The plus minus sign after take a root of terms
Is $\sqrt{64}$ considered $8$? or is it $8,-8$?
Would a Jedi (Sith) clone be force-full or force-less Just seen a picture of Vader Force-choking a trooper. And then I started wondering: what if they had cloned a Sith (or a Jedi). Would the clones have the Force? Specifically, would they have the same Force as the original? For example, in this text:     Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc eu tellus vel nunc pretium lacinia. Proin sed lorem. Cras sed ipsum. Nunc a libero quis risus sollicitudin imperdiet.   I want to match the word after 'ipsum'. Auto-sort column Google Spreadsheet on incoming Google Form response How can I get the Google Spreadsheet to automatically order the incoming form responses alphabetically (2nd column)?   I know how to do this manually or by going in and editing a cell, but cannot get it to do this as an onevent for incoming response. root folder access via gui I'm new to linux and the terminal. As I learn how to use the terminal to navigate through directories, I like to use the gui file explorer to mirror my terminal navigation. The icons and file extension info in the gui file explorer help me figure out what everything is. However, I can't access the root folder via the gui, I can only access it via the terminal. Is there a way to enable access to the root folder outside of the terminal? , Laser Interferometer Gravitational-Wave Observatory, is a large-scale physics experiment aiming to directly detect gravitational waves. The device measures the phase shift laser beams.  If I understand this well, the measurement assumes that a suitable gravitational wave reduces and prolongs one of the tubes and the extension will take effect in the phase-shifting laser beams.  But I think if there's a gravitational wave that passes through it, it will affect everything, even the laser beam. This means that when the wave lengthens or shortens the tube, it also lengthens or shortens the wavelength of the laser beam.  In my opinion, therefore, this device does not work. Or am I wrong? Changing sides in tennis This  says:      A player has to win six games, and at least two more than the foe, to claim a tennis match. Players switch sides after every odd game, as in the first, third and fifth games, and so on. Players also switch sides at the end of a set if they're playing an odd number of games.   So, you start, 1-0, and change sides. If the game ends 6-0, 6-2 or 6-4 (or an even number of games), you play the first game of the new set, change sides, and you are back to the previous rule.  But what if a player wins 6-1 or 6-3? You win the set, then change sides. Now, you play a new set, do you change again at 1-0 (therefore after having played just one game), or wait until the 1-1 or 2-0, therefore now changing after an even number of games in the second set? QGIS creating a fixed distance buffer over selected areas not the entire layer what im doing is making a fixed distance buffer and it's working splendidly but i need the buffer to be created over certain selected areas not the entire layer, and at the creation wizard is only offers the the option of selecting the entire layer, and i need some areas within that layer to have a different buffer and some none at all.  is there a way around that? How can a file be copied? Active vs passive voice with inanimate object as the subject I have asked the  in ELL Stackexchange forum. There all the answers and comments I received was really helpful, but still I was looking for something more. So I have decided to ask this same question here also.   I have seen some sentences like this -         The film was announced to be released on this coming Friday.   The film was announced to release on this coming Friday.      Both the sentences are used, and I know they are interchangeable and does bear the same meaning. But I have some doubt about the second sentence - why is it "to release", when the film cant release itself.   Some other sentences of similar structure that arises my confusion -         The product sells well.   The book reads well.   The glass broke.      The sentences are understandable, but in each of the sentences the subjects can't perform any job, as they all are inanimate object. The verbs are active, but they acts like they are used as passive.  Now my question is how to decide which verb to use this way and which not? I cannot find these strings using Transifex:      (name hidden from user)       Regards,   {site name} Moderation Team          There is  and it seems like this string does not work ok (it is translated and approved, but, unfortunately, not rendered on the site).   All of the strings are taken from Moderator Private Messages interface.   Could you please fix it? I'm really new to Mac OSX and UNIX based systems. I wanted to run a few Windows games on my Mac Mini so I started installing Wine and MacPorts. I think the installs are correct, but when I type sudo port install wine I see a not found error in my terminal. I tried other basic commands like say and clear and all of them return the same not found error. My research shows that my PATH might be incorrectly set, but it lacks steps I can implement. Specifically, I ran this command: echo $PATH and it returned:  /opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin  I'm a complete newbie to mac and have no idea where .bash_profile or any of those files are. My skills let me install Xcode and the Command Line tools for Xcode and I sense I need to level up on path management. At this point I need help managing my dot files and changing my path to fix these specific errors on Mountain Lion. What are my next steps? What does $(command) & do? I saw the following syntax in a bash script:   &gt;$(command) &amp;   I know that the ampersand &amp; at the end makes a command run in the background, but I have never seen it in combination with the dollar sign plus the brackets around the command.

In the faq of meta sites you can read something like the following:     Voting here works a bit differently   from other Stack Exchange sites. On   Meta Stack Overflow, voting is used to   express agreement or disagreement, not   to point out a lack of quality or   helpfulness. Please don't be concerned   if you receive downvotes – members of   the community may simply disagree with   your bug, feature request, support   issue, or the nature of the   discussion.   My question is: If votes works differently on meta sites how does that of accepting answers work?  Take for instance a question on a meta site that is meant for the community to discuss some issue. What does it mean if the question is accepted? Accepting an answer is up to the author of the question so it cannot be a sign of what answer the community concludes from the discussion. It could mean that the discussion is over but that should be up to the community and not the author of the question. Is it so that accepting an answer for a discussion question on a meta site does not have a particular function? Cannot add PPA: 'ppa:~darklin20/ubuntu/bomi'.

Is there a number $n$ such that there are exactly 1 million abelian groups of order $n$?   Can anyone please explain. I would yes because numbers are infinitive, and so any number n can be expressed as a direct product of cyclic groups of order n.  Can anyone please help  me understand.  Thank you. Resize multiple layers around their respective anchor points I have 50 or so layers (imported images as smart objects) that I would like to scale down, while they stay in place. Is there a way of doing this? I know After Effects has, is there a similar Scale property in photoshop? When a new tag is created, should there be some kind of notification to the user?  This could serve a dual purpose:   To make the user check that this tag is really required.  Is it spelt right? Might there be a more appropriate tag to use instead? - See  To promote the creation of tag wikis.   These are both beneficial to the site.  Making users think twice about their tags reduces the amount of retagging edits that are needed and reduces noise.  Promoting tag wikis means that more new tags would come with explainations, making them more user-friendly for others.  Creating a new tag is a privilidge earned at 1500 reputation.  Hopefully the user has gained a feel for the ethos of SO by this point, and is either enjoying being a contributer or is mainly asking good, well recieved questions.  The user is probably also wanting to contribute to the site further (even if just to gain reputation), and so it makes sense to me that there should be a gentle push towards taking a little bit of time to write a short wiki for the tag you just created.  By no means should this be mandatory, and the precise format of this gentle push is more in the scope of UX guys to think up, but I wanted to see how people felt about some kind of discreet notification.  I thought of two forms this notification could take:  Option 1 - at the time of tagging      Option 2 - after posting      Update: Raphael has suggested in the comments that this could be implemented as a 10K user tool.  While I think that's a good idea on its own, I don't think it should be used instead.  I think that encouraging users with less than 10K to complete wikis for their own tags is likely to get some wikis written because there is a sense of ownership over your own tag, and by giving it a wiki you are giving it a better start in life. As with a child, users will want to equip their tag with the tools it will need to survive in the big wide world. I found a feature request at  but it doesn't seem easy to get a column view with Nautilus while with Mac OS X it's a default feature.  Have I missed something or is this not currently possible?
