Why pow(10,2)=99 & pow(10,3)=1000?
Is floating point math broken?
What happens when a caster targets an object that looks like a creature with a spell that targets only creatures? Multiple cases in switch statement Is there a way to fall through multiple case statements without stating case value: repeatedly?  I know this works:  switch (value) {    case 1:    case 2:    case 3:       // Do some stuff       break;    case 4:    case 5:    case 6:       // Do some different stuff       break;    default:        // Default stuff       break; }   but I'd like to do something like this:  switch (value) {    case 1,2,3:       // Do something       break;    case 4,5,6:       // Do something       break;    default:       // Do the Default       break; }   Is this syntax I'm thinking of from a different language, or am I missing something? Prove : $$ \text{If } \; x-\lfloor x \rfloor + \frac{1}{x} - \left\lfloor \frac{1}{x} \right\rfloor = 1 \text{, then } x \text{ is irrational.}$$  I think the way to go here is to falsely assume that $x$ is rational, thus having $x=\frac mn$ with $m,n$ integers and go with that, we also know that $x$ with the celling belongs to the integers and that $\frac 1x$ with the celling gotta be a $0$. Still can't prove it. Thank in advance ! Unable to install .NET 3.5 on Windows 8.1 I am trying to install .NET 3.5 to work on few legacy applications and this has been burning my head for past few weeks.

Saving Working Files as PSD or TIFF? I was reading a few articles about how people saved their working files and it got me thinking about my own method. I used to save everything as a PSD, but recently I have started saving my working files as TIFF's. I use Windows, so I don't know if it's different for Apple users but with a PSD, all I can see is that "PSD" icon. But a TIFF file shows up as a normal image (that I can edit), so I found it really great when I have a lot of working files for one project and could just quickly preview it without opening the program.  That being said, I am no expert in which method is better. And I know a lot of people here are pretty seasoned users in all things Adobe, so I was wondering what your two cent on the whole topic is?   Is there really any difference to saving it as a PSD or TIFF? Is there something I should specifically know about saving my files as a TIFF rather than a PSD?

How to view all the Symbolic links,Junction points,Hard links in a Folder using dir? The command dir /a displays a list of all the files,folders in a given location. But it displays the type  for Junction Points as well as Symbolic Links to Folders. Is there any command which will differentiate and tell me which of these  are Junction Points and which are Symbolic links as well as which of the files are hard links ?

Which of the above is/are correct, and why are the others incorrect? Algebraic Proof that $\sum\limits_{i=0}^n \binom{n}{i}=2^n$ I'm well aware of the combinatorial variant of the proof, i.e. noting that each formula is a different representation for the number of subsets of a set of $n$ elements. I'm curious if there's a series of algebraic manipulations that can lead from $\sum\limits_{i=0}^n \binom{n}{i}$ to $2^n$.

How do I hide a process in Task Manager in C#? I have a requirement to hide a process in Task Manager. It is for Intranet scenario. So, everything is legitimate. :)   Please feel free to share any code you have (preferably in C#) or any other techniques or any issues in going with this route.  Update1: Most of the users have admin privileges in order to run some legacy apps. So, one of the suggestion was to hide it in task manager. If there are other approaches to prevent users from killing the process, that would be great.  Update2: Removing the reference to rootkit. Somehow made this post look negative. If I push or hit an object in space will it rotate or move along a straight line?
