If you read the article they do give merchants more value in the form of 2% lower fees. It's just that that's not enough.

The article says they're a 10 person family.

Kindof unrelated to the article, but I was recently wondering if it would be possible to detect and deny pointer cycles in a language in an efficient way, so that you could then use simple reference counting instead of full-blown garbage collection.

It probably wouldn't be usable for a general-purpose programming language, but for a special-purpose scripting language I could see it making the language implementation easier.

I hadn't heard of bcachefs, but I looked it up and apparently Linus just removed it from the kernel source tree last month for non-technical reasons.

The author bashes other algorithms for being "arbitrary", but I don't see how FSRS is any less arbitrary.

PCs don't have sandboxing or permissions.

How loud is it? Would it disrupt the whole office if I had it on my desk and occasionally played with it?

Very cool, I'll check back for the Kickstarter!

Having the MD file and the website open side by side and being able to see immediate updates as you write is valuable.

Similarly to the bubblewrap comment, I'd also like to know how it compares to nsjail.

I think nsjail uses mount namespaces (CLONE_NEWNS) instead of landlock for filesystem sandboxing, but what would the practical differences be?
