Sketch complex curve $z(t) = e^{-1t+it}$, $0 \le t \le b$ for some $b>0$ Find running median from a stream of integers How would I prove that for all elements of a set {n | n ∈ ℕ ∧ n &gt; 7} (all natural numbers greater than 7), there are multiples of 3 and 5 which, when added up, are equal to that element of the set?  A := {n | n ∈ ℕ ∧ n &gt; 7} ∀ n ∈ A: n = x*3 + y*5   I do understand why this is true:   8 = 1*3 + 1*5 9 = 3*3 + 0*5 ...  15 = 0*3 + 3*5   and this pattern repeats once 16 is reached, as 8 can be replaced with 1*3 + 1*5, so I'd basically have to add 1 to x and y for every time 8 fits in n.  I am however not sure how I can formulate this mathematically correct.  Thanks in advance, CrushedPixel Does everyone see the same Pokémon? I was wondering if everyone sees the same Pokémon on the map. If I catch all the Pokémon around me will others be unable to get any? Is it ever acceptable to have a  in your C or C++ application?  What if you allocate some memory and use it until the very last line of code in your application (for example, a global object's destructor)? As long as the memory consumption doesn't grow over time, is it OK to trust the OS to free your memory for you when your application terminates (on Windows, Mac, and Linux)? Would you even consider this a real memory leak if the memory was being used continuously until it was freed by the OS.  What if a third party library forced this situation on you? Would refuse to use that third party library no matter how great it otherwise might be?  I only see one practical disadvantage, and that is that these benign leaks will show up with memory leak detection tools as false positives. How can wifi penetrate through walls when visible light can't? I did search the question on Physics S.E considering it would be previously asked. I found this  But in this question , the answers are w.r.t to or in comparison with microwaves , their absorption and certain other things. I didn't find a sort of general answer that could be the answer to the question. So the question is - wifi or radio waves  reach us through concrete walls . They also reach us through the ceiling (if some one is using it in the flat above ours ). Even through the air they travel such a lot , bending around corners or doors . Now I would not compare them to microwaves (because I don't want the answer in terms of properties of the material but physics). Visible light which is so much powerful than them can't penetrate black opaque paper leave alone the walls. Same is true for gamma rays (penetration through a very thick wall). So why then radio waves being so very less powerful than light  waves are able to travel through walls? There should be a general concept as to why the radio waves are able to pass through walls but microwaves or light waves cannot ! A linked question is also that sound travels much faster in solids(walls) but is not audible in it though it is in air. After reading @BillN's answer, it would be really helpful if any one could explain it in terms molecular resonance or crystalline structure or electrical conductivity or how does molecular resonance or crystalline structure or electrical conductivity cause this. How can I evaluate $\sum_{n=0}^\infty(n+1)x^n$? A circle has the same center as an ellipse and passes through the foci $F_1$ and $F_2$ of the ellipse, two curves intersect in $4$ points. how to loop through arguments in a bash script I flashed new firmware and before doing so backed up apps and data with Titanium Backup. How do I restore? I have the folder on my PC which contains two .gz files and a properties file. Linux - Running The Same Command on Many Machines at Once I have about a dozen Linux boxes that I occasionally need to run the same command(s) on. Is there an easier way (or automated way) to do this asides from logging on to each machine and running the command, one at a time? It's not the same commands all the time and it's not at a preset time so it's not something ideal for tools like cron. window.onbeforeunload and window.onunload is not working in Firefox, Safari, Opera? I have installed an Ubuntu server on a VMWare workstation with a space of 20GB storage as seen below;    After the installation I've attached another 40GB worth storage to the existing Ubuntu server installation (seen below);    Now I want to add this 40GB to my / (root) directory or to /var/ directory but my df -h result shows;  root@Userver:~# df -h Filesystem      Size  Used Avail Use% Mounted on /dev/sda1        18G  900M   16G   6% / udev            990M  4.0K  990M   1% /dev tmpfs           400M  308K  399M   1% /run none            5.0M     0  5.0M   0% /run/lock none            999M     0  999M   0% /run/shm none            100M     0  100M   0% /run/user root@Userver:~#   What should I do now?

