th elements are very commonly used to indicate headings for table rows and columns, like so: <table> <thead> <tr> <td></td> <th>Column Heading 1</th> <th>Column Heading 2</th> </tr...

Before making a pull request, it is useful to make sure that compile is successful and tests are passing for each commit in the branch. We can do that automatically using -x parameter. For example: git rebase -i -x make will perform the interactive rebase and stop after each commit to execute mak...

import tensorflow as tf dims, layers = 32, 2 # Creating the forward and backwards cells lstm_fw_cell = tf.nn.rnn_cell.BasicLSTMCell(dims, forget_bias=1.0) lstm_bw_cell = tf.nn.rnn_cell.BasicLSTMCell(dims, forget_bias=1.0) # Pass lstm_fw_cell / lstm_bw_cell directly to tf.nn.bidrectional_rnn ...

go run will run a program without creating an executable file. Mostly useful for development. run will only execute packages whose package name is main. To demonstrate, we will use a simple Hello World example main.go: package main import fmt func main() { fmt.Println("Hello, World...

go build will compile a program into an executable file. To demonstrate, we will use a simple Hello World example main.go: package main import fmt func main() { fmt.Println("Hello, World!") } Compile the program: go build main.go build creates an executable program...

go clean will clean up any temporary files created when invoking go build on a program. It will also clean files left over from Makefiles.

go fmt will format a program's source code in a neat, idiomatic way that is easy to read and understand. It is recommended that you use go fmt on any source before you submit it for public viewing or committing into a version control system, to make reading it easier. To format a file: go fmt main...

Let's take a sample class: public class Transaction { public string Category { get; set; } public DateTime Date { get; set; } public decimal Amount { get; set; } } Now, let us consider a list of transactions: var transactions = new List<Transaction> { new Transaction...

Most analysis customization is in the createComponents class, where the Tokenizer and TokenFilters are defined. CharFilters can be added in the initReader method. Analyzer analyzer = new Analyzer() { @Override protected Reader initReader(String fieldName, Reader reader) { retu...

TokenStream stream = myAnalyzer.tokenStream("myField", textToAnalyze); stream.addAttribute(CharTermAttribute.class); stream.reset(); while(stream.incrementToken()) { CharTermAttribute token = stream.getAttribute(CharTermAttribute.class); System.out.println(token.toString()); ...

int signed_integer = -1; // The right shift operation exhibits implementation-defined behavior: int result = signed_integer >> 1;

// Supposing SCHAR_MAX, the maximum value that can be represented by a signed char, is // 127, the behavior of this assignment is implementation-defined: signed char integer; integer = 128;

// The allocation functions have implementation-defined behavior when the requested size // of the allocation is zero. void *p = malloc(0);

UISplitViewController must be the rootViewController of your application. AppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. self.window = [[UIWindow alloc] i...

It is illegal to access a reference to an object that has gone out of scope or been otherwise destroyed. Such a reference is said to be dangling since it no longer refers to a valid object. #include <iostream> int& getX() { int x = 42; return x; } int main() { int& r...

Pair allows us to treat two objects as one object. Pairs can be easily constructed with the help of template function std::make_pair. Alternative way is to create pair and assign its elements (first and second) later. #include <iostream> #include <utility> int main() { std::p...

In pass by value of parameter passing to a method, actual parameter value is copied to formal parameter value. So actual parameter value will not change after returning from called function. @interface SwapClass : NSObject -(void) swap:(NSInteger)num1 andNum2:(NSInteger)num2; @end @impleme...

In pass by reference of parameter passing to a method, address of actual parameter is passed to formal parameter. So actual parameter value will be changed after returning from called function. @interface SwapClass : NSObject -(void) swap:(int)num1 andNum2:(int)num2; @end @implementation S...
