Foreword: few people has this sort of ability described below: Pretend you've never seen your code; pretend you don't know anything about your code and/or the business domain and/or assumptions your code supposes. Then go thru your code and try to figure out if you can understand it given your previous knowledge about it (i.e.: zero knowledgge).

I had bad experiences with Ubuntu in 2004, moved to Debian and I'm happy ever since. Debian in past was lacking several things but at the moment it is pretty polished and functional from end-users' perspective. For better and faster results (I'm impatient!) I suggest installing Debian from a special build which contain additional [non-free] firmware and drivers. It will recognize your wireless card and eventually other uncommon pieces of hardware you may have. https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/9.3.0+nonfree/amd64/iso-dvd/firmware-9.3.0-amd64-DVD-1.iso You may also be interested in my post installation scripts. In particular, I'm consolidating all useful stuff into a single script, which is meant to be executed first thing after you install Debian: https://github.com/frgomes/debian-scripts/blob/master/install-000-postinstall.sh Other useful stuff you may or may not be interested: http://github.com/frgomes/debian-bin I hope it helps.
