I’m at a Cloud Foundry conference today. Cloud Foundry is an open source “cloud” platform as a service (PaaS).
I decided to dive in and try to deploy the server we developed at GiveCamp last week for the ‘Big Brothers and Big Sisters’ charity project. I started by mavenizing the project, so I had a war to deploy.
Then, I created a free Cloud Foundry account, installed their ‘vmc’ command line tool and ran the ‘vmc push’ command to deploy my way to the cloud. And it worked straight off! Don’t you just love it when tools just work?
Our webservice is now running on a remote server that can be accessed by the iPhone and Android apps the team is developing. We still have some database work to complete, but this feels like a nice step forward.
In the mean time, I am now officially a Cloud Foundry fan…
Had a great weekend at the Central California GiveCamp in Fresno this weekend. I joined the Big Brothers and Big Sisters team, working on a mobile app (Android & iPhone). I helped out on the server & database side where we created a Java WebService talking JSON, with a MySQL database. Most of the team were from Fresno State. Still some work do to deploying the solution to the cloud, but we made good progress.
It was a really enjoyable weekend, and all for a good cause. Thanks to Walt Read and Iran Rodrigues for setting up and running it all so smoothly, and Dr Alex Liu from Fresno State for organizing the team…
Heading to Central California GiveCamp tomorrow for a weekend of coding for charitable causes. Should be fun!
This morning’s Keynote at JavaOne contained a few interesting announcements, including
- JDK7 for MacOS X Developer Preview announced by Hasan Rizvi (SVP @ Oracle). Available here.
- Java FX to be open sourced, and it will be proposed to the JCP (Confirmed, see press release)
- JDK8 will be released in the summer of 2013 (not 2012 as previously discussed), as announced by Adam Messinger from Oracle
There was also mention of an Oracle Java Magazine, which I confess I had never heard of before.
For a summary of this morning’s announcements, see here.
Overall, not the most exciting keynote I have seen. It opened with a presentation from Juniper Networks. I didn’t find the topic of “Programming the network” to bring networks and apps closer together particular relevant for me personally. They then rolled out a bunch of other corporate folks from the likes of Intel, Redhat, IBM and ARM. The Twitter guy did announce that Twitter are joining OpenJDK as well as the JCP though.
On to the sessions…
I am at JavaOne 2011 right now. Always fun and it seems to be bigger than last year, with a huge selection of talks and presentations (although frustratingly flaky wifi!).
Some of the themes of this morning’s keynote talk were JavaFX 2.0, what will be coming in Java 8 and a new Oracle NoSQL Database. There are some links here, here and here (and I believe the videos will be posted soon here).
I just attended a very useful Java Web Framework comparison talk that I will try to post about shortly. I also met up with some of the DZone team. For now, I am going to some JavaFX talks.
If any of you are attending, let me know!
I posted some notes about my final day at JavaOne to theServerSide. At the moment, currently on the front page. Cool 🙂
WebSockets is a technology that enables bidirectional communication between web browsers and server side processes. It provides a persistent connection between client & Server, hence enabling ‘push’ abilities where you can push data/notification to browsers from the client. Other client communication options to compare it with would be Ajax
and Comet (basically Ajax with long polling).
I spent the afternoon of Day3 at OSCON attending two interesting database scalability talks. The first was on Database Scalability Patterns; The second on Database Sharding (and Spider for MySQL).
All my notes are below…
I have seen several talks on Google App Engine before, but have still not used it in anger, so this talk, Introduction to Google App Engine, acted as a refresher. It was given by Ikai Lan, a software engineer working for the Developer Programs groups at Google.
Google App Engine is a way to run your applications on Google infrastructure. You push your code to App Engine and it gets scaled out depending on how many instances you need.
