In the new Star Wars trailer, we see an old Han and a Chewbacca who looks the same.  How long do Wookiees live? Is there any canon information on whether or not Wookiees age?
How old is Chewbacca, anyway? Do Wookiees get gray fur when they are old?
How can a particle's position be random and uncertain in quantum mechanics if it is already pre-determined in relativity? Identify a short story about post-apocalyptic household robots Media: Short story collection When I read it: 2011 but the story itself was much older (unsure how much) so this information only serves to clarify that it is by no means new. Plot summary: A futuristic home with household robots that help around the house (cooking, cleaning etc.), we learn about their routines and behaviour and later on it's revealed that nobody is home, in fact everyone is dead, and a description of the outside seems to imply post-nuclear apocalypse. Setting: I seem to remember snow or winter What it isn't: with Google I stumbled upon  by Ray Bradbury, and  is very similar, and the beginning made me think "Bingo!", but I do not remember there being a fire in the story I read, and I also remember a view from a briefly opened door, or window, of a snowy setting, so while it may be that I am confusing elements of another story, or my imagination, with There Will Come Soft Rains, I would still like to run this through here as a question, because I'm not convinced. Additional info: The short story collection had other short stories that I will include as I remember them, details will be fuzzy:   Meteor, by John Wyndham , by Charlotte Perkins Gilman A short story about a man who is driving a car and it is revealed in the end that he was dead the whole time , by Charles Dickens How to apply the same style to different columns? For many of my datasets I have the same imported data duplicated numerous times, each iteration displaying the data values for a different column (in my case it's fish catch weight per gridded cell per year, so lots of iterations of the same grid, with a different pattern of values per year).  For presentation purposes, it strikes me as helpful to use the same scale for each year, so I go to the original data and divide the maximum value into (arbitrarily) 10 classes and manually input the values and labels after setting the desired colour ramp and input data field:   This is extremely tedious, not just the manual excel calculation part, but also the input interface for the values &amp; labels*, hence my intention to make use of the 'save style' option. HOWEVER: when I save the style as QML and load it for the next layer, it saves everything - including the data field (in my case, year). When I change this field, QGis automatically generates the values &amp; labels based on the data for that field, ditching all of the values &amp; labels I set.   Is there any way to avoid this happening &amp; thereby duplicate class number, values and labels for each field by simply loading a style? (somewhat meta) Am I going around this the wrong way, OR, is there a different face I could use to climb this mountain? I added a comment to  but something strange is happening. The end code reads "); but SO decided to change that to ";);.    I did not add a ; in front of the ).  To further explain what's happening here, the following:  "http://example.com/." http://example.com/. "http://example.com." http://example.com. "http://example.com" http://example.com   renders as: Is it true that $0.999999999\ldots=1$? I'm told by smart people that $$0.999999999\ldots=1$$ and I believe them, but is there a proof that explains why this is? Compactness of $\operatorname{Spec}(A)$ In an exercise in Atiyah-Macdonald it asks to prove that the prime spectrum $\operatorname{Spec}(A)$ of a commutative ring $A$ as a topological space $X$ (with the Zariski Topology) is compact.   Now because the basic open sets $X_f = \{\mathfrak{p} \in \operatorname{Spec} (A) : \{f\} \not\subseteq \mathfrak{p} \}$ form a basis for the Zariski Topology it suffices to consider the case when   $$X = \bigcup_{i \in I} X_{f_i}$$   where $I$ is some index set. Then taking the complement on both sides we get that   $$\emptyset = \bigcap_{i \in I} X_{f_i}^c$$  so there is no prime ideal $\mathfrak{p}$ of $A$ such that all the $f_i$'s are in $\mathfrak{p}$. Now from here I am able to show that the ideal generated by the $f_i$'s is the whole ring as follows. Since there is no prime ideal $\mathfrak{p}$ such that all the $f_i \in \mathfrak{p}$, it is clear that there is no $\mathfrak{p}$ such that $(f_i) \subseteq \mathfrak{p}$ for all $i \in I.$ Taking a sum over all the $i$ then gives $$\sum_{i \in I} (f_i) = (1).$$  Now here's the problem:          How do I show from here that there is an equation of the form $1 = \sum_{i \in J} f_ig_i,$ where $g_i \in A$ and $J$ some finite subset of $I$?       This part has been giving me a headache. I am not sure if the finiteness bit has to do with algebra, topology or the fact that we are dealing with prime ideals.  This is not a homework problem but rather for self-study.  $\textbf{Edit:}$ I have posted my answer below after the discussion with Dylan and Pierre. Android OS without Google Services? Why not to extend the set of natural numbers to make it closed under division by zero? How do I turn on SharePoint App store in SharePoint 2013 What is a "callable"? The  says that public class SomeObject {   public void SomeOperation()   {     lock(this)     {       //Access instance variables     }   } }  is &quot;a problem if the instance can be accessed publicly&quot;. I'm wondering why? Is it because the lock will be held longer than necessary? Or is there some more insidious reason? Using Model to equally distribute points, spatially within known geometry using ArcGIS ModelBuilder? Is it possible to create a model in ArcGIS ModelBuilder where you simply state number of points and an area in the form of a polygon to get the model to try and equally space out the points based on the geometry of the polygon and number of points? In the PHP manual, to show the syntax for functions with optional parameters, they use brackets around each set of dependent optional parameter. For example, for the  function, the manual reads:  string date ( string $format [, int $timestamp = time() ] )   Where $timestamp is an optional parameter, and when left blank it defaults to the  function's return value.  How do you go about creating optional parameters like this when defining a custom function in PHP? How to set up RAID 1? Why does Ubuntu 14.04 LTS use a non-LTS kernel version? I'm writing a sports management simulation game. Like most sport management games, it makes heavy use of statistics.

Update Much thanks for all the input! Number of moves necessary to solve Rubik's cube by pure chance Suppose, random moves are made to solve Rubik's cube. A move consists of a $90$-degree-rotation of some side. The starting position is also random.   What is $E(X)$, where $X$ is the number of moves until the cube is solved ? How many moves must be made, that the probability that the cube is solved, exceeds $99$% ? Is it possible to find out reason of suspension for another user? A user on Stack Overflow was recently temporarily suspended.  Out of curiosity I read through their posts (both questions and answers) and found them to be of decent quality.  They answer far more than they ask (about a 10 to 1 ratio) and always provides lots of sample code in their replies.  They're polite too.  I can't see a reason for suspension.  So, now I'm curious, and maybe I can even learn something from their experience.  Can I find out why they were suspended or is that strictly between the moderator and the user? Determining if an Object is of primitive type I have an Object[] array, and I am trying to find the ones that are primitives. I've tried to use Class.isPrimitive(), but it seems I'm doing something wrong:  int i = 3; Object o = i;  System.out.println(o.getClass().getName() + ", " +                    o.getClass().isPrimitive());   prints java.lang.Integer, false.  Is there a right way or some alternative? How secure would github hosting be for private repositories?
