The document then discusses criticisms of ESBs, such as lack of standardization, vendor lock-in, and focus on specific technologies. It introduces CXF as an open source ESB framework that aims to address these issues and provides examples of using CXF for exposing, consuming and testing web services in a flexible way. In the end it concludes that while ESBs can be useful in complex scenarios, alternatives should also
The document compares REST and SOAP architectures for distributed computing. It defines REST as a web services style based on HTTP that designs operations on data, while SOAP is a protocol for exchanging structured information that offers application logic as a service. The document then outlines key differences, with REST being more lightweight, flexible and oriented towards data, while SOAP focuses more on operations, security and reliability. It concludes by recommending REST unless specific needs require SOAP.
In this presentation, Marc Dutoo, R&D Lead at Open Wide, shows why and how the EasySOA project's architecture integrates OW2 components, notably FraSCAti and Nuxeo.

This document provides an overview of key concepts in Service Oriented Architecture (SOA) including building blocks like XML, web services, and SOAP. It also describes concepts like the Service Component Architecture (SCA) and components of the Oracle SOA Suite 11g like the mediator component. Additional sections cover topics like deploying composite applications, creating adapter services, developing BPEL processes, and integrating with the Oracle BAM for business activity monitoring.
The document discusses network architecture and proposes improvements to current approaches. It suggests treating layers as units that provide interprocess communication over different scopes. Each layer would provide a single type of service and the number of layers is not fixed. It also proposes having a single unified data transfer protocol framework and layer management protocol across all layers to reduce complexity. This would help standardization bodies design complete network protocols more easily.

Oracle SOA Suite 11g Mediator vs. Oracle Service Bus (OSB)Guido Schmutz
With Oracle SOA Suite 11g the old Oracle ESB become the Mediator component. With that only one "real" service bus resides, the Oracle Serivce Bus (OSB), which has been taken over from BEA (used to be Aqualogic Service Bus).
Mediator and OSB have some overlapping funcitonality, like transformation, routing and filtering. The question automatically raised is of course when to use which component. This presentation shows the difference between the components, the functionality they provide and some typical use cases for both.
This document summarizes key concepts related to web services technologies including service-oriented architecture (SOA), XML, SOAP, WSDL, and UDDI. It discusses how these standards enable application integration and interoperability. The rise of web services allows for a more flexible and agile approach to developing applications and integrating systems. Major benefits include loose coupling, reusability, and simplifying enterprise application integration. However, web services also face challenges related to performance and managing expectations.
The document discusses the OSI reference model, which was created by the ISO to standardize network technologies and ensure interoperability. The seven-layer OSI model reduces complexity, standardizes interfaces between layers, and facilitates modular engineering.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.
In the realm of cybersecurity, offensive security practices act as a critical shield.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

middleware is to connect the different services
involved independent[ly] of their location (local
