_______________ **Resumen:** Integrar modelos de aprendizaje profundo de Keras en el ecosistema Tidymodels ha sido tradicionalmente como mezclar agua y aceite: Keras es imperativo y basado en grafos, mientras que Tidymodels es declarativo y espera argumentos de configuración fijos. Esta charla presenta kerasnip, un paquete de R que une ambos mundos tratando la topología de la red neuronal como un hiperparámetro más. Se demuestra cómo usar "Bloques de Modelo" y especificaciones dinámicas para ajustar estructura del modelo, como la profundidad, el ancho y las ramificaciones de la red, utilizando herramientas estándar como tune_grid(). Aprenderá a definir planos de modelos flexibles que exponen su estructura como "diales" ajustables, llevando la capacidade de crear modelos complejos de Keras a Tidymodels.

He construido mi carrera sobre desarrollo de software, ingeniería de sistemas y arquitectura de software en la industria de las telecomunicaciones. Posteriormente, me uní a Red Hat como PM para proyectos de observabilidad como OpenTelemetry, trazado distribuido, Jaeger, Tempo y Kepler. Mi objetivo es generar un impacto real construyendo comunidad a través del intercambio de conocimiento: enseñando a quienes se inician, participando en actividades de mentoría, entrevistando candidatos y diseñando programas de aprendizaje. **Descripción de la charla:** Cuando se trata de escalar soluciones de monitorización de series temporales, las cosas pueden volverse un caos. Esa es una de las razones por las que VictoriaMetrics, miembro Silver de la Cloud Native Computing Foundation (CNCF), comenzó su recorrido hace algunos años. Es un conjunto de soluciones de observabilidad simple, fiable y eficiente, adoptado por muchas organizaciones. Es de código abierto, con una comunidad sólida detrás, y ofrece opciones enterprise y gestionadas (Cloud) para quienes necesitan soporte. VictoriaMetrics se integra muy bien con muchos estándares, incluyendo Grafana y OpenTelemetry. Además, por si no lo sabías, VictoriaLogs es el nuevo jugador del mercado y está superando seriamente a otras soluciones. En esta presentación, mostraremos los proyectos Open Source de VictoriaMetrics y en qué se diferencian de otras soluciones, especialmente cuando se trata de escalar desde instalaciones pequeñas y sencillas hasta despliegues masivos en clúster. ¡Ven a descubrir cómo los proyectos de VictoriaMetrics pueden hacer la observabilidad mucho más fácil! *** Si aún no te has unido a la comunidad de Discord, ¡por favor, hazlo!

**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!

#### Turning Rentals Into Income: How Investors Pay Off Properties Faster #### **Featuring Guest Speaker: John Blackburn** **👉 Get your FREE TICKET [HERE](https://www.eventbrite.com/e/turning-rentals-into-income-how-investors-pay-off-properties-faster-tickets-1980492192461?aff=cicmeetupapp)** #### A lot of people get into real estate because they want freedom. Then they buy a rental…and realize most of the rent goes straight to the bank. They technically own property, but the mortgage controls the income. And waiting 30 years for properties to be paid off doesn’t feel realistic. This meetup is about understanding a different way to think about rental properties… one that focuses on paying them off sooner so the income is actually usable. **Featured Guest Speaker: John Blackburn** We’re excited to welcome John Blackburn as our guest speaker for this event. John has been actively investing in real estate since 2006 and has: * Been involved in **5,000+ real estate transactions** * Helped investors **acquire over $150 million in rental property** * **Raised more than $100 million** in private capital John didn’t start with family money or shortcuts. He built his portfolio by focusing on clear systems, real numbers, and long-term strategy. For this meetup, John will walk through how investors shift their focus from simply owning rentals to building properties that eventually pay them…without a mortgage attached. **What You’ll Learn** John will break down, in simple terms: * Why most rental properties don’t produce much usable income early on * Why buying more rentals isn’t always the answer * How investors structure their properties to pay off mortgages in a fraction of the time * How properties can work together to eliminate debt faster * What changes once rentals become free and clear This approach is often referred to as an accelerated paydown strategy — using rental income intentionally to reduce debt sooner, rather than waiting decades for mortgages to run their course. John will also share a simple calculator you can use to see how this works with real numbers and realistic scenarios. **The Core Idea** When a rental has a mortgage, the rent has one job: **pay the bank.** When a rental is paid off, the rent has a different job: **pay you.** Most people only see one timeline…30 years. This session shows how investors shorten that timeline and gradually increase their income as properties become free and clear. **Who This Event Is For** This event is for people who want more than just “owning rentals” on paper. * Rental owners who are tired of most of the rent going to the bank and want a clearer path to real, usable income * New investors who want to understand how rental properties actually build wealth over time before jumping in * People with capital who want to invest in real estate with intention and a long-term plan * Anyone serious about freedom and curious how rental properties transition from debt-heavy assets into income-producing ones **Event Details** **Location:** Ohio Brewing Company - 421 E 2nd Ave, Columbus, OH 43201 **Date & Time:** January 25th, 6–8 PM (Doors open at 5:30) **Cost:** Free (Seats are limited - RSVP required) **👉 Get your FREE TICKET [HERE](https://www.eventbrite.com/e/turning-rentals-into-income-how-investors-pay-off-properties-faster-tickets-1980492192461?aff=cicmeetupapp)** If you’ve ever wondered how rental properties actually turn into freedom —this is the room to be in.

