Call the Doctor is a series of weekly, unscripted, live events! The HDF Group’s staff members will answer attendee questions and, for example, go over the previous week’s HDF Forum posts. The HDF Clinics are free sessions intended to help users tackle real-world HDF problems from a common cold to severe headaches and offer relief where that’s possible. As time permits, we will include how-tos, offer advice on tool usage, review your code samples, teach you survival in the documentation jungle, and discuss what’s new or just around the corner in the land of HDF.
Join us every Tuesday at 12:20 p.m. central (US/Canada.) on Zoom!
