A McLuhan-based approach to data architecture

Frank Blau

LanguageEnglish

When Marshall McLuhan said in 1964 that “the medium is the message”, he was primarily speaking about the mediums of print, radio and television. As our industry grows in volume, variety and velocity, this statement remains an important touchpoint for examining our goals and how we create and investigate the content and structures that confront us today. Importantly, the industrial world today functions in what we observe to be a mullti-model ecosystem, with significant needs for harmonization and analytics. What we have learned is that in order to both understand and derive actionable insight from this dynamic world requires the adoption of multi-model techniques and platforms. In this presentation, this evolution and an approach to implementation is outlined and described as an extension of McLuhan’s statement, providing crucial grounding in today’s complex industrial data management landscape.

Code AmountLight

Every day, we face a lot of content, most of which falls into the "junk" category. Investing a lot of effort is necessary to create quality and relevant content that will attract the audience, and even more effort if you want to achieve the "wow effect". Why not seek help from web services that use generative Al to create content?
And what if they could do it from their applications instead of us as users writing a request in the prompt?
This lecture aims to show how content can be created programmatically using the API of these web services!

Code refactoring is something that everybody loves to hate and think of it as a chore or a punishment. While it should be treated as code makeover for which you don't need to hire Mirjana Mikulec :)

I'll start with what is it, why do we do it and continue with a philosophy and theory behind it. After everybody is either asleep or wide awake I'll continue with practical techniques and personal examples.

Are you failing at being agile?

Antonio Perić-Mažar

LanguageHrvatski
LevelIntermediate
Code AmountNone

In these past few years, agile methods became a vital part in the software development process, but are they really applicable for all types of projects and team sizes?

A while ago, our company changed the way we approach project development because the team noticed that standard SCRUM-ish methods aren't fully compatible for us, so we developed our own, modified version of agile. In this talk, I will showcase how powerful this approach is and how you can use it to find problems, and eventually resolve them.

Unveiling WasmCov: Revolutionizing Test Coverage Across Wasm Ecosystems

Noah Jelich

LanguageHrvatski
LevelIntermediate
Code AmountLight

WebAssembly (Wasm) has seen widespread adoption, yet a significant challenge persists—lack of support for comprehensive test coverage solutions like LLVM. In the realm of blockchain, where code vulnerabilities can have severe consequences, relying on automated testing becomes paramount. This presentation delves into the limitations of current test coverage suites for Wasm and introduces an innovative solution - WasmCov. Developed by Noah Jelich and Bartosz Barwikowski at Hacken, WasmCov pioneers the field of Wasm module coverage, providing a robust testing tool to fortify smart contract development in blockchain environments.

Join us as we unveil WasmCov and explore its potential to redefine the reliability and security of Wasm-based smart contracts.

The Flying ActuaRies

Ivan Čuljak

Let's face it – R isn't exactly the star of the cloud computing show. The idea seems straightforward: collect some data, process it, and then store the results. However, transforming a project from "it works on my machine" to a scalable, reliable cloud-based solution presents a real challenge, especially for those like actuaries who haven't chosen coding as their career path.

This tale is about crafting a cloud solution the right way, emphasizing teamwork, exploration, gradual improvement, and how IT professionals can pave the way for actuaries, allowing them to concentrate on their core responsibilities.

In our journey, we chose Azure Databricks as our platform. But there's a twist: the actuaries don't directly interact with Databricks. Instead, we've developed a system that's not only distinct but also more empowering than the standard procedures you might find in an average online tutorial.
