The fine folks at Open Source Design are organizing on January 31 a practical workshop on usability testing:

https://hsbxl.be/events/byteweek/2020/opensourcedesign/

It will happen in Brussels, 1 day before FOSDEM.

From the author and the description of the workshop I expect it to imply

invaluable knowledge for free.

Everybody interested in developing or designing usable software but without academic training on usability testing should attend a workshop like this.

I'm not sending this email to UX mailing lists on purpose :)
