How do I add a `UNIQUE` constraint?

Have you watched any TV shows recently you want to discuss? Any shows you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their weekend. Did you make any plans? Take a trip? Do nothing at all? Tell us about it!

So much for being a privacy conscious site /s

Anyway, my default setting is activity for the last 7 days mainly for the weekly recurring threads, otherwise I'd probably use 3 days.

(Mildly offtopic but an option to separate recurring threads from normal threads might be nice, since if you're using a shorter period for stuff to show up on the homepage, the weekly recurring threads which should be used/active for the whole week kind of don't.)

This thread is posted weekly - please try to post relevant content in here, such as news, updates, opinion articles, etc. Especially significant updates may warrant a separate topic, but most should be posted here.

This thread is posted weekly, and is intended as a place for more-casual discussion of the coronavirus and questions/updates that may not warrant their own dedicated topics. Tell us about what the situation is like where you live!

Arguably the most important film never made, Jodorowsky's Dune has influenced an entire generation of movie makers despite being never shot. Jodorowksy has HR Giger, Chris Foss and Mobius on design, Pink Floyd on music, Mick Jagger, David Carradine, Udo Kier, and Orson Welles in the cast and even secured Salvador Dali to play the Emperor (Dali refused to read the script and wanted $100k/hour to appear). Jodorowsky wanted to make the film 10-12 hours long, and that's what he pitched. A multi-million sci-fi epic like nothing which had ever been made before. So obviously, nobody funded it.

However, he did make his handbook, The Dune Bible, (link goes to the most complete archive I've seen of scans/captures from the book) of which two known copies still exist. A lot of the design work made it into Lynch's film. Other directors have seen the book too, including, I'm sure, Denis Villeneueve who will hopefully be taking some pointers while making his film.
