🎉 New year, new version of Gatherers4j! Announcing v0.13.0 with several new gatherers: • uniquelyOccurringBy() which limits a stream to uniquely occurring elements • Median, Min, and Max with moving (look-back window) and running variants 🔗 Release notes: github.com/tginsberg/ga...

It's the time of year when subtle #Java date formatting bugs tend to appear, often caused by using the wrong year format. I’ve written a post explaining what’s going on, how to fix it, and how to prevent it in the future. todd.ginsberg.com/post/java/be...
