I accidentally emptied the recycle bin in windows 10. How can I restore the Recycle Bin? I didn't set up the file history or backup, so I cannot restore it to the previous version. Is there a good, reliable tool? Or Can I restore it without sw?
What steps can I take to try to recover lost or inaccessible data from any storage device?  Answers:   This applies to any computer storage device, e.g. internal/external hard drives, USB sticks, flash memory. The most important thing is to STOP using it, any type of I/O can ruin your chances of a recovery.     We have separate questions covering common problems with USB flash drives in greater detail:
In older versions of iOS, if I searched for an app with Spotlight, it would tell me which folder the app was in. (E.g., this feature still works on my iPad, which is running iOS 9, but not on my iPod Touch, which is running iOS 11.)  This feature seems to have been removed at some point. When I search for an app under iOS 11 using Spotlight, it will find the app and let me run it, but it doesn't tell me which folder it is in.  How can I find out which folder an app is in now? What is the proper way to extend the Fibonacci numbers to negative numbers? I have a feeling this question is a duplicate, but it's not coming up in "Questions that may already have your answer."  We all know very well that $F(0) = 0$, $F(1) = 1$ and $F(n) = F(n - 2) + F(n - 1)$ for all $n &gt; 1$.  I'm wondering about $n &lt; 0$. My first thought was $F(-n) = -F(n)$, which is appealing from a multiplicative point of view, as it seems to preserve certain identities, like $F(n)^2 = F(n - 1) F(n + 1) - (-1)^n$.  But it doesn't quite make sense from an additive point of view, it doesn't seem to work both "forwards" and "backwards." For example, it would give us $F(-1) + F(0) = -1 \neq F(1)$.  How do we extend $F(n)$ to negative $n$ so as to maintain both the related identities and the basic defining identity? How did Dumbledore gain the loyalty of Fawkes? How did Dumbledore find Fawkes. Did Dumbledore have Fawkes even when working as a Transfiguration teacher or acquired it after having Headmaster position. They both have a very strong bond between them. When did Dumbledore gain this. Update: Dumbledore says that Ollivander wrote to him when Harry's wand was purchased; if Dumbledore did not have Fawkes before 1938, he would not know about the two feathers being in the wands, so Fawkes and Dumbledore must have met and bonded before 1938  “My wand's feather came from Fawkes?” Harry said, amazed. &quot;Yes,” said Dumbledore. “Mr. Ollivander wrote to tell me you had bought the second wand, the moment you left his shop four years ago.” -Harry Potter and the Goblet Of Fire, Chapter 36-The Parting Of the Ways.  Update 2: JKR says that Dumbledore was the only owner of Fawkes. So it is to be believed that Fawkes was a wild Phoenix before its bonding with Dumbledore.  Peter Humphreys for BBC Newsround: Who did Fawkes previously belong to and will he play a vital role in the next book? JK Rowling: I am not going to answer about the role in the next books, which probably gives you a big clue, and he has never been owned by anyone but Dumbledore. You will notice that when Harry goes back in the Pensieve in this book, Fawkes is never there, and ­­ no, I am sorry, not in this book, I take that back. When Harry has previously seen the study with a different headmaster he saw it with Dippet and Fawkes was not there then. Fawkes is Dumbledore's possession, not a Hogwarts possession. Regarding the `book`, `report`, and `article` document classes: what are the main differences? Problem Currently, I am playing on a server where hoppers transport items at the rate of 64 items a second, and this has proved very difficult to build a sorter for. I'm not at all proficient in Redstone building but have tried building basic sorters and ones that I have found on YouTube and I haven't gotten anything to work. Solution Hopefully one of you is really good at Redstone and can help me design a sorter that can work under these conditions. (I need the sorter that can sort items while I AFK kill witches with a looting 47 sword P.S. most of the problem is with the sorter itself because no items will stay in the sorter hopper (bc the whole stack goes into the chest so the hopper doesn't have anything to go off of to sort) so any solution to that would be helpful as well. Normal distribution tail probability inequality I am trying to show that $$P(X&gt;t)\leq \frac{1}{2}e^\frac{-t^2}{2}$$ for $t&gt;0$ where $X$ is a standard normal random variable.  Perhaps this is simple.  I have been starting with  $$ \int_{t}^{\infty} \frac{1}{\sqrt{2\pi}} e^\frac{-x^2}{2}dx \leq \int_{t}^{\infty}\frac{x}{t}\frac{1}{\sqrt{2\pi}}e^\frac{-x^2}{2}dx = \frac{1}{t\sqrt{2\pi}}e^\frac{-t^2}{2}$$  but this is not what I want...I am looking for a much stronger inequality.   Any help in the direction of getting the $1/2$? What server control panels are available for Ubuntu Server? As a dedicated Ubuntu server or as a VPS, I am looking for a web control panel, something like cPanel which is something like a web administrator for a server.  