Short break
From 19:00: hands-on demonstration on how to use the released framework

Twenty years after the launch of the Netflix Prize (NP), we are revisiting one of the most influential machine learning competitions of all time.
Members of the original Gravity team, which also led The Ensemble team (which finished tied at the top of the leaderboard), recently revisited the NP task: not by reopening the old codebase, but by rebuilding the approach using today’s hardware, software infrastructure, deep learning frameworks, published knowledge, and AI-assisted coding tools.
The result was both exciting and humbling: even after two decades of progress, the Netflix Prize remains a remarkably hard benchmark. Our invited paper, “Netflix Prize revisited: a hard problem even after 20 years,” has been accepted to the RecSysChallenge workshop at RecSys 2026, and we have released the revival code base publicly:
https://github.com/gtakacs/netflix_prize
About one week before the workshop in Minnesota on October 2, we are organizing a hybrid meetup in Budapest and online to bring together people interested in recommender systems, machine learning competitions, deep learning, and AI-assisted coding.
Our goal is to invite the community to work on this famous task again.
We will discuss what made the original Netflix Prize special, what we learned from revisiting it with modern tools, why the task is still difficult, where deep learning helped or did not help, and how AI coding assistants performed in a real, metric-driven machine learning project.
You can join us in person or online.
Whether you’re an AI expert, data scientist, Kaggle and ML competition enthusiasts, recommender-systems practitioners, developer, or simply curious about what today’s technology can do, come along and find out with us:
Netflix Prize: Reloaded.

And of course, there’ll be food and drinks too! Stick around after the talks for some food, drinks, and informal conversations with fellow AI enthusiasts.
Whether you want to contribute code, try a new model, revisit an old idea, discuss recommender-system methodology, or simply join the conversation around a landmark ML challenge, you are warmly invited.

Let’s see what the community can do with the Netflix Prize, 20 years later.

A Jelszótöréses Hackersuli

Budapest, 🇭đŸ‡ș Hungary

A Hackersuli Meetup 2026. szeptemberi kiadĂĄsĂĄban IT biztonsĂĄgi tĂ©mĂĄval foglalkozunk: arrĂłl lesz szĂł, hogy mit jelent egy erƑs jelszĂł, Ă©s milyen mĂłdon lehet jelszavakat feltörni egy tĂĄmadĂĄs rĂ©szekĂ©nt.

Hogyan törnek fel jelszavakat offline környezetben, Ă©s mitƑl lesz egy jelszĂł valĂłban biztonsĂĄgos? Az elƑadĂĄs az alapoktĂłl indulva mutatja be a jelszĂłhash-elĂ©s mƱködĂ©sĂ©t, a saltok, pepper-ek Ă©s KDF-ek szerepĂ©t, majd bemutatja a gyakorlatban hasznĂĄlt password cracking technikĂĄkat a szĂłtĂĄras Ă©s szabĂĄlyalapĂș tĂĄmadĂĄsoktĂłl egĂ©szen a haladĂłbb mĂłdszerekig. SzĂł lesz többek között az Argon2, Scrypt, Bcrypt Ă©s PBKDF2 mƱködĂ©sĂ©rƑl, valamint arrĂłl is, hogy a kĂŒlönbözƑ jelszĂłhĂĄzirendek Ă©s hash-algoritmusok a gyakorlatban mennyire kĂ©pesek ellenĂĄllni a tĂĄmadĂĄsoknak.
TermĂ©szetesen a cĂ©l nem csupĂĄn az, hogy megtanuljuk, hogyan törhetƑ fel egy jelszĂł, hanem hogy megĂ©rtsĂŒk, milyen hibĂĄk teszik lehetƑvĂ© ezeket a tĂĄmadĂĄsokat, Ă©s hogyan Ă©pĂ­thetĂŒnk ezekkel szemben valĂłban ellenĂĄllĂł vĂ©delmet jelszavakkal Ă©s jelszavak nĂ©lkĂŒl is. Az elƑadĂĄs vĂ©gĂ©re pedig talĂĄn mindenki mĂĄskĂ©pp fog tekinteni arra, hogy mit is jelent valĂłjĂĄban egy „erƑs jelszó”.

