In this tutorial, I’ll demonstrate how to leverage Vue’s reactivity to build a filterable table. This will only display the rows that match whatever text a user has entered into a text input. I’ll also show you how to highlight the matches.
This might be useful to help users quickly find what they are looking for in a long table. Once you have understood how it works, you can easily adapt it to lists or anything else you need to filter.
In this post I’ll show you how to install Ubuntu 18.04.3 LTS (Bionic Beaver) on Oracle’s VirtualBox. I’ll also demonstrate how to connect to the Ubuntu instance via SSH. This will form the basis for a second tutorial that will walk through installing and configuring Ruby on Rails on an Ubuntu server.
In this article, I’m going to demonstrate how to get up and running with NodeGUI. We’ll set up a development environment, take a look at several of the library’s basic concepts, then finish off by creating a simple password generator app.
I have an old Sony XPeria S phone (from 2012) which has long since been abandoned by my carrier. It no longer receives any updates and is stuck on Android 4.2, which kinda sucks….
So I decided to take matters into my own hands and get an up-to-date version of Android, by flashing the phone with a custom ROM. While this didn’t prove to be that difficult, I did hit a few stumbling blocks along the way, which I wanted to document.
This post will serve two purposes. Firstly, it will provide detailed instructions on how to install a custom ROM on an Xperia S. Secondly, it will also outline the general process of flashing an old Android phone and offer a high-level overview of the concepts involved.
In this tutorial I am going to demonstrate how to build a JSON API using Ruby on Rails and then code a fully-functional React frontend to interact with the API. The app we’ll be building is an event manager, which will let you create and manage a list of academic events.
Running Apache on my local machine helps me speed up my web development work. It means that I can use root-relative urls, server-side programming languages (such as PHP) and interface with a database — all without having to upload anything via FTP.
The only problem comes when you are working on multiple projects at the same time. If you create different directories for different projects within your web root (which defaults to /var/www/html), then the root-relative urls will break, as will any server-side includes you are using.
This is where virtual hosts come in. They allow you to create a separate domain for each of your projects, such as http://project1/ and http://project2/.
I’ve spent all day trying to get Devise and nested attributes to play nicely together. This and giving the user the ability to update parts of their profile without providing a password proved kind of tricky. Here’s how I got things working.
This is a beginner level tutorial on how to set up authentication (verifying who you are) and authorization (what you are permitted to do) using Ruby 2.2, Rails 4.2 and two popular Ruby gems: Devise and cancancan.
Recently, I had to reinstall my operating system (upgrading to Mint 17.1) and decided to give the rbenv installation process another try. I’m happy to say that it worked entirely as expected and within a matter of minutes I had two Ruby versions installed on my system and could switch between them at will.
