C++ on Sea is an international C++ conference taking place by the sea, in the UK. Our current physical venue is in Folkestone, near the entrance to the channel tunnel.

For 2022 we returned to an in-person format. Our keynote speakers were Hana Dusíková, Kevlin Henney and Jason Turner.

Free barista coffee, thanks to Sonar

1st July 2022 at 20:32

If you're joining us next week (and if not - there's still time to buy tickets) as well as the great technical content, meeting old friends and making new, you'll also enjoy free tea, coffee and a buffet lunch.

The coffee is fine, but bulk-produced, one-size-fits-all, conference coffee will never be a match for hand prepared barista coffee.

So this year we've teamed up with Sonar, "the home of {clean code}", one of our sponsors, who are covering the cost of a free barista coffee every day of the main conference, from the café immediately upstairs from the venue (the venue all lies below street level, built into the cliffs. When you enter at street level you'll be in the café).

So when you arrive and get your conference bag, be sure to check for your three Sonar coffee tokens, as you'll need these to redeem for your free coffee in the café.

Just be mindful that if everyone hits the café at the same time the queue may become unmanageable - so try to choose different times during the day. Remember the trusty conference coffee urns will still be there to keep you going!

Don't drink coffee? Feel free to trade your tokens with someone else. That shouldn't stop you from checking out the static analysis tools that Sonar do.

C++ on Sea is hosted at the Leas Cliff Hall in Folkestone in Kent, UK, overlooking the English Channel. This historic seaside town is also home to the channel tunnel and, as such, has excellent links to the rest of europe. It's also very accessible from London with the UK's (currently) only high speed link, the HS1. For more comprehensive travel information, see the page, Getting to C++ on Sea

The Leas Cliff Hall is a working theater that also has a dedicated conference suite. Built into the cliffs, and with floor-to-ceiling glass overlooking the sea on three sides, the views are spectacular!

The venue is about a 15 minute walk from Folkestone Central station, or ten minutes walk to the bustling town centre. As well as the modern town the old quarter, home to art galleries, curio shops and bohemian cafes and restaurants, extends down to the picturesque harbour.

Although the venue is split across three floors, connected via staircases, it is also fully accessible via elevator.
