  • RcppArmadillo 0.9.300.2.0

    A new RcppArmadillo release based on a new Armadillo upstream release arrived on CRAN and Debian today.

    Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 583 other packages on CRAN.

  • William Lachance: New ideas, old buildings

    Last week, Brendan Colloran announced Iodide, a new take on scientific collaboration and reporting that I’ve been really happy to contribute to over the past year-and-a-bit. I’ve been describing it to people I meet as kind of "glitch meets jupyter " but that doesn’t quite do it justice. I’d recommend reading Brendan’s blog post (and taking a look at our demonstration site) to get the full picture.

    One question that I’ve heard asked (including on Brendan’s post) is why we chose a rather conventional and old technology (Django) for the server backend. Certainly, Iodide has not been shy about building with relatively new or experimental technologies for other parts (e.g. Python on WebAssembly for the notebooks, React/Redux for the frontend). Why not complete the cycle by using a new-fangled JavaScript web server like, I don’t know, NestJS? And while we’re at it, what’s with iodide’s ridiculous REST API? Don’t you know GraphQL is the only legitimate way to expose your backend to the world in 2019?

    The great urban theorist of the twentieth century, Jane Jacobs has a quote I love:

  • Getting started with the updated VS Code Yeoman extension for Camel projects
  • Plot the Aroon Up and the Aroon Down lines with Python

  • 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.
