Dark Sky didn't have "powerful forecasting." They literally just had a simple computer vision app which used optical flow to track blobs and weather radar, and then they extrapolated those blobs forward.
- brewdad 3y agoIt was a tool that was either very accurate or inaccurate depending on your perspective. If DS said rain would be starting in 8 minutes, it almost always rained at my house very soon thereafter. Very accurate. However, sometimes that rain came 4 minutes later or perhaps 12 minutes later. Now the forecast was off by a factor of 50%. Could be no big deal or a thing that ruins your morning depending on whether you got caught out in it and expected to by dry or not.
- counters 3y agoWell, tracking a rain blob on radar that is 8 minutes from your house is an extraordinarily linear problem, so not surprising they'd have absurdly high P/R for that forecast :)
