Determine the “Readability” of a text with Python

George Klare (1963) defines readability as “the ease of understanding or comprehension due to the style of writing.” Readability, although somewhat subjective, has been a well researched topic dating back to the 1920s. Since then, researchers have crafted a number of readability formulas that attempt to accurately identify the readability of a text. Readability metrics have numerous uses. A writer might use the metrics to objectively assess the complexity of...

Awesome APIs with Kotlin, Spring 5 and Swagger

Early last year, Spring announced official support for Kotlin in Spring Framework 5. The news was welcome and exciting, particularly with respect to technologies like Spring Webflux, Project Reactor, and Spring functional, areas where Kotlin very much shines. In this article, I will describe how to bootstrap a new Spring 5 project that integrates Kotlin, Spring Webflux functional, Project Reactor, Swagger, Gradle, and JUnit using kotlin-swagger-spring-functional-template. The template includes two sample REST...

There are numerous benefits to microservice architectures, however configuring each service can be quite complex. Each framework may offer their own configuration method e.g. property files, yaml, json, etc. As the number of microservices pile up, this quickly becomes a dev...

Node.js / Express app generator: with ES.next, API validation, documentation, logging, and more

[Take me to the app generator] I’m at work on a new project. My team and I are building a highly scalable service platform and have elected to build it using the microservices architecture pattern. The platform consists of many microservices, each of which is typically owned by a collaborating team. Teams are empowered to make decisions and choose technologies that best fit the need. This means that services may...

Create a custom React Native module that exports Constants (with Swift)

In this post, we will create a simple React Native module using Swift. The module will return information about the current device and expose it to JavaScript. First, we create our Swift class, RNDevice.swift. This class will is responsible for returning information that describes the current device. This information is obtain using the UIDevice class. Next, we create the bridge to React Native and externalize the RNDevice class (above), so...

Create a self signed certificate with OpenSSL

To create a self signed cert with OpenSSL, execute the following: openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 100 In some cases its useful to remove the passphrase from the key. This way you will not be prompt for the passphrase every time it starts. Removing the passphrase is easy, simply run this following command: openssl rsa -in key.pem -out newkey.pem && mv newkey.pem key.pem

Adapt jQuery.getJSON to an Rx.Observable with RxJs

Rx provides an incredible and fluent API to help untangle your asynchronous JavaScript code. Here we’ll see how to adapt jQuery’s getJSON method to an Rx Observable with only a small bit of code. Now that $.getJSON has been adapted to an Observable, we can full take advantage of all the goodness that Rx provides. For example, let’s ask Rx to automatically retry the request if it fails! I’ve also...

Asynchronous programming with Async / Await and the Scala Play Framework

Asynchronous programming has a number of advantages, most notably is its well touted ability to improve responsiveness. Asynchronous events occur independently of the main program flow and asynchronous actions are executed in a non-blocking, lock-free manner. This, ultimately, allows the main program flow to continue unimpeded, without blocking. On the flips side, asynchronous programming can be difficult to reason about. Many actions are often run simultaneously which can lead to...
