Shiny is a web application framework for R that allows users to build interactive web apps and dashboards. It makes R analyses more accessible by enabling live, shared, and interactive experiences. With Shiny, users write the user interface in ui.R and the server logic in server.R. Basic demos showed how to link inputs like text boxes and dropdowns to outputs like text and plots. Shiny supports all R graphics and its reactive programming allows automatic updates. This enables exploration of data and parameters. Integrations with JavaScript libraries like d3 allow highly interactive visualizations.

TDD and mobile development: some forgotten techniques, illustrated with AndroidCodemotion
"TDD and mobile development: some forgotten techniques, illustrated with Android" by Matteo Vaccari
Delivering updates with confidence; shortening time to market; writing clean and correct code every day: this is the promise of Test-Driven Development. But, it’s not easy to do TDD in Android. You have to run the tests on the device, or install a complex framework that mimics the Android APIs. Both options slow you down. In this session we’ll get back to the roots of TDD and show how to deal with this problem. We’ll learn time-tested techniques that reduce the need to run tests on the device. The good side-effect is that our code becomes simpler and better.

Architecture for applications that scales. It uses redux pattern and ngrx implementation with effects and store.
It's refreshed (but still 2+) presentation from my inner talk for colegues.
It's refreshed again and extended by quick and dirty introduction to Angular with verbose example.
In this event we will walk you through best practices and the practical Implementation of the following topics:
Advantage of Kotlin over Java, Kotlin Coroutines .
What’s new in Android Studio, How to use Motion Layout Editor
NaviGation Architecture component, Vivewmodel, Livedata, Room database, Jetpack Compose,
Material Design Library...etc
App Distribution - Android App bundle over an APK
This course teaches you the concepts of Angular. You will learn how to utilize Components, Annotations, Views, Event Handlers, Directives and more. In Angular everything is a Component and this course takes a component-centric approach. We will use Components as the main point of discussion and you will learn about other concepts in Angular in the context of Components.
In this Episode of this series we will introduce some template awesome syntax of the angular 2. We will know about the life cycle of the component and when to use or not to use its life hooks. Also We will introduce the directives and it's types. We will introduce about Forms with the Angular way. I hope enjoy learning these stuff :D.
The aim of these series is exploring Angular 2 and it's amazing features. with the simplest way and the meaningful examples and labs to be practiced. Good Luck in Exploring :D
"Reactive Programming with JavaScript" by Giorgio Natili
JavaScript is an asynchronous and almost single-thread language. Learning how to manage its asynchronous nature is perhaps the most important part of becoming an effective JavaScript programmer. Reactive programming tools in JavaScript provide a powerful way of “wrapping” the asynchronous callbacks into a more readable and maintainable code base. In this talk, I'll highlight the pros and cons of different reactive programming approaches and practices by demonstrating how to use Redux and Angular 2.x as the building blocks of a scalable architecture for your web app.
Home Improvement: Architecture & KotlinJorge Ortiz
Two of the most relevant news from the recent Google IO were the Guide to App Architecture and the adoption of Kotlin as a first-class language. Both have a very positive impact in our applications.
In my talk I introduced and advanced architecture inspired in the Clean Architecture of Uncle Bob and I showed the impact of these two elements.
First I mentioned the components provided for integration with the lifecycle and how that saves a lot of effort to preserve view models or presenters. I briefly covered the methods that we had available until know focusing on the use of a fragment with no view that had the retained instance property set to true.
Then I covered some real scenarios explaining the improvements that Kotlin provide us with. Some examples:
- Conciseness of data classes (and limitations)
- Property observation
- Use of extensions in presentation logic
- Sealed classes for results (as an either-like type)
This is a "Code or it didn't happen" (TM) talk. ;-)
what happens when we open a react native app? Lets learning together how react native work, lets see between basic theory and modules to make your life easier.
Writing infinite scalability web applications with PHP and PostgreSQLGabriele Bartolini
PostgreSQL 9.2 introduced native support for the JSON data type, as well as V8/Javascript and Coffeescript procedural languages.

Introduction to interactive data visualisation using R Shinyanamarisaguedes
Shiny is an R library for building interactive webapps. Shiny allows rapid prototyping and quick production of dashboards and interactive data visualisations. This is especially important in situations where putting a real data-driven prototype in the hands of the end user allows for better refining of requirements before passing off to a web development team. This allows to speed up the delivery process and reducing the dependencies on other teams.

