PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

pkgsrc trunk packages and images

Now that pkgin has refresh support and the macOS trunk builds have proven that a rolling trunk release works well, I am happy to make SmartOS/illumos trunk packages and images available again for testing.

These are rolling builds of pkgsrc trunk every day (or so), providing the latest packages without having to upgrade across quarterly releases. Just install once then pkgin full-upgrade to keep up-to-date.

This is primarily of interest to:

No Compute Resources Available

This error is somewhat ambiguious because there is seemingly no indication which resource is exhausted.

From Job UUID

Triton chooses compute nodes with a subcomponent called sdc-designation (also refered to as , DAPI). The full DAPI log for a provision job is embedded in the CNAPI log file and can be extracted with the workflow job uuid and the following script.
