This document provides instructions for a basic bouncing ball animation exercise. It describes the key principles of animation that students will learn by completing this exercise, including: depicting the ball's movement in an arc rather than a straight line; adjusting the timing and spacing of frames to show acceleration and deceleration; using squash and stretch to show the ball compressing and expanding during its bounce; and maintaining a consistent volume while the ball deforms. Students are guided to draw key frames at specific points in the bounce and fill in intermediate frames to smooth the animation.

Containers & AI - Beauty and the Beast!?!
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Apps Break Data
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?

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.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Bouncing Ball Exercise
- 1. Animation Bouncing Ball Exercise Thursday, 19 November 2009
- 2. The Bouncing Ball Tutorial This is the first lesson taught to any animation student. By following it you will grasp most of the principals used in animation. Thursday, 19 November 2009
- 3. Thursday, 19 November 2009
- 4. Here are all the frames of the animation sequence Thursday, 19 November 2009
- 5. 1. The Arc The ball falls in an elliptical arc through space. Most things move in an arc of some kind. N.B. If the ball were to move in a straight line between the high and low points of the bounce, then the action would look very unnatural. Thursday, 19 November 2009
- 6. 2a. Timing (or Spacing)- DOWN As the ball falls it is accelerated by gravity, the gap between each frame growing all the time until the ball contacts the ground. Thursday, 19 November 2009
- 7. 2b. Timing (or Spacing)- UP As the ball bounces from the ground the opposite happens: as the ball hops up it moves very fast at first, then slows down by gravity into the high point of its bounce. Thursday, 19 November 2009
- 8. 2c. Timing (or Spacing) Mark the position of each ball on the arc path with an X and then number them Thursday, 19 November 2009
- 9. 3. Squash and Stretch As the ball falls it stretches. When it impacts the ground it squashes. When it bounces off the ground it stretches again. Note how quickly the ball regains its circular shape. Too much squash and stretch can make an object look “mushy” Thursday, 19 November 2009
- 10. 4. Volume The ball should remain the same mass as it squashes and stretches. If the ball were to squash too much it would seem to be growing physically bigger. This is very eye catching, and looks weird. Thursday, 19 November 2009
- 11. 5. Key Frames On separate sheets, draw the different key frames. If done correctly you should have a series of drawing numbered 1,7,12,17,21,25,28 and 31. Write the frame numbers on each drawing. Key frames have a circle around them. Thursday, 19 November 2009
- 12. 6. Inbetween Frames Now you must add the inbetween frames. These are the drawings that go between the keys in order to make the action look smooth. Thursday, 19 November 2009
