Show and Tell

We value learning new things and sharing our knowledge, so we take time each week to share with one another what we've discovered or figured out. We realize that this may be of interest to people outside Agaric, especially those who work alone or are in organizations that do not encourage skill-sharing. Thus, we are inviting partners, students, colleagues—and you—to take part in watching or giving short presentations.

Once a week we gather at Canopy City 14 Tyler St. Somerville (, to share things we know, in person. We also meet online (see the calendar below) and we host presentations by developers, with each presentation usually 5 to 15 minutes long. If you cannot join us in person, there is a link below to the online chat experience, just click on the image.
In the past, Show and Tell topics have ranged from migrating HTML into Drupal to bookkeeping with GnuCash to making Drupal administration easier with Filter Permission module to chatting Off the Record to starting with the Pelican Python-powered static site generator.

When we plan the next event, a calendar with upcoming Show and Tell dates will appear here.

We hope you'll join us at Canopy City Coworking- 14 Tyler Street, Somerville, MA, USA.
