  • 10 Factors Behind the Popularity of Microservices: Part 2

    I have shown in this series that microservices happily bring together several trends in computing from the past couple decades. There are many precedents for each of the traits developers associate with microservices. And these programming tools and processes are sure to evolve further. Microservices may soon join many of the other terms in this article that once larded programmers' discussions, only to be denigrated later as obsolete. But the historic role played by microservices will continue to be recognized.

  • Staying Sane in ML: Fixing Your Terrible Data Science Tools to Improve the Research Experience

    While machine learning research has made incredible theoretical advances, the day-to-day tools most researchers use are… poorly optimized, to say the least. And much knowledge is locked up in people’s private .bashrc files or wikis. This post aims to shed light on some very useful tools for beginning researchers.

    Expected audience: people, likely undergraduates, who are starting to do CS research that is vaguely in the “AI/ML” space. You have joined a Slack and gotten authentication credentials for this thing called a “cluster,” and are probably using Python with Jupyter Notebook.

  • What’s Next for Object-​Oriented Perl?

    Overall I’m satisfied with Object::Pad and by extension some of the syntax that Corinna will introduce. I’m going to try porting the rest of dbcritic and see if I can work around the issues I listed above without giving up the kwalitee improvement tools I’m used to. I’ll post my find­ings if I feel it merits another blog.

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.
