We've all been there. You're starting a new job, and you don't even know where the bathroom is, much less all the tools and processes necessary to get that job done. Onboarding in an open organization can be even trickier because of its unstructured environment and open culture. It may be up to you to define your role, and priorities can change quickly.

On the low end, we’ve seen products like the recent, Raspberry Pi Zero W […]

The world is fundamentally generative, as it is created by physical, biological, and chemical processes. But it isn't comprised of clean mathematical lines; rather, it is a struggle between mathematical patterns and entropy. Generative art reflects both aspects of reality, offering a unique perspective on the world. read more

Open-source software can profitably bring rivals together.

Computers were first invented to do math, and they do it really well. But it didn't take long for users to repurpose their futuristic calculators into fancy, dynamic typewriters. Now human-readable text drives computing, so it's important to choose the right format for the text you write. read more

Once upon a time, I wanted to be an evolutionary biologist. To make a long story short, I had a change of heart and dropped out of my PhD program to pursue a career in computer science. I'm now a senior software engineer at Red Hat, where I work on a variety of machine learning and data science projects (you can read more about my journey on my blog). read more

My day job pays me on the 15th and last day of every month, unless those days land on a weekend, in which case I get paid the Friday before. With those rules, creating a Google Calendar event is shockingly difficult. In fact, it's not possible to create a recurring event with those rules using Google's GUI scheduling tool.
