Liferay exposes many default and custom services available to other systems via JSON. To explore services on a particular liferay instance, use a given URL - A local instance in this case: http://localhost:8080/api/jsonws/ Select the required service, consume the service with the given syntax ...

To create \DateTimeImmutable in PHP 5.6+ use: \DateTimeImmutable::createFromMutable($concrete); Prior PHP 5.6 you can use: \DateTimeImmutable::createFromFormat(\DateTime::ISO8601, $mutable->format(\DateTime::ISO8601), $mutable->getTimezone());

var JSONObject = { stringProp: 'stringProp', booleanProp: false, intProp: 8 } var JSONString = JSON.stringify(JSONObject, ['intProp']); console.log(JSONString); /* output * {"intProp":8} */

var JSONObject = { stringProp: 'stringProp', booleanProp: false, intProp: 8 } var JSONString = JSON.stringify(JSONObject, null, 2); console.log(JSONString); /* output: * { * "stringProp": "stringProp", * "booleanProp": false, * "...

Despite you can write a binary number in C++14 like: int number =0b0001'0101; // ==21 here comes a famous example with a self-made implementation for binary numbers: Note: The whole template expanding program is running at compile time. template< char FIRST, char... REST > struct binary {...

Workflows can be somewhat limited in their functionality; for example, workflows cannot interact with line items. The Workflow Action script type is intended to be invoked by a Workflow to add scripting functionality to accomplish what the workflow itself cannot. Workflow Actions have a single onAc...

This is a step by step guide to set up the automated build process using Jenkins CI for your Android projects. The following steps assume that you have new hardware with just any flavor of Linux installed. It is also taken into account that you might have a remote machine. PART I: Initial setup on ...

PHP lacks a build-in function to encrypt and decrypt large files. openssl_encrypt can be used to encrypt strings, but loading a huge file into memory is a bad idea. So we have to write a userland function doing that. This example uses the symmetric AES-128-CBC algorithm to encrypt smaller chunks of...

Suppose you have two views ViewA and ViewB Instance of ViewB is created inside ViewA, so ViewA can send message to ViewB's instance, but for the reverse to happen we need to implement delegation (so that using delegate ViewB's instance could send message to ViewA) Follow these steps to implement t...

In order to get the total number of commits that each developer or contributor has made on a repository, you can simply use the git shortlog: git shortlog -s which provides the author names and number of commits by each one. Additionally, if you want to have the results calculated on all branch...

"Fat Model, Skinny Controller" is a very good first step, but it doesn't scale well once your codebase starts to grow. Let's think on the Single Responsibility of models. What is the single responsibility of models? Is it to hold business logic? Is it to hold non-response-related logic? ...

std::vector<int> primes = {2, 3, 5, 7, 11, 13}; for(auto prime : primes) { std::cout << prime << std::endl; }

In Vim, your configuration file is ~/.vimrc, with further configuration files in ~/.vim. In Neovim, configuration files are located in ~/.config/nvim. There is also no ~/.nvimrc file. Instead, use ~/.config/nvim/init.vim. You can import your Vim configuration directly into Neovim using this Unix c...

Javascript timestamps are based on the venerable UNIX time_t data type, and show the number of milliseconds since 1970-01-01 00:00:00 UTC. This expression gets the current time as a Javascript timestamp integer. (It does so correctly regardless of the current time_zone setting.) ROUND(UNIX_TIMEST...

We can use the get_bloginfo function to retrieve the email address of the site administrator. <?php echo get_bloginfo('admin_email'); ?>

For a non-main packages as well as main, instead of adding flags inside the code, write benchmarks in the test package , for example: func BenchmarkHello(b *testing.B) { for i := 0; i < b.N; i++ { fmt.Sprintf("hello") } } Then run the test with the profile flag ...

once a prof file has been generated, one can access the prof file using go tools: go tool pprof cpu.prof This will enter into a command line interface for exploring the profile Common commands include: (pprof) top lists top processes in memory (pprof) peek Lists all processes, use reg...
