(Or, help mentor other attendees if you're already a whiz) • Ask for a code review for a project you've been working on by yourself • Talk through a particular problem with someone who has solved it before • Just hang out and have some cool conversations!

About us: Respect The Tech is an organization focused on information technology education and innovation. Our mission is to innovate technology education through virtual labs and gamified training.

This is an opportunity for volunteers to support a professional mechanic as he guides customers working on their own bikes. If you know how to do some basic repairs, that's a plus, but even if you don't, you can greet customers and manage who gets helped next. Feel free to attend for only a portion of the time if you can't be there the whole three hours. Please note that this event is not usually an opportunity to learn about bicycle repair, since the mechanic tends to be very busy helping customers, especially during the warmer months. But it's a great way to contribute to Velocity, since almost all the funding for the volunteer program comes from the work done at the shops.

meet at Tysons Corner Mall Upper Level Food Court

Details Location: Crimson Whiskey Bar (Downstairs Bar, Not Rooftop) The purpose of Thinkers and Drinkers is to facilitate casual but meaningful and interesting conversations with other people in a face-to-face setting. The topics cover a wide variety of issues and are different for every meeting. While conversations may get heated at times, we ask that all members be respectful of each other and refrain from personal insults. Topic: Trust in Institutions Across much of the world, trust in major institutions, including government, media, corporations, courts, universities, and science, appears to be shifting. Surveys often show declining confidence in public institutions, while at the same time people continue to rely on them for stability, information, and coordination. Recent years have included disputed elections, misinformation concerns, public health crises, economic disruptions, and rapid technological change. These events have raised difficult questions about credibility, legitimacy, and accountability. Some argue that skepticism toward institutions is healthy in a democracy, encouraging transparency and reform. Others worry that widespread distrust can weaken social cohesion and make collective problem solving nearly impossible. Major surveys and studies on institutional trust include: • Pew Research Center, Public Trust in Government: https://www.pewresearch.org/politics/2024/04/30/public-trust-in-government-1958-2024/ • Edelman Trust Barometer (annual global survey): https://www.edelman.com/trust/trust-barometer • Gallup, Confidence in Institutions: https://news.gallup.com/poll/1597/confidence-institutions.aspx • World Values Survey, Trust indicators across countries: https://www.worldvaluessurvey.org Historically, periods of low institutional trust have sometimes preceded major reforms or political realignments, while in other cases they have contributed to instability or authoritarian backlash. Understanding when distrust is justified, and when it becomes dangerous, remains an open question. Questions to Consider • What factors most strongly shape trust in institutions, performance, transparency, shared identity, or something else? • Is declining trust primarily a problem, or can it be a healthy corrective? • Are some institutions, such as courts, science, or local government, more deserving of baseline trust than others? • How should societies respond when large portions of the public lose faith in elections, media, or public health guidance? • Can trust be rebuilt once it is lost, and if so, how? • Does technology, especially social media and AI, strengthen or weaken institutional legitimacy?

Combined with our [LLM scaffolds](https://dlthub.com/workspace) and [MCP server](https://dlthub.com/docs/hub/features/mcp-server), you can build a custom connector for any of the 8k+ available sources in 10 minutes by following this guide. Building with LLMs is an iterative process. We will follow this general workflow and give practical tips for each step."
