I wish to create the animation of a robot on Blender and simulate the same animation in Webots to check for feasibility. For this, I'm thinking of extracting coordinate data from all objects in the scene into an external file ('.csv', for e.g.) using a python script. I wanted to create a simple scene initially and followed the tutorial here  to change cube position and create keyframes. I'm not sure how to get the coordinate data and save them on an external file. Any help would be greatly appreciated!
I'm working on a project that requires me to get some of the position and rotation values to give to an Arduino via pyserial, but after sifting through the Blender documentation I can't find how to get them through script.
How is effect precedence determined? I was using  and my opponent has a . I attacked Sylvanas, fearing that the Deathrattle will take control of one Hyena. I feel lucky, because it did not happen.  I want to know if there are some general rules of effect precedence.   Has Blizzard published something about this?  Are there articles teaching about precedence?   Please note, I want guidance about effect precedence in general, not just about Deathrattle. Is there an Extended Backus–Naur form (EBNF) that covers all of English? When to use "click" and "click on" QGIS creating a fixed distance buffer over selected areas not the entire layer what im doing is making a fixed distance buffer and it's working splendidly but i need the buffer to be created over certain selected areas not the entire layer, and at the creation wizard is only offers the the option of selecting the entire layer, and i need some areas within that layer to have a different buffer and some none at all.  is there a way around that? Replacing a font in many illustrator files I have several hundred Illustrator files that are formatted similarly, and for legal reasons I need to replace a font in all of them. Even with the 'Find font' tool, that's a hell of a lot of fonts to replace by hand.  Is there some way of automating it? For example, using Bridge? Illustrator (CS5) doesn't offer many options in Bridge, compared to the automation options offered by Photoshop. I also don't see any option for running actions on multiple Illustrator files.  Also, creating a repeatable action for replacing the font doesn't seem to work: instead of repeating my action, it brings up the dialog box an waits for me to tell it to replace them.  As a programmer I'm prepared to edit the files directly if it can be done without breaking them.    Update: The 'Batch...' menu item from Illustrator's actions panel menu allows the same action to be performed on a folder of files. It doesn't fix the Find Fonts action waiting for input though. Toggling the dialog off makes the action do nothing at all. motion tracking : how to extract 3d position from selected 2d tracker I already solve my camera and created 3d scene successfully. Now i want to do 2d track the original clip and by using solving data, i want to extract that specific point into 3d coordinate (as empty object or plain axes). How can i do this ?  Thanks $f(x)=x^3$ is convex nor concave without to derivate Why does cancellation of dots $\frac{\partial \dot{\mathbf{r}}_i}{\partial \dot{q}_j} = \frac{\partial \mathbf{r}_i}{\partial q_j}$ work? Back-transformation of regression coefficients I'm doing a linear regression with a transformed dependent variable. The following transformation was done so that the assumption of normality of residuals would hold. The untransformed dependant variable was negatively skewed, and the following transform made it close to normal:   $$Y=\sqrt{50-Y_{orig}}$$  where $Y_{orig}$ is the dependent variable on the original scale.   I think it makes sense to use some transformation on the $\beta$ coefficients to work our way back to the original scale. Using the following regression equation,   $$Y=\sqrt{50-Y_{orig}}=\alpha+\beta \cdot X$$  and by fixing $X=0$, we have   $$\alpha=\sqrt{50-Y_{orig}}=\sqrt{50-\alpha_{orig}}$$  And finally,  $$\alpha_{orig}=50-\alpha^2$$  Using the same logic, I found  $$\beta_{orig}=\alpha\space(\alpha-2\beta)+\beta^2+\alpha_{orig}-50$$  Now things work very well for a model with 1 or 2 predictors; the back-transformed coefficients resemble the original ones, only now I can trust the standard errors. The problem comes when including an interaction term, such as  $$Y=\alpha+X_1\beta_{X_1}+X_2\beta_{X_2}+X_1X_2\beta_{X_1X_2}$$  Then the back-transformation for the $\beta$s are not so close to the ones from the original scale, and I'm not sure why that happens. I'm also unsure if the formula found for back-transforming a beta coefficient is usable as is for the 3rd $\beta$ (for the interaction term). Before going into crazy algebra, I thought I'd ask for advice... Measuring accuracy of a logistic regression-based model Getting ssh to execute a command in the background on target machine This is a follow-on question to the  question.  If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return?  When I try to just include the ampersand (&amp;) at the end of the command it just hangs.  The exact form of the command looks like this: ssh user@target &quot;cd /some/directory; program-to-execute &amp;&quot;  Any ideas?  One thing to note is that logins to the target machine always produce a text banner and I have SSH keys set up so no password is required. I encountered an 'errorUnknown graphics extension: .eps.' I tried to load an .eps picture, but an error occured,      errorUnknown graphics extension: .eps. I have a COM dll written in vb6. When I try to create a new object of a class module from this dll I get a Run timer error 430: Class does not support automation or does not support expected interface. The interesting thing is that this happens only from outside the IDE, when I am debugging from within the IDE there is no error thrown and the new object of the class is created successfully. What can be the cause?  In general I occasionally get these kind of errors in COM dlls. What is the best way to debug COM issues? How can I know the path of the dll that is being used when a program is running? Applying MVT and IVT (?) to show something about f'''?

Image from this How can gravity affect light? I understand that a black hole bends the fabric of space time to a point that no object can escape.   I understand that light travels in a straight line along spacetime unless distorted by gravity. If spacetime is being curved by gravity then light should follow that bend in spacetime.  In Newton's Law of Universal Gravitation, the mass of both objects must be entered, but photon has no mass, why should a massless photon  be affected by gravity in by Newton's equations?  What am I missing? I came across the following problem in a book:  Give a combinatorial proof of  $$ {n \choose 0} + {n \choose 2} + {n \choose 4} + \, \, ... \, = {n \choose 1} + {n \choose 3} + {n \choose 5} + \, \, ...$$ using the "weirdo" method (i.e., where one of the elements is chosen as special and included-excluded -- I'm sure you get the idea).  After days of repeated effort, the proof has failed to strike me. Because every time one of the elements is excluded, the term would be ${n-1 \choose k}$ and not $ {n \choose k}$, which is not the case in either of the sides of the equation.
