Python Pip VCS Install from Private github Repository using the Subdirectory Argument

Woah ... that title is a mouthful. Lemme break it down: My python package(s) are in a private github repository (e.g. http://www.github.com/safijari/my_repo) The correct setup.py file is not in the root folder of the repo. (e.g. it's actually located at my_package/setup.py) I want to install it directly from github using pip. I use an ssh …

OpenCV + IPython.display == 😃

I love IPython notebook. The REPL nature with persistence of richly formatted output, plotting, remote notebooks, markdown comments/thoughts/explanations interspersed with code, and so much more. It all wonderfully comes together and elevates my ability to think through new problems and new domains to a whole new level. Then I learned about the IPython.display module ... …

The Why and How of Python Properties

It's nice, and makes a lot of sense in the personal computer interfacing with a ROS enabled robot context. My first exposure to ROS was in 2014 as I started doing some graduate work with …

Fixing “Arduino cannot run because it could not create a folder to store your sketchbook”

Today at work I was trying to install the Arduino IDE on my computer and kept running into this issue. This is very annoying as it keeps the IDE from even starting, so you can't go into the settings and change the default sketchbook folder. The problem was the fact that, this being a work computer, a …

Fixing the Gazebo 2.2 Virtual Machine Depth Ordering Bug

So, there's this bug in version 2+ of Gazebo that pops up only in Virtual Machines (very likely a bug with OGRE rather than Gazebo, actually). It causes camera sensors in Gazebo to output an image where some objects that are supposed to be behind others to get rendered in a way that they appear …
