This document provides examples for using the RingZip library to work with zip files in Ring programs. It shows how to create zip files, add and extract files, get file counts and names. The Zip and ZipEntry classes are documented along with their methods. Additional examples demonstrate drawing graphics, animations, handling input, using TrueType fonts, and playing sound files using the Allegro library in Ring programs.
This talk I gave at the 2017 madewithlove retreat (https://2017.mwl.be/) and also at the Maceió DEV Meetup #21 (https://www.meetup.com/pt-BR/maceio-dev-meetup/events/245530346/)
The idea is to compare building the same application in two web frameworks in different languages. One I know and work daily, which is Laravel, and the other one is new to me and I had no experience in Elixir, the language the framework was built in.
The idea is not to compare both languages or frameworks. My goal was mainly learn something new building the same thing twice and see how different languages and frameworks can be used to build similar things.

Elixir & Phoenix – fast, concurrent and explicitTobias Pfeiffer
Elixir and Phoenix are known for their speed, but that’s far from their only benefit. Elixir isn’t just a fast Ruby and Phoenix isn’t just Rails for Elixir. Through pattern matching, immutable data structures and new idioms your programs can not only become faster but more understandable and maintainable. This talk will take a look at what’s great, what you might miss and augment it with production experience and advice.

In this talk, I’m introducing Pegomock, a mocking framework for Go, that I have written over the last 2 years. By quickly going through the idea of Dependency Injection, I'm explaining why mocks are useful in general. Afterwards, I'm diving a bit deeper into how to use Pegomock and why I think it is better than its alternatives.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne

GRAPHICS AND 2D GAMES PROGRAMMING USING RINGALLEGRO
In this chapter we will learn how to use the allegro game programming library in our Ring applications.
We have the file gamelib.ring that load the DLL library that contains wrappers for the Allegro functions
Load "allegro.rh"
Loadlib("ring_allegro.dll")
The file gamelib.ring uses the Load instruction to execute the file allegro.rh which is a ring source code file con-
tains constants to be used in our programs. Then using the function LoadLib() we can load the DLL library
“ring_allegro.dll”.
To write portable code we can change the gamelib.ring to check the platform before loading the DLL/So file.
50.1 Drawing, Animation and Input
The next example uses the Allegro library for drawing, moving objects on the screen and getting input from the
keyboard and the mouse.
Load "gamelib.ring"
al_init()
al_init_image_addon()
display = al_create_display(640,480)
al_show_native_message_box(display, "Hello", "Welcome",
"Using Allegro from the Ring programming language",
"", 0);
al_clear_to_color(al_map_rgb(0,0,255))
BOUNCER_SIZE = 40
bouncer_x = 10
bouncer_y = 20
bouncer = al_create_bitmap(BOUNCER_SIZE, BOUNCER_SIZE)
al_set_target_bitmap(bouncer)
al_clear_to_color(al_map_rgb(255,0,255))
for x = 1 to 30
bouncer_x += x
bouncer_y += x
