The Principles of Test Automation

The word “test”  originally referred to “a small vessel used in assaying precious metals.” This meant that testing was a method of ascertaining the quality of gold or silver. It was also used in the process of refining valuable alloys, such as tin.

Later, the term was adopted in other fields, and these days it’s common to find it in contexts such as education, medicine, or software development. Its essence, however, has not changed: testing is used to refine end value.

Choose the Right Model: Comparing Relational, Document, and Graph Databases

What exactly is a database model? A database model is nothing more than the structure a database developer has chosen to store information. A database model also spells out the relationships between different parts of the dataset, and any limitations that may restrict read or write access.

Individual databases are designed based on the rules and concepts of the broader data model the designers adopt. Developers often use these models to strategically design databases for larger-scale real-world projects such as:

Importance of Transit Gateway in Anypoint Platform

Introduction

Anypoint Platform is multitenant integration platform as a service and it is used for wide use cases. MuleSoft introduce and keep enhancing the Anypoint Platform and recently they have added Transit Gateway as a part of Anypoint Platform. 

Transit Gateway acts as a Cloud Router in AWS and simplify the network access between VPC's, on premise data centers and third party software. It generally merge the on premise and cloud network into single network topology. You can add multiple transit gateway in your Anypoint Organization and that is completely depends on number of the Transit Gateway entitlement with your organizations.

To create Transit Gateway on Anypoint Platform, Anypoint Virtual Private Cloud and AWS Transit Gateway must exists in the same region. One of the main advantage of the Transit Gateway to simplify the network topology and merge all the network (On Premise or Cloud) to act as a single network topology.

With AWS transit gateway, you can connect on premise, cloud resources and also establish the connection with Direct connect and using Anypoint Transit gateway within Virtual Private Cloud you can connect AWS transit gateway.

Rust’s Vector

I'll be honest: I initially wanted to describe all collections available in Rust as well as their related concepts. Then, I started to dig a bit into it, and I decided it would have been (much) too long. For that reason, I'll restrict the scope to the Vec type.

diceroller, A Sample Rust Project

For me, the best learning process is regularly switching between learning and doing, theory and practice. The last post was research; hence, this one will be coding.

I've been a player of Role-Playing Games since I was 11. Of course, I've played Dungeons & Dragons (mainly the so-called Advanced Edition), but after a few years, I've taken upon Champions and its HERO system. The system is based on points allotment and allows virtually everything regarding a character's abilities. For a brief description of the system, please check this brilliant albeit brief Stack Exchange answer. I've developed a sample application to handle (a part of) the damage generation subsystem for this post.

A Rust Controller for Kubernetes

To teach myself Kubernetes in general and controllers in particular, I previously developed one in Java. This week, I decided to do the same in Rust by following the same steps I did.

  1. My First Cup of Rust
  2. My Second Cup of Rust
  3. The Rustlings Exercises - Part 1
  4. The Rustlings Exercises - Part 2
  5. Rust on the Front-End
  6. A Rust Controller for Kubernetes (this post)

The Guiding Principle

The guiding principle is creating a Kubernetes controller that watches pods' lifecycle and injects a sidecar into them. When Kubernetes schedules the pod, the controller schedules the sidecar; when it deletes the former, it deletes the latter as well.

Data Normalization Cover

What is Normalization?

Normalization in a database is the process of organizing the data to reduce redundancy. The main idea is to segment a larger table into smaller ones and connect them through a relation.

But why should an end-user like you or me be concerned about Data Normalization?

Rust on the Front-End [Video]

Up until now, JavaScript has been the only ubiquitous language available in browsers. It has made JavaScript much more popular than its design (and its associated flaws) would have allowed. Consequently:

  • The number of JavaScript developers has grown tremendously and steadily,
  • The ecosystem around front-end JavaScript has become more extensive and much more complex,
  • The pace of changes has increased so that developers complain about JavaScript fatigue,
  • Interestingly enough, JavaScript sneaked on the back-end via Node.js,
  • etc.

I don't want to start a holy war about the merits of JavaScript, but IMHO, it only survived this far because of its role in browsers. In particular, current architectures move the responsibility of executing the code from the server to the client. It puts a lot of strain on the latter. There are not many ways to improve performance: either buy more powerful (and expensive!) client machines or make the JavaScript engines better.

My First Cup of Rust

It all started with an informal chat with my friend Anthony. We were talking about languages, and I said that I preferred compiled ones. He then went on to mention Rust. We admitted that we were too afraid to learn it because of its perceived complexity.

After the chat, I thought about it, and I wondered why I didn't check by myself. I did. And I became interested.

How to Use GitBook for Technical Documentation

For the past three months, I have had the distinct pleasure of working as an intern for an open-source project called Intermine, where I was tasked with creating new user training documentation. For this project, I entirely rewrote the Intermine user documentation — which included images, code snippets, tables, mathematical formulas, and more — using GitBook. This guide will share my experience creating technical documentation using GitBook and act as a de-facto quick-start guide to GitBook.

What is GitBook?

GitBook is a collaborative documentation tool that allows anyone to document anything—such as products and APIs—and share knowledge through a user-friendly online platform. According to GitBook, “GitBook is a flexible platform for all kinds of content and collaboration.” It provides a single unified workspace for different users to create, manage and share content without using multiple tools. For example:

How to Get the URL of Images You Upload in WordPress

Do you want to find the link or URL of images you upload in WordPress?

Sometimes you may need to get the link of an image to display it in other areas of your website or social media platforms.

In this article, we will show you how to easily get the URL of images that you upload to your WordPress site.

How to Get the URL of Images You Upload in WordPress

Finding a WordPress Image URL – Step by Step

WordPress automatically creates a unique URL for each image you upload to your website using the default WordPress media uploader.

Usually, a WordPress image URL includes your domain name followed by /wp-content/uploads/, date of image upload, and the image file name.

For example, an image named ‘travelaccessories.png’ uploaded to example.com in January 2019 will have a URL like this:

www.example.com/wp-content/uploads/2019/01/travelaccessories.png

Now let’s take a look at how to get the URL of images uploaded to your WordPress site.

First, you need to login to your WordPress admin area and click on the Media menu. Once done, it will open your media library where all your images and other media files are stored.

Next, you can use the search feature to find the image that you want to find the link of.

Search Image in WordPress Media Library

Once you click on the image, it will open a popup window with the image attachment details. You will see the image details in the right column and image preview on the left.

The right column displays all image details including file name, file type, upload date, file size, dimensions, and image metadata like image alt text, title, caption, description, image uploaded by, etc.

You will also see the image URL at the end. It is the link next to ‘Copy Link’ option.

You can simply copy the link and use it anywhere you like.

If you open the image URL in your browser, then you can see the full size original version of the image uploaded.

Finding Your WordPress Image URLs from the Frontend

The method shown above lets you get the URL of any image uploaded in WordPress, whether it is published live or not.

If you want to get the URL of images already published on your site, then you can get it from the frontend itself. It is much easier!

Open a page or post where the image is published and locate the image. After that, right-click on the image, and select ‘Open image in new tab’ option.

Open WordPress Image in a New Tab

Once the image opens in the new tab, look at the URL in the address bar. That is your WordPress image URL.
