Then, sum up how many "countme=1" GET requests we get per week, and you have a good count, without tracking individual clients, without inventing new uuids¹. Such a form of counting is so minimal that I think you don't even have to query the user whether he agrees with that in the installer UI. And the user knows that with the one additional bit of info he grants you every week there's very little you can do you couldn't do in the status quo ante. Morever, doing accumulation like the proposed also makes things extremely simple to account for, as you don't have to store per-client info in a huge database on the server. Instead it's entirely sufficient to have a single counter for each subset of distro you want to count. In the interest of privacy the valid desire to have statistics about the use of our distro needs to be implemented with data frugality in mind. Keeping a full database of all uuids of all clients on a Fedora server somewhere is definitely not data frugality if all you want is count. Even if Fedora wouldn't misuse the data, somebody might exploit the server and steal the database and there you go. Not even having the database is hence the much better approach, and you really need neither the database nor the uuid concept to do proper counting. So yeah, in the interest of privacy and simplicity, please don't got the uuid way, there are simpler and better approaches. Lennart (Footnote: ¹ if you are concerned that not every client is updated every week, then you could even slightly extend this and maybe submit countme=2 the first time within each 4 week period, and countme=3 within each 52 week period, so that you you catch even those though it will take a bit longer for them to accumulate them) -- Lennart Poettering, Red Hat _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
