uSwitch is located on the first floor of the ZPG building at 5 Copper Row, London, SE1 2LH, London (Click on the map for directions) What 3 words location: [https://what3words.com/puts.sudden.else](https://what3words.com/puts.sudden.else) The Clojure dojo is a collaborative way to learn Clojure/ClojureScript through practice. The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken). Example challenges for the coding dojo are listed on this website: http://www.londonclojurians.org/code-dojo/ Various past exercises have been loaded to [https://github.com/ldnclj](https://github.com/ldnclj/lisp1.5/blob/master/src/lisp1/5.clj) # Approximate schedule: 18:40 Doors open and start collecting suggestions 18.45 Pizza should have arrived 19:00 Quick intros and vote on suggestions 19:15 Break out into groups and start practising 20:45 Gather together for a quick show and tell # What should I bring? We organise into small groups, so if you have a laptop with a working Clojure environment please bring it along (there are lots of online Clojure environments, so you can just use your browser too). # How do I get in to the building? At the glass doors press the buzzer to inform the security guard you are here. Say you are here for the event on the first floor. Is there way to talk with the Clojure community? Why yes. The Clojurians Slack channel is full of friendly people who love to try and help. People based in London are often in the #clojure-uk channel. Sign up for a free account to the Clojurians Slack community via http://clojurians.net/ What is Clojure? Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

**Um was geht es dieses mal?** Dieses Mal dreht sich alles um aktuelle Herausforderungen, Best Practices und Trends rund um IT-Sicherheit. Freut euch auf praxisnahe Einblicke, spannende Diskussionen und den Austausch mit Security-Expert:innen. **So leicht können Hacker Ihr Unternehmen über öffentliche Daten angreifen - Mehmet Avci (codecentric)** Jedes Unternehmen hinterlässt einen digitalen Fußabdruck – oft unbemerkt, aber öffentlich zugänglich. Genau diese frei verfügbaren Informationen machen sich Angreifer im Rahmen von Open Source Intelligence (OSINT) zunutze, um gezielte Angriffe vorzubereiten, ohne dabei technische Schutzmechanismen direkt angreifen zu müssen. In diesem Talk wird gezeigt, wie einfach es für Angreifer ist, Unternehmen allein auf Basis öffentlich verfügbarer Daten zu analysieren und zu kompromittieren. Nach einer Einführung in die Grundlagen von OSINT und die typischen Phasen eines OSINT‑Prozesses werden verschiedene Techniken vorgestellt und eingeordnet. Dazu gehören unter anderem Subdomain‑Enumeration, Google Dorking, die Auswertung von Unternehmensinformationen, Social‑Media‑Analysen, das Sammeln von E‑Mail‑Adressen sowie die Nutzung von Datenlecks und Breach‑Daten. Anhand praxisnaher Beispiele aus realen Szenarien wird verdeutlicht, wofür diese Techniken eingesetzt werden und wie Angreifer die gewonnenen Informationen miteinander kombinieren, um detaillierte Profile von Organisationen, Infrastrukturen und Mitarbeitenden zu erstellen. Der Vortrag schärft das Bewusstsein dafür, wie aus scheinbar harmlosen Einzeldaten ein ernstzunehmendes Sicherheitsrisiko entstehen kann – und warum OSINT ein zentraler Bestandteil moderner Angriffe ist. **This is fine - until it's not - Christian Uhsat (codecentric)** Was passiert, wenn was passiert? Erfahrungsberichte aus Digitaler Forensik und Incident Response im Kampf gegen Cybercrime, Ransomware und den allgemeinen Wahnsinn. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel ](https://www.youtube.com/@codecentricAG)der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

