UTF-8 is both "binary" and "text" at the same time. :) It's binary because the UTF-8 standard states how each Unicode code-point (i.e. character) is to be translated into a series of bytes. But, because each (corre

The main highlights (for me) are support for `backup --read-concurrency` to control the I/O pressure on the underlying file-system and disks and `backup --no-scan` which also helps. (I'll have to test these options myself, plus t

Yes, the Cloudflare web-analytics does require JavaScript. With regard to no-JavaScript sites I understand; and for example the only JS on my site is the one for GoatCounter and Cloudflare web-analytics. GoatCounter does fallback nicely i

No, with Cloudflare you can use for free the "web analytics" product; you can even use it for any site, not only those hosted at CloudFlare. (Perhaps what you've seen is the "cache analytics" or "traffic anal

You could also just throw a CDN in front of Netlify (I do this with Cloudflare) and it will be extremely hard to reach that limit.

[the author here] Indeed I mention Cloudflare quite a lot, and that is for two reasons: (A) If you do want to have a performant website (be it static or dynamic) you do need a CDN with edge caching; else the physics with it's insist

For example in one production deployment, Kawipiko is used to serve a snapshot of a former dynamic web-site that is now conserved. That snapshot has around 600K files and would eat around 12 GiB of storage; but with Kawipiko all that is b
