Does the Great Old One warlock's telepathy from the Awakened Mind feature take an action? Does the Great Old One warlock's telepathy from the Awakened Mind feature take an action?  It doesn't seem too clear to our group and we have basically ruled it as equivalent to talking. Ubuntu 19.04 problems install upgrades Excel multiple FIND formula I am no expert with excel so any help is appreciated!   I am trying to make one cell do multiple searches within another.  I know that to search one cell for a specific word you would use  =FIND(Blue,C2)   But I need to find multiple different words in one cell. Heres an example of what im trying to do:    I need to show all the allergens in the ingredients cell eg peanuts, gluten, milk, sesame seeds etc   How do I get the result to list all the allergens?   I know that I can do a single find function in separate cells and then concatenate them, but there must be a more simple way?  Thanks Limiting Length of Input in JTextField is not working Installing VMware on 18.04: Failed to build vmmon Is it correct to say I electrocuted my friend if he was only injured by electricity? (clickable)  Mainad has a valid height and width, however it isn't shown like subad1/subad2. Which are in essence exactly the same! (just a different background image).  Firebug shows my div as greyed out for some weird reason. Replacing the contents of mainad with just some text doesn't solve the problem (problem isn't related to inner elements)..   What's going on?! :( Rich Snippets not working (and working at the same time?) How can I prove that all rational numbers are either terminating decimal or repeating decimal numerals? I am trying to figure out how to prove that all rational numbers are either terminating decimal or repeating decimal numerals, but I am having a great difficulty in doing so. Any help will be greatly appreciated. Geometric interpretation of $\frac {\partial^2} {\partial x \partial y} f(x,y)$ Are there any geometric interpretation for the second partial derivative? i.e.  $$f_{xy} = \frac {\partial^2 f} {\partial x \partial y}$$  In particular, I'm trying to understand the determinant from  for determining whether a critical point is a minima/maxima/saddle points:  $$D(a, b) = f_{xx}(a,b) f_{yy}(a,b) - f_{xy}(a,b)^2$$  I have no trouble understanding $f_{xx}(x,y)$ and $f_{yy}(x,y)$ as the of measure of concavity/convexity of f in the direction of x and y axis. But what does $f_{xy}(x,y)$ means? Edit:  Of course my real code doesn't look exactly like this. I tried to write semi-pseudo code to make it more clear of whay I wanted to do.  Looks like it just messed things up instead.  So, what I actually would like to do is this:  Method&lt;Interface1&gt;(); Method&lt;Interface2&gt;(); Method&lt;Interface3&gt;(); ...   Well ... I thought that maybe I could turn it into a loop using reflection. So the question is: How how do I do it. I have very shallow knowledge of reflection. So code examples would be great.  The scenario looks like this:  public void Method&lt;T&gt;() where T : class {} public void AnotherMethod() {     Assembly assembly = Assembly.GetExecutingAssembly();      var interfaces = from i in assembly.GetTypes()     where i.Namespace == "MyNamespace.Interface" // only interfaces stored here     select i;      foreach(var i in interfaces)     {         Method&lt;i&gt;(); // Get compile error here!     }       Original post:  Hi!  I'm trying to loop through all interfaces in a namespace and send them as arguments to a generic method like this:  public void Method&lt;T&gt;() where T : class {} public void AnotherMethod() {     Assembly assembly = Assembly.GetExecutingAssembly();      var interfaces = from i in assembly.GetTypes()     where i.Namespace == "MyNamespace.Interface" // only interfaces stored here     select i;      foreach(var interface in interfaces)     {         Method&lt;interface&gt;(); // Get compile error here!     } }   The error I get is "Type name expected, but local variable name found". If I try  ...     foreach(var interface in interfaces)     {         Method&lt;interface.MakeGenericType()&gt;(); // Still get compile error here!     } }   I get "Cannot apply operator '&lt;' to operands of type 'method group' and 'System.Type'" Any idea on how to get around this problem? Salesforce Toolkit for .Net with silverlight 5 I am creating a application with Silverlight 5 in which I have to communicate with Salesforce APIs.  Currently I used Salesforce toolkit for .net (version 1.2.1) by I am gettting error after using authentication method as -     The base class or interface 'System.Object' in assembly   'System.Runtime, Version=4.0.0.0, Culture=neutral,   PublicKeyToken=b03f5f7f11d50a3a' referenced by type   'Salesforce.Common.AuthenticationClient' could not be resolved.   System.runtime dll is referenced my application.   And Latest version of toolkit is even not installing in application. There is some compatibility issue with silverlight 5.  As per github and blogs Salesforce Toolkit is compatible with Silverlight 5. I installed it using nuget package manager.  Any idea to fix this ?  Thanks, Is it possible in PHP to do something like this? How would you go about writing a function? Here is an example. The order is the most important thing.  $customer['address'] = '123 fake st'; $customer['name'] = 'Tim'; $customer['dob'] = '12/08/1986'; $customer['dontSortMe'] = 'this value doesnt need to be sorted';   And I'd like to do something like   $properOrderedArray = sortArrayByArray($customer, array('name', 'dob', 'address'));   Because at the end I use a foreach() and they're not in the right order (because I append the values to a string which needs to be in the correct order and I don't know in advance all of the array keys/values).  I've looked through PHP's internal array functions but it seems you can only sort alphabetically or numerically. To prove that $f_n(x) = \frac{nx}{1+n^2x^2}$ does not uniformly converge to $f(x) = 0$ on $[0,1]$ My Approach. To prove the given statement it is sufficient to show that $$\exists \epsilon &gt; 0, \exists x \in [0,1], \forall N \in \mathbb{N}, \exists n &gt; N $$ $$ \Rightarrow | f_n(x) - f(x)| &gt; \epsilon$$    Let $\epsilon = \frac{1}{10}, x = \frac{1}{n}, n =N+1$. Hence $| f_n(x) - f(x)| = \frac{1}{2} &gt; \epsilon = \frac{1}{10}$. Hence, we have shown for every $N \in \mathbb{N}$, how to choose $n$ such that $| f_n(x) - f(x)| &gt; \epsilon$. Thus, $f_n(x)$ does not converge uniformly on $[0,1]$.    Is there any logical flaw or wrong steps in my proof. Any help would be appreciated. I am trying to use a Bluetooth headset on an Ubuntu PC. I am able to connect phone to pc via BT. I can stream music to PC. But cannot hear call audio. I have checked in Android phone logs, and BT sco link is established. But when making a call or virtual call (play audio through sco path in Android phone) the audio is not audible in PC headset. SCO packets are NOT appearing in btmon logs either. Anyone successfully done this?  version- ubuntu 16.04 Installed- bluez, ofono, pulseaudio pactl sink: Name- bluez_sink.22_22_8E_DE_B9_2B,             Name: alsa_output.pci-0000_00_1b.0.iec958-stereo pactl source: Name-bluez_sink.22_22_8E_DE_B9_2B.monitor               Name: alsa_input.pci-0000_00_1b.0.analog-stereo Novel about interstellar war: Both sides win, both sides think they lost I recall reading this novel in the &rsquo;90s; my recollection is that the author was better-known for bad fantasy than for SF (but the SF of his that I&rsquo;d read was better than his fantasy).  The story opened in media res just before a battle was joined; there is a dialogue between the captain of one of the ships and one of his crew. We never see the actual battle; we instead see the conquest of Earth by the aliens - and the conquest of the alien homeworld by Earth.  It is slowly revealed that the two sides contrived a way to both avoid the destruction of actual war, and solve their respective worlds&rsquo; respective problems of overpopulation, infrastructure decay, et multae ceterae. We also see that the solution was that the conquering aliens were secretly selecting Earthmen to rule their homeworld, while the humans were selecting aliens to rule Earth.  About halfway through, there is suddenly a third world that must be &lsquo;conquered&rsquo; and brought into the network. The plot gets complicated after that. In  (2014) the human race seemed to be facing pretty poor odds until they discovered a convenient wormhole placed by an unknown entity expressed as "they". Later in the movie, we discover that       "they" are actually the human race in the future, reaching back in  time to save itself.   The end of the movie gets a little wild on the physics end, and I'm happy to take that ending as is - no need for it to make sense - but one very basic detail does bother me:  How could the human race have gone back in time to save itself from circumstances that would have caused us to go extinct without our own help (the convenient wormhole)? How could I retrieve the exact duplicate value from conditionally formatted list that highlight duplicates? I have imported a webpage table in to Google Sheets. It frequently being updated. A series of calculations has been conducted on the sheet named Shawn Of the link spreadsheet.  I have filtered the my desired results into the Calculation sheet of that linked document... which is in columns A5:A. I then applied =ARRAYFORMULA(if(A5:A200=&quot;&quot;,,A5:A200*{12,13,37,101,111})) in columns B5. The Results of the formula extends from B5:F. This results from a5:F was subsequently conditionally formatted to highlighted duplicates in the aforementioned, i.e. a5:f using the lists of values in K5:K and I5:5. In Columns A5:F, is it possible to generate/place values in the range A5:f with matching name of states and aligned values in J5:K and H5:I? How can I convert a Unix timestamp to DateTime and vice versa? There is this example code, but then it starts talking about millisecond / nanosecond problems.  The same question is on MSDN, .  This is what I've got so far:  public Double CreatedEpoch {   get   {     DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();     TimeSpan span = (this.Created.ToLocalTime() - epoch);     return span.TotalSeconds;   }   set   {     DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();     this.Created = epoch.AddSeconds(value);   } } Best choice between using \\ or leaving space after each paragraph to end the paragraph Here is the thing, I have always used a blank space between paragraphs in order to tell latex that there is a new paragraph. But there is someone I work with very often that keeps using \\ to break a line after a paragraph...  This is really annoying so I wanted to know if there is a real advantage of using \\ over just leaving a space.  Note that I am not referring to the paragraph environment, but to the simple term paragraph.
