Visualizing the Taskcluster Index
I've been working on trying to organize the Taskcluster index in bug 1133074. The index is analogous to the directory structure that we have on ftp.mozilla.org, but it is much easier to organize things based on how we'd like to access them. In FTP, our upload scripts actually ssh into the ftp server and copy files around into the layout we want. But with Taskcluster indexing, we can just add a new route and now we can organize things by revision, platform, branch, or however we'd like.
However, the sheer amount of things we build still makes this tricky. I pulled down the build logs for all the mozilla-central builds I could find, and ended up with 106 builds from buildbot/mozharness (including nightlies and l10n), and 16 builds from Taskcluster. That's a lot of routes to get organized into a usable hierarchy!
Combining Nodes in Graphviz
Graphviz is a handy tool for making graphs. The "dot" command in particular is great for drawing dependency graphs, though for many real-world scenarios there are simply too many nodes to generate a useful graph. In this post, we'll look at one strategy for automatically combining similar nodes so that a more understandable dependency structure is revealed.

We've been going about this all wrong. I blame myself.
