Imagine you are working on a project that includes several entities implemented as part of the system. According to the required business logic, you need to enforce specific validation rules. However, these classes are provided as a third-party dependency, which means they cannot be modified and as a result cannot be annotated directly. To tackle this scenario, we will explore a feature of the Hibernate Validator known as 12.4. Programmatic constraint definition and declaration from the documentation, and demonstrate how it can be integrated with the Spring Framework.

Efficient Transformer Attention for GenAI

Aggregated on: 2024-09-24 18:21:18

Generative AI (aka GenAI) is transforming the world with a plethora of applications including chatbots, code generation, and synthesis of images and videos. What started with ChatGPT soon led to many more products like Sora, Gemini, and Meta-AI. All these fabulous applications of GenAI are built using very large transformer-based models that are run on large GPU servers. But as the focus now shifts towards personalized privacy-focused Gen-AI (e.g., Apple Intelligence), researchers are trying to build more efficient transformers for mobile and edge deployment. Transformer-based models have become state of the art in almost all applications of natural language processing (NLP), computer vision, audio processing, and speech synthesis. The key to the transformer's ability to learn long-range dependencies and develop a global understanding is the multi-head self-attention block. However, this block also turns out to be the most computationally expensive one, as it has quadratic complexity in both time and space. Thus, in order to build more efficient transformers, researchers are primarily focusing on:

Human Introspection With Machine Intelligence

Aggregated on: 2024-09-24 13:21:18

Computational logic manifests in various forms, much like other types of logic. In this paper, my focus will be on the abductive logic programming (ALP) approach within computational logic. I will argue that the ALP agent framework, which integrates ALP into an agent’s operational cycle, represents a compelling model for both explanatory and prescriptive reasoning. As an explanatory model, it encompasses production systems as a specific example; as a prescriptive model, it not only includes classical logic but also aligns with traditional decision theory. The ALP agent framework’s dual nature, encompassing both intuitive and deliberative reasoning, categorizes it as a dual-process theory. Dual-process theories, similar to other theoretical constructs, come in various versions. One such version, as Kahneman and Frederick [2002] describe, is where intuitive thinking “swiftly generates instinctive solutions to judgment issues,” while deliberative thinking “assesses these solutions, deciding whether to endorse, adjust, or reject them.”

That pool of 400 auditions was then whittled down to the five available today. Not that it was completely smooth sailing; not when the company had to shelve "Sky" due to its striking similarities to Scarlett Johansson.

Reducing Infrastructure Misconfigurations With IaC Security

Aggregated on: 2024-09-23 20:21:18

Infrastructure as Code (IaC) became the de facto standard for managing infrastructure resources for many organizations. According to Markets and Markets, a B2B research firm, the IaC market share is poised to reach USD 2.3 Billion by 2027. What Is Infrastructure as Code? Before IaC, a developer would use the cloud provider GUI, clicking through different configurations and settings to provision a resource like a Virtual Machine. When you need to provision a single instance, this is easy, but modern workloads are more than one single machine, 1000s of VMs, and hundreds of storages — not to forget this is for one region. To achieve high availability, the same stamp needs to be created in multiple regions and availability zones. One way organizations automated this process is, through scripts, though it had challenges like versioning and, most importantly, the redundancy of each team repeatedly creating scripts from scratch.

Hoisting in JavaScript

Battle of the RabbitMQ Queues: Performance Insights on Classic and Quorum

Aggregated on: 2024-09-19 17:36:15

RabbitMQ is a powerful and widely used message broker that facilitates communication between distributed applications by handling the transmission, storage, and delivery of messages. As a message broker, RabbitMQ serves as an intermediary between producers (applications that send messages) and consumers (applications that receive messages), ensuring reliable message delivery even in complex, distributed environments. One of the core components of RabbitMQ is the queue, where messages are temporarily stored until they are consumed. Queues play a critical role in RabbitMQ’s architecture, enabling asynchronous communication and decoupling the producers and consumers. This decoupling allows applications to operate independently, promoting scalability, resilience, and fault tolerance.

Securing Your Enterprise With an Identity-First Security Strategy

Aggregated on: 2024-09-18 18:51:15

According to Fortune Business Insights, the global Software as a Service (SaaS) market is projected to grow from USD 317 billion in 2024 to USD 1.2 trillion by 2032, with a compound annual growth rate (CAGR) of 18.4%. This substantial growth in SaaS and cloud service adoption is primarily driven by modern technological advancements, such as artificial intelligence, and a predominantly hybrid workforce that requires productivity to remain competitive. However, this increased reliance on SaaS software has also led to a rise in cyberattacks. A study from the University of Maryland reveals that hackers attempt an attack every 39 seconds on average. With the emergence of AI, cyberattacks are becoming more sophisticated. With the average cost of a cyberattack nearing $4.45 million, it is crucial for enterprises to evolve their security infrastructure to protect against the evolving threat landscape posed by modern cyberattacks. Taking an Identity-First Approach to Security Malicious actors are no longer limited to targeting traditional VPN networks for unauthorized access. With the rise of remote work and organizations allowing employees to work from anywhere, attackers are increasingly targeting identities and employing modern techniques, such as social engineering attacks, to gain access to systems. According to the 2024 Verizon Data Breach Investigations Report, 68% of data breach attacks involve a human element, like a person falling victim to a social engineering attack.

