I think we should make the decision about YouTube embedding independently of any other features like MathJax. From a technical point of view, YouTube embedding isn't really "expensive" the way that MathJax is, because the conversion of a link into a player happens on the server and doesn't require SE to deliver loads o... |
The data from the previous private beta is [available for download from Area 51]. It's in XML format and I'm not sure the best way to view it, but even in text form it is readable.
Is this something that it would be useful for us to look through (main and meta) for ideas? I have two conflicting feelings:

To avoid a quick shut down like the previous beta we should really maintain an high question rate. After a first day full of question, the rate dropped significantly.
I personally think we should:
- Re-ask old questions (searching for new answer) from the previous beta as [discussed here.][1]
- Ask questions... |
How do we improve the question rate? |
[This] is a question about using several GPUs. As such it sounds on topic. However, a comment shows that the parallel use of GPUs is not the main problem:
> A good answer is predicated on knowing how the displays will be connected to the available GPUs (getting 9+ display outputs on a single computer isn't trivial) ... |
What happens when a question sounds on topic but answering would go off topic? |
Some SE sites (notably SO) don't want questions about best practices as they can lead to opinionated answers. I think that is definitely a risk, but there's certainly also great value in such questions if they do get useful answers.
As an example, I have posted such a question earlier today: http://computergraphics.... |
Are questions about best practices on topic? |
The name of our site, Computer Graphics, makes perfect sense to us because we all know that it means "Computer Graphics *for programmers and researchers*". However, it won't be so clear to people who are looking for a place to ask general graphics questions, including [software usage advice like this].
Should this b... |

Monte Carlo integration is a technique frequently used in offline rendering; however, it is a very versatile method that also finds much use outside computer graphics.

Ray tracing is often introduced using direct light estimation only, often without any random algorithm, whereas path tracing usually requires Monte Carlo integration and handles indirect light.
Is that enough differentiation to have two separate tags? Or should there should be some other division? |
Should "ray tracing" and "path tracing" be separate tags? |
Just received an interesting comment to my [question][1].

Yes, questions about how to achieve or improve effect X should be on topic, but we should hold them up to certain quality standards:

We can see that the community agrees that questions should [show what you have tried], and I'm glad about this. However, [this question] asks for ways to model a situation that is never seen in everyday life.

Does an answer need explanation if it has images and links? |
"Is this enough of a reason to justify making an exception to "show what you have tried"? "
Yes.
I think probably the lack of screenshots (or other results) in the question you refer to is due to the lack of a working implementation that the asker would have achieved.
