Programming: micro.sth, RProtoBuf, Perl and Python

Development
  • Introducing micro.sth

    Many developers turn their noses up at PHP, but I have a soft spot for it. For me, it's the most approachable programming language by far. It feels intuitive in a way no other languages do, and it makes it possible to cobble together a working application with just a handful of lines of code. So whenever I can't find a tool for a specific job, I try to build one myself.

    The latest project of mine is a case in point. I was looking for a simple application for keeping a photographic diary, and I was sure that I'd be able to find an open-source tool for that. I searched high and low, but I came back empty-handed. Sure, there are plenty of static website generators, but I'd prefer something that doesn't require me to perform the write-generate-upload dance every time I want to post a quick update. And I need something that I can use not only to maintain a simple diary, but also store notes, manage tasks, and draft articles -- all this without getting bogged down by configuring templates, defining categories, and tweaking settings. And because I want most of my content to be private, I should be able to protect access to it with a password.

  • Dirk Eddelbuettel: RProtoBuf 0.4.17: Robustified

    A new release 0.4.17 of RProtoBuf is now on CRAN. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol.

    This release contains small polishes related to the release 0.4.16 which added JSON support for messages, and switched to ByteSizeLong. This release now makes sure JSON functionality is only tested where available (on version 3 of the Protocol Buffers library), and that ByteSizeLong is only called where available (version 3.6.0 or later). Of course, older versions build as before and remain fully supported.

  • 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.
