Blender 2.79 Two objects with identical material settings and no texture. Viewed in Object Mode/Solid View the one on the left has a dark, bluish tint. The two look identical in other views and render with identical colors. But why the different colors in Solid View?  A minor but nagging and annoying nuisance. Much thanks from a newbie.
While rendering a mesh with smooth shading on, I get a dark region/shadow on certain faces. The effect is more evident when smooth shading is applied to a mesh containing ngons, with the ngons turning black when rendered.   The blackening effect is visible in the viewport too.  How can I solve this problem?
What is role-playing, and where do I start? I have been told that roleplaying is great fun. I've looked and looked and it all seems so complicated. Could anyone tell me a good place to start, and what sort of things you end up doing in roleplaying? If you have a statically allocated array, the Visual Studio debugger can easily display all of the array elements.  However, if you have an array allocated dynamically and pointed to by a pointer, it will only display the first element of the array when you click the + to expand it.  Is there an easy way to tell the debugger, show me this data as an array of type Foo and size X? How can I install a package without installing some dependencies?

Given the following class  public class Foo {     public int FooId { get; set; }     public string FooName { get; set; }      public override bool Equals(object obj)     {         Foo fooItem = obj as Foo;          if (fooItem == null)          {            return false;         }          return fooItem.FooId == this.FooId;     }      public override int GetHashCode()     {         // Which is preferred?          return base.GetHashCode();          //return this.FooId.GetHashCode();     } }   I have overridden the Equals method because Foo represent a row for the Foos table.  Which is the preferred method for overriding the GetHashCode?  Why is it important to override GetHashCode? As mentioned on :     For something that can be done so   easily by accident, there should be   the ability to undo mistakes.   I know that I have clicked several times on a comment up-vote without actually wanting to.  I would suggest being able to cancel the up-vote (maybe only for a couple of minutes or even less than a minute, no problem, as long as I can undo a miss-click). Here in the Figure R5=50K. This resistor value is not in the equations to obtain output voltage, and in many tutorials non-inverting input is directly grounded without a resistor. What might be the reason to use it here? Endnotes do not be superscript and add a space Has 'Ubuntu Software' been renamed to 'Snap Store'? I updated Ubuntu last night (sudo apt get update &amp;&amp; sudo apt get upgrade) and to  my surprise this morning I didn't find the 'Ubuntu Software' app and there's a new entry called 'Snap Store' which when opened looks just like the old 'Ubuntu Software' app. So has 'Ubunu Software' been renamed to 'Snap Store'? And if yes, why? I did a dumb thing... I forgot that Ubuntu 10.04 (Lucid Lynx) switched to &nbsp;2 which puts a ton of *.mod files (kernel modules) in /boot/grub. I thought they were soundtrack files put there erroneously, and I moved them. Needless to say, the next reboot was traumatic. I was presented with something I had no memory of ever seeing... a 'grub rescue>' prompt.  With the help of  however, I was able to recover...   I discovered that GRUB rescue does not have 'cd', 'cp' or any other filesystem commands except its own variation of 'ls'. So first I had to find the partition with the /boot directory containing vmlinuz file and other boot image files... (approximation from memory of failed attempts, as well as blank lines for clarity, added 2014-07-10 by docsalvage)    grub rescue&gt;  ls   (hd0,4) (hd0,3) (hd0,2) (hd0,1)    grub rescue&gt;  ls (hd0,4)/boot ... some kind of 'not found' message  grub rescue&gt;  ls (hd0,3)/boot ... some kind of 'not found' message  grub rescue&gt;  ls (hd0,2)/boot ... grub ... initrd.img-2.6.32-33-generic ... vmlinuz-2.6.32-33-generic   I found a /boot directory containing the vmlinuz file vmlinuz-2.6.32-33-generic on partition (hd0,2). Then I manually booted from the 'grub rescue>' prompt. The following commands will...   Set the root to use the /boot directory on partition (hd0,2). Load kernel module linux. Set that module to use the kernel image vmlinuz-2.6.32-33-generic. Set initrd(initialize RAM disk) to use the image initrd.img-2.6.32-33-generic. Boot Linux.  grub rescue&gt;  set root=(hd0,2)/boot   grub rescue&gt;  insmod linux   grub rescue&gt;  linux (hd0,2)/boot/vmlinuz-2.6.32-33-generic root=/dev/sda2 grub rescue&gt;  initrd (hd0,2)/boot/initrd.img-2.6.32-33-generic   grub rescue&gt;  boot    This boots and crashes to the BusyBox prompt which DOES have some rudimentary filesystem commands. Then I moved the *.mod files back to the /boot/grub directory...  busybox&gt;  cd /boot   busybox&gt;  mv mod/* grub busybox&gt;  reboot  The reboot was successful, but that was a lot of work.   Is there an easier way? An electron has no known internal structure, does that imply it has an unknown one? I'm currently reading Alonso and Finn's Electromagnetism book.  It explains that the spin contributes to the magnetic moment and is somewhat comparable to a rotation of the particle around its own axis. It says that the spin of a particle is caused by a certain internal structure, which makes sense in the aforementioned analogy.  Right underneath the paragraph with the explanation of spin, it says "The electron has no known internal structure", but since it does have a spin, does that mean that we know the electron has an internal structure but we just don't know what it is? Size in bytes is significantly less ( half the size) then size in MB in get info window In the get info window it says 387,037,139 bytes which is 387 MB whereas the size on disk is 716.9MB which is 716,900,000 bytes.   du -sh paramgen  result (in MiB) 684M    paramgen  Why is there such a large difference? Assume $T \in \mathbb{R}^{d\times d}$. Let $\rho(T)$ be the spectral radius of $T$ and $\rho \ge 0$. Prove that  $\rho(T) &lt; \rho$ if and only if there exists a $P \succ 0$ satisfying $T^TPT - \rho^2 P \prec 0$.  I can prove the Necessity: If $P = I$, for any $x \in \mathbb{R}^d$,   \begin{equation} x^T T^T P T x - \rho^2 x^T P x = \| Tx \|^2 - \rho^2 \| x\|^2 &lt; 0 \end{equation} so $T^T PT - \rho^2 P \prec 0$  I get stuck in proving the Sufficiency. I'd like to make links to all files in a directory tree. Which means, create the same directory structure and make the links in them to the respective subdirectory in the original dir.  That could be done with   cp -R -s ../foo .   But - that needs an absolute path. So rather  cp -R -s `readlink -e ../foo` `readlink -e .`   I would like the resulting links to be relative.

How to get string with pattern from std::regex in VC++ 2010 See the revision history on , where the  tag was edited in (and subsequently edited out after I started this discussion).  I think, by adding this tag, you're making assumptions about the OP which they could find a little bit offensive.  Particularly with this question, there's no mention of the level of PHP knowledge — it's more a math question than it is a programming question. Someone could be excellent at a particular language whilst not being particularly great at math, so isn't it a bit insulting to make the assumption they're a beginner?

After having opened and used for a while, I found there were moths flying in the house. At the same time, I found worms in the rice. I suspect that the moths are from the worms(rice-size, white body, dark head). I guess but am not sure if they are called rice moths. There were also many little sand-like things in the rice bag, are they the eggs of the rice moths?  Will eating this infested rice pose a health risk?
