Systems

Can crime be predicted by algorithms? And if so, should we use them to prevent crimes from happening? This question has fueled many dystopian works of fiction, such as **Minority Report**, which imagines a technology capable of predicting crimes in precise detail and raises fundamental questions about free will and individual responsibility. **Person of Interest** explores a more realistic scenario, where machine learning and mass surveillance are used to identify high-risk individuals through the monitoring of communications. Many episodes of **Black Mirror** similarly examine the consequences of predictive technologies and their impact on privacy, liberty, and social control. A common theme emerges from these stories: such technologies are often portrayed not as tools of public safety, but as threats to freedom and democracy. Yet the idea is not purely fictional. While no system today can predict crimes with the certainty depicted in science fiction, predictive algorithms are already being used in various aspects of law enforcement and criminal justice. **COMPAS**, for example, has been used in American courts to estimate the likelihood that a defendant will reoffend. **Geolitica**, formerly known as **PredPol**, uses historical crime data to forecast crime hotspots and guide police deployment. More broadly, advances in artificial intelligence, big data, and digital surveillance continue to expand our ability to identify patterns in human behavior. Some even point to the Chinese **Social Credit System** as an example of how large-scale data collection can be used to monitor and influence citizens. Now that the technological capabilities have already been laid out, should we, as a society, pursue the endeavor of developing a predictive algorithm that would allow us to prevent crime? Or is there a moral imperative that prevents us from doing so? Join us as we debate whether predictive crime technology represents the future of public safety or the first step toward a surveillance dystopia. This debate will follow a British Parliamentary format with eight debaters split into **four teams of two.** Participants who wish to speak are highly encouraged to bring a paper and pen. You are welcome to participate even if you have no prior debating experience. We aim for debates that are respectful, constructive, and welcoming: * **Respect ideas and people** Listen actively, stay quiet while others speak, and debate arguments, not identities or beliefs. * **Be concise and civil** Keep questions short and relevant; avoid hostility, hate speech, or discrimination. * **Respect boundaries and time** No unwanted advances or suggestive behavior; arrive on time to avoid disrupting the debate. * **Follow moderators** They guide the discussion and ensure fairness.

The IO system in Linux has gone through many changes over the last decades. In this talk, we'll go through the history and the reasons why it evolved: what problems were solved, how, and where are we today? We will wrap it up by comparing the current state of IO in Linux, i.e. epoll and io_uring, and how this relates to the Rust ecosystem: while Tokio is the most famous asynchronous runtime and executor for Rust programs, there exists alternatives: for even better performance you might want to try an alternative runtime like [CompIO](https://compio.rs/). We will go through some examples, and relate the performance optimizations to the choices it makes on how it does IO. Will be presented by [Koen](https://www.linkedin.com/in/koen-de-keyser/) from DoubleVerify.

**First time comers** Please make sure to read the rules and contact the organizer before! Otherwise you will be moved to waiting list. Apologies for inconvenience but we have to do it to avoid no-shows. **Games format.** 95% are double games (unless someone needs a break), typically 4 people play together 2 sets and then mix with players from other fields. We play with plastic shuttles - Yonex Mavis 2000 (which are provided). **Registration** If it's your first time, please send a private message to the host to confirm. No-shows are taken quite seriously because they unbalance the games a lot. Also once you register please keep an eye on you private messages, in case we need to contact you. **Players level** Having players with much less experience often unbalances the game making it much less interesting for more experienced players. We still try to be welcoming. As a rule of thumb, if you know what a "clear" is, you are welcome to join. (Note that on Sundays the attitude is a bit more relaxed than on Wednesdays, it's the weekend after all ;) ) Otherwise, feel free to get in touch with me (Timur) and we can see if we can arrange so you and existing players can have good experience playing. **Price and payments** The price of participation is EUR 8.95. Payment is on-site in cash, or via payconiq. Info provided during or shortly after the event. **Cancelations and no-shows** * Switches and cancellations are free of charge if done more than 50 hours before the start of the matches * If you cancel within the 50-hour window before the event starts, you will be placed on the wait-list for the next week's event, whether or not a replacement is found. If no replacement is secured, you'll still need to cover your share of the costs.

For decades, application security has been built around a simple assumption: humans are the primary producers of software. We train developers, review their pull requests, model threats in design meetings, and build controls around human decision-making. That assumption is rapidly breaking down. As AI coding assistants evolve into autonomous software agents, organizations will gain access to an effectively unlimited engineering workforce capable of producing software at a speed no human team can match. The pressure to adopt these systems will be driven not by curiosity, but by competition. Companies that successfully harness agentic development will ship faster, iterate faster, and potentially outpace those that do not. This shift forces a fundamental rethinking of application security. The future of AppSec is not securing developers—it is governing an agentic workforce. Threat modeling, code review, security testing, and change management will not disappear, but they will need to operate at machine speed and increasingly be performed by systems rather than people. In this talk, Ken Johnson, CTO of DryRun Security, explores what the next decade of application security may look like, the assumptions that will no longer hold, and why security professionals must understand these systems deeply if they hope to influence the future rather than react to it.

