There were a few folks with very reasonable questions about the 🔢 Numbers section of this email, hopefully this helps:
📈 A sparkline explainer 🌠
The 🔢 Numbers section of this email had sparklines:
- Sparklines are small graphs of a set of numbers
- 1, 2, 3, 4, 5 looks like ▁▃▄▆█
- 0, 1, 0, 1, 0 looks like ▁█▁█▁
- There a are 5 bars, each is a train version
- from left to right: 1.37.0-wmf.20, 1.37.0-wmf.21, 1.37.0-wmf.23, 1.38.0-wmf.1, 1.38.0-wmf.2 (latest)
- Metric key:
- Patches: # of changes we deployed with the train
- Rollbacks: # of times we undeployed the new version due to problems
- Days of delay: # of days we delayed the new version due to problems
- Blocking tasks: # of tasks we had to investigate before full deployment
All these numbers come from
our "train-stats" repo. Hopefully, that's helpful for the curious or confused.
