Please do not arrange to play earlier than the scheduled start time UNLESS you are able to stay till the end of the event, we do not want people leaving early and creating uneven numbers. Hello members, Tennis has become much more popular since the pandemic started and court space has been harder to come by. Following these simple rules will help everyone get the most out of MoCo Topspinners Meetup. • If you RSVP for an event, please attend that event or cancel at least two hours before the event starts. Members that no-show will receive one warning then will be benched (suspended) from events for two weeks. Three no-shows can result in a permanent ban. (No-shows create uneven numbers and prevent folks on the waitlist from playing. Please do your part to un-RSVP as soon as you know that you cannot attend an event.) • Members must have a way to communicate with organizers and hosts. This can be through the Meetup app messages or by providing other contact info. • Any member can ask a host or organizer to have their skill rated for event attendance purposes. You will not be allowed to participate in events higher than your NTRP rating. (We may try to limit numbers or have multiple events on a given day to accommodate players of different skill levels and also to help alleviate the court availability problem). • All members shall conduct good sportsmanship and be courteous to other members at all times. • Sexual harassment, racism, sexism or any kind of intolerance will not be tolerated and will result in the permanent ban from the group. • If member receives three warning infractions, the member will be suspended from the Meetup for a period of one month. If a member is suspended twice (six warnings), that member will be permanently banned and any membership dues will then be forfeited. • If you are scheduling to play with others outside of a MoCo Topspinners event, and you know that there is a MoCo Topspinners event scheduled for that day at that time, please try to use courts other than the courts where the event is scheduled, or move your time so that it does not conflict with the Topspinners event. For a list of complete rules and definitions you can see the MoCo Topspinners front page. If you have questions, don’t hesitate to contact us. We are hoping for a fun season but we may have to wait for courts and leave earlier than we are used to. Please be patient as we adjust to this new normal and try a few different things that will hopefully help the situation. Happy playing! If you would like to attend this event you must be a of minimum 3.0 level. USTA guidelines prior for signing up for the Meetup: https://assets.usta.com/assets/1/15/ExperiencedGuidelines_02142011_V2pdf.pdf Singles and doubles game play flexible depending on court availability. If you have any questions, please feel free to drop the group organizers a message. Looking forward to a great 2021 season- see you on the courts! • What to bring Tennis Balls and Racket, Water.

Title: On Quantizing General Relativity Date: Jan 17 2026 Noon -14:00 EST Summary: Why has a century passed without anyone developing a persuasive, broadly accepted, and experimentally predictive unified theory of quantum mechanics and general relativity? In this presentation, Terry will begin by explaining how Einstein’s post-1911 adoption of the Minkowski concept of an infinitely smooth spacetime fabric destroyed any possibility of such a merger by making spacetime infinitely classical, and thus inherently incompatible with the quantum reality of all forms of matter and energy. Next, Terry will discuss how the concept of infinitely smooth spacetime, in combination with similarly cost-indifferent field theories, wasted a century of theorizing by loading empty space with non-existent, asymptotically infinitely energies that exist only briefly in very-high-energy physics. Finally, Terry will discuss how recognizing that quantum observation is nothing more than acceleration. Terry reframes general relativity as the remnant of relationships remaining after massive observation creates localized instances of spacetime. Speaker: Terry Bollinger is a computer scientist with BS, MS, and professional degrees from the Missouri University of Science and Technology.

First officer Ian will be leading us in some fun board games.

2026 may be the last year many developers write code by hand. We need coding agents to solve complex problems in production codebases, but vibe coding alone won’t get us there. Vibe coding is all gas, no brakes. It burns up the context window until the agent slips on its own slop. You can go fast at first, but the more you stuff into the context window, the more tangled its outputs get. While the industry is rapidly increasing code generation speed, we still have to understand, review, merge, and maintain what gets shipped. This talk featuring Michael Geiger will outline how coding agents (Claude Code + Gas Town) work and a framework for orchestrating them to solve complicated problems in complex codebases. It’s about steering the model: doing the research to align intent, planning the approach up front, implementing in parallel steps, and breaking early. Human judgment still matters, but it should be spent on high-leverage decisions: what to build, what to forbid, and “what is quality?”, not cleaning up slop. Attendees will leave with a checklist to identify workflow and environment gaps that hold agents back, so you and your team can ship higher-quality software starting tomorrow.
