  • Haskell, Erlang, and Frank walk into a bar and begin new project to work in Unison

    At the Strange Loop conference in St. Louis, Missouri, earlier this month, Paul Chiusano, founder of Unison Computing, gave the audience a tour of Unison, an emerging programming language designed for building distributed systems.

    Created by Chiusano, Arya Irani and Rúnar Bjarnason, Unison was inspired by Haskell, Erlang, and Frank, a trio of functional programming languages. It's an open source statically typed functional programming language and it's currently in public alpha testing.

    Chiusano, in his presentation at the conference, said Unison is based on a core technical ideal. "In Unison, we're going to identify definitions not by their name but by a hash of their content," he explained.

    Programmers commonly define functions by giving them names like "foo" or "bar." You can do that in Unison too, but the way the language keeps track of those names – which are just metadata in Unison – is by associating them with a 512-bit SHA3 content hash of the implementation of that function.

  • Webinar Recording: “10 Tools and Techniques Python Web Developers Should Explore” with Michael Kennedy

    Our friend Michael Kennedy joined us yesterday for a webinar on tips every Python web developer could benefit from. As is usual with his webinars, it was a lot of fun, very well-prepared, and packed a ton of useful information. The recording is now available as well as his repository of examples.

  • Write Better Code With Our New Advanced Functions Python Course

    Writing better code isn’t always front-of-mind when it comes to learning data science — we’re often more concerned with just getting the code to work, and making sure the analysis is sound.

    But to work as part of an effective data science team, you’ve got to be able to write code that’s readable, maintainable, testable, and debuggable, not just code that’s functional.

    That’s why we’re happy to announce we’ve just launched a new course in our Python Data Scientist path called Functions: Advanced.

    It’s an in-depth Python functions course that’s designed to show you how to write better code using functional programming. If you’re working in data — or aspire to work in data — this course covers critical skills for making your code easier to read, maintain, test, and debug.

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.
