Copied the content for quick reference

Each YouTube video has four generated images. They are predictably formatted as follows:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg

https://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg

First, install Solaar to see the battery level on the taskbar

sudo apt-get install solaar

To remap the keys, install

sudo apt-get install xbindkeys xautomation

System Updates

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoremove
sudo apt-get autoclean

Converting mkv to mp4 with `ffmpeg`

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.

	Try using "rsync" with the "-n" option, which just does a "dry run" and tells you what it would do.

	-c will tell rsync to look at checksums, not just date & length – Mike Aug 5 '14 at 22:07

	--delete is needful. Without it, you won't see any files that are present on the 2nd machine but not on the 1st. Make sure you have the dry run -n option. – JellicleCat Mar 22 '15 at 15:12
