Signal/Noise 2027, a conference for people who build

● T-minus to doors · Thu 10 June, 09:00 CEST

Two days in Berlin for people who build. 48 talks picked blind by working engineers, six hands-on workshops, 1,400 builders and not one sponsor keynote.

Forty-eight people who’ve shipped the thing.

Every portrait here is generated from noise as the page loads, one technique per speaker, no two alike. Hover or tap a portrait and it re-acquires the signal.

    Ines Albrecht

    Staff Engineer · Kontor

    “The queue is a database now. Act like it.”

    Ines kept Kontor’s payment ledger correct at 40,000 writes a second for six years. Her keynote is about the day your message queue quietly became your source of truth, and what to do before it bites.

06.1Questions

Before you buy.

Can I transfer my ticket?

Yes, for free, until 1 June 2027. Use the link in your confirmation email and type in your colleague’s name. After 1 June we print badges, so the name is fixed.

What if I can’t come?

Full refund until 1 April 2027 and half until 1 May. After that, transfer the ticket instead. If we ever have to cancel, everyone gets everything back, including the workshop add-on.

Will the talks be recorded?

Every Hall A and Hall B talk is filmed and captioned. Ticket holders get them within 48 hours; everyone else 90 days later. Lab sessions are not recorded so people can break things in peace.

Do you send visa invitation letters?

Yes, within three working days of buying a ticket. Email [email protected] with your passport name and we send a signed letter on paper and as a PDF.

Is there a code of conduct?

Yes, and we enforce it. Two trained responders are on site for every hour of the event, reachable at the info desk or on +49 30 555 014 29. Reports are handled the same day.
