FastBoot recovery failed: partition 'recovery' not support flash How long do you get to use a UK standard visitor visa from time of issue or is it valid for entry indefinite I am going to apply for a standard visitor visa for my girlfriend to enter UK. If it is issued how soon does it have to be used after issue, ie. validity until time of entry? Why should the minimal class be avoided? number of vertices in a self-complemntary graph Problem: Prove that the number of vertices of a self-complementary graph must be congruent to 0 or 1 modulo 4. I think my starting point would be that P4 and C5 are self-complementary and proceed by induction by adding P4s. I established the first step in a previous problem, but I need help on the induction step. i.e. proving that adjoining P4 will indeed yield a self-complementary graph. I got pretty confused at that question... Can anyone help me understand this question better and/or drop some hints please? Thank you! If $A$ and $B$ are nonempty sets, prove that $A \times B = B \times A$ if and only if $A = B$.   Proving the first direction of this is easy. That is, if $A = B$ then it is obvious that $A^2 = A^2$. I am wondering how to prove the other direction now. Maybe proving it by contradiction will be easier than directly. Resizing an image in a post? What are C++ functors and their uses?

Looking for a classic sci-fi short story about a boy who discovers pods growing in a field For years, I've been looking for a short story about a boy who discovers alien pods in a field that are growing replacement people. If I remember right, he sees the pod creature eat his mother and then become her, and no one believes him. The story ends with him going in to see his dad, one of the few real people left until that point, and seeing something (an empty pod maybe) that lets him know his dad has been taken and he's next. I'm thinking that the title was something like Father Figure, but I may be remembering wrong.  The story was part of several collections of classic science fiction stories that we had on our bookcase when I was growing up, so I'm guessing that the story could be from the 70's or any time earlier. Adding dynamic text to layout from attribute table with Data Driven Pages I was trying to figure out how to use dynamic text from an attribute table in a collection of Data Driven Pages in ArcGIS 10.   I've looked in the help files, but can't find anything on dynamic text from attribute tables. $x^4 + y^4 = z^2$ $x, y, z \in \mathbb{N}$,    $\gcd(x, y) = 1$  prove that $x^4 + y^4 = z^2$ has no solutions.  It is true even without $\gcd(x, y) = 1$, but it is easy to see that  $\gcd(x, y)$ must be $1$ Is there a way to turn off an external Apple Cinema Display remotely and continue to use the computer? Here's the situation: I often access my Mac Pro remotely using Screen Sharing and sometimes TeamViewer. The problem is that when I do this, everything I'm doing can be seen by those near the physical computer. It also uses a considerable amount unnecessary power to have the displays on but not actually being used.  Is there a way to turn them off and not just blank if possible, while still using Screen Sharing or TeamViewer Free?
