News AggregatorHow to Enable Sybil Resistance in Your dApps on AvalancheAggregated on: 2025-02-19 22:42:43 If there’s one thing Web3 devs can agree on, it’s that Sybils suck. Bots and fake accounts are ruining airdrops, gaming economies, DAOs, and DeFi incentives. Everyone’s trying to fight them, but the solutions are either too centralized and non-private (KYC) or too easy to game (staking-based anti-Sybil tricks). That’s where Biomapper comes in handy — an on-chain tool that links one EVM account to one human for verifying that users are real, unique humans without KYC or exposing personal data.

In the realm of Agentic RAG, this conventional method of relying on a monolithic model for tasks has been enhanced by introducing modularity and autonomy. By breaking down the problem-solving process into tools integrated within an agent, Agentic RAG provides benefits like accuracy, transparency, scalability, and debugging capabilities. The Vision Behind Agentic RAG for Text-to-SQL Traditional RAG systems often retrieve relevant documents and rely on a single monolithic model to generate responses. Although this is an effective method in some cases, when it comes to structural outputs like the case of generating SQL, this approach may not be the most effective. This is where we can leverage the power of the Agentic RAG framework, where we: View more...Implement Amazon S3 Cross-Region Replication With TerraformAggregated on: 2025-02-18 18:42:42 With the information technology element finding its roots in every financial organization and across all industries, strong storage capacity forms the backbone for availability, durability, and scalability. Among these, Amazon S3 is one of the most popular services to meet these needs. As enterprises expand geographically, the need for data replication between locations starts to be felt significantly. Hence, the need arose to develop Cross-Region Replication in Amazon S3, where data replication between one bucket sourced from one AWS region to another bucket in a different AWS region is allowed. The article will describe how to configure Cross-Region Replication in Amazon S3 using Terraform, an IaC software.

We are collaborating with AI engineers to create tools that software engineers can easily use. Merging these two disciplines is essential to mastering tools and integrating them into our information system effectively. This approach draws heavily on software architecture analogies and focuses on integrating advanced LLM techniques, such as Chain-of-Thought (CoT) prompting, ReAct, Toolformer, and modular AI design principles.

We will build an application to upload a PDF and then do Q&A queries on it. Q&A can be done on both text and visual elements of the PDF. We will not extract text from the PDF; instead, we will treat it as an image and use ColPali to get embeddings for the PDF pages. These embeddings will be indexed to Milvus, and then we will use a VLM to do Q&A queries on the PDF pages.

From simple web searches to complex enterprise knowledge management systems, search technology has evolved dramatically to meet growing demands. This article explores the journey from index-based basic search engines to retrieval-based generation, examining how modern techniques are revolutionizing information access. The Foundation: Traditional Search Systems Traditional search systems were built on relatively simple principles: matching keywords and ranking results based on relevance, user signals, frequency, positioning, and many more. While effective for basic queries, these systems faced significant limitations. They struggled with understanding context, handling complex multi-part queries, resolving indirect references, performing nuanced reasoning, and providing user-specific personalization. These limitations became particularly apparent in enterprise settings, where information retrieval needs to be both precise and comprehensive.

IaC also increases the deployment rate and is significant when applied with cloud resources. "IaC at scale" means using this approach for massive cloud infrastructures, for thousands of resources in single or multiple environments. That is why adopting IaC to scale up its use brings into focus the aspects of agility, efficiency, and consistency in the infrastructure. However, it also creates problems regarding the organization of the dependencies and the coordination of the configurations that are to be in place across several resources.

A particularly pressing challenge is balancing hardware memory constraints with the expanding size of ML models while maintaining high performance and cost-effectiveness. This article explores an innovative architectural solution that addresses these challenges through a hybrid approach combining shared neural encoders with specialized prediction heads. The Challenge: Memory Constraints in ML Model Deployment Traditional machine learning deployments often require loading complete models into memory for each distinct use case or customer application. For example, in natural language understanding (NLU) applications using BERT-based models, each model typically consumes around 210-450 MB of memory. When serving thousands of customers, this leads to significant scaling challenges. A typical server with 72 GB of CPU memory can only support approximately 100 models simultaneously, creating a hard ceiling on service capacity.

These models, trained on vast corpora of text and optimized for predictive linguistic tasks, have demonstrated substantial efficacy in responding to queries, summarizing textual content, and generating contextually relevant information. However, despite their impressive generative capabilities, LLMs do not inherently resolve the complexities of search and retrieval in structured and unstructured data landscapes. Instead, they require augmentation with advanced techniques such as semantic chunking, vector embeddings, and context-aware personalization to optimize precision and recall.

Most of the stream processing applications are ‘stateful.’ This means the state is stored and used for further processing. In Apache Flink, the state is managed through a configured state backend. Flink supports two-state backends in production. One is the HashMapStateBackend, and the other one is the EmbeddedRocksDBStateBackend. To prevent data loss and achieve fault tolerance, Flink can persist snapshots of the state to a durable storage. Flink can be configured to snapshot either the entire state into a durable location or the delta since the last snapshot. The former is called full checkpoint, and the latter is known as the incremental checkpoint.

Finally, I will give some tips on migrating from POM to PT in simple steps. To those who are not familiar with POM, in a nutshell, it is a design pattern used in testing automation where the objects on a UI page are represented as methods in a class and where each class represents the UI page itself.

When these failures occur, they can lead to delays, incomplete transactions, or inconsistent data states, ultimately impacting the user experience and system reliability. When a system experiences a failure, clients often retry requests to ensure the operation completes successfully. However, without proper handling, retries can result in unintended consequences such as duplicate transactions, data corruption, or inconsistent states. Implementing idempotency in a system or API ensures that retries following such failures are processed reliably, maintaining the integrity and consistency of the system.
