Writing easy to maintain code – a talk by Jeroen De Dauw

A talk by Wikimedia’s very own developer and Software Craftmanship advocate Jeroen De Dauw about how to maintain code.
A significant amount of time is spend on reading code, sometimes more than on writing code. Jeroen asks questions like how does elegant code tend to rot over time, and what can developers do to prevent that? In this short talk, a series of common pitfalls and ways to avoid them will be outlined. Specific tipps show how you can apply the useful ideas for maintaining code right away.

You can find more on Software Craftmanship on Jeroen’s website.

MissingNo., my favorite Pokémon, a talk by Igor Wiedler

The Pokémon series featured some spectacular glitches that can teach us a lot about programming, computers and distributed systems. Igor Wiedler enthusiastically talks how users can gain the opportunity to change outcomes by applying the act of programming as a subversive measure, when programs diverge in unexpected ways.  Breaking the rules can open up new worlds! Especially in the world of Pokemon. If you want to know how, then watch this talk.

Struggle with death or how I survived my Fitbit – a talk by Andrea Knabe

As a non-coder but very enthusiastic about technology, Andrea Knabe encourages non-programmers to start coding. She talks about her very inspiring action of re-programming Fitbit (fitness tracker app) to modify it according to her needs. Fitness trackers are focused on weight loss and encourage to be more active. However, that is not always useful. When you are unable to eat, have no hunger and loss of appetite, the aim is not to lose weight but is not to die. Andrea shows how technology can work against you and what you can do to change that. Watch in this video how she changed the Fitbit app to work to her advantage

My favorite Open Data things by Walter Palmetshofer

Open Data is the idea that some data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control.
Walter Palmetshofer from the Open Knowledge Foundation Germany shows us which great things can be done with Open Data.

About Open Data:

“Ensuring interoperability is particularly important because it allows for different datasets to be conjoined, thus building new, more complex datasets and revealing more insights” (Open Knowledge Foundation, cited in Kitchin, 2014:52).

The unexpected side of web development – Or: I was told there would be no math by Daniela Berger

Daniela Berger talks about a few non-standard web development projects she has worked on in the past. Take a detour through Second Life with Daniela and listen to her stories about being  one of the early Silverlight apps writers – juggling geo coordinates and the matching maths.

How Improv Theater makes me a better developer by Mirko Fichtner

This Tech Talk is about an exciting and new connection – Theater and Software Development.

At EnthusiastiCon 2015 Mirko Fichtner showed how principles of Improvisational Theater relate to Software Development. Prominent examples are the aspect of receiving feedback from the audience or the element of positivity, for example when an actor acts out something that the idea is taken up by all other actors on stage in return. He uses these examples as metaphors to explain his programming experience.  “Impro theater comes out of nothing and turns into magic, just like programming,” he concludes.

Hole-Driven Development in Haskell by Raichoo

“There is a hole in the program, dear Liza, dear Liza” says the developer Raichoo who starts his insightful talk about Hole-Driven Development in Haskell with a bang. However, working with Haskell is more like playing Lego said Raichoo thereafter and tries to narrow down a complicated topic passionately in this talk. Brainy stuff for Haskell and non-Haskell developers.
