London AI Cost Hack #1: Lowest Cost Wins

Spend an evening making an AI workflow as cheap as possible with engineers, founders, investors, and whoever else is interested in cutting their AI costs. Pizza included, £100 prize for the winner with the cheapest workflow. [Merge](https://merge.dev) is providing credits and swag for Merge Gateway, their product for LLM routing and cutting AI costs. The venue is All Saints, a church near King's Cross station: [https://www.kingshouse.org.uk/allsaints](https://www.kingshouse.org.uk/allsaints) Rough schedule: * 5:30 PM: Doors open, pizza and setup * 6:00 PM: Kickoff, challenge reveal and hacking * 8:00 PM: Submissions, scoring and demos * 8:40 PM: Winners and wrap-up; leave by 9:00 PM We’ll give you a description of an software engineering workflow, starter code, an eval set. Use whatever works to run the workflow and make it cheaper while passing the evals. Try [Merge](https://merge.dev) Gateway and see how cheap you can get! Push to a public git repo and I'll run the hidden eval set. Out of the solutions that pass, the cheapest one wins. The prize is £100 and a (very) firm handshake from a partner at a venture capital fund. Example workflow: an AI code reviewer that reads pull requests, checks for bugs and security issues, decides how risky it is, and writes a review. The baseline sends the full diff to a large model every time, including for typo fixes and dependency bumps. How much of that can you replace with smaller models, routing, rules, or local inference without making the reviewer useless? The actual challenge will be similar but a bit harder. Bring a laptop and come either solo or with a team. The venue is nut-free because some staff have serious allergies. Please don’t bring anything containing nuts. Thanks.

Bridge evening - Online event

Backgammon Social Drinks n Dinner at Civil Service Club, Great Scotland Yard

Venue: Civil Service Club Date/Time: Sunday 26 July 3-8pm and possibly beyond! First timers - please kindly read below about bringing your board, meetup fee, purchasing drinks and food, etiquette etc Please RSVP - CSC requires names of guests Intro Dear Backgammon Lovers, Given the beautiful weather and mens' Wimbledon tennis final, we had a lovely turnout of 14 backgammoners yesterday. We'll be returning next to the Civil Service Club that is moments from Trafalgar Square. Social & Fun Backgammon at the CSC Whether you're a seasoned backgammoner or a newbie looking to learn this fabulous game that is thousands of years old, our social event is open to all. This is the perfect opportunity to sharpen your game, and share a laugh (or a lucky double six!) over backgammon. Add in a drink, maybe dinner, and you’ve got the recipe for a fun and relaxed evening. Venue Food and Drink Just a little reminder that when we use the Civil Service Club, we’re asked to buy at least one drink whilst we’re there, and hopefully food too. The Club has a nice range of food and snacks on offer, all at good prices, so it’s a great chance to relax and make the most of the day. About our backgammon social group Our group has been running for nearly 11 years since June 2015 and we have held nearly 500 official backgammon meetings - along with a further 300 off-grid (non meetups) since then. We are the largest backgammon group in the UK with nearly 2,500 backgammoners as members. What makes our group special are its members and the warmth, humour and friendliness whilst playing this splendid social game over a few drinks... usually fortnightly, and on a Sunday. We have about 30-odd regular members who play socially and we very much welcome new players too - so do come along. Dinner Time and Drinks and Food In between the rounds of backgammon many of us sit for a meal around 6pm, but you can order drinks and food whenever you like. RSVP Please RSVP asap - Often I need to provide the Club with an indication of numbers. Bring your own Backgammon Board - no problem if initially you don't have one. Love seeing the different styles and size of boards - my boards have somehow gotten larger over the years. Please bring your own backgammon board and should you not have one please let us know in advance via the Meetup message board so that others can make the effort to bring theirs. Meetup Fee I will ask for £4 as the meetup fees etc have increased substantially over the past year or two. This also assists paying other admin costs including Club membership and tips. Other Games We sometimes play other games in the evening such as Rummikub, Yahtzee, and a type of Gin Rummy... so ask and watch this space! Etiquette Just a quick reminder- it’s always nice to say thank you to the staff at the CSC when you can. Let’s also keep things warm and friendly with each other and enjoy this splendid game. If anything comes up, please feel free to have a word with me or whoever is hosting on my behalf Backgammon Rules With one or two exceptions our group plays international backgammon tournament rules. I have outlined these rules on our meetup page. My Contact Should you get lost or need to get in touch my number is: 07956 263451. Would advise you not to post messages two hours before the meetup commences as there's often chance I will not see it. Best wishes and have lots of fun on Sunday! Chris Sattaur

Blood On The Clocktower at The Greene Man

New and Experienced Players Welcome! 🤗 Ever played Werewolf, Mafia or Secret Hitler? Well this game is like that but on steroids! 😈😇 Ever watched The Traitors and wished you could have a turn? Well now you can! Suitable for complete beginners, experienced veterans and everyone in between, we Play **'Blood on the Clocktower'** a game where you never know who you can trust... A great way to meet new people in a fun interactive way, at a bar serving food and drinks Continue reading for a general description of the game: Blood on the Clocktower is a bluffing game enjoyed by 5 to 20 players on opposing teams of Good and Evil, overseen by an experienced Storyteller. During a 'day' phase players socialize openly and whisper privately to trade knowledge or spread lies, culminating in a player's execution if a majority suspects them of being Evil. At 'night' time, players close their eyes and some are woken one at a time by the Storyteller to gather information, spread mischief, or kill. Use all your powers of deduction and deception to survive this game of murder and mystery. The game will be fully explained at the event. However if you'd like to learn more now watch: https://youtu.be/M-aZP47Nm9g?feature=shared
