Virtual reality immerses users in a simulated, interactive world. Key technologies include display systems, tracking systems, and virtual world construction. Display systems must provide an immersive experience and block out the real world. Head-mounted displays and CAVE environments are common display methods. Tracking systems monitor users' body position and motion. Augmented reality enhances the real world with virtual objects, while mixed reality merges real and virtual worlds for new interactive environments. Virtual reality applications include therapy for PTSD patients by gradually exposing them to past trauma.

This document summarizes a project to control a virtual human using gestures recognized by the Microsoft Kinect sensor. The Kinect tracks users' joint positions and gestures are recognized by comparing relative joint locations. Gestures like moving the hands up and down control the virtual human's heart rate and blood pressure. Performing CPR is recognized by moving the hands in and out towards the torso. The virtual human then displays appropriate animations and reactions based on its physiological state.

This document discusses the history of hermeneutical thinking and responses to obstacles in understanding. It begins with allegorical interpretation of myths in Hellenism and traces the development of hermeneutics through contemporary views that the hermeneutical problem is universal. The document presents an overview of contemporary hermeneutical schools of thought and their roots in the hermeneutical tradition. While focused on biblical interpretation, it also considers developments outside of theology that influence theological reflection on hermeneutics.

Main news related to the CCS TSI 2023 (2023/1695)
An English 🇬🇧 translation of a presentation to the speech I gave about the main changes brought by CCS TSI 2023 at the biggest Czech conference on Communications and signalling systems on Railways, which was held in Clarion Hotel Olomouc from 7th to 9th November 2023 (konferenceszt.cz). Attended by around 500 participants and 200 on-line followers.

5th LF Energy Power Grid Model Meet-up Slides
5th Power Grid Model Meet-up
It is with great pleasure that we extend to you an invitation to the 5th Power Grid Model Meet-up, scheduled for 6th June 2024. This event will adopt a hybrid format, allowing participants to join us either through an online Mircosoft Teams session or in person at TU/e located at Den Dolech 2, Eindhoven, Netherlands. The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
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.

"Frontline Battles with DDoS: Best practices and Lessons Learned", Igor Ivaniuk
At this talk we will discuss DDoS protection tools and best practices, discuss network architectures and what AWS has to offer. Also, we will look into one of the largest DDoS attacks on Ukrainian infrastructure that happened in February 2022. We'll see, what techniques helped to keep the web resources available for Ukrainians and how AWS improved DDoS protection for all customers based on Ukraine experience
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.

Editor's Notes
- A good novel is immersive without any fancy graphics or audio hardware. You 'see' and 'hear' and 'touch' and 'taste' and 'smell' A good play or a film or an opera can be immersive using only sight and sound. But they aren't interactive which is another key element. Another key element of VR is a viewer centered perspective where you 'see' through your own eyes as you move through a computer generated space, interact with objects there, and more often than not kill everyone you meet. The way you see the environment is limited to a screen with a narrow angle of view and you use a keyboard / joystick / gamepad to change your view of that scene.
- the visual (and aural and haptic) displays that immerse the user in the virtual world and that block out contradictory sensory impressions from the real world; the graphics rendering system that generates, at 20 to 30 frames per second, the ever-changing images; the tracking system that continually reports the position and orientation of the user’s head and limbs; and the database construction and maintenance system for building and maintaining detailed and realistic models of the virtual world.
- The walls of the CAVE are made up of rear-projection screens, and the floor is made of a down-projection screen. High-resolution projectors display images on each of the screens by projecting the images onto mirrors which reflect the images onto the projection screens. The user will go inside of the CAVE wearing special glasses to allow for the 3-D graphics that are generated by the CAVE to be seen. With these glasses, people using the CAVE can actually see objects floating in the air, and can walk around them, getting a proper view of what the object would look like when they walk around it. This is made possible with electromagnetic sensors.
