Since “trending” can mean a lot of different things as far as how it’s computed, here’s how I’m currently doing it [1]:<div class=""><br class=""></div><div class="">Using a look back over the last 30 days of downloads I compute a “zscore” for each project for yesterday (effectively, how many standard deviations away from from the mean yesterday was for that project in total downloads). The trending projects is then the top 5 projects in terms of zscore for yesterday (recomputed every day at ~3am UTC). Because it’s a lot easier for a project with an average of 5 downloads to jump to 100 than it is for a project with 50000 downloads jump to 1000000 I have tried to exclude any projects with very few downloads from this, so in order to qualify to be trending a project must receive at least 5,000 downloads in a month.</div><div class=""><br class=""></div><div class="">If you happen to be some sort of sciencey person and you know of a better way to query what is effectively a table with a row for every download for every project to determine which ones are trending, feel free to open an issue or create a PR or something. I don’t really know what I’m doing here :)</div><div class=""><br class=""></div><div class="">Anyways, that’s all! <br class=""><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">[1] <a href="https://github.com/pypa/warehouse/blob/a36435b9865000cdaae97b948af48c33f7d8fe8e/warehouse/packaging/tasks.py#L19-L102" class="">https://github.com/pypa/warehouse/blob/a36435b9865000cdaae97b948af48c33f7d8fe8e/warehouse/packaging/tasks.py#L19-L102</a><br class=""><div class="">