**Discussion overview:** Whether in social life, dating, or at work, we all react differently when someone gets too close (or too far), physically or emotionally. But how much is too much? When does it become creepy? Should certain topics always be avoided? The answer is often personal and subjective, but also influenced by people's different cultures. Why do some cultures touch and hug everyone they meet - is it romantic, or just friendly? Why do some overshare or ask about every little detail in life? And if someone asks for space, is it the end, or just going too fast? In a multicultural city like London where so many different social conventions and scripts meet, understanding the different signals and needs for space and boundaries can help us avoid misunderstandings and interact at the right rhythm. *Join us for a relaxed group conversation where we explore the real life, the grey areas, and how our different cultures and backgrounds shape our views about key topics.* *Expect real talk, no judgment, and a chance to learn how others see it.* **\*Come for the discussion, stay for the friendships. Our weekly discussion series brings together thoughtful people for honest conversations on relationships, life, and society - with warm social vibes before and after.\*** **WHAT TO EXPECT:** * Good vibes only: we chat big topics in a chill, respectful way. No arguing - just open-minded exchange. * We warm up with casual socializing (come solo or with friends!) * The topic starts around 7:45/8pm, wraps around 9:30. * 🍕 There's pizza, drinks, milkshakes and snacks available at the bar (incl plant-based options) * And most people stay until late for drinks and mingling! **DISCUSSION FORMAT:** **\- Our group conversations are open and flexible\! There is a very soft guided flow to ensure we focus on the key questions\, and to ensure that everyone gets a balanced opportunity to speak\.** \- We rotate groups intentionally during the discussion so everyone gets to meet a wider mix of people and perspectives\. \- After the structured part\, you’re free to mix and mingle with anyone\. **Here's a typical discussion structure, but we may adjust this depending on the turnout:** \- Introductions and initial thoughts *(\~5 mins).* \- Group breakouts per question *(\~20 mins x 3).* \- Final round of opinions *(\~10 mins)*. \- Mix and mingle\, make new friends\, get drinks etc *(\~until late)* **Rules & etiquette:** 1\. Debate the topic\, not the participants \- no personal attacks please\. 2\. No phones\, no interrupting\, no bystanding\. 3\. Always follow the moderator/host instructions and guidelines\. **WHAT IS WORLD CITIZENS?** We're one of London's longest-running and largest communities. Since 2012 we run socials, cultural activities and stimulating discussions to foster meaningful exchange and learning among London's global professionals. They are inspired by MUN (Model United Nations) and salon discussions and offer a more relaxed and social evening version. **LOCATION DETAILS** What: Discussion session followed by social/networking When: Tuesday, 7:30pm until late.

Look at this as a Great Escape warm up if you want, it's a three-band bill made up of guitar acts where at least two of them are decent. And it's free, at the Sebright Arms, one of the more reliable gig pubs in East London. What's not to like? So, what about the bands? Clothesline From Hell is pure early 2000’s Reading Festival stuff – a bit of emo, a bit of grunge and some trip hop-like beats attached. It shouldn’t really work but there’s an air of mystery about them and the songs are good enough that it does. Cool early 2000's band name too, which always helps. Truest Sound: https://www.youtube.com/watch?v=Fzd1KYtQ3qs Curiosity Shop play trad folk-sounding stuff. Not as keen about this lot and they have very little online presence (seriously lads, YouTube shorts only?) but they can be a quieter palate cleanser between the noisier bands or an opportunity to grab a drink. A snatch of One For the Shirt Pocket: https://www.youtube.com/shorts/yu8wO9j-xFA Really Good Time play loud, bouncy, punky rock. Apparently they have a rep as a really good live band – not sure if they are but they look and seem like a band that probably moves around a bit onstage. Scott Carson: https://www.youtube.com/watch?v=jEGlBCGjDOY Tickets are free and available [here](https://dice.fm/event/g5mx55-clothesline-from-hell-curiosity-shop-really-good-time-12th-may-sebright-arms-london-tickets?pid=90cbdc62&_branch_match_id=1574931611192544186&utm_medium=partners_api&_branch_referrer=H4sIAAAAAAAAA8soKSkottLXz8nMy9ZLyUxO1UvL1U8xMrAwSzIzMzZJTrYvyEyxtTRITkpJNjNSqytKTUstKsrMS49PKsovL04tsnXLBIrlVwAAGlzRhkkAAAA%3D). I would grab one just in case. Doors open at half seven so let's meet upstairs from 7pm and head down when the first band comes on.

