First, you need to open your SQLite database, which can be done as follows: SQLiteDatabase myDataBase; String mPath = dbhelper.DATABASE_PATH + dbhelper.DATABASE_NAME; myDataBase = SQLiteDatabase.openDatabase(mPath, null, SQLiteDatabase.OPEN_READWRITE); After opening the database, you can easi...

Kotlin objects are actually just singletons. Its primary advantage is that you don't have to use SomeSingleton.INSTANCE to get the instance of the singleton. In java your singleton looks like this: public enum SharedRegistry { INSTANCE; public void register(String key, Object thing) {} ...

// sample token string taken from the New example tokenString := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJuYmYiOjE0NDQ0Nzg0MDB9.u1riaD1rW97opCoAuRCTy4w58Br-Zk-bh7vLiRIsrpU" // Parse takes the token string and a function for looking up the key. The latter is especially ...

The StandardClaim is embedded in the custom type to allow for easy encoding, parsing and validation of standard claims. tokenString := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c" type MyCustomCla...

// Create a new token object, specifying signing method and the claims // you would like it to contain. token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{ "foo": "bar", "nbf": time.Date(2015, 10, 10, 12, 0, 0, 0, time.UTC).Unix(), }) // Si...

The StandardClaims type is designed to be embedded into your custom types to provide standard validation features. You can use it alone, but there's no way to retrieve other fields after parsing. See the custom claims example for intended usage. mySigningKey := []byte("AllYourBase") //...

// Token from another example. This token is expired var tokenString = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c" token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error...

Atom is versatile and flexible text editor and has hundreds of community-made, open-source packages that can compile and run source files, for many languages. This guide will show how easy it is to code Python with the Atom editor. This guide assumes you do not have Python nor Atom installed in you...

Nokogiri is somewhat like a browser, in that it will attempt to provide something useful even if the incoming HTML or XML is malformed. Unfortunately it usually does it silently, but we can ask for a list of the errors using errors: require 'nokogiri' doc = Nokogiri::XML('<node><foo/&gt...

Each fundamental opencl type has a vector version. You can use the vector type by appending the number of desired components after the type. Supported number of components are 2,3,4,8 and 16. OpenCL 1.0 does not offer three components. You can initialize any vector using two ways: Provide a sing...

Recent versions of Delphi ships with the TStopwatch record which is for time interval measurement. Example usage: uses System.Diagnostics; var StopWatch: TStopwatch; ElapsedMillseconds: Int64; begin StopWatch := TStopwatch.StartNew; // do something that requires measurement El...

To use Processing in Eclipse, start by creating a new Java project. Then, select File > Import and then choose General > File System to locate the core.jar file. It can be found in PATH_TO_PROCESSING/core/library/ for Windows or /Applications/Processing 3.app/Contents/Java/core/library/ for Ma...

If you have: val r = Random(233) infix inline operator fun Int.rem(block: () -> Unit) { if (r.nextInt(100) < this) block() } You can write the following DSL-like code: 20 % { println("The possibility you see this message is 20%") }

In this example, a sine curve and a cosine curve are plotted in the same figure by superimposing the plots on top of each other. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sharing similar x, y limits # Using single plot command and legend import...

Similar to the previous example, here, a sine and a cosine curve are plotted on the same figure using separate plot commands. This is more Pythonic and can be used to get separate handles for each plot. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sha...

There are two methods using which you can consume data from AWS S3 bucket. Using sc.textFile (or sc.wholeTextFiles) API: This api can be used for HDFS and local file system as well. aws_config = {} # set your aws credential here sc._jsc.hadoopConfiguration().set("fs.s3n.awsSecretAccessK...

Seismic is an Android device shake detection library by Square. To use it just start listening to the shake events emitted by it. @Override protected void onCreate(Bundle savedInstanceState) { sm = (SensorManager) getSystemService(SENSOR_SERVICE); sd = new ShakeDetector(() -> { /* rea...

This section explains how the tokenized input from Part 1 is processed - it is done using Context Free Grammars (CFGs). The grammar must be specified, and the tokens are processed according to the grammar. Under the hood, the parser uses an LALR parser. # Yacc example import ply.yacc as yacc ...

We now need to access to our declared resources, in order to do that from XAML code we use {ThemeResource ResourceKey} or {StaticResource ResourceKey} to be continued later.
