This romantic social experiment transforms the 42nd Street Shuttle (S Train) into a mobile venue for serendipitous connection. By participating, commuters signal their openness to romance through a simple floral code: a **red rose** for men and a **white rose** for women. The Floral Protocol * **The Signal:** Wear your designated rose clearly on your lapel or hold it in your hand while traveling between **Times Square** and **Grand Central**. * **The Connection:** Maintain intentional eye contact to confirm mutual interest. * **The Proposal:** In a gesture of classic chivalry, the man may drop to one knee. * **The Acceptance:** If the woman accepts the gesture, she gently assists him back to his feet, followed by a celebratory kiss to mark the beginning of their shared story. Plan Your Route The shuttle runs continuously, making it easy to participate at any time. You can check real-time service status on the MTA Official Website to ensure a smooth journey. After a successful connection, many couples choose to celebrate their first moments together at the iconic **Grand Central Terminal**, which offers various dining options listed on the Grand Central Dining Directory. \-\-\- **El Ritual de Conexión** **El Código de Vestimenta:** Los hombres llevan o visten una rosa roja 🌹; las mujeres llevan o visten una rosa blanca. **La Chispa:** Entre el ajetreo del Tren S (Lanzadera), busca a tu contraparte floral. Cuando encuentres a alguien que cautive tu corazón, mantén la mirada para cerrar la brecha entre extraños. **El Gesto:** Tras la señal silenciosa, el hombre se pone de rodillas en el suelo del vagón—un tributo audaz y clásico a la mujer frente a él. **La Unión:** Para aceptar, la mujer toma suavemente su mano para ayudarlo a levantarse, sellando el momento con un beso mientras el tren avanza hacia su destino. **El Comienzo de Tu Historia** Una vez que bajes del andén, no dejes que el impulso se desvanezca. * **Celebra el Momento:** Haz la transición del metro a la grandeza de la Terminal Grand Central. Puedes encontrar un rincón tranquilo para su primera conversación real consultando el Mapa de Grand Central Terminal. * **Una Primera Cita Cerca:** Si la chispa es inmediata, toma un cóctel en el histórico Campbell Bar o un café en una de las muchas cafeterías de la terminal. * **Logística del Viajero:** Asegúrate de que tu encuentro romántico no se vea interrumpido por retrasos verificando el Estado del MTA Shuttle antes de salir con tu rosa.

For the FIRST time ever, we have a GUEST teacher, Charlotte, talking about the powerful Astrological events taking place February 17th AND a first ever New Moon manifestation ritual!

Calling astrologers and astrological enthusiasts to an informal celebration of the Saturn Neptune conjunction at 0 degrees of Aries. Let’s gather to have a drink in a common space and chat about the next 36 years of our lives. Yes, this date marks the official beginning of a 36 year cycle wherein we will make our individual dreams (Neptune) come true (Saturn). Over the next 36 years, we will watch as what happens TODAY will grow, flourish, peak, and gently come to an end. At the time of this event, the planets will already be in a new phase to each other, which signals the past is gone, the future starts here and now, together, with a spark of a present moment intention- acted on. This happens in the tropical sign of Aries which is about pure existence, right now. We are building out nothing more than the fullness of this present moment, affirming our worthiness, existence, here and now. Mars, the ruler of Aries, is in the sign of Aquarius at the time of this conjunction which reflects that this cycle will have everything to do with the efforts and collective will of our communities- so we gather to make it happen! For this informal two hour event, you will be invited to chat with others about collective astrology, personal astrology, the dreams you’re building within yourself, in the present moment, and within your communities. Guidance and prompts will be offered. Personal Birth Charts can be calculated for those who don’t have them for themselves. Where is Saturn in your birth chart? What reality do you build through your work? Where is Neptune in your birth chart? What is your ideal vision of the world? How do you see yourself living as an expression of your ideal vision in the world? This is a space for folks of all types and levels of astrological knowledge. Astrology is a practice to serve greater clarity of the natural patterings of our life, not to be resisted nor sensationalized. It is a practice to see ourselves from outside ourselves from a space of unconditional love. Event Host: Julianne Thomson, evolutionary astrologer and painter. @brightsideastrology

Regroup at a bar nearby ([Old Town Bar](https://maps.app.goo.gl/2kigoa6ZMbgC1scG8)) **First Talk Description:** • The Bar is on Which Floor? Improving Altitude and Floor Detection Liam Meier, Director of Engineering at Radar iOS can estimate a device's altitude. In real world conditions, this estimate is far less accurate and reliable than horizontal (lat/lng) positioning, which makes the question "which floor is someone on?" hard to answer. Leveraging little known sensors in mobile phones and clever correction techniques enabled by at-scale deployments, we're able to determine mobile device altitude and floor level with markedly higher accuracy than what's available today. Liam Meier is Director of Engineering at Radar, where he leads the team behind Radar’s leading geolocation platform and mobile SDKs, deployed on over 300 million devices. Previously, he founded and built products at early-stage startups. In a past life, he studied galaxy formation under the influence of dark matter — helpful training for making sense of noisy sensor data. **Second Talk Description:** • Beyond the Sandbox: Secure iOS Development in an Era of New Security Standards Mike Sanderson Even as mobile apps have come to handle sensitive medical, financial, and personal information, the practices of secure mobile app development has remained a patchwork of received wisdom and platform constraints, with developers who want to practice secure development are often unclear on how to do so or what that even means. In the past few years, leaders in security standards have increasingly seen the need to for digital security incorporate secure coding earlier into the software development process, known as "shift left," and included references to systematic cybersecurity standards. This talk will look at how secure mobile app development fits into the larger security picture, including the security of the iOS platform and the MacOS platform apps are developed on. The talk will look at sources for guidance for secure iOS software development, in particular the OWASP flagship Mobile App Security project and other OWASP efforts. The idea will be to start to equip iOS developers not only to make good decisions but to systematically identify best practices and understand how they fit into the larger security picture. Mike Sanderson is a writer and computer programmer who has worked on iOS apps full-time since 2013, including working with a launch partner of Apple Wallet in iOS 9, working on a secure message app at scale, and independently finding and reporting an authentication-bypass bug on a medical iOS app, which was confirmed. Recently, Mike has provided comments on several National Institute of Standards and Technology (NIST) draft papers related to cybersecurity. **Location:** 111 5th Avenue Floor 12 New York, NY 10003 Please enter through the main lobby on 5th avenue, next to H&M.
