I'm new to Ubuntu and I tried to install something and the guide I was reading says to run a command that starts with  sudo add-apt-repository   but whenever I try to use the command then it says  bash: add-apt-repository: command not found   whether I start it with sudo or not, and I can't seem to find any help anywhere else.
I’m running Ubuntu 14.04. When I run:   sudo add-apt-repository ppa:ubuntu-wine/ppa   I get the following error:  sudo: add-apt-repository: command not found   I tried to run  sudo apt-get install software-properties-common   but it shows:  software-properties-common is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
Is there some rule against ending a sentence with the contraction "it's"? I heard this lyric in a song the other day and it just sounded so wrong that I assumed it must be incorrect grammar, but I can't find any specific prohibition that applies.     That's what it's.    That rolls off your tongue with the grace of a moose in a tutu, but I can't figure out why.  There is clearly no problem with ending other sentences with a contraction. These sound fine.     I thought I could, but I can't.   Stop touching that, it will fall off if you don't.   You say that the sky is green, but it isn't.   Also, it sounds just fine if you remove the contraction:     That's what it is.   So what's up with this construction? Should it be avoided? C++ copy-construct construct-and-assign question How did the word "Bollywood" originate? As we know, American film industry is referred as Hollywood. The American film industry is called so because the film industry emerged at the place called (Correct me if I am wrong). The place adopted the name Hollywood which is informally known as Tinseltown.  But my question is not about Hollywood but the . This is widely referred as Bollywood.   From the  page of Bollywood:      Bollywood is the sobriquet for India's Hindi language film industry, based in the city of Mumbai, Maharashtra. It is more formally referred to as Hindi cinema. The term "Bollywood" is often used by non-Indians as a synecdoche to refer to the whole of Indian cinema; however, Bollywood proper is only a part of the larger Indian film industry, which includes other production centres producing films in many other Indian languages. There is no place in India called Bollywood like the Hollywood.    Many people prefer calling it as Hindi film industry and against naming film industries with wood. There are other film industries in India too in other languages. Eg: Telugu film industry is named as Tollywood, Tamil industry is named Kollywood etc.,   is the list of Hollywood inspired nicknames.  My question:   Who is the creator of the word Bollywood? Since when did the word become popular? What is the metal sheath surrounding a USB connector, and is it commonly connected? Why is there a peeking duck in my profile pic? In , you may see something odd: a peeking duck.    I've just recently uploaded this new profile picture of mine. I checked it after the upload and everything's fine. After a few hours, I opened my profile and there it is, the duck has somehow become afraid of the people viewing it.  Is this a bug, a feature, or is it just the duck?  I am about to re-upload my profile pic, but I've decided to drop first this topic to meta.  And if you're curious,  is the original picture.    ADDITIONAL: I've used the non-gravatar way to upload the picture.  ADDITIONAL 2: The problem only shows in the profile view. No problem in chat, less info profile view, and in the questions and answers.  UPDATE: Re-uploaded picture. Status normal (for now, at least). The space $C^0([0;1],\mathbb{R})$ of all continuous, real-valued functions on $[0,1]$ is not reflexive. Work the Spring There's a book that I read several years ago that I'd like to find.  However, I cannot remember enough about it to find it myself.  Neither the title nor author remain in my mind, nor any keyword or phrase that's unique enough for the Grand Google to nail for me.  Hence my desperate plea here.  In the book, there is an interstellar civilization composed of several power blocks.  The entire civilization did not fill the galaxy, but it did span several stellar systems.  Maybe 10s or 100s.  I seem to remember that one of the civilizations was a decentralized group referred to as the Brotherhood and they seemed to have been keen on preserving old learning and political ideals.  A derelict alien spacecraft from outside all of this had been discovered and at least two of the power blocks sent ships to recover it.  I don't recall if they knew at the time about the power the alien ship had, but they must have had some clue since there was some urgency in capturing this ship.  One of the ships sent to capture the Alien craft was commanded by somebody who was rather shaken up, to say the least.  He had had some big trauma in his past (like... the last ship he captained was annihilated with all hands.) so he was kinda bummed out about things and wasn't really putting his heart into getting this done.  He was assisted by the ship's AI who had a lot of soul-to-soul chats with the captain, and at one point almost relieved him of command because he was just not getting the job done.  I think the ship's name was Boaz.  These were the "good guys".  There was at least one other ship sent from the "bad guys."  The alien craft had some remarkable powers.  The interior volume was apparently infinite and the operators could see and manipulate anything in the universe.  There might have been some example given where all the rats somewhere were found and disposed of.  Whoever had control was tempted by the ole absolute power corrupts absolutely problem, but nobody but nobody could stop them because of their power.  They could eat and multiply within the ship and become real bad-asses.  But alas... (or hurray, depending upon which side you're one) everything fails eventually, and whoever controlled the ship would eventually succumb to some horrible end.  Whereupon the ship became derelict again until some other lucky race found it and repeated the cycle.  The ship had an AI that was real interested in taking the power for itself, but there was some mechanical, spring-loaded, mechanism outside of its control that needed to be worked in order to execute power.  The AI apparently never figured out how to "work the spring" and this made him crazy angry.  The ending is equally foggy for me.  I'm pretty sure the good guys got the ship.  They agonized over what to do with it.  Apparently it was indestructable and nobody wanted to taste the temptation of all that power.  In the end they dumped it on the surface of a neutron star.  There it sat forever more, probably with the crazy AI really pissed off about being there.  If you've read this book, you'll recognize it immediately from these clues.  I'm looking forward to finding out the name of this book.  Thanks! Integrate JavaScript in JSF composite component, the clean way Why is it that we have to use the gerund form for the first example? I have been told that it is not grammatical to use the infinitive form.  For some verbs, it's okay:     I wanted to study English.   I had to study English.   I needed to study English.   I tried to study English.   I traveled to study English.   But, for some verbs, it's incorrect:     I ended up to study English.     Why is that the case? Is there a word which describes terms that are spelled like a particular pronunciation? Some examples: &quot;never&quot; might be written as &quot;neva&quot; &quot;I don't know&quot; is sometimes written as &quot;iono&quot; or &quot;I dunno&quot; on various internet media. My question is: is there a word for this particular technique of spelling a term in the way it is (sometimes) pronounced? dpkg: error: cannot scan updates directory `/var/lib/dpkg/updates/' I want to install a package in Ubuntu 14.04, but every time I run the ./configure command it gives me this error:  E: Cannot get debconf version.

