Inheriting non-implicit constructors on Apex classes If I have an abstract parent class like this:  abstract class Vehicle {     public Vehicle(Person driver) {         //     } }   and then I create a child class like this:  public class MagicCarpet extends Vehicle {     //this won't compile }   I encounter the following Compile Error:     Error: Parent class has no 0-argument constructor for implicit construction at line ... column ...   Obviously I can explicitly re-declare a constructor on the child class toget it to compile:  public class MagicCarpet extends Vehicle {     public MagicCarpet(Person driver) {         super(driver);     } }   But I feel this isn't DRY. Not sure what's actually going on under the covers here.  How can I get a constructor (other than the implicit 0-argument one) to be inherited by a child class? How to redirect STDIN of background process? In my Ubuntu, i run java application in background. I use bash script to run it and now it looks like:  nohup java -jar app.jar &amp; exit 0   The problem that i want to be able to write an input string to my application, without making it foreground, from different terminals/sessions.

Does Earth's Rotation Affect Its Shape? Why do heavier objects fall faster on hills but not in straight drops? All other things being equal, if a heavier object will roll at a higher speed down hill than a lighter one, because it's heavier with more mass, then how is it that dropped objects fall at the same speed regardless of their weight? How to find out what's accessing a particular hard drive on Windows? Possible Duplicate:          My HDD on a dock just started making noises like it's being accessed but I don't see any program accessing it.  Is there a program that shows which HDD is accessed by which program in percentages similar to how the task manager shows which programs use the most CPU? Split comma-separated values I have a function with the same name, but with different signature in a base and derived classes. When I am trying to use the base class's function in another class that inherits from the derived, I receive an error. See the following code:  class A {     public:     void foo(string s){}; };  class B : public A {     public:     int foo(int i){}; };  class C : public B {     public:     void bar()     {         string s;         foo(s);     } };   I receive the following error from the gcc compiler:  In member function `void C::bar()': no matching function for call to `C::foo(std::string&amp;)' candidates are: int B::foo(int)   If I remove int foo(int i){}; from class B, or if I rename it from foo1, everything works fine.   What's the problem with this? Practical way to implement prevention of IP Spoofing I am an undergraduate Computer Science student and was hoping to gain some knowledge of ways to help prevent IP spoofing but all the resources I have tried out elaborate this concept in a theoretical way. I want to try out my hands at one of the techniques like:      How do I simulate this whole situation in my own system were I myself am the attacker and I myself have to defend it? And once I have gained an understanding of it, then how do I start translating that into programming terms? I am stuck on how to calculate the following limit: $$\lim_{x\to\infty}x\left(\left(1 + \frac{1}{x}\right)^x - e\right).$$  Definitely, it has to be through l'Hôpital's rule. We know that $\lim_{x\to\infty} (1+(1/x))^x = e$. So, I wrote the above expression as $$\lim_{x\to\infty}\frac{\left(1 + \frac{1}{x}\right)^x - e}{1/x}.$$Both numerator and denominator tend to zero as x tends to infinity. I applied l'Hôpital's rule twice, but I got the limit equal to infinity which is clearly wrong. In the book, it says that the limit should be $-e/2$.  Any help please? Also, in case someone managed to solve it, please tell me which numerator and denominator did you apply your l'Hôpital's rule to in both cases? Thanks a lot  Also, guys can you tell me how to write equations in this forum? Thanks. \ref, make figure/table reference automatically toggle between "above" or "below" Is it possible to automatically include a reference to the position of a labeled object (Table, Figure) in text? By this I mean the following:  Say I have labeled a figure in chapter 1:  \label{fig:one}   Then I refer to it in text by using:  See Figure~\ref{fig:one}   Which produces "See Figure 1.1" as desired. I'd like to be able to have it produce: "See Figure 1.1, above" or "See Figure 1.1, below", automatically detecting whether to produce "above" or "below" depending on whether the figure will be placed above that position on the final page. Not every open set in $\mathbb{R}^n$, for $n\geq2$, is a disjoint union of countable open balls. I know that every open set in $\mathbb{R}$ can be decomposed as the union of countably many disjoint open intervals and I'm trying to show that this property no longer holds in higher dimensions. For this I'm trying to show that there is no countable, pairwise disjoint open balls whose union is the open square $(0, 1)^2 ⊂ \mathbb{R}^2$. I know that it is because of the corners, but I don't know how to write this in mathematical terms. Thanks for any help. Transferring a Windows 8 license and proper un- and reinstallation Long story short  I have two computers: a laptop and a desktop computer. Both have Windows 7 on them.  