!!Con (pronounced “bang bang con”) 2024 is two days of talks on August 24 and 25 to celebrate the joyous, exciting, and surprising moments in computing. Established in 2014, we're an independent, nonprofit tech conference consisting almost entirely of ten-minute lightning talks!

On the agenda this year are two amazing keynote talks and 31 lightning talks. Among other topics, our attendees will hear about analog computing, braille, cosmic rays, textile dataviz, and the Voyager 1 spacecraft. In between talks, enjoy lunch (provided on both days), coffee, and other refreshments, as well as plenty of breaks and unconferencing time!

Here’s what some past !!Con speakers and attendees said about us:

• “Going to !!Con rekindled my love of computing and changed my entire career trajectory. Most fun I’ve ever had at a tech event!” – Geoffrey Litt
• ”@bangbangcon managed to pack more useful info into one day than most other conferences do in 3. And it was 10x more fun.” – John Wittrock
• “It’s refreshing to learn 30+ new things about programming in a single weekend at @bangbangcon, even though I’ve been programming for so long” – Melody Starling
• “@bangbangcon was awesome! Learned a lot, met very friendly people, and left inspired.” – Bomani McClendon

You can attend !!Con 2024 either in-person or online! To join us in person, you’ll need to have a ticket – go get one! As always for !!Con, tickets are pay-what-you-want. This year, we’ve set a suggested ticket price of $256 – it turns out that running an outdoor conference gets really expensive really quickly. If you can, please consider paying $256 for your ticket (or, if you can afford it, more, so that folks who haven’t got the means can come and we can still run the event!). But we want you at the conference regardless, so if you can’t afford $256, please register anyway and pay what you can afford!

We’re also offering online-only tickets, with a suggested donation of $8. Buying an online-only ticket will get you access to our 2024 Discord server. Discord was a popular feature of the online-only !!Cons in 2022, 2021, and 2020. In-person attendees will get access to the Discord too.

And, as always, our live stream will be public and free for everyone, no ticket required!