I like using Stack Overflow (or any other Stack Exchange sites) and was wondering if there was an app I could install on my phone or other device that would allow me to use the site on-the-go or straight from my desktop.  Some systems to consider:   Windows 8 Android iPhone/iOS   What are some apps that I could install to my computer or phone to enhance my Stack Exchange experience? Handling circular entity references with Migrate I am using  on a Drupal 6 to Drupal 7 migration right now.  I have three types: type1, type2, type3.  Each of the three types has a entityreference field on it, which is configured to be able to point to all three types.  This means that there can be circular references, and when a particular node is being migrated, the destination node may not exist yet and could potentially be any of the three types.  My migration class looks like this:  class MyNodeMigration extends DrupalNode6Migration {   public function __construct(array $arguments) {     parent::__construct($arguments);      $this-&gt;addFieldMapping('field_legacy_nid', 'nid');      $this-&gt;addFieldMapping('field_the_reference', 'field_the_reference')       -&gt;sourceMigration(array('type1', 'type2', 'type3');   } }  $node_arguments = array(   array(     'class_name' =&gt; 'MyNodeMigration',     'description' =&gt; 'type1',     'machine_name' =&gt; 'type1',     'source_type' =&gt; 'type1',     'destination_type' =&gt; 'type1',     'dependencies' =&gt; array('roles', 'users'),   ),    array(     'class_name' =&gt; 'MyNodeMigration',     'description' =&gt; 'type2',     'machine_name' =&gt; 'type2',     'source_type' =&gt; 'type2',     'destination_type' =&gt; 'type2',     'dependencies' =&gt; array('roles', 'users'),   ),    array(     'class_name' =&gt; 'MyNodeMigration',     'description' =&gt; 'type3',     'machine_name' =&gt; 'type3',     'source_type' =&gt; 'type3',     'destination_type' =&gt; 'type3',     'dependencies' =&gt; array('roles', 'users'),   ), );  $common_node_arguments = $common_arguments + array(   'user_migration' =&gt; 'users', );  foreach ($node_arguments as $arguments) {   $arguments = array_merge_recursive($arguments, $common_node_arguments);    Migration::registerMigration($arguments['class_name'], $arguments['machine_name'], $arguments); }   When I run the migrations, most nodes are fine, but I get a decent amount of Stubs (*) created.  Some of the destination nodes have the entityreference pointing to these Stub nodes.  The source nodes are fine.  What I have uncovered is that the bundle on the destination nodes that are being made as stubs are incorrect, and look like they are all type1.  A node of the proper type does end up being created, but it never gets set as the entityreference target.  Another way to explain this is that I end up with   node: nid=123, type=type1 node: nid=234, type=type1, field_the_reference=123 node: nid=345, type=type2   where it should be   node: nid=234, type=type1, field_the_reference=345 node: nid=345, type=type2   How do I handle this situation?  (*): a "Stub" in the context of this question here refers to a node which is created for the purpose of being a reference target, but does not get its data initially. The term is used throughout the Migrate documentation and source code. Most people say I wish I could, I wish you would.    Can we use I wish I can, I wish you will?    I'd like to know what the main differences between the usage of can/will and could/would are when wishing.  Is it related to the subjunctive? Because one says “I wish I were”, not “I wish I am”, so are would and could the subjunctive forms of can and will?  Or is it something else entirely? Reviewing a suggested edit from a review queue jumps to the suggested edit queue I was in the first posts review queue and chanced on a post with a suggested edit. (Note: I have enough reputation to review suggested edits.) I clicked on “edit (1)” and was taken into the suggested edits queue. When I approved the suggested edit, I was taken to the next suggested edit, and so on until there were no more suggestions (“There are no items for you to review.”, still in the suggested edits queue). In this situation, I think it would make more sense if I was brought back to that post I was working on in the first posts queue, as soon as I acted on its suggested edit. Alternatively, the suggested edit should be shown in the same kind of pop-up as on a question thread page. The same goes for other queues (late answers, low quality, etc.). Movie about gene therapy and genetics-based jobs I saw a movie several years ago and I have not been able to find it since.  It was about a dystopian society where parents could modify the genes of their children before birth.  Some individuals, including the protagonist, had not had this done, and so had a somewhat inferior genetic makeup.  Jobs are based on the results of genetic tests, and the protagonist, a male, was slated for a less than ideal job. In the movie, he fakes his identity and has major surgery to make him a little taller to match his ID. He is trying to get his dream job (astronaut?).  The only other parts I remember are   the protagonist, to keep up the ruse, managing to run on a treadmill faster than his  genetic limit a very suspicious character pulling the protagonist's DNA from a hair left in a comb What is the "correct" way of embedding text into math mode?
