CHIIR 2020 cancelled
Unfortunately, CHIIR 2020 was cancelled. This is really sad news. I was so much looking forward to holding the tutorial on multi-method evaluation. Meanwhile, you can have a look at https://multimethods.info, which I maintain with Eva Zangerle. You can find a collection of useful material there.
Yes, it's sad, but true. CHIIR 2020 has been cancelled due to the COVID-19 health crisis. We will miss seeing you all in Vancouver. Stay healthy and CHIIR-ful, everyone! #CHIIR2020— ACM CHIIR 2023 (@ACM_CHIIR) March 6, 2020
