In build.sbt, make sure you include (here for Mysql and PostGreSQL): "mysql" % "mysql-connector-java" % "5.1.20", "org.postgresql" % "postgresql" % "9.3-1100-jdbc4", "com.typesafe.slick" %% "slick" % "3.1.1&...

First, you have to request authorization of location services let locationManager = CLLocationManager() locationManager.delegate = self locationManager.requestWhenInUseAuthorization() // OR locationManager.requestAlwaysAuthorization() Then you can get all iBeacons' information inside didRange...

Sometimes you may want to perform some additional actions to Auto Layout calculations done by UIKit itself. Example: when you have a UIView that has a maskLayer, you may need to update maskLayer as soon as Auto Layout changes UIView's frame // CustomView.m - (void)layoutSubviews { [super la...

To validate arguments to methods called on a mock, use the ArgumentCaptor class. This will allow you to extract the arguments into your test method and perform assertions on them. This example tests a method which updates the name of a user with a given ID. The method loads the user, updates the na...

NSURL *url = [NSURL URLWithString:@"http://www.example.com/images/apple-tree.jpg"]; NSString *fileName = [url lastPathComponent]; // fileName = "apple-tree.jpg"

Given a DataFrame: s1 = pd.Series([1,2,3]) s2 = pd.Series(['a','b','c']) df = pd.DataFrame([list(s1), list(s2)], columns = ["C1", "C2", "C3"]) print df Output: C1 C2 C3 0 1 2 3 1 a b c Lets add a new row, [10,11,12]: df = pd.DataFrame(np.array(...

Using the same example as Evaluating a NodeList in an XML document, here is how you would make multiple XPath calls efficiently: Given the following XML document: <documentation> <tags> <tag name="Java"> <topic name="Regular expression...

In this case, you want to have the expression compiled before the evaluations, so that each call to evaluate does not compile the same expression. The simple syntax would be: XPath xPath = XPathFactory.newInstance().newXPath(); //Make new XPath XPathExpression exp = xPath.compile("/documentat...

Shortcode is a small piece of code that can be added into the WordPress editor and will output something different once the page is published or previewed. Frequently, shortcodes are added to the theme functions.php file, but that's not a good practice as shortcodes are expected to keep working aft...

When programming in Prolog, we must pick two kinds of names: names of predicates names of variables. A good predicate name makes clear what each argument means. By convention, underscores are used in names to separate the description of different arguments. This is because underscores_keep_ev...

Ideally, Prolog predicates can be used in all directions. For many pure predicates, this is also actually the case. However, some predicates only work in particular modes, which means instantiation patterns of their arguments. By convention, the most common argument order for such predicates is: ...

.git/hooks/pre-commit #!/bin/sh if [ -s pom.xml ]; then echo "Running mvn verify" mvn clean verify if [ $? -ne 0 ]; then echo "Maven build failed" exit 1 fi fi

Prior to C++17, when writing a template non-type parameter, you had to specify its type first. So a common pattern became writing something like: template <class T, T N> struct integral_constant { using type = T; static constexpr T value = N; }; using five = integral_constant&l...

Types used in Sets and Dictionaries(key) must conform to Hashable protocol which inherits from Equatable protocol. Custom type conforming to Hashable protocol must implement A calculated property hashValue Define one of the equality operators i.e. == or !=. Following example implements Hasha...

Create a basic application with single view application template with swift as language Add SWRevealViewController.h and SWRevealViewController.m then click on Create Bridging Header button and add #import "SWRevealViewController.h" on the Bridging header Then select viewControll...

LINQ provides a method that makes it easy to create a collection filled with sequential numbers. For example, you can declare an array which contains the integers between 1 and 100. The Enumerable.Range method allows us to create sequence of integer numbers from a specified start position and a num...