DevBP #17: Rebuilt & Refactored

Budapest, 🇭đŸ‡ș Hungary

In the upcoming DevBP meetup, we will venture into the world of core architecture, exploring the craft of outgrowing legacy abstractions - from replacing fragile 3D algorithms with clean spatial pipelines, to evolving early Big Data setups into modern, Iceberg-powered lakehouses.

=== === === ===

A Story of a New Support Algorithm - Dmitri Megretski [Formlabs]

When 3D printing complex models, temporary supports are required to hold up overhanging geometry. Formlabs software relied on four conflicting algorithms to place these supports, causing slow performance and unpredictable results. This talk covers how Formlabs rebuilt the system into a predictable two-stage pipeline: first mapping out where a model needs structural help, then running an optimized search algorithm to place supports cleanly. Learn how the team eliminated geometric precision errors by evolving their internal data representation from basic pixel grids to sparse 3D voxels.

=== === === ===

Modern Big Data with Apache Iceberg - Attila Turoczy [Cloudera]

Early Big Data architectures struggle with modern engineering demands like schema evolution, row-level updates, and transactional consistency. This talk traces the shift from traditional Hadoop setups to modern lakehouses, exploring how open table formats like Apache Iceberg bring standard database reliability to cloud-scale data analytics.

=== === === ===

This English-language event will be held at the Formlabs Budapest office, where we'll provide snacks and drinks to fuel conversations.

Arrival is from 17:30, the presentations start at 18:00.

You can also find the recordings of previous events on the @DevBPMeetup YouTube channel.

SQL-alapok PythonbĂłl, DuckDB-vel

Budapest, 🇭đŸ‡ș Hungary

💜 Csak nƑknek szĂłlĂł PyLadies esemĂ©ny! 💜

Sziasztok PyLadiek!

Dolgozol mĂĄr Pythonnal, de az SQL mĂ©g mindig misztikusnak tƱnik? Gyere el, Ă©s fedezd fel, hogyan tudsz nĂ©hĂĄny jĂłl megĂ­rt SQL-lekĂ©rdezĂ©ssel pillanatok alatt adatokat kinyerni Ă©s feldolgozni – közvetlenĂŒl PythonbĂłl!

A relĂĄciĂłs adatbĂĄzisok strukturĂĄlt, egymĂĄssal kapcsolatban ĂĄllĂł tĂĄblĂĄkban tĂĄroljĂĄk az adatokat. Az SQL segĂ­tsĂ©gĂ©vel ezekbƑl pontosan azt vĂĄlaszthatjuk ki, amire szĂŒksĂ©gĂŒnk van: szƱrhetĂŒnk, rendezhetĂŒnk, szĂĄmĂ­tĂĄsokat vĂ©gezhetĂŒnk, Ă©s több tĂĄbla tartalmĂĄt is összekapcsolhatjuk.
A tĂ©ma kĂŒlönösen hasznossĂĄ vĂĄlik, amikor a lekĂ©rdezĂ©sek eredmĂ©nyĂ©t Pythonban szeretnĂ©nk tovĂĄbb feldolgozni. Az elƑadĂĄson ezĂ©rt az SQL alapjai mellett azt is megnĂ©zzĂŒk, hogyan futtathatunk lekĂ©rdezĂ©seket közvetlenĂŒl PythonbĂłl, a DuckDB segĂ­tsĂ©gĂ©vel.

A fƑbb tĂ©mĂĄk:
- adatok lekérdezése, szƱrése és rendezése a `SELECT`, `WHERE`, `ORDER BY` és `LIMIT` zåradékokkal;
- szöveges Ă©s dĂĄtumtĂ­pusĂș adatok kezelĂ©se, egyszerƱ mƱveletek Ă©s tĂ­puskonverziĂłk;
- több tĂĄbla összekapcsolĂĄsa kĂŒlönbözƑ `JOIN`-okkal;
- lekérdezések eredményeinek kombinålåsa a `UNION`, `UNION ALL`, `INTERSECT` és `EXCEPT` halmazmƱveletekkel;
- SQL-lekérdezések futtatåsa Pythonból relåciós adatbåzisok tåblåin, valamint CSV-, JSON-, Parquet- és Avro-fåjlokon;
- a lekérdezések eredményeinek tovåbbi feldolgozåsa Pythonban, példåul pandas DataFrame-ekben.

