I don't use things like Ubuntu One. How do I disable it from Startup Applications? I believe it is hidden by default along with some other apps.
How do I manage (add/remove) all the startup applications in Ubuntu 11.10 and up?  Startup Applications doesn't show all the applications which are started during boot.
Everytime I sudo apt-get update it always not complete and will say in the end  E: Read error - read (5: Input/output error) E: The package lists or status file could not be parsed or opened.   Same goes, when I try to install something and do sudo apt-get install &lt;some app&gt;  What should I do ? I admit, that my drive has bad sectors, could that be the reason? Is there anything else I can do? How to know if a time series is stationary or non-stationary? A physical explanation for negative kelvin temperatures Set title for each terminal tab in gnome-terminal using a bash script I'm using Ubuntu 16.04  I want to open multiple terminal tabs, run commands and set title. I can open multiple tabs with this command:  gnome-terminal --tab -e "command1" --tab -e "command2"   but cannot use --title option as it is not available in this version.   I know mate-terminal can do this, but I want to use gnome-terminal.   I've applied solution posted  and it worked but when i run  gnome-terminal --tab -e "bash -c 'set-title 99;ping 192.168.7.99'"   It shows:  bash: set-title: command not found PING 192.168.7.99 (192.168.7.99) 56(84) bytes of data. 64 bytes from 192.168.7.99: icmp_seq=1 ttl=128 time=0.425 ms 64 bytes from 192.168.7.99: icmp_seq=2 ttl=128 time=0.353 ms 64 bytes from 192.168.7.99: icmp_seq=3 ttl=128 time=0.335 ms   I also applied   I've also read this post  but the accepted answer did not solve my issue in 16.04 os or gnome-terminal version 3.18.3 and other solution provides to use other terminal xterm and I want to use gnome-terminal. I'm using a class I've derived from DocumentPaginator (see below) to print simple (text only) reports from a WPF application. I've got it so that everything prints correctly, But how do I get it to do a print preview before printing? I have a feeling I need to use a DocumentViewer but I can't figure out how.  Here's my Paginator Class:  public class RowPaginator : DocumentPaginator {     private int rows;     private Size pageSize;     private int rowsPerPage;      public RowPaginator(int rows)     {         this.rows = rows;     }      public override DocumentPage GetPage(int pageNumber)     {         int currentRow = rowsPerPage * pageNumber;         int rowsToPrint = Math.Min(rowsPerPage, rows - (rowsPerPage * pageNumber - 1));         var page = new PageElementRenderer(pageNumber + 1, PageCount, currentRow, rowsToPrint)                        {                            Width = PageSize.Width,                            Height = PageSize.Height                        };         page.Measure(PageSize);         page.Arrange(new Rect(new Point(0, 0), PageSize));         return new DocumentPage(page);     }      public override bool IsPageCountValid { get { return true; } }      public override int PageCount { get { return (int)Math.Ceiling(this.rows / (double)this.rowsPerPage); } }      public override Size PageSize     {         get { return this.pageSize; }         set         {             this.pageSize = value;             this.rowsPerPage = PageElementRenderer.RowsPerPage(this.pageSize.Height);             if (rowsPerPage &lt;= 0)                 throw new InvalidOperationException("Page can't fit any rows!");         }     }      public override IDocumentPaginatorSource Source { get { return null; } } }   The PageElementRenderer is just a simple UserControl that displays the data (at the moment just a list of rows).  Here's how I use my Row Paginator  PrintDialog dialog = new PrintDialog(); if (dialog.ShowDialog() == true) {     var paginator = new RowPaginator(rowsToPrint) { PageSize = new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight) };      dialog.PrintDocument(paginator, "Rows Document"); }   Sorry for the code dump, but I didn't want to miss something relevant. Where did the "wheel" group get its name? The wheel group on *nix computers typically refers to the group with some sort of root-like access. I've heard that on some *nixes it's the group of users with the right to run su, but on Linux that seems to be anyone (although you need the root password, naturally). On Linux distributions I've used it seems to be the group that by default has the right to use sudo; there's an entry in sudoers for them:  %wheel ALL=(ALL) ALL     But that's all tangential; my actual question is: Why is this group called wheel? I've heard miscellaneous explanations for it before, but don't know if any of them are correct. Does anyone know the actual history of the term? Solidify thickness doesn't correspond to specified scale I'm Having trouble with setting the thickness applied by solidify. The selected block is 15 by 28 cm (single mesh sides) and the thickness of solidify is set to 3mm (pointing inwards). Checking off even thickness makes it even worse. I was using the function in a different object earlier today and it worked just fine. Is there something I'm missing or is this just a bug?   