Let's say I download Uncharted 3 because it is on this month's rotation, when the month ends and a new rotation begins, will I still be able to play uncharted?  Can I keep a "free rotation" game forever by being a Playstation Plus member?
I bought a three months membership for PlayStation Plus some time ago. This membership has already expired. While it was active, I got the classic PSOne Resident Evil titles for free. Will I be able to re-download them now without having to purchase a new PSPlus membership?
Are there any drawbacks to legacy BIOS as opposed to UEFI? Are there any drawbacks to installing Ubuntu 13.10 (and soon 14.04) in Legacy BIOS instead of UEFI?  I have installed 13.10 64bit in Legacy by mistake and was just wondering if it would hurt anything to simply leave it there as is?  EDIT  Everything seems to be running just fine in Legacy and all my drivers work. How can I remove a trailing newline? What is the Python equivalent of Perl's chomp function, which removes the last character of a string if it is a newline? How to run Unix shell script from Java code? It is quite simple to run a Unix command from Java.   Runtime.getRuntime().exec(myCommand);   But is it possible to run a Unix shell script from Java code? If yes, would it be a good practice to run a shell script from within Java code? Prove that $1+\frac{1}{3}+\frac{1\cdot 3}{3\cdot 6}+\frac{1\cdot 3\cdot 5}{3\cdot 6 \cdot 9}+.........=\sqrt{3}$ Prove that $$1+\frac{1}{3}+\frac{1\cdot 3}{3\cdot 6}+\frac{1\cdot 3\cdot 5}{3\cdot 6 \cdot 9}+.........=\sqrt{3}$$   $\bf{My\; Try::}$ Using Binomial expansion of  $$(1-x)^{-n} = 1+nx+\frac{n(n+1)}{2}x^2+\frac{n(n+1)(n+2)}{6}x^3+.......$$  So we get $$nx=\frac{1}{3}$$ and $$\frac{nx(nx+x)}{2}=\frac{1}{3}\cdot \frac{3}{6}$$  We get $$\frac{1}{3}\left(\frac{1}{3}+x\right)=\frac{1}{3}\Rightarrow x=\frac{2}{3}$$  So we get $$n=\frac{1}{2}$$  So our series sum is $$(1-x)^{-n} = \left(1-\frac{2}{3}\right)^{-\frac{1}{2}} = \sqrt{3}$$  Although I know that this is the simplest proof, can we solve it any other way someting like defining $a_{n}$ and then use Telescopic sum.  Thanks. I'd like to see the full How-To on how to use manual partitioning during Ubuntu installation. The existing guides (at least those I found here) cover only automatic part and leave untouched the manual part (or extremely short and contain no pictures).  I'd like to cover such situations:     If your disk contains other systems: Dynamically update a graphic object in Mathematica Proving $T$ and $U$ are equal if I know $(X,T)$ and $(X,U)$ are hausdorff and compact This question is from Wayne Patty Exercise 4.2  Let $T$ and $U$ are Topologies on set X. Suppose $ (X,T) $ and $(X,U)$ are compact Haurdsorff Spaces. Prove that $T=U$ or $T$ is not a subset of $U$ or $U$ is not a subset of T.  I thought of proving it by this way: Assuming that if $T$ is a subset of $U$ or $U$ is a subset of $ T$ then $T=U$ must be true. But I was unable to think on how to use compactness or hausdorff property and was unable to proceed. Well, also this question was asked before on this website. But I am unable to understand how the solution will work despite trying to understand it for a fair amount of time as it was just outlined. So, I am looking for a detailed solution. How do we prove that something is unprovable? HTML encoding strikes again (but with a twist) - Chat messages inbox notifications aren&#39;t looking good Invalid characters for XML parsing in posthistory.xml from Stack Overflow We got the April 2011 data dump from Stack Overflow and, while trying to put everything into a database, we got      SyntaxError: reference to invalid character number: line 1105549, column 5445   in the middle of the posthistory.xml file. It seems that there are sets of characters (&amp;#xC I believe) within a few posthistory entries which break our XML parser.  Is there a solution besides manually changing all the C's? Guaranteed lifetime of temporary in C++? Does C++ provide a guarantee for the lifetime of a temporary variable that is created within a function call but not used as a parameter?  Here's an example class:  class StringBuffer { public:     StringBuffer(std::string &amp; str) : m_str(str)     {         m_buffer.push_back(0);     }     ~StringBuffer()     {         m_str = &amp;m_buffer[0];     }     char * Size(int maxlength)     {         m_buffer.resize(maxlength + 1, 0);         return &amp;m_buffer[0];     } private:     std::string &amp; m_str;     std::vector&lt;char&gt; m_buffer; };   And here's how you would use it:  // this is from a crusty old API that can't be changed void GetString(char * str, int maxlength);  std::string mystring; GetString(StringBuffer(mystring).Size(MAXLEN), MAXLEN);   When will the destructor for the temporary StringBuffer object get called?  