The question may be trivial but with this simple for loop  for i in {1..10000000}; do echo "$i" line &gt;&gt; file done   my shell crashed after some elaboration time (the tab in the terminal emulator was automatically closed) and file was not created.  It is GNU bash, version 4.1.11(2)-release.  Is this due to a memory limit or what else? And if yes which should be this limit?  With {1..1000000} it worked correctly.
IINM my system is failing when bashing  for i in {0..10000000}; #   Seven zeroes. do     false; done #   `bash` exited and its `tmux` pane/window was closed.   or  for i in $(seq 0 10000000); #   Seven zeroes. do     false; done #   `bash` exited and its `tmux` pane/window was closed.   but not when  for i in {0..1000000}; #   Six zeroes. do     false; done #   Finished correctly.   Can you please briefly explain the internals of this behavior and prompt a workaround for getting the task done?
Why is this trigger finding a null value despite the field being populated? Intertext vertical spacing How do I reduce the vertical spacing of \intertext? using gedit through ssh connection - should I have gedit installed on the server? I wanted to try out using graphical tools over ssh. Just to learn a new thing :)  so my understanding is this, I connect like this: ssh -port -x user@server  But I'm running ubuntu server so it has no gui and thus no gui tools. My understanding is I've to install gedit on server. But also xserver?  Can someone clear up this concepts to me? Can't execute terminal commands: "the command 'sudo' is available in '/usr/bin/sudo'" Get selected element's outer HTML I still do not understand what a  precisely is. Is it exactly the same as a particle? Or only an excited state?  And why does it make a peak in some diagrams? And which diagrams? Why isn't my Minecraft LAN server working? My LAN server won't let my cousin join me or me join my cousin. It won't show up on the multiplayer screen - it keeps saying "scanning for LAN servers" but it never finds it. I am at his house and we use different computers but it won't connect. How can I fix this? Inverse metric in linearised gravity From what I've read, in the framework of linearised gravity, one perturbs the metric around a Minkowski background, $\eta_{\mu\nu}$, such that  $$g_{\mu\nu}(x)=\eta_{\mu\nu}+h_{\mu\nu}(x)\tag{1}$$  where $h_{\mu\nu}(x)$ is a small perturbation, i.e. $$\big\lvert h_{\mu\nu}\big\rvert&lt;&lt;1.\tag{2}$$  The inverse metric is then found by assuming the following ansatz:  $$g^{\mu\nu}(x)=\eta^{\mu\nu}+\tilde{h}^{\mu\nu}\tag{3}$$  where $\tilde{h}^{\mu\nu}$ is also small (i.e. $\big\lvert \tilde{h}_{\mu\nu}\big\rvert&lt;&lt;1$).   Using this, it is easy to find that  $$g^{\mu\nu}(x)=\eta^{\mu\nu}-h^{\mu\nu} \tag{4}$$  to first order.   My question is, what is the justification for this ansatz? Is it simply that one expects the inverse metric to have a similar form to the metric in order to satisfy $$g^{\mu\alpha}g_{\alpha\nu}=\delta^{\mu}_{\;\nu}~?\tag{5}$$ I'm not entirely clear on how Counterspell works, when trying to counter higher-level spells: the CS description only talks about disrupting a creature you can see, within 60 feet, casting a spell.   However, when trying to counter a higher level spell:   Do I know what spell is being cast?  Do I at least know (somehow intuit, based on VSM components) the level of the spell? Or can I tell the spell/level of the spell by sensing a disturbance in The Weave? (I.e., if the spell is being cast using Subtle Spell, can I still tell what's going on?)   The point of the question is to determine how fruitful CS can be in combat--if I know what the other guy/gal is casting (or at least the level), I can decide whether I want to spend my L8 slot to counter his/her L8 slot. But if I have no idea, and I end up using a L8 slot to counter a L3 spell... seems a bit painful.  Hope this made sense! Custom blocks created as a plugin in a module not showing for Block::load() I have a couple of blocks that have been created using the ... extends BlockBase syntax in my module. They work perfectly fine, and I can add them on the blocks layout page, can add them into DS as a field, etc. They definitely exist fine.  However, when I try and render them using Block::load(), they won't show up, unlike other blocks that work fine.  For example, if I have the following docblock:  /**  * Provides a 'Cute Cats' Block.  *  * @Block(  *   id = "cute_cats",  *   admin_label = @Translation("Cute cats yo"),  * )  */  class CuteCats extends BlockBase { ... }   ... and then try and call it like this:  $block = \Drupal\block\Entity\Block::load('cute_cats'); return render(\Drupal::entityTypeManager()   -&gt;getViewBuilder('block')   -&gt;view($block));   Any idea why? Thanks in advance. I have recently noticed a rather large amount of small worms in the fresh cod I am buying. I have tried to take them out as much as I can and of course have spoken to my fish supplier about them, but he assures me they are harmless. However, I don't believe my customers would be as assured. Is it okay to serve this fish, taking into account I might miss a worm or two? How do I programmatically obtain the version in JBoss AS 5.1? Looking for the name of a post apocalyptic/sci-fi tv show or film Every once in a while this starts nagging me, I have really no idea and not much to go on so here goes...  A man wearing a blue? uniform walks into a town that looks abandoned and empty and all covered in dust.  The skies are brown/dirty with no sun.  He goes into the upstairs of one of the houses. He stops at I think a fireplace, examines something, or it’s like he’s remembering something.  Then downstairs in the street, a man/person wearing rags/robes with bandages covering his face starts banging on a fire hydrant with a stick/pipe. More people in bandages/robes start appearing, there's a chase in the town. I don't remember much but he's chased into wastes? through a gully or ditch and then a vehicle (only really remember that it was steel in colour) shows up and a woman comes and shoots one or two of the people chasing him.   That’s about all I remember. I was about 6 or 7 maybe and it was afternoon maybe a little later.  I thought maybe Star Trek, but after searching I don't think it is. I think it might be 80's, maybe early 90's. I think it's sci-fi rather than post-apocalyptic. How do you perform a left outer join using linq extension methods Assuming I have a left outer join as such:  from f in Foo join b in Bar on f.Foo_Id equals b.Foo_Id into g from result in g.DefaultIfEmpty() select new { Foo = f, Bar = result }   How would I express the same task using extension methods? E.g.  Foo.GroupJoin(Bar, f =&gt; f.Foo_Id, b =&gt; b.Foo_Id, (f,b) =&gt; ???)     .Select(???) Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times? For example, can a regular expression match an opening and closing brace when there are an unknown number of open/close braces nested within the outer braces?  For example:  public MyMethod() {   if (test)   {     // More { }   }    // More { } } // End   Should match:  {   if (test)   {     // More { }   }    // More { } } \centering doesn't seem to center my text I am trying to center this page but it will not work.  All is get is for the first line to be indented about one "tab" space to the right, but the second line will not shift.  However, the first line's indent does not appear to be centered either.  Is it possible that the binding offset or the indentfirst package is interacting with this negatively?  All of the other pages seem to work just fine. Any help would be appreciated.  \documentclass[12pt, a4paper, twoside]{article} \usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry} \usepackage[T1]{fontenc} \usepackage{indentfirst} \begin{document} \pagestyle{empty} \vspace*{36 pt} {\centering \textbf{\emph{\Huge{Since I Saw You Last,\\There's a Change Upon You}}} } \end{document} What happens if I unsubscribe from Apple Music, then resubscribe at a later date? I want to cancel my apple music subscription for now, but may want to bring it back this summer. Will all the music I added be permanently removed when I unsubscribe, or will re-subscribing retrieve all my previous music? Where is the usage of Ubuntu cloud guest image on OpenStack documented?

Rights if we possess Carta di Soggiorno? I have searched the internet but could not find specific information so if we have got the following document "Carta di Soggiorno di Familiare di Un Cittadino Dell'Unione" (Residence Card of a family member of a Union Citizen, Italy) issued by the Italian authority, what rights do we possess of working inside Italy and EU? What about travelling? Will we be requiring visas for the states which are are not in Schengen?
