Observability is supposed to help us understand our systems but for many teams it has quietly become one of the most expensive and least flexible parts of the stack. Plenty of organizations take polished SaaS platforms like Datadog to get real value quickly early on, only to hit the same wall later: runaway costs, pricing tied to architectural decisions, and vendor lock-in so strong it makes Rogers and Bell both blush. In this talk, I’ll walk through a real-world case study of a JVM-based production system that migrated away from a Datadog-centric observability setup to an open-source, OpenTelemetry-based platform. We’ll dig into the why behind the move, the architectural decisions that mattered, the mistakes along the way, and how the team ended up with pragmatic visibility into latency, errors, and resource usage at a fraction of the cost. The second half of the talk is practical and forward-looking. I’ll show how OpenTelemetry unlocks real choice by acting as a neutral data plane for your telemetry. From there, we’ll look at modern, off-the-shelf observability backends you can plug in within minutes without rewriting applications or installing new agents. Want to dual-write, swap vendors, or route data somewhere new? This is how you do it without a big-bang rewrite or another long-term commitment with a new vendor. This session is for engineers and CEOs who are feeling the observability cost squeeze, want leverage back from vendors, and are looking for realistic ways to modernize monitoring without lighting their entire stack on fire each time they decide to change their tools of choice. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk. **Speaker Bio** Alexei Zenin is a Platform Engineering Consultant based out of Toronto, Canada. Over the course of his career he has worked across the Healthcare, Marketing, Video Games, and Banking industries.

During his 5 years at Uken Games he contributed to several games like Who Wants to Be a Millionaire and Jeopardy. One title of note he saw from inception to completion was a game for Tim Hortons built right into the official app, Tim’s Word Challenge. Millions of Canadians have played it along with their morning coffee. He also got to work with Netflix on several unannounced games during his time at the studio. Currently, Alexei is working with various clients, both large and small to modernize and streamline their platforms with the most appropriate tools and practices. Outside of his professional life, he gives back to his community by volunteering at UofT. He also enjoys paddleboarding and attending live rock concerts to reset after long coding sessions.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/yvAGbh4PpD **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.

**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
