While an earlier version of Hibernate had support for multi-tenancy, its implementation required significant manual configuration and custom strategies to handle tenant isolation, which resulted in higher complexity and slower processes, especially for applications with a number of tenants. The latest version of Hibernate 6.3.0, which was released on December 15, 2024, addressed the above limitations with enhanced multi-tenancy support through better tools for tenant identification, schema resolution, and enhanced performance for handling tenant-specific operations. This article talks about how Hibernate 6.3.0 enhanced the traditional multi-tenancy implementation significantly.

It is a space-efficient, highly probabilistic data structure that every developer should be familiar with. It can significantly speed up exact match queries, especially in cases where indexing has not been added to that field. The space efficiency of a Bloom filter provides the added advantage of allowing filters to be created for multiple fields. How It Works Reading from a database or storage is a costly operation. To optimize this, we use a Bloom filter to check the availability of a key-value pair and only perform a database read if the filter responds with a 'Yes.' Bloom filters are space-efficient and can be stored in memory. Additionally, the lookup test for a value can be performed in O(1) time. More on this later. Let’s explore this concept with an example: View more...Powering LLMs With Apache Camel and LangChain4jAggregated on: 2025-01-23 14:32:20 LLMs need to connect to the real world.

To extend the knowledge retrieval-augmented generation (RAG) can be used that retrieves relevant information from a vector database and adds it to the prompt context. To provide really up-to-date information, function calls can be used to request the current information (flight arrival times, for example) from the responsible system. That enables the LLM to answer questions that require current information for an accurate response. The AIDocumentLibraryChat has been extended to show how to use the function call API of Spring AI to call the OpenLibrary API. The REST API provides book information for authors, titles, and subjects. The response can be a text answer or an LLM-generated JSON response. For the JSON response, the Structured Output feature of Spring AI is used to map the JSON in Java objects.

We've all struggled with the inconsistent naming of variables across files, trying to recall exactly what function signature was defined months ago, and wasted valuable hours manually stitching pieces of our codebase together. This is where large language models (LLMs) come in — not as chatbots, but as strong engines in our IDEs, changing how we produce code by finally grasping the context of our work. Traditional code generation tools, and even basic features of IDE auto-completion, usually fall short because they lack a deep understanding of the broader context; hence, they usually operate in a very limited view, such as only the current file or a small window of code. The result is syntactically correct but semantically inappropriate suggestions, which need to be constantly manually corrected and integrated by the developer. Think about suggesting a variable name that is already used at some other crucial module with a different meaning — a frustrating experience we've all encountered.

Developers either invoke APIs directly or write code in the form of functions, and the cloud provider executes these functions in response to certain events. This means developers can scale applications automatically without worrying about server management and deployments, leading to cost savings and improved agility. The main advantage of serverless computing is that it abstracts away much of the complexity related to release management, and developers don’t need to worry about capacity planning, hardware management, or even operating systems. This simplicity frees up time and resources to focus more on building innovative applications and services on top of the deployed models.

Sustainable software development, I've come to realize, is little more than a buzzword. It's an overarching philosophy that informs how we write code, structure projects, and think about the future. Initially, I was lured by the excitement of delivering new features rapidly. But after seeing those same shortcuts morph into technical debt, I changed my approach: code that merely "works" today is not enough; it needs to remain robust and maintainable for years to come. Throughout this article, I'll share my firsthand experiences and the principles I've adopted for sustainable development. We'll talk about the real cost of quick fixes, the importance of simplicity in code, the technical tools and techniques that keep quality high (like Git, SonarQube, and automated testing frameworks), and the practices, such as code reviews and refactoring, that help us pay down technical debt before it spirals out of control. If there is one underlying theme to all this, it's that "less is more." Focusing on quality over quantity, and keeping our code lean, maintainable, and tested, we can solve problems not only for now but for the future.

Solution To resolve this issue, grant the required privileges to the user from the MySQL command line: View more...Chain-of-Thought Prompting: A Comprehensive Analysis of Reasoning Techniques in Large Language ModelsAggregated on: 2025-01-20 13:32:18 Chain-of-thought (CoT) prompting has emerged as a transformative technique in artificial intelligence, enabling large language models (LLMs) to break down complex problems into logical, sequential steps. First introduced by Wei et al. in 2022, this approach mirrors human cognitive processes and has demonstrated remarkable improvements in tasks requiring multi-step reasoning[1]. CoT: Explanation and Definition What Is CoT? Chain-of-thought prompting is a technique that guides LLMs through structured reasoning processes by breaking down complex tasks into smaller, manageable steps. Unlike traditional prompting, which seeks direct answers, CoT encourages models to articulate intermediate reasoning steps before reaching a conclusion, significantly improving their ability to perform complex reasoning tasks [1].

Not raw computational power, but something that seems almost contradictory: being neurotically careful about being right. When AI researchers talk about mathematical reasoning, they typically focus on scaling up — bigger models, more parameters, and larger datasets. But in practice, mathematical ability isn’t about how much compute you have for your model. It’s actually about whether machines can learn to verify their own work, because at least 90% of reasoning errors come from models confidently stating wrong intermediate steps.

The vision was exciting and broad but indefinite. And, it sparked concerns — serious ones. In this article, we describe a definite (in fact, running) vision for such a system and how to deal with reasonable concerns raised in the comments.

The process, results, and overall experience turned out to be fascinating, so I hope you find this story interesting and, perhaps, even inspiring. After all, I taught my project how to understand spoken commands and do exactly what I want. This story might spark new ideas for you, encourage your own experiments, or even motivate you to build a similar project. And of course, I'd be thrilled if you join me in developing ConsoleGpt — whether by contributing new features, running it locally, or simply starring it on GitHub. Anyone who's ever worked on an open-source project knows how much even small support means. View more... |
