Rendering – BRDF – Bidirectional reflectance distribution function
Read more: Rendering – BRDF – Bidirectional reflectance distribution functionhttp://en.wikipedia.org/wiki/Bidirectional_reflectance_distribution_function
The bidirectional reflectance distribution function is a four-dimensional function that defines how light is reflected at an opaque surface
http://www.cs.ucla.edu/~zhu/tutorial/An_Introduction_to_BRDF-Based_Lighting.pdf
In general, when light interacts with matter, a complicated light-matter dynamic occurs. This interaction depends on the physical characteristics of the light as well as the physical composition and characteristics of the matter.
That is, some of the incident light is reflected, some of the light is transmitted, and another portion of the light is absorbed by the medium itself.
A BRDF describes how much light is reflected when light makes contact with a certain material. Similarly, a BTDF (Bi-directional Transmission Distribution Function) describes how much light is transmitted when light makes contact with a certain material

It is difficult to establish exactly how far one should go in elaborating the surface model. A truly complete representation of the reflective behavior of a surface might take into account such phenomena as polarization, scattering, fluorescence, and phosphorescence, all of which might vary with position on the surface. Therefore, the variables in this complete function would be:
incoming and outgoing angle incoming and outgoing wavelength incoming and outgoing polarization (both linear and circular) incoming and outgoing position (which might differ due to subsurface scattering) time delay between the incoming and outgoing light ray

Space bodies’ components and light spectroscopy

This help’s us understand the composition of components in/on solar system bodies.
Dips in the observed light spectrum, also known as, lines of absorption occur as gasses absorb energy from light at specific points along the light spectrum.
These dips or darkened zones (lines of absorption) leave a finger print which identify elements and compounds.
In this image the dark absorption bands appear as lines of emission which occur as the result of emitted not reflected (absorbed) light.

Brian Gallagher – Why Almost Everybody Is Wrong About DeepSeek vs. All the Other AI Companies
Benchmarks don’t capture real-world complexity like latency, domain-specific tasks, or edge cases. Enterprises often need more than raw performance, also needing reliability, ease of integration, and robust vendor support. Enterprise money will support the industries providing these services.
… it is also reasonable to assume that anything you put into the app or their website will be going to the Chinese government as well, so factor that in as well.

Ben Gunsberger – AI generated podcast about AI using Google NotebookLM
Listen to the podcast in the post
“I just created a AI-Generated podcast by feeding an article I write into Google’s NotebookLM. If I hadn’t make it myself, I would have been 100% fooled into thinking it was real people talking.”

Jeffrey Ian Wilson – The Hidden Risks of Using ChatGPT and Anonymous AI Tools in non-secured Confidential Workflows Outside Proper Production Pipelines

What You Can Do Today
If you’re serious about protecting your IP, client relationships, and professional credibility, you need to stop treating generative AI tools like consumer-grade apps. This isn’t about fear, it’s about operational discipline. Below are immediate steps you can take to reduce your exposure and stay in control of your creative pipeline.
- Use ChatGPT via the API, not the public app, for any sensitive data.
- Isolate ComfyUI to a sandboxed VM, Docker container, or offline machine.
- Audit every custom node, don’t blindly trust GitHub links or ComfyUI workflows
- Educate your team, a single mistake can leak an unreleased game asset, a feature film script, or trade secrets.
- Open source does not mean secure.

Remote working pros and cons
Read more: Remote working pros and conswww.leforttalentgroup.com/business-blog/is-the-genie-out-forever
Cons of remote working:
- 1-Prefer 2 distinct locations in life — 1 for work, 1 for everything else
- 2-Being able to manage the group of employees in one location is preferable — Meetings, training, management of teams and personalities has been easier.
- 3-Confidentiality and Security — depending on the nature of the business, being able to lessen liabilities by containing the work location
- 4-Social community — Many fully enjoy the traditional work community and build life long connections
- 5-Love — A quick Google search shows various sources that cite anywhere from 20-33 percent of people met their spouse through work. What will those stats look like in a year or two from now?
- 6-Road Warriors with great sound systems in their cars — Some enjoy the commute to unwind after work cranking tunes or catch up with friends and family waiting for the gridlock to ease. Others to continue working from the car.
Pros of remote working:
- 1-The overhead costs — Keeping large commercial real estate holdings and related maintenance costs
- 2-Killer commutes — 5-20 hours/week per employee in lost time now potentially used for other purposes
- 3-Daily Daycare Scramble — Racing to drop them off or pick them up each day
- 4-Environmentally, a lower carbon footprint — Less traffic, less pollution
- 5-Quality Family time — Many parents are spending more time with their growing children
Some useful tips about working online:
- Clarify and focus on priorities.
- Define and manage expectations more explicitly than normal (give context to everything)
- Log all your working hours.
- Learn about and respect people’s boundaries.
- Pay attention to people’s verbal and physical cues.
- Pay attention to both people’s emotional, hidden and factual cues.
- Be wary about anticipating, judging, rationalizing, competing, defending, rebutting…
