I just upgraded mobx-react from 4.0.4 to 4.4.3. In theory, this should not have required any code changes. However, starting in mobx-react 4.1.2, there was something that tickled what I'm guessing is a hidden bug in Enzyme 3.3.0. We had a test that would purposely throw an exception in the render method of a React component. The test was written using shallow. Even once I had gotten the test to pass in mobx-react 4.1.2, it was somehow poisoning something unknown which caused about 0.5% of my other tests to fail. It was perfectly reproducible if I ran all the tests, but running any of them individually would not fail. It was quite baffling. My buddy Kevin figured out that moving from shallow to mount fixed the issue, inexplicably. It's a workaround, but we'll have to just live with it since I have no idea how to find the bug in Enzyme. Note, we're using React 15.6.2 and MobX 2.7.0.
In his keynote at PyCon, Eben Upton, the Executive Director of the Rasberry Pi Foundation, mentioned that not only has Minecraft been ported to the Rasberry Pi, but you can even control it with Python . Since four of my kids are avid Minecraft fans, I figured this might be a good time to teach them to program using Python. So I started yesterday with the goal of programming something cool for Minecraft and then showing it off at the San Francisco Python Meetup in the evening. The first problem that I faced was that I didn't have a Rasberry Pi. You can't hack Minecraft by just installing the Minecraft client. Speaking of which, I didn't have the Minecraft client installed either ;) My kids always play it on their Nexus 7s. I found an open source Minecraft server called Bukkit that "provides the means to extend the popular Minecraft multiplayer server." Then I found a plugin called RaspberryJuice that implements a subset of the Minecraft Pi modding API for B
