GitHub repositories taking off in the last 30 days

How the ranking works

Stars gained
New stars in the window. "all" means the repo is younger than the window, so the number is every star it has.
Today
Stars since midnight US Pacific time, so a partial day.
Above pace
How many more stars the repo got than its pace in the window before would predict. +500 means 500 more than usual.
Momentum
A daily score modeled on trendshift.io: 8 points per star and 2 per fork since midnight UTC, reduced for repos that are this busy every day.
Speed-up
Stars per day in the window divided by stars per day in the window before. "New" means the repo is younger than the window. "Under 14 days" (twice the window; "Under 2 years" for 1 year) means it is older than the window but too young for a full window before it to compare with.
Bars
Stars per day (per week for 90 days and 1 year). Bright bars are the selected window. Heights use a square-root scale, so quieter days stay visible next to a spike.
