Different distros are better for different things. For example, some require give you more control over the OS but are more difficult to learn, or require learning more things at once. Others will be easier to try out but may make choices on your behalf that you don’t like - or distribute software in ways you don’t like.
Linux from Scratch will have a fairly steep learning curve. Nothing wrong with that, but you’d want to prepare yourself to be cool with things breaking or not making sense for a while.
Puppy Linux is minimalist, which is something people usually only want after they’ve tried out something else that’s not minimalist. I would recommend trying out something more general-purpose and try out different desktop environments and applications first.
Alcohol refers to an alcoholic drink (like the martini held by this sophisticated cat). Water and ethanol (99% of these drinks) are miscible, so are always at least a solution with one another. The additional flavor compounds that make drinks different from one another tend to be in solution as well.
Keeping in mind that a single axis for progress is reductive: also, don’t forget that there have been and will be backslides. For example, European colonialism set back a lot of progressive / alternative cultures, genociding them or converting them to something that better-served the interests of empire (e.g., race rules).
You can burn em with your burner of course. I haven’t burned discs in so long that I can’t remember what software I used to use, but there should still be open source, free software that can do exactly that.
If long-term, secure storage is your goal I’d go with redundant, error-correcting digital storage with off-site encrypted backups (don’t forget the password!). A proper system like that will survive a tornado (because it’s backed up off-site). A home-built RAIDZ2 NAS with one of many off-site backups will work very well. If you don’t want to figure out how to build that system, you can also just buy a NAS with a similar level of functionality (I do still recommend RAIDZ2 with at least 6 disks, though).
Blu-rays will eventually degrade, either from scratches or a slow phenomenon where they get little holes in the foil. Even if you keep making copies, you’ll run into this problem. Of course, data corruption can also occur for files on a computer, but that’s why you use a strategy that keeps ~3 copies of each file around (basically what RAIDZ2 accomplishes) so that errors can be auto-corrected.
There are other benefits to a NAS as well. You can store your own backups of your other devices there as well and have them backed up off-site. You also have the option to share your blu-ray rips over your home network, basically running your own local streaming service.
If you want to share the love, so to speak, the bandwidth of a USB hard drive is actually pretty great.
Most veg Indian food has dairy added tho. Avoiding ghee is like going through an obstacle course of nice aunties and uncles trying to feed you. And don’t even get me started on curd.
Indian vegans also often use substitutes. I’m for vegan food unity: don’t harm and exploit animals and I support you.
