Filozofování o životě a o všem ostatním pro všechny, bez vstupného a bez přihlášky: Co si přejete, s čím si lámete hlavu, co Vás nenechá spát, o čem dumáte, o čem sníte, co Vám vrtá hlavou, čeho se bojíte, na co vzpomínáte, o čem přemýšlíte? Nenechte tyto věci jen pro sebe, zkuste rozhovor s jinými lidmi. U nás nejde jen o to, si popovídat, o to taky, ale to máte i jinde. U našeho stolu se pokusíme, spolu *filozofovat*. Nejdříve se dohodneme, jaké téma budeme diskutovat, a pak se do toho pustíme, budeme přemýšlet, rozmýšlet, promýšlet a zamýšlet se, až se nám z toho bude točit hlava, přitom nám budou podporou filozofové všech věků, abychom jí neztratili, tu hlavu. Ani byste nevěřili, jak filozofie může být osvěžující…

Hola tod@s! Tenemos otra reunion este viernes en Cafedu! Sois muy bienvenidos!

Let's hike! 🥾 To a peak frequently referred to as the "Olympus of Brdy". Highlights of the hike: \- a lookout tower and view points \- the Olympus of the Brdy mountains called Plešivec \- some rocks \- a lovely day in nature Here is the approximate trail https://mapy.com/s/pojupaduco I reserve the right to adjust the trail depending on the group :-) Wear shoes good for hiking. TAKE FOOD FOR MOST OF DAY, there won't be much to get in the forest. We will buy the tickets on the spot, no need to get anything in advance, just show up. We will go by bus there, and by train back to Prague. I expect to be back at around 7pm, it all depends on our speed (no rush) The hike is not super hard, but it does involve some ascending and is over 20km, so a decent condition is required. COST: Approximately 200 Kč for tickets. As always, if you know about someone interested, feel free to take them with you. This event is free of charge, but any **contribution for organizing and to cover the subscription fees is more than welcome** (100+ CZK is recommended, but it's totally up to you how much you think the trip was worth, your financial possibilities etc.). You pay at the end of the trip. It's okay if your plans change, but please also change your status accordingly. We will meet at the Smíchov train station, OUTSIDE, IN FRONT OF THE MAIN ENTRANCE AT 9.55. I'm looking forward to seeing you all again! Jirka 🙏🤗

**The most enjoyable dance friending event on a Friday night 🌤️💃✨** This is an OPEN-AIR event! We are dancing outdoors on a soft athletic surface. Restrooms and changing areas are available at a small restaurant nearby. 🚻 The night starts at 7:00 PM with chill music, socializing, and basic footwork. If you want to level up your dancing, be there at 7! Later, we flow into casual dancing, mixing European classics (Waltz, Polka) with modern Balfolk and chill Latin vibes (Forró). ✅ **No experience needed** → Come at 7 PM to learn the basics! 👣 ✅ **No partner needed** → We rotate! Feel free to ask anyone taking a break. 👋 ✅ **No dress code** → Wear comfy sneakers or go completely barefoot. 👟 ✅ **No pressure** → As long as you can sway to the rhythm, you belong! 🌟 ✅ **Free entry** → If you love the vibe, hit us with a 5-star review 🌟 or leave a voluntary tip via QR code (suggested 200 CZK). If you love to move and want to make new friends, simply show up on Friday and let’s dance!! 💃🔥 *Tančírna (pronounced tahn-cheer-nah) comes from the Czech word "tančit" (to dance) and literally means "a place for dancing".* **Pro-tip:** Pack a water bottle to stay hydrated 💧 and a hoodie for when the sun goes down! Ordering drinks/food at the local restaurant is possible, but it breaks the flow, so we usually do it after we wrap up. 💃🔥

Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences. We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks. Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