Gary Bradski, President and CEO of the OpenCV Foundation, presents the "OpenCV Open Source Computer Vision Library: Latest Developments" tutorial at the May 2015 Embedded Vision Summit.
OpenCV is an enormously popular open source computer vision library, with over 9 million downloads. Originally used mainly for research and prototyping, in recent years OpenCV has increasingly been used in deployed products on a wide range of platforms from cloud to mobile.
The latest version, OpenCV 3.0 is currently in beta, and is a major overhaul, bringing OpenCV up to modern C++ standards and incorporating expanded support for 3D vision. The new release also introduces a modular “contrib” facility that enables independently developed modules to be quickly integrated with OpenCV as needed, providing a flexible mechanism to allow developers to experiment with new techniques before they are officially integrated into the library.
In this talk, Gary Bradski, head of the OpenCV Foundation, provides an insider’s perspective on the new version of OpenCV and how developers can utilize it to maximum advantage for vision research, prototyping, and product development.
There are two different schools of TDD: the "London School of TDD" ("Mockists") with proponents like Steve Freeman, Nat Pryce, J.B. Rainsberger leverage a top-down approach and heavy use of interfaces to craft roles of neighbour objects. They drive their design "outside-in" starting with end-to-end acceptance tests and focus on the interaction between objects. Testing them in isolation is achieved by heavy use of mocking.
On the contrary the "Chicago School of TDD" ("Classicists" like Kent Beck, Uncle Bob, ...) try to avoid mocks if possible. They prefere "state based testing" and focus on assertions on the return values.

How to lock a Python in a cage? Managing Python environment inside an R projectWLOG Solutions
Presentation from a workshop delivered by Piotr Chaberski during PyData Warsaw Meetup on Feb. 06, 2018.
Imagine that you are developing a project using R and your big corporate customer, after weeks of processing requests to establish open-source analytical environment, finally managed to install R on their production machines. Now you realized, that it would be nice to use some Python library in your solution...
How would you tell the client to switch to Python for a while?
Everything You Should Know About the New Angular CLIAmadou Sall
The Angular CLI is a powerful tool that makes it easy to build Angular applications. With the Angular CLI, we can scaffold, develop, test, and build our applications. It's the best starter kit for Angular projects.
Since version 6, more powerful and more generic, the Angular CLI has introduced plenty of great features like workspaces, architects, builders, library support, and my preferred, schematics. Angular Schematics are the main focus of this presentation. It allows us to create our custom blueprints, add a framework and its setup to our application via a single command, and to update/migrate our application.
After this session, you will have a big picture of the new Angular CLI features including:
• workspaces,
• library support,
• architects,
• builders,
• how to create your own Schematics,
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Thursday, August 22, 13
6. First Demo
library(shiny)
shinyUI(
textInput("who","Reviewed
by","nobody"),
selectInput("rating",
"Rating"
c("Hard","Easy")),
h1(textOutput("review"))))
library(shiny)
shinyServer(function(input,
output)
{
output$review
<-‐
renderText({
paste(input$who,
"thinks
shiny
is",
input$rating)
})
ui.R
server.R
always use library(shiny)
at the start of ui.R and
server.R
Thursday, August 22, 13
13. First Demo - Review
• html input “who” is linked to R input$who
• R output$review is linked to html #review
• updates re-evaluate code automatically
• no javascript knowledge required
• this is the Function Reactive Web-server at
work
Thursday, August 22, 13
14. First Plot
shinyUI(div(
numericInput("binwidth","Bin
width",1),
selectInput("measurement","Measurement",
c("mpg","hp")),
plotOutput("myplot")))
shinyServer(function(input,
output)
{
output$myplot
<-‐
renderPlot({
print(ggplot(data=mtcars,
aes_string(x=input$measurement))+
geom_dotplot(binwidth=input$binwidth))
})})
ui.R
server.R
Here ggplot2 needs to be
‘required’ at the start of
server.R only.
Thursday, August 22, 13
16. First Plot Review
• Shiny supports all R plot types via ‘PNG’
• renderPlot foo is linked to plotOutput #foo
• Anything can be parameterised - numbers,
strings, functions, columns, methods, code
• Enables powerful ‘exploration’ of design
parameters for you
• Enables final user to adjust parameters
Thursday, August 22, 13
17. Live, Shared, Explored
Shiny reports are
live because the R
is executed every:
session
user
input
...continuously
DEMO
Thursday, August 22, 13
18. Live, Shared, Explored
Your reports are shared because:
Your whole team can see the most recent
version of the report - just share the URL
Your whole team can get involved in the
analysis
You can save and share where you navigated to
(* extra work required)
Thursday, August 22, 13
19. Live, Shared, Explored
Using tabs to select between datasets, reports
and visualisation - each with custom inputs and
outputs, you can enable your team to make
new discoveries in the data you already have.
Tabs allow whole new sets of inputs and graphs
to appear - completely customised in R using
ReactiveUI
