Windows servers use .pfx files which contain the public key file (SSL certificate file) and the private key file. However, this can also be converted to .pem files to be used on Linux server using OpenSSL.

There is already basic article on upgrading Drupal 8 to Drupal 9, however, there is a bit more to consider, with my current setup of Drupal using composer.

Prerequisite
- A Solr server running either on your local environment or on another server
Create a new Solr server
- Open your browser and login to your Drupal site
- Go to Configuration -> Search and metadata -> Search API
- Click the Add server button
- In the Add search server page, enter the following information
- Server name: Solr
- Backend: Solr
- Solr Connector: Standard
- Solr host: staging.upanupstudios.co

Apache "Solr is the popular, blazing-fast, open source enterprise search platform built on Apache Lucene™." it is "highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery, centralized configuration and more. Solr powers the search and navigation features of many of the world's largest internet sites."
You can easily install Solr on your MacOS using homebrew.

When making changes in your httpd-vhost.conf file, make sure to test it before reloading the apache config file or restarting apache.
Mac OSX
apachectl configtest
XAMPP OSX
/Applications/XAMPP/xamppfiles/bin/apachectl configtest
Errors should display, if there are any, otherwise you'll see the Syntax OK to indicate that there are no errors and you can reload the apache config file or restart apache.

I previously wrote how to Display copyright disclaimer on your webcam using CamTwist, and here's how to do the same using the Open Broadcaster Software (OBS).

Being part of leading team requires to motivate and inspire your colleagues in doing their work well. In our weekly meeting, I'll be tracking the quotes I've scoured the internet throughout the year.

- Open the terminal app (or the terminal in VS Code) and change to the root site directory of the site you are updating
cd [path/to/site/root/directory]
- Switch to the main branch and fetch the latest changes
git checkout master git fetch --all git pull
- Create a new branch from the main branch for the Drupal core update
git checkout -b update/core-[version]
- Upda

At times, there are differences between your local or staging and production environment in handling URL encodings. In strict environments (likely production), HTML links to files with encoded characters in their file name will result to a 403 (not found) error. Therefore, you must rename the file names in your directory.
Install rename utility
In MacOS, use homebrew to install the rename utility.

If you’re using multiple Webex accounts, you might get stuck signing-in to the same account even though you login into another when starting or joining a meeting using the Webex Meetings app. This certainly might get annoying but here is the work-around.
For MacOS (Catalina), what you have to do is clear your saved logins using the Keychain Access app.

Part of administering web servers is looking through log files for clues whenever you come across issues with your web server or web applications. The logs most often will tell you exactly what went wrong. However, log files can be separated into multiple files and compressed to save space.
To search for a particular text through these compressed files easily, use the following command:
find . -name "*.gz" | xargs -n 1 zgrep -H "[text to search]"

I finally figured out how to make Google Translate work with the Drupal 8 site! I kept getting a 403 forbidden message whenever I change the language. This is because of the Drupal security directive in place in the .htaccess file.
