Zach Arnold – 2020: Dear Hollywood: We Don’t Want to “Go Back to Normal.” Normal Wasn’t Working
https://optimizeyourself.me/dear-hollywood-normal-wasnt-working/
Hollywood’s pre-pandemic “normal” wasn’t sustainable or healthy, particularly for workers who faced long hours, poor work-life balance, and limited diversity. This article calls for the industry to use this post-pandemic period as a chance to reform and prioritize the well-being, creativity, and inclusivity of its workforce, rather than simply returning to old, harmful practices.

AI Risk Repository – What are the risks from Artificial Intelligence?
The AI Risk Repository has three parts:
- The AI Risk Database captures 700+ risks extracted from 43 existing frameworks, with quotes and page numbers.
- The Causal Taxonomy of AI Risks classifies how, when, and why these risks occur.
- The Domain Taxonomy of AI Risks classifies these risks into seven domains (e.g., “Misinformation”) and 23 subdomains (e.g., “False or misleading information”).

AI and the Law – Artists Score Major Win in Copyright Case Against AI Art Generators
The court declined to dismiss copyright infringement claims against the AI companies. The order could implicate other firms that used Stable Diffusion, the AI model at issue in the case. The case will move forward to discovery, where the artists could uncover information related to the way in which the AI firms harvested copyrighted materials that were then used to train large language models.

Photography basics: Solid Angle measures
http://www.calculator.org/property.aspx?name=solid+angle
A measure of how large the object appears to an observer looking from that point. Thus. A measure for objects in the sky. Useful to retuen the size of the sun and moon… and in perspective, how much of their contribution to lighting. Solid angle can be represented in ‘angular diameter’ as well.

A solid angle is expressed in a dimensionless unit called a steradian (symbol: sr). By default in terms of the total celestial sphere and before atmospheric’s scattering, the Sun and the Moon subtend fractional areas of 0.000546% (Sun) and 0.000531% (Moon).

On earth the sun is likely closer to 0.00011 solid angle after athmospheric scattering. The sun as perceived from earth has a diameter of 0.53 degrees. This is about 0.000064 solid angle.

The mean angular diameter of the full moon is 2q = 0.52° (it varies with time around that average, by about 0.009°). This translates into a solid angle of 0.0000647 sr, which means that the whole night sky covers a solid angle roughly one hundred thousand times greater than the full moon.

Angular Size
The apparent size of an object as seen by an observer; expressed in units of degrees (of arc), arc minutes, or arc seconds. The moon, as viewed from the Earth, has an angular diameter of one-half a degree.
The angle covered by the diameter of the full moon is about 31 arcmin or 1/2°, so astronomers would say the Moon’s angular diameter is 31 arcmin, or the Moon subtends an angle of 31 arcmin.
