*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?

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.

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.
