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.

This panel from the Nonprofit world brings together people who have actually done it. They will share what worked, what did not, and how they figured it out without huge budgets or dedicated tech teams. You will hear honest stories about implementation, the challenges that come up, and what actually moves the needle.

ike Turkey Run Park- Pho Lunch, VA Sunday March 8 With winter weather receding, this is a great way to fight cabin fever and head back outside with views of the Potomac. This is a 3 to 4 mile loop hike along the Potomac River just below the American Legion bridge off the GW parkway. The trail is mostly easy and flat, but there are some slightly rocky areas. Be aware that this time of year where segments along the river can be muddy and there are some rocky areas we must maneuver around. Bring a mascot! The park is dog-friendly, but must be on a leash.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
