Markets of all types, whether stocks, bets or street vendors, bring people together to exchange goods and services. Through prices that transmit information, markets allow people to summarize information, trigger conversations, and get a true sense of any situation in a useful way. All markets essentially operate in the same manner by facilitating interactions that disseminate knowledge.
Online Education and Virtual OrganizationsSteve McCarty
The document discusses online education and virtual organizations. It proposes defining terms in these fields multidimensionally by including their cultural, disciplinary, and temporal contexts. Virtual organizations can take various forms, such as non-profit organizations, interest groups, or academic societies. They may be local, regional, or global in scope. The World Association for Online Education is provided as an example of a virtual organization that connects educators through online venues and courses. Web 2.0 technologies allow access to people and information through social networking services but require understanding from multiple perspectives, including how organizations use these technologies.
Wadja.com is a social messaging and mobile media website that has grown rapidly since its beta launch in 2006. It has over 750,000 registered users from more than 180 countries.

Some simple and straightforward steps on how to be innovative - out of my humble experiences so far
This document discusses the growth of Greek web startups over time. It notes that Greek web startups were once thought to not exist, be unable to succeed, have no interest, and have obscure potential, but that views have changed - they now exist, are able to succeed, have huge interest, and even bigger potential. It acknowledges how far Greek web startups have come but that more potential still lies ahead.
This document introduces askmarkets, a platform that allows users to create their own prediction markets to aggregate information and forecast outcomes. It argues that traditional tools like surveys and meetings are inefficient at tapping into collective intelligence. Prediction markets bring people together, facilitate discussions, synthesize information, and transmit it through prices. The document shows screenshots of Yahoo stock prices on Google Finance to illustrate how news gets incorporated into prices. It then explains that askmarkets allows users to create their own questions, enter predictions, and see collective forecasts form. Users can also create private or public marketplaces for their organizations. The document promotes askmarkets as a wise decision-making tool that is especially useful during tough times.
Based on a telephone survey of 500 households, 57% of the target market thinks a new product will be successful. After a 2 hour meeting, executives agree to move forward with developing a product idea called XYZ. The general sales manager estimates they will sell 5.2 million pieces of the product in 2009.

Sync.gr run an extensive survey on greek blogosphere. Here you may find an extended data mining analysis on the results, provided by http://DataMine.it
This document discusses using prediction markets to aggregate information and forecast events. It notes that traditional markets transmit information through stock prices as news is incorporated. Similarly, prediction markets can be used to forecast things like company sales, project deadlines, or a competitor's market share. The document promotes a website, AskMarkets.com, that allows users to create their own prediction markets to estimate probabilities of future events that matter for their organization or enterprise. Creating and participating in markets on the site is described as a simple process.
A DataMine.it Case Study: Analyzing EarthquakesGeorge Tziralis
The document is a data analysis report prepared by Eirini Lygkoni for George Stamatopoulos that summarizes the results of extensive data mining performed on a seismology data set. The analysis revealed several important rules and patterns relating attributes like earthquake depth, epicenter location, and year to magnitude. Key findings included that earthquakes before 1964 with depths less than 10 km tended to have magnitudes over 6.5, and quakes with epicenters over 38.26 km and depths over 19 km also tended to be over magnitude 6.5.
Quantitative Model For an Impact Measurement SystemGeorge Tziralis
1. The document presents a quantitative model for measuring the impact of factors like tourism on a system using multiple steps.
2. It involves identifying impact factors, structuring them hierarchically, quantifying the effect of each factor using analytic hierarchy process to prioritize them.
3. The most influential factors are then further analyzed using techniques like Paasche's index, Laspeyres' index, and decomposition analysis to quantify their impact over time.
The document discusses a new tool called "Social Impact" that quantifies a person's influence across social networks. It was created by a team that spent a weekend building crawlers to scan social networks, store valuable information, and develop an algorithm to provide a single metric of social impact. The tool offers three services - free individual reports of social impact, standard reports on influential people in certain groups/topics, and premium on-demand reports for customer-provided lists. The goal is to identify the most informationally effective people for spreading messages.

This document discusses graphs and graph representation. It begins by introducing some basic graph terminology like directed and undirected graphs, paths, cycles, trees, and connected components. It then discusses various ways to represent graphs including adjacency lists, adjacency arrays, adjacency matrices, and implicit representations. It provides examples of graph operations and algorithms like recognizing directed acyclic graphs and checking connectivity of interval graphs.
Market Drive Innovation Management, from the inside inGeorge Tziralis
This document discusses using internal markets as a tool for innovation management and idea selection. It notes that traditional evaluation methods are often inefficient and lack motivation. The authors propose allowing employees to trade virtual currency to "buy" and "sell" ideas, with the market prices aggregating information to indicate the most promising concepts. The internal market approach could perform idea selection as a distributed computation, leveraging the power of markets to bring people together, trigger conversations, and efficiently summarize information.

From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
LF Energy Webinar: Carbon Data Specifications: Mechanisms to Improve Data Acc...DanBrown980551
This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
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.

- Share actionable ways you can participate in Knowledge - - Capture & Transfer
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.
"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
