My phone (Note3) has a large amount of ram, but there are always lots of applications that can run back ground which can easily consume  more than 90% of your memory.  It's really annoying to manually clean them time to time.  Can I set it up so that if I click home button then I will end current app completely?
When my phone starts up there are several application/services running in the background that I would rather not.  And when I press the Home button while using an app, that app usually goes into the background without exiting.  How can I stop these apps from running?
What techniques can be used to define a class in JavaScript, and what are their trade-offs? I prefer to use OOP in large scale projects like the one I'm working on right now. I need to create several classes in JavaScript but, if I'm not mistaken, there are at least a couple of ways to go about doing that. What would be the syntax and why would it be done in that way?  I would like to avoid using third-party libraries - at least at first. Looking for other answers, I found the article  that discusses object-oriented programming in JavaScript. Is there a better way to do inheritance? The shop is five minutes away.     According to the dictionary, away is an adverb. An adverb modifies a verb. In the above example, what word does away modify? Why is away not an adjective?       The shop is five meters tall.     tall is an adjective in the second example. It modifies five meters (does it?). So why is away an adverb? How to get from Gatwick airport to Paddington? What's the most straightforward way to get from Gatwick airport to Paddington station in London using public transport?   I'm mostly interested in travel time &amp; general smoothness of the trip (e.g. buying just one ticket for the whole trip would be nice). Price is a secondary concern. Mapping building to only one grid which contains more than half of its area using QGIS? Two similar limit problems I have two limit problems which are quite similar, so I've put them both into this post.   $((4^{10}+2^{n})^{\frac{1}{n}})$ $((3n^{2}+n)^{\frac{1}{n}})$   Attempt:  For 1, I'm not sure if this is permissible. I know that $\lim_{n \to \infty}(x^{n}+y^{n})^{\frac{1}{n}} = \max\{x,y\}$. Obviously $4^{10}$ is a constant so it's not quite in the same form, but I believe it is still okay to use this result, and so the limit is $2$.  For 2, I've got $((3n^{2}+n)^{\frac{1}{n}}) = (n(3n+1)^{\frac{1}{n}})$, but then I'm not too sure how to proceed.   I also thought of taking the log and proceeding that way, however in the notes I'm learning from they haven't covered l'hopital yet, so I'm trying to not use it.  Thanks. Recently, I am trying to create 3D models for my own game project. However, when I do some researches on game models, I come up with the term - game-ready models and I could not find any clear definition online. Could anyone tell me about what exactly is game-ready models and how to know if my 3D models (created by Blender mainly) is suitable for games.  From what I know by far, quad topology is preferred in Blender. However, for most of the game engine, triangle topology is preferred (Please correct me if I am wrong). Does it mean I have to manually change the models in Blender from quad topology to triangle topology before importing to the game engine?  Thanks for any helps. Sudoers blacklist 2.8 mesh select mode hotkey changed The hotkey for mesh select mode (vertex, edge, face) while in edit mode Ctrl + Tab has been reassigned in 2.8.

