How can I get nameof() functionality for the parameter name of a method called The simplest way for me to describe this is in the Unit Testing context.  I have a method that accepts a parameter and asserts that parameter isn't null.  public void DoStuff(string requirementName) {      if (requirementName == null) throw new ArgumentNullException(nameof(requirementName));  }   Then I have a test that asserts this exception is thrown.  [Test] public void NullRequirementName_ThrowsArgNullException() {     var sub = new DoStuffClass();     Action doStuff = () =&gt; sub.DoStuff(null);     doStuff.Should().Throw&lt;ArgumentNullException&gt;();  }   What I want is to assert that the message of the exception contains the name of the parameter, and yet allow the parameter name in the signature of DoStuff to change and give compile time indication that the name is changed.  [Test] public void NullRequirementName_ThrowsArgNullException() {     var sub = new DoStuffClass();     Action doStuff = () =&gt; sub.DoStuff(null);     doStuff.Should().Throw&lt;ArgumentNullException&gt;().Where(ex =&gt; ex.Message.Contains("requirementName");  }   The above assertion works fine, but doesn't allow the param name to change without breaking the test at run-time. I'm looking for a simple looking syntax that effectively gives me nameof(DoStuffClass.DoStuff.requirementName)
How can you get the names of method parameters? If I have a method such as:  public void MyMethod(int arg1, string arg2)   How would I go about getting the actual names of the arguments? I can't seem to find anything in the MethodInfo which will actually give me the name of the parameter.  I would like to write a method which looks like this:  public static string GetParamName(MethodInfo method, int index)   So if I called this method with:  string name = GetParamName(MyMethod, 0)   it would return "arg1". Is this possible?

Could a website force the browser to go into fullscreen mode? Is normality testing 'essentially useless'? A former colleague once argued to me as follows:      We usually apply normality tests to the results of processes that,   under the null, generate random variables that are only   asymptotically or nearly normal (with the 'asymptotically' part dependent on some quantity which we cannot make large); In the era of   cheap memory, big data, and fast processors, normality tests should   always reject the null of normal distribution for large (though not insanely large) samples. And so, perversely, normality tests should   only be used for small samples, when they presumably have lower power   and less control over type I rate.   Is this a valid argument? Is this a well-known argument? Are there well known tests for a 'fuzzier' null hypothesis than normality?

Is the outcome the same? This is a phrase I've heard many people use, and it sounds wrong to me; e.g.:     The thing about that is, is that she might take it the wrong way.   It seems to treat "The thing [...] is"—the entire phrase—as the subject of the sentence. Of course, even if that were allowed, the comma placement would still be questionable.  I'm curious to know:   Is there a name for this wording? Is it specific to a certain dialect? Is its etymology known? Removed Python 3 and now Ubuntu Software Center, terminal and other applications don't work I am a new Ubuntu user running Ubuntu 13.04.  I've been trying to install and use a DeDRM tool, but I've been having problems doing so. I was following some directions that said I needed a version of Python 2.7, but not anything Python 3.0 or later (because 3.0 versions are missing some necessary libraries?). I tried to install Python 2.7.5.6, but it didn't work. I thought it was probably because I had the later version of Python, so I went through terminal and removed Python 3.3, so I could install the earlier version of Python.  Now that I've uninstalled Python 3.3, a lot of applications no longer work, including the terminal and the Ubuntu Software Center. I have no idea how to fix this problem now.

Android : Is there any alternative to listFile function (Android java.io.File.listFiles()) After most recent kernel update (4.15.0-44-generic) my tablet freezes whenever plugged into docking station I performed the most recent kernel update on my Dell 5290 2-in-1 earlier today.  But moments after I plug it into its docking station, the screen flickers, blanks and freezes.  The only item left on the screen is the mouse pointer, and it is stuck.   If I leave the tablet not plugged in, it runs just fine.  It seems to be the docking station that triggers the freeze.  That said, I can log into the tablet via ssh even with the screen frozen.  So the system is still running.  But if I try to reboot the tablet via the reboot command, nothing appears to happen. sudo reboot -f will reboot the system, while sudo reboot will not.  Any ideas where I should start looking to identify this problem? Permanently blocking a domain in iptables Suppose I want to block Facebook permanently. To do this, I have followed following processes:     #host -t a www.facebook.com   Sample output:     www.facebook.com has address 69.171.224.40   Find CIDR     #whois 69.171.224.40 | grep CIDR   Sample output:     CIDR:           69.171.224.0/19   To prevent outgoing access to www.facebook.com  Approach 1:     #iptables -I FORWARD -p tcp -d 69.171.224.0/19 -j DROP   Approach 2:     #iptables -I FORWARD -p tcp -d www.facebook.com -j DROP   Both Approaches work well. In approach 1, IP address may be changed so it will not block Facebook permanently. I don't know about approach 2 whether it will block Facebook permanently or not. If above approaches are not right way to block a domain permanently, how can I do it? Can I use extra wire from two separate cables to add a washing machine in a garage?
