A quick list of tech meetups I have found useful in Edinburgh. Given the fact that Meetup has announced that it may start charging high prices soon, this list includes alternative methods to stay in contact with the groups.
Edinburgh TechMeetup – General tech and geek meetup covering a broad range of topics on the second Wednesday of every month (disclaimer – I help to run this meetup) – https://www.meetup.com/TechMeetup/ or https://techmeetup.co.uk/or https://opentechcalendar.co.uk/group/1-techmeetup-edinburgh
PyData Edinburgh – Excellent Python-centric data science meetup on the first Thursday of every month – https://www.meetup.com/PyData-Edinburgh/ or https://opentechcalendar.co.uk/group/481-pydata-edinburgh
Edinburgh Data Visualisation Meetup – covers a wide range of data visualisation topics, unfortunately does not appear to have a regular date, but generally late in the month – https://www.meetup.com/meetup-group-vBHbCmgh/ or https://opentechcalendar.co.uk/group/539-edinburgh-data-visualization
Bayes Centre (Edinburgh School of AI) – a variety of talks on AI topics held quite frequently – used to use a meetup group at https://www.meetup.com/Edinburgh-School-of-AI/ now seem to prefer their own site at https://www.ed.ac.uk/bayes/bayes-events/upcoming-events
