I have a client who needs their users to run multiple local Windows virtual machines on their laptops. Some users have 3-5 VMs, while others have 10+. I'm aware of the following two routes for licensing guest (desktop) operating systems:   Purchase a retail/FPP license for each VM. Purchase Software Assurance for the host, and leverage the virtualization rights.   The second option works well for up to 4 (well, technically 3) VMs, but beyond that, are there any options aside from simply purchasing retail licenses for the remaining VMs?    I've considering working around this by purchasing a second Windows license for each host and then purchasing software assurance for that license, thus giving an additional 4 VMs via virtualization rights. From the Microsoft perspective, this is no different than if each employee simply had another laptop. Is this a valid strategy?  For context, VDI-like solutions are off the table here, as the users in question are frequently in remote locations with limited internet connectivity. They're also regularly remoting to other systems within those VMs, and I don't want to introduce another hop of latency into that equation.  Also for context, these VMs are, by Microsoft definition, production systems. Any solution involving MSDN or "developer" licenses isn't going to work here.
This is a  about Licensing.    Questions on licensing are off-topic on Server Fault.  If your question has been closed as a duplicate of this question, then this is because we want to help you understand why licence questions are off topic rather than just telling you "it just is". In all likelihood, this question will not address your question directly, it was not meant to.    I have a question regarding software licensing. Can the Server Fault community please help with the following:   How many licenses do I need? Is this licensing configuration valid? What CALs do I need to be properly licensed? Can I run this product in a virtual environment? Can I downgrade this product to an earlier version? Am I entitled to feature X with license Y?
Boot Error - ACPI PCC Probe Failed ACPI PCC Probe Failed is the error that pops up instead of the default GRUB loader after I updated my kernel to 3.19.  I searched around and couldn't find much information except that it is a known error and it is registered in kernel.org's launchpad . My question is, is anyone else facing it?, what are the impacts of this? And if only an update in the future can fix it, any suggestions or safety tips till then?

Let $n&gt;1$ in $\mathbf{Z}$ and let $r(n) = \#\{(a,b)\in \mathbf{Z}^{2};n=a^{2}+b^{2}\}$ Let also $n=n&#39;n&#39;&#39;n&#39;&#39;&#39;$ where $n&#39;,n&#39;&#39;,n&#39;&#39;&#39; \in \mathbf{N}$ and   $p|n&#39; \Longrightarrow p\equiv 1\mod 4 ; p|n&#39;&#39; \Longrightarrow p=2 ; p|n&#39;&#39;&#39; \Longrightarrow p\equiv 3 \mod 4$   for $p\in \mathbf{N}$ prime.   i) Show that if $n&#39;&#39;&#39;$ is not a square, then $r(n)=0$.  ii) Show that if $n&#39;&#39;&#39;$ is a square and $n&#39; = 1$, then $r(n)=4$  iii) Show that if $n&#39;&#39;&#39;$ is a square and $1&lt;n&#39;=p_{1}^{e_{1}}\ddots p_{k}^{e_{k}}$ where $p_{1},...,p_{k}$ are different primes in $\mathbf{N}$ and $e_{1},...,e_{k} \in \mathbf{N}$, then it holds that $r(n)=r(n&#39;)=4(e_{1}+1)\ddots (e_{k}+1)$    I am completely dumbstruck and can't see how to begin (and neither did an older student who took this exam and whom I asked for hints).

Consider a hypothetical situation: In which a time traveler travels in a spaceplane at close to speed of light circling the earth and I get a live telecast of inside of that plane to my television. How time dilation will effect him and what will I observe sitting next to the tv seeing him live. Considering time runs slower at speed of light, will he be looking like a slow motion video? (Or let he also watching live streaming of us at earth, what it will look to him) P.S. I'm not sure if it even makes some sense but if it does kindly explain in logical details. Sorry for the the bad english, I'm not a native speaker. I have two tensors that i must calculate double dot product. matrix A is rank 2  and matrix B is rank 4.

Mapping Russia - Int'l dateline splitting polygon I am having the issue where the International Dateline is splitting a polygon I am working with.  I have a layer of the "Federal Districts" of Russia, and the eastern most federal district is being "cut" by the international dateline.   I currently have the data frame's coordinate system set to Asia Lambert Conformal Conic and this places the two "cut" polygons next to each other (how they should be).  I really need the polygon to not be cut and show as a continuous polygon.   I've researched up and down, tried changing the projection/coordinate system, but with no luck.  I've attached a screenshot of the one multi-part polygon that is being split by the international dateline.  I would like it so that there is no cutting of the polygon, and therefore no boundary line going through the polygon.  I've even tried transforming this multi-part polygon into separate, single-part polygons, then merge them back together, but anytime any part of any polygon crosses this line, it gets cut.  Layout View:    Data View: Include the "People Reached" and "Helpful Flags (count)" data in SEDE I know the new profile design hasn't been updated for  on the network yet, so maybe this is a bit too early.

I would like to upgrade a Toshiba Satellite C55-A5300 laptop so it can be as useful as it can be nowadays. I haven’t needed to use much software for a few years now, and I’m not able to gauge whether a maxed out upgrade of this laptop would be up to running the latest versions of MS Office and Acrobat smoothly. Maybe even run some Photoshop and Lightroom? I want to install the best CPU that will work optimally within the parameters of this laptop, including the laptop’s cooling capabilities. I ultimately want improved performance, but I want the performance to be as smooth as possible. From what I gather the Pentium 2030M is the best processor this motherboard will accept. Am I on the right track? I also plan to fully upgrade the memory and the hard disk speed with respective upgrades. What is the max memory per RAM slot (2 total)? What is the fastest speed of RAM I can use?
