To make sure everyone finds each other smoothly, please follow these simple coordination steps: 1️⃣ **RSVP** Thoughtfully If you’re planning to come, tap “Going.” It helps others feel confident joining and builds momentum before the meetup. Even if you’re 80% sure, RSVP. If your plans change, please update your RSVP so others aren’t expecting your attendance. 2️⃣ **Confirm 2 Hours Before** (Essential) To ensure the meetup runs, please comment on this event page at least 2 hours before the start time: “Confirmed for today 😊” This allows everyone to see, ahead of time, who is actually coming. The meetup moves forward when at least 2 people confirm 2 hours before the event. If fewer than 2 confirmations are posted by then, attendance may be low that day. This avoids anyone showing up uncertain. 3️⃣ **Signal Your Arrival** When you arrive, comment on this event page: “Arrived” + where you’re sitting + what you’re wearing Example: “Arrived. Sitting outside near the entrance. Wearing a black t-shirt.” This ensures everyone can easily find each other.

​​**Let's discuss a ted talk video while taking a walk at Capital Crescent Trail Near Bethesda.** **To receive future event updates, register on Luma:** [https://luma.com/tv3fhasq](https://luma.com/tv3fhasq) Have you had your daily dose of fun? It's not just enjoyable, it's also essential for your health and happiness, says science journalist Catherine Price. She proposes a new definition of fun -- what she calls "true fun" -- and shares easy, evidence-backed ways to weave playfulness, flow and connection into your everyday life. ​​​​Here is how it works: * ​​​​​​​Prior to the event: **Please watch this YouTube video:** [https://www.youtube.com/watch?v=iMBJrvEwv8s](https://www.youtube.com/watch?v=iMBJrvEwv8s) * ​During the event: * ​​3:30pm-3:45pm: meet outside of [Chopt Salad](https://maps.app.goo.gl/ThxMNixG2TG4T32X6) (Bethesda Row end of Capital Crescent Trail) for group introduction. * ​3:45pm-4:45pm: Take a walk at Capital Crescent Trail (laps between Bethesda Row and Little Falls Parkway) and Discuss. * ​(Walking Route Link: [https://scenic-walk.com/#/b712c5fa ](https://scenic-walk.com/#/b712c5fa)(During the hike, the organizer will live broadcast current location, so that people who arrive late can catch up via the [Scenic Walk Link](https://scenic-walk.com/#/b712c5fa)). * ​4:45pm - 5pm: Group Conclusion outside of Chopt Salad. *** ​​​​Discussion Questions During Walk: \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1. **True fun is a visceral feeling of being illuminated from within rather than just a leisure activity. How can we better distinguish between activities that merely pass the time and those that truly make us feel radiant?** 2. **Playfulness involves a lighthearted attitude of doing things for their own sake without worrying about the outcome. How might our community change if we collectively lowered our guards and let go of the need for perfection?** 3. **Most peak fun memories involve a shared experience that helps us feel united with others. In a polarized world, how can the pursuit of fun serve as a bridge to connect us as human beings?** 4. **Fun requires a state of flow where we are so engaged that we lose track of time. What environments can we create together that naturally encourage us to be fully present and focused on the moment?** 5. **Prioritizing fun acts as a legitimate health intervention by reducing stress and promoting social bonding. How would we shift our schedules if we viewed joyful moments as essential to our physical and mental well-being?** 6. **Constant digital distractions interrupt our flow and prevent us from forming real-world connections. What boundaries can we set with our devices to ensure we remain available for spontaneous moments of joy?** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- To provide an enjoyable experience for fellow participants, here are three ground rules during discussion events: 1. Step up and step back. (If you feel that you’ve been talking too much, step back to listen more. If you feel that you’ve been relatively quiet, step up to share your perspective or ask a question) 2. Listen to understand, not to respond. 3. Be open-minded and value differences.

Similar to our "Beginner Ride", a casual, on-road-avoiding, cycle-path-winding, beginner friendly, group ride. The ride will be led by Maya and Angie, who have a combined 50 years of cycling experience. This is a no drop ride with an average speed of 7- 12 mph. Please bring a helmet, lights, a snack, hydration and wear appropriate clothing for cooler weather (cotton is not your friend in cooler temps and we will be riding in the dark). The ride can be tailored to the skills that attendees want to master, i.e- drinking from water bottle while riding, making tight turns, riding in a small group and cycling etiquette. We will be riding mainly on trails, streets as minimally as possible, and sidewalks only when necessary. This ride is perfect for someone who hasn't ridden in a while and wants to get some easy miles on the saddle; not just for newbies. If you have not ridden your bike in several weeks, months or years, please have a safety check done before the day of the ride. We are just here to have fun.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .] Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go. Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less. Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you. She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level. Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using. You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency. Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior. We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less. You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress.

**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.
