I would like to know which are the benefits of using this program in relation with the architecture. I would like to know if it is a tool from the architects to know something about lights or something like that.  I'm Adrián from Spain, and I'm discovering Blender now because I'm doing a kind of tesis about this program.  Thanks :)
My interest in Blender comes from wanting to use it to model physical structures and produce architectural drawings; what I have so far is really impressive, but there doesn't seem to be too much information about my particular interest.   Are there any (Blender-) resources that would be particularly useful for architects? E.g. packages of standard 'elements' like windows, doors, roofs or whatever, or perhaps a discussion group specifically for architects?
Algorithm for minimization of sum of squares in regression packages Plotting two variables as lines using ggplot2 on the same graph R raster: masking a raster by polygon also remove cells partially covered? I want to mask out a raster based on the values of a polygon: i.e., set to NA all values of the raster that are not covered by the polygons. However, it seems that raster::mask() masks out cells (i.e. set them to NA) even if they are partially covered?  This is similar to the question: , but unlike crop(), mask() does not have the snap="out" option.   Check: here the right point of the triangle touches a cell, yet that cells is masked out.   library(raster) library(sp)  r &lt;- raster(xmn=1, xmx=5, ymn=1, ymx=5, nrows=4, ncols=4) r[] &lt;- 1:length(r)  Sr1 = Polygon(cbind(c(2,4,4,1,2),c(2,3,5,4,2))) Sr2 = Polygon(cbind(c(4.1,4,2),c(2,3,2)))  SpP = SpatialPolygons(list(Polygons(list(Sr1), "s1"), Polygons(list(Sr2), "s2")), 1:2)  plot(mask(r, SpP)) plot(SpP,  add=TRUE) Add folder name to beginning of filename In the , if I select any site in the site switcher it will be set as Stack Overflow or some random site in the drop down list's selected site name.

I have a failure to transfer my game from one HDD to another, and one PC to another. I copied the entire Skyrim folder from one HDD to another. And told where to find it also. Steam did a huge check of my HDD.  But it ended up downloading most of the files anyway. It took a week to download Dawnguard, Hearthfire, and Dragonborn files along with my Hi-Res textures.  I did ask about it in chat. But I feel this could help me or somebody else.  This is the screen I am looking at after transferring my entire hard drive to to new one. Steam downloaded my games, including Skyrim even though my Skyrim data folder had all the data files for Dawnguard, Hearthfire, Hi-Res and Dragonborn.  I have my copied files and have got rid of everything not steam related. I just have my DLCs and they include my hires files.  This is what it looks like.    But I still get this :     What could be causing this? How can I rectify? And in future when one is migrating to a new PC, how can this be avoided?  EDIT::::::::::::::::: Removed everything : Here is how it looks :  Still the prompt as before Steam Error 15  (Side Note : I transferred all my Origin games just by copy/pasting. This really is not nice.)    EDIT 2 :::::::::::::::::::::  And one more EDIT  I tried getting game cache up to speed, but this is prompt I am getting. But I played the game, it was working, I could pick out my character and all, and escape from Helgen.  EDITED 3 :::::::::::::::::  How does one transfer a Steam game?

Prevent pdflatex from writing a bunch of files If I create just a basic hello.tex file an compile it using   pdflatex hello.tex   The pdflatex program is creating a plethora of file which is a little annoying. Currently it writes all those files about which I really don't care:  hello.aux, hello.log, hello.nav, hello.out, hello.snm, hello.toc   Is there a way to tell pdflatex to only write hello.pdf if the build is successful ? If not, can I specify the output directory of those files ? Maybe I could just write them in /tmp. What is the accepted/most commonly used way to manipulate dynamic (with all dimensions not known until runtime) multi-dimensional arrays in C and/or C++.  I'm trying to find the cleanest way to accomplish what this Java code does:  public static void main(String[] args){  Scanner sc=new Scanner(System.in);  int rows=sc.nextInt();  int cols=sc.nextInt();  int[][] data=new int[rows][cols];  manipulate(data); }  public static void manipulate(int[][] data){    for(int i=0;i&lt;data.length;i++)    for(int j=0;j&lt;data[0].length.j++){          System.out.print(data[i][j]);           }     }   (reads from std_in just to clarify that dimensions aren't known until runtime).  Edit:I noticed that this question is pretty popular even though it's pretty old.  I don't actually agree with the top voted answer.   I think the best choice for C is to use a single-dimensional array as Guge said below "You can alloc rowscolssizeof(int) and access it by table[row*cols+col].".  There is a number of choices with C++, if you really like boost or stl then the answers below might be preferable, but the simplest and probably fastest choice is to use a single dimensional array as in C.  Another viable choice in C and C++ if you want the [][] syntax is lillq's answer down at the bottom is manually building the array with lots of malloc's. What's the canonical way to check for type in Python? What is the best way to check whether a given object is of a given type? How about checking whether the object inherits from a given type?  Let's say I have an object o. How do I check whether it's a str? One Object won't Show up in Final Render even though it shows up in the Preview Render I have a model of a building with a sidewalk around it.  Both show up when I switch to rendering mode in both Blender Render and Cycles Render mode.  But:  when I hit F12 for a final proper render, the building shows up -- but the sidewalk doesn't.    I've checked the normals and I thought the normals seemed pointed in the right direction.  I've set the Clipping on the Camera to a high number.  I removed all the materials from the sidewalk and added a new material-- the problem persists.  I've exported the blend as an FBX file and the Sidewalk shows up fine in Unity.  Just in final renders, it doesn't show up.    Here is a blend file: .  I tried to destroy everything unrelated to the issue and label things in a clear way.    Thanks. Wire nut several wires together I need a wire nut large enough so that I can bundle seven 14 gauge neutral wires together. I am trying to splice it so I can connect it to my new smart wifi leviton light switch.  I don't know which wire nut size to buy.  The boxes say for example: minimum 2#14 gauge - maximum 2#10 gauge.   My question is, can you tell me which wing nut or brand or size to buy so I can group 7 neutral wires together? None of the sizing chart on the box says the exact words of "ok to bundle seven #14 gauge wires together.  Which one should I use? Scala final vs val for concurrency visibility Why does `\texttt` repeat and shrink my equation? When I use \texttt with the caret symbol in an amsmath equation environment, I get a very weird result.

MWE:  \documentclass{article} \usepackage{amsmath}  \begin{document}  \begin{equation*}     \texttt{y^o} \end{equation*}  \end{document}   Compiling this document with pdflatex produces the following result:    The same result occurs even if I remove the o character.
