As most of you are painfully aware, Linux Plumbers Conference registrations can run out very fast (yes, we got lots of complaints last year). This year, we’re taking a couple of steps to alleviate the issue. Firstly, we’re expanding the venue size in Prague to match the number of attendees we got in Vienna (800) which will hopefully mean we have more than enough places to keep registration open all the way up to the beginning of the conference. Secondly, we’re going to have an pre-registration period starting two weeks before general registration opens for anyone who submits content. The way this will work is that if you submit anything via indico before general registration opens, you’ll receive a voucher and instructions to participate (this applies to every track and MC submission regardless of the accept/reject or pending state). The cost will be the same as general registration (US$600) but you’ll be under no obligation to take up the voucher, which will expire when general registration opens. We’re aligning the acceptance/rejection notices of the tracks we directly control (Refereed and Kernel Summit) to be complete around the time we open pre-registration. However, for other tracks and MC submissions that aren’t aligned, if you take up an early registration voucher but are subsequently offered a free pass, we’ll refund it (although if your company pays, we’d appreciate not having to since cvent charges us).
As a reminder of free pass distribution: every accepted Track Speaker (Refereed, Kernel Summit, Net, BPF and Toolchain) gets a free pass. However, Microconferences operate differently and accepted Microconference discussion leads may not receive a free pass (Microconferences have two free passes each and can distribute them arbitrarily to encourage key attendees).
The anticipated date for the opening of early registration is Friday 10 July 2026, but remember this may change due to logistical problems with the cvent website (which we don’t control).
