I'm trying to texture a capacitor and my top part has a separate material slot. When I assign a new material, the old one is still somehow showing in form of triangles. Why is that? There's nothing in the UV map that would do it.
My problem is simple. I think that the strange deformations on the top are there because there are so many vertices in one face. How do I fix this while maintaining nice topology?  Although I triangulated the top polygon, the problem still persists.

Limit of $L^p$ norm Could someone help me prove that given a finite measure space $(X, \mathcal{M}, \sigma)$ and a measurable function $f:X\to\mathbb{R}$ in $L^\infty$ and some $L^q$, $\displaystyle\lim_{p\to\infty}\|f\|_p=\|f\|_\infty$?    I don't know where to start. I'm trying to get Intel and Nvidia graphics card working together with two monitors. One monitor should use the Intel card and the other the Nvidia card. Of course, I want to use only one keyboard and one mouse to switch between both screens. Bumblebee didn't work for me.  I don't want to use the xserver-xorg-video-all package because I need the Nvidia card for gaming and I can't use only one graphics card because I need one for KVM virtualisation and the other one for my Linux desktop  So I tried to install the drivers and to configure the Xserver manually. The Nvidia driver is working and I get a video output. But I don't get a video output with the Intel card.  I followed   The config files: Energy-Momentum Tensor in QFT vs. GR Matrix reciprocal positive to prove $λ_{max⁡}=n$ Suppose we have $n\times n$ matrix $A$ having only positive elements and satisfying the property $a_{ij}=1/a_{ji}$ (a matrix satisfying this property is called a reciprocal matrix).  If its largest eigenvalue $λ_{max}$ is equal to $n$, then the matrix $A$ satisfies the property (consistency property) $a_{ij}a_{jk}=a_{ik}$ where $i,j,k=1,2,...,n$.    I already found an example of $5\times 5$ reciprocal matrix  to show this condition:  \begin{bmatrix}1&amp;1/2&amp;1&amp;1&amp;1/4\\2&amp;1&amp;2&amp;2&amp;1/2\\1&amp;1/2&amp;1&amp;1&amp;1/4\\1&amp;1/2&amp;1&amp;1&amp;1/4\\4&amp;2&amp;4&amp;4&amp;1\end{bmatrix}  It has simple characteristic equation $λ^5-5λ^4=0$, so the eigenvalues of matrix $A$ are $λ=0$ and $λ=5$ and it's shown that $λ_{max}=n=5$.  Is there anyone can help me to give another positive reciprocal matrix example  that has simple characteristic equation and integer number as its eigenvalues ($4\times 4, 5\times 5$ or $6\times 6$ matrix)? Color change of string delimiter in listings with macro Why do newspaper headlines use strange syntax rules? Newspaper/news article headlines usually have different syntax rules, for example   No copula. North Korea trip 'successful' Past events written in present. Qantas cancels flight out of frozen Heathrow Predictions written with infinitive. Britain's 'crossbow cannibal' to die in jail Very often not in complete sentence. No indefinite/definite articles. Ivory Coast Faction Squeezes UN Force Using a comma instead of "and". Romania, Bulgaria face delay in joining Schengen.   Why these rules and are there any other rules? I know I can choose "Hidden in menus" and never see the devices again when I install a application. But I don't want my old mobile phones display in my account settings anymore. I have sold those phones already and never use them again!  In fact, the list look likes a cemetery in my mind now. ;( How to disconnect selected mesh geometry? I don't know how to disconnect a face from the rest of the mesh in edit mode.  This isn't like pressing P to separate the selection into a completely different object. I just want to select a face and disconnect/rip it away from the rest of the mesh but keep it as a part of the original object.  One way to do it would be to duplicate the face with ShiftD and then delete the original face. But I suspect there is a "native" command for disconnecting selected faces and I would like to learn it. Is there a way to fix a small chip in a wall's paint? I'm not sure exactly with what I've bumped my wall and caused this this:    Is there anything that can be done to fix this without repainting the entire room?  I've been reading around a bit, and not sure exactly what to call this, hence the weird question title.  The paint is a beige-ish colour, not exactly white. The hole is about 2 x 1.5 cm in size.   I've read a bit about spackling paste, though I understand that's for small cracks and holes.  Here are some picture with a better resolution:  and   Unfortunately, I don't have much experience with this sort of thing. Help please.  Also, this is in the UK, so you can tell what stores I might have access to for materials. Is there any bidirectional 5v-3.3v level shifter? Is there any IC that interfaces any 3.3V Input/Output to 5V Output/Input? I need it primarily for an Arduino Due but if there any bidirectional IC that works like that it would be great.  Some people advised me to use the SN74AHC125 and CD4050 ICs, but I don't understand how they work or how to interface with them. Is it OK to borrow a ground wire from a different circuit? I've got a circuit in the basement carrying a handful of outlets.  This circuit has no ground wire.  I want to add a couple of outlets and want them to be grounded.  I may even want gfci outlets on them in the future.  I have no reasonable way of getting a ground wire to the panel but I do have easy access to another circuit that does have a ground wire.  Is it acceptable to borrow or share a ground wire between circuits?  If not, why not?  Both circuits are 20A with 12 AWG wire. How can I (algorithmically) count the number of ways n m-sided dice can add up to a given number? Ignoring accented letters in string comparison I need to compare 2 strings in C# and treat accented letters the same as non-accented letters. For example:  string s1 = "hello"; string s2 = "héllo";  s1.Equals(s2, StringComparison.InvariantCultureIgnoreCase); s1.Equals(s2, StringComparison.OrdinalIgnoreCase);   These 2 strings need to be the same (as far as my application is concerned), but both of these statements evaluate to false. Is there a way in C# to do this? This question has been answered before in many places but I just need some confirmation with my specific setup. I have Linux Mint installed and I just want a fresh Ubuntu 12.04 install to completely replace Mint. It's dual booted with Windows 7 and I want that to remain completely in tact.  Anyway, I'm currently running the Live CD installer. I've said I want to specify my own partitions and I'm at the following screen:     The list at the bottom expanded:     I confused by all the different partitions. Seems like I should just check the box beside sda5. But what about sda6? Do I just leave that alone?  Also just for confirmation, is the "right" way to replace Mint, or should I be deleting it first? How do I disable usb storage? I'm using Ubuntu 12.04 and I want to block usb storage on it. What is the correct way to do this? Changing color of already printed text For making a small quiz in class I am working on a presentation in beamer.  I want to change the color of statements to red (wrong statement) or green (right statement) but only after my class answered the question.  I was searching the internet, but only found the color package, where you apparently can only change the text color before it appears.  Can someone point me into the right direction? ASP.NET Call Code Behind Function From Javascript Can we balance the whitespace above/below headings?
