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.

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

11.7 RingLibSDL
Ring 1.0 provided RingAllegro to be able to create games using the Allegro game programming library
Now Ring 1.1 provide RingLibSDL also so we can have the choice between Allegro or LibSDL
Example:
Load "libsdl.ring"
SDL_Init(SDL_INIT_EVERYTHING)
win = SDL_CreateWindow("Hello World!", 100, 100, 640, 480, SDL_WINDOW_SHOWN)
SDL_Delay(2000)
SDL_DestroyWindow(win)
SDL_Quit()
See the RingLibSDL Chapter.
11.8 Demo Project - Game Engine for 2D Games
In practice we would create a game engine in a language like C/C++ to get the best performance then provide Ring
classes to use the engine.
But many 2D Games are simple and creating a game engine in Ring will be fast enough in many cases
Also this would be a good demo project to learn about the language concepts where we build things using Object Ori-
ented Programming (OOP) then access the power that we have using declarative programming using nested structures
or using natural programming.
In this project we selected the first way (declarative programming using nested structures)
Example:
Load "gameengine.ring" # Give Control to the Game Engine
func main # Called by the Game Engine
oGame = New Game # Create the Game Object
{
title = "My First Game"
text {
x = 10 y=50
animate = false
size = 20
11.7. RingLibSDL 152
3. Ring Documentation, Release 1.8
file = "fonts/pirulen.ttf"
text = "game development using ring is very fun!"
color = rgb(0,0,0) # Color = black
}
text {
x = 10 y=150
# Animation Part ======================================
animate = true # Use Animation
direction = GE_DIRECTION_INCVERTICAL # Increase y
point = 400 # Continue until y=400
nStep = 3 # Each time y+= 3
#======================================================
size = 20
file = "fonts/pirulen.ttf"
text = "welcome to the real world!"
color = rgb(0,0,255) # Color = Blue
}
Sound { # Play Sound
file = "sound/music1.wav" # Sound File Name
}
} # Start the Events Loop
See the “Demo Project - Game Engine for 2D Games” chapter.
11.9 RingSQLite
Ring 1.0 provided support for ODBC to use any database and provided native support for MySQL.
Now Ring 1.1 provide native support for SQLite database too.
Example:
oSQLite = sqlite_init()
sqlite_open(oSQLite,"mytest.db")
sql = "CREATE TABLE COMPANY(" +
"ID INT PRIMARY KEY NOT NULL," +
"NAME TEXT NOT NULL," +
"AGE INT NOT NULL," +
"ADDRESS CHAR(50)," +
"SALARY REAL );"
sqlite_execute(oSQLite,sql)
sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
"VALUES (1, 'Mahmoud', 29, 'Jeddah', 20000.00 ); " +
"INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
"VALUES (2, 'Ahmed', 27, 'Jeddah', 15000.00 ); " +
"INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY)" +
"VALUES (3, 'Mohammed', 31, 'Egypt', 20000.00 );" +
"INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY)" +
"VALUES (4, 'Ibrahim', 24, 'Egypt ', 65000.00 );"
sqlite_execute(oSQLite,sql)
aResult = sqlite_execute(oSQLite,"select * from COMPANY")
11.9. RingSQLite 153
4. Ring Documentation, Release 1.8

11.10 Better Code Generator for Extensions
We are using the code generator (written in Ring) every day to add new libraries to Ring.
The generator is used to create RingQt and RingAllegro
Also in Ring 1.1 it’s used to create RingLibSDL.
more features are added like
• Set/Get structure members (numbers & pointers)
• Using constants
• Better Generated Code
See the Code Generator chapter.
11.11 Using Self.Attribute in the Class Region to define new at-
tributes
We can use Self.Attribute in the Class Region (after the class name and before any methods) to define new attributes.
class Person
name # Define name as attribute if it's not a global variable
address
phone
class person2
self.name # Must Define the attribute
self.address
self.phone
11.12 Using This.Attribute in nested Braces inside the Class Methods
We can use nested braces {} while we are inside methods to access another objects, In this case the current object
scope will be changed while we are inside the brace and Self will point to the object that we access using braces {}. In
this case we can use This.Attribute and This.Method() to access the object that will be created from the current class.
Check the Object Oriented Programming chapter for more information.
Also Check the Weight History Application in GUI Development using RingQt chapter.

• Language Reference
• Scope Rules
• FAQ
And more!
