Who hasn’t found himself in a situation where you have to make changes to multiple images and you get fed up with doing the job one image at a time? Well today I had to combine 13 images into a single pdf and it came out way to large to be useful.
Continue readingUpgrade Debian based system
We want to upgrade Linux Mint 18.2 to version 20, and we don’t want to go through 3 upgrades to get it done. Instead we will make a proper inventory of the current system, back up all the stuff we want to keep and install Mint 20 from scratch. This approach should work fine for all Debian based systems.
If you want the possibility to get back to your previous system, make sure to make a full backup and keep it safe somewhere, but in most cases it’s best to move to current affairs and deal with possible trouble by fixing the issues in the new system.

There are no installation images for sid, but we can choose either stable or a daily built (testing). If you are absolutely certain that you will have connection to the internet while installing, i.e. in VirtualBox, with a cable or with the correct firmware available for wifi, you should use the netinstall image, otherwise a cd image that will give you the base system that will allow you to work and get online.

I’ve been working in Mint for the past years, but I somehow feel I should be running Debian. So after trying it in a Virtualbox for a while, I have decided to go ahead. It takes a thorough preparation though: I need to make sure not to loose anything or any any functionality. Apart from all the usual applications I need:

I’ve always preferred not to have my data files on the same partition as my system files and often I have used a separate /home partition for this. This has a huge downside though. As your home folder is also used by the system to hold non global setting files, you risk making a mess of settings when you have different system installations sharing the same /home partition.
The solution I found best is to have symbolic links in the /home folder (that resides in the system root; no separate /home partition).

When you make your recording, leave some seconds for noise reduction and create a starting point by clapping your hands. This will show as a peak in Audacity. I usually record in wav at 44.1 kHz sample rate and 24 bit sample format. Try and stay around -12dB and avoid peaks of over -6dB (at over 0dB you only record noise). If you expect huge volume changes, stay around -20dB or even lower.
