Great news for Java developers! New major release of one of the most popular programming languages is out now!

Java SE 9 is the latest update to the Java Platform. This release includes much awaited new features like the modularization of the Java Platform, better performance, support for new standards, and many other improvements. 

What's new?

  • Modularity
    • New, controversial modularity capabilities are based on Project Jigsaw. Modularity—in the form of the Java Platform Module System—divides the JDK into a set of modules for combining at run, compile, or build time. Modularity has been called a “transitive” change, enabling understanding of dependencies across modules. This feature is designed to let developers more easily assemble and maintain sophisticated applications.
  • Compiler improvements for Java 9 code
    • The Java 9 upgrade features several new capabilities for compiling code, chief among them is ahead-of-time (AoT) compilation. This is in an experimental phase, this feature enables compilation of Java classes to native code before being launched in the virtual machine. This feature is designed to improve startup time of both small and large applications, with limited impact on peak performance.
  • REPL
    • Java 9 has a read-eval-print loop (REPL) tool. Java 9’s REPL is called jShell. It interactively evaluates declarative statements and expressions. Developers can get feedback on programs before compilation just by entering some lines of code

And some smaller updates and improvements:

  • Steam API improved
  • JavaScript backing improved
  • HTTP/2 client support
  • HTML5 and unicode support improved
  • DTLS security API is added

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.
