organization better position itself in the market. You might be luckily taking advantage of leading your field, or looking to better serve your customers, or even keeping up with tough competition. Whatever your motive is, the aim will always be to realise a business goal out of your investment.

  • Accessing and recovering data with a live Linux distribution [Ed: Self-promotional piece disguised thinly as 'article']

    But it’s also useful when trying to access and recover data from a failing drive. In many cases, hard drive failure and data corruption only affects a specific portion of the drive. While this renders data in that section inaccessible and, in many cases, unrecoverable, any data that is stored outside of the affected might remain intact. If your system files have become corrupted, for example, there’s a good chance that your personal files, which are hosted in a different sector on the drive, are still recoverable.

    To begin the process and find out, simply install Ubuntu onto a USB flash drive, boot your system and, when prompted, click on “Try Ubuntu.” By clicking this option instead of installing it, you’ll effectively launch a live instance of Ubuntu. Many other Linux distros support this feature in some form or another, but the method for accessing the live instance will likely vary depending on the exact distro you’re using.

    If you’re an advanced user, you’ll be able to locate the failed or corrupted hard drive in question once you’ve launched Ubuntu into your system’s RAM. From here, it’s just a matter of mounting the device within Linux and copying that data to another USB drive. For best results, try to avoid using the same drive that contains your Linux distro.

    From here, it’s just a matter of copying your data back onto a fully functional machine. While you might be missing some of your data, including whatever was stored in the failed or corrupted sectors, the majority of your information should still be available.

  • When will my instance be ready? -- understanding cloud launch time performance metrics

    Instance launch time, also called startup time, is an important performance metric for the Cloud. But what is meant by launch time? There are several related metrics that comprise launch time. In this blog post, we will describe three launch time performance metrics and explain the key components of each. Once these pieces are understood, we will describe how to build an infrastructure that measures and monitors launch time performance of cloud instances on a regular basis.

    Why is launch time important? A key reason is that clouds are elastic by nature, which means that compute instances are created and destroyed in response to changes in workload demand. Hence, the time to launch instances is a critical factor in overall workload performance. Launch time metrics also help determine lead time for making instance provisioning requests, thereby playing an important role in how effective cloud elasticity is.

  • The Bitcoin Revolution is Here | Tech Source

    Since 2014, I’ve been talking about bitcoin here (read: Is Bitcoin The Next Open-source Software Revolution?, Best Bitcoin Applications for Linux). Back then, bitcoin was still very much in its infancy and our articles about it were some of the least popular posts we’ve ever had. However, I have already seen its potential and proclaimed that it could become a revolutionary open-source software project and that it has the potential to be bigger than Linux.

    [...]

    After promoting Linux and other free and open-source software in the past, I have decided from now on to focus most of my time here in writing about bitcoin, cryptocurrencies, and other interesting blockchain projects. I think it is about time to enlighten people that bitcoin is not purely a speculative asset, but something that is more valuable because of its capability to empower people from around the world. Like most of you, I find joy in freedom and for me bitcoin is freedom. Now, I can safely say that the cryptocurrency revolution is underway, and we are just getting started.

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.
