James Gosling (Father of Java) Loves Jelastic

Recently, we posted an article about James Gosling here on the blog (Where is the “Father of Java?”). It got a lot of attention because James hasn’t been in the news that much until just recently. His latest project has started to get a lot of attention and, of course, as soon as we started hearing the buzz around it, we were immediately interested and started following along and keeping track of what James was doing more actively. As we were watching one of his latest talks, Robots and Water and Whales, Oh My!, we were blown away when he dropped the news that he is not only using Jelastic, but loves it! He did share it in his typical understated way, dropping it right in the middle of his talk about his current project.


“The Father of Java” Loves Jelastic

As far as we can tell, this is the first PaaS that Dr. Gosling has given his seal of approval. We reached out to him to confirm it, and sure enough, it turns out that he is a very happy Jelastic user and is very excited about what he can do with it and what he will be doing with it in the near future.

Though I know that in our community, most everyone knows who James Gosling is, there a lot of younger guys learning Java that have never heard of him, like my 13 year-old brother, Daniel, who is quite an avid Java coder. So, who is James Gosling?

The Dr. James Gosling Bio

This bio comes from Gosling’s own blog: James Gosling received a BSc in Computer Science from the University of Calgary, Canada in 1977. He received a PhD in Computer Science from Carnegie-Mellon University in 1983. The title of his thesis was “The Algebraic Manipulation of Constraints”. He spent many years as a VP & Fellow at Sun Microsystems. He has built satellite data acquisition systems, a multiprocessor version of Unix, several compilers, mail systems and window managers. He has also built a WYSIWYG text editor, a constraint based drawing editor and a text editor called `Emacs’ for Unix systems.

At Sun his early activity was as lead engineer of the NeWS window system. He did the original design of the Java programming language and implemented its original compiler and virtual machine. He has been a contributor to the Real-Time Specification for Java, and a researcher at Sun labs where his primary interest was software development tools. He then was the Chief Technology Officer of Sun’s Developer Products Group and the CTO of Sun’s Client Software Group. He briefly worked for Oracle after the acquisition of Sun. After a year off, he spent some time at Google and is now the chief software architect at Liquid Robotics where he spends his time writing software for the Wave Glider, an autonomous ocean-going robot.

Ocean Robots? Where’s the Java?

In August of last year, after leaving Google, Gosling joined a California-based startup called Liquid Robotics as their Chief Software Architect. Liquid Robotics makes data collecting ocean robots. Many US research institutions, as well as government and private sector customers use their robots to collect oceanic data. Their robots, the Wave Gliders unmanned maritime vehicle (UMV), are about the size of a surfboard. They are powered by sunlight; something that there is an abundance of on the oceans—so no worries about running out of power or having to refuel. They use that sunlight that is converted to power to run any number of on-board electronics and sensors. And one of the coolest things about the Wave Gliders is how they take advantage of wave-motion to power through the water, giving them an endless supply of energy.

Why the oceans? Why not space?

The truth is that we know more about space than we do the oceans here on our own planet. There are a myriad of reasons what it is important to better understand the, but at the very least, we could predict weather better, understand how the oceans influence climate better, better understand marine life and get to know the thousands of species that we have yet to discover and reduce the costs of running things like buoys. The students at SCAD made the following video for Liquid Robotics as part of their entry into the Savannah Ocean Exchange’s Gulfstream Navigator Award, which they won last year. The award recognizes “solutions that positively impact our ocean and coast.” Gosling said Liquid Robotics has “a technically interesting challenge, that could save the world, and is economically viable—these three things don’t come together that often.”

The oceans are vast and for the most part unmeasured. We are critically dependent on it and don’t know that much about it. The current methods for collecting data are very cost prohibitive. If you want to go very far out at all, the cost for just running a ship to do that is over $100,000 a day! And weather buoys cost at least $2 Million a year to run, and most of that is just paying for the ship to drop it off and for the cost of running a ship back out there to repair it. But what if would do things like understand hurricanes better and could accurately predict tsunamis? Right now, this data is very expensive and we don’t have that much of it; but what if we could get tons of data and make it cheap at the same time? This is what James Gosling is working on at Liquid Robotics.

Liquid Robotics and the Wave Glider

Basically, the Wave Glider is mobile, ocean going platform for sensors. To be more precise, it is a wave-powered UMV that presents a totally new method and approach for constant presence and data collection in the ocean. It combines both an underwater vehicle and sea-surface vehicle to make something of hybrid UMV. The underwater vehicle is where the Wave Glider gets the glider part of its name. The underwater glider is linked to the floating platform by a cable.

The Wave Glider uses the differences between the water’s behavior below the water and on the surface to propel itself: essentially converting the ocean’s wave energy into forward thrust. What’s even cooler though, is that the forward motion is independent of the wave’s directionality. This is the most unique part of the Wave Glider and what makes its goal of gathering the oceans’ data possible. Its propulsion system, or more accurately, it wave energy conversion system for propulsion, is what makes it so unique. With its system, the Wave Glider has unlimited propulsion, for free.

