**IMPORTANT PLEASE RSVP:** https://www.jug.ch/html/events/2026/data-streaming-security.html \*\*\* ROOM: PH Zürich, Lagerstrasse 2, 8090 Zürich, Building LAB, Room H015 AGENDA: 18:15-19:30h: Talk incl. Q/A * After the talk, you will have the opportunity to exchange ideas and network with the speaker and professional colleagues over beer and rich finger foods. **SPEAKER**: Olena Kutsenko **COMPANY**: [Confluent](https://www.confluent.io/) Data streaming is powering everything from fraud detection and real-time analytics to patient monitoring and order fulfillment. But as the role of streaming grows, so does the risk - because many streaming platforms, like Apache Kafka, aren't secure by default. In this talk, we'll take a practical look at data streaming security through the lens of Kafka, one of the most widely adopted streaming platforms in the world. We'll walk through what can go wrong - real examples of exposing 14M patient-doctor messages, or years of real-time delivery info to the internet - and what it takes to do it right. We'll cover the key pillars of securing a streaming system: encryption in transit and at rest, access control, monitoring, and key management. Along the way, we'll look at the trade-offs like disk encryption vs. end-to-end encryption, what is behind field-level and envelope encryption, and the realities of using customer-managed keys in regulated industries. We'll also explore how streaming security has evolved, how real vulnerabilities (like CVE-2019-12399) highlight the need for patching and monitoring, and what successful multi-layered security looks like in production - from financial institutions to healthcare platforms. If you're building, running, or scaling streaming systems, this talk will help you see the security blind spots and give you concrete steps to protect the data flowing through your pipelines.

Every Wednesday Kalli Craft hosts a free 2 hour competition. Join us, meet new people and enjoy Swiss Craft beer! **What is Shufl board?** Shuflboard is a game that can be played with up to 8 people. The game looks a lot like curling with the objective to get the puck as far on the board as possible without falling off. **How does the competion work?** After checking in at the bar, two teams will be created. The staff will explain the rules of the game and then it's time for competion! Around 21:00 the game will end and the winners get a free beer and ethernal glory. **About** Kalli Craft is a place where people could come and meet new friends, socialise and have a good time. All with one special thing in common: Incredible beer! At Kalli Craft you can tap your own beer. There are always 8 Swiss Craft beers on tap and the selection changes regularly. You pay per volume so you can choose to take a sip of each beer before you tap a whole glass. Next to craft beer, we also have a wide selection of sodas, wine, prosecco and alcohol free beers.

Come see the games created during Global Game Jam 2026 in Zurich! Plus, as always, meet and talk with other game developers.

Welcome to our Board and Card Game Event for all kinds of games from fun/leisure games to heavy strategy ones😊 You are welcome to join whenever you feel like it. You don't have to be there at 5pm. Come whenever it's best for you. First timer? No board or card game experience? Not to worry. We are happy to explain every game we play 😊 You are always welcome to bring your favourite games along. We collect no dues at the moment but ask attendees to at least buy a drink in the restaurant where we meet, and not to bring thier own food or drink.

The 2026 winter Olympics are in full swing now. Vicariously viewing the vigor and vitality of the the various virtuosos vying for victory is not enough. You want to compete and test your mettle in our very own hashy olympic trials. Come this Thursday to see how you face against fellow hashers in tests of dexterity, willpower, endurance and tactical acumen such as: * find the trail * table ice hockey * foot biathlon * don't lose your gloves * (drinking from the) ice luge * ski mountaineering * Yelling "On on" The trail and trials will be set and conducted by CHEESM. **Where**: Starting from the baggage lockers in the mezzanine of Zürich HB. **When:** We'll meet at 6:50 pm to start at 7:00 pm. There's a charge of CHF 5 for participating, which covers all you can drink beer/cider (and non-alcoholic alternatives) plus snacks afterwards. **All Welcome:** If you are new, curious, and want to get out of the house, stretch your legs, talk shit, enjoy a drink, and hopefully a laugh, then here's what you need to know: • We are a social running/walking group, physical fitness is not required, but a sense of humour is useful. • The aim is to find the '*Beer Stop*' at the end of the '*trail*' and have fun. • 'True Trail' is typically 4-7 km. Some will go less (especially those walking or walk/running), and some over-achieving fast runners will go further. • The '*Hare*', which changes each event (along with location), cleverly lays the trail (typically with flour marks) so that everyone reaches the end at the same time. • There is always a place to deposit your bag and sometimes a place to change. • **After Trail**, we group for \~20-40 minutes for drinks, snacks, and some fun. This '*Circle*' is typically outside, so leave something warm in your bag in winter (and bring a flashlight when it's dark). If you don't want to stand around drinking afterwards, you can head home. We occasionally all go to a restaurant afterwards. **Why bother leaving your warm & dry sofa?** If you enjoy getting outside, being around people, and doing something a bit different, you will probably enjoy hashing. Exercise is important, and this is probably the least boring way to get it. 'Hashing' and the idea of some physical activity to work up a thirst, have been around for almost 90 years and there are groups (*Hashes*) in most major cities. Its humor and 'traditions' can be explored on the internet - **or you can just come along and find out.** *See you there.* We are of many nationalities, all ages, full of misfits and idiots (at least there is no one taking themselves seriously!) and always welcome newbies 'Virgin Hashers' and visitors from other groups.

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.

**NEW LOCATION: Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: * 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. * 6:30 to 8:00 pm. Main meeting and presentation(s). Lonnie Morgan will be presenting information about the DLT Library. "The Python library `dlt` provides a powerful [REST API toolkit](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api/basic) to ingest data. Combined with our [LLM scaffolds](https://dlthub.com/workspace) and [MCP server](https://dlthub.com/docs/hub/features/mcp-server), you can build a custom connector for any of the 8k+ available sources in 10 minutes by following this guide. Building with LLMs is an iterative process. We will follow this general workflow and give practical tips for each step." See Our [Parking Map](https://docs.google.com/presentation/d/1u2A4fLNlxwLJn0KA_hKc8bnFlFHLvsHBDh-_8wzX_tk/edit?usp=sharing) We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact centralohpython@gmail.com
