MDC DSA’s Labor Magazine Discussion Club seeks to provide a monthly discussion space to think through and debate tactics, strategy, and theoretical analysis within the currently existing Labor movement. We hope to be a nerve center for germinating new and incisive analysis useful for the cause of workers self-emancipation. All are welcome to join the club’s meeting, where we will discuss 3 articles from labor magazines currently circulating. For more details and links to the readings, check out [the group's info doc](https://docs.google.com/document/d/1rq5JzlubZrLNML0EbGUHiNvXNC42VRz8bmJgLH4GE-s/edit?tab=t.0).

***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. We are getting close. Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

Western Market is allowing us to use the space for free. Please reciprocate by purchasing something, even if it is just a soda. Directions If you're taking the Orange, Silver, or Blue lines, exit at the Foggy Bottom metro station and walk two blocks to the east. If you are taking the Red Line, Farragut North is an approximately a 15 minute walk away. There is also free street parking to the north.

Looking for a fun, screen-free way to spend your Sunday afternoon? Join us every other week at the Community Center for a few hours of friendly competition and laughter.

Please ensure children have a parent or guardian joining in on the fun.

A favorite of the DMV's swing dance community, the Rock-A-Sonics play a mix of Rockabilly, 50's rock and country, and Western swing. Frontman Willie Barry's pure tenor is accompanied by a group of very talented musicians. Tommy Joe's in downtown Bethesda occupies the second and third floor of corner building. Bands play the second floor and there's no cover. It's easily accessible by metro or car (I use parking garage 36 Auburn- Del Ray).

Every Second Sunday of the Month from 1-2 pm EST In this class Bebe Blumenthal helps kids learn to play music together. Kids have the opportunity to play the tunes they are learning in your private lessons with others - and learn new songs from others. Importantly kids learn how to collaborate, communicate, create and play well with others in a jam session. Mari facilitates a fun and supportive environment that encourages flexibility, experimentation, and listening. Parents and older siblings with accompanying instruments are welcome to sit in and support the jam. $30/session. Come every month or just once. Who knows - maybe you’ll meet future bandmates… [https://checkout.square.site/buy/RKAXL7VL3DZTFMNRJ2QOTQAT](https://l.facebook.com/l.php?u=https%3A%2F%2Fcheckout.square.site%2Fbuy%2FRKAXL7VL3DZTFMNRJ2QOTQAT%3Ffbclid%3DIwZXh0bgNhZW0CMTAAYnJpZBExOGhVQ2k0b2g0Tkh0MkNJTgEe8n49Ur8UheXrPvV9tuqM9tHt7roV98z1uB9noLudWMLlGXQDFlw9uplVnEk_aem_tGa34dgHF9MSrLXbb3lJxg&h=AT0dRLI4rVUl4bpQG_DUh9my34Zc_nc4xrFSTZrbKY8iqah0tWA_L6CPexeirKBgawv1CoAIsCbPUWkpkqjH74hlJavr9GuxTggxel-v635cTHs8JDc7d0oqeHoNCoaGZ4eamYckH-ucuJwzHmDtD9MXPFKK30JtqAI&__tn__=q&c%5B0%5D=AT1bMR07rIyK5Sln0FvxJp3kCXsOFI0bRjYhJoQFYiISS6ePbzbNOLMZndtLzCHE0LnQuGmPDdjpU9Sg_hbbC66Rosb2PKruxXGUvoqBrtp7ghRWCK654ffbPTXGNSDtE56KHG77JcCqwD-AyDdBOiZanG8pjte1eTQ)

For James Taylor's birthday, let's sing a few of his songs that are not in the Rise Up books. See you at SOJO! Seasoned SOJO'ers already know the program, but below are all the details which may be helpful to our new members. MOST IMPORTANT POINTS: 1. If you have copies of Rise Up Singing and Rise Again, please bring them. If you don't, we may have some extras available for you to borrow (one time only, please). Both books are easy to find and order online. And here's a link to find YouTube Videos of any song in either book. https://www.riseupandsing.org/songs/search 2. Feel free to bring lyrics and chords to hand out for songs not in the books. If you'd like to bring a song that most people don't know well, see if you can find a YouTube link and post it in the comments when you RSVP. We'd like to listen a few times before the SOJO to get the hang of it. 3. Bring something to drink, as singing is likely to make you thirsty. 4. We appreciate (but do not require) contributions to cover our room rental costs of $75 per session. 5. Please do RSVP. It helps us know how to set up the room and allows us to contact you if we have to cancel. *** FURTHER DETAILS, if you like: * Our regular gatherings take place on the 1st and 3rd Saturdays of the month. We meet from 2 to 5 p.m. with a break around 3:30. You can come for the whole time or just part of it. If you can arrive a little early to help set up or stay a little late to help put things back in order, that would be great. Occasionally we take pictures of our events. If you would rather not be photographed, just politely let the person with the camera know and step out of view. We'll be respectful of your wishes. Whether you're new to SOJO or not so new, we look forward to singing and playing with you!

The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~$20 per person. Soft drink refills are $1 each. Please support our hosts so we can continue to provide great events for the group! The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play. Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes. We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can be challenging. There is a parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. *** Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ).

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.
