I've tried to render my scene but there's an object that won't show up. I've checked the camera, I've checked the visibility, it isn't hidden and it's showing in the viewport. I feel like I've opened every setting and have achieved nothing. I’m trying to render a book with a cover, flipping pages and stacks of pages. I have no idea how to fix the fact that the book cover doesn’t render. If I create a plane and select both the book cover and the plane and join them with Ctrl+J, the render contains a book cover but it doesn’t turn as it’s rigged to do so because it’s now linked to the plane and loses all the animated properties. As soon as I unjoin them the book cover stops rendering and everything appears as you see it there, a book with binding, pages, but no cover. For the life of me I cannot figure out what’s going on. Here is an image of what I want it to look like with the insufficient fix:  Here is an image of what it comes out like:  Here is an image of the settings in my project:  Here is an optional link to my project:

My Windows 10 notebook died but fortunately I was able to rescue the hard drive and put it into another PC.   Unfortunately, the other PC can't open the C/Users/Joe folder. What do I have to do to open the folder? Voting to Close after Accidentally Voting to Leave Open When reviewing on SO, I accidentally pushed the "Leave Open" button on a post that clearly should've been closed. I pushed the back button and saw that in the review panel my vote to keep open had been locked and it said:     PhpMyCoder voted to leave open 1 minute ago   So I clicked on the question heading to go to its page and I clicked the close link on the question page and voted to close for the relevant reason. However, when I returned to the review page (and did a hard refresh) it still said:     PhpMyCoder voted to leave open 2 minutes ago   Is it possible to vote to leave open and vote to close at the same time? I assume not. In which case, I'd say this is a bug because it should've updated to say:     OtherUser and PhpMyCoder voted to close 2 minutes ago Formula to add minutes to date+time in Excel If I have a cell formatted as date+time in Excel, how can I add to this in terms of minutes? It would need to work whether I was adding 20 minutes, or 2,500 minutes.   So, for example if I had this spreadsheet, what formula could I put in B5 to get a result of 2013-09-22 09:10?    I tried using =B4+TIME(0,B3,0), but it gives 2013-09-21 09:10 which is a day off. It works fine though if B3 is less than a day's worth. How can I evaluate $\sum_{n=0}^\infty(n+1)x^n$? How can I evaluate $$\sum_{n=1}^\infty\frac{2n}{3^{n+1}}$$? I know the answer thanks to , but I'm more concerned with how I can derive that answer. It cites tests to prove that it is convergent, but my class has never learned these before. So I feel that there must be a simpler method.  In general, how can I evaluate $$\sum_{n=0}^\infty (n+1)x^n?$$ Im very new at LaTeX and I would appreciate some help solving this problem. I have created a BibTeX file containing all references to a document. In this text file BibTeX items are inserted and no other text are written, for instance @article{...}. When I call for this bib file from the main.tex file I use the commands:  \bibliographystyle{plain} \bibliography{thebibliography}   Now to my question. All i get when I compile this main.tex is the title (bibliography) for this chapter, otherwise the textfield is blank. Is this error occurring because I should write anything in the bib file or have I missed any lines in the main.tex file. Is there a term for when just by saying that something is broken and showing it to someone fixes the issue? This seems to be a common enough occurrence that it would merit its own phrase. I imagine it might be some sort of subset of Murphy's Law. But it's specific enough that Murphy's Law doesn't quite address it.  Do you know when you are banging your head against a wall for hours trying to fix something? And then when you finally give up and try to get someone else to come fix it (or even just look at it to see that it's broken), it's working perfectly as if nothing had ever happened? And at this point, you're just trying to convince the other person that it was broken in the first place.  It'd at least take some of the frustration out of the experience if you could both just laugh about &lt;insert the phrase for it here&gt;. But as it is now, I basically have to go through the whole paragraph above to say it, and at that point the joke is kind of lost. After reading some articles on blender speed, I see that using CUDA enabled GPU computing will be of help in rendering.   I am trying to stitch a shirt on human .obj file. For that I bake 60 frames for it to fall on the human correctly. It takes about 20 seconds for the bake. I'd want to host it real time.  youtube link of the same :   Can I use GPU computing to reduce the bake time just like rendering time ? How to find all graph isomorphisms in FindGraphIsomorphism I accidentally changed /var owner/group to my username and then changed it back to root, but not all the /var folders' owners are root, so is there anyway to change back owner/group of files/folders to default state?  Or at least those files/folders that are created by packages? iMac only show flashing folder with question mark after formatting OS X partition drive Today i format my "OS X El capitan" partition for installing "Yosemite". But due an error in bootable yosemite usb it didn't install on this partition. After some hours when i turned on iMac and hold down "option" key for boot into usb but just blank screen and mouse show. And every time when i turend on iMac it only show flashing folder with question mark. I've tried to resolve it by reseting "NVRAM". But after restarting problem still same.  Also I've tried many "Startup key combinations for Mac" but didn't work any combination on startup.  