Hello I have to make an animation with this shape, but i cant find out any tutorial to explain me the method to achieve the result I'm looking for. I would like to extrude and animate a square shaped polygon that follows the yellow arrow path so that it builds up the entire shape in red.  Thank you very much for your time.
As i am new to blender i decided to learn by recreating some animations which have some interesting problems, and gain more knowledge about how tv intros are being done, collecting some parody intros to videos. I came across a simple yet troublesome effect , found no answer by googling or getting through tutorials and testing methods on this case led me to nowhere.     I attempted to recreate the animation above, especially  the extending/appearing/drawn white strip with "randomly" placed gaps , strip which travels just above surface , casting shadow.   Tried dynamic paint,( with alpha channel) image sequence texture but although effect was very similar, whole invisible strip was casting shadow being Z transparent, in places where white color haven't reached yet.  I tried bezier curves as well(vector mode) but it appears that taper cant profile part in squary way, or maybe i am missing something here.  Shape keys seem to hard way to go , while keeping whole animation of stripe "unrolling" at constant speed.  I tried as well putting an array of planes on the path but it is completely not what i attempt to achieved.   I will edit post and add some pictures tomorrow.
How can I gzip standard in to a file and also print standard in to standard out? I want to execute a command, have the output of that command get gzip'd on the fly, and also echo/tee out the output of that command. i.e., something like: echo &quot;hey hey, we're the monkees&quot; | gzip --stdout &gt; my_log.gz  Except when the line executes, I want to see this on standard out: hey hey, we're the monkees Is there a reason I would not add /usr/local/sbin, /usr/sbin, /sbin to my path on Debian? Ubuntu 17.10 Upgrade Broke VMWare Workstation 12.5 Hi after upgrading to Ubuntu 17.10, vmware is now not starting.

Is this possible in ASP.NET MVC beta?  I've tried multiple examples:  1.      If I use this example, I receive the "Cannot redirect after HTTP   headers have been sent.".   2.      If I use this, I seem to be unable to do a redirectToAction, as it   tries to render a view that may not exist. If I do return the view, it   is completely messed up and doesn't look right at all.   Does anyone have any ideas/solutions to these issues i have, or have any suggestions for better ones?  Many thanks!  Below is an example. What I'm trying to do is create the GetViewForEmail method:  public ActionResult OrderResult(string ref) {     //Get the order     Order order = OrderService.GetOrder(ref);      //The email helper would do the meat and veg by getting the view as a string     //Pass the control name (OrderResultEmail) and the model (order)     string emailView = GetViewForEmail("OrderResultEmail", order);      //Email the order out     EmailHelper(order, emailView);     return View("OrderResult", order); }   Accepted answer from Tim Scott (changed and formatted a little by me):  public virtual string RenderViewToString(     ControllerContext controllerContext,     string viewPath,     string masterPath,     ViewDataDictionary viewData,     TempDataDictionary tempData) {     Stream filter = null;     ViewPage viewPage = new ViewPage();      //Right, create our view     viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData);      //Get the response context, flush it and get the response filter.     var response = viewPage.ViewContext.HttpContext.Response;     response.Flush();     var oldFilter = response.Filter;      try     {         //Put a new filter into the response         filter = new MemoryStream();         response.Filter = filter;          //Now render the view into the memorystream and flush the response         viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output);         response.Flush();          //Now read the rendered view.         filter.Position = 0;         var reader = new StreamReader(filter, response.ContentEncoding);         return reader.ReadToEnd();     }     finally     {         //Clean up.         if (filter != null)         {             filter.Dispose();         }          //Now replace the response filter         response.Filter = oldFilter;     } }   Example usage  Assuming a call from the controller to get the order confirmation email, passing the Site.Master location.  string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData); Command to move a file to Trash via Terminal I would like to know if there is a command I can issue in a terminal so I do not classically remove (rm) the file, but instead move it to trash (i.e. Nautilus Move to Trash behavior).

I was thinking that I can glue two of the S's together, so there will be 9 letters plus the special letter SS, and the number of arrangements will be $10!/(2!2!4!)$, this is not the correct answer, but what is wrong with my reasoning.  (the correct answer is $11!/(4!4!2!)-7!/(4!2!)\binom{8}{4}$, I understand the solution) Does untapping an attacker stop its attack?

I currently only own the Whiterun house, which has 2 bookshelves of 2 shelves each.  Is there a house I could buy that has more bookshelves?

How to generate a random alpha-numeric string I've been looking for a simple Java algorithm to generate a pseudo-random alpha-numeric string.  In my situation it would be used as a unique session/key identifier that would "likely" be unique over 500K+ generation (my needs don't really require anything much more sophisticated).    Ideally, I would be able to specify a length depending on my uniqueness needs. For example, a generated string of length 12 might look something like "AEYGF7K0DM1X". Equation System with 3 variables "Find all the possible solutions $(x,y,z) \in$  $\Bbb R$ that satisfies the following equation system".  My teacher gave me this problem and i got some clues in how to solve it. I evaluated $1$ and $-1$ and i got these solutions $(1,-1,1)$ and $(-1,-1,-1)$. I think these are the only ones but i can't prove it.  Am i wrong?, are there more solutions?.

Counterexample: $G \times K \cong H \times K \implies G \cong H$ I am having a hard time finding a counterexample for the statement: $G \times K \cong H \times K \implies G \cong H$  I think this should be true for abelian, finite groups. But is this true in general? What would be a counterexample?  Any hints appreciated!  Thanks $g^k$ is a primitive element modulo $m$ iff $\gcd (k,\varphi(m))=1$ How can I increase the JVM memory? What kind of rhetoric is (this particular) "No one ever [...]" The President also knows that we have to stop blaming victims for these crimes.  No one ever asks the person who got robbed at gunpoint in the street -- why were you there, what were you doing, what were you wearing?  What did you say?  Did you offend someone?  We encourage people to come forward.  We don't have to explain why someone took our money.     I think the "No one ever [...]" claim is literally false, and actually obviously so. So, I understand it to mean:          The President also knows that we have to stop blaming victims for these crimes.  No one in their right mind ever asks the person who got robbed at gunpoint in the street -- why were you there, what were you doing, what were you wearing?  What did you say?  Did you offend someone?  We encourage people to come forward.  We don't have to explain why someone took our money.      Supposing that I am right, what is this kind of rhetoric called?
