Have a look at . It's well structured, it's got 200+ votes and the accepted answer also has 200+ votes. Even so it's been protected by 'Community' for low-quality answers. I don't know about you, but that does not look like it has any low-quality answers. They may be short but they are concise and well-thought.      Obviously if you are being asked which you use in an interview, you say IList, smile, and both look pleased at yourselves for being so clever. Or for a public facing API, IList. Hopefully you get my point. - part of an answer by Arec Barrwin   That is funny, not low-quality. What is with the 'protection'? Is it autonomous and if so, shouldn't it be fixed? If not, why would these answers be classified as low-quality?
There are a few "automatically protect questions" requests out there, but I'd like to add another twist.  I'd like to request that questions that have three or more deleted answers by users with &lt;50 rep be automatically protected.  The reasoning behind this is that we have lots and lots of "not an answer" flags in the mod queue.  But we cannot protect a question from the mod queue, so we have to open each answer, evaluate if the question needs protecting, then protect it.    This process takes a long time, and can definitely be automated, as the only thing you really need to check is how many new users are posting non-answers or are spamming their awful products.
What is the name of this Ubuntu program? A couple month ago I installed a bunch of clipboard manager programs in Ubuntu, tried them out and then removed them. I must have missed one of these and now it keeps bug me in my daily usage. I need some help to identify the name of this program because the program itself provides very limited information.  This clipboard program has below characteristics: 1. It occupies hotkey Ctrl+;. When I press this hotkey, the clipboard history will pop out. It happens in bash, Chrome, Eclipse IDE, and etc, wherever it is text inputable. This is kind of annoying because it overrides my other hotkeys inside these applications. 2. Very laconic UI. Like below picture, with only a line "Select to paste", then listing out the clipboard history. There is no program information whatsoever. Right clicking on it and no menu are shown at all.      So far I have tried below ways to identify this program: 1. Browse system monitor for processes with names that could be correlated. 2. Browse through my installation log (dpkg.log) to find my installation history. Without luck, the log is lost. But I was not successful. Sometimes I see a comma after the proper name:     Hello Mr. Black,      In order to give you....   But my native language is not English and I think that the comma in this phrase should be placed before the proper name:      Hello, Mr. Black.      In order to give you....   What is the correct punctuation in English? How does a  work? If seen from the outer side, we can see through thinking it is transparent, while if seen from the inside, the glass acts as a mirror. How? I'm working with some code that widely uses the idiom of returning a pointer to a static local variable.  eg:  char* const GetString() {   static char sTest[5];   strcpy(sTest, "Test");   return sTest; }   Am I right in thinking that this is safe?  PS, I know that this would be a better way of doing the same thing:  char* const GetString() {   return "Test"; }   Edit: Apologies, the function signature should of course be:  const char* GetString(); has played the role of Wolverine as a major character in various X-Men films since 2000 and contributed highly to the brand of the X-Men movie series. But is he playing the Wolverine character for the last time in Logan?  I am getting to know from my friends that  is the last movie in which he is playing Wolverine and they all say that this is his last contracted film.  Are these rumors true? Is there any official information that confirms that this is Hugh Jackman's last movie as Wolverine? Why is the company email still "at stackoverflow" Proving $\sum\limits_{k=1}^{n}{\frac{1}{\sqrt{k}}\ge\sqrt{n}}$ with induction I am just starting out learning mathematical induction and I got this homework question to prove with induction but I am not managing.  $$\sum\limits_{k=1}^{n}{\frac{1}{\sqrt{k}}\ge\sqrt{n}}$$  Perhaps someone can help me out I don't understand how to move forward from here: $$\sum\limits_{k=1}^{n+1}{\frac{1}{\sqrt{k}}+\frac{1}{\sqrt{n+1}}\ge \sqrt{n+1}}$$ proof and explanation would greatly be appreciated :) Thanks :)  EDIT sorry meant GE not = fixed :) My ListView (of my ViewFilipper) fills the parent and buttons on the bottom get hidden Voltage at soldering iron tip, should I be worried? I discovered that my soldering iron has voltage at the tip and it seems to increase the hotter the iron gets. Should I be worried? I've been trying to repair an old CRT monitor and I'm worried the issues I've been having are due to this cheap iron damaging something.  How to meassure voltage of an soldering iron tip? Where to put probes? I am a Indian citizen in the United States on a F-1 visa.  For the summer break, I am traveling (round-trip) from Chicago to New Delhi via Dusseldorf-Frankfurt by Lufthansa airlines. My onward Journey would be on July - 8 and return Journey on Aug - 11.  