A few updates to the SBCL20 arrangements:

Firstly, the venue, for planning hotel stays and similar: the Monday and
Tuesday sessions will be at Bundesrechenzentrum, in central Vienna
<https://osm.org/go/0JrJKLq1C?layers=N&m=>.

Secondly, the programme.  I expect that there will be substantial time
on both technical days devoted to unconference-like activities:
small-group discussions on crowdsourced topics; pair programming or
debugging; other ad-hoc activities driven by the attendees.  But there
will also be space for full-group contributions, such as demo and
lightning talk sessions, as well as longer talks; I'm pleased to be able
to say that Robert Smith from Rigetti Computing will be attending, and
talking about why SBCL's new powerpc64 backend matters for Quantum
Computing.

The sign-up form is at https://forms.gle/FfHF8W8ptyPfMJir8 -- as a
slight modification to the previous policy, please fill it in if you are
certainly or probably coming; we won't take the form filled in as a firm
commitment, but more than a mere expression of interest.

Best wishes,

Christophe
