(of course one should account for the 5 seconds of downtime they have almost every single night when stuff reboots or upgrades. It's not great.)

Geometric Measures of Complexity for Open and Closed Quantum Systems
The unitary dynamics of quantum systems can be modeled as a trajectory on a Riemannian manifold. This theoretical framework naturally yields a purely geometric interpretation of computational complexity for quantum algorithms, a notion originally developed by Michael Nielsen (Circa, 2007). However, for nonunitary dynamics, it is unclear how one can recover a completely geometric characterization of Nielsen-like geometric complexity. The main obstacle to overcome is that nonunitary dynamics cann…

Programmable spatiotemporal OAM optical toroidal beams with completely tunable properties
Spatiotemporal toroidal orbital angular momentum (OAM) beams are a developing class of spatiotemporal beams which have key applications within quantum physics, metrology, imaging and optical manipulation. However, the full realization of these applications require complete configurability within tunable temporal duration, 3D geometric structure and OAM charge of these beams along with amplitude, phase and polarization control. In this paper, we demonstrate complete configurability of programmab…

Watching The Martian (2015). It features a plot point where only the Chinese space agency can rescue the American mission. So of course they all cooperate and get the thing done.

Designing for Learning with Generative AI is a Wicked Problem: An Illustrative Longitudinal Qualitative Case Series
Students continue their education when they feel their learning is meaningful and relevant for their future careers. Computing educators now face the challenge of preparing students for careers increasingly shaped by generative AI (GenAI) with the goals of supporting their learning, motivation, ethics, and career development. Our longitudinal qualitative study of students in a GenAI-integrated creative media course shows how this is a "wicked" problem: progress on one goal can then impede progr…

OH on Haight St: "it's raining, I don't think we can do the park today"
I, of course, had to respond that it's just our July sunscreen lotion.

A "watch your replay videos" reflection assignment on comparing programming without versus with generative AI: learning about programming, critical AI use and limitations, and reflection

A "watch your replay videos" reflection assignment on comparing programming without versus with generative AI: learning about programming, critical AI use and limitations, and reflection
Generative AI is disrupting computing education. Most interventions focus on teaching GenAI use rather than helping students understand how AI changes their programming process. We designed and deployed a novel comparative video reflection assignment adapting the Describe, Examine, then Articulate Learning (DEAL) framework. In an introductory software engineering course, students recorded themselves programming during their team project two times: first without, then with using generative AI. S…

Calamus 41 Among the men and women, the multitude
A sweet poem about having a conceptual soulmate. What's interesting to me is how clandestine the connection is
one picking me out by secret and divine signs...
I meant that you should discover me so, by my faint indirections
This feels very gaydar / cruisy to me.

Why do we have to beg button to cross anywhere in Mission Rock/Bay? It's supposed to be transit and pedestrian rich.

Fun new summer music video, is out, Kesha’s Boy Crazy. It’s a basic pop/hiphop bop, featuring various images of Kesha surrounded by her boy toys. Only some of her boy toys are well over the age of 60.