I buy the Windows 8 Pro upgrade. To see if it screws up anything, I install it on my laptop as a guinea pig. I intend to use Windows 8 for my main computer, my desktop, but I want to test it on the laptop, so I know I don’t risk losing access to my desktop and the data on it. I never use my laptop, and only used it, because it already has a Windows 7 installation on it.  The problem  At some point, I must have entered the license key on my laptop, because when I go to the activation screen on my desktop, I get this:    Uh-oh. I can’t use the key on my desktop. Now how the hell do I transfer the key from my laptop to my desktop computer?  Answers and suggestions so far  Let’s just say that I tried everything possible to get some answers on this matter. The best response I got from Microsoft is this:     To install Windows 8 on your desktop, do the following:         Uninstall Windows 8 on your laptop   Afterwards, install Windows 8 on your desktop   If it won’t activate, call product activation at (...)      I am not a fan of that last point. The error message does allude to such a solution, however:     If you’ve reinstalled Windows or made changes to your hardware recently, you may be able to use your current key.   The question  My main question is this: has anyone been in a similar situation, and if so, what did you do to resolve this?  Failing that, what is the proper way to   uninstall the Windows 8 installation on my laptop, and reinstall the Windows 8 installation on my desktop?   Ad 1  I have already tried using the “reset” feature on my laptop, but that only resulted in a new Windows 8 installation that was already activated. But which is the right way to uninstall the installation in a way that allows me to use the license key on the desktop computer?  Ad 2  Which is the proper way to reinstall the Windows 8 installation on my desktop computer? Why do I even have to reinstall it in the first place?  I won’t get around to do this, until my USB key with 3.0 support arrives in the mail, but it is going to be a while, until I find a assuaging response to the best way to go about this anyway. How to run adb and fastboot commands from Termux? When will "Present Perfect vs. Past Tense" cases be affected by culture? Regarding actions taken in the past, besides the differences those two tenses have semantically, my teacher shared that it could be a British vs American English case.   When talking about past action, British prefers present perfect because they take into account that the effect from their past action still happens until now. As for American, they prefer to state the action only. It happened in the past, so past tense it is.     I have had dinner. [British]   vs.      I had dinner. [American]   I hope to hear it from the native speakers, both British and American. What do you think about this? Is it true?  If it is, I don't think it can apply to all cases of past actions. There have to be cases when both style agree to use the same tenses. Could you please help me define the situation when this kind of difference applies and when doesn't? Combinatorics identity question Ubuntu 14.04 multi touch screen support Just installed 14.04. It seems to be converting all my screen touch gestures to mouse gestures. And it only supports one point touch. It is supposed to support ten touch points (tested with windows 8.1).  Am I missing something here? Do I have to install some kind of package? Or is it just not supported?  Test - being able to draw here: Let $f:\mathbb{R}\to\mathbb{R}$ be a map sending closed intervals to closed intervals. Prove that $f$ is continuous or find a counter example.  WLOG we just have to prove continuity at $0$ and we can also assume that $f(0)=0$ and $f(1)=1$ (by considering $x\mapsto (f(x)-f(0))/(f(1)-f(0))$ ).  I build up this question while thinking of the question . Probability question with interarrival times (Why did the chicken cross the road?) A chicken wants to cross a single-lane road where the cars arrive according to a Poisson process with rate $\lambda$. She needs at least $k$ minutes to cross the road safely, so she will have to wait until she sees a gap of at least $k$ between the oncoming cars. If the gap between the car that just arrived and the next one is at least $k$ then she starts crossing the road immediately. Let $T$ denote the random time she needs to wait by the road.  Find the expected time needed to cross the road. Can we opt for fast track service after the refusal? Last Saturday, I got a refusal from BHC due to lack of funds and my reasons to come back to India. I am planning to visit my family who are settled in the UK. I am married and planning to visit my family along with my husband. My father is sponsoring our whole trip. But we got a refusal as we didn't show much funds in our account. We thought that if my father is sponsoring, we should show his documents only. But now I have applied again with a fast track service. Will BHC will consider it under the fast track process? This time I have cleared all their doubts which they mentioned in the refusal letter.
