In windows we can capture scrolled window using the software SNAGIT   Is there a software or utility that can be used to capture the entire page.
As the title of the Question states, I want to know what are the tools available for Ubuntu which would allow me to take screenshots of "Scrolling Windows" ie; tall webpages, tall nautilus window which contains lots of files and folders etc. as a single image file.  For the sake of clarity, I have already seen . However, I am specifically looking for tools to capture Scrolling Windows.  As an example, my personal favorite for Microsoft Windows is . It's light on resources and helps me take beautiful screenshots. Is there anything close to it available for Ubuntu?
Is $\mathbb{Z}[x]/(x^2+1)$ isomorphic to $\mathbb{Z}[i]$? I think it would make sense to split up the flag "This is not an answer" into three flag choices:   This should be a comment This should be an edit This should be a new question   If we had that, it would make it easier (and therefore more efficient) for mods to figure out what to do with answers flagged thusly. 2D inhomogeneous biharmonic equation There are many times when I curse the autocorrection mechanism for changing what I typed, but overall, much of the corrections are welcome so I don't really want to disable it. I do want to have it do it's work but alert me when it makes each change so I don't have to proofread everything or focus with perfect attention to the screen to see the momentary red and/or blue underlining that alerts me to the machine override.  I would love a way to turn on an audible beep (customizable of course) so that I also get a warning each time my typing gets corrected (and only when autocorrection occurs). How to make nautilus forget saved password? I am browsing Shared folders on a Windows network through Samba.  When I first opened a system on the network I was asked for a login username, password and I checked the save-password setting. Now the shared folder opens directly without asking for authentication.  I want to browse the folder using a different user which has more access rights. How should I do that? Is it safe to use oil at its smoking point? Teflon toxicity and second degree burns aside, are there any health issues related to cooking with oil at or past its smoking point? Googling a bit I found one article that went so far as to say you should always "discard oil that's reached its smoke point, along with any food with which it had contact". Other searches showed pages suggesting cancer risks.  I've never given it a thought before and I often use peanut oil at smoking point to brown meat. The "Info" bar on top disappeared and the mouse pointer is misaligned I have a problem with Blenders UI. The "Info" bar on top disappeared and the mouse pointer is misaligned. I reinstalled Blender 2 times, deleted every leftover files  but it still does the same thing. This is in v2.78c. The weird thing is that on the bottom everything works fine. Here are some images: I want to make someone a present by subscribing for him to a mathematical journal. (It should appear every month or every two months). The contents should be comprehensible to an undergraduate in mathematics, and be about a broad selection of topics (for example not only analysis).   I expect the content to be something like proposing interesting problems and then giving solutions with some references for further study. Are there some famous journals you could suggest me? I am very new to the TikZ package, and I need to draw some flow chars by using the following shapes.   However I couldn't figure out how to draw the 4th and and 6th ones below. It would be very nice (for completeness) to help with all of the shapes in the list below.      Your help will be greatly appreciated.  Note: I have visited  but it contains some other shapes. Lots of questions in the reopen queue Is it possible to mount on a PC an SD card that has been encrypted by an Android Marshmallow device? I have a Samsung Galaxy S5 duos with stock Android Marshmallow, and I'm considering encrypting my SD card to prevent access to its contents in case I lose my phone. The main reason of not doing this is that I'm not sure if there's a way to mount an encrypted SD card on Windows (or other desktop OS's)   When I encrypt the SD card on my Samsung Galaxy S5, is it using a known implementation of encryption, or is it something that only works on Android (or perhaps Samsung) phones?   I do not want to use USB connection to my phone to access my SD card, it's terrible. Mounting the SD card is much easier and faster and less annoying.   EDIT: just to clarify, I am NOT talking about adoptable storage. I want a portable encrypted SD card that can both be read on PCs and Android phones (i.e. I want to be able to remove the SD card from my phone, plug it into my PC, provide a password to decrypt and read/write it like any other SD card) Polynomial in $n$ variables Let $f$ be polynomial in $n$ variables. If we have $f(a_1,\ldots,a_n) = 0, a_i \in S_i$ and $S_1,\ldots,S_n$ are infinite subsets of a field $k$, how can I show that $f=0$? Does voltage drop occur with zero load and zero resistance My WordPress website currently uses this custom permalink structure: %author%/%year%/%monthnum%/%day%/%postname%  In this case, %monthnum% instantiates numbered dates with a leading zero -- e.g., "09" for September. So, a sample URL might look like this: mywebsite.com/username/2012/09/12/post-name  Is there a function I can add or .htaccess change that I can make which will remove the leading zeros from my permalink stucture? So, using the example above, my URLs would ideally look like this: mywebsite.com/username/2012/9/12/post-name  Thank you! I've read up on WordPress' structure tags documentation (http://codex.wordpress.org/Using_Permalinks), but I can't find any solutions or plugins for the above-mentioned problem.

When making a custom launcher, it is nice to have a matching icon for it from the default usr ubuntu directories. The problem that is: Ubuntu seems to store icons in about 50 or more folders. Browsing all of them in nautilus takes ages.  So my question is: Is there some kind of icon browser that shows an overview of all icons in /usr/share/icons/*? How do I get an XBOX 360 controller working? I have a Microsoft XBOX 360 gamepad with the wireless adapter and I was wondering what I would have to install to use them with Ubuntu I do know that when using this on Windows I have to manually install the drivers for the wireless receiver (if that is relevant.) If user input is inserted without modification into an SQL query, then the application becomes vulnerable to , like in the following example:  $unsafe_variable = $_POST['user_input'];   mysql_query("INSERT INTO `table` (`column`) VALUES ('$unsafe_variable')");   That's because the user can input something like value'); DROP TABLE table;--, and the query becomes:  INSERT INTO `table` (`column`) VALUES('value'); DROP TABLE table;--')   What can be done to prevent this from happening? Alignment of axis in tikz How can top principal components retain the predictive power on a dependent variable (or even lead to better predictions)?
