My laptop is overheating after installing Ubuntu GNOME16.04 LTS. It's hanging because of overheating. I think that my laptop's cooling system is not working properly and I am unable to find what to do.  sensors:    HTOP:

Why is my host name wrong at the Terminal prompt when connected to a public WiFi network? For three days straight, I have connected to the public WiFi network at my local library. Each day, I have seen a different prompt in Terminal. Here are some of the prompts I've seen:  zp-pc:~ russell$ mary-pc:~ russell$ normob05:~ russell$   I have check under System Preferences -> Sharing, and my computer name is "Russell's Mac". Also, I set the DHCP Client ID to "RUSSMAC" under System Preferences -> Network -> Advanced -> TCP/IP, but I still see the random host names at the Terminal prompt.  Why is my computer name changing every day? I'm looking to create a virtual printer that passes data to my .NET application. I want to then create an installer that installs both the printer and the .NET application.  It would we really nice to be able to write it all in C#, but I have a feeling that this will require a printer driver to be written is unmanaged code.  Does anyone know of a fairly clean tutorial or example of how to do this? Why didn't Sauron become invisible while wearing the One Ring? I'm curious as to why Sauron is the only being/person shown wearing the One Ring who does not become invisible?   Isildur, Gollum, Bilbo, Frodo, and Samwise all become invisible while wearing the One Ring.  Why didn't Sauron become invisible while wearing the one ring?  I became interested after reading Pearsonartphoto's question asking what effect wearing the One Ring would have had on . Centering polygon on specific coordinates using QGIS I need to place a set of polygons onto a set of points, so that each polygon is centered on its corresponding point. How do I do that? In MapInfo I can just manually edit the coordinates of the center, but there does not seem to be an equivalent in QGIS. What tool can I use to manage the configuration of my Windows Server environments I help manage environments for an application that uses cloud-based Windows server VMs. The application stack consists of Windows Server 2008 and Windows Server 2012, SQL Server 2008, IIS, and SharePoint 2010. I have several environments Dev/Test/Stage/Prod. I am looking for a way to do configuration management of those environments to make sure any environmental changes are applied in a consisent way and there is a way to verify that no changes have been made to one environment that have not been made to other environments.  I have been reading up on Puppet, Chef, etc and I like the idea of doing delcarative configuration management. What is a good method or tool to use to help manage the configuration of these environments. I know a little  about SCCM but it is too expensive for this particular situation although I would still be interested in knowing if it has the capabiltiy to do those things. Why is the edit button disabled? Is it correct to omit preposition before date? What do I need in a camera to take non-blurry photos of a fast-moving child? I'm a mom who is obsessed with taking photos of my now 2 year old daughter.  I currently have a Nikon j1 which I like, but I find the shutter speed is still a bit slow and when you're trying to take photos of a speedy little girl, I end up with a lot of blurry images.  So I'm looking for a camera with a very fast shutter speed that will allow me to take good photos of a very fast moving child.  Also that can take photos in low light. I've been looking at the canon eos rebel but I'm not sure. Would like it to be able to take videos as well. Any advice? I've installed Ubuntu 13.04 two times on my PC. Each on a different partition. I would like to delete the one which I'm not using. How would I do that? What is special about square numbers here? plist or sqlite Blender Nodes in Editor doesn't show preview Image I have a small problem with my blender lately. I want to make some compositing with my compositing nodes but the problem is, blender won't show me the preview Image. I have a Screenshot for you guys.    The preview Image itself is enabled, but it just won't show.  Thanks for your help in advance!  -Marten The MSDN documentation on  describes 3 contradicting rules for how the method should work.     If two objects of the same type represent the same value, the hash function must return the same constant value for either object. For the best performance, a hash function must generate a random distribution for all input. The hash function must return exactly the same value regardless of any changes that are made to the object.   Rules 1 &amp; 3 are contradictory to me.  Does Object.GetHashCode() return a unique number based on the value of an object, or the reference to the object. If I override the method I can choose what to use, but I'd like to know what is used internally if anyone knows. Proving $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements I am attempting to prove what the title says, that $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements.  I have already proven that for any field $K$ and polynomial $f(x)$ in $K[x]$, $K[x]/\langle f(x)\rangle$ is a field if and only if $f(x)$ is irreducible in $K[x]$. So I know that $\mathbb{F}_p/\langle f(x)\rangle$ is a field for sure. Where I'm lost is figuring out how to know for sure that there are $p^n$ elements. It's fairly clear if $n\in\{ 0 ,1\}$, but I don't think induction is going to help.  I know from a proposition in class that since $F_p = \mathbb{Z}/\langle p\rangle$ and $F_p = \mathbb{Z}/\langle p\rangle$ is an integral domain, $F_p[x] = (\mathbb{Z}/\langle p\rangle)[x] = (\mathbb{Z}[x])/(\langle p\rangle[x])$, but I'm not sure whether or not that's helpful information.

In Windows I used command-line clipboard copy-and-paste utilities...      pclip.exe and gclip.exe     These were UnixUtils ports for Windows (but they only handled plain text). There were a couple of other native Windows utilities which could write/extract any format.    I've looked for something similar in Synaptic Package Manager, but I can't find anything.    Is there something there, that I've missed? ... or maybe this is available in Bash scripting?    The type of utility I'd like will be able to read/write via std-in/std-out or file-in/file-out, and handle Unicode, Rich Text Format, picture, etc. clipboard formats...    NB: I'm not after a clipboard manager. Install software from packages, or build it from source? There is a command l available on my machine which appears to do nothing.  which l also produces no output. Is this a real command, and does it actually do anything? Can I use Ctrl+Shift for changing languages? I can't set this hotkey for changing keyboard languages.
