The world needs leaders. Leaders head families, coach teams, run businesses, and mentor others. These leaders must not only accomplish but must also communicate. By regularly giving speeches, gaining feedback, leading teams, and guiding others to achieve their goals in a supportive atmosphere, leaders emerge from the Toastmasters program. Every Toastmaster's journey begins with a single speech. During their journey, they learn to tell their stories. They listen and answer. They plan and lead. They give feedback—and accept it. Through our community of learners, they find their path to leadership.

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?

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

The Unix philosophy emphasizes simplicity, modularity, and the idea that programs should do one thing well and work together. However, CLI programs are primarily used by humans. Programs that you actually enjoy using can achieve both of these aims of composability and human-centeredness. This talk explores what makes CLIs great: fast, trusted, and delightful. Through real-world examples from modern tools like uv, cargo, ripgrep, and GitHub CLI, you'll learn the design patterns that separate good CLIs from great ones. Whether you're building package managers, creating developer tools, or just curious why modern CLIs feel so much better, you'll leave with a practical checklist of techniques to apply to any CLI tool you build. **Agenda:** 7:00pm - Opening announcements 7:10pm - Opening Topic - Build an AI-powered, Sassy Speaking Plant 7:25pm - Main Topic - Designing Delightful CLIs with Python 7:50pm - Q&A
