Talks: Accessibility for the Web

In this talk, we’ll be talking about designing accessibility for the web – from a developer’s perspective! Despite what we envision, not every user is 100% flawless as far as mental and physical capabilities go – and there’s no excuse for ignoring that. Building an accessible product almost always leads to a much more well-architected product – so it’s a win-win.

In this talk, we’ll discuss the tools and strategies you can use to aid users with visual, auditory, cognitive, and motor impairments. We’ll discuss contrast, colors, content, keyboard flows, screen readers, section 508 – as well as some development concepts such as skip menus, the accessibility tree, hover and focus indicators, ARIA properties, and more.

There’s a lot that developers and designers can do to aid users with impairments – so let’s do it!

Talks: How Blocks Work in Ruby

Watch OKC Ruby, as Aaron Krauss speaks about Blocks.

Ruby has these things called ?blocks,? and they?re one of the key things that make it different from most other programming languages. Often times they take the place of a callback, a lambda function, or even a loop – but they have their own ruby-specific uniquenesses too. In truth, they?re a pretty neat feature that make the language much more intuitive to use – especially for developers new to the language. What exactly is a block, how do you use it, and why would you use it? We?ll answer all these questions in this talk, as well as briefly review Ruby?s other ?callable? structures, Lambdas and Procs.

Talk: Prolog – a Prologue

Watch Tulsa Web Devs, as Aaron Krauss speaks about Prolog.


Prolog is really powerful; it’s a neat old language that’s drastically different from just about any other language out there. It’s not functional (though it is declarative) – but if you’ve never seen it before, it will really challenge how you think about programming languages. For example, there are Sudoku solvers written using just 15 lines of Prolog!

This is a very beginner-friendly talk about Prolog – no prior experience necessary. Together, we’ll learn about facts, rules, and queries in Prolog – the fundamental constructs that make up a Prolog script, and how you can use them to solve some real-world problems.