Feel free to treat me like an idiot, I've literally started using blender yesterday :) Terminal appears with much delay when shortcut is used When I press Ctrl+Alt+T the Terminal opens after around 30 seconds. That's pretty annoying. If I open it with Alt+F2 and enter gnome-terminal the window appears instantly as usual.  I'm using Ubuntu 16.04 with gnome3.  Thank you for your help in advance! Determine if Type is a pointer in a template function How to prove that a continuous function, homotopic to the constant map $f:S^1\to S^1$  (a) has a fixed point and that (b) has a point $x$, such that $f$ maps $x$ to its antipodal point $-x$? Can I travel to Croatia with single-entry Schengen visa? I am traveling to Zurich with a single-entry Schengen visa.  While coming back can I travel to Croatia for 3 days and then return to India (Country of Origin)? How do I run an application with arguments from the command line without losing the terminal? I use dwm as a window manager on Ubuntu, I like tiled windows and I like them as few as possible. I sometimes need to run an application (let's say it's the pdf viewer mupdf in x11) from the terminal, the application will be launched in a new window but the terminal from which I launched becomes this prompt-less console for that application to log whatever.  I use dmenu to launch applications, but sometimes an application needs arguments (file names) to start. I use uxrvt within x11 managed by dwm. I have an exercise found on a list but I didn't know how to proceed. Please, any tips?  Let $X$ be a connected subset of a connected metric space $M$. Show that for each connected component $C$ of $M\setminus X$ that $M\setminus C$ is connected.

Moderator flag notifications should reach mobile I spend a great deal of time surfing SE sites from my phone during commutes and other down times. The global inbox is quite effective at reaching me even for chat pings. Quite frankly the mobile site is very well done!  However as a community moderator, there is a whole class of information not getting through. There are no notifications for moderator flags! I can switch to the full site and see these but that is inconvenient for browsing, so I only end up checking for flags periodically.  Ideally the moderator tools should all be available in mobile templates, but as a stand-by it's reasonable to switch to the full view to handle flags, but flags would get addressed in a much more timely manner if I knew about them. As it stands I often come and go from the site without even knowing there are outstanding flags.  A simple flag counter added to the header next to the notification counter and linked to the tools page (which automatically opens the full version anyway right now) would fix this. I know that the rotation period of the moon equals its revolution period. It's just so astonishing that these 2 values have such a small difference. I mean, what is the probability of these 2 values to be practically the same? I don't believe this to be a coincidence. It's just too much for a coincidence. What could have caused this? Both the Romulans and the Federation have regularly violated the Treaty when it suits them. Starfleet has obviously developed and manufactured cloaking/stealth technology and the Romulans make regular excursions across the Neutral Zone. They obviously aren't declaring all-out war, so what penalties or sanctions have been imposed for violations?  -edit added for clarity-  Has either side ever 'punished' their own people for any violations of the Treaty? In eevee, shadows are clipped by camera distance Why split the  tag when writing it with document.write()? Why do some sites (or advertisers that give clients javascript code) employ a technique of splitting the &lt;script&gt; and/or &lt;/script&gt; tags up within document.write() calls?  I noticed that Amazon does this as well, for example:  &lt;script type='text/javascript'&gt;   if (typeof window['jQuery'] == 'undefined') document.write('&lt;scr'+'ipt type="text/javascript" src="http://z-ecx.images-amazon.com/images/G/01/javascripts/lib/jquery/jquery-1.2.6.pack._V265113567_.js"&gt;&lt;/sc'+'ript&gt;'); &lt;/script&gt; Keyboard shortcut to autocomplete the user in comments
