It scales nicely from just a single server to thousands of servers, even in complex multi/mixed/hybrid cloud environments, and given enough disk space it can keep your metrics for years.

LosslessCut

The Swiss Army Knife of Lossless Video/Audio Editing.

LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc.

It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode.

Open source alternative to tools like DavinciResolve [ByteCrawl/123]

KeePass 2

A free open source password manager, which helps you to manage your passwords in a secure way. You can store all your passwords in one database, which is locked with a master key. So you only have to remember one single master key to unlock the whole database. Database files are encrypted using the best and most secure encryption algorithms currently known (AES-256, ChaCha20 and Twofish).

I personally use KeePass 2 with the KeePass2Android app and the StrongBox iOS app and I synchronize my database via OneDrive. For sure not the most beautiful looking solution but it's very secure and my database file can't get stolen if the password manager's website gets hacked.
