2014-01-24 Came across Jan Schaumann's ``Useless Use of *'' talk. [0] It matches well with my recent talk ``On Performance''. [1] Prob- ably similar to my own talk, it wasn't obvious what the essence of his talk is by only watching the slides. It became much more clear when he quickly explained his view to me, after I asked him by email. At least our general understanding is similar.