We'll play board games at the [Land-Grant Brewing Company](https://landgrantbrewing.com/). The brewery has multiple [food trucks](https://landgrantbrewing.com/food/) on Sundays, including [Ray Ray's Hog Pit](https://rayrayshogpit.com/franklinton), [Buck City Sammies](https://www.buckcitysammies.com/menu), and [Hai Poké](https://www.haipokefoodtruck.com/). The brewery also has (passable) drip coffee, free water, and Jeni's ice cream. You can also walk over to the [Land Grant Extension](https://callinyourbluffcoffee.com/) for "real" coffee. (You may have to stand in line, though. The Extension is popular.) You can come late or leave early. Please just sign up so I know to expect you. **Notes on Parking** * You'll (probably) have to park on the street, but street parking is free on Sundays. * There are [parking garages](https://landgrantbrewing.com/parking/) a little farther away if you want. These are obviously not free, though. * There is a [lot next door](https://www.google.com/maps/place/39%C2%B057'26.0%22N+83%C2%B000'40.9%22W/@39.957211,-83.0119921,19z/data=!3m1!4b1!4m12!1m7!3m6!1s0x88388f3efd89238b:0xc139207386232411!2sLand-Grant+Brewing+Company!8m2!3d39.9577613!4d-83.011426!16s%2Fg%2F1pzt7t9df!3m3!8m2!3d39.957211!4d-83.011347?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) to the brewery that you're allowed to park in, but it is not free. I've never parked there, so I don't know anything about rates. (I'm told though that if you eat at Milo's Deli next door to this lot that Milo's will stamp your parking so it's free.) * You're going to see odd signs on [Lucas St](https://www.google.com/maps/place/39%C2%B057'26.1%22N+83%C2%B000'40.3%22W/@39.957256,-83.0124134,19z/data=!3m1!4b1!4m10!1m5!3m4!2zMznCsDU3JzI4LjgiTiA4M8KwMDAnNDEuNSJX!8m2!3d39.957993!4d-83.011536!3m3!8m2!3d39.957256!4d-83.011197?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) (saying it's a "private street") that will lead you to believe you're not allowed to park there, but you actually are. * Columbus parking cops literally do not work on Sundays. This means that, even if you're driving a non-EV, you can park in the EV spots near the brewery. **Games** I do bring many games, but please bring some of your own as well.

Join us for something different as we get together to see EPIC: ELVIS PRESLEY IN CONCERT! While researching his 2022 film, director Bas Luhrmann came across and compiled rare and previously unseen interviews and videos of Elvis in concert to create “one of the most exciting concert films you’ve ever seen!” Here are details, a trailer and our plan for this event: DESCRIPTION: Part documentary, part concert film, the latest from director Bas Luhrmann is a follow-up to his 2022 film starring Austin Butler. While researching the film, he came across 68 boxes of previously unseen interviews, concert performances and outtakes from previous films. A combination of offstage and onstage Elvis, comes a film that “befits the magnitude of Elvis as a performer but also offers deeper revelations of his humanity and inner life." It is written/directed by Baz Luhrmann (ELVIS, MOULIN ROUGE, THE GREAT GATSBY) and stars the legendary Elvis Presley! TRAILER: https://www.youtube.com/watch?v=NmqWusmzp0k BUZZ AND ACCLAIM: The film screened at the 2025 Toronto Film Festival where it was the runner up in the category People’s Choice Award for Documentaries. Next Best Picture says, “Certain to energize longtime fans and generate new ones for generations to come, EPiC: Elvis Presley in Concert is a masterwork of montage.” And according to the NY Post, whether you have a room in the house devoted to Elvis or not, this truly “Epic” concert film is an energizing experience!” PLAN: We’ll plan for a pre-show bite at nearby BRAVO around 5 or 5:30pm followed by a 7pm-ish showing on one of their larger screens. Once showtime is announced, advance ticket purchase is advised. Please list your seat number in the Comments below. Exact showtime and meeting details will be confirmed/announced as the date gets closer. Look forward to seeing you there, Dan
