Doodle sketching in Compose mobile and desktop

Do you remember the freedom of doodling without knowing what the outcome would be? What if this were possible in a coding framework such as Compose? This talk explores experimenting with still visuals and animations using Jetpack compose for Android and Desktop.

We will look at:

- How the animation loop works
- Basic drawing features available in Jetpack
- Compose and differences between mobile and desktop
- Useful add on libraries for creative coding with Jetpack Compose
- Some inspirations to kickstart our doodles
- Live code demo

duration: 40 min
target audience: Beginner to intermediate Compose and creative coding enthusiasts
This talk was presented online as a workshop for IWD Nairobi 2023

90s Website … in 2023 on mobile in Compose … for science

Why would anyone build something with a 90s website aesthetic - in Compose? Nostalgia? For one the 90s website aesthetic made heavy use of animations and visual effects. So emulating this style will take any animation framework through its paces. This talk will take some of the most iconic 90s website elements and demonstrate how to reproduce them to build a retro mobile experience using Jetpack Compose.

I can’t promise the end result will have a good user experience but I can promise a good look at the animation system in Compose and a collection of cheesy code snippets.

duration: 40 min
target audience: Beginner to intermediate Compose enthusiasts
This talk was presented at Android Makers 2023, droidcon NY and droidcon London

Imperative, declarative, object oriented, functional: four of a Kotlin kind

Humans have small working memory but good pattern matching skills. The problems we want to solve are large and complex. How can the approach we take make it easier to deal with complexity, especially if the approach is supported by the language we choose.

This talk is a comparative view of four interrelated programming paradigms: imperative, declarative, object oriented and functional - from a Kotlin perspective.

This talk will cover in depth details of the language features that are especially suitable for each of the paradigms. It will highlight how each language feature helps to deal with complexity.

This talk may also contain:
* brief definitions
* snippets of software history

A simplified version of this talk was presented at the I code Java conference in person in South Africa. It is suitable for intermediate Kotlin audiences. This talk was presented at appdevcon 2023
