A Comprehensive Look at Generative AI in Retail App Testing.pdfkalichargn70th171
Traditional software testing methods are being challenged in retail, where customer expectations and technological advancements continually shape the landscape. Enter generative AI—a transformative subset of artificial intelligence technologies poised to revolutionize software testing.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.

Advanced Flow Concepts Every Developer Should KnowPeter Caitens
Tim Combridge from Sensible Giraffe and Salesforce Ben presents some important tips that all developers should know when dealing with Flows in Salesforce.
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?
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
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.

3. What are Constructors?
• A constructor in Java is a block of code similar to a method
that is called when an instance of an object is created
• It is a special method that is used to initialize a newly created
object
• Java constructor is invoked at the time of object creation
• It constructs the values i.e. provides data for the object that is
why it is known as constructor

School
4. What are Constructors – cont.
• Key differences between a constructor and a method
• A constructor doesn’t have a return type (not even void) since
the basic aim is to place the value in the object. If we write the
return type for the constructor then that constructor will be
treated as ordinary method
• The name of the constructor must be the same as the name of
the class
• Constructor definitions should not be static as constructors will
be called each and every time, whenever an object is created

5. What are Constructors – cont.
• Unlike methods, constructors are not considered members of a
class
• A constructor is called automatically when a new instance of an
object is created
5
Method Constructor
Method can be any user
defined name
Constructor must be class
name
Method should have return
type
It should not have any return
type (even void)
Method should be called
explicitly either with object
reference or class reference
It will be called automatically
whenever object is created
Method is not provided by
compiler in any case
The java compiler provides a
default constructor if we do
not have any constructor

6. Need for Constructors
• It can be cumbersome to initialize all variables in a call each
time an instance of a class in created
• Constructors are mainly created for initializing the object
• Initialization is a process of assigning user defined values at
the time of allocation of memory space
• An advantage of constructors in Java is it eliminates placing
the default values

Blue
Ridge
Public
School
7. Need for Constructors – cont.
• Whenever we create an object of any class, memory is
allocated memory for all the data members and their
values are initialized to their default values
• To eliminate these default values by user defined values
we use constructor

9. Types of Constructors
• Based on creating objects in Java, constructor are classified in
two types. They are:
• Default or no argument Constructor
• Parameterized Constructor

10. Types of Constructors – cont.
Default or no argument Constructor
• A constructor that has no parameter is known as default
constructor
• If we do not define a constructor in a class, then compiler
creates default constructor(with no arguments) for the class
• If we write a constructor with arguments or no-argument then
compiler does not create default constructor
Default constructor provides the default values to the object like
0, null etc. depending on the type

11. Types of Constructors – cont.
• Example of default constructor
• In this example, we are creating the no-argument constructor in
the Bike class
• It will be invoked at the time of object creation
class Bike
{
Bike()
{
System.out.println("Bike is created");
}
public static void main(String args[])
{
Bike b=new Bike ();
}
}

12. Types of Constructors – cont.
• If there is no constructor in a class, compiler automatically
creates a default constructor
• The default constructor is a constructor that the Java
compiler adds to your code if no explicit constructor is
available
• If you have added your own constructor (no matter whether
it's without parameters or with parameters) the compiler will
not add the default constructor in this case

13. Types of Constructors – cont.
• Parameterized Constructor
• A constructor that has parameters is known as parameterized
constructor
• If we want to initialize fields of the class with your own values,
then use parameterized constructor
• This type of constructor accepts parameters and initializes the
data members based on the arguments passed to it
• A parameter is a variable in a method definition. When a method is
called, the arguments are the data you pass into the method's
parameters
public void MyMethod(String myParam) { }
...
String myArg1 = "this is my argument"; myClass.MyMethod(myArg1);

14. Types of Constructors – cont.
• Example of parameterized constructor
class Student4{
int id;
String name;
Student4(int i,String n){
id = i;
name = n;
}
void display()
{
System.out.println(id+" "+name);
}
public static void main(String args[]){
Student4 s1 = new Student4(111,"Karan");
Student4 s2 = new Student4(222,"Aryan");
s1.display();
s2.display();
}
}
• In this example, we have created the constructor of Student class that has two parameters
• We can have any number of parameters in the constructor
14
15. Constructor Overloading
• Constructor overloading is a technique in Java in which a class
can have any number of constructors that differ in parameter
lists
• Like methods, we can overload constructors for creating
objects in different ways
• Compiler differentiates constructors on the basis of numbers
of parameters, types of the parameters and order of the
parameters
