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.

**Our Meetup is off to another hiking adventure! Mt Kilimanjaro, as the tallest mountain in Africa, is included in the 7 Summits of the world.** **It is a bucket-list item for all hard-core hikers and mountain lovers.** We did this trek with Meetup in the summer of 2024 and it was a true experience of a lifetime (see photos below) Let's get to some numbers. It is 5,895m/19,340ft BUT . . . our starting elevation for the trek is 3795m/12541ft As such elevation gain is 2100m/6799ft To compare Everest Base Camp trek, is about 2754m/9035ft elevation change. And Mt Whitney is about 1828m/6000ft elevation change. The key to being able to succeed in this endeavor lays in the route and the support system. We are taking the Lemosho Route via the Northern Circuit. The Northern Circuit route is the longest and newest of the seven established Kilimanjaro routes. It's one of the best routes because it has the best acclimatization profile. This results in one of the highest summit success rates. Add to that stunning views, and comparatively relaxed pace. It is also much less crowded than the other Kilimanjaro routes. As far as our support system: We will be accompanied by experienced guides, porters and cooks. They are certified, ensuring our safety and comfort. Porters will carry our gear. We will have a high ratio of guides to hikers. Our guides will go our pace and support each and everyone of us, regardless of fitness level and pace. In other words...you go your own speed and we all get there safe. More about our trek/trip. As with all our international trips, we picked the best season/time of year to go for weather and wildlife. Lemosho and Northern Circuit is a scenically spectacular and varied route. At the lower elevations it has an abundance of wildlife such as elephant, buffalo, eland and lion which come over to forage during dry season. **Each of our trips is personally crafted to offer the best places and best use of time.** *But I don't have the needed gear?!* You don't need much more than the standard trekker's equipment. We will provide you with a list of what is already included and what can be rented there. *Does this include food?* All meals on the trek potion are included and a cook travels with us! *What is lodging like?* We are sleeping in new and comfortable tents (carried during the day by porters) *I am new at this.* That's OK. We do plenty of prep Zooms before we depart. And in California we have a number of local outdoor day or weekend outings you can test out with us. *How dangerous is this? What if I get sick or hurt?* We will be walking on an established, well used trail the entire time. **Our trip INCLUDES emergency insurance.** We are also Certified Wilderness First Responders and our guides are members of (AMREF) Flying Doctor. **Plain and simple, safety is our primary goal.** *How much does this cost?* **Kilimanjaro Mountain Trek $3950 per person, double occupancy. Land only (airfare not included). Solo supplement $600** Trip Cost includes: \- 9 nights accommodation \- 3 meals everyday on the trek \- All Fees & Entrances and Taxes \- Camping equipment such as tents\, tables\, chairs\. \- Lead Guide\, Assistant Guides\, Porters and Cook *RSVP to this event shows your interest, but does not hold your space.* ***The only way to secure your spot for this trip is a $300 deposit:*** ***[CLICK HERE FOR SECURE DEPOSIT LINK](https://www.paypal.com/instantcommerce/checkout/8P9NUAVQM8UEN)*** *Deposit is refundable up to 90 days before the departure (less PayPal fees).* *IF you need an airfare quote,* [Click here to message Anna](https://secure.meetup.com/messages/?new_convo=true&member_id=131297062) For more information about this or any of our other international events, fill out this form: **[INTERNATIONAL MEETUPS INFO REQUEST](https://forms.gle/cQdqYw74gAYqphXX8)** To see pictures from our Kilimanjaro adventure in 2024 [CLICK HERE](https://photos.google.com/share/AF1QipPkfkUp6sEZVQ-xse1di_K19d1QVmSb5KOLeIjynRoWGv_XFLXI8wBfT61XxAHavg?key=U2tKajBuOGRiZkxBOUtTUG1GbUVRVmlDaERCeG5n) We do a monthly Q & A Zoom: Meet others attending, be social, or come and get any questions answered.
