the elliptic curve signature scheme used by Bitcoin is much more at risk, and could be completely broken by a quantum computer as early as 2027, by the most optimistic estimates.It is time to re-visit the "optimistic estimates", so follow me below the fold.
I'm David Rosenthal, and this is a place to discuss the work I'm doing in Digital Preservation.

The Dawn Of Nvidia's Technology


But as regards the technical aspects of this early history it appears that neither author really understood the reasons for the two kinds of innovation we made; the imaging model and the I/O architecture. Witt writes (Page 31):
The first time I asked Priem about the architecture of the NV1, he spoke uninterrupted for twenty-seven minutes.Below the fold, I try to explain what Curtis was talking about for those 27 minutes. It will take me quite a long post.

about the reaction to the 1998 murder of gay University of Wyoming student Matthew Shepard in Laramie, Wyoming. The murder was denounced as a hate crime and brought attention to the lack of hate crime laws in various states, including Wyoming.The new play, Here There Are Blueberries, is on tour after a 2022 premiere at the La Jolla Playhouse and a 2024 run at the New York Theatre Workshop. Vinson Cunningham reviewed the New York production in The Chilling Truth Pictured in “Here There Are Blueberries”:
An example of verbatim theatre, the play draws on hundreds of interviews conducted by the theatre company with inhabitants of the town, company members' own journal entries, and published news reports.
There’s something awful about a lost picture. Maybe it’s because of a disparity between your original hope and the result: you made the photograph because you intended to keep it, and now that intention—artistic, memorial, historical—is fugitive, on the run toward ends other than your own. The picture, gone forever, possibly revived by strange eyes, will never again mean quite what you thought it would.The play dramatizes the process archivists at the US Holocaust Memorial Museum went through to investigate an album of photographs taken at Auschwitz. Photographs from Auschwitz are extremely rare because the Nazis didn't want evidence of what happened there to survive.
Below the fold I discuss the play and some of the thoughts it provoked that are relevant to digital preservation.
