How to run MariaDB inside Docker and connect to it with Spring Boot Docker with MariaDB We’ll use yobasystems/alpine-mariadb, a lightweight container image using the open-source MariaDB as MySQL alternative. Here’s the docker command: docker run --name mariadb -p 33067:3306 -v /var/lib/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root_pass -d yobasystems/alpine-mariadb The command will create a container named mariadb with a root password (root_pass). You can connect to the database via localhost on port 33067.

I’m part of a community of self-taught developers. I’m trying to help tech newbies in the discord channel. Judging from the number of questions, new developers seem to have problems deploying static websites to GitHub pages. In this article, I’ll show you a basic way to bring your first front-end projects to life on GitHub pages. Prerequisites On your computer: Git Node.js You’ll also need a free GitHub account.

image from the Gotify website You have several devices and you want to receive notifications from your Android phone to your web browser (or vice versa). Maybe you also want to send notifications via REST API. You are a developer after all. You can think of interesting ways to send notifications. Pushbullet comes to mind, but you don’t want to sign up with Google or Facebook. You don’t want to use Google services.

Self-deployed FaaS with Docker Swarm Serverless is all the rage right now. Instead of maintaining a server and its infrastructure, you can create self-contained functions that do the job. This can be a boon for front-end developers. A bespoke front-end client written in React.js or another framework can easily be enhanced with back-end code. It’s now trivial to add a secure integration with a payment provider like Stripe.

Advanced Traefik 2 Setup with Docker Swarm, SSL Certificates and Security Options Traefik is an open-source router and load-balancer that sits in front of your web services. You can set it up to automatically encrypt your websites with SSL certificates. It’s also easy to add new web services to an existing Traefik cluster. I discovered Traefik via Jakub Svehla’s post Building a Heroku-like infrastructure for $5 a month. He shows you how to use Docker to install a Traefik infrastructure on a cheap VPS like DigitalOcean.

(image by @mamihery) Why Hy? My second programming language was a Lisp. I fell in love with the expressiveness of Lisps. But most Lisps are obscure. The ecosystem is not suited for beginners. One of younger Lisps, Clojure, was my first foray into the world of web-development. I failed spectacularly because I didn’t know how web-develoment worked, and the Clojure ecosystem assumes too much previous knowledge. Other languages, e.g., Racket, are more approachable, but are still too unpopular to have a big community.

The Zero To Mastery Deno Course deploys a Deno docker container to Amazon EC2. The EC2 instances cost money after you’ve exhausted your free 12 months. Plus, Amazon’s cloud services can be tricky. Sometimes, services spike. You quickly exceed your free tier, even for a simple toy app. Let’s deploy Deno to Heroku instead. Heroku’s free tier stays free regardless of usage. The free level is slow, because it will periodically stop to save resources.

Create a command-line tool which downloads a README template for your coding projects Why Nim? Nim is a statically typed systems programming language. Nim generates small, native dependency-free executables. The language combines a Python-like syntax with powerful features like meta-programming. Nim supports macOS, Linux, BSD, and Windows. The language is open-source and has no corporate affiliation. Nim compiles to multiple backends, for example, C, C++, or JavaScript. The ecosystem and community are small, but the language has reached its first stable release.

I’ve moved this blog from Gatsby.js to Hugo. My build times have gone down from more than 7 minutes to a few seconds! The slow build times with Gatsby have been an ongoing concern for me. I’ve slowly been creeping towards Netlify’s free 300-minutes-build-time cap. Hugo runs a magnitude faster, and it integrates well with Netlify. Hugo is a static site generator built with Golang. The project’s selling points are incredible speed, ease of use, and the ability to configure tons of settings.

UPDATE: ReasonML + BuckleScript is now Rescript. As the ecosystem has changed around those tools, this blog post is not accurate anymore. We’ve come quite far with our music player in ReasonReact. We created a React Context with state, a hook to manage the Context, and we started with our UI. In this post, we will create a component for the music player control buttons, and we will finally implement the functionality to play the track via the DOM API.
