One interesting advance feature in Conda is the capacity to pin packages from your environments so they can not be updated at all. If you are interested in that specific version of some package and not the next one because it breaks your work completely or for some other reason, you are probably pinning that package. If you are adding the specific version in every command you run instead of pinning the package, you are doing it wrong and you should keep reading ;-)
But, is it possible to pin Conda itself so it does not get updated every time you try to install/update something else?
OK, time to recap some things... As you know, Nikola 7.0.0 was released some weeks ago. It has a lot of improvements, bug fixes and new features. I recommend you to download and try it! As part of the release, we paid attention to update all the plugins and themes inside the Nikola Github organization (don't forget you can contribute with your own plugins and themes!). So, I updated my own themes, in particular, the Zen ones.
Coming back to the nice practice of release my own IPython nbextensions, today I will release two extensions I use a lot in my daily workflow:
writer, useful extensions to load files into the IPython notebook and to write the content to the same (or another) file.
