I am having trouble rendering my animation When I click Render animation it will give me 40 blank images. The frames are all correct. I think I messed around with the settings too much. I am quite new to blender, also I'm  using blender 2.79. Here's the file.
A scene I made is not rendering, at all. This grey screen stays the same and nothing changes.  Here are my settings:  [
How do you do Impersonation in .NET? Is there a simple out of the box way to impersonate a user in .NET?  So far I've been using  for all my impersonation requirements.  Is there a better way to do it by using .NET Framework?  I have a user credential set, (username, password, domain name) which represents the identity I need to impersonate. The  prohibited the development or use of cloaking technology by the Federation. This treaty was a peace treaty and use of cloaking technology in one's own space couldn't disturb peace. Plus, the Romulans already had cloaking technology, so banning it was unfair for the Federation. So, why was this ban introduced?  Another thing: There were many things to ban, but why cloaking technology? So Black Holes Actually Merge! In 1/5th of a Second - How? I've read a lot of conflicting answers in these forums. However, today saw the awesome announcement of gravitational waves. Two black holes merged:   Not only that, they merged FAST. In 1/5th of a second revolving around each other 250 times a second. The entire event was quicker than a heartbeat. Moreover, we observed this happening as distant outsiders. So now we can say for sure:   Objects approaching the event horizon DO NOT appear to slow down Black holes CAN merge in a finite (and quick) amount of time And all this is wrt a frame of reference far, far away   To quote the NYTimes article:  One of them was 36 times as massive as the sun, the other 29. As they approached the end, at half the speed of light, they were circling each other 250 times a second.  And then the ringing stopped as the two holes coalesced into a single black hole, a trapdoor in space with the equivalent mass of 62 suns. All in a fifth of a second, Earth time.  However, everything I've read so far has let me to believe that an outside observer should never be able to measure the collision happening in a finite time. So what exactly is happening here? I must have read at lest 5 different versions of this so far everywhere in these forums over the past several years. class and private variables How do I switch back to python2 after Anaconda set python3 as the default? Recently, I installed  on my 15.04 and ended up with this!  :~$ python --version Python 3.5.1 :: Anaconda 2.5.0 (64-bit)  :~$ python2 --version Python 2.7.9  :~$ python3 --version Python 3.5.1 :: Anaconda 2.5.0 (64-bit)   During the last moments of installation, I did enter something as yes in hurry, and I suppose it had to do something with this. (Ok, my fault, I should have handled that carefully, but I need help now, not criticism).    AFAIK this is definitely going to break other programs. What do I do now?    What I think could work.  Can this be done using aliases?  alias python=python2   But I ain't sure. At work we have a Domain Controller running Server 2008 R2. Our desktop support group has the ability to join computers to the domain using their network credentials. We are now running into a problem where if the name of the computer that is being joined is the same as an existing computer on the domain, the existing computer will get a "The trust relationship has failed..." error and will not authenticate at all unless someone logs in as a local admin, changes the computer name and rejoins it to the domain.  I want to make it so that Desktop Support can only join computers with unique names to the domain. If the name already exists on the domain the operation should fail. Looking through TechNet it looks like this functionality exists but I can't seem to find out how to enable it.  Any ideas? I have 2-3 different column names that I want to look up in the entire DB and list out all tables which have those columns. Any easy script? How do I find out which DOM element has the focus? algebra - matrices and polynoms $T:\mathbb P_2[x]↦\mathbb P_2[x]$ s.t.:   $T(1)=3+2x+4x^2$, $T(x)=2+2x^2$, $T(x^2)=4+2x+3x^2$.   Is there base $B$ of $\mathbb P_2[x]$ that $[T]_B$= \begin{bmatrix}     2 &amp; 0 &amp; 0\\     -1 &amp; 1 &amp; 0\\     5 &amp; 0 &amp; 4\\  \end{bmatrix}  Please help. Thanks. How do I remember which units counter which in StarCraft 2? Distributional Laplacian of logarithm and the Dirac delta distribution Consider $S(\mathbb{R}^2)$ .  Consider $F(x) = \displaystyle\frac{1}{2 \pi} \ln|x| , x \in \mathbb{R}^2 - \{ 0 \}$.  I want to prove this  : $\Delta F = \delta $ in $S^{'}(\mathbb{R}^2).$  My try: For every $\varphi \in S({\mathbb{R}}^2)$ we have  $$\langle \Delta F, \varphi\rangle  = \langle F , \Delta \varphi\rangle  = \displaystyle\int_{\mathbb{R}^2} F(x) \Delta\varphi(x) \ dx = \displaystyle\lim_{r \rightarrow + \infty} \displaystyle\lim_{\epsilon \rightarrow 0^{+} } \displaystyle\int_{\epsilon \leq |x| \leq R} F(x) \Delta \varphi(x) \ dx $$  I don't know how to prove this :$\displaystyle\lim_{r \rightarrow + \infty} \displaystyle\lim_{\epsilon \rightarrow 0^{+} } \displaystyle\int_{\epsilon \leq |x| \leq R} F(x) \Delta\varphi(x) \ dx = \varphi (0) = \delta(\varphi)$  I don't know what to do from here. Prove that $\left (\frac{a^2 + b^2 +c^2}{a+b+c} \right) ^ {(a+b+c)} > a^a b^b c^c$ Prove that $\left (\dfrac{a^2 + b^2 +c^2}{a+b+c} \right) ^ {(a+b+c)} &gt; a^a b^b c^c$ if $a$, $b$ and $c$ are distinct natural numbers.  Is it possible using induction? I'm hoping someone can give me a nudge in the right direction...     Let $F$ be a finite field, and let $f(x)$ be a nonconstant polynomial whose derivative is the zero polynomial.  Prove that $f$ cannot be irreducible over $F$.   I've got that every root of $f$ is a multiple root and that for $F=\mathbb{F}_{p^r}$, the exponent of every term of $f$ is a multiple of $p$. Elantech Touchpad not working on Ubuntu 16.04 and Arch Linux So I have and Asus R558UF notebook with an Elantech Touchpad. After installing Ubuntu 16.04, the touchpad worked once but after restarting, it failed to work and has not been working ever since.  This is output of xinput:   ↳ Elan Touchpad                            id=12   [slave  pointer  (2)]   In Mouse and Touchpad settings, the touchpad is enabled. What should I do to fix this? Simple programs with tutorials for beginners in graphic design? Is there a way to see who voted on your posts? "Where" exactly are complex numbers used "in the real world"? I currently have a masters degree in an engineering field and I don't currently have any PhD degrees (I may study for a doctorate degree in future). It happens that when I go to conferences or scientific occasions, even in the emails I receive from people; they use a doctor prefix for my name; but I do not have a PhD degree.  What is a good etiquette to deal with such thing? Should I directly tell them that I do not have a doctorate degree? Or should I neglect such a mistake by them and don't do anything?  I think it is unethical not to correct such thing, because the person may still think that I have a PhD degree; and such wrong usage of title should be corrected some way. Once a person used doctor title for my name in an email and I just added a line in my reply to his email, stating that I have a masters degree. I often find myself wishing SO supported drag and drop. For example I drag a tag to my favs and it would add it, or when searching by tag I would like to drag the tag to the search box and get [asp.net] added in the search box.   Does it make sense to add this feature or is it just too much work for so little use? How can I propose a new site?
