For those of you who didn’t know, KeePassXC is a free open-source password manager or safe which helps you to manage your passwords in a secure way.

  While you are using the nano editor and copying text, it is saved in a buffer called the Cutbuffer, and it is not the same as the clipboard because Gnome maintains the clipboard.

It has a good set of features that make it above the others. But, how can you copy from the clipboard to the nano editor in Linux?

• Grafana Loki doesn't duplicate a central syslog server (or vice versa)

  We've had a central syslog server for a long time, and recently we've set up a Grafana Loki server as well, where we're sending pretty much a duplicate of the logs that go to the syslog server. After using Loki for a while, I've come to the conclusion that the two serve different purposes and neither makes the other unnecessary.

  (Grafana Loki is concisely called "Prometheus for logs", or to quote its website it's 'a log aggregation system designed to store and query logs from all your applications and infrastructure'. You can see how this might sound like it duplicates a central syslog server.)

• How to Install VidCutter on Linux Mint 21 LTS

  VidCutter is a free, open-source application that can be used to cut video and audio files. It has tools for cutting all sorts of media, but it’s not a full-blown video editor; instead, its focus lies solely on slicing up videos into clips you could then upload onto your website (or send someone).

  VidCutter has features that make it easy to get the exact clip you want. It supports many video and audio formats, so you’re not limited to just mp4 files. You can also use it to extract audio from a video file if you want the audio track. Once you’ve imported your media file, you can use the built-in player to preview it and mark out your clip’s start and end points using the easy-to-use interface. When you’re happy with your selection, hit the “cut” button, and VidCutter will do the rest. The output file can be saved in any format you like, so you’re not stuck with whatever format your source file is in. Whether you need to trim down a long video or extract a short clip for use elsewhere, VidCutter is the perfect tool for the job.

  In the following tutorial, you will learn how to install VidCutter on Linux Mint 21 LTS release series using two different methods, PPA or the alternative third-party Flatpak package manager.