A wave that is rising will lift the surface Float, which due to the tether causes it to rise as well. The wings that you can see on the above video, articulate as they are pressed down on the upward motion of the Float and cause the motion of the Sub to go upwards and forward, pulling the Float forward and away from the wave. This then causes the Sub to drop, making the wings pivot again, moving the Sub down and forward, pulling the Float along again.

Streaming Telemetry

The part of the Wave Glider project that Gosling is running on Jelastic is the streaming telemetry bit. When they get the telemetry data off of the Wave Glider craft, that have to manage all of it; and this is something that he is actively working on using Jelastic. The current system that he has in place (and you can see this in the video 4min before the part about Jelastic) has a number of properties that he describes:

  • It’s lightweight
  • Very specialized
  • Non-EE, JMS-ish thing
  • Very Simple
  • Optimized for small things that flow
  • Every chunk has to be individually authenticated
  • Authentication is extremely important because every data sample from every wave glider can potentially be differently authenticated
  • Not trying to be general purpose
  • The real key is simplicity
  • It is not a big data problem: in fact, data needs to be really small due to the cost of sending it ($1/kb), add that up…
  • Failure would leave fleets of flailing robots and tons of money lost

Why is he using Jelastic and not Amazon, Google or Microsoft?

In his talk, Gosling says that he was careful to not use any special APIs or ISPs. ISPs like Amazon, Gosling said, “Have had a number of incidents where they had a number of software bugs that took out an embarrassingly large part of their infrastructure.” So, he was careful to avoid people like Amazon, GAE or Microsoft Azure, where special APIs are a huge part, and possible liability, of their solution.

He wanted to build clusters that could cross ISPs. In doing so, he tried three different PaaS solutions, but stopped to say how much he liked Jelastic, how well it was working for him, how he likes the setup, backend and UI.

“I really like Jelastic. It’s actually software package that a number of ISPs are using. It’s a Java hosting system and so you don’t get a bare Linux machine. What you get is a JavaEE container, and you can drop WAR files on them and they have this really nice control panel where you get a slider that says how many clones of Glassfish do you want and check boxes for [databases]. You don’t have to go into Linux – Oh my God, what it takes to install anything: it’s like which version of Linux is compatible with which app server and what time… they actually take care of that and it works lovely. I actually built these clusters and they can span multiple ISPs, multiple countries, multiple datacenters, and that’s how I deal with my personal extreme paranoia of the survivability of these things.”

Why Jelastic is Better

Though his words speak for themselves, it’s worth repeating that Jelastic doesn’t approach the PaaS as do other providers. If you are worried about simplicity, survivability and decentralization, Jelastic is the easy answer.

Proud to be recommended by James Gosling -

“I’m a happy user of Jelastic”

We are quite proud of what we have created with Jelastic and having “The Father of Java” praise Jelastic is an honor that we could have never expected or foreseen. To have him using our product for not only his work but, as he told us by email, using it for “a bunch of stuff” and his personal projects has confirmed our belief that developers have been looking for something like Jelastic. It just didn’t exist until now.

Dr. Gosling has already tried Jelastic, liked it and continues to use it, and we hope that if you haven’t given Jelastic a try, that you will. We are confident that you to will be a happy user of Jelastic. In the mean time, Gosling has said he will continue working on his fleet of sea robots.

    Hi Judah,

    That’s the first time I hear the father of Java talk – thanks for sharing that video. Although I don’t use Java in my development, I think that you being mentioned by him (not only he mentioned you, he said he loved your product) is a great compliment to your product.

      No doubt. It’s a great video as well to get an idea of the calibre of guy it is that created Java. The guy is rolling in fun tech stuff a notch above what I’m doing, but they way he explains it is awesome! Makes me want to buy one of those Wave Gliders…

      Thanks for coming by the blog. It’s because of comments like yours that we keep this up. :)

  5. Jelastic Wins Duke´s Choice Technology Leader Award: The Java Community´s Oscar

    [...] A testament to Jelastic´s innovation is the fact that another Duke´s Choice Award Winner, Liquid Robotics, is using Jelastic as well. Liquid Robotics´ Chief Software Architect, Dr. James Gosling “The Father of Java”), has chosen to use Jelastic for its stability, redundancy, scalability, time saving and survivability. As he put it, “I really like Jelastic… you don´t get a bare Linux machine… they actually take care of that and it works lovely… they can span multiple ISPs, multiple countries, multiple data centers, and that´s how I deal with my personal extreme paranoia of survivability”. With Jelastic, Gosling doesn´t have to worry about his robots being lost at sea; he can focus on the development and functionality of his applications and the work his ocean-going robots are doing:http://blog.jelastic.com/2012/08/23/james-gosling-father-of-java-loves-jelastic/ [...]

    I simply had to thank you so much all over again. I do not know the things that I could possibly have achieved without these techniques documented by you regarding my topic. This has been a real troublesome condition in my position, however , encountering the very specialized fashion you handled it made me to jump over gladness. I will be grateful for your work as well as trust you really know what an amazing job you were accomplishing teaching some other people through your web site. Probably you haven’t encountered all of us.
