We have custom gradle plugins written in this infrastructure repository which we use in other repositories Example: buildscript { apply from: 'foo/bar/devinfra-buildscript.gradle', to: buildscript } apply plugin: 'devinfra' Here we are having the buildscript{} file, foo/bar/buildscript.gradle in every Git repository. I want to know if there is a way where we can apply the file directly from a infrastructure repository. So that

So I started to find a way around this and found this question: AngularJS : Prevent error $digest already in progress when calling $scope.$apply() . However in the comments (and on the angular wiki) you can read: Don't do if (!$scope.$$phase) $scope.$apply(), it means your $scope.$apply() isn't high enough in the call stack. So now i have two questions: Why exactly is this an anti-pattern? How can i safely use $scope.$apply? Another

I suppose the main problem I have with them is, I don't see what they are useful for. Whether formally correct or not, I understand Monads to be a tool that allows us to introduce side effects from computation. As they generalize program fragments from pure values to values boxed with other actions. From my shotgun "read all the papers" approach to learning about arrows, I've come across two

By pagination I mean that the result(tables) returned by the query is to be displayed on multiple pages. 回答1: you can use the different query instead (an achieve the names of the tables) like: SELECT TABLE_NAME FROM information_schema.TABLES WHERE `TABLE_SCHEMA` = 'my_db_name' LIMIT 10 回答2: mysql> pager less; mysql> show tables; 回答3: You can try following 1) SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES

Call it df : A B C 0 1 2 3 1 1 2 3 2 1 2 3 3 1 2 3 4 1 2 3 Now let's say I have a function f(A,B,C) , which in theory would take columns A , B , and C as inputs. For example, def function(A,B,C): return (A+1, B/2, C*3) This function returns a tuple, of course. Essentially, I'd like to know if I could apply function to df to get the following output: A B C 0 2 1 9 1 2 1 9 2 2 1 9 3 2 1 9 4 2 1 9 If so, how would I do that? I can't just type df

I'm looking for a good definition of its mechanics - what exactly it does, especially regarding how it 'grabs' arguments that it feeds to the function it is supplied as the first parameter. For instance this definition: apply explodes a seqable data structure so it can be passed to a function that expects a rest parameter. For example, max takes any number of arguments and returns the greatest of all the arguments. , from the 'Brave and True' book . Is there more to it
