APL ∊ BCN

APL ∊ BCN logo.

APL ∊ BCN is a user group based in Barcelona started by Michail Liarmakopoulos in late November 2021. Its activities are currently exclusively online due to the continuing impact of the COVID-19 pandemic, but plans exist for transitioning to regular physical meetups in Barcelona every second month, with additional online events every one–three months.

It is the first user group based in a country where Spanish is the majority language, but meetings will be held in English to be as accessible as possible.

Goals

The group was founded with the goals of:

• spreading knowledge of APL and the array family of programming languages.
• spreading knowledge about Ken Iverson and other people involved in the development of APL.
• sharing knowledge related to the intersection of mathematics and programming.
• fostering a friendly community of people interested in array programming.

Meetings

The group organizes three distinct types of meetings: general meetings, a historical APL paper reading group, and a general reading group.

For the Zoom sessions password feel free to reach out to the organizer (contact details can be found in the group's official website).