I have not used any on Linux since I do everything through the terminal, but still want to know what I can use in the case I have to recommend Ubuntu Server with such an application installed. ,  and 1 still show the old bar. 1 See When should I add another answer? I have been member of SO for 4 months. I have a question regarding some functionality. Whenever I give an answer to a question, there is functionality given Add Another Answer. I can comment on my answer at any time and also able to edit answer. Then   Why this functionality given on SO to add another answer?  When should I add another answer?  Why there is requirement of multiple answers? What is limit of adding answers to single question? Well, this question has been puzzling me for kinda long time, many people believe that orbiting astronauts feel weightless because they are "beyond the pull of Earth's gravity"...How far from the Earth would a spacecraft have to travel to be truly beyond the Earth's gravitational influence? If a spacecraft were really unaffected by Earth's gravity would it remain n orbit? If so, what is the real reason for weightlessness in orbit? Is it permissible to use somebody else's words (without quotations) to describe a concept once their work is cited? Quite often one comes across a really succinct and precise explanation of a concept. I'm wondering if it is permissible to use this explanation verbatim, if the source work is cited in your paper (next to the explanation)? What's in question here is at most 3 sentences. I have a set of values $x$ and $y$ which are theoretically related exponentially:  $y = ax^b$  One way to obtain the coefficients is by applying natural logarithms in both sides and fitting a linear model:  &gt; fit &lt;- lm(log(y)~log(x)) &gt; a &lt;- exp(fit$coefficients[1]) &gt; b &lt;- fit$coefficients[2]   Another way to obtain this is using a nonlinear regression, given a theoretical set of start values:  &gt; fit &lt;- nls(y~a*x^b, start=c(a=50, b=1.3))   My tests show better and more theory-related results if I apply the second algorithm. However, I would like to know the statistical meaning and implications of each method.  Which of them is better? Formerly List of all badges with full descriptions.  What are badge name's requirements? Why didn't I get badge name ? Which badges can I earn multiple times?    Jump to:                    Note: Some badges are awarded based on score. The term score means the total number of upvotes minus the total number of downvotes.  Any badge with a *** next to it is one of 20 badges that count towards the  displayed on a moderator candidate in an election. The candidate score is a total of 40 points: the first 20 are awarded based on the user's rep divided by 1000 and rounded down; the second 20 represents the total number of unique badges earned of the 20 that count. Note that if the same badge is earned multiple times, it will only count once towards the candidate score.  Any badge with a &quot;(retired)&quot; next to it is no longer awarded, but is retained by users who previously earned them. See  for more info on what it means for a badge to be retired.

Assume that you have any two real numbers $a$ and $b$, and $1\leq k &lt;\infty$, $k \in \mathbb{R}$.  How would you prove the inequality $|a+b|^k \leq 2^{k-1} (|a|^k+|b|^k)$? A Basic Question about Gravity, Inertia or Momentum or something along those lines In case, if I get a multiple-entry Schengen visa in one of the embassies in Ukraine, Kyiv - should my first trip be to the country which issued the visa?  Any there any requirements of this sort? Does this condition vary depending on embassy which issued the visa?  What are the possible consequences on not visiting that country first? Does it somehow depend on country where the embassy is (i.e. non-Schengen and not EU members)? Is there a (Unix) shell script to format JSON in human-readable form?  Basically, I want it to transform the following:  { "foo": "lorem", "bar": "ipsum" }   ... into something like this:  {     "foo": "lorem",     "bar": "ipsum" } Do you ever need to specify 'javascript:' in an onclick? AFAIK, you never need to specify the protocol in an onclick:  onclick="javascript:myFunction()" Bad  onclick="myFunction()" Good  Today I noticed in  on Google Anallytics that they are using it:  &lt;a href="http://www.example.com" onClick="javascript: pageTracker._trackPageview('/outgoing/example.com');"&gt;   Is this example just plain wrong, or is there ever a reason to specify javascript: in anything other than a href? Latexmk and the location of Asymptote's generated files I am trying out Asymptote with latexmk and I would like to automate the interaction.  Consider the following latex document test.tex:  \documentclass{minimal} \usepackage{asymptote} \def\asydir{asymptote}  \begin{document}  Testing Asymptote:  \begin{asy} settings.outformat = "pdf"; unitsize(2cm); draw((0,0) -- (1,0)); \end{asy}  \end{document}   In my latexmkrc I have the  for Asymptote integration:  sub asy {return system("asy -o asymptote/ \"$_[0]\"");} add_cus_dep("asy","eps",0,"asy"); add_cus_dep("asy","pdf",0,"asy"); add_cus_dep("asy","tex",0,"asy");   Running latexmk -pdf test.tex generates test.pdf in the current folder and test-1.asy and test-1.pdf in the asymptote folder -- but only if   I manually created the asymptote folder prior to running latexmk. The folder specification in the latex document (\def\asydir{asymptote}) and latexmkrc (-o asymptote/) are identical.   I would like latexmk to read asydir from the main tex file, create the directory if it does not exist and run asy with the read output folder.  Is this possible?
