Carnegie Mellon University has introduced Fray, a concurrency testing tool for JVM programs to catch bugs and replay them. Written in Kotlin and based on this research paper, Fray can't find all concurrency issues, but uses recent research to maximize the chances of detecting them. Fray uses shadow locking, a technique that incorporates extra locks to mediate access to shared resources in a specific order.
Prepare to be surprised when we compare Python and Kotlin for simple programs, loops, imports, exceptions, and more. You can also get a super early preview of Python's next-generation (Python 3.15) sampling profiler, get up close with AWS's new AI-powered Zed editor, and explore your options for AI/ML programming outside of the Python ecosystem.
"You cannot do industrial programs in English," Skrygan says early on in our conversation, directly challenging the notion popularized by Nvidia's CEO that even the toughest coding tasks can become approachable through natural language alone.
