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

Canonical to Represent Minimal Ubuntu

New version of Ubuntu is created for servers, isolated containers based on Docker and cloud systems

Ubuntu team presented a simplified version of the base image - Minimal Ubuntu. It is designed for servers, isolated containers based on Docker and cloud systems. The release features high performance, minimal load time and automation of applications in the cloud.

The small footprint of Minimal Ubuntu, when deployed with fast VM provisioning from GCE, helps deliver drastically improved boot times, making them a great choice for developers looking to build their applications on Google Cloud Platform.

The authors of the project emphasize the size of the distribution kit, which "weighs" 157 MB, and also supports the main cloud systems like Amazon EC2, Google Compute Engine (GCE), LXD and KVM / OpenStack, each of which has its own optimized version of the package. In addition, the OS-based image for operating with containers based on the Docker platform, compatible with the Kubernetes.

Minimal Ubuntu is designed for automated execution, so it includes only a minimal set of tools. The distribution can be upgraded to a set of Ubuntu Server packages using the special utility "unminimize", which returns components that are convenient for interactive management.

According to Canonical representatives, the deletion of the manual control functions resulted in the acceleration of the load time by 40% and the reduction of the occupied disk space by 50%. At the same time, this release remained completely compatible with all the packages from standard Ubuntu repositories. Required packages can be installed using the standard package manager apt or using snapd, which are included in the distribution by default.

Two assemblies are available for download, based on Ubuntu 16.04 LTS and 18.04 LTS. You can download them on the official website.
