How hard can it be testing your iOS apps? Is TDD a utopian scenario for you yet? That might be because of the architecture that you are using. During this talk, I explain how using the SOLID principles and a good architecture can help you to do real Test Driven Development. But don't worry, this talk is not only about theory, I point out some real examples of common problems when testing your apps and explain how the Clean Architecture and Swift come to the rescue in those scenarios.

There is ongoing confusion, and some contention, over the right way to use the QThread class. Part of the confusion comes from the uniqueness of QThread, which is significantly different from other threading classes. There are two valid patterns of QThread use, and each pattern is best suited for different use cases. Errors will arise when mixing these two patterns, or applying them inappropriately.
This presentation will look at different patterns of threading in general, and examine in detail the two usage patterns for QThread. This talk will also cover how QThread works inside, how to communicate between threads, provide examples, and point out the pitfalls to avoid.

Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?

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.
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.
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.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

The Ring programming language version 1.8 book - Part 14 of 202
1. Ring Documentation, Release 1.8
We can print the variables values
We can change the variables values then continue execution
We can run the Interactive Debugger in the Output Window
7.15. Trace Library and Interactive Debugger 101
2. Ring Documentation, Release 1.8
7.16 More Syntax Flexibility
• Using braces { } in Packages/Classes/Functions
Example:
load "stdlib.ring"
import mypackage
new myclass {
myfunc()
}
package mypackage
{
class myclass
{
func myfunc
{
print("Hello, World!n")
}
}
}
• Using ‘end’ keyword after Packages/Classes/Functions
Example:
import mypackage
new myclass {
myfunc()
}
7.16. More Syntax Flexibility 102
3. Ring Documentation, Release 1.8
package mypackage
class myclass
def myfunc
put "Hello, World!"
end
end
end
• Using ‘endpackage’/’endclass’/’endfunc’ keywords after Packages/Classes/Functions
Example:
import mypackage
new myclass { myfunc() }
package mypackage
class myclass
func myfunc
see "welcome" + nl
endfunc
endclass
endpackage
7.17 Type Hints Library
Ring 1.5 comes with the Type Hints library
Using this library we can add the type information to the source code which will be very useful for tools like
• Code Editors
• Static-Analysis
Example:
load "typehints.ring"
see sum(3,4) + nl ;
see sayHello("Mahmoud");
int func sum(int x,int y) {
return x+y ;
}
string func sayHello(string name) {
return "Hello " + name ;
}
The library is very powerful and support the User types (Classes) automatically!
Example:
load "typehints.ring"
import mypackage
test() { main([:one,:two,:three]) }
7.17. Type Hints Library 103
4. Ring Documentation, Release 1.8
myclass func test() {
see "Testing User Types!" + nl
return new myclass
}
package mypackage {
public class myclass {
public static void func main(list args) {
see "welcome" + nl
see args
}
}
}
Also You can use the types inside the code (not only the function prototype)
Example:
load "typehints.ring"
int sum = sum(3,4)
string msg = sayHello("Mahmoud")
see "Sum = " + sum + nl + msg + nl
int func sum(int x,int y) {
return x+y ;
}
string func sayHello(string name) {
return "Hello " + name ;
}
Rules:
• To use the types in the function prototype, You must use ‘(‘ and ‘)’ around parameters
• To use the types in the function code, You must set the variable value (Assignment).
Note: Ring is a dynamic language, No type checking will be done by the compiler.
