M3O: The Multimedia Metadata Ontology
•
1 like•881 views
M3O is a multimedia metadata ontology that provides a formal framework for annotating multimedia content like presentations. It separates information objects from their realizations in different formats. M3O models information objects, their realizations, and annotations. It can be used to semantically annotate multimedia documents like SMIL presentations by embedding RDF metadata that describes the information and structure using concepts from M3O.

HPC Midlands - Cloud Supercomputing for Academia and Industry
These are my slides for the IDC HPC User Forum meeting at Imperial College in July 2012, introducing HPC Midlands. HPC Midlands is a cloud supercomputing service for academic and industrial use, supported by a £1m grant from the EPSRC.
DATE 2018
The LEGaTO project received funding from the European Union to develop a low energy software stack optimized for heterogeneous computing on European CPUs, GPUs, FPGAs and dataflow engines, with the goals of supporting energy efficient and task-based programming for smart home/city, AI and health use cases. The project involves 11 European partners including universities, research centers and companies.

This document discusses cloud computing and the European Commission's strategy around it. It defines cloud computing and outlines some of the key challenges. It then summarizes the European Union's Digital Agenda, which calls for an EU-wide cloud computing strategy. Public consultations were conducted and a strategy is planned for 2012. Public administrations are reluctant to use public clouds due to security and privacy concerns but see cost reduction benefits. The document provides some relevant links for additional information.
Unlocking the Semantics of Multimedia Presentations in the Web with the Multi...
The semantics of rich multimedia presentations in the web such as SMIL, SVG, and Flash cannot or only to a very limited extend be understood by search engines today.
This hampers the retrieval of such presentations and makes their archival and management a difficult task.
Existing metadata models and metadata standards are either conceptually too narrow, focus on a specific media type only, cannot be used and combined together, or are not practically applicable for the semantic description of rich multimedia presentations.
In this paper, we propose the Multimedia Metadata Ontology (M3O) for annotating rich, structured multimedia presentations.
The M3O provides a generic modeling framework for representing sophisticated multimedia metadata.
It allows for integrating the features provided by the existing metadata models and metadata standards.
Our approach bases on Semantic Web technologies and can be easily integrated with multimedia formats such as the W3C standards SMIL and SVG.
With the M3O, we unlock the semantics of rich multimedia presentations in the web by making the semantics machine-readable and machine-understandable.
The M3O is used with our SemanticMM4U framework for the multi-channel generation of semantically-rich multimedia presentations.
Sweo talk
The document introduces the Semantic Web and its goals of making web content machine-readable through the use of ontologies and semantic annotations. It describes the evolution of the web from human-readable documents and links to machine-processable data through technologies like XML, RDF, and OWL. It outlines current work by the W3C to develop standards and an active working group to develop the Semantic Web.
Implementing the Genetic Algorithm in XSLT: PoC
The document discusses using a genetic algorithm to automatically compose SOA applications by evolving XSLT programs. It describes setting up an initial population of random XSLT documents, transforming source XML with each XSLT to get result XML, comparing result XML to target XML via XML diff to calculate fitness, selecting individuals for reproduction and crossover to create new offspring, and repeating over generations to evolve higher fitness XSLT programs. The goal is to evolve an XSLT that can transform source XML into target XML.

Information Engineering in the Age of the Internet of Things
The document discusses information engineering challenges in the age of the Internet of Things (IoT). It notes that while semantic models and ontologies are useful, simplicity is important for real-world implementation. Dynamic and streaming IoT data also requires approaches different from traditional semantic web techniques. The document provides several "design commandments" focused on usability, interoperability, and accounting for the constraints of IoT environments. Overall, it argues that semantics are just one part of effectively handling and processing IoT data.

He then explains how standards like OPC UA are important for connecting diverse industrial devices and systems in an interoperable way.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
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.

HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away

Introduction of Cybersecurity with OSS at Code Europe 2024
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.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