My layover will be of 1 hour 10 mins in Frankfurt and 3 hours in Dusseldorf.  I would like to know if I require Category A or Category B Visa. If not, what type of visa do I require for the Schengen visa for my transit. How I can apply for the same?  I tried to find slots in German consulate but all slots are full before my departure date. If I don't get the Schengen visa, I cannot travel and will loose all the fare (since my ticket is a non-refundable ticket). Is there any other way I can tackle this situation. c stdout print without new line? Appropriate data transformation How do I integrate the following $$\int \frac{dx}{\sin^3 x + \cos^3 x}$$ ?  It appears that I am supposed to break this up into $(\sin x + \cos x)(1-\cos x \sin x)$, but the next thing to do is not apparent to me. SQL Server 2008 R2 SP1  My company uses the Great Plains (GP) financial system with several customizations.  Our Value-Added-Reseller (VAR) for GP has setup most of these customizations in a separate database from the GP data called DYNCUSTOM.  In the DYNCUSTOM database is a View that is merely a SELECT * FROM a table in the GP company database (called PARTS).  I was approached by a user having problems trying to select on this view.  The error he was getting:  Msg 229, Level 14, State 5, Line 2 SELECT permission denied on object 'BM010415', database 'PARTS', schema 'dbo'   I looked at how his login was mapped and he had a database user in the DYNCUSTOM database belonging to a database role that was granted select on the view.  However, he did not have a database user in the PARTS database.    Usually the intent of a view is so that one can grant select permissions on the view without exposing access to the underlying table.  With SQL Server however, if the view crosses databases does it then change the security context being used?  Therefore, the user would also need a database user in the PARTS database as well as granted select access to the underlying table? The $n$ complex $n$th roots of a complex number $z$ Suppose $z$ is a nonzero complex number, so $z=re^{i\theta}$. Show that there are only $n$ distinct complex $n$-th roots, given by $r^{1/n}e^{i(2\pi k+\theta)/n}$ for $0\leq k\leq n-1$.   My proof: Let $z=re^{i\theta}\in\mathbb{C}$ and $a\in\mathbb{C}$ s.t. $a^{n}=z$. Let $a=\rho e^{i\varphi}$. Then, $a^{n}=(\rho e^{i\varphi})^{n}$. Setting $\rho^{n}e^{i\varphi n}=re^{i\theta}$ and rewriting in polar form, we get $$\rho^{n}(\cos(n\varphi)+i\sin(n\varphi))=r(\cos(θ)+i\sin(\theta)).$$ Thus $\rho^{n}=r$ $\rightarrow$ $\rho=r^{1/n}$ and $n\varphi=\theta\rightarrow\varphi=\theta/n$. Thus the roots of $a\in\mathbb{C}$ have the form $$r^{1/n}(\cos(\tfrac{\theta}{n})+i\sin(\tfrac{\theta}{n}))=r^{1/n}(\cos(\tfrac{\theta}{n}+2\pi j)+i\sin(\tfrac{\theta}{n}+2\pi j))$$ for some $j\in\mathbb{Z}$ due to the periodicity of trig functions. Then, $$r^{1/n}(\cos(\tfrac{\theta}{n}+2\pi j)+i\sin(\tfrac{\theta}{n}+2\pi j))=r^{1/n}e^{i\left(2\pi j+\tfrac{\theta}{n}\right)}=r^{1/n}e^{i(\theta+2\pi k)/n}$$ for $0\leq k\leq n-1 ,j=nk\in\mathbb{Z} $.  I feel like there could be a more concise way to put this. Bridged interfaces and VLAN tags I am developing an offline installer for all versions of Ubuntu, and I need Ubuntu's default installed packages list. Is there a way to get this information from any server (web server)? Any script to fetch any Ubuntu version's default installed packages list.  I will give the Ubuntu version, and the script will fetch the packages list.  Note: I need at least a server address. I can write a script for this. Is there an official Marvel Cinematic Universe viewing order? How can I balance uniformity of style files against modularity? I'm using Windows/TeXworks/MiKTeX, and I would like to have one style file I can use anywhere in any document in my top-level folder. If I want to add a new command or renew an old one, I'd like that to be available in all documents recursively contained in my top-level folder. I have a very hierarchical structure to my top-level folder. So this would seem to point to having a single file that TeXworks knows about. Could I add a path in Preferences -> Typesetting -> Paths for TeX and related programs? I've tried that, possibly superficially, without any success. Adding the correct folder to the Windows PATH variable doesn't seem to do the trick, either.   On the other hand, suppose I want to send someone a TeX file? It would be nice in such circumstances to be able to have the style file in the same folder as the TeX file. If I do that, how could I ensure that it's always up-to-date? Is there a script available somewhere that could take my master style file and push it down to all pre-existing lower-level locations?   Just to reiterate: I want uniformity of my style files in my very hierarchical folder structure. However, I would also like modularity, in that each folder is self-contained. How can I achieve that?  Also, out of curiosity, since I may acquire a Linux computer soon, how would I do this in, say, *ubuntu with TeXlive? Is it correct to say "I slump/slumped on/onto the stool/barstool?" I wrote this sentence: "I buy a bottle of beer and slump on/onto the last stool."  A native English speaker told me that "slump" doesn't work here. That you can't slump on a bar/barstool.  Is this correct? If so, why?