Is it:   Before the call to GetString? After GetString returns? Compiler dependent?   I know that C++ guarantees that a local temporary variable will be valid as long as there's a reference to it - does this apply to parent objects when there's a reference to a member variable?  Thanks. I've noticed something while trying to prove the properties of parallel lines, and the properties that a triangle has 180 degrees. To prove the properties of parallel lines, such as alternate angles, you need to use the property that a triangle has 180 degrees. To prove a triangle has 180 degrees however, you need to use the properties of parallel lines. This really bothers me because of how circular it is. They are both reliant on each other to be true, and do not logically show, without being reliant on each other, why triangles have 180 degrees, and why parallel line properties are true.   So what I hoping for here is a way to prove parallel line properties without using the fact that a triangle has 180 degrees, or a way to prove triangles have 180 degrees without using parallel line properties. This way, things will be logical to me, and make sense.   Thanks in advance. I have asked this question before  The first guy solved it in a way, but  i would like to know is there any efficient way to do so, because i did the same for N = 13 and N = 15  which took long time.  This problem is from a pen and paper test, ZIO-2018 Can i solve it with an efficient algorithm, well i am pretty beginner in algos, so if there is one kindly descibe it how can i do so?  Thank you Hyphen or no hyphen when modifying an adjective with a quantity? What is PECS (Producer Extends Consumer Super)? Restore default apt repositories in sources.list from command line I am looking for the best method to restore /etc/apt/sources.list to default from the command line.  Is there no way to reference the source code of the package which generates this file or something like that? I want a trusted and version-independent way of restoring this file.  Solutions Ruled Out  Before you mark this as a duplicate, note that I have reviewed  already. It is only applicable if you have the Ubuntu GUI available. This question is specific to the command line.  I have also reviewed  where the accepted solution is someone pasted the contents of their sources.list file. This is not an appropriate way to restore the file as the intentions of the person providing the file contents cannot be verified and the file is subject to change with new releases.  I checked out the , but this is also not from Ubuntu so I do not plan to use it. Which meta am I supposed to post on? I'm mostly active on  and we have a separate . Most of my questions on IT Security meta have answers with links here. So my question is, where am I supposed to post what i.e. feature request, bug report, behavior questions? How can I make Ubuntu 18.04 / 18.10 desktop use Unity (be like Ubuntu 14.04)? I recently installed Ubuntu 18.04 and I'm not keen on the desktop environment. I want the desktop env. I used to have in Ubuntu 14.04. How can I get it?  I've attempted to use , but when I try to install the Unity's 7.2.5 version using the command:  apt install unity=7.2.5   it gives me   E: Version '7.2.5' for 'unity' was not found   For sure I need to add a PPA for this, but which one!? What are the salary and perks of Captain America? Brooklyn is Captain America's home, but times have changed since he was kid 8-9 decades ago. He can't afford a house there, now. This thing really troubled me when he said it in Avengers: Age of Ultron. I mean, I really became sympathetic, despite it being intended for fun.  What's the salary Captain America collects from (fallen) S.H.I.E.L.D. and/or Tony's Avengers organization? Can't they gift him a house in Brooklyn? I mean, he is one of Earth's mightiest heroes who help saved the world lots of times. Is it possible to upgrade a BGA 1224 CPU? I want to upgrade the CPU of my T430s laptop from i7-3520M to i7-3632QM. I'm sure i7-3632QM is supported (same socket (BGA1224), same TDP (35W) and microcode found in BIOS (306A9.PAT)).  So my question is: 1) is it possible to de-solder the current CPU without damaging it, and to solder the new CPU without damaging it and the motherboard ? 2) if so, what tools are necessary? who can do that at a reasonnable cost?  Until now, I was unable to find anyone able (or willing) to do that (I'm located in France, and I have tried a local fablab, electronics shops, TV repair shops, ...). Any hint would be appreciated.
