When you publish a message to Ably Pub/Sub, you can be confident that the message will be delivered to subscribing clients, wherever they are in the world. Ably is fast: we have a 99th percentile transmit latency of <50ms from any of our 635 global PoPs, that receive at least 1% of our global traffic. But being fast isn’t enough; Ably is also dependable and scalable. Ably doesn’t sacrifice data integrity for speed or scale; it’s fast and safe.

Strings are important concepts in programming and are data types that allow storage of character sequences. String methods are built-in functions that are called on a string to either get information or manipulate data. In Java, strings are treated as immutable data, therefore their values cannot be changed. To work with strings and perform operations on them, you need to understand string methods in Java and how they work.

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!

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.

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.

When running tests, it's a great feeling to see dozens of green check marks indicating that a test suite is passing. It's especially gratifying after tackling a tricky bug or slogging through a tough feature. But those passing tests may be giving you a false sense of security. Often, bugs lurk in passing tests, undermining trust in the test suite and your application. Such tests can cause more harm than good, giving you a hearty pat on the back while hiding broken functionality.

This is one of a series of posts that explain Ably’s four pillars of dependability. The four pillars project at Ably is about making concrete, objectively verifiable, statements about the technical characteristics of the service. We aim to ensure that our claims about service performance are expressed clearly in terms of explicit metrics, and we explain in technical terms how those performance levels are met.

This year, Apple Intelligence will be available in beta. It's a set of artificial intelligence features that Apple will add to macOS, iOS, and iPadOS devices to offer consumers a more personalised experience designed to help improve their efficiency and productivity. There's a lot of excitement around what Apple Intelligence will bring to developers, consumers, and the ecosystem as a whole. You can read more about the possibilities our CEO believes it will unlock here.

In the digital age, we interact with countless applications, whether for personal, professional, or recreational purposes. Many of these applications appear consumer-oriented but are, in fact, business-to-business (B2B) applications. For example, when accessing healthcare services, payroll systems, or school management platforms, you are likely using applications where your provider (such as your GP or employer) is a business customer of a larger B2B application.