**The Neural Revolution Is Happening Right Now — Are You Plugged In?** Imagine typing with your thoughts. Steering a robotic limb with a neural signal. Lifting depression by stimulating a single brain circuit. Loading a skill straight into memory. This isn't science fiction. It's happening in labs, clinics, and startups around the world — and the DC region, home to NIH, the BRAIN Initiative, and DARPA's neural-interface programs, is one of the places it's being funded and built. **This Event Is for You If…** * ✅ You're a **technologist** curious about the computing paradigm beyond screens and keyboards * ✅ You work in **healthcare** and want to see how neural interfaces will reshape patient care * ✅ You're an **entrepreneur** hunting the next real opportunity in deep tech * ✅ You're a **researcher** looking to plug into the broader BCI ecosystem * ✅ You're simply **fascinated** by where neuroscience and technology collide * ✅ You **missed our last meetup** and want to reconnect with the community **Why That List Makes Us Unique in DC** Read it again. A technologist, a clinician, a founder, a researcher, and the merely curious — in the same room, on the same afternoon. That mix is the whole point, and it's what no other event in the region offers. Neuroscience conferences are built for neuroscientists. AI meetups are built for engineers. Healthcare summits are built for clinicians. Each one serves a single silo. Brain computing doesn't live in any one of those silos — it lives in the overlap. So we built the one community in DC dedicated to that overlap: a place where the person decoding neural signals can talk to the person who'll commercialize the device, who can talk to the clinician who'll put it in front of a patient. **What You'll Walk Away With** This isn't just another tech meetup. Because of who's in the room, you get: * **Frontline insight** from people actively decoding neural signals * **Direct access** to the scientists, engineers, and founders pushing BCI forward — not a panel behind a rope line * **Hands-on work** with real neural data and BCI systems * **Career connections** in one of the fastest-growing fields in tech * **First looks** at breakthrough research before it reaches mainstream media **The Stakes Are Real** We're at an inflection point. The next decade decides whether brain-computer interfaces *expand* human potential or *deepen* inequality — whether they're built in the open or behind closed doors, whether the benefits are shared or hoarded. Your voice, your expertise, your perspective shapes which future we get. **Join the Minds Shaping Tomorrow** This is your entry point into the neural-interface revolution — your chance to stand alongside the researchers reading neural code, the engineers building the interfaces, the clinicians treating patients, and the founders bringing it all to market. **Saturday, June 13 · 12:00–3:00 PM** isn't just a meetup. It's the one place in DC where all of those people come together around brain computing. **Come curious. Leave connected. Return transformed.** Because the future of human-computer interaction isn't happening *to* you — it's happening *with* you.

Important: Register on [AICamp website](https://www.aicamp.ai/event/eventdetails/W2026061814) is required for admission. **Description:** Welcome to the AI meetup in Washington DC. Join us for deep dive tech talks on AI, GenAI, LLMs and Agents, hands-on experiences on code labs, workshops, and networking with speakers and fellow developers. **Agenda:** \* 5:30pm\~6:00pm: Checkin, Food/drink and networking \* 6:00pm\~8:00pm: Tech talks and Q&A \* 8:00pm: Happy Hour at Courthouse Social (cross the street) **Tech Talk: Secure Developer Environments in the Age of AI Agents** **Speaker:** Patrick Brown (Coder) **Abstract:** Federal engineering teams are under pressure to ship faster while meeting some of the most demanding security and compliance requirements in the world. In this talk, Patrick Brown of Coder explores how cloud development environments (CDEs) give agencies a foundation to accelerate software delivery without sacrificing control — and why that foundation matters even more as AI-powered coding agents enter the workflow. He'll cover how CDEs keep source code off endpoints, enforce zero-trust access patterns, and provide the consistent, ephemeral infrastructure that both human developers and AI agents need to operate safely at scale. **Speakers:** Stay tuned as we are updating speakers and schedules. If you have a keen interest in speaking to our community, we invite you to submit topics for consideration: [Submit Topics](https://forms.gle/JkMt91CZRtoJBSFUA) **Sponsors:** We are actively seeking sponsors to support AI developers community. Whether it is by offering venue spaces, providing food, or cash sponsorship. Sponsors will not only speak at the meetups, receive prominent recognition, but also gain exposure to our extensive membership base of 5,000+ AI developers in D.C and 500K+ worldwide.
