My daily driver is a 10yo Dell business laptop. Before that I ran a similarly aged Lenovo. I run mint.
In my experience, the amount of ram and an SSD are the biggest contributors to how good the performance feels. Running mint on 4G is possible, but performance is comprised. 8G is perfectly fine most of the time. 16G (my current setup) is peachy keen. I’m astounded what I can do in blender on a 10yo machine.
That said, if you can afford one (and they operate in your country - they don’t here), then grab a framework, like others have said. If that’s not an option, then add some ram and an SSD.
My 2c.
That maxim is no longer true, especially in the medium-to-long term. Reddit posts older than 8 or so years old aren’t accessible (even to their creators), same with the original Digg posts. If you go back to the Usenet days, most posts haven’t been archived and are lost, especially those from the smaller newsgroups. I expect over the coming decades, we’ll see data loss as a growing issue.
