We hold two pub evenings a month on the first and third Wednesdays, with all the other Wednesdays being virtual pub evenings. We also normally have a monthly quiz on the last Wednesday of the month, during the virtual pub evening, at about 9pm, where a different member of our group prepares the questions and answers to be used each month. This means that tonight is a virtual pub evening but incorporating a quiz. Contact Roland in advance, preferably by e-mail, so that he can send you a link to click on at the start of the meeting. Please note the different arrangements for the first and third Wednesdays of the month.

**Hello There! And welcome to our June Gophers @ Meta event!** It's immensely exciting that we'll be visiting Meta for our June event, but with great big office comes great responsibility, so it is **CRITICAL THAT YOU HEED THESE ENTRY REQUIREMENTS!** * You MUST bring Government Issued Photo ID with you, matching the name with which you sign up to this event * You MUST complete the NDA that will be emailed to you in advance of the event, before arrival * You MUST be over 18 years old * You MUST NOT record when inside the venue * You MUST wear the lanyard provided to you on the night at all times And needless to say, if you satisfy all of those criteria and manage to make it through security without being tackled, you MUST have a lovely time otherwise you know I'll be giving you a hard stare. A massive thank you to Meta for hosting! See you all there! ==== 📓 **Agenda**📓 ===== (Certain timings and orders may be subject to change) **5:30pm onwards:** Sign-In, Food & Refreshments **6:55pm:** Introduction **7:00pm:** 🗣️ **Jon Bodner: Testing Go: From the Basics to synctest** Testing is fundamental to software engineering and as a language focused on software engineering, Go includes a wide variety of tools to ensure your code is working as expected. I’ll walk through the basics of testing in Go, and then cover some of the more advanced tools: benchmarking, fuzzing, and the new synctest package. **7:40pm:** Raffle and Break **8:00pm: 🗣️** **Oleg Obleukhov: Time @ Meta** Discover how Meta uses Go to build PTP and NTP - open-source, highly efficient time synchronization systems that achieve nanoseconds precision. **8:30pm:** Break **8:40pm: 🗣️** **Simon Emms: Failure Happens. Your Code Shouldn't Care** As Gophers, we expect our code to be retried, restarted and run more than once. The challenge is making that safe and maintainable without layers of defensive plumbing. Temporal lets us write reliable workflows in Go that automatically recover from crashes and restarts, while still looking and feeling like normal Go code. In this talk, I’ll explain how it works and prove it with a live demo that treats failure as just another code path. **9:10pm:** Raffle Winners! **9:30pm:** Pub / Socialize ==== 🎉 **Prizes & Discounts!** 🎉 ===== **JetBrains Raffle!** \- We have 3 free JetBrains Product licenses to give away to some of our lucky attendees\! **Ardan Labs Raffle!** \- We're giving away one course license for Ardan Labs' Ultimate Go Bundle\! **Manning Publications Raffle!** \- We're giving away 4 free Go e\-books\! **45% Manning Publications Discount** \- a massive discount provided by the fine people at Manning\!

So you will speak directly to the tutor who enjoys handing over his passion for his country and his mother tongue. He will support you along the way to improve your speech flow. The event consists of conversation and chats. **IMPORTANT** If you are new to our FLE Meet Up, please send ASAP an email (in French) at frenchlondonexperience at gmail dot com to introduce yourself, to check your level and to confirm your space. **PRICING:** You can pay each time or by block \- £10 per session \(to be paid immediately at the booking by bank transfer \- otherwise you will be removed from the list \- Bank details on request\) \- £60 for 6 sessions \(to be used within 3 months \- to be paid in advance by bank transfer \- Bank details on request\) As the cafe friendly welcomes us every week, it is nice for each of us to buy something while attending the session. **TERMS & CONDITIONS** If you are to join, you are more than welcome to sign up.
