  • Open-source tech helps companies quickly adapt during pandemic

    As the COVID-19 pandemic shakes the world, companies need to change to embrace remote work and increasingly online operations. One way to quickly adapt to these new dynamics is to use open-source tools, available for access from anywhere in the globe, according to Alan Clark (pictured), who works in SUSE’s CTO Office focusing on emerging technologies and open source.

    “Our customer sentiments are changing; their purchasing habits are obviously changing. That’s changing the services that companies need to deliver,” Clark said. “And one of the powers of open source is being able to provide that to them and deliver those services very rapidly.”

  • Zstd 1.4.5 Released With 5~10% Faster Decompression For x86_64, 15~50% For ARM64

    Facebook's compression experts responsible for Zstandard have today released Zstd 1.4.5 with more performance improvements.

    Zstandard 1.4.5 comes with faster decompression performance. On x86_64 CPUs the Zstd 1.4.5 performance benefits are in the area of 5~10%. But if you are running on Arm SoCs this time around it can be 15~50% faster. Most of the Arm decompression improvements will be on the lower end of that range but for certain SoCs under ideal conditions can be 50% faster.

  • Instaclustr CTO on open source database as a service

    Ben Bromhead: Our original vision was wildly different and, like all good startups, we had a pretty decent pivot. When the original team got together, we were working on a marketplace for high value data sets. We took a data warehouse approach for the different data sets we provided and the access model was pure SQL. It was kind of interesting from a computer science perspective, but we probably weren't as savvy as we needed to be to take that kind of business to market.

    [...]

    Our take on it [managed Cassandra as a service] is also a little bit different from some of the other vendors in that we really take a multi-technology approach. So you know, not only are we engaging with our customers around their Cassandra cluster, but we're also helping them with the Kafka cluster, Elasticsearch and Redis.

    So what ends up happening is we end up becoming a trusted partner for a customer's data layer and that's our goal. We certainly got our start with Cassandra, that's our bread and butter and what we're known for, but in terms of the business vision, we want to be there as a data layer supporting different use cases.

  • Best Chrome Extensions for Screen Capture

    Oftentimes when you are browsing the Internet, you end up finding something that appears on your computer screen that you would like to share with others. These could be as simple as a meme that hooked you in, or as important as some error message that you need in order to consult with IT. You might even need to record your screen for a demo that explains how to use a tool or complete some task.
    At times like these, it is important to have tools that help in grabbing an image or recording your screen. This is where Chrome extensions for screen capture come into play, which come packed with features that may not be present in the default Snipping Tool.

    In this article, we will be looking at some of the best Chrome extensions for screen capture.

  • 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.
