    Firefox History and Bookmark Command Line Interface

These scripts use fzf and sqlite to efficiently query your firefox history and bookmarks.
This is heavily inspired by a post from the creator of fzf: https://junegunn.kr/2015/04/browsing-chrome-history-with-fzf/.
fzf allows you to select multiple items and the results returned will be the URLs.

    How to use Amazon S3 for storing your koel media files

In this short tutorial I will show you a (kind of hacky, but working) option to set up your koel instance so that you can store your media files on S3 as provided by Amazon.
I will also share some of the insights and experiences I had with the setup. Be aware that it's not officially supported and it might work differently to from what you expect. I myself have not had the setup running for a very long time yet.
Feel free to share your thoughts in the comments below or add to the document.
If you feel like supporting me, maybe use my Digital Ocean referral link when signing up. If you do that, please also support the original authors of the various tools. They did the hard work, I just glued it together.
Basic setup
