I actually wanted one day to see the Booru On Rails’ source code, but looks like I never will :-(Don't worry, we're still releasing it. I've committed to a hard deadline on the release — Dec 25, 2019.
The old code is tested and proven to work. The new code… it’s not. Rewriting working code in a new language (that I’m not even sure what it is called) is a known way to fail.
I'm painfully aware of this. My plan is to develop and test incrementally. We'll be running Derpibooru and Philomena in parallel for a while to assert that Philomena works without major hiccups. This will be hosted at philomena.derpibooru.org.
How come the old code is now, suddenly, too slow, when it has worked just fine for 8 years?This is something I'll be covering in an upcoming patreon post; hang tight.
