Hidden files on USB drive I have a lot of necessary files and documents on USB Drive. when i connect it to other PC it gets to as hidden and .EXE. Are there any way to make  them un hidden and cleaned?
How can I recursively clear the "Hidden" file flag on Windows Vista? A friend's computer was recently infected with a virus.  I hope the virus has been removed successfully. But, it appears that the virus set the "Hidden" flag on most directories and files on the system.   What's the most convenient way to clear this flag from selected directories and their contents?
I'm considering taking a loan on my 401k in order to pay off and close 2 credit cards.  I have approximately 30 years until I consider retiring.  The amount of the loan will be $1700 which is less then 20% of my current 401k balance.  I will continue to put 9% of my paycheck into a Roth 401k, and my employer matches 9%.  The loan will be paid back at 3.25% (to myself) and does have $183 in fees.  There are 2 cards I will pay off and close if I follow through with this plan.  One card is 17.9% interest with roughly a $650 balance.  The other is 23% (ish) with roughly a $1,025 balance.  Both of these cards do have an annual fee associated with them, I used them to rebuild my credit and have a newer, lower interest, no fee card that I will keep active for emergencies.  Would it be advantageous for me to pay off these two credit cards and cancel them with a 401k loan? Close Vote Review Audits are too obvious The other day, I got an obviously good question in a Close Vote Review.  Even if I didn't read the question,  is a bit of a giveaway.  Today I got one where   Also, on sites other than SO (where I understand the queues are huge), the number of reviews needed is often low enough (single digits) that you usually notice when you get an extra one.

How do I change the default file manager back to Nautilus? A while back, I set my default file manager to Nemo. I like it a lot, but it constantly crashes. I remember editing a text file to set it as default, but I forgot which file it was. How do I switch back to the Nautilus file manager? Editing question title creates whole new question and other question list problems I'm a mathematician interested in abstract QFT.  I'm trying to undersand why, under certain (all?) circumstances, we must have $T^2 = -1$ rather than $T^2 = +1$, where $T$ is the time reversal operator.  I understand from the Wikipedia article that requiring that energy stay positive forces $T$ to be represented by an anti-unitary operator.  But I don't see how this forces $T^2=-1$.  (Or maybe it doesn't force it, it merely allows it?)  Here's another version of my question.  There are two distinct double covers of the Lie group $O(n)$ which restrict to the familiar $Spin(n)\to SO(n)$ cover on $SO(n)$; they are called $Pin_+(n)$ and $Pin_-(n)$.  If $R\in O(n)$ is a reflection and $\tilde{R}\in Pin_\pm(n)$ covers $R$, then $\tilde{R}^2 = \pm 1$.  So saying that $T^2=-1$ means we are in $Pin_-$ rather than $Pin_+$.  (I'm assuming Euclidean signature here.)  My question (version 2): Under what circumstances are we forced to use $Pin_-$ rather than $Pin_+$ here?  (I posted a  on physics.stackexchange.com last week, but there were no replies.)    EDIT: Thanks to the half-integer spin hint in the comments below, I was able to do a more effective web search.  If I understand correctly, Kramer's theorem says that for even-dimensional (half integer spin) representations of the Spin group, $T$ must satisfy $T^2=-1$, while for the odd-dimensional representations (integer spin), we have $T^2=1$.  I guess at this point it becomes a straightforward question in representation theory: Given an irreducible representation of $Spin(n)$, we can ask whether it is possible to extend it to $Pin_-(n)$ (or $Pin_+(n)$) so that the lifted reflections $\tilde R$ (e.g. $T$) act as an anti-unitary operator. Toy Line (Production) Run I am not sure about the meaning of this:          Transformers: Generation 1 (also known as Generation One or G1) was a children's toy line that ran from 1984 to 1991 and was produced by Hasbro.     Would the following rewrite be better?

Suppose I define a new theorem "Theorem" and declare that its counter should be reset whenever the subsection counter is incremented or reset:  \newtheorem{theorem}{Theorem}[subsection]   At some point in my (article) document I start a new \section (say, section 2) without starting a \subsection. I expect the first theorem in this section to be numbered with "2.0.1" (which may be considered bad style). However, the theorem is numbered "2.0.2".  Is this "by design" (technically, I didn't start a new \subsection) or a bug? Moreover, what would be a proper workaround? (Such a workaround should not involve manually resetting the theorem counter, and it should work for whatever theorem type I may define in addition to "Theorem".)  \documentclass{article}  \newtheorem{theorem}{Theorem}[subsection]  \begin{document}  \section{bla}  \subsection{blubb}  \begin{theorem} Some text. \end{theorem}  \subsection{foo}  \begin{theorem} Some text. \end{theorem}  \section{bar}  \begin{theorem} Some text. \end{theorem}  \end{document}   EDIT: In response to Seamus' comment: The unexpected counter value also occurs with amsthm and ntheorem. How to get a cross-origin resource sharing (CORS) post request working How do I check if an element is hidden in jQuery?

Upon realizing it is a sarcophagus, he decides to sacrifice himself (I think by disconnecting his air) and exist in it for eternity along with the original creature.
