Here are the key steps for building RingQt applications for mobile:
1. Download the Android SDK Tools and Android NDK from the official Android developer website. The SDK provides tools for app development and the NDK allows you to build portions of apps using C/C++.
2. Configure your development environment by setting the ANDROID_HOME environment variable and adding SDK/NDK paths to your system PATH.
3. Create an Android project in Qt Creator. Choose "Qt Android Application" as the template.
4. Add RingQt source files to your project and import necessary RingQt modules in your code.
5. Configure the project to use the NDK for building RingQt C/C++
Dependency Injection for Android @ Ciklum speakers corner Kiev 29. May 2014First Tuesday Bergen
We are happy to invite you to the Speakers’ Corner today, on Thursday May 29, from 18.30 till 19.30 at SkyPoint to meet Thomas Vervik, Head of Development Bipper Communications who will talk on “How to save money on QA - Dependency Injection and automated testing on Android”
Thomas is Head of Development for Bipper Communications, and has been managing the company's team in Kiev since February 2012. Originally a seasoned Java server backend/frontend developer, he has the last two years started mobile development, first with HTML 5 and later Android.
Mobile development has since its birth around 2008 gone from simple apps to more complex enterprise similar software. The increase in size and complexity yields the need for structuring the code differently in order to handle the new complexity. The tools used to handle this complexity has been applied to server side development for years, but mobile development has been lagging behind.
But not anymore. New frameworks built on proven paradigms are emerging, and in this Speakers Corner we will introduce Dependency Injection for Android, the motivation for its use, and one of the implementations - Dagger. Dependency Injection has several advantages, but in this presentation we will focus on how it enables to write proper automated tests.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

65.61 RingQt Classes and their Qt Documentation
Qt Documentation : http://doc.qt.io/qt-5/classes.html
See the “RingQt Classes and Methods Reference” chapter for supported classes and methods.
65.62 New Classes names - Index Start from 1
We added new classes to RingQt - another version of classes where the class names doesn’t start with the “q” letter
Also updated methods so the index start from 1 when we deal with the GUI controls like
• ComboBox
• ListWidget
• TableWidget
• TreeWidget
These classes are inside guilib.ring under the package name : System.GUI
To use it
load "guilib.ring"
import System.GUI
This doesn’t have any effect on our previous code, It’s just another choice for better code that is consistent with Ring
rules.
Also the form designer is updated to provide us the choice between using classes where (index start from 0) or (index
start from 1)
Example (Uses the Form Designer)
1. https://github.com/ring-lang/ring/blob/master/applications/formdesigner/tests/indexstart/indexstartView.ring
2. https://github.com/ring-lang/ring/blob/master/applications/formdesigner/tests/indexstart/indexstartController.ring

65.63 Creating Reports using the WebLib and the GUILib
The WebLib comes with a class called HtmlPage
Using this class we can create reports quickly using WebLib & GUILib together
Example:
load "stdlib.ring"
load "weblib.ring"
load "guilib.ring"
import System.Web
import System.GUI
new qApp {
open_window(:CustomersReportController)
exec()
}
class CustomersReportController
oView = new CustomersReportView
func Start
CreateReport()
func CreateReport
mypage = new HtmlPage {
h1 { text("Customers Report") }
Table
{
style = stylewidth("100%") + stylegradient(4)
TR
{
TD { WIDTH="10%"
text("Customers Count : " ) }
TD { text (100) }
}
}
Table
{
style = stylewidth("100%") + stylegradient(26)
TR
{
style = stylewidth("100%") +
stylegradient(24)
TD { text("Name " ) }
TD { text("Age" ) }
TD { text("Country" ) }
TD { text("Job" ) }
TD { text("Company" ) }
}
for x = 1 to 100
