Come hang out with fellow Apple platform developers and enthusiasts for an informal evening of tech talk, coffee, and good company. No agenda, no slides — just a relaxed get-together at a Copenhagen café where we geek out about Swift, iOS, visionOS, and whatever else is keeping us busy lately. Whether you're deep in SwiftUI architecture, experimenting with spatial computing, or just curious about what's happening in the Apple ecosystem, you're welcome here. Bring your questions, your opinions, and ideally a laptop if you want to show something off. See you there.

https://www.facebook.com/korsgadesprogcafe/ Come and join our cosy language cafe. We recommend that you already speak some Danish (maybe around module 3 on sprogskole) so you can join and understand the conversation. We are mostly two Danes joining, so we can make two groups: beginners and more advanced. We are having conversations while drinking tea. If you have an exam coming up, we can speak about your exam subjects some of the time. Small donations (10-20 kroner) are appreciated, to support the rent of the place. You find us in the basement of Korsgade 19. It is a door to the right of the main entrance.

Welcome to this CopenhagenR spring get-together, which will be half a relaxed presentation on useful but unorthodox applications of R, and half an opportunity to connect and chat with fellow R users over coffee and cake, or a beer! **When?** Thursday, 12 March 2026 * **17:30** – Doors open * **18:00** – *Useful applications of R*, presentation by R.M., begins * **18:30** – Connect and chat with fellow R users. There will be coffee, beer, cake, and snacks * **20:00** – No more cake **Where?** PROSA København, room PASCAL Vester Farimagsgade 37A 1606 København **What?** Join us for a CopenhagenR meetup, whether you're new to R or a seasoned pro! This CopenhagenR spring get-together includes a presentation on *Useful applications of R* by **R.M.** **Presentation: Useful applications of R** With R jobs being so difficult to obtain and so poorly compensated, I mostly apply R to the much more useful pursuit of making my life pleasant and easy. I present some short, practical uses of R, such as studying patterns in neti pot usage so I can breathe more easily, understanding my employer-provided private health insurance plan so I can figure out how much of a scam it is, and correcting predictably erroneous payslips so I can pay my taxes.

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at our Copenhagen Shut Up & Write! sessions. Be it a book, blog, script, essay, dissertation, résumé, melody, poem, or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: - 15 minutes of hellos and getting settled; maybe some quick intros. - Then, the timer starts! : writing for 1 hour. - After the hour is up... chat / take off / keep writing, if you're on a roll. OPTIONAL SOCIALIZING happens once the hour of writing is complete. Writing can be very solitary... connecting (and sometimes even commiserating) with other writers is a cool thing. It's best to be on time, but BEING LATE IS ALSO OKAY: just show up and get settled, then check in with us after the session. (We’ll be the ones with the small Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons.

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.
