A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **TO BOOK**: It's essential that you book onto sessions via our website, using the link below; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals. [https://joinrabble.com/locations/london/](https://joinrabble.com/locations/london/) Use the code **FREEPLAY** to get your first game free! *** We play every: * Monday in Finsbury Park (19:00 - 20:00) * Tuesday in Shoreditch Park (19:00 - 20:00) * Wednesdays in Elephant & Castle (19:00-20:00) * Saturday in Southwark Park (10:30 - 11:30) * Saturday in Finsbury Park (11:00 - 12:00) * Sunday in Clapham Common (12:00 - 13:00) We hope to see you playing soon!

\*\* Please RSVP - this helps the venue plan ahead and ensure enough space is reserved for us \*\* Hey everyone! Are you a young professional in your 20s/30s looking to meet other LGBTQ+ young professionals? Then we hope to see you at the upcoming Tuesday drinks! Most people come to these drinks by themselves, and half of the people are first-timers, so these evenings are great to meet new people in London. We have tables reserved on the top floor (loft) of The Yard bar in Soho. Go into the Yard, turn left, and head upstairs. Just ask the bar for the tables reserved for the "Meetup". We usually have the tables opposite to the bar. Many have noticed that it can be difficult to meet up with the LGBTQ+ community once you leave university or come to a big new city such as London. For this reason we've decided to start organising drinks for young professionals, intended for those who love to have a drink with like-minded people after a busy day of work. Do spread the word, and bring friends, colleagues and family! Frequently Asked Questions: It's my first time and I'm coming alone, should I be nervous? No, you found the right event! Almost everyone joins these drinks alone and there are always a bunch of first timers. Just grab a drink and say hi to those around the reserved tables and you'll be absolutely fine :) I cannot make it at 7.00pm, can I come later? Yes, definitely! There will always be one of the organisers present from 7.00pm onwards, but most people just join whenever they can. There is no official 'start' so to say, and it usually stays busy till around 10pm-11pm. For first timers it can be easier to mingle if you come before 8pm, when it's not that busy yet. How often are the drinks and where are they held? We have drinks every two weeks from 7.00pm at The Yard Bar in Soho. Sometimes we organise other events such as big nights out, pub crawls and picnics. Just keep an eye on the Meetup page. Is there a dress code? Nope, not at all. Just wear whatever you want. Is there a cost? Only for whatever drinks you buy at the bar. That said, if you enjoy the Meetup, we would really welcome any cash donations to help cover our costs for running the events. However, you will never be directly asked for any money from any of our team. Are the Tuesday drinks for networking? No, the drinks are super casual, and not intended to find your new dream job. We have people from all different professional backgrounds, so it's always cool to hear what others are up to. I don't drink alcohol, can I come? Of course! Since it's on a Tuesday many take it easy, so you won't be an outlier. If you have any questions don't hesitate to pop any of our organisers a message. Looking forward to meeting you all! Xx The young LGBTQ+ professionals team Xx

We'd love you to join us at the offices of the aptly named Tenth Revolution to help us celebrate. # TENTH ANNIVERSARY CELEBRATION WITH CHRIS WEBB Chris has presented at the user group every year in May to celebrate our anniversary, and we didn't want this year to be any different. **Power BI under the bonnet**: monitoring queries and refreshes using Workspace Monitoring, Log Analytics, Profiler and DAX Studio When you're performance tuning a slow Power BI report or refresh you need to know what happens inside the engine, and the good news is that the Power BI engine can give you all kinds of detailed information on its internals. But how do you get access to this? How can you understand it? In this session you'll find out: how you can get (almost) the same information on internals from Workspace Monitoring, Log Analytics, SQL Server Profiler and DAX Studio and when to use which; which engine events are relevant to queries and which ones are relevant to refreshes; and how you can interpret this information for tuning. **Agenda** 18:30 - Welcome, drinks, pizza & networking 19:00 - Main Session 20:00 - Help us celebrate at a local pub (details to be confirmed on the night) **Venue** Tenth Revolution offices in London. Aldgate House, 33 Aldgate High St, London EC3N 1DL Please provide your first and last name when registering for the event, as this is provided to building security to allow you entrance into the venue.

There are many resources available for guidance on how to write code that is efficient and results in more sustainable software applications, but applying these at scale can be challenging, and often isn’t a priority for busy teams. GitHub have recently released Agentic Workflows, a way of specifying automation tasks in human-readable format to be performed by an AI agent as part of a GitHub Actions workflow. In this talk, Max Mizzi from GitHub's Sustainability team gives an overview of Agentic Workflows, and will demonstrate how they can be used to improve software efficiency through both structured green software rules and autonomous performance engineering. He'll finish by walking through a real-world use-case showing how the technology helped to dramatically reduce the energy consumption - and carbon footprint - of a major website. Come along if you want to learn more about using AI to improve the energy efficiency of your software. Check out the Green Software Brighton [website](https://greensoftwarebrighton.co.uk/) for links to previous talks. Arrive from 18:00 for pizza and drinks. Event will start at 18:30. We always head for a drink and a chat locally afterwards too. --- ***Thank you to Runway East for use of their space to host our events and to Silicon Brighton and the Green Software Foundation for supporting us.***
