Agents and P2P NetworksJames Salter
油
Peer-to-peer (P2P) networks allow nodes to directly interact and share resources without a central authority. They can be purely decentralized, hybrid models with some centralized nodes, or structured models that organize resources. Early systems like Napster and Gnutella demonstrated P2P for file sharing but had scalability issues. Newer distributed hash table approaches like Chord provide efficient lookup of resources with only local routing information. Agents and P2P networks can enhance each other by allowing agent collaboration over decentralized networks and using agents to improve organization and coordination in P2P systems.Illuminating Lucene.Net

Elasticsearch is a distributed, open source search and analytics engine based on Apache Lucene. It allows storing, searching, and analyzing big volumes of data quickly. Elasticsearch uses an inverted index to search text, and indexes documents into shards and replicas for scalability and fault tolerance. Write operations in Elasticsearch are logged in a transaction log and memory buffer before being flushed to segments on disk. Updates create a new version rather than modifying documents in place. Reads are routed to shards, sorted, and returned to the client from the coordinating node.Ad

In today's world, artificial intelligence (AI) is transforming the way we learn.
This talk will explore how we can use AI tools to enhance our learning experiences, by looking at some (recent) research that has been done on the matter.
But as we embrace these new technologies, we must also ask ourselves:
Are we becoming less capable of thinking for ourselves?
Do these tools make us smarter, or do they risk dulling our critical thinking skills?
This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.Meet You in the Middle: 1000x Performance for Parquet Queries on PB-Scale Dat...

Speaker:
David Zhu (Engineering Manager @ Alluxio)
Storing data as Parquet files on cloud object storage, such as AWS S3, has become prevalent not only for large-scale data lakes but also as lightweight feature stores for training and inference, or as document stores for Retrieval-Augmented Generation (RAG). However, querying petabyte-to-exabyte-scale data lakes directly from S3 remains notoriously slow, with latencies typically ranging from hundreds of milliseconds to several seconds.
In this webinar, David Zhu, Software Engineering Manager at Alluxio, will present the results of a joint collaboration between Alluxio and a leading SaaS and data infrastructure enterprise that explored leveraging Alluxio as a high-performance caching and acceleration layer atop AWS S3 for ultra-fast querying of Parquet files at PB scale.
David will share:
- How Alluxio delivers sub-millisecond Time-to-First-Byte (TTFB) for Parquet queries, comparable to S3 Express One Zone, without requiring specialized hardware, data format changes, or data migration from your existing data lake.
- The architecture that enables Alluxios throughput to scale linearly with cluster size, achieving one million queries per second on a modest 50-node deployment, surpassing S3 Express single-account throughput by 50x without latency degradation.
- Specifics on how Alluxio offloads partial Parquet read operations and reduces overhead, enabling direct, ultra-low-latency point queries in hundreds of microseconds and achieving a 1,000x performance gain over traditional S3 querying methods.On-Device AI: Is It Time to Go All-In, or Do We Still Need the Cloud?

Efficient data migration is a critical challenge in geospatial data management, especially when working with complex data structures. This presentation explores an automated approach to migrating ESRI Geodatabases using FME and XML-based control files. A key advantage of this method is its adaptability: changes to the data model are seamlessly incorporated into the migration process without requiring modifications to the underlying FME workflow. By separating data model definitions from migration logic, this approach ensures flexibility, reduces maintenance effort, and enhances scalability.Async-ronizing Success at Wix - Patterns for Seamless Microservices - Devoxx ...

In a world where speed, resilience, and fault tolerance define success, Wix leverages Kafka to power asynchronous programming across 4,000 microservices. This talk explores four key patterns that boost developer velocity while solving common challenges with scalable, efficient, and reliable solutions:
1. Integration Events: Shift from synchronous calls to pre-fetching to reduce query latency and improve user experience.
2. Task Queue: Offload non-critical tasks like notifications to streamline request flows.
3. Task Scheduler: Enable precise, fault-tolerant delayed or recurring workflows with robust scheduling.
4. Iterator for Long-running Jobs: Process extensive workloads via chunked execution, optimizing scalability and resilience.
For each pattern, well discuss benefits, challenges, and how we mitigate drawbacks to create practical solutions
This session offers actionable insights for developers and architects tackling distributed systems, helping refine microservices and adopting Kafka-driven async excellence.MOVIE RECOMMENDATION SYSTEM, UDUMULA GOPI REDDY, Y24MC13085.pptx

Will future languages be created by language engineers?
Can you "vibe" a DSL?
In this talk, we will explore the changing landscape of language engineering and discuss how Artificial Intelligence and low-code/no-code techniques can play a role in this future by helping in the definition, use, execution, and testing of new languages. Even empowering non-tech users to create their own language infrastructure. Maybe without them even realizing. GDG Douglas - Google AI Agents: Your Next Intern?
