En definitiva, se trata de conocernos como personas para entendernos como escritores. No importa si has escrito diez novelas, cuatro cuentos o el precioso título de un poema sin versos.

Ebben az előadásban 3–4 vezető EDR működését vizsgáljuk meg technikai szinten: hogyan hookolják a rendszer DLL-eket, hogyan használnak ETW-t és miként integrálják az AMSI-t. Az előadás bemutatja a patch/bypass alapelveit is, gyakorlati példákon keresztül. Célunk egy erős technikai alap megadása azoknak, akik mélyebben szeretnének elindulni az EDR-ek elemzésének és megkerülésének világában. Előadó: Django.

*All the presentations are in Hungarian. Thanks for your understanding!* Miért rákkeltő az alkoholfogyasztás? És mi az univerzum két legnagyobb rejtélye? A márciusi Budapest Science Meetupon kiderül. **Az alkohol rákkeltő hatásának nyomában** *Szüts Dávid – HUN-REN TTK, Molekuláris Élettudományi Intézet, Genom Stabilitás Kutatócsoport* Az alkoholfogyasztás ismerten rákkeltő, de vajon miért? Kutatócsoportunk az etanol fő bomlástermékének, az acetaldehidnek a mutagenikus hatását vizsgálta sejttenyészetekben. Az általunk talált hatás enyhe, de egyértelmű: DNS-törésekre utaló genomi átrendeződéseket találtuk sejtvonalakon végzett kísérletekben, és ugyanilyen mutációk alkoholfogyasztással való asszociációját gyomorrák esetekben. Az eredmények alapján az acetaldehid DNS-töréseket előidézve okozhat olyan változásokat a testi sejtek génállományában, amelyek hozzájárulnak a tumorok kialakulásához. **Az univerzum két nagy rejtélye: a sötét energia és a Hubble-feszültség** *Raffai Péter – ELTE TTK Atomfizikai Tanszék* A fizikai kozmológia alapvetése, hogy a világegyetem nagy léptékben homogén. Einstein általános relativitáselmélete szerint egy ilyen univerzum tágul, vagyis a kozmikus távolságok -például a galaxisok között- mindenütt azonos ütemben nőnek. A növekedés mai üteme, a Hubble-állandó, a tágulástörténet kulcsparamétere - az univerzum korát is ő árulja el. A legkülönfélébb megfigyelésekhez a Lambda-CDM kozmológiai modell illeszkedik leginkább; eszerint a tágulás mintegy 5 milliárd éve lassulóból gyorsulóba váltott át, egy ismeretlen összetevő, a sötét energia hatására. A sötét energia mellett a kozmológia legégetőbb kihívásává a "Hubble-feszültség" vált: a Hubble-állandó különböző mérési módszerekkel kétféle értékűnek adódik. Vajon ez csak mérési hiba? Vagy forradalom előjele a kozmológiában? És lehet a két nagy rejtélynek közös feloldása?

**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Data Science & Machine Learning with Microsoft Fabric" Hello Everyone! Please join us for our March 12th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Data Science & Machine Learning with Microsoft Fabric **Description:** Explore Microsoft Fabric’s integrated Data Science experience across ideation, preprocessing, modeling, & deployment. Learn how to ingest and prepare data via OneLake and Lakehouse, leverage Notebooks, Data Wrangler, Spark, SynapseML, MLflow for experimentation, & operationalize predictions with batch scoring and Power BI direct integration. Also, learn to build generative AI Q&A systems using Fabric Data Agents. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

**Agenda:** * 6-6:30 pm: Networking and food/drinks * 6:30-7:15 pm: Announcements and presentation * 7:15 pm-7:30 pm: Q&A and close-out **Hacking the Stack: Using OpenSearch Dashboards as an Application Framework** Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**

This group is for anyone who wants to explore Buddhist meditation in a relaxed and supportive setting. Each session includes a short meditation, a simple teaching from Buddhist psychology, and an open discussion about how these ideas show up in everyday life. While our foundation is Buddhist practice, we love weaving in wisdom from other traditions whenever it helps us grow, find peace, and support each other. Members of our community come from many different backgrounds, and you do not need to consider yourself a Buddhist to attend. All are welcome. The session runs from 7:00 to 8:00 p.m., with doors open from 6:30 to 9:00. Come early or stay after if you’d like to enjoy some quiet reflection or casual conversation with the community. On the first Wednesday of each month, we share a potluck meal. Bring a dish if you’d like, but the most important thing you can bring is yourself. We look forward to seeing you!

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Traditional buyers transact once every 7–10 years. Investors transact 3–10 times a year.** If you want predictable income, consistent deal flow, and a long-term wealth ecosystem, you don’t need more leads—you need a better list: a database of committed investors who buy repeatedly. The Investor Goldmine teaches you how to build, grow, and activate an investor database that becomes your most valuable asset in real estate. Instead of competing for one-time transactions, you position yourself as the Agent Investor—someone who understands strategy, leverage, and wealth building. In this session, you’ll learn the proven systems to build your investor list from scratch, including: * Where to network to meet real investors already buying * A simple “one lunch a week” strategy to build relationships fast * How to use giving and social currency to become the trusted connector * How absentee owners and business owners can become your best investor pipeline * Why community accelerates database growth—even if you don’t run one You’ll also get a clear activation plan to start growing and converting your investor database immediately. Because the model is simple: Build the list. Call the list. Market to the list. And your income becomes repeatable. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
