I struggled with two aspects of software development as a junior engineer: structuring large codebases and writing testable code. Test-driven development is such a common technique that is often taken for granted, but it's not always clear how code can be made fully testable. I remember reading examples where an author would cleanly unit test a function, and in principle, it made sense. But real code doesn't look like those examples.

Most applications need background jobs for mailers, regular clean-ups, or any other time-consuming operation that doesn't require a user to be present. Several gems support job queues and background processing in the Rails world — Delayed Job and Sidekiq being the two most popular ones. In this post, we will take a detailed look at Delayed Job and Sidekiq, including how they fare against each other. Let's go!

In this chapter, we'll give you a kickstart introduction to effectively using package.json with Node.js and npm. The package.json file is core to the Node.js ecosystem and is a fundamental part of understanding and working with Node.js, npm, and even modern JavaScript. This file is used as a manifest, storing information about applications, modules, packages, and more.

According to EY Global’s Consumer Insurance Survey, 87% of policyholders say the claims experience directly impacts their decision to remain with their insurance provider. To up the ante even further, insurtech funding has been increasing exponentially.

Businesses have been adopting more apps over the last decade. The right applications make it easier for them to communicate with customers, analyze data, improve efficiency, and refine their business practices. The number of apps used by businesses jumped incredibly during 2020 as the pandemic made it more difficult or impossible for employees to work from their offices. As organizations rely more heavily on diverse applications, they need reliable API management tools with self-service features.

It’s fair to say that the pandemic has not only wreaked havoc on how individuals live their daily lives but also on how they work. The global changes led to an immediate shift to remote working and unfortunately, not all enterprises were prepared for it. Companies did not have adequate time to prepare and allocate necessary security resources to ensure strong network and device protection for employees working remotely.

The SecurityException is a runtime exception in Java that is thrown by the security manager to indicate a security violation. The SecurityException is an unchecked exception and does not need to be declared in the throws clause of a method or constructor.
