Can Foam store the data in files in a local folder using a file sharing tool like Dropbox, SyncThing or Resilien?
I don't want private notes going on Github.
I agree that git is a nightmare with a user-hostile interface. Keep backups outside of git and just bite the bullet and learn it. There is no middle-ground, you are either floundering in a storm or master of git but it's everywhere so you have to get through the learning curve. If you are using the command line I recommend 'easygit' (eg) (https://people.gnome.org/~newren/eg/) or 'gitless' (gl) as far saner interfaces that don't hide git from you but make the interface simpler and more consistent.
You shouldn't write an article telling people not to use Python if you don't really understand Python in the first place. Lists are called Lists in Python because they are just that: lists of varying and dynamic length of heterogeneous datatypes. If you want an array with a homogeneous datatype packed efficiently sequentially in memory Python also has that: a=array('i').
Unless I'm behind the news, I think the incident people are referring to is: Triplebyte added a new feature to have a public profile highlighting your skills for your job-hunt. They didn't think it through and made the new profile public by default. Many people who were job-hunting discretely were understandably upset by this.
I tried it years ago. I had a good configuration, and then something broke, and I got frustrated. I find Vim/Neovim a lot more compact and I have been getting by with very few plugins just fine. I also like that I can hop on any system, and a plain Vim is easier for me to dive into than a plain emacs.
