Speaking at PyCon Canada 2017 on “Python as a Philosophy”

I’m going to be in Montreal this weekend for PyCon Canada to give a talk on “Python as a Philosophy”. It will explore some of the ideas that are part of Python, built into its core and affect its community and how those ideas have spread to other software and software developers:

A number of programming languages that have not been used quite as frequently as others contain “profound enlightenment” that a developer learns through their use. Languages such as Lisp and Smalltalk are in this category. This presentation suggests that Python is also one of those languages. Python and PEP20 The Zen Of Python can affect how a developer writes code and then translates their practice into using other programming languages. For example, my own hands-on programming in Python has allowed me to carry on a number of practices into JavaScript and Ruby. The talk will specifically cover “explicit rather than implicit” code and the value of documentation as a developer-user experience. I will outline several examples and counter-examples of Python-inspired code practices within the context of JavaScript and Ruby.

Update: slides for the presentation are up.

Stylelint: Lint your CSS

When working with CSS, developers usually don’t think about running a linter on the stylesheets. We usually use linters on C or C++ or JavaScript codebases. However, we don’t often think about whether or not it’s even possible to lint a CSS stylesheet and enforce certain coding standards and rules on it.

With Stylelint, you can lint your CSS and make sure it’s in line with common standards, more powerful than that is writing your own stylelint rules.

CSS Needs Linting Tools Just Like Other Languages

Here’s a few reasons why you would want to write your own custom rules for a linting tool:

  • You can make sure the code base is readable and consistent (a necessity for CSS!)
  • You can prevent some mistakes from happening (for example, always using parens around method calls in Ruby or CoffeeScript, or making sure every method has a comment explaining what it does)
  • Linters can warn you of potential issues (to take a Ruby on Rails or Django example, when you’re using the wrong method to get the count of items in the database)

So I sat down and read through the CSS stylelint guide on writing plugins and rules and came up with a basic example that other developers can build upon to lint their own CSS code.

Lessons from “Producing Open Source Software”

The free book, Producing OSS / Producing Open Source Software, is one I’ve referred to now and again when thinking about how free/open source projects should be run and lately I’ve been thinking about how a big company like Red Hat works when they’re based around free/open source projects.

Here are some choice quotes that I think can serve as useful lessons for open organizations.

SEMAT Kernel Example – walking through a small task

I have been reading the SEMAT Kernel book, The Essence of Software Engineering: Applying the SEMAT Kernel, and it provides a new way of managing software development projects. It is supposed to make it easy to check the health of a project by classifying the major components, known as Alpha states in SEMAT, and the progress level that they’re at.
