System freezes/unresponsive/unusable when copying large file to USB How do I restore .bat files association with the system (make them run when double-clicked)? N circles in the plane Which of the following sentences is/are incorrect? ("Permit" vs. "allow" vs. "let") Which of the following sentences is/are incorrect? Why?   The visa permits you to study for two months. My father would never allow me to study English Let me to go. You're hurting me.   This is question from an English learning book. All the sentences seem right to me. Do you know which one is incorrect and why? In 1D why are vectors, such as, e.g., velocity $v$ and acceleration $a$, not written with a vector arrow? In my textbook instantaneous velocity and acceleration are wrote only as $v$ and $a$ in the chapter of One dimensional motion. Instead, in two dimensional motion chapter they are written with the "arrow" symbol upon them, $\vec{v}$ and $\vec{a}$.  Why if they are both vectors they don't have an arrow in that particular chapter? I just can't get it. Why aren’t my villagers breeding? I’ve got one villager up 7 blocks surrounded with 6 doors. On ground level I have villagers who are supposed to breed. They are willing, their inventories are full of potatoes, and I’ve been sitting here for hours.  Hearts are popping up above their heads but nothing happens. I am playing on Xbox One. Do I need internet/3G to use GPS? I have a Samsung Galaxy S2 that has some problems with the GPS: If I use internet my navigation works but when I turn the 3G off, GPS does not work.  Do I need internet/3G to use GPS? I wanted to change my own password (as an admin) so I did the following command:  sudo passwd   and then it prompted for a password but when I tryed to relog, my password was not changed. I'm now wondering what password did I changed since it did prompted me to enter a password but I'm not sure what password did it changed exactly.  I know that if I do sudo passwd &lt;MY_USER&gt; it works, I'm just wondering without a user what happens.  Thank you what are the meanings of &quot;treated observation&quot; and &quot;non-treated observation&quot; in this context ?  Further, propensity score matching is a more robust method of matching that quantitative accounting researchers frequently use (Rosenbaum &amp; Rubin, 1983). With this technique, the researcher first estimates a logit or probit regression with the treatment effect as the dependent variable (i.e., S&amp;P 500 membership, continuing with our earlier example) and independent variables that are known determinants of the treatment (possibly economic performance, firm size, age, industry, etc. in our example). From this first-stage regression, the researcher obtains propensity scores. 6 The researcher then matches each treated observation to a non-treated observation based on the distance between their propensity scores (i.e., those observations with the closest propensity scores are matched). 7 Hoi et al. (2013) utilize propensity score matching in their study that links irresponsible CSR activities with tax aggressiveness. They first generate predicted propensity scores for each firm-year using a model of the determinants of a firm engaging in a high level of negative, irresponsible CSR activity. Then, they match a treatment firm (one with a high level of negative CSR activities) to a non-treatment firm (one with a low level of, or no, negative CSR activities) by matching observations with the closest propensity scores. Hoi et al. (2013) then re- test the relation between negative CSR activities and tax aggressiveness using this matched sample. These matching techniques help mitigate the researcher’s potential failure to consider certain firm characteristics that differ between treatment and non-treatment firms (Dhaliwal et al., 2012). How to disable battery charging? From the pmset man page:     POWER SOURCE ARGUMENTS      -g with a 'batt' or 'ps' argument will show the state of all attached power sources.      […] Certain Apple battery calibration tools may temporarily disable   battery charging, even though your Apple portable is plugged into AC   power.      Such tools will never surprise you with this behavior; you will know   it's happening. This state will be reflected in an additional line of   output to 'batt' or 'ps' readings, including the pid of the app   inducing this behavior.       'ChargeInhibit':    1432    So, does any piece of publicly available software exist to force the battery not to charge? How do I test for a mob, with a given name, in a certain location? I want to testfor a sheep, by the name of Lamb, in a certain location using coordinates.  I have already tried this:  testfor @e[x=999,y=80,z=-1034,type=Sheep,name=Lamb]   But it doesn't work. I have also tried:  testfor @e[x=999,y=80,z=-1034,type=Sheep]   But it says it found a sheep whether or not there is actually a sheep in that location. "Temporarily unreachable" when using fetch as Googlebot from Webmasters Tools The page I'm trying to fetch is public.  The server logs show no request.  Google reports that any page on my site is "Temporarily unreachable". It won't even fetch the verification file, a static HTML file that was successfully used to verify with the webmaster tool application itself.   My site is running on the .  What is causing this? Remove items from one list in another Delete Everything(the rest of the text) after a specific string I recently purchased an ASUS K55A. Like all Windows 8 machines, it come with a UEFI feature called Secure Boot. This basically makes sure that the laptop won't load anything other than the Windows 8 OEM version that came with it.  However the Asus UEFI allows for me to disable Secure Boot, and therefore I should be able to revert to Windows 7, Linux, etc. (drivers may or may not be supported). When I insert my Linux Mint boot disc and try to boot from it, though, nothing happens. There isn't even a boot priority list in the UEFI settings (I can provide screenshots later). It just says "Windows 8 Bootloader" and also on the other tab it says "WINDOWS 8 BOOT OVERRIDE".  Has anybody purchased a Windows 8 machine and successfully installed Windows 7 or Linux on it? Retrieve the position (X,Y) of an HTML element relative to the browser window I want to know how to get the X and Y position of HTML elements such as img and div in JavaScript relative to the browser window. 'find' utility does not output all files when using wildcards Improve file-info visibility in Finder's preview pane I find the file information in the preview pane in column view is far more useful than the thumbnail.  I wish I did not have to continually resize the Finder window or scroll the preview pane to see the info I'm looking for.  As you can see below, the useful info is hidden in default  size  of Finder's new window under the preview options like rotate etc.        Is there a way to do any of these to achieve the said goal (listed in order of decreasing likelihood!):   reduce the size of the preview "thumbnail" covered by black here,  reduce the amount of whitespace(grey here) around the preview "thumbnail" (only significant for landscape thumbnails), remove the preview "thumbnail" altogether,  reorder the content of the preview column(bring file info up and send thumbnail down)?    includes the options:   resizing the Finder in every new window (which is labor intensive). Using View menu> Show Preview Options to turn off Quick Actions (which must be done for each file-type, and only reveals a small amount of file info). I'm new to inequalities in mathematical induction and don't know how to proceed further. So far I was able to do this:  $V(1): 1≤1 \text{  true}$  $V(n): n!≤((n+1)/2)^n$  $V(n+1): (n+1)!≤((n+2)/2)^{(n+1)}$  and I've got : $(((n+1)/2)^n)\cdot(n+1)≤((n+2)/2)^{(n+1)}$ $((n+1)^n)n(n+1)≤((n+2)^n)((n/2)+1)$ Fire Adaptive Domain rendering like a solid cube When I render I see a solid cube which is Adaptive domain. But it shouldn't show up. I feel like I missed something. It is my first time simulating fire.  Candle with a solid domain blocking the fire    The material seems to be plugged in to the volume already :/  Node setup
