Hardware Hacking and Reverse Engineering

This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

***Join us for a day in an electronics lab, as we attempt to finalize the system, and run scans for atoms.*** We will likely not succeed on our first attempt - but we still plan to put the time in. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) 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. 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 will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

The long promised REIKI two training is now available. I will be providing an agenda in the very near future. This is a placeholder for those who are interested in taking the REIKI training class with me. The fee for this class will be donation based. Feel free to contribute what you feel you have gained from the course and the value of that knowledge. See you soon! Shaman Phil

Reclaim your soul’s truth.** Beneath all the noise, the patterns, and the pain, your soul has never stopped whispering. It holds the memory of every choice, every wound, every triumph across time. This vibrational archive—your Akashic Records—awaits you. And within them: clarity, healing, and a return to the Divine spark of who you truly are. Let’s take a breath and reflect… \~Have you been feeling like you're moving through life in a loop—taking one step forward, only to be pulled back again and again? \~Does life feel like an ongoing storm of confusion, struggle, or emotional unrest? \~Do you long for heartfelt, soul-level connection—but feel it remains just out of reach? \~Are you living the life your heart calls you to…or the one others expect? **If you’ve felt this, take comfort: you are not broken. You are awakening. You’ve been guided to this moment for a reason. Your soul knows it's time to return home to your truth.** **\*\*Welcome to the Akashic Records\*\* a timeless sanctuary of compassion, wisdom, and love.** In this deeply healing workshop, you're invited not just to explore your story—but to rewrite its energetic imprint. Guided by the compassionate presence of **Bill Sanda**, you'll step into a space where healing is not only possible, but inevitable—when met with an open heart. This isn’t just another offering. This is a soul-remembrance. During our time together, you will: ✨ **Uncover the hidden patterns of your past**, including the emotional echoes, ancestral threads, and past-life imprints that continue to influence your present reality ✨ **Liberate yourself from repetitive cycles** of fear, doubt, or stagnation, so you can move forward in alignment with your soul’s highest expression ✨ **Receive healing directly from your Akashic Records**, reconnecting to your innate wisdom and Divine blueprint ✨ **Remember who you are beyond this lifetime**, as insights from past incarnations help you navigate your current path with grace ✨ **Experience the sacred sound of Light Language**—a celestial, soul-coded vibration that speaks beyond the mind, clearing density, activating remembrance, and harmonizing your energy at the DNA level Bill’s sacred gift of channeling the Akashic Records—woven together with the high-frequency transmission of Light Language—creates a multidimensional space for profound transformation. You’ll also receive personal attention during the workshop through mini-healing sessions, and we'll culminate in a group integration, inviting a collective shift in vibration and consciousness.

The shift happening for each person was actually physically visible.”* — *Cindy W.* *“Finally, I understand what has been causing the sabotaging behaviors. Two days later, I’m clearer and more spiritually connected than I’ve ever been. Thank you, Bill, for your healing gifts.”* — *Wendy W.* ***About Bill Sanda*** *A lifelong seeker and heart-led healer, **Bill Sanda** walks with humility, clarity, and deep reverence for the sacred. His journey has led him to study with some of today’s most respected spiritual masters, but it was through divine revelation that his ability to work within the Akashic Records and transmit Light Language fully emerged.* *Bill now offers this work as a gift of service—to support others in awakening to their truth, releasing what no longer serves, and remembering the wholeness that has always been within. His mission is simple and powerful: to support your healing on all levels—**emotional, physical, mental, and spiritual**—so you can live more aligned, more free, and more fully alive.* **Investment: $75** Pre-registration and Payment required: [https://www.wellnessliving.com/rs/event/teal_center?k_class=919488](https://www.wellnessliving.com/rs/event/teal_center?k_class=919488)

**This talk has completely sold out in advance and no door tickets will be available. It also is being staged at Penn Social in DC on March 17th, and tickets remain available then.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Ireland’s Fight for Freedom,”** with Kevin Matthews, assistant professor of history at George Mason University and former London correspondent for Vatican Radio reporting on British and Irish news. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom) .] After centuries of struggle, Irish men and women won their freedom from Great Britain after waging a war that set the pattern for all other independence struggles of the 20th century. But there was a price—the partition of their country, a split setting the stage for the Northern Ireland “Troubles” that didn’t end until 1998. Gain a deeper understanding of Ireland and its history with Professor Kevin Matthews, a historian and frequent Smithsonian Associates speaker who had served as a journalist covering the last stages of the Troubles in Ireland in the early and mid 1990s. He’ll discuss in depth how the Irish won independence in a two-year war between 1919 and 1921, covering topics as the role women played in the conflict, the life and tactics of the revolutionary leader Michael Collins, and the Irish development of “urban guerilla warfare” using small, highly mobile armed units called “flying columns.” Most important, this talk will examine how the conflict between Irish nationalists and Irish unionists led to Ireland’s division and later conflict. From the Easter Rising to the Good Friday Agreement, from Bloody Sunday to Brexit, this conflict has never quite gone away. As the Irish poet, William Butler Yeats once wrote: Now and in time to be, Wherever green is worn, Are changed, changed utterly: A terrible beauty is born. Professor Matthews will explore how the Irish fought to a standstill what was then the mightiest empire in the world and how, more than he could have known, Yeats’ prediction still rings true today. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Members of the Irish Republican Army’s West Connemara Flying Column in 1921.

**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: * What is the exact definition of the Subconscious Mind? * How does it inflict unwanted feelings and anxiety in you? * What determines how much pressure it exerts on a person? * What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center.

Projects that are over budget, delayed, or that fail to scale past the POC phase are very common. In many of these scenarios, choosing the right approach can be as critical as the solution itself. Should you build a tailored machine learning model, leverage the power of large language models (LLMs), or integrate with AI copilots? Each option has unique strengths, trade-offs, and resource requirements, and the key to success lies in aligning your choice with your business goals and technical constraints. In this talk, we will go beyond the basic concepts and definitions to provide a practical guide that allows attendees to navigate these decisions through real-world case studies. We will examine scenarios in which different AI paradigms were chosen, discuss the factors that influenced those decisions, and outline the process for evaluating needs, constraints, and outcomes. From assessing data availability and team expertise to balancing cost and scalability, you'll gain insights into the critical considerations that guide the selection process. By the end of this session, you’ll have a clear process for determining whether machine learning, LLMs, or copilots are best suited to your AI challenges and understand the resources and strategies needed to bring your chosen solution to life. This talk is ideal for decision-makers, technical leads, and innovators seeking to demystify AI implementation and maximize the impact of their investments.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is sponsored the Dianetics & Scientology Self-Improvement Center.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This class is held at the Dianetics and Scientology Life Improvement Center.
