JAVA 9 RELEASE DATE AND ITS NEW FEATURES
Java 9 release dates and roadmap is finalized by Oracle and you can expect it to be available by Sep 22nd, 2016. If you are interested in trying it out now, the early access version of JDK 9 is available here. The milestone definitions for JDK9 are the same as those forJDK 8.
Modularity via Project Jigsaw is a key feature of Java 9. Java 9 will treat modules as a fundamental new kind of program component, with the system improving scalability and performance, a key Oracle Java official says.
In a blog post this week, Oracle’s Mark Reinhold, chief architect of the Java platform group, discussed the goals of the module system. Chief among them is reliable configuration, to replace the “brittle, error-prone, class-path mechanism” with a means for program components to declare dependencies on each other. Strong encapsulation, which allows a component to declare which public types are accessible to other components, is also a goal.
“These features will benefit application developers, library developers, and implementers of the Java SE Platform itself directly,” said Reinhold. “And indirectly, since they will enable a scalable platform, greater platform integrity, and improved performance.”
Reinhold defined a module as a self-describing collection of code and data. Code within it is organized as a set of packages containing types, essentially classes, and interfaces. Data within modules includes resources and other kinds of static information.
Other than Project Jigsaw and Modularity to Java 9 platform, some of the other notable features worth mentioning are –
  • jshell – a new command line tool for Java that will add native support and popularize a Java way to REPL (Read-Eval-Print-Loop).
  • JMH – a Java harness for building, running, and analyzing nano/micro/milli/macro benchmarks.
  • Probably G1 as default garbage collector.
  • Full support for HTTP 2.0 and feature a new HTTP client for Java that will replace HttpURLConnection, and also implement HTTP 2.0 and websockets.
A list of other features coming along with Java 9 is listed here by Oracle. You can also check the countdown page for Java 9 and subscribe to get latest updates and it approached the release date.

22 percent of institutional investors already have exposure to digital assets. This is according to a new report by Fidelity Investments, one of the largest asset managers in the world. The report goes against many crypto skeptics who have been quick to state that institutions are no longer interested in digital assets. The survey polled 441 institutional investors between November last year and February this year. Interestingly, this was a time in which cryptos hit their lowest levels. Nevertheless, institutional investors remained unfazed, with interest in digital assets never really dwindling. Tom Jessop, the president of Fidelity’s digital assets division explained, “We never saw a decline in interest or sentiment during the crypto winter.” The survey revealed that 47 percent of institutional investors view digital assets as “having a place in their portfolios.” The investors, who include crypto funds, also disclosed their preferred investment methodology. 72 percent prefer to

INTRODUCING "DEEP WEB" THAT LIES BEYOND GOOGLE   The entire expanse of the Internet, going well beyond what you surf every day, is only the tip of a massive iceberg, the size of which is too vast to be known. Far beyond searching the Web with Google or chatting with friends on Facebook, there’s a dense maze of websites that exist out of view, though for how long that will be true is unclear. When most users log on to the Internet, they visit their bookmarked pages or use Google to search for sites that can provide the information they’re looking for. That Internet, used by billions around the world every day, is sometimes known as the  Surface Web , or the Clearnet, as coined by Tor and other anonymous online users. The Deep Web, simply put, is everything else. It’s made up of tens of billions of sites that are hidden within a universe of code — various estimates have put the Deep Web at anywhere from five to 500,000 times the size of the Surface Web.
