One of my answers to a question was "edited" by another user.  The "editing" consisted in inserting a hyphen in one of the words I had used, and "replacing" some other words with the identical spellings.  What should I do in such circumstances?
has been edited by .   , see revisions 3 to 4.   Now what he did is totally inexplicable to me, as a matter of fact he destroyed the answer. The new version is neither syntactically valid nor does it make any sense.  Still, the edit got "peer-reviewed" and nodded off.  Is there any way to deal with these kinds of things, other than sighing heavily and rolling back the edit?  Rhetorical side question: Could this be a side-effect of people grinding for reviewer badges?

Cannot install Ubuntu in VirtualBox due to "this kernel requires an x86-64 CPU, but only detects an i686 CPU, unable to boot" error Show that $n^3-n$ is divisible by $6$ using induction As homework, I have to prove that     $\forall n \in \mathbb{N}: n^3-n$ is divisible by 6   I used induction  1) basis: $A(0): 0^3-0 = 6x$ , $x \in \mathbb{N}_0$ // the 6x states that the result is a multiple of 6, right?  2) requirement: $A(n):n^3-n=6x$  3) statement: $A(n+1): (n+1)^3-(n+1)=6x$  4) step: $n^3-n+(n+1)^3-n=6x+(n+1)^3-n$  So when I resolve that I do get the equation: $n^3-n=6x$ so the statement is true for $\forall n \in \mathbb{N}$  Did I do something wrong or is it that simple? CSV API for Java Can anyone recommend a simple API that will allow me to use read a CSV input file, do some simple transformations, and then write it.

Bidirectional 1 to 1 Dictionary in C# I am looking for a generic, bidirectional 1 to 1 Dictionary class in C# (2), ie. a BiDictionaryOneToOne&lt;T, S&gt; which is guaranteed to only contain one of each value and key (up to RefEquals anyway), and which can be searched using either key or value. Anyone know of one, or should I just implement it myself? I can't believe that I'm the first person to need this...  There is a BiDictionary in the answers to , but it is not for unique elements (and also does not implement RemoveByFirst(T t) or RemoveBySecond(S s)).   Thanks!

Radius of circumscribed circle of triangle as function of the sides Given the length ot the sides $a , b$ and $c$  of $ \triangle ABC$.  What is the length of the radius of the circumcribed circle?  After some formula substitution I came to the monster formula:  $$ \frac {a b c}{\sqrt{2a^2b^2+2a^2c^2+2b^2c^2-a^4-b^4-c^4}} $$  Can this formula be simplified? I prefer to use bm package to bold math. However, I noticed that when used with eulervm, this gives inconsistent results for ‘&lt;’ and ‘>’ characters.

Xubuntu or Lubuntu on a Mac mini? My Mac mini doesn't have sufficient hardware for Ubuntu 11.04 (specifically Unity I think), and so I have to use the classic environment, which is fine, but it seems to run slower on 11.04 (I'm upgrading now to 11.10).  However, I heard  that if it runs slow I should use Xubuntu or Lubuntu.   So my question is:    What is the best way to upgrade from Ubuntu 11.10 to Xubuntu or Lubuntu and which one would be better for a late 2005 model Mac Mini PPC? Sorting seach results in Android app The issue is how can user sort questions for a particular search query?   For example, I would want to search questions for  and want to see newest questions first.  Right now If we write any query in Search Questions... input box then users are not able to select sorting options as search questions input box takes whole width of the screen and sorting options box gets hidden.  I have also tried to select sorting options first and then search for  but still its showing questions without considering sorting option I have selected.
