Consider the following example: public class Example { public int a, b, c, d; public void doIt() { a = b + 1; c = d + 1; } } If this class is used is a single-threaded application, then the observable behavior will be exactly as you would expect. For instan...

Convert from wide form to long form Load data USArrests from datasets. data("USArrests") head(USArrests) Murder Assault UrbanPop Rape Alabama 13.2 236 58 21.2 Alaska 10.0 263 48 44.5 Arizona 8.1 294 80 31.0 Arkansas 8...

Convert from long form to wide form To recover data from the previous example, use dcast like so. DTc <- dcast(DTmu, State + UrbanPop ~ Crime) This gives the data in the original wide form. State UrbanPop Murder Assault Rape 1: Alabama 58 13.2 236 21.2 2:...

int val = 10; // val will be printed to the extreme left end of the output console: std::cout << val << std::endl; // val will be printed in an output field of length 10 starting from right end of the field: std::cout << std::setw(10) << val << std::endl; This ...

Here is a basic class documentation example: /// Class description class Student { // Member description var name: String /// Method description /// /// - parameter content: parameter description /// /// - returns: return value description func say...

SAML specifies three key roles: The Identity Provider (IdP) The party which provides and maintains the identity of the users. This can be a directory service like ADFS or a custom database solution. The Service Provider (SP) The Service Provider is the actual service which the user tries...

With all the requests and assertions going back and forth, it can be cumbersome to debug issues with your SAML claims and assertions. As within SAML a core principle is not needing a direct connection between the IdP and the SP, the user's browser acts as a message carrier between the two. Because ...

When a new documentation tag is created, StackOverflow automatically generates an introductory topic, acting as a placeholder for the first actual topic. The introductory topic contains placeholder texts and pointers to point contributors in the right directions for helping expanding on the new doc...

@at-root directive can be used to localize variables. $color: blue; @at-root { $color: red; .a { color: $color; } .b { color: $color; } } .c { color: $color; } is compiled to: .a { color: red; } .b { color: red; } .c { color: blue; }

Define the variables within a formula field: Shared NumberVar x := 1000; Shared NumberVar y; Assigning the values is optional. To display the variable in a second formula later on in the report, the call is nearly identical: Shared NumberVar x; x

Ucto is a rule-based tokeniser for multiple languages. It does sentence boundary detection as well. Although it is written in C++, there is a Python binding python-ucto to interface with it. import ucto #Set a file to use as tokeniser rules, this one is for English, other languages are availabl...

In many application it is necessary to compute the function of two or more arguments. Traditionally, we use for-loops. For example, if we need to calculate the f = exp(-x^2-y^2) (do not use this if you need fast simulations): % code1 x = -1.2:0.2:1.4; y = -2:0.25:3; for nx=1:lenght(x) for n...

Traditionally, you can use routing to map an the request with the Routing Component who handled request and response parameters by HttpFoundation Component. Additionally, a custom route parameter can be created by using the FOSRestBundle to extends the default functionalities of the Routing Compone...

Custom matchers can be added in jasmine using the syntax: jasmine.addMatchers([ toMatch: function () { return { compare: function (actual, expected) { return { pass: actual===expected, message: "Expected actual to match expected...

Protractor can selectively run groups of tests using fdescribe() instead of describe(). fdescribe('first group',()=>{ it('only this test will run',()=>{ //code that will run }); }); describe('second group',()=>{ it('this code will not run',()=>{ //code...

Protractor allows tests to be set as pending. This means that protractor will not execute the test, but will instead output: Pending: 1) Test Name Temporarily disabled with xit Or, if disabled with xdescribe(): Pending: 1) Test Name No reason given Combinations A xit() within an xdesc...

Old UI system tool, now used for fast and simple prototyping or debugging in game. void OnGUI () { GUILayout.Label ("I'm a simple label text displayed in game."); if ( GUILayout.Button("CLICK ME") ) { GUILayout.TextArea ("This is a \n ...

A TypeScript function can take in parameters of multiple, predefined types using union types. function whatTime(hour:number|string, minute:number|string):string{ return hour+':'+minute; } whatTime(1,30) //'1:30' whatTime('1',30) //'1:30' whatTime(1,'30') //'1:30' wha...

Custom matchers will have their pass value negated when using 'not'. Custom matchers can have a negative compare attribute to explicitly handle cases where their negation is desired: toMatch: function () { return { compare: function (actual, expected) { return...