Az elƑadĂĄs vĂ©gĂ©re kĂ©pes leszel alapvetƑ SQL-lekĂ©rdezĂ©seket összeĂĄllĂ­tani, több adatforrĂĄst összekapcsolni, Ă©s az eredmĂ©nyeket Pythonban tovĂĄbb feldolgozni.

Omnigent: Stop Babysitting Your Coding Agents

đŸŽ€ Oleksandra Bovkun – Senior Developer Advocate, Databricks

Working with multiple coding agents often means repeatedly providing context, switching between tools, and keeping track of what each agent has already tried. Omnigent takes a different approach by bringing tools such as Claude Code, Codex, Cursor, and others into a single workflow.

Oleksandra will show how Omnigent works in practice, including how agents can communicate and debate with each other, how usage and approval policies can be managed, and how to set up the workflow effectively. Expect a live demo, lessons learned, and practical tips for getting the most out of Omnigent.

AI Opt-Out Mechanics & Self-Service HPC

Budapest, 🇭đŸ‡ș Hungary

Join us for a night of cloud guardrails and supercomputing at scale. We’re unpacking the fine print and resolution mechanics of AWS’s 31-service AI Opt-Out scope, paired with a post-mortem-heavy deep dive into self-service HPC—covering the multi-node MPI failures, mount races, and run-away costs that only happen on real production setups.
Pizza and beer included! 🍕đŸș

Agenda
18:00 - Arrival
18:15 - One Policy, Thirty Services: What Changed in AWS's AI Opt-Out Scope
18:50 - Building a Self-Service HPC Platform on AWS
19:25 - Networking, Pizza, Drinks

One Policy, Thirty Services: What Changed in AWS's AI Opt-Out Scope
Nico Herzhauser
In 2025, the AI services opt-out policy covered a handful of AI services. Today the official list counts 31 — CloudWatch, GuardDuty, Security Hub, Glue, DMS, and more. This is a Level 300/400 walk through one AWS Organizations policy most accounts never set: how it resolves, why it is not an SCP, what happens to your data with and without it, and where it silently does nothing. You leave with a checklist, a verification script, and a clear view of the edge cases the policy never reaches.

Building a Self-Service HPC Platform on AWS
IstvĂĄn SzukĂĄcs
HPC in the cloud promises elastic supercomputing on demand, but the gap between "a cluster launched" and "a cluster that actually runs your job" is where the hard lessons live. This session walks through building a self-service HPC platform on AWS — ParallelCluster/PCS, Graviton compute, Lustre scratch, and EFA networking, provisioned and torn down on demand with full cost controls. Then we deconstruct the failures that only surface on real infrastructure: a security-group rule that silently broke every multi-node MPI job over EFA, nodes accepting work before their filesystems mounted, and clusters that billed forever because an expiry date was written but never read. We share how each was root-caused live, the guardrails that now prevent them, and the Graviton price-performance trade-offs that make the whole thing worth it.

BeerUP AI Edition

Budapest, 🇭đŸ‡ș Hungary

A mestersĂ©ges intelligencia ma mĂĄr a mindennapi Ă©les kĂłd rĂ©sze. A valĂłdi kĂ©rdĂ©s az, hogyan Ă©pĂ­thetjĂŒk be a gyakorlatba a fejlesztĂ©si folyamatokba Ă©s a nagyvĂĄllalati mƱködĂ©sbe Ășgy, hogy az tĂ©nyleges Ă©rtĂ©ket teremtsen. A BeerUP AI Edition-ön a legizgalmasabb AI-trendeket, gyakorlati tapasztalatokat Ă©s a jövƑt formĂĄlĂł megoldĂĄsokat jĂĄrjuk körbe.

