No Network, No Data Pack: Messaging App Jott Is Your New Dream App
Only when we thought there was no need for yet another messaging app, a hot new messaging app is in news and for all good reasons. Jott, an instant messaging app lets you send data and texts without an internet connection.
Jott uses Bluetooth and Wi-Fi radios to create a locked network with other devices that are within 100-feet of each other. Jared Allgood, CEO and co-founder of Jott, said that the app targeted the teens, and the entire customer base of Jott consists of 13 to 18-year olds. Jott has been a hot commodity with the U.S. teenagers and kids and that success helped Jott close a $1.8 million seed funding round from numerous protruding venture capital firms.This messaging app startup has doubled its users to half a million active users in March and its user base is increasing with a rate of 15,000 to 20,000 users per day.
In the future, Allgood believes that Jott could be used for more than just teen texting, envisaging it as a possible lifesaver during a natural disaster. Since the connections are devised through the device, Joyy messages will get routed through in emergency situations and cases when cell phone towers go down and texts can no longer be sent through phone.
Allgood elucidated: “You could be on top of Mount Everest or on an airplane completely disconnected and yet still be able to send text messages.”
How Jott Works?
The usual text messages are first transmitted from your cell phone to the nearest cell tower and then they are directed to the person you are texting. On the other hand, Jott sends texts without any service provider by using something called mesh network that works on Bluetooth low energy (or router) that has a range of 100 feet. While instant messaging apps are the seeing an exponential growth, the usual texting is still common in schools as the teenagers want to make new friends but not each one of them has a data plan.
Explaining the privacy measures, Jayson Ahlstrom, Jott’s COO and co-founder said that Jott provides a level of comfort and safety measure and takes care of the teen’s security interests.
It would be interesting to see if Jott changes the game of texting in near future.

Java 9 is Coming – Release Dates
General availability of Java 9 is announced by Oracle and it is coming on Sep 22nd, 2016. The major feature in Java 9, the module system, will be a boon for developers and it will also bring improved scalability and performance to Java platform.
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.
Java 9 Release Schedule
|2016/02/04||All Tests Run|
|2016/04/21||Zero Bug Bounce|
|2016/06/16||Rampdown Phase 2|
|2016/07/21||Final Release Candidate|
We will be covering more on Java 9 as we get more information from Oracle. Stay tuned.

Who Invented Li-Fi?
The Li-Fi technology was originated in 2011 by German physicist Harald Haas, who outlined the idea of using light bulbs as wireless routers during a TED Talk. He demonstrated that with a flickering light from an LED, one could transmit more data than a cellular tower.
You can watch the full video of Haas talk about the Li-Fi technology in 2011 given above.
