4 min readTo print the callstack in Kotlin, you can use the Thread.currentThread().stackTrace property to access the current callstack as an array of StackTraceElement objects. You can then loop through and print each element to display the callstack information. Here is an example code snippet that demonstrates how to print the callstack in Kotlin: fun printCallStack() { val stackTrace = Thread.currentThread().stackTrace stackTrace.forEach { println(it.className + "." + it.

4 min readTo ignore the .htaccess file on a subdomain, you can create a separate configuration file specifically for that subdomain. This file should be named subdomain.conf and placed in the same directory as the main domain's .htaccess file. In this subdomain.conf file, you can specify the configurations and directives you want to apply only to the subdomain, without affecting the main domain's settings. Once you have created and saved the subdomain.

3 min readTo sort a list in a custom order in Kotlin, you can create a custom Comparator that defines the order in which elements should be sorted. You can then use the sortedWith() function on the list, passing in your custom Comparator to sort the list according to the custom order specified. This allows you to sort the list based on your own criteria rather than the default sorting order.[rating:5c241908-e13b-494b-ac73-26ced6913ab0]How to customize the order of sorting in Kotlin.

3 min readTo redirect a specific URL using .htaccess, you can use the Redirect directive followed by the URL you want to redirect from and the URL you want to redirect to. For example, to redirect "example.com/oldpage" to "example.com/newpage", you can add the following line to your .htaccess file:Redirect /oldpage http://example.com/newpageMake sure to save the changes to the .htaccess file and the redirect should now be in effect. This will redirect any requests for "example.

4 min readTo implement a sub-request in .htaccess, you can use the Apache's mod_rewrite module. This module allows you to rewrite URLs based on certain conditions and rules defined in the .htaccess file.To implement a sub-request, you can create a RewriteRule in the .htaccess file that specifies the sub-request URL and the destination URL that the sub-request should go to. This can be done by using the RewriteRule directive along with the PT flag, which stands for "pass-through".

6 min readIn Kotlin, you can generate a flow based on another flow by using transformation functions such as map, filter, and flatMap. These functions allow you to transform the elements emitted by the original flow into a new flow with modified or filtered elements.For example, you can use the map function to apply a transformation to each element emitted by the original flow and create a new flow with the transformed elements.

4 min readTo hide a directory in .htaccess, you can use the "Options -Indexes" directive in your .htaccess file. This will prevent browsers from being able to access the contents of that directory directly. Additionally, you can also create a blank index.html file inside the directory you want to hide, which will prevent the directory listing from being displayed in case the server does not support the "Options -Indexes" directive.

6 min readIn Kotlin, you can wait for an async operation to complete using coroutines. You can use the runBlocking function, which blocks the current thread until the coroutine inside it completes. Another option is to use the await function, which waits for the result of the async operation. You can also use the async function to start a coroutine that will run concurrently with other coroutines, and then use await to wait for its result.

5 min readTo disable the use of .htaccess in subdirectories, you can use the "AllowOverride None" directive in the parent directory's configuration file. This directive will prevent any .htaccess files in subdirectories from being processed by the server. Alternatively, you can also set specific directives in the main configuration file to override any settings in the .htaccess files. Keep in mind that disabling .

4 min readIn Kotlin, you can use the runBlocking coroutine builder to wait for a task to finish. This allows you to block the current thread until the specified task is completed. Additionally, you can use the await function on deferred values to also wait for the result of a coroutine. By using coroutines in Kotlin, you can efficiently manage asynchronous tasks and easily wait for them to finish before proceeding with the rest of your code.

3 min readTo remove a specific string from a URL using the .htaccess file, you can use a rewrite rule. You can use the RewriteRule directive along with the RewriteCond directive to match the specific string and redirect the URL without that string. You can also use regular expressions to match the string more precisely. Remember to test the rewrite rule thoroughly before implementing it on your live website to ensure it doesn't cause any unexpected issues.

4 min readTo disable WordPress .htaccess catch-all, you can do so by accessing your website's root directory via FTP or file manager in cPanel. Look for the .htaccess file in the root directory and open it using a text editor.Once the file is open, locate the section of code related to the catch-all redirect, which typically looks like: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} .
