Philip Reames is a experienced software engineer with technical lead and management experience.

In this short video, Philip talks about Falcon, a new Just-in-time compiler (JIT) for the Zing VM. The goal is to replace C2. It is built around LLVM. 

Falcon features:

  • Azul’s new “Falcon” Just-in-Time (JIT) compiler is a new, highly optimized runtime compiler for Azul’s Zing runtime for Java (JVM)
  • Falcon is based on LLVM, the compiler infrastructure project backed by dozens of companies and hundreds of contributors advancing the latest capabilities in modern compiler technology
  • Falcon delivers substantial performance gains over Java’s legacy “C2” JIT compiler
  • Zing with Falcon achieves better application SLA metrics, reduces operating costs, and results in an improved customer experience

TIOBE Index June 2019 to be Rolled Out

Java is still on the top, but experts noted fast growth of Python search queries, and they believe it can reach 1st place in 3-4 years

June 2019 TIOBE Index has been released. Analysts noted a sharp increase in the proportion of searches for Python.

This month Python has reached again an all time high in TIOBE index of 8.5%. If Python can keep this pace, it will probably replace C and Java in 3 to 4 years time, thus becoming the most popular programming language of the world. The main reason for this is that software engineering is booming. It attracts lots of newcomers to the field. Java's way of programming is too verbose for beginners. In order to fully understand and run a simple program such as "hello world" in Java you need to have knowledge of classes, static methods and packages. In C this is a bit easier, but then you will be hit in the face with explicit memory management. In Python this is just a one-liner. 


Experts attributed the growing popularity of Python to the fact that now many have hit the development of software. And newcomers prefer Python - succinct and concise. According to analysts, Java for beginners is too verbose, and C sooner or later will force to understand the intricacies of memory management.
