The simplest and cleanest way to add an external configuration is through a separate Gradle file build.gradle apply from: './keystore.gradle' android{ signingConfigs { release { storeFile file(keystore.storeFile) storePassword keystore.storePassword ...

Using more than one theme in your Android application, you can add custom colors to every theme, to be like this: First, we have to add our themes to style.xml like this: <style name="OneTheme" parent="Theme.AppCompat.Light.DarkActionBar"> </style> <!--...

18.0 By default, any function specified in a -callback directive in a behaviour module must be exported by a module that implements that behaviour. Otherwise, you'll get a compiler warning. Sometimes, you want a callback function to be optional: the behaviour would use it if present and exported,...

Suppose that we have a text and a pattern. We need to determine if the pattern exists in the text or not. For example: +-------+---+---+---+---+---+---+---+---+ | Index | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | +-------+---+---+---+---+---+---+---+---+ | Text | a | b | c | b | c | g | l | x | +-------...

To sort this table Employee by department, you would use ORDER BY Department. However, if you want a different sort order that is not alphabetical, you have to map the Department values into different values that sort correctly; this can be done with a CASE expression: NameDepartmentHasanITYusufHR...

Entity falling distance is the distance the entity have fallen without reaching a block. It can be used to calculate different damage from falling, or activating an effect after a big fall. Retrieving the falling distance float distanceFell = entity.getFallingDistance(); Setting the falling ...

If you find that no matter what you put in your URL only your default page is loading, it might be that your server does not support the PATH_INFO variable needed to serve search-engine friendly URLs. As a first step, open your application/config/config.php file and look for the URI Protocol inform...

Before Java 8, there was DateFormat and SimpleDateFormat classes in the package java.text and this legacy code will be continued to be used for sometime. But, Java 8 offers a modern approach to handling Formatting and Parsing. In formatting and parsing first you pass a String object to DateTimeFor...

Packages are collections of R functions, data, and compiled code in a well-defined format. Public (and private) repositories are used to host collections of R packages. The largest collection of R packages is available from CRAN. Some of the most popular R machine learning packages are the following...

from sklearn import svm X = [[1, 2], [3, 4]] #Training Samples y = [1, 2] #Class labels model = svm.SVC() #Making a support vector classifier model model.fit(X, y) #Fitting the data clf.predict([[2, 3]]) #After fitting, new data can be classified by using predict()

These three map functions are equivalent, so use the variation that your team finds most readable. val numberNames = Map(1 -> "One", 2 -> "Two", 3 -> "Three") // 1. No extraction numberNames.map(it => s"${it._1} is written ${it._2}" ) // 2....

Suppose we have an array: +-------+-----+-----+-----+-----+-----+-----+ | Index | 0 | 1 | 2 | 3 | 4 | 5 | +-------+-----+-----+-----+-----+-----+-----+ | Value | -1 | 3 | 4 | 0 | 2 | 1 | +-------+-----+-----+-----+-----+-----+-----+ We want to perform some query on thi...

Let's say, we have an array: Item = {-1, 0, 3, 6}. We want to construct SegmentTree array to find out the minimum value in a given range. Our segment tree will look like: The numbers below the nodes show the indices of each values that we'll store in our SegmentTree array. We can see that, to sto...

Import libraries (language dependency: python 2.7) import tensorflow as tf import numpy as np from sklearn.datasets import fetch_mldata from sklearn.model_selection import train_test_split load data, prepare data mnist = fetch_mldata('MNIST original', data_home='./') print "MNIST data,...

Collection Operators can be used in a KVC key path to perform an operation on a “collection-type” property (i.e. NSArray, NSSet and similar). For example, a common operation to perform is to count the objects in a collection. To achieve this, you use the @count collection operator: self.array = @[@...

In C++, code must be declared or defined before usage. For example, the following produces a compile time error: int main() { foo(2); // error: foo is called, but has not yet been declared } void foo(int x) // this later definition is not known in main { } There are two ways to resolve...

The following Codes can be found from Weka course Given iris.arff is loaded in weka, inside Weka Explorer's R console or Weka KnowledgeFlow's R Scripting, you can play with the following codes to make beautiful plots: library(ggplot2) ggplot(rdata, aes(x = petallength)) + geom_density() ...

Implement ICloneable in a class with a twist. Expose a public type safe Clone() and implement object Clone() privately. public class Person : ICloneable { // Contents of class public string Name { get; set; } public int Age { get; set; } // Constructor public Person(string...

The implementation of ICloneable for a struct is not generally needed because structs do a memberwise copy with the assignment operator =. But the design might require the implementation of another interface that inherits from ICloneable. Another reason would be if the struct contains a reference t...
