references - Seeking pgrouting workshop or tutorial?

Please recommend pgrouting tutorials or workshops that are most current.

I ask because I just read a post that claims a tutorial is deprecated. (see osm2po vs osm2pgrouting: workshop post)

I am working through the pgrouting-workshop (http://workshop.pgrouting.org/) and find it mostly helpful.

The OS and environment here: ubuntu 12.04, postgres 9.1, postgis 1.5.

While it may be unreasonable to ask that all deprecated tutorials be so marked, it would help if the date of authorship is included prominently in the header of all training materials, then newbies would know to expect some staleness.
