At the Nordic Numerical Linear Algebra workshop, this year in Odense, Denmark. The second keynote by Alex Townsend from Cornell University via zoom. Worked very well, and was sustainable.

He says that you don't meet the Kahan matrix in a dark alley. Or otherwise put: Many worst case estimates are not representative of what happens in practice.

Also a very nice presentation of methods to compute the numerical rank of matrices.

At the Nordic Numerical Linear Algebra workshop, this year in Odense, Denmark. Interesting keynote by Erin Carson from Charles University about the state of the art on mixed precision iterative methods. Highly relevant in the new heterogeneous hardware world, e.g. the Hopper chip.
