Different platforms can have separate implementations of the same method. This example also illustrates how build tags and file suffixes can be used together. File main.go: package main import "fmt" func main() { fmt.Println("Hello World from Conditional Compilation Doc!&...

@Mojo(name = "hi", defaultPhase = LifecyclePhase.COMPILE)

A synchronous producer-consumer solution ensures that the consumer reads every data item written by the producer exactly one time. Asynchronous solutions allow the consumer to sample the output of the producer. Either the consumer consumes the data faster than it is produced, or the consumer consume...

This example uses the main procedure as the producer task. In Ada the main procedure always runs in a task separate from all other tasks in the program, see minimal example. ------------------------------------------------------------------ -- Sampling Consumer -- --------------------------------...

4.1 This code loads, compiles, and links a single file that creates a separate shader program for a single stage. If there are errors, it will get the info-log for those errors. The code uses some commonly-available C++11 functionality. #include <string> #include <fstream> //In C+...

private final String COLLECTION_NAME = "myCollection"; private final String ZOOKEPER_CLIENT_TIMEOUT_MS = "1000000" private Map<String, String> getShardLeaders(CloudSolrServer cloudSolrServer) throws InterruptedException, KeeperException { Map<String, Stri...

The Assets folder is the most common place to store your GLSL-ES shader files. To use them in your OpenGL ES application you need to load them to a string in the first place. This functions creates a string from the asset file: private String loadStringFromAssetFile(Context myContext, String filePa...

Character literals provide the most convenient way to express char values in Java source code. A character literal consists of: An opening single-quote (') character. A representation of a character. This representation cannot be a single-quote or a line-break character, but it can be an escap...

This example shows multiple producers and consumers sharing the same buffer. Protected entries in Ada implement a queue to handle waiting tasks. The default queuing policy is First In First Out. ------------------------------------------------------------------ -- Multiple producers and consumers ...

Atom is a hackable text editor created by GitHub and developed on top of the Electron desktop application platform. This means it can be used as a text editor for basic programming up to a full-sized IDE. It is also extremely customisable, it provides thousands of community-made packages (syntax hi...

The traditional GLSL compilation model involves compiling code for a shader stage into a shader object, then linking multiple shader objects (covering all of the stages you want to use) into a single program object. Since 4.2, program objects can be created that have only one shader stage. This met...

Pushd "D:\Foo" Dir Popd Pushd will change the directory to the directory following (in this case D:\Foo. Popd returns back to the original directory.

Naturally, being able to install hard drive cloning utilities can be an important aspect of installing and maintaining your operating system. Getting set up with Clonezilla is surprisingly less straightforward than I'd have expected. The wealth of options, while valuable, also makes each part of id...

Let's take this example without using generics protocol JSONDecodable { static func from(_ json: [String: Any]) -> Any? } The protocol declaration seems fine unless you actually use it. let myTestObject = TestObject.from(myJson) as? TestObject Why do you have to cast the result to T...

@Configuration public class AppSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired DataSource dataSource; @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth.jdbcAuthentication().dataSource(dataSource) .pa...

Selenium-Grid is a configuration of Hub & Node which allows you to run your tests on different machines against different browser combinations in parallel. That is, running multiple tests at the same time against different machines running different browsers on different operating systems. In ot...

The Hub The Hub is the main engine/central point of the entire configuration, point where all the nodes are connected. Hub should run only on a single machine. There should only be 1 hub running where all the tests are loaded. Tests will be run on the machines where hub is running, but you can...

Locking on an stack-allocated / local variable One of the fallacies while using lock is the usage of local objects as locker in a function. Since these local object instances will differ on each call of the function, lock will not perform as expected. List<string> stringList = new List<st...

TypeScript supports interfaces, but the compiler outputs JavaScript, which doesn't. Therefore, interfaces are effectively lost in the compile step. This is why type checking on interfaces relies on the shape of the object - meaning whether the object supports the fields and functions on the interfac...

For Getting updated or to do something before app goes live to user you can use below method. AppDidFinishLaunching - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Write your code before app launch return YES; } While ...
