This function allows you to specify the size of the sliding window and a step parameter to control how many items to move on each iteration. By utilizing the windowed function, you can easily access the current item and the next item in the collection within the loop body.

5 min readTo write a generic type serializer in Kotlin, you can start by creating a generic class that takes the type of object you want to serialize as a parameter. Within this class, you can define a function that will handle the serialization logic for objects of that type.You can use reflection to access the properties of the object and serialize them into a suitable format, such as JSON or XML.

3 min readTo create a .htaccess file for PHP, you can use a text editor such as Notepad or TextEdit. Start by opening the text editor and creating a new file. Save the file as ".htaccess" (make sure the file extension is .htaccess and not .txt).You can then add various configurations to the .htaccess file to customize the behavior of your PHP scripts. For example, you can set up redirections, protect directories with a password, enable server-side caching, and more.Remember to test your .

4 min readTo access data inside a map in Elixir, you can use the dot notation or the square bracket notation.Using the dot notation, you can access the value of a key in a map by specifying the key directly after the map variable followed by a dot. For example, if you have a map variable called my_map and you want to access the value of the key :name, you can do so by typing my_map.name.Alternatively, you can also use the square bracket notation to access data inside a map.

6 min readIn Kotlin, you can transform a Flow<T> to a StateFlow<List<T>> by collecting the items emitted by the Flow into a List and then updating a StateFlow with this List whenever a new item is emitted. This can be achieved using the stateIn operator provided by the Kotlin Flow library.First, create a StateFlow of type List<T> by using the stateIn operator with an initial empty list as the initial value.

4 min readTo rewrite part of a URL in .htaccess, you can use the RewriteRule directive. This directive allows you to define rules to rewrite URLs based on certain patterns. For example, if you want to rewrite all URLs that contain the string "old" to have the string "new" instead, you can use the following code in your .htaccess file: RewriteEngine On RewriteRule ^(.*)old(.

6 min readTo connect to a MongoDB replica cluster in Elixir, you can use the official Elixir MongoDB driver called "mongodb_ecto". First, add the driver to your mix.exs file as a dependency. Then, configure your MongoDB connection settings in your application configuration file. Use the MongoDB URI that includes the replica set name in the connection string. Finally, create a connection to the replica set using the MongoDB.Ecto connection module and pass in the connection details.

3 min readIn Kotlin, "by" is used as a keyword to delegate a property or a method call to another object. This allows you to inherit behavior from the delegate object without explicitly defining all the methods or properties in the current class.On the other hand, "=" is used to assign a value to a variable or a property. It is used to store a value in a specific location in memory.In summary, "by" is used for delegation, while "=" is used for assignment.

3 min readTo match every character except a slash in .htaccess, you can use the following regex pattern:([^/]+)This pattern will match one or more of any character that is not a slash. It can be used in .htaccess files for rewriting URLs or other server-side configurations. Just be sure to test your regex thoroughly to ensure it is behaving as expected before deploying it in a live environment.[rating:233766ea-dc8c-4894-8eb7-12a445728045]What is the significance of the dollar sign in regular expressions.