Zero To AI Hero, Part 4: Harness Local Language Models With Semantic Kernel; Your AI, Your Rules

Aggregated on: 2024-09-18 17:36:15

We have covered a lot of grounds in this series so far. If you are looking to start with Semantic Kernel, I highly recommend starting with Part 1. In this AI developer series, I write articles on AI developer tools and frameworks and provide working GitHub samples at the end of each one. We have already experimented with AI Agents, Personas, Planners, and Plugins. One common theme so far has been we have used an Open AI GPT-4o model deployed in Azure to do all our work. Now it is time for us to pivot and start using local models such as Phi-3 in Semantic Kernel so that you can build AI automation systems without any dependencies. This would also be a favorite solution for cyber security teams, as they don't need to worry about sensitive data getting outside of an organization's network. But I believe the happiest would be the indie hackers who want to save on cost and still have an effective Language Model that they can use without worrying about token cost and tokens per minute. What Is the Small Language Model? Small language models (SLMs) are increasingly becoming the go-to choice for developers who need robust AI capabilities without the baggage of heavy cloud dependency. These nimble models are designed to run locally, providing control and privacy that large-scale cloud models can’t match. SLMs like Phi-3 offer a sweet spot — they’re compact enough to run on everyday hardware but still pack enough punch to handle a range of AI tasks, from summarizing documents to powering conversational agents. The appeal? It’s all about balancing power, performance, and privacy. By keeping data processing on your local machine, SLMs help mitigate privacy concerns, making them a natural fit for sensitive sectors like healthcare, finance, and legal, where every byte of data matters.

This article dives deep into the algorithms behind AI-driven search and how they enhance query processing, enabling intelligent, relevant, and scalable search experiences. From Traditional To AI-Enhanced Query Processing Traditional query processing methods, such as Boolean search and simple keyword-based matching, relied heavily on manual indexing and rigid rule-based systems. These methods often failed to capture the user’s intent or adapt to complex queries. In contrast, AI-enhanced query processing employs machine learning (ML) and deep learning (DL) models to understand the semantics of a query, providing more accurate results by interpreting the context rather than focusing solely on keyword matching.

Aggregated on: 2024-09-17 15:21:14

TL;DR: The Perils of Founder Mode This article delves into the darker aspects of Founder Mode, popularized by Paul Graham and others. It offers a critical perspective for agile practitioners, product leaders, startup founders, and managers who embrace this paradigm and probably fall victim to survivorship bias; the Jobs and the Cheskys are the exception, not the rule. The article explores how resulting tendencies, such as micromanagement, lack of strategic transparency, team devaluation, and reckless risk-taking, can undermine organizational health, stifle innovation, and conflict with agile principles. These can jeopardize long-term success while making work in organizations with a failed founder mode application miserable for everyone below the immediate leadership level and the founder himself.

Commonly Occurring Errors in Microsoft Graph Integrations and How To Troubleshoot Them (Part 6)

Aggregated on: 2024-09-16 23:21:13

This article discusses the following example: changing a column value for a list item of a “user-defined” SharePoint list, which represents a PDF file within a sub-folder of the SharePoint drive, using a DriveItem, which also represents the PDF file. SharePoint lists are central data structures that make it possible to store, organize, and manage information in tabular form. The test aims to demonstrate and explain how the MS-Graph API can be successfully used to change values in a list and correctly transfer this change to SharePoint. This ensures that the integrity of the file is maintained after the change and that no unexpected errors occur during API communication. Microsoft Graph API The Microsoft Graph API is a REST-based programming interface that provides access to a variety of services and data within the Microsoft 365 platform. It offers developers the ability to access a central interface to read, write, and manage data from services such as Azure Active Directory, Outlook, OneDrive, SharePoint, Microsoft Teams, and many more.

Observability agents are essential components in modern software development and operations. These software entities act as data collectors, processors, and transmitters, gathering critical telemetry data from applications, infrastructure, and network devices. This data is then sent to centralized observability platforms where it can be analyzed to gain valuable insights into system performance, identify issues, and optimize operations. By efficiently capturing, processing, and transmitting logs, metrics, and traces, observability agents provide a comprehensive view of system health and behavior. This enables organizations to make informed decisions, improve application reliability, and ensure compliance with relevant regulations.
