**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** *[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.* *This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting*** On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence. But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans? Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food. **2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality*** Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers? Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome. **3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣** The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly. But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others. In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

Bringt gute Laune, schönes Wetter und Interesse mit. Wir treffen uns je nach Tour an unterschiedlichen Orten. Am 1. April 2018 um 15 Uhr gehts los am Eingang zur Akademie der Künste am Pariser Platz neben dem Brandenburger Tor.

**Step right up for a fortune-telling experience that's barely accurate, but definitely unforgettable.** Magdalena, the "fortune teller", combines a crystal ball, questionable predictions and a healthy dose of dark humour in a show that's as absurd as it is entertaining. Described by the 'Scotsman' (top newspaper in the UK) as 'unexpected, clever, ridiculous but great stuff, crystal ball and all', this interactive comedy has left audiences worldwide laughing and wondering what just happened. Some say it's life-changing, others call it pure nonsense-but no one escapes without a few laughs, some spirit summoning and answers you probably didn't want. **Sold out run in Edinburgh Fringe Festival 2025** Reserve your seat for just €2, and at the end of the show, you decide what it was worth (suggested contribution: €10-15). Reservations are held until 10 minutes before the show starts. This is a paid show—you just get to choose how much to pay. **Make sure to reserve your ticket [HERE](https://www.eventbrite.co.uk/e/01-accurate-english-comedy-night-tickets-1980718239574?aff=meetup)**

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

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.
