Show the original function when logging funcName in a decorator
Preserving signatures of decorated functions
How to show $(a^b)^c=a^{bc}$ for arbitrary cardinal numbers? One of the basic (and frequently used) properties of cardinal exponentiation is that $(a^b)^c=a^{bc}$.  What is the proof of this fact?  As Arturo pointed out in his comment, in computer science this is called . I understand that once a game is in the library it cannot be removed, only hidden.  My question is, can I gift an uninstalled copy of a game to a friend?  I understand that this may be impossible due to legal issues, and that once a game is in the library it stays. I have a requirement to create triggers dynamically after a managed package is installed. I have read that the tooling API can be used to create triggers dynamically however it cannot be used in production. Is it possible to create triggers from a managed package in an org? I want to be able to create the trigger based on some user inputs. Uniform convergence for sequences of functions I have a simple skull model, to which I applied the subdivision modifier. For the most part everything works as expected, except I keep getting these weird sharp vertices and I can't seem to figure out how to flatten them.    I'm using Blender 2.8. Is this some kind of feature I can disable/enable for particular vertices? The distance between the sharp vertices and the gray outline differ.    Any suggestions please? Thank you!  EDIT: I also tried selecting as both - vertexes and edges and then applied Edge->Clear Sharp, but nothing changed. Any hints or answers to figure out the unknown value of C?

Prevent Word from Including Bullet Letter when Copying Text I'm copying quite a bit of text from Word into a text-based application, line by line.  The word text is structured like this:        Topic      a. Item A      b. Item B      When I highlight Item A, copy, and then paste into the text-based application, I get a.    Item A rather than just Item A as desired.  How can I prevent Word from including the bullet letter when copying? Is there word for this, other than know-it-all? Just wondering, if there's a word for:  One who makes it appear as if they're an expert on a subject while there are also signals (subtly or blatantly noticeable) that this person doesn't know very much on the subject or at least as much as they're acting like they do on the subject; pretending to have much knowledge on a subject matter.  I found pedantic but I don't suppose it's the right word. Haar measure on $SO(n)$ I am interested in describing the group of special orthogonal matrices $SO(n)$ by a set of parameters, in any dimension. I would also like to obtain an expression of the density of the Haar measure in this set of parameters. Could anyone help me on this or indicate a good reference? Thanks In Hitchcock's Vertigo, there is one part of the film that has never made sense to me and I believe that it was a cheap ploy to mislead the audience until the ultimate reveal (I won't spoil it here).    In this scene Jimmy Stewart watches Kim Novak enter a rooming house and afterwards sees her standing by the window on the 2nd floor.  When he enters the house and talks to the inn-keeper, she tells him that Kim Novaks's character positively never came in and even shows him her room key that is still behind the front desk.  They go up to the room and find it empty.   This scene seems to imply that the Kim Novak character may have had a ghost like quality. But given the reveal at the end she clearly does not and there was no way for her to enter the room without a key and without being seen by the inn-keeper.  If this was done by some other director I probably wouldn't have given this much thought but Hitchcock was a perfectionist (especially for this film) so I never understood the significance of this scene other than to mislead the audience (with a cheap ploy IMO).  Does anyone who is familiar with this film have a different explanation/perspective about this scene in an otherwise brilliant movie. Where to place log4j.xml Core Data NSPredicate with to-Many Relationship I am trying to pass a member function within a class to a function that takes a member function class pointer.  The problem I am having is that I am not sure how to properly do this within the class using the this pointer.  Does anyone have suggestions?  Here is a copy of the class that is passing the member function:  class testMenu : public MenuScreen{ public:  bool draw;  MenuButton&lt;testMenu&gt; x;  testMenu():MenuScreen("testMenu"){     x.SetButton(100,100,TEXT("buttonNormal.png"),TEXT("buttonHover.png"),TEXT("buttonPressed.png"),100,40,&amp;this-&gt;test2);      draw = false; }  void test2(){     draw = true; } };   The function x.SetButton(...) is contained in another class, where "object" is a template.  void SetButton(int xPos, int yPos, LPCWSTR normalFilePath, LPCWSTR hoverFilePath, LPCWSTR pressedFilePath, int Width, int Height, void (object::*ButtonFunc)()) {      BUTTON::SetButton(xPos, yPos, normalFilePath, hoverFilePath, pressedFilePath, Width, Height);      this-&gt;ButtonFunc = &amp;ButtonFunc; }   If anyone has any advice on how I can properly send this function so that I can use it later. Automatic vacuum fails with `ERROR: XX000: cache lookup failed for type 0` I've been noticing something like this popping up every 15 seconds in my server logs:  2020-01-30 21:10:30 UTC::@:[24969]:ERROR: XX000: cache lookup failed for type 0 2020-01-30 21:10:30 UTC::@:[24969]:CONTEXT: automatic vacuum of table "myschema.mytable" 2020-01-30 21:10:30 UTC::@:[24969]:LOCATION: get_typlenbyval, lsyscache.c:2036   When I manually run a VACUUM ANALYZE myschema.mytable; it runs without any error, and the error in my logs goes away.

How to avoid long nesting of asynchronous functions in Node.js How do you use script variables in psql? In MS SQL Server, I create my scripts to use customizable variables:  DECLARE @somevariable int   SELECT @somevariable = -1  INSERT INTO foo VALUES ( @somevariable )   I'll then change the value of @somevariable at runtime, depending on the value that I want in the particular situation. Since it's at the top of the script it's easy to see and remember.  How do I do the same with the PostgreSQL client psql?
