问题 I currently creating a cross platform desktop application using Electron. I wish to add analytics to view user metrics. When I try to find for existing packages that provides metrics info, I found electron-ga. The package uses GA to track user metrics and to set it up I need to include GA tracking id in my app. My question is, if I include the tracking id in an electron app and distribute my app, everyone can look at the tracking id and steal it right? I would like to know if using this

问题 How do I subtract two timeseries in Grafana? Or add two together, divide one by another, etc...? I have found vague hints online about taking differences between timeseries, but nothing that actually tells me how to do so. I'm using Grafana v2.0.2 with Influxdb v0.8 and have played around with the graph controls enough to discover things like the difference operator I can apply, but I have no idea how to use it. I've attempted to find documentation on this, but the closest I can find is

问题 Problem I need to compute the Pearson and Spearman correlations, and use it as metrics in tensorflow. For Pearson, it's trivial : tf.contrib.metrics.streaming_pearson_correlation(y_pred, y_true) But for Spearman, I am clueless ! What I tried : From this answer : samples = 1 predictions_rank = tf.nn.top_k(y_pred, k=samples, sorted=True, name='prediction_rank').indices real_rank = tf.nn.top_k(y_true, k=samples, sorted=True, name='real_rank').indices rank_diffs = predictions_rank - real_rank
