Mark your calendars! Aaron Bartell is coming to NH

Aaron Bartell will be speaking to the NHMUG user group on March 7, 2012

Mobile Dev for RPG Programmers

This power packed seminar is geared towards a half day (3.5hrs to 4hrs) of presenting. The focus is on mobile development for RPG programmers and dives into many areas including showing how to do the complete setup of a programmers desktop environment for Android development and producing a first Hello World program, all the way to doing HTML5 mobile development. After doing initial introduction I dive further into the technologies to show some real-world applications I have developed that show how one can leverage their RPG knowledge and take their company to the next level without leaving the IBM i platform. All tools and utilities are free and open source so all attendees can try them at no cost to their business!

Exploit the Power of Open Source Java from RPG

In this session you will learn how RPG's Java interface extensions can be used to exploit the wealth of Java Open Source applications. We will start by explaining the basic RPG syntax extensions and demonstrate how the interface works through practical examples. Examples will include: Interfacing with the Twitter API to easily send tweets (a.k.a. status updates) from your RPG programs Creating QR codes interfacing with Zxing API's from the community and Google Building pie charts, bar graphs, and more buy interfacing to the APIs We will also discuss how the performance of such Java utilities can be improved through the use of server job and data queue interfaces.

I got a wild hair the other week and decided to buy domain because I am on a mission to prove to IBM that all these Java tools they keep coming out with aren't giving my RPG shop what I need to keep my business at the highest level of the market competitiveness - too many layers of technological bureaucracy to do simple business applications.

My mantra is there is very little RPG can't do. So why not put that mantra to the test by creating an application for Android and web?

Picture this: Your child gets their first Android phone, and you would like to know where they are and what they do with the family vehicle, so you install a small application that uses the phone's GPS capabilities to feed coordinates to an IBM i server on the internet. The IBM i server is running Apache and RPG to receive the data into DB2. All the while the parent logs into a web interface, built using only RPG on the server side, and review, in near real-time, where their child is located by watching a GoogleMap. Pretty cool, eh?

This session will guide you through the steps necessary to develop both the Android and server side RPG code to accomplish the project. All tooling utilized to create the project is free and open source!

Web Serving with the Integrated Web Application Server

The integrated Web Application Server is the foundation for many Web based interfaces within IBM i. The IBM i team uses this Web container for a wide array of web based interfaces, learn how you can also make use of this technology. This best part, the Web Server is part of the IBM i operating system, no additional products to install, no foreign install mechanisms to run.

Web Services for the RPG programmer

Introduction to Web Services and why they are important. We will show you how the RPG developer can quickly both deploy their own Web Services (ie make an RPG program callable from the Web!) and how to easily call a Web Service from your native RPG code. Best news: you already have this support on your system! There are no new tools to buy or install.

Revolutionize Application/System Support with IBM Application Runtime Expert for i

Are you concerned about the resources it takes to deploy new applications as well as maintaining your existing ones? Have you ever spent hours troubleshooting an application issue, and thought “there must be a better way to figure out what is wrong”? Are you looking for ways to improve the efficiency of application validation and problem determination? If so, then the IBM Application Runtime Expert for i is for you.

The IBM Application Runtime Expert for i (ARE) is a new product that has the potential to revolutionize how you support and service your applications and systems. ARE provides a methodology for ensuring consistent deployment and performance for any type of application workload and the system environment it runs in. With this methodology, you have the opportunity to reduce the amount of time and money required to support your applications and the systems they run on. In this session, you will learn how ARE can be used to make application deployment and support faster and more efficient. There will be a demonstration of its intuitive, easy to use graphical interface, which allows users to start making use of ARE within minutes!