POSIX compliant way to redirect stdout and stderr to a file I am trying to write a script which is POSIX compliant, so it can run on any *nix system (Debian, Fedora, CentOS, AIX, Arch... ALL of them). When it comes to redirection, I am rather confused on what is supported by POSIX and what is not.  If I redirect ls -l file missingfile &amp;&gt; out.txt this works perfectly in bash. The line from stderr complaining that missingfile doesn't exist, and the permissions output from file, are both in out.txt. However, I believe this is only working because these shells support more than just POSIX standard operators. Upon researching this question I've come across conflicting answers.  , for example, seems to imply that &amp;&gt;, &gt;&amp;, &gt;&gt;&amp; and &amp;&gt;&gt; are non-standard operations. However,  explicitly states that some-program &gt; some_file 2&gt;&amp;1 is POSIX compliant. Does this mean that the &gt;&amp; operator (using digits for stderr &amp; stdout) is POSIX compliant whereas using &amp;&gt; to auto redirect both stderr and stdout to a file is not POSIX compliant? Or are both &amp;&gt; and &gt;&amp; not POSIX compliant / POSIX compliant (one of these two people are wrong)?  I considered just avoiding the &amp; sign completely and using ls -l file missingfile &gt;out.txt 2&gt;out.txt however this comes with its own issue. Running the ls command this way causes the shell to open two file handles for out.txt, both pointing to offset 0 in the file. So when ls looks for these two files, one of the messages gets clobbered.  What one would expect ls -l file missingfile &gt;out.txt 2&gt;out.txt to output:  -rw-r--r-- 1 blah blah 0 Jun  3 13:18 file ls: cannot access 'missingfile': No such file or directory   What is actually output:  -rw-r--r-- 1 blah blah 0 Jun  3 13:18 file le or directory   What is the best way to redirect both stdout and stderr to a file in a POSIX compliant fashion? Let $b_n$ be a sequence which decreases monotonically to zero, prove $\sum b_nz^n$ converges for $|z|\leq 1$ and $z\neq 1$.  So I was able to prove it converges on the open unit disk in the complex plane, but except for a few special points on the boundary, such as $-1$ and $i$, where I was able to use the alternating series test, I can't seem to prove it converges in general on the boundary minus $z=1$.  I feel I have to somehow use the fact that all the numbers on the unit circle except $z=1$ rotate around and around as you raise them to higher and higher powers, thus you get the real and imaginary parts of your series to alternate between sets of positive and negative terms, but in a very irregular way for most initial angles.  I tried to simplify the problem by breaking the series into its real and imaginary parts, and then trying to prove they each converge separately, but I still can't prove either converges:  $$\sum_{n=0}^{\infty}b_ne^{n\theta i} = \sum_{n=0}^{\infty}b_n\cos(n\theta) +i\sum_{n=0}^{\infty}b_n\sin(n\theta).$$ Topological Circuit Simulator Does something like  exist for topological (eg. braided) circuits?   Alternatively, any ideas on how @ is getting  (or something similar)? I'm curious whether I can find the overlap $\langle q | p \rangle$ knowing only the following:   $|q\rangle$ is an eigenvector of an operator $Q$ with eigenvalue $q$. $|p\rangle$ is an eigenvector of an operator $P$ with eigenvalue $p$. $Q$ and $P$ are Hermitian. $[Q,P] = i \hbar$.   I'm asking because books and references I've looked in tend to assume that $Q$ is a differential operator when viewed in the $P$-basis, then show that it satisfies the commutation relation. (I haven't read one yet that proves that the form given for $Q$ is the only possible one.) I've heard, though, that we can work purely from the hypothesis of the commutation relation and prove the properties of $Q$ and $P$ from it. The durability of iron tools is really starting to annoy me, but in all my hours of playing I've only stumbled across one deposit of diamond ore that provided around 7 Diamonds. What's the best way to locate more in Survival mode? Where is it most commonly found? Is the "live" in "He only lived a few days after the accident" intrasitive or transitive? I'm looking for an idiom or saying that I could use when people are focusing too much on small details and not seeing the big picture.  A couple that come to mind are "being penny-wise and pound foolish" and "rearranging deck chairs on the Titanic". However, the former doesn't fit what I'm thinking of because the present activity might not be wise. The latter implies too much about impending doom.  For example, let's say some company is spending all their time refining a small detail in their product, while ignoring a major opportunity shift in the industry. What phrase could I use there?

I am debating whether or not to get the Potato Sack (yes, I realize I've been debating for several weeks now) bundle through steam.  I already own: Defense Grid: The Awakening, Super Meat Boy, and Audiosurf, all of which are part of the sack pack. What happens if I buy the Potato Sack?  Do I get 2nd copies of the three above mentioned games to gift elsewhere?  Is the price of the bundle reduced by the games I already have?

Then  $$ \begin{align} (2x-1)\,dx &amp;= dt\\ dx &amp;= \frac{1}{(2x-1)}dt \end{align} $$  Changing the limits of integration, we get  $$\int_{1}^{1}\tan^{-1}(t)\cdot \frac{1}{(2x-1)}dt = \int_{1}^{1}\tan^{-1}(t)\cdot f(t)dt = 0 $$  where $f(t)=\frac{1}{(2x-1)}$.  Is it true that $\int_{a}^{a}f(x)dx = 0$? If not, then where have I made a mistake in my attempted solution?
