Re:Build is a new London developer conference about the people who build software, not the hype around it. What we build, how we build it, and who we become as AI reshapes our craft. Short talks, then real conversations. No recordings. 5 & 6 May 2027 Founding tickets: rebuildcon.uk

Hello, world! We're Re:Build: a brand new developer conference in London, 5 & 6 May 2027. Built around the people who build software: craft, connection, change and humanity. Shorter talks, The Conversation, roundtables, hallway chats & a badger named Patch. Founding tickets are open: rebuildcon.uk

I'm helping at the relaunch @accuorg.bsky.social 🎉 Wed 4 Nov, 18:30, London Keynote from Meri Williams on how engineering skills improve, then Speed AMAs: private 10-min 1:1s with senior engineers: Paul Grenyer, Quasar Chunawala & Paul Ardeleanu Spaces are limited: luma.com/tpxd3p4u

Hi, I'm Kim. I build dev conferences for a living & I've decided to build a new one. I've spent the past 13 years organising dev events & conferences, most recently Devoxx UK. Between co-running the @virtualjug.bsky.social & volunteering at several other community events. Our next project 🧵

We’ve been hard at work behind the scenes & I’m excited to finally share some fantastic news! We’ve secured a venue, set the date & after much debate, we have a name. 🤩 If you're curious enough to click the link in the comments, you won't have to wait long.

Not in Amsterdam? Doesn't matter. @virtualjug.bsky.social is partnering with @amsterdamjug.bsky.social to livestream a session addressing the question every dev is asking: Did AI just break software security forever? Thu Aug 27 · 4:00–6:30 PM UTC → luma.com/8pl0y5om

We are teaming up with the @amsterdamjug.bsky.social for a special live-streamed event exploring one of the biggest questions facing devs today: Did AI Just Break Software Security Forever? Thursday, Aug 27 · 4:00 PM to 6:30 PM UTC Online event luma.com/8pl0y5om
