Abstract

Intended Audience: Beginner

The talk outlines how a beginner taking the CIS 194 course prepares applying Haskell on real world projects. Take away lessons include what pitfalls to avoid, struggles on might face on the transition from learner to practitioner and how to contribute to the Haskell community.

About myself: Róman is a software engineer at Red Hat, working on internal tools. His every day language is mainly Python. He is using XMonad for almost 6 years but never fully grokked how to configure the window manager and it’s components.Until now.

Personas: Application Development from the Users Perspective

Personas are hypothetical users which you can use when designing features for your application, to anticipate user interaction based on their goals. One of many problems in software engineering is providing consistent and easy to use user interfaces. How do you know what UI enables your users to get things done? How do you find a solution if you have conflicting interests? How do you build an interface, which doesn't leave decisions about configuration of the UI up to the user.

Application Development from the Users Perspective

Short description

The talk gives first hand experience on creating personas - a usability tool for designing user interfaces - and how to incorporate them in the design process.

Long description

Personas are hypothetical users which you can use when designing features for your application, to anticipate user interaction based on their goals. One of many problems in software engineering is providing consistent and easy to use user interfaces. How do you know what UI enables your users to get things done? How do you find a solution if you have conflicting interests? How do you build an interface, which doesn't leave decisions about configuration of the UI up to the user.

This talk will offer a solution to these questions by making use of personas. It will give first hand experience from developing personas for Beaker: from user interviews to how we incorporate them in our design process.

Real World Haskell: A TUI e-mail client

There is a myriad of free software e-mail clients to choose from. However only few support a text user interface and fast indexing.

Talk Outline:

Quick introduction to brick and how to build text user interfaces
How do we extensively test purebred
What have we done to leverage Haskell to build a better client than what is available today
What have we learned so far
