Power failed during 16.04 LTS to 17.10 upgrade after successful download of files Download of files successful. Power failed about halfway through build.  Have used the tools in grub, e.g fsck to no avail.  Is there a root command that will restart the build from the new files? I'm unable to get to login, network, etc.  I can get in as root from grub restore menu. Norm13
How to repair Ubuntu installation after interrupted dist-upgrade without losing any custom settings? During my attempt to upgrade my Xubuntu 14.04 installation with  sudo apt-get dist-upgrade   I made the mistake of interrupting the process by closing my laptop, which caused it to suspend to disk. After re-opening, the monitor remained black, so I was forced to reboot the system. I have since discovered many failures of drivers (wlan0 missing, USB memory stick cannot be mounted, USB mouse not recognised, and maybe more undiscovered problems with hardware).   My beginner's attempts to manually repair the single problems could have made it even worse. During the installation of the current distribution I chose to encrypt my whole hard disk.
How do I add a Pokestop to my area? Recovering user files with a Live CD For some reason I can't boot my system. I get an error akin to Operating System Not Found.   I tried bootrepair, and that didn't work. So then I decided I would just save my personal files, wipe everything, and reinstall.   But in the live session, when I go to the /home directory, my username folder isn't there, instead it goes to the Live CD's desktop and other directories. Is there some other error occurring? Is there a way to recover the files? StructureMap error when invalid controller I am using Structure map like the MVC storefront by Rob Conery does and I have an AdminController and so to get to it I just type:  website/Admin/action   however if I miss spell the controller name I get the error below:  Exception Details: System.ArgumentNullException: Value cannot be null. Parameter name: key  There error occurs on this line:  Controller controller = ObjectFactory.GetInstance(controllerType) as Controller;   Does anyone have any ideas on how I can handle this error or not allow it to happen at all and maybe just goto a 404 page??  Cheers in advance What's difference between shadowing and overriding a method in C#? Ignore compile errors How can I set up a permanent compile loop that keeps trying even when there are errors? I'm using latexmk with a remote compile setup as discussed  and . However, if I save a document with a bug (either a legitimate bug, or I save it before closing a tag), then latexmk halts. Any suggests how I can have it pause, try again, and keep trying again, for ever and ever? Number of labeled trees which have one vertex of degree 4 How many labeled trees which have one vertex of degree 4 can we have? A tree with $10$ vertices has $9$ edges, so the sum of the degrees of the vertices is $2\cdot 9=18$. If there is one vertex of degree $4$, the sum of the degrees of the other $9$ vertices must be $14$. I don't know what to do next. Should I count all possible vertex degrees? What happens if 2 separate abilities require you to sacrifice a creature? If i have two cards that force opponents to sacrifice every upkeep like for example  "At the beginning of each opponent’s upkeep, Mogis deals 2 damage to that player unless he or she sacrifices a creature."  And  "At the beginning of your upkeep, draw a card unless target opponent sacrifices a creature or pays 3 life."  Does the oppenent have to sacrifice twice? Or if they sacrifice Mogis's ability have they not allowed me to draw from indulgent tormentor? When a PHP application makes a database connection it of course generally needs to pass a login and password. If I'm using a single, minimum-permission login for my application, then the PHP needs to know that login and password somewhere. What is the best way to secure that password? It seems like just writing it in the PHP code isn't a good idea. Where can I find computer modern fonts for use in other programs, e.g. Adobe Illustrator? LaTeX Error: Option clash for package xcolor Airplane ground speed and direction, given airspeed and wind An airplane heads northeast at an airspeed of 900 km/hr, but there is a wind blowing from the west at 60 km/hr. In what direction does the plane end up flying? (angle). What is its speed relative to the ground?   I drew a picture. I think I am having a hard time understanding how to solve the problem. I want to add the wind vector to the plane vector - is that as simple as 840 km/hr? After really adding the vectors together, do I do: (added vectors)cos(45)? How do you Xforward windows using ssh? What is the difference between cascade & inverse in hibernate, what are they used for? How do I set environment variables from Java? How do I set environment variables from Java?  I see that I can do this for subprocesses using . I have several subprocesses to start, though, so I'd rather modify the current process's environment and let the subprocesses inherit it.  There's a System.getenv(String) for getting a single environment variable. I can also get a Map of the complete set of environment variables with System.getenv(). But, calling put() on that Map throws an UnsupportedOperationException -- apparently they mean for the environment to be read only. And, there's no System.setenv().  So, is there any way to set environment variables in the currently running process?  If so, how?  If not, what's the rationale?  (Is it because this is Java and therefore I shouldn't be doing evil nonportable obsolete things like touching my environment?)  And if not, any good suggestions for managing the environment variable changes that I'm going to need to be feeding to several subprocesses?

I am having trouble with this problem from my latest homework.  Prove the arithmetic-geometric mean inequality. That is, for two positive real numbers $x,y$, we have $$ \sqrt{xy}≤ \frac{x+y}{2} .$$ Furthermore, equality occurs if and only if $x = y$.  Any and all help would be appreciated.
