How do I remove Windows but keep Ubuntu? What's the easiest way to unrar a file? I just realized I can't unrar .rar files on my Ubuntu machine!  What's the easiest way to accomplish this fundamental task? If possible I'd love something like 7Zip that I can just right Click, and extract and have the program worry about how to do it regardless if it's a .zip, a .rar or a .foo compressed file. Increasing Flood Plain I am doing a project where we are attempting to determine how many more buildings would flood if the FEMA flood plain increased by 1',2' and 5'. I have the elev of the flood plain rasters from lidar data, but I am having trouble figuring out how much more area will be inundated by the rises I described earlier. I'm using raster calc and I have a buffer for the flood plain that also has elevation data. Any thoughts? Ubuntu 18.04 - Dell XPS13 9370 no longer suspends on lid close This was working perfectly on 17.10 but after upgrading to 18.04 yesterday, when the lid is closed the screen turns off but doesn't suspend properly.  I travel around a lot and immediately noticed the heat (and battery draining) when taking it out of the travel case.  I've tried uncommenting these lines in /etc/systemd/logind.conf  HandleLidSwitch=suspend HandleLidSwitchDocked=suspend   and restarted but didn't make any difference. What is the effect of the number of cross-type focus points on sharp focus? Take a screenshot of a webpage with JavaScript? How to guess a curve distribution from count data I have a sample composed by 2500 count data values. I've plotted in R the corresponding histogram and ecdf. I've run the One-Sample Kolmogorov-Smirnov test to check if the distribution is either exponential or poisson, but I got negative results.  Is it possible that the One-Sample Kolmogorov-Smirnov test, it's not the correct test to work with this count data.  What is the best way to identify a distribution for this kind of data? How can I take a photo using a slow shutter speed without it being overexposed? When I try to take a picture using a slow shutter speed in daylight it is overexposed. How can I change the settings so it isn't overexposed? I have been using the app for 3 days now. I just opened it up again, and it asked me to sign "up" again with either Google or the Trainer server.   So I signed up with the same Google account as when I first started with and the game started again.   Is there Any way I can get my progress back? Are there any Combinatoric proofs of Bertrand's postulate? I feel like there must exist a combinatoric proof of a theorem like: There is a prime between $n$ and $2n$, or $p$ and $p^2$ or anything similar to this stronger than there is a prime between $p$ and $(\prod_p p) + 1$ (Euclid's theorem).  I was trying to prove one by the Sieve on this grid      1     2     3     4 ... p   p+1   p+2   p+3   p+4 ... 2p  2p+1  2p+2  2p+3  2p+4 ... 3p ........................... ........................... ........................... p^2 p^2+1 p^2+2 p^2+3 p^2+4 ...   but it did not work.  Do any good arguments like this exist? I don't expect anything as strong as Prime Number Theorem or even Bertrand, but surely a direct combination proof can prove that there are lots of primes? If you have a single atom in a box, what state of matter would it be in? If the walls of the box were made of a completely inert material, what state of matter would the atom be in? Or would it not have one? I realized this is a duplicate of several other questions. How to find effects of magical items? Similar to this , but specific to D&amp;D 5e, how are players meant to find out the effects of items/potions/scrolls/weapons/armor?  Say, they find a potion in some chemist's chest. It is red and smells nice. Should they perform an investigation/perception check? Or an arcana/nature check? If I tell the players specifically to do an Arcana check, then I am already hinting at the fact that this potion will have some magical effect. It could just be a natural elixir concocted by Druids to help your health regen.  Same goes for weapons. They find the legendary bow of X, which has a +3 to hit and a 10% chance of striking other enemies near the target. I describe the bow as unique, glowing, made from dragon scales and hovering on air. Would they investigate their properties? Or just I just let them fire at a wall until something happens?   Our playstyle so far has been to use active checks for a quick understanding of the item (drink a little bit of Potion as an Investigation check to find whether it heals or not, sensing magical properties of the bow with Arcana checks). When time is available, and experimentation is necessary, allow the PCs to do some creative testing and, based on their ideas, "After Y time, you realize that the bow sometimes hits several points of the wall instead of just your target".  According to the RAW, is there a specific way of checking the stats/effects of such items? Splitting all lines in layer at vertices using QGIS If I'm not wrong, torque is perpendicular to both the radius and force i. e. It is along the axis of rotation. Questions that arise are- why do we consider the length between the axis/point of rotation while calculating torque? More importantly why is torque a cross product?

How to roll back Ubuntu to a previous version? I just installed a new version of Ubuntu and I want to roll it back to the previous version.  How can I do that? Is that even possible? I have upgraded 14.04 to 16.04 . Now I am trying to open the gedit from terminal by passing the command:    sudo gedit /some/where/file.txt   but it is throwing an error stating that:    (gedit:2090): Gtk-WARNING : Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:   The name org.gnome.SessionManager was not provided by any .service files**   However, it is opening the file. When I try to save any modification then it is showing this error after saving the file:    (gedit:2090): WARNING : Set document metadata failed: Setting attribute metadata::gedit-position not supported   I am not getting why this is happening in 16.04 only; it was not on 14.04. How to change an input button image using CSS So, I can create an input button with an image using &lt;INPUT type=&quot;image&quot; src=&quot;/images/Btn.PNG&quot; value=&quot;&quot;&gt;  But, I can't get the same behavior using CSS. For instance, I've tried &lt;INPUT type=&quot;image&quot; class=&quot;myButton&quot; value=&quot;&quot;&gt;  where &quot;myButton&quot; is defined in the CSS file as .myButton {     background:url(/images/Btn.PNG) no-repeat;     cursor:pointer;     width: 200px;     height: 100px;     border: none; }  If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good, because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using JavaScript, but I'm looking for a CSS solution. I'm using Firefox 3.0.3 if that makes a difference. In ideal gas model,  is the measure of average kinetic energy of the gas molecules. If by some means the gas particles are accelerated to a very high speed in one direction, KE certainly increased, can we say the gas becomes hotter? Do we need to distinguish the random vibration KE and KE in one direction?  Furthermore, if we accelerate a block of metal with ultrasonic vibrator so that the metal is vibrating in very high speed with cyclic motion, can we say the metal is hot when it is moving but suddenly become much cooler when the vibration stop?