Az est sorĂĄn tapasztalt szakemberek osztjĂĄk meg a bevĂĄlt gyakorlatokat, a leggyakoribb buktatĂłkat Ă©s a jövƑt formĂĄlĂł megoldĂĄsokat. Szakmailag tartalmas elƑadĂĄsokkal Ă©s kötetlen networkinggel vĂĄrunk, ahol a szĂŒnetekben Ă©s az elƑadĂĄsok utĂĄn kĂ©zmƱves sörök mellett beszĂ©lgethettek tovĂĄbb a sajĂĄt tapasztalataitokrĂłl Ă©s az elƑadĂĄson hallottakrĂłl.

1. elƑadás
Salga Péter - Dyntell Software
A jelenlegi AI megoldotta a nyelvfeldolgozĂĄs problĂ©mĂĄjĂĄt, de sokak szerint ez mĂ©g nem jelenti azt, hogy valĂłban intelligens. Az elƑadĂĄsban PĂ©ter bemutatja, hogy a jelenlegi technolĂłgia milyen meglepƑ helyeken tud segĂ­teni a vĂĄllalatoknak, ugyanakkor milyen messze vagyunk mĂ©g attĂłl, hogy mindent megoldjon, a következƑ kĂ©rdĂ©sek segĂ­tsĂ©gĂ©vel:
- Milyen feladatokat lehet megoldani ma a mesterséges intelligencia segítségével?
- Mik a jelenlegi AI hatĂĄrai?
- Miért fogyaszt nagyon sok energiåt?
- És miĂ©rt nincsenek mĂ©g a konyhĂĄnkban robotok, akik megfƑzik nekĂŒnk a minestrone levest?
- Mikorra vĂĄrhatĂł a következƑ AI robbanĂĄs?

2. elƑadás
Ferenczi Marcell - HexaIO Kft.
Az AI ma az egyik legtöbbet emlegetett tĂ©ma, de mire jĂł valĂłjĂĄban a vĂĄllalati mindennapokban? Ez az elƑadĂĄs gyakorlati körkĂ©pet ad a legĂ­gĂ©retesebb AI use-case-ekrƑl: hogyan segĂ­thet egy AI e-mail-ĂŒgynök a beĂ©rkezƑ levelek kezelĂ©sĂ©ben emberi jĂłvĂĄhagyĂĄssal, hogyan vĂĄlhat a dokumentum-halmazbĂłl strukturĂĄlt, kereshetƑ informĂĄciĂł, Ă©s hol nyithat Ășj utat a hangalapĂș vezĂ©rlĂ©s. A hype helyett a hasznĂĄlhatĂł irĂĄnyokra fĂłkuszĂĄlunk: mire Ă©rdemes figyelni egy bevezetĂ©snĂ©l, milyen szerepe van az emberi kontrollnak Ă©s a megfelelƑsĂ©gnek, Ă©s hogyan lehet egy ötletbƑl lĂ©pĂ©srƑl lĂ©pĂ©sre kiprĂłbĂĄlhatĂł megoldĂĄs.

3. elƑadás
Dunai Zsolt - One Identity
Mi törtĂ©nik, amikor egy AI agent mĂĄr nem csupĂĄn javaslatokat tesz a tesztelĂ©shez, hanem a tesztelĂ©si folyamat aktĂ­v rĂ©sztvevƑjĂ©vĂ© vĂĄlik?
Az elƑadĂĄs gyakorlati tapasztalatokon keresztĂŒl mutatja be, hogyan vĂĄltozik meg a funkcionĂĄlis tesztelĂ©s, amikor az AI beĂ©pĂŒl a tesztelƑ mindennapi munkĂĄjĂĄba. Hol jelent valĂłdi segĂ­tsĂ©get Ă©s idƑmegtakarĂ­tĂĄst? Milyen feladatokat lehet rĂĄbĂ­zni, Ă©s hol marad tovĂĄbbra is nĂ©lkĂŒlözhetetlen az emberi kontroll?
A cĂ©l nem csupĂĄn az AI lehetƑsĂ©geinek bemutatĂĄsa, hanem annak körbejĂĄrĂĄsa, hogyan alakĂ­tja ĂĄt mindez azt, amit ma egy funkciĂł tesztelĂ©se alatt Ă©rtĂŒnk.
