5 min readTo forward a port on a running Vagrant box, you need to modify the Vagrantfile configuration file for the specific box you are working with. Inside the Vagrantfile, you can add a line of code that specifies the port forwarding configuration. This line typically looks like config.vm.network "forwarded_port", guest: 80, host: 8080, auto_correct: true. In this example, we are forwarding port 80 from the guest machine to port 8080 on the host machine.

In your Groovy script, you can use this method to wait for a specific condition to be true before starting the next parallel job. This can help in coordinating the execution of parallel jobs and prevent them from running simultaneously.

4 min readIn Elixir, you can write your own stream functions by defining modules that implement the Enumerable protocol. By doing so, you can create custom streams that generate or manipulate data as needed. To create a stream, use the Stream module and the Enum module in Elixir. You can define a custom stream function by implementing the Stream.run/2 function, which takes an initial value and a function that generates the next value in the stream.

4 min readAliases in Vagrant can be used to create shorter, more convenient commands for commonly used Vagrant operations. To use aliases in Vagrant, you can define them in your Vagrantfile using the config.aliases method. This allows you to create custom aliases for any Vagrant command or group of commands. Aliases can be as simple as a single command or a more complex sequence of commands.

2 min readIn Elixir, you can return a list by using the square brackets [ ]. Simply enclose the elements you want in the list inside the square brackets and return it. For example, you can define and return a list of numbers like [1, 2, 3, 4, 5]. Lists are one of the basic data structures in Elixir and are commonly used to store multiple elements of the same type.[rating:4418d73d-f96d-4383-97bd-2aa68e7b6810]How do you check if a value is in a list in Elixir?You can use the Enum.member.

5 min readTo add arguments to the body of a GET request in Groovy, you can use the uri property of the HTTPBuilder object and append the arguments to the end of the URL. For example, if you want to add two arguments foo and bar, you can do so by constructing the URI like this: http://example.com/api/resource?foo=value1&bar=value2. This way, the arguments will be included in the body of the GET request.

5 min readTo change the php.ini settings in your Vagrant virtual machine, you need to locate the php.ini file within the virtual machine's filesystem. This file is typically located in the /etc/php/ directory.Once you have located the php.ini file, you can open it in a text editor and make the necessary changes to the PHP configuration settings. You can adjust settings such as memory_limit, max_execution_time, and error_reporting to suit your needs.After making the desired changes, save the php.

3 min readIn Elixir, you can get the name of a struct using the __struct__ field. This field is automatically added to any struct created using the defstruct macro and contains the name of the struct as an atom. To access the name of a struct, you can simply access the __struct__ field of the struct instance. For example: defmodule Person do defstruct name: nil, age: nil end person = %Person{name: "Alice", age: 30} struct_name = person.__struct__ IO.