It may have been published quite a few years before I read it, I don't think it was new at the time. I borrowed the novels from the local library, but I can't find them in its catalogue. I think the covers were fairly dark and plain, though there may have been some artwork on them. There was a totalitarian empire that controlled most planets, possibly ruled by a queen. There was no mention of Earth, the solar system or other real planets, the setting was completely fictional. There were people with psychic/psionic powers, referred to as something like "psi". These people were second-class citizens or slaves. Spaceships were used to travel between worlds. I'm not sure what kind of FTL technology they had, if any. Beyond the edge of the empire was some kind of "dark space", where there was no light. There were some horror themes: When travelling in dark space in one of the novels, a ships crew experienced strange thoughts and hallucinations. I remember finding this quite scary at the time.   Does anyone know which series this could be?  This isn't a duplicate of , since the two questions are about different parts of the same series (the first and second episodes).

How to disable Macbook Pro internal display when using external monitors I have a Late 2011 Macbook Pro 13" (running Lion - OS 10.7.4) which I use with a dual external monitor setup. I have two 21" LCDs that I use as external monitors. One uses the built in Mini Display Port on the Macbook Pro and the other is connected via a USB to DVI adapter (Diamond DVILink).  The problem I am having is with the 13" built in display of the Macbook Pro. I would like it to remain closed and unused (I prefer the dual monitors at same resolution), however I cannot seem to "disable" the display in the display preferences applet. So even though the Macbook Pro lid is closed the operating system still makes use of the display, even though the apple logo on the back of the display is unlit. I have tried to move the laptop screen off out of the way in display preferences but I find when I "sleep" my setup that any applications that remain open move to the laptop screen. This makes it difficult to locate the application windows when resuming from sleep.    Does anyone know of a way to disable the laptop built in display so it is not seen by the OS when external monitors are being used? Trichromelibrary was suddenly downloading from Google Play Store "Calling dibs" - what does it imply? The term "to have dibs on something" or "to call dibs on something" plays a recurring role in American film and television (e.g. ), so it gets exported a lot.   describes "dibs" as     [...] a common, "informal" convention to reserve or declare full or partial ownership of a community resource, such as a chair [...]   From the usages in the media I have seen, this convention also seems to contain some moral concept which is not described in dictionaries. For me, it looks like by calling dibs (or ), the caller actually receives the (implicit, moral) right to that resource, and this typically goes undisputed by their rivals.  Can you confirm the existence of this concept? Is this something that varies between groups of people (or maybe between regions), or is there a concensus on how to respond to this? drupal 7 + services 3 - inserting nodes with select fields I'm using Drupal 7 + Services 3 to create nodes with POST and JSON.

I have a code that loops through all the Sites and Webs in a web application.  My code uses for..each loop to navigate through each site and web object.  I was wondering if we are required to dispose the SPWeb and SPSite objects when used inside a loop.  Codes:-  foreach (SPSite thisSite in siteAuditWebApplication.Sites) {  //My operation here  }  Similar to the above code I also have some part of code that loops through all the Web and Lists.  Do we have any best practice for disposing objects inside the loop,  or do i really need to take care about disposing the objects?  Thanks in Adv.. Sudhir
