Should all event handlers added with on() be removed in the scope $destroy event handler
Do we need to unbind event listeners in directives when angular starts to destroy?
I have installed Ubuntu on, but now I am trying to install NVIDIA CUDA Toolkit for the GPU. When I install it, it says that there is no driver found, so I have tried to install the driver, but I don't know why after installation, the system not coming up. Maybe it is because of the wrong version of the driver.   When I tried to detect the driver version using sudo lshw -C display , it showed this information:    But here it doesn't say that what is the product name of the driver, and also when I go Software &amp; Updates -> Additional Drivers, then it says NVIDIA Corporation: Unknown.    What should I do? One of the pertinent questions about many body systems that causes me much wonder is why the solar system is so stable for billions of years. I came across the idea of "resonance" and albeit an useful concept, it hardly explains the long stability of the solar system. Normally an N body problem with inverse square mutual interaction is an example of a chaotic system. Is there any real progress about this stability issue? Change owner of internal hard drive partition from root to user I have a number of drives internal and external. Some are partitioned. Most mount automatically at boot (all did at one point).    One partition is owned by root and therefore does not mount automatically. I know how to mount it as root.   I do not know how to take ownership of that partition as user X. I have tried changing permissions using the gui in Nautilus as root. They are not accepted and immediately revert.  The partition is NTFS. The other parition on that drive is owned by me as user and mounts automatically Multiple authors in one row with refmark, multiple affiliations in separated columns in another row I wonder how we can list author names in the following format in LaTeX.   I have 5 authors with 3 different affiliations. I am trying to list all author names with refmark in one row, and 3 affiliations with refmark in another row, but each in one separated column. It should look like this:          author1{1} author2{2} author3{1} author4{2} author5{3}            {1}department      {2}department        {3}department               school              school              school               email                email              email   I did saw some papers that have the above format, but cannot search for any guideline. IEEE guideline suggests another way to list authors, but sadly it does not look that neat          author1{1} author2{2} author3{1} author4{2} author5{3}                         {1} department, school                               email                         {2} department, school                               email                         {3} department, school                               email A man condemned to serve his sentence in other times The Riemann zeta function $ζ(s)$ is defined for all complex numbers $s ≠ 1$ with a simple pole at $s = 1$. It has zeros at the negative even integers, i.e., at $s = −2, −4, −6, ...$.   My question: How one can obtain these roots. A new search engine for Stack Exchange There are a few examples of pairs of words ending with -ee/-er like employee and employer or advisee and adviser. What I was curious about is if there was any rule that would describe the relationship of the objects in a pair like this and situations when it's appropriate to create a counterpart for a given word.   I'll give you an example. It's relatively common in the computer programming world to see the word dragee, which describes an object that is being dragged with a mouse. I understand that this is a relatively new word and could not be found in any dictionary (I've tried). Is that acceptable to make up words like this one or is it just bad English?

I need to prevent the machine from going to sleep because that pauses the Dropbox sync  I've been using  to keep the computer awake, but it also keeps the computer unlocked which is insecure.  I need a method to keep my Mac awake (so that Dropbox can sync overnight) but also locked (so no one can read my email). It'd be great if this method also turned off the screen (to preserve power), but honestly that's not even 100% necessary. Is there geometric or visual (but rigorous) proof for the equation of hyperbola whose foci are on the $x$-axis using only the traditional definition of hyperbola: a hyperbola is a set of points such that the difference of distances from each point to focus is constant $(|r_1 - r_2| = 2a)$?  Also, can you maybe geometrically explain asymptotes of hyperbola (why do they exist)? How to resolve ambiguous column names when retrieving results? Why is it true that every finite-dimensional inner product space is a Hilbert space? A Hilbert space is, by definition, a complete inner product space. If $(V,|.|)$ is finite dimensional inner product space of dimension $n$ then it is (topologically) isomorphic to $\mathbb{R}^n$ which is of course complete. My instinct here is to say "and therefore, $V$ is also a Hilbert space". I'm not sure about this step however since completeness depends on the norm and the norm depends on the selected inner product (assuming the induced norm $||x|| = (x | x)^{1/2}$ is used). So, must we place some condition on the inner product or is the topological isomorphism between $\mathbb{R}^n$ enough to guarantee that V is Hilbert? I made a bootable Windows 7 USB using UNetbootin, and when I try to boot from the bootable USB and select the Default boot menu entry, it gets stuck at the UNetbootin boot menu and it keeps repeating an Automatic boot in 10 seconds... message in an endless countdown loop. Selecting Press [Tab] to edit options and editing the options has no effect. When I go back to the boot menu, it keeps repeating the same countdown loop.   I've tried redoing the UNetbootin extraction, but I still have the same issue. I am currently running a Dungeons and Dragons 4 campaign for a group of 9 players.  Whittling the group down to a more manageable size is not really an option since they are all family.  When we do combat it takes forever even if I have one player help me and allow them to go 2 at a time.  When we do story based adventure there are 2-3 players that do most of the talking and the others twiddle their thumbs.  I've tried encounters with many foes, encounters with only a few tough foes, dialog only encounters, social puzzle encounters, everything I can think of.  What else can I try to get this group more engaged?
