This week I had a discussion with my open source students in order to get a sense of where people were at with their work. One of the questions I had for them was, "What are you struggling with, what are you finding tricky?" Here's some of what…
I love Service Workers. I've written previously about my work to use them in Thimble. They've allowed us to support all of the web's dynamic loading mechanisms for images, scripts, etc., which wasn't possible when we only used Blob URLs. But as much as I love them, they add a…
Today one of my students wanted some help understanding how to solve a problem with git. I often find that students get stuck on the proper use of git's rebase, merge, pull, and fetch. They want to share and use commits from other repos, but can't quite get the commands…
Yesterday, on Remembrance Day, I travelled to Stratford to attend the funeral of my colleague and friend, Jordan Anastasiade. He passed away suddenly a few weeks ago, and I've been deeply saddened by it. Yesterday was filled with tears and hugs with many colleagues, and his friends, and family. I…
This week I've been thinking about ways in which GitHub could do a better job with projects and code as they age. Unfortunately, since technology is fundamentally about innovation, growth, and development, we don't tend (or want) to talk about decline, neglect, or endings. GitHub has some great docs on…
This week I'm talking with my open source students about bugs. Above all, I want them to learn how The Bug is the unit of work of open source. Learning to orient your software practice around the idea that we incrementally improve an existing piece of code (or a new…
Let me start by saying that I'm a huge fan of open source projects putting a Good-First-Bug type label on issues. From my own experience over the past decade trying to get students engaged in open source projects, it's often a great way to quickly find entry points for new…
tldr; During the spring and summer, I've been working on rewriting Thimble to use Service Workers and CacheStorage. Now that we've shipped it, I wanted to talk about how it works and what I learned. On Twitter a few weeks back, I was reminiscing with Dave Herman and Brendan about…
Yesterday I was fixing a bug in some IndexedDB code we use for Thimble's browser-based filesystem. When I'm writing code against an API like IndexedDB, I love knowing the right way to use it. The trouble is, it can be difficult to find the proper use of an API, or…
I've spent hours this week helping students fix problems with their git repos. I've now seen the same types of things happen frequently enough, that I thought I'd offer some advice on how to avoid falling down a git-sized hole. Git does exactly what you tell it to do, regardless…
