This whole weekend the second edition of the Jornadas de Periodismo de Datos will take place in Barcelona, Madrid and Almería, starting today. I’ll be participating with a modest workshop on spreadsheets in Barcelona on Saturday, but the speaker roster is filled with pretty big names in the spanish and latin-american data journalism community. The sessions are streamed online, but if you happen to live in any of the hosting cities, it’s worth attending the sessions on site.
