In the beginning itself, the blockchain was mostly heard for its possible applications in the financial domain. Bitcoin started it, and now most of the existing financial infrastructures are attracted towards the blockchain technology. Many of the financial institutions already started to implement blockchain assisted technologies. Consequently, more finance domain specific blockchain development platforms also came into existence. Corda is one of them

2021’s hottest new tech term, according to TechCrunch, was “definitely Web3”. Web3, as its name suggests, is considered by many as the future of the internet: decentralized, permissionless, and based on modern blockchain technology. While Web3 might have a bright future, it’s in the middle of growing pains: A number of Web3 apps were hacked in 2021, leading to theft of cryptoassets valued at hundreds of millions of US Dollars. In this talk we will present Web3 app technology, dissect new attack surfaces, and suggest new and exciting defense mechanisms. First, we will dive into the technical details of Web3 applications, showing how Web3 technology opens new attack surfaces by moving app functionality onto the blockchain. We will then analyze these newly-exposed attack surfaces by reviewing a few examples we’ve discovered “in the wild.” While Web3 exposes new attack surfaces, it also provides novel detection opportunities. Specifically, the public and transparent nature of the blockchain allows security researchers to immediately explore full details of any attack and, as a result, leads to quick and thorough discoveries. This is a paradigm shift in security research, as current practices only allow a few to learn actual attack details, only some portions of which are shared publicly. This shift in transparency allowed us to independently explore the aforementioned attacks. Furthermore, we believe we can do even better and go beyond rapid post-mortem reports. We will show how the same raw data we had previously used for a post-mortem analysis can be analyzed in real-time (or even ante factum by “taking a peek” into the blocks that have yet to be mined) to detect and even prevent attacks. This capability is enabled by the online nature of the blockchain and its inherent block time delays. In fact, we can import, with relevant modifications, many of the principles and learnings of current web defenses, including Web Application Firewall (WAF) into the realm of blockchain. By doing so, we introduce a scheme for a Web3 Application Firewall (W3AF) which can greatly improve Web3 security and blockchain-based apps.

The Harvard Business Review (HBR) thinks that Blockchain Technology has to power to keep data safe for consumers and businesses alike; because Blockchain provides a secure and immutable ledger, HBR says it represents the key to taking back privacy of data. “You can keep certified copies of identity documents, biometric test results, health data, or academic and training certificates online, available at all times, yet safe unless you give away your key. At a whole system level, the database is very secure.”

The blockchain concept may be one of the most transformative ideas to impact the world since the Internet. Cryptocurrencies like bitcoin are merely one application of the blockchain concept. The blockchain is a public transaction ledger built in a decentralized network structure based on cryptographic principles so that any kind of trading, buying and selling of assets does not need to go through a centralized intermediary. Any kind of asset may be encoded into the blockchain and transacted, validated, or preserved in a much more efficient manner than at present including ideas, health data, financial assets, automobiles, and government documents. Venture Capitalists are calling the blockchain the next big investment wave.

Blockchain is a revolutionary technology that is changing the way we handle digital transactions. It is a technology that can be applied in many different fields, from logistics and supply chain management to real estate and voting systems. In order to help our clients to plan and execute digital transformation, we need to understand foundational elements, including smart contracts and languages that are popular in developing smart contracts. In this presentation, we share an overview of what a smart contract is and how it functions, look into the real-world examples of smart contracts, and tools that are used to develop smart contracts. We look into Solidity, a powerful programming language that enables developers to create complex and sophisticated smart contract applications on Ethereum-compatible blockchains. There is no expectation of prior knowledge of blockchain technology or smart contracts development and we are expecting to have a lively and engaging session.

This slides show a more complex rollout real world scenario in combination of usb-based crypto keys used in parallel under linux and windows and cross-browser on windows too! Good thing is - no passwords must be stored on any of the authentication systems - no passwords can be stolen! ;-) Slides just give an overview over the overall architecture but was really working - see pictures on last slides - where the same certificate from the usb key is shown under linux and windows - still neat. Somehow not much seems to have changed since 2004 if one looks around - could still be applied in todays environments - the basics and it's still not wide spread nowadays. Note: Slides are historical versions from 2004, so not all shown hardware, protocols and/or drivers/software may be available or recommended for usage anymore. Today I would prefere OpenXPKI which forked of OpenCA and is an fully independent version by now close to 1.0 release this or next year! Check it out!

In the realm of real-time applications, Large Language Models (LLMs) have long dominated language-centric tasks, while tools like OpenCV have excelled in the visual domain. However, the future (maybe) lies in the fusion of LLMs and deep learning, giving birth to the revolutionary concept of Large Action Models (LAMs). Imagine a world where AI not only comprehends language but mimics human actions on technology interfaces. For example, the Rabbit r1 device presented at CES 2024, driven by an AI operating system and LAM, brings this vision to life. It executes complex commands, leveraging GUIs with unprecedented ease. In this presentation, join me on a journey as a software engineer tinkering with WebRTC, Janus, and LLM/LAMs. Together, we’ll evaluate the current state of these AI technologies, unraveling the potential they hold for shaping the future of real-time applications.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
