Learning DVCS Workflow - 0

If you take look at the revision history for some of my projects on GitHub, you'll see that I have a fairly messy track-record!

A few times I have successfully used Magit's ability to interactively stage/unstage Hunks or parts of Hunks, to make my commits a bit more clean and sensible, but not always.

The real problem is: I haven't been using Branches. It's because I haven't studied how to use them effectively, and in the past they've been scary.

But for the future, and especially for my dotfiles, I'd like to be able to read through the commits and make sense of them after. Also I'd like to be sure when I'm committing that I don't make any unplanned master changes and break things.

I also tend to work by myself on these projects, but I'll often go on a tangent, or start a blog post and then put off finishing it while another, different idea is developed and maybe even published first. Ideally I should be able to track these things separately.

So I need to learn: how to do revision control workflow with branches, properly.

4-bit Rules of Computing, Part 3

Here is the forth part of my blog series expanding on my 4-bit rules of computing.

Previously in Milosophical Me: Mike was reflecting on Comments, both in source code and in social media, and had come to the conclusion that they are to be avoided, that they can be more harmful than helpful, and that source codes (and people) should be allowed to speak for them selves.

There is an exception to Rule 5 (Rule 0 allows for this): doc-comments. In this post I explore what they are, how they differ from regular comments, and how to use them to assist your fellow hackers.

Exploring Minecraft code in Jupyter

Some breif notes from a lazy Sunday morning spent exploring the minecraft coding environment that I set up using Raspberry Jam earlier. I'm taking my notes in Jupyter while I explore the Minecraft API and poke around with one of the sample programs. Since my blogging engine Nikola also supports Jupyter Notebooks as one of it's import formats, I found that I could do Litterate Programming for Minecraft quite nicely!

I've been coming to my sons class when I get a chance and showing the kids about computer codes. I actually started a CodeClub last year and we were pretty successful, though very limited by my availability -- I was able to run the club for one hour most weeks, so it took us two terms to cover Scratch 1.

This year I've had even less time away from work, but I've had great support from the grade 6 teacher. We plan for him to facilitate the projects in class while I assist via emails and blogs. So: here's my first post.
