How can I use the Alt + right click shortcut in Ubuntu 17.xx and higher without installing additional software?
I am trying to use the Alt+Right Click to select edge loops in Linux Mint but this shortcut doesn't work it is already used for Linux to reduce a window. I have checked the keyboard shortcut but it doesn't appear.
Where should the apostrophe go on a possessive abbreviation? When expanding an abbreviation in parentheses, sometimes the thing that was abbreviate was used in a possessive context.  Consider the following example:     If the Giant Ostrich Bomb's (GOB) fuse is too short, you may be too close when it goes off and you may get kicked in the face.   Is the above correct, or should it be rewritten this way instead:     If the Giant Ostrich Bomb (GOB)'s fuse is too short, you may be too close when it goes off and you may get kicked in the face.   If this is a matter of style, do any of the popular style manuals have a recommendation? It is not unusual for an Ubuntu (or other distro with apt package management) user to encounter the error: user@box ~ $ sudo apt install x [sudo] password for user:  Reading package lists... Done Building dependency tree        Reading state information... Done Package x is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source  E: Package 'x' has no installation candidate  There have been several questions asked concerning this on various StackExchange sites,for example  on AskUbuntu, but these are generally about how to obtain the specific package despite the error. I have found no package that is not found simply (though not always easily) by determining if it is still distributed, and under which repository if so, and ensuring that repository is in apt.sources, or the worst comes to the worst downloading a .deb or source to compile. So my question is more general, and although I am guessing it has a rather simple and therefore non-exciting answer I cannot think how to find it by conventional search engine methods, so I turn to AskUbuntu: Is there a command or option I can use to determine what package / which packages reference the missing package? How can friction do no work in case of pure rolling? I have read various answers , on PSE and elsewhere , and most of them explain that the point of contact of the rolling object undergoes 0 instantaneous displacement in the direction of friction, I agree , but then there is a feeling that the friction does provide a torque , so how can it do 0 work . ( The pure rolling here is under a constant external force on the object so friction does act ). I used a website called Seeking Arrangements and met a  sugar daddy. He asked for my email login, online banking login, routing, account number, Facebook, as well as my  address which is the only thing I gave him since it’s a PO. I’ve been extremely vague just to see if this is real.   I don’t plan to give him anything because I have only been talking to him for a few months and  I feel conflicted. I doubt that he is trying to scam me but I suspect that he has some kind of master plan. With things such as Venmo, Zelle, and Cashapp, what is the need for “put me on his payroll?”   He claims that he is in another country on a business trip.  He said that  he tried to send me a gift but he lost access to his card. He is now asking to deposit more than 10k into my account and have me wire it. Is this a l classic way of scamming people? If so, is it common that they spend months creating a relationship with you  to catfish you? On the canonical isomorphism between $V$ and $V^{**}$ Homeomorphism(topological spaces) version of Cantor–Bernstein–Schroeder theorem First off, this is a question about a desktop application using Windows Forms, not an  question.  I need to interact with controls on other forms. I am trying to access the controls by using, for example, the following...  otherForm.Controls["nameOfControl"].Visible = false;   It doesn't work the way I would expect. I end up with an exception thrown from Main. However, if I make the controls public instead of private, I can then access them directly, as so...  otherForm.nameOfControl.Visible = false;   But is that the best way to do it? Is making the controls public on the other form considered "best practice"? Is there a "better" way to access controls on another form?  Further Explanation:  This is actually a sort of follow-up to another question I asked, . The answer I got was great and solved many, many organizational problems I was having in terms of keeping the UI straight and easy to work with both in run-time and design-time. However, it did bring up this one niggling issue of easily controlling other aspects of the interface.  Basically, I have a root form that instantiates a lot of other forms that sit in a panel on the root form. So, for instance, a radio button on one of those sub-forms might need to alter the state of a status strip icon on the main, root form. In that case, I need the sub-form to talk to the control in the status strip of the parent (root) form. (I hope that makes sense, not in a "who's on first" kind of way.) Why does change in speed of a wave make it refract? When a light wave enters a medium with a higher refractive index (e.g. from air to standard glass) and its speed decreases, why does that make it refract/bend?  I understand that wavelength decreases and frequency stays the same and therefore its speed decreases, but I can't find anywhere whatsoever why the speed decrease cause the wave to refract. So could someone please explain this? Getting all the combinations in an array I've taken some stock photography of lots of clear bottles, and now want to remove the background (which is white-ish, because at a pinch I could leave it...) so that the bottle becomes transparent with highlighting.  My bottles are clear with different colored liquids with multiple refraction and reflection surfaces.  I am looking for a background color subtraction effect that will allow me to get to transparent (hopefully with some sort of effect/opacity slider).  Ideas that I can't pull off yet:   Combine layer with a color fill layer (keyed off the "transparent color") in some manner to produce some output that could be used as the starting point of a layer mask Same layer combination as above, but somehow translating "pure white" to transparency.   Notes for what doesn't work (Photoshop terminology):   "Color Range" and delete (fuzzy select, but not graded/alpha) - results in harsh lines and only leaves the pure white and dark highlights and shadow refractions/reflections Magic wand selections for the same reason "Background Eraser" because although it is able to only subtract a certain color and leave "the rest", it (like all tolerance based tools) eventually hits a colour slightly outside of the range that it just won't touch.   I'll add more if I can remember what I've found CronJob not running How to enable or disable services? How to test for minimum amount of items in inventory and execute a command if true I am using the AmazingKit plugin on my Minecraft server to make inventory kits for players. In a command block I have the following command:  /tellraw @p ["",{"text":"Iron","clickEvent":{"action":"run_command","value":"_____"}},{"text":" / "},{"text":"Gold","clickEvent":{"action":"run_command","value":"_____"}}]   Which prints the following result: Iron / Gold.  When a player clicks on Iron, what command should I write where the empty space is _____ in order to check if the player has at least (>=) 20 iron ingots in his inventory and if he/she does, remove 20 iron ingots and execute /kit Basic. If the player has less than 20 iron ingots in inventory, the command won't be executed. Instead, Insufficient amount of iron ingots will be printed out.   Same applies when a player clicks on "Gold".  I'm on 1.14 version This seems like a pretty softball question, but I always have a hard time looking up this function because there seem there are so many variations regarding the referencing of char and tchar. I am running linear regression models and wondering what the conditions are for removing the intercept term.   In comparing results from two different regressions where one has the intercept and the other does not, I notice that the $R^2$ of the function without the intercept is much higher. Are there certain conditions or assumptions I should be following to make sure the removal of the intercept term is valid? How can I forward delete on iOS? Is there a way to delete text in front of the caret using the iOS software keyboard? The small wireless hardware keyboard accomplishes this with a fn+delete, so there might be a way to use multiple keys to accomplish the same task in iOS?

How to enter the Default Keyring password via the command line? Is there a way to enter the default keyring password using the command line?   For instance:  You have a remote setup of Ubuntu 10.10 thats set to auto login. You don't want to remove  the keyring password.  All right the system boots up and logs in automatically, then asks for the keyring password now at this point you can create ssh connections but you can't remote desktop.   What can you do to enter the keyring password at this point?  Also, to better clarify, this is from a remote connection using the command line. I've found some code that could add a modifier but none can set parameters like Octree.
