Node.js 22.8.0 has introduced a new and significant feature for developers working with large-scale applications: a built-in JavaScript API that enables on-disk caching of all modules loaded after it is invoked. This new API, called module.enable.CompileCache(), aims to optimize the performance of applications by reducing the need to recompile modules, saving both time and computational resources. By utilizing this functionality, Node.js developers now have an easy and efficient way to manage caching for their code, which can be particularly useful for applications with complex module structures or high resource demands. Prior to this update, the only way to enable on-disk…

In Java, exceptions are a fundamental part of error handling, and they help developers manage unexpected conditions or failures that arise during the execution of a program. Essentially, an exception represents an event that disrupts the normal flow of a program. For example, when a program attempts to read a file that doesn’t exist, it throws an exception. Understanding how exceptions work in Java is essential for writing robust and fault-tolerant applications. In this article, we’ll explore how exceptions are thrown, caught, and handled, and how you can use Java’s exception-handling features to build better, more resilient software. There are…

PostgreSQL, enhanced by the pgvector extension, offers a powerful yet flexible way to use traditional relational databases for vector storage. Each vector is saved as a row, allowing developers to store both vector data and additional metadata within the same table. This hybrid approach provides a unique advantage over pure vector databases, as it combines the strengths of relational data management with the capabilities of vector search. In enterprise applications, this flexibility allows teams to handle both structured and unstructured data in a seamless manner, making PostgreSQL with pgvector an attractive choice for many developers. While pure vector databases are…

When developing generative AI applications, especially those utilizing proprietary data, it’s crucial to manage the data used to generate responses to user queries. Simply integrating a pre-trained large language model (LLM), such as ChatGPT, into your platform won’t suffice if your data wasn’t included in the model’s initial training set. Without a way to ground the AI’s responses in relevant data, it’s likely that the AI will generate plausible-sounding, yet random, text. This phenomenon occurs because the model is essentially predicting the most probable next word or phrase based on statistical patterns, which can lead to “hallucinations”—responses that sound logical…

Kong, a leading provider of API infrastructure platforms, has announced a significant update to its Kong Konnect API platform with the introduction of the Konnect Service Catalog. This new feature acts as a comprehensive system of record, offering improved visibility and control over all APIs within an organization’s IT infrastructure. The Service Catalog enables businesses to better manage their APIs, ensuring they can easily track and govern every API in use across the enterprise. With this update, Kong is reinforcing its commitment to providing a unified platform that securely supports the entire API lifecycle, from development and deployment to security…

Microsoft has officially advanced .NET 9 to the release candidate stage, bringing with it a variety of exciting new features and improvements. Among the notable updates, the WebSocket APIs have been enhanced, providing developers with greater control over connection management. This includes new options for sending WebSocket pings and aborting connections when peers fail to respond within a specified time frame. Previously, developers could only adjust the KeepAliveInterval to prevent idle connections, but this new feature offers a more direct way to enforce peer response requirements, improving reliability in real-time communication scenarios. The release candidate also introduces significant updates to…

Handling files on the server is a fundamental task for developers, and server-side JavaScript platforms like Node.js, Deno, and Bun make it relatively easy to work with files. These platforms provide various libraries and tools that streamline the process of reading, writing, updating, and organizing files. In this article, we’ll explore how to use the fs (filesystem) library in Node.js and other platforms to perform common file-handling operations, such as creating, moving, and listing files and directories, as well as streaming file data efficiently. The fs library is an essential module in server-side JavaScript, primarily used for interacting with the…

TypeScript 5.6, the newest stable version of Microsoft’s strongly typed JavaScript extension, is now available for general use. This release brings several improvements, including new rules for disallowing unnecessary nullish and truthy checks. These checks, when applied to expressions that always yield the same outcome, can now trigger compiler errors. The goal of this feature is to catch potential bugs early in the development process by flagging checks that are redundant or meaningless due to their predictable outcomes. For example, expressions like true, false, 0, and 1 are still allowed, even though they always evaluate to a specific truthy or…

Oracle has introduced its AI-powered programming assistant, Oracle Code Assist, in a beta trial. The tool is designed to enhance the development of applications on Oracle Cloud Infrastructure (OCI) and is currently optimized for Java. Oracle aims to make this assistant an essential resource for developers, particularly for those building and maintaining applications in Java. The beta version provides a suite of features intended to support developers in their efforts to boost performance, security, and efficiency when working with Java applications. While Oracle Code Assist is primarily focused on Java in its beta version, it is compatible with most modern…

Generative AI, despite its relatively recent emergence compared to other AI technologies, has already proven its versatility in supporting a variety of tasks. From helping to vet job candidates to assisting in diagnosing medical conditions and recommending treatments, its potential is vast. IDC projects that by 2028, a significant portion of chief information officers will turn to generative AI tools to enhance decision-making, improve customer service, accelerate data analysis, and more. As businesses begin to recognize the value of these tools, they are exploring ways to integrate large language models (LLMs) into their operations to enhance productivity and customer experiences.…
