Welcome to the ninth ##java podcast. If we were using octal, we’d be on the eleventh podcast by now.

This can save time on some optimizations, but it’s understandably limited (and should be). The Halstead Metrics (also known as “Halsted metrics”) discusses code complexity in Java.

Technical Itch: JVM guaranteed safepoints, Safepoints in HotSpot JVM, and Dynamic Deoptimization came up in conversation. javap.yawk.at – selckin says it’s basically “take a peek under the hood at the java bytecode for fun and profit.” Interesting site, though, it basically runs javap and procyon (a java decompiler) over submitted code and shows you the bytecode and associates it with the lines of java (or kotlin, or scala) that generated that bytecode. NetBeans...