Join us for our next Emacs London meetup held at University College London (UCL). A projector will be available, if anyone wants to give a presentation and/or if helpful to share Emacs tips, for some collaborative debugging, etc. We might head to a pub for a drink and/or a nibble afterward. Emacs users of all levels welcome! Interested in Emacs but not really a user? You're more than welcome too! **Call for presentations** Fancy talking about your favourite Emacs package? Proud of your latest Emacs Lisp hack and you want to tell everybody? Anything parenthesis-related that's bugging you? There'll be a monitor waiting for you for a short presentation!

Many governments are now pushing age verification and VPN restriction laws, lobbied by Big Tech companies, with no visible popular demand for it. Is that truly to "protect children", or is it better explained by desire to control and censor online speech, while appeasing their corporate donors? Let's discuss the future of the Internet, freedom from censorship, privacy vs. security trade-off, and other related topics. To kick off the conversation, we will look at Cory Doctorow's essay on age verification and "Online Safety Act" called ***[“Privacy preserving age verification” is bullshit](https://doctorow.medium.com/privacy-preserving-age-verification-is-bullshit-0aefd53019e0)***. *<...>politicians all over the world demanded a kind of impossible encryption: encryption that works perfectly when it’s doing something legitimate, like keeping hackers from pushing malware to your pacemaker or stealing your life’s savings or listening in on you through your phone’s microphone, but also they require that this encryption offer no protection to criminals, drug dealers, terrorists, child abusers, and other miscreants.* *This really is like water that’s not wet.*

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Caroline Morton and Katrina Petrevice. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Katrina Petrevice: Caching in Scala using Ref 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective) 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event may have a live stream** Watch this space for more details. **🗣️ Katrina Petrevice: Caching in Scala using Ref** Caching in memory is often one of the first strategies used to improve system performances. However, implementing caching in a purely functional way introduces unique challenges, specifically around state management and testability. In this talk, we will look at how to utilise functional programming principles with [Ref](https://typelevel.org/cats-effect/docs/std/ref), while maintaining clarity and composability. We will also deep dive into some common pitfalls and look into practical ways to test Ref effectively. ⭐ Katrina Petrevice ⭐ Katrina comes from a non–computer science background and was first introduced to Scala while working at JPMorgan. She credits much of her Scala knowledge to hands-on experience within her team, where she works on building and maintaining data pipelines and managing data systems. Since then, she has developed a strong interest in functional programming and now co-leads the Functional Programming Group at JPMorgan, where she helps share knowledge and foster a community around these ideas. **🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective)** I don't have a background in functional programming - and I never set out to write it. But somewhere between writing trait-based epidemiological pipelines, composing data transformations, and leaning hard on Result, enums, and pattern matching, I started hearing from others: “That's pretty functional.” In this talk, I'll explore what it means to write “functional-ish” Rust as someone solving real-world scientific problems. I'll walk through the patterns I reach for - like chaining iterators, avoiding shared state, and embracing expressive types - and reflect on which functional programming ideas emerge naturally in Rust, even if you're not trying. I'll also share how designing for epidemiologists - most of whom are used to chaining functions in Python (like Pandas) or R - has pushed me toward creating ergonomic Rust APIs with Python and R bindings. These tools aim to feel familiar to scientists while leveraging Rust's power and safety under the hood. This is a talk for functional programmers curious about Rust, and for Rustaceans wondering if they've been functional all along. No formal theory required - just real code, real use cases, and a pragmatic perspective from someone building public health tools in Rust. ⭐ Caroline Morton ⭐ Dr. Caroline Morton is a medical doctor, epidemiologist, software engineer, and PhD candidate specialising in synthetic data, epidemiology, and Rust. With 60 peer-reviewed papers and two books on software, she combines deep technical expertise with a commitment to improving scientific workflows. Caroline co-founded the first [Women in Rust](https://www.meetup.com/women-in-rust/) group, fostering diversity and encouraging more women to explore opportunities in systems programming. She leads an open-source project improving codelist management in epidemiology using Rust, creating efficient, reliable tools for health data research. Her PhD focuses on synthetic data methods for epidemiology, particularly using Rust to generate large, realistic datasets. A strong advocate for open science and reproducibility, she contributes extensively to improving software practices through publications, workshops, and open-source projects. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

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.
