I am new with blender program. I have a need to render animation for a inventor model I have.  I got stl. file from inventor which is an assembly. My problem is that I need to color that model before rendering ( In inventor model is painted but when I import it to blender its in default grey).  When I apply coloring in blender it affects whole assembly, which is not good for me, I have some parts that I need to paint in different color.  My question is how to separate those part? As for now I see that assembly as one part and anything I do will affect it whole?  Thank you in advance.
How do you add more than one material to a mesh?   I have tried adding two materials to the object, and then assigning one of the materials to a vertex-group, but I could not find a place to assign it.  I am making a striped bouncy ball that I want to deform, so adding a different material by separating the mesh into different objects would not be ideal.
Broken URL for data.stackexchange.com help page When using data.stackexchange.com I fail to remember if as [post link] is the correct alias to get the url for the post. Luckily the site has an  link. Unfortunately it is now broken. Can this be fixed? What are the differences between Iron Man and War Machine armours ?  In the movies, it seems that they are the same, except the War Machine armour features more heavy weapons. But if they are the same, why wouldn't Tony Stark use the War Machine armour?  Do they have different characteristics (like strength, resistance, flight time...)?  I am looking for answers from the movies and/or the comics. Regex: match everything but specific pattern I'm planning to buy a new Android phone and I'd like to be able to transfer the progress I have made at several games to the new device, so I won't have to play all the levels again from scratch.  I currently have an HTC Desire and will buy an HTC Evo 3D.  There's probably no simple/general solution to this.  But I was wondering if anyone did something similar and could provide some advice (e.g. where to look for files that might hold game progress information). software updater failed to download repository information When I run software updater it says that it failed to download repository information and to check Internet connectivity.

Unicoin Bug: Automining Returns Diminishing I'm using the auto-mining script from one of the meta posts here and it doesn't works!  At first I got steady returns but the returns seem to diminish over time. Using Fiddler I confirmed that the server seems to release less and less coins.  This is unacceptable! I am a loyal customer paying nothing and I demand that my auto-mining script continues to yield returns forever!  If you cannot deliver on that please refund what I have payed for using this site.  Plz advise!    In case you didn't notice: This is a parody of over-demanding, leeching askers on Stack Overflow. OS keyboard shortcuts conflict with apps keyboard shortcuts in GNOME 3 How to prove $\sum_{k=1}^{n}F_k = F_{n+2}-1$ by induction when $F_n$ is the Fibonacci sequence Let $F_n$ be the Fibonacci sequence where  $F_0$ = 0  , $F_1$ = 1 and  $F_n$ = $F_{n-1}$ + $F_{n-2}$.                   I want to prove the following by induction. $$\sum_{k=1}^{n}F_k = F_{n+2}-1$$ Here is what I have so far.  Can anybody tell me if I am right?  Base case = n=1  $F_k$ = 1 = LHS  $F_{1+2}$ - 1 = 2 - 1 = 1 = RHS  Statement is true for n=1.  Assume statement is true for n=i.  $$\sum_{k=1}^{i}F_k = F_{i+2}-1$$  Prove statement is true for n=i+1.  $$\sum_{k=1}^{i+1}F_{k} = F_{((i+1)+2)}-1$$  $F_1$ + $F_2$ +...+ $F_i$ + $F_{i+1}$ = $F_{((i+1)+2)}-1$  $F_{i+2}$ - 1 + $F_{i+1}$ = $F_{((i+1)+2)}-1$  $F_{((i+1)+2)}-1$ = $F_{((i+1)+2)}-1$  Statement holds for n=i+1 Citing papers, that are cited within a paper? I am reading a paper which discussing the change in a specific idea in a field of science over time. I would like to basically summarize the points in the paper but in a smaller fashion by taking some quotes and explaining how they relate to my situation.   For instance, in the paper I am reading the author said "in 2002, Stanley and Miikkulainen [SM02b] argued that the topology of a neural network also affects their functionality" where the tag [SM02b] is a reference to a entry in the author's bibliography.   Is it sufficient to only cite the author of the paper, or do I need to cite both the author of the paper and the author of the paper the author cited in the paper? Can I view a list of my "great comments", perhaps in my profile? I'm a little surprised no one asked this yet, but why isn't it possible to show your comments in descending order of "great comment" votes it has received? You can do this with upvotes on questions and answers, and since I think comments are the third major activity on SO, I'd like to view them. Even if you couldn't order them, it should at least show the number of votes on the activity#comments page of your profile...

I have done it many times (clipping a raster with a polygon layer or by extension) but today I got an error for the first time and I don't know how to solve it. I am always using the same type of raster layers. When running the clipping tool I got the following message:  gdal_translate -of GTiff -ot Byte -projwin 410282.185971 4694950.41162 410783.882475 4694524.96815 -co COMPRESS=DEFLATE -co PREDICTOR=1 -co ZLEVEL=6 -co TFW=YES "C:/Users/FERRAN ALA/Desktop/Justificació Fontanals/QGIS/Topo 1_5000/bt5mv20sd0f283077st1r031.sid" "C:/Users/FERRAN ALA/Desktop/Justificació Fontanals/QGIS/background/image.tif"   GDAL command output:     'ascii' codec can't encode character u'\xf3' in position 201: ordinal not in range(128) See log for more details   Does anybody know what that is?

Find all integer solutions of the equation $a^2+ b^2 + c^2=a^2 b^2$.  This is one of the questions we presented in one session to contest preparation PUTNAM. It turns out that I can't get from the problem. Could someone just give me a hint? (Please, don't give me the answer. Simply, an argument that can help me advance in the problem or theorem might suffice.) Is there a way to get the path for the assembly in which the current code resides?  I do not want the path of the calling assembly, just the one containing the code.   Basically my unit test needs to read some xml test files which are located relative to the  dll.  I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else.  Edit: People seem to be misunderstanding what I'm asking.  My test library is located in say      C:\projects\myapplication\daotests\bin\Debug\daotests.dll   and I would like to get this path:     C:\projects\myapplication\daotests\bin\Debug\   The three suggestions so far fail me when I run from the MbUnit Gui:   Environment.CurrentDirectory gives c:\Program Files\MbUnit System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll System.Reflection.Assembly.GetExecutingAssembly().Location gives the same as the previous. Escape velocity from a rotating black hole Repeating “will” for two verbs with “and” What do the numbers in a man page mean? So, for example, when I type man ls I see LS(1).
