Does $P(A\cap B) + P(A\cap B^c) = P(A)$? Is it possible to make LaTeX mark overfull boxes in the output? 30" monitor has black border around desktop I have been using a 24" monitor with my macbook pro early 2011 connected via a mini display port to DVI adaptor.  I recently received an HP Z30i 30" monitor.  When I connect to it with an mini display port to display port adaptor, although it displays at the monitors native 2560x1600 resolution, the mac is scaling the desktop display down so as to leave a 1cm or so black border around the desktop.  The mac reports using a resolution of 2560x1600 and the display reports this also.   This makes the display blurry as single pixels become sub pixels.   The display looks like the same effect as having "under scan" turned on when using an HDMI cable at 1080p.  I thought that maybe there was a hardware or display problem, but when I boot off a previous system partition from a different hard-drive using the same OS (10.8.5) release, the monitor set up works perfectly.  This proves the OS release, display and the hardware, so I'm thinking that there must be a preferences problem with my current setup.  Perhaps the under scan setting is somehow being applied to this display when it's not using HDMI?  I've tried deleting /Library/Preferences/com.apple.windowserver.plist, ~/Library/Preferences/ByHost/com.apple.windowserver.HostNumber.plist and rebooting but no results.   The scaling is applied before the login screen and logging in as a different user has the same problem.  Any ideas?  It's driving me nuts, I've got this nice 30" screen and I can't use it! Find all $n\in\mathbb{N}$ so that there exist $x,y,z\in \mathbb{N}$ that solve:   $$(x+y+z)^2=nxyz$$   I tried to attack it finding solutions, but all the solutions doesn't seem to have something in common. For example:  $$ (x,y,z,n)=(1,1,1,9)$$ $$ (x,y,z,n)=(1,2,3,6)$$ $$ (x,y,z,n)=(1,4,5,5)$$ $$ (x,y,z,n)=(2,2,4,4)$$ $$ (x,y,z,n)=(8,8,16,1)$$  I was trying to solve this problem, but someone told me that a hint to solve it is using Vieta Jumping. I don't know how to use Vieta Jumping, so can anyone help me to understand how to apply Vieta Jumping and solve the problem? If $a,b$ are the roots of the equation $2 x^2 -3 x +1 = 0$, find an equation whose roots are $a/(2b +3)$, $b/(2a +3)$ If $a,b$ are the roots of the equation $2 x^2 -3 x +1 = 0$, find an equation whose roots are $a/(2b +3)$, $b/(2a +3)$   I was practicing quadratic equation questions online but I am stuck on this question.  I found the values of roots $a= 1$, $b= 1/2$ Stop terminal auto executing when pasting a command Right, this is a slightly annoying feature because something this happens, and other times it doesn't, very odd.  I paste a command into the terminal with a view to tweaking its arguments, and sometimes it executes the second I paste it. Sometimes it doesn't.  This ranges from embarrassing ( posting nonsensical comments on an IRC ) to dangerous.   How can I shut this feature off for good? I never, never, never want the terminal to auto execute when I paste to it. How to add tags to files in Windows 7 so that they appear in search results In Windows 7, I want to add tags to my files (PDF, Word, Images etc) so that they appear directly in the search results, regardless of their content, title etc.    shows how to search by tag, but it does not tell how to add a tag in any file.  In the long term, I'm planning to add such tags programmatically as well. Taking back turns, and forgotten privileges Choosing variables to include in a multiple linear regression model I am currently working to build a model using a multiple linear regression. After fiddling around with my model, I am unsure how to best determine which variables to keep and which to remove.  My model started with 10 predictors for the DV. When using all 10 predictors, four were considered significant. If I remove only some of the obviously-incorrect predictors, some of my predictors that were not initially significant become significant. Which leads me to my question: How does one go about determining which predictors to include in their model? It seemed to me you should run the model once with all predictors, remove those that are not significant, and then rerun. But if removing only some of those predictors makes others significant, I am left wondering if I am taking the wrong approach to all this.  I believe that  thread is similar to my question, but I am unsure I am interpreting the discussion correctly. Perhaps this is more of an experimental design topic, but maybe someone has some experience they can share. How to access the system tray using the keyboard? Is there a way I can access the system tray items using the keyboard in Windows XP? Inconsistency in display of animated avatars It has been discussed previously that animated avatars are disliked because they cause a distraction from the content. However, currently animated avatars are not treated consistently.   On desktop, animated avatars are displayed as a still image, both in posts and on the profile page. On mobile, animated avatars are displayed as a still image in posts, but animated on the profile page.   I'm tagging this  because I'm guessing one of these two is unintended. Either avatars should animate on the profile page on both desktop and mobile, or on neither. (I sincerely hope that we are all agreed there should be no animation of avatars in posts.)  Example animated profile    This appears to animate on mobile, and show a still image on desktop (for myself and for other users who have tried).    I'd also like to hear arguments for and against animating only on the profile page, but the main purpose of this post is to clear up the inconsistency. external variable in awk Subdivision surface modifier creates pinching at corners I've only been 3D modelling for a few days now, so this may just be a newbie mistake:  However, because this model is for use in a game I am trying to stay away from proximity loops for performance reasons. Instead, I have used edge creases to maintain the structure of the model. It has led to certain vertices not being affected by the subsurf modifier, causing undesirable lighting at high subsurf levels.  Manually moving each point in a bit seems kind of sloppy but I'm not too sure what the best way to go about this is.  If any more information is needed I'll give what I can, thanks in advance :) List questions: Community Wiki? If we remove the square in the upper right corner of a $8\times 8$ chessboard.  The question is: Is it possible to cover the entire remaining area, with $1\times 3$ chocolate bars? (they can be laid on the chessboard vertically and horizontally aswell)  For the answer: We know that there will be $63$ squares left on the chessboard, of which $32$ are white and $31$ are black, since the one in the upper right corner was black. $63$ is divisible by $3$, so it could be possible to cover the area, but that doesn't prove that an arrangement exists to do it. I'm not sure how to continue and am seeking help. Thanks. What's this I hear about First Edition Unix being restored? that the source code of First Edition Unix had been restored from tapes.  The response was amazement and a request for more information.  What have people done?  Who did it?  When?  And how? I know that there is a very similar question, but I'm not interested in highlighting. What I'm looking for is some tool in Linux to edit pdf files. I've tried pdfedit which did the work for me, but if freezes after a few edits. I've tried this tool under Ubuntu 9.10 and under KDE Fedora 14 and the same thing happens. I've tried Okular but the notations are too big to fill out exercises from pdf workbooks.    Is there any tool that suits this job? I don't care whether it is open source or I have to pay a reasonable price for it. I know that python has a len() function that is used to determine the size of a string, but I was wondering why it's not a method of the string object.  Update  Ok, I realized I was embarrassingly mistaken. __len__() is actually a method of a string object. It just seems weird to see object oriented code in Python using the len function on string objects. Furthermore, it's also weird to see __len__ as the name instead of just len. We've tried this a few times. First time we used an old ceramic container and it started sheding on the inside and ruined it. Next time we used a new metal garbage can with one of those super sized 10 gallon zip lock bags as a liner. It went rank very quickly. This could have been due to our packing though. Before we get into this again, what is you recommendation for a good container? I hate the thought of plastics but it seems it might just be the best choice as long as it's made for food storage. Why is the method executed immediately when I use setTimeout?
