Java 9 Released — 9 Biggest Features and Download Links Are Here


JDK 9 is the first major upgrade to standard Java edition since March 2014. It comes loaded with tons of new features, which makes it a pretty exciting release for developers.

Java 9 features: Brief overview


Project Jigsaw — Module System


The major change in Java 9 comes in the form of Project Jigsaw, which is an all-new module system. It’s the most important feature of Java, that has also received tons of criticism. This feature will bring modularity to JDK, run-time images, Java source code, etc. The developers can also create their own modules and simplify the code.

JShell


With JDK 9, now you can fire the JShell from the console and go crazy with your Java code. JShell allows you to test different Java constructs without any hassle.

Stream API enhancements


With Stream API enhancements, Java 9 comes with the added methods to conditionally take or drop items from the Stream, create a Stream from nullable value while expanding Java SE APIs, etc.

Process API Changes


With Process API improvements, Java 9 ensures that OS process are controlled and managed in a better manner.

Segmented Code Cache


With the help of Segmented Code Cache in JDK 9, the code cache can be divided into different segments. Each of those segments can contain compiled code of a particular type. This Java 9 feature is expected to improve performance.

Ahead of time compilation


While it’s in the experimental stage, AOT-compilation is expected to improve the startup time of applications.

New HTTP 2 Client


Java 9 features list is incomplete without the mention of a new HTTP client API for implementing HTTP/2 and WebSocket. It’ll improve web page loading times, performance, and reduce resource usage.

Parser API for Nashorn


JDK 9 ships with a parser API for Nashorn, whose goal was to implement a lightweight high-performance JS runtime in Java with a native JVM. This API ensures better Project Nashorn JS support

Other major-minor features


The other Java 9 features are:


  • Multi-release JARs
  • Process API updates
  • Garbage Collector improvements
  • Better Javadoc
  • Private interface methods
  • That’s not all; The list of Java 9 features is even longer. You can find the complete set of features in the release notes.

CREDENTIAL HARVESTING VIA MITM – BURP SUITE TUTORIAL

Image
    In this step by step tutorial we will discuss some of the more advanced use cases for the Burp Suite.  Credential harvesting through Man In The Middle attack vectors can be your saving grace during an otherwise uneventful penetration test. This guide is intended to be educational as well as entertaining.  The author does not condone or encourage illegal hacking activities. ENABLE ROUTING     The first thing you’ll want to do is enable your attacking machine to route traffic.  This way, when your victim machine makes a request to an external HTTP server you will forward the request and intercept the server’s response.  This behavior is necessary for credential harvesting attacks. If it helps, you can think of yourself as an interception proxy much like the one we are using in this tutorial. $ echo 1 > /proc/sys/net/ipv4/ip_forward #ProTip  When you try this on your own and things inevitably don’t work as easily as I have described them, check this first!

Kotlin/Native IDE Support Preview

Image
Kotlin/Native is  a brand new technology  that compiles Kotlin directly to machine code and produces executables that can run without a virtual machine. At KotlinConf 2017, we announced a preview release of development tools for Kotlin/Native. While we have IntelliJ IDEA for working with Kotlin, Kotlin/Native integrates with technologies from the native world such as Clang and LLDB support. That’s why JetBrains’ choice for Kotlin/Native is  CLion , our IDE for C and C++. To get started, download and install  CLion 2017.3  (note that this version is at the early access preview stage for now). Next, install two plugins from the JetBrains  Plugin Repository . In CLion, choose  Configure → Plugins → Install JetBrains plugin… , then find Kotlin and Kotlin/Native plugins there, and install them. Don’t forget this is still a technology preview and bugs are possible, but if you encounter any, please  report them ! New Kotlin/Native Project Learning a new technology requires a good
