Honestly, I don't care a whole lot about how the dashboards are
implemented so long as they get done and they get done relatively
quickly.

I was thinking that a static site generator would work around the need
for auth and interface code to create new dashboards. We could just
have a git repo with yaml files and if someone wanted a new dashboard,
they could just submit a PR with the new yaml file.

This is meant as an initial direction, not a final resting place. I
fully expect that the functionality will continue to evolve if we adopt
the project.

Why can't all that be hardcoded for now, at least? The required checks
and arches don't change very often.

Again, this wasn't intended as a final spec but as a starting point. If
at all possible, I want to have something which can be shown off as at
least a demo before devconf. With that in mind, I'd like to keep

The motivation is to enable more complex visualizations of results. If
we're interested in the current state of all ruby packages or all
python packages it's not all that easy to see that at a glance with our
current resultsdb interfaces.

I can also see having a dashboard for all critpath packages or all
packages needed for building a livecd being a useful thing to render

The idea was to start with static site generation because it doesn't
require an application server, is easy to host and likely easier to
develop, at least initially.

Sure but then someone would have to write and maintain it. The things
that drove me towards static site generation are:

 - easier to make something quickly

 - enables easier dashboard contribution; we just need the description
   of what's being visualized.

I was thinking more of the example yaml that's in the git repo at
taskdash/mockups/yamlspec.yml [1] but I'm not really tied to it strongly
- so long as it works and the format is easy enough to understand.

Maybe but I think those features can be added later. Are you of the
mind that we need to take those things into account now?

For now, the latest results. In my mind, we'd be running the dashboard
creation on a cron job or in response to fedmsgs. At that point, we'd
date the generated dashboards and keep a record of those without
needing a lot more complexity

> * How are Task dasboards related to Static dashboards [3]

They're the same thing - a demonstration of me somehow forgetting that
there was a basic ticket when I wrote T738.

Thanks for taking this on, it'll be great to have some nicer status
displays of the kinds of checks running in Taskotron.

I guess that depends on what you mean by the technical audience.

Other than people who are steeped in QA day in and day out, I can see
several audiences:

* Volunteer packagers who have hit a failed check and are trying to
  dig out what it means.

* Users who are following a particular package or an issue they've
  encountered

* Anyone in the project who wants to have some task automated and have
  results that are shareable. I'm thinking right now of the planned
  Docs engine (where a git commit triggers an a build or a translations
  update triggers a cache refresh, and then the build results are
  pushed to another git repo which backs a static web site)

* People not currently in the project who we want to impress and
  entice into becoming contributors with our awesome and easy-to-use
  tooling. 

* Me, trying to get an overview of the current state of Fedora activity
  :)


Is this what you are looking for?
