In an effort to get some practice using Git, I began reading the documentation and some articles here on Opensource.com, particularly Seth Kenlon’s introductions. Once I finished reading, it was time to do some actual practice. read more

I met a lot of wonderful people and learned a great deal about how the Python community works at PyCon 2019 in Cleveland. But my main technical takeaway has to do with the magic of JupyterLab, which is described as a web-based user interface for Jupyter Notebook, an application "that allows you to create and share documents that contain live code, equations, visualizations, and narrative text." read more

There is a song, artist, genre, and album for everything, whether you're trying to get in the zone or trying to zone out. When you're coding, what does your go-to playlist consist of? Does it mainly contain alternative rock songs with the perfect tempo for optimal productivity? Or do you prefer lyricless music, either classical or electronica, for the times you really need to focus? To balance out the more mundane tasks, do you shamelessly turn to sing-along pop to help pass the time? What tunes do you crave for a creativity boost?  read more

I've been using Nextcloud (and before that, ownCloud), an open source alternative to file syncing and storage services like Dropbox and Google Drive, for many years. It's been both reliable and useful, and it respects my privacy. While Nextcloud is great at both syncing and storage, it's much more than a place to dump your files. Thanks to applications that you can fold into Nextcloud, it becomes more of an information hub than a storage space.

I had high hopes for the GDPR (the EU's General Data Protection Regulation), which famously went into effect one year ago. I even suggested that we re-brand 25 May "Privmas Day" (hashtag #privmas) since I expected the GDPR would go far toward protecting personal privacy online, which prior to that date had been approximately nil.
