In the first part of this series, we set up a basic Rack app, learned how to process a request and send a response. In this post, we'll take over connections from Rack and hold persistent connections to enable pathways such as WebSockets. First, though, let's look at how an HTTP connection actually works.

Serverless technology allows you to build and deploy efficient, scalable, and modern web applications. By going serverless, you can eliminate the need for server management and save time and money. In this tutorial, you'll learn how to utilize the power of serverless by building a full-stack web application using different technologies. If you are ready to take your web development skills to the next level and build a serverless web application, let's get started!

The evolution of baggage handling has long been a complex challenge for airports, airlines, and travelers alike. With millions of bags processed daily worldwide, ensuring each reaches its destination efficiently and securely is critical for passenger satisfaction and operational efficiency.

Security is critical for any application, especially when dealing with sensitive data like financial records or user information. Databases such as MongoDB and PostgreSQL communicate over the network, making them vulnerable to interception. SSL (Secure Sockets Layer) encrypts the communication between the client and the database server to prevent data exposure. This encryption ensures that: 1. Data Integrity: No third party can modify the data in transit. 2.

When you’re a popular name in the payment gateway market, like Stripe, you need to maintain a reputation for intelligent payment processing as well as strict payment security. Customers expect proactive fraud prevention and compliance management features to be inherently included in your offerings. Failing to do so will harm your brand, and you might not even get two more strikes to reaffirm your presence.

If you are looking to add intelligent test automation to your testing processes: AI agents are the answer. Unlike traditional testing tools, which depend on static programming scripts or fragile locators, AI agents learn and evolve with the software they test. That is why they are highly effective in dynamic environments. As a result, AI agents have an important role in maintaining software quality in Agile and DevOps workflows.

Node.js is a powerful runtime environment that allows you to handle asynchronous I/O operations efficiently using its event-driven architecture. Asynchronous operations in Node.js rely heavily on the event loop, and understanding how certain functions like process.nextTick() and setImmediate() interact with the event loop is essential for building fast, responsive applications.

Raw data from IoT devices, like GPS trackers or electronic logging devices (ELDs), often lacks meaning on its own. However, if combined with information from other business systems, such as inventory management or customer relationship management (CRM), this data can now provide a richer, more complete picture for more effective decision-making. For example, combining GPS data with inventory levels can optimize logistics and delivery routes.
