**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

Hello everyone, Due to popular request (and some other reasons, like venue availability and available organiser capacity), we’re happy to announce that the Rust Berlin talk meetups are back. This is the classic meetup format: let’s meet in the evening see 2 speakers and then spend some idle time chatting about what we heard. The first speaker for the first edition will be our co-organiser Florian Gilcher, speaking about “Unsafe demystified”, a gentle introduction into handing unsafe code properly. Soares Chen will talk about the current revision of Context Generic, their framework for context generic programming: https://contextgeneric.dev We are also available for new talks, in particular of people who never gave a public talk. We’re happy to be your first talk location. The new meetup is currently organised by Florian and Liran, who is a new co-organiser at Rust Berlin. JetBrains was so kind to offer us their office location as a default meeting point. Thank you! We’re looking forward to getting the ball rolling again! See you all on April 1st! **Line-Up** Unsafe demystified by Florian Gilcher This is a beginner- to mid-level talk that explains the basics of unsafe and how to program it. Instead of going fully into it all details of unsafe, this talk teaches you easy to digest mental frameworks to use when approaching your next unsafe code block. Supercharge Rust functions with CGP implicit arguments by Soares Chen I will give a short overview of the new implicit arguments feature for Context-Generic Programming (CGP), which enables structural typing in Rust. Some short example demos will be presented, followed by some explanation of how the feature works. **Speaker Bios** Florian Gilcher Florian Gilcher used to be part of the Rust team at several positions and served as a member of the Rust Foundation board. He is also a co-founder of the Rust Berlin meetup. Today, he’s training Rust at Ferrous Systems, a company he co-founded. Soares Chen Soares is a Rust programmer with a strong interest in functional programming, type theory, and programming language design. He is the creator of Context-Generic Programming and currently works as a Rust engineer at Tensordyne.

Mit dem Titel "Philosophie 2.0" wird nicht zu viel versprochen. Nicht alles was mit 'Philosophie' bezeichnet wird, hat damit auch zu tun. Das gilt allgemein. Wörter werden zu oft nicht präzise gebraucht, aber wenn man alles mit beliebigen Wörtern bezeichnen würde, könnte man nichts mehr genau verstehen, könnte nichts mehr genau begreifen. Also blieben die Irrtümer bestehen. Das hätte mit Philosophie aber definitiv nichts mehr zu tun. Was also ist das Gegenteil belanglos-vieldeutigen Wörterverdehens mit hochassoziativen Sprüngen bei denen allerlei übersehen wird und ergo das Wesentliche nicht mehr als solches klar erkannt werden kann? Maximal exakte Begriffsklärung. Und das geht! Das geht über einen systematischen Aufbau aller Kategorien - gestützt über einen Algorithmus, welcher Kategorienfehler automatisch vermeidet und mithilft, das Ganze im Blick zu behalten. Dass dies für uns Personen gar nicht so einfach ist, sieht man daran, dass jede Person (auch Du) irgendwann irgendwelchen Irrtümern aufgesessen ist. Jede Person, die sich also für irgendetwas ernsthaft (nicht wegen blanglosem Amüsement, oder wegen ideologischer Rechthaberei) interessiert und ergo dafür offen ist seine Auffassungen weiterzuentwickeln, ist bei dieser Veranstaltung goldrichtig. Ablauf: Bei unserer Diskussion geht es dabei nicht um irgendein festes Thema, sondern jeder schreibt ein Wort in seinem Interessengebiet auf einen Zettel und wir ziehen diese paarweise für je eine Runde. Die beiden Wörter haben gemeinsame Kategorien, aber es gibt auch Unterschiede. Wer diese nicht alle kennt, kann nicht behaupten, dass er tatsächlich begriffen hat, wovon er meint, dass es ihn interessiere; dass er definitiv wüsste wovon er spricht. Dieses Problem hatte schon Sokrates erkannt. Nur haben wir jetzt einen Algorithmus, welcher zu absoluter Genauigkeit verhilft um diese Irrtümer loszuwerden. Daher 'Philosophie 2.0'. Siehe dem Bild oben werfen wir die Bedeutung (die Menge aller Kategorien einer Begrifflichkeit) per Beamer an die Wand. Wir sind nicht in der Schule, d.h. es gibt keinen Zeitdruck, keine Noten, keinen Wettbewerb und keine Profilierungsmotive, sondern jeder hat alle Zeit der Welt um über die schematisch dargestellte Bedeutung nachzudenken - und diese zu hinterfragen. Die grafisch dargestellten Bedeutungen des Algorithmus sind nicht perfekt. Es geht nicht darum irgendetwas zu akzeptieren, sondern andersherum: die Bedeutung anzugreifen und zu verbessern. Jeder kann sie ändern! Die Diskussion ist also eröffnet. Jeder muss Gründe angeben. "Kann ein Walfisch ein Wellensittich sein?" \~> Natürlich nicht, denn Säugetiere sind keine Vögel. "Kann ein Fenster ein Getränk sein?" \~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten. "Kann eine Demokratie eine Republik sein?" "Kann eine Vermutung eine Meinung sein?" "Ist etwas zu begreifen das Selbe wie etwas zu verstehen?" Nichts regt dermaßen zum nachdenken an wie die Bedeutung der Begrifflichkeiten algorithmisch stabilisiert zu systematisieren. Und wenn wir uns nicht einig werden? Die Diskussion läuft auch nach der Veranstaltung weiter. Jeder kann online von zuhause die Diskussion fortführen - mit dem selben mitdenkenden Algorithmus. Man könnte sagen, es sei ein neues Gesellschaftsspiel - ohne Wettkampf, sondern in kollektiver Bereicherung an Klarheit, von der alle gigantisch profitieren, obschon jeder nur einen sehr kleinen Teil beiträgt. Das "Spiel" funktioniert auch mehrsprachig, denn der platonische Raum der Begrifflichkeiten ist der eindeutige Raum, auf den das Vokabular einer Sprache nur referiert. Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren. Bring deinen Laptop mit, dann wird es einfacher... Dieses Spiel macht klug: Schach trainiert zwar das Konzentrationsvermögen, hat aber mit der Wirklichkeit nichts zu tun. Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden. Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger. Mach mit!

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
