Yeah, found this out the hard way with customers complaining that they hit save, get an error code "0", and then couldn't save again because we had disabled the button after submitting.
Side rant: can I take a moment to call out WHATWG for deciding to specify that all networking errors in XmlHttpRequest get status: 0 and absolutely no explanation anywhere in the response object ( see https://fetch.spec.whatwg.org/#concept-network-error ), making it absolutely a nightmare to diagnose problems and support our users? I suppose in a world of fail whales and cute cat pics, leaving the user in the dark as to why something broke is now standard practice, but at least in those cases there's something server side to let techs know what's going on, but I get random calls from users complaining about this and the best I've got is that they tried to leave the page while the form was still saving (this triggers the error handler too since it's the exact same code) or their internet connection dropped ever so briefly because the next words out of their mouth when they say that is "but I can view other websites".

and in their spec for "network errors" at https://www.w3.org/TR/2012/WD-XMLHttpRequest-20120117/#reque... unless you're using it in synchronous mode, it just sets the error flag. There's an onerror callback, but it doesn't appear to get any information about what went wrong than the WHATWG version.
What Qubes is is a Xen hypervisor (as I understand it, hypervisor independence is a work in progress) with a particular configuration and set of tools to serve as plumbing between various virtual machines and the dom0 host.
They distribute Fedora, Debian and Whonix domU guest images (and the dom0 host that is installed is Fedora), but you're free to install BSD, Windows, or whatever else you can get to run as a VM guest.
The question is whether people are all going to pull words from a very small pool or form sentences to cut the search space (adjective noun adverb verb noun). A search space of 2000^5 (2000 most common words without punctuation) is still about 20 times larger than 80^8 (upper/lower/number/symbols)
