Haskell is a demanding language, so you're almost certainly a pretty senior dev. If so, consider volunteering to help organizations during the downtime. Worst case, if you can't get that dream gig back it will certainly make your resume stand out when you're looking for your next thing. Best of luck.

This is aimed at scientists, but my wife is on the list and tells me that they are looking for UX designers and software developers.
I guess if they're also looking for UX designers, they aren't looking for just data analysis code?
Edit: given the subject matter, I imagine there is demand for data analysis expertise, but that is my own speculation.
It would be great if all devs could keep this in mind, but especially the ones that are about to get some time off (if life does not get too stressful for you).
