This document discusses techniques for image coding and compression, including predicting pixel values from neighboring pixels, encoding differences between actual and predicted values (DPCM), and adapting the mapping of bits to differences over time (ADPCM). DPCM removes redundancy by transmitting only differences between samples, which are normally small. ADPCM varies this mapping dynamically so more bits can be used for rapid changes and fewer for slow changes. Overall the document focuses on prediction-based approaches to reduce image data by exploiting spatial and temporal correlations between pixels.

Wavelength converters are devices that convert data from one incoming wavelength to another wavelength. They enable optical channels to be relocated and are achieved using nonlinear optical effects. Wavelength converters are useful in WDM networks for three reasons: 1) data may enter the network at an unsuitable wavelength, 2) converters may improve wavelength utilization on network links, and 3) converters may be needed when networks managed by different entities do not coordinate wavelength allocation. Common types of wavelength converters include optoelectronic, optical gating using cross-gain modulation, and four-wave mixing approaches.

zOS CommServer support for the Network Express feature on z17zOSCommserver
?
The IBM z17 has undergone a transformation with an entirely new System I/O hardware and architecture model for both storage and networking. The z17 offers I/O capability that is integrated directly within the Z processor complex. The new system design moves I/O operations closer to the system processor and memory. This new design approach transforms I/O operations allowing Z workloads to grow and scale to meet the growing needs of current and future IBM Hybrid Cloud Enterprise workloads. This presentation will focus on the networking I/O transformation by introducing you to the new IBM z17 Network Express feature.
The Network Express feature introduces new system architecture called Enhanced QDIO (EQDIO). EQDIO allows the updated z/OS Communications Server software to interact with the Network Express hardware using new optimized I/O operations. The new design and optimizations are required to meet the demand of the continuously growing I/O rates. Network Express and EQDIO build the foundation for the introduction of advanced Ethernet and networking capabilities for the future of IBM Z Hybrid Cloud Enterprise users.
The Network Express feature also combines the functionality of both the OSA-Express and RoCE Express features into a single feature or adapter. A single Network Express port supports both IP protocols and RDMA protocols. This allows each Network Express port to function as both a standard NIC for Ethernet and as an RDMA capable NIC (RNIC) for RoCE protocols. Converging both protocols to a single adapter reduces Z customers¡¯ cost for physical networking resources. With this change, IBM Z customers can now exploit Shared Memory Communications (SMC) leveraging RDMA (SMC-R) technology without incurring additional hardware costs.
In this session, the speakers will focus on how z/OS Communications Server has been updated to support the Network Express feature. An introduction to the new Enhanced QDIO Ethernet (EQENET) interface statement used to configure the new OSA is provided. EQDIO provides a variety of simplifications, such as no longer requiring VTAM user defined TRLEs, uses smarter defaults and removes outdated parameters. The speakers will also cover migration considerations for Network Express. In addition, the operational aspects of managing and monitoring the new OSA and RoCE interfaces will be covered. The speakers will also take you through the enhancements made to optimize both inbound and outbound network traffic. Come join us, step aboard and learn how z/OS Communications Server is bringing you the future in network communications with the IBM z17 Network Express feature.

AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATIONmiso_uam
?
AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATION (plenary talk at ANNSIM'2025)
Testing is essential to improve the correctness of software systems. Metamorphic testing (MT) is an approach especially suited when the system under test lacks oracles, or they are expensive to compute. However, building an MT environment for a particular domain (e.g., cloud simulation, automated driving simulation, production system simulation, etc) requires substantial effort.
To alleviate this problem, we propose a model-driven engineering approach to automate the construction of MT environments, which is especially useful to test domain-specific modelling and simulation systems. Starting from a meta-model capturing the domain concepts, and a description of the domain execution environment, our approach produces an MT environment featuring comprehensive support for the MT process. This includes the definition of domain-specific metamorphic relations, their evaluation, detailed reporting of the testing results, and the automated search-based generation of follow-up test cases.
In this talk, I presented the approach, along with ongoing work and perspectives for integrating intelligence assistance based on large language models in the MT process. The work is a joint collaboration with Pablo G¨®mez-Abajo, Pablo C. Ca?izares and Esther Guerra from the miso research group and Alberto N¨²?ez from UCM.

How John started to like TDD (instead of hating it) (ViennaJUG, June'25)Nacho Cougil
?
Let me share a story about how John (a developer like any other) started to understand (and enjoy) writing Tests before the Production code.
We've all felt an inevitable "tedium" when writing tests, haven't we? If it's boring, if it's complicated or unnecessary? Isn't it? John thought so too, and, as much as he had heard about writing tests before production code, he had never managed to put it into practice, and even when he had tried, John had become even more frustrated at not understanding how to put it into practice outside of a few examples katas ??¡á?
Listen to this story in which I will explain how John went from not understanding Test Driven Development (TDD) to being passionate about it... so much that now he doesn't want to work any other way ? ! He must have found some benefits in practising it, right? He says he has more advantages than working in any other way (e.g., you'll find defects earlier, you'll have a faster feedback loop or your code will be easier to refactor), but I'd better explain it to you in the session, right?
PS: Think of John as a random person, as if he was even the speaker of this talk ? !
