I am not sure what the hell is going on, neither I know where to ask. For me it looks like phenomenon, but it often ends up being completely explanatory.    I've discovered that if I place my SAMSUNG Galaxy S4 mini smartphone somewhere in the right of the DELL Inspiron (n series) touchpad, it turns off the monitor. I made sure the mobile devise has nothing turned on (such as wifi, bluetooth etc)    DETAILS: It turns off the laptop's monitor when it keeps vertical proximity to the hotspot(s) not larger than an inch.    Who has any idea what this is about ?
If I put my phone on my notebook's left corner, it shuts down. Can anybody give me reliable explanation as to why this is happening??
I updated to TeXLive 2017 and couldn't get newlfm.cls to work without errors.  Here is a minimal example:  \documentclass{newlfm} \begin{document} \begin{newlfm} \end{newlfm} \end{document}   LaTex is throwing undefined control sequence errors on \fancy@reset, \f@ncyolh, and \f@ncyorh.  What causes the errors?  What am I missing? Solve $\lim_{x\to 0} \frac{\sin x-x}{x^3}$ Community isn't on ~15 sites! I have an armature set up, but the bones aren't moving the mesh properly  The mesh and armature:    The vertex group of the bone I am going to move:    As you can see, the circled region doesn't belong to the vertex group. But, when I move the bone look what happens:    That part of the mesh has moved with the bone.. Why? Alphabetically display the items in itemize Collection of clopen sets form a base for a countable completely regular space I have $X$ as a countable, Tychonoff space, and I want to show that the collection of clopen subset of $X$ form a base for the topology on $X$.  Can I first just define a base $\mathscr{B}$ of X, let $x\in X$ and $E \subset X$ is closed such that $x\notin E$. So $x\in X-E$, which is open.   I also noticed that the interval $[0,1]$ is uncountable. Can I define a function $f: X\to [0,1]$, then f is onto. Do I need to show that $f$ continuous next? A short story about finding an inhabitable planet and meeting aliens So the story goes, humans in a spaceship search for an inhabitable planet, being surprised they found none in the vicinity of Earth. They find one, and it seems uninhabited. At the same time are observed by the aliens, who go down on the planet to meet them. The aliens sit them down and tell them a story about war and conflict that ruled the galaxy, and how all the sentient races in the galaxy got together and got rid of the race that tried to conquer all by blowing up their planets.  In the end you realise man is this terrible conqueror the aliens are talking about. Let $ P(x)=x^8 - x^7 +x^2 -x +15 $, Descartes' Rule of Signs tells us that the polynomial has 4 positive real roots , but if we group the terms as $$ P(x)= x(x-1)(x^6+1) +15 $$ we find that $ P(x) $ does not have any positive roots.  Where did I err ? MWE:  \documentclass{article}  \usepackage{listings}  \begin{document}  IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII hardware/software  \end{document}   This results in this output:    If \usepackage{listings} is commented out, the hyphenation rules return to normal:    And just to note, in the actual environment I'm working in, it will also hyphenate between hard•ware, while with listings enabled, it hyphenates hardware/•software, as in the first image:    Two questions:   Why is this happening? Is there a way to disable this? I don't really want this behaviour just because I'm typing code occasionally in a document. Do users get notifications when @ was edited in I always wondered if users get notified about comments were their name was edited in afterwards.  Example:  I write a comment     See this link here   then I edit it to     @someuser: See this link here   Does the user get notified now? I'm trying to run the remove_doubles edit command on multiple selected objects. This is kinda what I got so far...  import bpy   class remDoubles(bpy.types.Operator):     """Remove Doubles on multiple objects"""     bl_label = "Remove Multiple Doubles"     bl_idname = "object.remove_doubles_multi"     bl_options = {'REGISTER', 'UNDO'}      @classmethod     def poll(cls, context):         return len(context.selected_objects) &gt; 0      def execute(self, context):          scene = bpy.context.scene         sel = context.selected_objects          for obj in sel:             scene.objects.active = obj              #do something here             print(obj.name)             bpy.ops.mesh.remove_doubles()          return {"FINISHED"}  myobject = remDoubles()  myobject.execute()   My knowledge about classes isn't too great, please help.  My code needs some work, it just errors out giving a  'TypeError: bpy_struct.new(type): expected a single argument'  But what i intend doing is run through each object applying the remove doubles command for each.

Move iTunes folder outside Music folder iTunes by default stores its settings, the iTunes Library.itl file, and the music library audio tracks, inside the \Users\username\Music\iTunes folder.  I don't want my Music folder polluted with program settings, especially because I'm synchronizing that folder on the cloud. Via the settings panel I can only change the path of the audio tracks, but the settings remain in the default position.  Is there a way to completely move the iTunes folder to another path?  PS: I've looked at the answers to , but the focus there is on moving the media library only, not the whole iTunes directory. TikZ: Intersection of two lines what is the easiest way to determine the intersection of two lines?

I found a nautilus script I would like to use. How do I install it? How can I find the method that called the current method? When logging in C#, how can I learn the name of the method that called the current method? I know all about System.Reflection.MethodBase.GetCurrentMethod(), but I want to go one step beneath this in the stack trace. I've considered parsing the stack trace, but I am hoping to find a cleaner more explicit way, something like Assembly.GetCallingAssembly() but for methods. How to get Total Pupulation From Tables In Sqlserver? Possible cardinality of power sets What cardinals can provably not occur as the cardinality of a power set? I know that $\mathbb N$ and natural numbers that are not powers of two are such cardinals. What else is out there? Another way to evaluate $\int\frac{\cos5x+\cos4x}{1-2\cos3x}{dx}$? What I've done is this:$$\int\dfrac{\cos5x+\cos4x}{1-2\cos3x}{dx}$$ $$\int \dfrac{\sin 3x}{\sin 3x}\left[\dfrac{\cos5x+\cos4x}{1-2\cos3x}\right]{dx}$$ $$\dfrac {1}{2}\int\dfrac{\sin 8x -\sin 2x +\sin 7x -\sin x}{\sin 3x - \sin 6x}$$ $$-\dfrac {1}{2}\int\dfrac{ \sin \frac{7x}{2} +\sin \frac{5x}{2} } {\sin \frac{3x}{2} }$$ $$-\int\dfrac{ \sin {3x}\cos \frac{x}{2} } {\sin \frac{3x}{2} }$$ $$-\int\dfrac{2\sin \frac{3x}{2} \cos \frac{3x}{2}\cos \frac{x}{2} } {\sin \frac{3x}{2} }$$ $$-\int {2\cos \frac{3x}{2}\cos \frac{x}{2} }$$ $$ -\left(\frac{\sin 2x}{2} +\sin x \right) +c $$ Is there any other way to do so ? Is it possible to do it by substitution ?
