In modern Java applications, distributed systems are everywhere, and so are failure modes. But how do you know when your cluster is fragile, or if it’s on the brink of breaking? This talk dives into practical observability and resiliency techniques for distributed Java environments. We’ll highlight key patterns, failure signals, and metrics that matter, backed by a live demo using Hazelcast, Chaos-mesh, Prometheus, and Grafana. You’ll learn: Core Patterns – Leader election, partitioning, replication Metrics That Matter – Backup count, member count, JVM health, Golden Signals Failure-Aware Design – Resilience patterns, chaos testing principles Live Demo – Deploy a working cluster, simulate node failure, and explore metrics to observe how data integrity holds as the system nears its fault tolerance threshold Ideal for Java developers, architects, and SREs, this session blends theory, tools, and real-world failure scenarios to help you build distributed systems that stay online—even when things go wrong. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu.

The intention is to offer a soft space where voices can be heard without interruption, pressure, or expectation. What to expect: • A calm, intimate setting • Poetry, spoken word, or short readings • A listening-first, supportive environment • No pressure to share or perform There is a $5 deposit to hold your spot that will be returned when you show up!

Happy Holidays! The first Wednesday of January is 7th, and this is Orthodox Christmas. And i will be wishing everyone Merry Christmas in January, and i am sure many of you will be tired from all this socializing. That is why we are going to meet on February 4th. And we will continue discussing the Hot topic of our age an AI. We’ve spent the last few sessions learning how to *talk* to AI. We’ve mastered prompt engineering and "vibecoding" to build things faster. Now, it’s time for the next leap: **letting AI work for us while we sleep.** In this session, we are moving beyond simple chatbots to explore **Autonomous AI Agents.** Unlike standard tools that wait for you to type a command, Agents are designed to perceive a goal, plan a series of tasks, and execute them independently within your WordPress site. We will discuss **Generative vs. Agentic AI:** Understanding the shift from *"Write me a blog post"* to *"Monitor local Knoxville news and draft a weekly summary every Friday."* I am sure many of you have seen WordPress ads offering different Agentic tools like **Uncanny Automator**, **AI Engine**, or **n8n**. What do these tools do? How successful they are? And how implementable all these agents are for your current WordPress site? I will gather some info and make research. But please join us and bring your stories and experience on topic. See you!

Are you in chronic pain that never seems to resolve, no matter who you see? Are you in a therapy loop of get better, get worse? Are you only getting your symptoms resolved and not the cause. I get it! I have been there. I have taken continuing education classes in therapies that have given me longer lasting results since they are the whole person approach. These consultations are 30 minutes each with a 15 minute mini session of neurokinetic therapy and Rapid Neurofascial Re-set and 15 minutes of question/answer. These consults are only available on this day and time since this is not something I normally offer. This gives you the option of sampling these therapies before deciding if you want to commit to a new client package. The consults are $60 each plus sales tax, which comes to $64.80. All spots are pre pay by the day before the event, non cancellable, non refundable and non transferrable. This is because people say they are showing up to stuff without showing up. Once the spot in paid for in full, I will schedule you your spot. If you decide to schedule a new client package during your consult, that $60 you paid for your consult will be deducted from the regular price of the new client package. This offer is only available during the consult. You can learn more about me and these therapies by visiting my website. My website also contains my contact information: https://columbusmassage.abmp.com/

**Photography 102: A Deeper Dive Into Photography** **Are you ready to dig deeper into photography? Then this intermediate photography course is perfect for expanding your knowledge of photography!** This intermediate photography class builds upon the foundational knowledge acquired in the Photography 101 class. It focuses on empowering students to move beyond automatic camera modes and take greater creative control over their images. This course uses an engaging and practical hands-on approach to reinforcing these newer and more advanced photographic concepts. **Through hands-on exercises and insightful lessons, you will learn:** * **Master More Advanced Camera Settings** * **Aperture and F-stops:** Understanding how aperture controls depth of field and using it to create blurry backgrounds (shallow depth of field) for portraits or sharp focus throughout a landscape (deep depth of field). * **Shutter Speed:** Learning to utilize shutter speed to freeze fast action or intentionally blur motion for artistic effects. * **ISO:** Exploring ISO settings for optimal image quality in different lighting conditions, understanding the trade-off between sensitivity and potential image noise/grain. * **Exposure Modes:** Beyond "Auto", understanding and utilizing manual (M), aperture-priority (A or Av), shutter-priority (S or Tv), and program (P) modes for specific shooting scenarios. * **White Balance:** Learn how to effectively set white balance controls to represent colors in varying lighting conditions properly. * **Metering and Exposure Compensation:** Understanding how the camera measures light and how to use exposure compensation to fine-tune exposure for desired results. * **On-Camera Flash Basics:** Gaining a basic understanding of when and how to use the built-in flash or external flash units effectively. * **Advanced Concepts and Techniques** * **Composition Beyond the Basics:** Looking at some more advanced composition concepts and taking a deeper look at the Elements of Design, learning to use space more effectively, controlling the elements of the scene that are drawing attention, and mastering visual weight. * **Lighting Beyond Natural Light:** Introduction to artificial lighting, such as off-camera flash, reflectors, and softboxes, to control and shape light for different effects. * **Basic Image Editing:** An introduction to photo editing software like Adobe Lightroom and Photoshop, covering essential tools for adjusting brightness, contrast, color, and sharpness. * **Developing a Personal Style:** Exploring ways to refine a unique artistic voice and create a consistent photographic style. **This class provides the next step in the path to becoming a more proficient and artistic photographer, allowing for more advanced usage of the camera system.** **Prerequisites:** * A camera (film, DSLR, or mirrorless) that has manual controls is required. Hands-on exercises make having the camera in class highly beneficial. You will need at least one lens to evaluate the results of control exercises. * You may attend this class in one of two ways: 1. With a class voucher provided by your retail camera store 2. Purchasing a seat in the class
