Nice!  The page only shows completed jobs, not queued jobs, right?

Nice.  The under-the-hood changes you mentioned above are also really
cool, it seems to be a solid base now.

Yay!

That would be great.  In the end, it seems to be that there are quite a
few services we could build around the Data Service.  I’m not sure how
they should interact.

For instance, Mumi could talk to data.guix.gnu.org over an HTTP API, or
should we replicate the database at issues.guix.gnu.org so that Mumi can
tap directly into it?

Likewise, how should something like hpcguix-web (the package browser at
<https://hpc.guix.info/browse>) exploit available data, for instance to
show the history of package versions?

Looks like it’s done now:
<https://git.savannah.gnu.org/cgit/guix/data-service.git>.  :-)

Are there specific areas where you’d like help?  Would you encourage
people to start and hack tools or services that build upon the available
data?

Thank you!