Also i have important data in my other one partition. Please can anyone tell me what i do for resolving that issue Without loosing my data? How does Star Trek bridge crew spend their time when on duty? It's implied that the Enterprise bridge crew, in any of the TV series, spend long durations at their duty stations, either sitting or standing.  What exactly are they doing for hours on end while the Enterprise is en route between destinations? Is it me or does this seem like an incredibly tedious if not fatiguing job, sitting in a chair staring at the same view screen? Couldn't these tasks be automated? I built a simple bridge rectifier.         &ndash; Schematic created using   I connected the output of the function generator with CH1 of my oscilloscope and  with the input of the rectifier (using a T-Piece). The output goes into CH2.   The original wave looks like this:    After connecting CH2 the picture looks like this:   While CH2 looks good,  CH1 now shows the wave I would expect without capacitator but not the expected original wave.   Could somebody explain why? I'm using a Gwinstek GDS-1072A-U Oscilloscope and a Gwinstek SFG-1003 function generator. How can I execute a file without giving myself execute permissions (with chmod u+x) for it?   If I try and tick the 'Allow executing file as program' checkmark, the checkmark is immediately removed. input() error - NameError: name '...' is not defined What was the inspiration for the design of R2-D2? Looking at R2-D2, I can't think of any robots I've seen in science fiction that vaguely resemble R2D2's design.  What was the inspiration for the design of R2-D2? Is it possible to view the latex code after Lua expansion is made? When using Lua code inside Latex file, where Lua code sends to Tex Latex code to insert into the document at the location the lua code is made, it will be useful to look at the content of Latex file (internal) after the expansion is made but right before the file is compiled to pdf. This can help in debugging and in many other cases.  Is there an option to do this?  A small example will help explain what I mean.   Given this latex file  \documentclass{article} \usepackage{luacode} \begin{document}  The following is my table  \begin{luacode} i=6 j=8 tex.print("\\begin{tabular}{|l|l|}\\hline") tex.print(i.."&amp;"..j) tex.print("\\\\ \\hline") tex.print("\\end{tabular}") \end{luacode}  \end{document}   Compiling this gives the pdf file:    What I'd like to now see is the Latex file that would resulted after the Lua code expansion, which should be something as follows  \documentclass{article} \usepackage{luacode} \begin{document}  The following is my table  \begin{tabular}{|l|l|}\hline 6 &amp; 8 \\\hline \end{tabular}  \end{document}   I could not find an option to do this so far.  TL 2015    Update  Another example to make clear what is being asked here. I'd like to see not only the latex code that was generated from the lua bits of code, but the full Latex document that would result after all the expansion of all lua code in the original Latex. But this has to be done without modifying the original Latex document itself.   Assuming there is this virtual pipeline:  Latex file -&gt; Lua code expand -&gt; Updated Latex (internal)-&gt; lualatex -&gt;pdf    I'd like to get a copy of the full latex code/file just after all the lua code expanded.  Here is another example. Given this Latex file input:  \documentclass{article} \usepackage{luacode} \begin{document} The following is my table \begin{luacode*} i=6 j=8 tex.print("\\begin{tabular}{|l|l|}\\hline") tex.print(i.."&amp;"..j) tex.print("\\\\ \\hline") tex.print("\\end{tabular}") \end{luacode*}  Our annual budget for the company is \luaexec{tex.print(200*15^3)} dollars as  shown in this list of items \begin{luacode*}  tex.print("\\begin{itemize}")  for i=1,5 do    tex.print("\\item "..i^2)  end  tex.print("\\end{itemize}") \end{luacode*} And so on. \end{document}   The PDF is    I'd like to get a copy of the following latex file, which has all the Lua code expanded and gone and only the Latex code is left in its place. This file can go to a temporary file, or anywhere, as long as it is the complete Latex file as shown and not bits and pieces. This would be very useful in debugging when there is lots of Lua code in different places in the original Latex file.  \documentclass{article} \usepackage{luacode} \begin{document}     The following is my table  \begin{tabular}{|l|l|}\hline 6 &amp; 8 \\\hline \end{tabular}  Our annual budget for the company is 675000 dollars as  shown in this list of items  \begin{itemize} \item 1 \item 4 \item 9 \item 16 \item 25 \end{itemize}  and so on     \end{document}   I hope now the question is even more clear :) Suppose $m_1, m_2, m_3,\ldots, m_k &gt; 1$ and not necessarily pairwise relatively prime. Also $a_1, a_2,\ldots, a_k\in\Bbb Z$. What can we say about the solutions of the following congruence equations: $\begin{align*} x&amp;=a_1\mod m_1\\ x&amp;=a_2\mod m_2\\  &amp;\phantom{1}\vdots\\ x&amp;=a_k\mod m_k \end{align*}$ I had booked a ticket for travel through Indian Railways using IRCTC and got a confirmed ticket. While booking, I forgot to mention the details of a one year old child who will also be traveling.     Will it create any problem while boarding the train? In a document I'm writing, I'm using the familiar  option for my floating tables, and I  them. I'd like to avoid repeating that every time I'm creating a table. I assume it's easy to add something in my preamble that makes sure that these two options are used every time I begin a new table environment?  \documentclass{article} \begin{document} \begin{table}[hbt] \centering \begin{tabular}{*3{l}} 1 &amp; 2 &amp; 3\\ a &amp; b &amp; c\\ \end{tabular} \end{table} \end{document} When should parents stop changing clothes in front of children?
